****** The Inevitable ******
by Miss_Lv
Summary
     ‘Take care of Sammy’ and ‘listen to Dean’ was what their father would
     say when he pushed them together and left them alone far too often.
     The way Dean saw it, it was inevitable. Even with their shared blood,
     Dean was still an alpha and Sam was a beta, it was nature.
***** Chapter 1 *****
When Dean was a little boy, his father put Sam in his arms and told him to look
after him. That was probably his first mistake because his son took hold of his
baby brother and never forgot his father’s command.
When Sam was around five or six, Dean could remember his father holding his
little brother, telling him he had to go and he’d be back in a few days time,
promising even though he ended up days late. When his father beckoned Dean
forward he hurried to comply and didn’t argue when his dad transferred the
sobbing boy to his own arms.
“Your big brother will be here with you the entire time, he’ll look after you,”
their father had soothed and Dean figured that was his second mistake because
Sam clung to it. Insisted always that if their father wasn’t there Dean had to
be, always.
Neither mistake would have amounted to anything if maybe either of the
situations were irregular. But the older Dean got the less he saw of his dad
and the more he was left in charge of looking after Sam. Too many years left
alone together, too many ever-changing settings and faces with only each other
to cling too.
The way Dean figured it their father didn’t have any damn right to complain.
 
Since his early years he’d felt it long before he understood what it was, what
it meant, a little urge in him to take all of Sam’s time and attention, to let
no one else near him. Strangers were dangerous after all and Dean kept Sam
close, held his hand wherever they went, was protective and ready to glare at
anyone suspicious. It wasn’t like Sam minded, he called Dean his best friend
and the elder brother was always proud of the title.
When puberty came and went Dean found himself staring at his little brother a
lot more often. He started noticing the green specks in Sam’s eyes or the exact
shades of his messy hair, the way he chewed his lip when he was thinking or how
he sometimes sucked his thumb at night when Dad wasn’t there to see. It was his
strange obsession that revolved around his little brother, but it was harmless.
Dean managed to convince himself of that; clung to the lie with everything he
had until the day Sam became a beta. Then Dean desperately tried to ignore it,
pretended with all he had in him that Sam’s scent didn’t affect him. It was
easier back when they were still kids, when Sam’s scent was soft and his body
too young to really be truly bred. But each year he grew up so did his scent.
It got stronger every time his heat came and Dean learned to dread those days,
a week twice a year, those were the days Dean felt God was either testing or
tempting him and he could never decide which one.
 
The first time Sam went into heat the school pulled Dean from his own
classroom, telling him his brother was upset and wanted him. Dad was out for
the day, coming home in the evening so no one answered when the school called
the rental they were living in. Dean smelt it before anything else, the strange
sticky sweet aroma that he recognized somehow as Sam.
“He’s not hurting or anything, just embarrassed I think,” the school nurse had
explained to him as she cracked the private infirmary door open to reveal
Dean’s eleven-year-old brother, sobbing quietly.
“Hey,” Dean offered immediately and scrambling into the room, reaching back to
push the door all the way closed even thought the nurse had probably left it
open intentionally.
“Go’away,” Sam was on the floor with his back to the cot squeezed in the tiny
room, knees pulled up to his chest and his face hidden, muffling the words.
“You asked for me kiddo, you can’t tell me to leave after you ask for me to
come see you,” Dean teased gently, going to the tried and true method of
cheering Sam out of his tears. Settling beside his younger brother, he watched
him cry quietly into his arms for a moment before Dean sighed and dropped his
head back on the bed.
“It’s not so bad, you’re not hurt or anything right?”
“What do you mean!?” The beta snapped out, lifting his head to stare at Dean
like he’d suggested they shoot each other in the foot or something. “I’m…I’m a-
don’t you get it? I’m a stupid beta, a bitch, I’m not an alpha. ”
“So? What’s wrong with that? Are you saying beta’s are stupid?”
“…no, you know what I mean, I just, I just wanted to be like you and dad,” Sam
confessed with a little hiccupping sob and Dean pushed in closer, his little
brother immediately dropping his head to Dean’s shoulder. “I thought I was
gonna be an alpha, I wanted to be, I really wanted to be one,”
“There’s nothing wrong with being a beta Sammy, it kinda cool actually,” Dean
offered and watched the boy blink up at him, still young enough to believe his
big brother’s judgment on what was good or bad.
“Really?” He asked, voice unsure but looking for an answer.
“Well yeah, I mean you get to have kids someday,” the moment he said it, his
little brother’s nose wrinkled in distaste and Dean knew it wasn’t the best
thing to say.
“That’s not anything cool,” Sam grumbled but his tears had stopped so Dean
figured it was a win anyway.
“Maybe not right now but one day it will be, you can like…give life Sammy,
that’s kinda awesome. All me an' dad can do is hunt, and… well take it away I
suppose, kill things,” coming from a fumbling teenager, Dean later figured it
had actually been pretty eloquent of him. “But you can do the opposite. Mom was
a beta, she got to have us and she always said it was the greatest thing she
could ever have done,”
“Did she really?” The tiny voice made Dean press up closer to his brother, he
knew how much it would mean to him to have something in common with their
mother, to hear something she had said.
“Yeah. It’s one of the few things I remember her saying,” he admitted, slipping
his arm around his brother’s shoulder and pulling him in close for a tight hug.
Sam didn’t resist and crawled into his lap. His damp pants seeped into Dean’s
jeans, but he ignored it in favor of comforting his brother.
“You’ll see, one day you’ll realize being a beta is awesome,” he reassured his
baby brother and pressed a kiss into his hair.
Dean barely managed to talk the school into letting him take Sam home, dad had
to call them as soon as he got back but in the end, they still let them leave.
Dad got in fairly close to when he figured so it worked out. Sam was thankfully
asleep so Dean had the time to explain everything, make his father understand
how upset Sam was. In the morning their dad was been nothing but proud smiles
and warm congratulations, both kind of rare for him and Dean figured it was the
key factor in ensuring Sam thought being a beta wasn’t all that bad after all.
Sam stayed home for a week as expected and their father stayed with him the
entire time surprisingly. Dean tried not to be jealous since he had to go to
school still but every time he got back his dad and brother would be doing
something fun, watching old movies, working on impala, and other things they
didn’t get to do often enough. But it made Sam happy and Dean always got to
join in once he was home so he pushed his jealousy away and tried to focus on
looking after his baby brother. Now that Sam was a beta it changed things. Dean
had always felt the need to look after him but now it was double fold and their
dad was no better. Thankfully, rather than feeling trapped by their over-
protective nature Sam was happy with the attention.
Becoming a beta turned out to be a blessing on their family, something Dean
never failed to tell his little brother if only to watch him flush and look so
adorable. For the first time in a long while John Winchester was pulled away
from his restless hunt. An alpha like Dean could handle himself well enough,
but a beta needed to be looked after in his mind. It was a tad chauvinistic but
in their case it was true, Sam yearned for the attention that their father
didn’t always give when they were growing up. Hunting had consumed him in those
early years but now seeing his sons grow up seemed to yank him out of it. They
spend more time as a family and Sam was beyond happy with that, even if it
meant he constantly had two shadows keeping an eye on him.
 
Sam was sixteen and in the middle of his secondary heat for the year, when a
hunter their Dad had worked with a few times called in a panic. His partner was
missing and the guy was sure the demon he was hunting was closing in on him.
Dean figured the mention of yellow eyes was the closer for his father. But Dean
wasn’t a kid anymore; he could look after Sam just fine on his own and his
brother wasn’t some weakling.
“I’ll have the phone close by so if you need to call,” their father said for
the sixth or seventh time before Sam finally scoffed and rolled his eyes.
“Dad, seriously. Dean is way worse than you, I’m surprised he even lets me go
to the bathroom alone,” the teenager teased and Dean was the one scoffing then
but words seemed to help ebb the worry in their father’s eyes. “I’m not useless
either you know,” the beta added with a bit of an annoyed tone. “I can aim a
gun better than both of you,” he boasted and both alphas knew it was a fact;
Sam always outshot them when they practiced. With a nod, their father reached
out and ruffled the teenager’s hair, making Sam roll his eyes again and shrug
out of the touch, exasperated but not really bothered as he stepped in for a
hug from their father.
“You take care, both of you. Dean,” The elder brother straightened his back a
touch and looked up at his father, gaze sharp. “Take care of Sammy,” It was
more than an order, it was his father trusting him to be strong enough to take
over protecting their family and he gave a curt nod, accepting that
responsibility.
Despite being a handful of months shy of twenty-one, Dean was still holed up in
a bedroom with his younger brother. It had always been that way, their dad had
never suggested Dean take his own room and Dean had never complained. It was
another thing that Dean figured his father should have seen as a really bad
idea rather than letting their need to be overprotective make the choice. The
current rental was small and the bedroom was cramped with two single beds
stuffed in it.
It was past midnight and the windows were all closed tight, the house locked
down and the salt lines checked over. A loaded gun was on the nightstand
between them and a knife on the floor between Dean’s bed and the wall. Dean
felt calm and sure, certain he could look after his brother.
Though it would be a hell of a lot easier if he could actually get some bloody
shuteye.
“Go to sleep man,” he grumbled and Sam’s hand lifted into the air from his bed,
his middle finger raised. It made his brother snort and smirk, but the
amusement faded as Sam kept moving around on the noisy bed.
“Seriously Sammy,” Dean groaned, tired but unable to sleep with the creak of
bedsprings, with the knowledge Sam couldn’t sleep and might get up in the
night, might not have Dean watching his back if he fell asleep and Sam didn’t.
“Shut up, this bed sucks,” The younger teen complained and Dean gave a long
huff. He looked over when Sam finally kicked his blanket down and sat up in the
bed. Before Dean could ask him what he was doing, the teenager abandoned it and
came over to Dean’s.
He half expected his little brother to try and kick him out, but Sam just
slumped down beside him, their bodies pressed side by side snugly in the tiny
mattress.
“Shut up,” Sam said before he could comment and Dean obeyed, knowing being in
heat sucked for Sam lately. When he was a kid it was a week off and hanging out
with dad, getting his way every single day for a week; but now that he was
older his body responded more, his scent was deeper, his physical reactions
were stronger. Dean didn’t ask for the details of it, but he understood his
brother was pretty much uncomfortable in his own skin for a good long week. So
he didn’t say anything, just let his brother crash all shoved up beside him and
listened to his breath finally even out as he fell asleep. Sam reeked, it was
that sticky sweet smell. Certain that his brother was asleep, Dean couldn’t
help but let himself take a long inhale of it. He’d always kinda liked the
smell of it though he wasn’t dumb enough to ever mention it. An alpha wasn’t
supposed to like the smell of their beta sibling. But the last few heats had
been different, he wasn’t actively trying to hump his brother or anything but
he just wanted to hang close, keep an eye on him. It wasn’t just about
protecting Sam though, Dean liked being close so he could stay in contact with
that smell. He felt himself twitch in his boxers and winced, immediately trying
to force sleep and ignore that he was half hard.
 
Dean woke up early.
Like really early, sun just barely lighting the room early and that was wrong.
Because unless dad was standing over him telling him to get his ass up for a
five am morning run Dean was all about sleeping in, more so when he got to bed
late. But as he slowly dragged himself to the land of the living he realized it
was far too early and what the hell had woke him up?
The answer became pretty clear when Sam made a soft hitched sound and Dean came
completely awake, the instinct to protect Sam roaring through him. Only problem
was that he was still in the bed with him. Dean was on his back, squished
between the wall and his sibling while Sam was on his side, facing away from
Dean and using his big brother’s arm for a pillow. Dean laid there for a second
getting his bearings and he realized he was laying there with a massive hard
on. Which actually made sense because by the tight little motions Sam was
making, his beta brother was currently masturbating.
Jesus Christ.
It was wrong, wrong, wrong, totally inappropriately wrong. Dean had heard
family was immune to each other, that the heat of a beta sibling wouldn’t
affect an alpha. Where was this supposed immunity now? With Dean throbbing in
his boxers, Sam’s one leg pressed against his thigh, tangled with his leg so
Dean could feel each little jerk. Sam’s back pressed into his side and his hand
brushing Dean’s hip- his hand. Without thinking about it, Dean looked down,
followed the line of his brother’s arm and realized he had his hand behind him,
in his boxers, in his ass. Without his consent Dean’s body let out a groan and
Sam gave a sudden whimper and a flood of that sweet smell hit Dean and left him
dizzy.
Sam had to know Dean was awake, had to know his brother was aware of what he
was doing. The beta had to smell the scent of an alpha, of Dean’s own arousal.
But his little brother didn’t jump up and get all embarrassed; he didn’t rush
to the bathroom and slam the door, rather he just kept touching himself. Right
there pressed up to Dean, Sam fingered himself until his gasping turned frantic
and with a little mewling sound, his body suddenly went stiff and then slack.
Dean didn’t look at his little brother, just slid himself out of the bed and
ran to hide in the shower and jerk off.
 
“Have you ever knotted someone before?” Sam asked him over their rickety dinner
table that evening. They’d spent the day at odds with each other, Sam just
watching Dean and the alpha fumbling like an idiot under the scrutiny.
“That’s….not an appropriate question man,” Dean managed to choke back, staring
at his plate of macaroni and cheese, determined not to look at his baby
brother.
“Since when have you worried about appropriate?”
“Sam, fuck, just…just drop it please,” he hated how much of a plea that was but
his brother didn’t say anything after that.
 
When they packed into the bedroom again, Sam didn’t ask, just slipped into the
bed with Dean again.
“Please let me, I won’t do that again. I’m sorry if I what I asked earlier
pissed you off but just let me…I sleep better like this,” while his little
brother whispered the words Dean let the tension in him melt, knowing damn well
that ‘no’ and Sam didn’t mix when it came to his will power.
“S’fine,” he finally muttered and his sibling pressed into his side, curled up
under Dean’s arm and gave a happy sigh. Sam drift off fairly quick, but Dean
spent most of the night fighting the urge to cop a feel off his baby brother,
wondering if Sam would welcome it. When his dad got home the next morning Dean
was deliriously relieved.
And maybe a tiny bit disappointed.
 
Sam’s next heat of the year came while they were crashed out at Bobby’s place.
The older hunter immediately invited them to stay the duration since traveling
was dangerous with Sam in that state. The hotels they stayed in where no place
for a young beta in heat to be, God only knew who would come snooping after
that sweet scent. Dean spent most of the time buried inside an engine, fixing
beat up vehicles and doing anything but hanging around in the house. Sam spent
most of his time in the window reading old books, a good distance away from
Dean but still in sight when he looked up. It both relieved and frustrated the
alpha in him. Seeing his brother whenever he glanced up put the tightly wound
fear that something horrible was happening to his beta brother at ease. But it
simultaneously was a temptation that Dean was starting to question why he
denied himself.
“Sammy’s not talking much,” Bobby pointed out over dinner one the third day and
the teenager in question glanced up from his plate and gave a little shrug.
“It’s not unusual, some beta’s get like that,” Dean’s father replied easily but
didn’t acknowledge the silent question. A beta going silent was a sign they
were falling more into their instincts, more into the primal side that all
humans, alpha or beta had wired in them. The primary cause of going silent was
when a potential mating was near. So it wasn’t a shocker the next day when his
father asked him if he had noticed Sam hanging around any alphas over the last
few months. It was his chance and he knew it. This was the moment that Dean
could open up his mouth and tell his dad the truth.
‘I’m attracted to my baby brother and I’m pretty sure he’s all up for it. I’d
appreciate some guidance and maybe a good beating since it doesn’t seem like
such a bad idea these days.’
Dean looked up from the engine he was working on and saw Sam sitting by the
window, idly reading some old book. The beta sat in the window all the time
because he knew it made Dean feel better to be able to see him.
“Not that I noticed.”
‘Dean Winchester, you are going to hell’ he thought to himself as his father
nodded and believed him entirely, they went back to fixing the stalled engine.
‘But it might be worth it.’
 
Dean slept in the study on a too small couch while Sam was in the living room
beside the study in plain sight if Dean left the doors open. Bobby and their
father were in the two rooms upstairs. As per his usual, Dean came in late
after working himself into a totally exhausted state. Sam was always sacked out
on the couch and Dean would curl up on his and not think perverted thoughts.
It was the fifth night and Dean knew that the last days were the hardest,
that’s when Sam’s scent was the strongest, when his brother stayed holed up in
the bathroom or bedroom and when he did come out to eat, the seat of his pants
were always damp. It was obviously excruciatingly embarrassing for Sam, he wore
the pads they made to soak it up all week but during the final days he always
soaked them through. Those days were the roughest for his little brother so
when Sam slipped from the couch in the midnight hours, Dean didn’t send him
right back because he felt bad for his brother.
And he’d spent pretty much the entire night hard as nails, as soon as he walked
into the house and caught the sweet scent.
Sam didn’t say anything, just went to his knees beside the couch and rested his
head on Dean’s shoulder. Awkwardly, Dean lifted his forearm and twisted his
hand around to pat his little brother’s hair.
“Just a few more days,” Dean assured him and Sam gave a little whimper in
reply. In the darkness of the room, Dean listened to the rustle of fabric and
then the wet sound that made his dick throb. Sam pressed his face to his
brother’s shirt and dropped both his hands down between his own thighs. Without
a word Dean just laid there and listened to his brother masturbating, listened
to the wet slick sounds and knew Sam was fingering himself. He didn’t try to
touch him, but he left his fingers in his little brother’s hair, felt Sam's
body moving as he thrust his hips and panted soft sounds.
Dean wasn’t sure how long it went on, minutes, hours, but he just laid there
and let Sam do it, let him rub his cheek on Dean’s shoulder and breath in his
heavy aroused scent while he got himself off. When Sam did finally stop he was
sweating and it made Dean’s shirt wet.
“S’not enough,” the beta whispered in the darkness and Dean gave his damp hair
a quick light pet before he dropped his hand away and Sam went back to his
couch.
 
Dean went out the next evening. Borrowed a truck he helped fix and drove two
towns over to a college city with crowded bars full of people around his age.
For the majority of the evening, he hustled pool and hung out with a hot beta
girl with pretty hazel eyes. When Dean would glance up at them real quick, they
looked like someone else’s. He figured he’d wrap up the game, take the
winnings, fuck her in the back of his truck and be home before four.
That was about the time he walked in. One look at him and Dean knew straight
away that there was no way in hell he was of legal age, not him or the majority
of the group he came in with. He stood tall and lanky, still awkward in his own
body in that familiar way and he had the right haircut, a few shades darker but
still close, really fucking close. High cheekbones and the same lips, not
perfect but damn closer than usual. Dean was all over the beta the second he
left his friends to go to the bathroom.
Once the kid finished pissing and turned to leave Dean backed him into a stall,
kicking the door closed.
The beta froze up, eyes going huge with fear and Dean slapped a hand over his
mouth before he could cry out.
“S’ok, not gonna hurt you, promise, not going to hurt you in anyway,” he
whispered hurriedly to him, pressed him into the unyielding surface of the
stall and angled their hips just right. He watched the teenager scent him, take
in a whiff of Dean and find there was no aggression in him, just pure lust.
Dean kept them tightly pushed together, rolled his hips and shoved his thigh
between the kid’s legs to rub up against him. When he caught the answering
arousal in the teenager’s scent his licked his lip and dropped his hand from
the boy’s mouth, leaning in to claim his mouth.
The beta fumbled around, all innocence still while his hands fluttered unsure
where to go while Dean traced the inside of his mouth with his tongue. Dropping
both hands down he squeezed the teenager’s ass and grinded him down on his
thigh. It was rough and fast, a desperate edge and the kid just went with it,
let him do what he wanted, just like Sam would if Dean wanted.
Fuck.
Spinning the boy to face the wall, Dean undid the kids jeans and pushed them
down and without hesitation, Dean pressed his finger to the boy's slicked hole.
The beta’s hands on the stall curled into fists and his breath went shallow as
Dean fingered him, added a second and worked his own jeans open. It was rushed,
too fast, too hard and it wasn’t fair to the kid but Dean didn’t have it in him
to be kind. He pressed in close, licked the back of his bare neck and lined
himself up. He waited a moment, let the kid have time to protest, but the beta
just pushed back a touch.
The teenager gave a whimper when Dean entered him, slid up and pinned him to
the wall so he couldn’t escape it.
“Shh, doing good, really good,” he managed to sooth him and then proceed to
fuck the teenager harder than he had ever done before. Every lunge went deep
and Dean grinded into him, took the slicked body with all the desperation that
had built up in him. He thought of someone else, thought of hair a little
lighter, thought of hazel eyes and shallow little breaths, of the sweet scent
of his brother.
Dean came with a hiss, it wasn’t a true climax, just a little gush that felt
awesome but not as good as knotting would. An alpha only knotted with a beta in
heat though and Dean had never dared to do so before, so the brief fleeting
release was all he knew and for once it wasn’t nearly enough for him. Dropping
his head to the teenager’s trembling shoulder, Dean knew how utterly fucked he
was.
Easing out and putting himself back into his jeans, Dean jerked the teenager
off with one hand and fingered him with the other, made up for using him by
getting the kid off with the best of his tricks. Touched him, licked, sucked,
and nipped until he was a whimpering mess and had painted the stall with his
come and his slick wetness all down his thighs. Afterward, Dean helped him
clean himself up, pulled the kid’s pants back up and took him back to his
friends. The group fell dead silent and watched with wide eyes as Dean gave the
teenager a parting smirk and left without ever learning his name or giving his
own.
Halfway back to Bobby’s Dean made a pit stop at an all night porn shop and
drove the rest of the way wondering how the hell he was going to deal with his
father in the aftermath of all this.
The front door was locked, but he knew where they would leave a spare key for
him and Dean slipped in, not surprised to see the light of the tv and hear it
turned down low. Locking the door back up, he kicked off his shoes and padded
down the hall. The house was dark save for the living room, but Dean checked
the kitchen and study to make sure no one else was awake.
“Hey,” he muttered into the silence and Sam completely ignored him, eyes locked
on the tv, the beta looked about ready to cry as he turned his back to Dean.
The alpha wasn’t an idiot, he knew why the beta was so upset, he could smell
the guy on him still and he knew Sam did as well, knew his brother could smell
the sex.
“I got this for you,” Dean tried, dropping the black nondescript bag on the
couch beside his little brother. He was ignored and Dean watched a single tear
track down his brother’s face. With a sigh, he leaned over the back of the
couch and draped an arm around his brother’s shoulders, pulled him back into
the one-armed hug so he could rest his brow in Sam’s short hair.
“I fucked him because he looked like you but it wasn’t enough, they never are.”
He whispered into his brother’s ear and pressed a soft kiss to his hair before
he left the room and passed out on the couch.
 
Dean woke up late and rubbed the sleep from his eyes with a lazy stretch. It
was sometime in the afternoon and the house stood still and empty. He managed
to make it over to the coffee machine in the kitchen and threw back some
lukewarm caffeine while idly looking out the window and watching his father and
Bobby huddle under a hood together. Smirking, Dean figured he should get out
there pretty soon because while his father and Bobby could work together as
hunters without flaw, the two alphas always ended up fighting over mechanics.
The soft creak of the stairs gave him warning before the rich scent of his
brother drifted into the kitchen. Pretty much every window of the house sat
open during the day, but it was still an overpowering smell. Today was Sam’s
last day and it was the peek for his body, the scent made Dean’s mouth water
and his dick go stiff. The silent lure was consuming enough that when his
brother appeared only wearing a towel and took hold of his wrist, Dean went
without thinking about how stupid an idea it was. Sam took him upstairs to the
bathroom where his clothing was scattered on the floor and the small room
reeked of his masturbation. Dean knew Sam had spent the morning in there,
getting himself off over and over.
Dean’s sixteen-year-old little brother dropped the towel, kept hold of Dean’s
wrist with one hand and reached for the plastic dick Dean had bought him with
the other. With all the mental capability of a rock, Dean just stood there and
watched as his brother pressed the toy up inside him, he just stared as Sam
gave a pleasured wince and the fingers around his wrist squeezed. With quiet
little moans, the beta proceed to fuck himself with the toy and gave Dean’s
hand a tug, made him step close and then guide his hand back to the base of the
dildo.
Sam wanted him to fuck him with the toy.
Dean wondered if it qualified as a form of torture.
“I..I can’t,” he choked out but his fingers still gripped the end of the toy.
“Fuck, Sammy, Dad or Bobby are gonna walk in,” Dean tried to warn even as he
pushed the toy in a bit just to watch his brother squirm. Sam stepped towards
him and closed the distance between them, he gripped the hem of Dean’s t-shirt
and pressed his face to Dean’s neck, shaking his head in negative before
motioning to the window. The bathroom was directly above the kitchen and Dean
could see the two alphas outside, just make out their blurry shapes through the
faded fabric curtain pulled closed. He could see them, but they couldn’t see
them.
Sam pressed his face into Dean’s neck again and rolled his hips, gently rocking
back and forth on the toy. The smaller boy pressed his naked body close, his
arms looping around Dean’s middle and clutching at the back of his shirt
desperately, rolling his hips into each motion.
Dean glanced outside, made sure his father and Bobby were still out there
before he gave a soft curse and dropped his head to press his mouth to his
little brother’s messy hair. Giving him a soft kiss, his fingers finally did
more then hold the toy as he began to work it in and out of the beta clinging
to him. Sam’s grip on him went tighter and the boy buried his face in Dean’s
shirt to muffle his cries, going up on the tips of his toes so Dean could reach
his ass better.
“Shh, baby,” the alpha muttered and pressed the toy as deep as it could go,
felt his brother’s legs shake a little as he held it up inside him. “You like
that?” He questioned pointlessly as his brother whimpered and pushed back on
the toy.
Dean glanced out the window again, checked to see both the other alphas still
outside, unaware. Wrapping his other hand around Sam’s waist, Dean lifted him
off the floor, twisting them so Dean’s back hit the wall but Sam now had his
back to the mirror. It was just low enough to give Dean the view he wanted.
“Be a good for me and reach back, spread yourself so I can watch Sammy,” Dean
instructed him and with a breathless moan the beta obeyed, reaching back and
cupping his ass, spreading it so Dean could see his brother’s stretched hole,
watch the toy gleaming with his slickness as it moved in and out of him.
“Look at you, fucking yourself back on it so desperately,” licking his lips,
Dean watched transfixed on the pink hole forced wide, on the wet sounds that
came each time he stroked the toy back. “Acting like a bitch in heat,” he
muttered more to himself than his brother but Sam keened, pressed his face into
Dean’s neck and sobbed quietly.
“You like that? Like being called what you are, a hungry little bitch, cock
hungry for your first knot?” The words made Sam writhe, press closer to Dean
and shove back on the toy frantically. Dean’s opened his mouth and obscene talk
spilled out, filth that obviously turned his brother on as Sam kept getting
more and more desperate at each dirty word. The term bitch was reserved for
mates, a bitch was a beta that had an alpha, it was a term of endearment and
commitment. Dean had never called any of his lovers his bitch before.
“Such a pretty bitch,” he whispered, dropped his head so his mouth was right
beside Sam’s ear. “My little bitch, gonna be mine someday? Gonna take my knot?”
With a broken little cry, Sam’s body froze up and Dean felt the wet trickle on
his fingers as his brother came all over the dildo. Warmth seeping on the front
of his shirt telling him Sam’s cock had erupted as well. The beta slumped
against him, panting for air and a sheen of sweat making his skin glow in the
weak light. Holding him up with one arm, Dean carefully eased the toy out of
him and stared at his brother’s little pucker.
Looking outside quickly he checked on his father and Bobby before he let his
hand drift down and gently flutter over his brother’s little hole. Sam gave a
whine when Dean touched him, carefully rubbing a single finger over the slicked
up entrance. Sam was puffy and red, he looked well used and Dean wondered how
many times he had fucked the toy already. Circling the hole, he slowly applied
more and more pressure until the tip of his finger slipped into the soaked
passage. Sam’s body seemed to pull at him, trying to grip him and take more and
Dean swore harshly, eyes locked on the mirror as he watched his finger slide up
into his very willing sibling.
Sam’s hand cupped the front of his boxers, rubbing at Dean’s crotch, at his
painful erection and the elder brother jerked, coming out of his fixation on
Sam’s body. Pulling his finger free and he quickly put space between then,
fumbled to get out of the room. Sam grabbed at him, tried to make him stay and
Dean pushed Sam back suddenly, forced him to the wall and slammed his mouth to
his brothers. Kissing him long and hard, tongue shoving in and roughly claiming
what he wanted. Sam reacted wildly, rolling his hips and grabbing at Dean
frantically, trying to get his leg on Dean’s hip, pulling a his boxers,
desperate for it, desperate to find the relief only Dean’s knot could give him.
The alpha broke away again though and pulled away, taking Sam’s hands from him
as he moved away.
“Can’t… can’t Sammy. What’s the point of it now? Dad will catch us, he’ll know
if we knot. Your heat almost done, gotta wait, be good for me and wait, next
heat, next heat I’ll make sure it’s just us. Just you and me all week and I’ll
take care of you then,” he promised his brother as he backed out of the room,
slammed the door closed and held it when his brother tried to yank it open. The
broken whimpers from his little brother made him want to open the door, but
Dean knew better. If his father caught them he would separate them, everyone
would. Dean wasn’t doing this for a brief fuck if he was going to take Sam it
was going to be for good and no one, not even their father, was going to come
between them.
 
“’M sorry for being a jerk,” Sam told him after a few days of being a prissy
mean little thing towards Dean.
“Oh?” He pushed with a raised brow as he half focused on putting in a new fan
belt, doing a few last repairs for Bobby before they took off onto the road
again.
“Don’t be an ass, it’s hard for me when I’m in heat, it makes me crazy,” the
beta grumbled but leaned against the side of the truck and handed Dean the new
belt when he was ready for it.
“I know. I get that it sucks for you, but you see why I said no right? You
would have reeked, we both would have and when Dad found out, he’d probably
send me to Antarctica of something,” Dean glanced up and watched his brother
frown and give a little nod, looking out to where their father was helping
Bobby move some metal sheets down into his basement for some safe room project.
“He’s gonna know eventually,” Sam replied quietly and Dean gave a sigh but
didn’t argue the eventual fact.
“If we do it right he won’t know for a long time Sam, by then he won’t have the
choice to split us up,” the alpha reasoned and watched his little brother go
stiff. “What? You figure it would be a one-time thing? Come on Sammy, I’m gonna
knot you, just you, my first time.” Straightening up, Dean glanced at his
father before leaning into his brother personal space. “Gonna knot you over,
and over, and over,” he teased, voice low and amused as his beta blushed
crimson.
“Whatever,” Sam tried to grumble but his scent went strong and Dean laughed out
even as his brother punched his arm hard enough to make it numb.
 
They spent the next months going back and forth, Dean unable to decide if he
was horrid human being or if he was a horrid human being who didn’t care. Some
days he’d look at Sam and wonder what their kids would look like and others he
would peer at his baby brother and tell himself he was sick to even think about
it.
To make things better or maybe worse, depending on how Dean was feeling that
day, their dad picked up that something was going on. He never mentioned
anything outright, but his gaze got sharp. Dean had thought he had hidden his
sexual reaction to Sam’s last heat well; the powerful scent of the beta had
covered most of his own aroused smell. But he could see a question starting to
build up in his father’s eyes so Dean did his best to never ever even think
about touching his brother. Sam wasn’t exactly impressed, but Dean knew better
than to even dare to kiss him, knew how keen his father was. A string of
girlfriends he went through also helped to throw their dad off the trail. It
also served to cool Sam down as well, even if it meant he was in a constant
state of being pissed off at Dean.
“Do you fuck them?” He demanded one night, their father off gathering
information for a few hours. Lately, he took one of them along, always kept his
kids close and his eye on at least one of them. But for whatever reason they
had a rare moment to themselves and as usual, Sam wanted to stir up a fight.
“Sammy,” Dean sighed back, tired and not up for the same argument again. “Just
drop it please,” he requested and got a dirty look in reply. The beta stood
firm, waiting for his answer and Dean gave a second, deeper sigh.
“Yes. I fuck them,” he admitted and wasn’t surprised by the well of tears in
Sam’s eyes or the guilt that it put him through. “You’re my baby brother,
this,” he motioned between them silently, “is really, really fucked up.”
“You should be with someone else, someone right for you, not your big brother
because you don’t have any other options,” Dean tried to explain and wondered
if he believed his own words. They were true he supposed, Sam should be with
someone else, but Dean was a possessive selfish bastard when he really thought
about it.
“If I wanted someone else,” Sam growled back and suddenly closed the distance,
hugging Dean with all his strength. “I’d have gotten someone else, stop being
dumb.” Dean didn’t have a reply to the almost desperate tone of his sibling,
but he didn’t push his brother away either.
“Do you ever call anyone else your bitch?” The beta asked and Dean knew he was
caught then.
“No Sammy, I’ve never.”
 
The build up to his next heat was an unspoken push-pull between them, a silent
battle. Dean would chase after other betas and try to convince himself that
they would be enough and Sam would just watch quietly, waiting for Dean to come
slinking back, which he always did.
Thankfully the tension between them was misread by their father and he lost
that worried look about him, let his suspicions go and stopped dragging them
both on every single hunt. When Sam’s next heat finally came around, it was
almost two weeks early. While the exact days were never certain, they usually
were fairly close, a week or so from the six-month marker. This time though it
was two full weeks before Dean would have started to expect Sam to go into heat
and it caught him off guard. While he knew there was no way for the youngest
Winchester to control his body, it just seemed too perfect. Their father had
just left on a solo hunt, nothing major but nearly half way across the country;
he wasn’t due back for two weeks at the earliest.
When Dean woke up he found a note on the fridge explaining that Sam had not
only gone into his heat early, he’d decided to walk to the high school and
explain the situation and get his homework for the week. That right there told
him that the note was, in fact, a notice to Dean that his brother was being a
surly little bitch to get back at him. But what Sam suffered in heartache
because Dean wanted him to be a normal kid, Dean suffered in panic attacks and
vivid imagery of his baby brother being brutally raped somewhere.
Their dad had left them with a shitty old truck that needed time to warm up and
coaxing to stay running. Dean hadn’t gotten to fixing it up yet and he cursed
himself for being lazy as he shoved his feet into his sneakers and took off
down the street on foot.
Sam was waiting for him. Sitting in the office of the high school and swinging
his legs back and forth, a picture of devious innocence.
“You little bastard,” Dean growled and his brother offered him a smug smile
while the secretary made a scandalized sound and frowned at Dean. He realized
then that in his haste he hadn’t changed. Wearing a wrinkled sleeping shirt and
dirty jeans, shoes with no socks, hair going everywhere, panting for air and
looking irate for no clear reason, yeah, he probably looked like a responsible
kinda guy.
“Come’on, we’re going home and I’m locking you in the basement for the next
week,” he threatened, partly for Sam’s surprised look and the secretary’s
shocked sound. With a mixture of embarrassment and amusement, Sam got up and
gave the lady a little nod, hefting his bag on his shoulder and following Dean
out of the school.
“Expecting a ride or something?” Dean questioned when Sam looked for their
truck and his brother raised a brow and frowned at him.
“If you’d waited for me to drive you,” he explained with a shrug, trying to
play his early panic down but his brother must have seen something because he
bumped into Dean roughly, hugged his arm tightly and looking apologetic.
“S’alright, just….don’t do it again man, don’t think my heart can take that
kind of strain,” the joke fell flat but Sam nodded his head and seemed to take
Dean seriously.
 
They walked back at a far more leisurely pace, Sam never completely letting go
of Dean and the alpha never trying to shake him off.
They walked quietly, for the most part, Sam sticking close until they reached
the woods. There was a path cut through the green belt to their house and once
they were in the woods Sam moved a little ways ahead of Dean, still holding his
hand until he was too far and he slipped his fingers free. Sam looked back,
smirking playfully as he kept just out of Dean’s reach.
“And what are you up to?” He asked his younger brother as he picked up his pace
to close the widening gap between them. But Sam increased his own speed and
stayed ahead, getting further away until Dean darted forward. Sam narrowly
avoided his grab and broke into a run as Dean followed on his heels.
“Sammy,” he warned but his voice lacked true fear, his little brother was
playing and while he was working to avoid Dean he wasn’t actually trying to get
away.
“Thought you couldn’t wait for it?” Dean teased and made another dive for his
brother, his fingers brushing Sam’s arm but not enough to get a grip. Sam’s
backpack was abandoned with a thump as the beta took up a real pace and Dean
had to push himself to keep up. His alpha brain was going haywire, a perfect
potential mate was ready, eager to be bred and now he was challenging Dean,
daring him to capture him, to take him.
Despite the uncomfortable pressure in his jeans, Dean kept up with his brother,
closed in and when Sam stumbled it gave Dean the moment he needed to overtake
him. Grabbing Sam by the arm he swung him, broke his momentum and pushed him
down to his knees but took the brunt of the fall himself.
Sam scrambled to get his footing and Dean yanked him to his body, trapped him
in an embrace as he pushed them down to the dirt. His beta squirmed and tried
to wiggle free his breathing coming hard and Dean felt himself throb. He wanted
Sam panting for another reason; he wanted to feel the heat of Sam’s body around
him.
With Sam pushed down on his stomach in the dirt, Dean pressed his chest tight
to his brother’s back, felt the curve of Sam’s ass rubbing along his cock and
just tempting him all the more. Dean’s head softly collided with Sam’s shoulder
and the alpha rained rushed kisses on his shirt, pulling the material until
Sam’s neck was exposed. He ravaged the skin with a frantic edge, inhaling the
staggering scent like it was a hit of the best drug, licking and sucking while
his hands fumbled to get Sam’s jeans opened.
The beta whined and arched away from Dean still giving a few token struggles
but spreading his thighs and helping Dean get his jeans down. The seat of his
brother’s jeans were soaked and his boxers were far worse, clinging to his skin
in a sticky mess that made Dean’s mouth water. Slick caked his brother’s hole
and was smeared all around, the clear slippery excitement that proclaimed Sam
in heat and ready for breeding.
Licking his lips, Dean sat back and without warning bend down to lick a long
trail up his brother exposed ass. His tongue ran over Sam’s little pucker and
his hole fluttered as if inviting him in. The beta under him went completely
still, breathing ragged as Dean licked at him, tasting the slick and feeling
high off the powerful scent he was inhaling.
“Such a wet little bitch, so eager, God Sammy, you’re dripping,” Dean muttered,
attention riveted on his brother’s pink hole. He rubbed along the rim with his
tongue and fingers, touching and tasting while his brother gave choked whimpers
and swayed his hips.
“Look at you, humping the air, desperate for a knot, for anything in this
greedy little hole,” as Dean spoke he pressed his fingers down, slowly sinking
his digit in and feeling his cock throb at how hot and slick Sam was on the
inside. The wet body felt perfect and Dean jammed a second finger in, trying
not to rush preparing his sibling but at the same time unable to fight his own
eagerness.
Sam was already lost in his body’s urges; moaning and rocking himself back on
his brother’s fingers. His body was virgin tight and Dean knew he had to be
careful; the first time stretching to take a cock and then a knot was the
hardest for a male beta. But God, the scent and feeling of Sam were making him
light headed.
“Gonna take you now, make you mine,” Dean muttered, fumbling to get himself
lined up with Sam on his hands and knees and Dean right behind him, pushing his
jeans down. His skin felt too tight and his body overheated. He had heard about
alpha’s reacting to a beta’s heat and Dean had caught a whiff of ripe scents
before and never felt like this. It took everything in him not to just slam
into Sam all the way, to force the beta to take him and then lock him with his
knot, giving Sam no choice but to be bred by his brother.
The surge of dominance was hard to fight back, but Dean managed focusing on Sam
and the fact this was his first time. With care Dean rubbed along his hole and
heard Sam whimper, pushing back eagerly, he was soaked and Dean made sure his
rim was well slicked before he took the head of his cock and pressed it along
Sam’s opening. The boy keened, head dropping as he thrust back blindly at Dean,
looking to impale himself.
“Easy, we got to go easy,” Dean soothed him, rubbing the small of his brother's
back as he rubbed the length of his cock along Sam’s hole, smearing the slick
and making sure to get all over his dick. His cock was pulsing hard and the
alpha had to squeeze the base painfully tight to keep the knot from swelling
too soon.
Once he was nice and wet Dean pressed up against Sam’s hole again, this time
pushing harder, pressing the slippery tip of his dick up into the tight hole of
his little brother.
“Gonna fuck you, gonna knot you and breed you, bitch.”
Sam was arching his back and moaning as he pressed back, sinking on Dean’s
cock. His body was tight, but it parted easily, ready to take a male as Dean
fought the need to be brutal. Sam was useless in helping him keep calm, the boy
whimpering and panting for it, pressing back and looking over his shoulder at
Dean with dark desperate eyes.
Dean swore as he breached finally, the moment years in the making as Sam
pressed back sharply, forcing half the length in before Dean caught his
brother’s hips. “Easy, take it slow bitch,” he growled the back of his mind
still worried about tearing Sam. But the beta looked far from pained, Sam was
whimpering, his hips swaying, urging Dean in deeper. The heat was controlling
his little brother now, making Sam into a desperate beta to be bred. Licking
his lip, Dean watched his cock disappeared further into the pink stretch of his
bother’s hole. Pulling back slightly he didn’t see and blood and let himself
relax a fraction. Sam pressed back harder and Dean let him, watched the length
of his dick sink into the sweet heat of his little brother.
“Like that?” Dean couldn’t help but ask, tease with the way Sam was moaning
happily, his ass pressed flush to Dean’s hips as he took every inch of Dean
into him. Parting his thighs a little, Dean braced himself and took his Sam’s
hips, pushing him off a little and then easing him back, starting a rhythm.
Despite his good intentions of taking it easy, instinct slammed into Dean hard.
His fingers started digging into the soft flesh of Sam’s waist as he yanked his
brother back a little rougher, pushed him off a little further, the easy rhythm
dying as things turned frantic again.
“Fuck, you feel amazing Sammy, feel so perfect,” he panted out, his hips
snapping hard as Sam cried out with every thrust. The harsh slap of skin and
the wet sound of Dean’s cock sliding home accompanied his noisy brother and
Dean knew anyone on nearby paths would overhear the mating. It gave him a
thrill, knowing others might see them, that they would see that Sam was Dean’s
in every way now.
Swearing, Dean yanked Sam closer and adjusted them, spread their thighs wider
and pushed Sam’s shirt up higher so he could see more of his brother bare. With
on hand on the small of Sam’s back and the other still on his hip, Dean resumed
thrusting, angling his hips high and snapping into his brother with slow but
hard lunges, Sam giving a keen each time Dean fucked into him.
“Feel so good, a perfect bitch, my little bitch,” Dean babbled pointlessly,
unable to shut up as he rode his little brother and felt the first blissful
pulse of his body knotting. He nearly lost it right then, this was the first
time Dean had truly knotted and the pleasure was staggering. Leaning over Sam,
Dean’s rhythm turned frantic, fast short thrusts where he bared pulled out of
his brother.
“Fuck it’s- God, Sammy, I’m gonna, I’m knotting baby, gonna tie with you and
fill you up, breed my bitch, mine,” The feral thing in Dean was riding high
now, even if their father caught them Dean wouldn’t have stopped, not for
anything as he felt himself throbbing and pulsing, Sam’s cries getting louder.
Dean grabbed at the beta’s thigh and yanked back, right onto his lap and he
held Sam there, the smaller boy grinding himself as Dean swore a blue streak
and felt himself swelling up. Part of his mind wanted to keep thrusting, but
Dean ignored it in favor of tying securely with Sam. The beta was whimpering
happily as he clawed at the dirt, clearly feeling the bliss of their first
knotting as well. Dean could feel Sam clenching down on him and he meant to
reach down and jerk Sam off when the pleasure hit him. It came in a hard rush,
his hips jerking mindlessly as he panted and felt his knot firmly locked inside
Sam. Now the pleasure rushed over him, the orgasm taking control as Dean was no
better than Sam, a panting mess as he rutted against his brother and felt
nothing beyond the all consuming pleasure as they climaxed together.
They ended up on their sides, spooned together with their jeans around their
knees. Dean leisurely sucked love bites all over Sam’s shoulder and neck,
nuzzling him lovingly. Every few moments they’d both tense up and ride out the
dizzying pleasure as the climaxed over and over, each time Dean pulsed and
filled Sam, the beta’s body responding and the two of them shuddered through
the thrill.
Dean had no real idea how long they were tied together in the dirt like that.
But eventually he rocked his hips and felt his knot shift, signaling it was
going down and Dean would be able to pull out soon. With care, he tried slowly
and when Sam made an uncomfortable sound he settled back, waiting it out until
Dean pulled back cautiously again and slipped free from his brother.
He felt like he’d run a marathon and then spent the night on an intense hunt.
But despite his weariness Dean managed to get his jeans back up and tug Sam’s
too. The beta was totally incompliant and gave pitiful whines as Dean made his
brother get up and come home. By the time they were under the threshold, Dean
could see why Sam hadn’t wanted to walk. The seat of his jeans was soaked right
through, the heavy scent of their mating clear. It simultaneously made Dean
pleased and irritated; proud to have his claim on Sam but annoyed to see his
seed wasted. Sam was in heat and he needed to breed the instinct in Dean
muttered, chanting that he needed to knot with Sam again right away since his
seed was leaking from the beta.
They made it to the bedroom and despite his weariness; Dean eased between Sam’s
thighs and took him again, knotting with the beta in a slower more intimate
breeding. The frantic rush wasn’t present as Dean kissed Sam, coaxed his mouth
open and licked inside while his hips rocked. Sam was all shy to be on his back
and facing Dean, his gaze looking up at his brother and then darting away as
the alpha chuckled.
“Now you’re self-conscious? You just screamed your lungs out in a public
place,” Dean teased lightly and watched as Sam flushed prettily. The bed
springs gave soft creaks as Dean pushed up into Sam a little harder, let Sam
feel it as Dean pumped into him, feeling his knot already starting to swell up
again. After they tied Dean turned them so Sam’s smaller weight was on him and
let the beta rested as Dean stroked his hair and watched him, feeling like a
corny creeper.
 
They waited for a late hour to go to the all-night pharmacy. Dean didn’t want
strangers looking at Sam in his condition but simultaneously he couldn’t let
the beta out of his sight long enough to run to the store alone. So they went a
two in the morning, holding hands while Dean bought a variety of things for his
brother’s heat. Sam didn’t offer a single word, when Dean’s hands lingered over
the after-knot pills. He’d always intended to get some since Sam was only
seventeen, but Dean had underestimated how much Sam’s heat would crawl under
his skin. A voice in his head was whispering insistently that Sam was his now,
it was his right to put a pup in him, his responsibility to see Sam pregnant by
the end of his heat. It wasn’t a little thought either but rather a screaming
thing that pounded in his head that Sam should be pregnant, that he’d look so
right with Dean’s child in him. Swallowing, Dean dropped his hand away and
glanced at his little brother. Sam peered at the pills and then shrugged, more
interested in the chocolate on sale then the pills that would prevent a baby.
if the urge was in Dean yelling away he couldn't imagine how hard the instinct
was roaring though Sam, the one in heat. Dean glanced at the pills again and he
felt guilty but unable to reach for them again as he turned away and ended up
letting Sam buy a heap of expensive chocolate instead.
It buzzed under his skin the entire drive back to the rental. The idea of Sam
getting pregnant was spinning around, the guilt not stronger than the
excitement of it. It was small and petty of Dean, but he knew it would tie
them, that starting a family would ensure Sam stuck around. Dean would be a
good alpha to him, he'd provide and make a home for them. Sam had always
dreamed of settling in somewhere, a small town with a community college he
could go to. Dean could give him those things, he could make a life so his
brother was happy with them, so they could be a family. The thoughts built up
in his head and by the time they got back to the house, Dean unceremoniously
threw his brother on the couch and yanked his pants right off him. It was a
fast mating, Sam all willing and happy to be fucked while Dean couldn’t stop
thinking about fill his brother up. He came hard and loud as they knotted and
he spent the entire time thinking about the seed he was pumping deep into the
fertile beta. Male pregnancy was pretty rare so Dean eased his guilt but
thinking that it was up to nature now and that if it was meant to happen it
would.
Although it was probably cheating when Dean used the anal plug they got from
the pharmacy to keep his come inside Sam.
 
As the days progressed along Sam fell deeper into his heat and Dean spiraled
down as well. By the third day, he couldn’t handle the thought of other alphas
scenting Sam, kept him inside the house and glared at the fast-food deliver
brats, making them sweat bullets under Dean’s growl. Sam didn’t seem to care
much about it though, as long as Dean was fucking his brains out constantly. On
the fourth day, Sam came into the living room naked and crawled into Dean’s lap
like it was nothing. He opened his big brothers jeans and unceremoniously sank
down on Dean’s dick. They didn’t manage to leave the couch until the next
morning.
The fifth day felt strange. Dean scented Sam continually trying to place what
was off, but he couldn’t figure it out. They fucked wildly throughout the day
and sometime in the night Dean realized what was off. Sam’s scent hadn’t gotten
deeper, hadn’t kept building up to the level it usually got during his heat.
By the middle of the sixth day, Sam’s heat was gone.
 
“You know what it means right?” Sam asked him, sitting on the bed and watching
his brother settle on the floor so he could put his head in Sam’s lap.
“Are you pissed?” Dean just replied and Sam shrugged a little.
“I'm not mad, I wanted it eventually, but this it a little earlier than I
expected,” he admitted and Dean poked a gentle finger at his brother’s flat
belly.
“If you’re not ready for this”-
“I said I wasn’t expecting it not that I wasn’t ready.”
“If you're sure,” Dean muttered, pressing between Sam’s legs so he could slide
close and press a kiss on his stomach. He pulled Sam down into his lap and gave
his brother a warm kiss as well.
“What are we gonna do? How will we explain this to dad?” Sam asked with a
nervous huff.
“We’ll figure it out Sammy, I promise,”
“But what if-”
“No matter what I’ll be right here with you, always am right?”
“Stalker,” the beta muttered but his worried look abated.
“Love you too.”
 
Their father had taught them this, set them up for this fall. Dean was to above
all things take care of Sammy and Sam was to listen to Dean. What else could
their father have expected of them then for a young alpha and beta to become
mates.
***** Chapter 2 *****
Chapter Summary
     Timestamp.


John wasn’t comfortable with it, this was incest that his sons were happily
committing and when he first found out it felt like someone yanked the ground
out from under him.
Dean had never been a rebellious alpha. Everyone always told John he’d have to
keep an eye on Dean when he got older, that one day the boy would break away
from John’s dominance. But Dean had always been fine with following orders,
he’d never argued about anything. It was Sam who kicked up a fuss; it was the
beta of their family who like to argue, which Bobby thought was hilarious.
Bastard.
For a long time John wondered if it was his fault, if he should have split them
up more as kids or something. But wondering didn’t change anything, didn’t make
Sam any less pregnant with his own sibling’s baby. Jesus. John remembered the
night he caught them together, the night he realized whose kid Sam was
carrying. The angry words flying while Sam screamed at John and cried and
cried, cupping his belly possessively while Dean stood in front of his brother,
like he needed to defend Sam from John, like he would hurt his own son. 
He’d been so angry, so disgusted with the entire situation that he’d gotten
into the car and drove off, left to clear his head. A few days later when he
returned, his ultimatums were useless because his sons were already gone. They
stayed with Bobby for months on end, the older alpha sheltered them even when
John told him the truth, told him what they had done, what they were doing. 
John didn’t know what to do, he couldn’t force them apart if Bobby kept them
safe, he couldn’t make his sons see their sin. So he hunted. He let it take up
his life completely; all that mattered was killing the monster and then finding
the next one.
He missed his kids like a phantom limb, always reaching for the phone to check
up on them before he caught himself and realized they wouldn’t be on the other
end anymore. When he had enough drinks in him he’d let himself think about it.
Think about his sons together and at first it was nothing but disgusting. But
as the time wore on John realized that he never once questioned if they loved
each other. For all his anger and betrayal, he never once thought it was
fleeting or just sexual and he didn’t know if that made it better or worse.
What would Mary think of it? What would she say in the face of this? Love is
everything she used to tell him and it haunted him now as he thought of his
sons.
He could remember the one summer at Bobby’s place when Sam was in heat, not
long before Dean and Sam started their… their relationship. John remembered Sam
giving the signs of a beta looking for his mate, remembered thinking something
was off between his boys. But when he’d kept a close eye on them all he could
see was two brothers at odds with each other. Maybe he hadn’t wanted to see it,
maybe he’d ignored the obvious and looked away while his sons fell into their
incestuous union. John spent way too many evenings with a bottle of Jack
pondering the thoughts, wondering about it all until his temple ached.
 Bobby was bad for pushing John to accept it, hell even Jim was on their side,
supporting them and what they were doing.
“It happens John, those boys are good and while it’s not something I’d normally
condone…its just them, it’s Dean and Sam, nothing is going to come between
those two” he would say, a man of the cloth for Christ’s sakes.
Ellen got to him worse than anyone else though; she’d call him up in the
evening after he had a few drinks, when she knew he wouldn’t hang up on her.
Rather than telling him to accept it, that it was done and couldn’t be broken
like Bobby or Jim, she’d just talk about them. It was the most horrific thing
to hear about them, to learn that Dean was working at a mechanic shop and
helping Bobby hunt when he could. That Sam had finished highschool and was
going part time to college now. John would just sit alone in a dark empty motel
and listen to Ellen talk about how excited his sons were, that they had saved
up enough money to by themselves a little house. That Sam had forged documents
with a fake last name so he and his older brother could get married.
It was too much to hear, too much to think about, it broke him down so
thoroughly until he was standing there, feeling so out of place and wanting
nothing more then to get back into the car and drive away. But it’s been too
long and John missed his kids, he missed his family too much to keep running
from this. After every hunt he would go back to his boys and no matter where
they were, when he arrived back it always felt like home to him. They made it
home and John needed that feeling back far more then he disapproved of their
mating. 
“I was starting to wonder,” was how Ellen greeted him, leaning against the
doorway as she looked at him with a hard assessing gaze. “Don’t hurt them
anymore, they don’t deserve that,” she scolded before going back in, leaving
the door open behind her.
It was a small place and it needed work, but it was the home of a family, it
was lived in. There were lights strung up and garland hanging everywhere,
bright Christmas things that Sam always liked as a kid. John could see a
Christmas tree shoved into the living room and hear the chatter of people in
the kitchen. Bobby, Jim, Ellen and her daughter, hunters that were around as
Sam and Dean grew up had come to celebrate Christmas with them. 
John had barely closed the door when his eldest son appeared in the narrow
hallway. Dean looked good. He looked too old but healthy and well rested, his
expression was unsure, flipping between varying emotions as he padded down the
hall to John.
“How’s the impala?” Dean finally asked after they stared at each other like
gunslingers.  
Neutral ground.
John’s chest felt too small and each breath was a little painful.
“It’s good, got a bad dent in the passenger door, but- it’s good,” he managed
to get out gruffly, feeling too emotional but Dean was no better, nodding his
head once and then reaching out of his father. It didn’t occur to John not to
accept the hug, not to embrace his son. He didn’t agree with what Dean and Sam
have done but he’d never once not seen them as his boys, his sons.
By the time they pulled away from one another John’s eyes were wet and Sam was
standing there, right beside Dean with his swollen belly. The beta looked so
terrified as he looked up at John, like he was scared of his own father. It
broke John’s heart all over again and he raised a hand, not knowing if Sam
would accept it, they’d always fought. But in a heartbeat his youngest boy was
in his arms, hugging him tight enough for it to hurt a little. With little sobs
Sam clung to him and John rocked him and shushed him gently, like when he was a
little boy in John’s arms.
“I missed you boys,” he muttered into Sam’s hair and looked up to see Dean nod
his head, eyes wet. Sam’s belly was pressed up against John and his boy was far
along nearly ready to pop he thought.
“Will you meet her?” Sam finally whispered, his voice pleading and John gave a
weak nod and steeled himself. Everyone had moved into the living room, some
Christmas show played on a little tv even though John didn’t doubt for a second
they’d all moved to eavesdrop easier. There were greetings all around and a
heavy air of anticipation.
Dean plucked a tiny little girl off Bobby’s lap and tucked her to his hip. The
child giggled happily and hugged him close, blabbing nonsense words. 
“Mary,” Sam said softly, drawing her attention as he walked up to them and
gently caressed the girl’s golden hair. “Someone special is here to meet you.”
The little girl turned her eyes on to John; bright and innocent as she peered
at him and he felt like this was the biggest judgment, the greatest milestone
he had to pass as everyone in the room held their breath. Eyes that were the
same shade as Sam’s peered at him for a moment before she turned and pointed at
a shelf across the room, pictures in framed all along it.  
“That’s right kiddo,” Dean said with a proud tone and John could see the
picture she was pointing at. It was three years old, taken just before their
family fell apart, John and his sons all looking at the camera with ease, a
hunt finished and people saved.
The little girl looked back at him and reached out a tiny fist to him.
“Gran-pa.”
John felt like for the first time in years that he was home.
