In the dimly lit room, a brother's gaze wanders, his thoughts consumed by his sister's every move. He's seen her, all of her, in moments she thought were private. His mind races, imaging her soft skin, her delicate curves, her breathy moans. His hand finds its way to his throbbing cock, stroking it gently, wishing it was her touch. Yet, he keeps his secret, knowing the line he's crossing, the taboo he's indulging in. Every stolen moment, every hidden touch, every fantasy, he keeps it all locked away, his sexy little secret.
