Self-proclaimed "wife's soul lover," AV director Takahashi Koichi invites his wife's female friend to stay at his house with ulterior motives. There is no way that the wife is innocent as they spend the night alone together... Keiko, 33 years old, married for 8 years, full-time housewife. While relaxing, a strange man enters the house and the wife is frightened, but when she realizes that it is the landlord, she is relieved and the mood becomes peaceful. After consulting about a certain matter, she is taught techniques to satisfy a man, and is made to hold his penis and kiss him. He touches her private parts and points out that she is wet, and she moans modestly. She moans as he penetrates her, and she writhes in agony as he penetrates her from behind, which she likes. She wakes up in the middle of the night and has her heated body comforted with toys, and in the morning the director wakes her up and plays with her body, poking her with his penis and moaning intensely.
