Shion-sensei is staying at Shota-kun's house, and he cleverly uses his position as a child to increase opportunities for bathing together. In the bath, they touch each other's chests and groins with lewd hands, gradually deepening their relationship. After bathing, Shion-sensei shows off her skills, teasing his body relentlessly and successfully bringing Shota-kun to climax. As her erotic nature becomes more apparent, Shota-kun grows increasingly interested, becoming unable to resist during massage sessions. Eventually, the teacher ends up hungrily going down on the boy's cock. Furthermore, Shion-sensei becomes aware of her own lustful tendencies, and Shota-kun forcefully makes her drink alcohol, getting her drunk and then using smooth, aggressive college-student-style seduction techniques. She falls completely for his advances, leading to an intense and passionate encounter.
