You begin to worry about what happened next, while your uncle grew bigger than his usual height. You could also see Jon's feet becoming longer, while his toenails began to fuse, and harden, becoming a bovine hoof. Just then, you see Jon get an erection, as he reveals that his penis has become more bovine shaped.
"Let's see if you're any good at milking a bull," Jon says, as his face began to push out into a muzzle. Black fur covered up your uncle's body, as his hair fused along with it, and the fingers on his hands began to fuse just like his toes, a the nails hardened becoming long bovine front hooves. Your uncle was becoming a bull, and not only that, but you feel his penis begin to spit out precum all over you. You decide to leave, but once Jon was finished changing, he charges over, and begins to bite down on your shirt.
