As the house falls silent, David, the lanky stepbrother, can't help but notice AlkaModel's curvy form swaying to unheard music in her room. His eyes linger on her hairy armpits, a sight that sends a thrill down his spine. He knocks, entering as she turns, clad in a skimpy top and shorts. She's practicing her seductive dance moves, unaware of his growing bulge. When she catches him, she blushes but doesn't stop, her hips moving in a sultry rhythm. He steps closer, drawn to her like a moth to a flame. Their bodies press together, her ass rubbing against his hardening cock. She moans softly, her breath hitching as she feels his thickness. Their hands explore, their bodies entwining in a forbidden dance that's far from over.
