Favorite BDSM-themed fiction?

Hi folks, hope you don't mind if I butt in!

Has anybody read any really good bondage-themed stories? Care to share? I've seen a few good ones, and I'm always eager to find more. It's awfully draining to find good stuff, though, because you have to sift through an awful lot of well-intentioned but poorly executed dross to find those bits of gold.

I'll continue this thought in a comment. But please, share good bondage fiction!
