Art teacher Kawakami and her assistant Shinoda frequently engaged in lesbian play within the school, hiding from other teachers and students. One day, Shihomi, a new student teacher assigned to this academy, was forcibly raped by the two under the pretense of art. Afterwards, Shinoda made Shihomi her exclusive sex toy, but Kawakami grew jealous. As they tried to drive a wedge between them, she ended up being raped instead. Vowing revenge, Kawakami and Shinoda and Shihomi, who mocks Kawakami. Thus begins the three-way lesbian battle.
