My preference is no mask unless its just for the initial taking.
I want her to see my face throughout. I want her to remember everything about me...what I look like, what I smell like and most importantly what I feel like.
To deprive her of my sight, hoods, blindfolds, forcing her to look away if needed are my preferences. By far though, I want her to remember me physically, I want my image and voice, my touch and scent burned into her mind forever, so when we cross paths again ( because we will) she remembers me and everything I forced her to do and endure. I even imagine her seeing me and paralyzing at first, then perhaps rubbing a point on her body where she carries my mark while staring at me in fear, remembering how I made her feel. I could talk about this part of me forever.
