CMC-209 Tsukino Yuria: Wife Slave and Humiliation Academy SM CineMagic

A young teacher at a certain academy is married to a kind wife. However, the wife, Yuria, harbors a deep-seated masochistic desire, becoming aroused by being forcibly dominated by her older brother figure—her teacher. She is later captured by the depraved headmaster and thrust from marital bliss into a world of torment. Unable to suppress her submissive urges, she willingly volunteers as a hardcore discipline subject. Bondage, domination, humiliation, and every manner of torment are used to break the beautiful wife's spirit. Driven by twisted logic and overwhelming desire, she is intoxicated by the highest levels of pleasure and pain.
