A curious sister, driven by horniness, sneaks into her brother's room, drawn to the bulge in his pants. She finds him sleeping, his cock tenting the covers. Unable to resist, she gently strokes it, awakening him. He looks up at her, surprise and lust warring in his eyes as she exposes her big, luscious tits. She tentatively fingers her wet pussy, her inhibitions melting away, as she leans down to take his cock in her mouth.
