Waves crashing against the sandy beach, the blonde pins her stepbrother down and slides onto his stiff cock with urgent rhythm. Her curvy hips grind deep while she glances back at her sleeping husband, tension building with every bounce. Tits heaving under her top, she leans forward, pussy clenching as he thrusts up from below. Stepbrother grips her ass firmly during the risky ride, both stifling moans amid the ocean roar. She cums hard, soaking him before he unloads inside her quivering hole.
