Diann Miller, the busty, big-assed MILF, can't resist the temptation of her stepson's big cock. She sneaks into his room, finding him asleep, and begins to stroke his shaft until he's rock hard. She climbs onto him, guiding his thick, straight cock into her wet, hungry pussy. She bounces on him, her big natural tits jiggling, as she fucks him missionary style, then flips around for a doggystyle pounding, her big ass slapping against his thighs as she takes every inch of him.
