Mistress Jardena did not like how this guy misled her. She did not mind as long as he did not know or do it intentionally but according to her, it looked intentional and she was not going to let it slide. That is why she opted to facesit him and choke him. He was turned on by what she did to him with her bare ass but that did not take away from the fact that it was humiliating and it scared her.
Mistress Jardena was pissed at the way in which this slave was irresponsible. She felt that she was egging him on by not punishing him for his many mistakes. So she changed tact and she used her slaps and her high heels to humiliate him. He had to endure hard slaps as well as painful high heel trampling. It worked as he feared her and did not want a repeat.
What mistress Jardena wanted to do to this guy was to facesit on him and choke him in the process. But he resisted and she had to use her high heels to trample him so that he realized he had to do whatever she asked him to do. The mistress did not mess around and that is how she got him to sit still as she facesat on him and smothered his face with her butt.
