If you beg I might give you the key to your chastity device

Aww, poor little loser. You wanted to play a little game and have me lock up your cock.

And now, you thought you could just come back to Mistress and ask me to let you out of your cage?

Ask me for, what is this, the key to your freedom?

Do you want it? Yeah?

You want to let your dick out so you can stroke it like the pervert you are, don't you?
