Yuuka Tada's husband was indifferent to her. They had no sex life. Yuuka was used to masturbating alone. One day, she was masturbating in the kitchen, and her son saw her. That night, after a bath, Yuuka went to the kitchen in only a bath towel. Her towel fell off, and her son saw her naked. "Are you trying to seduce me like this?" He forcibly raped her. From that day on, her son started demanding her every day.
