The Evening Star. (A Supernatural Lucifer Short Story SMUT)

Your name is Yvaine and you're a nephilim. Your father was an angel and your mother a human. You never knew either of your parents; your father was executed because he had relations with a human, which is strictly forbidden by Heaven, and your mother died while giving birth. Normally, a nephilim is killed while the mother is still pregnant with it or shortly after it's birth; but you were incredibly lucky and a wondering archangel decided to hide your existence from his brethren.

You live as a normal human in an orphanage for the first ten years of your life, until the spell that had hidden your angelic grace breaks and the angels discover that a nephilim has somehow managed to survive. While running for your life from angels and demons, you run into the rogue archangel once again and he takes you under his wing. He teaches you everything you need to know about life as an angel as well as all of his favorite tricks.

The two of you part ways on your eighteenth birthday and after years of being on your own, you end up becoming friends with the Winchester brothers. You help them with jobs whenever they ask, but never informing them that you're not completely human. They soon learn the truth though when the angel Castiel appears and all hell breaks loose...literally.

You thought your life was bad when you were being hunted by regular angels and demons, but that was a walk in the park compared to being hunted by the Devil. Lucifer wants you as his mate and what Lucifer wants...he usually gets.
