I want you to send your keys to Me. And maybe I'll keep them safe, and maybe I might just lose track of them. Maybe they'll get lost in the mail and you'll be stuck in that cage... maybe you'll never get out of it. Maybe your dream of staying in chastity for a Mistress as beautiful as Me will finally come true. Maybe I'll send your keys back to you, and maybe I'll just keep them. I don't need your dick, and you know that you don't need your dick. So, what's to fear? Stay in your cage and send Me your keys.
