He enjoys the sight of her cute face on his chest for a few moments, grabbing her asscheeks tight in his hand while the other continues to stroke and clutch her scalp.  Wiggling now from the feel of her tongue and lips on his nipples, he removes the hand from her ass reluctantly, and undoes his pants fumblingly, pushing them down enough to pull his cock out from under the fabric.  He grabs up the girl's big dick in his hand, gripping his shaft as well, and starts to jerk the both of them off, rubbing their dicks together.
