Mistress Kinsley wanted to use this guy so she used him and she got the favors she wanted. She had promised him sex in the process and the guy was excited. But when it came to honoring her promise, she could not do it. She had to find a way not to do it. And she used her dirty boots to do it. She pretended that she was turned on by weird things like him licking her dirty boots until he got pissed and left.
