Tsubaki Kato and Yuzuha Hirai are close female teachers working at an all-boys school, secretly harboring a lesbian relationship. Though they've kept their feelings hidden in daily life, one day they're caught secretly meeting in the changing room and photographed by students. Using the photos as blackmail, the students force the two women into brutal group deepthroat sessions. Teacher Tsubaki is raped by the students, while Teacher Yuzuha, seeking help from a male teacher, is instead betrayed and sexually assaulted by him. The two female educators are ultimately reduced to sex slaves and cumdumps at the mercy of the male staff.
