“It’s a bad idea,” Yeji says the instant Jeno lays out Chenle’s insane plan in front of her. “It’s a terrible idea. No.”
Jeno scowls at her. He made Yeji meet him at this café so that she could convince Jeno that everything would be fine, that Chenle asking Jeno to stay with Jaemin during his rut wasn’t totally bonkers. Not for her to shut him down. Certainly not for her to tell him no. He already agreed to do it, anyway. Now he’s more nervous than he was when he got here. He mourns the person he was five minutes ago, the Jeno who was cautiously optimistic. That Jeno is now buried somewhere in Yeji’s backyard.
“Jeno, really,” Yeji says, looking way too put together and sophisticated as she sips her iced coffee, a far cry from the disheveled mess that Jeno is after a three hour meeting and two bus rides across the city. “It would be one thing to have an omega with him. That makes sense. But you…”
“I know. Betas are useless during rut, you don’t have to remind me.” Jeno begins tearing a paper napkin into small strips, refusing to look at Yeji.
“I didn’t say that,” Yeji interjects, setting her glass down delicately. “I’m just saying that I don’t think you specifically being around Jaemin during his rut would end well for either of you. You two–”
“Us two nothing,” Jeno interrupts. “There’s nothing about me and Jaemin that could factor into this situation.” It’s definitely one of the stupider lies he’s told. Especially to Yeji, of all people. Yeji knew he liked Jaemin before Jeno himself even knew.
“Do you think I’m dumb?”
“No.”
“Okay, then stop lying to me. You like Jaemin and Jaemin likes you. I don’t think I should have to explain to you why the two of you, alone, unsupervised, during Jaemin’s rut, is not going to end well.”
Jeno makes a face at the confetti he’s made out of what was once a napkin, choosing to ignore 99% of what Yeji’s just said. “Chenle said…”
Yeji clears her throat. “Chenle said that Jaemin isn’t like other alphas.”
Jeno’s eyebrows shoot up before he can stop them. “Uh… yeah. How’d you know?”
Yeji shakes her head. “He said that because to him, Jaemin isn’t like other alphas. And I’m sure he believes that, but it’s not true.” Jeno opens his mouth– to protest, to question, he doesn’t know– but Yeji raises a hand before he can get any words out. “Listen. Rut is different for every alpha, but there are usually a few things that hold true for all of us. One, it’s not all about sex. I mean, yeah, it kind of is,” she adds at the dubious look on Jeno’s face, “But really, it’s about… feeling needed. Being protective, feeling like the people we care about need us to protect them. Mating is an easy way of doing that, and not only does it help us calm down, a lot, it also makes it obvious to everyone around us that our omega is spoken for. But obviously we can’t mate with every omega we see, nor do we want to. And like I said, it’s different for everyone. Jaemin is protective over Chenle already, so I can imagine that when he’s in rut he’s totally overbearing. He doesn’t have any sexual feelings toward Chenle, so what matters most to him is making Chenle feel safe, or at least, making himself feel like Chenle is safe. He wants to feel useful, he wants to feel like an omega that matters to him needs something from him. So he’s more controlled around Chenle, and of course Chenle thinks he’s not like other alphas, because Jaemin isn’t trying to sleep with him every waking second of his rut. You see?”
Jeno is still trying to make sense of it all, but he nods slowly. “So what you’re saying is…”
“What I’m saying is there’s a pretty high chance Jaemin is going to want you. It doesn’t matter that you’re a beta, he likes you a lot already, so in rut… he’s going to really want you.”
Jeno flushes, struggling to meet Yeji’s eye. “I don’t think that’s true,” he splutters, and Yeji rolls her eyes.
“You know it is,” Yeji insists, giving Jeno a glare that makes him want to run for the fences, and so he relents.
“I guess,” he says in a small voice. “So… what do I do?”
“You already told Chenle yes, didn’t you.” It’s not a question. Jeno gives her a sheepish look.
Yeji drums her fingers across the table. “Well, take care of him the best you can. He’s probably going to want as much skin contact as possible. I mean, he’s never been around anyone but Chenle during his rut, so… I don’t really know how he’ll act. He’ll probably be really overwhelmed, because he won’t have Chenle to be protective over, so my guess is… he’s gonna really want to fuck you. But he won’t, because he’s Jaemin, and he knows he’d break you.”
Yeji says it so casually that Jeno wants to die. It’s embarrassing, to have Yeji say shit so candidly like that, shit like “he’d break you,” because it’s another unwanted reminder that Jeno has essentially nothing to offer to Jaemin. He always feels so fucking useless as a beta, and he knows there’s nothing wrong with it, but still. There’s also the way his stomach lurches at the words, because he knows it’s true, and worst of all, he can’t help but think “I’d let him.”
“What?” Yeji is looking at Jeno like he’s fucking crazy, and Jeno realizes that he just said that last part out loud.
“Yeji–”
“Jeno, that’s a really bad idea.”
Jeno blushes and stares down at the table. “I know.” Yeji knows him better than anybody, so there’s no use pretending he didn’t mean it.
“Like, that’s a really fucking bad idea. And if you say that to him, he’ll…”
Jeno slumps down in his chair, as if doing so will make him disappear out of this café with Yeji. He wishes he was anywhere but here. Still, he can’t help but ask–
“Can betas mate with alphas? I mean, really, everyone says no, but…”
Yeji sighs, picking at her own napkin as if she’s debating answering the question. She must feel really bad for Jeno, because she does, despite her better judgment.
“If you mean actually mate, like, have kids, no. Obviously. But as far as, like, imprinting and shit… Technically, he could imprint on you. And it would work the same, I mean, we’d all be able to smell him on you, alphas would leave you alone, etcetera. And you can have sex, obviously you can, just… I would really, really not recommend you guys fuck during his rut. Be there for him, sure, help him as much as you can, sure, but if you let him knot you… Jeno, you will seriously hurt. There’s no way around that.”
“Not like it would even help if I did,” Jeno mumbles, sounding miserable, and Yeji realizes how torn up Jeno really is over the whole thing.
“Jeno,” she says sternly, and Jeno meets her eyes, because when Yeji talks like that, when Yeji uses her mom voice, he can’t look away. “Jeno, it can work. It has worked. It works all the time. My mom’s best friend is mated to a beta, and they’re happy, and they’re fine. You can be with Jaemin, you can be what he needs during his rut. But I need you to understand how dangerous it is for you to let him knot you.”
Jeno supposes he should drop it, but his good sense gave way a long time ago. Yeji has already helped herself to the deepest corners of his brain, so he figures he might as well ask what he really wants to know.
“How dangerous?” He hears the way Yeji grumbles under her breath, something about being too horny for his own good, but he pretends he doesn’t hear.
“You want me to be totally real with you? It won’t kill you. It won’t even put you in serious harm. But it will hurt really, really bad, and it will take a few days for you to recover. And I would assume over time it would get better, you would start to get used to it, but for a while, Jen, it’s gonna be really painful. But if you really want… you’d survive. It just won’t be enjoyable. I mean, in heat, or rut, or whatever, it’s not about enjoying it, it’s about… you know… like, primitive desires and shit. It’s not uncommon for an alpha’s rut to trigger their omega’s heat. It’s a symbiotic relationship. But for you… it’s just totally different, because you don’t need is the way that Jaemin needs it. Which is why I would really recommend you guys have sex, like, normally before you let him fuck you during his rut. Okay?”
“Okay,” Jeno says in a small voice.
“So does that mean…”
“Mean what?”
“Mean you’re going to tell him how you feel?”
Jeno cringes at just the thought. He knows, just like their whole friend group knows, that Jeno and Jaemin pining after each other has got to be the worst possible situation for either of them, because neither of them will ever admit it. Jeno has shared more than a few moments with Jaemin that bordered on romantic over the years, but he’s never had the guts to actually say anything to Jaemin about it, and Jaemin is… somehow even more in denial than he is. They’ve been in this awkward romantic purgatory for years, never naming what’s between them, but never quite giving up on it either.
“Maybe,” he lies.
“Whatever,” Yeji says. “Well, maybe this situation could work out after all. Maybe you two freaks will benefit from some excessive horniness.”
“It’s just one day,” Jeno protests, “It’s just one day. I’m staying with him Thursday to Monday, but Chenle is sure that Jaemin’s rut won’t start until Sunday evening, and he’ll be back Monday morning. So, really, it’s just a few hours.”
“Okay,” Yeji says, not sounding at all like she believes it.
⭑
It’s just one day are the four words that propel Jeno through Thursday evening and most of Friday. It’s just one day.
Except, it turns out it’s not just one day, because Jeno is awoken at three in the morning, Saturday morning, because he senses someone standing in his doorway.
Jeno scrambles to sit up and turn his lamp on, grabbing his glasses, and as soon as he’s conscious and realizing what he’s seeing, he knows it’s all wrong. As a beta, Jeno’s sense of scent is pretty much the bare minimum– what does he need it for?– but even he can smell the difference in Jaemin. But his sense of smell doesn’t matter at all, because after taking one look at Jaemin, Jeno knows he’s in trouble.
“Je...no,” Jaemin says weakly, and he stumbles his way inside, leaning heavily on the doorjamb before continuing on towards the bed. Jeno is up in a flash, grabbing Jaemin’s waist, holding him close to his body and guiding him to the bed. He’s definitely closer than he needs to be, but he tells himself it’s for Jaemin’s own sake. Even he knows how lame of an excuse that is.
Jeno pushes Jaemin onto the edge of the bed and then mimics his position, sitting next to him. He (accidentally?) sits way too close, and he feels electric shocks run up his spine when Jaemin’s elbow grazes his ribcage.
“Jaemin,” Jeno says, hyper-aware of the way that their thighs are pressing together. The younger gives zero acknowledgment that he even hears him. “Jaemin,” Jeno repeats, gentler, and Jaemin whines. Even though he already knows the answer, he asks, “What’s wrong?”
Finally, Jaemin looks at him, turning his face down to meet Jeno’s gaze. “Hot,” he whimpers.
Jeno knows. Jaemin is a small furnace, and the temperature in the room already feels like it’s increased a couple degrees. Still, he presses his hand to Jaemin’s forehead, and sure enough, Jaemin is absolutely burning up. The touch seems to have a slightly calming effect on Jaemin, who lets out a tiny sigh of relief. A bead of sweat trickles down the side of his face, and Jeno suddenly realizes that he’s warm, too. It’s making him lightheaded.
“Jaemin, let’s go to the bathroom,” he suggests gently, sweeping Jaemin’s sweaty bangs off his forehead.
“Why,” Jaemin moans, and then he keels over, burying his face in Jeno’s shoulder. Jeno freezes. His breath hitches, and then, after a moment, Jaemin starts nosing up his neck, clearly intent on scenting him. Which might help if Jeno was an omega, but he’s not, so he peels Jaemin off of him.
“Need to cool you down,” Jeno explains tersely, and Jaemin looks up long enough to give him a weak frown.
“Wanna stay here,” he insists, and he goes to scent Jeno again. This time, Jeno doesn’t stop him.
But maybe he should, he thinks, as soon as Jaemin pushes his hands up Jeno’s shirt, caressing Jeno’s sides with so much affection that Jeno thinks he might pass out.
“Scenting me isn’t gonna help you,” Jeno says flatly, trying to ignore the way the words make him feel. He hates that still, in all of this, he feels so fucking useless. He can’t bring himself to force Jaemin to remove his hands, so he doesn’t.
“It helps,” Jaemin insists, making an immense effort to raise his head enough to meet Jeno’s gaze. He sounds like he really means it. “You… your scent… helps. Makes me feel better.”
Jeno blushes. “Really?” he can’t help but ask, and in response, Jaemin just goes back to burying his face in Jeno’s neck, inhaling deeply. Jeno feels his heart start to race even faster than before. Sweat beads on his temples. It’s nice, for a moment, until Jeno realizes how achingly hot it’s become in the past few minutes.
“Jaemin, do you want to like… take a shower or something?” Getting Jaemin naked is the last thing Jeno wants to do (lies!), but it’s so hot that all he can think to do is make him take a cold shower. Jaemin’s hands have migrated to his chest, and Jeno closes his eyes, trying to breathe as Jaemin does some… things… that he definitely shouldn’t be doing. Jeno likes it anyway.
“No,” Jaemin says after a moment, his voice muffled. Jaemin plants a kiss right on the junction of Jeno’s neck and shoulder, and then Jeno can feel teeth – not biting, not yet. Just grazing gently across his shoulder. Jaemin squeezes his chest. Jeno feels faint.
“Okay,” Jeno says quietly. He’s not sure what an omega would be doing right now– well, he has an idea, which he will not be acting on– and he lets Jaemin do whatever he wants. He stares up at the ceiling, trying to steady his breathing, but there’s no use. He’s always wanted this. Maybe Jaemin has, too.
Jaemin lifts his head again, eyes lidded, and Jeno belatedly meets his gaze. Jaemin is looking at him almost in awe, and Jeno just can’t take it anymore.
It’s Jeno who kisses Jaemin, and Jaemin, bless his heart, seems a little surprised. He doesn’t reciprocate at first, and Jeno breaks away, second-guessing everything, biting his lip nervously.
“I’m sor–” he starts, but he can’t even get two words out before Jaemin kisses him back. He cups Jeno’s face in his hands and Jeno finds himself laying back, Jaemin crawling over him as his head hits the pillow.
Jaemin kisses him sweetly, but Jeno can tell he’s holding something back. He grips him by the back of the neck, tugging gently to separate them, and Jaemin blinks at him, his eyes refocusing on Jeno’s face with some effort. It’s taking a toll on him, Jeno realizes, to hold himself back. To be gentle. Jeno knows that all he wants is to fuck something (him specifically, he hopes), and Jeno knows that it’s making him burn up on the inside, but he’s still being careful.
But Jeno doesn’t want that. Jeno wants Jaemin, all of him, all of this; Jaemin needs him and he so desperately wants to be what he needs. Everything that he needs.
“You don’t have to be gentle,” Jeno says quietly, “It’s okay. I want you.” Jaemin is incredibly receptive to his touches, so Jeno flips them over carefully, nudging Jaemin into a sitting position up against the headboard and settling in his lap. Jaemin is already hard, he’s been hard, this whole time, they were both just pretending not to notice. Jaemin’s dick twitches when Jeno sits down on it. Jaemin’s pajama pants– which are patterned with fucking little pink bunnies– may as well not even be there, because Jeno can feel all of him. Jaemin’s chin is tucked into his chest, and he breathes heavily, seemingly lacking the strength to raise his head. Jeno strokes his hair and waits.
“Jeno, I– I can’t,” Jaemin groans eventually, long after their breathing has synced up. “You– Jeno, I’ll hurt you.”
“I’ll be okay,” Jeno replies, and he moves his hands to Jaemin’s face, cupping it gently. Jaemin’s gaze stays focused on his lap. “I want this. Do you?”
“Yes,” Jaemin insists, “But Jeno, you can’t– I just–”
“Jaemin,” Jeno says softly. He kisses Jaemin’s forehead and drags his lips down Jaemin’s face, over his nose, before licking Jaemin’s bottom lip. All that matters to him is touching Jaemin, feeling more of him. Tasting him. Jaemin’s pheromones are clouding his brain. Which they shouldn’t be able to do. Jaemin drags his eyes up Jeno’s body and glares at him as soon as he catches his eye, which makes Jeno feel– well.
“You can’t take it,” Jaemin says plainly, and he actually sounds fairly lucid. Jeno can tell by the way he’s gritting his teeth that it’s taking everything in him to clear his foggy head. The words make Jeno’s stomach feel hollow.
“Yes I can,” Jeno insists, but he knows Jaemin is right. Jaemin will tear him apart. He wishes he cared. Maybe he’s lost his mind.
“You know you can’t,” Jaemin mumbles, “Jeno, I’ll destroy you.”
“It’s okay,” Jeno whispers back, pressing his forehead against Jaemin’s. “I’m okay.” He’s definitely lost his mind.
“Jeno, I need you to listen to me,” Jaemin chokes out. “Listen.” Jeno pulls away enough to meet Jaemin’s eyes again. They’re glowing, and Jeno feels something uncoil deep in his gut. He wants Jaemin to do anything he wants to him. He really, truly, does not give a damn if it ruins him.
“I’m listening,” Jeno mumbles, pushing his hands up Jaemin’s shirt. Jaemin lets out a growl that he can’t stifle, and then he grabs Jeno’s wrists in one of his hands, yanking them back out. He fits his fingers around Jeno’s forearms so easily it makes his head spin. Yeah, Jaemin is definitely going to destroy him.
“It’s going to hurt,” Jaemin says. “It’s going to hurt, and you’re going to cry. You aren’t made for this. You’re not made to take an alpha’s cock. You know this.”
“You can do whatever you want to me,” Jeno says desperately, pathetically, Jaemin’s words going in one ear and out the other. He can feel Jaemin’s hardness beneath him and he just wants the alpha to be inside him. He wants Jaemin to tear him apart. “I want you. I need you, Jaemin.”
“Jeno,” Jaemin growls, and this time, it sounds like a threat. Jeno blinks at him. Jaemin grabs him by the hair and forces Jeno to look him in the eye. Jeno wasn’t listening before, not really, but now he is. He leans into the grip Jaemin has on his hair like a psychopath.
“Jeno, your body is not made for this. You are not made to be bred. Your little body is not meant to take my cock, or my knot. You aren’t supposed to take my load. I am going to tear you apart from the inside out. You are going to hurt, and you are going to cry. I can’t promise to be gentle. I’ll try, for you, but it won’t matter, because Jeno, you are not made for this.”
It makes Jeno cry. His head is spinning and all that matters is Jaemin. He just wants Jaemin, needs him to be inside him, needs him to fuck him. He shouldn’t be reacting this way– Jaemin shouldn’t be able to affect him this much. No alpha should. “I don’t care,” he sobs, “Jaemin, I don’t care. Please, Jaemin, I want you. I need you. I don’t care. Please fuck me, please.”
“Fine,” Jaemin snarls. “But I warned you, and you asked for it.”
Jeno chokes out another whisper of a “please,” pushing his index fingers under his glasses to dab at his tears. When he pulls them away, there’s black smeared on the pads of his fingers, and he realizes he forgot to take his mascara off before he went to bed. Oh, well.
Jaemin throws all caution to the wind. He knows he needs an omega, he needs someone who is designed to take all of him the way Jeno wants, but he wants Jeno. He would take Jeno over any omega in the world. And he feels bad, he does, he worries about hurting him, but Jeno has insisted over and over again that he doesn’t care. And neither does Jaemin. And at this point, he’s pretty sure he’s going to die if he doesn’t get to be inside him. Being this close to Jeno and not being connected is making him burn up.
Jeno reaches down, hasty, impatient, trying to get his sleep shorts off, but he’s so worked up that Jaemin has to nudge his hands out of the way and do it himself. Jeno lifts himself up, onto his knees, so that Jaemin can tug them down his thighs and then, with a small cry, he leans into Jaemin, burying his face in his neck as he kicks his shorts and underwear off, letting them end up on some unknown part of the floor. With Jeno still clinging to him, Jaemin reaches between Jeno’s legs to take off his own pants, using one large hand to hold Jeno against his chest and the other to remove his pants.
Even having felt it, Jeno flushes deeply when he sees the size of him. The room feels impossibly warmer, or maybe it’s just his core overheating. Before he even knows what he’s doing, he reaches between them, wrapping his fingers around Jaemin’s cock and squeezing. He can barely fit his hand around him. The thought of it going inside him is almost too much to process. Jaemin growls, thrusting up into Jeno’s hand. He’s leaking, a lot, and Jeno uses his precum to ease the slide.
“Will it fit?” Jeno whispers, knowing the answer doesn’t matter. Jaemin will make it fit. Jaemin’s dick stiffens even more at the words. Jeno squeezes the head, runs his thumb over the slit.
“It will fit,” Jaemin growls. Jeno feels himself leaking, too.
“What do I do?” Jeno asks, reluctantly removing his hand, the low groan Jaemin makes when he does so reverberating up his spine. He keens when Jaemin slides a hand up between his thighs, grabbing his ass, kneading his fingers into it.
“Lube,” Jaemin manages to get out, “We need lube.” He fumbles with his free hand, sticking it under his pillow, and he manages to extract a bottle that’s there from the last time he was jacking himself off to the thought of Jeno straddling him just like this. He drops it somewhere next to him, forgetting about it when he lays eyes on Jeno again.
Jeno is a trembling mess above him– they haven’t even done anything yet, and Jeno is shaking, which makes the alpha in Jaemin proud– which isn’t going to work, so Jaemin carefully flips them back over. Jeno stares up at him with wide eyes, and then he pulls his t-shirt off, baring himself completely to Jaemin. His glasses are crooked. The alpha bites back a growl.
“So pretty,” Jaemin mumbles, mainly to himself, but the words make Jeno blush. Jeno is pretty, in that way of his. Jaemin has always thought he was the prettiest, maybe in the world. Maybe ever.
“Can-you-take-your-shirt-off,” Jeno gasps out, stringing his words together and tugging on the hem of said shirt. Jaemin takes it off, enjoying the small squeak that Jeno makes once they’re both fully naked.
Jaemin could stare at Jeno for hours, especially if he looked like this, flushed and trembling in anticipation, but right now he has more pressing matters to attend to. His biological desire to put his dick in him, for one. He pushes on Jeno’s shins, and Jeno bends his knees, spreading them and making room for Jaemin to kneel in front of him.
For a few hazy moments neither of them really pay attention; Jaemin follows his instincts as Jeno’s thoughts run in circles. If he didn’t know any better, he’d think it was Jaemin’s pheromones taking over him, but he knows that’s not possible. At least, it shouldn’t be. Pheromone-drunk or not, Jeno is already dangerously close to falling apart.
Jeno pulls one of Jaemin’s hands to his mouth, putting two of his fingers in his mouth. He sucks on them for a second and Jaemin takes them out promptly, swearing under his breath. “Too much,” he mumbles. Jeno looks up through his lashes at him.
“What?” He’s having a hard time breathing.
“It’s too much,” Jaemin repeats huskily.
Jeno looks confused. “No, Jaemin, it’s okay, I–”
“It’s too much for me,” Jaemin explains, his voice impossibly deeper, and Jeno visibly swallows.
“Oh,” he says softly, but the damage has already been done. There’s an image burned into Jaemin’s mind, and he blinks hard, trying to get it to go away, but it stays: The picture of Jeno with his lips stretched around Jaemin’s cock, teary-eyed, clawing at Jaemin’s thighs. Jaemin doesn’t think Jeno could take all of him in his mouth, but he knows he would try.
“Jaeminnie,” Jeno says, pulling him back to reality. Jaemin shakes his head as if that will clear his lust-addled brain. “You can fuck my face next time,” Jeno whispers, and Jaemin doesn’t know how he knows but he doesn’t care. He’ll settle for next time. He leans in to kiss Jeno again, aggressive, messy. He bites a little too hard on Jeno’s lip and Jeno gasps, bucking his hips up, trying desperately to grind against Jaemin. Jaemin places one large hand in the middle of Jeno’s torso and pushes him back down easily, pulling away. Jeno’s glasses are fogged up when they break apart.
“Need you,” Jaemin rasps, reminding the both of them. Jeno fumbles blindly for the lube, squirting some into his palm and then taking Jaemin’s hand again, smearing the lube sloppily over the fingers that were just inside his mouth. Jaemin lowers himself onto his elbows between Jeno’s bent legs. Without hesitation, he takes Jeno’s cock in his mouth. Jeno gasps, arching his back in surprise, and once again, one of Jaemin’s hands pushes him back down, holding him in place like it requires hardly any effort at all. The fingers on Jaemin’s other hand are slick, prodding at Jeno’s hole, circling his entrance. Jaemin pushes the tip of one finger inside, testing, and when Jeno moans out “Please,” he forgets about taking it slow and pushes both of his fingers in at once.
Just two of Jaemin’s fingers are enough to send Jeno into orbit, and he moans, fucking himself onto the alpha’s fingers, grinding down desperately. Jaemin releases Jeno’s cock from his mouth and scissors his fingers a few times before adding a third finger, intent on stretching Jeno as much as he can. If this were any other day, he’d take his time, open Jeno up slowly, maybe make him cum once on his fingers before taking him, but this is not any other day and he is rapidly losing his sense of self the longer he denies himself the relief of being inside Jeno. Jeno is taking his fingers well, grasping at Jaemin’s hair, pulling his body closer while Jaemin works his fingers inside him. Jeno would rather die than tell him this, but Jaemin’s three fingers alone are bigger than the dildo he fucks himself with. The stretch burns, but he loves it. He loves this. He straightens his legs back out, too weak to even keep them up.
“I’m sorry,” Jaemin groans, and he collapses on top of Jeno, burying his face in his chest, pulling his fingers out. Jeno whimpers. “I can’t,” Jaemin continues, and Jeno understands. Jaemin’s cock is pressed against his thigh (Jeno is so glad he can’t see it, because he thinks the ratio of the size of Jaemin’s dick to the radius of his thigh would probably kill him), and Jaemin ruts against him uncontrollably.
“It’s okay,” Jeno whispers, “Jaeminnie, you can fuck me. I’m ready.” With great effort, Jaemin pulls away from him, sliding his hands between Jeno’s legs and the sheets, lifting his thighs back up.
“Lube,” Jaemin exhales, and Jeno hands it to him. Jaemin spreads Jeno’s ass open with one hand, and, without warning, pushes the entire nozzle of the bottle inside of Jeno. He squeezes in what he thinks is a good amount of lube, which ends up being about half the bottle. Jeno doesn’t like the sensation, plus it makes him feel pathetic, and he whines, but when Jaemin squeezes his side he shuts up.
Jaemin sits back on his knees, grabbing his dick and pushing the tip against Jeno’s hole. He presses the head inside, and Jeno gasps.
“Jeno,” Jaemin says, desperate, pleading. He’s shaking so hard he’s practically vibrating and Jeno knows the restraint is killing him.
“It’s okay,” Jeno breathes out. “You can… you can do it.” He knows there’s no going back from this. Jaemin glances at his face, his expression dark. Jeno nods jerkily, and they both turn their gaze back to the spot where they’re joined together.
Jaemin pushes all the way inside slowly, each inch making Jeno’s chest tighter, every centimeter loosening some of the tension inside Jaemin. The sensation is something like lighting up Jeno’s spine.
“You take me so well,” Jaemin groans, his fingers digging into Jeno’s legs where he holds him, hands tucked under Jeno’s knees.
Jeno tries to speak, but he can’t. He’s had the breath knocked out of him, no, forced out of him, he’s full to the absolute brim. He can’t fucking breathe, and he reaches wildly for Jaemin as he tries to adjust– as if that’s even possible. There’s no way he can adjust to Jaemin’s size, Jaemin was right, he’s not made for this, but he still tries to gather his wits as he feels himself being absolutely split open.
Jaemin realizes he isn’t breathing, and he tries to get him to start, murmuring, “Breathe, breathe,” but he quickly grasps that isn’t going to get the job done. Jeno’s face is turning paler by the second, and he panics, he goes to pull out of him but he can’t, it’s like his body won’t let him, so he does the only thing he can think of and slaps Jeno.
It works. Jeno gasps in a sharp intake of air, and then coughs it out, and then inhales again, and Jaemin lets out a breath of his own once Jeno starts breathing again, albeit shallowly and irregularly.
“Too big,” Jeno manages to get out. Jaemin has the sense to look ashamed.
“Do you want me to–”
“It’s fine. I’m fine. Just… wait.”
Jaemin waits. The urge to not wait, to just fuck him, tears through his body, but he waits. If he hurts Jeno any more than he has to, he won’t be able to live with himself.
“I can’t– I’m sorry,” Jeno gasps out. “I’m okay.” He’s not okay. He’s so full, and he allows himself one spare glance at Jaemin’s cock through his normally flat stomach before he averts his eyes. He can already feel the way Jaemin’s cock distends his stomach. Seeing it is too much.
Jaemin’s hands are shaking as he uses them to brush Jeno’s hair back– not shaky from nerves, but shaky from the way it’s taking everything in him to restrain himself from pounding into Jeno like there’s no tomorrow. He jostles a little, accidentally, and Jeno can practically feel it behind his sternum.
“God,” Jeno forces out, his entire body strained, the intrusion making him tense everywhere.
“Are you okay?”
Jeno hesitates, then nods. Though he’s not ready for Jaemin to actually fuck him, he doesn’t think he ever will be. “You can move.”
Jaemin doesn’t ask again. As soon as Jeno gives him permission, Jaemin drags his cock almost all the way out, pausing for barely a second before slamming back inside him. Jeno gasps; he’s still struggling to breathe because his chest is so tight and he looks down, again, despite his better judgement, only to see the tip of Jaemin’s cock, pressing from the inside out, between his ribs.
Jeno’s mascara is running in tiny rivulets that trickle from the corners of his eyes, trailing out from behind his glasses and down the sides of his face, toward his ears. Entranced, Jaemin stops moving for a second, holding himself over Jeno with one arm and using the other to wipe some of it off, but he only succeeds in smearing it more. He grinds his hips against Jeno’s ass and Jeno whines.
“Am I better?” Jeno asks with a gasp, desperate, delusional. “Am I tighter than the others?”
Jaemin just growls, wrapping his hands around Jeno’s sides, holding him in place as he fucks him.
“Tell me I’m the best,” Jeno demands, writhing underneath him, unable to squirm out of Jaemin’s grasp, but he likes it. Jaemin being able to hold him down and do whatever he wants with his body is so… hot.
“You’re the best,” Jaemin chokes out. “The tightest I’ve ever had.”
Jeno just smiles in response, his eyes rolling back. He can’t talk, not anymore. Not with Jaemin plowing into him the way he is. Jaemin drives into him harder, and Jeno moans louder. The pain edges into pleasure, but the lines are blurry and he can hardly make out what hurts and what feels good.
“So wet,” Jaemin groans under his breath, and even though it’s purely the lube that makes it so, Jeno has produced zero of the slick inside him himself, the elder still turns bright red. What’s worse is that Jaemin is right– he is wet, wetter than any omega could get naturally, probably, wetter than any omega Jaemin has ever had, and Jeno covers his face with his hands. Jaemin pulls his hands away, forcing Jeno to look at him. “So wet for me. All for me. No one else makes you this wet, huh?”
Jeno whimpers, chewing on his lip, wishing he had his hands or a pillow to hide behind but all he has is Jaemin’s eyes boring into his skull, commanding a response.
“N-no,” Jeno whispers, “N-no one else. I o-only get this wet for you, Jaeminnie.”
Jaemin smirks, a sick, demented smile that slashes across his face and makes Jeno stare at him, open-mouthed. He doesn’t talk anymore, moving one hand to Jeno’s thigh, spreading him open even more. Jeno feels Jaemin burning the shapes of his fingers into his hip and the soft part of his thigh and shudders. He cums before he realizes what’s happening, barely registering when he spills all over himself.
“Is it that good?” Jaemin teases, and Jeno nods weakly. Jaemin drags a finger across Jeno’s stomach and brings it to his mouth, lapping Jeno’s release off his finger. It’s too much. Jeno spasms around him.
“Jaemin,” Jeno whispers, screwing his eyes shut. Jaemin leans over him, grabbing one of his hands, intertwining their fingers. With the other, he holds himself up on the headboard, his strokes becoming slightly slower, more deliberate as he grinds into him harder.
“Just a little longer,” Jaemin murmurs in his ear, squeezing Jeno’s hand. Jeno wraps his free hand around Jaemin’s neck, his head lolling to the side. “You’re doing so good, taking me so well. You feel so good, Jen. No one is as good as you, baby.” The praise makes Jeno smile weakly.
“Are you gonna do it soon?” Jeno asks.
“Yeah, baby,” Jaemin groans. “Gonna give you my knot, just like you wanted.”
Jeno moans, jerking a little from all the stimulation. A few more drops of cum slide down his cock.
Jeno knows it’s going to happen before Jaemin says anything, he can tell by the way Jaemin loses his rhythm and moans that he’s close. Jeno gives him a small nod, squeezing the back of his neck. When Jaemin looks down at him, his eyes are black.
“Here,” Jaemin growls, and Jeno loses his mind.
Jeno squeezes his eyes shut when he does it, and he can hear Jaemin let out an animal growl and go lax, like all of the tension in his body is gone. Jeno wishes he could say the same. He thinks that he screams, but he doesn’t feel like he’s inside his body anymore and he can’t tell.
“You’re mine,” Jaemin says, his voice low, lapping at Jeno’s skin, licking the sweat off the side of his neck.
Jeno can only see stars.

It’s some time in the afternoon when Jeno wakes up, and he realizes within seconds that he can’t fucking move. Every part of him hurts, from his toes to his scalp, and he tries desperately to focus on his breathing. Even that hurts, burns, and he squeezes his eyes shut, clenching his fists, as if digging his nails into his palms will help bring him back from the brink of passing out. It works, kind of, and when he opens his eyes again, Jaemin is hovering over him. He has no idea when he got there.
“Jeno?” he asks, sounding terrified, and Jeno gives him a curt nod to let him know that he at least heard him. “Jen, are you okay?” He sounds so worried as Jeno shakes his head, but that movement hurts, too, and he squeezes his eyes shut again.
“It hurts,” Jeno croaks out.
“I’m sorry,” Jaemin whispers, “I’m so sorry. I shouldn’t have– oh my god, Jeno, I’m sorry. I’m sorry. I never should have, fuck, Jeno, I–”
Jeno manages to gather all of the strength in his body to move his arm a fraction of an inch and wrap his fingers around Jaemin’s pinky, which shuts him right up.
“It’s okay,” Jeno groans, “‘Please–” His words die in his throat, and he has to concentrate to get them to come out again. “Hold me,” he asks, demands, and then he gives up on talking.
Jaemin seems terrified to even touch him, but Jeno is now staring at the ceiling, eyes unfocused, and Jaemin knows that he won’t be getting any more words out of Jeno for the time being. As carefully as he can, he peels the covers back and climbs into bed with Jeno, turning him on his side and pulling him close, pressing his stomach against Jeno’s back. He feels Jeno relax minutely as he lets out a small breath, and Jaemin feels a little better.
“Are you hungry?” Jaemin asks after a while. His anxiety is radiating off of him, ramping Jeno up, and it’s not great for either of them.
“I don’t know,” Jeno groans, “Everything hurts.” And then he adds: “Stop vibrating.”
“Sorry,” Jaemin mumbles. He goes still next to Jeno. “I’ll get you something to eat,” he adds after a beat, slinking out of bed, tucking Jeno in after he leaves.
“Nothing solid,” Jeno calls after him, his voice hoarse.
In the silence, Jeno tries to think. He’s trying to remember everything that Yeji told him, about how this could work.
“Here,” Jaemin says, rematerializing at his side. He gently slides his arms under Jeno’s armpits and pulls him into a sitting position, propped up against the bedframe. He grabs Jeno’s glasses from the bedside table, where he must have put them last night, and puts them on him before pushing a mug of soup into Jeno’s hands. Jeno accepts it gratefully.
“Thank you.” Jeno barely gets these words out before Jaemin is talking over him, tripping over his words in a hasty attempt to get them all out at once.
“We need to talk,” Jaemin rushes out, and Jeno just raises his eyebrows at him over his soup.
“Okay.”
“I— Um.” The words are harder for Jaemin to get out than he thought they’d be. There’s really no way around it, so Jaemin finally says, “I… marked… you.”
“I know.”
Jaemin straightens in surprise. “No, I mean—”
“You imprinted on me. I know.” He remembers it. He remembers the knot, the pain, the hot pleasure at knowing that they were bound together and no one could separate them. He remembers opening his eyes to stare at Jaemin, the tears in his eyes making him blurry.
“You’re mine,” Jaemin had said.
“Make me yours,” Jeno had whispered, and Jaemin had wasted not a second before biting down, hard, solid, on his collar bone.
“Look at it,” Jeno orders Jaemin in the present, and Jaemin, still apparently shocked, obeys robotically, gently pulls the collar of Jeno’s shirt down. “What does it look like?” The mark is deep purple, and Jaemin can make out each individual tooth mark.
“It looks… Like I claimed you, Jeno,” Jaemin responds, sounding a mixture of proud and ashamed.
“Good,” Jeno says, but Jaemin is already talking, missing what he says completely.
“I didn’t ask,” Jaemin says guiltily, looking genuinely miserable. “I’m sorry, Jeno.”
Jeno drinks some of his soup and then hands it back to Jaemin, who puts it on the table. “Jaemin, I told you to.”
Jaemin flushes. “I know, but Jeno, you… You weren’t in your right mind.”
“I’m a beta,” Jeno reminds him, and for once the words don’t make him feel ashamed. “Your pheromones can’t affect me.” Even as he says it, he knows it’s a lie. Maybe biologically Jaemin’s pheromones shouldn’t affect him, but…
Jaemin looks at him dubiously, and Jeno bites his lip to stop himself from giggling.
“Okay,” Jeno says, wishing very much to skip right over the discussion of whatever the fuck happened to his brain last night, “You’re right. But Jaemin, I promise you, there is nothing more in the world that I wanted. I swear. I’ve always wanted you. Ever since I met you. Even before I knew you were an alpha. Even before I found out I was a beta and was scared it could never work.”
Jaemin takes Jeno’s face in his hands, leaning in close, searching his face for something. Jeno doesn’t know what.
“Do you mean that?” Jaemin demands, his eyes wide, and Jeno is surprised.
“Jaemin, haven’t you always known?”
Jaemin shakes his head furiously. “Jeno… I never knew… I…”
Jeno covers Jaemin’s hands with his own. “Jaemin,” he says gently, “Ever since I have known you, this is all I’ve ever wanted: You.”
Jaemin kisses him, aggressive but tender, and Jeno kisses him back until it’s too much for his swollen lips.
“I’ve always wanted you too, Jeno,” Jaemin says gleefully, “And now you’re mine.”
“Really?” Jeno asks.
“Of course,” Jaemin replies, smiling ear to ear. He gathers Jeno into his arms and lifts him onto the other side of the bed before climbing in next to him.
Jeno pushes his face into Jaemin’s shoulder. “Good,” he whispers.

When Jaemin gets up to go to the bathroom, Jeno pulls the collar of his shirt down. As quickly as he can, he takes a picture and texts it to Yeji.
nice, Yeji responds.
That’s all you have to say???
She sends back a picture of herself flipping him off. U didn’t listen to me, asshole, she responds.
Jeno sends a frowny face.
Just kidding!!!! Happy for you >:)
Jeno sends a heart.
Yeji replies, slut.
