Lady Susan is an adventurous girl. She loves to try anything and everything, which is why she chose to try foot fetish. She had never tried it before and she was super excited about it. The mistress went ahead and she enticed a guy who she lied to that licking her feet would make her horny. He did it but was shocked when she just laughed at him and did not get turned on.
Lady Suzan was pissed to learn that this guy was making fun of her feet. He had been subtle about it at first and she did not notice. But when she realized what he was doing, she was angry and she used the same feet he had been making fun of to dominate and to humiliate him. The mistress made him regret what he did and he asked for mercy but she ignored him.
