Koichi Takahashi, an AV director who calls himself the ``lover of a married woman's heart,'' lets his wife's female friend stay at his house with ulterior motives. - There's no reason why a married woman who spends the night alone with her has nothing to do with her... - Raie is 45 years old, married for 16 years, has no children, and is a gym instructor. - Just as the married woman, who often talks to herself due to the novelty, is relaxing in her room, the director returns and panics. - After the situation was explained, the married woman, who forgave herself after having a discussion about the camp and being served grilled meat, got excited by the dirty jokes. - The married woman, whose lust has reached its peak as she grips the director's penis, rolls up her clothes as she is told, accepts his caresses, and writhes in agony. - "It's in! It's in!" When the penis was inserted, she kept saying obscene words and fainted in agony. - In the middle of the night, I was attacked in my sleep and I was shaking my hips in a dreamy state and ascended to heaven with a toy. - The next morning, the married woman in heat continues to cum due to the stimulation of the penis.
