The one who reigns at the top of the school caste is a slut...The next target is a beautiful female teacher from the lowest caste. - Tsumugi, a serious female teacher, is exploited by a cheeky student and becomes the prey of a slut who licks her body as much as she wants! - Her pride as a teacher is crushed by the whispering of obscene words, the intertwined tongue of a slut, and the persistent double torture, and she turns into a bitch who obediently clings to the pleasure that attacks her! - Lesbian education where the position is reversed and the public morals are disturbed, where the school exposes lewdness and climaxes repeatedly.
