Supernatural: Adopted by two hunters

My parents were killed by Azazel or better known as the yellow eyed demon. I went to live at numerous foster homes, keeping my hunting a secret. It always ends the same though. I get kicked out and went to another home where they were just there for the welfare checks. That was what it was like until I went to live with two guys named Sam and Dean Winchester. I do get in trouble a lot and they try to keep me in line but they aren't very good at it.
