When this mistress learned of chastity devices, she had to get one. She was so fascinated by what she could do to her boyfriend using the device. She made him wear it and it was not hard for her to make him do it as she was sexy and she knew how to use seduction to make him do whatever she wanted. Then she teased him and enjoyed how tortured he was since she had the chastity key and he could not remove the device.
