The house echoes with her lustful cries as she fingers herself, her big ass grinding against the sofa. Her stepson, drawn by her moans, enters, his thick cock straining against his jeans. She freezes, then beckons him, her pussy juices glistening. He slams into her, fucking her roughly, their bodies slapping together. She claws at his back, her orgasm ripping through her, her pussy clenching around his cock as he empties himself inside her, their bodies slick with sweat and spent fluids.
