Chapter 1

Tom was focused on his breathing as he pumped the barbell up and down in a bench press. Sweat was beading over his fair skinned body as he flexed his well toned yet flexible arms. Since he was alone he hadn’t bothered to wear a shirt. The barbell piercings in his nipples caught the light and glinted as he moved. Tom was fond of his otter-built body and worked to maintain his healthy physique.

With a soft grunt Tom dropped the bar onto the rest on the bench. He sat up, wiping his hands and face with a small towel as his green eyes looked over his private gym. Though, calling it a gym would be generous. Half the time it was just the living room of Tom’s small apartment. Still, it had the core equipment he needed to keep his body fit and in shape. When not in use the equipment was pushed out of the way against a wall.

Tom idly scratched the close cropped hair on the side of his head. A quick inspection showed that the moderately sized mohawk had remained intact through his workout so far. The young man drained what was left in his water bottle, but felt far from refreshed.

One of the advantages of his living room gym was easy access to his kitchen. Tom pulled out a cold bottle of water from the fridge and started to drink. The cool water felt good, but he felt a rumbling in his gut and just knew he needed to put something in it. Tom was contemplating his choices when he remembered what had arrived yesterday in the mail. Unsurprisingly, he was on a few mailing lists for fitness and nutrition. Most of it was just junk mail, but Tom had received a free sample of some brand new supplement shake the other day. He wasn’t one to just throw out a free sample, even if he had no intentions of ever buying the product. Tom found the foil packet right where he had left it on the counter.

He picked it up and gave it a more in depth look than he had when it arrived. It was called Power Draft and featured the silhouette of a horse rearing up and the tagline of: Release your inner stallion! The company producing it must be new, because Tom had never heard of Epona Products Limited. He gave the nutritional information a quick glance then shrugged his shoulders.

It’s as good a time as any to give it a try. He thought as he pulled down his shaker cup from the cabinet.

He smirked slightly at the branding one more time before flipping it over to read the directions. It recommended milk or milk substitute instead of water, which was fine by Tom. He poured in the indicated amount of milk and tore open the foil package to pour in the slightly off-white powder. In short order he was shaking up the Power Draft. As he shook the container Tom noticed it was really getting thick, far more than the other protein shakes he had mixed up in the past.

Maybe I should have added some extra milk? Oh well. Tom popped the top on the shaker and took a sniff. What is that…

Based on his previous experiences, Tom had expected some kind of an artificial vanilla flavor from the color but this wasn’t anything like that. It wasn’t bad by any means, so he took a sip. He smacked his lips and he analyzed the flavor.

Is that apple? Yeah, and something else… he took another larger sip this time. Carrot? Yeah, it’s apples and carrots…That’s an odd choice, not bad though.

He smiled slightly. It was a welcome change from the usual vanilla and chocolate flavors of protein shakes. Tom quickly started to down the thick and creamy shake. It was by far the best tasting one he had ever tried. Before long he was wiping his mouth with the back of his hand. Tom's stomach was no longer complaining, and he didn’t feel overly full. In fact, he felt recharged, almost as if he had just started his workout.

Tom quickly rinsed out the shaker in the sink before returning to his weights. Since it was already set up, he decided to do a few more reps of the bench press. Tom got in position under the bar and lifted it easily off the hooks and down to his chest. It felt like it was his first set of reps as he pumped the weighted bar up and down.

Man just what was in that stuff? Tom thought as he ended the set and placed the bar back on the hooks. I don’t want to hurt myself, But I feel like I could do my entire routine a second time. Inner stallion indeed. He smirked to himself.

Tom sat up on the bench, taking a moment before moving onto the next exercise in his routine. He felt a slight itch just above his right thigh and slowly scratched it. He didn’t give it any thought until a similar itch began above his left thigh. He looked down as he scratched through his shorts. It was then his hand brushed against something.

The hell? Tom raised a blond eyebrow.

He ran his hand over the spot and felt something under his shorts, a bump that wasn’t there when he got changed for his workout. Tom quickly stood up and pushed down his shorts, leaving him in just a jockstrap. Right where he had been scratching he saw two large bumps starting to form. As he inspected them Tom could swear they were growing bigger.

Is this some kind of reaction? He glanced back to the kitchen where he had left the used package of Power Draft on the counter. It doesn't look like a rash…Did it just twitch? No, it couldn't, it must have just been a muscle twitch or something…

Tom gently poked the growth with a finger. There was no doubt about it, it twitched in response. He could feel it move, whatever it was, it was a part of him. The itching sensation had faded, but it was hard to describe how it felt now. It was a pulsing sensation, as if Tom could feel it growing larger with each pulse. Radiating out from the pair of strange growths a weird tingling sensation spread all across Tom’s lower body from his waist line down to his toes. Caught off guard by the new sensation, he fell back onto the weight bench, his bare rear smacking against the padded vinyl seat.

The tingling sensation made him curl and flex his toes, almost as if they were going numb from a lack of circulation. Tom was unsure what to do. He wasn’t in pain, but his entire lower body felt strange. As he debated on whether to call for an ambulance, the growths started to slowly push out from his body. Tom stared with his mouth open as they started to take shape. At first they looked like small fingers, curling and uncurling as they grew. Tom touched them nervously, not believing his eyes at this point. He could feel the tiny limb, and it could in turn feel his finger.

As his heart pounded in his chest, the limbs seemed to grow with every beat. It soon became apparent they were not fingers. A hard nub formed at the tip and they would sporadically kick out as they matured. Before Tom could decide what exactly it was growing out of his body, other changes started below his waist. He was instantly aware his cock was going erect as it pushed uncomfortably against his jockstrap.

“Now is not the time…” he muttered to himself as he looked down.

He could see the outline of his Prince Albert piercing straining against the material. That wasn’t too surprising, it was, however, surprising when his member continued to grow, pushing its way up to peak out above the waist band. Tom blinked, but suddenly became aware it wasn’t only his shaft that was growing as he began to feel an uncomfortable pressure around his balls. Tom groaned as he worked to free his manhood from the suddenly too small jockstrap.

He let out a long sigh of relief before he took in the scope of the growth. Tom was never one to brag, but he was what could be called, unironically, a good size. He certainly had no complaints. However, now at his current size he would make a porn star feel inadequate. But there was more than just the increase in both length and girth. Its shape seemed to be shifting, becoming less human and more beastial. The head was growing wider and flatter and something was happening at the base as well. His pale skin was darkening around the base and his scrotum.

His attention was pulled away from his cock by a sudden cramp in his feet. He let out a grunt of discomfort then a shocked gasp as he saw what was happening. His toes were fusing together and his nails were thickening into a solid dark mass. The rest of his foot was stretching and shifting to accommodate the new hoof. His thighs were also bulking up, becoming wider and larger.

Tom found it uncomfortable to sit and was forced onto his newly formed hooves. He took a slow step, and almost lost his balance. Just as he steadied himself on his hooves, Tom felt a strange puckering sensation from his anus. He could feel it growing thick and puffy between his cheeks. He tried to twist his body to see for himself, but all he could see was his now much larger butt.

Patches of fur of various shades of gray were starting to cover his lower body. Including its two newest additions. By now they were recognizable as little horse legs, and were quickly catching up to his original legs in size. Tom found he now had a certain amount of control over the new legs, though their odd placement didn’t allow him to do much. Still, he was able to flex each hoofed appendage as easily as he could move his arms.

Tom felt something pop in his back and he jumped in response. It didn’t hurt, but it surprised the hell out of him, even in the midst of the current chaos. It took another two pops before Tom realized what was happening. His back was getting longer, and twisting into a new shape. Unable to maintain his balance, Tom collapsed onto the floor with a heavy thud.

God, I hope no one was in the apartment below to hear that crash…

Tom tried to get back up, but had little success. He managed to get up onto his side, leaning against the edge of his weight bench. Tom’s back continued to lengthen and he watched with fascination as a new lower body began to take shape. His hips shifted in position, no longer needing to carry him upright. Tom’s new legs started to shift down into position to become front legs. He could feel them almost click into place where his hips used to be, though he supposed they were actually shoulders now. Tom’s rear stretched out further away from his upper body as the new vertebrae popped into place one by one.

Just as he thought his back was done growing, He felt a pressure at the base of his spine. Looking back he could see a nub starting to grow right above his but. It didn’t take him long to guess it was a tail. Its bare flesh was soon covered in long blond hair, a perfect match for what already grew on his head. Taking in his current state, Tom could only come to one conclusion.

“I’m, I’m a centaur. I’m a goddamn centaur!” he shouted out loud.

Hearing it echo in his ears somehow made it more real to Tom. This wasn't a dream or some kind of hallucination. He had the body of a horse with the arms, torso, and head of a human where the horse's neck would be. What else could he possibly be?

Tom’s eyes then caught sight of what had happened to his cock during all of this. The only bit that remained unchanged was the Prince Albert, though the hefty ring now looked like just a small stud on the large equine shaft. His shaft was mostly black now, mottled with a little of its original skin color. A large thick medial ring had formed about a third of the way from the base. Large heavy black balls hung low by a velvety sheath. Tom was surprised just how flexible he now was at what used to be his waist. He was able to reach his new and improved cock, or at least the pierced tip of it. He wasn’t going to lie, it felt good in his hands. His tail swished across the floor slowly as he inspected the flared glans with his fingers, more out of discovery than any sensual reason.

I’m going to need a bigger prince albert. He mused.

Tom felt more of his coat growing in. A light coat of gray fur covered his horse-belly now. Running his hand over it it felt smooth and soft to the touch. Tom noticed now that his hooves weren’t of a uniform color. The left front and right hind hooves were a lighter creamy color, while the other two were dark black. A feathering of fur grew down his lower legs down to his hooves, dark black over his light colored hooves and a very light gray over the dark ones.

Tom felt his body slowly calming down. The tingling and popping sensations had tapered off into nothing, and he didn't feel any bare skin showing below his waist. His cock had relaxed and slipped back up into his sheath, though he could still see the glint of metal from the piercing. He laid on the floor of his apartment for several minutes as he caught his breath and became used to his new form.

I can’t just stay like this all day, I have to stand up. Somehow…

Tom rolled over onto his hose belly and shifted all four of his legs under him. His rear legs seemed to cooperate more than his front pair did at first. He started with his hind legs, slowly pushing his tail up into the air. His front legs slipped on the floor a few times before they seemed to gain purchase and Tom managed to stand up fully. Luckily for him, his apartment was an old building, built with higher ceilings when that was the norm. As it was, the top of his mohawk managed to just clear the ceiling light above him. He knew his apartment was far from large, but it was feeling a lot smaller now.

Now that he was standing up, Tom was able to get a better look at the rest of his coat. Running along the ridge of his lower back the coat was dark gray, almost black. Dapples of lighter gray ran down along his flanks and hindquarters, giving him an almost spotted appearance. As the coat faded to the light gray across his barrel and down all four legs to where the feathering began.

Very carefully Tom began to move, getting used to not only four legs to coordinate, but a much longer body. Unlike walking around on two legs which had been automatic since he had been a child, this required concentration and active thought. He accidentally knocked over a lamp with his tail as he tried to turn around.

“Damn it!” He swore under his breath as he tried to keep his large body from wrecking all of his worldly possessions.

He caught his own reflection in a mirror and paused. He stared at his ears for a moment before touching them gently. Somehow he hadn’t noticed them changing while everything else was. They were much longer now, and tapered into points. Nothing else above the waist seemed changed, the same bright green eyes stared back at him along with his familiar mohawk.

I didn’t realize just how appropriate my haircut would end up being when I chose it. Tom couldn’t help smirking at his reflection. Well, the package didn’t lie, it sure brought out my inner stallion. But for how long? Tom picked up his phone where he had left it on a shelf and checked the time. It’s not even noon yet, I could be back to normal before bedtime for all I know. In that case…

Tom turned on the camera and started to take a few pictures. He wanted some proof this wasn’t just a dream. It was difficult to find an angle that fit his entire body in one shot, but Tom did his best. He smiled as he had fun trying to pose his body.

If I was outside I bet I could get a good one of me rearing up… Tom’s smile faded into a thoughtful expression. Outside, could I even get down the stairs like this? Tom looked around the small apartment. I could use a little space, it’s feeling cramped in her now. What if someone sees me? Do I care? I look amazing! Besides, I always end my workout with a little run. I wonder just how fast I can go now?

Tom made his way carefully to the front door. He was pretty sure the door was wide enough for his flanks, but he would have to duck down. He tossed his phone and keys into the belt pouch he would normally take on his runs. Tom guessed that if he was stuck like this he would be getting a lot more use out of it if pants were no longer an option.

Tom opened the door and stepped out as quietly as his hooves and mass would let him. Moving was becoming more natural with every step. He reached the edge of the stairs and looked down, more than a little nervous. Tom took several deep breaths then carefully started his way down. He stopped twice on the first flight, almost losing his balance, but he managed to slowly get the hang of it. The next two flights got easier, but Tom was still glad to be done with stairs for now.

I knew I should have gone with the other apartment, they had an elevator… He thought as he shook out his legs a little one by one

Tom opened the door and stepped outside. The spring air was still slightly cool, but the sun felt warm on his chest and coat. Immediately Tom felt eyes on him as people stopped and stared. He didn’t feel embarrassed, rather he took pride in showing off his new body. He started off down the street, walking at first and letting his body move freely. Feeling confident he started to trot down the street, loving the sound his hooves made on the pavement. Tom was smiling wide when his eyes caught something that made him canter to a stop.

It was a fellow centaur. They stared at each other for a moment, more surprised than the onlookers were at the pair of previously mythical creatures standing in the street. Tom could see his horse-half was quite different, a warm reddish bay color coat with light white feathering around his hooves. Like Tom, his tail matched his hair color, in this case short cropped light brown hair. The other stallion slowly approached Tom, looking a little nervous and unsure.

“Hey.” He said, putting his hand back behind his head.

“Ah, Hi.” Tom replied, feeling equally awkward.

His blue eyes finally met Tom’s “Power Draft shake?” He asked softly.

Tom smiled “Heh, you too?”

He nodded. “Were you heading to the park?”

“Yeah, I wanted to get used to this body,” Tom pointed back to his flank, “without destroying my living room.”

“Same here. Ahh…”

“Tom” he said his name with a slight nod.

“Tom, I’m Jack by the way. I was wondering if maybe you wanted to test out your new legs with a little race to the park.”

Tom thought about it for a moment then shrugged his shoulders. “People are already staring at us, why not give them a show.”

Both stallions smiled before taking off down the street at a full gallop.
