Summary
     It was just something all Alphas did. It was totally normal. And Dean
     didn’t like it one bit. Except for how he kind of did.
There were times when Dean wished Sam hadn’t grown up to be such a tall
motherfucker.  Like, any time they were walking side-by-side, or when Sam would
use his longer reach to hold things over Dean’s head, which, hey, that used to
be Dean’s trick, okay, it wasn’t cool having it turned back on him.  It was
fucking humiliating to be so much shorter than his seventeen-year-old baby
brother.  Then there were the times when they had to share a bed, even though
Dean was an adultnow.  The fucker took up all the space with his broad
shoulders and long limbs, which meant Dean had to sleep in a cramped up little
ball on the edge of the bed.
Yet, Dean never cursed Sam’s size as fervently as he did in moments like these.
“Say uncle, Dean,” Sam sing-songed in his ear.  The fucker was holding both
Dean’s arms behind his back and laying on his weight on them, so there was no
way for Dean to throw him off or roll them over.  His knees were positioned to
push Dean’s legs wide—vulnerable—and Dean could practically tastehow smug Sam
was about his little victory.  “C’mon, I’ve beat you fair and square.  Give.”
Dean huffed angrily, and the little puff of air blew some of the dirt on the
ground away from his face.  “Fair and square, yeah right.  I fucking sneezed.”
“Teaches you not to sneeze during a fight,” Sam said, in a bad imitation of
their dad’s gruff, no-nonsense voice.  “You have to be prepared for anything,
Dean.  You can’t have your body betray you like that—”
Sensing Sam was distracted with mocking their father, Dean heaved himself to
the side.  Sam swore as there was a brief struggle as Dean tried to get free
and Sam tried to roll him back into position.  Unfortunately for Dean, sheer
mass won out, and Sam slammed his face back into the dirt with a triumphant
grunt.
Fucking four inches and only god knew how many pounds made winning a hell of a
lot harder.
“Don’t make me grind your face into the ground,” Sam warned.  He sounded a
little bit exasperated, like Dean’s attempts to free himself were a minor
annoyance.  “You know the rules.  Give.”
Dean knew when he was beat, but that didn’t mean he had to be niceabout it. 
“Fine, you overgrown bitch, I give.  Uncle, okay?”
With an obnoxiously superior-sounding chuckle, Sam released his wrists and
leaned back a bit, letting Dean get his arms under him.  “You don’t have to
pretend, Dean.  I know you’re gagging for it.”
“In your dreams,” Dean shot back, the sort of thing any Alpha would say after
losing a tussle and having to play out the role that gave them.  His heart
fluttered a bit in his chest even as he said it, though, a neon signal that
Dean wasn’t being entirelyhonest.
He shouldn’t enjoy it, that was the thing.  Young Alphas all around the globe
fought and wrestled the way he and Sam just had—although with perhaps quite a
bit less training—all childish displays of dominance, a way to release
tension.  The winner’s prize was that whoever lost would get down on their
hands and knees and takeit.
Sam never protested it, probably because it was totally normal.  Alphas
couldn’t be with anyone else without risking getting them pregnant, given that
there weren’t any knot-proof condoms.  Some Alphas thought that the pull-out
method would work, but most people knew that once the knot started expanding,
there wasn’t any way a teenager would have the presence of mind to pull out
fast.
Instead, young Alphas practiced on each other.  Oftentimes, school locker rooms
after football games looked more like an orgy than anything else, the losers
letting the winners fuck them, loud Alpha growls resounding off the walls as
they began to learn exactly what being an Alphameant.
Dean had indulged in some of that stuff at school when he was younger.  He’d
liked it as both a sure-fire way to get some respect in a new area andan
opportunity to get laid.  He’d always loved watching that begrudging stretch of
back bow down in front of him as he thrust in and out with hard-won skill.  It
was almost as good as the way the Betas and Omegas would watch him afterwards,
the imagined stink of their arousal driving him to fuck his opponent even
faster.
The constant moving and his job taking care of Sammy meant that there wasn’t
much opportunity for it, however.  Sam, the little freak, didn’t like the idea
of doing it all with people he didn’t know.  “Dude, you never know when they
last showered,” he always said, face scrunched up in a moue of disgust.  “At
least I know you’reclean.”
Since Sam had turned sixteen, their evening wrestling had begun to end a bit
differently, and if Dean enjoyed it—the teeth on the back of his neck, the
weight of Sam in him, the hard press of him against what felt like every inch
of Dean’s skin—more than he ever had with any of the other Alphas he’d messed
around with?  Well, maybe it was just that he actually liked Sam as a person or
something.  How the fuck should he know?
Sam tapped his hip.  “Sweats,” he commanded.  “And shirt too, actually.”
“Seriously, man?” Dean grumbled, but began to strip obligingly.  He kept his
back to Sam, but he could feel his brother’s gaze on his skin as he pulled off
his clothing.  He didn’t actuallyobject, though, because the winner set the
rules and he’d made Sam strip before, to embarrass him or irritate him.  “I’m
gonna fucking burn.”  It was brightout.
Snorting, Sam shoved him back down onto his hands and yanked the sweats down to
his knees.  “I’ll be covering you,” he said, then lifted one of Dean’s legs to
pull the remaining fabric off.  “So you’ll be fine, princess.”
Dean kicked helpfully when Sam pulled the sweats off his other foot and smirked
when his heel accidentally connected with Sam’s shoulder.  The smirk
disappeared quickly when Sam slapped his ass in retaliation.  “Hey!” Dean
objected, twisting around to glare at his younger brother.  “The violence
portion of this evening is over, thank you very much!”
“You started it,” Sam said mulishly.  He was still fully dressed, but his
fingers were fiddling with the elastic band holding his sweats up.  He was
already so big, but Dean could see he was still growing.  The shirt he was
wearing, one they’d bought just a month or so before, was already straining at
the shoulders.  Sam, who’d always been so lean, was bulking up fast.  That
fucker.
“Whatever.”  Dean rolled his eyes and then rolled his shoulders back for good
measure.  “Let’s get on with it.  Hurry it up, Sammy.”
Sam sucked in a breath like he was about to say something, then seemed to think
the better of it and sighed.  There was some rustling, then the click of a
bottle cap opening and the wet sound of lube being squeezed out.
Sam let out a low moan and Dean sucked his bottom lip into his mouth.  He knew
what Sam was doing.  He could clearly envision the way Sam was slicking up his
cock with lube, stroking it from half-hard to fully erect, getting ready to
fuck Dean.  It was always a bit obscene when Sam jerked himself off, Dean
thought, and he’d seen it enough times over to the years to know.  Sam’s whole
body got into it, head thrown back, chest heaving, hips circling slowly…
If Sam had been an Omega, Dean would have thought it was hot as fuck.  As an
Alpha…
Well, he was an Alpha. Alphas just didn’t feelthat way about other Alphas—not
unless they were seriously fucked up—so it was just Sam.
Sam’s hands were slippery with lube when they down to grab Dean’s hips. 
“Spread your legs a little more,” Sam demanded, voice a little lower, a little
huskier.  Dean ground his teeth together, but obeyed, only growling when Sam
said, “good boy” in a sickly sweet voice.
“Dude, you don’t need to run your mouth to get off,” Dean said, and
automatically flinched when the head of Sam’s cock nudged up against his ass,
smearing lube in its wake.  As was their tradition, Dean—and Sam as well, he
assumed—had prepped minimally beforehand, so they didn’t have to waste their
time dealing with it once matters were settled.  “So why don’t you consider
shutting it?”
Laughing breathlessly, Sam pushed forward a little more.  There was a build-up
of pressure and then the tip of his cock was inside of Dean.  Nails biting into
the dirt, Dean tried not to make any sound as Sam’s dick pressed into him, inch
by inch.  This was yet one more example of why he hated Sam’s size.  Sam was
big all over.  Eight inches of big.
Dean’s ass was not built to handle eight inches.  The first time he’d fucking
cried—in a very manly way, of course.  Luckily, Sam hadn’t noticed—too busy
losing his virginity—or Dean would never have heard the end of it.
“Ugh, yeah, Dean,” Sam groaned as he bottomed out.  His fingers flexed around
Dean’s hips and he ground forward in an eager little movement.  “God, so
fucking tight.”
“And clean,” Dean quipped, trying not to sound like he was in an incredible
amount of pain.  He tried to focus on the dirt under his hands and knees, the
sweat gathering at the base of his spine, Sam’s harsh breaths—anything but the
hugecock in his ass.  “Showered for you and everything.”
“You’re a great brother, Dean,” Sam gasped out, sarcasm lacing his voice as he
pulled his hips back and snapped back in, jolting Dean’s whole body.  “Good to
know you only clean yourself for my sake.”
Sam fucked to his own rhythm.  Dean had been the one he’d perfected it on, so
Dean knew every move of it.  A few, he was pleased to say, Sam had picked up
from him.  The little swivel of his hips, for instance, that pressed his cock
right up against Dean’s prostate was something Dean was proud to say he’d
developed.  He’d always liked it best when the Alphas he’d fucked had
reluctantly gotten off.  With Sam, of course, it wasn’t nearly as vindictive. 
He’d never liked seeing Sam in pain, so after the first couple of times, he’d
gone out of his way to make getting fucked good for Sam and Sam had returned
the favor.
Nothing was as good as fucking Sam, obviously, but Dean had come to
occasionally—okay, more than occasionally—appreciate the way Sam thrust into
him, with one hard stroke, a shallow thrust, and then a slow roll.  As his body
adjusted once more to accommodating Sam in him, he began to involuntarily move
with Sam’s rhythm, his body encouraging his brother with quick little squeezes.
Fuck, he loved when Sam’s ass did that when he was in him.  The way it
fluttered around him, clung to him, clenched down on him as Sam came… Dean
liked the idea of giving that to Sam as well.  His brother should have
everything Dean could give him.  Every little piece.
“Dean, Dean, Dean,” Sam muttered, like it was some kind of religious chant that
would bring his orgasm sooner.  He moved, blanketing himself over Dean’s back
so he could bite down on the back of Dean’s neck, sucking and nipping at the
skin there.  All the Alpha in Dean made him want to throw Sam off, to growl and
snarl and thrash until the vulnerable back of his neck was released.  Even as
he shifted uneasily from the sensation, Sam’s hands tightened on him, holding
him still.  There was an urgency to it; Sam’s knot was beginning to expand,
rubbing teasingly at the rim of his ass with every move.  It was Dean’s
favorite part and he arched back into it, wishing it could go on forever.
God, he wanted to grab his dick and go to town, but any movement at this point
would just end in Sam pinning him down and growling, the Alpha part of his
brain seeing   it as an attempt to escape.  So he waited obligingly, panting a
little as Sam started to rut into him faster.  He was so fucking hard, if Sam
would just hurry up and finish—
“Dean!”  Sam hissed and Dean winced, both at the teeth biting into his shoulder
and the knot expanding as it pushed into place.  Sam growled incessantly as he
ground his hips into Dean’s ass, all hindbrain and none of Dean’s snarky little
brother left.  The man behind him was all Alpha, and Dean simply had to wait it
out.
Jizz was always the worst part of the whole thing, and Dean grimaced as Sam
cried out and came.  Sam’s come began to pulse into him and he fidgeted
uncomfortably.  While his ass certainly wasn’t made to take an eight inch dick,
that always seemed the lesser of two evils after Sam had pumped him full.
Sam didn’t seem to like the movement though, because his arms came down to hug
Dean around the waist, holding them firmly body-to-body.  “Ah, c’mon, Sam,”
Dean groaned, but he didn’t struggle as Sam rolled them onto their sides so
they were sprawled in the dirt.  Sam was still sucking on his skin contentedly,
so Dean sighed and waited for his little brother to come down from the high.
As soon as Sam’s mouth released his skin, Dean was reminded of the hard weight
of his dick.  He’d been content (okay, he’d been more than content) with the
fullness of Sam’s cock in him and the way his leisurely sucking had made his
chest feel a bit too warm.  Still, he wasn’t about to let Sam know that.  He
kicked his shin.  “Dude.  A little reciprocation, please?”
Still in caveman-mode, Sam only grunted, but his hand came down to hold Dean’s
cock, expertly squeezing and stroking it.  Dean relaxed, letting his head fall
backwards onto Sam’s shoulder as Sam pulled at his dick, relishing—even though
he knew he shouldn’t—the way Sam’s cock pulsed inside of him.  It was just too
much, Sam touching his cock and filling him, nuzzling into him like Dean was
his. He came quickly, with a low, muffled grunt, and Sam laid a light kiss on
the side of his neck.  “Dean,” he said contentedly, and nuzzled closer. 
“Dean,” he repeated.
“Yeah, yeah, I’m your favorite,” Dean agreed, yawning happily now that his dick
was no longer aching.  Sam continued to pepper his neck with little kisses and
Dean batted at him.  “Knock it off, dude.”
Sam pushed up on one elbow and hooked his chin over Dean’s shoulder so he could
look at him, pupils still blown wide from his orgasm.  Still, there was
something there, something heated and open that made Dean shift uncomfortably,
even though Sam’s dick was still pulsing away inside of him.
Then Sam looked away, choosing instead to nose at Dean’s head and rub his
cheeks over it, scent-marking Dean vigorously.  Any other time, Dean would have
laughed at Sam’s antics, but he was still a bit put off from that look.  It was
a look he’d only ever worried about seeing on his own face.  He must have just
imagined it.  There was no way that Sam could—
“Dean,” Sam said happily.  “Dean, Dean, Dean.”
Rearranging his features into something that resembled a smile, Dean looked
around at his little brother.  “I know, kiddo, I know.”
Next time, he’d just have to make sure that he won.
Although maybe it wasn’t so bad to lose after all.
