Kiko's son, Takahiro, thinks about nothing but ejaculating whenever he has free time. He is a sex monster. Kiko was troubled by her son who sees even his mother as a sexual object when he loses his reason. As she walked with her head in her hands, she encountered her son's childhood friend Moka. When Kiko consulted Moka about her son, Moka, who is famous locally as a slut, offered to handle Takahiro's sexual needs out of concern for him.
