Price Racinghorse Dusty-Rose was glad she could rest for the weekend. Dominique, her rider, and she won a price in a dressage-competition. After they came back Dusty-Rose enjoyed it to stand in her stable. Unbeknownst to her and her rider, an infected female rider had her transformation, into a muscular and horny himbo, in Dusty-Rose’s stable and dumped heavy loads of infected precum in the watering hole and came in the hay, that lay in the stable as feed for the horse.
After Dominique left Dusty-Rose shook her brown furred body and went to the trough to refresh herself. Unbeknownst to everyone the Himbo-Virus mutated so that even animals could get infected. And after Dusty-Rose drank the contaminated water, it suddenly happened.
She started to sweat. Suddenly her body began to shake and Dusty-Rose let out a loud neigh. While shaking her wet pussy starts to get dry. And while getting dry it starts to close up. On the other side, while her pussy closed up between her hind legs a sheath and a scrotum started to form. And suddenly the starting hornieness Dusty-Rose had, from drinking the stained water, mad her new male organ erect and her new cock suddenly fell out of her sheath, her ovaries turned into balls and fell in her scrotum, and her pussy finally closed down forever turning Dusty-Rose the mare in Rusty the Stallion.
Suddenly Rustys body stopped shaking and he began to shoot jet after jet of cum out of his new cock. “Ne----i-----gh Shi-gh-t I-gh’m cumm-eigh-ng.” Rusty shouted. After his orgasm subsided and Rusty calmed down, he suddenly said “What is happening to me? Why am I a stallion? And why the hell, can I talk?”
While he wondered that he can talk Rustys hind legs reformed and give him the ability to stand upright. After he felt the changes Rusty took all the force he had and raised his body. While raising the body, it transformed too. His horse body started to shorten and reform into the muscular body similar to a professional heavyweight bodybuilder. And his Forelegs transformed into arms matching to his body while his hooves split into three-fingered, hoove-nailed hands. And after all Rusty’s horse ass started to puff out a bit, to invite another cock to fill his ass.
Finally fully tansformed into an anthro-himbo-stallion Rusty grabbed his flaccid cock and starts to stroke it until it is hard again. While stroking Rusty thought “Fuck those sucking dressage competitions, I am so powerful, I will attend weightlifting competitions soon. Damn, thinking about that makes me so horny” and jerked off faster and faster. Suddenly his balls were lifted up and with a loud neigh he shot another load messing the stable floor. But even after Rusty came he was still hard and he thought “Still horny, what should I do now?”
