Sachiko was a female teacher and at the same time a student's sex slave. The student was informed of an affair with a colleague's teacher, and he was required to have a physical body in exchange for not revealing the facts. Sachiko, who cannot lose her teaching profession, had no choice but to succumb to the threat. Student demands gradually escalate. In the school toilet. In the classroom. A physical service order is given in a situation where other students are nearby. If you refuse, everything is over. Even if you say aloud, everything is over. Sachiko had no choice but to endure while trembling with shame.
