Enter the Sandman 

If you like music while you read, try "Mr. Sandman," by SYML. It's the right tone for David's state of mind here.

~ DAVID ~

I was woken by a small, gentle hand, the most beautiful voice in the world whispering my name, and the movement of the heavy quilts.

I jerked awake and started to sit up. But that hand landed on my chest, flattening right over my heart. 

The moonlight slanted through the wide windows of my bedchamber made her skin glow near-silver and turned her smiling lips dark.

"Zara?!" I croaked.

"I'm here. I found you," she whispered, pushing the covers aside completely and crawling into my lap.

I was immediately hard, straining, my chest tight with anticipation and overflowing love, desire and... something else. Something dark. 

Something was wrong.
