Knowing that her husband was drunk helped lady Zora get the courage to humiliate him. She knew he would not remember much when he got sober so she made him lick her stinky feet after teasing him that if he licked her feet she would get turned on and he would fuck her like he had been meaning to. And he took the bait. Being drunk meant that he did not immediately tell that her feet were smelly and she laughed as he went on.
