As the final chapter of this fantasy opens, Dr. Gil Horable is continuing his unexpected late-night visit to his ex, Karen (Sage Pillar). The stunning blonde is securely bound to a chair with her legs tied wide apart, and there's a vibrator fixed in place between her thighs. Our busty damsel hasn't been thrilled with the devices the evil scientist has subjected her to so far, and this last one is no exception. She recognizes it from one from their earlier marital experiments. She groans and complains that she's always too sore after a six hour orgasm. But the perverted researcher isn't paying any regard to her protests. He stuffs a foam ball into her mouth and tightly winds med-wrap around her head to keep it in place. The wicked doctor then switches on the device and prepares for a long and satisfying show of Karen's comeuppance. The booted babe makes a token effort to evade the inevitable combination of effects from her ex's insidious invention and the irresistible song of the Hitachi. But her resistance isn't up to the challenge, and it's not long until the bound and gagged beauty is overcome by what she knows will be a long series of helpless orgasms. Several hours later we find that her arousal has outlasted the vibrator! Then when Dr. Horable checks on the lovely target of his revenge their story has a final twist!
