The girls exchange a guilty glance, their faces flushed with excitement and shame. They continue, their bodies trembling as they give in to their taboo desires, Melanie's sister straddling her brother, impaling herself on his rigid member while Melanie watches, her own pussy aching with jealousy and arousal. The room fills with their cries of pleasure, their bodies slick with sweat and cum, as they chase their climax, oblivious to the world outside.
