Work Text:
“Hyung?” He hears Jungkook’s voice from the bathroom, and he knows that he can probably smell his rut from a mile away now he’s awake. “Are you-?”
“Yeah,” Jimin croaks out, running a hand through his hair. “Yeah, it’s here.”
His rut’s been due for almost a week now, and this morning it’s finally making an appearance, waking him up with a headache, a body temperature about 20 degrees above normal, and an aching hard-on. It’s a relief when Jungkook appears shirtless in the doorway, freshly showered and dried, wearing only a pair of plaid pyjama bottoms. That’s a view that would turn Jimin on any day, but right now it’s like he’s been doused in scalding hot water, his whole body aching just at the sight and smell of his boyfriend even from across the room.
“Jesus, Guk,” he says weakly. “Get over here.”
Jungkook grins and comes over to climb onto the bed, letting Jimin pin him to the sheets and press a heated kiss to his lips.
“Mm, good morning,” he says breathily as Jimin gently scents him along his jawline. “You smell so nice.”
Jimin smiles at him. “Good,” he replies, voice a little rough. “It’s all you’re going to smell like for the next three days.”
He grinds their crotches together, eliciting a quiet moan from Jungkook. Jimin’s pulse is racing about a mile a minute, his inner alpha unable to concentrate on anything except the thought of getting his knot inside his omega boyfriend.
“Kiss me again,” Jungkook demands.
“No,” Jimin says shortly. Usually he’d draw this out a little more, especially since it’s still early in the morning, but his rut is making him frenzied and he doesn’t have the patience. “Take these off,” he tells Jungkook brusquely, tugging at his pyjama bottoms.
Jungkook hesitates for a second and then gives him a small smile. “No.”
Jimin scowls. “No?”
“I’m not taking them off until you give me a reason to,” Jungkook says sharply. “‘Til you get me wet enough.”
Really? Jimin thinks. Today's the day you choose to be a brat?
He considers doing it himself, but he huffs and straightens up instead, staring down at Jungkook with narrowed eyes. “Fine,” he says tersely, and pulls back, pulling off his t-shirt and then his boxers.
Jimin can see Jungkook falter for a moment when Jimin fists his hard cock. His hyung is hung even on an ordinary day, thick and long enough to leave him limping, but his rut means it’s even more massive than usual, at least 12 inches and as thick as his forearm. Jimin smells the sweet slick that leaks from Jungkook at the sight of it, and he smirks.
“You still feeling bratty, baby?” he goads. He leans in close to Jungkook, who looks a little betrayed with himself, and then suddenly pulls at his legs, yanking him towards him. Jungkook gasps.
“Gonna fuck you until you can’t even speak, baby,” Jimin hisses into his ear, letting his alpha take over. Jungkook swallows. Jimin’s scent is strong and cloying, so close to his face. “Gonna breed you until you forget your own name, forget everything except for how my cock feels inside you.”
For a moment, Jungkook looks like the air has been punched out of his lungs, and Jimin’s alpha preens, thinking he’s won this strange little power struggle. Jungkook lets Jimin take off his pyjama bottoms, leaving both naked on the bed - but when Jimin goes to spread his legs, he suddenly sits up, clenching his thighs together and refusing to budge.
“You’re going to have to try harder than that, alpha,” Jungkook sneers.
Jimin freezes. “What the fuck?” he spits, genuinely irritated. “Cut it out. I need to fuck you.”
“Aren’t you gonna make me?” he mocks. “Except you can’t, hyung. All those mean alpha rut pheromones and you still can’t pin me down.”
This kind of talk isn’t rare from Jungkook, who is remarkably obstinate for an omega and likes to make Jimin work for it, occasionally even taking on the dominant role in the bedroom when he feels like it. However, he’s never pulled a stunt like this during one of Jimin’s ruts, and Jimin feels himself getting impatient as his alpha gets more desperate. He tries to grab at Jungkook again, but he wriggles away.
“God - stay still, you dumb fucking omega,” he snaps.
Jungkook blinks at him. Jimin is shocked at himself. He’s never spoken to Jungkook like that before. He’s about to apologise, but then he notices that Jungkook is grinning, and his scent hasn’t been dampened at all. If anything, he seems to have incited Jungkook further.
“Are you embarrassed because your omega is so much bigger and stronger than you?” Jungkook taunts, leaning back on his tattooed arms as if to flaunt his muscular figure. “Because you can’t throw me around, make me do what you want?”
Admittedly, it is unusual for an omega to be taller and broader than their alpha, albeit only by a couple of inches. They’ve gotten some strange looks from acquaintances, people who can’t hide their surprise when they finally clock that Jimin is the alpha, not his built, heavily tattooed boyfriend. Most of the time it doesn’t bother Jimin at all - he’s confident in himself, and he understands the confusion, finds it funny, even. But right now he’s deep in an alpha headspace, and Jungkook is challenging his dominance. He grits his teeth.
“You know I could make you do anything I wanted you to,” Jimin growls, gripping Jungkook’s thighs hard enough to bruise, but not forcing them apart, no matter how much his alpha screams at him to. “Stop testing me, Guk.”
Jimin can smell more slick leaking from Jungkook at his words, the scent driving him even crazier. But Jungkook still doesn’t let up. Instead he uses his full strength to pull himself backwards, out of Jimin’s grasp so he’s lying back on the pillows.
“You can’t make me do anything, dumb alpha,” he spits.
Jimin glares at him, jaw clenched. He’s reaching his limit. He’s knows he’s not going to hurt Jungkook, would never hurt him. But he’s not is the right state of mind for this game that he’s playing - he’s more alpha than person right now, and his alpha sure isn’t willing to entertain this, growling at him to make him submit. He feels the tension building in his body, riling him up.
“Jungkook,” he warns, his voice low. He moves closer, and Jungkook doesn’t move away this time. He can smell the excitement on Jungkook’s scent, how much he’s enjoying this - provoking him. His nostrils flare, lip curling back.
“What, you can’t even get me to open my legs?” Jungkook’s eyes are glinting tauntingly, and Jimin can tell that even he knows he’s pushing it now. “Can’t even make me stay down? What kind of an alpha are you? Aren’t you going to -”
That’s it. Jimin can’t take it anymore. Snarling, he throws his hand around Jungkook’s throat, just under his jawline, and yanks his head back into the pillow, giving him access to his neck. Then he presses a bruising kiss directly onto Jungkook’s unmarked mating gland, so hard that he can feel his pulse throbbing under his lips, sucking on it and scraping with his teeth like he’s about to bite him, claim him.
The reaction is instantaneous. Jungkook seizes up, his voice choking off into a sharp gasp. Jimin feels his omega’s body start to twitch uncontrollably under his hands, letting out broken whimpers and whines as Jimin aggressively marks him and scents him, before he suddenly goes pliant, hands dropping weakly from Jimin’s hair to the mattress. A rush of Jungkook’s slick, overpoweringly sweet, hits Jimin’s nostrils, and he growls into Jungkook’s neck, his body somehow growing even warmer as he feels his omega submit.
Jungkook makes a small, desperate sound in response. Jimin grabs his chin and pulls his face back towards him to stare him down.
Every trace of his defiant, bratty baby has disappeared in seconds. Jungkook looks like a picture of submission, eyes wide and slightly glazed over, mouth hanging open. Jimin’s alpha feels euphoric, his scent pulsing with dominant pheromones as it floods through Jungkook.
“You think I don’t know how to shut you up?” he hisses, staring daggers into Jungkook’s dilated doe eyes, his own pupils so constricted that they’re barely pinpricks. Jungkook’s breath hitches. “I’m your fucking alpha. You’re mine, you hear me? You do as I fucking say.”
Jungkook nods slowly, mindlessly, and cranes his neck back, presenting his throat in a show of submission. “Y-yeah,” he whispers breathily, his now-cerulean eyes fixated on Jimin’s glowing amber stare. “Yeah. I’m yours, alpha. I’m your omega.”
Jimin’s heart soars. He thrusts his hand under Jungkook’s thigh and pulls it up to his hip. Jungkook has stopped putting up any resistance at all, forced limp like a doll, letting his alpha move him however he wants. Jimin’s other hand trails down to Jungkook’s hole. He had been wet before, getting off on the power game between him and Jimin, but now he’s gushing slick, soaking the sheets under him, thighs glistening. Jimin feels his mouth water.
He coats his fingers in some of the slick flooding out of Jungkook, and presses two inside him quickly, leaning down to kiss at Jungkook’s neck again at the same time. Jungkook lets out a high-pitched keen, fisting the sheets desperately.
“Alpha,” he whimpers.
“So good for me,” Jimin murmurs into his neck, praising his omega without even thinking about it. Jungkook’s scent grows even stronger, delighted by the praise. Jimin gathers up more slick and presses in another finger alongside the others, Jungkook’s pliant body making it easy to stretch him out.
In his usual state of mind, unclouded by rut, Jimin would relish the opportunity to drag this out, to tease Jungkook until he was sobbing. He loves when his baby is this desperate for cock, usually a state only drawn out of him after hours of foreplay and edging, and any other time he would be savouring it. But right now Jimin can’t think about anything other than fucking his omega, than holding him down and breeding him over and over and over until he’s stuffed full of his cum.
Both of them have lost all sensibilities, dropped their acts, deep in their most primal states of being. Jungkook starts to squirm a little under his hands, getting impatient with the prep.
“P-please - please alpha, please fuck me,” he gasps out, voice needy, eyes flashing blue.
It’s a testament to the strength of their relationship that Jungkook even has the autonomy to ask Jimin for anything at all, his omega now so docile that it’s probably pleading with him to just lie still and take whatever his alpha decides to give him, no matter how bad he wants to get fucked. But Jungkook isn’t just any omega, and instead of feeling irritated, Jimin’s alpha screams at him to give him what he wants, to fuck his baby right now.
Jimin pulls out his fingers and positions himself between Jungkook’s thighs, pulling his hips up to meet his pelvis. He can feel Jungkook shaking like crazy under him, his face flushed and needy, whining gently under his breath. Looking at him, so fucked out and wrecked already, Jimin feels a sudden rush of love and affection so strong it made his head spin, and he knows it’s more than just his hormones. Jungkook must sense it too, because he whimpers slightly, staring into Jimin’s eyes with an expression so open and trusting it makes him shudder. Gritting his teeth, he lines his throbbing cock up with Jungkook’s hole and pushes in, bottoming out all at once.
Jungkook lets out a choked yell, hands flying to his own thighs to grip his flesh. Stars flash before Jimin’s eyes, and he leans down onto his forearms, bending Jungkook in half, who can only moan desperately. Everything else ceases to exist, and finally he gives in completely to his instincts – doesn’t take a breath, doesn’t stop to check in on Jungkook, just starts thrusting powerfully into the tight wet heat, hard enough that the bed frame slams over and over again against the wall behind them.
Jungkook screams then, voice cracking, his hands coming up to dig crescent moons into Jimin’s back as he takes his alpha’s cock impossibly deep. It’s so different to how Jimin usually fucks him, careful and precise, rolling his hips fluidly and smiling teasingly into a kiss. But right now he’s just a hole for Jimin, since all he cares about is emptying his seed into Jungkook and breeding him. Jungkook can’t find it in himself to care; the combination of the physical pleasure of his alpha thrusting over and over again into his prostate and the deep, purring satisfaction of his omega in his mind is powerful enough to drive him insane, eyes rolling back into his head as he takes and takes.
Jimin is almost feral at this point, sweat pouring down his face as he pounds Jungkook into the mattress. His alpha is restless, simultaneously satisfied with his work and yet needing more, needing to claim and mark and own. Roughly, he grabs Jungkook’s wrists and slams them down beside his head, pinning him down on the bed as he grinds deep into his core.
“Tell me who’s fucking you,” he snarls, his eyes bright and piercing into Jungkook, not letting him look away. “Tell me who you belong to.”
“You, you, please, alpha,” Jungkook sobs, writhing as Jimin keeps pressing his cock relentlessly into his prostate. “I’m yours, I’m yours, alpha, I belong to you. Please, breed me, please, fuck -”
Jimin growls deep in his chest, his pulse racing. He sits back on his heels and grabs Jungkook’s thighs, fucking back into him somehow even faster than before, albeit shallower now, stretching against his rim. Jungkook just mewls desperately, feeling tears start to slide down his cheeks as the pleasure fissions out into every inch of his body. His hole is completely soaked, gushing so much around Jimin’s cock that he can hear the wet squelch of his alpha fucking his own slick back inside him.
Jimin is delirious, and yet resolutely focused, his alpha’s need to breed the only thing he can concentrate on. He keeps thrusting almost mindlessly, pounding into his omega’s sloppy hole without even noticing Jungkook’s spasms and sobs under him, and finally he feels his orgasm start to approach as his alpha’s desire reaches its climax.
“Gonna knot you, baby,” he says, teeth clenched. “Gonna fuck you full of cum, gon’ breed you.”
“Yes, yes, want it, alpha,” Jungkook pants. He stares up at Jimin, tears spilling unbridled down his face, but with a hint of a smile on his lips. “Please, alpha. Want you to knock me up.”
That’s all it takes to push Jimin over the edge, groaning loudly as he leans down again to kiss Jungkook’s neck and thrust hard one last time into his tight hole. Hot, thick cum rushes inside Jungkook, and the feeling of Jimin claiming him with his seed, marking his insides, combined with his alpha’s knot catching against his rim, makes Jungkook come untouched, crying out as he’s fucked mindless.
Jimin pants into Jungkook’s neck, cum still spilling inside him, and to his alpha’s delight, he can feel Jungkook start to purr gently in his chest below him as he’s filled. His knot keeps swelling, and he can feel his cum start to drip down Jungkook’s thighs, the ridiculous amount meaning Jungkook can’t take any more. Its that thought - the knowledge he’s bred his omega as well as he possibly can - is what finally settles Jimin’s alpha, at least for now, and for the first time today, some of the frenzied brain fog of his rut starts to clear as his knot locks inside Jungkook.
He takes a deep breath, and brings his head up to look at Jungkook properly. As he meets his eyes, Jungkook instinctually bares his neck again in submission - but then he chuckles gently, his brilliant blue in his eyes started to fade a little now that he has Jimin’s knot firmly inside him.
“Hey there,“ he says weakly.
Jimin feels his heart lurch with love. He gazes down at him affectionately. “Hey, baby. You okay?”
Jungkook raises his eyebrows and snickers, his face still flushed red. “Yeah. I’m pretty fucking great, actually. You?”
“I’m pretty great,” Jimin smiles softly, settling down slightly on one side so he’s not having to hover directly over Jungkook. He brings a hand up to touch Jungkook neck, now littered with bruises, especially around his mating gland. Despite his alpha’s bliss, he feels his stomach twist a little. “Do you… was that good for you?” he asks, a little apprehensively.
Jungkook stares at him incredulously. “Are you kidding? I loved it. It felt great. Why, are you okay?” His face falls slightly, his eyes still a little glassy with tears. “Didn’t you like it? Did I do something wrong?”
“No! No, of course not, my baby. You were perfect,” Jimin reassures him hurriedly, berating himself internally for not being more careful. Jungkook was always a little fragile after sex, especially when one of them was in a heat cycle. “You were so good for me, made my alpha so happy.”
Jungkook preens at the praise, his eyes shining brightly. “I’m glad,” he says. “So what is it?”
“Just…” Jimin looks down guiltily at Jungkook’s neck again. “That was a mean trick with the mating gland. I knew you were just playing, but I forced you into submitting. I should’ve eased you into it, but I wasn’t thinking straight.” He bites his lip. “I’m sorry.”
Jungkook looks panicked, shaking his head fiercely. “No, no, don’t be sorry! Hyung, I wanted it. I was just teasing you, I promise. I was going to submit to you one way or another, you’re my alpha, and you’re in rut. I knew something like that might happen, I swear I did.” Jungkook leans up slightly, shivering a little as Jimin’s knot shifts inside him. He gazes into Jimin’s sorrowful eyes, now his usual deep brown. “I trust you enough to take care of me no matter what. And your patience is always non-existent during a rut, so what you did was totally understandable. I liked it - I mean, it was even…” Jungkook breaks the eye contact, face colouring even more. “I thought it was really hot, actually,” he says shyly.
Jimin relaxes, relieved he hadn’t hurt Jungkook. Then he processes what Jungkook just said.
“Oh?” he says teasingly. “Does my Jungkookie like it when his alpha puts him in his place?”
Jungkook blanches, then he whines, covering his face. “Don’t tease me,” he says pitifully, as Jimin giggles and pulls his hands away from his eyes. He glances down as Jimin strokes his cheek gently, studying between his legs where they’re connected. “How much longer do you think it’ll take for your knot to deflate? And for you to turn back into a sex-crazed maniac?”
Jimin sighs. “We probably have about ten minutes until the knot goes down, and then another ten minutes or so before the rut hormones kick in again.”
Jungkook nods. “Twenty minutes. I could nap for twenty minutes.”
Jimin smiles, his eyes creasing into half-moons. “Yeah, good idea. Get some rest,” he says tenderly, “and I’ll wake you up when I need to fuck your brains out again.”
Jungkook closes his eyes contentedly, nuzzling into Jimin’s neck. Jimin feels warm all over, but it’s not the rut this time. “Sounds like a plan.”
