Man into Male Horse Transformation Story | Nudity | Mild Humiliation

Greg slowly woke up and immediately realised he wasn’t in his bed, despite being naked. Judging by the cold and damp air he wasn’t even in his room. He groggily blinked his eyes only to find out that the room he found himself in didn’t even look humane. It was some kind of cell, but without bars and with venetian mirrors all around from the looks of it. From the ceiling hanged a single monitor and speakers.

Greg was no criminal, why would anyone abduct him? Especially somebody wealthy enough to build specialised confinement rooms like this. Was it possible for the facility to have been built by the government…? No, that would be too much. Greg tried to reason with himself, since the room didn’t seem to have any weak spots to escape through – Just smooth walls. He came over to one and started knocking on it and then hitting it harder – Shockingly enough it had no effect on them, except making a few barely audible thuds.

“You’re temperamental, you’ll do fine as our test subject. Initiate the procedure…” – The supposed captor’s voice seemed to be ominous to Greg’s worries. “Hey! Let me out of here! Why am I locked in here…?!” – Greg yelled at the wall with no better option. His questions were left unanswered, but as his head gave up on questions he started putting the pieces together. He wasn’t locked in a standard cell, there were venetian mirrors everywhere, they just initiated some procedure – He was a test subject to some demented game or experiment? Time for pondering ended as the room got filled with silent sounds of hissing. Greg looked up and realised that some dispensers started pouring thick purple gas into his chamber. Grim thoughts immediately hit him – They just wanted to kill him and in such a horrible way?! Greg ran a circle in the chamber, until he felt the gas reach him – He stopped breathing not to inhale the gas, but he knew he would eventually as the gas had nowhere to go without the captors will.

Greg was frightened at first, but now he felt helpless and furious at his abductors – He didn’t deserve this! “Oh fuck y-agh! Ackh-kh…!” – He insulted his tormentors, but was interrupted by instinctive coughs once the gas got into his respiratory system. The effects of the gas started working on him immediately. Greg had trouble balancing on his feet as he started to get light-headed all of the sudden. He realised he was doomed, he expected to pass out and never again wake up. Instead he felt goosebumps rise all over his skin, followed by heat as if he had intensive fever.

“H-Huh…? What…?” – He mumbled, before more uncomfortable changes started working on his body. His skin started feeling strained, literally. It felt too tight on his body as it started to gain size and bulk, his skin had hard time keeping up with his body growing additional muscles and fat mass. Greg shuddered as he felt his increasingly heavy movements. His back started crunching and broadening altogether for all of his forming muscles to make sense on his final body shape. “Oh G-Ghoood no! I’m ch-changing…! Agh-hck…!” – He groaned in pain as he was forced to arch his back when his spine started to thicken considerably. Each vertebrae started to press against his flesh and force him into a more feral position, he already great trouble balancing on two feet.

His huge mass and altered spine was too much for hunched over Greg – He willingly gave up his stance and dropped onto all fours. He panted hard exhausted of his intensive changes and horrified of them. His face started to hurt at certain points and Greg watched in plain sight and horror as his nose started to swell larger in his vision. It widened considerably, his nostrils flared out into inhuman shapes. The front of his face started disfiguring and pushing out into an animalistic snout of a beast. Subtle changes like his lips swelling larger and heavier, his upper one fusing partially with his growing nose. “Ogrh mry- I- I hrave a snrout…!” – He muttered terrified, but his face was just one of his many shifting body parts. Unbeknown to Greg the scientists who initiated his changes watched them warily and noted everything on their computers. They had Greg’s grotesque changes in clear sight and curiously watched all of them.

Greg crawled towards the mirror wall ahead of him, groaning in the process with every movement as his body was a mix of two species for now which along with changes made it painful to move. His limbs crunched and snapped becoming thicker and longer altogether, but most notably his ankles and arms. Greg reached the wall and saw the outlines of his morphing reflection in it instinctively shaking his head in protest – It wasn’t him in the reflection. His face slowly marched outwards forming a blunt and huge muzzle, every feature on his head was becoming wilder in appearance and most of all inhuman. Even his eyes started aching as they changed – Pupils dilated and expanded his vision horizontally. Greg coughed and had trouble to breath as his entire respiratory system morphed.

His already thickened chest started to barrel out and expand, every organ inside did so as well – Most notably his lungs. When the changes in his huge chest slowed down he was able to breathe again, but not as he used to as a human – By now every breath felt heavier. His shoulder blades snapped and started elongating, becoming bulkier while his arms were pulled higher up on his massive chest to fit his soon to be permanent four-legged stance. “G-Ghaaaah…!” – Greg exclaimed in pain as his spine suddenly jolted and shot outwards, putting a quick, but immense pressure on his tailbone until it shot outwards and started growing out into a tail. Greg stared at his growing reflection utterly devastated, he even saw the blurred contours of his growing tail wriggling and then twitching behind him as it slowly finished growing and finally settled down.

Greg hanged his head low hopelessly and that’s when he noticed his elongated and anatomically reinforced arms. At this point there resembled fore legs more than anything else. Greg was so absorbed in his obscene transformation that he didn’t even try to guess what he was being forcefully changed into. Only now as he stared at his hands, what used to be them did he realise. His middle fingers were huge in comparison to his other digits, which were getting absorbed by them even with wet bone-crunching sounds. “E-Evhren mhry hands… Whrait! Ohr nhro…!” – He gasped as he stared at his thickening middle fingers, by now they were his only digits. On them his fingernails grew huge in comparison to what they used to be, more worryingly the keratin mass started forming distinct shapes of equine hooves. What used to be his hands gained more equine contours and slowly formed his hooves which just finished blackening into adequate colours. “I crant bre a horse, strop thris I breg yrou…!” – He pleaded again and pounded at the glass wall in front of him with his thick hooves. The scientist made new notes describing Greg’s behaviour and responses to the changes. Greg sighed surprisingly loudly, almost sounding like a horse’s snort already.

His body was huge at this point and he was about halfway changed into a full-fledged stallion judging by his own reflection. Even his skin changed by now – It became thicker, darker and resembling a hide more than anything. Greg didn’t want to endure the changes without even trying to stop them. His body continued to shift violently, but Greg leaned against the wall and started getting up – Unwillingly giving the scientist a better view at his changing anatomy. As Greg got up onto his feet solely again and only because he had the wall’s support, he felt his feet start to shift dramatically. His lengthening ankles cracked and forced him to stand on his two enlarging middle toes. All of the other digits of his previous feet were melting down into nothing. He groaned as his middle toes toughened up and became more solid to bear his great weight. His toenails bundled up together, fused and started forming hooves. In a matter of seconds his feet were completely replaced with hard equine hooves.

This didn’t stop Greg from savouring his little achievement of staying solely on his legs again. Unluckily for him his fore hooves started sliding off the wall and he was going back onto all fours inevitably. He realised there was nothing that would stop his metamorphosis at this point and it drove him mad. Greg breathed hard like a stallion that he was becoming and he didn’t even realise how bestial he started acting. He stomped his fore hooves with two loud clops, which reminded him of what he was becoming and only intensified his fury at the captors. Greg felt his ears twitch and grow warmer. Unbeknown to him they started changing and growing taller, more moveable atop of his increasingly equine head. His growing muzzle cracked painfully and made him shake his head in pain. His equine eyes were forced to move to the sides of his head slightly. His skull sloped down and squeezed in his human brain into a considerably more compact size. Meanwhile his collarbone cracked into a more feral shape, the base of his neck was forced to change position on his equine torso and his neck started to painfully lengthen and thicken. Greg swayed his horse head in reaction to the changes and he realised his neck has gotten more flexible. Most of his human teeth started growing bigger inside his equine maw and moving backwards. While his incisors widened and stayed in front of his maw. With the last growth spurts of his huge muzzle his tongue started lengthening to fit it as well.

Greg looked at his reflection again, which wasn’t really his at all anymore – A stallion’s head stared back at him with awfully conscious look, it was clear a human was trapped inside the almost fully equine body. Greg closed his equine eyes in grief as he felt the remaining changes wash over him. His stomach bloated out a bit as his intestines grew larger and fit for a tough herbivorous diet. His upper legs slowly finalised changing as his pelvis cracked. Greg shut his big eyes tighter as he felt a bizarre shift happening to the end of his digestive tract. His anus was forced into a higher position on his muscular butt, right beneath his swishing tail. Even that change of him wasn’t spared and Greg shuddered as he felt it change texture and size to be fit for his big body. Worse yet his hips started inflating in size to fit his muscular flanks. Those changes forced his equine butthole into a more exposed position as his flesh stretched. Greg didn’t think he could control his newly grown tail, but the humiliating changes made him press his tail against his shameful cleft instinctively.

Greg’s body finally settled down as it reached its final size, but there was one key part which made Greg whinny and realise he lost his human voice a while ago. His mostly human cock hanged limply between his powerful hind legs, because it was forgotten until now. Greg’s eyes widened as he felt his manhood start to shift into equine shapes and proportions adequate for a stallion. The sudden throbbing and warmth in his equipment made it erect. With each heartbeat his cock started to grow bigger and deforming into a more bestial shape. His human foreskin receded and a medial ring formed on his fattening cock. Greg shuddered feeling all those changes too well, he craned down his neck and looked beneath him to observe the changes better.

Just in time to watch his round cock tip flatten and flare out into a distinctly equine shape. Loud clops were heard across the chamber as Greg positioned himself better to watch the grotesque changes of his growing member. The flesh on it darkened and made it look even more equine than human. He felt parts of his cock flesh fuse to his stomach and he realised an equine sheathe formed for his stallionhood. His massive cock swayed around eager for action as it finished lengthening to its final, impressive size. Greg gritted his thick teeth as he felt his balls swell and weight his darkening ballsack down. His new equipment seemed so bestial and alien, but it was his own now – Greg realised. His human life just ended and it depressed him, but the longer he stared at his shaft the more thoughts he had of masturbating his worries away since he was becoming a simple animal anyway, he felt like he had no better way of getting rid of the stress temporarily.

His continuing changes made up the decision for him catching him off guard. His thick hide started to itch all over his body and Greg realised what his stallion body missed – The fur and horsehair. That realisation broke the mood and Greg felt his shaft pull upwards towards the dark underside of his belly into a newly formed sheath. He snorted and decided to just endure the last of his changed calmly. Glossy midnight black fur started to sprout all over his body, covering it and making it look more natural with the short pelt of fur. Greg felt longer hair grow and weight down his tail a bit. Similarly a black mane sprouted from the top of his head, replacing the leftovers of his human hair completely. The luscious mane grew all over the top of his neck from his equine poll to the withers. His fur finished growing and with that Greg became a black stallion completely, with no traces of his humanity left – Except the eventual ones in his behaviour as his consciousness was left in tact from the looks of it.

“The procedure proves to be a success. Subject #104, if you comprehend what I’m saying know that after we perform necessary tests on your new form we may allow you to live a peaceful life adequate for your new species. Resistance is futile, the procedure is irreversible as it should. You don’t have to like your new form, but you have to learn to live with it and for now comply with our orders during the tests. Understood?” – The same voice from earlier boomed from the speakers. Greg shuddered his ears hurt from the loud speaker, but he understood his grim situation and with no better options he neighed and nodded his big head while trying to keep his balance unused to standing on all fours. “Good stallion, glad you comprehend your situation. Alright, let’s move on people – Initiate stage two, the standard tests for the subject’s sanity…” – The man from the speakers continued. Greg sighed and tried to learn how to move more swiftly on his four legs, he felt like his changed brain tried to guide him in that matter, but it still wasn’t a banal task. One way or another, he slowly came to understand that there was no way back to his previous life…
