In a normal school life, everyone has had to use the nurse's office at least once. When a schoolgirl falls ill and is weak, the nurse who should be kind is waiting for her. However, the nurse at that school is a molester who plays with the students she targets. The schoolgirl is made to climax over and over again so that the other students who are absent don't notice. Gradually, she becomes obedient to the nurse and begins to seek the pleasure herself.
