Under the guise of treatment, the sadistic female doctor plays with two patients as human toys. The doctor fixes the patients' balls with a humbler, then attaches low-frequency therapy pads to the balls and turns it on. Next, the doctor places clothespins between the balls and ties them with string, then pulls the string to remove the clothespins.The doctor also drips candle wax on the patients' butts and balls, then knocks the wax off with a riding crop or whip. Every day, under the guise of treatment, the female doctor uses her patients like tools to indulge her sadistic sexual tendencies.
