In less than a minute from contact the infection took hold of her as nanites crawled from inside her irises to cover her entire body.
He watched in silent shock at the transformation.
Bringing her to the very height of her beauty; the nanites slowed for only the briefest of moments, showing him everything thing she could ever be physically and by God was she stunning! He gasped in awe at her absolute perfection, the cruel, cruel taunt displayed before him as she gave him a glimmer of her classic smile. A smile he inwardly knew was not real, yet he was as mesmerized by it now as he was when she was alive.
Though yards away he started to reach out to her, to touch her, when the vicious nanites true job finally kicked in. Her momentarily perfect eyes implode in on itself as though a fine, blacker than black silt were being sucked into an even blacker than black hole.
Only then did it occur to him to run, before the nanites sensed his own body, when he saw the first hint of blackness encircle the fingertip of his still outstretched hand.
Too late…

A guy sitting across from me on the train had absolutely filthy nails. My muse took a wicked flight of fancy as one of his finger tips looked like something alien was slowly devouring it. Amidst my repulsion, and fascination on how a relatively clean looking person can have such crusty nails, this whole scenario above happened in that most dangerous of places – my mind.
Let’s hope my fellow slicers are having a more benign mental state – check them out…

Oh, so creepy to think about…eesh!
Wow. This sounds beautiful. I read it out loud and it is Toni Morrisonish. Deep and scary but a linguistic portrait. To be able to look at crusty nails and make this story up about them is pretty genius. It also reminds me to not be so shallow. He almost saved her, so what he has crusty nails.
Love the way your mind works.
Let’s hope other slicers (me, for instance) are having such inspired thoughts and writing some flash! Love it!!
