Kinbaku

Waking up on a stage, Sayaka and Tsuda find themselves confined by evil mastermind Ando working wth Sayaka's husband, Yamazaki. Disovering the adultery of his young wife and his secretary, Yamazaki asks Ando to use Kinbaku (bondage) as punishment for his wife's betrayal -- but Sayaka's reaction gradually changes by Ando's skilled and erotic bondage technique.
