Because of my own mistake, I'm being blackmailed by a student. To protect my position as a teacher, I had no choice but to obey the student's demands—forced to offer my body day after day. On Saturdays in the music room, the music teacher torments me repeatedly, dragging me into vulgar acts. Each time, I climax over and over, my body increasingly drawn into those pleasures. I can't let go anymore, I can't stop.
