It took Mistress Sonia's chastity slave 2 years to finally accept the fact that Mistress was absolutely serious about never unlocking Her cock property ever again. That was a huge struggle!

Mistress' chastity device was a custom made surgical steel one that was at least large enough to allow Her cock property a little room to grow and be able to feel even as if it was free when it was at its most flaccid state. At the end of Owning Her slave for 3 years Mistress decided to change all of that and permanently re-locked Her cock property in a custom steel device that is so small that even when Her cock is its most flaccid it is still being constantly squeezed by steel. There is no ability to move or grow at all!

That was 6 months ago. The constant pressure of the steel cage, being constantly horny and not being able to move or grow at all is driving Mistress' slave totally nuts!

Exactly how Mistress Sonia repeatedly tells Her slave that She enjoys it to be and it will remain permanently then smiles sweetly.
