The old woman just smiles, "Well then, we'll have to do something about that!" She makes a slight motion with her hands, then sits back and smiles.
"What are you HEee-haw!" you say, covering your rapidly expanding muzzle with your hands. "Hee-haw!" you say again.
The woman smiles, "You'll make a fine addition to the stables. Much better than the Jack you might have been."
Even as she says that, your clothes rip from your expanding body. You look down to see that one part of you isn't getting larger, though. In fact, the only thing
down there that is growing are teats!
Moments later, you fall to your forelegs and feel your body fill out. You stand there in shock as the old woman runs her hand down your neck. "There, now there's
another female here!" she says smartly.
