Self-proclaimed "married woman's soulmate," adult video director Koichi Takahashi invites his wife's friend to stay at his house with ulterior motives. Spending the night alone with her, there's no way the wife is innocent... Seiko, 32, married for seven years, a full-time housewife. The landlord returns home completely naked, having just showered, and the wife is flustered. Understanding the situation, she is relieved and they have dinner together to relax. She plays a prank on the director, who falls asleep with only a bath towel wrapped around his waist... When he wakes up, she gives herself over to him, sucks his penis again, and moans as he penetrates her, saying, "I want to put it in." After going to bed, the wife is caught masturbating, and with a toy, she feels so intense she "goes crazy" and reaches orgasm. In the morning, she begs for his penis, "just one more time..." and writhes loudly as he thrusts violently.
