AV director Koichi Takahashi, who calls himself "the heartthrob of married women," invites his wife's female friend to stay at his house with ulterior motives. It's inevitable that something will happen when a married woman spends the night alone with him... Tamami, 38 years old, married for 8 years, one c**, a full-time housewife. The married woman, who came to Tokyo to meet a friend, undresses to take a shower in a spare room, when the homeowner, who wasn't supposed to be home, appears... The misunderstanding is cleared up, and after dinner, the conversation turns to sex before going to bed. She reacts sensitively to role-playing after hearing about being groped on the train. The highly sensitive married woman writhes her hips and breathes heavily, and when she can't hold back any longer, she sucks his penis and accepts penetration. They intertwine intensely, repeatedly saying how good it feels and screaming in ecstasy. In the middle of the night, she is caught by the director while pleasuring herself, and the next morning she attacks the sleeping director and plunges into a world of pleasure.
