The protagonist is called to the school nurse's office by Momoka, who coerces him into engaging in various sexual acts against his will. After this encounter, he accidentally stumbles upon a private moment when he witnesses Momoka's younger sister, Maron, masturbating in a secluded area. Maron catches him watching and, instead of being embarrassed, takes control of the situation by stripping him and using her hands and feet to stimulate him. Their encounter escalates, and he ultimately takes her virginity. Later, the three of them—the protagonist, Momoka, and Maron—visit a public bathhouse together. What begins as an innocent outing quickly turns into a threesome, as the sisters involve him in a shared sexual experience that blurs the lines between coercion and consent.
