Did you really think that I wouldn't find out? I should have known better than to trust you but you've been letting yourself out of your cage! Not only are you a disobedient little prick bent on jerking off without permission but a sneak about it too? You would have done better to confess but here we are. A bigger, stronger, heavier lock ought to teach you a lesson and remind you of your sin. As for the keys? I'm keeping them in a safe place where you'll never find them.
