Mistress Anni needed to scare her landlord so that he could learn to cooperate with her. She felt that he did not and that was not ok with her. That is why she chose to use her kinky foot fetish to do it. He was shocked as he did not expect that from her and he was scared enough to agree to some of her demands and do what she asked.
Mistress Nyx was looking for a new pastime and she settled on using kinky foot fetish to do it. She knew that the best way to do it was to turn this guy on with her hot body and then make him do whatever she wanted and that is exactly how it went down. She did not regret it as it went according to how she had planned it out.
