On a business trip, a doctor pulls a mysterious device from his bag... As eerie vibrations begin, a woman's body trembles, emitting sweet, lewd screams that echo through the room. Is this treatment—or something else entirely? Captivated by the device's unique pulsations, the women gradually surrender themselves to the doctor. Tormented at their most intimate areas, they gasp and moan in apparent distress, yet repeatedly succumb to waves of release, endlessly immersed in overwhelming pleasure.
