Madoka, a housewife living peacefully with her son and husband. Thanks to her diligent upbringing, her son grew into an honest and obedient man. On the other hand, Madoka was a mother with a strong sex drive, and she couldn't satisfy herself with just her husband's sexual life, spending her days masturbating whenever she found the time. One day, her son caught her in the act. Frustrated, her son forced a female student into sexual acts at school, causing trouble. Madoka thought it was her fault that her son had caused problems and decided 'I have to teach him...' and began giving her son sex education.
