Goddess Katrina wanted to degrade this loser and she felt that using foot fetish was the best way to deal with him. She chose to make the guy lick her feet and do other humiliating things. She did not care what he felt and what he did. All that mattered to her was that he licked her feet the way she wanted them to be done and he had no choice but to do it.
Goddess Katrina wanted this guy to cum and she wanted to do it without touching him. So she stripped slowly as he watched and she enjoyed erotically touching herself as he watched. She talked dirty and she swayed seductively as he followed her movements. He was so turned on that he did not realize how he came in his pants. He could not believe it but she was that good.
Goddess Katrina wanted this guy to feel pain and to be humiliated. So she used her high heels to trample him. Besides that, the mistress forced the guy to lick her shoes and her socks. He tried to plead with her not to continue dominating him but she just listened to him and ignored him as she wanted him to learn that she would not tolerate or condone his errant ways.
