Jake approached the gate for Animalistic, a zoo where people were the animals. He had heard stories about it from friends and wanted to see what it was like. He walked over to a list and map of the wildlife areas he could explore, under each area was a list of the animals that people could change into in that area. He saw that there was a farm area with a horse option. So he set off.
After reaching the farm, Jake took a moment to look over the environment. He saw horses grazing and cows waiting to be milked. A dog herded sheep while various little critters ran up and down the trees. After looking for a good while, Jake went up to the terminal and selected the option for a horse. A message popped up telling Jake that the wait was four hours. Below the timer, there was a selection with virtually no wait; a hen, a donkey, and a dairy goat. Jake wasn’t really in the mood to lay eggs or go through a gender change so he picked the donkey.
After a short five minute wait, a man on the park staff came out and got him, bringing him to the changing room. The staff had Jake strip down to ready for the transformation. The staff pulled out a pre made serum and injected it into him.
The changes began with his feet, his toes turning black and melting into hoofs. Fur crawled up his legs while his knees began to shrink and bend backwards, making Jake shorter. Soon, Jake’s lower half was covered in fur as his ass swelled to the proper size for the donkey’s other name. Jake felt his tail bone unfuse as thin raggedy tail hung over his asshole. Jake then felt a heat grow over him, knowing what usually comes next. Jake’s testicles swelled as move back to hand between his legs, his shaft becoming erect as it lost most its girth yet get longer. The head became flat as Jake came, his body emptying out the human seed and replacing it with donkey sperm.
The changes went further up Jake’s body as his gut started filling out, fur covering the expanding stomach as Jake’s spine realigned forcing him onto all fours. His hands slowly turned to hoofs as his neck became covered in fur. His neck got a little longer and thicker as the final changes began. Jake’s ears elongated as they moved to the top of his head. His eyes moved to the side of his head while his nose flared and connected with his mouth. A snout started stretching out while Jake felt his teeth becoming bigger, much like a horse. The changes were finished and Jake was a full donkey. The park staff opened the shutter door and let Jake out.
Jake trotted out onto the farm, looking around. A man dressed in farmer clothes rang a bell and all the animals left. Jake followed them inside to find a trough of food. Jake didn’t waste anytime digging in.
