Tonight, you'll be taking me to a sensual, erotic masquerade party. I've approved your outfit for the evening, but there is one thing missing: a cock cage. I want you to remember that you belong to me, especially this part, and having your cock aching against the bars while I dangle the keys will be the perfect reminder. Actually, I'm going to wear them on a necklace where you - and everyone else - can see them.
