This was commissioned story by a furry who wanted to remain anonymous.

I actually really enjoyed writing this one, a few of my own personal kinks were requested in this one. Hopefully you enjoy it too.

Huzzah! My first story that isn't insanely long! Plus, it isn't a transformation story. Best of all, the smut shows up pretty quick!


When a young gym goer decides to get cardio in "privacy" he gets his cardio, but no as he expected....


Lockers slammed shut, towels flung over shoulders and bros taking nude selfies. All the typical activities you'd find in BeastMode Gym® on a Friday evening, especially during 5 p.m where almost everyone there was getting a pump on so they could look bigger when they would go out to the clubs and bars later that night. Humans and anthros alike, the change rooms and showers were filled with jocks of all shapes and sizes. However it was definitely the anthros who stood out more, usually by their size and especially, their arrogance.

Yet, while most of the gym patrons were getting ready to leave, a young human named Kyle had just arrived. Usually on Friday nights he had nothing going on, he saved most of his plans for the weekend. Luckily for him, when he arrived this late, the gym was mostly quiet; except for him and a few other anthros, mostly. The human had begun to come to the gym on a regular basis for a few months now, and had rapidly gained a good deal of muscle mass to pack on his still-lean frame. But he was still nothing compared to the anthros that were hitting the weights right now and some of these guy were HUGE! A horse, bull, and a wolf had been working out together. All of them must've been over 6'6 and boy did they have some serious muscle on them, bench pressing 4 plates on each side as if they were nothing. Kyle looked away, towards his own bench from the distraction, he had to focus on his own workout.

To put it simply, Kyle was gay. Not only that, but he was insecure when admitting it to other people. His friends were progressive enough, but it was more of his own internal shame of how his friends would see him if he admitted his attraction towards the same sex, let alone to anthro species. For this reason he never had sex with someone else before. Sure, he fooled around with the occasional woman, but that was to hide his sexuality from his friends. Lately this secret had become maddening; it was bad enough hiding his secret from friends and family that probably wouldn't even care, but it also prevented him from chasing after one of the sexy muscle studs that went his gym.

"Oh well." He focused on his workout; chest day, always his favourite workout. His workout was going along well, but the muscular anthros a few feet away from him were busy showing off, the bull was flexing his huge arms and the horse pumped out his vast chest, a prominent valley outlined underneath his thin wifebeater while the large wolf looked on complimenting his buddy's herculean physique. Usually this only created a slight distraction, but today it was a lot more than usual. He thought he could even smell the musk emanating from their bodies. The earthy pheromones started to have an effect on him, noticeably around his groin. He had to move away to hide his rising boner. While he had an idea his friends and family had no ill-will towards homosexuals, he had no idea if these sexy anthro jocks were as open and he certainly didn't want to find out.

Staying as far away as possible, he tried to balance his workout, doing a couple sets while admiring the eye candy, but his hard on continued to threaten to pitch a noticeable tent in his shorts.

"Damnit, this just isn't gonna work today."

Kyle walked out of the gym area, silently cursing under his breath at the distraction, even as sexy as it were, he was there to pump iron, not to get a strip show, with potentially disastrous results if he and his dick were caught staring.

"Guess I'll just hop in the pool, that should make this nuisance go down for now, I can take care of it proper when I get home."

He quickly swapped his Under Armour shorts for an actual bathing suit and padded off to the pool. No point in leaving because of some sexual tension, the young man had dedication. He wanted to at least get some cardio done to keep himself in shape, and above all he really did enjoy swimming. The feeling of water moving around him was stimulating, yet soothing.

He opened the door into the pool area, the sharp smell of chlorine hit his nose, quickly removing any lasting pangs of sweat from the three anthros in the gym. The decent sized lane pool was empty, save for a rather large otter that was dashing through the water in laps like only an otter could. He moved so fast and gracefully for an anthro his size, usually otters we thin, lean and toned, this otter was toned, but he sure wasn't thin. While he wasn't as large as the buff jocks in the gym earlier, he was still huge. Large muscles were spread through its body, flexing and extending with every textbook stroke and kick through the water. It was a magnificent display of athleticism and Kyle was certainly impressed. He had seen the otter around a few times, only on the gym floor though and never this scantily clad. It was a little difficult to see through the surface of the water, but it looked like the otter was wearing a tight red speedo. It complimented his nut brown fur so well, the human thought. Kyle was standing near the edge of the pool with his mouth unconsciously agape, staring at the anthro gliding through the water. A tingle shot down his spine and into his balls.

Until it stopped at the far side of the pool and called at him.

"Yo! Can I help you with somethin'? You look like you're lost bud!"

Caught off guard, the human replied, a little meekly, "Oh...yeah, I was just about to do a few laps in the pool."

"Well come on in man, the water's great! I'll head over to this lane so you got some room."

Kyle perked up, "Hey thanks bro!" He quickly draped his towel over a nearby chair and climbed down into the water right next to the anthro. The otter's words were true, the water felt refreshingly cool and he was eager to start swimming.

"I've seen ya around before, but I never introduced myself, names Corey." The otter grinned wide and held out a large paw.

The human reached out and shook, "nice to meet you, I'm Kyle." He offered a genuine smile back at the large anthro who was looking down at him.

"Well Kyle let's see what'chu got!" Corey leaped off the pool wall and began to slice through the water in a perfect front stroke.

It almost seemed like a challenge to Kyle, he set off in a breaststroke of his own but quickly realized that there was no way he was going to catch up to the otter's speed. After all Corey's species was made for swift swimming in the water. Kyle gave up and decided to go his own pace. While swimming though, he finally got a better look at Corey's body, it certainly was a bright red speedo alright and boy was it tight. It slipped just under his thick rudder tail and hugged his large round cheeks perfectly. Fortunately the water was cold, otherwise his boner would have ripped right through his own bathing suit. The amazing view was short lived though, as the speedy otter zipped right by the Kyle.

Once Corey got to the opposite wall, he alternated his style to a backstroke and Kyle tried to look a subtle as possible as the big anthro headed for him. He was treated to a view of the otter's ample bulge just rising over the water line lapping at the otter's hips. The red fabric stretched neatly over Corey's package giving a good outline of how big he was; the huge balls could clearly be seen just below the visible snake trapped inside the red spandex. Cold water be damned, Kyle had started getting a semi despite being in the water, and being in the water, he wasn't sure if he was salivating. The otter's body was simply big just about everywhere and the speedo hugging his ass and package left extremely little to the imagination. The human had just found his new jack-off fantasy for the next few weeks...maybe months.

Kyle somehow managed to hide himself rather well, and focused on the last few laps of his swimming. As he picked up the pace, Corey slowed down his and Kyle actually managed to pass the buff otter, but as he started separating the distance between them, a large splash was heard just behind Kyle as the otter changed back to a front crawl and closed in on him in attempt to pass. Kyle continued to speed up, his muscles utterly burning in agony, thinking he could make the wall first, but the otter quickly shifted into his lane and in mid-stroke, his webbed paw landed right on top of Kyle's ass! It gave a quick squeeze before it flew right off and into the water as the otter passed the human for good and reached the wall.

Kyle was absolutely stunned, he had fallen below the surface and swallowed a good deal of water. He had a good momentum going until that paw grabbed his behind, it felt almost intentional, but he wasn't sure, maybe just to stop him so Corey could beat him to the wall. Either way, his cock had shot out completely, making once again a noticeable tent in his trunks.

"What the heck was that for?" Kyle yelled at the large otter.

"Heh, whoops! I was going so fast that I hit ya! My bad!" Corey was cracking up, "Well, it stopped you enough that I reached the wall first anyway!" He continued to laugh at Kyle's small "misfortune."

'Hey, calm down man, I'm sure you liked it more than I did!" Corey teased

Kyle had become mockingly defensive, "Yup, cause I just love getting my ass groped by some random guy and swallowing water."

The otter jumped out of the pool shaking water out of his matted hair. "Meh, sorry man, but it was still funny, I don't know about you, but I'm gonna head to the change room. You coming?"

"Yeah, I'm right behind you." Kyle climbed out and followed the otter out, grabbing his towel and throwing it over his shoulders. He got a good look of the otter walking, the speedo was definitely too small for him, it threatened to fall or split around the large rump it containing, the thick tail swished back and forth as Corey walked, flinging some water off with every step. It was total heaven for Kyle, if only he could find a body like that to have for himself. The arousal started to creep into him, but the walk into the dark changeroom abruptly ended those thoughts, possibly for the better.

Corey turned around in front of Kyle this time, giving him a close up view of his tall front; he had a cute face definitely, his chest was large and a ring was hanging off both of his nipples. He boasted a flat stomach with wasboard abs covered by a thin layer of nut brown fur with a larger bush that extended down towards his speedo. Kyle noticed that bulge, _that thing is huge, how much bigger does that thing get when it's hard?_He so wanted to find out, but there was no way he was gonna summon the guts to ask this otter to show him, for all he knew, the otter was straight.

"Kyle? Hey man, I was gonna head to the sauna to relax a bit if you wanna come, we can chat for a bit."

Kyle's gaze quickly shot up back to the Corey's face above him, "oh yeah, sure why not."

Corey smirked as he took his towel out of his locker, not bothering to change out of the tiny garment, he walked towards the sauna, Kyle following him sneaking more gawks to the otters muscular body. But the otter caught the human staring in one of the glass windows, his grin widened, he knew the human was staring at him ever since he got in the pool. The ass grab was certainly not an accident, just testing out his new catch. Corey was gonna have his fun with the kid, and damn that kid was gonna enjoy every minute of it.

The sauna door opened and a blast of steam escaped from the room and into their faces. Corey and Kyle both walked in. Almost immediately Kyle began sweating, he took a seat on to the bench as the large otter padded over to the rock steamer and added some more hot water, adding even more heat to the room. The large anthro shuffled back to the bench to sit down and recline right next to the smaller human. His towel draped over his shoulders as he closed his eyes and sighed.

"Feels good eh? I hope you don't mind, but after a long swim, I like it hot."

"Definitely." Kyle sighed in unison. Sweat continuing to rush out of his pores, soaking his skin, giving it a healthy sheen in the dim light. He snuck a quick peek at the relaxing otter; Corey seemed to be sweating just as much as him, it matted the dark brown fur on his head, curling slightly over the top of his eyes. The increasing moisture darkening his nut brown fur over his body from top to bottom. Even his red speedo had become wet and started to take on a darker hue. Kyle looked over a bit more intensely, Corey didn't seem to notice; his eyes were closed, almost in an hypnotic bliss. The darkening speedo had better outlined the mustelid's package, the balls must have been apple sized, how they fit inside the small garment was a mystery his gaze moved up and boy did his member look delicious, it was human shaped dick and he thought he could make out a rather generous amount of foreskin at the tip. Kyle licked his chops at the thought of that monster in his face. He was tempted to just bury his face in the wet crotch and just sniff it.

A stretch by Corey knocked him out of his fantasy, but to Kyle's relief it didn't look like the large otter noticed his staring. At least to him anyway. But as the mustelid stretched out his limbs, his musk hit Kyle like a brick wall, the scent was so strong that his gaze became hazy. Corey's thick pheromones mixed with the steam as it permeated the room. The earthy smell chipped away at inhibitions, the otter noticed this and smirked, he raised his arms behind his head, allowing more of his scent to reach the human. He wasn't dirty, but he was still a mammal and had scent glands, some that were meant for attracting potential mates, and there was one right next to him in the form of Kyle. But Corey was passive, he was gonna let the human get what he so wanted.

"See something ya like? I'm not gunna stop you."

Kyle had lost almost all of his inhibitions and reached out a hand to sample the good that was so thinly guarded underneath that tiny red garment. "I just want to try....wanna see y-your dick."

Kyle grabbed the otter's package through he speedo, his member squirmed around his touch, the ample sweat making wet "_squelch"_sounds as Corey's junk was played with underneath his clothing. This was fun for the otter, but he felt like things needed to be pushed along just a bit.

Corey's hands grasped the hem of his red swimwear and ever so slowly pulled them down, uncovering his hardening member and a pair of heavy furred nuts. Kyle's eyes widened as his prize was brought into view. And without hesitation, he knelt in front of the otters spread legs and cupped one of those large balls into his hand. He leaned in closer and took some of it into his open mouth. A salty taste enveloped his mouth and he loved it, he rolled the sack around with his tongue and he heard Corey give off a sigh, it was clear that the mustelid above him was enjoying this and Kyle was going to try his best to make sure he would love this as much as himself.

The human turned his attention over to the over nutsack and gave it a good tonguebath, running his tongue over the sensitive fur, leaving not one part of the otter's scotum dry. He moved his mouth just a little bit north and found that glorious cock. He wasn't sure he was going to be able to fit that beast inside his mouth, but he definitely wanted a taste of this piece of meat. Using his hands, he lifted up that otter dick and began licking it, starting from the base, Kyle licked up the shaft, ending at the thick skin covered head. He did it once again, the dick had a distinct flavour of its own, not as salty as the sac beneath it, but he loved the taste all the same. Corey's member swelled up and became hard, not needing his hands to keep it up anymore it stood up straight at an impressive height.

The head pulsed in time with the otter's heart beat, the head almost completely covered by the foreskin, only yielding a small opening where precum bubbled up and flowed over the rim of the skin covering, slowly leaking down the shaft. Still camped between the anthros thick legs, the human lapped up the copious precum, following it up to its source. Kyle snuck his tongue underneath the foreskin, tonguing the urethra slightly and swirling his tongue inside the prepuce, tickling the underside of the broad head and coaxing out a loud moan out of Corey, eyes closed in bliss.

The otter's cock was so big that Kyle was able to wrap both his hands around it and slowly stroked it up and down; every downward stroke pulled the foreskin down, exposing the pink head, always to be pushed back over again. The flow of precum had only increased, the was a steady stream running into the foreskin, covering the glans with enough to gush down his shaft, polling between his nuts. Corey had his eyes open now, looking down at Kyle with half glazed eyes, and a half smirk, trying hard to control himself over his enjoyment. He pushed Kyle away from his member.

"C'mon pup, take off those trunks and have a seat in daddy's lap."

Kyle was panting now, his sunset gaze hiding none of his horniness. As Corey commanded, he stood up and pulled off his bathing suit, his own erection leaving a large tent from poor neglect, was finally brought into play. The large otter purred at the sight of it, and motioned the human over with his webbed finger. Kyle climbed onto the sitting mustelids waist, wrapping his legs around the otter's abdomen and using a hand to grasp Corey's wide arm. Both their dicks rubbing against each other.

Corey gave a smirk to the human's dopey lust-smile, he grabbed his hefty cock, and angled it toward the humans; he rubbed the half-covered head with the Kyle's, smearing precum and the human's own saliva over it, leaving it saturated. The otter lined up their dicks and pushed his foreskin past his own head and well over the smaller one, docking them both in his ample foreskin.

The humans eyes rolled in the back of his head, his cockhead enveloped in the skin's warmth while gently rolling around with the otter's glans. He instinctively humped into Corey's prepuce, almost as if it were a hole of its own, a wet sploshing sound was made every time he humped inward. The foreskin sealing in both of the males' precum, the gentle rubbing throwing both of them into ecstasy, Corey's heavy breathing created a mist surrounding the smaller human. While Kyle's moaning echoed through the warm walls of the sauna.

With such a virgin sensation to him, it didn't take long for Kyle to cum; he bucked a few times and cried out as his cock shot out rope after rope of semen into the ottter's foreskin. The amount causing the skin to balloon out some before breaking its seal and splattering the cum and pre mixture all over both of their groins. Corey had some experience he still had not cum yet, he's been saving his own load for something special, he wanted that sexy boy's ass. And the time was now for him to take his prize.

Kyle's mouth was wide open, gasping for breath after the greatest orgasm that he could remember. It was easy for Corey to slide 2 of his musky digits inside the humans mouth. The smaller male suckled on them, sliding his tongue between the webbings of his paw, lubricating them with his own saliva. The otter took his wet digits out of the humans mouth and slid them down the Kyle's backside, feeling the tight pucker between the male's asscheeks. He slowly slide a single digit inside; past the ring and testing out the depths of his passage, loosening it up some. Kyle's grip on Corey became much tighter, all four of his limbs clasped around the otter as his hole was penetrated.

The mustelid slipped in a second finger, both of them wiggling inside the humans anus, stretching it out further. He did want the human to enjoy himself after all, Kyle just seemed like he needed to let loose a bit, and what better way with sticking a few fingers in his partner's butt just before putting his own cock in? Corey was certainly no stranger to male-on-male sex, this cute little guy was lucky to be with such a considerable lover.

The giant otter decided that he had gone through enough prep work, it was time for the best part, he quickly pulled out his fingers from Kyle's hole, leaving the human a little empty, the otter had thick digits after all. But he was pulled as Corey stood up, holding the human closely to his muscular frame. That large dick was positioned just outside the human's anal ring, just touching it, leaving a string of precum connecting them.

"Hold on tight!" The otter exclaimed.

With a gentle thrust of his hips, the otter cock entered through the hole just above it. The head fully inserted, the foreskin pulled back some, allowing for a smoother invasion. Kyle cried out as he was penetrated, the was some slight pain, but Corey had been rather gentle, so the pain was soon overtaken by mind-numbing pleasure. He rested his head on the otter's broad shoulders as the large anthro holding him moved his dick inside him even more, almost to the base. Corey slowly crept his cock in even more to where the human holding on to him was feeling incredibly full. Never did his bowels ever feel like this, heat was radiating out from the member inside of him, giving him a warm, wonderful feeling. The otter made one last quick thrust before he was completely inside the human, balls slapping against those toned cheeks.

Kyle gave a happy sigh as the otter holding him gave a soft chuckle and gave him a slow and sensual lick up his cheek, tracing around the outline of his ear. Sending shivers down his spine. The otter smiled.

"Ready bro? Cause I do like to keep a fast pace."

Kyle nodded and braced himself, he was gonna enjoy this, Corey's experience gave him the time of his life inside this small, steamy room, and there was no way it was gonna end now. The large mustelid showed off his strength by pulling out of the human's anus, almost completely, the feeling of his foreskin rolling over his head sent tingles running through Corey's groin before he quickly shoved back inside the opened passage. True to his word, Corey maintained a quick and forceful pace as only an otter could, his hips clenching as he thrust inside and out of Kyle. Moving over to the wall to gain better leverage, the human was sandwiched between the moist wall of the sauna and the otter's large and sweat chest. Every time the otter pulled out, the human felt completely and utterly empty for a split second before he was rammed again with a loud squelch. The quick thrusts swing the heavy otter sack up against Kyle's groin. Just giving him an idea of whom was dominating him here, as if the previous cues weren't enough. His arms and legs almost going limp at the sensation overload. It didn't matter, Corey's arms were clasped around the smaller male's torso and the wall had supported him. Kyle was drooling, but it was lost in all the sweat that had surrounded them, all the perspiration that comes from an intense fuck in a sauna.

Corey's thrusts became more erratic, there was only so much stimulation that he could handle, and Kyle's bowels became tighter as his prostate was continuously jabbed. The human climaxed for a second time, spewing out just as big a load as the first, ropes of jizz landing over the mustelid's chest and his own.

The larger male felt the hole eating his cock spasm hard and tighten and this sent him over the edge. Large balls contracted and moved up into his groin as he grunted and came. Ropes of hot otter cum splashed inside of Kyle anus. Corey grabbed the smaller male into the proverbial bear hug as he continued to fire his load deep into his partner.

The otter's orgasm tapered off and his grip on the smaller male relented. The ordeal had been so much that Kyle had all but passed out from the intense fuck. Corey flashed his own killer smile and sloooowly_pulled out of his partner. A rush of cum followed his softening member as it came out with a _pop! His own otter dick had once again become covered by his foreskin, all covered in his own semen, as was the floor, splattered with the jizz that had only shortly been deposited in Kyle's swollen anus. Corey collected and licked Kyle's jizz from his chest, licking his lips.

He drapped a towel around the human's waist. In a firefighter's carry, brought the human to one of the relaxation rooms, it was cool enough here so the human would become hyperthermic, and quiet so he could stay until he woke up. Corey walked off to the locker rooms. Naked.

Some other of the anthros that were in the weight rooms earlier noticed the otter walk in.

The bull clapped the buff otter on the back: "Hey Corey! We saw that little guy walk off to the pool earlier. Hah! He couldn't take his eyes offa us!"

"Can't blame the squirt though, especially when he saw me flexing, size queen he is!" The horse butted in.

"Bet you had fun with him eh? Probably a virgin, sneaky bastard hogging him for yourself!" The Doberman jokingly scowled.

Corey was smug in his defense, "Hell yeah! At least I actually talked to the guy unlike you bozos, just thinking that he'll come up and just suck your dick. This is why I get a lot more ass than you at the clubs." The otter laughed.

"Well, when that cute little fucker wakes up, I may not get a virgin ass, can't complain about sloppy seconds!" The horse talked to his workout buddies. "Who's with me?"

The bull and Doberman both cheered, tents starting to form in the towels wrapped around their waists in anticipation.

Corey chuckled to himself as he got dressed, "Heh Kyle's gonna get a lot more than he ever hoped for."

"Ah well, I got a sweet piece of ass and he finally gets a real man."
