I have changed some things about the vampires in Supernatural (from what I can remember). They are probably more like The Vampire Diaries vamps, not on purpose. I've been binge watching that and it's been a while since I've watched SPN. Please do not kill me 😂

You were wandering up and down the street, seeing late night runners go by. The urge to just attack had pulled through you, and you gulped and restricted yourself. You were one of the few vampires who didn't feed on humans or human blood — you fed on animals. Mainly smaller animals like rabbits or something like that, but you were more weak than the other vampires.

You would occasionally find yourself stealing blood from the hospitals to regenerate strength, but that was only if it was absolutely necessary for you to do. Most of the time it would take a long time for you to get so weak to a point you would have to feed of humans.

And tonight was one of those nights.

It's been about a year since you have fed on humans. The urge to just attack was very tempting to you, and you had found yourself wandering away to keep yourself from attacking.

The moon from above shines on you, and you felt a cool breeze on you. A runner ran past you and that's when you couldn't handle yourself.

You lunge forwards and take a bite out of the runner's neck, the blood seeping into your mouth. Fangs were formed inside of your mouth that had sank into the flesh. A loud scream emitted from the young female runner, and you drag her back into the forest, staying out of sight with each step that you took.

The hunger that you had been holding inside of you finally escaped as you had taken another bite out of the poor girl. You swallowed the red liquid before you had dragged her to a very secretive place that only you knew of.

When you arrived, the old, abandoned building was in front of you. Inside there were many chains -- this was where you took your victims. You had to keep them alive for the sake of living, as if you fed on them when they were dead, the blood would kill you.

You had tied the girl up to a pole, her eyes closed. She had passed out from blood loss. You looked at the bites you had left behind and smiled at your work.

Please no one find this, you thought silently to yourself. There was no point in telling anyone, as your friends, Sam and Dean, would not be pleased with your most recent activity of killing an innocent girl.

-Next Day-

You awoke in your room that you happily shared with your boyfriend of three years, Dean. You remember last night and turn away from his sleeping, peaceful face. You close your eyes for a moment.

After a few minutes, you finally started getting yourself ready for the day. You fix your hair and put on your normal, everyday attire.

Sam and Dean woke up not long after, and you had already left to check on the girl you feasted on last night.

The creaky wooden door had opened by your force and you had found her squirming. You swallowed and then smiled slightly. "Shh," you said softly.

She continued to squirm. You had ripped the rag out of her mouth that muffled her screams, tears staining her cheeks.

"What is your name?" You asked.

"M-Madison. Madison Quakes." She replies and stutters, fear in her eyes.

"Listen, if you want to live, you have to be quiet Madison." You smirked devilishly. She nodded slowly and gulped as she heaved.

With quick movement, you had exposed the inside of her arm by extending it outwards. You took a bite out of her wrist, and she screamed. You swiftly pull away.

"I thought I said to be quiet!" You yell before snapping her neck. You looked to your right to see a shattered mirror, blood staining your teeth and around your mouth. You sighed softly and took an old cloth and cleaned yourself up, as if nothing ever happened.

You had stopped by the local cafe to get some breakfast for yourself and the boys. You got pancakes, bacon, strawberries, and of course what you wished to have which was simply some pancakes with some strawberries. That girl really took the hunger right out of you.

You had walked back to the motel and knocked on the door, as your hands were full. You sighed softly and heard the footsteps behind, only to see Dean open it with a warm smile. "Ooo, what'd ya get?" He asked like a little kid.

You chuckled softly, "pancakes, bacon, and strawberries for you two." You reply and set it down on the small table that was provided. On each side there was a comforted seat, which Sam sat in one and he looked up from the laptop. You had gotten a glimpse of the tabs he had open. One was some sort of article, and you couldn't read the heading as he shut it too quickly. You shook your head, you were worrying to much.

"Thanks, Y/N." Sam said politely and began eating. Dean sat down across from his brother and you hand him the box that was filled with his food. You have him a quick peck on the lips before eating yourself.

The small TV in the corner had been playing... on the news.

"Twenty-three year old Madison Quakes has been found dead in an old, abandoned building. Her body was found in this building behind me with many bite marks on her neck and on her forearm. This is still a developing story." The reporter said. Behind her was the police with the crime scene tape around the area to keep certain people away from it, such as the citizens on the town.

You weren't sure how they had found it.

God is not on my side, is he? you asked yourself before sighing softly. You looked at Sam and Dean who ate rather quickly, eager to leave and investigate.

"Where is it at again?" You question, turning to the boys.

"We will find it, come on." Dean said.

"I'm fine," you said rather bluntly.

"Your loss," you hear Dean mutter as Sam follows him out the door, shutting it closed behind himself. You then hear the Impala start and the boys drive away.

"For fucks sake," you mutter softly to yourself.

It had been at least three hours before the boys returned. Usually they were gone for about the rest of the day to go into a deep investigation and find what killed who or what, but this afternoon was different.

"Y/N!" You hear Dean yell as he opens the door to see you sitting on the bed.

You sat in silence before looking up.

"What did you do?!" He exclaimed. Sam stood behind him.

"I'm sorry, okay!" You yell back. "Do you think that I ever wanted this to happen? Do you think that I ever wanted to be something that you hunt? You should be happy that I don't kill someone every night and lie to you!" You yell back as you stand, Dean towering over you.

"How come you didn't tell us the moment it happened? A poor teenager girl just died because of something that is allegedly not real!" Dean yells back, throwing his hands up in the air.

"If you were one, you would understand. But you obviously don't, so why even bother? It's not like there's a lot of vamps out there who don't always feed on humans, so please, be my guest to let me go." You said more calmly. You clenched your fists.

"That's not what I meant," Dean said as he collected himself.

"Then what do you mean?" You quickly questioned back.

The night was cool. There were way too many victims to pick from, so you simply took one and made the young man your snack.

"Y/N!" You hear a familiar voice say. You drop the now limp body of the young man's and turn to your boyfriend. Blood was surrounding your mouth.

"I'm sorry," you chocked. You slowly backed away and looked down at your hands, simply to see blood smeared across them from the victim. Dean rushed over to you and embraced you, tears streaming down your face. You were repeatedly apologizing to him about killing an innocent man.

"Shhhh," Dean shushed you gently, caressing your skin. He placed a loving kiss on your forehead and embraced you once more.

"I won't do it again, I promise," you said as you were climbing into the Impala, Sam sitting up front. You had informed him of everything. Well, more like Dean actually had.

"If you were in my shoes, then you'd understand." You said before you had grabbed your f/c jacket and pushed passed the boys, walking out the motel door.
