Key Locket/Pendant

I guess what kind of cage and lock - if it intergrated lock the key are really long - one cut down the key and make small enough to fit into a locket -
I can post a pic of my key if might give you ideas

 

Have you thought about just wearing the key around your neck? I suspect your husband would love to see that.

I feel like that is something you could find on etsy, but I can't point you to any specific one. The one I concern I would have is if it comes open when you're not paying attention and you lose the key...

 

One way you could do that is put the key/keyring directly on a string / wool / cotton / around your neck, then all you have to do is snap it (could be pre-weakened with scissors) or the knot come undone, and oops! the key must have fallen off.

Or just make the whole key and chain you're wearing 'disappear'. Mention something about feeling something in a particular location but you didn't realise must have been the key falling off.

Another way would be to swap sweaters/t shirt/top just before you leave (the one you're wearing is too hot/cool/wrong colour), then when you arrive the chain must have come off when you swapped your top.

Another way would be to get another similar old key and throw it out of the car/train/bus window in a place where you won't be able to stop or pick it up again, saying, "I don't think I'll be needing that again!". Then he won't know when he's going to get unlocked again.

Or when you have teased him to the point he thinks you're going to unlock, tell him you left it at home because you intend all the pleasure to be yours.

Another way is to get the spare key, and file down some of the 'teeth' so the key no longer operates the lock. "Oops, the lock seems to be jammed" Diverting attention to the lock, means that the thought of using the spare that is at home doesn't occur.

Ooh! I can be such a switch sometimes... (but I do prefer being submissive)

 

etsy sell quite a few different styles of locket pendants where you could hide a key inside.

 

That is such a devious thought.. did you go through with it?! I will keep your post away from my wife's view....

 

Id think someone as lovely as yourself should have a gold key as jewelry, as a symbol of locked chastity. Keep the real key in your purse n I LOVE the idea of filing the real key to keep him locked n frustrated!
