Work Text:
The content proposal comes as a surprise.
It’s a normal Tuesday full of long dance practices and corralling the pups through yet another album recording when A&R sits him and Riku down in their office, tells them that they’re going to guest star on the Return of Superman, and that their audience is going to love it.
It’s kind of a lot to take in, immediately, since Sion’s head is still running through 1-2-3-4-1-2-3-4-1-2-3-4. Their management team is reading off a list of shoot concepts, and Sion barely even hears them.
“Um, what?” Sion asks. Because he’s still stuck on their new song’s dance break and the way Sakuya’s leg has been acting up and- “Can you repeat that again?”
“You’re still young, but stats show that the fans want to see you two in the position of caretakers,” the main production noona says. “An alpha and an omega showing that they care for pups is expected to make a big impact, and the show proposed that in order to help with declining birth rates…”
Sion blinks.
The Return of Superman. The show meant to show alphas with their pups. The show that is full of pups being cute and alphas learning to do the tasks their omega mates do everyday, and all in all, is meant to fuel the innate urge in everyone’s secondary genders to procreate.
Sion and Riku. On that show.
Huh.
Kind of a weird thing for the two of them to be doing, quite honestly, considering both their age and their profession. But the appearance fee is good and it’s an exposure no-brainer. It’ll drive their fans crazy.
(It’ll drive Sion crazy.)
“It’s for a special episode,” she says. “Nothing too insane. The shoot’s in Yeoju. Just for a few hours, the kids aren’t used to being on camera anyway.”
Sion sends a sideways look to Riku, who isn’t saying much, but has that gleam in his eyes like he’s scheming something. Could just be excitement, or maybe he’s thinking about what prank he’ll pull on the maknaes today. Despite being Riku’s boyfriend and pseudo-mate, Sion still can’t really differentiate between the two.
They discuss the shoot some more and come to an agreement of stipulations. They agree to the appearance. They sign the contract.
Sion blinks, and all of a sudden he and Riku are being sent back to dance practice.
“Are you excited, hyung?” Riku asks. He’s smiling. They’re walking side-by-side down the hallways of SM, fingers brushing against each other. Nothing too overt. “We get to play with pups on TV!”
Sion is… well. His subconscious is still processing. Hearing the words Riku and pups in the same sentence makes him feel a very specific type of way that he’s unable to put into words. Or a very specific type of way that is too scary to put into words, something he’s too young and not ready for yet. His heartbeat feels a little off. Like it’s pounding too hard.
“Of course,” Sion says, despite the inner turmoil. He smiles back, takes Riku’s hand. “I’m excited to do anything with you, yeobo.”
It’s a good distraction, because as expected, Riku makes a face. Yanks his hand away, ears burning.
“You’re so gross!” He complains. He does not look Sion in the eyes. Instead, he picks up his pace, as if trying to put distance between the two of them. “God, you’re so bad at flirting, you’re lucky your face is so handsome.”
Sion grins. His inner alpha is humming nonstop, omega and pups, omega and pups, omega and pups. For some reason. He tries not to think about it.
“But honey~” Sion coos. “I just want to adore you~”
“Perverted old man!” Riku shrieks as Sion begins chasing after him. “Get away from me, you weirdo-!”
-
Sion’s head has been weird recently. He thinks it might be his upcoming cycle, but it’s hard to say. It gets even weirder when it comes to Riku.
But it’s not like that’s a new development, not really.
There are times, lately, where he just watches. Riku is playing with the pups, chasing them around the practice room. He’s been in a good mood, lately, which Sion is thankful for because they’ve been overworked and beyond stressed and it’s not unusual to see his mate go a few days without smiling, tired beyond belief. Especially since Riku’s been in and out of sickness, unable to properly rest or heal with their schedules. Sion’s been trying to dote on him, has been trying to keep his eye out, but of course the stubborn omega refuses to let him unless he’s struck with fever and begrudgingly letting Sion spoon-feed him miso soup.
(Maeda Riku isn’t the kind of omega who wants his alpha to provide, which sometimes drives Sion absolutely crazy, but ultimately is just one of the reasons he adores him so much anyway.)
Sion watches Ryo and Sakuya pile onto Riku’s back, and fights the urge to chastise. He should be happy that their pups are so high-energy despite the choreo they’ve been doing all day driving them all to the brink of insanity, but sometimes he just worries. They’re all fit, they’re all strong, but sometimes Riku looks frail. But then he’s shoving the other two off and scruffing them and making them sit down to drink water and Sion nags at his inner alpha: look at how strong our omega is. He doesn’t need it.
Hmph, his alpha says.
Maybe it really is just his cycle. He’s been more protective, more irritable. His idol image always comes first, so he doesn’t think most of the others have noticed properly, but both Yushi and Daeyoung have been giving him wary looks behind Riku’s back.
Daeyoung had even asked Sion if he was mad at him, for god’s sake, which Sion had beat himself up for. Daeyoung is still a pup, basically, and Sion had told him of course not, sorry, cycle’s being weird, you know how it is. Daeyoung had nodded but has still been more hesitant to engage with Riku in skinship, so Sion has had to keep himself on a short leash. Has had to suppress growls and paint a smile on his face when they take pictures for their socials and has had to pretend like it doesn’t bother him that other people can see Riku’s unmarked neck, even if he reeks of Sion once the scent patches come off.
The last thing their group needs is his secondary gender creating more tension, especially since one of the joys of Riku’s life is looking after the maknae line like he’s their dame. Which is another thought that has been driving Sion crazy, recently. Absolutely insane.
Ryo had made a joke, once, during a variety show. Sion hyung’s like our sire! He had said. Riku had laughed: Does that make me the dame? And Ryo said obviously, hyung.
Sion had laughed along when it happened, and he’s not even sure if that conversation even made it into the final edit, but it’s been haunting him. That particular line of thinking is like an itch he can’t scratch. Riku, as his mate, as his pups’ dame, as-
Well. Anyway. It’s something he can’t afford to think too hard about.
“You have that look on your face,” Yushi says. He’s got his head in Sion’s lap, playing on his phone. He’s been touchy, recently, and Sion thinks it might be the stress. “You look like you’re about to make a bad decision.”
Sion stares down at him. “What are you talking about?” He asks, though he has a feeling that he knows anyway.
Yushi shrugs. Smiles to himself. “You’re the one being stupid, not me.”
Sion presses his lips into a thin line. Hard to argue against that.
He’s trying his best to not be too... much. After all, Riku doesn’t need it. The pups certainly don’t need to see him be jealous, or possessive, or anything of the sort. And god forbid he gives Yushi any more ammunition to give him that gaze that says I know exactly what you’re thinking, and I am severely disappointed with the fact that you think with your knot more often than you think with your brain.
And Sion’s been good about it, he has. But the cycle’s been weird, his suppressants have been giving him oddly emotional side effects, and his rut usually comes early or late or not at all. It’s been a nightmare to plan for the past few months, ever since they started promoting more in Korea instead of Japan and work’s been a nonstop stream of practice-variety-music show-recording-practice-filming-MV shoot-music show. Usually the possessiveness starts happening before he even realizes that he’s in that part of his cycle, and if he’s not ready for it, it’s nearly impossible for him to control.
(One time Sion had been in pre-rut and had snapped when an alpha from another group got too close. His alpha had roared at him until he had dragged Riku to an empty closet, had stuffed his cunt full, had made him perform like that. And then ate it out of him later, and then the rut quickly took over from there.)
(So, okay, maybe he’s prone to possessive tendencies. But it’s his cycle, okay? He swears.)
“Sometimes I’m just amazed that Riku’s got you wrapped around his finger, is all,” Yushi says. “It’s funny to watch.”
Sion’s alpha wants to growl at that, but he doesn’t. It’s the truth, anyways. Sion behaves because he’s their leader and their hyung and because Riku could find a much better behaved alpha if he didn’t. And the last thing he needs is for Riku to decide that he’d prefer an alpha with better control over their jealousy.
“I don’t know what you’re talking about,” Sion says in a flat voice. Yushi grins.
“It’s okay to be whipped, hyung,” he says. “I know you can’t help it.”
Sion rolls his eyes, shoves him off his lap. When did his members start being such know-it-alls?
-
“You look tired,” Riku says that night, while they’re in their nest. He latches onto Sion, arms around his neck, head buried in his shoulder. “My hyung works so hard, hmm?”
Sion has to suppress a grin, as he always does when Riku decides to be sweet to him. Because no matter how much his mate raves about his good looks and stellar leadership, getting Riku to drop the brattiness is still a work in progress.
“You think so?” Sion asks. He nuzzles Riku closer. “Guess it’s because my omega’s expecting me to. Gotta show off for him.”
They both know that’s a lie, and they’re both just overly committed to their jobs, but Riku smiles anyway. Kisses Sion’s cheek. Noses at his jaw.
“Good alpha,” Riku says. “Best alpha.”
Sion strokes Riku’s hair. Closes his eyes. He just needs to keep this up, be a good alpha, be the best alpha for his omega. That’s all.
That’s all.
-
The shooting for the Return of Superman comes on a sunny day. It’s their only schedule, for once, so Sion doesn’t even mind the drive out to Yeoju. Riku snores on his shoulder the whole way there. He’s exhausted but lets Sion coddle him, feeding him breakfast, making sure he’s not drinking too much coffee.
The kids, when they found out, had been sad that they didn’t get to go play with the pups with them. Especially Sakuya, who is somehow convinced that he is a child whisperer (and when Riku had told him that it’s because he’s still a child himself, he had gone all sulky). But then Sion had told them all that the show is a secret ploy to instill hope in society’s secondary gender dynamics and raise the declining birth rate, and then they all had decided that they were perfectly fine with staying behind.
Kids, Sion very privately muses. They’re funny.
When they get there, the production team shows them around the campsite, their set for today. Shows them the toys and the gear and the food they have prepared. Sion has to think very hard about the fact that this isn’t, actually, a marriage simulator with his mate, but something that is going on TV. Even so, seeing Riku with the kids’ toys makes his heart leap in his chest. He tries not to dwell on it.
Once they start rolling, Sion gets sucked into the shoot.
It’s rare that it’s just him and Riku without the other members, so he has to put in a little more effort than usual to cover the aspects in which Riku is awkward. Cute and so very loveable, but awkward. Sion watches his mate greet the pups with barely-sealed fondness. It’s hard to not swoon.
Ohyun is adorable. The cutest kid Sion has ever met. Him and Byeol are both shy, but open right up once they get playing. Sion drags Ohyun around, tickles him, shows him bubbles - which, for some reason, are the way to every child’s heart. Byeol sinks into Riku’s side and they play with each other. It sends Sion’s heart soaring and soaring to see his mate so good with a pup, so tender towards her, and when they’re all under the tent together, Sion has to consciously stop himself from purring in satisfaction.
It’s hard not to. His alpha goes mate with pups, mate with pups, mate with pups, and Sion has to remind himself that technically, Riku and him are just boyfriends playing with random kids. But then his alpha starts off on a tangent of but someday, but someday, but someday, and then he has to turn his brain off entirely.
Stupid, stupid alpha brain.
Sion’s alpha wants to curl up with his mate and their two pups, almost to the point where it’s driving him crazy, so the bike ride is a welcome distraction. Byeol is sandwiched between them, and Riku is just as attentive to her as he is to the pups in Wish, if not moreso. He strokes her hair, makes her smile. They go back to the campground and eat and Sion can’t help but think about just how well he’s providing for his mate and their pups.
Not our pups! He screams to his brain. They’re not our pups!
But then Byeol feeds Riku a slice of pork belly and Riku says it’s good, hyung, and Sion feels smug about providing anyway.
(Riku would probably skin him if he knew that this is where Sion’s head is at during this shoot, but what his boyfriend doesn’t know won’t kill him.)
Watching Riku feed and take care of the pups stirs something foreign in his belly, something not entirely familiar but still scary. It doesn’t help that Riku is an omega, with caretaking so deeping ingrained in his biology. He cradles the kids, keeps them in his arms. The pups cling onto him gladly, from the sheer proximity of being in a nurturing omega. Ohyun clings onto Riku’s neck, right where his scent is covered up, and Sion can’t help but yearn.
(On the boat, especially, as Riku cuddles up to the pups and strokes their hair and scents them to calm them down - Sion’s alpha whines with mate, mate, mate.)
Luckily Sion gets distracted by trying to help Ohyun overcome his fear of boats, and his instincts take a backseat to being a responsible caretaker for these kids. He has to goad Ohyun into joining him on the deck the exact same way he has to goad Sakuya into eating enough vegetables, but as such, that’s just how kids are. Though Sion is definitely using this information against his maknae at some point.
The shoot is oddly peaceful. Outrageously tender. Even without his alpha instincts, Sion can’t help but feel the responsibility and care for these kids. It’s not often where he gets to relax while shooting, but the kids are easy to get along with. When they have to say bye and they cling onto him, he damn near cries. It doesn’t help that Byeol looks like Riku, something that tugs at his heartstrings. The pups get passed back and forth between them, with hugs and cuddles. The two of them cling onto Riku more, of course, which Sion isn’t even mad about. It only makes him feel even happier.
“I don’t want to say bye!” Ohyun whines into Riku’s neck. “Stay with me!”
They both laugh. Once the cameras stop rolling, his mom has to come and dislodge him from Riku.
(“Sorry, he seems to like your scent a lot,” she says.
“It’s okay, I don’t mind,” Riku smiles. “It’s cute.”)
It was a short shoot day and they wrap up before the sun starts to set. It’s a rare treat, only having to work for a few hours right before comeback season, so Sion takes advantage. He clings onto Riku once they get in the car. Peels his scent blocker off and scents him thoroughly, much to the displeasure of their manager in the front seat.
“What’s with you today?” Riku whines, but lets Sion do it anyway. Lets Sion rub their wrists together and nose at his neck and keep holding him close.
“Nothing,” Sion hums. Tries not to think about the image of Riku with pups, the idea of Riku having their pups, or the two of them having pups one day. He fails spectacularly. “You were just so good today.”
It’s not the truth, not entirely, and Riku can probably tell from the way Sion buries his face in Riku’s neck and refuses to come out. But he lets it go, running a hand up and down Sion’s back.
“Silly alpha,” he mutters.
Sion hums his agreement. Silly alpha indeed.
-
The next few weeks have him in an extremely weird state of mind.
Nothing is different, really. The six of them are all the same as ever, all still overworked and stressed to the point of exhaustion. Most of Sion’s energy goes towards making sure all of his members are mentally and physically sound, making sure that they’ll be able to handle the upcoming weeks of comeback season and the subsequent recording for their next album, which has been in its planning stages for weeks now.
No, everything is normal, almost to the point of absurdity. It’s Sion who’s being weird.
It goes like this:
Sion wakes up in the morning, untangles from Riku in their nest, and goes off to make a cup of coffee to drown himself in it. While the Keurig is brewing, most of the group rouses themselves from sleep, congregating in the kitchen, half-dressed for practice. The maknaes in particular all spend their mornings walking around like zombies. Yushi’s sleep schedule is too inconsistent to be bothered by early mornings.
But the weird part is that when Riku comes in, still doused in Sion’s scent, and starts pinching the pups’ cheeks and nagging at them for not going to sleep early enough, something in Sion’s brain goes absolutely haywire.
Pup him, his alpha whines. Give him pups. Make him a dame. Give him your pups, make him your mate, raise a family together-
And… well. Well.
So, yeah. As he was saying, things have been weird.
At first he thought it was a side effect of his odd cycle, but the issue is that it’s not going away. It mostly happens when Riku is cooing at the pups, feeding them and forcing water down their throats during water breaks. Absolutely nothing has changed about the way Riku is soft on their maknaes, all three of them, but now Sion sees him with them and can’t stop thinking about the idea of Riku with their pups, ones they made, a product of their mating. It’s so, so fucking bizarre and out of hand and Sion feels like an absolute lunatic with the way these thoughts have been completely consuming him.
“Did you and Riku hyung fight?” Ryo asks one day. They’re a few hours in on their new dance and they’re all strewn across the practice room, bodies exhausted. “You’re looking at him like you wanna kill him.”
Sion blinks. Yeah, he’s been staring after Riku, but not anymore than he usually does. And it’s not because he wants to kill him, it’s more like… he wants to eat him. Something like that.
Not that he can say that to Ryo, of all people, but still.
“Nothing happened, Ryo-chan,” Sion says, ruffling his hair. “Just kind of out of it today, that’s all.”
It’s close enough to the truth, because Sion is out of it. He’s out of it all the time, haunted by his own thoughts. Riku, who has a third sense for when people are talking shit, turns and stares right at them. Raises his eyebrows.
Sion, of course, blows him a kiss. Riku rolls his eyes but catches it out of midair anyway. Swallows it. Grins.
“Okay, ew,” Ryo says, grimacing. “Never mind, I can see that you’re happily in love as always.”
Sion laughs, as Ryo stalks away, jumping onto Sakuya’s back to bother him instead. Riku sends him a finger heart. Sion returns it.
Perfect omega, his alpha coos. Perfect, sweet omega.
Sion takes a sip of water, ears red. It’s not like he can disagree.
It gets to the point where Sion goes on Naver and searches: why am I obsessed with pupping my mate???? and Reddit tells him that he’s just horny and needs to get laid. Which isn’t true, thank you very much, because Sion has a perfectly fine omega who gets him laid on the regular. But there’s something definitely wrong with him and it’s too embarrassing to go to even Taeyong hyung with something like this, so Sion keeps to himself and tries not to freak the fuck out.
Well. Maybe there’s one person he talks to.
“Hyung,” Yushi says very slowly. “Is there a reason that you’re having a crisis in my bed, or…”
Okay, it’s not like he wants to talk about this. Especially not with Yushi. But he’s the only other adult in the group and generally has a good head on his shoulders when he isn’t being weird (which is often, but that’s not the point). The fact that Sion has decided to have his newest Riku-crisis in Yushi’s vicinity is nothing to be ashamed about!
“I think there might be something wrong with me,” Sion tells him. “Like, worse than usual.”
Yushi, bless his heart, doesn’t take that low hanging fruit of an opportunity to joke about Sion’s faults as a person, which is a list that’s growing by the week. He sits down on the edge of the bed and pats Sion’s knee.
“What is it this time?” he asks, which honestly does not inspire hope in Sion’s heart that Yushi will help him out with this. “Did you forget that you’re dating Riku again?”
Sion groans. “No, not that.” He hates that he even has to say it, but that whole incident is something his entire group will be holding over his head until he dies, probably. “But it does have to do with Riku.”
Yushi hums. “Is it the reason you’ve been weird since you filmed the Return of Superman?”
Sion stares at him. Yushi is impassive as always. How he always knows is just another mystery of the world.
“It’s not that I’ve been weird-”
“You have been, though,” Yushi cuts him off. “You’ve been really weird.”
“-IT’S NOT THAT I’VE BEEN WEIRD,” Sion repeats himself, “it’s just that I think that the show… um. Unlocked something in me?” He struggles for words. “Like, something in my biology.”
Yushi gives him a blank look.
“The Return of Superman did what to you?”
Sion sighs. He closes his eyes, runs a hand down his face. Not only is Yushi a beta, but he’s not someone who gets impassioned about, like, the idea of romance. He would much rather romance a bowl of ramen. Or a new girl group choreography. Or his phone.
Not that Sion’s new feelings are solely romantic and not horny, because they are. Horny, that is. But whatever.
“So maybe I have this thing,” Sion says. “Where every time I see Riku, I want to give him pups.”
He regrets saying it as soon as it’s out of his mouth. Because saying hey, I really want to breed my bandmate to another bandmate is weird enough as it is, their extremely close relationship notwithstanding. Yushi stares at him.
“Hyung,” he says. “Are you-”
“Actually, let’s not have this conversation,” Sion decides. He sits up, stands up. “Thanks for letting me use your bed, Yushi, I really-”
“Sit. Down.” Yushi pulls on him. Sion sinks to the sheets, obedient because Yushi holds grudges and Sion has long promised himself that he’d never have to face the wrath of Yushi’s ire. “Hyung. Tell me.” He frowns. “How horny can you possibly be?”
“I’m not horny!” Sion complains, way too fucking loud considering how thin the dorm walls are. But too bad, he’s insistent. “I’m not horny! It’s, like, a biological thing! It has nothing to do with horniness!”
“Pretty sure it’s cause you’re horny-”
“Stop telling me that I’m horny!” Sion groans. “I’m not!” Thinks about it. “Okay, maybe a little bit. But that’s not the problem!”
Yushi being a beta certainly doesn’t make it easy to put into words. The desire in Sion for his mate and their hypothetical pups is something so deeply instinctual, something driven by desire alone. By his biology, by his yearning to provide, by the need to see some sort of tangible proof that Riku is his.
Which, okay. Is kind of horny. But again, not the point!
He tries to think it through in a way that isn’t complete nonsense. Imagine there’s a guy in your brain who tells you all these dumb thoughts and sometimes you feel compelled to listen. Okay, no. So my alpha is horny and wants to breed my boyfriend and I can’t stop him. Alright, not that either.
SOMETIMES BEING AN ALPHA MEANS THAT YOU WANT TO BREED YOUR MATE!
Yeah, no. Definitely not.
“I just think…” Sion slowly says. “I just think that I’m more knotheaded than I thought I was.”
It’s the only reasonable explanation he can come up with. People his age are interested in finding mates. People his age try to start settling down. Surely this is something, like, evolutionary, and maybe no one ever bothered to tell Sion that it would start happening so early on in life. Maybe he really is just a dumb alpha, and this is just a part of it.
“Um, well, yeah,” Yushi says, like this is a no-brainer. “You kind of are.”
And, well. That seems like the extent of the help he’s going to be receiving today, so…
“Well, thanks for your inspiring words,” Sion huffs. He gets up, knowing that he has to get back to the nest before Riku comes looking for him, since Riku’s demands for his alpha isn’t a sight he really wants to subject any of the other members to. “I’ll, um, think about it. You know. Being less dumb.”
Yushi nods sagely. “Think less with your knot-”
“-and more with my brain, yes, you’ve told me,” Sion sighs. It’s really unfortunate that SM has been marketing him as the ideal Alpha Leader™ because moments like these certainly don’t make him feel that way. “Thanks, Yushi. Please don’t tell Riku.”
Yushi snorts. “Like I’m gonna give you two any more things to fuck about.”
Sion sends him a very disappointed Leader Look. Yushi is unaffected, of course. Grins right back. Stubborn boy.
Sion rues the fact that his best friend is a beta and therefore immune to biological urges, meanwhile his own alpha salivates at the mere image of Riku’s bare nape.
Jesus christ, Oh Sion, he tells himself. Get a fucking grip.
-
So it turns out that Sion does not, in fact, get a grip.
It’s hard to blame any of this on his cycle, not when his alpha’s viscous and needy and constantly running a commentary of mate, breed, mate, breed. They’re knee-deep in promotions and he’s fucking exhausted, between keeping both himself and the kids in line.
His job would be infinitely easier if he didn’t have to blackmail himself into not fantasizing about his groupmate’s neck every time Riku sits in front of him for an interview. If-fucking-only.
It’s like being in pre-rut all the time, without the actual excuse of a rut to explain his behavior. He even goes to one of the SM hormone doctors about it, just because he’s certain he’s going insane, but her explanation is that it’s his stress. Which is great, because luckily for him, there’s nothing more fucking stressful than being the leader of a rookie K-Pop group.
Just his luck.
Riku has been more doting, despite his own health issues. Leans into Sion’s side in the MuBank waiting rooms whenever the camera isn’t rolling. Purrs into his neck, just to keep him sated, and Sion hates that Riku even has to baby him like this when they’re all individually struggling enough. Not only is he his leader and his hyung, he’s his alpha. He’s the provider. But his omega is the one who has to soothe him instead, keeping him scented and calm and level-headed.
So much for being an alpha who provides. He’s doing a shit job at that, too.
Today is Daeyoung and Riku’s turn to go around and do challenge collabs with other groups. Sion is assigned to be the cameraman because his stupid fucking alpha won’t let Riku out of his sight, and the pups have had enough of him stinking up the waiting room with his sour scent. His pheromones have been strong enough to bleed through the blockers, recently, which is just another catastrophe on top of everything else.
And as it has been established, subtlety isn’t Sion’s strong suit. So he’s not doing a great job at keeping a handle on his displeasure whenever Riku goes around to the other waiting rooms, collecting albums and shaking hands. Possessiveness is a horrible look on him.
(He hopes to god that neither of the pups turn into the kind of alpha that he is. The obsessive, insane kind.)
They’re recording a video with an older group, two alphas. They’re both tall and buff and handsome and Sion is getting a little peeved - just a little bit! - that their eyes are lingering so long on his Riku. They’re too old for him! Too old and too tall! Riku needs an alpha who is just the right size and age for him!
“Hyung,” Daeyoung stage-whispers. “Your scent is kind of…”
Sion groans. Wants to dig himself into a fucking hole.
“Thanks, Daeyoung-ah,” he says. “Sorry.”
He records the damn thing with gritted teeth. The dance challenge is stupid. Riku, of course, looks perfect while doing it. As always. (And Daeyoung is fine too.) It takes longer than usual because one of the dumb alphas has a hard time following the moves (see? What a bad alpha!) and asks Riku to teach him.
Of course, sunbae, Riku says. Just look at what I do.
And he looks, all right. He looks Riku up and down. Gaze intense. Calculating. The look of an alpha who has clocked an omega, who is interested, who knows what he wants. Never mind that they’re rookies, and Riku is young, and they’re in the middle of working.
Sion’s alpha roars. Get away, get away, get away, get away-
Riku freezes in his movements. Looks at Sion, and then looks back at their sunbaes. “Oh, actually, I just realized hyung and I need to do this quick thing for our behind the scenes video, my bad,” Riku says with a smile. “Daeyoung, can you get Ryo instead, hmm?”
Sion blinks. Because what? And Daeyoung is saying uh sure, hyung, yeah-
And Riku’s pulling Sion into a very familiar empty closet and crowding him up against the door and ripping his scent patch off.
“You,” Riku groans. “Are such a bad, awful, terrible fucking alpha-”
“Sorry,” Sion mumbles, unsure if he’s really sorry at all as his senses fill with orange blossom, sweet as molasses. His head is spinning, torn between his previous jealousy and the fact that Riku is now offering himself up for taking. He leans down to nip at Riku’s neck, light enough to not leave marks. “Sorry, baby.”
“Shut up,” Riku hisses. “You’re not sorry.”
And to be honest, he’s right. So Sion shuts up.
They can’t mess up their makeup, so Riku just unbuttons his stupid jorts that make his legs look fucking delicious, and shoves his briefs off. Sion doesn’t know why Riku’s being so pliant and easy for it, not after the stunt he just pulled, but he’s certainly not complaining.
“In me,” he says. “Hyung, get in me-”
“Yeah, yeah, okay,” Sion says a little dumbly. Gets his cock out, rubs Riku’s clit, which is begging for attention. He’s dripping fucking wet, for some reason. Even though they haven’t so much as kissed. Sion wonders why, for a second, but then his alpha goes do you think they smelled it on him? Those alphas? All his sweet slick? And then even worse: Is he wet because of them?
So then he’s very quickly disregarding that thought to plunge his cock right into his mate’s pussy.
“Mine,” he groans, as he pounds right in. Riku takes him so easy. He mouths along Riku’s neck, pushes him up against the closet wall, holding him firm. “You’re mine.”
“Yours,” Riku gasps. Whines when Sion scrapes over his scent gland. “So deep in me, fuck, hyung-”
There’s the deeply ashamed part of Sion that notes that this is the only time they’ve fucked since promotions started, since his alpha has taken over his brain, since he’s been so caught up in his own shit. His alpha is crying breed, breed, breed, stuff him full of pups, make him take it, make him a dame with your knot-
Which isn’t unusual, except for the fact that it’s all he can think. He’s lightheaded with the image of Riku carrying his pups, Riku swollen with his pups, Riku taking care of the pups Sion gave him, Riku full and full and full.
It gets him to the edge embarrassingly quickly. Sion thumbs at Riku’s clit, pants in his mouth.
“Baby, where-” he gasps. “Baby, where do you want me-”
“Inside, alpha,” Riku moans. “Please, please, inside me-”
It’s the messiest thing they’ve ever done, the least coordinated, but Sion is spilling inside him with a groan, filling him right up. Riku keens as Sion grunts a final thrust, tugging on his clit, and then he’s coming too.
They take a moment to heave, catching their breaths. Sion tries not to think about how this is the second time they’ve defiled this very closet.
“God,” Riku pants. “Should've known this was gonna happen, should’ve brought a plug.”
Sion’s brain, hazy with orgasm, short circuits.
“A plug?” He asks. “You want me to plug you-”
“Just so I’m not dripping, you idiot knothead! We’re performing in an hour!” Riku hisses. “God, I swear you’re the neediest alpha ever.” But he’s nuzzling into Sion’s scent gland, mouthing at it, so Sion’s kind of getting mixed messages.
“Sorry, jagi-yah,” Sion whispers. Finally coming to his fucking senses. He’s not even in rut, what the fuck is wrong with him?
“‘S fine,” Riku sighs. “Let’s just not do it again. Keep your stupid alpha under control.”
-
Needless to say, they do it again.
-
Promotions go by and Sion’s feeling like he gets a better grip on himself. His possessiveness tapers off, as their schedule dies down a little more, something he’s infinitely grateful for. It might’ve all just been a weird anomaly, he reasons. A glitch in the matrix.
But then the first episode of him and Riku on the Return of Superman comes out and he realizes that he was very, very sorely mistaken.
The pups are gathered around the living room TV, on KBS’s Youtube channel. He has no idea why they’re all so excited to watch it, but he’s not complaining. Sion plops down on the couch, sandwiched between Sakuya and Ryo. Riku sits between his legs.
“Should I hit play?” Daeyoung asks.
“Go ahead!”
It’s very typical content, all things considering. It’s edited in a way that makes the two of them seem like normal groupmates, platonic alpha and omega. Shots of their recent promotion, some MV clips. But then when the kids come out and Sion gets to see Riku approach them with full 4K quality - the way Riku smiles down at the pups - he knows that he is entirely and completely fucked.
His obsession with breeding is something he thought was just indicative of his age, of his biology, but now he’s realizing that it’s indicative of Riku. Because he watches Riku caress Byeol’s hair and play with her, keeping her hydrated and fed and cool with the fan, and Sion is thinking that’s my mate, that’s my mate, isn’t he perfect? So good with pups. Gonna give him pups.
“Hyung,” Sakuya complains. “Your scent’s getting gross.”
Sion goes red. He’s not horny but the yearning is palpable in his scent, the possessiveness. Ryo gives him the stink eye.
“You guys are already dating, you know,” Ryo blanches. “You don’t have to posture in front of us.”
Unfortunately, Sion isn’t posturing. His alpha is just ridiculously, ridiculously happy.
Riku, thankfully, couldn’t care less. He smushes his cheek into Sion’s knee and plays with the hem of his sweatpants. Hand around his ankle, just holding it there. He laughs as the pups complain about their gross hyungs. He coos at the video, as Ohyun and Byeol smile and laugh and whine.
“Ah, they’re so cute,” he says. “Makes me wanna have pups.”
It’s a normal comment an omega would make. There’s nothing weird about it. But Sion freezes because it’s only giving his alpha permission to run with his thoughts, think about Riku as his mate, Riku as a dame, Riku carrying his pups. And his alpha is thinking mate wants them, mate wants them, give them to him, he wants them.
Sion clenches his jaw. Digs his hands into his thighs.
Be normal! He begs his alpha. Just be normal!
Luckily the video is short and they finish it before he can cause any more of a scene than he already has. The pups are talking about how cute the kids are, how jealous they are that they didn’t get to join, and Sion very slowly relaxes. He strokes Riku’s hair with his fingers, trailing through the strands.
Okay, he thinks. Everything is fine.
But then Daeyoung is scrolling to the Youtube comments and things are decidedly not fine.
“Let’s look at what they’re saying!” Daeyoung says. “Ooh, look-”
He falters. The top comment: Riku is such a good omega T_T want him to be my mate!
“Oh,” Daeyoung says. “Um.”
Sion blinks. That’s… huh. So. So.
So there are viewers who just watched Riku spend twenty minutes with his alpha, and they think that that means Riku should be theirs. Riku, who is perfect with pups. Riku, who is nurturing and silly. Riku, who frets over anyone younger than him.
“Never mind,” Daeyoung is saying, trying to exit out of the comment section. “We shouldn’t-”
Sion very unceremoniously snatches the remote out of Daeyoung’s hand and keeps scrolling.
“Hyung, actually-” Ryo is saying. “You don’t have to-”
The comments are all the fucking same! Full of ah, Riku-ah is such a good omega, do you think he’s looking for an alpha lol and how could anyone resist an omega like that? and yah I need to mate him! Right now! There’s even one that says if I was Sion I’d have him locked down, Riku is the perfect mate.
Sion is seething. Absolutely seething.
“Great, he’s jealous of the fans now,” Ryo is murmuring.
“Hyung,” Riku is giggling. “Hyung, they’re just comments.”
Sion actually couldn’t care less. Absolutely not. Not when Riku is his, his omega. He’s already taken, and he’s gonna be pupped and mated, and they’re all gonna look fucking stupid when he-
“Alright, well, I’m gonna go,” Daeyoung says. “Smells like a coffee shop in here.”
The maknaes scramble off. They’re always quick to make themselves scarce when Sion is in a mood.
It really doesn’t help that Riku is laughing. He must think this is all hilarious.
“Hyung,” he coos. He climbs up on the couch to plant himself in Sion’s side. “Hyung, why are you getting jealous?”
Sion makes a pained face. “I’m not,” he lies.
Riku smiles. “You are.”
“Am not.”
“You definitely are!”
“‘M just a little upset,” he argues, which is also a lie. Because he’s not a little upset, he’s the most upset he’s ever been. Puts an arm around Riku, squeezes him in close. “‘Cause you’re mine.”
Riku grins. He noses at his scent gland. “I am. So there’s no reason to get mad about a few comments.”
He’s right. Of course he is. But Sion is thinking about other alphas getting to see his mate with pups, getting to know what Riku is like when he’s being a dame, and his alpha is still seething anyways.
“‘S not a few comments,” he grumbles. “It’s all of them.”
Riku chuckles in a sigh. He snips at Sion’s neck. “Such a knothead,” Riku says. “Can’t believe I put up with you.”
Sion can’t believe it either. Because a few months ago, this wouldn’t have bothered him. He probably would’ve been proud that his omega is so well sought after. But now his head is full of mine, mine, mine, mine-
God, he feels like a fucking idiot. Like the biggest, stupidest alpha on earth. What happened to being well behaved for Riku? What happened to being the best alpha for his omega?
Sion’s alpha is grumbling. He scents Riku thoroughly. Says nothing in response.
Something needs to get fixed, now.
-
The catalyst is, of course, Riku himself.
Riku’s in pre-heat and Sion has him laying on top of him, stroking down his back, soothing. They tried to work with the group this morning, they really did, but his mate’s been cramping bad enough that he had to sit out of dance practice, so Sion did the responsible thing and left it all up to Yushi and took Riku home.
Yushi was thrilled, obviously, and so was Daeyoung. Whenever one of them’s in a bad part of the cycle, their scents stink up the practice room, and even the choreographer was talking about ending things early. Daeyoung is still learning control over his sensitivity to scents and Yushi’s nose is absurdly keen, so they all-too-eagerly pushed their hyungs out the door and into one of the manager’s vans with a see you later! We’ll bring home food! and that was that.
So now Riku is naked, on top of him. A little needy, mostly just tired. Perspiration clinging to his body, soaking Sion’s clothes, though Sion has no complaints about taking care of his mate when he needs it the most.
However…
“Hyung?” Riku asks, suddenly, cutting through easy, companionable silence. “Do you want to ever have pups?”
The question comes as a surprise. Riku is usually dead-silent in the hours leading up to his heat, otherwise just sleepy and a little moody. It doesn’t help that when Riku says it, he looks up at Sion with wide, kitten-ish eyes.
Sion sucks in a breath.
He can’t tell, really, if Riku has caught onto him or not. Riku is deadly perceptive about some things, oblivious about others. Can read scents well but isn’t as good about baseline emotional stuff, whereas Sion is the exact opposite. Though Sion has a feeling that Riku has more likely than anything caught onto the recent uptick of want, desire, omega, breed, in his scent. If Yushi’s constant glares in his direction are anything to go by, he’s being plenty obvious.
“Um, yeah,” Sion says. His voice comes out oddly strained. “Of course I want pups, someday. Why?”
Riku shrugs. His scent is happy, unbothered, which is extremely odd considering that he’s usually tired, crampy, alpha, help, this time of his cycle.
“No reason,” he says. “Just making sure we’re on the same page.”
And Sion’s brain screeches to a halt.
The same… the same- the same page?
His brain goes completely, completely off the rails. Because okay, yes, they’re as good as mated, but they’re both young and naive and haven’t got into explicit details or agreements about how and when and if. How they could mate, when, if it was possible. It floats around Sion’s mind every now and again, of course, but he usually pretends it doesn’t because they’re so early in their career and sometimes the future is just one big question mark.
“Do you…?” Sion asks, very very slowly. Because he doesn’t want to make assumptions, because he wants to be careful, because this is Riku. “Do you want pups, too?”
This isn’t the time to be having this conversation, not really. Riku isn’t a hundred percent lucid, technically, not when they’re only hours away from his heat kicking in and taking them both under for a few days. But if they’re going to have this conversation, it may as well be right now, because when else could they? When this is one of their few opportunities to be honest, let biology take over their instincts?
Riku grins. “Obviously,” he says. And does not elaborate any further.
And. Well. Riku nuzzles into his neck. Nips at his scent gland. Sion lays there, completely frozen, staring down at his boyfriend making a home for himself in Sion’s scent after announcing that he wants pups… with Sion? With Sion?
“Baby,” Sion says distantly. “Um, hey, hold on-”
“D’you know how insane you’ve made me these past few weeks,” Riku cuts him off. His voice is sweet and low but there’s a very subtle growling quality to it. “I can smell you, hyung, we all can. How you want me, how you wanna fill me up, how you wanna breed me-”
“Riku,” Sion says faintly. “Riku, sweetheart-”
Riku straddles him. Absolutely no preamble, just sits on his lap properly and grinds his hips down, arms wrapped around Sion’s neck.
“Someday,” Riku says. Puts a hand on his stomach. “Someday you’re gonna give me your pups, and they’re gonna go right here.” He pulls Sion’s wrist, rests his hand over his naval. “You’re gonna fill me up, and you’re gonna breed me, and we’re gonna have our own pups, hyungie, and-”
“Riku,” Sion says, desperate, a low growl coming from his throat. His head tips back because his brain is dizzy with wanting to breed him, knowing that Riku wants it too, knowing that one day they’ll get to- “Riku, honey,” Sion pants. “Have mercy on me. It’s not even time yet.”
“No,” Riku grins. His teeth are sharp, familiarly predatory. “Don’t care when it’s time. Need my alpha to claim me.”
They’ve never done this, fucking before the heat hits. Usually Sion prefers to save energy, since Riku will wring him out in the days to come anyways. But Riku’s scent blares through the room, cloyingly sweet, singing need you, alpha, inside me, inside me-
Sion feels the last remaining shreds of his sanity very slowly begin to snap.
“You-” Sion says, distracted by Riku grinding down against him. He’s wet, so wet, soaking onto Sion’s sweats, and Sion is so hard he feels like he’s going to fucking die. “You want me? You want my pups?”
“Who else?” Riku asks. His fingers curl into Sion’s shirt. His lips ghost along Sion’s jaw. “You think I’m gonna let another omega have your pups? You think I’d let another alpha inside me-”
“No,” Sion growls, hands flying up to Riku’s hips and pressing a bruising grip into his skin. “No, absolutely not, fuck, you’re mine-”
It’s early - too early - but Riku’s scent is screaming how bad he wants it, and Sion has never done anything except exactly what his omega wants him to do. Riku moans as Sion grips onto him, pulls him down into a thrust, Riku’s slick permeating the air and making it impossible to even think.
“Please, alpha,” Riku whispers. He leans back, arches his back, tips his head back - throat on display, pulse point pounding and his scent gland just… right there. Easy to claim. Sion grips onto him harder.
“Riku,” Sion warns him, or tries to warn. “Riku, if we start now, we’re not gonna stop-”
“Hyung,” Riku whines. “Hyungie, please.”
And, well. At least Sion tried.
He pulls off his shirt, preemptively minimizing mess, and then he pulls Riku up his lap by his hips, sitting him right over his cock. Grinds up onto him, as dirty as he can. Riku mewls, hands clinging onto Sion’s shoulders.
“Honey,” Sion pants. Doesn’t know if he should be begging or demanding. “Honey, I wanna sit you on my face-”
“But hyung,” Riku whines. “Want you to fill me up-”
“After, sweetheart,” Sion growls. “After I make you squirt on my tongue, I’m gonna fill you. Come here, take a seat on alpha’s face.”
Before Riku can protest any more, Sion picks him up by the waist and sits him down over top of him. Riku is hovering, complaining, just wanting to be full, but Sion forces him down. Gets his cunt right on his tongue, finds his clit, sucks. Riku buckles his hips and starts moaning ah, hyung, please, please-
Sion growls. Moans. Right into his pussy, eating him up, unable to believe just how good his omega tastes. Orange blossoms and sweet, sweet fragrance, in all of Sion’s senses. He gets Riku’s riding on his tongue, using Sion’s mouth to get off, squealing hyung! Hyungie! Gonna make me come! I’m gonna-
Sion licks him open, digs right into his cunt, one hand gripping his thigh and the other petting at his asshole with barely-there force. It’s hardly anything, but then Riku is squirming, is crying out, is trembling so, so hard-
“Alpha,” he moans. “Alpha, ‘m coming.”
Sion lifts him, sinks two fingers in him - all the way down to his sweet spot - and Riku is shaking as he squirts on his face.
Sion can tell the heat has set in early, because it’s only one orgasm and Riku is barely coherent. He’s trembling like a leaf in Sion’s hands as he licks him clean, drinks up his sweet slick. Sion doesn’t even give him the satisfaction of coming down from his high, just flips him around onto his stomach and then manhandles him back onto his lap chest-to-back and makes his perfect little omega ride his fingers.
“Alpha,” Riku cries. “Alpha, alpha, alpha-”
“How does it feel, sweet thing?” Sion coos. Riku’s clenching so sweetly around him, so full from only two fingers. Hips shaking from overstimulation, and Sion sees no reason why not to just prolong it. Make it last forever. Make his omega feel so good that he loses his mind completely.
“Good-!” Riku gasps. His hands are scrambling, clinging onto Sion’s wrists, holding onto him as Sion pounds him with his fingers. “So good, hyungie, it feels so good, think you’re gonna break me-”
“Haven’t even got my cock in you, yet, baby,” Sion grits his teeth. Pummels sensitive muscle into nothing but pleasure. “Haven’t even got my cock in you and you’re already crying.”
“Not-not my fault,” Riku slurs. “Not my fault my alpha is big everywhere, always fills me so good-”
Sion sucks in his breath. Wrenches his thighs open even wider, smacks down on his clit. “Fuck, baby-” he pants. “Fuck, give me another.”
Riku has his head tipped back, lolled on Sion’s shoulder. Sion nips at his scent gland - not enough to leave marks, not enough to be anything but a promise and to layer his own scent over top of Riku’s - and says at his ear while Riku whines: “Another one, angel, come for alpha again.”
“But hyungie-” Riku keens. “Hyungie, I can’t.”
“You can,” Sion growls. Puts one hand at the base of Riku’s neck, squeezes just the tiniest bit. Jams a third finger inside him, curls up against his sweet spot. “You can, come on.”
Riku pants. Whines. Arches into the touch on his throat, the claiming nature of it. “Hyung-” he moans. “Hyungie-”
“Riku,” Sion groans. “My Riku, my omega, my little omega, what do we do when hyung tells you to come? We listen to hyung, don’t we? When alpha tells you to do something, what do we do, sweetheart?”
“Come,” Riku babbles, throat gurgling. “‘M gonna come-”
“That’s right,” Sion growls, runs his teeth down Riku’s scent gland, hard enough to leave a red line. Forces his fingers down over his sweet spot and presses as hard as he can. “That’s right, be a good omega and come.”
Riku listens. Of course. He always does. His back arches as his cunt squirts, drooling onto Sion’s fingers. Goes limp as his thighs tremble.
Sion lets go of his neck. Slows down his thrusts but keeps his fingers curled up against his sweet spot, getting Riku to cry out. He’s moaning, squealing hyung, can’t take any more, need your knot, please, hyung, please-
Sion is a simple man. His omega begs for him, he listens. He lifts Riku off his lap, tugs down his sweats and briefs, and plunges right inside.
“Alpha-!” Riku gasps as Sion sinks down, down, down, deeper into him. Punishing, hard enough to bruise. Sinks onto hands and knees as Sion manhandles him into position, listens to his alpha groan at his wet heat sucking him in so well. “Alpha, it’s so good-”
“God, all you need is my cock,” Sion growls. Pulls out, thrusts back in. Riku takes it so easy, tight and hot and wet, wet, wet. “All you need is your alpha inside you, breeding you, filling you up-”
“Please,” Riku whimpers. His fingers curl into the sheets of their nest, back arching in presentation. “Want alpha’s pups. Want alpha’s pups so, so bad.”
His scent surrounds them, to the point where Sion is suffocating on it. So sweet and obedient and please, please, please breed me. His nape is bare, right for the taking, and Sion has to fight against the overwhelming urge in his body to just bite down. Just claim him. Make him yours, make him yours forever-
“Tell me,” Sion groans instead. “Tell alpha how bad you want it.”
Riku cries. “Don’t want it, I need it.”
And there really isn’t a single thing Sion can do, after that, to do anything but listen.
He snaps his hips, punishing, bruising. Slides his omega up and down his cock, pummels him where he knows it’ll feel best. Where he gets Riku screaming breed me, alpha, please, want your pups, need to be full with it-
“You’re gonna swell with me, baby,” Sion pants. “You’re gonna swell with me and you’re gonna have to perform with your tummy all full and everyone’s gonna wonder who sweet little Riku’s alpha is-“
“I’ll tell them,” Riku says. “I’ll tell them that I’m Sionie hyung’s.”
“Of course you will,” Sion grits out. “You will, because you’re mine, because my omega is so, so good for me, is gonna take it, is gonna take me until he’s pregnant-“
Sion wants to sink his teeth into his neck, wants to bite, wants to own him. Because his omega is so sweet, so honest, goes so pliant around his cock and clenches down on him like he’ll cry if Sion doesn’t breed him full tonight.
It sets Sion alight. The past few weeks have driven him insane, have made him feel so fucking crazy, but here’s Riku begging for it. Asking for him, wanting the same thing, pleading for Sion to fill him, fill him with pups, fill him until he’s swollen and can’t take anymore. Sion’s alphas roars, impossible to quiet.
His mate wants to get bred- Sion is going to breed him.
“Alpha,” Riku begs. “Please, please, please, please-“
“I am, sweetheart, I am,” Sion growls. “‘M breeding you, ‘m fucking you full, ‘m keeping you warm with my fucking cum, honey, ‘m gonna make you take it ‘til we’re sure you’re knocked up-”
“Oh,” Riku gasps. “Oh, hyung-” and then he’s squirting around Sion’s cock, trembling, and gasping out.
He came just from the feeling of being full, not even from his clit being played with. It’s the kind of thing Riku can only do when he’s in heat. The feeling of him clenching around Sion’s cock, sweet and pathetically desperate, makes him feel like he’s burning.
Sion pounds him. Fucks him through overstimulation, fucks him until he’s sobbing, fucks him until he’s so weak that the only thing holding up his hips is Sion’s hands, firm grip on them, right at the perfect position to bully Riku’s sweet spot and get him crying and crying and crying.
“Who does this cunt belong to?” Sion growls. “Who gets to fill you up?”
“Hyung does,” Riku sobs. “Only hyung gets to be inside me.”
The obedient answer makes Sion’s blood fucking sing. Singing at how easy Riku is to satisfy, how simple he is when Sion’s cock is in him, how pliant he is once he’s full and getting fucked until he’s bred.
“Which hyung?“ Sion asks. “Which hyung owns you?”
“My only hyung,” Riku babbles. “My only hyung, my alpha, my mate-“
“Fuck, sweetheart,” Sion hisses. “That’s right. You’re mine, this cunt is mine, gonna fill it right up.”
Riku’s heat is suffocating, has sweat dripping down Sion’s back and hairline, has him gritting his teeth and fucking his mate until he’s sore. But his brain is chanting breed, breed, breed, and it’s like nothing else matters at all - all that matters is filling his mate up and making sure it takes, making sure his pups get carried, making sure the two of them are tied together forever.
His knot starts swelling up. Riku sobs once he feels it, clawing at bed sheets and crying please, alpha, alpha, please, in me, breed me-
“You want alpha inside?” Sion asks. He scrambles to get Riku’s clit under his fingers, wants him to come again and again and again. “You want my pups, honey, you want to be full-”
“Yeah,” Riku gasps. “Yeah, want it.”
And that’s really all it takes. Riku’s cunt clenches around him and Sion’s coming, his knot popping and feeling like he’s experiencing a high he can never come down from. He thrusts into Riku until he’s filling him up, until Riku is crying, genuinely crying, and his cunt pulses one last time.
His nape is there, for the taking. Sion doesn’t bite. He soothes his hands over Riku’s bruised hips and thinks not now, someday, one day we can, not soon but eventually, one day my mark will be there-
“Hyung,” Riku moans, voice broken. “Love you so much.”
Sion coos. Runs his hands down Riku’s sides, massaging, even as Riku gasps with the aftershocks of being filled, Sion’s knot nestled right into his sweet spot.
“I love you too, Riku-ah,” he smiles. “Hyung loves you so much.”
It’s rare that things ever get that intense right off the bat, because Sion likes to work up to it. Like to make Riku deserve it, likes to get a few just from playing with his clit before his fingers ever even breach his cunt. But now that they’ve done it like this, he doesn’t know how he could ever go back. Riku is panting into the sheets, whining just from being full, and this is the easiest he’s ever been with Sion’s knot in him. Normally he’s squirming, restless. Needy.
Now, all he does is ease his back against Sion’s chest, nodding off, and whimper: “hope it takes, hyungie. Hope we get our pups.”
And, yeah. Sion doesn’t think he’s ever been so gone for something in his life.
Riku snores against his shoulder. Sion runs a hand through his hair as his knot slowly deflates. Riku will cry when it leaks out of him, later, but that’s a problem for future Sion.
Our pups, Riku had said.
Even if it can’t happen any time soon, even if it never happens, Sion can’t lie. The sound of that is his favorite thing in the world.
-
They talk about it once the heat is over. Riku tells him yes, hyung, we’ll mate one day. No need to always be so jealous. Tells him that he wants Sion’s pups. That he never wants another alpha.
Sion calms down a lot after that.
He goes back to normal, mostly. Far less possessive. Still freezes when pups and Riku are brought up in the same sentence, but that’s mostly because Riku grins at him with a very specific look in his eyes whenever it happens.
Horny little fucker.
It really doesn’t help that Riku likes him possessive, for whatever reason. Even though he’s headstrong and independent and nags at Sion whenever he coddles him too closely, he has a weird thing for Sion posturing for him in front of other alphas. Which Sion rarely ever does, since something like that could ruin his career, but the MuBank closet gets used frequently because Riku likes making him jealous.
It gets him wet, panting, and Sion’s back is hurting from all the times he’s had to sit his mate down on his cock while they’re standing up in that cramped little room. Little mercies, though, because Sion’s not complaining about his omega begging for his knot.
It’s around a year later when A&R approaches them again. With the Return of Superman. Again.
“Yes!” Riku exclaims at the same time Sion groans, “no.”
The breeding kink has ruined his life. Riku obsesses over it, begs for it, which is fine except for the fact that it drives Sion’s alpha crazy. Makes him delirious with it, makes him obsessive, makes him want to fuck Riku full every time someone even just mentions pups.
The production noona blinks at them. “Um,” she says. “Is that a yes, or…”
Riku looks over at Sion. Makes his eyes go wide, pleading. That look on his face that gets Sion itching, gets him possessive, gets him mean.
“Fine,” Sion relents. “We’ll do it.”
Riku cheers. The A&R team smiles. Sion sighs, defeated.
Whipped, Yushi’s voice says in his head. Sion tells the voice to shut up.
