Female teacher Emi Fukatsu is tearfully begged by bullied student Shionomiya and reluctantly forced to have nude photos taken. These photos fall into the hands of delinquent students, who begin threatening Emi and eventually subject her to outright coercion. Despite fierce resistance, she is gradually overwhelmed as they take complete control of her body and mind. During class, after school—every moment of her life is under their watchful eyes and grasping hands. Ultimately, she is entirely dominated by them, falling into the role of a helpless sex slave.
