In this adult school role-play, discipline teacher Nami is feared for sternly insisting that every rule must be obeyed. She is kind only to the diligent adult class representative, who quietly develops feelings for her. Then one day after class, he catches the supposedly respectable teacher roaming the school without panties and indulging her exhibitionist side. When Nami realizes he has seen her, she invites him to join her filthy game.
