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 it rare for a couple to have such an age difference. However, he is very active and full of energy, so you would never notice his age. However, when it comes to sex at night, he does show 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 does not mean that she can cheat on him, so she continues to hold back 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 about the DVD, she discovered her husband's unexpected hobby. "Actually, I want to see you in the video," he said, begging her to appear in it. And then, frustrated with her sexual frustration, she finally made up her mind.
