A female masochist is trained using the world's most powerful vibrator fitted with an extra-thick attachment. A remote-controlled vibrator is inserted into special indented panties, including scenes of masturbation. A woman wearing a red PVC bodysuit has a finger-type attachment mounted on the vibrator for a training session. Later, the attachment is switched to an extra-thick type, and the woman's arms are restrained to a window as the intense vibrator stimulation continues. The scene culminates in a massive squirting climax.
