When Charlie Dean shows up at Sybil's dorm room and interrupts her workout, he finds her eager to try some raunchier exercises. As they start to fuck, things aren't nearly as spicy in the room next door, where studious Stacy Cruz is spending a typically rigid and quiet evening hitting the books. When Stacy Cruz hears what's going on next door, though, she decides to masturbate. But as she starts fingering herself, Sybil gets fucked so hard from behind that she breaks through the adjoining wall - with her face landing right over Stacy Cruz's pussy. Intrigued, Sybil takes over while continuing to get fucked, with things taking a wilder turn when Charlie Dean catches on.
