A new wife (Edwige Davis) proves reluctant to indulge in the kinkier aspects of sex, i.e. blowjobs. Her husband has made arrangements, however. He leaves on a trip and places a key to the outhouse in a draw, telling his wife she must not go there (I deduce). She succumbs to curiosity though and goes to peep in. She sees Chantal Virapin masturbating. She masturbates herself while she watches and then runs for the key, goes in and joins the girl for a g/g session.
