Mistress Tiffany wanted to control her husband because she did not like how instinctive he was. She feared he could cheat on her and she wanted to make sure it never happened. So she used chastity humiliation to do so. She made him wear a chastity device and she turned him on to see whether it was working and as he got hurt when his dick got hard, she knew it was the right decision. She hid the key and only opened it when she wanted to ride it or to be pounded by it.
Mistress Tiffany and her friends did not like how this guy had tried to seduce all of them even though he knew they were friends. He had to be punished for being too much. He had to learn to look for one girl and stick with her and the mistresses felt chastity humiliation was the best way to punish him. So the mistresses bought chastity devices and made him wear them for some time.
Mistress Tiffany's boyfriend is hot. He is well built and he is handsome. He has a deep voice and he dresses nicely and smells nice. She does not want other women preying on her so she takes great care to make sure that he does not cheat on her. That is why she loves to make him wear a chastity device not so much to humiliate him, but to make sure he would not do anything with his dick.
