Carnal Madness (1974)

Three escaped convicts get more than they bargained for when they infiltrate a girls' school in Carnal Madness (aka Delinquent School Girls) (1975). This masterpiece of sleaze stars Michael Pataki, Bob Minor and Stephen Stucker as an odd assortment (we're talking a bad comedian, a horny baseball player and a psychotic fashion designer) of convicts who, after escaping from prison, make their way to a nearby private school for what they think will be an orgy of underage poontang. But assaulting these schoolgirls won't be so easy, because under the tutelage of topless teacher Sharon Kelly every one of the girls has been trained in martial arts. Carnal Madness will drive you SKINsane in your drain vein.
