"I don't mind the thrill of sex," says Nao Mizuki, a lewd woman with a soaking wet pussy, who stirs up shame through reverse exposure. She binds the voice of a normally sensitive M-man who can't help but scream, and leads him to pleasure by playing with his sensitive body in a store, office, or a parking lot where people are passing by, making him a captive of the pleasure of "holding back his voice." This is a four-part series of completely ad-libbed, guerrilla-filmed, slutty live performances that stimulate the erogenous zones and give a thrill to the body, as well as the mental pleasure of being violated.
