Lady Sue loves to get her hands on secrets because she knows that she can use them to make some good money or to get some favors done for her. That is why she had to ensure that she got her hands on them by trampling this guy with her pantyhose as well as high heels. She did not care what he felt. She had to do it and she had to get the secrets.
Lady Sue needed this guy to stop misinforming her and that is why she had to make him learn that doing so would attract a huge punishment from her. The mistress cruelly forced the guy to lick and smell her nylon pantyhose before she was done with him. That is how he learned his lesson the hard way and never messed up again after that. He always dealt with facts after that.
