Since puberty, Kohaku has harbored deep romantic feelings for her uncle. Worried about her emotional state, her mother pushes her into arranged meetings early, pressuring her to secure an engagement while still in college. Reluctantly, Kohaku chooses a fiancé who is the complete opposite of her mother's ideal— a young man with distinct sadistic tendencies. This decision draws her into a world of masochistic pleasure orchestrated by both her uncle and her fiancé. Spanking, electric vibrators, anal inspections, enemas and forced defecation, nipple torment, pussy bondage, deep-throat gagging, anal fellatio, nose hooks, full-body wax play, gagged flogging with a nine-tail whip— a cascade of intense BDSM elements converge to shatter her body and mind in a shocking, transformative experience.
