Mistress Claudia has sexy legs and she is a naughty girl. So it was easy for her to do what she wanted which was to use her feet to dominate a loser. She did not have a particular loser in mind and she left it open to whoever she would encounter. So she got out and she met a loser who she humiliated for fun and had him lick and suck her feet and her toes.
Mistress Claudia wanted her high heels to be licked. She asked this guy to lick them but he refused. He did not know that he was creating more problems than he would be able to handle. And that is why the mistress used her foot fetish to show him never to mess with her again. He got scared of her and did what he had been instructed by her to do.
