Big-titted Angela White visits the plastic surgeon Dr. Carter Cruise for a breast reduction consultation. Her enormous natural boobs interfere with her life. Aside from the unwanted attention, she has trouble fitting into clothes and playing sports, and her back always hurts. At the doctor's request, she takes off her shirt and bra, releasing her tits for inspection. During a surgical consultation, plastic surgeon Dr. Blair Williams is marking up Gia Paige's body for liposuction. Blair recommends injecting the fat from her tummy into her ass for a Brazilian butt augmentation. Always looking to upsell her services, Blair also recommends a boob job to give Gia’s breasts a womanlier appearance. Shyla jennings scrolls through the job listings and answers an ad for a research study on the physiological effects of exposure to lesbian pornography. It sounds weird but a lot better than the other options. Shyla goes down to the lab to meet the doctor Serena Blair and her research assistant Melissa Moore. They sit her at a desk in front of the lesbian porn while they set up the biofeedback to record the data. They instruct Shyla to remove her panties and they apply an electrode to her clitoris. Although reluctant, she returns to watching lesbian porn, becoming more and more seduced, forgetting it was all a test to begin with!
