This mistress facesat on this guy and she also made him bury his face into her ass and smell her farts. That was his punishment and she did not care what he felt. The mistress was only interested in dominating him and that is what she did to the guy. He was scared of her after what she had done to him and he toed the line and did what she asked.
When this mistress realized that her friend had been going behind her back to do the very things that she did not want her to do, she had to show her that she was serious and that she would not allow for those things to continue happening. So she used her BBW ass to smother her friend and to teach her a lesson she had never been taught before in her life.
