While Dad busies himself in the kitchen, my step sister's desires consume her. She corners me, her eyes wild with lust. "I need you inside me," she pants, pushing me down on the couch. She straddles me, her wet pussy grinding on my hard cock. I grab her ass, pulling her closer, as she rides me, her moans muffled by my shoulder. We fuck hard, her pussy clenching around me, until I fill her with my cum, our bodies slick with sweat and satisfaction.
