In a cramped Brazilian apartment, a horny wife, a "puta" and "safada," seduces her husband's "amigo," a "fixo" in their group. She's a "comedor," hungry for cock, and her husband, a "corno," watches, stroking himself. They fuck her together, the husband's friend taking her roughly from behind while the husband watches, jerking off before joining in, filling her with both their loads.
