flashback... I had some knife play this weekend and talk about "mind fuck" it is so erotic. The lines which are left only make it easier to drift back to the moment.
Trust is number one, one of my "mind fuck" moments had me staring at the tip of a knife as it was held out in front on my face as the Dom whispered in my ear, before I saw the knife move, his hand was pounding on my chest and I almost pissed my pants in a good way. If I wasn't excited my knives before this I am now.
