Goddess Nika was out to send a stern warning to this guy so she chose to use her big ass to do it. The mistress first of all trampled him and when she was done with doing that, she ass smothered him and enjoyed how she facesat on him. Farting on him was the last thing she did to him before she was done with him. He went away degraded and humiliated.
Goddess Nika was looking for a way to make some good money at her place of work and she found it when she realized that her boss was into her and he wanted to have a relationship albeit a secret one with him. So she used her brainfucking fetish to control him after she had fucked him good. She was able to dominate and control him for her own benefit.
