Shyla Jennings needs a job so she can afford some new clothes. She 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. She allows it, reluctantly, then returns to watching porn. She's impressed with the quality on Girlsway.
The researchers comment on the spike in the numbers, but Shyla swears she's straight. She even has a boyfriend. They assess her as a potential lesbian outlier. When the numbers continue to climb, Serena asks the subject to calm down, as she could be skewing the meters. Shyla wants to know if that means she's a lesbian. They can't answer her, but her data is in line other lesbians in the study.
Shyla begins freaking out, believing this means she's a lesbian. The researchers are baffled. Indeed, Shyla's data is off the charts. In her heightened state of excitement, Shyla wants to know if Serena and Melissa are lesbians, if they think she's cute, and if would they make out with her. They won't answer her question, but Serena decides to test the subject's reaction to external stimulus. She instructs her assistant Melissa to expose her magnificent tits, which Shyla immediately puts in her mouth. Serena asks Melissa to remove the rest of her clothes, noting how Shyla instinctively kisses up and down her naked body.
Shyla turns to Serena and undresses her. For the sake of the study, Serena allows it. The hot participant messes with the researchers and an explicit lesbian threeway ensues. When Shyla licks melissa's pussy, they can't believe it's her first time. Melissa eats out Shyla's pussy, in the interest of science, then Serena takes a turn. They tag team Shyla's clit till she cums. Serena plants her dripping wet pussy on top of Shyla's and Melissa licks her asshole till she explodes. The researchers switch up positions, and Serena rims Melissa while she laps up Shyla's pussy juices. Then Shyla tribbs Serena and cums really hard, feeling much better about her diagnosis!
