Mistress Khali was pissed that her boyfriend's friend had the audacity to hit on her. She did not like it and she felt that it was important to send a message to him. That is why she opted to use her facesitting fetish and her feet to trample the shit out of him. That way, he would never try that nonsense again with her. He got the message and never did.
Mistress Khali was enjoying her own company when this guy tried to chat him and to spend time with her. She told him she was occupied but he did not want to listen to her. She had to punish him to make him stop disturbing her and she did it by making him a living ashtray and humiliating him as she chatted with her friends. He also had to endure high heel trampling.
Mistress Khali had beef with her slave because of the manner in which he did things. She did not like it and knew that it was up to her to punish him. So she used her dirty and smelly shoes to trample and choke him. She only stopped when he peed his pants and she knew he had learned his lesson. But she warned him of worse if he did not change. He did.
