First season SPN where after being on the road with Dean for awhile, Sam notices he hasn't built a nest once. He's confused because Dean used to nest all the time when they were kids, and he's worried because he knows how important nesting is for hormone regulation in omegas, but every time he brings it up Dean just brushes him off. He comes to understand that the nests Dean used to make in the shitty motel rooms of their childhood weren't really for Dean; they were for Sam. Children with an omega parent need nests growing up, and in Mary's absence, Dean stepped up to the plate. So Sam starts to wonder how he can make Dean see nesting as something he does for himself, not others.
Then it turns out the whole time Dean was nesting, albeit he was doing it subconciously. His nest is just the Impala.

You’d been on heat suppressants your entire life. It was just easier that way, and your parents never really minded it. You were never super curious about what your heat would be like off of suppressants anyway. At least, not until you started dating your boyfriend, Sam, who happened to be an alpha.
It’d been four months dating him, and he was the sweetest guy you’d ever been with. Well, he was the only guy you’d been with ever, but that didn’t make him any less of a sweetheart. By the second month, you had started to wonder what it would be like to have a real heat, one without suppressants, with him. He’d never been on suppressants and was always an open book when it came to his rut, but you’d never spent it together with him.
When you told him that you were an omega, just on heavy suppressants to make it seem like you were a beta, he hadn't minded at all. In fact, nothing about your relationship had changed at all. Sam was still just as sweet and caring, and after having a conversation about wanting to go off of suppressants to experience your heat in its entirety, he was completely open to taking time off just to spend it with you. And that was exactly what he did.
Sam had helped you with making your nest, turning your bedroom into a makeshift den of sorts. The bed was covered in soft blankets, some of your favorite shirts of his, and pillows he’d brought over from his own apartment. He was sure to put care into it, his scent permeating most of the items that you’d used.
It was obvious your heat was approaching, and fast at that, your pheromones smelling “sweeter” as Sam had described them at least. As your heat had approached, you’d gotten more and more nervous about the experience. It had reached a peak this morning when you woke up with your body feeling hot, hotter than usual. By the afternoon, you felt as if you were drowning in the scent of Sam’s pheromones, his woody and slightly minty scent enveloping you like a hug.
Sam was over in a heartbeat when you’d called, practically panting out your words from how overwhelming his scent was. When he’d gotten to your apartment, you were curled up in your nest, one of his shirts against your chest as you squirmed in your nest. It felt impossible to get comfortable, the heat within your body burning hot along with the ache in your lower abdomen.
Sensing Sam’s presence had you wanting to pounce onto him, logic hitting the fan as your instincts overtook any solid thought that was left in your fuzzy head. Despite the urge to move, your body was too weak to make any extreme movements. All you could do was roll over to face him, your sweat-slicked bangs sticking to your forehead as you panted out his name softly.
“Shh, I'm right here,” he soothed gently, rushing to sit next to you on your bed. He’d brought a bag of stuff that he’d set down next to the nightstand, stuff that seemed to be snacks and things of that sort. He could read you like a book, sensing your anxiety and slight confusion from the fresh feeling of your instincts. “Just breathe,” he whispered softly, rubbing gentle circles on your back.
“Feel so achy, Sammy,” you babbled, feeling slick pool in your cotton panties as you breathed in his fresh scent. Your body could practically sense that he was there to help, that he would be the one to save you from the hot pit in your stomach.
He could smell your arousal, the scent overwhelming as he felt his own instincts start to awaken inside of him. “What do you need, love?”
You let out a whine before tugging on the sleeve of his shirt, looking him in the eyes with pure desperation shining through your pupils.
“You know what I need,” you huff under your breath with an attitude. The desperation and pure need to feel full makes you frustrated with his dumb question.
“I need to hear you say it, baby,” he murmurs, eager to hear your verbal consent before touching you any further. “Need to know exactly what you want”
With a small sigh, you manage to mutter out your request. “I need you to touch me,” you pleaded as your panties dampened at the overwhelming amount of slickness between your legs.
He hums, his hand pushing your panties aside with a gentleness that feels all too well. His fingers glide against the slick lips of your cunt, rubbing slow circles right against your clit. “Like that, hm?”
The feeling of his fingers against your heated pussy has you reeling as you nod eagerly, your hips rutting up against his fingers, desperate to feel more of the sweet pleasure he’s providing you with.
Sam knew that you weren’t going to last long in this state, that you’d just keep getting more and more insatiable the longer he made you wait for release. “Lift your hips, love,” he purred as he insisted on removing your damp panties.
You simply hum, whining as he moves his fingers away to take your underwear off. Lifting your hips, he hooks his fingers into the waistband of your panties, peeling them down your thighs before throwing them aside.
“Atta girl,” he praises as he takes in the sight of your swollen, glistening folds. “Gonna make you feel so good.”
He spreads your legs with care, settling between them as he rests your thighs on his shoulders. Sam knew you craved his touch with every fiber of your being, but he also knew that he had to hear your approval before acting.
“Tell me what you want, doll,” he urged. “Do you want my mouth on your pretty pussy?”
You let out a small hiccup, nodding impatiently.
He takes your nod as a green light, not needing any further encouragement from you before he leans in and drags his tongue along your slit. Groaning softly, he slowly laps at your folds as if savoring your unique flavor. After a few teasing licks, he focuses his attention on your clit, circling at the nub with the tip of his tongue before gently sucking.
With a needy squirm, you cry out his name as your fingers tangle in his brown hair as if trying to ground yourself from the pleasure. As he suckles at your clit, his tongue swirling around the nub, you feel your cunt throb eagerly. “S-Sam,” you babble with a shudder as he starts to get more sloppy with his assault on your pussy.
Pulling away with a soft kiss to your clit, he coos lowly against your pussy. “Cum on my tongue, princess.”
He wastes no time latching back onto you, giving a particularly hard suck as he feels your slick drip down his chin. His actions are thoughtless yet passionate, his own instincts making him eager for more of you.
You tug on his hair gently with a soft cry as you feel your head roll back in pleasure. A rush of your juices leak onto his tongue as he hums, as if encouraging your orgasm. He slurps every drop with fervor, his eyes watching as you come undone on his tongue. With a loud, sloppy pop, he finally pulls away from your glistening cunt.
“That’s my good girl,” he rasped as he pressed a final, feather-light kiss to your cunt.
Despite your fresh orgasm, you still feel that deep-seated pulse in your stomach. Sam doesn’t even need to hear you say it to know that you need more, that you crave more than what he’s already given you.
“My insatiable little omega,” he teases. “I’ll give you what you want, baby.”
With that promise, he drags his fingers against your folds, feeling as more slick leaks from your needy pussy. He circles your entrance with a single, thick finger before pushing it in slowly, giving you time to get used to the feeling before curling it right against your sweet spot.
Your hips buck as you let out a gasp, lips parting as he starts thrusting his finger in and out.
“That’s my good girl. Can my doll handle another?”
A small squeal falls from your lips as he continues to curl his finger against that sweet spot. You nod eagerly, desperate to finally feel him inside of you.
Feeling your walls flutter against his finger, he happily obliged, pushing another finger inside of you. He pumps both of them in and out, still aiming for that spongy spot inside of you before scissoring them inside of you to stretch you out.
Slick drips down his fingers as you let out a strangled moan. “Sam— Fuck!”
“Is it good love? Tell me how my fingers feel inside you.”
Your mind is virtually blanking from the pleasure, eyes fluttering closed as you struggle to get the words out. “‘ts so good.. t-too much- close—” You pant as he hits that spot.
He feels you clench around his fingers, your pussy right on the edge. Curling his fingers against that spot one last time, he pulls his fingers out despite your annoyed whine.
“I know baby, shh,” he coos. “Gonna give you what you need.”
Sam fumbles with his belt as he takes his pants off, his boxers following with them as he pulls out his cock. He settles between your legs, pressing a soft kiss against your lips before delicately folding you into a mating press.
“Is this okay, baby? I’ll go slow,” he promises, pressing your thighs against your chest. “Gonna breed you s’good.”
Lining his cock up with your entrance, he mutters softly. “Just relax princess.”
He pushes in gently, the swollen head of his cock pressing into you as he lets out a low groan as you clench around him. Slowly, he pushes further inside of you, fighting the urge to just slam inside of you in one thrust.
You let out a noisy whine, nibbling at your bottom lip as you feel him sink into you inch by inch. His cock already feels deep despite him being only halfway in. “S-Sammyy—”
“Shh, almost done honey,” he whispers against your ear. “Just a little more.”
Finally, he bottoms out inside of you, the head of his cock kissing your cervix as he stills inside of you. Your walls flutter around him as he lets you get used to the feeling of being so full.
“There’s my good girl, letting me fill her up so good.”
Tiny tears well on your lash line as you let out a breath you hadn’t known you were holding in. “‘ts so deep.. feels like you’re in my stomach-”
He hums, starting to rock his hips slowly inside of you. “Gonna move now, okay doll?”
With that, he begins to move, his hips rolling in a lazy rhythm. He pulls out almost entirely, leaving only the tip inside before pushing back in with a deep and steady thrust. Keeping that slow pace, he groans as he feels her walls fluttering with each deep thrust.
“Is this good, baby?” Sam mutters against your ear. “Feels good?”
You nod with a gasp as you feel his cock hit the spongy spot deep inside of your cunt, wrapping your arms around him as he starts to slightly pick up the pace.
“I got you, baby,” he murmurs as he peppers gentle kisses along your temple.
Your heart races against his chest, each thrust deeper than the last as the ache inside of your cunt finally starts to disappear. Your omega instincts completely take over as your breath comes out in short, sharp gasps.
“Come on princess, cum for me,” Sam babbles, feeling his own release start to near. He picks up his pace once more, his tip pressing right against that spot with every thrust. “Gonna cum inside you.”
“Pleasepleaseplease— gonna cum!” You cry out, thighs trembling as you start to feel that coil inside of you unravel.
“Don’t fight it baby, let it happen,” he encouraged through his own moans. The sloppy wet sounds of his cock slamming into your soaking cunt echoes throughout the room as he makes love to you right in your nest.
Your cries grow louder and more insistent as you start to tighten around his cock, right on the edge of release.
“That’s my girl, go on,” he breathes against your ear as he gives you one final thrust to push you over the edge. His cock kisses your cervix one final time before he feels your body stiffen as your walls convulse around him.
Your orgasm hits you like a tidal wave as you clamp around Sam’s cock, moaning his name loudly as you feel him cumming hot ropes of his own cum inside of you.
His hips grind against you as he rides out his own orgasm, working his cum deep inside of your quivering cunt. “Good girl, my good girl.”
Sam flips you over onto his stomach, his cock sinking deeper inside of you as you let out a small whimper in protest.
“Shh, we’re done for now baby,” he purrs against your ear with a soft kiss to your lips.
You couldn’t imagine going back on suppressants again, not after how good he made your first real heat feel. Sighing softly, you mutter blissfully against his chest, “Never using heat suppressants again.”
teenage Sam in the early stages of his alpha presentation growling everytime John touches Dean or tells him what to do, getting into fights at school because his classmates won’t stop talking about how pretty his big brother is, unconsciously scenting Dean every time he sees him, not listening to anything John says and ready to get in a screaming match with him at the drop of a hat. So full of restless energy and anger and stubbornness and possessiveness and all of his overwhelming instincts he doesn’t know what to do with
i really like the weecest omegaverse, i wish there were more (but with the kind of dynamic i like)
a pre-teen alpha sam being territorial with omega dean is exactly what i need. He's still very young, but when dean is close to his heat, sam gets aggressive, even with john. Imagine a little puppy barking at anyone who gets too close. I'm sure dean doesn't always allow himself to go into heat anyway, probably only when there's no money for suppressants or he doesn't have the time. And sam makes sure he does when he's most vulnerable. Hearing dean suffer puts him even more on edge, and John has to approach carefully: "don't jump up and bite me or hit me, sammy. I'm just trying to help your brother. Dean needs his medicine. Can i come closer?" and sam looks at him like he's capable of leaping to bite him right in the jugular if he takes one more step toward dean
Thinking about Dean sitting in Sam's lap while they're cuddling. He starts acting goofy and being nippy- like, actually nipping at Sam's cheek and stuff. Sam laughs and tells him to stop, trying to block him, but Dean just keeps squirming until they're play-wrestling on the floor.
omega!dean, who in the lead-up to his heat is is quick to rile and slow to settle.
dean, who's constantly on edge, prickly and cranky at the world and everything in it: his t-shirts for being too scratchy against his stupid sensitive nipples, the motel sheets for smelling like bleach and a thousand passing-through bodies, his job for forcing him out amongst the people (he had to interview a literal bus load of witnesses today, all gussied up in his fucking fed-threads!) when he feels like this, like his skin's gonna peel off in sheets and he'll have to go around for the rest of his days with his flesh melting off like he's just seen the goddamned ark of the covenant.
dean, who can't even get comfortable in the impala, twisting in his seat like he's sitting on a bed of nails instead of the upholstery that's basically his birthright. he keeps jamming new tapes in the deck, skipping through the tracks, and listening for no more than forty seconds before slamming the 'eject' button and popping in a new one. (sam fights the urge to give the dashboard a little there-there pat when dean's not looking.)
dean, who can't decide on where to eat, but turns up his lip at every suggestion. he keeps picking up vienna sausages and canned fruit cocktail and moon pies every time they're in a convenience store, then looking confused when the he sees them on the checkout counter. dean, who's been mowing through the specialty power bars sam bought back at the knot shop in downer's grove, the ones that had incomparable density fights calorie deficit! and 26g of pure protein to power your heat! scrawled in bright blue lettering on the box that sam immediately emptied into a plastic grocery sack before dean could see the packaging.
dean, who's been jacking little things out of sam's duffel every time they do laundry. an orphaned sock here, a t-shirt with holes under the armpits there, two pairs of underwear that sam's pretending not to notice inside dean's pillowcase.
(sam used to bug him, when they were kids, about his nesting habits. the teachers and textbooks in secondary sex-ed always had diagrams and lists of things omegas might put in their nests; duvets and couch cushions and throw pillows, blankets and leak-proof sherpa throws, specialty bamboo temperature regulating blankets. dean never wanted any of that. he just wanted sam, as close as he could get him. a good heat was one where dad would ditch them someplace, and they'd get to curl up together under the same plastic-poly motel coverlet and two sets of over-bleached sheets, all fingers and teeth and dark and warm and wet as twins sharing a womb. a bad one was spent in the front seat of the impala, trying to catch peeks of dean in the rearview without their dad noticing. dean, huddling alone under a poncho-liner, curled up around himself, hands pulled into the cuffs of his shirt, pale and sweating out the fever after dad had given him an injectable suppressant, the military-grade kind that you could buy from expired shipments out the back of army/navy surplus stores if you had cash in hand and the clerks were scummy enough.)
dean, who'll run himself ragged as his heat approaches, fighting the instincts dad hated (even though the man's dead and burned) and sam, who -- when he's finally had enough of this display -- will grab dean by the neck and squeeze until all the tension bleeds out from the impromptu scruffing, then pull back the covers of another anonymous motel bed. it's a clear invitation, and dean's never once turned him down.
When it's almost omega!Dean's heat, alpha!Sam works out more than usual and doesn't do laundry. When Dean's heat comes, Dean has a basket full of potently-scented clothes to build a nest.
it's all omega!dean and alpha!sam bc that just makes more sense in my head lmao sorry not sorry
Take a Load Off by submariner
Stories from Sam and Dean’s wet, hot, American summer (road trip).
Sometimes, he feels real bad, about what he lets Sam do. It’s dirty, and it’s wrong, and he knows it. In fact, the second time they did it, Dean got sick—so sick he thought he might be pregnant, which would have been even worse than anything else. But it passed, and so did the guilt. It’s Sammy: how bad could it be, really? Dean keeps looking over at his alpha, and Sam keeps jumping him any chance they get.
alternatively, five times Dean doesn’t come and one time he does.
Mina's note: starting with my FAVORITE. I love love love this one very deeply. we have a bunch of delicious flavors in here besides the omegaverse: weecest behind john's back, dean with a pussy (my beloved) and an unhappy ending (I mean, it's pre-series, so its not exactly the end, don't worry).
that's kinda personal, but dean not coming was very endearing to me, as an ace person that can't really get there with another person lol and that doesn't mean the sex was bad, there's various other reasons to fuck besides coming, and I like how this was explored here :)
The Bite of Knowledge by theproblematique
Omegas can tell when alphas are attracted to them. It's a survival mechanism.
After years of buildup, Dean finally realizes that Sam is attracted to him.
It's a shitshow.
Mina's note: that's the first wincest omegaverse fic I ever read, yay. It's super cute and has so much pining - which I love!. I really enjoyed the world building in this one, I never saw this thing where omegas know when alphas are into them, which is super cool.
To Sound The Depths by Pendragony
Dean has always set aside his needs, repressing his instincts for the sake of Sam. Sometimes he thinks he doesn’t even know how to be an Omega any more. When the brothers pose as a couple to investigate a spate of drowned Alphas, Dean starts to get back in touch with his Omega self. But when the heat is on, will Dean still be able to protect Sam?
Mina's note: this one is also on my long wincest fic rec post. It's a case fic as well and I really like the plot (truly, that's not a joke about porn), and it's somewhat of a slow burn, which is one of my favorite things ever!!
he ain't heavy by adastreia
Castiel was gone. Dean was asleep and probably would be for the foreseeable future. Sam should probably hit the hay himself, but something felt – off. Somehow he knew there was no way he’d manage to do anything but toss and turn if he did try and go to bed. There was a thrumming under his skin that once upon a time he would’ve associated with an impending rut, but he hadn’t had one of those since his soul (mangled, taped together, falling apart) was slammed back into his body. Couldn't be a rut. It was probably stress.
Mina's note: most omegaverse fics are heat focused, so I always jump at it when I catch a hut fic!! it's sooo hot, I don't know why there's so little alpha!sam hut fics out there, the self-hate is so delicious
darling, don't put down your guns yet by scorpiod
Dean accidentally gets pregnant. They both know they should abort it.
Sam and Dean decide to keep it.
Mina's note: pregnancy fic, obviously. S7, which is such a messy season to get pregnant, with the leviathans and halluficer around, so it's like soo interesting!! the way they act towards the pregnancy seems very canonical to me, and I love pregnant dean. there's a tiny bit of lactation kink, and little flashbacks to when they were kids that are so fantastically weird and fucked up - just how they are and just how I like it.
Taste Every Fruit by thatsakitkat
There's no real words to describe how feeding Sam feels. Dean thinks it might be better than orgasms, but it's a whole different kind of pleasure, one that makes him feel sleepy and proud of himself for being able to take care of his brother this way. Everything feels right in the world, all Dean's problems taken away in the gentle pulls of Sam's mouth.
Mina's note: very interesting world building!! and so much lactation lmao dean with boobs was something I didn't know I needed
Drip by thatsakitkat
Sam chews the inside of his lip and looks down at the tampon in his fingers, taps the applicator between the webbing of his thumb and index. "I'll do it," he offers, hopes his voice is even and doesn't crack or tremble because looking at the tampon, he can picture the string hanging outside Dean's body and it's weird, what that imagery does to him.
Mina's note: TAMPON KINK!!! I mean, I'm a bit insane about this, but yeah, tampon kink, guys....
Sassy Sammy and the Slick Tits by fastandfilthy (IndridGrey)
Dean has to take parenting classes in high school like everyone else and he has been given a fake baby. The problem is, his omega hormones have been going into overdrive recently, so the fake baby's crying is enough to induce lactation in him. Teen alpha Sam gladly offers to help him out.
Mina's note: the title is so funny and crackish lmao but as the author tagged, it's not as cracky as the title makes it sound - it's actually really hot. omegaverse + lactation kink is such a good match!!
