Suddenly attacked by several students and finger-fucked to orgasm, new teacher Yuria investigates the truth behind the incident but is instead forcefully made to have her face rubbed with a penis by her advisor, the PE teacher. She cries halfway through being raped. The teacher pulling strings from behind uses a dildo to make her climax six times in a row and urinate involuntarily. Losing her sanity, she actively seeks sex. In the end, she gives naked lessons, taking students' penises into her mouth.
