Every day, the female teacher falls victim to unexpected molestation, gradually losing all resistance as she becomes physically and mentally overwhelmed by the assailant's expert techniques. Her first attack occurs during her morning commute on a crowded train, where she's then lured into a hotel under the guise of being comforted, leading to a second assault. After arriving late to school, she receives disciplinary punishment from the vice principal in the infirmary. Later, on her way home, she's targeted again by the molester, fleeing back to her apartment without panties. As these incidents repeat daily, she continues going to work torn between pleasure and anxiety.
