Lady Naomi does not like to tolerate any nonsense when it comes to the pace at which she wants things to be done. That is why she chose to use her feet to dominate this guy because he was slow at finishing the work she had given her. She did not have a lot of time so he had to be forced to do things faster. As he got trampled and was made to lick her feet, he found extra strength and he did the work faster.
Lady Naomi wanted to flaunt her sexy feet as she had not done it in ages. So she did what she does best and she wore lingerie and stockings. Then she teased this guy for fun and the guy thought his prayers were answered but he was shocked to learn that they were not and he was just being teased and denied. He ran home to jerk off when she did not give in to his request for fucking.
