When this guy noticed that she was dealing with a guy who was into things she did not want to get involved in, she had to make him change course and she did this by making him learn to obey her. She did this by forcing him to lick her boots and especially the soles as she watched. And after that, the mistress told him never to forget what she was capable of.
Mistress Jenni wanted to dominate this guy and she did it with her boots. She did not care what he felt and she wanted him to learn that he could not be a nuisance around her and expect any sympathy from her. So she put a stop to the nonsense by cruelly making him lick her high heels. He had no choice but to do what she wanted him to do.
