Can't stop my mouth, my big mouth...

So, I wrote this story once upon a moment. It was rubbish, but for one part when the guy says to the girl, the fantasy:

"You are my crust. You form on me, congeal and coat my thoughts. You are my end of days, and at the end of my days you form on my heart, gnaw through it like plaque, and when I awake into the afterlife, I carry you on scales over my skin.

You are... my crust; you have emerged on the fringes of my life but, when you break away, you unleave me and expose my unsatisfied, molten mass. My crust, peeled off unhealed to let blood, clinging to me at the edges, inevitably falling away and lost."

Simply, she lives in my lap. My motivation is more than the connective glance, it is the connective word. Her text is there, is it unwitting, authentic, just rare?
