Stalker!Reader meets Dean Winchester and falls in love.

This bar is one of the noisiest we've been in a while. The fraternity jocks appear to be celebrating some sort of championship. The smell of alcohol penetrates the air, and the cheerleaders in miniskirts scream inconsistencies loudly. It's been 30 minutes since we've entered, and I already want to leave. Sadly, the decision is not up to me. As I raise my gaze I see Dean Winchester flirting with a busty blonde, I suppress a groan. Here we go again. We've been in this town for a week, and he has already slept with two whores. He's on a spree. Which is not good for me, I really don't like doing what I do, but he keeps pushing me to it. Can't he just... keep it in his pants? Like Sam, Sam only sleeps around once or twice a month. It'd be so much easier if I had fallen for him. Still, Dean being him is what made me love him. Even with his womanizer attitude.

"... should ask the college professor about th..." Sam is saying, but in spite of it, Dean keeps staring as the blonde retreats.

I stab my pie to control the urge to smack her face into the table. He should be with me. She's just a lowly-paid waitress who can't even differentiate between a Magnum and a Compact. I breathe in, it's fine. She is just a distraction for him, just like all the ones before her. She is nothing. I shouldn't get worked up about a bug like that. It's not worth it. Instead, I should wait and measure my time. I should wait for the right moment to make my move.

I've been following the Winchester brothers for about three months now. And even before then, I kept track of Dean for two months. I know his patterns, and I know just popping out of nowhere will only cause mistrust on his part. No, I need him to trust me. I need to be eased up into his life smoothly. That way he'll know I'm the right for him. Not those busty whores he likes to sleep with, me. Just me and my hunter.

The first time I was interested in Dean Winchester, it was through Bobby. The old man and I weren't friends per se, but he had helped me before doing research. That day I was at his house when he commented about the Winchester brothers. So far, I had only heard a few rumors about them. That the youngest was a half-demon, that their father made a deal with a demon, that the eldest went to hell. I didn't pay attention to any of it. Not until Bobby told me more about them. What he said wasn't that much of a big deal, really. He mentioned that they had been raised in the life since kids. That had piked my curiosity because I had been also raised to be a hunter since I was a baby. That small interest escalated when I encountered them in a hunt. They were already leaving, they had just finished with it, so they didn't notice me. They didn't notice as I saw them decapitate a nest of vampires. They had it handled, so I stayed in the shadows and watched.

From then on, I started to inquire about them. More specifically, about Dean. And the more I found out, from other hunters or other monsters, the more fascinated I was. Then I found the Supernatural books by Carver Edlund. They were a great source of information, but they also made my love for Dean... shift. It became stronger. The need to protect him was so overwhelming that I had to know what he was currently up to. That's when I started to... take care of him. I would clean up his messes and direct him to the right path. I'm good at doing it. So far, neither of them suspect that it's me who points them to the right hunt. Or that helps them fight the monsters. Or more importantly, that gets rid of the nasty bitches who think themselves worthy enough for Dean. Killing them without the brothers noticing is enough trouble as it is. However, hiding the body, as an experienced hunter, comes easy. The worse part is that I have the police on my trail, they haven't connected the women to me or Dean, but I have to be more careful from now on. It doesn't matter, really, I'm doing this for him. I cannot take credit for all of it, but that's alright. As long as Dean is happy, I am... What the fuck is he doing?

The busty blond has suddenly been replaced by a tall brunette. She is flirting with him while he is at the bar alone. Where the fuck is Sam? I glance back at their table and find that the youngest brother is packing his stuff. For the looks of it, he has left Dean to his conquest. Fucking annoying. I haven't done anything to Sam because he is useful. He keeps Dean in check, mostly. Not that I don't think their relationship is toxic as fuck. If Dean weren't so fond of him, I might've already gotten rid of Sam. Nevertheless, while I'm not with Dean, Sam is my best bet to keep him safe. After all, I can't be with him all the time. Still, right now, Sam is really pissing me off. Why is he leaving Dean with that monster? And this is not some stupid jealousy, all the clues are there, they just can't see it yet. I cracked this case yesterday. The siren they're hunting is... WALKING AWAY WITH MY HUNTER! Son of a bitch.

I look back at Sam's table to find that he's not there anymore, and Dean is leaving. Crap. I quickly take my things and place some money on the table. By the time that I rush out, the Impala has already left the lot. I hop into my car and turn on the tracking device I have on Dean's car. To my greatest horror, he's going in the opposite direction of the motel. It seems that he's taking the monster home. It would've been better if they had gone to the motel. Fucking Sam. Why couldn't he solve the case sooner? The Impala stops and I accelerate. Why is this happening to me? Why did he have to sleep around tonight? No matter, when the right time comes, I'll show Dean that he deserves more than that.

By the time that I make it to the address, the lights are already off. The Impala is just right outside and my heart pounds rapidly. What do I do? I can't just go inside, and I can't call Sam either. So far, I haven't had a situation like this. A situation that would push me to show myself. And it's not time to do so, either. I have a plan, a plan that will make Dean fall for me, trust me, a plan that will show him I'm the right for him. And this isn't it!

Unfortunately, when I hear a loud crash coming from inside, that plan goes to shit. I climb out of the car faster than ever and run to the door. Luckily for me, it's open. There's no one in the living room, so I have to climb up the stairs. I enter the master bedroom, and suddenly I don't regret going in. Dean is lying on the floor unconscious, above him, the siren is holding a knife. The creature notices me immediately, which is good, considering that it leaves Dean alone. I pull out the bronze dagger from my pocket as the creature launches at me. It pushes me to the wall, trying to knock me off balance. I place my hands on its shoulders. The struggle doesn't last long. At the first opportunity, I stab the monster in the heart. It dies instantly. I exhale, I'm on a time limit here, I need to get out before Dean...

"Who are you?"

Well, fuck.
