Lady Stefanie likes to use the latest gadgets to dominate and humiliate anyone she wants to humiliate and dominate. Today she chose to do the same to this loser who had pissed her off. The mistress used a chastity device that she had bought to do it. She then teased and denied the guy in order to get the chastity device hurt him. It was great for her to watch.
Lady Stefanie wished that she had known about chastity devices and chastity femdom earlier because she would have ensured no one ever cheated on her. She made her husband wear a dick lock in the morning before he went to the office and she kept the key. She opened it in the evening when he got home and that way, the mistress made sure he would not cheat on her.
