A while ago I had the cunt-wetting pleasure of going into a sword store with my guy. Dear lord it was hot.

He knows how to handle a blade. Did saber fencing for years.
So, we wandered around the shop, looking at various pretty sharp things. Every now and then he'd draw one of the swords, play with it a bit... and the look he got on his face was the same intent gaze that he gets when he's hurting me.
I think a blade fetish sprang fully-formed into my head that day!
