I am a witch who specializes in transformation spells. I can change your height, age, facial features, hair color, etc. I could even perform some more fantastical transformations, like turning you into a vampire, turning you into a demon, giving you hooves, giving you a tail, or allowing you to breathe fire. However, there's one catch. Everyone I transform seems to get a little bit fatter, with a softer gut, wider hips, and bigger tits. I'm looking for a test subject to help work out this kink.
