Goddess Kiffa needed to torture and to dominate this guy and she did so using her humiliation fetish. She did not care about the guy and all she was interested in was making sure that things worked out the way that she wanted. That is what and that is how she had her fun at his expense and all he could do was endure it all without any question whatsoever.
Goddess Kiffa did not want to punish her slave. She was out to scare him as he did not know what she was capable of. She used her high heels to tell him what she could do to him and he was scared shitless and he did not want any of that to happen to him so he obeyed her at all times to ensure it never got to that point.
