The counselor guides housewives troubled by frigidity and sexless marriages toward cervical orgasm therapy. Female patients suffering from issues like the inability to reach climax are gradually broken down through treatment with intense pleasure and consecutive orgasms. With the cunning suggestion, "Now let's practice and stimulate with a male organ," the counselor proceeds to have sex with the sexless housewives. In vol.04, a new patient is drawn into the vortex of treatment by his hands, which specialize in female sexuality.
