"You're not supposed to do this," the boyfriend murmurs, his eyes locked onto his girlfriend's every move. She just smiles, her fingers tracing the neckline of her top, slowly pulling it down to expose more of her breasts. Her hips sway seductively, her body pressing against his growing bulge. She leans in, her breath hot on his ear, "But you like it, don't you?" Her hands roam over his chest, her nails gently scratching, before she turns around, her back arching as she grinds against him, her skirt riding up higher, revealing the damp spot on her panties. The room fills with the sound of their heavy breathing and the soft music, the air electric with their building desire.
