Some people love it, some hate it. There are lots of way to deal with it, most folks have their preferences, but anyone who has worn one of the common chastity cages out there has experienced it - the little "click click" from the lock on a chastity belt.
Pretty much every device I've tried has it, and I suspect it's all the louder on a metal belt. Some dommes love knowing that their sub is just a little bit "out" by the click. And some subs love the excitement that comes from the more self-conscious "do they all know?!?"
This week I found another work around. While some prefer just on the cage to soften it, I had used to use a rubber band around the whole lock & cage, before find out how well outdoor strength velcro would work (indoor strength won't make it past a couple showers.)
But this simple work around was new to me, get a pedometer.
My wife signed us up at the Y to track how many steps we take (or don't) and it makes a similar subtle shifting noise when I walk. So if you want to cover the sound of your clicking belt, well I figured I'd throw this suggestion out to you all.
Not that it'll help. I'm sure all the women in the office already know full well you are locked up by your dominant. At least since she circulated those pictures in the office e-mail...
Oh wait, you didn't know about that, did you? :P
