In this adult teacher-and-student role-play, Kanna is their homeroom and disciplinary teacher, always sternly declaring, “Rules are absolute. They exist to be obeyed.” She treats the diligent class representative more kindly than everyone else, and he treasures the feeling of being special to her. He never imagines that the respectable Kanna is secretly obsessed with obscene thrills. One day after school, he catches her wandering around campus with no panties on, exposing herself wherever she can. When Kanna realizes he has seen her, she invites him to join her indecent games.
