I'll let you hold my homeroom, so please let your teacher go.

A classroom after school. On the blackboard, it is written as "special supplement". Apparently he's repairing the rest. The boys are Yokoyama and Ota. Then, two beautiful teachers, Kisato Ishiguro and Ami Kikugawa. Then, Kikugawa and Ishiguro teach each student to look at them individually. He teaches his students kindly and erotically. Two male students who try hard to "remain in school after school"。 There are two beautiful female teachers who smile and look at the situation. It is a forbidden, school-wide swap teacher who replaces each other's homeroom and revolves around it.
