You have been such a good boy for staying alll locked up nice and tight for me with no complaints. I want to give you a gift. Something that will ensure that you never forget about me. I want to release you and please you. But I want you to swell in your cage one more time for me. I love teasing your caged cock with my hot breath and soft tongue. Clicking my long sharp nails along the cold steel. The bars begin to press deeply into your aching cock and I begin to crave more suffering from you. I drag my key across your cage and talk about how nice it would be to release you and really use your cock for something productive. Before too long, I realize that I would be crazy to let you out. I think another few weeks should really make you appreciate the things I have planned for your cock once it's allowed out for air.
