AV Director Koichi Takahashi, who calls himself "Married Woman's Heart's Lover," invites his wife's friend to stay at his house with lewd intentions. There's no way a married woman spending the night alone wouldn't be affected... Makoto, 32 years old, married for 7 years, housewife. The landlord returns home while she's naked before showering, leaving the married woman flustered. Relieved to understand the situation, they share dinner and relax. The director, who fell asleep with only a bath towel wrapped around his waist, is teased... Entrusting her body to the awakened director, she sucks on his penis again and accepts insertion, moaning intensely. After bedtime, the married woman caught masturbating orgasms with a toy, feeling so much she ascends. In the morning, she asks for his penis again, is thrust into violently, and cries out loudly.
