Lucky, the slender Ebony, is the unwitting star of Dr. Sparky's latest electrical experiment. Stripped bare and tied down, her body is a canvas of possibilities for the good doctor. He starts with a gentle, teasing touch of the violet wand, the spark dancing across her ebony skin like lightning on a stormy night. Lucky's body responds, her nipples hardening, her pussy growing wet. Dr. Sparky watches, a scientist examining his subject, as he increases the intensity. Lucky's cries fill the room, but her body tells a different story. She's arching, writhing, her hips bucking as the current courses through her, pushing her towards a climax unlike any other.
