In the dimly lit hallway, the scent of forbidden lust hangs heavy. A creaking floorboard betrays Michelle's stealthy approach to her stepbrother's room. She finds him sprawled on his bed, his thick cock tenting his boxers. His eyes flicker open, meeting hers, and without a word, she climbs onto the bed, straddling him. Their hearts pound in sync as she grinds against him, her wet panties offering no barrier to his growing erection. Their lips meet in a hungry, desperate kiss, tongues dancing as they explore each other's mouths. Michelle's hands roam, tracing the lines of his abs, his pecs, before finding their way to his cock, stroking it through the thin fabric. He groans, hips bucking slightly, and she smiles, biting her lip as she slips her hand inside, wrapping her fingers around his bare flesh.
