Goddess Nika wore her leather pants and she used them to dominate this guy. She did not care what the guy wanted or what he felt. All she was after was to smother him because he had tricked her and she had warned him not to do it. So he had to learn that whatever she asked him to do had to be done or not done depending on what she asked.
Goddess Nika wanted to use her leather to dominate and that is what she did after she teased and controlled this loser.
