You cower as you look up at the cowgirl over you. You're not liking this one bit! You moo to protest, but it doesn't seem to move your former girlfriend.
The cowgirl over you gets an evil gleam in her eye. You know something very bad it going to happen. You bleat and look around for an exit. But there isn't one. So you move as far from the cowgirl as possible.
"Genie," she says, "I wish to add the equipment of a large bull to me." She grins down at you as the genie does him magic and begins to change her.
Her once feminine body slowly hardens with a slight gain in muscle. Two horns emerge and grow out of her head, sharp and thick. But the place that you're watching is between her legs. Her bovine lips elongate and form what you know is a bull's penis. It thickens and swells, rubbing against the cowgirl's udder. Your cow eyes widen as the bullhood reaches a gargantuan size.
She moans, her voice slightly deeper. Her new bullhood is erect and throbbing against her full udder. "Oh! Now this is even better!"
She moos and moans.
