Lady Nora and her friend mistress Kim had beef with this slave and they had to do what they had to do to make sure he learned never to piss them off again. The mistresses felt that the guy had been taking things for granted and they wished that he stopped doing it. But he did not stop and they had to punish him for it which is why they tied him up and then choked him by facesitting him and smothering his face with their asses.
