Sister Winchester (Castiel story)

Hey I am Alexa Winchester, I'm 21 years old and I was in college to become a teacher but i had to leave because Dean needed me. Speaking of which I should probably tell you why. Dean picked me up from college he told me it was because dad was on a hunting trip and hasn't been home in a while. This is our job, dad wanted us to help him but Sam and I wanted to do something else. The job runs in the family its sort of a "family business" with me and my two older brothers Sam and Dean, our dad raised us in the business. Dad used to say all the time before starting the job what we do, "saving people, hunting things". Anyway I let you get to the story now.
