Witch Academy (1995)

Members of an exclusive college sorority (where sadomasochism seems to rule the day) seek twisted new ways to humiliate a new pledge named Leslie Perkins, who they feel will never, ever fit in since she's something of a nerd and a prude. However the Devil has other plans and helps transform Leslie into a bodacious babe smokin' as all Hell. Only why is the Devil helping Leslie? You just got to know he has ulterior motives in mind.
