In the dimly lit room, Casal Alegre's esposa gostosa writhes in pleasure, her moans filling the air as she and her husband indulge in their 'de-quatro' fantasy. Her hips move in rhythm with his, their bodies slick with sweat as they lose themselves in the moment. The room is filled with the scent of their desire, a heady mix of perfume and sex, as they push each other to the brink of ecstasy and beyond.
