Jean Desvilles – Les Plaisirs Fous (1977)
Jacques has lots of mistresses and his wife, Chantal, doesn’t seem to mind. In the first scene he has dinner and sex with Martine, a brunette (Maryline Guillaume), his former secretary, who hands him a photo of her replacement before they amke love. Then he goes home and has sex with his wife, Chantal. He attends a brothel (or maybe it’s a swingers’ club) and has sex with a busty brunette (Jocelyne Clairis) and is then revived by a blow job from Brigitte Lahaie. At work his new blonde secretary, Caroline, resists his advances at first then succumbs. For their second assignation he takes her to the brothel/club and persuades her into a threesome with Brigitte Lahaie. Then he takes her to meet the wife and they have another threesome. Then they all three plus Richard Lemieuvre go to the brothel/club and meet Alban Ceray with a blonde (Veronique Maugarski). An orgy ensues. Then Jacques takes his wife and mistress/secretary to spend the night on a fishing boat. Who knows why?
