A husband photographs his wife in bondage, and her obscene beauty excites them both more than ever. Though hesitant, she agrees to fulfill his fantasy of filming her while a professional rope artist ties her up. Their arousal is still burning when they return home, making the sex especially intense. Later, unable to contain her desire, she binds herself and masturbates in the kitchen at midnight. She then secretly visits the rope artist alone and asks him to bind and train her behind her husband's back.
