Funny.
The one thing you really want doesn't really want you.
He doesn't need you.
Yet you are his.
You would give up everything for him and in many ways you already have.
Your soul.
Your passion.
Your drive.
Just For a moment in time.
To feel him.
To kiss him.
You can't say no.
And when he is gone.  
He haunts you in your dreams.
He crawls around your mind.
He eats through your heart.
He is that thing that rips your spine.
Your lover.
Your demon.
Your familiar.
Eating and consuming the last of you.
