Lady Shay loves to try new ways of punishing people. This guy was disrespectful and the mistress could not take it. She had to punish him and she did it with her cuckold fetish. He was turned into a cuck and had to watch her have fun with another man while he wanted to do the same with him but he was disrespectful and could not do that with her.
Lady Shay was getting a lot of attention from her ex and she did not like it. She felt that he needed to respect her better than he was as he was the one who had broken up with her. She did not want him back and to show him how much she despised him, the mistress got him to lick her feet as she fucked another man. He also had to lick the other man's feet.
Lady Shay was fed up with trying to get her man to change. He had driven her to the wall and she did not have many options left. She chose an extreme one before she thought of leaving him. The mistress sought to cuckold her man and make him see that she was desperate for them to come to an agreement. And she plotted it to perfection before she executed it. It worked.
