"Thanks, babe!" Lucas said, kissing his boyfriend before looking down at the drink that Tyler had prepared for him.

The two 25-year-olds had been working hard to get back into shape after months of lockdowns and being stuck at home. To their surprise, they had come to love the time spent working out at the gym together, even though Tyler worked some evenings and couldn't always join Lucas. The two still checked in regularly with each other, making sure to encourage each other to make their goals. It had been about a month since they started working out, and though they had not bulked up too much thus far, the tone from their workouts was starting to show on their bodies. They figured it was simply the first sign of what their efforts could achieve, motivating them to keep going.

Though they'd been researching the proper meals and shakes to accent their workouts, Tyler had recently found a new protein powder online for his boyfriend to try, one that promised a healthy way to bulk up in tandem with their weight lifting. Though they had started at the same time, Tyler's rate of progress had been noticeably faster, and he'd wanted something to allow for his boyfriend to eventually catch up.

Taking a sniff, Lucas wrinkled his nose, the smell a little off-putting. It wasn't the first protein shake that was not the most palatable, but Lucas had relaxed his gag reflex enough that it usually wasn't an issue. This time his practice had proved useful as he downed about half the drink in one go, seemingly unfazed by the taste, offensive or not.

"I hope it's not too bad, honey!" Tyler said, concern on his face.

"Yeah, it's...not the worst one we've tried!" Lucas said with a slight laugh, observing the rest of the drink before downing it, not wanting the aftertaste to turn him off. It was a little earthy and meaty, but not so much that it made him want to wretch. In fact, the longer he waited, the better the flavor seemed to get. He would have asked for another one, but he knew that Tyler had to go to work and didn't want to overdo it besides.

"I'm glad!" Tyler said, relief on his face. "Have a good time at the gym, honey. I'll see you in the morning!"

"Alright! Love you!" Lucas said, kissing his boyfriend goodbye. He made his way over to the gym, preferring to go when it was a little more crowded so that judging eyes would remain off of him. Though he didn't really mind going alone, he was a little self-conscious about his lean build, especially at the weight machines. His frame could only support so much weight, after all, a fraction of what some other lifting enthusiasts could lift. It was fine when Tyler was there, of course. His love always knew what to say to give him a boost of confidence to make it through a workout.

To his delight, the volume of people present was just enough that it wasn't too crowded so he could find a machine and not look out of place lifting. Lucas donned his workout clothes, heading out to grab one of his favorite machines to start his workout. Curls were the first thing on his list, and Lucas started slow, building up to the higher weights that he and Tyler often did together. He went about his reps, listening to a comedy podcast to try to distract him from his task. The lower weights were never too hard, and they helped him loosen up for the ones that he struggled with.

Yet, before he knew it, his first round of reps was over, and he had not strained himself in the slightest. Lucas smiled at that, looking down at his toned arms with a sense of pride. He had been doing this regularly, after all. It only made sense lifting the lighter weights would get easier, his body having gotten used to them. Tyler would be proud with the ease he did his regular workouts now!

Deciding what the hell, Lucas chose to skip the middleweights, not wanting to waste his time with levels that he had obviously surpassed. He wouldn't go all the way up to what he did with Tyler; that was something he struggled with and would be a little embarrassed if someone saw or even came to offer him some help. But, he figured he could handle the next tier up and set the weights on the bar to begin.

Not bothering to focus on the podcast and more interested in the straining on his arms, Lucas began his set. Lost in the power that he seemed to possess, he was hardly aware that his arms were starting to expand, swelling beyond their formerly meager confines as he easily lifted more than he'd ever managed before. Lucas was elated!

As he went to the next machine, a persistent prickling on his chest made Lucas stop to scratch. It was as though his body hair had grown in a bit faster than usual, or maybe he just hadn't noticed it before now. But it seemed as though he needed a shave, given the intensity of the itching that was bothering him. Still, there was some excitement in the notion that he was becoming more masculine, somehow, with more body hair, that sat right with him. Not that he was growing more hair in such a short span of time; that notion was absurd. Rather, the mere idea of it seemed to sit right with him, in a way that defied his previous inclinations.

Unbeknownst to Lucas, his armpit hair was indeed multiplying, causing him to scratch there more intently. The hairs already present were elongating, coarse to the touch, while even more soon rose to their place beside them, filling in the gaps and making Lucas itch as he did his reps. The added hair served to trap in more of his sweat, creating a pungent pocket for bacteria to grow. The scent grew in his nostrils, one of a thick musk that overpowered the other odors of the gym. Yet, Lucas was not repulsed by the smell. Rather, it only served as a reminder that he was working on building himself better, stronger. It pushed Lucas through the rest of his set prompting him to strive for height weights and more reps until he was finally, totally, spent.

Hitting the showers, the scent that wafted from his body seemed to elicit a boner that was beyond any he had ever experienced before. His body odor hit him full force in the confined space, yet the stench had him enamored. Never before had the pungent aroma been so...arousing? He felt masculine, powerful, and his stench was indicative of that. For the first time ever, he decided to skip his shower and headed home.

Hunger hit him as soon as he got in the door, an intense pang that seemed more insistent than he recalled in recent memory. Lucas was never one to eat much after working out, finding simply drinking lots of water was generally enough. But, now, not only was he craving one of the steaks in the fridge, but he felt he could eat a whole cow!

Cooking it up, the scent of meat made his stomach grumble even more fiercely, prompting him to pull it from the pan before the meat had reached medium-rare, his usual preference. At this point, the steak was rare, almost to the point of being blue, though Lucas hardly cared in that moment. He was so hungry that he could barely wait until it cooled enough for him to devour it in a few bites! Not quite enough to satisfy him, Lucas contemplated making another one, though thought better of the cost and decided to leave it there.

Getting into the bathroom and pulling off his clothes, Lucas was a little surprised to realize that his shirt had become a little snug. In fact, he had to put his arms up in the air to get the shirt off. At first, he thought it was a consequence of the sweat and lack of shower, but the exposure of his skin made it clear that Lucas was a little bit bigger if that was possible in such a short amount of time. Surely, he hadn't been this big when he'd gone to the gym. His shirt had been a little loose before, but now it was definitely a bit tight, even though the cool evening air did not allow the sweat to stick to him.

His pants, too, even felt snugger, as though he'd added another inch to his waistline. He would have worried he was gaining too much weight, though that should have been impossible with his current build and exercise regimen. A brief glance at his body showed no additional fat, though it was possible that he was bigger if his eyes could be believed. He had half a mind to go and grab some measurement tools though left it to his imagination for now.

Still, before going to bed, Lucas took a moment to admire himself in the mirror. He stared in reverence, feeling rather impressed by the tone that he'd developed. He wasn't sure he looked that way this morning when he glanced at himself before showering, though with the prominence of muscles under the slick skin, it was possible he'd just somehow missed it. In fact, it was the most damn handsome he'd ever looked. His pecs seemed a little firmer, and his usually flat belly seemed a bit harder than last he recalled.

That was not the only thing a little out of place on his frame. His carefully manscaped chest and groin were covered with a light peppering of hair in all the right places. Still, he found the thickened treasure trail, hairy pits, and fuzzy groin were rather fetching on him. Even the scruffy stubble, something he'd never been able to grow before, was as much alluring as it was surprising. Once again, he was certain he shouldn't have this much hair but chalked it up to not paying attention these past few days. Or, maybe it was a product of excess hormone production that caused the growth of his body hair to accelerate. Whatever the reason, Lucas had to say he liked it!

Taking a few moments to really admire his muscle tone, Lucas started to rub his chest and pecs, enjoying the slight scruff that he'd developed. Exploring fingers made it towards his pits, finding what seemed to be the focal point of the additional growth. In some ways, it was almost too thick, out of place on his form in comparison to the rest of it. Moreover, the scent that hit his nose was somehow more pungent than when he had worked out, the sweat left to fester. The odor, however, only served to make him tent a little. It was pungent, musky, and left him desiring a little bit more attention to himself. If only Tyler was home to help him properly enjoy his new body!

Naturally, his hands eventually found their way to his groin, and Lucas could no longer resist the urge to free his member. Pulling down his underwear, a whiff of sweat and musk hit his nose which was somewhat more potent than he was prepared for. Lucas had to admit, he was smelling himself more acutely than he ever had before, though he certainly didn't mind. The manly scents, if anything, were turning him on even more than he could have expected.

The sight of his form and the feelings of elation it gave him made Lucas powerfully erect by this point. Without a boyfriend to help him out, Lucas thought it best to just masturbate there, stroking off at the reflection in the mirror. It helped that his cock seemed plumper than it had in a long time, though it might have just been an effect of the arousal he felt. Still, given the apparent girth of his meat being a little larger than the last time he jerked it himself, Lucas could hardly complain!

A few strokes in and Lucas was already leaking, pre lubing his fingers as he touched himself, not caring to be slow. His other hand groped his balls, feeling how ample with cum they seemed to be and loving the coarse texture of hair that seemed to coat them. Flushed with arousal as he was, it took no time for him to cum, spraying the mirror with thick spunk, the force of which he'd never experienced. And, tired as the workout and orgasm had made him, Lucas didn't even bother to clean up before he went to bed.

His dreams, though fuzzy, seemed to be filled with pleasant images, ones of working out and of musky men and of muscles. At first, it was thoughts of himself with a massively muscled visage he could never support in real life that did it for him. Then, it was his boyfriend, too, just as massive and just as horny, much to Lucas's delight. He imagined bending over the equally built man, taking him, again and again, to spill the lusts in his loins. With each fuck, getting hairier and hairier, their features more angular, almost bestial...

Lucas awoke to the sound of the bedroom door opening and Tyler creeping inside, back home from his night shift. Not noticing the pungent smell in the room, or not caring, at least, Tyler crawled into bed, careful not to wake up his lover. Though Lucas was already awake at this point, Tyler didn't seem to notice, getting himself in a comfortable position.

Lucas looked over at his boyfriend, pondering the situation for a moment. They usually didn't partake in morning 'rituals' when his boyfriend came off the night shift. But, the sight of himself in the mirror last night, and his increased libido made him rethink that prospect a little. Feeling playful, he rolled Tyler over, kissing him passionately on the lips before Tyler could really understand what was going on. Still, Tyler seemed to get in the mood, kissing Lucas back before pulling away.

"Good morning, sweetie," Tyler said, smile on his face. His grin grew when he recognized the lust on his lover's face. Though Tyler was feeling tired, he couldn't help but sport a half-chub, maybe toying with the notion of a little morning fun.

"Good morning to you too, honey," Lucas said, rubbing one hand over Tyler's arms before reaching down under the covers with the other. Brushing it across Tyler's underwear, he gently pulled down the elastic, teasing the oozing cockhead and feeling it twitch at his insistence. Feeling encouraged, Lucas continued to stroke it, hoping to coax his boyfriend into a little morning fun.

"Someone's feeling amorous," Tyler muttered, feeling his erection growing more prominent.

Though tired, the idea that they might indulge was growing in his mind. Even if he couldn't cum, he'd enjoy the touching and attention and figured he would give it a go. Tyler reached out for his boyfriend's face, bringing him in for another tender kiss as Lucas returned the gesture. Lucas was a little smelly, but Tyler didn't mind. It actually made him hornier, an almost primal sense of lust that got him a little harder than he thought himself to manage considering the circumstances.

Lucas, seeing his opening, started making out with his boyfriend with fervor, stroking Tyler's cock in just the way he knew his boyfriend loved. Tyler murmured a little, reaching down at the awkward angle to rub the outline of Lucas's cock through his own underwear. He was a little surprised to find that Lucas wasn't wearing anything but still delighted to feel the head of Lucas's penis against his hand, already leaking and covering Tyler's seeking fingers with sticky goo.

The two of them made out like that for a few minutes, kissing and stroking and even moving into position so that they could frot against each other a little. Still, a little too soon for Tyler's preference, Lucas pulled away, laying on his back and getting comfortable. His cock stood tall and proud before him, eagerly bobbing up and down, demanding attention.

"Want to suck me off, honey?" Lucas asked, feeling a little dominant. Tyler said nothing, just grinning as he got down on his boyfriend's tasty cock. He loved taking that rod in his mouth, even though he didn't think he had the energy to take it all the way this morning. Still, it would be a nice way to have some foreplay, and maybe it would bring him close enough that they could gently stroke each other off to completion before going to bed snuggled in each other's arms.

Taking the thick rod in his hands, Tyler opened up his mouth, licking the leaking tip and tasting Lucas's precum before going down on the head with the caress of an experienced partner. He loved tasting Lucas's cock, after all, it was something they partook in on several occasions a week if their schedules lined up. He eventually went further down on it, taking it back towards his throat before pumping up and down with more enthusiasm than he figured he could manage after a rough evening lifting boxes and crates.

Still, Tyler was determined to go down on Lucas as best as he could, trying to find the most comfortable position that could make him last longer. He felt his lover's cock expand in his mouth but still did his best to go at it before fatigue had his jaw tire. Lucas, moaning a little, was clearly happy with the attention, petting Tyler's head as he went at it.

Wanting to tease his lover as best he could, Tyler reached out to stroke his boyfriend's balls, the coarse hairs above them seemingly thicker than they had been the last time he had played with him days prior. Though Lucas sometimes let his manscaping go by the wayside, it couldn't have possibly grown so much in such a short period of time. Still, there was something exciting to its presence, the masculine assets spurring on his exploration rather than turning him off. What other things would he learn about his love if he teased further?

Like his groin, his love's testicles were coated in luscious hair, though it was a little softer than Tyler had been expecting. It was pleasant along his touch, making him stroke the skin gently, the wrinkling flesh a wonderland of sensation. A moan and grunt from his lover were all Tyler needed to know that his efforts were being appreciated and that he should go for broke.

To Tyler's surprise, the cock in his mouth seemed to engorge further if such things were possible. It was as though the erectile tissue was becoming impossibly erect, almost enough to harm Tyler's mouth. He could tell his lover was close from the intense throbbing and wanted to be good to his love. It wouldn't be long now if he could just keep it up...

Lucas, meanwhile, was in heaven, the pleasure emanating from his dick more than anything he had ever known. It was as though the sensitivity of his member had been dialed up to an eleven, making it impossible for him to hold out for long. He could see that his lover was straining and gently put his hand on Tyler's head, encouraging him to continue at a slow and steady pace that was sure to bring him release at any moment.

"Oh fuck babe, can't hold it...gonna blow...fuck so good...oh fuck, I love you!" Lucas cried out as his balls throbbed and his penis spasmed, sending him into orgasm. More sperm than he had ever ejected before spewed from his member, sent almost forcefully down Tyler's gullet. He had to pull back a little, drool and cum leaking from his lips as he looked up at his lover before getting a wad in his face. The sensation left both men giggling in a way that only lovers could know, the act of making love more eventful than any time in recent memory.

Tyler was inclined to go get washed up, not comfortable with swallowing and needing to wash his face. Lucas, however, awash in his sweaty musk and the aroma of cum, immediately passed out, sated and tired beyond belief. Though he normally liked the scents of their soap, there was something compelling about his natural musk that had him falling asleep as soon as his head hit the pillow.

Be it the amazing sex or the stimulation of having a good workout, Lucas's dreams were once more filled with vivid images, ones of muscled men and their musky scents. His cock was hard even after the incredible blowjob he'd received and had even shot a thick load onto their sheets as he slept. Tyler accidentally put his hand in it as he snuggled into his boyfriend, a little grossed out until he realized what it was he was feeling. It wasn't that bad, all things considered.

The thick scents of stale sweat caused Lucas to arise slowly, content with his cock at half-mast. Lying there for a few moments, gently stroking his rod as he checked his phone, Lucas started to feel more awake than at any time in his life. Though Lucas usually took a day off from the gym to rest, instead of being tired, Lucas felt invigorated, easily able to do all of his regiment again. The excitement of pushing himself won out, and he got up with the intent to hit the gym. The only disappointment was that his boyfriend was working nights this week and couldn't join him. It would be exciting to challenge each other before another amazing romp in the bedroom. Lucas wasn't sure where he was getting so much stamina, but he certainly wasn't complaining!

Lucas worked from home, and although his mind was fixated on his workout to come, he was able to get a decent amount of work done before his love awoke. Lucas already had the coffee on for his boyfriend before he could hear him getting out of bed. "Morning, Babe," Lucas said, and Tyler nodded before giving his boyfriend a double-take. Not that he minded seeing his lover naked, but he wasn't expecting he'd be working in the buff!

Stranger still was that Lucas didn't seem bothered by his state of dress. He smiled up at his boyfriend, only the concerned looked in the other man's eyes giving him confusion. "You good, babe?" Lucas asked, and Tyler nodded, figuring it wasn't worth the hassle. Instead, he got his coffee before thinking it prudent to further check out his lover's erection sticking out from under his work table. Damn, it was only at half-mast, but he was sure that his lover was a little longer than last he saw it clearly. And that whole thing had been in his mouth!

Giving his boyfriend another once over seemed to make Lucas spring to life at full attention. The sight made Tyler curious, but he had very little gas in the tank for such fun. Still, if only...

Yet, the more he stared at his lover's nude form, the more Tyler had to say he was impressed. There was more hair than there should have been, a rather manly coat covering not only his groin but spreading up in a black treasure trail that Tyler wanted to rub his fingers through it. His beard, too, was more scraggly, though he was sure he had seen Lucas shaving it a few nights ago. This was more like a week's worth of growth! Not that he was complaining, but...

"Like what you see, honey?" Lucas commented, making Tyler blush a little. He hadn't wanted to stare, but Lucas seemed insistent. Though the two of them generally switched when it came to bedroom affairs, Tyler loved it when his boyfriend took charge, enjoying the notion of being dominated and commanded a little. And lately, Lucas had been all man with his domination.

"Damn, honey, you look good! I was worried you weren't catching up!" Tyler said, really taking in his boyfriend's naked body. He had to say that the effects of weightlifting had escaped him in recent weeks. Hell, Tyler almost swore that his love was a different man, though the facial features were evidence to the contrary. Surely, he was imagining things one way or the other.

Eventually, Tyler had to leave for work, surprised that Lucas was planning to go to the gym that night. Not that he needed it, Tyler thought, though he wasn't complaining about the results. In order to help out his lover, Tyler made him another shake the same way as the previous night, one that Lucas drank greedily. It seemed to spur another surge of arousal through his loins, once more making Tyler blush. His only detriment was that he didn't seem to have the sexual stamina that his love did. Still, he was more than happy to help out his lover whenever the other man asked. Hell, maybe he should try the new protein drink next time he had a night off to hit the gym with his love!

"See you in the morning, sweetie!" Tyler said, giving his naked man a kiss before heading out. Tired as he was, there was a level of arousal that seeing his lover naked made him feel.

Lucas, meanwhile, considered having a shower before dismissing the thought. He threw on his clothes from the previous night for his trek to the gym. To his surprise, they seemed to be pulled even tighter on his frame than before, though there was the additional benefit of showing off the tone that Lucas had put on over the course of the last few weeks, and especially last night. He even got a few looks from both men and women as he walked out of the locker room at the gym.

Though no one seemed to notice his musky stench, being in a gym, Lucas was in heaven with the scents wafting off his clothes. They spoke of his exertion, his work to improve himself, and all he had gained. Better yet, he smelled of male, the essence of power, testosterone, and muscle that made his cock bob in his shorts. He was almost painfully erect, his penis outline showing through the fabric of his stretched shorts and turning more than a few heads. Though Lucas felt pride in that, able to tell they were jealous by something in the air.

At that realization, Lucas noticed certain intricacies of the odors that were difficult to pick up but still present. Scents like confusion, pride, jealousy, emotions, in general, were made aware to him when such things had no name before now. They were minute traces, not something he'd be able to detect out in the world, he was confident. But here, in proximity to so much sweat and musk, were details that only someone like him could notice. It was almost overwhelming! Still, in the presence of his own scent, Lucas decided to leave them to the wayside and focus on himself. After all, his health and vitality were higher than anyone he could smell, all that mattered to him!

As last night, his normal workout was far too tame for the strength that he seemed to possess. His strong arms pulled the heavy weights, lifting the bars and completing his reps with ease. It was like they were featherweights to him, and even going beyond his possible limits was made more effortless as the night went on. Without his boyfriend to spot for him, Lucas maintained the sense not to overdo things. But, he couldn't wait to have his lover join him, not only to show off but to see if the protein shake had the same effect on Tyler!

The more he lifted, the more that Lucas couldn't deny the power flowing through his veins, an electric tingle that made him feel more alive than at any previous point. Even the higher weights proved like a mountain that he had just enough energy to climb, building the power in his form and making him growl his determination. The sounds coming from his lips radiated more strength than anything he had ever been able to muster. That, and the bestial quality they seemed to possess made Lucas's cock rise just enough to make the bulge noticeable.

The only thing that could even remotely deter him from further reps was the persistent itching playing over his chest. He took a few moments to rub the skin, the hairs thicker than even the last time he had noticed, like fast-growing weeds. More than that, there seemed to be hairs peppering the expanse of skin beyond his belly and chest, even connecting with the ample bush of his armpits. Rather than being deterred by the excess smell that the hairs seemed to draw in, Lucas breathed them in headily, drinking down the male musk with enthusiasm as though sampling his male assets.

As he lifted and pulled and ran his laps, Lucas could feel that his clothes were getting tighter, to the point that he feared he would break from them if he strained too much. It was as though even his simple workout had swollen his body slightly. They were just taut enough so that getting them off in one piece would be impossible. Still, the notion of being naked, exposed, was more powerful an attractant than anything Lucas could recall from recent memory. He didn't mind that his efforts were bringing them to the brink of destruction, wondering as though it was a game whether or not his clothes would last.

To his delight, the sound of fabric tearing hit his ears at the same time the warm air of the gym hit his cock. It was almost freeing as his penis hit the air, spearing for the hole as it poked through and exposed itself for all to see. But instead of trying to hide his junk, Lucas only grinned broadly, not ashamed of the nudity or that he was on display. They should be so jealous to own such a cock or have their lover sport one!

Still, the muffled complaints eventually prompted Lucas to enter the locker room, not bothering to change as he grabbed his stuff and headed home. He couldn't help but feel pride in his maleness, and the clear scents of jealousy he detected wafting off their forms spurred on that notion. He was clearly the biggest man in the gym, the physical envy of all present. It was pure elation!

Heading out into the cool evening, Lucas wasn't even prompted to put on his jacket, overheated from his workout. His bare state drew the expected stares, but, like in the gym, Lucas paid it little mind beyond being flattered by the attention. He didn't even bother to cover the hole in his shorts, though his cock did not rise to erection in the chilly air, and the split could really only be seen if someone stopped to stare.

Though Lucas was sure the scents he encountered in the locker room were amplified by his proximity to them, similar odors were present in the air outside. He was sure they were ones his nose couldn't have detected before tonight, he was sure. It was like the world was full of little notes of information that had somewhat escaped the fringes of his mind before now. But now, aware as he seemed to be, Lucas could detect nuances in the scents that he picked up off others that he simply passed by. Things like age, health, what meals they'd eaten, the last time they showered, and other little things were at the forefront of his thoughts as he breathed in the scents of the city and its inhabitants with a potency that usually evaded him.

It was more than just the smells that piqued Lucas's interest as he passed the busy streets toward his apartment. It was as though the world was alive with sound, his ability to hear having evidently been dialed up. It was no trouble to detect others' conversations even through his earphones. In fact, it almost felt that his ears were moving of their own accord, though in the night air Lucas just thought them to be numb.

To Lucas's interest, it seemed as though the sights and sounds elicited excitement that defied his understanding. Knowing where everyone was, their moods, their voices, their...well, everything made him more curious than Lucas had ever felt. The world around him held more interest than the podcast he was trying in vain to pay attention to. It was akin to wishing to be dominant in his domain. As strange as it sounded to think those words specifically, Lucas thought it suited him right as he headed home for the evening.

The more Lucas focused on the sounds and sights of the world around him, the more that certain other intricacies held his interest. People were present, sure. But there were animals, dogs, cats, raccoons, squirrels, and a myriad of other creatures that Lucas had to reflect on before realizing what they were. Better still, his apartment street sat near a patch of woods, and the scents and sounds removed from the urban setting were more appealing to his current sensibilities than anything else. Well, save for his own muscled visage, of course...

Yet, there was a desire to self-indulge in the latest fruits of his labor that overrode the sense of adventure that made him see the world in a new light. He knew he was bigger, hairier, and that his gym regiment was giving him the body that he'd always admired but never thought in a million years could be his. It was powerfully exciting to see himself in the mirror, to give his body a good rub down!

Taking off his clothes was a precarious affair, one that Lucas soon decided to end by tearing them off with the muscle he now possessed. He was never going to be that small again regardless, Lucas was certain. Not if he kept drinking that wonderful shake and performing his gym regimen! Besides, the shirt was really irritating his body hair, and, with the body he was developing, it would do the world better to see him in all his glory!

Thinking it would take some effort to get the restrictive garments off, Lucas was pleasantly surprised to see that his nails seemed sharper, pointed on the ends of the thickened keratin. A bit of discoloration made him perplexed, though he figured he must have stained them with something during his workout. Still, digging the nails into the holes in the fabric made it easy to expand the tears, the sound music to his ears. There was something elating in tearing off the weakened clothes to rid himself of his older life when he was smaller, less of a man than he currently found himself.

Staring back was a visage that didn't match the man he had been even the night before. He could still see something of himself in the reflection, something in the eyes that made him aware that it was himself. But his body hair, his muscle tone, hell, even his jawline seemed to belong to some other man. Lucas knew he had to be imagining things, tired as he was from the workout. There was no way he had put on so much muscle and mass in such a short period of time. Yet, there was no denying how much he loved the results!

Still, there were hints of differences in his facial features that made Lucas a little curious rather than concerned. His ears seemed larger, for example, as though he was wearing some sort of elven prosthetics or the like. And as he reached up to touch them, his fingers reported the skin was warm, and they even twitched a little as he rubbed them. It did explain the numbness and their enhanced auditory abilities, something that Lucas ultimately relished over any concern over their alterations.

There were other, slightly noticeable differences to his features that had Lucas squinting in the mirror to try to place them. Before tonight, he was certain that his eyes were the same dark brown as they had always been. But now, given their slightly lighter color, closer to a golden hue, he wasn't sure if he was still looking at his own eyes. They looked like the eyes of a stranger if such was an apt term. Lucas could still hardly believe that it was his face he was looking at!

Jawline thicker, more angular, Lucas lowered his hands to rub along it when the sight of his canine teeth gave him pause. It seemed they were longer, more pointed, though he at first chalked it up to a trick of the light. But, opening his mouth revealed a more predatory grin than what Lucas recalled from smiling. His teeth were sharper, the edges pointed, serrated, and looking a little out of place. But, in tandem with the changes to his head and the additional hair, the beastly appearance was rather fetching, with an undeniable sexiness that had him elated.

The hair atop his head was longer, shaggy as though he had gone a month or two without getting it cut. Running his large hands through it detached a coarse texture through all the sweat of his unwashed body. It ran down in sideburns that matched the thickened beard that had sprouted across his chin, cheeks, and upper lip. It was bushy and a little unruly, though rather fetching. And his body hair was ample, running down his chest like a bear pelt. His chest and treasure trail were as thick as a pelt, and dark hairs peppered the sides of his chest down to his groin. He was sure he sported a mighty bush down there as well, though decided to take his time, admiring his upper body before his lower half was enjoyed to the fullest.

Best yet were his hairy pits, the bush sticking out from underneath like something from an untamed beast. The pungent smell of musk wafted off each in droves, and Lucas raised them higher, sniffing his male essence and all the intricate odors that came with it. The powerful stench made his cock ache, coming through the hole in his shorts and making the altering man moan from the exposure. It was all he could do not to stroke himself off right there, the reek of male redolence deep in his nose and making him boned as hell!

Reaching out with a curious tongue, Lucas sampled the sweaty essence of his underarms, that salty, stinky fluid making his mouth salivate. It was like he couldn't get enough as he sniffed and lapped his fluids, drooling and coating his armpits even more. The smells were divine, their nuances more detailed than anything Lucas had detected before. They spoke of his power, the gym visits, and other things he had no name for. But, it was clear that he needed more!

Musk-drunk as he was, it took Lucas a little while to come up for air, as it were. He was hard as hell, his boner pushing even more at the stitches of his gym shorts. It was thicker than its formerly cut self, bobbing up and down against his legs. His swollen testicles seemed a little fuller, too, if that were possible. It was like he hadn't cum in several weeks, though he knew full well that he had gotten his rocks off several times yesterday.

Sharpened claws reach down to do away with his shorts in short order, tearing them away and exposing his rock-hard erection. The size was something to behold, surely bigger than he had ever been possible. Though it was difficult to say given the heightened arousal that he had been experiencing over the last few days. The shaft itself seemed a little red, as though it had been rubbed a little too hard. Yet, the flesh seemed no worse for wear. Stranger still, his foreskin seemed to peel back a little further than before, like it could take more of his cock inside of it if he was in a flaccid state. Though, given his current feelings of lust towards the alterations thus far, Lucas could be excused for not being able to keep it down when he had such a manly body to enjoy!

There were more alterations to his groin that left Lucas momentarily confused, though less so when taking into account the more manly physique that he now possessed. As he'd envisioned, his groin was a thick forest of dark, sweaty hair. But, the light coat of black hair peppering his foreskin was unexpected, especially the rather soft texture that greeted his touch. And it was so thick on parts that Lucas could barely see the skin in some places. Still, all in all, the look of his groin made Lucas flush with even more arousal...

Before masturbating, Lucas took off his socks and shoes, not wanting them to get in the way of his body being entirely naked. The idea of jerking himself off to his nude form was a powerful attractant to the altered man. Though his shoes felt a little tight, his socks were of no use to him as he tried to take them off with a loud tearing sound. The nails at the ends of each were pointed, sharp much like the nails on his fingers. In some ways, his feet were even worse off than his hands, the undersides coarse and rough with a shade of skin darker than his own, as though bruised.

Still, Lucas didn't mind too much and carried on with his rather impressive member. The size of his girth was clearly different than anything he could have previously fathomed on his form, though at the moment, Lucas could have cared less if it was the phallus of some animal. In fact, the increasingly red shade over his penis was less reminiscent than one sported by a human being. That notion only made him more erect, excited at owning something so manly, so large, so needy.

There was little in the way of holding back as Lucas felt his balls churn as his cock went into overdrive. What started as the usual level of orgasm soon intensified beyond levels Lucas was able to cope with. His vision was whiting out, stars flooding his eyes as he came, cockhead erupting with several thick blasts of jism onto the bathroom sink. The scent reeked of him, of his maleness, and only served to spur on further thick blasts of semen. It was a load larger than anything he could recall shooting, more jism buzzing through his penis than what he figured even his balls could produce. Though there might have been significant bias, given his enhanced senses and the level of pleasure he took in his newfound masculinity. Either way, Lucas was in heaven!

Yet, staring into the mirror, Lucas noticed two things that made his mind fog over. The glint in his eyes was more pronounced, brighter, if that was possible. It was as though the dull brown had lit up with accents of amber, shining slightly as he looked from side to side. All in all, it seemed to accent the bestial features that his face seemed to sport.

The other thing was that the glow of the moon reflected from the bathroom window was visible if he looked from a certain angle. The sight of it seemed more entrancing than at any time he recalled. It sat in the sky like some sort of beacon, raising the elation that Lucas had already experienced from his previous outing. Overcome with the desire to see it more closely, Lucas stepped out of his bathroom and headed out into the night, his naked state hardly a deterrent. His body felt warm enough with the added hair and his newfound energy that the cold did not bother him. There was no one around at this late hour, Lucas could smell as much, though anyone's presence would hardly deter Lucas's lack of care towards his nudity. Something sat well with his proclivities about being out in the world in his birthday suit.

Forest nearby, Lucas took off running, determined to submerge himself in the call of nature and the moon that seemed to beckon him. Though he was naked, his feet were not pained by the efforts, his soles having grown coarse enough that even rocks and pebbles caused him no discomfort. Even sticks and branches did little to hinder his run, the extra hair on his body a deterrent to any scratches. Any cuts and bruises were soon erased as though his skin was able to rapidly close the wounds and prevent further injury.

All of that was ignored, however, with the elation he felt at the moment. Lucas couldn't figure out the last time he'd felt so invigorated. It was pure rapture to experience the forest all around him, a sensory overload accelerating him beyond human comprehension. Lucas was along for the ride, allowing his body to function on autopilot. He wasn't exactly sure what his destination was, but he was all too eager to explore these new urges to their eventual conclusion. It was like a new side of himself, one he was eager to explore and experience in the here and now.

Eventually, he came to a clearing, the moon illuminating the ground like a spotlight. Lucas was compelled to step into the center, staring up at the luminous orb with a sense of reverence. It was as though it was shining just for him, to fill him with energy, almost a purpose beyond reasoning. It was as though all his workouts, all his efforts were leading to this moment when he could stare up at the moon and thank it for all it had granted him.

There was only one thing left to do. "YYEEAAAAAOOOOOOWWWWW!!!" Lucas yelled at the top of his lungs, singing his praises to the beautiful moon and all the night had to offer.

The sudden surge of energy left him hard as hell, and despite having cum not even an hour ago, he felt the need to jack himself off, to spill his beastly essence all over the forest floor. And so he did, feeling the soft hairs of his deeper foreskin pulled away to reveal a reddening member that almost glowed in the light of the moon. Precum glistening, Lucas began to drool, salivating at the sights and scents of his lust. His leaking rod lubed up coarse fingers, thicker skin at the tips seeming to grip him even better than before. It took him no time to shoot several thick wads of semen into the air, landing on the ground and filling his nose with the musky scent of release. It seemed to mark his place under the moon, in these woods that lacked the oppressive human scents of the city

After that, the rest of the night seemed to pass like a blur. Images of running, of hunting, of stalking, came to the forefront of his thoughts. Though he did not eat, did not kill. Raw meat was tempting, and he was on the cusp of eating it himself. Still, the thrill of the hunt evoked something inside of him that could not be denied. It was like he was running in a dream, a muscled, bestial being beyond his wildest imaginings.

Though, eventually, as the first fringes of dawn began to creep into his sight, Lucas felt his energy starting to wane enough that he made his way back. Not caring that anyone saw him, he entered his apartment, his body still covered with sweat and bits of branches and leaves caught in his hair. But after a night of running, the fatigue had caught up to him to the point of needing to pass out. Dreams of his night and all that it promised lulled him into unconsciousness...

******

The next morning, Lucas was roused from sleep by a loud gasp from his boyfriend. "Hun, did you shower after working out? It's rank in here!" Tyler exclaimed with a tone that normally would have made Lucas embarrassed. Instead, the odor permeating the room made him horny as hell, leaving him unable to muster any shame from it. It was the odor of success, of power. It was the odor of male.

Memories of the night before came to the forefront of his thoughts as he went to sit up. Lucas was sure they were simply dreams of running through the woods, sniffing, and hunting. Yet, the images were so vivid, so powerful it was almost impossible to deny that they might have actually happened. Even the smell of woods, the feeling of dirt on his body, led credence to the fact that he might have been up to some forgotten moonlight escapades.

Still, he woke up quickly, the thick musk bringing him out of his dreams into the present and a sudden sense of excitement. Lewd notions flooded his psyche and gave him a fantasy far better than any dream. Feeling harder than even his morning wood should account for, Lucas got up, staring Tyler in the face with a lusty grin. "Smells good to me, honey. Why don't you get over here and take a closer whiff?"

Though it was dark, Tyler had a hard time seeing his boyfriend in the man silhouetted in the morning light. If it wasn't for his voice, Tyler might have thought it was another man. Lucas seemed larger, more filled out than even he had appeared yesterday. It should have been impossible for the man to appear in such a state, even after months of diligent gym visits. And the smell in the room...

Yet, the more Tyler breathed in the potent male musk, the more his own boner started to tent his underwear. He seldom had an interest in bedroom affairs after working a night shift, much less after the fun they had the night prior. But, damn if the sight of Lucas's erection didn't do it for him. Even in the low light of the room, there seemed to be something off about it that made him confused. Lucas's foreskin wasn't normally so pronounced, right? Still, it was dark in the room; maybe his eyes were simply playing tricks on him. And the odor in the room was making it harder to think...

Before he knew what was happening, Lucas was on him, taking him in a passionate embrace and pulling him toward his sweaty, hairy body. The sensations didn't feel right; the two made love often, and Tyler was very familiar with his boyfriend's body. Muscle size, body hair, and even the girth of his cock didn't match what Tyler was accustomed with. Even the changes from the day before couldn't quite account for the level of alteration that had enveloped his lover. But, the skill at which his love played over his body made Tyler sure it was Lucas. No other man had ever known him in such a way, exactly how to please him and their practiced sexual encounters. And, with the musk in the room, it was hard to tell how much his mind was imagining the level of alterations his lover was experiencing.

Eventually, Lucas pulled back, looking over his work as Tyler stood there, dizzy from the raw animalistic essence of his boyfriend's scent. Lucas seemed rather pleased that Tyler was so enraptured with the smell. His inclinations told him to take what he wanted from his willing lover, even if Tyler initially found the intrusion confusing. Tyler was surely into whatever he had planned, even though there was a note of hesitance in his demeanor.

Tyler was surprised to feel himself being pulled lower by the stronger man, not inward to further their make-out session. His nose was pressed tightly against Lucas's nipples, and instinctively, his tongue reached out, lapping reflexively as their play had sometimes brought them to. Yet, soon, his head was pulled further towards the underarm, tongue trailing across pecs that were meatier and hairier than Tyler recalled Lucas having. Still, Tyler was swept up in the moment, and willing to do whatever it was that his boyfriend requested of him. It was his sexual pleasure to do so, after all!

Not expecting to stop at the thick hairs that lined Lucas's sweaty pits, Tyler almost gagged, the salty BO overwhelming his senses. It wasn't just the taste that his tongue played over, but the raw animalistic odor that was powerfully redolent. Tyler squirmed a little, wanting to pull away and breathe, though fresh air in the room was hardly present. Yet, against his expectations, Lucas held him down, forcing him to breathe in the sweaty stink without any chance of escape. Tyler wanted to struggle, to call out that it was too much. But the longer he stayed there, forced to lap at the ample body hair and all the manly odors that came with it, the more that the dizzying stench made it harder to think. It was all he could do to keep himself cognizant, much less try to escape. He could only lap at his lover's hairy pits, growing more and more accustomed to their overwhelming presence on his nose and tongue.

Lucas, for his part, loved when his boyfriend stopped struggling and licked his male essence. He was in control of their sexual encounter, and something in his changed sensibilities made that seem right. It was his right to subject his beta to his whims and have Tyler do whatever he commanded. Wait, beta? The term came with it a hint of confusion, but, in the end, he decided that it was fine and his right to do.

Even over the heavy musk of his body odor and sweat, his throbbing cock added its own pungent stink to the mix, leaking down the shaft and all over his hairy groin. Though it was a powerful aphrodisiac to control Tyler like this, the needs in his cock were getting insistent, and he couldn't hold onto the simple body worship without giving his lover a good fuck.

"Bend over, babe," Lucas growled, finally allowing Tyler the chance to breathe. Tyler was still dizzy from the intoxicating stench, though did as he was told, getting into a doggy-style position and pulling back his buttcheeks to allow his love to apply the lube. The two of them often switched, but in this instance, Tyler was inclined to be on the bottom, to allow his dominant lover to take him.

Expecting the cool sensation of the lubricant, Tyler was not prepared for the warmth of his lover's cock on his rectum, rubbing around the rim and teasing the inside of Tyler's fuck hole. Though it should have been impossible that precum alone would be enough to spur on their lovemaking, the sheer amount that his love was leaking seemed to contradict that. It took almost no time for Lucas to leak enough that he thought Tyler prepared to take his rod.

A gasp escaped Tyler's lips as a cock far thicker than anything he had taken in his life was inserted into his rear. It was almost too much, opening him almost painfully as Lucas pushed inside with insistence. It was as though he cared little for Tyler's comfort, taking him with only the desire to meet his own needs. And still, given the state of his mentality and the pleasurable sensation in his bowels, Tyler felt his own cock throb with the notion that he was being taken, dominated in a way that suited his new sensibilities just fine. Even the strange sensation of extra skin rubbing against his pucker and the odd tip of the shaft were ignored in their frantic lovemaking.

More akin to a beast than a man, Lucas fucked faster and more insistently than ever before. It was as though he saw his love as more of a fuck toy than his boyfriend, and his forceful breeding was indicative of that. Moreover, he needed to rut like that. Each thrust corresponded to a tingle in his muscles that felt akin to the splendors of working out. Muscles were tearing and reforming, tissues repairing with little effort. The sensations were almost erotic on their own, as though Lucas's sexual exploits were spurring on the muscles that longed to ripple through his form.

Better yet was the intense itching all over, as though the very hair follicles were thickening. Though he sported a sizable treasure trail already, it seemed to be even longer than that at this juncture, even covering his formerly bare sides, running like a pelt down from the thick bush of his underarms. It made it hard to see the skin in some places, though, in the relatively dark room, neither man could tell the difference even as what seemed like shadows crawled over parts of Lucas's body.

Thicker hairs were not the only change to overtake Lucas's body as his teeth started to ache slightly, as though he'd visited the dentist without any anesthetic. Reminded of the pointed canines he'd noticed last night, the ache was still intense enough to account for further growth. Soon, his entire jaw was sore, gums almost bleeding with their effort to make room for sharper dentures. His ears, too, felt slightly off, as though overheated and shifting up the sides of his head. But, ass deep in his lover as he was, the changes were only a slight inconvenience as he continued to rut and prepared to release his semen.

Tyler could only moan, the force of the orgasm more than he could bear. Though it was no longer painful, the notion of being taken in such a way was more than his mind and body could hold out against. He cried out as his cock went into orgasm, spilling his cum onto the bed and gripping onto his boyfriend as Lucas, too, unleashed his load into Tyler's rear. A euphoric bestial growl escaped Lucas's lips as he did so, making both men shiver in release and satisfaction.

Without fanfare, Lucas pulled out of his lover, leaving his fluids leaking from Tyler's ass. Tyler wanted to get up and clean himself off, but the pungent scent of musk and the release he felt made it impossible for him to muster the energy to do so. Passing out, his snores did not distract Lucas from a growing part of him that did not want his semen to go to waste. Lowering himself with inhuman flexibility, Lucas reached out with his tongue, lapping at his cock and body to clean the cum from his form. He relished in the salty, heady taste of his potent seed before laying down beside his love and holding him close.

Tyler awoke sometime in the late afternoon, the stench of their sex and Lucas's body odor still permeating the room. It took him a few moments to get his bearings, realizing that he was alone in the bedroom. Getting up and putting on some clothes, he was shocked to find the heady stench of body odor not only leaking from the room but filling the entire apartment. He knew it should have perturbed him more, but at the same time, he'd grown accustomed to the stench by this point and paid it little mind. Its presence made it more difficult to think of why it bothered him so much in the first place, anyways.

Musk drunk as he was, Tyler was not expecting to walk into the kitchen to find his lover naked, cooking up a couple of steaks with the look of a ravenous beast in his eyes. Not even waiting to put them on a plate, Lucas tore into one, his new, sharper teeth ripping into the barely cooled flesh. Soon, one steak was devoured, then the other, before Lucas noticed that Tyler had awoken.

"Morning, babe," Lucas said, licking his lips as though what he'd done was the most normal thing in the world.

Tyler found himself doing a double-take. Normally, his lover naked was a sight of celebration. Certainly with the level of fun they'd been having the past few days. But, in the clear light of the kitchen, Tyler had a hard time rationalizing what he was seeing. Lucas had the curtains pulled back; anyone who walked by their apartment could easily see him through the window. Though Lucas didn't seem to mind, Tyler was prompted to close the curtains, though at the moment was more interested in keeping the sight of his love for himself rather than telling Lucas to put on clothes.

Examining Lucas's naked body more closely, Tyler found it somewhat puzzling to behold. Lucas was clearly larger and taller, his dimensions not matching the boyfriend he'd had even the day before. He had grown a few inches and put on at least 50 pounds of muscle, if not more, and the muscles filled out his form more than Tyler could have ever imagined. Yet it was impossible to deny it was clearly Lucas, after all. Maybe he just hadn't noticed the changes before now?

No, that couldn't be it, his half-asleep mind reasoned. There were other, subtler changes that made Tyler more than a little concerned. He knew instinctively that his eyes were playing tricks on him, that it had to be the man that he loved. Maybe fatigue was doing him in. Still, it appeared to him that even his lover's face was not the one he was so familiar with. His jawline was larger, teeth sharper, and ears pointed out of a shaggy mop of hair. And, his naked body was covered in hair, beyond what even a bear of a man would envy. It was dark, almost fuzzy in some places. Hell, it was hard to tell that he wasn't wearing some kind of shaggy coat!

Lucas, for his part, did not seem the least perturbed at the sight of his eager lover's confusion. Turning around and grinning at the attention, Lucas locked eyes with his love. Tyler was not expecting to see his boyfriend's cock at half-mast, leaking pre from the simple sight of Tyler being in the room with him. Seemingly without thinking, Lucas started stroking his cock, bringing himself to greater arousal than Tyler had ever seen. The sight of Lucas's erection seemed longer than his average 6-inches, though it was hard to be sure without measuring it. And the sight of it...the red shaft, the thick, hairy foreskin, and the pointed tip...that wasn't a man's cock!

Yet, the heady stench in the room from his man's precum and sweat made him dizzy, and Tyler sat down, trying to rationalize what he was seeing. It should have been impossible for such alterations to exist on a man. They couldn't be what he was really perceiving. He must have been imagining things, Tyler's mind seemed to settle on. It was amazing the human mind's capacity for self-manipulation, and, in the moment, Tyler could think of no other reason for the bizarre alterations to his lover.

Lucas, for his part, acted like the whole thing made up their regular afternoon ritual. His confidence and showmanship were nothing like the man that Tyler had fallen in love with. But...this was still Lucas, right? It was clear the gym had been working out well for his lover, whatever his mind perceived about what was happening to him. And Lucas seemed to carry it well, given his nudity and confidence. Tyler loved his man dearly, but now his lust for the man had grown ten-fold, to the point that it was hard to think about anything else.

Getting closer to his man, and inhaling the musk, a grin crept over his face as he stared into the jock of his dreams. "I take it you like how the drink is working?" Lucas said, kissing his boyfriend before nuzzling Tyler's chin with his thicker beard. Though it was impossible for any drink to do this to someone, it seemed to be the case if what he saw before his eyes was to be believed. And, Tyler could will away the other alterations, citing fatigue as their source. Right?

"GRRRR...You certainly picked the best one, my RRRove..." Lucas said, growling his contentment at their close contact. His voice seemed heavy to his own, twitching ears, though hardly cared in the moment, kissing the other man back.

For his part, the sound of Lucas's voice intrigued Tyler. It seemed slightly off, as though deeper, more growly. Yet, it was a dominating sort of tone that awakened something in him, something submissive and needy. He eagerly allowed his boyfriend to grind against his body, that leaking cock running down his legs and bringing his own cock to attention. Despite their frequent love-making sessions as of late, Tyler couldn't deny how much the odor was doing it for him.

Tyler hardly had any time before he needed to shower and get ready for work. Yet, he couldn't help but get down on his knees and service his boyfriend the way that Lucas seemed to demand. Lucas was keen to allow Tyler to do his work, rimming Lucas's cockhead and drinking down the ample pre leaking from it. Yet, the needs to dominate and take what he wanted soon came to the forefront of his thoughts. Once more, any notions of romance were thrown out the window for the desires that were playing over his mind. He would make his beta service him, and knew his beta would do so willingly!

Suddenly, Lucas grabbed his lover's hair, pushing him forcefully onto his cock all the way. Surpassing the urge to gag, Tyler still diligently sucked, the thick body odor from his love wafting into his nose and edging him on. The sight of an unattended overgrown forest when he knew that his boyfriend was cleanshaven before surprised Tyler somewhat, even after giving his over a once-over before. Opening his eyes wider, Tyler was sure that he could see the hairs lancing outward before him, growing out of pores and coating the skin in odd places. If Tyler didn't know any better, he would assume that his lover had developed a coat of fur or the like! Yet, the more the hairs grew, the more the sweaty stink seemed to trap within them and burn into his nostrils, making him close his eyes to revel in the musk.

That was hardly the only sensation that seemed out of place during their activities. There was no escaping the sensation of the dick he was bobbing up and down on getting longer, thickening in his mouth, and stretching him wider than Tyler thought he could manage. Though, whether it be his lust for the man he loved or the idea that he was taking a cock the size of his deepest fantasies, Tyler was diligent to drink down the load that his love had in store for him.

Given the lust that his boyfriend seemed to exude, Tyler did not have to wait long for what was coming. The dick he was deepthroating seemed to be closer to 8 inches now, and thicker than humanly possible. Tyler slid up and down the pole without gagging, even as he was forced to speed up by his eager dom thrusting into him. Even the nails that were getting slightly sharper against his hair were not enough to deter him as he reached down to tease Lucas's balls, feeling a noticeable difference in size, though it was hard to focus on such things in his excitement.

When Lucas finally came, the sheer force of the orgasm nearly made Tyler pull off his cock. But, Lucas held on tight to his lover's head, making Tyler suck down every ounce of rank, thick fluid that Lucas had to offer. Tyler nearly gagged from the sheer quantity, but, somehow, he managed, through sheer force of will from his lover's insistence. It was as though Lucas's needs were burning into Tyler's psyche as well. Tyler couldn't think of anything he needed more than to please the dom that had chosen him to meet his lusts. It spoke to his deepest fantasies, and now that they were somehow coming to life he would be remiss for not falling into them completely.

Tyler moved in to snuggle his boyfriend, noticing for the first time that Lucas seemed surprisingly taller. The two men were formerly similar in height, though now, Lucas seemed to have gained a few inches, prompting Tyler to raise up slightly to kiss him. Still, the difference in height went largely unnoticed, even as Tyler rubbed against Lucas's bushy beard and thicker chest and body hair. It was as though the sex and taste of musk and cum were clouding his mind, making him certain that all was right, despite what his better judgment should have been telling him.

Eagerly, Tyler continued rubbing the ample body hair that seemed to still be prickling the surface of Lucas's skin. He traced his hands over it, loving the tone underneath and the coarse, grizzled feeling of his man's masculine form. It seemed as though the muscle underneath was more defied than he had felt even during their morning romp. Tyler's foggy mind reasoned that he must have been working too hard not to notice. On the contrary, his reaction was to think he needed some time off to spend with his lover and really explore how much work Lucas's gym regiment had been doing for him!

Tyler's exploratory touch seemed to be having the desired effect on his lover's form, and Lucas growled in that beastly tone that prompted Tyler to look down. Feeling Lucas's malehood at half-mast again, Tyler was almost tempted to call into work and really service that cock to completion. How the protein shake and an increased workout regiment were providing Lucas so much stamina, Tyler had no rational clue. But, despite any reservations, he certainly wanted to take his man to bed and explore all that Lucas's new body had to offer. For now, at least, he would wait, his mind on the sex that the two would likely enjoy as soon as he got off work in the morning.

Without time to tend to his own needs, Tyler reluctantly prepared for work, but not before making his boyfriend another protein shake for his workout later that evening. It obviously had some immediate effects, as musk-drunk as Tyler was. He was determined to try it himself after his week of night shifts when he went to work out with Lucas again. Lucas, too, thought nothing wrong with his form, eager at all the changes that seemed to grant him the body of his dreams. Getting dressed to go to the gym without showering once again, Lucas took a few moments to really admire his form in the mirror. He had put on at least 75 pounds of muscle, most of it in his chest and arms, shifting his form towards a V-shape that made his cock bob and leak. His beard was noticeably thicker, a couple of weeks' worth of growth rather than the short time since he'd last checked himself out. His pointed elven ears certainly matched the appearance of his shaggy hair, longer and in need of a trim but rather fetching on his features just the same.

The only bane about going to the gym was having to don clothes, Lucas not wanting to cover up his sexy body. His workout clothes, though made of stretchy, breathe-through fabric, were now almost painfully tight over his broad shoulders and thick chest. Underwear was out of the question, especially with how turgid his cock remained. Going commando, Lucas made his way to the gym, cock bobbing up and down in his shorts and attracting the attention of both men and women alike. Lucas loved it!

Getting to the weight machines, Lucas decided to double his previous record from yesterday, feeling energized and ready to go despite figuring from experience that it would be a bad idea. His efforts were rewarded by the ease at which he lifted, pushing up and down in a steady rhythm that soon left him bored. It was all too easy lifting even what should have strained him last night. Lucas needed more!

Soreness was creeping into his muscles now, but not from the weight that he was lifting. The muscles were tearing rapidly from some internal force, spurred on by his need to get bigger and making the process momentarily painful. Yet, working through the pain, Lucas was rewarded with the reformation of muscle tissues, a process that should have taken weeks occurring in mere moments. And the size they added to his frame was significant, a visible inch in circumference that left the muscles tight against his shirt sleeves.

Pulling up over his stiffening abs and a forest of hairs over his stomach, Lucas could tell that even his elastic shirt was getting tighter, uncomfortably so compared to when he had donned it earlier. Twitching his shoulders a little was enough to cause a few tears in the fabrics, stretching them past the breaking point. Instead of being worried about his shirt, however, Lucas's ever-present erection grew impossibly hard, turned on by the sheer power he possessed. The thought of bursting through the confining clothes was almost as arousing as taking his lover's ass!

With a series of grunts and growls, Lucas flexed bulging biceps that were still swelling with growth even after such a meager amount of working out. The shirt sleeves split down the center, exposing itching skin that was writhing with the growth of new muscle. The torn fabric released a pungent whiff of male stink, making Lucas's cock pulse and leak with arousal. Excited by the prospect of tearing from his shirt and liking the comfort of relief against the tightness, Lucas reached up, claws catching on the fabric. Feeling them stuck, he pulled his hands away, rending the fabric with thick claw marks. With that, the fabric fell off in shreds, but it was of little consequence with how good it felt to be bare-chested!

Looking down at the sweaty, hairy skin, Lucas was elated with the sight of the thick treasure trail that now adorned his torso, pooling up from his groin and running over a mountainous eight-pack that was previously unthinkable on his frame. The hair was noticeably longer than the rest of the hair coating his form, though there was a light pelt covering him all across his sides and back now. It spread up towards his swollen pecs, thicker than the peppering of hairs that coated the rest of his body, and fanned out in a thick bush over his chest. The sight left Lucas excited beyond compare!

More than just elated, if the aches from his cock were any indication. His mammoth penis was tenting in his pants at this point, leaking through the fabric from his fat cock head. It was a nearly impossible task to prevent himself from stroking his shaft right then and there. Then again, why shouldn't he with how aroused he was? What did it matter who saw when he had such raw masculinity to show off? The more his thoughts went to the possibility, the more difficult it became not to do it right then and there. Consequences be damned!

Without regard for his surroundings, Lucas pulled down his shorts, left nearly naked now as his ass sweated all over the chair he was in. Clawed hands gripped his sheath, prompting his penis to rise from it, the reddened tip making him drool. Without waiting, Lucas started stroking off, his rank body odor, thick body hair, and sexy muscles making him just as aroused as he had been fucking his boyfriend. The pleasure was exquisite, his body a sexually charged lightning rod for his personal ecstasy. He couldn't have imagined he'd be so turned on by his male form, but having achieved his workout goals ten-fold was more potent an aphrodisiac than he was prepared for.

It soon seemed that his efforts did not go unnoticed. It was a small gym, and a large naked man jerking off was bound to attract some attention. The sounds that hit his twitching, pointed ears were mostly ones of disgust, his public display not being for that particular audience. Not for any audience than his boyfriend, Lucas found himself thinking, though was remiss to care with the needs in his loins and the power that he felt about his form. After all, why shouldn't he be able to release his seed wherever he was? It was his right as an alpha! Lucas remained largely ignorant of the reactions of the people around him, thinking them as lesser beings. Though, with his enhanced senses, he could tell that some of the men, either gay or not, did flush with arousal at the presence of such an impressive penis. Not to mention some of the women, though he was only flattered at their reaction, his inclinations were towards men in general and his boyfriend in particular.

It was thoughts of Tyler and what they had done together that had Lucas teetering on the edge of release. Though, his enhanced senses and his lust towards his growth and development were also key factors. Through slightly blackened nostrils, the thick stench of lust hit his nose and made Lucas stroke ever faster, desperate to show off his release. He did not care how many puny humans were watching. Part of his changed psyche deemed them beneath him, anyway, at this juncture, and Lucas would cum in front of them, their social conventions be damned. Such things did not apply to a beast such as himself!

"Ahhh...YEAH!" Lucas called out, rapidly spewing his load all over his groin and chest. The release was potent, wracking his body with sheer waves of ecstasy. He was sure, especially with enhanced senses, that he was alerting everyone in the gym of his masturbatory activities. But, he was an alpha being, a powerful predator, and free to take self-pleasure whenever and wherever he wished.

Not even caring that sticky fluids were covering him, Lucas got up, grinning lewdly down at all the people who were still staring. Lucas was their better, after all, and something for them to be jealous of. Still, their reactions were not ones of reverence but ones of disgust and panic. Lucas was, naturally, not bothered by this. But, it was...annoying, certainly enough to make him want to take his leave. This was not the place he wished to be, anyways. His body was more inclined to run through the woods or perhaps rut into his lover first before taking him for a ride!

Confidently, he walked off, regardless of what those still present were doing. Most of the onlookers were disgusted, but to his delight, a few grins met his gaze, bolstering his incredible confidence even further. Naturally, there were those that would worship the manly form that he possessed. They would have to remain jealous, Lucas reasoned, as he was eager to get home and enjoy all his body had to offer!

Getting to the locker room, Lucas grabbed his gear to leave, not caring he no longer had a shirt. His still semi-erect cock barely stayed inside of his shorts, though it was a moot point to the changing man. He didn't care if he ran through the night like the beast Lucas felt he had become. The only thing that bothered him, truly, was the sensation of drying semen on his form. Though, it was not the irritation that had him inconvenienced. Reaching up to rub at his beard, Lucas scooped up the bit of cum that had caught there and licked it up, not wanting to waste any.

For a brief time, Lucas pondered taking his shorts off and running through the woods once more, spilling his seed as many times as his enhanced stamina would allow. Though, part of him wanted to head back to the apartment to see the results of his latest workout. He felt larger, more powerful, and painfully erect at the realization. It was all his shorts could do to stay on his form, and for his bestial cock to pound out into the cool air as he played with himself for what felt like the tenth time that day with no ramifications to the skin of his penis, balls, or overall stamina.

Lucas soon realized the one other thing that kept him from jacking off in the back alley or tearing off into the wilderness as soon as he entered his apartment. He was starving, thankful that they had plenty of meat and that he could thaw and grill as much as he needed to satisfy his new appetites. It seemed as though after a good workout, he needed to eat, to devour and replenish the energy that his growth spurt required. Without cooking his food past the point of being blue rare, Lucas satiated his hunger for now and finally had the energy to review the latest products of his work. A few things had escaped his awareness until he took the time to check himself in the mirror. For one, a dizzying sensation made him raise his hands to his head, as though the dimensions of the room were significantly out of place. It was as though he was somehow taller, which even the most arduous workout would not allow. Still, rather than be concerned by the development, Lucas simply looked down in the mirror, admiring how much his larger stature accentuated his new muscle. He must have been upward of 7 feet now, a beast of a man and sexy as hell!

There were many more alterations to his form that should have been impossible but couldn't be denied. Weighing himself, he nearly broke the scales, now easily 100 pounds larger than he had been. His body was covered in hair, though he could still make out the shapes of rippling pecs, bulging upper arms, and a chiseled stomach. Not an inch of him missed any hair at this point, so thick in some places that it was hard to see the skin. A quick turn around showed that his back was almost as hairy as the rest of him. Even the backs of his hands and feet had a lovely coat of minute hairs. Not to mention his thick, bushy beard that was long enough to graze the tops of his fuzzy pecs and would be the envy of Blackbeard himself, or the wild dark hair that fell to his shoulders and would billow in the wind behind him as he ran! His pointed ears, which also had a light dusting of hair on the back, poked from the sides of the messy mane and perked up in sheer excitement and approval of his appearance.

The sight of himself in the mirror, still stained with cum from his previous release, was more than he could bear to resist his arousal. He was a massive, gorgeous beast, and wanted to properly worship his form as many times as was necessary to eventually achieve total release. Ripping his shorts off with his new power, Lucas looked down at his throbbing member, aching with the need to be touched. It must have been 10 inches now, as powerful a rod as anything he had ever seen. His erectile tissue was pumped full of blood, in particular a bit of skin at the base that was swelling like some sort of bulb. It pulled almost painfully out of his foreskin, which by this point was deeper and covered with wiry hairs. It looked almost like a bestial sheath, though, the sight only served to accentuate his obvious arousal...

"HHRRRGGGG...HHHHGGGHHHHH...ARRROOWWWWW!" Lucas grunted and growled, jerking himself off with bestial abandon. He didn't care to savor the sensations, not with how quickly he would recharge. It took him no time to reach orgasm, spraying his thick load all over the mirror and the floor. His only other prerogative was that he didn't want to waste precious seed, lapping it up like a dog licking up a treat on the floor.

Despite the release, he was still eager and ready to go again. But, for the moment, his body had other ideas. Still hungry, Lucas headed back to the kitchen, tearing into the steaks left out for his love and eating them raw. The entire time his hand remained on his cock, the tip leaking viscous fluids. Even the mere touch of his hand on his penis was enough to bring him to orgasm at least twice as he ate. Some of his semen even got on his dinner, though the salty load was only seasoning as he consumed many more pounds of meat than the human him could possibly handle. Eating it raw somehow accentuated the flavor, and the uncooked flesh did not even give him the slightest bit of indigestion as he finally ate enough that he felt full enough that he could rest.

A few hours of sleep did him wonders, his new form not requiring any more than that to recharge his batteries. Dreams were vivid and horny, filled with massive, tight asses and bestial forms to rut into. He was sure he came several times in his sleep, filling the sheets with his rank cum. The scent wafted into his nose and made him growl, almost enough to wake him several times.

With the raw surge of energy he possessed, he did not need to sleep long, waking refreshed and energized after only a couple of hours. Part of him longed to head out and howl into the world, running through the woods as he likely had the night before. Though, part of him recalled that Tyler had a short shift that evening and would be home shortly. As much as his sexual desires had been temporarily satisfied, he wanted nothing more than to make love to his partner, to show off the powerful form he had been granted.

At the thought of seeing his lover return, Lucas wanked himself off in the kitchen by the front door, fingering his sheath as he did so for added pleasure. He was slowly becoming distracted by several sensitive points along his chest, ones that hadn't been present before sleep though seemed to cry out to him now as he stroked himself off. Moving his hand over them in exploration, he was delighted to feel small bumps under his skin, more tender and sensual than any bits of skin had a right to be. Still, they gave him more pleasure than he had been expecting, and Lucas howled loud enough to shake the room, cum shot spraying over his chest as he released yet again.

His howls were in time to alert his lover, who was just then coming up the stairs to their apartment. Concerned, Tyler moved a little quicker to the door, opening it to a whiff of BO and musk that was more potent than anything he had experienced before. The sight of the man before him, seven-foot-tall and buff with inhuman facial features, and a very inhuman dick, should have been rather frightening. Yet, once more affected by the musk and the scent of rut, Tyler's guard was lowered, and he stumbled forward, as though unsure how to deal with the whole affair. It was taking everything he had to stand there, wanting to service the beast that he knew instinctually was his love.

"Rrrappy to see rrrou rrrome..." Lucas growled, a guttural quality to his voice that simply served to make Tyler harder. Lucas's cock barely had time to sink back into his sheath before coming to a full erection once more, still pumping out excess jism from his last ejaculation. Like before, he was prompted to reach down with a clawed hand and scoop up some of his semen, lapping it up with a tongue that was obviously longer than it had been.

In doing soon, he was soon given a better idea. "Gggrrret over herrrre..." Lucas growled, and Tyler obeyed as though in a trance. He looked up into the face of his lover, little remaining of his former human features. Yet, there was no denying it was Lucas. Part of his mind was just aware enough to realize that Lucas had achieved his goal. He had become the muscled specimen the two of them had always dreamed of, as impossible as it should have been. And he would be remiss for not taking advantage of it in the moment!

Hungrily, Tyler stared at his lover's penis, not caring that it was that of an animal now, clearly inhuman. Its 10 inches were drooling precum as its pointed tip seemed to stare at him. The sheer viscosity of seminal fluids was almost too much for him to take, though the flavor was far better than anything he could have been prepared for. He was certainly tolerant of seminal secretions, being a gay man. But this was simply divine, like ambrosia from the gods, and Tyler soon found that he couldn't lap it up fast enough.

Though the sheer girth of the shaft was too much for him to take in his mouth, Tyler was still eager to lick the tip, not letting a single drop of precum hit the floor. There was something tantalizing about sucking such a shaft, making him want to service such an Adonis of a male that his boyfriend had become. A beast such as this could have his pick of any male, or female, for that matter. But the fact that he came home to Tyler each night was more than he could have ever hoped for. He would worship his man to the full extent he could manage with his meager mouth!

Reaching up to rub the forest of hair that his lover had grown, Tyler was a little surprised to find a small bump on the left side, just past his chiseled abs. A growl escaped Lucas's lips at the contact, and, curiously, Tyler continued to rub the area, excited that it seemed to be pleasuring his lover. Though he never took his hand off his boyfriend's cock, he was still eager to tease the small nubs, enjoying how much it was doing for him. The cock bobbing in his mouth was more than he needed to worship his lover!

Still, glancing up, he was able to tell that Lucas's hands were playing over his chest and stomach in equal measure, directly above the one nub that Tyler had found and ones symmetrical on the other side. It seemed to Tyler that they were some sort of nipples, especially given the placement of the ones at the top. An exploratory hand eventually traveled over to the other side, a steady growl escaping his lips that had Tyler excited all over again. He was going to make his boyfriend cum, and the two of them would bask in the pleasure of that action!

The tensing in Lucas's testicles seemed to be reaching its crescendo, the skin firm and damp and not hindered by the frequent masturbatory sessions that Tyler could smell on his lover. He was truly a bastion of masculinity, one that Tyler felt blessed to preside over. Tyler could tell that his lover was about to cum and was eager to feel his man explode over him. The combination of pleasures from several sources could not allow him to hold back much longer. And neither man wanted him to.

Still, something caught Tyler's attention even as he prepared for the faceful of cum he desired so readily. A bunched-up pile of skin sat at the base of his penis, tugged taught by the massive bulge that swelled just above it. But, the skin seemed to be pulling up the man's groin, sticking to the skin as though putty was being remolded. With that, his cock was being angled upward toward Lucas's face. It wasn't preferable for Tyler's position, though he was more than inclined to readjust to make sure he was able to take the load in his face. Soon, the foreskin was nearly attached to Lucas's abs, stopping just short of it and having his cock lifted at a 70-degree angle.

The sensation was more than Lucas could bare. His balls swelled, preparing to pump Tyler with a face full of jism. Tyler leaned over it, wanting to take as much of the blast in his mouth as he could. He was literally salivating at this point, preparing to take so much cum to the face. Stroking Lucas with both hands now, he could feel the cock spasming, a literal howl escaping Lucas's mouth as he prepared to shoot his semen.

"AAAARROOOOWWWW!" He cried out with a bestial intensity that could not come from a human man, much less the man he loved. Still, neither seemed to care, both men concerned only with the orgasm that Lucas was currently experiencing.

Even with his mouth open and lips on the tip, Tyler could not have been prepared to take the sheer quantity of cum that Lucas needed to expel. Some shot down his throat, but the rest of it ended up getting on his lips, nose, and face, sticking to the skin and his facial hair. Tyler was eager to lap up as much of it as he could, the taste even better than the simple precum. Tyler felt elated, subservient to such a beast of a man, and he loved it, giving him a sense of place, of purpose.

Closing his eyes for a moment, Tyler was surprised to feel a wet, moist tongue on his skin, far larger than he could have expected from his lover. The sensation of an almost canine tongue on his skin was jarring, though the thick musk of cum made it hard to reflect on such things further. Eventually, he gave in to the attention, liking that Lucas was cleaning him up after their fun. And the man's rank breath only added to the masculine aroma that wafted off his body in waves.

Eventually, Lucas pulled back, regarding his lover with a curious expression as his cock started to bob up and down against his chest. "Turrrrn arrrround," he demanded, and Tyler did just that, getting down on hands and knees. Part of him wanted to go to the bedroom, to be taken there by his love. But with the level of command in his lover's voice, Tyler knew he did not have the time. Instead, he would have to allow himself to be bred then and there, force fucked by his lover as both seemed to crave.

Tyler didn't even have the chance to strip with the level of intensity of his lover's need. Rather, Lucas was more inclined to rip his clothes off his body, though not directly, not wanting to cause his lover pain. He was careful to use his claws to tear the rags off, pulling them down and off until even Tyler's underwear was removed. It took no time for him to rub his thick, girthy dick against Tyler's butt cheeks, ample fluids from spit, pre, and cum to lube up his conquest.

Yet, something was wrong. There was no way a cock the size of the one that Lucas currently possessed could fit in Tyler's tight pucker. Tyler would have taken it; in his musk-fueled haze, there was nothing he wouldn't try for his lover. But, given their differences in stature, Lucas was sufficiently pleased by grinding his cock on his lover's backside, teasing between his cheeks and coating Tyler's back and anus with plenty of lubrication.

Tyler, finally, allowed himself to touch himself, feeling days of pent-up lust built in his own modest cock. He wanted the stimulation against his prostate to aid his orgasm, though he had to settle for the pounding against his backdoor rocking his body and bringing him close. He was still far too quick to cum, sending him close to falling over the edge at any moment.

Despite his repeated releases, Lucas was close to his own orgasm once more, the refractory period almost non-existent with his current state of stamina. Yet, some other instinct was building in his mind, something new and unique. It was a desire that grew to an intensity that he could not prepare himself for until it nearly overcame him. Seeing his lover in his current, bent-over position sent a shock of dominance through his psyche that he could not ignore. He wanted, needed to reach down with his mouth as though to kiss the back of his neck. Yet, there was soon something else...

"AGGGHHHH!" Tyler cried out, feeling the pinprick of fangs piercing the back of his neck, penetrating the skin. Yet, his reaction was not entirely from the pain. Rather, the action served to send him into orgasm, blowing his load all over the floor. Tyler's entire body rocked at that, and Lucas held him up and close, easily able to support his entire weight. He even reached down to lick his lover's neck where he had bitten him, saliva sealing the wound. Though he knew it would hurt his love, there was no resisting the urge to bite, a powerful compulsion that overtook even his need to cum. Still, Tyler seemed not to care, body going limp from such an intense release.

Lost in his dominance, the scent of cum and blood, and his romantic feelings for his lover, Lucas took no time to reach his own end, blowing all over his boyfriend's backside. The sheer amount of cum pooled over the floor, and, like before, Lucas was prompted to clean up his lover and lick up as much semen as he could. The flavor was better than ever before, and even getting it in his beard did not bother the man as he lapped and licked with the eagerness of a cat licking a saucer of milk.

Tyler, by that point, had passed out, the pain and the pleasure in equal measure too much for the man to bear. Though Lucas hardly had awareness of it, the sheer force of the bite and exposure to his saliva was doing something to his lover, enough that he needed to pass out to endure the process. But, Lucas simply picked up his lover, moving him to the bedroom and setting him gently on the bed, tucking him in with a kiss as Tyler started to snore lightly.

Part of him wanted to lie down and spoon his lover as they passed out together. But. even after all the physical activity he had undergone thus far, Lucas felt restless and could not remain in bed for long. Experiencing almost boundless levels of energy, even after fucking his love multiple times and rubbing out a few extra loads by his own hand, Lucas went out at 5 am, aching for a good workout. He only thought it fit to don his final pair of workout shorts, barely covering the thick bulge of his sheath and balls. With some hesitance, he managed to find a shirt that his slightly larger boyfriend used as a nightshirt. It was barely enough to cover his chest, more like a crop top than anything meant to be worn over his form. Worse, it was powerfully uncomfortable, but there was no other choice if he was to head out in public. Save for running out into the woods, Lucas couldn't think of a way to burn off all the energy he seemed to possess.

It was still dark out, the moon just now sinking down over the horizon. Still, it was the earliest that any of the gyms in town opened, and thankfully it was one that was not his usual. Lucas thought that best, figuring he might get a warning from his regular haunt for his indecent exposure, though it was impossible to care given how full of his newfound strength he was. It wasn't his fault that all who saw him would be jealous of his form, after all!

Getting inside, it seemed like he was only one of a few patrons in the establishment as he surveyed the equipment, not sure where to start. The few people awake enough to begin their own workouts gave the man a double take, the thick muscles, beastly chest hair, painfully taut pants, and protruding face barely that of a man at this point. Though they were remiss to say anything, simply giving the man a wide birth as Lucas moved towards the benches, wanting to see how much he could lift now that he had changed so much. His body was literally a mountain of muscle, and he figured it would take little effort for him to bench even more than what was present in the machines.

Sitting at a bench press and gripping the handles, Lucas set himself to the maximum weight at the onset, eager to try his abilities and figuring he could do so with abandon. To his disappointment, the efforts hardly made the new muscles of his upper arms extend. He was already at the maximum weight for the machine and was pulling with the ease of a man that had been weightlifting all his life. It was almost disappointing that this was all he had to work with. Though, there was a certain excitement that he could lift them with such minimal effort, stronger than any man could expect to be at this establishment.

Already bulging muscles were swelling faster now, but Lucas was remiss to care, pulling the bars to the breaking point. It seemed that even the slightest bit of exertion was causing the continued growth of his body beyond anything he had ever seen on the human form. Though musk drunk and hyped on testosterone and adrenaline as he was, Lucas was more eager with the results than trying to rationalize how he'd obtained them at this juncture.

The one bane to the changes was that he was getting impossibly large for even the formerly loose garments still clinging precariously to him. The outline of muscles straining to free themselves was erotic on its own, making Lucas desire to see the clothing torn. Each pull of the machine seemed to draw the fabric tighter and tighter, micro-tears echoing until ultimately the true rips began. The forest of hairs that had continued to cover him during their sex itched fiercely against the fabric, making him want to rip them off to alleviate the discomfort. Though the thought of growing bigger and tearing out of them was more enticing than simply starting shirtless.

Lucas did not have to wait long to get his wish. With an eager rrriiipppp, his shirt pulled from its place on his frame, the arms breaking and his shoulders flexing forward to rend the fabric in half. The two halves clung to the sides of his back for a few moments until they slid off the forest of hairs that now coated him. They fell to the floor, Lucas sticking his tight shoe over them to rub them away, happy to be rid of them. He didn't need clothes, not for the powerful beast of a man that he had become!

Yet, that was not the only consequence of his steady increase in size. His bulging thighs pulled his gym shorts at the bottoms to the point that they were soon to tear. Excitedly, Lucas flexed his calves and thighs, popping the fabric even more as the rip spread up the jeans. The button burst off, and the zipper bent and broke before his muscled ass caused a tear to form at the back. It was almost more than his cock could bear, sliding from his sheath from sexual excitement. That, too, proved detrimental to the resistance of his shorts as they burst open, the muscles within too much for them to withstand.

Though he was not naked, not yet, it was obvious that the moment he stood, Lucas would lose the garb and stand naked and erect, not caring that he was in a public place as much as he hadn't the night prior. As though in response to the hormones flooding his mind, his cock started to throb intently. He was impossibly hard, though Lucas's thoughts moved towards his boyfriend as much as they were related to the bestial body he now possessed. Though, such a beast of a phallus could hardly fit in his boyfriend now. But he would make it fit to meet his desires!

Grinning lewdly, Lucas watched as the red lipstick-like phallus stretched from his sheath, towards twelve inches now without a discernable head. His thickening knot added another two inches to its length as his eagerness had the tip leaking from the sheer sight of it. It was clearly that of a beast, the lupine sheath pulling down around the base of it a sign that it did not belong on a man. But Lucas was hardly a man anymore, far beyond the muscle and bulk of anyone he had ever met or likely would. And he relished the sight of his penis, every bit the sign of his power and virility.

Given the massive, needy dick standing erect on his groin, Lucas couldn't help jerking off right then and there. Bestial growls escaped his lips as he started to stroke with the fervor of a man not being watched. Though truth be told, his growls started coming out reflexively louder, hoping to draw some attention to himself. The idea of being an exhibitionist seemed to make him harder, showing off his body to an entire gym that would never have a muscled, musky specimen like him!

Though there were relatively few people at this early hour, the sounds of them talking caught his pointed ears, things like "Gross!" "Not cool, dude!" "What the fuck?!" and even "Is he touching himself? Call the front desk! Get that shit out of here!" Yet, Lucas could hardly muster the energy to care, given the sheer lusty being he had become. They were beneath him, after all, and he wanted to show the world what he was and to have them in awe of his form and power.

The more he touched himself, the further the changes seemed to accelerate, as though the form he was becoming desired completion. He had been changing in increasingly inhuman ways the past few days, and now, the transformation was to come to a head, and Lucas had no desire to hold back. He loved every change that had overtaken him thus far, and the acceleration of the slight aches and itching only served to excite him further. The itching of fur and expansion of muscles made him an impossibly hulking beast even compared to what he had been. What would happen to him next? Lucas couldn't wait to find out. It was as though a moth busting through its chrysalis, birthed into the new form he had been craving ever since the changes had started.

Other changes were overcoming him that were arguably more extreme. Something seemed to poke through his spine, confined against the seat by his meaty ass and hips. It started to stretch, a line of skin and bone that spread apart the flesh of his back and extended outward as though a fifth limb, every bit as part of his anatomy as his legs and arms. Soon, it was two inches long and still growing, the tip poking from underneath him and trying to wriggle against its confinement. The ache and pain from his backside made him squirm in his seat to the point of needing to bend forward to allow room for a bizarre growth. The new appendage started to writhe in its confines before bursting forth, forming a lupine tail the likes of which no human had ever owned. Though it started off as hairless, it soon erupted with its own lupine pelt, matching the forest that already coated his back and chest.

A powerful tug began in his shoes, which he had barely been able to get on before. Now, it seemed as though his feet had expanded, stretching the footwear to the breaking point and beyond as his beastly body reached its final conclusion. Thick nails at the ends of the toes started to part the glue and stitching on the front, longer, twitching toes making quick work of the fabric. Stretched heels pushed at the backs, forcing his stance to the balls of his feet for when he was to stand up again. Already present pads thickened even further as Lucas kicked off the remnants, knocking them to the floor some distance away with the sheer power in his feet. He didn't need such footgear any longer, not while sporting powerful lupine paws!

The changes were coming faster now, accentuating his bestial features as he grew into a truly animalistic being. His face, which had been subtly changing the entire time, began to extend forth with a series of wet cracks, as though the bones underneath had broken apart and reformed after doubling in size. Though far from painful, Lucas was only aware of the discomfort, no more than anything he had experienced from his post-workout aches. It was a small price to pay for the form that his psyche seemed to crave.

By the time it was done, Lucas could see his black nose in front of his face, slits even further up its sides, and breathing in deep of his male musk and lupine stick. Curious, Lucas started to snap his growing jaws, feeling this thicker, pink tongue and massive, sharp teeth. It stretched far from his face, forming a broad lupine muzzle as his dentures thickened, altering towards their feral counterparts. They felt powerful, sharp, the fangs of a predatory, an alpha beast in any domain.

Yet, Lucas closed his eyes, all attention focused on his groin and the sensations of his paw hands bringing him closer and closer to release. The changes were a potent aphrodisiac, making him more aroused than at any point in his life. His cock, already altered towards beastly contours, was powerfully erect at 13 inches, knot and all. It stood proudly on his form, leaking copious fluids down the shaft and pooling into his sheath, making the werewolf moan. He wasn't going to last long and wasn't inclined to, despite the public nature of his current locale.

With his eyes closed, the scents and sounds in the room came to the forefront of his thoughts, though not enough to fully distract from his lust. The few people in the room with him were panicking now, yelling things like "What the hell!" and "What's happening to him?!" as one got up, snapping photos and videos while the other few ran out of the room in fear of his wolven form. Yet, Lucas was remiss to care, given the needs in his cock and how powerful his body was.

The smells, however, were most notable as he continued to jerk off with reckless abandon. Part of him was aware of the stink of humans past and present, how much they stank of fear and disgust at the changes and the display Lucas was putting on for them. But they didn't matter. The redolence of his own odor mattered most, the reek of his sweat and body odor, the scents of musk and cum and wolf that overtook his nose. It was impossible to hold out against the lust in his body with how potent the needs in his cock were becoming. He stank like a beast and he reveled in it!

Lucas was hellbent that he would masturbate himself off to completion here and now, making his form permanent as best he understood. And then, he would make sure to change his lover, too, making him a needy, musky beast worthy of the wolf cock that was about to explode at any moment. Best of all, Lucas was certain that his bite was infectious and that Tyler was the only one worthy of his attention, especially when his mate was a beast to match!

The thought of bringing his boyfriend into the fold was more than the changing man could bear, sending him over the edge into orgasmic oblivion. A howl pierced the room as Lucas came, exploding a geyser of wolf cum from his lupine rod and onto his chest, stomach, and the machine he was still seated on. Though sounds of fear, disgust and running reached his twitching ears, Lucas was remiss to focus on them any more than that. All he cared about was the waves of pleasure flowing through his body, nearly making him break the machine and rocking the room with his contented howls. He had cum, and he had cum hard, marking his fur and the room with the scent of an Alpha werewolf. Nothing else mattered save for bringing his lover into the fold. And soon, it would be time...

The hulking beast looked over the empty room, towering over everything at 9 feet tall and surveying what it had claimed as his domain. A fanged smile crossed his muzzle at the realization that no one was there, no fearful humans to bother him as he explored the range of his new body. The lingering scent of fear stank to his nose, and, in Lucas's opinion, was unfounded. Though he was hungry, for meat, of course, he wasn't there to eat anyone. He only wanted to work out and get bigger just like everyone else!

The stink of his own seed coated all over his fur, and, with newfound flexibility, reached down with his lupine tongue to lap at the cum covering his groin and torso. The flavor was exquisite, making the newly minted werewolf hard all over again. He would have touched himself once more, spread his spunk all over this territory to claim it. But, the distant sound of sirens gave him the notion that he was to receive some unwanted attention. Therefore, Lucas decided to leave this space for now, not afraid of the police but not wanting the competition for his territory. Besides, he had his lover waiting at home...

Though the phone was far smaller than the newly-formed werewolf, the sight of it gave Lucas an idea, one that made the already erect wolf-man leak even more. Dialing his love, the confused voice of Tyler hit his triangular ears and made him grin wide with his wolfish muzzle. After all, he had just planted the seeds of a lupine fate in his body through a bite and was eager to see where the fruits of his labors would give him...

On his end, Tyler was not expecting the deep cadence of his lover's voice, an animalistic, lusty growl that made the poor man shiver with pleasure. "GGGRRR...you just need to rest up sweetie...I'll be home to see the results...!"

******

By this point, Tyler was natrually concerned about his lover. Though a thick fog had crept into his mind in the past days, stirrings of worry finally started to poke through. As hot as it had been, was it really possible for Lucas to have gained so much size, so much muscle, and power in such a short time? Hell, was it even possible for any man to grow to a hulking behemoth with a cock to match? Not that he was complaining but...every time concern had crossed his mind, it seemed wiped away by the sheer presence of his beastly boyfriend. And, it had been welcome, certainly at the time...

The more Tyler reflected on it, the more he seemed concerned he had missed other changes, perhaps ones that should have been impossible but were clearly present in his recollections. The thick, musky stench, the body hair, the cock. As wonderful as it was to have it inside of him, it wasn't something that Lucas had sported before. Nor any other human, as best as Tyler could recall. Besides, the ears, the claws, and, most of all, the fangs, made him disturbed, certain those traits did not belong on a human. At least one that wasn't a human anymore...

At the memory of fangs, a phantom pain played through his shoulder. Tyler, though barely cognizant of it, reached up to rub the spot, thinking with some certainty that he'd been bitten by his lover during their last romp. Though, even rubbing the area was not enough to confirm such things, especially since there was no mark, no trace that anything had pierced the skin. Part of him thought it was some sort of hallucination or dream, though he could not be sure at the moment.

Still, first things first. Looking back online towards the protein shake recipe, Tyler was unable to find anything on it that implied there was nothing off about the powder. Double-checking the label left no indication of what it might have contained to give his lover such a powerful physique. All the ingredients were simple enough that Tyler could research those he did not know, unable to find anything amiss. Unless the mixture had been tainted with something else, his research led to a dead end.

All the while, a phantom ache in his shoulder bothered him, and Tyler contemplated going to the bathroom to rub some cream on it. Eventually, the pains forced him to relent in his online search, and he got up, a little dizzy from the change in vantage. Was Tyler maybe sick? It seemed like the room was spinning, as though he'd entered a space that was...somehow smaller than what he had expected. Or that Tyler had grown taller...

Making his way back to the bathroom, Tyler found he was looking in the mirror from a different angle than what he was used to. It was as though he had gained an inch in height, not something that should have been possible at his age, let alone in the few hours since he'd last slept. But, to his surprise, it was obviously worse than that, the face reflected there not the one he had worn. Tyler had to do a double take; the alterations to his visage weren't exactly obvious at first glance. But, the more he stared, the more he started to understand the beginnings of...alterations, perhaps even ones to match that of his lover. His beard, for one, though unkempt for the past few days, was clearly thicker, matching what he recalled Lucas having a few days ago. Was that right? Tyler found himself having a hard time focusing on it with the fog that had settled on his brain. It was almost more than he could bear to recall that anything was even wrong in the first place.

Yet, the alterations in front of him made him wonder if he had really just ignored similar alterations to his boyfriend's visage. First of all, his canines seemed larger, as though they had grown slightly, pushing the other teeth to the side. And his other teeth seemed altered, too, though seemed to cause him no pain or irritation. Stranger still, his nose had thickened somewhat, a brown patch of skin present at the apex that he couldn't seem to wipe away no matter how much he tried. In equal measure, the base of his nostrils seemed to have peeled back, forming little slits that twitched when he tried to flex them.

That wasn't the only thing to have altered upon closer inspection, much to his chagrin. It seemed as though Tyler's ears were pointed, the tips having stretched up an inch longer than they had been, almost impossible without the use of prosthetics. His previously absent sideburns had flared out, and the hair atop his head had grown out somewhat, as though he hadn't had a cut it in some weeks. To top off the slight shifts in his facial features, there was a yellowish glint in his eyes, as though they had developed some sort of flecks that shined when he moved into a certain way into the light.

Lifting his arms to rub his face revealed that the motion tugged on his nightshirt as it would if the shirt was a little small on his frame. The sleeves, in particular, were tight, noticeably compared to when he'd donned the shirt that morning. Rubbing his arms revealed a little more tone on his body than he had been expecting, more than what he had gotten in the last few weeks of workouts. Though the sex had been strenuous exercise, it certainly couldn't equate to this level of expansion. Putting his fingers around his arms, they were clearly larger, having swelling half an inch in diameter from their previous configuration.

It was then the persistent itching seemed to intensify, making Tyler shake his shirt a little bit to alleviate it. He decided, in the end, that it was warranted to take it off and examine his frame a little more closely. Yet, pulling it off seemed to confirm that it was snug, more difficult to remove than Tyler was expecting. In fact, the force needed almost tore at the fabric, and Tyler threw it to the floor, thankful he'd managed in his struggle. It seemed to get stuck on his fingernails slightly, and he was a little annoyed they seemed to pierce the fabric. A closer inspection showed them to be thicker than they should have been, their ends slightly pointed, matching what Tyler was sure Lucas had sported the other day.

Yet, it was the sight of his chest that made Tyler do a double take. Never the hairiest of guys, the source of the persistent itching was clear and present. His usually barely peppered treasure trail was thick, stretched down towards his groin, and itching fiercely, as though it was still itching with further growth. As dense as the dark hairs were becoming, it was increasingly evident that Tyler might look more like...why was it so hard to recall why he had found his boyfriend's form so odd over the past few days?!

A tingling in his groin seemed to intensify, and Tyler blushed for a moment as he started to come to arousal. The alterations were indeed sexy, had been so on his boyfriend's frame, and were equally welcome on his own. But there was a certain shape to his cock slowly creeping back into Tyler's mind, something red and beastly. Though, the more he reflected on it, the more the wisps of its visage came to the forefront of his thoughts. And the more the arousal grew, exciting the man enough to pull down his pants and see what he was packing...

Yet, the sounds of the door opening brought his attention to the kitchen, where he assumed his boyfriend would be coming back. Though it was early in the morning, the sun had not come up yet, and the light was off, so the room was still dark. Eager to see him, though, with more than a hint of trepidation, Tyler walked out into the main room, squinting.

"Lucas?" He asked though the figure did not move or speak. With his eyes still adjusting from the brightness of the bathroom, he couldn't quite make out the figure standing in the doorway. Why Lucas hadn't bothered to turn on the light was a mystery, not one that Tyler could readily identify. In truth, it made him a little nervous, in tandem with the voice he'd heard over the phone, too husky and growly to be readily identified as his love. The more he reflected on it, the more the beastly features seemed to creep into his recollections, though they did not bring with them the fear they might have.

Still, a mixture of dread and excitement prompted Tyler to turn on the light in time to see a beast that was far removed from his boyfriend. It was ten feet tall, hunched over to fit in the tiny apartment. Covered head to toe in wild grey hair, an obviously canine tail wagged behind the beast, as though a dog happy to see his master. That, in tandem with the thick black talons and the wolven muzzle, was the true shape of a beast, a lycanthrope out of legend, standing in his room, grinning with a mouthful of deadly fangs. There was no denying the terror that the creature invoked in him, enough that it was all he could do to stand there in its presence without running!

Yet, his fear couldn't quite override the sense of arousal that both the sight of the beast and its pungent sweaty odor seemed to illicit. It was a familiar aroma, a musky stench that had burned into his nostrils before making love with his boyfriend the past several days. That, in tandem with a gleam in the creature's eyes, sent a feeling of calm through his form. It was surely the natural evolution of the shifts that had burned through his lover's form, the epitome of the beastly, masculine frame. And, there was no way that Lucas would hurt him even if he was currently in the body of a beast.

But it was the sight of the powerful red rocket on the beast's groin that really assured Tyler of Lucas's intentions. He would willingly take such a monster inside of him if he could, though such was highly unlikely. Still, his arousal grew at the sight of the ten inches, longer with the knot sliding out of the sheath. It was that which had already been implanted inside of him, though it was clearly longer as befit the beast that Lucas now was!

"Like what you see, Babe?" Growled the wolf-man, Lucas's tone still present in the muzzle, though far more guttural than Tyler could have expected. But, it was all he needed to know that Lucas was still in there, still his lover, and had no intent to harm him unless the sheer size of his equipment was enough to do it! With that, Tyler stepped forward, not worried about what the beast might do to him, even though there was a very real chance he was in some sort of danger. The fact that the wolf-man was talking to him was proof enough, however, any such fears were not justified.

"Why don't you start by sucking me off, my love? You'rrre so grrrood at it," Lucas growled, and Tyler immediately felt at ease. This was the muscled, dominant beast he was in love with, and the new werewolfish persona only amplified those feelings. Tyler was elated by the offer to suck his penis just the way his love preferred!

Still, Tyler stared at the offering before him with a sense of dread. It was far too large to fit in either his mouth or his ass, as much as his musk-drunk mind desired it. Getting close to his lover filled his nostrils with the rank scent of wolf, of man and beast. Though Lucas could not produce any more with his hybrid physiology, he was already coated with sweat from his excursions. The aroma made him impossibly erect, though the haze present from their previous encounters seemed largely absent. Tyler was sure of what he was doing, understanding that his lover was a lycanthrope.

Still, Tyler was a little unsure of how to pleasure such a large dong. It was too much to take into his mouth, even with the changes that had overtaken him already. And he was certain that his rectum couldn't manage it, especially that thick knot. Settling for peppering it with kisses, the sensitivity of Lucas's love stick was enough that a growl escaped his lupine muzzle, and a furred, clawed hand moved down over Tyler's head, large enough to encapsulate it fully. Yet, Lucas was surprisingly gentle, the warmth of his pads on Tyler's head as he sucked at the headless tip.

Though Tyler loved the taste of cock on the worst of days, the aroma of musk and the taste of his lupine lover at this moment was divine, like Ambrosia from the gods. Lucas was leaking like a facet, and sticky fluids were running down Tyler's beard to the point that his tongue could not keep up. The odor of precum in his beard only accentuated his lusts at the moment, making him rut against the air in desperation. Though the size of the beast and Tyler's growing member allowed the confined cock tip to press against Lucas's legs, giving him a modicum of stimulation and enough encouragement to bring his lover to the precipice of release.

Lucas, for his part, loved the sight of what his bite had already done to his love; the extra body hair, the pointed ears, the muscle, and the thicker cock straining at his underwear. Though he found his lover's human form beautiful, he wanted to see the man of his dreams bulk up with muscle, grow a coat of fur, and topped off with the same lupine features that were part of his own anatomy now. He was creating his perfect partner and couldn't be prouder of the beast Lucas was becoming.

Given the sheer virility, Lucas now possessed, it took little time for him to come, his massive wolf testicles pumping sperm into a thick red rocket and blowing all over his lover's face. The thick semen ran down into the thickening beard over Tyler's features, though his seeking tongue was eager to lap as much as it could, the flavor more exquisite than even his previous masturbations. The rank stench of semen had Tyler more aroused than he had ever recalled. Rutting the air, a whine escaped his lips, though more wolfish than anything the former full human could ever elicit. Tyler was coming along fine, indeed!

Reaching down with a helping paw, Lucas pulled up his lover and licked the rest of the cum from the man's hair-covered skin. It seemed to accelerate the growth of hair, a thickening bead accented with long sideburns and a lengthy swash of hair over his head. Lucas lapped with gusto, slobbering with his muzzle as Tyler tried to kiss the lupine visage as much as possible. It was a little awkward, like kissing a dog, and Tyler couldn't help but giggle a little, the silliness of making out with a werewolf not lost on him. Still, at the moment, there was nothing that Tyler could imagine enjoying more.

Eager to explore his love's changes, Lucas gently gripped Tyler's arms, rubbing them down, coarse pads catching on the growing hairs. The warmth from the skin seemed in imply his muscles were bulging underneath, pushing against the skin as he bulked up. It only took a cursory glance to know that Tyler was growing, and had enlarged far more rapidly than Lucas had himself. It seemed as though the direct influx of lupine hormones through the bite was accelerating the process. Lucas would have it no other way, eager to rut with another werewolf.

Not able to wait for the changes to overtake him, Lucas's hands reached under his boyfriend's ass, pulling him up in an embrace as the two of them continued their messy make-out session. Lucas had to be careful with his new size lest he hit Tyler's head on the ceiling. Moving them both into the bedroom, Lucas carefully set his lover on the bed, getting on top of him even as the bed groaned. Tyler, for his part, knew what was coming, and felt his ass aching at the prospect of being fucked. Though Tyler was growing slightly, he was not at the proper contours to take such a mammoth canine member in his tight ass hole. But, with the heat rising in his body from both the muscle growth and hair spreading over his frame, Tyler figured that might not remain the case much longer. He longed to grow and change, to match the lupine visage that his lover now sported. Though, more than that, he wanted to simply be large enough to take such a glorious cock inside his rectum!

It seemed as though his desire to transform prompted the swelling of his chest, pecs flattening as nipples swelled with need. Pinpricks of sensitivity ran down his chest and belly in a line, and without missing a beat, Lucas started rubbing them with a firm claw, eliciting a deep growl from Tyler's lips. It seemed as though he had developed a series of extra nipples, ones that his lover was more than eager to ease into existence as Tyler squirmed and writhed in bliss.

His chest continued to bulk up all the while, muscle writhing under the skin before black hairs poked through like weeds. It ached only slightly to be growing so fast, though the realization was far more sensual than anything he could have imagined. He would have stared down at the sight of his belly thickened, toned beyond anything the gym could have ever done to him. But the hair quickly obscured the view, covering almost every inch of skin to the point that it formed a literal forest. Still, he could feel the muscles tearing, removing, and building back beyond humanly possible, exciting him with the knowledge that he had to be turning into a wolf like his lover!

Even better was the swelling of his arms, triceps, and biceps burning pleasurably with growing and swelling. Veins bulged over his arm, pumping the necessary blood to allow the tearing and reformation for an expansive tone that Tyler could have never hoped to acquire. Now it was something he aspired to now that seeing it was possible on his lover. Even his limbs were not spared by the expansion of the wolven pelt, though Tyler would not have it any other way.

The swelling soon spread to his legs, tightening in his pants to the point that Lucas saw no reason to leave them on his love. Tearing them off, though gently enough that he didn't do harm, Lucas rubbed the swelling thighs, his touch a catalyst for the growth of a swatch of fur over the skin, spreading down to his calves as they bulged with bulk. With nothing on his feet, both men could see the fur growing from their backs, the nails seeming to bruise though simply darkening into the beginnings of lupine nails. The bottoms of his feet looked like they had been dusted with dirt, though rather started to swell with coarse pads.

Of course, the notions of growth caused a surge of arousal to run through the changing man, and Tyler's prick leaked heavily in his underpants. The scent drove both men mad, prompting Lucas to reach down with his muzzle and start lapping at the leaking patch on the man's underwear, making Tyler squirm. Close as he was, Tyler could hardly hold back, and with the constant stimulation to his nipples and his excitement over the consistent muscle growth, his cock simply shot a modest bolt into his underwear, drank down by his lover like a creamy summer treat.

With the sheer arousal coursing through his being, it took no time for Tyler to come to full erection once more, having much the same stamina as his lupine lover. The heat and tingling coming over him were getting more intense, a sign that his member was the next thing to alter. With that in mind, Lucas caught the corner of Tyler's underwear and tugged, pulling them from Tyler's groin with a snap. The two were greeted by the sight of what had been a modest five-inch penis. Yet, it had swelled to at least seven now and was still growing with a deeply reddening shade.

With eagerness, Lucas puts his muzzle around it, as eager to drink down the delicious offering as Tyler was to feel his member grow. The presence of the mouth spurred him on again, and Tyler felt his penis pound out another inch, impossibly thick for a human though closer to the girth of something that a werewolf might support. He could feel his tip getting pointed, the base swelling faster than the rest of his penis as though forming the basis of a knot he was going to grow. The foreign shape, though something that should be frightening, was rather elating, showing that Tyler was becoming something greater, more.

As though his boyfriend was actively pumping the meat and muscle into him, Tyler could feel his arms bulking up, chest expanding, and thighs swelling beyond what his dreams could muster. It was everything the pair of them would have wanted more, far beyond the possibilities they could ever conceive. It was exhilarating, and Tyler was barely able to hold back his semen as he was sucked off with the skill that only a werewolf's muzzle could muster.

It was more than just the size of his bulk that was altering his features. He was getting more and more bestial, his fingernails sharpening into thickening claws, enough to scrape through his lover's skin if his hair wasn't so thick. His canines protruded through blackening lips, almost sheering the flesh though largely a non-issue with how tough it was becoming. His nose was flattened, slits up the slides, and an increased rostrum drinking in their pungent musk, making him leak unto his lover's muzzle. Pointed ears soon gained the ability to twitch, making him growl with excitement for having the newer, more motile appendages. And all the while, his thickening body hair hid away any sign of the skin underneath.

Yet, all of that paled in comparison to the size of the lupine knot developing under his lupine lover's skilled ministrations. Another inch longer now and still tingling with further growth, its development left Tyler powerfully excited. He realized with certainty that he, too, was to become a werewolf, and he rejoiced at that. Tyler wanted to be a sexy werewolf to take his boyfriend's cock, the only form worthy of such a behemoth. With that knowledge firmly in mind, it was almost impossible for the changing man to hold back, and he growled and grunted, feeling the tension build and the pressure blow his load through his shaft.

"AAGGGHHHH FUCK YEAH!" Tyler yelled out, with no regard for his surroundings as he came, a pent-up loaded that felt amazing to be released. He had been so horny since the changes began, allowing his boyfriend the pleasure of lapping up his load as much as Tyler loved taking his own. Yet, even coming down from the face of such a mighty orgasm, his now massive cock was still erect, still eager for more. The stamina was beyond anything he could have expected, even though he'd seen the same thing in his lover. It was an unhuman level of euphoria, though there was steadily becoming less and less humanity left in his being!

As though his wishes were the cause for further changes, Tyler could feel his frame bulking up all over even more, muscles crawling closer to match the stature of his lover. He hardly wanted to be that big, just slightly closer, the smaller of the two and subby to his dominant wolf. Alpha material, though Lucas had taken the mantel willingly, loving his boyfriend all the way. And, as the changes seemed to be coming to their conclusion, he seemed to be getting his wish as Lucas rose up, kissing his lover on the lips as they made out with the enthusiasm of two long-term lovers, reunited in body as much as they had been in time.

Still, the ache in his asshole was becoming paramount, and Tyler desperately wanted a lupine phallus inside of him to mediate the orgasm he wished to experience. Taking his lover's paws in his own developing ones, Tyler pulled him downwards, Tyler getting on his back and looking up with pleading yellowed eyes. Raising his backside, Tyler allowed his pucker to be on full display, clenching open and closed in a presentation of his eagerness to be bred and fucked.

As he did so, something started to push from his backside, wriggling as soon as it was able to do so. Tyler was a little stunned, barely able to control the appendage, as though it was moving of its own accord. His new tail was still wagging as the tip of a lupine cock started to push in, his sensual flesh already eager and open for him. The pair didn't even require any lubrication to enter, Tyler eager and open while Lucas was leaking like a fountain, able to ooze all over the edges of his lover's rear. With how turgid he was, there was little effort required for him to push all the way in, making Tyler growl at the desired penetration. Tyler was elated; never before had he been opened up so fully. Rather than the pain of something so large stimulating him, Tyler's altered anatomy was able to take it now, allowing him the maximum pleasure as his prostate was pounded by his lover's eager prick.

Lucas, too, was in heaven, the sensation against his cock almost more than he could take, making it difficult to make it all the way to the hilt. His insistence was rewarded with his lover's opening taking him in like a clamp, as though Tyler's body itself was drawing him inside, to be against his prostate and give him the pleasure that Tyler desired.

"Alright, honey?" Lucas growled, though the bestial instincts in his mind hardly made it possible for him to resist holding back, even if his efforts were causing his lover harm.

Still, he needn't have worried about how changed Tyler was already. "More...give it to me, babe!" The beta begged, and with a growl, Lucas pushed into the hole, holding it there for only a moment before the pair of them got their fucking rhythm going. They rocked together with the familiarity of lovers before getting into it with bestial intenstiy, using their new bodies and stamina to full effect as they rutted with the ferocity of beasts.

The fucking had another effect on Tyler's physiology, he still being a little too small in comparison with his lover. The masculine specimen with lupine features stretched out to match the wolfish visage of his boyfriend. Reaching out to kiss his lover, Tyler was briefly inconvenienced by the fact that his face was not long enough to meet Lucas's muzzle. Though, it was not to be an issue for much longer, cracks and pops in his jaw, pushing it forward and allowing the teeth to fully form in his lupine jaw. A flattened tongue reached out and licked at Lucas's lips, which he pulled back to allow the gesture. It seemed to be a sign of submission, though in action only. Despite lupine desires, the two of them were equals, playing to the sub and dom forms in the bedroom alone.

With the increase in muzzle size came a plethora of senses beyond even what he'd experienced thus far. Though, his thicker nose breathed in their musk, implanting the wolves they were to memory. His ears were focused only on the heavy breathing and the steady grunts of his lover, and his golden eyes drank in the shape even in the dark room, the waning moon's reflection all the light he needed to see the sexy form of his boyfriend.

Best of all was the pressure on his anus, which he understood was the lupine knot seeking entry. The sheer size of it worried Tyler, though not through the pain of penetration. Rather, was he big enough to take it? Tyler pushed out with his rectal muscles, desperate for that contact and wanting to fully submit and feel the two of them tied together. In response to his efforts, he could feel Lucas's thrusts growing more insistent, making him want it as bad as his lover evidently did.

"Please, my love, knot me! I need it! Make me yours!" Tyler managed to moan his desperation, though only just.

Lost in lupine lust, Lucas could do little but growl his desires as he shoved forth, not caring for his lover's confront at the moment. The resistance to his intrusion seemed to wane the faster he fucked, as though Tyler's rectum was elastic enough to take what was being offered. Tyler wanted desperately to receive it, Lucas was sure. They were of one mind in their lust, and Tyler simply growled his desire even with the roughness that was taking over Lucas's mind.

The slick slapping sound turned into a sucking that pulled Lucas in, the knot popping into place and making Tyler moan from the pressure. Though, it was an amazing pain, one that pounded his prostate and opened him up in a way that surpassed all expectations. Lucas was aware of how much his lover needed it and forced himself into a tighter sensation than anything he had ever experienced. Cock engulfed as it was, there was no chance of the newly minted werewolf holding back, as with an earth-shattered howl, he came, expelling his testicular contents inside of his lover's insides. His cock spasmed and jerked uncontrolled, the best orgasm he had ever experienced, even surpassing those within the last few days. They were both fully lupine, after all, Tyler was the perfect stature to take his wolf-hood and allow them to revel in the bestial bodies they now possessed.

At the sensation of being filled with wolf cum, there was little hope of Tyler holding back, especially with the forceful intrusion and its effect on his prostate. He, too, howled out his release as his spasming cock blew over the two of them in waves, several thick blasts that coated their already musky fur. The release was intense, making Tyler reel back from the force of it. He couldn't help but think, even in his musk-drunk state, that it was the perfect baptism into his lycanthropic form. And with the love of his life, Tyler could think of no better scenario than the one he was currently in.

With that, the two of them lay there, Tyler's smaller body still powerful enough to hold up his slightly larger boyfriend. Lucas felt his body going limp, resting from the intense release and the lack of sleep. Though the wolf he was didn't need much time to recuperate, and locked in with his love as he was, the two lusty lycanthropes rutted again, penises erect and eager for another round or two before they were finally sated.

Eventually, after what seemed like an eternity of bliss, Lucas's knot popped out with a rush of semen, more than what he was expecting that he had been able to release. He wanted to lick at it, though the energy in his body had returned fully after the brief rest that he had received. It seemed that Tyler had the same inclinations, not wanting to waste a drop of precious cum. The rank flavor was a sign of their masculinity, the power, and the promise they had been striving for ever since they had begun their rigorous workouts.

With that, the pair burst out of the front door, ripping it off its hinges as they ran into the early morning light. Though there was no way for them to avoid being seen by those starting to go about their day. But, both wolves were remiss to care, powerful alphas in their own right and eager to take what was owed them. Though, there was nothing in the city, the human world that appealed to the pair of them. Rather, it was the world of the woods that called to them, to run through branches and brambles until the morning sun burned into their hair and they howled their release and reveled in their new bodies, experiencing a taste of true freedom...

******

The warm sun was high in the sky by the time the two humans woke, naked and still much the peak physical specimens they had been. Lucas roused first, and found himself confused as to where he was or what he was doing here. Far from his bed and even home, Lucas seemed to be in the middle of the woods, not his usual place to sleep. Though, the settings were familiar, and not just from the sight of it. His nose told him all he needed to know, of their wolven fun and the beastly bodies Lucas and his boyfriend had acquired.

It was soon apparent that he no longer had the wolven visage he recalled from the night prior. The tail, the claws, the muzzle, and the fur were all absent of the human features he once possessed. Yet, not all the alterations from his time as a wolf were lost. He looked far more than wolf-man in stature than he had the scrawny, twink of a man that he had been. Lucas took a moment to really examine his body, rubbing the ample body hair that now covered him, making him a bear of a beast. His nails, too, were thicker, and darker, though were passable as human if someone didn't look too hard. His skin seemed darker as well, the firm muscle just underneath and making the changed man moan as he rubbed thicker hands over it. He was near the perfection personified to the point that his physiology would make him fit for world weightlifting. It was more than he could have managed in his wildest dreams, and his boyfriend seemed to have the body to match.

Though, there was some precedence for enjoying the wolven visage he had not hours ago. He had looked sexy that way, loving the knot above all, and having it implanted in his lover's backside. Though he figured that wouldn't really be an indicative model for functioning in the human world, as jealous and scared as passersby might be of his physique. And, as much as he longed for lupine features, Lucas was sure that either the moon, another shot of the protein drink, or a few good workouts would bring out the wolf in him again!

To his delight, looking over at his still-sleeping naked lover, Tyler seemed to sport the same altered build. He looked bigger than the largest jocks on university sports teams, more akin to actors that spent their entire lives trying to maintain the physiques that made them millions. It wasn't too much, not enough to hinder their movements or day-to-day lives. But they would both certainly need a new wardrobe! A small price to pay for the bodies of their dreams, to be certain.

Naturally, the thick musk of their sex and unshowered forms rang in their noses, human though they appeared at the moment. It made Lucas's cock slightly erect, despite the frequent fuck sessions the two of them enjoyed during their tenure as anthro wolves. The stamina that they carried as wolves seemed to carry over to whatever had happened to their forms, exactly as Lucas would have imagined and hoped for. And, of course, it was the sleeping form of his lover that did it for him as Lucas stared down at the sleeping man with hunger.

"Ummm...Morning, Babe," Tyler managed to mutter, awakening to the presence of his lover staring at him, certainly not an unwelcome thing. In response, Lucas leaned down and gave his boyfriend a kiss. The scent of musk and the stink of their male bodies rolled into each other's noses, making both as hard as they had never been. Though they were naked in the woods, there was certainly time for them to have some more fun before figuring out what it was they were to do now.

It took little time for both men to come to full erection, making out as they were and lusty as their scents and bodies made them. Despite the ground being rough, their hairy bodies prevented any activities from injuring them. It was therefore hardly an inconvenience for Tyler to get down and raise his legs to take his lover inside of him. Lucas got down as well, cock entering Tyler's abused anus easily and allowing them to quickly fall into a rhythm. Within a few minutes, Lucas blew his load, and Tyler covered the two of them with several thick spurts. All the sex they partook into this point was still insufficient for their lust to abate, and they lay there, wrapped in each other's embrace. Even a semblance of Lucas's knot remained, at least enough that the pair could remain tied together for a brief period.

The lovers lay there, post-coital left down allowing Lucas to finally slide from his hole, the base still swollen as a remnant of his lupine essence. The duo looked at the setting sun, moon soon to take its place over the landscape. Though it would provide them some cover of darkness to return to their homes and their lives, there was another possibility, one that sat well with both former wolves. Perhaps the moon would revert them to their desired forms, to the wolves that could run through the woods and fuck with bestial intent...
