Mizuki, a married woman living in Nagoya city, is 34 years old. She married a man 15 years older than her, whom she met at an English conversation class, and lived in the United States during her newlywed days. Perhaps because she is a year away from her husband, the couple's activities are completely different. However, she is so greedy for eroticism that she herself has a desire to be tied up and bullied by the historical drama she saw when she was little. At first she was nervous, but when she touched her body, she felt nervous and she began to ask for a thick piston by herself.
