\ **Fzzzzzzzzzzzzzzz* *

Felix smiled under the warm wash of the hot shower. After a long day of tennis practice his body ached and his legs were throbbing from over exertion. He smirked at the memory of how Coach had told him that he should be careful on the far reaching swings. But he was a bit of a showman, always wanting to take the more risky gambits for the sake of making the game more exciting.

He sighed as he reached over and grabbed a nearby bottle of shampoo; he squeezed the minty smelling soap into his hands and lathered it lightly before scrubbing it into his short black hair. There was a brief tingling and cooling sensation that hit his scalp for a brief moment before the warmth of the shower hit him again. He had always liked this particular brand, it always relaxed him and it kept his hair looking shiny and clean.

Suddenly then, the wet sound of footsteps on the shower tile floor echoed through the room and Felix turned to see a burly looking man walk in with a towel wrapped around his waist. He must have been a football player by the look of things, with his hair cut military style and his chest and arms bludging with muscle. He sported a bit of a gut though and a light dusting of red hair down his chest. Felix turned away and tried to focus on his shower. He didn't want to seem like some sort of homo for looking at him to long, and with these old fashioned showers, privacy was very minimal. Washing the remainder of the soap away, he reached down and grabbed his body wash. But just as he popped open the top; he heard a soft moan, followed by a low grumble from across the room.

"Fuck...." He heard the football player groan.

Felix paid it no mind and just started to wash himself, getting in all the small crevices of his modest build. He slowly began gently rubbing the sweat and grime from his clearly defined abdominal muscles and his modest pectorals. After he had properly lathered himself up, he stood back underneath the shower head and allowed the suds to be cleanly washed off.

"Nnnngh...." Moaned the football player again.

Felix scowled, wondering just what was going on as he turned his head to face the other man.

It would have seemed that the football player had gotten rid of his towel after he had stepped into the shower, which was understandable enough. However the fact that he was furiously beating his impossible looking 12 inch meat was something that was definitely not a common sight in these showers.

"Holy shit...Ummm, hey buddy, you mind not doing that here?" Felix stated, feeling slightly disgusted at the lewd action the other man was performing in the middle of a public shower.

The football player only grunted and ignored Felix, continuing to beat his meat like an animal, even going so far as to reach up and tweak his own nipples and kissing his flexed bicep.

Felix grumbled and resigned himself to get out of there as fast as he could. He still needed to put on conditioner, but at this point he could save it for later. Felix then quickly tried to scrub off any residual soap from off his body before he turned the shower head off and mad a grab for his towel.

He quickly made his way out the door, trying not to look at the football player as he continued to jack off. However out of the corner of his eye he thought he saw something unusual and he turned to face the footballer much to his displeasure.

The man grunted and moaned, pleasuring himself in any way he could as he beat himself off. However there was something strange about the man's cock, even though the flurry of strokes its owner was giving it, Felix would have sworn his shaft looked...darker than the rest of its owner, and it looked even longer than it had before.

But he just shrugged it off and went into the locker room, quickly trying to get himself dressed and out of there before the other man "finished".

After punching in his locker combination, he grabbed a towel and quickly dried himself off before getting his street clothes and shoes. The sound coming from the showers grew quiet as Felix fumbled to tie his shoes. Not wanting to have an awkward confrontation with the other man, he struggled to get his clothes on and get out of there as quickly as possible.

After some difficulty he was eventually able to make himself presentable. With one final adjustment to his shirt and pants he slammed his locker shut and made his way towards the door.

The sound of wet footsteps echoed through the locker room as Felix made his way past the first row of lockers. But just as he was about to reach the door he was suddenly stopped by large wall of flesh that leapt from one of the adjoining rows.

Felix staggered back slightly, dazed from the impact before he realized just what had happened.

Standing in front of him was the football player from earlier, still wet from the shower. But there was something seriously wrong with him. Standing tall and proudly out from between his legs was no human cock, it was something strange, massive and colored with bright pink and black splotches. The head was also very different, not the same rounded bell shape that he had sported before, but in a flared rim that seemed to throb with every beat of his heart.

"Hey, Whoa! What's going...on..."

Felix gawked at the sight before him and the man's monstrous cock. What he failed to also notice was the glazed look in the man's eyes and the white goo that hung to his lips.

"Holy shit! What the hell is wrong with you? Do you need a doctor or a nurse or... mmmmphhhh!"

Felix couldn't make out that last word as the massive football player suddenly grabbed the sides of his head and shoved his face down onto his cock. Felix tried to scream as his mouth was filled with the man's gigantic cock, but the footballer just shoved his face deeper down his dick as he began to thrust his hips slightly.

Felix squirmed under the massive man's grip, trying his best to break free by kicking and punching at his sides, but nothing seemed to have any effect. He could feel the shaft throbbing and swelling in his mouth and his taste-buds were assaulted by the musky pole. But Felix's squirming only seemed to drive the football player even further as he thrust his inhuman cock deeper down his throat as a stream of salty precum began to pour from the flared tip.

"Nnnngh....fffff....NEIGH!!!" the footballer cried out.

Suddenly Felix's cheeks were bulging from the deluge of cum that suddenly came from the other man's cock. It was thick, creamy and was in such a great quantity that it forced its way down Felix's throat.

One...two...five...ten...Felix lost count of how many times the cock throbbed in his mouth. He had nearly choked on the other mans seed, but reflexes told him to swallow early on, which may very well have saved his life.

But eventually, the footballers grip on his head loosened and he slowly backed away. Felix coughed as the man's monstrous member was removed from his mouth and left him with a salty taste on his lips.

Felix gasped for breath as he clenched onto his knees, feeling the urge to vomit, but with nothing coming out.

Suddenly, there was a loud thud, and Felix looked up to see the footballer had sat down onto a nearby bench, eyes shut and with a content smile on his lips as he drifted off to sleep.

"Hey...hhhaa....you....the fuck...." Felix wheezed out before suddenly he felt a tingle envelop his groin.

It first started out as a light tickle, almost like his groin had fallen asleep, but then suddenly the intensity increased, to a point where his cock and balls throbbed with need as they pressed against his shorts as his modest 6 inch member rose to attention.

Felix felt his body grow hot, like his entire body was burning. His clothes began to cling tightly to his body and the feeling of the fibers brushing against his skin seemed to only make the heat grow more intense. He quickly stripped off his shirt and pulled down his pants and underwear with one swift tug before he sat down on a nearby bench and gasped for breath as his body sweated profusely.

Felix sat there for only a few moments as his body went through another intense hot flash that had him gripping at the sides of the wooden bench. His skin tingled and his groin felt like it was on fire. He soon broke out into a cold sweat and his entire body tightened up as whatever was happening to him did its work. Felix tried to cry out but all he could make was a horse-like groan before he found himself out of breath. He sat like this for a few moments with his stomach churning before finally, as quickly as it came; the heat began to fade away. But just as Felix thought he could begin to relax, his entire body shivered and he let out an involuntary moan as his cock throbbed with need. His mind then began to grow muddled as his pleasure sensors were overloaded and he took his cock into his hand, wildly jacking off with little regard for his surroundings.

The pleasure grew more intense with each passing moment he jerked his pole, squeezing and teasing his shaft as it drooled a steady stream of precum onto his hand. He quickly increased his pace as a tingling enveloped his balls as they swirled with growing seed, jerking off faster and faster, letting the growing feeling in his balls build up higher and higher as he desperately tried to get off.

However, that wasn't the only thing that was growing at that point, in his grip with every stroke his member grew longer and thicker, his mushroom shaped tip flattening out and a strange ring forming around mid-way down his cock.

The flesh of his growing tube soon then began to darken, turning the lightly tanned shaft into a spire of pure ebony colored flesh that grew until it reached all the way up to his chest. His balls were no different either, growing and swelling from the size of grapes to the size of small oranges, their contents changing and shifting as they swelled in growth as they too turned a dark black color as a fold of skin began to grow along the base of his shaft.

Felix grunted and groaned, his cock becoming more sensitive by the second and his balls ready to burst. He could feel himself on the edge, but something just wouldn't let him pass it. He grunted in crazed frustration as he jerked himself off to any images he could think of. Busty women, swimsuit models, his favorite scenes from porn. Nothing seemed to work. But in a brief moment, he opened his eyes and saw the man in front of him. His body was massive, but soft, he sported a short red beard and he had a bit of fuzz along his arms and legs. But what he saw last was just what he needed. The cock that had just been shoved down his mouth only moments ago, that pink and black pole of maleness that had deposited a load straight into his stomach. That was it...

"Nnnnnngh...NEIGH!!!!!!!!!"

Felix cried out as his cock throbbed in his grip, shooting out a massive gush of thick, creamy spunk into the air. This was soon followed by another and another until the floor was practically painted with his cum.

After a few moments, Felix let out a sigh of relief, basking in the afterglow of his incredible orgasm before suddenly a wave of dizziness overtook him. The room begun to spin, the once distinct shapes of the locker room growing fuzzy until finally Felix leaned back onto the lockers and shut his eyes, drifting off to sleep as his changed cock slowly slipped into its new home

****Video Feed Skipping to Next Interaction. Time: 17:00****

The sound of murmuring echoed through the room.

"Shit, he got it too..."

"Shit, I can't wait till I get me one of those..."

Felix grumbled as he slowly opened his eyes, only to see that he was surrounded by two other guys his age. One stood at about 6'1 with a mop of long blonde hair and a short goatee around his chin and mouth. The other was a smaller man, standing at 5'3 but with a much stockier build than the taller blonde with a shaved head.

"The fuck happened to me...." Felix groaned

His vision then caught something dark in the corner of his eye and he looked down. A chill then ran down his spine and his eyes opened wide in shock as he stared down at the black, leathery sheathe he now sported in place of his own cock and balls.

"WHAT THE FUCK?!?!"

Felix jumped up onto his feet and pushed the other two back, sending them slamming against the lockers.

"Stay back! Stay back!" Felix shouted in a panic as he reached down to pull up his discarded shorts and underwear.

The two boys groaned as they took a step away from the lockers, rubbing the spots where the metal had hit them the hardest.

"Uuugh...don't you know man? You got that Acquired...Equine...thing." Stated the blonde as he tussled his own hair.

"Most people call it the STHC. Sexually Transmitted Horse Cock, and you my friend, have got yourself one hell of a dong to be proud of." Stated the shorter man with a cocky grin as he watched Felix fumble with his waistband as he tried to pull it over his enlarged sheathe.

Felix groaned and grunted, trying his best to pull his pants over his new equine appendage. But every time he tried to pull his pants up to hide it, he would end up squeezing his balls to tight. Too low and his sheathe poked up above the waistband and could be seen clearly through his t-shirt. After a few more tries Felix then eventually gave up, sitting back onto the bench with a groan as he looked down at his cock in despair.

"How could this happen to me..." Felix said, looking almost on the brink of tears.

"That's....actually my fault really..." stated the blonde.

The sound of a zipper being pulled down rang through the room and the jeans the taller blonde was wearing fell to the floor with a thud. Felix then looked up to see that the blonde sported a sheathe of his own, except his member was standing out of it slightly and colored mostly black, with a few pink splotches along the length.

"I see you met Richard...big lug knew I had a horse cock and he wanted one for himself. Looks like the big guy was packing a small wiener and wanted some male enhancement." Said the blonde with a cocky smirk as his cock slowly began to emerge, growing inch by inch with each passing moment.

"So I told him I would help him out, but only if he blew me for it. He was a bit against it at first, but straight boys are always the best cocksuckers. Must be from thinking about how they want their girls to do them...Anyway, Coach nearly caught us halfway through and I just had enough time to get off and stuff this monster back in my pants while he ran off." He finally stated just as his cock reached full mast, throbbing at about 14 inches and drooling a bit of pre onto the ground already.

"Ahhh...shit...now I gotta jack off again...looks like you're gonna get your turn after all Danny..." said the Blonde with a smirk as he gently gripped his member and rubbed his hand up and down his length.

The shorter man eyed the other man's cock with hunger as he licked his lips and placed a hand on the other man's member.

Felix just watched on in shock as the man known as Danny began to jack off the blonde with the horse cock. He would have normally been disgusted at the sight, but strangely he found himself getting turned on by the whole spectacle.

"Mmmmm....so anyway, you have a horse's cock too now. Just be careful where you point that thing, unless you want some other guys to start sprouting horse dongs of their own...nnngh.....fuck man..."

"I...I dunno what's happened...what will I do now, I'm just some kind of freak now..." Felix stated shakily as he continued to watch as the shorter man Danny slowly removed his shirt and pants, revealing his own erect and still human member to them all.

"It's not that bad...you'll cum heaps now, and who wouldn't want a dong this size?" The blonde then moaned as Danny leaned over and kissed the other man's equine member, peppering the length of the shaft with kisses as he made his way towards the tip.

"Only downside is I think this makes you gay...but I was already that before I got infected...Fuck man yea...." Danny smiled as he gripped onto the blonde's cock almost possessively before he opened his mouth wide and took in as much of the other man's meat as he could handle.

The Blonde then tilted his head back and moaned, gripping onto the back of Danny's head tightly and pushing him deeper down onto his cock. It was then at this moment, Felix noticed that there were two strange bumps emerging from the blonde's hair. These bumps then grew and grew, taking on a faint, triangle like-shape before they were covered in blonde hairs and began twitching around of their own will, taking in the sounds of the room and the sounds of the man below him who was enthusiastically sucking him off.

"Shit...neiiighaaaaaa...I'm not gonna last long if you do that...Anyway, my names Gerald. What's yours man?

"F...Felix..." He grunted, not even realizing that he had already begun to jack off.

"Well Felix...How about you go see what Richard's up to...then we can hose this slut down as he grows into his new meat?" Gerald said with a smirk.

Felix groaned as he felt a shiver shoot down his spine, all ending at the very base, where unknown to him, a small nub was beginning to grow.

"Sounds good..." Felix stated in a lust filled haze as he got up from off the bench, with his cock drooling pre down onto the floor below.

"Shit I'm getting close..."Gerald stated as he clenched his teeth and thrust his hips, feeling his balls churn one final time before they shot their load out through his massive member, and down into Danny's eager mouth.

"So how do we do this?" Felix stated as he squirmed slightly in his seat, his cheeks red in embarrassment and his cock threatening to burst from his pants at any moment.

"Just sit back, relax and enjoy yourself." Gerald said with a smile as he leaned back in their booth as he casually examined a menu in front of him.

After cleaning themselves up and welcoming another into their fold, Gerald had taken Felix to a diner across town and left the two footballers to enjoy their new appendages. It would have seemed that what he had said earlier about the disease making other guys gay was true. Not even a few minutes after he had woken up, Richard pounced on Danny and shoved his cock right into his mouth. Danny didn't seem to mind one bit though and was at full mast again in a matter of moments. They didn't stick around to watch them finish, but Felix could almost feel some sort of compulsion to join the two.

"The owner is one of us, and he lets guys like us hang out here and relax. Plus we get a few willing "converts" who come in for a taste of the good stuff." Gerald said lewdly as he adjusted his package through his shorts.

Felix nodded, although that didn't take the red from his cheeks. This whole situation was still very strange to him, especially with all these new feelings he had and the strange new attractions he felt to guys. But even though he remembered otherwise, the stirring in his groin he felt whenever he saw a hot guy pass by, or a guy with a large bludge came close was just the same he felt when he thought about girls. It wasn't some new and alien feeling, it was almost like he was just...adjusting to himself, almost like he had been sick for a bit and his senses were re-adjusting to the world around him.

One thing though he still hadn't gotten used to was how calm Gerald was about his new equine ears. From what he remembered hearing around school and on the news, the disease was supposed to just give people a horse's cock, not ears. He had also noticed how Gerald had been adjusting his shoes over the past hour, and he seemed to be constantly clenching and unclenching his hands. It was a worrying thought that was only compounded by the small lump he himself had found on his back earlier where his tailbone was.

Suddenly then a waiter began to approach, he was a fairly toned looking Asian kid with dark black hair and a bright smile. He was wearing a long apron as well as carrying a pad and paper. Felix thought he recognized him from school, but he couldn't think of his name.

"Hey there guys, what can I get you?" said the waiter with a soft smile.

"I'll have coffee, two sugars please" Gerald stated politely.

"Need any cream with that?" The waiter said with a cocky smirk as he adjusted his crotch lewdly right in front of them.

"No thanks, but maybe some later" Gerald said with a coy wink to the waiter.

The waiter smiled in response, then turned to Felix with the same sly grin.

"What about you?"

"Just water please...." Felix stated bluntly.

The waiter seemed almost disappointed at that remark, but he quickly put back on his grin and scribbled the order on his pad before walking away.

"Alex, he's the owner's son. Some say he got his cock from off his dad..." Gerald said with a grin as he re-adjusted himself one final time before he finally let out a sigh and Felix heard the sound of a zipper being undone.

"Ahhh...that's better...."

Felix heard a light thump and could only assume just what the other man had done.

"Specially designed pants or not. When your sporting wood you just gotta let the beast out, know what I'm saying?" Gerald said coyly as he leaned back casually.

The scent of horses and sweat soon began to waft from where Gerald was sitting, and it wasn't long until the smell hit Felix. His groin begun to stir and he could feel the fabric straining under the pressure. His cock was swelling up to a larger size than his pants could contain and it was beginning to hurt.

"Ohhh...better let that bad boy out. Looks like you've got it baaaad...." Gerald said almost mockingly as he leaned forward.

Felix squirmed in his seat, battling with the intense arousal and the growing pain in his groin. The tightness was beginning to become unbearable and he could almost hear the sound of the fibers of his jeans begin to tear. Felix moaned in pained pleasure as his cock throbbed in its tight confines, already leaking pre that was beginning to soak through his underwear and nearly through his pants.

"F...Fine...." Felix stated in a defeated tone as he quickly reached down and fumbled with his pants, undoing the zipper and button before pulling back the elastic of his boxer briefs.

The relief was like a breath of fresh air as his meat was let loose. He then quickly reached down and pulled his balls from their tight confines as well, letting out a sigh of relief as the pain had finally subsided.

"See? There ya go, not so bad now is it?"

Felix grumbled softly, but then he suddenly felt something touch his cock, something warm and wet. Gerald grinned at the sight as he reached down at his own pole again, directing his own flared tip to press against Felix's own.

Felix let out a soft moan, his body shivering in pleasure before he found the strength to compose himself.

"Cut that out!" he said with a low growl.

Gerald grinned and leaned back, giving Felix his space as he let out a relieved sigh and looked down at his own member and the height of the table.

"No need to worry man, most guys here are like us, and anyone else who shows up is just looking to join up...or will join up soon anyway." Gerald said with a sinister grin as he reached down and seemed to casually jerk himself off under the table.

Felix was about to say something in protest, but their waiter Alex soon returned with their drinks.

"My my...he's a big one." Said Alex with a lusty grin as he eyed just a small portion of Felix's cock from above the table.

"Yea, this footballer looking to join up ended up losing it in the showers. Since I was the one he was blowing, I felt like it was my duty to help him out. Get him used to things ya know?" Gerald said as he casually took the spoon from the side of the saucer and began to stir the coffee.

"Well, I gotta get me a taste of that sometime soon. Or maybe he would like some himself ..." Said the waiter coyly as he turned away, brushing aside his apron only for a moment to show his semi-hard equine maleness that was hanging freely from out of his pants.

Felix felt his cock throb at the sight and he could feel his balls churning in arousal. But Alex soon made his way to another table, but not without flashing Felix another sly grin.

"Shit...he's such a tease..." Felix suddenly found himself saying.

"Yea, but I think that's just a way he gets better tips. Never seen anyone ever tame him before...but he does spend a lot of time in the back if you know what I mean." Gerald chuckled softly to himself before taking a sip of the hot coffee before setting the beverage down.

The two of them sat there for a few more minutes, Gerald slowly drinking his coffee while Felix took the occasional sip from his water. The diner was fairly quiet that night with only a few other people sitting in booths on the other side. Felix started to feel uneasy after a while, as his own cock still had refused to go down after being stimulated. He could feel the lusty haze begin to rise in the back of his head again and his hand slowly began to drift down to his member.

*Ding!*

Gerald and Felix suddenly turned to see one guy walk in. He seemed a little older than them, possibly someone from the local University. He was powerfully built with his tight fitting short sleeved shirt straining with every movement and displaying his muscles proudly. He also had two tattoos on his exposed arms, a tribal tattoo snaking down one arm and three Greek letters down the other. This guy almost seemed like your garden variety frat boy, but he wasn't nearly as boisterous or loud as most of them normally where. He actually seemed a bit nervous as he wrung his hands together and looked around the room.

Gerald smiled as he caught the man's attention and beckoned him over. Felix watched cautiously as he approached, the massive man almost shivering as he walked over to their booth and sat down next to Gerald.

"H-hey there guys....is this place...you know?" he stated in a hushed whisper.

"Looking for some equine enhancement eh bud?" Gerald said smugly as he reached down and pulled his exposed meat to the side, giving the frat boy a full view of his fully erect shaft.

The frat boy gasped and recoiled at the sight. Before he shook his head and his features hardened slightly.

"Yea, that's why I'm here." He stated.

Gerald grinned as he let go of his cock, causing it to bump into Felix's member and exciting a moan from both of them.

"Nnngh...just so happens me and my friend here could both unwind. So I'll make you a deal. My friend here gets your mouth and you can have my hole. Once you're sporting your own horse cock, then we both get your hole. Sound good?" Gerald said with a lewd grin.

Felix felt his body shiver at the thought of a chance at the musclebound hunk. His urges were becoming more and more powerful and he could feel himself ready to burst at any moment. He needed to get off and at this point he didn't care if he used to think he was straight, he NEEDED to blow his load.

The frat boy seemed to hesitate for a moment, seeming unsure of what he should do. But then he let out a low sigh and nodded to the both of them.

"Right, ok I'll do it..." He stated with an assured nod.

Felix and Gerald both smiled as they got up from their both, their shafts standing out proudly as Gerald led them to what seemed like a bathroom. The frat boy stepped inside first as Gerald opened the door and led the two of them inside.

The smell of sex and equine pheromones hit them all like a ton of bricks as they got inside, Gerald and Felix both shivered as their equine man hoods throbbed in anticipation and began to leak a steady stream of pre down onto the floor. There were signs of sex everywhere, with tattered clothes scattered around and the scent of sex hanging heavy in the air. From all appearances, it seemed to be a recently converted bathroom where three empty beds sat side by side...with surprisingly clean looking sheets.

"Mmmm....owner keeps up with the place..." Gerald muttered as he noticed Felix's obvious curiosity as he dropped his pants, letting his massive cock hang free. The black and pink mottled shaft had already reached its full length of 14 inches and was slicked with a steady stream of pre. Gerald quickly got onto one of the beds and smiled smugly as he lifted his legs slightly and gave the two boys a clear view of his hole. Felix had to fight back the urge to jump onto him right then and there, but soon the towering physique of the frat boy blocked his view as he stood in front of him. The frat boy let out an approving "mmmmm" before he peeled off his shirt and dropped his pants in two quick movements. Felix practically drooled at the sight of the man's perfectly toned butt as he climbed on top of the sheets and lay next to Gerald. Felix soon stripped as well, letting his massive ebony spire of flesh loose as he climbed next to Gerald as the other two were exploring each others bodies. Gerald was slowly tracing his fingers along the outline of the built man's abdominal muscles while the other man experimentally gripped onto Gerald's cock and gave it a slight tug.

"Oh! Ohhhh....mmmm...you really want this don't you stud?" Gerald said with an excited moan as the man slowly began to jerk him off.

"More than anything..." the man whispered softly as he reached down and licked Gerald's shaft, causing him to moan in pleasure as he gripped onto the sheets of his bed.

Felix shuddered at the sight and took his own cock into his hand and began slowly jerking off, coating his hand in a layer of his own pre as he lubricated his shaft.

"Ohh...you got a name?" Gerald suddenly asked, seeming to try to keep the pleasure going as long as he could as his changed ears twitched atop his head and his legs began to flex instinctively.

"Nick. Nick Solar." He stated before reaching down to give Gerald's cock another lick.

"Well Nick...don't forget about our friend here...." Gerald said as he looked over to Felix with a lewd grin.

Felix smiled back as the jock climbed over both of them and moved over to Felix's side. Nick soon took Felix's cock in hand and began slowly jerking him off, sending shivers down the young man's spine.

"Fuck your big...bigger than any I've seen." Nick stated in admiration as he leaned down and licked Felix's shaft, causing the two of them to shiver in pleasure.

"My boy here got his from a guy I gave it to. He's one prime stud isn't he?" Gerald said with a smile as he reached over and tweaked Felix's nipples slightly, causing him to moan in delight as he bucked his hips upwards.

"Damn right...hope mine gets to be just as big." Nick stated before he leaned up and opened his mouth wide, taking in the tip of Felix's flared member in one go.

Felix let out a loud moan as the other man's expert tongue began hitting him in all the right spots. He could feel his balls churning and he knew that if Nick kept this up, he wouldn't last for very long.

"Fuck yea..." Gerald stated as he jerked off while Nick began to blow Felix, his own equine member swelling in size as he watched the lewd act before him.

As Gerald watched however, a strange change began to befall him. His feet began slowly shifting into a strange, more rounded shape as the skin turned a dark black, hardening with each passing moment as they began to swell in size as each toe began to merge into the growing mass. Gerald let out a pleased nicker as his chest then began to swell as he continued to work his meat, his pectorals increasing in size as the rest of his body began to fill out with more and more muscle.

Felix seemed to be going in a different direction while the musclebound Nick did everything he could to get him off. Had he not been so distracted by the amazing blowjob he was receiving, he would have noticed the increasing soreness coming from the lump that had appeared above his ass earlier that day.

Long, black hairs quickly began to grow from the growth, snaking their way out from underneath him as they grew until finally he was sporting a long and flowing tail. Soon after, small patches of the same colored hair began appearing all over his body. But these hairs were much shorter and compact than the ones growing out of his new tail. As more and more of it continued to spread, the layer of skin underneath became tougher, almost to a leathery-like hide texture as his pelt began to come in.

Gerald seemed to be growing a bit uncomfortable however as time went on. His changes seemed to be more radical than Felix's and he was beginning to look less and less like a human by the moment. His feet at that point had completely turned into a solid pair of hooves and his legs had swollen to a massive and inhuman size. He had even grown his own tail, with the same dirty blonde hair that he sported on his head now sprouting above his ass.

"Fuuuuckkk." He moaned as his cock flexed in his grip, swelling even larger than before as it began to curve even closer to his body.

His chest began to heave with each breath as it expanded outward changing his anatomy from within and re-positioning his arms as a caramel brown pelt began covering every inch of his exposed flesh like a rapidly spreading wildfire. Gerald's grunts and moans of pleasure then started to sound more bestial as the changes wracked his body, causing him to nicker and neigh with every wave of pleasure that washed over him.

Soon, a light popping sound rang through the room as Gerald's ribs grew out, giving him a more barrel-like shape as the fur began to creep down his arms and towards his hands. The same numbness that had overtaken his feet was beginning to wrack his hands as he slowly began to lose feeling in the individual digits.

"Ohhhh...fuck...ohh fuck...nnnnneigh!!!!" Cried out Felix.

Felix clenched onto the bed sheets tightly as he felt himself nearly loose it as Nick continued to work his pole for all it was worth. The other man was determined, and Felix could see the look in his eye every so often when he bobbed his head halfway-down his massive cock and slowly worked his way back up. He_REALLY_wanted him to get off and Felix felt like he wouldn't have much of a choice in the matter. But still, somewhere deep inside Felix a small part of him still not wanting to give in as his thick black pelt grew in across his body. As the fur reached down his legs, a ring of white hairs formed above his ankle and lengthened until they nearly touched the soles of his feet. However, this would not last for long as his feet grew out as his individual digits of his toes were pulled into his feet, merging together into a solid mass as it turned darker and more solid.

"Shit....I'm gonna...I'm gonna..." moaned Felix as he felt his balls churn and his cock throb in need.

This only seemed to drive Nick on further as he attempted to take in more of Felix's cock, causing another jolt of pleasure to wrack Felix, which only accelerated the changes in his feet as they solidified into a pair of hooves.

"NNnnngh....fuccccc.....NNNNNNNNNEIGH!!!!!!"

Felix involuntarily flexed as his cock let loose a massively pent up load directly down into Nicks eager mouth. The massive man was ready though and took that first volley and swallowed every drop. But with each re-occurring shot of his potent seed, he was only able to take in so much with each gulp until finally he was forced to reel back, taking his mouth off Felix's equine member as it continued to fire another burst of seed, coating Nicks chest several more times before it finally stopped.

"Hahhh....hahhhh...." Felix panted as the afterglow hit him and he was forced to lay back down to catch his breath, his cock already beginning to grow soft and slip back into its sheathe.

"Damn...." Nick muttered as he licked his lips and slowly began to rub the lost seed onto his chest, smearing it over his defined pectorals and giving them a shiny gloss.

\ **Whinny!!* *

Both Nick and Felix then turned their heads and remembered that Gerald was also there as well...however he looked very different than before.

At some point, Gerald had rolled off the bed and down onto the floor. His body seemed warped, his ass having grown to a massive size in comparison to the rest of his body. His cock seemed even bigger than before, bobbing up and down and slapping his flanks with a full 18 inches of horsemeat with each thrust he made into the air. But it seemed the rest of his body was beginning to quickly compensate for the rest of him. As Gerald's new tail swished about, his chest grew out and his shoulders began to grow less defined as they melded into his body, giving him a quadrupedal stance. Gerald's face also seemed slightly changed, his face growing outwards as his nostrils flared. Felix and Nick were both taken aback by all this, but Gerald seemed to have a look of pure pleasure plastered across his face as it grew longer and less-human. Nick and Felix could only watch as the final changes hit Gerald as a long and handsome looking mane grew in as his head and neck lengthened out further and further, until finally with one loud *SNAP* Gerald's arms and neck moved into place and he let out a loud whinny as his massive cock flexed and he sprayed a thick load of potent seed all over the ground.

"Whoa...hey buddy are you still there? I never...urk!" Stated Nick before he let out a gasp for breath.

Felix looked over to see Nick hunched over in pain, beads of sweat pouring from his brow and his member flexing involuntarily as it rested on Felix's leg. Staggering, Nick got up and looked down at his member as it began to change. The pink and fleshy coloration of his shaft growing darker and turning a light caramel brown with each passing moment. After he got over the initial wave of heat, Felix saw Nick's expression turn to an almost manic grin. He seemed almost giddy with excitement as he looked down at his rapidly changing cock as it grew longer and thicker every second. But then, Felix noticed the change in his eyes eye as Nick he looked up from his cock and towards the completely equine Gerald.

Even as he changed, he slowly staggered towards Gerald, who seemed to only just come out of his own lust-fuled haze to see the massive man approaching him with a rapidly changing cock. He let out a confused nicker for a brief moment; before his eyes seemed to roll back slightly as he snorted, letting the pheromones of the room hit his new equine lungs. Gerald then bobbed his head and smiled a goofy looking grin as he turned around with his four new hooves and flagged his tail upwards, showing a much larger and puckered equine hole to his potential partners.

Felix sat up and watched as Gerald stepped back and got near the bed just as Nick climbed back on. Now at a more suitable height, Nick positioned his cock right at the entrance to Gerald's feral hole just before he began to slowly slide it in.

Nick let out a pleasured moan and Gerald seemed to nicker in approval as Nick slipped his cock deep inside of him. Soon then, after the two had found a comfortable position, Nick slipped his cock out, slowly and sensually before he pushed himself back in.

The two of them seemed lost in the moment, both of them getting used to their changing bodies as Nick's cock continued to grow and Gerald became more accustomed to his new shape.

Felix watched on as Nick began to pick up the pace, thrusting faster and faster as his cock grew from within Gerald. He felt that last bit of hesitation he had held onto so tightly beginning to surface as he watched a man fuck a horse. But then, his own cock began to grow in direct denial of that feeling. Even after having recently spending his own load, he could feel himself growing hard again. The whole spectacle turning him on at some primal level. Felix watched as Nick's thrusts became longer and more enjoyable. He could even see the man's balls change right before his eyes as they swelled in size and with seed. Gerald seemed to be enjoying himself as well, grunting like a rutting animal as his head bobbed with each thrust and his cock slapped against his flank, hard once again and ready to shoot another load.

That little piece of resistance was beginning to waver in the back of Felix's mind, some instinct told him to run, to not be turned on by this, but the growing pleasure coming from his groin was beginning to overwhelm that thought. The sight of those two fucking like animals beginning to ingrain into his memory until finally, like a sudden gust of wind, that little piece of his old self was gone.

"Fuck that's hot...." Felix muttered.

Nick let out a loud moan as he gave Gerald another powerful thrust and Gerald nickered in response. Unknown to Nick at that time though, a small nub began to grow from the base of his spine, and his ears began to migrate to the top of his head. That nub began to grow out further and further, longer than what Felix's and Gerald's had grown to as a small bush of brown hairs began to sprout from the tip. His ears seemed to follow the same trend as they reached the top of his head, growing longer than the others as they were covered with a coating of brown fur.

"Ohhh...fuck I'm getting close...Ohhh hawww...."

Nick thrust into Gerald one more time, his new tail lashing about as a crest of brown fur sprouted across his chest and back, spreading across it and outlining each and every curvature of his massive build perfectly. As the pelt began to reach his legs, his knees began to bend slightly as his feet underwent the same transformation of the other two men in the room, growing more solid and dense with each moment until they were a pair of hooves.

"Haaaa...he-hawww...haaaa..." Nick moaned, the fur covering most of his body at that point and working its way up the sides of his face.

But then, Felix decided to join in on the fun as he got up from off the bed. His legs wobbled slightly as he suddenly realized his new changes. He looked down and around at his changed body, remarking at his dark pelt and his long and flowing tail. He could begin to feel a slight mane growing down his back, and his ears felt slightly funny at that time. Probably not having reached the same level as the other two boys.

But that did not frighten him, in fact, he relished in the changes as he made his way underneath Gerald, remarking at how much bigger the other man's cock had become after turning into a prime stud. Felix licked his lips as he took the horses cock into his hand and began peppering the length of the massive shaft with kisses just as the changes began to finally hit his upper body.

Felix savored the taste of the feral horse's musky shaft, licking along the length of the fleshy pole and tasting the precum he was leaking onto the floor below. He then gripped onto Gerald's cock slightly and jerked off the horse slowly, exciting a pleased nicker from the massive equine above him. Felix then opened his mouth and took in as much of Gerald's cock as he could, suckling earnestly as he reached down and jerked off his own equine maleness.

It was then; the final pieces began to fall into place for Felix's transformation. He went temporarily deaf for a brief moment as his new ears reached the top of his head, twitching and shifting with the sounds of sex in the room coming from different sides. The fur that was working its way down his arms finally reached his hands, but instead of turning into full hooves as they had done with Gerald, the coloration suddenly shifted to the same brown fur that had sprouted above his hooves and covered his hands entirely, leaving his digits intact. However, there were some slight changes, causing his fingers to grow slightly and his fingernails to darken and turn black, almost to the same shade as the new hooves he now sported.

"Hawwwww.....I'm gonna cum...hawww...." Nick brayed from above the two of them.

After such a short amount of time, Nick had changed far more rapidly than the other two had. His body was now completely covered in brown fur, and his face had lengthened out into a large equine muzzle. However he seemed to keep his hands and upward body positioning like Felix had. But instead of a horse, Nick had turned into some sort of hybridized cross between a man and donkey.

The changed man began to thrust faster and faster, ramming his hips into Gerald who whinnied in response as his cock throbbing in Felix's changing mouth. Finally, after a few more powerful thrusts, Nick let out a loud bray as he slammed his cock as far into Gerald as it could go as he let loose his load deep inside of him. This sparked a chain reaction in Gerald as he let out a loud whinny of his own and his cock flexed inside of Felix's changing maw.

Bones began to shift in Felix's face, lengthening out slightly as his mane grew in fully and his nose formed into a proper equine snout. Felix could feel the seed as it rushed forth from Gerald's cock, but he was ready for it.

Felix then quickly broke off from Gerald's cock, putting himself directly in the line of fire as he worked his own pole like mad. Soon then he was hit with a gush of Gerald's seed, followed by another and another as his chest was coated. He had even opened his changed muzzle slightly so that he could gain a taste of that potent seed that had inadvertently sired his new form.

Then, as he felt the warm goo begin to slip down the sides of his body, Felix felt his body flex and he let out a moan of pleasure.

"Ohhh fuck...oh fuck....nnnnnnghhh NEIGHHHH!!!!!!" he cried out as his cock flexed in his grip, shooting out a gush of seed that arched upwards and hit Gerald's chest, before another fired upwards and hit Felix as well. Followed by another, and another, and another until his balls had been completely drained.

The three changed men all panted and basked in the afterglow of their passionate lovemaking. Their body's all beginning to feel the strain of their changes as they felt their eyelids grow heavy.

Gerald moved first, letting Nicks' cock which had impaled him only moments ago slip out and let loose some of the seed that had been deposited into him. The newly feral horse made his way to the back of the bed, sitting down and re-adjusting his legs until he reached a comfortable position. The bed creaked in response, but the frame continued to hold regardless. Nick then reached down and offered a hand to Felix. Both of them coated in seed and smiling as they lay down on the bed, their heads resting on Gerald's large chest.

Then, the three of them slowly bean to drift off to sleep...none of them realising the sets of eyes that were watching them from a crack in the door....

****Report Log Date, December 18th, 2015****

No one quite knows where it first started, nor do they know who or what was responsible. But on November 16 th 2014, in schools, homes and workplaces around the world, a radical change overtook a large number of the male population of the United States.

** ** They called it Acquired Equine Genital Syndrome; Officially codenamed as AGES. This was a fitting title considering how the virus only seemed to affect those between the ages of 18 and 55.

The symptoms would begin with an intense heat enveloping the groin, followed by the subjects mind being overwhelmed with endorphins, causing confusion, disorientation and arousal. Immediately after the initial rush of dopamine, the subject's body temperature rises at a rapid pace, prompting the infected male to find any way of cooling off that they can. Studies have shown that there seems to be a re-occurring trend where subjects first rid themselves of any clothing they may have on at the time in an effort to cool down. The reasoning behind this is unknown.

After an initial transitional period, the virus then begins its next phase of infection. The virus rapidly mutates the host subject's cells, commanding the body's cell production to go into overdrive and re-wiring neural patterns in the host's body as it prepares itself for the final phase.

Not much else is known about what happens next, but eventually the male subject's penis then begins a radical transformation. Seeming to defy all known laws of matter and what we may know about biology, it grows and transforms into that of an equine shape. After which the subject is normally compelled to orgasm and will pass out.

After some rest, the subject normally will awaken with no memory of the event, and understandably would show some shock to their transformed genitals. However, that shock can quickly turn to curiosity, which is followed by lust, which then leads to the subject seeking out sexual gratification in any way they can find it.

There also seems to be a variety of what type of penis the subject will gain during their change, as some have shown variations in length, thickness and potentially even species when cross referenced with examples of other equine anatomy. However the reason behind this variation is still not completely understood and has currently been chalked down as a potential level of immune response each person's body may have to the virus.

In terms of how far the virus has spread, the number of infected patients at each location has sadly varied from either a small breakout to a full blown infection of every male within the premises. It would seem that the virus can also be transmitted to others through sexual contact or through ingesting infected sperm. To make matters worse, the outbreaks were so numerous and scattered that quarantine would prove to be ineffective. Thankfully the infected normally regain their senses after the initial "transition" period and can continue on with their normal lives with only minor issues.

However, as word got out a witch hunt soon began for those who had been infected, resulting in casualties and other such actions too gruesome to list in this report. So in an attempt to keep the peace, the president quickly publicly acknowledged the disease as a threat to the country. He explained what was known at the time and offered his condolences to those whom had been affected. He then declared that this new disease to be classified as a new type of STD, and advised all people from coming into sexual contact with anyone whom has the disease.

Geneticists, Scientists and Doctors from all branches of science have been working on a cure ever sense. The virus shows a particularly strong level of adaptability and can mutate at a rapid pace. Some scientists theorise that a new strain may even develop within the coming weeks. But that information is kept strictly confidential.

There is a storm brewing however as neighbours look at each other with suspicion and people refuse to even use public restrooms. Tensions are high and the people want answers to the big questions.

Namely, where did this virus come from?

The monitor continued to shine a dim glow as two figures stood near the monitor in the dimly lit room. Their features were obscured save for their larger body shapes and the suits the two of them wore.

"Well, that went about as well as expected." Said the man at the keyboard.

"Hey, seems like that little accident of mine turned into something interesting after all!" said the second man as he turned away from the monitor and smiled, adjusting his fedora slightly before he reached into his pocket and pulled out a strangely engraved golden pocket watch.

The man at the keyboard smirked, typing in a few more commands before the terminal shut down.

"Yes, let's just be glad that the good doctor decided to unleash his "male enhancement" virus and not his "horrifying flesh eating virus" instead. I can't imagine how bad the clean-up on that one would be. "

The second man only shrugged and he checked the time before putting the watch back into his pocket.

"Hey, CIMIndustries likes for its employees to work in multiple fields. I still think it was a good idea to put him in the genetic modifications and biochemical research department." Said the second man as he walked across the room, the tiles on the floor making a resounding "clop" with each step until he made his way to a nearby wall.

The second man paused for a few moments, petting down the wall until finally he reached what he was looking for.

*click!*

Light began to flood the room and suddenly it was clear who the two men where.

The one closest to the computer was a brown horse with bright blonde hair. He appeared to be a mix of two breeds and had a white streak on his snout and a short goatee.

"Yes, because unleashing an uncontrolled virus on an unsuspecting civilization is always a good thing. You're lucky me and The Director had some dirt on the president and several other world leaders. Otherwise this could have ended badly." Said the blonde horse with a sour face.

The other man was a horse as well, although slightly smaller than the other stallion with brown hair and a similarly colored pelt. He sported a black suit and a stylish looking fedora that had been made to allow his two ears freedom of movement.

"Well still, I think I can chalk this one up as a success for my company! Let's see your precious Conglomerate manage to pull off something like that!" said the brown haired horse with a grin.

The blonde haired horse groaned lightly before he broke out into a slight smile.

"Ever the proud one eh Cimm?" stated the blonde with a smirk.

"Hey, you know what they say, make every weakness into a strength!" stated Cimm with a smile.

"Anyway, so was that it Zeem? I expected your conglomerate to be much more thorough than that. I mean just one sex scene? I'm honestly a little disappointed." Stated Cimm with a cocky grin.

"Ohh there's more. Just thought that was a good stopping point. But we got files on nearly a dozen other guys. One's a gym teacher who ends up infecting his team, there's another who's some famous actor who turns an entire cast, and there is even one guy who taints the holy water at a church!"

"HA!" Cimm exclaimed.

"But I think that will be enough for now. I'm already a little riled up as is..." stated Zeem with a lusty grin as he reached down to adjust his formal pants, which showed a clear outline of a massive and erect member.

"Maybe some more later then. I mean there really is no such thing as too much horse cock..." stated Cimm with a smirk as he adjusted himself, with his pants bulging in a similar way.

"Maybe later...but now I better go "report" back to The Director" Zeem stated as he got up from the keyboard and switched off the lights.
