At the top of the school caste system is a slut... this time the target is a beautiful female teacher at the bottom of the caste system. The serious female teacher Tsumugi has her weakness exposed by a cheeky student, and she becomes the slut's prey as she is licked and violated as much as she wants! Her pride as a teacher is crushed by the whispered obscene dirty talk, the slut's tongue that entangles her, and the sticky, relentless double attack, and she is reduced to a bitch that obediently clings to the pleasure that attacks her! She exposes her lewd behavior all over the school and climaxes repeatedly, disrupting discipline in this role-reversal lesbian education.
