The Woman From SECReT - Part Six - Sara St. Clair

After her previous defeat, Sara St. Clair has assumed her alter ego as Dynamic Damsel for a rematch with the clones. One of them exposes the super-lady to Upsilon radiation, thinking it would rob her of her unparalleled strength. But his error is costly and she quickly takes care of him. A second clone gets the upper hand with a paralyzing spray, and Dynamic Damsel falls into his clutches and she's unmasked. He uses a sinister device to alter her molecular structure and destroy her superhuman strength. The vanquished damsel is ballgagged and tied up with a powerful vibrator roped in place. Once it's turned on, the defeated champion of justice surrenders to the irresistible device and submits to a helpless orgasm.
