A model-bodied mature woman, “Reiko” (小早川怜子), visits a man's home. Her part-time job is simply to take care of the man's sexual needs. The man humiliates her as if unleashing his lust, but 小早川怜子 grimaces while dripping her fluids and moans lewdly. With masochistic tendencies, she doesn't do it for the money — what she truly desires is to be masochistically trained by the man.
