As the house sleeps, step-siblings explore forbidden desires under the cloak of darkness. Michelle, her heart pounding, slides into her stepbrother's room. He's already hard, his cock tenting the sheets. She climbs onto the bed, straddling him, her nightie barely covering her. He grips her hips, guiding her down onto his thick shaft. They move together, their bodies slick with sweat, the only sounds their ragged breaths and the creaking bedsprings. Outside, the moon watches their taboo dance.
