I had a boyfriend in my daughter around the age, and I was aware of a good relationship with my family. However, her daughter’s boyfriend seemed to have a strong libido and had sexual intercourse many times in her daughter’s room. She could hear it in Chisato’s bedroom, and even her husband muttered that he was amazing. One day, after returning from shopping, Chisato went to her daughter’s room to eat together, but she was not there and he was masturbating alone. Chisato was a little flustered, but he consulted with him about how he was in trouble because of his strong sexual desire.
