Her head felt heavier than it should've been. She coughed, wheezing, the start of a bray in her throat. "I don't...don't wanna be a donkHEEEEE!" Her chest barreled outward, swallowing up her already-modest bust, as new teats sprouted below. It was getting harder to stay standing on two feet...on her hind legs.
