A self-proclaimed "lover of married women's hearts," AV director Takahashi Hirokazu invites his wife's friend over to stay at their home under false pretenses. As they spend the night together alone, there's no denying that something naughty is going on... The woman visiting Tokyo, Satsuki, is a 38-year-old housewife married for eight years and has one child. She's enjoying some time away from her family when she takes a shower in an empty room, unaware that her host, Hirokazu, is watching. When misunderstandings are cleared up, they share dinner before retiring to bed. Their conversation turns sexual, and Satsumi opens up about being groped on the train earlier that day. This triggers a playful exchange where she becomes increasingly aroused by Hirokazu's touches. Unable to resist any longer, she eagerly accepts his penetration and moans in pleasure as they passionately make love throughout the night. In the morning, exhausted but satisfied, Satsumi falls back asleep while Hirokazu watches her from afar. Later that day, he catches her masturbating in front of him and decides to join in on the fun. Together they indulge in another round of passionate lovemaking, this time with even more intensity than before.
