Adult college-student role-play: Nana loves her boyfriend but is frustrated that he never gives her foreplay. A smooth-talking professor obsessed with licking finds her diary describing their sex life and uses what he learns to target her during a seminar retreat. He licks every inch of her body and plots to steal her away, even making her crave his humiliating cunnilingus in front of her boyfriend during a video call. Overwhelmed by pleasure, she is ultimately reduced to a compliant creampie plaything.
