As the carnival's energy courses through Rio's streets, a husband's curiosity piqued by his wife's sudden interest in traditional dance classes, leads him to discover her true, carnal lessons. Hidden in the shadows of their bedroom, he spies on her as she enthusiastically pleasures her dance instructor, her moans mixing with the distant music, her body glistening with sweat and desire. The husband, a willing participant in this cuckold's tale, strokes himself to the sight of his wife's unabashed, exotic lovemaking, her cries for more echoing in his mind like the city's lively carnival chants.
