"It seems the teacher needs a thorough punishment, doesn't she?" Miyu Kanade, a refined and elegant young lady, invites female students to her "Punishment Club" where she conducts sophisticated yet intense female domination sessions. Miki Sunohara, a female teacher who accidentally witnesses one of these sessions, soon becomes the target of Miyu's sadistic desires. Bound tightly with rope, whipped, toy-played, subjected to humiliating lessons, clamped with clothespins, forced into deep-throat penetration with a penis vibrator, and made to clean her own pussy after urinating—Miki is gradually broken down, dripping with arousal as she succumbs to complete control. A world of lesbian domination unfolds, elegant yet intoxicatingly perverse.
