This is my first ever fan-fiction. I wanted it to be the reader finding out she is the half sister to the Winchester brothers. Thought I'd make it a bit different and set it in England where I live. Feel free to leave feedback and helpful criticisms. This is my first fanfiction so I apologise if it's awful

Chapter 1

It was just an average day for you. You were getting dressed ready to go to college and complete your final exams, then you were a free agent. You were hoping to get straight A's so you could go to Oxford university. For the past two weeks you had been quite stressed revising and worrying I'm case you failed an exam. You went downstairs to find your mum making bacon butties. Your favourite. After downing the delicious breakfast you bid her goodbye, grab your bag and a light jacket and leave for college.

You headed back home after a rather stressful exam which you hoped you had done well in. You went inside and dumped your bag and jacket in their usual spots in the hallway and entered the living room to find two strangers sat talking to your mum. You couldn't help but stare at the rather handsome men. You could instantly tell they were brothers. They had the same alluring green eyes. One was taller than the other with longish brown hair tucked behind his ears, lean yet muscular and gentle features. He was the younger of the two. The older man was a few inches smaller with short, neat brown hair, well toned and muscular body and the face of a model.

"y/n. This is Sam and Dean." Your mum introduced them. "Hi y/n." The tall one, Sam spoke to you. His voice soft and gentle. You nodded in response, weary of them. You could tell they weren't from around. "Y/n. There's something I need to tell you. You may want to sit down." Your mum offered. Her tone was soft yet a little shaky. She was nervous. You sat down near your mum and couldn't help but notice the men watching you avidly from the corner of your eye. Your mum took a deep breath and your heart began to race. "Y/n, I haven't been very truthful about your..." "Father." You finished. Your mum nodded. The man she had always tried to convince you of being your father had always hated you. He had often beaten you threatened you but loved your younger sister very much. For a long time you had thought he wasn't your real father. There were just too many differences between you and you looked nothing alike. Among many other things you were the only person in your family with green eyes. Your mums were blue and your 'fathers' were brown. You were beginning to see now why the two strangers were there.

"Let me guess my real father has been found dead somewhere." You continued getting slightly agitated. "Not exactly. He is dead but has been for some years now." Your mum tried to remain calm. "Then what? And why are they here? Who are they?" You began to get angry. Both men seemed a little shocked. "They're your brothers. Well half brothers. They found some old letters me and your father wrote to one another and came to see if what they had read was true. Here see for yourself." She handed you a hospital letter along with a handwritten one.

"John Winchester. That's who my real father is?" "Yes. He came over here on a job with some friends of his and I bumped into him as at the time I was upset after arguing with your... Anyway one thing led to another and we spent the night together." You were trying to process everything your mum had told you and noticed that both men were listening attentively. "He left not long after saying he had to go back to his two boys. Of course a few weeks later I found out I was pregnant. I went for a DNA test to be certain and well you see the results for yourself. I wrote to him and told him you were his. He offered to help in any way he could. He even wanted you to meet his two boys. I considered leaving but we were already married and when you were first born he was great with you. He only changed once your sister was born. John wrote to me for a while after you were first born. Asking about what you looked like, your name, what colour your eyes and hair were. He continued to write and every year once a year I would get the letter on your birthday. When he found out you weren't happy he offered to have you live with him and his boys. But I couldn't just let you go. You're my daughter." Your mum began to sob quietly. The thought that your real father not only knew about you but wanted you to live with him hit home hard. But sadly you would never get to meet your real father, to find out what he was like and if you had the same interests. It made you both sad and angry. "So after all this time. You decide to only tell me this now?" You snapped. "Well that's because we showed up asking questions." Dean commented trying to make a joke but received a swift elbow to the side off his brother. "You weren't ever going to tell me were you?" You pressed. "You would have wanted to find him. I couldn't let you go into their lifestyle, especially since that's what got him killed. I didn't know he had died until they told me. He was one hell of a guy too." Your mum blew he nose on a tissue. "It still would have been nice to know who my real father was. Besides its not up to you what lifestyle I live. It's probably a hundred times better than being beaten up for looking at someone wrong." You were standing up now. You could feel your anger rising from your stomach. "He was a hunter!" Your mum snapped back. "That's hardly a bad lifestyle." "A supernatural hunter!"

Ah you thought. That was different. You had never met a hunter yourself but your friend at college had an uncle who was one and she had told you of quite a few times when her uncle had almost died because of what he did. It was a very dangerous job to do. You didn't know what else to say. Your mums reply had left you feeling mixed and confused. Instead you just sit down quietly trying to figure out everything you had just been told.

Your mum got up and left the room still sobbing. You wanted to go after her and apologise for shouting at her when you knew she was just doing what she thought was best for you. But you knew she just needed time to cool down. "Don't be so hard on your mum. She was just doing what she thought was best." Dean told you seriously. "He's right. You wouldn't have wanted to grow up the way we did." Sam reasoned giving you a soft look that you couldn't be mad at. You sighed and looked down at the papers your mum had given you. "So. Now what?" "We had better get back. We only came to see if this was all true." Dean replied as he stood up and headed for the front door. "You came all this way for an answer that could have been given over the phone?" You quizzed also standing up. "Ok so curiosity got the better of us and we wanted to know what our half-sister looked like." Dean replied snarkily. "It was nice meeting you and your mum y/n." Sam also stood up. "Wait a minute. You can't come here wreak havoc then just leave. If your my half brothers then I want to know a bit more about you and about our father." "We aren't ones to play happy families. Besides what we do is nasty stuff. Not something for little girls." Dean retorted and turned around to leave, Sam beside him. You flew in front of them and blocked their path with such speed you could tell it surprised them. "I'm no little girl. I can handle myself well enough. I've seen some nasty things myself. May not be the same but I don't scare easy." "Kid. You could get hurt or even killed. "Guess I'll have to take my chances then." "No. Just no. I'm not having your blood on my hands." Dean pushed past you and out the front door. "Give me a sec to talk to my brother." Sam jogs after Dean.

Sam and Deans POV

"Dude, what the hell?" Sam called after his brother. "What? She can't come with us Sam it's too dangerous. End of." "We could at least go out for coffee or something with her. She's not asking to come with us hunting. She just wants to get to know us better that's all. Where's the harm in that?" "Everyone who gets close to us ends up getting killed. She's got a home and her own family. We don't want to screw that up on her." "Come on man what's got into you? Look ill give her my number that way if ever she needs us she can call." Dean rolled his eyes and got into the drivers side of the rental car. Sam ran up to you and gave you a card with his number on and told you if you should ever need them to give them a call before leaving.

Your POV

It had been a few days since you had found out who your real father was and that you also had two half brothers. Your mum hasn't spoken to you and whenever you were in the same room together there was an atmosphere that made one of you leave the room. You were fed up and decided to go for a walk despite it being dark. You knew your neighbourhood quite well and always felt safe no matter what time of the day it was. After a few minutes walking you felt like someone was following you and turned around. No one was there. You continued to walk but still felt like you were being followed so you sped up and flew round the nearest corner then hid. Waiting to see who was following you. After a few moments no one appeared so you peaked round the corner. The road was empty. Not a soul in sight. 'Paranoid' you thought to yourself. You turned around to carry on walking when your eyes met with two completely black ones. Reacting on instinct you punched the figure in the face and bolted for home not looking back even once.

Once home you quickly open the door and slam it shut. Quickly locking it behind you before leaning your back against the door to catch your breath. You had no idea who or what it was but it had made you feel very uneasy and frightened.
