In a cramped Brazilian apartment, siblings Max and Carla can't resist their forbidden desires. Max, caught masturbating, confesses his fantasies about Carla's tight pussy. She, equally aroused, agrees to explore their taboo cravings. They sneak touches and tastes, Max's thick cock hard against Carla's ass as she leans over. Their moans fill the tiny space, but they're interrupted by their mother's knock. Panting, they hide, hearts pounding, eager for their next stolen moment.
