Mistress Dana did not want this guy to think that she was ok with the things that he did. He had messed up and she did not want to let the guy get away with it. That is why she chose to use her socks to put him in his place. She chose to choke him with her socks by making him lick as well as smell the stinky socks.
With her hot ass, mistress Dana wanted to make sure that she had teased this guy for fun and she did it. The guy was hooked and he liked what she did. In addition to that, the mistress had the guy lick her boots and this time she used her bare ass as well as her tits to get him to forget what she was asking him and instead do it.
