Cathy Howard is the blonde British bird bravely baring boobs and butt in Pete Walker’s 1968 sexploitation comedy School for Sex. But that’s not the end of the story for Cathy. Two years later she appeared in It's the Only Way to Go (1970), Permissive (1970), and Secrets of Sex (1970). Then, in 1971, Cathy got an uncredited role alongside titillating twin babes Mary and Madeleine Collinson in the famously X-rated Hammer horror flick Twins of Evil. Cathy has nice twins too.
