This mistress knew this loser had been paid and she wanted a little money from him. She had made him wear a chastity device so he was not able to get a release. She was the only one with the key to the device and she offered him the chance to remove it but he had to pay her. He jumped at the chance and gave her the money she asked for.
Lady Suzanne knows she is beautiful. She truly is. And she loves to use that to have fun. Unlike other mistresses who use their hot looks to gain favors or make money, she uses hers to have fun. And for her, fun is chastity fetish. She likes to make guys do stuff that they have never imagined they will ever do. And that is how she always has her fun.
