Slade (c) Diablosscar on FA

**WARNING: Gay Sex, Transformation, large male genitalia, big bulgy muscles and all that other stuff is in here! Should only be read by those 18, 21, or whatever the legal limit is in your area, and those that like this stuff!**

Slade sat impatiently on one side of the long boardroom table, taping his fingers on the glass top, the time already twenty minutes past when he was told to come. He had no idea why he had been asked to come here, the main headquarters of Raging Stallion Gyms and Supplements. Sure, he was a member of the gym, mostly because there just weren't any others that could afford to give insanely low memberships, and still feel clean and fresh. Of course, the supplements and stuff that Raging Stallion made were insanely expensive, but were the best of the best.

He looked around the walls, at the dozens of framed pictures, both of humans and anthros; massive bodybuilders flexing next to their most recent prize, Olympic weightlifters showing off their medals, referees holding up the arms of victorious wrestlers. All of them were labeled with name, date, and which particular product they used, a wall of success and profit.

Slade focused on one picture especially, that of a feline wrestler, with thick black hair that seemed almost like he stepped out of an anime comic, and sweat soaked white fur, holding a massive trophy. A weary smile of hard won triumph, and the unmistakable bulge of a fat cock and balls yearning for freedom in the rather tight and small speedo he was wearing, seemed so... perfect. Something from that picture really called to him, that the victorious feline in the picture could be himself... was him... the perfect muscular body of a strong, virile cat.

"Enjoying the display?" a male voice called, followed by the steady and heavy clip-clop of iron shod hooves on the marble floor that could only have belonged to an equine. A very large one at that.

"Ye...yes..." The human blushed, noticing then and there that his own jeans were straining from the thoughts that were running through his head. He did his best to cover himself up, when the horse at last reached the table, and took a set on the other side.

When Slade looked up at the horse, the hardon only got harder, much to his dismay. The horse in front of him, despite the efforts by his fancy Italian silk suit to contain the bulges and muscles, was the very definition of god-like. His arms were so massive they were, by default, pushed away from his body, while his pectorals pushed out farther from the rest of his body than should have been possible, the tree trunks that posed as legs stretching his suit with each step.

"I'm Mr. C., and I'm the owner of Raging Stallion," he grunted as he sat down, the chair creaking from the strain of the massive bulk that found its home. "And I would like to offer you a deal, Slade."

The young man looked over the massive stallion. "What do you mean?"

Mr. C. shuffled in his groaning chair. "Well, I have reports that you joined our freestyle wrestling league, and so far your record is," the horse paused and flipped through a notebook, "zero to 12."

Slade sighed. He was most likely being asked to leave. As much as he loved wrestling, first the scripted pro stuff, and then the newer freestyle, no holds barred play that suddenly came out of nowhere, he desperately wanted to be part of it. But he was too small, too scrawny, and too weak.

"Well, I'm here to give you a once in a lifetime chance to not only improve your record, but, perhaps, give you more than you ever wanted," the horse grinned, flashing pearly white teeth.

Slade's eyebrows went up in surprise. "What? Why would you want me and not someone better?"

Mr. C chuckled. "It's not so much your record, but the drive and ambition you exhibit. All the managers keep telling me that you stay to work out late, and do give it your all. Well, I think I can help you out, and in return, you might be able to help me later. I'll even be your own personal trainer, something that I don't offer to many people. Heck, I can even put you on our payroll, minimum and a half wage, doing some odd jobs around the gym. What do you say?"

Slade looked away, pondering his options. He could refuse, and continue losing all the time. Or, he could accept the offer, and get help and possibly get better. Heck, he could even get a decent job, one that would allow him to ditch his current burger flipping career.

He looked around at the room and all the pictures around him. He didn't want to become massive, but buff and strong enough to succeed in wrestling. Enough to look sexy and still seem kind of normal. But his eyes locked onto the picture of the cat on the wall, the exhausted, victorious cat. He wanted to be him.

"Alright, I'll do it," Slade said. Mr. C. grinned.

It had been a month since he met Mr. C., and, despite everything, Slade was feeling that he was getting nowhere. He had put only a slight amount of muscle, and the wrestling matches he had been in seemed more like walkovers for his opponent. The training, the working out, and the failures were really starting to weigh on him.

"Maybe this wasn't a good idea," Slade moaned as he collapsed onto a gym mat, his entire body dripping with sweat from the intense training, his chest heaving heavily to get oxygen through his body. The muscular horse watched on with his arms crossed over his massive chest, wearing a muscle shirt that could barely hold the massive fur covered body and a pair of shorts that hugged very muscle in his upper legs and, unabashedly, his groin. Although all he had been doing was guiding his charge, the heat of the gym was enough to make him start sweating as well, unleashing a musk that assaulted and overwhelmed Slade's senses.

"I never did say it would be easy, did I?" Mr. C. replied, looking down at the tired human. "Though, I have to agree that your progress isn't as great as I thought it would be. Maybe..."

Slade looked over, his breathing somewhat normal. "What?"

The equine scratched at his nose, the small movements of his arms enough to make them bulge out and show thick veins pop out of his skin and fur. "We are working on a new product, one to help those with problems building muscle, such as you, to do so. Also helps with agility, endurance and a host of other things. And we are almost ready for human testing."

Sitting up, the young man looked up at the horse. "Really? It sounds too much like steroids."

The horse chuckled. "I swear to God, it isn't. It's all made with stuff that is produced naturally, with nary a trace of industrially produced chemicals what so ever."

Slade was very sceptical, but at this point he was ready to try anything. The image of the wrestling feline back in the boardroom was ingrained in his memory, and he wanted to live up to that, in any way he could.

"Well, I guess it couldn't hurt," the young man nodded, knowing he had nothing to lose and everything to gain. "What do you need me to do?"

"Meet me in the locker rooms in five. I think you have done enough for today," the horse ordered, turning around, flaunting his tight bubble butt, the long silky black tail flipping itself out of the way just to show himself off. If Slade wasn't so tired, he most likely would have got a boner from the display, but as it was, he groaned, and got himself standing up, and walked to the change rooms.

When he arrived, he noticed that no one else was there, not even Mr. C. which didn't surprised Slade that much, partially because the horse seemed to be always late for one reason or another. The young man found his locker, and twirled the combination on it, opening the thin metal door.

When it was opened, he was surprised to see a white bottle sitting on the top shelf, with a note taped to it

Sorry I wasn _'__ t able to meet you; business call. This is the product I want you to try out, and when you see me next you can tell me what you think. Enjoy!_

Mr. C.

Slade took the bottle, which was about the size of a normal bottle of pain relief medicine, and full of pills which rattled as he tipped it over. In big red letters was "CATAOZONE," with instruction written on, instructing that only one a day be taken.

"That is weird," Slade thought, opening the bottle, wondering what good a single pill would do. When he finally took off the top an overwhelmingly strong and pungent musk filled his nostrils, almost making him choke. At this point, he was sure that anyone that smelled him would have thought he had been sexed up by horny, sweaty furs, which, though it hadn't happened yet, he secretly wished it would, especially his big, muscular equine coach, forcing those massive cock and balls into the human's face, drinking down the sweet cum...

Slade shook his head, and sighed, the smell going away after a short time. He had been so focused on his training, and in the past few weeks that he barely even had time to jack off, much less find a buddy that would want to do it with him. And it was really starting to get to him.

Slade looked back at the bottle, and shrugged. "Well, I guess now is the right time for a pill," he thought, dumping one of the white spheres into his hand, then tossed into his mouth and washed down with some water from his water bottle. He then threw it into his backpack, beside the pain relief pills he normally had. He thought for a moment how similar they looked, but shrugged.

He almost expected something to happen as soon as he swallowed them, but mentally slapped himself for the silly idea. He shook his head, and finished undressing, grabbing a towel from a nearby cart and walking to the showers attached to the locker room.

After a quick shower, he dressed, and left the gym, walking back to his apartment in a tired, pain filled haze. By the time he at last got into his apartment, his entire body felt like it was on fire. Dropping his backpack on the small table that he used, he reached in for some pain medicine, popping open the bottle and dry swallowing three pills, hoping that, and sleep would make the pain go away. In moments, he was in his room and flopped on his bed, hoping that it was true.

Slade groaned as he woke up the next morning, the heat that filled his body still smoldering in the background. But as he stretched, something didn't feel quite right. It was only when he heard his shirt rip as he reached behind his head that he was sure of it. Looking down then, Slade gasped.

He had muscles! Not very big ones, but his arms were undeniably bigger, as was his chest and calves, while his torso felt smaller. He could feel the muscles on his back shift, something he thought he would never have felt. He reached out a hand to his biceps, and squeezed, expecting it to give away. But, if anything, it was harder than steel, proving that overnight his musculature had improved greatly.

Standing up, and realizing that he gained a few inches in height as well, he could feel the power surge through his body as if a dam broke, flooding him with energy that he never knew he had. His groin began to stir, the blood and heat rushing to make his penis harden, gaining inches more than normal, until it stuck out a good nine inches from his body. His balls also felt heavier, swinging like wreaking balls underneath his manhood.

"Oh my God... those pills worked!" he thought with a grin, before dashing to the kitchen and looking through his bag for the bottle. The first bottle he pulled out was the pain relief stuff, and he set that aside and pulled the other one out. When he pulled it out and opened the top, Slade noticed that only one pill was left.

"Odd, I thought the thing was full before. Well... maybe I should take that one now," he shrugged, dumping one more into his hand, and popping it into his mouth. Now, to find clothes to fit, Slade thought as he prepared to show off his new body at Raging Stallion and its owner.

That morning when he walked into the gym he noticed that no one was there, which was surprising. Usually, an assortment of furs and humans were in here, working out, training, or admiring themselves in the mirrors that ringed the place. But he did notice Mr. C. with a clipboard in one hand, and a pen in the other, wearing a pair of sweats and a muscle shirt.

"So, I see you tried out the pills Slade," he said, scribbling something down. "How do you feel?"

"Great!" Slade grinned, pulling off a flexing pose that just a couple of days ago would have seemed silly.

The horse looked up, his face showing concern. "You followed the instructions, right?"

Slade nodded. "Yeah, but there was only two in the bottle. I had one last night, and took the other one this morning.

Mr. C. looked up. "Are you sure? There was supposed to be five in there."

Slade paused, and looked over. "Ohh... I might have taken some accidently, thinking they were pain pills."

"Oh shit," the horse exclaimed. "Each pill was supper concentrated, designed to slowly work over eight hours. But you taking more than what I said could have some... side effects."

"Like what?" Slade asked.

"Well, I guess we will soon find out," Mr. C. grinned, an almost sadistic look on his face. "Thought, you may want to sit down..."

"What?" Slade cried out, trembling, as the heat from yesterday suddenly rushing back at full force, making Slade cry out, doubling over in pain. He could almost feel every muscle in his body suddenly push out, doubling the gains that he made overnight in a few seconds, the shorts and t-shirt he wore suddenly ripping to shreds, displaying his new body for everyone to see. Only a jock strap, the only thing that he could find that held his newer, bigger cock and balls that he found that morning was still intact, but they were starting to strain from the sheer pressure put on it. While he still was a ways from bodybuilder level of development, he rivaled even the biggest wrestler he had to face now.

But now the change was going beyond simple muscle mass. Slade clutched the hardwood floor as his fingernails grew longer and sharper, digging deep gouges into the floor, before turning red. Thousands of tiny white hairs began to push out of his hand, creeping up his muscular arms until they reached his massive shoulders and spread over his chest like wildfire, consuming the pink flesh in a white inferno.

The fur began expanding down his legs, and up his head. Slade growled out as his nose and mouth pushed forward into a short feline muzzle, and his ears grew larger, more pointed, and shifted further up on his head, turning into miniature radar dishes. The pain in his head forced Slade to close his eyes and growl, but when they opened, they were no longer the familiar human eyes: his pupils turned into slits, and the former blue color around the iris turned a deep yellow, and allowed him to see even more than before. The changes to his face, such as a small black nose and long, nearly invisible whiskers, overloaded his senses with all the new information of everything around him.

The bones in his legs shifted into a digitigrade stance. His feet pushed out, destroying the shoes that, until that point, managed to hold together so well, sharp claws taking the place of toenails as it broadened out into paws, and his heel shifted upwards until it appeared that he was walking only on his tip-toes. From above his white furred ass which spread wider and showed the tight pucker in between the cheeks easier to whomever could see it, a long tail snaked out and casually whipped around, giving balance to the changing Slade.

His groin caught the flame then, his cock heating up and slowly pushing out even longer, gaining more length and width. The mushroom tip of Slade's junk began to grow dozens of short, sharp barbs, flaring out as his new erection surpassed a foot in length, and wider than a beer can. His testicles also grew larger, rivaling softballs in size, which became too much for the straining jock strap, and it at last snapped, leaving Slade naked for all to see.

The exhaustion from the transformation collapsed the new feline, breathing heavily as his entire body ached and tried to regain a sense of what just happened. Slade at last sat up, his muscles bulging with power and energy.

A strong scent wafted past his more sensitive nose, and a small chuckle was picked up by his ears.

"Well, that wasn't expected," Mr. C. remarked, setting down his clipboard and pen. "I knew we extracted the basis of the supplement from felines, but I never expected this to happen."

Slade warily smiled to the big horse. "At least I finally bulked up," he said, flexing an arm.

The stallion grinned. "And what are you going to do first with your new found strength and power?"

Slade sniffed the air again, the smell he got before suddenly registering on his mind. Standing up, Slade made his way to the stallion, before cupping the equine's groin, and squeezing the hefty orbs contained inside. "I think I have a good idea."

The horse grinned, wrapping his arms around the feline as Slade worked at removing the sweats from the stallion, half pulling, half ripping them off, showing that Mr. C. was going commando underneath. But removing the pants allowed the massive stallion's nuts, both the size of ripe cantaloupes, free, the sheath opening up and soon the thick horse meat spilled out, and grew larger and larger until it stood upright at an enormous two feet.

Slade was practilly drooling, and his long, rough tongue got to work, licking over every inch of the stallion phallus in front of him, while the equine snorted, and pushed the feline's face into his cock.

"You like that, don't ya kitty?" the horse said lowly, making the cat shiver. "You love licking my massive cock and balls, feeling the heat, smelling my musk."

"Oh yes," Slade mrowled, his massive paws playing with the balls while his tongue licked over all of the stallionhood he could reach. "Oh yes!"

Mr. C. grinned. "I bet you want them in you, as deep as they can go, stretching you wide, until I fill you up with all my seed."

Slade nearly fell over, his fondest dreams at last coming true. "Oh God... yes, I so want that!"

The horse laughed, as he picked up the feline and set him on the nearby bench, lifting Slade's legs up until his tight tailhole was visible, the long prehensile tail excitedly swishing back and forth.

The stallion lined up the flattened, broad head of his cock to the anal passages he was preparing to take, while Slade below, feeling the hot flesh at last push up, whimpered slightly as he realized what he was getting into.

"Oh god... you're huge," the feline moaned, trying to will himself to relax. Before Slade even felt that he was ready, the broad piece of stallion meat pushed in, the cock head stretching the anal ring as wide as it possibly go, and maybe even a bit beyond that. The shock and pain raced through Slade, making the feline cry out. But the pain diminished, but never completely went away, as the horse continued to push his massive log deeper into the unused ass. Inch after agonizing inch slipped deeper as Mr. C. grunted, using his strength to gain entry.

"You are...one of....the tightest... fucks I've...ever...had!" the horse snorted, thrusting his hips to push in more of his cock. Slade could only gasp and writhe as he felt his passage fill up as the rock hard wood forcefully entered him. But the feeling was divine, making Slade's already hard cock start to leak precum.

The transformed kitty began to push back in time with the horse's thrusts, making the horse's cock sink deeper, faster, into the tight hole .The thick medial ring popped in with a loud SLORP, and before either knew it, the last few inches were in, and the heavy horse sac smacked up against the feline rear.

"Oh my god," Slade groaned, his paws feeling at the large bulge his stomach made with the whole horse cock inside him. Mr. C. shivered as he could feel the thick paws massage his own dick through the furry flesh of the kitty he was inside, the reverberations also shaking Slade, and making him meowrl again in pleasure.

"that's just part one," Mr. C. grinned, and before Slade could say anything, the horse began to withdraw. Slade gasped and purred as the flared tip brushed up against his insides, making his barbed member leak out more of the thick, clear, sticky pre over his white fur covered abs.

At the half way point, Mr. C. suddenly lunged forward, his shaft quickly taking up the space it just vacated a moment before. Slade roared out in surprise, his ass clenching tight.

The horse nickered, and began to pull out again, quicker this time. "Now is the time for you to get the full meaning of horsepower!" With that, he thrust in again, Slade once again crying out, but already the stallion was building up a quick rhythm, his cock working like a piston in and out of the kitty as quick as it could, making Slade squirm, gasp and arch his back again and again as the long, thick cock abused his hole.

They had no idea how long it took, feeling like time had slowed if not stopped with the constant drilling of the equine into the feline. The pressure and tension built up was huge. By now Mr. C. was thrusting as quickly as he could, short pulls and thrusts of his mighty shaft and slaps of his churning full testicles spurring the stallion closer to his release. Slade, the rough handling of his rear and the heat rushing through him enough to edge him closer and closer.

"I'm... gonna...cum!" Slade cried, his entire body tensing up, and his cock shooting a huge load, arching high in the air and landing behind the two love makers. The second and third shot were as powerful, making a white stained puddle on the floor. The next few shots all decreased in power, a couple landing squarely on the feline's face.

The tight clamp on his cock forced the stallion to whinny out loud. A last thrust, a last slap, and the horse was hilted deep in the cat as his balls at last unleashed their bounty, massive shot after shot quickly filling the little area in the anus that was not taken up by the two foot cock, and then forcing the bulge in Slade's stomach to grow larger, pushing out his abs and stomach until he looked a few months pregnant.

The stallion pulled out before he finished though, the rest of his bountiful seed landing on the feline. Shot after shot from Mr. C. covered Slade, a one-man bukkake in action. By the time the last of the plentiful balls at last dribbled out, the feline was covered almost muzzle to foot paw in thick horse seed.

Slade lay on the bench panting heavily, rubbing the cum into his fur and feeling the large bulge in his belly. "You sure you're done? This has got to be like five or six guys!"

The horse chuckled, grabbing a nearby towel and wiping the sweat from his forehead. "Oh, I'm sure I can go another two or three rounds. But I'm not sure if you can handle it."

Slade pushed himself up, the cum soaked, cum inflated, cum hungry kitty's eyes flashing. "Only one way to find out." The stallion grinned.

The bell to the side dinged, and the crowd roared as the match drew to a close. Two fighters, only clad in tight speedos, were in the ring, one a thick bear with scratches and bruises all over himself lay on the mat unconscious. Above the defeated ursine stood a muscular white feline, with a mass of black hair that almost looked like it belonged on an anime character more than a bipedal cat. He was breathing heavily, and he also had bruises, and even some blood, on his body.

"And the winner of the Raging Stallion Gym and Supplements Free-Style Wrestling Championship is... Slade Tehkiteh!"

Slade lifted his arms in triumph, as the referee and Mr. C. handed a massive trophy to the wrestler, who then posed for pictures as journalists and fans jostled for the best view.

The massive horse in the tight designer suit felt his pocket vibrate, and he pulled out the cellphone, and looked at the text message that it just received

Congrats on your student winning. Deals are open to him from all branches of the conglomerate. Let us know when he will accept. The Boss.

Mr. C. chuckled, flipping the phone back down. Yes, being a small part of CIMIndustries had its perks, not only for the companies themselves, but also those like Slade that made one small part of it look really good. Slade was in for a life of product endorsement and wealth.

And, if the large bulge in Slade's speedo and the stirring in the stallions crotch was any indication, of gratuitous gay sex.
