Alex Coal, the naughty med student, can't help but fantasize about her step-uncle, Quinton James, during her online lectures. She imagines his strong hands exploring her body, his thick cock replacing her vibrator. When Quinton walks in on her masturbating, he decides to play along, examining her 'ailments' with his tongue and fingers before she returns the favor, taking his massive cock deep into her throat. Their taboo encounter escalates, with Alex riding Quinton's cock reverse-cowgirl, her big tits bouncing, until they both climax in a mess of sweat and cum.
