Elite pain: Mathematical experiment in natural pleasure

A mysterious woman, bound and gagged, is subjected to a series of intense, erotic experiments. Her body is marked with intricate symbols, and she's left vulnerable to the whims of her unseen tormentor. A whip cracks, and she screams in pleasure-pain as it lashes her large, natural breasts. Her cries echo through the sterile laboratory as she's hit and pleasured, her body writhing in response to each strike.
