In the dim light of the bathroom, a brother and sister stand, both naked and vulnerable. She's been touching herself, her pussy wet and aching, her body craving release. He's caught her in the act, his eyes wide with surprise and something more. They argue, the tension between them thick with unspoken desire. Later, they apologize, their naked bodies still pressed together. She looks down, her eyes widening at the sight of his cock, thick and long, standing at attention. He sees her looking and swallows hard, his body aching for her touch. They stand there, their breaths coming in short gasps, their bodies yearning for each other. They know they shouldn't, but the pull is too strong, the desire too great.
