A married woman who has been married for three years lives with her husband's father. Her busy husband is often away on business trips, so the frustrated wife masturbates without any marital activities, but her father-in-law watches and grins at her. One day, the courier with whom she was having an affair comes and they have sex, but her father-in-law is once again spying on her. Then, the father-in-law seeks his wife's voluptuous body, using the fact that he witnessed her masturbating and cheating on her. When she is told to tell her son, she opens her crotch and cannot refuse. Furthermore, she is made to cum many times by her stepfather who hates her at night.
