In their dimly lit bedroom, Marido Passivo's eyes widen as his wife reveals her secret, a strap-on dildo glistening with lube. She guides him onto his hands and knees, her touch firm yet gentle. She teases his asshole with her fingers, making him squirm before slipping the dildo inside. She starts slowly, allowing him to adjust to the unfamiliar sensation, then picks up speed, her hips slapping against his ass. He moans louder, his body tensing as she pegs him deeper, harder, their bodies slapping together in a symphony of carnal desire.
