I think that there is something quite erotic about being placed in a brace that immobilizes a limb or two. I have always played around with trying to splint one leg, or use an old brace to restrict my leg, or put my arm in a sling. There is just something about it. But I think it would be even more of a turn on if someone else was putting me in that brace or in multiple braces and doing whatever it was they wanted.
So where do I volunteer?
