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.
