Trapped in a cramped closet, a brother's lust rages as he watches his sister undress, her curves on full display. He can't help but imagine her tight pussy, her soft lips, her round ass. His cock throbs in his pants, begging for release. He unzips, his hand wrapping around his thick shaft, stroking slowly. His sister, lost in her own world, doesn't notice his lewd gaze, her body swaying sensuously. The brother's breath comes in ragged gasps, his lust growing with each stroke. He knows he should stop, but the sight of her is intoxicating. He strokes faster, his grip tightening, his body tensing as he nears his climax. Just as he's about to come, his sister turns, her eyes meeting his, shock and betrayal etched on her face.
