Julie la douce (1982)

Julie is cycling along a country lane when she is knocked off her bike by Edouard's limousine. He and his chauffeur pick her up and take her to his mansion to recover. Edouard's wife, Louise, is out and the maid, Ingrid, is dusting a high shelf. Edouard cannot resist groping Ingrid and then going down on her as she lies on the table. He gets the chauffeur, Armand, to join in for a threesome. Armand cums first, giving her a facial, and then Louise arrives home. Armand helps her with her bag and presses a buzzer to warn his employer of his wife's arrival.
