"I think Kokoro to explore pleasure is stronger than anyone else's," says Masayo Miyashita, 50 years old. She is a full-time housewife who has been married for 20 years. She is very Kokoro and has tried various forms of masturbation, and is currently searching for the ultimate pleasure. However, her husband cannot keep up with Masayo's passion, and their relationship has stagnated. His eyes naturally turned to the outside of the home. What Masayo wanted was a man with a big penis who seemed to be good at sex. Then she suddenly realized that that was just like an adult video actor. It didn't take long for her to decide to appear in the film. Watch as this greedy, pleasure-seeking fifty-year-old wife experiences the hospitality of the best actors and trembles with tears of joy as she orgasms repeatedly.
