To fulfill the client's wish of wanting to have sex with a close relative, Takafumi Akagi rises... Secretly filming the incest plan in its entirety! Director Koichi Takahashi responds to a request from a son who has lived with his mother as a single parent. As a friend of the son, he makes contact with the mother, and after a feast with the three of them, the director brings up a certain proposal. Asked by the mother to deflower a virgin acquaintance, she agrees, stops the director from leaving, and kisses him. The mother, moaning and reaching for the director's hips as she accepts his manhood, is deeply moved. On the day of the deflowering, the blindfolded mother has sex with the son, disguised as the virgin. Teaching him how to handle a woman, she lets him tease her sensitive spots, making her moan. The mother panics at the son's voice revealing the truth, but the director convinces her to resume sex for the son's sake. Overwhelmed by the son's erection, she cries and gasps.
