Just what is it about knives that is such a turn-on?
Is it the skillful and masterful way He handles them?
Is it that He invariably uses a big, mean, and lethal looking knife?
Is it the look in His eyes when He begins to run the knife blade over my skin?
Perhaps it's the feeling of the knife on my skin, at times warm and then cool when turned slightly.
Perhaps it's the thrill of not knowing what is coming next.
Probably it is all of the above and more.
Knife play is different than a beating, or wax play, or punching, or caning, or spanking, or flogging. Knife play has elements that are more unpredictable. Harder to define.
I'm fine with that.
