Mistress comes back from a girl's trip, and she finds the house in a mess and her slave was just walking around the house in her robe. He had taken over and felt like the owner around the house. He didn't hear her come in and when he saw her, he became speechless and all the courage that he had, vanished into thin air. She drags him to the red room, makes him undress until he has nothing on any more, then she makes him lie down. She tramples on his back and sits on him.
When it comes to dominating people for fun, this mistress knew that the best bet for her was to use her smothering and choking fetish to do it. She also had to make sure it was as painful as it could be and that is why she stripped the guy naked and she tied up his balls. Before long, she had crushed his balls and made sure that he was in the pain of his life. His inconsistency had cost her a lot of money and he had to realize that and change.
This mistress did not like how much her slave lied and she felt that if he did not stop his lies, he would be a huge liability for her company. So she had to force him to stop his lies. She did this with her smothering and humiliation after she had tied him up and stripped him naked. He never lied again as he did not want to have that experience again.
