Being an Omega in this part of the world was nothing short of a nightmare - Omegas were treated as slaves and fuck toys for Alphas. When your parents had died, you were even more scared than ever before. Being left alone in this world was terrifying, you hadn’t told anyone, not until you’d met Sam Winchester. He was an Alpha through and through,” - at least, that’s what he let the outside world believe. To you he was your best friend, and your protector. He was a complete sweetheart, even when you knew it was hard for him not to give into his nature.
The most that he ever did was snap at you, but that was only when his rut hit particularly hard or your heat or his rut started before either of you were ready. Even then though, he would lock himself away, or he would lock you away and keep you safe, until those days passed. You wanted to want Sam in that way, and you knew he felt the same, but neither of you had ever been able to bring yourselves to do anything.
There were times you’d talked about it at length; the possibility of you being his, but you’d always come to the same conclusion. It wasn’t right, for either of you, and it wouldn’t be fair. You were worried though, because if Sam wasn’t supposed to be yours, then who was? And were they even half as sweet, hot and caring as your best friend? You only knew what you’d been told by your other Omega friends, once you found your mate, you would just know.
“You ready to go?” Sam asks as he walks into your room, with a big excited grin on his face.
“Sam, are you sure about this?” you sigh as you finish zipping up your suitcase for the weekend.
“Y/N, trust me! My family are going to love you.”
“You know I trust you, more than anyone on the planet, but I don’t know if It’s such a good idea. I’m not exactly special, I’m just like any other Omega,” you sigh as he takes the suitcase from your grip, and you hear him huff quietly.
“I’ve told you before, that isn’t how any of my family see it. Besides, you’re my best friend, they know how much you’ve been there for me. Even if you are a giant pain my ass. Now come on, stop complaining,” he winks at you over his shoulder.
You roll your eyes and follow him out of the door.
“Fine, but you better not leave me on my own,” you huff out, locking the door behind you.

Luckily the drive doesn’t take as long as you thought it might, and all too soon you’re pulling up to a gorgeous home, with perfectly kept lawn and two classic cars in the driveway. You wring your hands in your lap, feeling the nerves creeping up on you even more than you’d expected. You can feel the need to be sick pressing against the back of your throat. Sam must notice because seconds later you feel a big hand on top of both of yours, and you feel a slight sense of calm start to settle over you.
“Sam, I told you not to use those Alpha powers of yours on me,” you laugh slightly, feeling grateful that he doesn’t always listen to you.
“Y/N, you’re shaking and you’re breathing too hard. I don’t want you passing out on me, just breathe,” he smiles gently, the complete picture of calm, as always.
It takes a few moments, but you finally manage to get your breathing under control, and your heart stops racing.
“I don’t know what’s wrong with me, I don’t think that’s ever happened before,” you swallow thickly, climbing out of the car and following Sam as he pulls your suitcases out.
Sam looks you over and frowns, “now you mention it, I’ve never seen you like this. Did we work out the days wrong? Is your heat due or something?”
You think on it for a moment as Sam leads you to his parents house, and over to the front door.
“I, uh, no. I only had one a two weeks ago. You know I only have one a month, it can’t be that.”
Before Sam can respond the door is pulled open, and a grinning couple fill the doorway.
“Sam! It’s great to see you son.” The older man steps forward and embraces Sam in a tight hug, that Sam returns with a big grin. Before turning to the older woman and doing the same. It’s clear to see they’re his mom and dad. The family resemblance is beyond obvious.
“Mom, dad, this is Y/N. Y/N this is my mom and dad, Mary and John Winchester,” Sam introduces fondly.
“Great to finally meet you, Y/N! Sam has told us all about you,” John smiles warmly, giving you a quick hug which you return nervously.
“We really have heard so much about you, thank you so much for looking after our baby,” Mary grins, and pulls you into another hug.
“Now, come on inside you two,” Mary tells you both, moving aside so you can follow Sam into the house.
“Sammy!” You hear from down the hall, and you follow Sam further into the house, watching as Sam is embraced by a slightly shorter man with sandy hair. You smile at the display of affection. it’s so nice to see Sam surrounded by family, he’d always spoken about them, and you’re guessing this must be the brother he’d told you countless stories about, Dean.
Suddenly Dean looks up and his eyes lock with yours over Sam’s shoulder, you feel like a rug has been pulled from under your feet and you stumble back a little. Your heart thuds painfully in your chest, and you swallow thickly around the lump that’s lodged in your throat. You bite your lip as his nostrils flair and feel yours do the same as his scent hits you, and it’s like you can see his eyes darken before you.
Your words are stuck in your throat, until Mary comes to your side and wraps her arms around you, “Y/N? Are you feeling okay, sweetie. Do you need to sit down?”
Her voice sounds a little distant, like you have cotton wool lodged in your ears, but you hear her faintly all the same.
“Yes, please. Sorry, I don’t know what’s wrong with me today,” you all but whisper, tearing your gaze away from Dean, as Sam pulls away from him to come and stand by your side.
Mary and Sam lead you into the living room and help you get settled on the sofa.
“Are you okay?” Mary checks again, as she sends Sam away to help his father outside with the grill.
“Y-Yeah, I think so. I think I just need a minute, long drive,” you explain as you try and reassure her, and she nods in understanding.
“Okay honey, if you need anything we’ll just be outside okay?”
“Thank you, Mrs Winchester,” you sigh, leaning back against the soft sofa, and you let your eyes close for a moment. You feel her squeeze your hand and the sofa dips as she steps away.
You suck in a deep breath and your eyes snap open, as an unusual but tantalising mix of scents fill your nose. It’s like leather, spice, oil and something you don’t quite recognise. Then your gaze falls on the door you’d come through earlier, and on him.
You sit a little straighter and shift awkwardly in your seat.
“Hi, you must be, Dean. I’m Y/N,” you practically whisper as he walks further into the room.
He looks you up and down and licks his lips, his gaze heated, like he can see through your clothes and it makes you shiver.
“Nice to meet you, sweetheart,” his voice is almost a growl as he talks, and he takes the seat right next to you, holding out his hand for you to shake.
You take his hand and your eyes lock with his, a complete calmness settles over you and you can feel yourself leaning into him. Dean swallows, his Adam’s apple bobbing in his throat as he repositions his hand, so that his fingers are moving between yours, intertwining your hand with his own.
“Alpha,” you whimper leaning in closer, following his lead, until his forehead is pressed against yours.
“Omega,” he practically growls, scooting his body closer to you and breathing deeply, as his free arm curls around your waist tightly, almost possessively.
“There’s something about you… I don’t understand. I’ve never felt anything like this before,” you mutter, almost disbelieving, like if you say it too loud he’ll disappear.
“Neither have I, but I can smell it. I know you’re mine.”
He says it with such finality, and you want to believe him because, fuck, he’s perfect. Gorgeous, strong, great family. But beyond that you don’t know anything about him, you’ve literally just met, but something tells you that you can trust him, that he’s right, and you are his and he’s yours.
“B-But we’ve just met, Dean,” you stutter, as the hand gripping your waist slips just beneath your t-shirt and brushes your skin.
“Don’t care. You’re mine, I know you are. I can feel it, I can smell it, and I know you can too,” he growls as your free hand rests on his thigh to steady yourself.
“I can feel it, in every bone in my body, Dean. But we can’t,” you protest weakly, trying to pull away, but he holds your body tight against his.
He pulls back and looks at your face, “Is it Sam?” he huffs, and you can hear the unease in his voice, you can tell he’s forcing down a possessive growl.
“Why would it be anything to do with Sam? He’s my best friend, and that’s it. We both feel the same,” you sigh as he pulls away further, and you groan as your stomach rolls painfully.
“I’m sorry. You’re right, I’ll let you rest, just pretend this never happened, okay?” he grits out, voice shaking as he backs away slowly.
“No, Dean, don’t. I didn’t mean you had to go!” you call after him, but before you can get up he’s already left, and you hear the back door slam closed.
-
Dinner had been really great, full of great conversation and stories of Sam and Dean when they were younger, not to mention the amazing food. It only made you more confused as to why Sam never cooked more often at home. But after ten minutes, something had changed with Dean, and he’d gone to eat in his room, claiming that he had to make a call for work.
You’re all now sitting in the living room, while Mary shows you photos of Sam and Dean when they were babies. When suddenly a wave of pain hits you from nowhere, and you grip Sam’s arm tightly.
“Y/N? Are you okay?” he asks immediately, and he looks really worried as he takes you in.
“No. Something’s wrong,” you whimper, wiping at your sweaty forehead with the back of your hand. Sam carefully helps you to your feet and you cling onto him tightly.
“Mine.” Comes a growl from the doorway, snapping everyone’s attention away from you and towards Dean.
“Dean? What the hell do you mean ‘Mine’?” Sam questions defensively, putting himself between you and his brother, pushing your body behind him.
“Alpha,” you whine, reaching for Dean, and Sam has to hold you tighter against his side, so you don’t fall to the floor.
Everyone seems to be looking between you and Dean, before John groans quietly, “Fuck, I shoulda noticed earlier. Sammy you need to let her go, son,” he tells his youngest son gently, as he walks towards you and Sam.
Sam looks at his father as though he’s gone mad and holds you tighter.
“No way, clearly Dean’s lost his damn mind, he’s not going anywhere near her. I’ve kept her safe for years, but I didn’t think I’d have to protect her from my own family.”
Your eyes lock with Dean’s and you whimper as he starts to walk towards you, feeling the slick gathering between your thighs.
“Sam. Listen to me, Dean must be her mate. You said yourself that Y/N isn’t due a heat, right?” John asks calmly, stepping between his boys.
“Not for another two weeks, why? What the hell does that have to do with anything?!” Sam exclaims with disbelief.
“Well, your brother has literally just had his rut. So by rights, he was safe, unless…” John trails off, maybe hoping Sam is understanding.
“Sam, please. I need him,” you moan pathetically, as John growls at his eldest son warning him to step back, in an effort to calm the situation down.
“It must be another heat, Y/N, it’s the only explanation. You’re not thinking clearly-” you unintentionally cut Sam off, when a scream rips through your throat and you double over in pain, with Sam’s arms the only thing stopping you from hitting the floor.
Dean whimpers and looks around his father, locking eyes with his brother, looking like a scared puppy.
“Sammy, please. Let me help her,” Dean groans, running his fingers through his sweat soaked hair.
“No. I’m the one who looks after her, not you,” Sam growls defensively.
You’re starting to lose consciousness, and your eyes are heavy, sweat dripping from your forehead. You’ve never felt anything this intense in your entire life. Suddenly a smaller pair of arms wrap around you and help you sit back on the sofa, you look up at Mary, and she’s barely in focus.
“Honey, I need you to focus, look at me okay.”
“Can’t, Mary. I’m so tired,” you slur, feeling the sofa dip the other side of you.
“Doll, listen to me, you can’t fall asleep, you’re burning up.” Comes John’s deep voice from your other side, and you lean into him when he presses a cool rag against your forehead.
“‘mega, tell me what you need, let me help,” Dean whispers, carefully cupping your cheeks in his big warm hands. You force your eyes open, and you can see the pain in his eyes, and the tick in his jaw as though he’s clenching his teeth.
“Alpha, please. Need you, don’t go,” you beg desperately, reaching out and grabbing his shirt in your fists. Dean’s hands cover yours and he tries to hush you gently, and you notice that you’re both alone in the room now. Your legs are still like jelly, so when you try and stand you practically collapse into Dean’s arms.
You nuzzle at his neck and purr as his scent surrounds you, feeling your vision clear slightly as your lips press against his skin.
“Not here,” Dean growls, his voice deep, husky and thick with need as he scoops you up into his arms and carries you bridal style, putting a stop to your attempt to push his shirt from his shoulders.
You clench your thighs together as another wave of arousal grips you, and you feel Dean’s fingers tighten against your body as he carries you up the stairs. When you reach the second door on the left, Dean walks inside and then kicks the door closed behind him. He heads over to the large bed and lays you down carefully, before sitting down beside you, and brushing the sweat soaked hair away from your face. The familiar feeling of your heat coursing through your body is even stronger than it’s ever been before, and you can feel yourself curling around Dean as soon as he lays down beside you.
“It hurts, Dean,” you whimper, hooking one of your legs over his body as he wraps his arms around you and you find yourself rocking your hips against his thigh, trying to find some kind of release.
“Shh, sweetheart, just breathe. You’re makin’ it real hard to be a gentleman right now,” his voice is practically a growl, and it sends a shiver down your spine.
You bite your lip as you look up at him, “I don’t want a gentleman, I want my Alpha. I want you.”
Dean’s arms tighten around you and you feel the growl in his throat right before you hear it, “Fuck you smell good ‘mega. I could smell you as soon as you walked through that door. Haven’t stopped thinking about it since I first laid eyes on you.”
“I don’t understand how this all happened so fast, but I know you’re my Alpha, I can feel it,” you whisper as he cups your cheek and you feel relief flood your body when he pulls you into a kiss.
The kiss starts off careful and slow but quickly becomes more passionate, he gently pushes your hands back against the mattress, and you have to clench your fists to stop yourself from touching him.
“Stay there, baby, let your Alpha make it better,” he whispers against your lips between intense kisses that seem to be turning your body to liquid. Dean’s hands are exploring every inch of you, his touch is firm and a little rough, but it’s just what you need right now. You can’t help but moan into his mouth when he starts tugging at your clothes.
When he pulls away from your lips to look into your eyes, you gasp for breath, quickly realising only your panties remain. Dean hums in approval, cupping your breasts in his big hands and he gently flicks over your nipples with his thumbs, biting his lip as he watches your face for a reaction. You arch into his touch, desperate to feel more of him.
“Oh God, fuck,” you whine needily as Dean runs his fingers over your soaked panties.
Dean chuckles deeply, breath hot against your soft skin, and you shiver as he nips at your neck, “you want me to bite down just here,” he nips a little harder for emphasis, and you can’t help but moan as you struggle to nod. You arch your hips and moan his name as he pushes your panties aside, and he eases two thick calloused fingers inside your soaked entrance, slowly edging back and forth until they’re fully inside you.
“Mmm, of course you do, my needy little Omega. You want me to claim what’s mine? Want me to fuck you until you can’t see straight, and you’re coming all over my knot?” You can tell his instincts are taking over, his voice is deeper, and his touch is almost bruising, but in the best way.
Dean rips your panties away from your body with his free hand. You barely even feel the sting of them ripping, only the slight pressure on your clit as he pulls them up and off of you. Then he leans over you, and he starts to curl his fingers inside you, pressing his free hand to your stomach so everything intensifies as he picks up a steady pace. Then his hand shifts and his thumb presses against your clit, your hands immediately reach out, and you grab hold of the first thing you can. Your nails dig into his biceps as you hold on tight, feeling the muscle bulge and relax as he pushes towards release, the look in his eyes makes you want to give in to whatever he says.
There’s just something about him being fully clothed and fully in control, while you’re naked and at his mercy that makes the Omega in you purr appreciatively.
Your stomach tightens and your pussy flutters around his fingers as he pushes you towards your first orgasm. You’re breathing heavy and writhing beneath him when suddenly he pulls his fingers free, and your body slumps against the bed, with a sheen of sweat coating your skin. You whimper as you look up at him, wishing you felt a little less pathetic, because you would kick his ass if he was one of the Beta’s you’d slept with before. But this is an Alpha - your Alpha.
Dean chuckles, leaning back as he starts to pull off his clothes, and you can’t take your eyes off of him.
“Oh my beautiful Omega, don’t make all of those pretty little noises right now. I promise I’ll make it better. But the first time you come for me I want it to be with my cock inside you, stretching out this tight little cunt.” You moan at his filthy words as he throws his shirt across the room, he’s perfect, and you can’t stop staring, unable to believe how lucky you are.
“Please, Alpha. I need to come so bad, wanna feel your knot.” The desperation in your voice is clear as you cling to the sweat soaked duvet under you.
His eyes lock with yours as a filthy and cocky smirk curls at his lips. You watch with bated breath as he pulls off his jeans and boxers, and his thick cock is freed from its confines.
“Hmm, am I your first Alpha, sweetheart? Your only Alpha? Is this the first knot you’re gonna take in that perfect little pussy?” Dean sounds far too pleased with himself as he asks those questions, but in the moment they only make you squirm more.
He strokes his cock slowly in one hand as he pushes his other hand between your legs, and his thumb circles your clit torturously slow. You don’t want to stop looking at him, but your entire body is shaking with need. You clench your thighs around his hand, trying your best to stave off your orgasm.
“Dean, please. I can’t hold it,” you whine desperately.
To your relief his hand falls away, and you suck in a breath, feeling the heat of his body pressed against you forces you to open your eyes.
“You ready?” he asks quietly, voice husky and thick with need, and you feel the wide head of his cock pressing against your wet entrance.
You can feel his thighs quivering against your own, it’s pretty obvious he’s holding himself back. You meet his eyes and swallow hard, knowing that you couldn’t go back now, even if you wanted to. You need him, you can feel it deep down.
“Don’t you want me on my hands and knees, Alpha?” you ask, voice breathy, and you shiver feeling his fingers digging into your thighs.
“I’m trying to take it easy on you here, ‘mega, don’t push me,” his voice has lowered to a growl, and you know you’re poking the bear, but you can’t seem to stop yourself, you need him to lose control.
You slowly drag your hand down his chest and stomach, feeling the muscles ripple beneath your touch, and you hear him suck in a breath when your hand wraps around his thick length.
“I can take it, Alpha, want you to fuck me like you mean it.” Dean grunts as your hand moves over him and you turn your head to the side, showing him your perfectly clear skin, free of any scars and stroke your fingers down the side.
“When you claim me, right here-” you don’t get time to finish your sentence, because Dean has pulled out of your grip and his rough hands flip you over and force you on your stomach.
You barely have time to suck in a breath before he’s hauling you up by your hips. Dean spreads your legs and the head of his wide cock presses inside you slowly, but then his hips snap forward, and you scream in pleasure as you lose your balance. Your fingers curl around your pillow and your back arches painfully, as he pulls out almost all of the way and snaps his hips forward again. The grip on your hips tightens, to the point you’re sure there will be bruises left behind.
“How’s that, my needy little Omega?” he growls, wrapping his fingers in your hair and tugging your head back harshly. You can’t speak, you can hardly breathe.
“Ah fuck! Dean, please let me come!” you scream feeling your pussy spasm around his cock when he picks up a steady rhythm, deep and slow, and so hard you feel like your body is going to snap in half.
“Wait. I decide where I claim you, is that fucking clear?” he growls snapping his hips forward roughly.
“Fuck! Yes. Whatever you want, Alpha,” you whine obediently, impossibly close to the edge of a mind shattering orgasm. But even your body is refusing to disobey your Alpha.
“Mmm, good girl. C’mere,” he pants, tugging you back against him by your hair and nuzzling your neck. You don’t struggle, in fact, you find yourself relaxing against him.
“You wanna come all over my cock, sweetheart?”
“Yes. Please, Dean, I need it,” you whine breathlessly, feeling his free hand roam your body slowly, as he cock continues to thrust into you teasingly.
“Then play with your clit while I fuck you. I wanna watch you fall apart, my desperate little ‘mega.”
The sheets are soaked beneath you both, his rut and your heat are in full effect now, and you know you’d do anything he asked.
You drop your shaking hand between your legs and start to rub circles into your clit, feeling your pussy clamp down around his throbbing cock. You cry out when Dean starts to pick up his pace, his thrusts are precise, rubbing perfectly against your g-spot.
“Ah! Alpha, right there!” you practically scream as he roughly tugs your hair, pulling your head to the side, exposing your neck and you feel his teeth gently tug at your skin.
The threat of him claiming you is enough to send you hurtling into the most powerful orgasm of your life. Your body shakes in his arms as he continues to fuck into you, your tight wet heat gripping him like a vice. You’re vaguely aware of the fact that Dean’s wrapped an arm around your waist, keeping you pinned against him because you’ve gone limp in his arms.
“So sexy when you come ‘mega, such a perfect little pussy. You want it, baby girl? You want me to make you mine?” he grits out breathlessly. Your head is swimming as you feel another orgasm burning in your stomach, but his words are enough to make you moan in agreement. Dean chuckles, pushing the sweat soaked hair over one of your shoulders, “c’mon, ‘mega, need to hear you say it.”
You tilt your head to the side again and feel his tongue against your skin, “take me, claim me, Alpha. Wanna be yours.”
“Oh fuck,” he moans sucking hard at your neck, “gonna make me come ‘mega, gonna fill you up,” his voice is a broken rasp as he fucks up into you, his pace brutal.
He lets out an animalistic growl when his own release finally hits, and sinks his teeth into your neck, then you feel his knot swell inside you. His knot catches against your entrance as his cock pulses inside you, pulling another scream from you as your second orgasm shoots through your entire body. Gasping, you both crash down onto the mattress, with Dean’s body wrapped around you.
Your bodies shake against one another as Dean pulls his teeth carefully from your neck, and licks softly at his claim mark. Your heart is hammering in your chest as you take a deep shaky breath, as a feeling of being complete finally settles over you.
Dean presses kisses along your shoulder and brushes his fingers through your damp hair.
“Remind me to buy Sammy a house for bringing you to dinner,” Dean chuckles, his voice hoarse from your time together.
You giggle and lace your fingers with his, his hand feels so big against yours but it feels right.
“Just a house, huh?” you tease playfully.
He presses a soft kiss to your claim mark and he drags his teeth over your ear lobe, “mmm you’re right, maybe a mansion,” he whispers, every word punctuated with a soft kiss and roaming hands. You can’t help but be a little nervous, this is all so sudden. What if he changes his mind about you?
His cock slips free suddenly as his knot retracts, and he turns you in his arms, so that you’re facing him. The soft smile on his face is completely disarming, and you can’t help but smile back.
“I can practically hear you thinkin’, ‘mega. I promise we’re gonna figure all of this out.”
You sigh softly and lean in, kissing him for the first time in what feels like forever. When you pull away his intense green eyes meet yours.
“It doesn’t make any sense, but I trust you, Dean. You and me, it just feels right,” you tell him, and the emotion you’re feeling causes your voice to catch a little.
“That’s because it is. So, what do you say we get ourselves ready and go down to see everyone?, I think we have a little explaining to do, my beautiful Omega,” he whispers tenderly, cupping your cheek and presses a lingering kiss to your lips.
“Probably a good idea, Alpha,” you agree, feeling a blush come to your cheeks as your fingers graze over the claim mark on your neck. You weren’t expecting your life to change so drastically in a day, but you wouldn’t change it for the world.
