Mistress Nica wanted to dominate this guy and she did it with her leather leggings. The mistress had to make sure that she smothered him and choked him so that he would take her seriously and do what she asked him as opposed to ignoring her or even taking her for granted. When she was done smothering him and choking him, she had accomplished what she wanted when she started.
Mistress Nica paid this guy a lot of money as a bartender at her club. He did not do his work as well as she wanted him to and before customers came in, she saw him naked at work. She was pissed and she took him to the back of the restaurant and she ballbusted him and taught him a lesson she was sure he would not forget in a hurry.
Mistress Nica did not want to have a lot of issues with her slave but he was very argumentative and she had to find a way to deal with him. After thinking about it, she settled on using her boots to trample him. And if he did not stop, she was willing to do it with her horse. It was all up to him what method she would use to punish him.
