A/N: Hello dear reader! My name is CosmicStarlight21 and this is my second FanFiction story that I'm currently writing. This is my first Supernatural fic so please take mercy on me if this story isn't good and I'm sorry if the characters seem awful and out of canon. I'll be more than happy if you have any suggestions or leave any constructive criticism. This story will be dark one-shots about Supernatural, I do plan on making a story full of fluffy one-shots for those who don't like dark fics or just wanting to read both kinds.

CHAPTER 1- The Boyking of Hell:

Summary- Dean thought Sam was dead, he saw him die right? But what Dean didn't know was that Sam was taken by Azazel and given a choice, have Dean killed and his soul taken to Hell or become the king of Hell and hold Dean' contract as his own. Sam chose to save Dean but with years gone by of trying to keep Dean away from the truth and away from the darkness Sam is consumed with, Sam can't take it anymore. Sam needs Dean and if Dean doesn't want to go with him well luckily Sam has an ace up his sleeve.

Warnings-Cursing, kidnapping, mentions of Wincest and violence.

Disclaimer- I do not own Supernatural or any of it's amazing characters. I also do not own the dialog I borrowed from the episode 'All Hell Breaks Loose Part 1.'

Sam's POV-

There's a full moon out tonight. The illuminating silver bullet high up in the sky is calling down to the monsters below to come out and show themselves...To come out and play. I've been tracking him for months, and tonight will be the night...Dean Winchester, a hunter, a killer, my brother, my prey. Tonight I will claim Dean as mine and he will remain that way for eternity. All kings need a consort, and Dean will be mine.

I can hear his heartbeat, he knows I'm close but not where. As long as I stay hidden in the darkness his weak human eyes will never see me until it's too late. I lick my lips in anticipation of what's about to come. Once I'm finished with Dean no one in Heaven or Hell will question who he belongs too, especially Dean himself. My poor brother, I know he wishes he could see me again but little does he know his greatest wish is about to be fulfilled.

I listen close as Dean's footsteps get farther and farther away and I leap down from the tree from which I was watching him from. It's time to start the chase...Get ready to say hello to the new Sammy, Dean.

Dean's POV- Five hours ago at Harvelle's Roadhouse, located in Central Nebraska.

How did I get this hunt so wrong. It was supposed to be a simple job, go in with William and take down a few ghosts. There wasn't any fucking ghosts after all, it was horde of demons! And Will, that poor son of a bitch he died saving me from being taken. I should've called Bobby, I should've know it was a trap. Damn demons have been after me for weeks, why the hell do they want me so badly? Is it because of yellow eyes? Is it because of the colt? As soon as I find that gun there will be Hell to pay, and yellow eyes will be gone once and for all and not able to hurt another family again. I will avenge Sam and our mother, I will finish what my dad started.

I feel a headache coming on feeling like the millionth time today and I sigh. Why can't things go back to the way they once was? Back to when Sam and I were hunting together with our dad. We weren't completely happy but at least the three of us were together and a family. Well as much of a family as we could be at least. But then Dad was taken away, sacrificing himself to save me. And Sam...If I could go back in time I would in a heartbeat to save him from that psychotic Jake. Seeing Sam like that, holding him during his last few moments of life. I was too late to save him, I'm so sorry Sammy...I wish I knew where yellow eyes took his body. It wasn't enough to have one of his 'special children' kill Sam but he had to take his body with him away from me?! I didn't have a chance to say goodbye to Sam, I didn't have a chance to try to trade my life for his. I grit my teeth together thinking of all the ways yellow eyes is going to suffer by my hands and I shake in anticipation by what my mind comes up with for my retribution.

"Dean? Hey Dean, do you want another shot of Fireball?" I looked up when I heard the soft voice and saw Jo looking down at me concerned, her forehead crinkled with worry for me.

I gave her a smile, trying and probably failing to look like I wasn't loosing my mind. "Sure Jo, thank you."

Jo opened her mouth to talk again, most likely give me a pep talk to tell me what happened with Will wasn't my fault, but she closed her mouth and I was thankful. Jo quickly handed over a shot glass reeking of the strong alcohol contained within it and she walked over to where her mom was watching us from by the front of the bar. I love Jo and Ellen but they know or should at least know it's my fault about Will. I'm the one who asked him for help with the case, I'm the reason his wife and children will never see him again. God, I need to drink more. I waste no time in washing down the shot of Whisky and welcome the scorching burning it leaves in my chest. I hear the bar door chime as it's opened but I don't bother to look behind me and see who it is.

My eyes start to blur and my head's still pounding but I need another shot or at least a can of beer. I shakily stand up from my bar stool to go to Jo and ask her if I can have another drink but she's gone and so is Ellen. Where did they go? Before I have the opportunity to look for them both I hear their screams. As I try to run towards their cries for help I'm ambushed from behind. Strong arms wrap around my torso and more arms wrap around my own arms and legs and drag me down to the hardwood floor. I let out a shout mixed with surprise and anger and then try my hardest to get out of the grips holding me down, but they're unrelenting and so damn strong. Seeing that my struggling has no effect I try to reach the knife I have strapped on my belt but someone viciously stomped down on my right hand and immediately my hand was flooded with pain.

"Son of a bitch!" I screamed out to my unknown attacker.

"Now Dean-o, is that any way to talk to a dear friend like me?" I don't even have to see him as he comes into view hovering over me to recognize his voice. It's Yellow Eyes. Yellow Eyes stares down at me with a smirk and my blood boils.

"Sorry about your hand buddy but I need to have a chat with you with no unpleasantness," Yellow Eyes says without a hint of remorse in his words.

I try to surge up to attack the Demon but Yellow Eye's crew still won't let go of me.

"Where's Jo and Ellen?!"

"My dear boy, how I wish you had been destined to be one of my special children. But oh well. Where do you think they are? You hunters thought this bar was a safe haven? It only took five of my guys to take down your little friends. But don't worry Dean, they're still alive but not for long."

"Let them go" I snarled. "This fight is between you and I, not them!"

Yellow Eyes bent down to where he was face to face with me and said, "You're so wrong Dean. Those pesky hunters touched what belongs to the Boyking. And let's just say the king of Hell doesn't like his property to be touched."

I freeze at the Demon's words. I heard that name before, Boyking. I heard rumors from hunters a couple of months after Sam died that a human was turned into the new king of hell, they called him the Boyking. I didn't believe the rumors, they can't be true.

Looking as defiant as I can I spit right in the Demon's face. In a very low voice I reply, "I don't care who this Boyking is. I don't care to know why he's so interested in me, if he's even real. And I don't care about anything else other than taking you out."

To my surprise the Demon didn't hit me or try to kill for what I just did. The Demon slowly got back back up and wiped my spit off his face with a hand. "You know what Dean? Right now I kinda wish Sam had chosen to let you die."

"What the Hell are you talking about?"

Yellow Eyes looked exasperated. "Sam never died you idiot! Why do you think all the Crossroads Demons turned you down when you offered yourself to Save Sam's life? You can't trade your soul for someone's who isn't dead"

"N-No you're lying! I saw Sam die!"

"Did you?" The Demon cocked an eyebrow. "Sam was nearly dead when I took his body away from you. I wanted to let you think he died so you wouldn't try to find him, it was kinda pointless though since you still tried. Anyways, I offered Sam a deal too great to refuse which was basically he becomes the king of Hell or you die Dean. It didn't take little Sammy that long to give in. And what can I say? Sam was always filled with darkness but by becoming the king of Hell, he's ruthless now." Yellow Eyes chuckled and the Demons holding me also laughed.

"You're wrong. Sam would never be that selfish. Even with what we shared between us Sam would never be so stupid to make a deal with you!"

Yellows eyes stopped laughing and looked at me stunned. "You're joking right? I can't argue with you anymore kiddo. I'm here on business to deliver a message to you from the king. Sammy said to tell you he's coming for you at midnight. He said to say that you better be a good boy and not fight with him and he'll spare your companions but if not...Let's just say I personally hope you'll put up a fight Dean. I mean don't get me wrong Sam will get you in the end but to see you suffer by losing some friends that'll be perfect revenge for you exercising my children ."

"Fuck you! Sam's dead. Tell whoever your king is if he wants me to come and get me!"

Yellow Eyes just gave me a parting smile and with a wave of his hands both he and the Demons who had held me down were gone. I sat up and climbed back to my feet. That bastard! He's lying, he has to be! Sam wouldn't...I think he wouldn't...No, Sam's dead and I won't let Yellow Eyes tarnish his image by believing his lies. But I do believe there is a threat coming for me and I must get ready.

Sam's POV- One year ago in Cold Oak located in South Dakota.

{"I think we can make it out of here now," I say as we are leaving the Ramshackle house walking down it's short length of porch steps.

"But the Achiri Demon," Jake started to say with his voice sounding nervious.

I quickly interrupted him. "No, no. no, Ava was summoning it, controlling it. It shouldn't come back now that she's dead. We got to go."

I try to walk faster, and I can't help but wonder if Dean figured out where we were thanks to Andy yet or if he'll figure it out soon. I'm brought back to a start when Jake says "No. Not 'We' Sam." I turn to look at him feeling confused. What does he mean? We're both leaving now.

Jake continued and answered my unspoken question. "Only one of us is getting out of here. I'm sorry. That Yellow-Eyed Demon or whatever it was, he talked to me. He told me how it was."

I shook my head in disbelief and tried to plead with him. "No, Jake, listen. You can't listen to him."

"Sam! He's not letting us go. Only one. Now, we don't play along, he'll kill us both. Now, I-I like you, man. I do, but do the math here. What good's it do for both of us to die? Now, I can get out of here. I get close to the Demon, I can kill the bastard."

No, what the hell is Jake thinking?! We can both get out here, we can both go home to our families. I need to make it back to Dean..."Come with me, we can kill him together." I beg him.

Panic flashed in Jake's eyes. "How do I know you won't turn on me?" He asked.

I shook my head again and boldly stated I wouldn't do that to him. I would never turn on anybody.

"I don't know that." Seeing his mistrust I held my hands up then lowered my left hand to use to grab the knife that was in my pocket. Then carefully, making sure he was watching me I slowly placed it on the ground. I brought myself back up and calmly requested that Jake come with me, to not play into what the Demon wants. It seemed to work and Jake reluctantly took his iron rod and put it on the ground next to my knife.

"Okay," I sighed in relief. Then out of nowhere Jake punched me and I was flying briefly in the air. I felt my body take out a few boards from a wooden fence and then I hit the ground hard. Damn, Jake can pack quite a punch. Dazed I could only watch as Jake went through the wooden fence to come and get me, to come and finish me off. When Jake got close enough I kicked out at him and connected with his leg. I quickly stood up and started fighting for my life. We each got a few blows in but then suddenly there was a loud crunching sound and immense pain when Jake gave a powerful blow to my left shoulder. I grunted heavily from the pain and my adrenaline allowed me to continue to fight Jake despite my injury. The fight was over soon when I sent Jake crashing into what was left of the wooden fence and he landed on the ground. Grabbing my hurt shoulder I walked past where Jake was getting up and I grabbed the iron rod from where Jake had put it, and before Jake could attack again I turned and struck his face as hard as I could with the weapon. Jake fell to back to the ground but this time unconscious.

That asshole! He could've walked away, he could've came with me! I wasn't going to hurt him. I should kill him for what he tried to do. I even lift my arm holding the iron rod prepared to deliver the final blow but then I lower my arm back down and throw the rod away from me in disgust. I can't kill Jake, that's not who I am. I can't kill humans even the murderous ones.

"Sam!" I heard Dean shout. Dean! He found me. I run to where the direction of the shout came from and I can't help but to feel happy despite what had just happened with Jake. I stop running when I see him. Dean's here and with Bobby. The vision I saw a week ago, I'm past the danger now, it won't come true.

"Dean," I say felling a smile stretch across my face. My brother mimics my smile but then it drops and he's screaming for me to look out but it's too late. I feel something pierce my back and I fall to my knees as Dean shouts, "No!" Then Dean's there holding on to me to keep me from falling back and I can hear him talking to me but I can't say anything back. Dean's growing more panicked, saying more things but I can feel myself slipping away. I don't know if Dean heard me but as I felt myself go I said, "I love you Dean."}

Amazingly when I wake up I feel no pain. I'm not dead though or if I am I'm in hell because I'm back at my old family's house and the yellow eyed Demon is watching me.

"Hello again Sam. Did ya miss me? Jake sure did a number on you but lucky for you you're my golden boy Sam. Out of all my children you're the most special of them."

"What do you want from me?" I yelled at him.

Yellow Eyes pretended to look offended. "Tisk, tisk, Sam. You need to calm down. I just saved you after all and I have a deal for you. You should thank me."

"I'll never thank you! You murdered my mother! You almost killed Dean! You took my father! You've been watching me, you took me to Cold Oak, I was almost killed because of you!" I felt my throat starting to feel raw from my screaming but I didn't care. This monster has messed my life up and is still trying to. I won't let him take away someone else I love.

"Sam, if you don't behave I'll let Dean die."

Dean? He's going to go after Dean? "Don't you dare touch him!" I walked over to where Yellow Yes was standing at, which once was used to be my crib and I prepared to punch him.

"I won't touch him slugger, he's all yours. I know what you guys have been up too. But Dean will kill himself for you. I bet he's already on his way to find a crossroads Demon to trade his life for yours."

My jaw dropped. No, Dean can't do that. I rather actually die than lose him. "What are talking about? I'm not dead. He can't trade himself for someone who's alive!"

The Demon nodded. "You're right Sam. But you're in a dream right now. You're actual body is with me in Hell and you are dying but I can heal you. You've had the vision haven't you? The one where you're dead and Dean switches his life for yours? And instead of ten years Dean's taken instantly. Did you believe your vision wouldn't come true? Because it is Sam, and if you don't hurry and make a choice now that vision will come true and you'll lose Dean forever."

"What choice?"

The Demon grinned and my heart fell. "It's real easy. Either I'll keep you here while Dean goes and makes the deal and he's taken to Hell...Or I heal you now and you start the progress to become the new king of Hell and Dean is saved. It's as easy as that."

"You're insane," I sputtered. "Become the king of hell? What makes you think I won't turn on you if I give in and Dean becomes safe?"

The Demon almost looked bored by my question. "It's simple Sam. Once you agree to become the king the initiation process starts immediately and your gold heart will turn black as mine. You'll lose the person you are now and become something greater. You'll become someone worthy to lead us."

"I can't do that. I can't lose myself."

"Can you lose Dean," The Demon rebuffed.

"Give me a second to think," I hissed at him. My parents would not have wanted me to become evil. They wanted me to be good. If I give into Yellow Eyes I'm going to lose the best part of myself...But if I don't Dean will be taken away from me and I don't think I'd ever be able to get him back. I love Dean too much, I can't lose him. Even though it's a choice it doesn't really feel much like one.

Knowing my mind was made up I told the Demon what it was waiting for. "I'll do it. I'll become your king."

Dean's POV- Three hours ago at Singer salvage yard Location: Sioux Falls, South Dakota.

Before I know what was happening, I was being hugged. "Damn it boy! You could've been killed! Stupid Idjit, you should've called me the second after it happened not an hour later!"

I was released from the hug and I smiled. "It's good to see you too Bobby."

The elder man glared but I could tell he was happy and relived to see me.

"I'm sorry I waited to call you. I was checking up on the rumors about the Boyking." I try not to scoff at my words.

Bobby huffed. "The Boyking's a myth. No mater what that Demon told you the Boyking's not real. And about Sam, we saw him being stabbed. And I miss Sam, I really do, he was like a son to me as much as you are. But he can't be alive, not with a wound like he had."

I nodded in agreement. "You're right about Sam, Bobby. But I can feel it in my gut that Yellow Eyes was right about the king of Hell. I don't know who it is but they are coming for me."

Bobby stayed silent for a moment like he was trying to wrap his head around what I had said. "Dean if you're right then I'll protect you. And after that if this so called 'king' exists we'll take him out before he can take any innocent lives. If Hell has a king ruling it than all of mankind will suffer."

I agreed. "I know but first let's make a plan for tonight. If we are about to be facing off with the king of Hell we'll need all the weapons we got."

Bobby scratched his head in thought then looked at me and I could tell he had an idea. "Follow me," Bobby said. "I think we'll have everything we'll need in my panic room."

"You're what?"

Sam's POV-Now. Location the woods behind the Singer salvage yard.

There's a full moon out tonight. The illuminating silver bullet high up in the sky is calling down to the monsters below to come out and show themselves...To come out and play. I've been tracking him for months, and tonight will be the night...Dean Winchester, a hunter, a killer, my brother, my prey. Tonight I will claim Dean as mine and he will remain that way for eternity. All kings need a consort, and Dean will be mine.

I can hear his heartbeat, he knows I'm close but not where. As long as I stay hidden in the darkness his weak human eyes will never see me until it's too late. I lick my lips in anticipation of what's about to come. Once I'm finished with Dean no one in Heaven or Hell will question who he belongs too, especially Dean himself. My poor brother, I know he wishes he could see me again but little does he know his greatest wish is about to be fulfilled.

I listen close as Dean's footsteps get farther and farther away and I leap down from the tree from which I was perched on. It's time to start the chase...Get ready to say hello to the new Sammy Dean.

Azazel told me that Dean didn't believe him. Hell if the roles were reversed I wouldn't have believed Yellow Eyes either. Dean's sense of denial is stronger than mine when I was a human. My brother, still trying to believe the best about me. I thought I could escape Yellow Eye's deal and return to Dean with my morals intact. But Azazel showed me an amazing path, I cried the first time I killed a woman. The next one was easier and the next after that was a breeze. All the pesky human emotions that had weighed me down had vanished. I grew to crave more and more power, I craved killing. I tried to spare Dean by letting him think I was Dead. For months I ignored my need to find Dean and claim him. I focused on Hell and making it the way I wanted with more carnage and bloodshed. But after spending so much time away from Dean I knew I had to find him, to bring him to Hell with me and to rule alongside with me.

Dean will try to resist me, but the power will get to him like it did with me. He'll one day be happy to be in Hell with me.

"Bobby? Where are you?!" I hear Dean shout out. Ah, Bobby. he shouldn't have tried to shoot me. That was just rude, all it did was piss me off. I may have loved Bobby once like a second dad but that love ended when I was reborn, there's only room in what's left of my heart for Dean.

"No! Bobby, no!" I could hear Dean start to cry and my chest tightened. It looks like he found Bobby. The hunter had put up a good fight but in the end it was pointless, I had won. "Come out and face me coward!" Dean roared.

I walk over calmly to where I had left Bobby. Leaned up against a tree Bobby's head was slumped down and you could barley hear his raggedy breathing anymore. Blood dripped from Bobby's wounds from his stomach to the flowers below him like mock rainfall. Dean's back was to me and he was moving his hands all over Bobby trying to see where all he was damaged at. Dean quit looking though and turned to face me when I spoke. "Hello Dean."

Dean's beautiful green eyes were filled with sadness and anger but also acceptance. Dean finally knows he can't deny the truth anymore. I didn't die and I'm here and he knows I've changed. Dean stayed by Bobby's side but I saw him clench his fists.

"I didn't want to believe it. When that son of a bitch Demon said you were alive...I couldn't believe him. He said you were the king of Hell now but I thought to myself, no Sam wouldn't become that. Why? Tell me why?!"

I raised a brow. "You're asking me why I did it? Yellow Eyes told you Dean, I did it to save you. I love you Dean and I knew their was a good possibility I'd lose my humanity but I didn't care, as long as you were going to stay alive."

Dean's hands unclenched and he took a few steps towards me. "You asshole! You should've let me die then, because you're a monster now!" I hiss at Dean's words.

Dean's eyes widened in shock and he walked backwards, almost hitting Bobby in the process. "You-Your eyes...They're yellow!"

"Yeah, they get like that when I get angry," I replied with a dismissive wave of my hand.

"You're everything dad feared you'd become You're..." Dean's furious rant was cut off when Bobby gave a weak cough. Dean looked down at the injured man. "Bobby loved you! Why did you hurt him?!"

Someday in the future Dean will realize he doesn't need Bobby. Maybe I can try to make him understand now and save some time. "Dean, you don't need Bobby. Bobby only has another ten years left maybe less because he's a hunter. He won't be around forever and he's not our family. I know you think he is, I thought so too when I was human but I was wrong. All Bobby is, is just a meatsuit who provided us with hunts and weapons when we needed them. But we're done with hunting now Dean. You're coming with me and I'm going to keep you safe from the angels, safe from the real monsters, and safe from even yourself." I held out a hand to Dean. "Just come with me. Leave Bobby and come with me to where you belong."

Dean stared at me for a few minutes, looking unsure at what he had just heard. Once it seemed like Dean had soaked everything in he shook his head side to side.

"No, Sam. You're wrong. Bobby's a second dad to us, who's always been there for us not just when we wanted him but when we needed him. And I don't need protection, angels aren't real and I can take out any creature that we've hunted and more. I don't need to go anywhere." Dean pulled out a gun from behind him and lined it up in my direction. So Dean wants to play?

"Dean," I sighed. "You know guns won't kill me, they won't even hurt me. Bobby tried shooting me and it didn't turn out very well for him."

Dean ignored me and cocked the gun, preparing it to fire. Dean did take his eyes off me for a second though when Bobby coughed again and I had an idea.

I raised my hands up pretending to surrender. "You know Dean, I can save Bobby. Look at him he's dying." Dean trembled as he looked again at the quickly dying man. "Bobby doesn't have much longer and there's nothing you can do to save him but one thing. If you lay down the gun and come with me I'll heal Bobby and leave him alone. Bobby can have whatever remains as the rest of his life but only if you leave with me."

The gun in Dean's hands lowered and I knew I had Dean right where I wanted him. It looked like Bobby had regained consciousness sometime during my speech and he tried desperately to tell Dean not to do it but Dean put his gun down.

"Alright," Dean said. "I promise to go with you just heal him."

"Good choice Dean," I purred. I walked past Dean to where Bobby was trying to grab Dean's gun to try to shoot me agin. I kicked the gun away and knelt down and put my hands on both sides of Bobby's face. Concentrating I let my power flow from me to Bobby and with a white flash of light Bobby's wounds closed and he fell back unconscious. I stood up and Dean came over to check Bobby. Once Dean was satisfied with Bobby's condition he held still and waited as I came over to him. I grabbed Dean's hands an with defeated eyes Dean looked at me and said, "Do it."

Smiling at my victory I pulled Dean in close and whisked us away to our new home.

End A/N: So this is the end of this one-shot, I hope you guys liked it. I'm sorry it was kinda short. Would you like to see a part two to this? And I love Bobby by the way but I wanted to show how dark Sam had become and I was torn but I just couldn't kill off Bobby...at least not in this one. I don't know which Dark Sam idea I'll go with next but I'll try to upload as soon as I can. If anyone's confused the timeline is the same as the show except Dean and Saw fell into a relationship. A week before the events of the All Hell Breaks Loose story line Sam had a vision of Dean trading his life for his. And instead of the one year Dean got in the show he would've been taken to hell immediately. I hope that cleared up things. If you guys have any Dark or fluff story ideas please let me know and I'll try to make a one-shot using your ideas. Thank you all so much and have an excellent day!
