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.
