KAYAMA NATSUKO plays a kinky, masturbation-loving madam fascinated by losing control. Invited to visit an unusual mansion, she discovers rooms run by brainwashing fetishists. As the men manipulate her mind and push her through increasingly obscene acts, pleasure overwhelms her and unleashes her buried desires. She sobs, convulses and reaches repeated mind-blowing orgasms until she is left dazed, willingly performing sexual acts for the group and completely surrendering to their training.
