Sibling Sins in Shadows

The creaking floorboard announces his presence, as he steps into her room, uninvited. Her back is to him, her lithe form silhouetted against the moonlit window. She's dancing, lost in her own world, unaware of the effect she has on him. He watches, his heart pounding, his cock twitching, as she spins, her nightgown clinging to her curves. She sees him, freezes, then smiles, a wicked curve of her lips that speaks volumes. She turns away, letting the gown slip off her shoulders, revealing her naked form. He swallows hard, his eyes locked on her ass, as she walks towards him, hips swaying, a predator's gleam in her eyes.
