One day, the courier with whom she was having an affair comes and they have sex, but her father-in-law is once again peeping. Then, the father-in-law asks for his wife's voluptuous body, using the fact that he witnessed her masturbating and cheating on her. Her husband threatens to expose her, and she can't refuse and opens her crotch.
