Title: All Good Things Must End

Rating: NC-17 (language, m/m sex, violence)

Note: Can't all be sex, sex, sunshine and rainbows. The boys split and will take a bit to reconnect.

The wendigo attack had changed the relationship between Sam and Dean, and not for the better. Sam was one possessive motherfucker and it was wearing Dean's nerves thin. He tried to understand his lover's possessiveness but that was one thing Dean Colt would never understand. Of course he felt possessive toward Sam, and the Impala but Sam was different – scary different when it came to Dean. Dean had no family other than his father who he didn't really remember. All he remembered was the brutal training. His father could have cared less about him, and definitely wasn't possessive of him. A burden was what Dean was to his father, at least that was what he remembered thinking. No one had ever shown Dean the kindness that Sam had and it hurt Dean to the core that Sam was pissing it away with how he was acting. Dean could take care of himself, even among demons – he had learned everything he needed to from Sam. But Sam had other ideas and it was getting out of hand, too much controlling of Dean's life for his liking. And the sex? It had gone from being as gentle as two passion consumed over-grow adult men could be with each other on a daily basis to this…Sam quickly fucking him into oblivion, no prep, no intimacy, just raw fucking. Then Dean would feel Sam using his powers to knock him out, and then leaving for the night.

"FUCK SAMMY!"He screamed through clenched teeth as Sam thrust into him one final time before he was cumming inside him!

Sam pulled out and immediately went down on Dean's dick causing him to explode in his mouth.

"My god Dean," Sam said after he had swallowed Dean down. "So needed that." He collapsed onto Dean's chest with his hands stroking through Dean's hair.

Dean wrapped his arms tightly around Sam. He wasn't leaving him tonight, not tonight. He had questions he wanted answered…but he was getting so sleepy. Dean knew he would wake up a few hours later to an empty bed, no clue where Sam was or what he was doing. The next morning his lover would come back looking like hell warmed over with dark circles under his eyes, gaunt expression, and often covered in blood – but never his own. If questioned he would clam up and they would spend the next few days not talking and not fucking each other's brains out. Dean didn't know how much more he could take before he bailed. But the final straw was coming quickly and right before Christmas all hell broke loose and Dean found himself running for his life!

Sam knew what he was doing was wrong, that he had gone far off the reservation now but he was consumed with revenge. Yes Dean had survived the attack. Yes he had used his powers to rescue his beloved. No, he still couldn't let Dean know the full extent of what he could do – the older man would run away. But he had a darkness inside of him and it was yearning to be free. He knew he was often neglecting Dean to go out and try to hunt down the bastards responsible for trying to hurt Dean and start the Apocalypse early. Allistair and Crowley were working with a few others to capture Dean, drag him into hell and torture him. They knew Sam would quickly spiral downward without Dean and assume his role, if nothing else just to get to Dean, to protect him from those that wanted to hurt him. He would not let that happen and if he had to neglect Dean for a while until he could sort things out – well it wasn't ideal but it had to be done. Not that Dean needed Sam by his side 24/7, Dean was more than capable of handling himself – a fact that made Sam wonder just exactly Dean was. He had ruled out complete human shortly after the wendigo attack when he healed quickly. But Dean was asleep now and now he had to go and try to track down the bastards. He had to keep Dean safe.

Dean woke up and Sam was gone. He had had enough of his shit! He was gone! If Sam wanted him then he would find him, easily enough Dean figured. He packed his duffle and wrote Sam a quick note. Heading toward the Impala he saw Sam in the distance and quietly slipped up on him. What he witnessed horrified Dean!

Sam was hopped up on demon blood, had consumed large quantities if Dean had to guess. Why he had no idea but Sam wasn't his Sam – not anymore! Dean was becoming more and more empathetic to Sam's thoughts and feelings and the rage, and anger, and hatred was consuming his lover and by proxy him and Sam wasn't stopping it. Dean was getting sick feeling what Sam was feeling. It was vile and rotten, so nasty! It was getting too much for Dean to handle, and he could handle a fucking lot!

"Revenge, revenge, keep Dean safe, mine, kill them all" repeated in Sam's mind and echoed through Dean's. It seemed that Sam had a one track mind and it wasn't for Dean anymore, or hunting things and saving people. Sam Winchester was bent on revenge, consumed by it and losing his humanity more and more.

Sam saw Dean and sprinted away but Dean followed by following the trail of mangled demons. His lover was blazing through them like they were nothing. Finally he caught up to Sam who was grilling a demon for information about where Crowley and those siding with him were. Dean realized once again that Sam was no longer his Sam, that he had lost his humanity and had become something that he couldn't recognized. His world crashed down on him, the weight of losing the one thing that he had finally found love in overwhelmed him and he broke.

Dean was breaking, Sam could feel him breaking down. Shutting down, shutting him out but he couldn't stop. He was too powerful and almost had what he wanted. Then he could go back to Dean but Dean no longer wanted him! The darkness in Sam ignited, consuming whatever humanity he held onto. Without remorse, without thought, he directed some of the violence at Dean.

Sam had thrown him through a wall, clear through a fucking wall! Where the wood and plaster should have ripped his body apart Dean wasn't hurt. Not even a scratch He was groggy and having difficulty getting up but he was otherwise fine, which seemed to have pissed Sam off. He tried to get up but Sam was over him, pinning him down and brutally punching his face! Dean let him, he wasn't feeling a thing pain wise, but he was emotionally devastated inside. The rage and hate coming from Sam successfully managed to shut Dean's soul down. He felt nothing toward Sam now and only needed to get away…and somehow he did…though how and what happened he couldn't explain. The next thing he knew he was in the Impala and was hauling ass toward the state line.

Three hours later he pulled into a filling station. Dean didn't think Sam was following him, why would the son of a bitch? He had made it all to clear what he really thought about Dean – a demonic hell spawn's fuck toy and punching bag. But there were others that wanted to harm him, maybe. He didn't know if Sam's fall to the darkside would cause rejoicing among the demons and hell or if others wouldn't want a piece of him out of revenge. He was lucky he had learned everything about safeguarding against demons from Sam. Physically he would be ok, and mentally he would deal with the betrayal. Shove it down and lock it away, using it only when he needed the extra oomph it would bring when he needed to kill a poor bastard. He wasn't going to waste time on self-loathing or chick-flick moments blaming himself. The only thing that had been his fault was that he was stupid enough to fall for Sam's honeyed bullshit! Dean's fault, no one else, and Dean had dealt with it. He knew he couldn't destroy the anti-Christ but he now knew hunters who could at least help him try. Sammy had to be stopped, he was no longer human, no longer clinging to his humanity. Well he couldn't think about it now because he still wasn't far enough away from Sam to feel comfortable that he wouldn't come after him in vengeance – and that was exactly the time the Impala sputtered and came to a dead stop in the middle of the dirtroad in the middle of nowhere. Stopping inches from a little blond girl wearing a white dress.

Sam woke up with one hell of a headache and no idea where he was, how he got to the warehouse, why there were so many bodies around him, or where Dean was!

"Dean!" He screamed as he got up feeling like he had been hit with a bus. There was no answer and his heart pounded with fear. Something bad had happened and Dean was in the middle of it, that much he remembered.

"DEAN!" But there was no answer. Sam panicked! He had to find Dean, had to – Crowley was close by now he could feel him, and he wanted to hand Dean to Allistair and Sam couldn't allow that. He had to find Dean before Crowley did! Frantically searching through the rubble he stopped and stiffened when he felt Crowley's presence behind him.

"Well done Samuel," the demon commended him on something Sam had no idea about.

"Really thought it would take a little longer for you to turn darkside," the demon stopped in front of him and offered him a fake concerned look. "But," he continued. "Putting a hit out on your boyfriend made things happen so much quicker. You really have embraced your human side Sam. Loving someone, bringing him into the family so to speak. The look on his face when you slammed him through the wall was priceless. Oh, and beating him within an inch of his life – classic devil spawn Sam."

Crowley's words made Sam's blood run cold. He would NEVER hurt Dean. He loved the man, depended on him more than anything or anyone. Demons lied and Crowley was the king of lying.

"Bullshit," Sam said as he stood full height. He was ending Crowley's life tonight.

"Before you kill me Sam ask yourself. Where is he? Where is your hired gun, your soulmate, your lover in all things dark and supernatural?"

Sam's blood ran hot. "You don't have the balls to take him from me," he spat as he focused everything that made him embrace the dark on the demon in front of him.

"Well I have the equipment Samuel. But no, I didn't take him from you. You did that all on your own." With those words Crowley sent memories of the past few moments through Sam's mind.

Sam shuttered and fell to the ground grabbing his head in his hands. The pain was beyond anything he had ever experienced! Images of Dean in the hospital, demon blood orgies, torturing demons for information, being purposeful neglectful and hurtful to Dean, throwing him through the wall, hitting him, he had done all of that to the one man he loved more than life itself. To the one person who kept him human and now Dean was in Hell being tortured by Allistair while he was topside pretending to be human!

"See Sammy, that was his pet name for you wasn't it? You did it. Dean suffers on Allistair's rack because of you. You can get him, set him free, rule with him in Hell – if he even wants you now, which I doubt he would."

Sam knew demons lied but he also knew he had done those things to Dean and that Dean wasn't the type to forgive. His mind was lost in grief. He had lost Dean forever and the only thing he could do was to get his ex-lover off the rack and let him be – in Hell. He was broken now, just like those opposed to him and his Father wanted him. Didn't matter what happened to him, he would get Dean off the rack.

"Don't hurt him please," Sam begged. "I'll do it. Whatever you want. Just take me to him please!" Sam was groveling at Crowley's feet.

"Very well Sammy boy," the demon said as he placed a hand on Sam's bowed head.

But before the deal could be sealed a white light filled the room.

A moment later Sam was looking up at blue sky and an unfamiliar face staring down at him. And the only thing Sam noticed was the emerald green eyes, the same shade as Dean's. But the creature looking down at him wasn't Dean, though there was a resemblance...and it was definitely a creature.
