Ty spots a tall anthro stallion shoving his entire horse cock into a young man, neighing loudly as he helps turn the human into a horse like himself. Seeing this made Ty make up his mind on what he wants to be in this new world, and wish for himself to be turned into a raging hard stallion that was always horny.
The teenage boy groans as he starts growing in height along with his muscles gaining a strong, tone look. He stomps the ground violently as the change was like a weird pressure feeling but a pleasurable one at the same time, his feet turning into hooves causing the ground below him to be kicked up into mud. His cock expands till it was 18 inches in length and molts to form like that of a equines. Ty groans and laughs as he grabs his cock with both hands and begins to pump it. The other beasts around the transforming human joined in on the masturbating, grunting and growling with pleasure as some of them start fucking each one another as well.
""Y-YEEESSSSNNNNEEEIIIGGGHHHH!!" Ty cries out into the air as his face expands into a horse's, ears quickly forming and tail sprouting fast to nearly complete the transformation. Short fur sprouts all over his body and he starts cumming ropes of semen all over a jacking-off beast in front of him, neighing loudly as the change was finally complete and Ty was officially a stallion for the gay horde.
Ty shoots out his last ropes of cum onto the ground, his horse cock going half flaccid as he stomps his way to find man, woman, or anything to fuck. His past human memories were no more, and the only thing on his mind now was to FUCK.
