Kit Mercer, the insatiable MILF, can't resist her stepson's thick cock, even as he chitchats on the phone. She sneaks up, her big tits heaving, and takes his big dick in her mouth, sucking him off in POV while he's oblivious. Once he notices, she climbs on top, riding him in cowgirl, her tight pussy milking him. The taboo excitement builds as she moans, her orgasm imminent, until he explodes inside her.
