Work Text:
The thing is that Maeda Riku would be hard pressed to call his life conventional by any means.
He wakes up on an early morning back in Seoul. February is biting and Fukui wasn’t much better, and yet it somehow feels so different after living in Korea for the last couple of years. He can feel the difference in the air, his alpha breathing down his neck as he sleeps, Riku tucked snugly into his arms. He was in Japan for months and while being wrapped up with Sion in the nest isn’t unfamiliar, it’s just… it’s just been a while.
Being gone for those few months really had him disoriented after so long of being under SM’s watchful gaze, after so long of living a life that only took him from one schedule to the next without an end in sight. Resting was hard. Doing it alone was even harder. Coming back took a bit of adjusting, but he’s slowly coming back into things with the rest of the group, slowly finding his footing again… slowly getting used to all of the focus back on him… all the attentiveness and doting…
Most of it comes from Sion. His unwavering gaze leveled at Riku’s face, the gaze that makes him shy again. It’s not a bad thing, to be shy - not when his hyung thinks it’s so cute - but the full force of Sion’s adoration sometimes makes his knees feel weak. Sometimes it makes him want to hide.
He blinks, waking up more abruptly when he feels a mouth on his scent gland, slowly working at him. Lazy, unhurried. The threat of teeth against his skin. Riku hadn’t noticed him wake up. He moves just the slightest bit, arching away, ready to say something, when Sion lets out a sound like a low, gentle growl and there’s the barest flex of hips against his back, and-
“Morning, baby,” Sion murmurs. He’s still buried snug inside of Riku - yes, they slept like that like absolute deviants. It’s felt like forever since he’s been made to take a knot, forced to reconcile his heats with nothing but a dildo and his hands, and this just feels so good. It’s embarrassing how good it feels.
“Hyung,” Riku breathes, leaning into his alpha’s touch, all thoughts about Fukui leaving his mind as Sion pulses inside of him. Sion’s not bearing a knot right now, but he’s still plugging him up, hard and aching. It feels so familiar, feels so nice… Riku moans when Sion nips at him. “Hyungie, you’re so-”
“Can’t believe I survived without you for five months, you’re perfect,” Sion sighs, plastered to his back, breath making the hair on the back of Riku’s neck stand up. A hand slides down Riku’s inner thigh, hooking under his knee and lifting him… stretching him open…
Yeah, it took a little bit to adjust back to this, all the affection and adoration and physical nature of their relationship hitting him with full force. Sion had tried to approach him slowly, really, but Riku was just as desperate to be filled and owned and claimed. So when his rut hit a couple days ago, it was only natural for them to fall into bed together, as good as mated and easy for each other.
Riku feels dizzy from the sudden onslaught of want that overtakes him. He just fucking woke up, for christ’s sake. But hyung makes everything feel so good and it’s so easy to just take it. So easy to just go pliant and let him deeper inside, let him do whatever he wants...
“You want it, princess?” Sion asks, lifting Riku’s knee to his chest to make him take it properly. “You’ll let alpha knot you again?”
Riku can feel the threat of a growing knot against him. Can feel Sion inside, keeping him full. It’s insane how much he wants it, even outside of heat. He’s gone way too fucking long without it, making him needy and squirmy and pleading. Riku leans his head back, turning to nose at Sion’s cheek.
“Hyung…” he says. “Alpha.”
Sion huffs out a low, evil chuckle. Dark and dangerous and teasing.
“Stuffed your cunt full and you still want more,” he mutters, low at Riku’s ear. “Don’t worry, hyung will give you more.”
It’s not fair how fucking good it feels when Sion bullies his way inside him, thrusting out and then right back in. It’s not fair how Riku’s body just takes it like he was made for this, back arching and cunt clutching down on him. The two of them were nothing more than just words whispered over the phone for so long, but this is real. So frighteningly real. Sion groans in his ear as he fills him and Riku is helpless against his alpha’s pleasure.
“Hyung,” he moans, panting for it as Sion pulls in and out of him, making him take it. “Feels so good, alpha, love when you’re inside me-”
Saying it makes him feel dirty but Sion growls, spreading him wider and bullying right into his sweet spot. “You’re so fucking cute,” Sion nips at him. “Wanna fucking defile you, keep you full with my pups, baby.”
That gets Riku to whine. His hyung always says such nasty things when he’s in rut, always talks so dirty that Riku can’t help but clench down on him. And then Sion fucks him even rougher.
“Fuck! Hyung!” He cries when Sion pounds into him, stretching him so wide that he can feel his sore, aching pussy try to keep him inside. “It’s so-! Too much-!”
“You wanted this, princess,” Sion growls in his ear. “You spent all night begging for me to breed you and now-” He groans. “‘M gonna pump you full of me, fill you until it takes-”
“Holy shit,” Riku wails when Sion presses harder down onto him, one hand under his knee to keep him open and the other sneaking around his shoulders to loosely hold him by the throat. Just the threat of it - the presence of it - is enough. “Hyung, you’re so deep inside,” Riku cries. “You’re in my tummy, I can feel it-”
“Hold your leg open for me, baby,” Sion groans. “Wanna play with your pretty pussy.”
Fuck. Riku moans as he listens to his alpha, holding his leg open as Sion’s fingers find his clit and tug at it. There’s real tears threatening to escape his eyes because it feels so fucking good, getting Riku to drool into his pillow with a guttural moan.
“You’re so fucking good around me, wanna breed you,” Sion hisses in his ear. “My baby’s so fucking pretty, taking hyung so easily, loving it-”
“I love it,” Riku cries. His brain is scrambled after two full days like this, fucking like rabbits, taking Sion so deep inside that he can feel himself gaping. He hasn’t been so well used in months, not when Sion was fucking him so delicately before his hiatus, worried that Riku would break.
Getting owned and fucked properly full like this has him panting, ready to beg for his alpha’s knot. Ready to beg for anything.
“Good boy,” Sion huffs in his ear when Riku clenches down on him. “You’re so fucking good, gonna breed you, gonna give you my pups-”
“Alpha,” Riku begs. “Alpha, please.”
Sion’s growling, biting at his scent gland, not breaking skin but toeing the line. He rubs Riku’s clit so well, making him feel like he’s going to die. His body is so tense, ready to come apart, and his hyung toying with his sensitive cunt doesn’t make it any easier. Sion’s fingers are so cruel, knowing just how to get him the most keyed up.
“Wanna feel you come, honey,” Sion growls. “Wanna feel you take it, wanna keep you full-”
“Hyung,” Riku sobs. His cunt clenches down, sensitive and sore after being fucked full for so long. He reaches back to fist his hand in Sion’s hair, body tensing. “Hyungie, it’s so good-”
It is. He’s edging the line of the precipice and he’s so warm-tight-full that it feels like Sion’s going to fucking break him with his knot, keep him filled up forever. He wants it, in the haze of the rut. He wants to be filled for forever.
Sion rubs at him harder. “Princess,” he says. “Princess, come on my cock.”
Riku can’t help but squirm. He can take Sion’s cock but he came so much over the past few days that it’s made him more sensitive, more whiny. He can hardly take it when Sion’s hand slaps down on his clit, making his back arch.
“I can’t,” he whines. “Can’t do it, feels too good-!”
Sion growls in his ear. “You can,” he says. “You’re gonna come on hyung’s cock like a good boy, you’re gonna squirt for me-”
And that’s not fucking fair, obviously, because Riku always listens to his alpha. So he clenches down with a cry and comes.
It’s a vicious orgasm, considering how far they are into the rut. It makes him mewl and whine as his thighs quake, body not knowing what to do as the intrusion bullies an orgasm out of him so mind-numbing that Riku’s jaw goes slack. Meanwhile Sion is growling, his rut the only thing on his mind as he pounds into him and just takes and takes and takes.
Sion’s knot batters against his pussy, ready to bully its way inside. Riku drools as Sion holds him open, still rubbing his clit, determined to fuck him so hard into overstimulation that he comes again and again and again-
“Hyungie,” he whines, mind hazy. “Oh, hyung-”
“You’re so good,” Sion moans. “You’re so fucking good.”
He lets himself be used. Lets himself be a little sleeve for his hyung to fuck into. Sion is vicious like this, holding him open as his knot grows bigger and bigger and threatens to slip right in, threatens to make him take it, threatens to fuck him full-
”Just take it, baby,” Sion growls. “Just let hyung inside, lemme breed you-”
It doesn’t take much after that. Riku wails as Sion’s knot forces its way inside and the alpha comes. Fucking him so deep and so full that Riku loses his fucking mind, cunt throbbing as he’s forced to come again. It feels so good. Feels so full. It’s lovely. So fucking lovely.
“Alpha,” Riku moans. “Alpha, love it.”
He can feel Sion inside him. He can feel himself being made to take an intrusion that would be too large for anyone else. It feels like heaven, feels like being owned as Sion pants, scraping his teeth over Riku’s scent gland. A promise. A threat. An inevitability.
He wants it. He loves being owned like this. Loves belonging to his hyung, being his princess, made for him and no one else.
“I love you, honey, fuck,” Sion huffs. “Missed you so fucking much, can’t believe it’s been so long since hyung’s had you like this.”
Riku mewls as Sion turns his head and kisses him on the mouth; devouring him; owning him; breeding him full. Sion always kisses him afterwards, claiming him with his teeth and his tongue and Riku fucking loves it. Loves being kissed, loves being eaten whole like he’s the most delicious thing Sion’s ever had.
“Hyung,” Riku mutters. Trying to say I love you but being unable to find the words.
“You’re so pretty,” Sion mutters, drunk off of his own knot. “You’re so pretty, you’re so lovely, you’re mine.”
The wave passes like that, Riku whining on his knot and Sion murmuring praises in his ear as he talks about how Riku’s so full of his pups, maybe it’ll take this time. Even though there’s no chance of it happening and they’re both on enough birth control to kill a small child. But it’s nice, being held, living in the fantasy that his alpha is breeding him so they can live out their family daydreams together.
Maybe Maeda Riku’s life is a little unconventional. But being his hyung’s isn’t so bad.
-
Scratch that, this is the worst.
As soon as Sion’s rut is over, they’re sucked back into the normalcy of idol life. Or, as normal as it can get. This means going back to dance practice, which usually Riku honestly quite enjoys. But this time the kids are hellbent on ruining his day and he’s not having a good time.
(Unintentionally, that is. But hellbent on it all the same.)
It’s break time and they’re gathered around Ryo’s phone like a flock of birds stalking the NCT Wish Weverse. Riku hangs off to the side and watches them, a little too tired to get back into the fray so quickly. He’s still getting used to being around all of them again, getting used to all the scents.
“They’ve gotten really good at the Daeyoung memes!” Ryo reports excitedly. “Look, there’s a lot of him as that one wolf howling at the moon.”
Somehow, this gets Yushi’s attention. “As the what?”
“The wolf, hyung,” Ryo says like this is a no-brainer. “Here, I’ll show you.”
Riku flops down against the ground, his eyes slipping shut. God. He’s exhausted. He’s easing back into things, allowed to go slow and take as many breaks as he wants, but the issue with that is that Maeda Riku is not the type to go slow, even when the company tells him to. Their dance instructor and Yushi have been on his back all day about pushing himself, but Riku just wishes he could do more.
“You okay?” Sion asks, leaning down to run a hand through Riku’s unfortunately sweaty hair. Riku lets his alpha towel his neck off, gentle as ever.
“‘M fine,” Riku leans into his touch, unable to stop himself from purring when Sion cups his jaw. “Just tired.”
Sion hums. He isn’t the type to get bossy, not really, so he doesn’t tell him that he needs to rest - Riku, after all, can decide things for himself. But he’s still doting, still likes to hover. Always trying to make himself useful.
“You’re cute,” is what Sion says instead. “I can’t tell you how happy I am to have you back.”
He’s been so sappy recently, sticking to him like a leech with this insufferable smile on his face and soft eyes and grabby hands. It makes Riku shy, makes his face go red. His hyung is so clingy.
Riku smiles, ears pink. “I know.”
Sion has been a little obsessed with him these past few weeks, and so he lets his alpha plop down beside him and bring Riku’s head onto his lap as his insufferably attentive hyung massages his temples. Riku hadn’t said anything about a headache, but he can feel the bare bones of one approaching, and he’s just grateful that Sion somehow already knows that.
Riku’s eyes slip shut again and he purrs, feeling awfully content, all comfy and curled up in his alpha’s lap and letting himself being doted on-
It’s Ryo, of course, who interrupts everything. “They said WHAT about Sion hyung’s abs?!”
Immediately, Riku stops purring and his eyes snap open.
Who the fuck is talking about his hyung’s abs.
Apparently this is all no big deal because Sion just sighs as the maknaes break into giggles. Which only really makes Riku more suspicious as he sits up and looks at the pups.
“Who,” he demands. “Who said that.”
“It’s just a fan, jagi,” Sion says. He drags Riku back down to his lap, stroking his hair. “They’ve gotten passionate about my face, recently.”
“This noona says she wants to lick off your sweat, hyung!” Sakuya calls. “And she wants to smell you, and-”
Riku rises back up in an instant, eyes narrowing. What was that? She wants to do what to his alpha?
“I dunno if we should be reading this,” Daeyoung says, ears red. “They’re getting really explicit.”
That gets Riku’s full attention, because the only person on Earth allowed to say explicit things about Oh Sion’s abs is him. Full stop. Absolutely no one else.
“Let me see,” Riku demands, scent souring just at the idea of anyone else getting close enough to smell his alpha. “What else are they saying.”
Sion huffs a laugh, meanwhile Yushi just stares at him, admonished.
“Are you-” the beta says. “You really can’t be serious right now-”
Even so, the two youngest are quick to obey their pack omega, passing the phone right over to him. Riku takes it with a frown, his disapproval only deepening when sees what the fans have to say about his boyfriend.
There's a lot of thirsty messages. Calling him handsome, hot, pretty; every name in the book. There’s a lot of pictures of Sion, ones where he looks fucking gorgeous, getting reposted and spread around. Riku’s frown deepens as their fans vie after his hyung in every language they can think of, using every phallic emoji under the sun, each post getting way too many likes-
“Where did these people come from?” Riku scowls, unable to stop the little growl that escapes his throat. There’s so fucking many of them; it hadn’t been like this before he left, had it? He would’ve remembered if every Wishzen on the planet wanted to be his boyfriend’s omega if that was the case.
How could he have not known about this? When did this happen?
“God,” Yushi grumbles, snatching the phone out of his hands and scrunching his nose up in disgust. “It’s not a big deal. You smell like a corpse.”
The pups are seemingly unbothered but Daeyoung is pinching his nose and Sion looks astonishingly concerned. Riku doesn’t often lose control of his scent - in fact, he can only remember it happening a few rare times - and so he forces himself to calm down, hackles lowering.
“Riku?” Sion asks, hand on his shoulder. “Are you okay?”
You would think in their line of work that jealousy doesn’t come easily, especially when all of them are constantly paraded around for millions of people to fawn over. And you would think that Riku is incapable of possessiveness when he has an alpha who wouldn’t ever even dream of looking at anyone else other than him. You would really, really think so. Really.
But here’s the thing.
Riku isn’t insecure, he’d be stupid if he was. He has no wavering confidence, not when it comes to his relationship. But ever since he’s come back, there’s been this insane part of his biology that makes him snap his jaw whenever anyone sends his boyfriend meaningful looks, a part of him that makes his usually unrelenting gentleness turn into something ugly.
He feels it when people get too close to his pups, when they bat their eyes at his alpha, when they look too hard at Yushi or Daeyoung. Being a pack omega comes with a certain kind of possessiveness, sure, but it’s a bit weird for someone like Riku. He can be prone to a bit of jealousy every now and again, mostly as a joke, but lately it’s gotten a bit unhinged. He forgets just how far down his jealousy can go when it’s just him and the pack, but then people go around wanting his hyung’s knot on the internet for all of them to see, and it’s like it’s been there all along.
He can’t quite tell if Sion has caught on to the recent uptick in possessiveness. He’s gentle and sweet and caring, but he can be completely oblivious even when Riku’s scent is rank with jealousy. Like how he rubs at Riku’s shoulders while the rest of the group looks at him with acknowledgement in their eyes, as Yushi’s normally neutral expression falls into a frown.
“It’s nothing,” is what Riku says, leaning back into Sion’s chest. He makes his scent go sweet and calm and gentle, pretending like he actually doesn’t care that there’s people online who think they deserve an alpha like Sion. He breathes in; out. “I’m okay.”
He can tell that none of them quite believe him, but Sion has always been easy to please with his scent, and so they let it go. The kids go back on Weverse, albeit a lot quieter this time, not bringing up anything about what the fans think about Sion again.
Riku has some research to do, clearly. Something happened while he was gone to make their entire fanbase fawn over his alpha. His hands itch to reach for his phone but he stays pliant in Sion’s arms, leaning into his touch when Sion smooths a thumb over his cheek.
“Don’t make me worry about you,” Sion sighs. “Tell me if anything’s wrong, okay?”
Riku has always listened to his alpha, of course, but it’s okay if he does a little digging around. It’s okay if he keeps a thing or two to himself. What Sion doesn’t know can’t kill him.
“I will, hyung,” he promises. “There’s nothing to worry about.”
-
Riku enacts his plan while Sion’s in the shower.
Dance practice had gone smoothly even as his curiosity had burned at him, and so he had to wait until he was alone to strike. Sion only really leaves his side for a few precious moments on an average day, so Riku has to act quickly.
“Where did all these people come from,” he mutters to himself, tapping around on his phone. “Who do I need to talk to…”
He starts on Weverse, where he’s assaulted by the same shit he saw earlier. A lot of memes about how handsome his alpha is and how they want him to be their mate or whatever. It doesn’t give him a whole lot to work off of, but it confirms what he already knows - everyone wants his hyung for themselves.
So he logs into his secret Twitter and that one’s a little more helpful, albeit way more unhinged. There’s a lot of people comparing him to a cow, ogling over his chest. From what Riku’s able to gather, Sion gained a lot of popularity during the year-end stages with his dancing and good looks and whatnot. And Riku had known about his alpha’s increase in popularity - and was proud of him, of course! - but now knowing that it lies in thirstiness and these nefarious desires for Sion to claim these random people online as his own has him seething.
How could these fans even think that they have a chance? Did Sion not just publicly call Riku his princess at a bunch of fan events? He’s clearly taken!
Clearly! No one else ever gets to have him!
The tweets he finds get progressively more explicit and Riku reads all of them in a bout of fury, hating the way they ogle over the size of his knot or what he’d be like in bed. They don’t know that gentle giant Sion gets rough if you ask him to be, fucks you like he owns you if you let him. They don’t know how mean his fingers are, or how much he likes the taste of slick, or how demanding he gets when he’s deep in rut, taking you over and over and over-
Riku closes Twitter with a huff. He can absolutely not get hot under the collar just because some fans are right about his alpha having a big knot. They don’t need to know that!
The worst part is that Riku knows that there’s no use getting upset when this is just an inevitability of not only dating an idol but being one, and yet he can’t help but be a little bitter. He missed out on five months of being by his boyfriend’s side while all of these people got to see him flourish on stage, nurturing their own fantasies where Sion is their alpha. Only Maeda Riku knows what it’s truly like to have an alpha like Oh Sion, and it’s just not fair that he has to share Sion with them. He knows that the whole point of his career is to engage in fan service, but he hates that they’re even allowed to publicly thirst after a (secretly) taken man like this.
It’s not like he can go on stage and tell everyone to back off, either. If he had it his way, he and Sion would already have matching bite marks on their necks. Riku wishes he could go online and rave about how good his alpha’s knot is and how no one else will ever get to take it. That would really show them.
(And of course he would never. But that doesn’t change the fact that Riku wants everyone to know that Sion is his.)
So he curls up in his nest and pouts until Sion gets back, wherein he greets his alpha with a smile and pretends like nothing’s wrong, obviously. Because the less his hyung knows, the better.
(…Though that doesn’t mean that Riku calms down about it. Because he doesn’t.)
They head into the last leg of their tour right before the next comeback preparations start and Riku is forced head-first back into the consistent exhaustion of idol life. His body acclimates back to gruelling performances and the bright lights of a concert hall again and Riku’s inner omega is a bitter, bitter thing every time there’s another omega even in their vicinity. He doesn’t know what’s wrong with him. Not to mention that tour itself only makes his jealousy worse - the internet becomes saturated with Oh Sion fancams and his alpha’s fanbase only grows.
Of course it does. He’s only getting more handsome, on top of being tall and strong, which makes everyone want him on principle. Their audience is mostly screaming omegas who want some handsome alpha idol to sweep them off of their feet. They have no idea that Sion belongs to him.
Riku is exhausted, pouty, jealous. It’s not fair.
It’s only natural that he takes action, and maybe - just a little! - plays up the fanservice a bit. It just feels natural to do, sates his inner omega who’s now always howling to claim his alpha as his. He clings onto his hyung while they’re on stage together. Acts a little more brazen than he typically would. Says a lot of things that make their fans squeal and the rest of the members roll their eyes.
“If I was a girl, I’d date Sion hyung.”
“Am I your princess, hyung?”
“Sion hyung thinks I’m the cutest.”
It gets Sion red-faced more often than not, and Riku, who normally acts so shy with his leader, raises an uproar online.
How could he come back from his hiatus so flirty!
Yah, is Riku trying to stake his claim or what?
Damn, he’s already yours! Fine!
(Management pulls him aside to both commend him on the fanservice but also tell him to cool it with the flirting. He toes a fine line, as he so often does, giving their manager an angelic smile as he promises to be more subtle.)
(He does not get more subtle.)
He can’t help it. He wants to gnash his teeth every time a fan leans in close enough to smell. He spends every second he can by Sion’s side, saturating him with his scent and try his fucking best to stake his claim. The members don’t even tease him about it, just merely groan when Riku’s scent goes heavy in the air as he mouths at his hyung’s scent gland. Even Riku can admit that it’s getting a bit ridiculous. His omega’s never been so needy, so out of control before.
So Yushi, naturally, stages an intervention.
Riku is minding his own business, fucking around on his phone, when Yushi pulls him out of the practice room and into the hallway. He doesn’t really get a choice in the matter, the beta tugging him out of Sion’s arms and hissing that they need to talk.
Sion does not intervene, mostly because he’s never all that excited to complain when Yushi gets involved in things. He says it’s because Yushi’s his best friend, but Riku really knows that it’s because Yushi can out-argue any of them.
Coward.
“You,” Yushi frowns once it's just the two of them alone out in the hallway. “You have a problem.”
Riku blinks at him.
It’s not that he disagrees with that sentiment, not really, but it’s so vague that he can’t help but be a little bit offended. Sure, there are a number of things wrong with him, but saying so as a general statement is just mean.
“Did you drag me out here just to insult me?” Riku asks, making a face. “Because you can just do that in the practice room, I’m not gonna-”
“No,” Yushi says, frown deepening. “You’re being insane and I don’t like it.”
Which… alright.
The thing is that Riku and Yushi have always stuck together in a way that they don’t with any of the other members, boyfriends included. Whether that’s cuddling on the couch or ganging up on their alphas, Yushi has the tendency to cling onto Riku’s side and Riku has the tendency to like it when he clings, pouting if his favorite beta in the world doesn’t curl up with him on the way back from long shooting days. They’ve disagreed just about never and Yushi has always listened to Riku better than anyone else, and yet he’s got that frown etched all over his face like something’s really bothering him-
“What’s wrong?” Riku asks, scent going gentle. “What am I being insane about?”
If he expected his best friend to be nice about this, he is sorely mistaken. Yushi’s frown goes hard. “Your jealousy over Sion,” he says, “is getting out of hand.”
And… ah.
Okay. Yeah.
He probably should’ve seen that one coming.
“What are you talking about!” Riku exclaims, scent going sharp and his face immediately turning red. Sure, the scenting was obvious, but he didn’t think the members would actually realize just how possessive he’s been getting, even if it was pretty blatant that they caught on. “I’m not jealous of anyone!”
Yushi’s expression turns pained. “You won’t stop calling him your prince,” he says. “And clinging onto him, and calling him handsome, and-”
Someone in management passes by in the hallway and gives them a weird look. Probably thinks they’re fighting or something, which is just great. As if Riku doesn’t have enough on his plate as it is.
“That doesn’t equate to jealousy!” Riku hisses the second the staff member’s out of earshot, even though it most definitely does. “It’s just fanservice!”
Yushi pays no mind to Riku’s efforts to stay quiet. “You can’t call it fanservice if you’re basically scenting him on stage!” His voice gets a little louder, looking a little upset. “He’s already yours, Riku! It’s so unnecessary!”
While Yushi is infamously stubborn and has the tendency to get impassioned over the oddest of things, such as one’s favorite brand of instant ramyeon, the rise in his voice gets Riku to settle. Riling Yushi up never leads to anything good - he can hold grudges that last for months. Riku speaks from experience.
(The pre-debut ice cream incident scarred many of them, and is the sole reason that neither Sakuya or Ryo are willing to share a hotel room with their beta.)
So Riku knows when he can’t argue anymore, huffing out an exasperated sigh, willing for his scent to calm down. Yushi is right, whether or not he wants to admit it. He’s been acting like a crazy jealous lunatic on stage and it wasn’t hard to notice; Riku hadn’t been like that before he left. He can get away with the notion that he missed his pack, but being outwardly possessive for all their fans to see will get him into trouble.
“I guess you’re right,” Riku grumbles, conceding. He doesn’t like arguments, especially if they’re with Yushi. Part of his job as pack omega is to help keep everyone’s feelings in check, after all.
Yushi looks at him closely, the hard furrow of his eyebrows softening. “I’m always right,” he says automatically, not really joking. And then he sighs. “I just… I don’t get it. He’s already yours.”
And that, admittedly, is true; Sion is his. Always has been, always will be. He’d be a complete idiot to not realize that. But his inner omega has gotten so vicious recently, determined to stake his claim on his favorite alpha. To a degree where it’s starting to scare him, a little bit, because he wasn’t aware that he was even capable of these kinds of feelings. Not when his relationship is so secure and there’s never been any room to doubt just who Sion belongs to.
Sion loves him more than anyone. That much is obvious. It’s always been obvious.
So Riku sighs, too, running a hand through his hair. “It’s not really a big deal,” he says, avoiding Yushi’s eyes. “But hyung has gotten a lot more popular since I’ve been gone and maybe it’s making me a little insecure.”
He really hates to admit it; after all, Riku is confident. He loves his members and himself and his relationship. But the past few months have been really hard, have left him feeling so lonely after such a long time of being surrounded by his pack, and this whole thing is just… a little hard to handle. It’s made his omega unruly. That’s the only explanation for it.
“There’s nothing for you to be insecure about,” Yushi says, being unsurprisingly sincere. He always treats Riku more gently than he treats the others. “Hyung only looks at you.”
That, at least, gets Riku to smile. “I know,” he says. “He really does.”
It’s true that Sion won’t even give a single other omega a spare glance unless it’s in a friendly way, and it’s true that even the older NCT hyungs will comment on it - yah, Sion’s so whipped for you, Riku! And Riku knows all of this, obviously, because ever since they were paired up for their cycles, Sion only ever has looked at him like Riku is his. And it’s nice, being his, being his hyung’s. But the bitter part of him is greedy and wants more.
He wants a mark. He wants something tangible. He wants Sion’s teeth sinking into him - his alpha always refuses to leave marks even where people can’t see, always so cautious - and he wants Sion to be his alpha in every sense of the word. He wants to do whatever it’ll take for it to happen. He wants everything…
“I’m just worried about you,” Yushi says slowly. “You just came back, and now you’re acting weird…” His hands fidget by his sides. “Are you sure that it’s not because something’s wrong?”
Ah, Yushi. Always so worrisome even though he pretends he isn’t.
Riku takes his best friend’s hand. “Nothing’s wrong,” he promises. “I’m just being stupid, is all.”
That’s simplifying things, maybe, just a little white lie, but Yushi cracks a smile.
“You’re always stupid.”
He really tries to calm down after that, holding his tongue when he wants to announce to the world how his hyung is his. He hangs off of the other members, not just Sion. He holds back from complimenting his alpha at every given opportunity. He reels his jealousy in, trying to be normal about it. His omega howls in defiance in his chest, snapping its fangs, but he really tries. Really, really tries.
Comeback preparations go more smoothly and Riku spends a lot of time in his nest, curled up with his alpha and saturating him with the scent of orange blossom. He spends a lot of time thinking, and also trying not to think at all. He has a job to do and this is all one big distraction.
It can't be that hard, being normal. Sion has always been his and he always will be. Riku has virtually nothing to worry about and he knows it, so he wills his inner omega to settle down and stop getting so rowdy whenever a fancam of his boyfriend goes viral online. Which, of course, doesn’t work. But he tries his best.
It’s just a part of the job, he tells himself. It’s just a part of the job.
It works, kind of. Riku reels himself in. Acts normal. Acts like himself. Sion gains popularity and he, like, doesn’t even care. He doesn’t care at all. His omega is mad but that’s fine, because if there’s one thing Riku can handle, it’s his whiny inner omega.
“Good morning, princess,” Sion mumbles into his temple as they wake up on another busy shoot day, tugging Riku close.
Riku presses their cheeks together and thinks mine, mine, mine. Says, “good morning, hyung,” and kisses his boyfriend awake.
Sion laughs into his mouth, pleased. Surely Riku can do this.
-
He lasts, like, two weeks.
Comeback promotions roll around and they’re brought into the full swing of things, shuffling from one music show to the next with their new mini album. It’s exhausting, and Riku clings onto his members in a last-ditch attempt to take on some of their strength and resilience. He kind of forgets about the whole jealousy thing before it’s coming back at full force.
In his defense, it’s an accident. Kind of.
Sion and Yushi are in charge of doing challenges with other groups and Riku takes on the role of cameraman mostly because he kind of doesn’t want to leave his alpha’s side while he’s on edge from exhaustion. Most of the groups at Mubank today are rookies, newly debuted, who look up to them as sunbaes. It’s sort of weird because it still feels like they only just debuted themselves, but he supposes it kind of nice to be admired by their dongsaengs.
That is, until an omega from today’s newest boy group finishes their dance challenge and turns to Riku’s alpha with intent.
He looks up at Sion with stars in his eyes - they don’t even know this kid’s name! - and it’s fine, kind of, but then he’s asking Sion sunbae for advice as a leader, scent going sweet and coy as his arm brushes against Sion’s. Which, decidedly, is not fine.
His scent blooms on purpose, trying to be enticing, and Riku hates it because he would do the same. Any sane omega would see an alpha as tall and broad as Sion and put their neck on display, pout their lips, try to appear small and submissive or whatever bullshit their inner omegas inspire them to do. Anyone would, but Sion is Riku’s, and it’s not fucking fair-
Riku smells his own scent burning in the air before he even realizes that he’s upset. Rotting orange blossom, smokey and sour. Yushi is the first one to notice, turning to him with a sharp glare.
“We’re in public!” He hisses.
Riku’s face burns. “I know!”
It only takes a second longer before the whole hallway smells like him, causing the rookie group to plug their noses. Sion’s attention immediately shifts to him.
“Riku?” He asks. “What’s wrong?”
Riku, who is too busy trying to calm his scent down, doesn’t know what to say to that. He very obviously can’t tell the truth - that omega wants to fuck you and I’m upset because you’re mine. No, he can’t say that. Not here, at least.
So he does the well-adjusted thing and deflects.
“Must be my cycle or something,” he mumbles, face bright red as the rookie omega looks at him in disbelief. “Sorry, hyung, I didn’t mean to-”
“Your cycle?” Sion asks. He stalks over to Riku’s side to put a hand against his forehead and scents him with his wrist. It’s shameful how quickly Riku’s scent blossoms with something sweet once his alpha’s touching him. “If it’s your pre-heat, we should get you into the nest.”
The rookie omega’s expression turns a little shocked as Sion peels back his scent patch and runs his nose over his scent gland, cursing how useless the damn thing is when Riku’s close to heat. It’s… it’s a very blatant thing to be doing in public. But it makes Riku’s omega purr in delight because obviously an alpha would only fawn over him like this because they’re together.
“Oh-” The rookies omega stutters. “I didn’t-”
Yushi pinches him on the hip when Riku grins, the rookies mumbling out excuses and bowing before they scurry away. He must be really close to his pre-heat, actually, because normally he’d at least feel bad about it. And normally his omega doesn’t get so vicious over his alpha being looked at, or at least not to the point where he can’t control it…
“Let’s go back to the waiting room,” Yushi sighs. “You two are the worst.”
They get a scolding from the social media noonas for having to cut their challenge circuit short, but Yushi does aegyo to get them off their backs, which somehow works. Sion fusses over him, tucking Riku into his side. He’s not even in his actual pre-heat yet, but Sion always gets overbearing the second he knows that Riku is close. Riku clings onto Ryo as his alpha scents him furiously.
“Do I have to be here for this,” Ryo grumbles, but lets Riku hold him close and bury his face into his shoulder.
“It’s because you’re my favorite,” Riku tells him, ignoring how the swipe of Sion’s wrist over his neck gets his omega perking up with interest. And when Sion goes to use his mouth: “hyung, stop!”
“What? I’m just scenting you!” Sion frowns, even though he was definitely going to do more than just scenting if he even considered putting his mouth anywhere near Riku’s neck. “You’re getting close to pre-heat and we’re performing in an hour!”
Ryo squirms, not wanting to be a part of this. Riku does not let him leave.
“I’m cuddling with my pup,” he complains. Ryo’s milky pup scent eases his omega even more than Sion’s espresso does, and he really, really will do something stupid if Sion so much as kisses him. They have a performance soon and he’s not willing to jeopardize himself so soon after returning from hiatus.
“You don’t want to be scented?” Sion asks, looking genuinely put out. Riku’s omega yearns to soothe him, but his brain knows better than to give in.
Riku’s ears burn. He nudges his alpha away.
“Later.”
Sion listens, at least, though he sticks close by with his arms crossed over his chest. Riku manages to drag Sakuya into cuddling with them, who leans happily into Riku’s side as he shows him some of his favorite TikToks. The kids have always been drawn to him when he’s getting close to his cycle, once his scent goes all sweet and motherly. Though they like to pretend that they aren’t.
Sakuya and Ryo get into a squabble about what their next dance challenge should be and Riku curls up between them, closing his eyes. Sion slinks away to go to the bathroom and Yushi and Daeyoung return from where they were probably fucking around in a coat closet somewhere (Riku can’t complain as he does that very same thing often), and he’s just about to drift off to sleep when there’s a very loud group of grown men breaking into their practice room with a camera crew.
“Maknaes!” Haechan peeks his head in through the door, “are you all decent?”
Oh, right. Riku completely forgot about the Dream hyungs being here today. They’re supposed to… supposed to film something…
“Hi, hyung,” Riku says with a strained smile before his brain can whine about how much he doesn’t want a camera pointed in his face. He pulls the maknaes up with him, ready to do their greeting.
“Yah, Riku-ah, are you okay?” Jaemin asks, shoving Haechan out of the way and frowning. “You look pale. We don’t have to film if you’re sick.”
The rest of Dream is peeking their heads in behind them and Riku suddenly blushes under their attention. He knows he smells kind of unsteady, but to be looked at so closely…
“Sion hyung will be back soon,” Ryo offers. “We can film then!”
For not the first time, Riku thanks god for his saint of a maknae. He bows robotically as Dream piles into their waiting room to wait for the baby alpha leader (or, at least, that’s what Jaemin calls him) to return. Everyone had gotten close to each other during the year-end stages and SMTOWN, so Riku is a little… well. He feels like a bit of an outsider.
The only one who doesn’t seem ready to dive head-first into excited conversation is Jisung, who shuffles around like a nervous rodent. He’s gotten close to Sion, recently, and since Riku is Sion’s mate, he really should at least say hi.
“Jisung-ssi,” Riku stutters in greeting. “Um, hi. It’s nice to, um. Meet you…”
God. He’s really not good at this when Sion’s not around.
“Riku,” Jisung bows his head. “Hi.”
He doesn’t elaborate any further than that. And, well. Riku is really trying his best. If he had known that Jisung was even shyer than he is, he wouldn’t have even opened his mouth.
“Hyung told me about you,” Riku tries. “You got close? On AWSAZ?”
That’s partially a lie, because Sion never said anything more than how he and “Jisungie” started to hang out. Jisung is another alpha but he’s just about as intimidating as Ryo is, which is not even a little bit. His scent is dull, but surprisingly floral and sweet for an alpha.
“Yeah, Sionie and I text,” Jisung says, nervously scratching at his neck. “We went out to eat the other day, it was nice…”
His voice trails off.
“Hyung is really nice,” Riku says for a lack of anything else. “He’s really-”
Jeers start up when Sion opens the door to twelve people waiting on him. He’s immediately nagged at by the hyungs - what took you so long! - and the maknaes alike - Sion hyung, were you pooping? It’s ridiculous how that last accusation gets a rise out of everyone, getting them all to laugh. Sion looks at them like a deer in headlights, eyes falling right on Riku.
“Oh,” he says. “Hi.”
Riku grins. He sees Sion’s eyes look between him and Jisung, where they’re sitting on the couch together. They’re not even touching, but Sion’s eyes narrow.
…Interesting.
Riku tries to pretend like he didn’t notice anything at all.
They start filming and Sion is held hostage by the hyungs as they force him to talk to the camera. Riku and Jisung sit off to the side and watch them, amused. Jisung stops fidgeting and he even laughs when Chenle cracks a joke about wanting to play against Wish in basketball. Renjun and Ryo are taking a selca together and Mark is trying to get Yushi to join them on camera and Jeno and Daeyoung are stuck staring at each other, both looking like very polite, well-behaved puppies. Sion’s eyes keep darting towards Riku, and Riku tries really, really hard to act like there isn’t an evil plan forming in his mind.
Because the thing is that while Riku likes it when Sion gets jealous (he likes it a lot), he never does it on purpose. Besides the whole breeding kink fiasco, Sion doesn’t actually get possessive very often. Overbearing, sure. Way too attentive, definitely. But unless a sunbae starts making weird advances, Sion usually doesn’t try to make a point of behaving like Riku’s alpha, let alone in front of the other NCT members. He’ll act really doting when he thinks the hyungs aren’t paying attention (except they always are) and turn red-faced when they start wolf-whistling about how whipped he is. Which Riku always found cute.
However…
It’s weird, because Riku remembers not wanting to be kissed even just a half hour ago. And he remembers that being the smart thing to do. But the thing is that when Riku’s in pre-heat, the rational part of his brain slowly starts to turn right off without him really noticing. So what’s wrong with kissing? What’s wrong with teasing hyung so he gets in trouble and gets taken apart by his alpha? What’s wrong with getting scented and devoured and fucked so hard he sees god?
That’s probably why he doesn’t even question it when his omega tells him: make him jealous. That’s probably why he asks Jisung, “is it okay if I call you hyung?” That’s probably why he leans in just the tiniest bit closer with a shy smile when Jisung says, “yeah, sure.”
Riku can only smell it in the air because they’re pack and as good as mated, but there’s the barest hint of burning coffee coming from his alpha.
Riku should really feel bad.
(But he really doesn’t.)
They’re running out of time before Dream has to head on stage, so the two groups huddle together for a photo with the agreement that they’ll get some dance challenges done afterwards. Sion beckons Riku over to him with the tilt of his head, expectant look in his eyes. With Riku so close to pre-heat, he wants him to stick close.
(Riku just smiles at his hyung and leans in Jisung’s side, posing for the photo with a peace sign, leaving his alpha all alone on the other side of the frame.)
He knows he’ll get in trouble - a lot of trouble - and he knows that he’s playing with fire because his alpha can get really mean if he wants to be. But he can’t help the temptation of it, not when Sion punishes him so deliciously. His inner omega yearns for it. So when Dream leaves, he coos, “bye, Jisungie hyung!”
Jisung’s ears are red. “See you, Riku-ah.”
Without the chaos of Dream with them, the waiting room goes blissfully silent for about two whole seconds. But then Sion is stomping over to Riku’s side and he watches, delighted, as the rest of the group very pointedly turns their eyes away from them.
“Hyung,” he greets, scent sweet.
“Jagi,” Sion says. His voice is low, scent slowly sharpening. “Did you get close to Jisungie?”
Riku knows that he’s being given an out, because Sion never gets actually upset. It wouldn’t be fun if he did. But the thing is that he doesn’t want an out, doesn’t want to back off. He wants whatever his hyung can give him. The last rational part of his brain melts away as his omega takes over and whispers in his ear: say it.
So:
“Jisungie hyung was really nice,” Riku grins.
Riku is so rarely ever bratty on purpose because he likes being good, believe it or not. He loves being his hyung’s well-behaved princess and he likes all the praise and nasty things Sion says to him when he’s polite and sweet and pliant. But it’s just too tempting, to be taken apart like he has no choice. Like Sion owns him.
“He’s your hyung now?” Is all that Sion asks, gaze sharpening. He takes Riku’s hand in his and rubs their wrists together. His scent grows stronger.
“Yeah,” Riku smiles. “I have more than just you, now.”
Sion’s scent turns bitter in the air and it’s Yushi who tells them to get out. He’s pulled towards the infamous Mubank closet and only hopes that his groupmates didn’t leave it a mess.
“You,” Sion hisses in his ear, “are in so much trouble.”
-
The second they’re alone inside the damn closet, Sion has him pinned to the door, slotting up right against his back.
“I can’t fucking believe you,” Sion growls. He gets a fist in Riku’s hair, tugging his head back so his back arches all by itself. “I thought you were good, baby.”
“I am good,” Riku moans when Sion ruts against him. This is dangerous, considering how soon they need to go on stage, but he can’t help the thrill that goes up his spine. “I didn’t do anything wrong, hyung is being-” he moans again. “Hyung’s so mean.”
Sion chuckles but there’s no humor in it. His fingers are nimble as he undoes Riku’s jeans, pooling them at his feet and spreading his thighs with one leg between Riku’s. Grip on his hair tightening when Riku tries to grind down on him.
“You’re the one who’s going around collecting alphas like they’re Pokemon, princess,” he says in Riku’s ear. “What, hyung’s not enough for you? It’s not good enough that I’m the one who keeps you as full as you want, always keeping you sated?”
Riku’s head is a little fuzzy. He can feel his pre-heat coming on, the slow buzz of it. His omega wants to listen, wants to be good for his alpha, but his brain still wants his hyung to be mean. Still wants it so good that it hurts.
“No, I-” he stutters. “I love you, hyungie, ‘m yours-”
Sion grips his hips tightly, digging into his skin. “Are you, baby?” He asks. “‘Cause last time I checked, you thought one hyung wasn’t good enough.”
His hand snakes around to rub at Riku through his briefs and Riku moans, his alpha’s fingers so rough and mean as he circles his clit. He’s so wet that he’s definitely going to get into trouble for getting slick on his wardrobe, but he can’t help that his hyung makes him drip. He can’t help the way he arches his back and spreads his thighs wider, begging for more.
“Hyung,” he moans, brain a little hazy. “I-”
“You’re so fucking wet,” Sion mutters. “Bet you’d want Jisungie to hear you like this, hm? But you’re mine.”
Riku doesn’t even know what to say to that because no, he doesn’t want Jisungie to hear. He’s only ever been hyung’s, only ever been wet like this for his alpha. He mewls, squirming.
“No,” he pants. “‘M yours-”
“You are,” Sion growls. “Fuck, no one else gets to have you.”
Sion tugs his briefs down his hips and gets Riku’s cunt exposed, all wet and dripping. He’s getting his stupid slick all over Sion’s pants but Sion doesn’t move, doesn’t even scold him, just thumbs at his clit and mouths at Riku’s scent gland.
It feels so good, so wet that it’s almost frictionless. Riku’s hips twitch as his clit gets played with so roughly, not used to how meanly Sion touches him. He’s normally so gentle unless they’re in their cycles, cooing at Riku until he comes. This is so different, so-
Not better, exactly. But it’s good.
“Oh,” Riku whines. “Hyung, please.”
He doesn’t know what he wants anymore - doesn’t know if he should be good or bad. Sion decides for him, because his alpha always knows what he needs. Always knows how he’ll like it.
“You could come like this,” Sion says, voice low. “You could come just for hyung touching your pretty cunt but you still want more, hm?”
“Want you inside,” Riku drools as Sion’s fingers tease his hole. “Please, hyung, please.”
“You’re so bad,” Sion growls, and slaps down on his clit. Riku’s wail gets cut short as Sion stuffs his fingers into his mouth, gagging him and making him take it. “I thought you were hyung’s perfect angel, but you’re going around with other alphas, calling them hyung-”
“Please,” Riku tries to say. Tries to beg. Sion’s fingers in his mouth makes it impossible and all he can do is drool, Sion pressing down on his tongue.
“Jesus,” Sion groans, fingers getting rougher. “How are you so wet? Are you that desperate, honey?”
Riku has never felt so fucking helpless before. Doesn’t know what else to do as he sucks down on Sion’s fingers and nods his head. Moaning when Sion’s teeth scrape over his scent gland.
“Want it inside?” Sion asks, pressing closer. “Want to be full?”
Riku’s eyelids flutter closed and he nods again.
Sion grumbles out a fuck as he lets go of him just enough to undo his buckle, tugging his boxers down and his cock slapping down against Riku’s lower back. The threat of it makes Riku feel insane, the promise that he’ll be full.
“When I fuck you,” Sion says, “you’re going to tell me how good hyungie feels inside you, and you’re going to tell me that the only hyung you have is the one who owns you.” He spreads Riku’s cheeks and doesn’t let go until he clenches. “Am I clear, princess?”
Riku nods again, mindless. Not knowing anything else besides what his hyung tells him. Sion’s fingers slip out of his mouth and he moans when Sion spreads his thighs wider.
“Hyung,” he mewls. “Please.”
“Jesus,” Sion mutters. He guides himself to Riku’s hole and sinks inside.
The stretch is so fucking good. So good and familiar that Riku aches. He doesn’t know what to say as Sion buries himself to the hilt. Doesn’t know anything other than his hyung inside him.
“If you stop talking,” Sion warns, voice low as he fills him up, “I’m pulling out and leaving you here. Okay?”
Riku whines. “Okay.”
Sion slides out, slides back in. Teeth grazing his scent gland.
The pre-heat makes him a little dumb in the head. They don’t often fuck until he’s in actual heat because having sex can make him prematurely yearn for a knot while he’s still in the early stages of it. It’s not fair how easily Sion just owns him, but it feels so good. So, so good.
But Sion growls. “Start talking.”
And Riku, of course, listens.
There’s an urgency in him that Riku’s never felt before, not during sex. “You’re my- you’re my hyung,” Riku moans, drooling. “I’m yours and there’s no one else-”
Sion hits his sweet spot with pinpoint accuracy, getting him clawing at the door. Fuck. Fuck, it’s so fucking good.
“I love it when you’re inside me, love being owned,” Riku stutters. “I dunno what it’s like besides you, don’t want anyone- anyone else-” he gasps when Sion’s grip turns tighter and his thrusts get meaner. “Hyungie, it’s only you.”
“Only me,” Sion growls. “No one else.”
“No one else, love being your princess,” Riku babbles. “Only wanna be hyung’s, only good for you.” Sion mouths at his scent gland it gets harder to breathe, their scents so thick in the air as Sion fucks him rougher and rougher. “‘M sorry for being bad, I just- just wanted you to punish me-”
“You couldn’t help it, could you,” Sion groans. “You can’t stand it if hyung doesn’t look at you for even a second.”
“That’s not-!” Riku cries. “I’m not-!”
Sion spreads his thighs wider, fucks into him harder.
“Isn’t it, baby?” He growls. “You asked for this.”
He did, is the thing. He asked for it and begged for it and wanted it so bad that he pulled poor Jisung into his scheme. Riku can’t even argue because this is all he’s ever wanted, his hyung belonging to him and inside him and owning him.
“Oh my god,” Riku wails, trying to be quiet but failing miserably as Sion bullies his poor, poor cunt and fucks him with this obscene wet slapping sound that only makes him even wetter. “I don’t- ‘m sorry,” he sobs. “‘S only you, hyungie, I don’t want-”
His back arches when Sion’s fingers find his clit again and circle him roughly, pace mean and rough.
“Don’t-!”
“You don’t want it?” Sion asks, voice condescending and cruel. “Feels too good?”
“Oh, god,” Riku wails again. “Feels so good, hyung, ‘m so wet-”
He should probably be more cognizant than he is right now, but the thing is that hyung’s cock in him and hyung’s fingers playing with him feels so good that he’s just melting into a puddle of needy, needy omega. It’s the best thing in the world, when hyung touches him and fills him and plays with him like he owns him. It’s Riku’s favorite thing.
(If Riku was self aware, he’d scold himself. Cock is not his favorite thing! But pre-heat Riku is too drunk on pheromones to know any better.)
“Who owns you?” Sion growls. “Who’s the only one who owns you like this?”
Riku can’t help but cry. He’s so wet and dizzy and the desire is thrumming in his veins and he feels like he’s never been taken apart like this, not outside of his heat. It makes him feel like he’s going to pass out and die.
“Hyung owns me,” he moans. “There’s no one else.”
Sion’s fingers get meaner. “Which hyung?” He asks. “Do you have more than one, baby?”
Riku feels his sanity slipping little by little, haze of pre-heat taking over him. “You’re my only hyung,” he cries. “My alpha, my alpha, please, ‘m yours-”
Words aren’t even making sense anymore, just babbling whatever comes to mind. He’s never felt so mind-numb, has never just taken it like this. It feels like he’s in heat even though he knows he’s not, feels like he’ll die if he comes.
“Would you let me fill you up before we go on stage?” Sion asks, voice a growl. “Would you perform while you’re full of me, princess? Would you tell all the fans who owns you?”
“Yes,” Riku cries. “I- I don’t-”
“What will you tell them, baby?” Sion presses against him so hard that the door groans. “How’re you gonna tell everyone that you’re already taken?”
Riku’s so close, from Sion’s fingers on him and his filthy, filthy words and the feeling of being used like this. His orgasm feels like it’s going to fucking hurt when it hits, feels like it’s going to fucking kill him.
“‘M Sionie hyung’s,” Riku drools. “I’m not- no one else can- there’s-”
Speaking is too hard. It feels too good. He’s so deep in his pre-heat that he can’t think of anything other than being filled and owned.
“Too close to speak, baby?” Sion growls. “Feels too good?”
Riku’s so close that it hurts, so close that he can’t even think. Sion tugs on his clit and his throat makes a pathetic gurgling sound and he nods, brainless.
“Say thank you when you come,” Sion tells him. “Wanna see how polite you are.”
All it takes is another slap down onto his clit and Riku crumples in Sion’s arms, knees buckling. He comes without even meaning to, comes so hard that he definitely squirts all over this stupid door. Words are impossible, but he cries, “thank you, hyungie.” Says it again when Sion stands him back upright and fucks into him harder. Says it again when Sion comes. And again when he’s filled. And again and again.
“Thank you,” Riku babbles, mindless. “Thank you, thank you, love you, thank you, hyungie-”
“Fuck,” Sion says when he slips out. “I fucking broke you.”
Their clothes are a complete lost cause and Riku’s too high on the feeling of being filled in his pre-heat to do anything other than sink to his knees and mouth at Sion’s soft cock. His omega has taken over him, unable to think about anything other than how he wants it again and again and how hyung always makes it feel good. Hyung is his. Hyung is his.
“Hyung,” he says, eyes pleading. “You’re mine. Want more.”
Sion stares down at him with wide eyes. Laces his hand through Riku’s hair.
“Holy shit,” he says. “We gotta get you home.”
-
Riku is having the worst pre-heat of his life.
As it turns out, having sex was actually a pretty terrible idea. Riku is quite literally cock drunk or something maybe even worse, out of it and heat-dizzy and possessive, completely unfit to perform or work or appear on camera in any capacity. The other four have to go on stage alone without notice and the only reason Sion isn’t forced to join them is because Riku literally refuses to let go of him. Like, the managers try to separate them but Riku starts kicking and (almost) screaming and it’s deemed a lost cause. So Riku has single handedly ruined their award show run and he’s barely cognizant enough to realize.
Sion acts oddly level-headed about the feisty omega sticking to him like a leech, only placating him with soothing hands and gentle praises because anything else only makes him more combative. More, hyung, Riku begs. Please, you’re mine, I want more. But hyung holds him close and tells him later, baby, later…
It’s so out of character, Riku being incorrigible, and no one knows what to fucking do because he’s the only one out of their three presented members who’s actually pretty calm and nice and obedient during his usual cycle. But he’s not, not right now, because a coordi noona hands Sion a new change of clothes and Riku’s teeth start gnashing. He doesn’t let his hyung walk around unless he reeks of him, unless everyone can tell just who he belongs to. Hyung should be covered in his slick, something potent so he’s marked.
You’re mine, Riku mumbles as his alpha holds him close. You’re mine, you’re mine…
I am, Sion hums. Yours, honey, all yours.
If Riku wasn’t damn near feral, circling his mate like a shark, he’d be deeply ashamed. He’s never been this needy even once in his life. His omega is angry - that’s never happened before - and possessive and horny and mean. His brain thinks hyung, hyung, hyung, and his mouth says need you, hyungie, you’re mine, and it’s so bad that they throw Sion’s hoodie over their heads so they can get to the car without any cameras being pointed at them.
Manager hyung clicks his tongue when Riku curls up in Sion’s lap - his inner omega does not care about wearing a seatbelt - but Sion only holds him close, close, close. I’m yours, I’m yours, I’m yours.
Things don’t get easier when they get back to the dorm. Riku squirms at Daeyoung’s scent. He outright refuses to let Sion leave his sight, unwilling to leave his alpha by himself for even a second. Sion dresses them both in new clothes, but Riku’s still leaking slick like he can’t fucking stop. It gets him needy, whiny, upset. Tainting his arousal with irritation.
Sion gets him to the heat room and makes his best approximation of a nest, because apparently Riku doesn’t want to fucking make one. Sion tries his best but it’s messy and uncomfortable and Riku is needy, whiny, upset, once again. He’s busy clinging onto his alpha and growling every time someone else pokes their head into the room to make sure Riku hasn’t, like, mauled his mate to death.
(Need you, he whines, leaking slick over the sheets, scent heavy with anger and desire. Hyung, you’re mine, I need you.
Sion keeps his voice gentle, careful, loving. Later, princess, just hold on a little bit longer.)
It doesn’t take long for anyone to figure out that there is something deeply, deeply wrong. A doctor from the company shows up the next morning.
“It’s because you were apart for so many of his heats,” she - a beta - explains from the doorway because Riku won’t let her get any closer to his hyung. “Normally distance would be no issue, but sometimes we see this in omegas who are…” She hesitates.
“Who have strong personalities?” Sion tries.
She smiles and shakes her head. “Omegas who are very attached to their alphas. It means you’re extremely compatible, Sion-ssi. You two probably should’ve been tested before you were separated.”
That makes Sion sigh, smoothing a hand over Riku’s hair. Riku is too busy glaring at her and leaking slick onto Sion’s lap to be much help.
“Sorry,” Sion says. “He’s usually really sweet and gentle…”
“Don’t worry about it,” she waves him off. “He’ll be back to normal after the first wave of his heat passes.”
So Riku’s cramps start up and Sion just holds him close. He refuses to let his mouth leave Sion’s scent gland, only letting up when the kids stop by to observe and he purrs, a little, at the sweet milky pup scent. The pups were really worried Riku got sick again, but they ended up being more grossed out than anything else because Riku is unbearably horny and you can smell it from a mile away.
The doctor said that penetrative sex is off the table until his actual heat because it’ll get Riku unbelievably needy for a knot, and so Sion makes him come with his mouth and his fingers until his pussy’s all sore from getting eaten out and nibbled on. The orgasms make Riku all docile and sweet until he realizes that they’re not alone in the apartment (what if someone tries to take his hyung away!) and he gets all territorial again.
His poor, poor alpha. He doesn’t complain, not even once.
Sion soothes him, with his low voice and gentle hands. Riku edges so close to heat that it hurts. So close that his body feels like one big cramp, ready for a knot and nothing else.
“You’re mine, hyung,” Riku pants when his cramps hit harder, harder, harder. “You’re mine, I love you, no one else can have you-”
“I’m yours, baby,” Sion coos, patting down his back. “No one else gets me besides you, hm? Wanna come again?”
And then he gets Riku panting for another reason, whining once Sion’s mouth is on his clit, drinking up his slick. “Mine,” Riku mewls, mindless. “Mine, mine, mine…”
His omega is angry. His omega freaks the fuck out if his hyung has the audacity to let go of him. His omega loses its shit if Sion isn’t covered in orange blossom, if Sion isn’t completely his. Sion makes him come. Makes him so worked up that he won’t shut up, won’t stop babbling how hyung is his and it feels so good and he needs more and more and more. Riku doesn’t know anything anymore besides that Sion hyung belongs to him. Doesn’t know anything besides the fact that he’s on the precipice of heat and he might die from how good it feels when alpha knots him. Can’t think of anything else after that.
Riku is normally so sweet and gentle, using his low, soothing voice to calm everyone down when they get keyed up. He’s normally so pliant and kind and ineffably easy-going. Teasing, but only a little bit. Mostly just kind. So, so kind.
Riku doesn’t feel kind anymore. He feels like he’s losing his mind, his omega telling him that he can’t rest until his alpha has bred him so thoroughly that no one else could ever take him away. His omega tells him that his alpha needs to stay close or another omega will try and steal him. His omega only ever shuts the fuck up when Sion’s mouth is drinking up his slick and groaning into his cunt: you’re so fucking good, I’m yours, give me another.
It takes two days, but Riku slips into heat. He slips into heat and his starvation for his hyung and a knot increases tenfold. It’s insanity. He feels insane.
He’s never been more starved for his hyung in his goddamn life, determined to take his knot until he’s full and bred and pliant on his cock. And if there’s one thing about Maeda Riku, it’s that he’s one passionate motherfucker - he’s not going to stop at something until he gets it.
-
The second his heat hits, Riku very suddenly feels unstoppable. Sion doesn’t even notice the change because Riku’s already straddling him the second he’s not cramping anymore, eyes gleaming.
“Hyung,” he growls. His voice is low, firm and unyielding. “Hyung, need you.”
“Hyung’s here,” Sion smiles. And then he’s yelping when Riku pounces and he’s toppled right over.
Riku isn’t weak or frail, not in any sense of the word, but even he can admit that he much prefers to be manhandled and forced to take a knot while he’s in heat more than anything else. And yet his inner omega isn’t satisfied until he has his alpha pinned down into the nest by the shoulders, Riku perched in his lap victoriously.
“Mine,” Riku growls. “My knot, hyung.”
He’s never felt so lost in the emotions of his inner omega before - normally Riku’s the member of their pack who has the most control over the less savory characteristics of his sub-gender, especially when compared to a baby alpha like Daeyoung and a more emotionally driven pack leader like Sion. And yet there’s adrenaline pumping in his veins, filling him with a kind of desperation he’s never felt before. If he wasn’t half out of his mind, he'd be terrified.
But alas.
“You want hyung’s knot?” Sion asks, tone gentle, looking up at him with wide eyes. Most alphas would be threatened by an omega trying to take control while in heat, but Sion only looks… concerned, maybe. A little worried. “Are you with me, baby? Or are you lost up there?”
Riku, in the haze of his heat, doesn’t know what to say to that. His throat lets out a growl and his teeth ache to snap, and he just wants to be fucking filled.
“Hyung’s knot is mine,” Riku seethes. “My alpha. Need it in me.”
That’s probably not the answer Sion wants. He tries to sit up, but Riku doesn’t let him. He presses him down harder - as hard as he can, teeth gritted - and Sion fills the air with soothing alpha pheromones as his expression softens.
“You’ll get your knot, baby,” Sion says, low and kind. “It’s just for you. Can you let me up? I wanna make it feel good.”
“Like this,” Riku insists. He grinds down against Sion, feels slick drip out of him. “Only like this.”
Sion nods, smiling. He slides his hands to Riku’s hips.
“Like this, sweetheart,” he hums. “Hyung will do whatever you want.”
The promise of that is too good while Riku’s so deep in his head, too concerned with owning his alpha to think about much other than his favorite knot and getting bred and making sure he and his hyung get to make pups together. He rocks down on Sion, his aching clit dragging over the bulge in his sweatpants, too focused on the pleasure to even take them off.
“My knot, my knot, my knot,” Riku mutters, teeth gritted, rocking himself down harder.
“I’m yours,” his hyung promises. “This knot’s just for you.”
It is just for him. Riku would rip anyone - omega, beta, alpha - to shreds, probably, if they even just so happened to perceive the fact his hyung has a knot. If they even looked at him funny, if they even asked him his name. His omega tells him so. And Riku can’t really think of anything else.
Hyung is still smiling up at him. Riku grins, teeth sharp.
“Mine,” he says.
He gets restless from being empty, and so he fumbles with Sion’s sweats - stupid waistband! - and his fingers pull uselessly at the fabric. Sion has to help him, getting Riku to budge just a little so he can free his cock. And once it’s in Riku’s sights, he feels himself salivating.
“Belongs to me,” he mumbles, grinding against it. He moans as he rocks his hips forward, sliding Sion’s cock against his clit, groaning when Sion’s fingers dig harder into his hips. “All mine, just me, no one else gets to have you besides me-”
“No one, baby,” Sion says. He’s soothing his thumbs into Riku’s hipbones and purring, staring up at him. “You love it? You own me?”
Riku grits his teeth and snaps his hips harder. He wants it inside but it also feels so good like this, getting hyung all wet as he slides down his slit and teases at him. There’s the barest bulge of a knot at the base of Sion’s cock and Riku wants that inside of him right now.
“I own you,” he growls. “There can’t- there won’t be anyone else.” He’s panting as Sion’s tip catches on his hole and he pathetically just keeps humping his alpha, willing him inside. “They can’t- no one gets to look at you. Only me, only me, only me-”
“Take hyung inside you, baby,” Sion groans. “I’m yours. My knot’s yours.”
Riku can’t help but gasp when Sion angles his hips just so and catches on his hole again, this time slowly pushing in.
“My hyung,” he breathes. “My hyung, only my hyung…”
Sion sinks inside him and it feels so fucking good, getting filled right up. Hyung is warm and big, so big that he feels it in his tummy once he’s bottomed out. Riku’s never ridden him in his heat before, still holding Sion down by the shoulders as his arms shake with the exertion of keeping himself held up, feeling suddenly overwhelmed. His hips and thighs quake as hyung sinks right into his sweet spot, keeping him filled in the most delicious way possible.
“Good?’ Sion asks and Riku is drooling. He normally doesn’t talk much during his heat, brain too fuzzy to think properly. So Riku grinds his hips down, moaning, eyelids fluttering closed.
“Mine,” he whines. “My hyungie, my knot, no one else…”
“Can’t even look at anyone else when you take me like this,” Sion groans as Riku rocks back and forth, back and forth… “Don’t want anyone except for you, baby, you’re perfect.”
Riku moans. It’s so good. His omega loves the feeling of hyung inside him, wants this forever and ever. He can barely hold himself up as he rocks down on his alpha’s beautiful fucking cock.
“I’m hyung’s,” he says, groaning. “Hyung’s all mine, feels good, I love it-”
Sion growls, fingers digging deeper into Riku’s skin.
“Wanna bounce on it, princess?” He asks. “Wanna show me how much I’m yours?”
Oh, god, fuck. Yes.
Riku’s arms tremble as he lifts his hips up and sinks back down, but he doesn’t fucking care because getting filled like this is better than anything else. Hyung’s so nice and big and lovely and Riku rocks up before he’s thrusting back down and he’s full. His body in heat loves it like this, loves it when he’s owned, and so he bounces in his hyung’s lap and pants and takes it.
“There you go,” Sion mutters. “Belongs to you, hm? Feels good inside?”
“Belongs to me,” Riku agrees, drooling. He slams his hips down onto hyung’s cock and whines when it reaches so deep, his stomach churns. “Love it,” he says. “Belongs to me, love it,” he says again.
His arms feel so weak and his thighs are quaking but that’s, like, the least of his worries because hyung pulses in him every time Riku clenches down on him and it feels so good that he probably wouldn’t care if he fucking died right now. Sion’s grip on him tightens and he slams his hips up, making sure Riku rides him just right - just as roughly as he needs - and Riku chokes on a moan.
“That’s-” Riku mewls. “Right there-”
“You’re so good,” Sion coos. Riku’s brain feels like it’s melting out of his ears as hyung fucks him again and again and again, making him take it. His omega quiets down from a chant of mine, mine, mine, to a mumble of more, more, more.
His grip on Sion is growing weaker and Sion’s grip on him is getting meaner. His elbows hurt and give in on themselves when Sion thrusts into him so hard that he sees stars, and so Riku falls flat onto Sion’s chest and can’t get back up. His alpha’s so deep inside him that Riku can’t do anything besides take it, drooling into his neck and moaning: more, please, hyung, need more.
Sion smells so good. Spiced with arousal and desire and pleasure all at once. Riku’s slick is everywhere, making their scents mix, making the both of them smell like each other. Riku can’t help but mouth at hyung’s scent gland, help but drag his teeth over it and bite at it, wanting them to be even closer, wanting them to smell like each other forever-
Sion yanks him back by the hair, startling a moan out of him. “What are you doing, baby, trying to bite me? Do I need to muzzle you?” His gaze has turned crueler as he forces Riku to look him in the eyes. Riku shakes his head, he wants- he just wants to be good.
“No,” he mewls. “I just- it’s so-”
He gasps when Sion slams into him even rougher, as Sion lets go of him and goes tumbling back down. He sobs into Sion’s collarbone and mouths at him, but doesn’t try to bite again. Hyung said he couldn’t, hyung said he couldn’t…
“That’s right, baby, you listen so well,” Sion spreads his thighs wider with large palms and spreads him so open. “You’re a good boy, aren’t you?”
Riku’s so wet that there’s slick everywhere, all over him. Sion spreads his cheeks and pets over his asshole, getting it wet, and he can’t help but cry again.
“I am,” he wails. “I’m good, I’m good, I’m-”
“Yeah, you are,” Sion growls. “You’re always good for me.”
Riku feels mindless. His omega can’t think about anything other than how badly he wants to be knotted. His cunt throbs as Sion bullies into him over and over again, sore but taking him so easily. His clit’s been overstimulated for days and he cries when Sion reaches between them to rub at it. Fuck. Fucking hell.
Sion’s knot has grown bigger, so much bigger. The threat of it batters against his pussy as Sion snaps his hips. Riku wants it in him so badly that he could die, especially when his alpha plays with his cunt and coos at him, making him feel so small and good and pliant. He’s going to be bred, going to be fucked full, going to have hyung’s pups like he’s always wanted. It makes him feel insane.
“Please, hyungie,” he cries. “Feels so good, love your knot, want your pups-”
“Fuck, you’re so cute,” Sion groans. “You love it, princess? Wanna be bred?”
“Yes,” Riku sobs into his neck. His hands clutch onto Sion’s shoulders, shaking, his whole body tense and aching to come and feeling so, so good. “I’ll be good, hyungie, please, I want you to breed me, please-!”
“There’s my polite boy,” Sion says in his ear. “You’re so sweet when you’re full of me, honey. ‘M gonna breed you so well.”
Riku wails when Sion spreads his thighs wider and fucks up into him so hard that he chokes. Doesn’t even know what to do as his body just takes it, as his omega whines for a knot and he begs please, please, want it, please. The heat’s made him so lost in his pleasure, hiccuping when Sion slams into him and keeps him spread open on his lap. Drooling when hyung bullies his clit.
“Knot, please,” he mewls. “Please, hyungie, want your pups.”
He wants it so fucking bad. Wants to be mated and filled and bred and given the life he’s always dreamed of, where his Sion hyung and his pack and his pups all live happily ever after and everything feels this good all the time.
“Wanna see you come first,” Sion says. “Then hyung will breed you.”
“But I wanna come with you-!” Riku whines. Sion’s grown against him, the bulge of his knot threatening. “Please, lemme come with you, want hyung to get me pregnant-”
“Fuck,” Sion growls. “Fucking hell, your mouth.”
Riku wants to say that’s not fair because hyung’s mouth is so much dirtier, but he can’t because Sion’s knot is slowly pulling him apart. Pressing in with each thrust, teasing him. Being spread open that wide feels good, feels amazing, feels like just what he needs.
“You want it?” Sion groans. “Want me to breed you with my pups, princess? Get you nice ‘n full?”
“Please,” Riku begs. “I want hyung’s pups, I wanna be your mate.”
That gets Sion to growl. His knot spreads him wider, threatening to pop. Riku’s pussy’s so sore but it feels so fucking good, feels perfect.
“It’ll take,” Sion promises. “It’ll take and we’ll have our pups, baby, keep you full for as long as you want-”
Riku moans into his neck. “Want you to fill me forever.”
Sion groans like he’s devastated and his knot pops right in, slotting inside him so roughly that Riku wails. He comes as he’s filled right up, sated immediately by getting bred just like he wanted. His hyung moans when Riku clenches down on him, milking him for all he’s worth, sticky fingers tugging at his clit until Riku squeals for him to stop. His hips and thighs tremble but it’s so good, and his alpha’s so deep inside him, and he’s getting properly bred full.
Sion is panting. He runs a shaky hand through Riku’s hair, another down his back.
“Was it good?” He asks. “You know I’m yours?”
Riku can’t even think properly, too far gone. But his lips quirk into a smile as he noses at Sion’s scent gland.
“Yes, hyung,” he murmurs. “You’re mine.”
-
After that, Riku’s heat passes by in a relatively normal manner.
He goes back to being manhandled and enjoying it, his omega so docile that it’s a little embarrassing. The possessiveness bleeds out of him and he doesn’t even care when the company-mandated heat caretaker, a beta, comes in to feed them and sees his hyung’s knot plugging him up. He doesn’t remember much about the first wave of his heat, but Sion tells him that he was incorrigible.
Huh. That’s a new word.
Once his heat’s over, he’s dragged to the doctor’s, wherein it is confirmed that he’s probably back to normal and their bond is steady again. They’re advised to not separate, not unless they mate, which is… you know. Not an option. But Sion seems a little pleased that Riku can’t get rid of him and Riku is similarly happy that his hyung is stuck with him either way, so there’s no complaints about that.
The group is unruly but settles down once Riku goes back to normal, meaning he is frequently jealous over petty things and definitely going overkill on the aegyo for his hyung, but otherwise not outwardly possessive in the least. He tracks down that rookie omega to apologize - who just bows and promises to never speak of it again - and gets Jisung’s number so they can actually be friends.
“I kind of miss when you were all over me,” Sion pouts in the nest after another fan meet where Riku only compliments him the usual amount (which is still a lot, many would say). “You’re so cute when you’re jealous.”
“I dunno what you’re talking about,” Riku says, ears red, burying into Sion’s side. “I thought I was already cute to you.”
That, at least, gets Sion to grin. He swoops down to kiss him right on the lips.
“Ah, yeah,” he says. “You are.”
It’s nice, living a little unconventionally, being almost-mated to his groupmate. It’s nice having his pups and his beta best friend and his favorite baby alpha to bother. It’s nice seeing his alpha on stage, squealed over by the masses, knowing that Sion hyung is all his. No one needs to know. It’s enough that they belong to each other.
(But, sometimes-)
“You’ll never believe what this noona said about Sion hyung’s chest!” Ryo bellows one morning, slamming the bedroom door open. “She said she wants to-”
“Absolutely not,” Riku, half-asleep, can’t help but growl. “He’s mine.”
