Princess Kitty wanted to show her boyfriend that there were many ways she could ensure his chastity. She knew he thought she could not ensure he did not cheat on her. So she made him wear a chastity device and she kept the key. He only had an allowance to pee and that was it. He could not do anything else with his dick without her allowing it to happen.
Princess Kitty likes to make money and she does not care how she does it as long as it is good money. Today she was punishing this guy for something she came up with. She knew he had money so she accused him of wrongdoing and she punished him with a chastity device. She humiliated him and let him feel the pain of having it before she made him pay her to remove it.
