"Teach me how to suck cock, cuz," she pants, straddling him on the couch. He obliges, guiding her hand to stroke his stiff cock. She learns fast, her wet lips wrapping around him, taking him deep. He groans, grabbing her hair, thrusting into her mouth. "Fuck my face, cuz," she moans, taking every inch. Soon, he's fucking her tight pussy, their bodies slick with sweat, their moans filling the room as they give in to their incestuous desires.
