Mistress Nyx was not interested in having sex with her ex but she was definitely interested in messing with him. And she made sure that it was through controlling his sexual activities. So she teased him as she knew his weaknesses then had him wear a cock lock. Thereafter, she hid the key and he could not remove it or do anything with his dick other than to pee. She had a good laugh about it.
Mistress Nyx likes to date weak men so that she can force them to do what she wants. She has dark fantasies and she loves to live them out on her boyfriends. Today she forced her chastity femdom on her man who had not even cheated on him. She made him wear a cock cage and then played with his dick to get hard knowing it would not fit in the cage.
