[ He lets her turn around to face him; doesn't stop her, and he meets her eyes with his own; dark, veined, filled with hunger and desire for her. Something he can't quite shake, but he's not fighting it; not about to latch onto her neck and feed on her either. He just maybe wants her to see what he is when he's not faking at being human 90% of the time these days. Damon brushes his fingers across her cheek, listening to the sounds of her breathing, focusing on it through the beat of the music, and he drops his gaze to watch the rise and fall of her chest.
He could drink from her, satisfy that blood lust, and it would be all too easy to keep going; get rid of this need to feed, but he wants so much more than that. He always wants more. It has been something of a problem of his since well over a century ago. Nothing's ever enough for him. Or maybe he's just never known what it's like to be truly satisfied. His parents doted on Stefan, Katherine never loved him.
And Elena…
Damon bites down on his bottom lip, hard enough to draw blood. (It's possible she could have gotten a glimpse of his fangs.)
