tie those knots a little tighter

Summary:

He’s only been an omega for a short while. His first heat is approaching with the turn of fall to winter, and to top it all off he only has one arm. There’s nothing too terrible about that — except when you consider how difficult it will be to...to...satisfy his own needs.

Naruto looks at his pinned, empty sleeve. Just had to be the right one, didn’t it?

(Or, Naruto's told that heats are more manageable with a partner. He does not have a partner, but he certainly has one in mind.)

Notes:

A slight continuation of my previous one shot (aka the first in my ShikaNaru Week 2021 series) but not necessary to read before this. Still, if you wanna...

Prompt: (A/B/O) Knotting / Shikamaru Naruto

(See the end of the work for more notes.)

Work Text:

“—so then she told me it would be less painful if I have someone with me, but just thinkin’ about it is weird. Ya know?”

“Uh-huh.”

“Who would I even ask? Doin’ it with a friend would just be... ew, nasty, and there’s no way I’d ask a stranger. What if they had weird kinks?”

“Uh-huh.”

“Weird kinks, Sakura! Hey, are you paying attention?”

Sakura sighs, looking up from her work. There’s piles of paperwork on her desk and the sharp scent of her irritation mixing with the hospital’s haze of disinfectant.

“Naruto, if it’s making you that uncomfortable just spend your heat alone. And while you’re at it, leave me alone!”

Naruto yelps as the pen in her hand snaps, and dodges out of her office when she menacingly grips a poor potted plant. He disappears into the hallway, a scowl on his face. She’d been no help at all! Couldn’t she see how stressed he was?

He’s only been an omega for a short while. His first heat is approaching with the turn of fall to winter, and to top it all off he only has one arm. There’s nothing too terrible about that — except when you consider how difficult it will be to...to... satisfy his own needs. 

Naruto looks at his pinned, empty sleeve. Just had to be the right one, didn’t it?

He can feel his heat building. It’s instinctual. (And he has an informational package to tell him what signs to look for, but that’s besides the point.)

Without his consent, his scent has been blooming in heavy wafts from his flesh; announcing his lack of mate. It’s not anything that drives others into states of sexual arousal, like some poor works of fiction might say — cough, pervy sage, cough — but it makes people perk up and notice him. The point of a pre-heat scent is to announce his presence and his availability. 

Naruto would rather announce his availability verbally. Not that he really has a choice here. 

Then there’s the collection of pillows and blankets he’s piled into his room, the jittery feeling in his bones that comes from having excess energy and no idea what to do with it. Naruto runs his hands through his hair as he exits the hospital. At this point, his heat will probably hit within the next day, and he’s got no idea what to expect.

Well, he has an idea, but experiencing it is something different entirely. He’s...not scared, because he refuses to be, but he’s...cautious. All the information he’s been given states that he shouldn’t lose his mind, he shouldn’t black out, he shouldn’t lose control of his body and become a horny ball of slick and desperation — which he’d never judge someone for. Applying that to himself, however….

Naruto doesn’t like the idea of not having full control of his mind.

You worry to much, Kurama rumbles in his head, Just fuck that deer brat and get it over with.

“What?”

What?

Naruto trips over nothing, flailing his arm and a half for balance. His face heats to a ruddy red, “Kurama!”

He gets some odd stares from civilians, but can’t bring himself to care. 

What? You know I’m right. You’re being ridiculous, you emotional little worm.

“I’m being — me? You just suggest that I — with Shikamaru!”

As if you’d mind! With the way you stupid humans sniff around each other you may as well be courting already.

Naruto shrugs his shoulders up to his ears, grumbling to himself. The flush has yet to leave his cheeks, and at Kurama’s words they only flare up again. So what if he likes the way Shikamaru smells? So what if they nap and cuddle together, or stare into each others eyes, or go out to eat and —

Ok, so maybe he kind of sees Kurama’s point. But none of that had been romantic! Probably. Or Naruto’s just an idiot.

He sighs.

Could he really be considering it? Asking Shikamaru to...to…

Dark, strong hands on his waist; a sharp amber gaze softened by dancing pheromones, pinning him to the bed and stealing the air from his lungs. A smirking mouth close to his own, dark hair between his fingers, something hot and big slipping into that untouched hole—

“Gah!” Naruto shrieks, nearly pulling his hair from his scalp. He runs into a lamppost with Kurama’s laughter in his ears.

 


 

He can’t afford to waste time, even if he is embarrassed. His heat comes tomorrow, whether he wants it or not, and he can’t be walking the streets blasting those kinds of pheromones while slick drips down his legs. 

Naruto ignores Kurama and his own embarrassment. He walks right into the Nara clan compound with his head held high and tries his best to ignore the stupidly knowing eyes of everyone he passes on the way to Shikamaru’s house. It’s like all the Nara share some creepy hive brain, with the way they all look at him with the same damn expression. He walks a little faster when one of them gives him a thumbs up.

“Shikamaru!” He yells, because if everyone else already knows he’s here then it’s not like he has to worry about volume control. He knocks his fist against the door to his friend’s home, and forgets for a moment that the alpha doesn’t live alone.

Yoshino opens the door.

“Oh, Naruto!” She presses a hand over the bottom half of her face, but the smile is obvious in her tone, “What a surprise! Are you looking for Shikamaru?”

“Um, yeah. Yes. Does he...uh, well, is he here?”

He can count the number of times he’s interacted with Shikamaru’s parents, so he feels a bit awkward. They treat him well, though, and he’s actually been seeing them around more often in the past month…

“Of course,” she smiles at him, then looks over her shoulder to scream into the house, “SHIKAMARU GET YOUR SORRY ASS DOWN HERE RIGHT NOW!”

Naruto flinches. Shikamaru’s mom was scary.  

She turns back to him with another kind smile when a thump is heard from deeper within the house, “He’ll be here in a moment. Can I get you anything? Tea, a snack? Blanket? Having any cramping?”

“No, no,” he waves off the alpha woman’s kindness sheepishly, “Really I just wanted to...er, talk to Shikamaru. I don’t wanna be here too long — no offense!”

“Oh, I understand!”

Shikamaru finally wanders into view, face pinched and his clothes rumpled. It looks like he’s just woken up.

“What is — oh. Naruto.”

Naruto brightens, his pheromones unfurling like a flower under the sun. Ocean salt and citrus, summer haze and sunshine; it spills into the air, beckoning and sweet. Shikamaru wanders all the way over in a daze, barely noticing his mother step back to let him by. She watches the two of them with sparkling eyes, hands clasped to her chest like she’s witnessing a miracle.

“Hey,” Naruto says, suddenly feeling shy.

“Hey.”

They stand there for a moment.

“Um, I was wondering...if…”

More silence.

Shikamaru takes a breath and turns to his mother, “Mom, do you mind?”

“Oh, not at all, say what you need.”

“Mom.”

“Iwaswonderingifyou’dspendmyheatwithme!” Naruto blurts out.

“I’m — sorry, what?”

Yoshino rolls her eyes, “Oh, for Sage’s sake. Yes, Naruto, he’ll happily take care of you during your heat. Won’t he?”

She elbows Shikamaru, who looks like a deer caught in headlights. The words sink into his head slowly, that genius brain of his stuttering to a halt. Once he’s picked them apart and understood the meaning, he blushes violently to the roots of his hair.

“You, you want, we, uh, me, we’re, you—”

Naruto shuffles, “If you don’t want to, that’s fine! I just thought I’d ask—”

Maybe his disappointment is obvious, heavy in his tone or his scent, because Shikamaru suddenly rises from his usual slouch with an embarrassed, determined expression.

“No, I’ll do it.”

“Really? It won’t be...troublesome?” Naruto smiles cheekily. His relief is palpable.

Shikamaru goes back to slouching, “Oh, probably. But I wanna do it anyway.”

They stare at each other, Naruto’s azure gaze bright and adoring, Shikamaru’s soft like pools of melted gold. The moment is ruined when Yoshino claps her hands.

“Oh, I’m so happy for you two! Shikamaru, you better treat him right, you hear me?” She turns to Naruto, “So how many children were you thinking?”

“C-children?” He squeaks.

 


 

His heat sets in around breakfast time the next day. He manages to swallow down food and scrub his body clean (again) before the worst of it hits. The cramps are sharp and rolling, surging back and forth from manageable to bad diarrhea. He feels warm, but that’s to be expected.

Wearing clothes is starting to grow uncomfortable, so he’s glad when Shikamaru finally knocks at the door. He’s not so out of his mind that he’d strip beforehand and answer it naked. Actually, aside from the discomfort and low fever, he doesn’t feel out of his mind with lust. A little horny, maybe. Slick has already started to pool between his cheeks. It’s not — well, it’s not as scary as he’d thought.

“Hey,” Shikamaru says gruffly, quickly shutting the door behind them before too many of Naruto’s heat pheromones escape. Seals are activated to prevent any scent or sound from leaving the apartment — a standard for privacy and safety during heats.

“Hi,” Naruto replies, stupidly breathless at the sight of the other man. There’s nothing different about Shikamaru, but he suddenly looks and smells so enticing that it makes Naruto’s cock swell in an instant. A new gush of slick leaves his hole, soaking down his thighs to leave a damp spot on the seat of his pants. 

Shikamaru’s entire body tenses like he’s been shocked, narrowed eyes blown wide while his pupils shrink. The scent of smokey wilderness and spice grows so heavy that Naruto feels as if he’s swallowing it.

“Are you...you’re really sure about this? About me?”

“Yeah,” Naruto says, and realizes quite suddenly how much he means it, “I really, really like you, Shikamaru.”

“You….” Shikamaru flushes, rubbing the back of his neck, “That’s. Yeah. Me too.”

“You like yourself?”

“Troublesome.”

Naruto laughs and leads the alpha into his bedroom. His bed is piled with blankets and pillows, organized to leave a comfortable space for them to lay. The kitchen is stocked, as is the bathroom and his drawer of condoms — Sakura, even if annoyed by his whining, helped him prepare for this. 

It’s awkward, but at least they know each other. Naruto strips because his threshold for shame is greater than Shikamaru’s, proven when the alpha turns away to give him space before remembering what he’s here for.

Naked as the day he was born, Naruto hops onto his bed and...waits.

“Well, come on!”

“I’d rather this not feel like a business transaction,” Shikamaru drawls, stripping carefully out of his own clothes. 

“Then hurry up and kiss me or something!”

Another cramp hits him. Though soothed by Shikamaru’s scent, he still feels an intense discomfort.

“Alright?” Shikamaru crawls over him, naked as well.

“Yeah, just cramps.”

They stare at each other for a bit, enamored by open planes of skin, softness and muscle. Naruto brushes his hand up Shikamaru’s chest and grabs at the Nara’s neck. 

“C’mon, I said kiss me!”

“Fine, fine,” Shikamaru leans down.

Their mouths slot together slowly. For a first (real) kiss, it doesn’t feel like much at first. But then they shift, find angles that feel better, and the slick slide of their mouths begins to send little shockwaves down his spine. The kiss deepens, and hands begin to wander.

Naruto only has one, but he uses it to touch whatever he can. Skin, hair, the curve of Shikamaru’s jaw — he groans as his head grows heavy and clouded with the combination of their pheromones and his own deepening lust.

Shikamaru’s nostrils flare as the intoxicating sweetness of omegan slick amplifies. He grabs at Naruto’s flesh carefully at first, but it’s obvious he’s growing more interested the more they kiss and touch.

Naruto decides to change up the pace. He licks at Shikamaru’s lips until the alpha opens up, and their tongues press wet and messy into each other’s mouths. Drool leaks down his chin and he can’t bring himself to care.

He wriggles under the alpha, keening as his heat ramps up. When their mouths separate he gasps for breath, “Shikamaru, c’mon, don’t treat me like I’m fragile! I know you’re a lazy bastard but—”

“Geez, I get it!” Dark hands slip down his waist to grasp at his legs. Shikamaru pushes tanned thighs up, his entire face scarlet as he looks down at Naruto’s most private parts.

They both swallow, but embarrassment is overridden by lust and heat. Naruto pulls his own legs to his chest with his arm, stump splayed out to the side. His core throbs, this time in anticipation. Wet and glittering with slick, Shikamaru feasts his wide gaze on the offered hole.

Er, holes?

His hands trail down Naruto’s flushed cock and balls, then lightly touch the quivering opening just below. Another gush of slick spills onto his fingers, and Shikamaru shivers.

A low rumble builds in his chest, and Naruto gasps at the sudden spike of alpha pheromones — protective and heavy, like a weighted blanket. Shikamaru looks shocked at the sound coming from his own body, but ignores it and begins to push his fingers inside.

Quivering at the sensation, Naruto tightens his grip on his legs as Shikamaru begins to thrust his fingers in and out. Slowly, carefully, feeling around with obvious interest. They press firmly into Naruto, long and calloused. A wet shlick sound builds, slick continuous as he grows more aroused. 

Shikamaru fingers him open with intense concentration, picking apart Naruto’s reactions with sharp eyes. He’s always been the type of person to think of a million different paths before taking one. He catches every detail, every twitch, every bead of sweat. 

When Naruto keens and whimpers in pleasure, Shikamaru rubs his fingers over the same area that brought about such a sound. It gets to the point where they both become consumed by Naruto’s heat, their cocks heavy and leaking; cheeks flush, chests heave and desire coils like molten lava in their stomachs. 

“Hurry up!” Naruto wiggles his hips, “I’m ready! You’re taking too long!”

“I’m being careful! It’s your first time and I don’t want it to hurt—”

“My first time? What about yours?!”

Shikamaru recoils at the sharp possessiveness in Naruto’s voice, quickly sending out soothing alpha pheromones, “Don’t be stupid, it’s my first time too.”

“...good,” Naruto huffs, “You’re only allowed to do it with me.”

“Sure that’s not just the heat talking?”

Naruto lets go of his legs to grab at Shikamaru, “I said I like you! What else do you need to understand?”

“Yeah, yeah, I know. I get it.”

“Do you?”

A fond sigh, “Yes, you troublesome little shit.”

“Then,” the blonde spreads his legs, “fuck me already, alpha.”

Shikamaru shivers, his scent flaring sharply. His lips curl back to flash his canines, and for a moment there’s a sliver of intent in his amber hues that has Naruto quaking and eager. Then the Nara presses in close, the blunt head of his cock bumping the slick covered folds of Naruto’s entrance. 

“You’re so impatient,” Shikamaru practically snarls, his voice more strained than Naruto has ever heard it, “Maybe I wanted to take my time.”

“Later, I want your cock inside now.”

“Great Sage, you’re the biggest pain in my ass.”

His cock begins to enter, slipping inside very slowly. Even with the stretching it’s a tight fit, and Naruto forces himself to relax. Shikamaru holds his legs open, thumbs digging into the soft flesh by his knees. He grits his teeth in pleasure while playing close attention to Naruto’s face, searching for signs of pain.

The path is soothed by Naruto’s heat and the exorbitant amount of slick pouring out of him. There’s not much pain to be found, instead they both moan in unison as Shikamaru bottoms out. His pelvis is pressed flush to Naruto’s hips, and the omega feels his entire body let out a shudder.

He feels full. Hot. The cock inside him throbs, and suddenly Naruto doesn’t care about control. Sweat pours from his body and every bit of his flesh is flushed. He can feel his pulse throb in his throat and swallows against the dryness he finds there. 

“Good,” he slurs, “Oh, Sage, it feels good—”

Maybe it’s the pheromones, but he already feels better than he’s ever had when jerking off. Naruto rocks his hips against Shikamaru’s frozen form. He clenches his hole down on the thick cock just resting inside of him, desperation mounting.

“Fuck me already!’ He snaps, “C’mon, Shika! Fuck me, fuck me, fuck me—”

Shikamaru growls, the smokey tone of his voice turned to gravel. He leans his weight forward, Naruto’s legs curved over his shoulders. Without pause, he begins snapping his hips with vehemence. The first thrust makes Naruto yelp.

He reaches up to grab at Shikamaru’s shoulder, blunt nails pressing into brown flesh. Shikamaru fucks him earnestly, cataloguing everything with those glittering, tawny eyes of his. He puts that high IQ to use, and in any other case Naruto would feel like a bug under a microscope. Instead all he sees, feels, smells and tastes is alpha.

He screams it, revels in it. Kisses when Shikamaru leans close, moans into the other man’s ears, leaves red lines down the alpha’s back. 

“Ah, hn, oh—” His legs snap around Shikamaru’s back and he rocks his own hips to meet the alpha’s hard thrusts, “Deep, oh, deeper, deeper, Shikamaru!”

Shikamaru grits his teeth, angles his hips, and renews his thrusting with a rabid, animalistic tenacity. Very rarely does he put so much effort into something, and Naruto feels his heart clench painfully — in the best way — when he realizes that maybe he really is important to the alpha. Maybe Shikamaru really does like him back. 

Maybe they can...be together. 

“Naruto,” Shikamaru gasps by his ear, voice so deep it sends shivers down the omega’s spine. He licks at the scent glands on Naruto’s neck, sucks at the fragile flesh. His moans grow wilder as he grows high on the overwhelming and consuming scent of a happy, pleasured omega in heat — a wailing, messy, orange-loving, unmated omega.

Hazy, everything is hazy, yet the pleasure is bone deep and intensely clear. Shikamaru pulls away for a moment, letting himself be alpha in a way he never has before. He’s not the type of person to care about designations. No one expected him to be an alpha, even with two alpha parents. No one outside of the Nara clan, that is. He’s sure his parents saw it coming a mile away.

Now he’s truly acting the way he was born to, the way nature intended. He wants to fuck his omega until Naruto screams and gurgles and cums. Then they can sleep for a year. Maybe after, Naruto can fuck him. He won’t be picky. He just wants. Alpha-Omega be damned, the only good thing about it is this; these feelings swirling between them. The fact that they can mark each others skin permanently and Shikamaru can pour cum into Naruto’s womb to breed him, make him bear the alpha’s children—

Naruto whines when he pulls away, but purrs when Shikamaru rolls him over. Perhaps in tune with his alpha’s instincts, or in tune with his own omegan ones, Naruto arches his spine and presents himself without being asked. His ass is pink and plump, wet and glimmering under the room’s shitty lighting. Shikamaru swipes a slick finger over Naruto’s tightly puckered asshole and thinks next time.  

Next time, when they have more patience. He can lay back and let Naruto ride him until they both come. Whichever hole. One and then the other. It really won’t matter. Shikamaru just wants to pick apart every piece of the blonde until he knows everything about him and which spots make him cry. Sage knows the blonde would have the energy for it. But this time…

He lines his cock back up to the open, gaping slit and thrusts all the way in with a single push.

“Fuck!” Naruto keens, face pressed into the sheets. He grabs at the fabric with his hand, drooling all over his bed. His azure eyes are foggy and shining like polished stones plucked from the sky. 

Sweat slipping down the knobs of his arched spine, ass cheeks bouncing with every sharp thrust — Shikamaru is struck with the lewd thought that omega has never looked more beautiful. Naruto moans without shame, chases Shikamaru’s cock without shame; he is unabashedly Naruto without fail. 

And he’s begging for Shikamaru to fuck him harder, faster, deeper; he wants Shikamaru to abuse his tight little hole, to steal away his virginity and sink his seed deep inside that new, untouched womb. 

It feels so good — Shikamaru thinks he might go crazy. This is why alphas kill for their mates.  

The room fills with their grunts, gasps and moans, the slap of their skin and the slam of the bedpost against the wall. He’s mesmerized by the way Naruto’s hole keeps sucking him in, driving him delirious with a feral sort of lust. Naruto tilts his head and meets his eyes.

The same stunning azure gaze, his face a mess of drool and tears and sweat. He’s wet all over, between his thighs and across his skin. Shikamaru licks the salt from the blonde’s shoulder. He inhales deeply and brushes his nose along the curve of Naruto’s neck.

“Shikamaru,” Naruto whimpers, “I feel — I feel like, ‘m goin’ crazy….”

Lightning surges through his veins. Every thrust of Shikamaru’s cock drags against sensitive, throbbing bits within him. He can feel the head of his alpha’s cock brush right up against his womb — or at least, that’s what it feels like. He’s just so full, heat pulsing through him in waves. Everything tingles, everything aches in the most pleasurable of ways. If he could feel like this forever, he would. He’d bend over every morning and let Shikamaru stuff his way inside. He’d go to sleep every night wrung out and pumped full of cum.

“Good, ‘s good, want it, yeah, hn,” he doesn’t even care what he’s saying at this point, “please, please, please—”

Shikamaru presses him into the bed, hips snapping erratically, “I have you, I have you.”

His knot begins to swell at the base of his cock. There was no way in hell he was going to last long the first time. Maybe not ever, with the way Naruto’s hole squeezes — hot and slick and throbbing in the best way. His knot starts to catch on the ring of muscle just within the slit, stretching Naruto open even further.

The blonde shrieks louder, tearing at the sheets with his hand.

“Inside, inside!” His womb feels so empty.

“We, we don’t — ngh, we don’t have a condom—”

Naruto glares at him with heat rage over a sweaty shoulder, “Fucking breed me, alpha!”

Shikamaru snarls back, alpha pheromones flaring once more. “You little—”

“Mate me, mark me,” the blonde continues, the aggression simmering down into lustful desperation. He shakes his hips and clenches down on Shikamaru’s cock and knot, “Shikamaru, please, love you—”

Shikamaru nearly cums. He swiftly reaches around to grab Naruto’s neglected dick, jerking it off harshly in time with his thrusts. The omega screams, his body seizing as his eyes roll up. His spine arches sharply and the cock in Shikamaru’s hand pulses, cum shooting out all over the sheets. Naruto clenches down so tightly during his orgasm that Shikamaru almost immediately follows behind.

His knot catches and locks them in place. With a few shallow thrusts, an intense wave of euphoria and belonging crashes over him, whiting out his vision. His balls draw up tight as he empties into Naruto, spurt after spurt of hot cum pouring into the omega’s womb. He keeps cumming for a while, body naturally reacting to the heat signals pouring from Naruto. The alpha in him wants to be sure his seed catches. He wants Naruto swollen with their children.

Shikamaru’s muscles tremble. Exhausted, he slumps to the side, keeping his touch gentle as he spoons Naruto. The omega’s body still shakes with the aftermath of his explosive orgasm. Periodically, his hole clenches down on Shikamaru’s pulsing cock to squeeze out another dribble of cum. 

They breathe.

“Why didn’t you bite me?” Naruto finally whispers.

Shikamaru stares at the back of Naruto’s head, he can see the disappointed line of the other man’s shoulders, smell it coming off him.

“I just...thought it should be something we talk about first.”

Naruto’s chest clenches. He feels so good — everything was so good, but…maybe he’s more insecure about Shikamaru’s returned feelings than he thought.

“Do you not want to?”

“You’re so troublesome. You think I’d put in the effort to knot you if I didn’t want to keep you forever?”

Naruto’s ears burn red. He can’t keep the giddy smile from blossoming over his abused mouth, “Really? You really mean that? I’ll be pissed if you’re joking, ya know!”

“You should know me better than that, idiot.”

“Ehe!”

They lay there, content, the issue settled for now. The aftermath is hazily pleasurable, enough that they don’t even feel like moving. Shikamaru isn’t sure he even can move. It’ll take a bit for his knot to go down, so at least he gets a breather before Naruto’s heat starts again. 

He sighs and presses his nose against the sweaty back of Naruto’s neck.

“If you’ll have me….I’d like to be your mate.” It’s embarrassing to say out loud, but once it’s out it’s over. At least they aren’t facing each other. 

Naruto inhales sharply, then laughs so brightly he might as well replace the sun, “You’re never gettin’ rid of me!”

“...troublesome.”

 


 

“So...what your mom said about kids…”

“Please don’t mention my mother while my dick is inside you.”

“Right, right, good call….but have you thought about it?”

“Naruto.”

“Okay, okay…...I want at least two, ya know.”

“...fine.”

“Maybe more.”

“Well I’m not going to say no to fucking you.”

“Shika, you’re kinda pervy, huh?”

“Please….stop talking...let me nap…”
