Mistress BlackDiamoond had a slave who was a know-it-all and she did not like that about him. And it got to her nerves after trying to tolerate the behavior for a little while. She had to change him and this was done through dominating him with a dildo. He was made to deepthroat it and gag on it before it ended up his butt and he felt untold pain as she did her thing on him.
