Spawned by prompt #4 for the
Demon Jesus 100 flash-fanworks-a-thon: "For now we see through a glass, darkly." Yeah, I've totally given up on bothering to claim things. Shut up.
So, hey, look, Dean's not an idiot; he knows how these things work. Wacky alternate universe and goatees mean wacky alternate evil. He's not an idiot; he knows which side to take.
It's just that, well, Sam being possibly evil has never stopped him looking out for his little brother before and doesn't seem to be stopping him now.
"Thanks for the quickdraw, bro," says Evil Sam, looking him up and down. "And, I'm going to guess you're not from around here."
"Yeah, I'm pretty sure I'm not in Kansas anymore." Dean eyes the people Sam had just flung against a wall with the power of his mind. "Dude, not bad for a complete dork. Tell me I am a complete badass in this world."
Sam raises one eyebrow, gives him that trademark little-brat smirk, and Dean feels his stomach sinking a little.
"I'm totally your bitch, aren't I?" he says, and doesn't need an answer.
What he's expecting next is, well, something horrible, but what evil-goatee-Sam does is lock up the attack party, switch on the game, and crack open a couple of beers for them. And okay, when Sam kicks off his shoes and lets his feet air out, that's pretty fucking horrible, but not quite the same kind.
Dean's about to say something, because fuck if he's gonna ruin a good reputation of never being able to keep his mouth shut--and Sam looks over at him, "What, you'd rather I put you on the ground and used you as a footstool?"
"Uh, no, this is good," Dean says quickly, and then because it's still kinda Sam; "any closer to those stinkers of yours and I think I'll pass out."
Sam slouches down in the sofa a little, knees sprawling, one knocking against Dean's as if to catch his attention. "So, you wanna have sex?"
Dean coughs a little, because he'd still kinda been hoping he was wrong about that. "Uh, you're my brother, and possibly evil, and also not a chick, so I think I'll pass on that."
"Fair enough," Sam says easily; shoots him a sidelong smirk. "Want to have sex with a chick while I watch?"
"Dude," Dean starts to protest, then stops and considers it. "Yeah, okay. Is she hot?"
It turns out, she's totally smoking, so Dean pulls out all the stops. Goes down, does the tongue thing and the other tongue thing and five different things with his fingers. Gets her dripping wet and whimpering, rolls in a condom and sinks right in. Damn, but she's hot, wrapped all wet and tight around him, little squeezes of her pussy that make him moan as he thrusts. And, okay, it's kinda weird that his brother's over there jerking off, and then it's even weirder when Sam crawls in close and trails his fingers up the girl's neck, up her cheek.
"Gorgeous like this," Sam mutters, and meets Dean's eyes, looking a little glazed. "I wanna--want to do her, come on, share--"
He hesitates, but the girl gives a throaty sob and, "Please, please yes--" and you don't say no to a lady when she asks nice, especially if what she's asking for is lots of sexing.
So they wind up--Dean pulls free for a minute and Sam gets in there, gets his cock all wet in her pussy--and they wind up Sam sliding into her ass and Dean burying himself back in her pussy and trying not to touch Sam more than he can help but he's getting laid so he can overlook a little weirdness. The hot chick's moaning constantly, all "oh, oh, oh," shaking between them all helpless and overwhelmed and it's really fucking hot.
Then somehow she's fingering him. It's surprisingly good, except every time she comes she scrapes him inside with her nails. So, Sam mutters, "let me," reaching around from behind the girl, and gets a couple of fingers in before Dean can remember to protest, and, okay, obviously this was a massive set-up from the get-go but he's starting to forget why it really matters.
Sam's fingers are sparking off something pretty good inside him, and he knows what Sam's gonna want next so just, the hell with it, go with the inevitable. "Okay," he gasps, and between Sam's teasing fingers and the girl's spicy skin, he's burning up with heat--"okay, do it," and Sam makes this hungry desperate noise that's just, it's fucking hilarious, is what it should be, but Dean flushes all over because it's directed at him and then Sam's holding him down, sliding into him thick and slick while the girl just sprawls on the ground and shakes, deep gasping breaths, completely out of it.
"Aah, Dean," Sam groans, low and helpless and this burning pressure filling Dean's ass, rubbing against a spot that feels like lightning. "Yeah."
And Dean pants back, "Yeah, yeah," and rocks back against every thrust, because it turns out Sam's cock in his ass feels kind of amazing, and he moans and moans 'til every nerve in his body goes up like a firework and he comes with a goddamn wail.
"Dean," Sam gasps again, and pins him to the floor with a hand on the back of his neck, and just pounds into him, over and over until he can hear his goddamn brother break and come to pieces, getting off on fucking him.
Well, oops.
That sort of sets the tone for the rest of it; days spent with Sam in geek mode, poring over ancient writings to try figure out how to set things right, get Dean back home. Nights spent with Sam pinning his wrists, mouth wet on his collarbone, on his throat, Sam's cock fucking into him until he can't remember where he is anymore, hands twisting in the sheets as he comes.
He did try to protest, the second time, and a little bit the third, but after that he stopped making Sam get the girl involved, because apparently he was just gonna give in anyway.
The evil thing comes up at one point; Dean brings up the Star Trek mirror universe and Sam claims it's the lack of goatee which is evil, which just, whatever you wanna do in this freaky universe is your call but messing with Dean's memories of motel sci-fi repeats? Not cool.
Sam, evil-goatee-Sam, is still working on the whole mirror universe problem when Dean's actual Sam shows up. It's actually pretty embarassing, because they're not technically working on the problem when Sam shows up; they're naked and Sam has Dean bent over the desk, face buried in the crook of his elbow, begging in a broken voice with his other hand on his cock.
Um. So, Sam, actual Sam, does kind of a nut at that; tackles Sam with a goatee to the ground, makes him swear not to, you know, force Dean or anything--
The Sam who's probably evil just rolls with it, taking all the heat, and the two geeks get distracted by quantum physics and shit, and later the Sam who's maybe evil looms over Dean's bed in the darkness and says in a voice filled with dirty amusement, "So, if I promise not to rape you, do you wanna have sex?"
Dean, God help him, totally does, which is why he's gripping the headboard within minutes, white-knuckled and panting, losing his fucking mind over the cock that's pounding into him hard and hot and fierce.
Afterwards Sam won't meet his eyes, which is odd; instead of being all cocky and smug Sam burrows into his shoulder and mumbles at him. "Stay here. You can both stay. Your brother lives and no one comes for your soul. Stay with me."
So, hey, look, Dean's not an idiot; he knows how these things work. "Where is he?" he says quietly, naked and sweaty and sticky with some weird-ass version of his brother sprawled over him. "Is he dead?"
A pause and Sam makes a strange choking noise, says "Yeah," but still won't meet Dean's eyes.
"Where is he?" Dean says again.
There's a long silence and then Sam burrows deeper into him, six foot a million of small, miserable little brother. "Like you said. I'm probably evil. Dean had to-- tried to--"
Dean thinks about trying to kill Sam, to save the world, and wants to throw up a little.
"Where is he?" he whispers.
"He--" Sam's lips press against his shoulder. "He's hunting me. If I ever see him again, he'll kill me."
Dean tries to breathe, suddenly dizzy. A world where--no. No. How could he? How could he do without Sam, be able to hurt Sam like that?
"Stay," Sam begs, warm and naked on him. "You live, your brother lives, everyone's happy. Stay."
Probably evil. Dean runs his hand up Sam's side, warm flesh and the slight hardness of ribs. "Yeah," he says. "Yeah, okay."
Sam shifts against him, clinging to him.
It's dark and he can't see the triumphant smirk Sam wears.
