Mary, annoyed at Brett, picks up two vials. The cow and the female ones. She takes the horse's head in her rubber paws tightly and opens his mouth. She dumps both vials right in. Brett recoils, but his inflated rump is already against the wall and he can't move backward anymore.
Mary dances back and watches as Brett gets his punishment. Not much really changes, or is that obvious. Brett's coloring fades from brown to black and white. His body remains the same, but with some slight adjustment. His once sleek and pointed nose becomes rounder and more blocky, and his tail becomes long and thin with a small inflated tuft at the end. The most notable change was below him. Brett felt his large horse penis simply melt back into him and a new pouch descend. His light pink udder inflated with three pairs of teats. It kept inflating until it reached a good beach ball size before stopping.
Brett mooed her dismay at being changed from a sexy stallion to a cow. Mary just giggled. "Well, if you're a good cow, Bessie, I'll change you into something good, OK?" Mary pats the head of Brett.
