The best part of being the school nurse is having the infirmary all to herself, where no one can interrupt her secret hobby. She does not truly want to be caught—the humiliation would be unbearable—so she thrills herself by exposing her body right on the edge of discovery. Visitors come by every day, and being exposed could cost her job, but she cannot stop even though she feels guilty toward the adult students in this role-play. Her small act of stress relief spreads beyond the infirmary and eventually triggers an incident involving the entire school.
