My sister's best friend is over, and I can't stop thinking about his thick cock. I've caught him staring at my big ass and big tits before, and I know he wants me. I decide to tease him, putting on a show as I masturbate in the bathroom, my moans echoing through the house. He can't resist the temptation, sneaking in to watch me finger my wet pussy. I put on a show for him, rubbing my big boobs, and he loses control, pulling out his hard cock to stroke it while he watches me play with myself.
