Mistress Jardena wanted to dominate this customer because he was unruly and he did not do things the way the mistress expected him to. She was disappointed in him and had to make sure he learned that he had to uphold his end of the bargain even as he demanded good service and wanted value for his money. He had to lick her bare feet as well as her high heels.
Mistress Jardena was angered by the way this guy behaved and she had to make sure he did not behave that way again. To make sure of that, she used her high heels as well as her bare feet to trample him and also to kick him. It was painful but she did not mind as that was what she wanted. The mistress slapped the shit out of him as well and that is how he learned his lesson.
