Wet slurps echo off bedroom walls. Stepsister kneels, brown hair falling over bare shoulders, mouth stuffed with stepbrother's thick cock. Fingers grip shaft, cheeks hollow as she sucks hard. Sheets rumple under knees. Cut to her flat on back, legs splayed, tits heaving with each breath. Hands pin thighs apart. Cock plunges into shaved pussy, skin slapping loud. Ass lifts off mattress. She grips his arms, nails digging in. Pace builds relentless, bed frame rattling. Juices drip down crack. Final thrusts bury balls-deep, her moans turning sharp.
