Shyla instinctively kissed up and down her naked body

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.
