JUQ-330 There is only one member, and I am the only advisor. After school alone, I seduced a student and had sex over and over again. Mariko Sada

Mariko has a conflict with her school over a bullying issue and is assigned to a new post far away. At the newly appointed school, he becomes an advisor to the art club where only club member Kuroi is enrolled. One day, while heading to the clubroom, he sees Kuroi being bullied. Despite Mariko reprimanding her, the situation doesn't change. Mariko, who is a mixture of pity and love, crosses the line with Kuroi in the clubroom after school.
