A vicious obscene act is repeated at a certain treatment center. The married women, dressed in paper panties and paper bras, lie on the bed and surrender themselves to the therapist. After loosening the lymph nodes throughout the body and improving blood circulation, the therapist will massage the area around the genitals. He will massage the stomach, which is said to be a surprisingly sensitive area, and give a special massage using secret oil to the classic groin line. In the massage from the base of the legs to the area around the vagina, he pretends that his hand has slipped and touches the labia majora and clitoris, making the female customer wriggle her hips. The female customer, who has become in a lewd mood, will feel it to the core and climax.
