Eriko, a mother who treats her son as a child forever. One day, at a drinking party, she got into a fight with her son who came home late at night. "I'm already 20 years old! Don't treat me like a child forever!" Eriko visits her son's room to apologize, but she accidentally meets him while masturbating. And Eriko said to her son, "It's okay to make up, but show me her mother's tits."
