A sexy brunette is used as the subject of a sex experiment by two horny lesbian researchers. First she is tied arms over head with her big tits lashed down as she is probed with a mechanical fucking device. She is recorded while she cums over and over, straining in her bonds. Then she tightly frog tied and gagged while her sore nipples are clothes pinned. Helpless, she moans as a researcher helps herself to her wet hairy snatch.
