Miyanishi-san has been married for two years. Thanks to her husband's company, she says she has no financial problems, but there is one thing she is not satisfied with. In fact, her husband is 70 years old, making them a rare couple with a large age gap. However, he is very active and full of energy, so he doesn't seem to be old. However, when it comes to sex at night, she feels his age and says that he is not stimulating enough. However, her husband seems to be aware of this situation and has told her that he officially approves of her cheating. However, that doesn't mean she can cheat on him, so she continues to suppress her sexual desires. One day, while cleaning her husband's study, she discovered a DVD, and when she opened the case, she found an adult video inside. After that, when she talked to him about the DVD, she discovered an unexpected hobby of her husband. He begged her to appear in the video, saying, "Actually, I want to see you in the video." And so, frustrated, she finally made a decision.
