The stepbrother's disbelief turns to pleasure as his stepmom, a curvaceous MILF, mounts him, her forbidden cunt sliding down his throbbing cock. "You're so big, baby," she pants, her tits swaying as she rides him. He grips her hips, thrusting up, their bodies slapping together. Cum4k drips from her pussy, coating his balls as she grinds, her orgasm building. "Fuck me, you little bastard," she growls, their taboo lust consuming them.
