Michelle's dark skin glistens with sweat as she rubs herself against the cool tile of the shower, her mind a whirlwind of forbidden lust. Her fingers tease her swollen clit, then plunge into her tight, hungry cunt. She gasps, her body tensing as she nears orgasm, when the bathroom door swings open. Her brother stands there, his eyes widening at the sight of his sister's naked, writhing body. Michelle freezes, her breath hitching, her heart pounding. The air is thick with tension, the scent of her arousal filling the room.
