She is the Madonna of the school, with a great reputation as a teacher. A perverted teacher who indulges in an affair with a student. Kaho lives her life as a teacher while switching between these two faces. However, when a student starts asking for a relationship even at school, the balance is upset. It's a dangerous act that could end her teaching career if she is seen. Kaho refuses, but her words don't reach the student whose desires are out of control... At the very least, she tries not to make a sound. In a corner of the school building, Kaho silently accepts her student's penis.
