You were a vampire. Or a blood sucking beast, as people preferred to call you. But despite that, you never turned anyone nor did you ever take enough to hurt them besides the pinch from the puncture of your fangs.
You lived in Matlock Springs with other vampires who were much less caring and much more ruthless and cruel to their victims.
Their ruthlessness resulted in sn investigation done by two supernatural hunters. They went by the names Dean and Sam Winchester. Brothers.
You decided to lay low, cutting back on how much you fed and how often you went out. You only left your home when completely necessary.
Today was one of those days. You are starving due to having not been able to feed in a hot minute. You searched for a victim, quickly finding one and luring them into the woods.
You wrapped your arms around them and brought your lips to their neck, your fangs pressing into their neck but not yet breaking the skin.
But when you lifted your eyes, you noticed someone staring, causing you to quickly retract and push your victim away. You ran off, running straight home to your safe place where you thought no one would catch you.
But soon, you peeped out the window and saw a young man, Sam Winchester, coming up on your porch. He knocked on the door, causing your heart to thump harshly in your chest.
