Misa Kudo, a 29-year-old English teacher. Boasting an outstanding figure with G-cup breasts and a 90cm wide ass, she is wildly popular among her students. However, targeted because of her popularity, she becomes entangled in an extremely sinister plot orchestrated by school staff to train her as a sex slave. Bound and confined outdoors with a mouth gag, her entire body painted with lipstick, she is forced into deep-throat climax training, made to cum repeatedly until cummy fluids drip from her mouth. Ultimately awakening as a masochist, Misa drools and leaks arousal fluid simultaneously, embracing her role as a human toilet in a lewd, depraved state. Her appearance becomes a symbol of perfectly controlled pleasure, captivating all who witness it.
