Man into Female Horse Transformation Story | Unwilling | NSFW | 3rd PoV | Painful

John was addicted to gambling and sometimes it worked for better or for worse. He spent at least few days a week watching horse race and naturally bet for the ones which had the highest win-rate.

One particular day a shady man came up to John and offered him a bargain. If the horse John bet on would win, the shady man would make him rich. However if the horse wouldn’t win the consequences would be dire in price. John imagined that he’d have to pay double the price he’d win or something similar.

He had no idea how wrong he was, but would soon find out as the horse he bet on lost the race. “No! I can’t believe she lost… How?” – John muttered as he came down the tribune. The second he did the same shady man appeared out of nowhere and shook his head in disapproval. “Mr. John, I really hoped your expertise would lead to a better outcome, but deal’s a deal. Please come with me.” - The shady man said.

John hesitated, obviously not wanting to even hear the unimaginable price he’d have to pay for his mistake. Albeit then he noticed some two men observing them from a distance, they looked like buffed bodyguards. John gulped, hanged his head low and followed the shady man obediently. During the walk and talk John found out that the shady man’s name was Smith and that he had a herd of his own racing horses.

The two approached the stables which scared John a bit. Would he be threatened in there to pay up as fast as possible? “… So a deal’s a deal, I’m sorry mister John.” – Smith said as he quickly injected John with something and then pushed him hard onto the hay filled interior of the stables. “Ow! Hey! What the hell was that for? We didn’t even discuss the price…!” – John groaned distressed as he rubbed the injection area which started to swell a bit.

“The price? We agreed it would be a high one and so it is – You’re becoming my newest broodmare. I’d take the clothes off if I were you.” – Smith said nonchalantly. John just stared back at him with gaping mouth. “What?! You didn’t specify that be-agh! Oh shit, this can’t really be happening. My feet, my hands – They ache like hell…!” – John mumbled as he leaned his back against the hay bales and started taking off his shoes and socks.

He regretted the action when he realised how far gone his feet were already. His middle toes were fattening up and elongating grotesquely, while all the other toes were slowly shrinking and getting reabsorbed into his flesh. John held up one foot and felt in his fingers how his toenails started to swell into shapes of strong hooves. He dropped his foot in dread and it landed on the planks underneath with a loud clop as it was already almost a fully developed hoof.

John ignored the fact that Smith was watching the scene with the slightest smile, he was too focused on his changes of how real they felt. John felt his entire body swell with mass slowly at first, but the pace was quickening and John’s clothes were getting too small to contain his shifting body. The man gasped as he felt his spine crack and reform, force him to tilt forwards. His back was broadening altogether and his hips were widening and forcing his legs to spread some.

“This is a nightma- A horrible dream, I must wake up, I mu- Ahhh!” – John cried out in distress before finally collapsing onto all fours. His hands caught his growing weight. John stared down at his deforming hands. His middle fingers were thickening immensely and growing longer than the other fingers, which slowly started to retreat back into his hands and disappear completely. Nails fattened up and encompassed John’s remaining fingertips forming solid hooves. John regretted the bet, it was the biggest mistake of his life to not even ask for the specific price – Which he was now forced to pay up in humanity.

John’s body was forced to thicken in many areas and it grew altogether continuously. He closed his eyes in discomfort as he felt his jeans slowly split at the seams, unable to hold his massive ass anymore. John gasped as he felt his pants tear apart along with his underwear and fall off him revealing his increasingly equine rump. The bones of his body elongated, mainly his limbs which slowly gained animalistically athletic shapes. Despite being on all fours John was slowly growing taller than Smith who stood nearby and continued to enjoy the scene.

John groaned in discomfort as he felt his spine start to elongate and put pressure in his neck and tailbone at the same time. The tailbone started to push out and grow into a stubby tail, but more vertebrae quickly formed and the new appendage started to sway sideways instinctively. “A fuckin’ tail… This is really happening. At least make me a stallion damn-heeeight…! Did Ieeegh just…?!” – John whinnied in horror as he felt his neck swell with muscles and elongate to give his body an overall more equine shape.

Meanwhile Smith made a few calls to his accomplices and walked around John’s growing and increasingly horse-like body. “Sorry buddy, but this has to go.” – Smith said as he pointed at John’s genitals which were growing bigger and turning into those of a stallion. John managed to turn his head back only to feel a jab of a syringe to his hip. Realising what was going on John tried to kick his tormentor, but Smith easily dodge the hits as he pulled out the syringe. “Your moves just help spread the serum better, hah.” – Smith said as he backed away from John, who froze in fear at what he heard.

John didn’t dare to move even when he felt his nipples start to swell and rub against his extremely strained shirt. He felt fat build up underneath them and already knew that his fate as a broodmare was inevitable. John suddenly felt pressure rise in his chest, which pushed air out of his expanding lungs. He struggled to breathe for a moment until he desperately inhaled air and as he did his ribcage expanded some and forced his shirt to finally explode. His fatty, darkening breasts plopped out of their confinement and started to migrate downwards between his hindlegs. As they did they moved closer together and fused together in the middle forming a dark horse udder with two puffy teats.

John moaned in a strange manner – His voice was somewhat deeper and yet undeniably feminine, but most of all it was prominently equine. He tried to pitifully beg for help, but his words were incoherent mess. “Shh. You’re no longer a human to be allowed such luxuries.” – Smith taunted staring into John’s eyes as they began to alter and bulge out. John blinked as he felt his vision alter, his pupils started to expand sideways and become equine. If not for the feelings of arousal between his legs, John would stomp his hooves and maybe even try to fight his captor.

Instead John stared cross eyed as his face started to swell and fatten up. His nose began to widen considerably, stretching his nostrils into wider shapes. His entire skull ached as it began to change into the massive equine shape. His ears started to thin down and move higher on his head. At the same time they began to stretch into distinctive, equine points. His lips plumped up and became somewhat more flexible to allow him better access to food and recompensate the loss of hands somehow. John felt his teeth swell in his gums and a gap form between his incisors and molars as his dentition was becoming decisively that of a herbivorous horse.

John gritted his swollen teeth in pain as his skull began to flatten at the top, forcefully squeezing his brain into a smaller shape. John wasn’t even able to scream at this point, just neigh at the top of his ballooning out lungs. His face started to push out into a broad horse muzzle. Bones expanded and stretch was forced to stretch. John tried to catch his breath, but was only allowed to once his muzzle finished growing. The pain was gone, but John realised that his human visage was twisted completely into that of a simple horse, probably with no option of going back.

John hanged his head low in sorrow, ignoring the discomfort in his chest as it slowly finished barrelling out and expanding. His body spasmed slightly as it grew even bigger and slowly reached its final size. John’s tail twitched as its growth reached its final length. It slapped his muscular ass and… Something else. John whinnied loudly when he realised that his genitalia migrated closer to his anus. And yet his balls were fighting to squeeze through John’s thick buttocks and enter him.

John stomped his hooves in panic as he felt his testicles shrink and churn – They began to reform into his ovaries and the sensations were nauseating. With off-putting slurps his ovaries shot deeper inside of him and the sensations made John instinctively rise his tail. His ballsack was now empty, but despite that it started to shift and darken. Become velvety in texture and form a cleft down the middle, behind which a tunnel started forming to the John’s developing womb. With an orgasmic feeling the dark, puffy flesh parted and split down the middle forming a gaping equine snatch, which immediately began to squirt feminine pleasure juices and wink from the transformative stimulation.

John closed his eyes and regretfully enjoyed the sensations coming from beneath his tail. His cock twitched and leaked out the remnants of his human cum as it kept shrinking. It was inevitably pulled closer and deeper between his dark equine pussy lips. His cock was throbbing hard, but despite that it was losing its phallic shape and slowly began to resemble a clitoris of a mare. John spread out his legs as he felt the clitoris slide into his pussy and nestle inside. His teardrop cunt puffed out to signal readiness to mate and with that John was officially a mare now.

John felt the last changes wash over him. His skin throbbed as it darkened all over his body and turned into equine hide. His hide then started to itch as fur started to sprout all over his body. Stretching from his head to his back a majestic mane formed. His tail too grew longer horsehair that thankfully to him covered his shameful genitalia, at least for now. Slowly the changes finally came to an end as John the greedy human got turned into a chestnut thoroughbred mare.

The confused animal looked around and realised that Smith was gone. In his place now stood a black stallion which snorted at the mare. John’s eyes widened as he saw the erection the stallion sported. A warmth blossomed in John’s groin and once again his tail lifted up, to the side this time. Dark, plump equine cunt John sported started to wink lustfully and the stallion apparently smelled the mare’s arousal as it came behind John and started licking his fat vulva.

John whinnied in bliss sheepishly, but when he turned his head back he noticed the stallion jump onto him. John stared wide eyed as the stallion positioned himself atop him and started to prod his ass with the blunt tip of his fat cock. In a matter of seconds he found his prize and in one quick motion stuffed John with his meat. John whinnied and thrashed around from the overwhelming pleasure as the male started thrusting in and out, prolonging the ecstatic moment. Until his hot rod started to pulsate inside John’s virgin mare cunt and shot loads of hot cum inside him. John came quickly after and his strong pussy clasped at the cock many times, before slowly calming down.

The male dismounted John and nibbed at his mane in appreciation. John’s confusion disappeared and was replaced by hope. Maybe his new life wouldn’t be so bad after all…?
