To Hex With Sex (1969)
Try this whacked-out skin flick on for size! A nerdy bra company worker is fired from his job and meets the devil. He gets one wish from the female Satan, which she promises will come true. He wishes to be a movie mogul and own his own studio, but even after making some sexy films, he wants another wish fulfilled. Only this time there will be hell to pay, as the devil needs her own sex slave. Stefan Peters and Paula Shaw star in this groovy sex farce.
