Princess Kira was tired and she needed a good rest. But she did not get it as this guy kept making noise even after she told him not to do it. She became pissed to the extent that she had to punish him. The mistress used her trampling fetish to degrade him and ensure that he learned never to make noise for her again. She trampled his entire body to make it more painful.
Princess Kira's boyfriend had some annoying habits that she had tried to ignore but could not. She told him to change but he did not and she was forced to make him change. So the mistress used her trampling femdom to make him do the things she wanted him to do. The mistress knew it was now or never and she did it with all the conviction she could master.
