Mistress Roberta caught her slave looking at her ass and she was angry. He was a slave and he was not supposed to look at her in a sexual way. She had to teach him never to do that again so she farted on him. She did it while facesitting on him. Mistress Roberta told him he was only good for licking and smelling her stinky farts and nothing else.
Mistress Roberta did not like how much noise her slave made. She asked him to take it down a notch as she was trying to sleep but he thought that he could get it back up once he was sure she had slept. She was startled by the noise again and she was so pissed that she facesat on him and she farted on him to punish him for it.
