I clamp my hand around his mouth and pull out a knife from one of my expanded pockets. Sure I've silenced them both but I find that removing their abillity to make noise but not struggle really ups the fear factor for this next bit. Here's a fun fact, studies have been done to people via shocking them and asking them about to find out exactly which parts of the human body are most sensitive to pain. Turns out that the forehead and fingertips are extremely sensitive to pain  along with the arches of feet, shins, elbows and funny bones. Feeling him squirm under me as the tip of my knife approaches his forehead is simply intoxicating, I may have picked up a preference for manual torture after the Dursleys. I feel him writhe and wriggle trying to escape as the tip of the blade is pushed into the skin of his forehead, a little trickle of blood flowing from where I push it against him. I look into his eyes and I can feel the terror and hysteric panic flowing off of him like a tidal wave of emotion. The grin that splits my face only serves to make his eyes widen and his fear sweeten. The writhing get's predictably more irate as I begin to drag the knife roughly across his skin I can feel the feedback of his cranium so I know I'm not just slicing skin but carving bone and that he can feel it.
