The stepson's mother, a busty mature woman with a big, round ass, is none the wiser as he spies on her in the shower. Her body glistens, and her moans echo, igniting his lust. He enters the bathroom, his cock hard and ready. She's startled but intrigued by his erection. He moves closer, and she reaches out, touching his cock tentatively. Their gazes lock, and she turns, presenting her big ass to him. He lubes up, his fingers sliding into her tight asshole. She moans, pushing back against him. He replaces his fingers with his cock, fucking her slowly, then harder as she begs for more. He pounds her ass, his balls slapping against her pussy, until he can't hold back any longer. He pulls out, coating her ass and pussy with his hot, creamy load.
