To fulfill the wish of a client who desires to have sex with a relative, Karaki Takeshi steps up... The entire plot of an incest plan is captured on hidden camera! A 53-year-old mother who peeks at her son in the bath, overflowing with both sexual desire and affection. She decides to show her son where she receives erotic massages and involves him in the process. The mother comes to receive a massage from an acquaintance male while accompanied by her son. She exposes her slender body and moans intensely during the extreme treatment, all while her kind-hearted son watches in concern. She shows and lets her son touch her wet female genitalia, then lovingly sucks his erect penis and invites it into her vagina. As she also accepts the massage therapist's penis, the mother reaches orgasm continuously.
