"Casal Paraíso" presents a torrid tale of married lust, as a voluptuous Brazilian wife, hungry for more than her husband's love, indulges her carnal desires. With her husband away, she invites a mysterious lover to their home, eager to satisfy her insatiable appetite. The passionate interloper arrives, and the wife, a 'gostosa' (hot one), lives up to her name. She's a 'puta' (slut) in the best sense, reveling in her husband's absence to explore her deepest, darkest fantasies.
