Koichi Takahashi, a self-proclaimed "lover of a married woman's heart" AV director, lets his wife's female friend stay at his house with a lot of ulterior motives. - There is nothing wrong with a married woman who spends the night alone. - Akiko is 28 years old, has been married for 4 years, has no children, and works at a resort hotel. - The landlord who should not be there to take her shower comes home. - A married woman who had no choice but to stay for dinner together consulted about the troubles of the couple's life when she learned that the landlord was an AV director. - I will be asked to practice how to invite her husband ... Kiss from body touch. - She inserts a meat stick erected by a married woman just a little, and reaches many times saying, "I'm in...". - When she finds late-night masturbation, she ascends continuously with toy torture. - As soon as she wakes up, she bathes in the morning sun and has sex.
