In the vibrant streets of Rio, a married woman, a 'casada', finds herself craving a 'cuzinho', a tight young cock. She's a 'carioca', a native of Rio, and her sexual appetite is as fiery as the city's sun. With her husband away, she seeks out a young 'gato', a handsome stud, to satisfy her 'safada' desires. The 'corno' husband might be home soon, but she doesn't care, she needs that 'metedor' to fill her up, to make her scream with pleasure in their bustling, steamy city.
