Sam was having an erotic dream.

And the star of his dream was his brother.

Which even in his dream he was finding disconcerting.

And somehow more aroused than he had ever been in his life.

In his dream he had an orgasm that had him gasping for breath. He woke up gasping for breath. His heart was pounding, his entire body felt shaky and limp, he was panting to get air into his lungs, he felt shivery and ecstatic all at once.

And then he realised that it hadn't just been a dream. The fingers of both his hands were tangled in short, soft hair and his achingly hard cock was pulsing and emptying down his brother's throat. Right down Dean's throat where the whole entirety of his long length was buried, in the most amazing, moist heavenly warmth that he had ever felt in his life.

"Oh God!" It was all he could say. He couldn't believe what had just happened: he knew he should feel ashamed….disgusted…..but "Oh God!"

From beneath the covers he heard an anxious if somewhat muffled voice. "Is that okay? That's how my Sam loves to be woken in the morning, I'm sorry if you didn't like it."

"Oh my God, yes! Oh God! Fuck, yes!" His heart was still thumping so hard as if to escape his chest, but now he managed to get enough control over himself to tighten his hands into the hair and start to pull Dean away from his now limp cock and up to lie on top of him. The smaller man was hesitant, but obeyed, allowing himself to be held in Sam's arms but arching his back in order to be leant up on his elbows enough to look down at him.

"Are you sure you didn't mind? I was enjoying your scent when I got carried away. I didn't mean to upset you."

"Oh God, you didn't! I… You shouldn't have…. But thankyou! That was incredible!" And Sam was blushing, he could feel his face burning but Dean was just looking at him without….any lust at all. He was anxious that he had pleased Sam, and happy that he had, but the younger man could see that it had meant nothing to him personally as an intimate act. Nowhere near as much as it meant to Sam.

"You're welcome." And Dean settled so that his nose was again buried into the larger man's neck. They were silent for a long moment. "I can feel your heart: it's beating right through my body as well."

Sam nodded, and without realising adjusted his hands so he could stroke Dean's hair as he held him. "It's because you did….that! That was… You didn't have to, you shouldn't have, I mean, but….wow!" The older man snorted a little but relaxed fully in his arms, enjoying his touch and scent.

Sam hugged him tighter: it didn't even feel weird to. He knew it should, but somehow having his brother lying on top of him in this manner felt right. There was a long silence while he tried to forget that the other had just given him the best blowjob he had ever had, and tried not to immediately get hard in the hope of receiving another.

Eventually Sam managed to concentrate his thoughts onto both their main concern: "So, where do you think we should start today? City Hall or the museum? Find out more about the building and its origins? Or try and find out what the stone is?"

Dean considered. "The building exists in both our realities. If it were something to do with that, then it would have been you and my Sam taken as well. But it wasn't: it was just the two of us Deans! I touched the glowing stone, and you say he did as well. And it must have been exactly the same time in both of our dimensions. So it would be sensible to start with that. Was the other half of it still in the cellar? I was too freaked out yesterday to look."

"I don't know." Sam hadn't thought to search for it either. "You say it was originally twice the size of the piece you have, and it began to glow?"

"Yes. But you…I mean my Sam, he couldn't see it."

"Neither could I. I wondered what Dean was on about when he walked across to see what it was. I couldn't see anything at all. But you could. And he could. But now you've got half of whatever it was. So where's the rest? Does he have it? Have we got to get you somehow to put it together again through the dimension wall? Or is it in that building still…?

You're right, that's where we're going to start looking! And, if we can pick up the trail of the creature we were hunting in there as well, that would be useful as well."

He carefully slid out from beneath Dean and clambered clumsily out of the bed, his whole body still feeling shaky from the incredible act that had been used to wake him up. "Showers and breakfast. I'm sure Dean won't mind you borrowing any of his stuff, well, except the porn!"

He smiled as the other's eyebrows rose in confusion. "Do you have porn where you come from?"

"Oh yes." Disgust showed in Dean's eyes. "Unclaimed omegas of both genders, deliberately dosed up to keep them in permanent heat, ready to do anything just to try and ease the madness." He shuddered. "And your Dean enjoys people being treated like this?"

"No! Not like you just described! I…er…I'll show you his magazines. But the models in them are all willing….I…er…Let's go and get some coffee first!"

ooooooooooooxoooooooooooooo

Dean stirred. He had actually slept extremely well once he had got over the revulsion of being in bed with what was not only a man, but also one that was the image of his little brother. But the bed was soft and he was exhausted, or so he told himself. Whatever: he had managed to sleep, which at least was a win.

He yawned and tried to stretch, his eyes flying open as he realised that he was still being held tightly in a strong pair of arms. He was startled to immediately meet Sam's gentle eyes: the larger man was lying lazily watching him sleep. Dean felt himself instantly tense up but he tried to force himself to remain calm. "Enjoying the view?"

"Very much." The other wasn't in the least perturbed by his aggressiveness. "It is quite incredible that there could be another being as beautiful as my Dean, but here you are! We just have to keep you safe and swap you back: which I'll be honest, I have no idea where to start."

Dean grunted: "Start at the beginning. Have another look at that cellar; that building if we have to! Find out what it is, what it anyone else has gone missing from it. Any strange occurrences connected with it. Take it from there."

"It sounds like you have done this before."

"It's my job. What we do: Sam and me. Track down the weird and nasty, and stop them both. That's why we were in that cellar: we had chased a were into that building and were looking for it. Why were you there?"

Sam sighed. "It's part of the case I'm building up: the biggest of my career so far! We're going after a big mob boss: if we nail him, it will help me in my bid to be assistant D.A. Two of his… em…. competitors were found dead in that cellar. Brutally killed."

He released Dean and sat up, looking serious as well as sad. "I just wanted to check it out. Thought I might…well, I thought I might spot something the police missed. Dean, my Dean, didn't want to come with me: I meant it when I said it's not a safe world for omegas, he'd far rather be at home. But his sense of smell and his eyesight is amazing. Far better than mine. And he's smart, much smarter than he'll admit. I just wanted to see if he picked up on something."

His head drooped down, Dean could hear the sorrow in his voice. "I wish I hadn't made him come with me. Then this would never have happened."

Despite himself Dean also sat up on the bed behind him and put his hands up on the wide shoulders. "Hey, if there's one thing I am an expert in, it's wishing that things had never happened. And if there's one thing I know, is that it don't do squat! All you can do is deal, and try to do whatever it takes to put it right… We'll get your Dean back for you. I promised your kids I would!"He felt Sam snort a little and relax beneath his touch. "And I'm promising you as well: we'll put this right. We've just got to work out how."

Then Sam was reaching up to catch at his hands and pulling him forwards until Dean's chest was pressed close to his back. And Sam was kissing the knuckles on each of his hands gently. "Thanks, Dean."

With a genuine sigh he released the smaller man and stretched out his long arms and back. "Don't shower this morning: you need as much of my scent on you as you can. And I'm sure my Dean won't mind you borrowing his clothes. You're right: we start with that building. Just as soon as we've taken the children to school!"

ooooooooooooooxooooooooooooo

It had been a strange car journey back to Kansas City and late afternoon by the time they got there. The previous day, Dean, the new Dean, had huddled in the corner in the back of the car, scared of Sam and afraid of everything else as well. Now he sat up next to him, close enough to have his hand permanently glued to Sam's arm, which meant that Sam felt he should drive mostly with his left hand and try to ignore the temptation to simply hold his brother's hand.

And Dean was looking around at the outside world now, trying to make sense of it all. Especially the people. Sam was aware of his interest in everyone.

He had studied the other Dean's porn magazines while he was eating breakfast, which to Sam's surprise had consisted of the last two fresh oranges he had in the bunker and nothing else but a mug of strong black, unsweetened coffee: exactly the same way as his Dean drank it. And exactly the same as his Dean, he had turned up his nose when offered the concoction with teaspoons of sugar and cream that Sam drank. The similarities and differences were amazing.

But he had studied the magazines with interest. "So, your Dean? He only likes female forms? Or does he like males as well?"

Sam had nearly choked on his cereal, he was so amused. "No. He's strictly for the ladies! But they pose in those magazines willingly: they're not forced or drugged."

"Oh, I can see: they're all just female betas. No heat madness in any of these pages! That's good. Safer."

"Safer?"

"Much."

And that was all he would say on the matter. But Sam was aware of his bro...this Dean's hand gently touching the back of his denims as they climbed the short staircase to leave the bunker, and he was aware of the short, self-controlling deep breath taken as Dean exited out into the world beyond the steel door. And he was aware of Dean's hand creeping near enough to brush against his own as he had stood and looked around at the trees and the space, and the fresh air.

And now he sat and watched the people in the streets as they drove through Kansas City. Watched the workmen digging their great big holes in the ground, and the business men and women in suits hurrying to their last meetings of the day, and the policemen on patrol, and the mothers taking their children to the park or to pick their elder siblings up after school or daycare, and the old women pulling along their trolleys loaded with the cheapest cans of produce from the supermart, and the short-skirted, bare-legged hookers that were always around on a big city street, even in daylight albeit in the shadows.

"So do you think they also pose in Dean's magazines?" His hand tightened around Sam's arm as one looked as she might come over to the Impala.

Sam tried to ignore it and her, and willed the traffic lights to change. "Possibly. Anything to get money."

"And they are all female?"

Sam turned at the question in his voice and noticed who Dean was looking at now. Again he tried to control his amusement. "No… er. That's one a transvestite. A man who likes to dress as a woman."

"But he can't have children?"

"He can't conceive and give birth to one, no. No man here can."

"Then why…?"

He was answered with a big sigh: "I don't know."

Sam risked a glance at the heavily made-up, high-heeled man and gratefully pulled across the junction. "It's two more blocks. I'll get as close as I can to it, but I don't want to start attracting attention either. Whatever happened in that basement yesterday, I don't want any repeats with anyone else, so we might have to walk a little. Just stay close to me if we do, okay?"

"Okay."

But the alley looked clear enough as Sam drew up near some trashcans. He got out of his door and began to shut it, only to open it again in a hurry as Dean had slid across the seat and was following him out of the driver's side.

"What was wrong with your door?!"

But he sighed as he noticed Dean's face: it was as pale and anxious as it had been the day before. This Dean did not like being outside. Especially where there were a lot of people. And Sam couldn't help but wonder why. And hope with all his heart that his brother was alright.

"Come on. Not holding hands!" as the other reached instinctively.

Dean looked abashed: "I'm sorry," he whispered.

"Just...stay close to me."

Sam un-holstered his gun from the back of his jeans in case, picked the lock and in they went to the deserted empty building. Carefully he pushed the door to and stood reaching into his pocket for his flashlight. But to his surprise, Dean was already moving across the gloom of the ground floor without any hesitation, completely unhampered by the near darkness of the boarded up windows, the stone already held out expectantly in his hand, waiting for it to do something.

"Hey?" It was a question, rather than a shout. Then Sam again noticed Dean's eyes seem to glow as he turned in response: cat's eyes, wolves' eyes? Not human eyes. What else about him wasn't human?

"At least the building in this world doesn't stink of death! There's no one here: our scents from yesterday are still clear. Nobody else has been in since. The packing area was this way." And he was turning to lead the way.

"Yeah, okay." Sam put his gun away and hurried to follow, falling over an old bucket and a couple of fast-food containers as he did. The noise echoed loud in the vast empty space.

"You alright?" And Dean was somehow there helping him up, although he had been almost halfway across the room already. "Hold on to me."

And he led Sam through the ground floor to the door of the basement area, with Sam holding his arm for guidance through the almost complete gloom of the large area only occasionally dissected by a stray shaft of light managing to sneak through between the boards in the windows. It only took a few minutes before they were at the doorway that led down the steps.

Here Dean paused and inhaled only briefly before moving to descend. Sam's fingers tightened in their hold on him. "Careful. Let me go first in case."

"There's nobody down there, Sam."

"What if you're wrong?"

He felt abashed at the glare that the other gave him even in the near-darkness: it was an expression straight from his real brother's amazing repertoire and told him without the need for any words at all that he was a total moron for even daring to doubt him. The younger man sensibly decided to remain silent but alert, and followed Dean down the steps, feeling slightly silly for still needing his flashlight, as, even though the large lift-able door was still wide open from where Sam had left it, the cellar was hardly lit.

As his brother had told him, it was completely empty. Sam was stubborn enough not to want to make any comment about his correctness, and felt suitably irritated by the look of triumph that was directed his way. "Yeah, yeah. Well, that thing's not doing anything! Anything else worth us being here?"

Dean smirked but it faded a little as he also glanced at the stone still in his hand. Nothing. His disappointment showed in his drooping shoulders as he turned away. Sam itched to put his hands around them in consolement, but forced himself to watch his silhouette as he took a deep inhale and began to follow a slight scent.

Straight across to the dais that the other Dean had been stood on the previous day. But unlike the other Dean, this one simply jumped up onto the raised platform in one easy bound without the need for using the steps.

Sam's eyebrows rose and he silently padded across to measure the height of the platform against himself. It was higher than he stood by more than quite a few inches and, even though a little piece of his brain wondered how many workers had fallen from it during the last century or so of use, the majority of it focused to remind himself that he was not with a human, however like his brother it looked. But by now, this Dean was following a trail and had moved to open the small access door, ignoring the wide open space beside it.

"Your Dean stood here: his scent, although now well muted, is still recognisable in the room. And there was something else: something recent that has left its musk on this handle. But not a being of your species: I can smell beta! Definite beta!"

"We think it was a werewolf we were chasing. That's why we were here yesterday. There's been two brutal attacks, both fatal. But they were both in broad daylight, which is very un-were-like!"

"They do not like daylight?"

"They shouldn't be able to exist in daylight! Not in their monster form: it needs moonlight to bring that nastiness out."

"Our Lady Moon would never allow a monster to exist beneath her pure and blessed light: that is when we worship and give thanks for her sereneness. This is such a strange world."

Sam silently seconded the thought. He continued to watch until Dean actually headed through the door to the deserted courtyard outside and then hastened up the steps to join him. "Any ideas where it went after?"

Dean breathed in deeply and followed the last traces of the scent across to an old fire escape in one corner of the building. Sam glanced at it: the old wooden ladders were rotten and dangerous, the base had already mostly fallen apart from the creeping damp of the previous decades of winter after winter. He sighed: the trail had led nowhere useful.

Then to his amazement and consternation, Dean had once more, and again unnaturally impossible for a human, jumped straight up from where he had just been standing. He landed lightly and leapt again immediately, working his way upwards right over the mouldy, green, unusable even as firewood pieces until he had alighted on the slightly firmer, but still dangerous, level 'landing'section where the next set of steps ascended from and up from then in a zig-zagging effect to the top of the building.

"Dean!" he hissed in alarm, as his brother….being that looked like him, but soooo wasn't…. headed up the stairs without a backwards glance and an incredibly sure step on the slippery and slimy surface. He desperately looked round to try and get up to join him….what if the smaller man fell?...but there was no way that he could get up on to even the lowest section of the wooden steps without it collapsing into just so many large, rotten splinters. "Dean! Get here!"

But he was ignored as the other was already nearing the top storey of the old building and then to Sam's horror, he was jumping again, right from the top level of the fire escape and up on to the sloped roof of the old building where he disappeared completely from view. Sam swore: he didn't know whether to return into the building to try and find a way up inside, or just wait there in case.

For what, he didn't know.

To his own horror he felt almost like crying when there was a noise above and Dean was reappearing on the old steps, working his way back down them as sure-footed as he had ascended. To Sam it seemed to be an age before he was jumping down off the last section and was safely on the stone-paved ground once more, although the two of them had actually only been separated for a matter of minutes.

He grinned innocently at Sam, a relaxed smile that was quickly switched off when the younger man all but knocked him to the ground and straddled his legs with his own to hold him down while his large hands held the other's face in a tight grip. "What the hell were you thinking? What if you had fallen?"

"What are you talking about? I was fine. It's not that high. And I knew if a beta could get up there then I certainly could: I'm naturally much more agile."

"But what if you couldn't?"

"But of course I could…." And his words were cut off as Sam suddenly captured his mouth with his own, kissing him with a desperation that took them both by surprise.

He stared up at the younger man as Sam released his lips with a blush that turned his face almost scarlet."I'm sorry. I don't know why I did that. It's just I was so worried about you."

He couldn't bring himself to look at the other: what the hell was wrong was him? He had basically just kissed his brother! But then Dean leant forward and gently touched their lips together once more. "I'm sorry I worried you, Alpha. I didn't mean to. I was just following the scent of the betas."

"I…." Sam didn't know what to say for a moment. Then: "Betas? Plural?"

"Yes, the scent of one went up the steps, but at the top there were two distinct ones. The other must have been waiting there: its scent was definitely stronger at the edge of the roof where it had been stopped. They both led across to the adjoining building, but the trail had been diluted too much by the wind for me to follow much further."

"How much further did you follow? You didn't jump across to the next…?"

"It's not far, Sam. Hardly counts as a leap."

"Christ, Dean. What the…? How can you be so afraid of being where there are people and yet go jumping around buildings like that?" He was getting up and helping the other man up to his feet, trying to recover from his worry and his embarrassment.

But it was him holding tight to Dean's hand as they returned to the inside of the cellar.

There was nothing else of interest in the interior. Sam could see their previous day's footprints in the dust as well as the ones that they just made, as well as the clear area where whatever had happened had caused it to be all but blown away, but there was nothing of note in there.

Dean followed the real Dean's scent to the exact spot where he had vanished from and they both scoured every inch of the floor, Sam using the beam of his flashlight and Dean with his sharp eyesight, but to no avail.

There was no sign of the other half of the stone.
