A group of five female students and two male students participating in an art club retreat, along with their supervising teacher and a new young female teacher named Haruka. After a meeting to present their daytime sketches ends, they begin cleaning up in the kitchen. At that moment, a male art club alumnus approaches Haruka, the assistant teacher, and sexually harasses her by groping her ass from behind. Despite her protests of "Stop it," she gradually gives in to his aggressive advances and starts kissing him. The alumnus then says, "Let's go to my room, teacher," leading her away. In the room, another male art club alumnus—a college student—is already present, with a female art club student on all fours giving him a blowjob. It becomes clear that everyone connected to the art club, regardless of age or gender, harbors erotic allure. At the retreat house, two male art college students, the female teacher, and the female students are all caught in an intense orgy, surrounded by cocks and moaning passionately. Their pure white skin, pink nipples, and pussy lips are stunning, and the sight of the girls rolling their eyes and climaxing repeatedly is so erotic it'll make any viewer jerk off. Enjoy.
