Our secret trysts in her bedroom become wilder each time. Today, she's on all fours, ass up, begging for my big cock in her ass. I tease her with my tongue, then slowly push in, feeling her tightness stretch around me. I grab her hips and start fucking her, hard and deep. She moans and pushes back, taking every inch. I can feel her climax building, and as she screams my name, I pull out and cum all over her ass.
