This guy was horny and wanted to get it on with lady Stefanie but she did not feel the same way. She did not feel like doing anything with him and she told him as much. He tried to convince her but she did not want anything to do with him. So she used her boots to humiliate him and make him realize that she was not in the mood to do anything with him.
Lady Stefanie knew this guy was a loser and he would do anything she asked him to do. So she used that to humiliate him and have fun at his expense. The mistress flirted with him and he thought she wanted him. He fell for her trap and she got him licking her sexy feet and doing all manner of things to her feet hoping to have it lead to sex but it did not.
