Bored and alone, a brother retreats to his room, his mind filled with taboo thoughts. He strokes his hard cock, the pre-cum dripping from his tip. His imagination runs wild with images of his sister, her body naked and willing. He fantasizes about fucking her, his thick cock stretching her tight pussy. The room fills with his grunts and the sound of his hand sliding up and down his shaft. He edges himself, the pleasure building, before finally exploding, his hot cum shooting onto his stomach.
