Derek is pinned, Stiles' strength immovable, and for a moment, he's reminded of all the times he used to grab and push. Just to touch, just to hold onto him, just to be close when he couldn't justify the urge. It sinks it in, that feeling of powerlessness, the fact that Stiles isn't human, isn't the boy that Derek craves, but has never had the words to say. He jerks, twists in Stiles' hands, looking into those brown eyes and there's something absolutely intoxicating about the feeling of thin fingers and soft hands pinning him down and those brown eyes. He hates himself for how this thing can pull those sparks of feeling from him that Stiles never had the right senses to see.

It catches his breath, makes him gasp when those browns go black, makes his heart still with a shudder. That flutter of lashes, flirtation that makes his skin crawl with conflicted feelings. He takes a breath, tries to keep his face like stone as he looks into Stiles' eyes. There's a moment, at the second question, the way emotions curl and flicker on his face before his control slides back into place. However the word that slips off his lip is as damning as any look.

"Everything."

It's soft, but his gaze is steely, like glaring can somehow keep the demon from making something of it. From using it to hurt him.

"Whatever you want. You leave everyone else alone, you let him go, and you can have anything from me you want."

Self-sacrifice, your name is Derek Hale. God, he was so fucking easy wasn't he?
