Riko Mizusawa, a married woman possessed by foreign blood, suddenly becomes wildly lustful, satisfying her desires with vulgar, insatiable sexual acts. When her husband's senior visits, she knocks him unconscious and devours his cock with face-sitting 69, repeatedly forcing him to ejaculate. To restore her former self, her husband entrusts her to men who know the weakness of the cursed blood. She undergoes sacred water sex, intense toy torture with vibrators and dildos, deep-throat penetration, and scalding hot candle wax poured over her body, her screams echoing throughout. Yet the evil spirit cannot be expelled—until her husband finally purifies her with fierce piston-like intercourse, flooding her with hot cum and driving her to ultimate climax.
