Brazilian amateurs 'Marido' and 'Esposa' spice up their marriage with a daring game of cuckoldry. 'Esposa', a 'puta' with a 'casada' innocence, seduces her husband with the tantalizing question, 'Quer ser meu corno?' The camera captures their intimate moments, as 'Esposa', a 'novinha' in this game, takes control, whispering 'Então vai ser!' - 'Then, it's gonna happen!' - sealing their descent into a world of cuckold fantasies.
