Michelle's brother, engrossed in his solo session, doesn't notice her watching until he feels her eyes on him. She's mesmerized by his cock, his hands, the way he grinds his hips. He asks if she likes what she sees, and she nods, confessing her desire to see him cum. He obliges, his strokes getting faster, his breath heavier, until he explodes, his cum shooting onto his stomach, Michelle's hand still in her panties, her fingers coated in her arousal.
