A/N: Helloooo, it's been a minute. If I'm being honest, I have about 10-15 finished works just sitting in my "ready to post" folder, but posting is always such an ordeal, so they just stay there until I feel like dealing with Tumblr. But, this one I did write over the last two days after I finished reading Bride by Ali Hazelwood, which I loved so much that it made me want to dip my toes into the Omegaverse! That being said, I don't know how much in here is actually in line with A/B/O "rules", but I know I needed to twist some things to fit the story (e.g. in this specific A/B/O fic/universe, claiming marks will fade if they're not true mates). Huge thank you to my A/B/O girlies, @makeadealwithdean and @emoryhemsworth, for reading it over, I love you both to the moon and back! I hope you all enjoy!

DEAN WINCHESTER MASTERLIST | SUPERNATURAL MASTERLIST | MAIN MASTERLIST
“We get in, find the knife, get out, got it?” Dean asks, looking between Sam in the front seat and Y/N in the back, making sure everyone is on the same page. They both nod once in understanding, before the three of them make their way out of the car, their doors slamming shut simultaneously.
Y/N stares up at the mansion before them, the music loud, the party raging. It’s some charity event thrown by the wealthiest Alpha in the state, and he just happens to have the weapon they need to finish out this hunt. Y/N stumbles a bit, tripping over the cobblestone driveway in her heels, and she catches the sleeve of Dean’s suit to steady herself. He shoots her a glare that tells her to pull it together. They need to blend in.
“Sorry,” she whispers.
“Here,” Dean replies, grabbing her wrist and pulling it through the crook formed by his bent elbow, forcing them to walk arm-in-arm.
“I don’t need –”
“You are an Omega, Y/N. And there are upwards of a hundred Alphas here who can all smell it. So what you need to do is start acting like one. Just because I’m not some asshole Alpha who demands your respect doesn’t mean they aren’t, and we can’t risk drawing attention to ourselves.”
Y/N takes a deep breath and plasters on a fake smile as they move slowly up the driveway. “Anyone who demands my respect just because of some bullshit biological hierarchy doesn’t deserve it,” she grits out.
Dean stops, turning to face her, one of his hands on either side of her biceps. “Do you want to be on this case or not?”
His voice is lower than usual, demanding and gruff. A voice he only uses when he wants to remind her that he is an Alpha, and bullshit biological hierarchy aside, her body is wired to listen to him.
She gulps, and he tries not to focus on the bob in her throat, the pulse in her neck near her gland, the scent of her. The moment he met her he knew who she was, what they were. Are. He’s been taking scent blockers since before he met her, finding it far easier to interact with other Alphas when investigating cases if they couldn’t scent him out, but the moment he met her, he knew he had to start taking rut blockers too. Though, it feels like the longer he’s around her, the more immune he becomes to the pills. Like she’s going to send him into a rut any fucking second, and she has no idea. He’s thought about telling her so many times, but mates come with strings. Strings that aren’t conducive to the life of a hunter.
“Yes,” she answers his question meekly, almost submissively, and he nods to cover the hormones he forces himself to swallow down. Rejecting your biology is not easy, no matter how many pills you take.
“Then I’m going to need you to take my arm, put on a smile, and act like being an Omega is the greatest joy of your life. That means –”
“I know how to be a good little Omega, Dean,” she interrupts, dragging the words ‘good little Omega’ through a sarcastic tone.
He tenses slightly at her words, sarcastic or not. Good little Omega.
“I’m only bad for you,” she continues with a cheeky wink, and fuck, he might explode. Hell, he might take her into the bushes right now and mark her, claim her, before parading her around in front of this entire fucking party with his teeth marks on her neck. He’s rigid, trying to keep himself under control, and she gives him a playful pat on his shoulder. “Lighten up, Alpha,” she teases. “I’ll be a good girl.”
Jesus fucking Christ. He gives her biceps a squeeze that he hopes comes off as reassuring as he’s trying to make it seem, before linking his arm with hers once more and catching up to Sam at the front of the driveway.
The trio is greeted by the owner of the mansion himself, one Jim Myers, who welcomes them in with a smile on his face and a cigar in his hand.
“How Gatsby-esque,” Y/N mutters under her breath, watching as Myers shakes Sam’s hand.
Dean nods in agreement. “You definitely wore the right outfit.”
Y/N blushes as she looks down at her dress; a black, semi body-hugging cocktail dress bedazzled with gold sequins in some sort of art deco pattern. All she’s missing is a cigarette holder and a feather in her hair.
“Only because I read the invitation. Unlike some of us,” she mumbles in reply.
“Watch it, Omega,” Dean grits out, plastering on a smile as soon as Myers comes over to greet him.
“Jim Myers, pleasure,” he says, shaking Dean’s hand.
“Dean. And this is Y/N.”
She keeps the cordial smile on her face as Jim takes her hand and brings it to his lips, kissing it gently before inhaling her scent.
“Pleasure, Miss Y/N,” he says with a feral grin, his eyes darkening with unmistakable lust as he lets her hand fall back to her side.
Dean takes a step forward, unable to stop himself. “Mine,” he practically growls, and Jim takes a step back, throwing his hands up in surrender.
“My apologies. I didn’t see a mark, so I just assumed.”
Dean falters, clearing his throat, suddenly reminded of the reason they’re all here in the first place. “No, that’s alright. It’s my fault for not putting it in a visible place.” His eyes dart over to Y/N’s. “I think I’m gonna fix that.”
She ducks her head but can’t hide the red flush that creeps up into her cheeks, reminding herself that it’s just her biology, and that this is all for show anyway. They’re here to do a job, and sometimes those jobs involve… well, whatever the hell just happened. And clearly, Dean is a better actor than she gives him credit for.
Jim chuckles, clasping his hands together. “Well, you three have fun, the drinks are free, the food is good, and if you,” he points at Sam, “good sir, are in search of an Omega, there are plenty to choose from.”
Sam blushes. “Right.” He nods. “Thanks.”
And with that, Jim disappears into the crowd.
“I’ll keep an eye on him,” Sam says. “You two go. Upstairs, down the hall, third door on the right. If I got the right blueprints.”
“If you got the right blueprints?” Dean asks.
“Just go.” He taps his ear to indicate that he’ll drop in on Dean’s earpiece if anything goes wrong.
Dean sighs, taking Y/N by the hand and leading her up the stairs. He weaves in and out of the crowd, the scents of everyone mixing together, making it impossible to decipher who is what. Y/N’s never been more glad to be on heat suppressors; knowing full well the scents of this many Alphas invading her nostrils would send her body into a major one.
Dean quickly finds the door, and they slip into the room unnoticed, closing the barrier and switching on the light. It’s a bedroom — the master, from the looks of it — and the knife is right in front of them in the middle of the room, across from the foot of the bed. It’s in a glass case, on display, and likely armed with a million alarms, but right in front of them nonetheless.
“Son of a bitch,” Dean mutters, running a hand through his hair as he thinks about what the next move should be.
“We could find something that weighs the same? Lift the glass and replace it super fast?” Y/N offers.
“Unfortunately, I think it’s the glass that’s probably set to trip an alarm. But the fact that you’re applying Indiana Jones to real life scenarios is making me want to —”
He stops himself, realizing what he was about to say. He needs to get himself under control but Y/N in that dress with her smart fucking mouth, with other Alphas eyeing her, he really shouldn’t be here, with her, alone, and —
“Making you want to what?” she asks.
Shit. “Making me want to… make you watch more of them,” he replies, opting to circle the display case, searching it for a way in to distract himself from her.
“Oh, goody. Can’t wait.” She’s as monotone and sarcastic as ever, and every time something smart comes out of her mouth he has to resist the urge to bend her over and fuck her right then.
“Get out of there now,” Sam’s voice comes in on Dean’s earpiece. “Lost track of him for a few seconds, just found him again. He’s making his way upstairs.”
“Shit,” Dean says. “Shit, shit, shit.” He looks around the room frantically. If they go out the door, Myers will without a doubt see them leaving his room. “Myers is coming,” he explains to a confused-looking Y/N.
“Fucking — God dammit.” She looks around too, for a hiding spot, for a weapon, and then she spots herself in the mirror hanging on the wall and an idea comes to her. “Mark me,” she orders.
“What?” Dean snaps, his attention fully on her.
“Get over here and mark me. You told him you were going to make it visible.” She continues before Dean can protest. “Who knows if it’ll even stay, it’s not like we’re mates, right? And if it does, I don’t mind being bound to you for the rest of ever. It’s not like I’m having much luck in the relationship department anyway. But we need that knife, and we’re not going to get it if we don’t –”
“Fuck,” he says under his breath with a quick shake of his head, before he strides across the room and pushes her up against the wall just in time to hear the door click. He inhales her scent, his mouth trailing from the base of her jaw all the way down to her mating gland where it hovers as the door opens all the way. Then he bites down.
Y/N throws her head back, her fingers digging into Dean’s shoulders as his teeth sink into her, and none of it is for show. The pain is euphoric, and her senses heighten, and she suddenly wishes she hadn’t been so stringent on taking her fucking pills, because whatever this feeling is, coursing through her veins, settling in her core, she needs to feel it more. She can’t stand how dulled it is, how it just stays there, simmering underneath the surface. She wants to erupt.
“Mm, fuck, Alpha!” she cries out, no trace of sarcasm in her voice, and Dean’s hands grip her hips tight enough to bruise them.
“Oh, I’m so sorry!” Jim exclaims. “Got an alert that someone was in here, there’s some very valuable things in here, you see, and I just wanted to make sure —”
Dean pulls away from her neck long enough to shoot him a glare that translates to “get out or I’m going to kill you”, and Jim gets the message, backing out the door and shutting it behind him.
“Fuck,” Dean breathes, letting his forehead fall to Y/N’s shoulder. He shouldn’t be so close to her. He should back away, give himself some space to breathe. But her scent keeps him rooted in place. It’s her usual scent; something like freshly baked sugar cookies and vanilla, sweet and enticing, but there’s something else, something —
“Are you guys okay?” Sam’s voice in his damn ear again.
Dean lifts his head and presses the button on his earpiece to reply. “Fine, Sam. Give us a second.” Then he takes the earpiece out and tosses it over his shoulder, more agitated than he should be at his brother just trying to check in.
“Dean,” she breathes, and she sounds absolutely wrecked. She brings her hands to his cheeks, forcing him to look at her. “Are you okay?”
He nods. Her touch is like fire on his skin. He needs her.
Y/N squeezes her thighs together. She’s never been able to scent Dean before, but he’s never been this close for this long. He’s never marked her, either. Right now his scent is breaking through the suppressants, little by little. It’s bits of cedar and leather and whiskey, and she’s never smelt anything like it, yet it is so familiar somehow. It invades her senses, and if this is what he smells like with suppressants, she’s terrified of what would happen without them.
“Dean… your scent.” She closes her eyes and inhales deeply.
“Fuck, my pills must’ve worn off, I —”
She shakes her head. “It’s dulled but… but it’s there.” Her thighs clench together again, and she needs him back on her skin. “It’s there and it’s so fucking good.”
Dean’s eyes fall to the gland on her neck, and the severity of what he’s done comes crashing into him like a wrecking ball. It’s enough to force him to take a step away from her, panic rising in his chest. “I – fuck. I marked you. I fucking marked you.”
Y/N’s fingers come up to graze the indent on her neck, and she shudders at the touch. “I told you to.”
“No, you don’t understand, Y/N –”
“I know what happens when mates get marked, Dean,” she interrupts matter-of-factly. “I’m sure this’ll fade.”
“It won’t. I – I shouldn’t have done that. Fuck. Fuck!” He turns to the wall next to him, hitting it with the side of his closed fist.
“Dean.” Her touch on his arm is gentle and comforting, but he doesn’t turn to face her. “You need to calm down. It’s really not a big deal, I –”
Dean takes a deep breath, both hands on the wall now as he collects himself. He can’t even bring himself to look at her when he says, “You’re my mate, Y/N.”
She takes a step back, and her fading scent is what makes him finally face her. She’s halfway across the room by the time he does.
“W-what do you mean?”
“You’re my mate, Y/N,” he repeats.
She shakes her head, her hand coming to her neck again, the teeth marks seared into her skin. “N-no. H-how? When? How – how long have you known?”
Dean takes another long, deep breath. He could lose her tonight. She could run and never come back and he wouldn’t blame her. “Since we met.”
“THREE YEARS!?” she roars. “YOU’VE KNOWN FOR THREE FUCKING YEARS!?”
“Y/N, I –”
She stalks toward him, one finger outstretched, one fist clenched by her side. She points at him as she backs him into a wall, and he’s incredibly turned on and incredibly scared at the same time.
“You’ve known that we’re fucking mates for three years, and you didn’t feel as though that was pertinent fucking information to tell me!?”
Dean swallows. “I – it’s – there are… strings with mates. You know that. I didn’t want to ball and chain you. I didn’t want to keep you anywhere you didn’t want to be. And if – fuck – we’re hunters, Y/N. If something had happened to me, and you knew… I didn’t want you to have to live with that. With the pain that comes with losing a true mate.”
Y/N stops half a foot away and drops her accusatory finger. “What did you say?” she whispers.
“True… mates,” Dean breathes.
“We’re…? But… We never – I don’t –”
“With me on my pills, and you on your pills, I think it was enough to… so we just never…”
“But you knew,” she says, closing the gap between them, her hand coming up to caress his cheek. “You knew for so long and you watched me go on dates, had to listen about the… things I did with other Alphas… if I had mated with one of them, you –”
“You deserved to have a choice. Regardless of what I wanted, you deserved to have a choice.”
“My choice could’ve left you depressed and alone and celibate forever, you fucking dumbass.”
He shrugs, and her hand falls to rest over his heart. She stares at it as she continues.
“When you… marked me… I felt… I don’t know what I felt. Nothing’s ever been so intense.”
She looks up at him through her eyelashes, and he smiles softly.
“That’s the bond,” he explains, his large palm coming to rest over the hand on his chest.
“And if we weren’t on… our blockers?”
“If we weren’t on our blockers, there’s no fucking telling how many pups we’d have running around by now.”
Y/N shivers as the thought of being bred settles in her core, and for once she’s not cursing her biology. Dean chuckles faintly at her reaction, dropping his forehead to hers.
“We can practice in the meantime. Until you decide you want off of them.”
She inhales deeply, taking in as much of his scent as she can. “Oh, I –” another deep breath, “I’m getting off of them for sure.”
Dean lets out a borderline animalistic growl, thinking about how many times he’ll get to fuck her through that first heat. “I’m gonna stop taking my pills, too,” he says breathily.
“Yeah?”
“I had to get on rut blockers when you moved into the Bunker because I knew I wouldn’t be able to control myself. But now,” he says, spinning them both around and pinning Y/N against the wall, “now I don’t fuckin’ have to.”
“Dean,” she half gasps, half moans. He kisses the mark on her neck before licking all the way up to her jaw line and pulling back.
“You drive me fuckin’ crazy, Omega.”
She meets his feral gaze with one of her own, a glint of mischief in her eyes. “Prove it.”
And it might be an incredibly stupid thing to say to a horny Alpha, but it’s also Dean. And he’d never hurt her.
“Mm, fuck.” His voice is raspy and wrecked and they haven’t even done anything yet. Before Y/N can process what’s happening, he’s picking her up and throwing her onto the bed. He climbs over her, hovering for a moment, taking in her flushed cheeks, the warmth radiating off of her, her scent. “You’re beautiful,” he states plainly, like it’s the one fact in the world that he knows without a doubt to be true.
Y/N blushes. “Thank you, Alpha.” She says it because she knows what it does to him.
“You’re beautiful, and I’m gonna fuckin’ ruin you.”
A gasp leaves her lips as he pushes her dress up her hips and moves down her body to the foot of the mattress, his fingertips dancing along the hem of her panties before his eyes meet with hers. She gives him a nod, and it’s all the confirmation he needs before pulling them down her legs and tossing them aside.
He watches hungrily as she spreads her thighs, her core damn near dripping with her wetness, and if this is what it’s like when she’s on heat blockers, he can’t even begin to imagine what it’ll look like covered in her slick. His cock grows hard in his slacks at the thought, and he has to step off the bed to take off his pants and boxers before the containment grows painful. He shrugs off his suit jacket and white dress shirt too, and when he’s standing in front of the bed, fully naked, Y/N is propping herself up on her elbows to take him in.
“Holy – fuck,” is all she can get out.
Dean chuckles deeply, one knee coming up onto the mattress as he fists his cock. “Fuck, sweetheart.” He looks her over again, pussy glistening, nipples peaked through her dress. “Fuck, I want you to – would you present for me?”
A smirk spreads across her lips, but she doesn’t say anything before flipping over and assuming the position. Ass up, legs shoulder width apart, chest resting on the mattress.
Dean lets out a low and guttural, “Fuuuuck,” and it’s enough to make her pussy clench around nothing. She feels the mattress dip behind her, and when his cock starts to move through her folds, she almost cums right then and there.
“I know you you wish you weren’t an Omega,” he starts, “but you’re a fuckin’ perfect one, baby.”
She shakes her head, soft whimpers escaping her as he continues to tease her with his dick. “I’m glad I’m an Omega, because I’m yours.”
With that, Dean loses what little self control he has left. He lines himself up with her entrance and sinks into her heat, and she feels so fucking perfect, the way she molds around his cock. The noises leaving her throat spur him on as he thrusts into her, setting a bruising pace. He wraps his hand around her shoulder for leverage, his other gripping her ass.
“Oh my fuck!” she practically screams, and he can feel how close she is, can smell it.
“You’re gonna be a good little Omega and cum for me, aren’t you baby?” he pants, and he couldn’t be thrusting deeper if he tried.
She nods frantically. “Yesyesyes, please, Alpha, I wanna to cum. I wanna — mm, fuck — on your —”
She’s too fucked out to even finish her sentence, and Dean can feel himself about to fall over the edge. “What’s that, sweetheart? Speak up.”
“I wanna cum — oh, God! — on your knot. Fucking fill me up, Dean, please.”
He barely manages another thrust before he buries himself to the hilt, the base of his cock swelling inside her as he pumps her full of his seed.
The feeling of him filling her sends her over the edge, her pussy clenching around his cock, his knot, and she feels so full and fucked and sated.
“Oh my fucking fuuuuck,” he groans, feeling her pulse around him. “Fuck, everyone and this fuckin’ party is gonna be able to smell me inside of you.”
She moans at his words.
“Gonna have me dripping down your thighs ‘til we get back home.” His hand squeezes the globe of her ass before he leans over, getting as close to her ear as he can. “And then I’m gonna fuck you again. And again. And again. Because we got three years to make up for.” He nips at her ear playfully. “And now you’re finally mine.”

⋆.˚ ᡣ𐭩 ⏖ 'make me' with skz !
⁺ 𖹭 . genre: this is very suggestive lmao
⁺ 𖹭 . a/n: this is a repost from my old blog! so if you feel like you've read this before, that's why :)
𝜗୧ chan 𝜗୧
“Make you? Make you do what?” yes, he will play dumb to ‘make you’ use your words and elaborate.
Doesn’t do anything and acts oblivious until you actually say it, no matter how much he wants to.
Acts bubbly and normal like nothing even happened, laughing away without a care in the world while watching tiktoks or something. Unbothered.
The moment you do speak, something inside him snaps and he’s got you backed against a wall in moments, talking lowly over your lips while caressing your face.
𝜗୧ minho 𝜗୧
Oh, he will. No matter the context or where you are, Minho will take your words as a challenge and do anything in his power to make you regret ever doubting him.
Gives you this specific look that makes you go weak in the knees, raising a single eyebrow before beckoning you closer.
Will whisper in your ear, giving you one more chance to back down while softly playing with a strand of your hair.
If you don’t do as he says, he will start whispering the dirtiest stuff with the straightest face, being content with just flustering you until you get home and he can finally ‘make you’.
𝜗୧ changbin 𝜗୧
Forget about teasing and playing dumb, Changbin will ‘make you’ instantly. He doesn’t play around.
Will also back you up against the nearest surface and cup your face, resting his forehead on yours with a smirk on his face.
He feels so smug and cocky when he sees you get shy and regret your words that he can’t help but find the whole situation amusing.
The power imbalance the moment provides feeds his ego so don’t expect to get away with this scot-free. Changbin will punish you thoroughly.
𝜗୧ hyunjin 𝜗୧
Raises an eyebrow and just…stares at you, blinking. Looks so unphased that you actually think he didn’t hear you at first.
But he did, and the moment you repeat yourself, he stands up to tower over you, fisting some of your hair in a makeshift ponytail to bring your face closer to his.
Licks his lips just to torture you a little more before finally pressing them to yours for a needy kiss, the soft action a straight contrast from the hold he still had on your hair.
When he pulls away, he repeats the words that got such an answer from you and expects you to finally listen, eyes sharp without any hint of playfulness in them.
𝜗୧ jisung 𝜗୧
Turns red instantly and his brain kind of short-circuits because he wasn’t really expecting that.
If this was said in the heat of the moment during an argument, all of the anger will leave his body and he will just…stand there, flustered.
His mind will be racing with all of the things he wants to do to you, some innocent, others not so much while he looks at you, licking his lips.
Jisung will be tongue-tied, wanting to say too many things at once so you have to be the one pulling him from his trance if you want something to happen.
𝜗୧ felix 𝜗୧
Felix will get the biggest smirk on his face, I swear. These are two of his favorite words after all.
He will make you do things you’ve never even dreamt of doing so be careful what you wish for.
Takes a hold of your hand and draws you closer until you’re a breath away, placing a sweet peck on your lips that somehow leaves you dizzy and desperate for more.
Then, his voice drops and you feel the vibration in your bones as he speaks. “Make you do what exactly? Tell me, in detail.”
𝜗୧ seungmin 𝜗୧
Oh, you want him to make you shut up? Say no more.
Will get up and actually go through all the trouble of getting a paper towel and shoving it in your mouth Minho style (I AM SO SORRY KSJDGNDF BUT HE WOULD)
That is if he isn’t in the mood to play your games. If he is, however, things would be completely different.
“Are you sure this is what you want? You might end up regretting it.”
𝜗୧ jeongin 𝜗୧
A tease from beginning to end. He won’t take you seriously at all I’m afraid.
Might even laugh in your face before making himself more comfortable in his seat, (man)spreading his legs before beckoning you closer with a single finger, amused.
Wants you to entertain him and if you don’t, he will ‘make you’.
Will place you in his lap and use his words to fluster you beyond belief, his fingertips ghosting over your skin sending shivers down your spine.
