This guy was too obnoxious for this mistress to ignore. She had to deal with him the way she does to those who are like him. That is how the guy found himself being dick trampled. He felt pain that he had never felt before and he cried like a baby but the mistress did not care about any of what he felt. He learned his lesson after what she did to him.
This guy likes to talk a lot and this mistress was not in the mood to talk or even to listen. So she forced the guy to do what she wanted and she cruelly tortured him by facesitting on him. She did it to both make him feel pain, humiliate him and also to shut him up. And it worked the way she wanted it to. He learned to shut up when with her.
