In order to fulfill the wishes of the client who wishes to have sex with his close relatives, Takeshi Karaki stands up... Voyeur of the whole incest plan! A request from my son who wants to take revenge on his mother (47 years old) who has been busy working as a manager and sacrificing her life with her family. A mother who is asked by her son to introduce a monitor at a massage shop for menopausal disorders, and receives a massage without suspecting that the therapist played by the staff is a fake. When the racy part is rubbed and the body of 10 years SEXless is on fire, the female genitalia is stimulated and the love juice drips and she faints in agony. A mother immersed in a wave of pleasure accepts SEX with her son, inserts it at the woman on top posture and carefully grinds her waist. The cock of the staff is also accepted and it is disturbed with a loud voice.
