Trying not to cough up the rather bitter drink, Ryder stood there for a moment before having to race to the water fountain, needing to get the taste out of his mouth. He had been looking online for a higher-tier sports drink to help with hydration, and while the reviews were stellar, in his defense, they didn’t say anything about how horrid the taste was! Oh well. So long as it worked, he figured. It wasn’t something that could be bought in stores, and as best he knew, no one locally had tried it. Ryder had wanted something to give him an edge in his body-building endeavors, and he hoped this would be it!
Taking a few minutes to allow his stomach to settle, Ryder could only hope he hadn’t poisoned himself or the like. At least there was a somewhat pleasant aftertaste, something akin to hops, though he couldn’t immediately place it. At least he didn’t feel the need to vomit, and soon, he realized he wasn’t thirsty anymore. With that, he figured he could work out without working up a sweat too fast and slowing down his reps! Hyperaware of his body, however, Ryder couldn’t help but feel a little overheated, not feverish or the like, but still a little warm. He was oddly itchy, too, especially around his belly, something that made him wonder if he had used a poor fabric softener with his gym clothes. It was irritating, though not enough to stop him as he made his way out to the main room.
Having been attending this gym for months now, Ryder said hi to several of his acquaintances as he got ready to do his warm-up stretches. They nodded as well, Ryan thankful for the camaraderie he felt with some of the regulars. It was nice coming to a place where his fellow gym members worked to build each other up, often helping with spotting and encouraging their reps. Ryder moved toward a small group of guys, doing their stretches before running some laps. It always helped pump him up a little, and today was no different. Still, he was quick to notice he wasn’t sweating yet, unlike everyone else. Hell, if the drink really was working, then it was well worth the disgusting flavor!
Still, Ryder couldn’t help but notice a certain stiffness in his muscles as he stretched, not expecting to be as sore as he was. It was as though the steady heat had worked its way into his muscles, building them up and making it harder to flex them as he was used to. It was hardly the first time he’d felt that way during the start of a workout, and in the end, Ryder figured it was best to get started on his run. If he had to take an extra rest day later in the week, so be it.
Yet, something was off that caused him to wait. Without thinking about it, Ryder’s hands moved to scratch his stomach, even instinctively moving under his shirt. The texture under his touch was a little strange, as though he had become rather more hairy than he was used to. It had to be a bad reaction to his detergent, though he hadn’t changed it in the past few months. Hell, he would certainly have already developed a bad reaction with how itchy it was becoming! Reaching around, Ryder was a little disgruntled to discover it was not only his belly that was coated, but extra hair seemed to have moved up his chest as well, the coarse sensation feeling little like his human bush. Unsure whether it was a boost in testosterone from his recent workouts, Ryder found himself oddly delighted to think it might be having an effect on his body hair!
It seemed the itching was not relegated to simply his chest as Ryder reached up, finding the stubble of a beard that was not present before. The sensation was a little different from what he was accustomed to, and Ryder had to wonder how much he had really paid attention to himself when getting ready. He wanted to find a mirror, though with some of his friends already starting their run, he figured there was no point in waiting. Even the slight prickling in his ears or the persisting itching all over was not enough to deter his excitement as he took off, a surge of energy pounding through him that he hadn’t known before.
Despite being still sore, it was hardly a deterrent as his legs pumped and he found a decent rhythm. He had been getting faster with his runs, but never before did he feel so strong! Starting out at a steady pace, Ryder soon found he was able to move faster, not getting winded as he ran around the circular track. His muscles pumped, lungs taking in big gulps of air as Ryder ran all out. The only thing to slow him down slightly was his hair getting in his face, which shouldn’t have been the case. His clothing felt unnaturally tight as well, his shirt riding up and thighs pressing against his shorts. Fuck, if this kept up, he was going to need an entirely new wardrobe!
After he finished, Ryder couldn’t resist the urge to play over his belly and arms, excited to discover if they really had gotten larger. Being generally in tune with his body, Ryder was a little surprised to notice a difference in tone, the muscle thicker under his touch. It was somewhat alarming to discover his belly was larger than he was used to, Ryder wondering if he simply didn’t realize how many snacks he had been enjoying as of late. But feeling up the skin, Ryder couldn’t muster any concern for its state of being. It clearly felt like muscle, and the rounded contours appeared more natural, after all. Hell, he’d wanted to get buff, and there was nothing wrong with the results so far!
Not expecting to feel a shiver of arousal as he felt himself up, Ryder felt himself growing somewhat embarrassed as his thoughts focused elsewhere. It took him a few minutes of sitting down for his penis to retreat, though the size of the bulge was rather impressive. It hadn’t ever looked so large before, but no matter how he reflected on it, Ryder could not find fault with its current state. In fact, he couldn’t help but grin as he sat there, privy to something that other men could only dream of owning. While workouts and better eating shouldn’t have influenced his manhood in such a way, Ryder could only think of the positives. And maybe how he might tend to things later as a result of his hard work!
Sitting down also left him aware of how thick his thighs felt in his shorts, so much so that he worried they might pop off. How the hell had he gotten them on a half hour ago when they were so damn tight now? It was hardly the only part of his gym clothes that seemed ill-fitting, even his shoes, which was odd. If he didn’t know better, the tips of his toes were swollen within them, making him wonder if he had injured them. Part of him wanted to take them off and check, though his surprisingly larger belly made bending down difficult. In the end, he found it hard to hold on to his concerns, the energy pulsing through his muscles leaving him unable to concentrate.
The only persistent annoyance was the itching over his belly and chin as Ryder got up and made his way to the benches, careful not to pull his clothes too tightly over him. Yet, the excitement to show off was quick to repress his concerns, and he lay down, forgetting to set the weights as he started to pump. Much to his surprise, the previous weight was set at more than he was used to, leaving Ryder to grunt a little from the effort. Yet, the part of him who was determined to show off forced himself, and soon the weight seemed almost easy. The power in his arms seemed to steadily rise, and as Ryder did his reps, he soon found it effortless.
Ignoring the tightness in his shirt, Ryder set the weights back on the bar before moving to add more weights on the sides. Normally, he would think only to add five or ten pounds at once, though with some bizarre curiosity, Ryder added a solid twenty-five to either side before getting down once more. The sensation of something above his ass being crushed made him yelp, and Ryder had to angle himself in order to alleviate the irritation. The position made it harder to lift, but soon Ryder got into it, finding the effort difficult for the first few reps. Like before, his muscles quickly acclimated, and soon Ryder was ready to put the bar down, eager to discover the upper limit of his new strength. The fact that his arms were mammoth compared to just an hour ago didn’t seem to sink in. Ryder was simply elated to be able to show off his prowess!
Ryder’s exploits did not go unnoticed for long, and soon he had a small group of onlookers cheering him on. Normally preferring not to be the center of attention, Ryder was now elated by it, doing his best to keep going, lifting as his muscles trembled. As annoying as it was to deal with his itchy skin, it was hardly a deterrent as Ryder focused on his reps. A few of the guys offered to spot for him, asking if he needed a break or water. Too engrossed in his lifting, Ryder ignored their warnings, occasionally asking for more weight. While his muscles strained, they seemed to knit back together so fast that he was hardly hindered. No matter how unnatural it was, Ryder couldn’t help but delight in all that the drink seemed to do for his body. It was supposed to keep him hydrated, right? Not give him the stamina of a workhorse!
Too late, Ryder was just becoming aware that the prowess of his body had a rather unwanted effect on his arousal. The tent in his pants was somewhat more impressive, and Ryder could feel its tip leaking, pleasantly pushing against the fabric. It was all he could do not to rut against it, forgetting he was in a public place and being watched by dozens of eyes, no less! Yet, it seemed like everyone’s attention was on his arms, and despite himself, Ryder could not stop grinding his cock against his underwear. Lost in lust, he almost felt as though he was going to cum through sheer arousal from his physical prowess alone. And there was no reason for him to hold back, as much as his driven mind could reason.
The force of his orgasm washed over him in waves, Ryder pumping faster as he rode the release. It was enough to create a noticeable stain in his shorts, though hardly enough to stem the pressure of his penis pressing against it. The scent caused a noticeable shift in the people around him, pulling back as the pungent stench made them concerned. It mattered little to Ryder, who was unable to focus on more than the physical pleasure. And it was growing with each passing moment, even as his sperm soaked the insides of his underwear. Even his release was not enough to subdue his erection, and the pressure of which caused a resounding rip to echo in his altered ears. For a moment, the cool air on his cock caused him to shiver and relax, finally setting the bar back on the stand. Too late, however, Ryder came to realize that his penis had torn through his shorts and his maleness was on display for anyone to see!
Rather than simple cries of disgust, however, some of the onlookers were rather impressed, whistling under their breath. It was almost enough to suppress Ryder’s shame, though he knew he couldn’t stay there exposed. Getting up, the force of his thicker thighs was nearly enough to burst through the sides of his shorts. And his shirt had pulled toward his chest now, annoyingly tight around his pecs and over his shoulders. It was a wonder he could move without tearing it, and a sense of shame finally washed over him, embarrassed about what he had done. Even his retreating penis was not hidden with the hole in his shorts, and he finally saw it fit to cover it with his hand. There was no living it down now, even if by most metrics his maleness was enviable. Still, he was thankful when one of the guys loaned him a larger pair of shorts, and he made his way into the bathroom, hoping to get cleaned up and leave.
Yet, the sight of his visage in the mirror caused him to pause, forgetting the pride he’d experienced from his sizable penis and enviable muscles. First off, his ears were massive, noticeably sticking out from the sides of his head. Pointed and conical, Ryder reached up and touched them, jumping out of his skin as they twitched against his inclinations. Exploring them more tentatively, Ryder was shocked to discover their brownish shade was the result of finely layered hairs, almost velvet soft as he rubbed at them. Even their movements no longer seemed to trouble him, and Ryder was curious about their shape and abilities. There was no denying that sounds from outside the washroom were louder, making his ears twitch in an effort to take them in.
Still, it was not a distraction from the other alterations to his face, things that were becoming more evident the longer he stared. Firstly, there was obviously something off with his eyes. Having always been brown, it was the irises that alarmed him, more rectangular than oval as he’d been used to. Having been flipped over on their sides, it gave him a haunting visage, though intelligence and fear were present in the otherwise inhuman stare. They might have been a little larger as well, though with the shifted contours of his face, Ryder couldn’t be entirely sure. And his nose took up an odd amount of his reflection, massive and red, with the base nearly connecting to his thicker lips. It should have scared him to discover such inhuman alterations to his visage. And yet…
Rubbing his beard, Ryder was further confused by the texture, finding it softer than his human hair might be. It seemed to run up his sideburns as well, bringing to his attention how thick his hair was becoming. It was longer, coarse, and rough, reminding Ryder of how much he needed a haircut in addition to a shave! While Ryder hadn’t noticed it before, it seemed his nose was not spared by the fine hairs, either. While the hairs were short, the longer he watched, the more the skin seemed to whiten, covered with a bit of fuzz he couldn’t quite place. The sensation prompted him to pull back his lips a little, and Ryder was greeted with the sight of teeth a little larger and more blocky than he was accustomed to. Their slightly off color, as well as the state of his lips, should have caused him some concern. Yet, he couldn’t quite place why he looked different, his body sore and making it hard to focus for too long.
Yet, despite the decidedly animalistic features he seemed to sport, Ryder couldn’t fully deny his excitement over the power he had gained within the last hour or so. His arms were mountains of muscle, easily able to lift more than the bars could challenge him with. His shirt was super tight, of course, exposing his paunch of a belly that was more muscle than fat. Rubbing the skin, it, too, seemed far hairier than he was used to, though the texture was surprisingly pleasant as he teased his fingers over it. Oddly, his seeking fingers seemed a little stiff and unruly, the middle digits swollen as though they had been crushed. Still, it couldn’t deter his fascination with his massive stomach, firm arms, and larger stature. He was getting ripped without even trying!
Needing to get the borrowed shorts on to make it back out to the floor, Ryder was a little surprised to discover that they were several sizes larger than his old ones. Even then, getting them over his thighs was still troublesome. It wasn’t helped by the fact that his feet felt oddly numb, or that taking his shoes off was meddlesome. Like his fingers, the middle toes seemed swollen as though they had been injured against the inside of the shoe. Balance precarious, Ryder eventually managed it, thankful his cock had retreated back into his foreskin. If he got hard again, he was sure to burst out of even these shorts!
As interested as he was in his cock, it was the other lump that soon had his attention, and seeking fingers played over its contours. Figuring he must have bruised his tailbone, Ryder found himself unable to think of what else might have overcome him. The protrusion was warm, thick, and itched as though it was growing hairs like those atop his head. Worse was getting his pants on over it, and Ryder had to lament the fact that it irritated him while it was confined. Had he ever possessed something like this before? What was going on?
Yet, that persistent haze that kept plaguing his mind made it hard for him to focus on his problems for too long. His thoughts kept drifting toward his workout and his power and vitality that came with today’s efforts. The words of praise and looks of admiration were worth any of the bizarre changes. And surely with how large his muscles had become, he would be able to show off even more!
This time, Ryder opted to sit down at one of the stations to pull some weights. The bump in the back of his pants got in the way, though with some effort, Ryder was able to find a comfortable position. Setting the weights several dozen pounds higher than the last person, Ryder started to flex, working up a steady rhythm to challenge his new build. Yet, it was painfully obvious that his body was far stronger than who the weights were for. Grunting a little, Ryder moved to add some additional weight, hearing some sounds of encouragement from people around.
Still, it was getting harder to sit there, clothes further tightening over his body. Annoyingly, his hair kept getting in his face, and Ryder began to notice it was lighter than his usual dirty blond. It was difficult to bring himself to care, save for the irritation as it tickled down his face and nose. All he could do was twitch his face, snorting a little to blow it out of the way. With his arms occupied pumping weights, he had little concern with how tight his shirt was becoming, even when the tension against his nipples seemed to abate. Even his larger shorts were strained by the size of his thick thighs, though Ryder couldn’t help but think the reality was exciting!
A sharp tear down his shoulders caused him to hunch them a little, feeling the split move all the way to the edges. Ryder was eager to flex a little, pushing the shirt fragments to the front. Sleeves were pulled tight with the force of his expanding biceps, and with some effort, he was able to manage to work it off. Sparing a glance down, Ryder was somewhat aware he was now far hairier than he should have been, even within the past ten or twenty minutes. Yet, it was hard to find fault in what was happening, especially with the claps of encouragement from everyone watching. Surely, they had never seen someone lift so much, and Ryder felt proud to give them a show!
Standing up too fast, Ryder almost felt himself pitch forward, feeling far more massive than he figured was possible. He was sore, too, and not just his arms from the lifting. The aches seemed to be settling in his jaw, Ryder finding his chin was somewhat distended as he rubbed the skin a little. Hell, it was shocking to feel how large it was, Ryder almost able to see it in front of him if he rolled his eyes. Efforts to talk made him aware of how hoarse his voice had become, though coughing seemed to alleviate it somewhat. It was confusing, though the expressions on the faces of his onlookers didn’t help him place what was wrong.
In the end, Ryder figured it was best to check out his face in a mirror, moving toward the bathroom once more. Yet, he was soon made aware of how awkward his posture was, especially with how his heels seemed to have stretched and with his feet almost painfully tight in his shoes. Without thinking, Ryder moved to pull them off, though his belly was far too large to manage him reaching them. All he could do was snort his frustrations, walking carefully and trying to ignore the persistent numbness. His balance was off, and in the end, it didn’t seem to be worth the trouble to observe what was wrong. He still felt strong, powerful in a way that defied his expectations. As eager to show off as he was, Ryder figured any potential problems could wait!
Any embarrassment about being shirtless was mellowed by all the stares he gathered from everyone around. Surely, it wasn’t up to the gym’s code of conduct, yet people seemed more fixated on his physique than his adherence to social norms. He was massive, muscled, with a thick belly and a furry treasure trail showing off his new prowess. Hell, if anyone wanted to come up and touch it, he was confident he would allow it!
Not sure how best to test himself, Ryder ended up sitting on a bench to do some curls. Careful of the growth above his ass, though ignorant of its meaning, Ryder moved to curl what he could find, the heaviest weights were no trouble for him. Part of him wanted to seek out even higher weights, though his arms were starting to get a little stiff. They weren’t sore, not exactly, though it was becoming harder to move them in the way he was used to. It was like the muscles of his upper arms and shoulders had torn apart and knitted together, drawn closer to his muscled chest. Yet, with the trade-off of muscle mass, it was hard for him to hold onto any worries for long.
Of greater concern was how much harder it was to hold onto the weights, as though his fingers weren’t able to wrap around the bars. His middle fingers had begun to stiffen against his will, as though the joints to curl them were popping apart. Stranger still, the rest of his fingers seemed numb, barely able to respond to his mental commands. Struggling as he was, Ryder soon felt the weight slipping from his grasp and hitting the floor hard. All he could do was raise his hand in curiosity, surprised to discover the middle digit was so much larger and thicker than what he perceived was possible. It seemed to be pushing against the rest, until little space was left for their presence. And it was happening at such a rate that he would lose all ability to move them soon!
Yet, the more his digits shrank, the more the muscles in his arms continued to bulk up. It was a wonder he still wasn’t sweaty, though a rather pleasant odor wafted into his nose, unfamiliar though alluring all the same. Against his better inclinations, Ryder felt his cock surging in his pants, straining to burst through. Surely, he couldn’t touch himself without functional hands, and such should have been frightening. Yet, all he could think about was how aroused he was, how much his cock was pulsating under his pants. It hurt to have it confined, but beyond the inconvenience, the size of his meat caused the stain to soak through his borrowed pants. If his cock was to grow any more, it might burst right through once again! A penis worthy of the Adonis he was becoming…
As though in a trance, Ryder got up to sit on the bench once more, trying to raise the bar above him rather than lying back. Careful of his altered fingers, he managed to find a position that allowed him to lift without the risk of dropping it. He was so much stronger now, and as easy as it was to hold such a thing, part of him wanted to stand up and walk with it. Almost as though it would be better if he could…pull it? Confused, Ryder shook his head, surprised by how much hair was getting in his face. He didn’t need to see, however, a massive nose awash in the scents of his body and masculinity. And he could scent those around him, the crowd that had gathered to view his exploits. Yet, rather than admiration, their odors now spoke of something else, a concern that Ryder couldn’t quite place. It was as though they were scared of what they were seeing, though Ryder couldn’t imagine why. It all felt so normal, so natural, and the more Ryder used his new muscles, the better things settled in his mind!
No matter how many people had gathered around him, Ryder couldn’t bring himself to stop. It was as though he needed to push, to prove his power, and nothing else mattered in the moment. Such was more arousing than anything he had experienced before, causing his cock to further strain his borrowed pants. The tension within his thick testicles demanded attention, though the urge to push himself was at the forefront. And even the parting in his pant seams couldn’t deter his efforts. It felt like he could cum from that stimulation alone, something Ryder was eager to welcome as his pleasure grew past the breaking point.
The force of his surging dick finally parted the fabric, erupting with a torrent of jism the moment it did so. The force of it was more than he could bear, Ryder feeling his body stiffening from exertion. A pungent odor flooded his nose, speaking of his virility in a way that he could not possibly have known about before now. Yet, as splash after splash of cum soaked his chest and groin, all Ryder could do was pull back his lips, crying out his lust. The deep equine inflections did little to deter him, nor did the sheer amount of horse cum he was ejaculating. Despite being naked and exposed, Ryder couldn’t deny the pleasure that came with release. That, and his body was huge, still begging to be used to the fullest!
Coming down from the most intense orgasm of his life, Ryder was hardly concerned with the cries of panic or snapshots from phones as they recorded his activities. Instead, he put the bar back on the stand, regarding his new cock with some curiosity. What he was packing had clearly lost all its humanity by this point. The head was thick and flattened, a crown running around it as his wide urethra still leaked cum. His glans had shifted to the center of the shaft, the skin of which had altered to a mottled pink with black splotches. As his erection waned, Ryder was prompted to rub at his ponderous foreskin, so thick and silky it was able to encompass his entire length. Soon, all he could see was the still-leaking head, though the tension in his testicles had hardly ebbed yet. Much to his delight, Ryder was sure he could go again, his mammoth strength spurring him on.
With some effort, Ryder stood, annoyed at the cum drying over his copious body hair. Thankfully, he found a mirror nearby, and he was able to take in the scope of his new body. It was his head that was truly startling, equine features becoming more pronounced as he watched. Lips were rubbery and black, and with some delight, Ryder found he could pull them back quite far. With splotchy gums and thick, yellowish slabs for incisors, Ryder had to admit he possessed a rather goofy appearance overall. Flaring his massive nostrils, Ryder couldn’t help but chuff, breathing in heavily of his essence.
The changes were hardly limited to his mouth and nose, even as pressure in his jaw started pushing it forward. There was something off about his eyes, and Ryder was forced to blink a little as they watered. Opening them again, Ryder was somewhat disappointed to find that some of the colors in the room appeared washed out. Yet, of more alarm was the shape of his irises, long and rectangular rather than oval. That was if he could see them through the thick hair getting in his face, causing him to snort. It was annoying, especially as the itching caused it to run further down his back. Yet, nothing about his altered visage could bring him real alarm. Reaching up with a curious hand, Ryder delighted in the soft texture of fur that had taken form over his nose. He looked more like a stallion, but with all the muscle and arousal that came with it, Ryder could only find it hot as hell!
As thick as he had already become, Ryder felt a sudden surge of pressure, as though his body had much more to give. The tension in his ass was enough for him to bellow out his irritation, fabric pushed to the breaking point and beyond. The cascading rips allowed his backside to breathe, at least, donut-shaped anus kissing the air and causing him to shiver. He could feel it pressing at the ill-fated fragments of his underwear before they burst apart, uncomfortable but sensual all the same. His pucker was puffy, left exposed by spreading hips. Strangest of all was the feeling of coarse hair tickling his bare legs, causing him to whinny in panic. Though as Ryder explored the movements of his new growth, he was left to whicker his delight. Its white hairs hung proudly behind him, nearly touching the floor. Raising what had to be a tail left him wanting to prance and show off, something only a beast like him could possess!
Ryder was barely given a moment to enjoy the changes, however, before a further surge of growth caused him to pitch over. It was happening too fast at this point, and unlikely to stop until it was finished with him. Thighs were now far too bulky, pressed up against his massive, muscled belly. A surge of pressure in his chest from expanding ribs caused him to be short of breath, and Ryder wondered if he was in danger. Guts were gurgling, his heart was racing, and muscles pulled and tore under the skin. He was rapidly becoming massive, yet even with how restricted his torso felt, Ryder couldn’t help but delight in his strength. If he couldn’t lift weights with the new configuration in his body, surely he could at least pull!
The pressure in his feet soon grew far too intense, and Ryder put out a warped hand to steady himself, not wanting to topple over. He had been steadily aware of a persistent numbness, though he was still surprised when his efforts failed to move his toes. It was as though they were entirely absent, like tiny stubs sticking out of the sides of his feet. His middle toes were massive in comparison, numb, even though they were obviously the source of the pressure. As the sides of his shoes popped apart and his feet were allowed to breathe, Ryder took a step forward, shocked by the sound against the floor. A heavy clop reminded him of horse hooves, and Ryder did his best to kick away the trappings. He wanted nothing more than to expose his hooves, though not out of fear for what he had lost. Rather, Ryder was all too excited to own appendages that could hold up his massive, muscled body!
Soon, his other hoof burst from its confines, pulling the fabric of his socks to the breaking point as well. While Ryder could perceive his numb toe tips within, what had been his nails had thickened beyond the scope of what he figured his foot could support. It was hard to balance on them, especially as his feet shrank and his heels doubled in width and girth. Pitching forward, Ryder was thankful for the massive arms he had been granted, able to hold him up against one of the benches. Thinning calves and fat thighs gave him a semblance of equine hindquarters, though in the moment of ecstasy, Ryder only welcomed further changes!
An intense itching drew him from his reverence as hundreds of white hairs burst from just above the hoof. While dark brown hairs had been steadily encroaching over his skin, these white hairs were far longer, nearly reaching the floor. They flowed rather nicely, making it hard to see his hooves, though not obscuring them entirely. As he stamped the ground, enjoying his new muscles and flowing fetlocks, a new thought crossed his mind. He had not put his massive legs and ass to the test yet, and he was quickly becoming aware that the gym equipment would not do. A beast with the muscle mass he possessed should be able to pull a massive cart, a wagon, or even a car! And if he continued to grow as he was…Ryder could only whicker his excitement, powerfully aroused by the prospect.
The force of his erection drew enough blood to cause Ryder to feel dizzy, wavering there as he held himself up. Yet, as his thighs and ass continued to swell with bulk, the scope of his erection was reduced enough that he could take stock of it. The fact that it looked like it should belong to a beast mattered little with the level of sensitivity it possessed. He simply had to rub it, shivering from the contact. Even with his fingers somewhat stunted, he was able to feel a modicum of pleasure, as though a prelude for what such a rod could grant him. It was something meant for a true Adonis, and all Ryder could do was shake his head, mane flicking as he nickered his lust.
Yet, the changes were hardly to stop there, and Ryder felt his frustrations rising. His barreling belly made it harder to grip his cock, even though it was pleasant to feel it slap against it as he struggled. While its length was more than enough for his fingers to tease the head, his muscled belly caused it to arch downward away from his arms. Worse was the steady ache in his back as it lengthened, causing the weight in his chest to shift. It was a wonder he could stay standing, only able to use one arm to balance as he worked to stroke himself off. In truth, a penis this size should require two hands, even with as large as his middle digits had become. Yet, the pleasure was so sublime that even his struggle was not enough to deter his goal. Piss head already leaking, Ryder delighted in the sensations, viewing his body as a vessel for his enjoyment and fixated only on the release to come.
Yet, his pleasure was soon to be stifled as the stiffness within the digit grew to a head. He was forced to drop his penis, fingers trembling as they started to rapidly deflate into his hand, leaving only the center ones in their place. While a part of him shouldn’t have been surprised by such a reality, it was still enough for him to whicker his panic. He could barely perceive the tips being subsumed by a spreading nail, soon so thick it was on its way to matching his hind hooves. Yet, while he was happy to clop his former feet, the loss of his hands was far more drastic. Without them, how would he stroke his magnificent cock?
All Ryder could do was feel his middle fingers enlarging, filling up the space to match his extending wrists. Soon, they had become massive, allowing more space for hooves the size of a beast such as he needed. The weight of them was already impressive, even though their presence was somewhat distressing. Thicker layers worked out from his fingertips, hollowing in the center, with spongy material to absorb his impressive weight. Yet, his arms had grown so powerful by this point that holding them up was a breeze. While he could feel the rest of the fingers sinking into his wrists and the bones of his palms compressing, it was becoming harder for him to be concerned with that reality. Like his back hooves, they were rapidly reaching the circumference of a small plate. And with the now-familiar itching of fetlocks setting in, their magnificence caused him to whinny, this time out of elation.
Yet, a panicked whicker escaped his rubbery lips as another surge of growth racked his body. Already top-heavy, the force of it was too much for him to handle, and he tipped over, arms extended to catch himself. With the way they were positioned, it was easy even for his weight to be supported as his front hooves hit the floor with a large clop. While he felt no pain from the impact, the effect was enough to send surges of growth through his body. As large as he was, a massive belly still had room to swell with meat and muscle. More cracks resonated through his chest and torso, making his stance straighten as his shoulders pushed forward. Surely, he had to be several hundred pounds larger than humanly possible. Yet, with the breed of stallion he was on his way to becoming, there could be many more hundreds to go.
Now steady on all fours, Ryder was delighted with the persistent cracks and pops that were a sign of further growth. It didn’t escape his notice that he was a magnificent display of horse flesh, quelling any fears over his changing form. Surely, he was on his way to becoming the hulking behemoth of his dreams, and it was impossible for his mind to find fault with his lost humanity. All that concerned him at present was the lack of ability to jerk off his horse cock. Yet, as he thrust his massive hips, the sensation of his member slapping against his belly allayed those fears. Swaying testicles rubbed against his legs as his horse’s penis worked against his belly, creating a wonderful friction. Precum flying everywhere, Ryder was left to whicker his delight, sure it wouldn’t take much longer to spray his maleness all over the floor.
While his body was massive in comparison to his former stature, Ryder’s head was still comically small in relation to what he had become. His nose was thick and flared, his ears could rotate around, and his lips felt numb and rubbery. However, he was well aware that the alterations to his visage still had a way to go. Thick brown fur had erupted from his former beard as his face cracked forward, jaw aching in its struggle to keep up. It hurt, though Ryder was more distracted by his expanding nose, so much so that it took up a significant space of his field of vision. It felt well worth it, however, as his nostrils were given more space to truly drink in the room. A myriad of things were made known to him, others’ sweat and perfumes that escaped his human self. Yet, of far more importance was the randy odor of horseflesh wafting off his body. He reeked of maleness and virility, and Ryder could only revel in the smell. Muscles twitched and swelled under the skin as it shone with his health and virility. He was becoming bigger…massive…more of a sexy beast with a cock to match!
With the changes to his skull, Ryder found his thoughts blurring, making it hard to concentrate on the past. He was still human, though his mind was dull and his feelings were defined by the instincts of the animal he had become rather than the human he had lost. The pleasure radiating through him was simply far more potent than anything the human was able to wade through. Everything simply felt too good, too right in his new body, as though he had been born a horse. And if not, a Clydesdale stallion was simply too appealing a form to possess, and he could hardly regret what he had become. Especially as the pleasures in his massive penis came to a head!
As much as he had grown over the last few moments, Ryder still fell short of the stallion he was destined to become. While the exertion left him tired and sore, it was hardly a deterrent for his desire to reach that pinnacle. Ryder struggled to adjust his massive hooves several times to allow his torso to thicken, his chest to barrel, and his ass to expand. Hundreds of pounds were being packed on in mere moments, and even Ryder’s fuzzy mind was aware he must have been well over 2000 pounds now. Such was natural for a beast of his stature, however. He was becoming a Clydesdale stallion in his prime and eager to show off his prowess, both physical and sexual!
His focus now was only on the power in his body and the ache in his cock as he continued to rock his massive bulk. His firm belly was the perfect foil for his mammoth horse cock, each slap sending sensual shivers through his entire being. The only thing better might be to have a breeding stand or an eager mare to take his meat, though in some ways, Ryder concluded this was sufficient. Masturbating like this was all under his own power, after all, leaving him to whicker and neigh his lust. Calls of confusion and disgust were easily ignored with each slap against his belly. Thick strings of pre-cum flew from his flared cock head, some of it landing on the onlookers. Yet, Ryder was remiss in caring, only concerned with the pleasure his new penis could provide. And doing so in front of a crowd could barely bother him, not a stallion of his stature!
Massive swaying testicles throbbed intently as the final slap sent a shiver down his body. Waves of horse cum shot through his penis, spraying over his belly and the floor below him. His entire body was left to quiver, the rank scent of semen burning into his nostrils. That, mixed with his heady equine odor, left him powerfully relaxed, proud of his power. Every burble of cum seemed to send a surge of growth through his being, providing the additional bulk he had been craving. His only discomfort came from constantly shifting his stance, hooves heavy on the floor and fetlocks tickling the base above his hooves. Thankfully, his power was more than enough to lift his massive dinner plate-sized hooves!
With that, Ryder was left to stand there panting, his cock dangling as thick strings of cum oozed from the tip. It was retreating slowly into his mammoth sheath, pleasant as the fuzzy skin worked to subsume it. Ryder was soon more fixated on his body, however, especially now that the tingling of transformation had finally ceased. As best he could tell, much of his new bulk was muscle as he shook his heavy body, reveling in his power. It was amazing to be standing there, so much larger than the humans still watching him, some likely wishing they had achieved what he had. At the moment, Ryder could not recall ever being happier!
Thoughts were still muddied, even after his orgasmic reverie finished with him. It mattered little, however, Ryder found little else to think about. He was hungry, to be sure, his massive frame able to eat like, well, the horse he had become. And the scent of drying cum on his belly had a nice implication to it, proof of his power and virility. Even the discomfort of being coated in sticky cum was easy to ignore over his post orgasmic contentment. Ryder was sure he had never felt this way before, that this body and life were not truly his. Yet, it was difficult to recall his old body or even any appeal in possessing it. Nothing from his past life could hold a candle to being this massive, muscled beast! Except maybe for the grumbling in his belly…
After what felt like far too long, several men smelling of hay and horses entered the gym, brandishing carrots and other treats that made Ryder’s mouth water. In truth, he was eager to leave now, his massive belly gurgling from hunger. With all the bulk he had gained, it would take hours for him to be satisfied! It seemed these men were of the same accord, and Ryder acted the gentle giant, following them eagerly and giving them the occasional nudges with his massive head in an effort to coax more treats from them. It seemed the men were thankful for his calm demeanor, though their words meant little to his altered mind. Ryder was simply hopeful they would take him somewhere with plenty of food!
Ryder eagerly clopped toward the door, surprised he could fit through the back. Still, the scents of hay edged him on toward a massive trailer parked there for him to board. It seemed they planned to rehome him, though Ryder hardly found fault with that. While he could still remember who he had been, the promise of this equine body seemed more appealing than his previous life. Perhaps it had to do with his dulled intellect or sheer enjoyment of his powerful body, but regardless of what happened, he didn’t think he wanted to be changed back!
A passing comment by one of the men caused his ears to twitch, though the words meant very little to him. “How the hell did a horse get in there, anyway? Poor stud barely fits through the back door,” one remarked, and Ryder could only whicker his amusement. It was amazing how the human mind could trick itself into deceit, thinking there was no way a man could become a horse, and having to delude themselves into a more mundane explanation.
Ryder cared little, however, even if they thought he was a naturally born horse. “You’re a gentle one, aren’t you, boy,” one of them said, patting him on the flanks. Ryder whickered at that, shaking his head and flicking his mane. All he could do was to hope he was taken to a good farm, to be well-treated and cared for. And given the chance to show off, Ryder fixated on how much his several thousand-pound bulk could pull now!
