You hold her ass cheeks apart, your cock standing tall against her pink, puckered hole. "Fuck my ass, baby," she pleads, biting her lip. "Do it hard." And you do. You slam into her, driving your cock deep into her tight, warm flesh. She screams and gasps, her body arching beneath you. You grab her hair and pull her head back, forcing her to look at you as you fuck her. Her breathing becomes ragged, her eyes wild with lust and pain. Your hips snap with each thrust, slapping her ass in a rhythm that sends shivers down your spine. You can feel her insides clenching around you, her internal muscles gripping your cock like a vice. Your stomach ache is slowly fading away, replaced by the raw power of your primal desire.
