Marcus was sleeping peacefully until he heard an odd stream sound near him. He thought that someone was in the restroom or maybe a faucet was open. Hr didn't mind but after some seconds the sound was getting annoying.
He opened his eyes in order to look what was going on but he was surprised by what he saw.
He wasn't in his cabin anymore. He was in a stall full of hay and a unmistakable smell of barn. Next to him were a few horses and opposite were some more. He was scared, someone has made him a prank and moved him to that stall while he was sleeping, he thought.
'I must find a way to escape.' He was thinking when he heard that stream noise again. 'Where does that sound come from?'
He looked around him until he found it. The horse next to him, a stallion for sure, was pissing just a few steps from him. The animal didn't mind its piss stream was making such a mess under him and a puddle was growing between its paws.
On the other hand, Marcus was absolutely disgusted. Not just by the rancid piss smell, but because that horse was sporting its disgusting shaft meanwhile. That black long and thick thing brought bad memories to him.
Marcus tried to ignore the stallion when the one on his other side began to piss too followed by another one and other and other. Marcus wanted to puke as the horse were unfolding their sheaths and their big dicks began to piss.
"So that's why they said piss like a racehorse." A woman voice said and quickly Marcus found it was Jeanie. "And you, Marcus? Don't you piss like a racehorse too?"
'What are you talking about.' He tried to say but quickly realized he can't talk. A loud whinny came out from his mouth instead. That's when he found out what's going on. He was a horse too!
"As a former human boy you just turned into a colt." Jeanie said. "Do you want to be a stallion?"
Marcus neighed but in disapprove and started shaking out of control. Jeanie just smiled and snapped her fingers. Slowly, the colt turned back into a human. Marcus was back, although he was naked in the middle of the stall among stallions.
"Come, Jeanie. What's your problem?!!" He yelled at her.
"I turned you back in order to do this." Jeanie grinned and snapped her fingers again.
Marcus felt a sudden pain in his stomach. He was getting a painful growth, he can feel his bones restructuring and elongating, his hands and feet getting bigger and muscle mass appearing on his former skinny body.
Jeanie's magic was working quickly on Marcus' body. His butt pumped and his balls dropped and grew along with his dick which gained a respectable 6 inches length and healthy thickness. An Irritating itching was spread through his body as hair began to come out his from his legs and arms. His crotch and armpits were specially irritating as curly pubes were growing out of control on there. Finally, a treasure trail and a thin beard were the last to grow on him. Now, Marcus was a hairy young adult, still naked and among stallions.
"You make me older." Marcus said in his new deep voice.
"You look good, Marcus." Jeanie smiled. "Those hairs make you look manly and handsome." She peeked at Marcus' new manhood and when he realized that she was seeing it he covered it with his hands embarrassed. "Nice set. Perfect for a stallion."
"What?! No, please, no!! Don't turn me into a horse again!!" Marcus begged but it was useless. Jeanie had snapped her fingers.
Marcus already thick legs grew way more thicker as they turned into horse ones. His feet which had grew to a manly size 13 melted into hooves.
His juicy bubble butt swelled slowly into abnormally huge proportions. Definitely it was a stallion ass. Huge and strong. His anus moved upward until it took its new position. It farted uncontrollably all the way embarrassing Marcus even more.
His stomach barreled as his internal organs reshaped to horse ones. His lungs, bowels and stomach weren't human anymore. His shoulders followed as they changed and his arms transformed. He tried to hold his fingers in the ground but they quickly melted into hooves.
He screamed in pain when his tail began to come out from his spine. To add even more pain, his neck wad thickening and elongating at the same time. His screams turned into loud neighs as his face pulled outward. His eyes changed and moved to the sides. His mouth was in a killing pain when his teeth began to grow into large horse ones before his jaw grew accordingly. His ears got pointy and moved upward. His nose grew long and goofy as it turned into a muzzle. At the end, his tongue swelled huge as a soda bottle.
He was a hairless horse now but that didn't last too long. An infernal itch spread throughout his body. Brow fur covered the naked human skin turning it into a horse one. Long black hairs grew into his mane and his horse tail which he was unconsciously waving from side to side. Finally, he was a complete stallion.
"You 're a great stallion, Marcus." Jeanie said. "In all my years turning men into horses, I hadn't seen such a magnificent specimen!"
Marcus just neighed annoyed. He can't do anything else.
"You can see it, but I made you extra hung." Jeanie winked. "Let me show you."
'No, no, no!' Marcus panicked in his mind but it was useless. Jeanie's magic was making him unfold his shaft. He was disgusted just by thinking of how it should look right now. A black monster, over two feet length and thick like a boy's arm.
He had investigated about horses since his last experience. They dicks were always hard but they hide inside his sheath. Ugh!, he remembered. He has a sheath now too. A smelly and disgusting hole. It's made of my foreskin? Where does my dick hides when it's not unfolded? He questioned to don't think on how disgusted he was.
"Those balls are so big and squishable!" Jeanie said as she held Marcus' testicles in her hands. He felt some pain but it was nothing compared to the embarrassment he was feeling. "You still have some human sperm. Release it." And like an order, Marcus ejaculated an small amount of cum. A big load for a human but pathetic coming out from a horse dong. "Now, make horse semen! I want a lot of Marcus' babies."
'What?! No!!' Marcus screamed in his mind but he already felt how his balls were working on producing horse semen. He was really disgusted. There wasn't any trace of mankind left in his body. He was just a horse. Raised to make more horses like him. He wanted to cry but his face was expressionless. He must do something, he thought. He must fight back.
"Wow!" Jeanie said. "I didn't know you needed to go to the bathroom. You also piss like a race horse! Haha!"
'No!!' Marcus tried to stop but he can't until he made a big puddle under him. He didn't know what was more embarrassing. His incontinence or the pungent odor coming from his piss.
"Ok, you're done!" Jeanie smiled. "Hung like a stallion and piss like a stallion. You're one hundred percent stallion. Now, you need a mare to make you an authentic stud!"
