Bed creaks under their weight. Stepmom's round ass cheeks part wide while stepson works his fingers into her asshole, lubing up for the main event. She moans loud, hips bucking back against his hand. Flips her over missionary-style, cock pressing at her hole — finally gives in, inch by throbbing inch disappearing inside. Her legs wrap around him tight. He thrusts steady, building speed until she's clawing the sheets, tits bouncing wild. Sweat slicks their skin on that pink bedspread. Pulls out for a messy cumshot across her cheeks — she grins, spent but satisfied.
