Luke, nervous yet excited, positions himself behind his busty stepmom. Her big tits hang heavily as she braces herself, looking back at him with hungry eyes. His throbbing cock presses against her virgin asshole, and she gasps, "Push it in, baby. I want you to fuck me so hard, I can't walk straight." He obliges, slowly inching his way into her tight, resisting hole. She moans, her pussy dripping with excitement as he begins to thrust, her anal walls gripping him tightly. The sound of their flesh slapping fills the room, echoing their forbidden pleasure.
