The nerd, now rock hard, pleads for more. She smiles, pushing him onto the bed, and spreads his cheeks, revealing his virgin hole. She spits on it, rubbing her thumb around the rim, making him squirm. Grabbing a bottle of lube, she slicks up her cock, pressing the head against his tight entrance. He winces as she pushes in, but she shushes him, promising pleasure. She begins to thrust, slowly at first, then faster, her tits bouncing in time with her hips. He grabs his cock, stroking it in time with her movements, moaning loudly as she pounds his ass, leaving him a panting, cum-covered mess.
