Akari, who serves as the student council president at a prestigious girls' school, spends her days as a model student, setting an example for her peers. One day, she is summoned by Nakata, a teacher, under the pretext of providing extra tutoring for her application to a top university. However, Nakata ends up coercing Akari on the spot. From that day on, she is called out during classes for fellatio, and even engages in orgies with other teachers. In the end, she is thrown into a circle of part-time students, subjected to relentless debauchery.
