My Mistress gave me two matching chastity cages and has instructed me to find another sissy and have us both lock up. Mistress also gave me two keys, but only one of them works on one of the cages, but we don't know which one it goes to! I let you pick which cage you want and I take the other and put it on. You hesitate putting yours on, but I help you out and lock you up so we can start playing together. We then discover that both of the keys are duds and neither work so now my Mistress has us both locked up with no escape! At least we can still masturbate with dildos~
