You've had your cock locked up in chastity for me and at this point you're full of sexual frustration that you'll do anything to be able to relieve a little pressure. I've decided to allow you to use your dildo and fuck your ass, but no matter how horny you get, don't even think about taking that cage off. This is the only sexual satisfaction you're allowed to have, so you better work that cock really good! When you're in chastity all the time, you'll learn to enjoy anal, because that's all you get!
