Work Text:
Yoo Joonghyuk is currently in a relationship with Kim Dokja, he is by all accounts a full fledged beta, he hails from a long linage of betas and the occasional alphas, he's sure there's not a single trace of omegan ancestry in his blood.
Kim Dokja also happens to hail from a typical beta family, but someway, somehow, during the scenarios, he became an alpha. That isn't something too farfetched, it certainly wouldn't be the first time he's seen someone went through a presentation again, the combination of stress and the new leadership position he had might have been a trigger.
They're an atypical couple sure, but it's not like alphas can only date omegas and vice versa, however there's a reason why alpha-omega pairs are more likely to form long standing bonds, and one show of their incompatibility, especially, is currently glaring him straight in his face.
'Hyunmin-ssi is just being friendly, he's like this with everyone else really I swear.'
Oh really, so your colleague just scents everyone around the office willy nilly till the point where they reek of his omega pheromones.
Alphas and omegas have special constitutions, one being a heightened sensitivity to scents, the other producing higher concentrations of pheromones, both of which is tailor-made to help find their ideal mate. Joonghyuk can see the redness in Dokja's eyes, he's affected by the scent of an unfamiliar omega, but was probably too nice to just give an outright refusal.
Hyunmin, that asshole who's always sneaking glances at Dokja, like we wouldn't notice.
A fucking wedding ring isn't enough to get that bitch to know his place, clearly.
'I'll take a shower then, don't over think it, we just finished a huge project, everyone was in high spirits, it's just that he was... more enthusiastic .'
Yoo Joonghyuk feels like he could taste the cinnamon if he so much as sticks his tongue out, the moment Dokja sheds his clothing he throws all of it into the washing machine, wasting water be damned. He's not letting that fucker's smell linger in his house, in their house. Growling low in his throat, he rummages through the rest of Dokja's work clothes, re-scenting every single last one of it, he knows all of it will fade away before breakfast tomorrow, he doesn't fucking care because that's just how frustrated he's feeling right now. His beta pheromones could last 4 hours, 7 at most, whilst Dokja's alpha ones wouldn't disappear from his clothes for at least 2 days.
That fucking bastard had the audacity to scent mark my mate, my married bonded mate and thinks he can get away with it. That son of a bitch!
Putting the clothes back onto the hangers, he hears the water from the showers go off, Joonghyuk is not happy at all, and he's going to make that point vehemently clear. Dokja doesn't even get one foot outside the bathroom door before he's dragged sputtering to the bed.
'Hey! Easy, if you wanted to do it, you should've told- mmph-'
Dokja doesn't get another chance to speak, his mouth muffled by a forceful kiss from Joonghyuk, and he's not in the mood to be slow tonight, breaking away with a gasp he reaches for the lube on the nightstand. Squeezing a generous amount onto his fingers, Joonghyuk sticks one inside Dokja without waiting for it to warm up, garnering a wince from the alpha. It's not the first time the beta has taken the man in such a manner, but usually he has enough consideration to properly stretch his partners' hole, with his size and the fact alpha's are just naturally tighter down there, it's practically a requirement for it to be enjoyable.
'Hah-Slow down, Joonghyuk-ah it hurts...'
'Grrr...'
Despite his obvious displeasure, Joonghyuk does lessen his pace, though he doesn't let up on the rest of his actions. He bites and gnaws at every part of exposed flesh he can reach, trying to imbue his scent and marks onto the alpha, he'll see whether or not Hyunmin gets the hint when Dokja goes to work covered in hickeys tomorrow.
'Ouch! Hyuk what's with you, I still need to go to work next day you know.'
'Hmph that's the fucking point! If I can't scent mark you, then I'm going to use every method available to make it clear that you are mine! That you, Kim Dokja, is off limits!'
Joonghyuk snarls at the thought of anyone getting intimate with his alpha, Dokja was his and only his, nobody, especially not some random omega from his office is taking his alpha away. He fits the third finger inside, stretching the rim out even farther, making the alpha groan.
'Fuck, something tells me I might not be able to- ahhh- to walk tomorrow.'
'Why did you come back reeking of that bitch. You're not that dumb, I know you aren't! So why? Why did you let him scent you!'
'I promise it was just because of the celebration party, otherwise he wouldn't even have the chance to get within 5 metres of me.'
'He still got his scent all over you, do you have any idea how it feels? To have your mate come back to you smelling of another person's pheromones!'
'Joonghyuk-ah, I swore to you my love and trust till death do us part, I would never leave you for anyone else, not a beta, an alpha or an omega. You are all I could ever want and all that I need, you know that.'
That doesn't make things any better.
Why did he have to attract an omega of all people, why an omega specifically. Why?!
Joonghyuk could feel the sides of his eyes heat up, he would not cry, not at a time like this, not over some nobody that- that-
'Joonghyuk-ah, open your eyes.'
Dokja is looking up at him so tenderly, gently thumbing away the hot tears that have begun to fall, Joonghyuk doesn't understand, why is he crying. He's mad, he not supposed to be sad, all of this is supposed to be resolved after he fucks Dokja within an inch of his life, why is he sobbing like a omega rejected by his alpha.
Because you wished that it was you, you're jealous.
Jealous because you know that an omega will always be the natural pairing for an alpha, a beta like you only get odd looks no matter where you go.
An omega could properly scent their alpha, not like you whose scent can hardly linger on his body every day.
Because you are everything an omega isn't, and nothing an alpha would ever need.
'Joonghyuk! Husband, please come back to me. Wake up, this isn't one of your regressions anymore, wake up Joonghyuk-ah.'
Joonghyuk was clinging onto Dokja, he could feel how fast his heart is beating inside his chest, how his breaths come out irregular and sporadic, it feels like he would die if he lets go. He doesn't ever want to let go, he wants to stay in his alpha's arms forever, he wants him to keep saying those sweet words of his, more and more until he drowns in it, to bask in his scent until he doesn't even know where the start of Dokja and his scent began. Eventually, Joonghyuk calms down enough to talk, as though trying to coax him Dokja leaves pecks around his face, making him hard again embarrassingly quickly.
'If you keep doing that, I can promise you you'll definitely not be walking tomorrow.'
'Hahaha, I was just trying to get you to relax, how could you get aroused by that.'
'Because it's you doing it, Kim Dokja.'
That earns him a rare blush on Dokja's face, but Joonghyuk could tell from the look in his eye that he's not the only one affected, he's just the one openly showing it. Leaning in, he captures those soft lips that he could never seem to get enough of, using his wrist to leave his scent on Dokja's primary gland, the one which bears his mark.
'God if you keep doing that, I can't promise you won't be the one incapable of leaving the bed tomorrow.'
'Is it really that much of a turn on?'
'Yes Joonghyuk, you have no idea.'
And Joonghyuk doesn't, he feels the bond that ties them together when he touches his mark, but he really never got the euphoric sensation Dokja talks about whenever he touches his alpha’s scent glands. But he doesn't doubt it's an exaggeration, after all, Dokja's rapidly rising dick is a clear indication of the truth.
Too bad, I'm not in the mood for receiving today.
With a swift movement, Joonghyuk has Dokja pinned back down on the bed, provoking a growl from the back of the alpha's throat as his eyes glow golden from the act. He knows Dokja never means any of it, it's purely instinctual, just like how his beta cowers slightly at the intimidation, it only takes a while for both of them to suppress those base instincts of theirs.
Otherwise, I don't think I'll be able to tolerate just getting railed by Dokja for the rest of my life, no matter how good it feels.
Putting his fingers back up Dokja's ass, he's pleasantly surprised it's still as loose as before, making it easier to continue where they left off. Soft whines and the occasional moan only serves to encourage Joonghyuk's actions, only when he's sure he wouldn't draw blood does he enter.
Lining up his hard dick, he slowly eases his way inside Dokja, he physically pains him to take it this slow but he has to, at least initially. He could see Dokja's eyes fluctuating between gold and black, his lips drawn back into a half snarl, he's trying his best to suppress his alpha, to keep himself from lashing out. Even after their bonding, this happens occasionally, enough times that Joonghyuk has learned to pay extra attention at the start. Not that Dokja's alpha could stop him, but it makes both of them feel better if one is allowed to adapt first.
That's another thing biology messed them up on, alphas are born used to being in the dominant one, getting them to accept anything else is a challenge. Thankfully, Kim Dokja was a beta for most of his life, it's possible to learn how to suppress his alpha.
'You can move now, it won't act up anymore.'
Joonghyuk doesn't spare any delays, and started thrusting in earnest, moaning at that familiar feeling of Dokja's tight heat, he has to use so much more lube to get it to open up but it's worth every last bit of it. Dokja lifts his hips up, legs circling around his waist, and Joonghyuk kissed him like it was his last, desperate and sloppy, the bed creaking from his vigorous movements.
Joonghyuk squeezes the base of Dokja's cock, simulating the feel of an omega's cunt, he wants to empty out every last drop of cum from his alpha's balls, get the scent of his alpha all over him and what better way than to get him to knot.
'Mmph- stop- mmh- Joonghyuk! You're gonna make- ah~ a-a mess...'
‘The sheets are getting washed tomorrow anyways, let me make a mess then.’
Dokja weakly voices out his protest, yet his body can't help but buck into Joonghyuk's hand, wanting nothing more than to come, to feel the sheer ecstasy that only knotting could provide. Joonghyuk takes full advantage of that, stroking the rest of Dokja's cock as he fucks himself deeper and faster inside the alpha's ass.
'Feel so good Dokja, squeezing around me so nice and tight, you should've been an omega with how pretty you look having my dick up your ass.'
'Ahh~ Hyuk...'
It's not everyday Joonghyuk feels like playing alpha, just like Dokja doesn't always like playing omega, but sometimes when the stars line up just right.
If Dokja was an omega, I'd be fucking him seven days a week.
A bashful but taunting expression appeared on Dokja's face, and Joonghyuk knew from that that it's one of those days for him.
'What huh? You gonna breed me, alpha~'
Fuck!
Joonghyuk looses himself further into that pliant wet heat, his mind conjuring up all the delusions he's used to seeing whenever he gets riled up like this. Dokja building a nest, Dokja round with their child, Dokja getting softer after the childbirth, and him, Joonghyuk, holding their newborn child in his arms, feeling nothing but complete happiness as they look down on their bundle of joy.
Joonghyuk lets out a hoarse moan as he feels himself tipping over the edge, letting out all his pent up emotions as he rides out his high, feeling his own fluids leak out onto his thighs as he finishes.
'Close... Husband~ please let me come, please, I want- wanna knot, wanna-'
Whatever Dokja intended to say got cut off, as the knot inflated inside Joonghyuk's clamped fist, semen rushed out the tip of the alpha's dick, it never fails to amaze him just how much gets released with a knot compared to normal. He keeps his fist snug over the knot, and uses long slow strokes to ease out every spurt of cum that comes out of the top.
Ugh... this is going to suck to clean up tomorrow, but it's so damn hot.
Dokja had his eyes rolled to the back, his mouth wide open, his expression blown wide with pleasure as he gets milked for every last drop of his come. Joonghyuk read somewhere that knotting is the most satisfying act for an alpha to do, so he does indulge Dokja sometimes by letting him knot inside him, assuming he manages to even have it fit in the first place.
Having said that.
Joonghyuk looks at the wet mess all over the sides of their bodies and remembers just exactly why he rarely allows for it to happen, then he sees the glazed look of contentment on Dokja's face and decides that he'll leave this conversation for the next day.
Why haven't they invented condoms for alpha knots, seriously.
Joonghyuk had just enough energy left to lift Dokja over to the less messy side of the bed, he pulls the blanket over them and finally let his exhaustion take over.
