Her heart races as she mounts him, his thick cock pressing against her entrance. Slowly, she takes him in, gasping at his size. Bouncing up and down, she rides him, her tits bouncing in rhythm. He grips her hips, guiding her, his cock throbbing inside her. As he's about to cum, he pulls her down, filling her with his load. She keeps riding, feeling his hot cum inside her, marking her as his.
