Going to bed with my window open, in case he decides to pay me a visit, watch me sleep for a bit before peeling back the covers, exposing my half naked, unconscious body. Maybe stroke himself to the sight of me sleeping so peacefully, completely unaware of how I'm about to be violated by him.
He'd use his knife to remove the rest of my clothes, his belt to tie my wrists to the iron bars of my bed frame, my panties to gag me and keep me quiet when I inexorably do wake from him forcing his cock inside my tight little cunt.
I'd stare up at him with wide, fearful eyes full of tears, but I would keep quiet when he holds the blade of the knife up to his lips, warning me, the moonlight reflecting off the blade and casting an obscuring shadow across his features.
He'd tell me to be a good girl and keep quiet (or else) lest I wake up the whole house and ruin our fun. Then he'd press that knife against my throat to make sure I comply, covering my mouth with his free hand to make sure my whimpers and cries are contained while he breeds me, flooding my little virgin pussy with his cum.
"that's a girl... you took it so well for me, don't you worry princess, don't cry, I'll be back tomorrow night to use you all over again."
