Her husband has had erectile dysfunction since giving birth to their only son, Ataru. Misa has been feeling lonely for a long time, and can no longer bear the loneliness, so she ends up having sex with her only son, Ataru. Unlike her husband who has erectile dysfunction, Ataru is young and has a ``virile streak''. Misa's sexual desire is not satisfied, but rather she desires it even more than before. Meanwhile, Misa, who has been ``put on hold'' recently, explodes with her pent-up sexual desire and forces Ataru to do three consecutive shots without pulling out!
