Something is wrong with Naruto.
Three days ago, Kakashi came to them with a mission. The Hokage had gotten reports of unusual activity outside the border of Takigakure. They requested the help of the Leaf village to scout around for a few days and keep watch.
It's a five day trip traveling there by foot. Typically, Naruto jumps with excitement at these opportunities. Getting away from the village alone with Sasuke; Naruto prefers it that way.
Sasuke doesn't mind. He wouldn't say he gets overcome with joy like the idiot does, but he'll reluctantly admit it's always better when it's just the two of them. They understand each other better than anyone else and never have to worry if the other can keep up. They can match each other perfectly. It makes the possibility of running into trouble not seem so bad. With Naruto by his side, they're unstoppable.
Each day of the trip so far, Naruto has gotten progressively more agitated. Quick to lash out at the smallest thing. With them both being Alphas, they are no stranger to constant fighting between each other. But this is different. Naruto's never this grumpy. His agitation has been fueling Sasuke's own, making it impossible to relax.
They still have two days before they make it to Takigakure. Sasuke doesn't think he can put up with this behavior anymore. It's starting to make him feel antsy for a fight.
Naruto aggressively stomps forward to Sasuke's left, Tight tension seeping through his body.
Sasuke stops walking and turns to him. “Hey, I think we should stop here.”
“No, let's keep going.”
“Naruto, what's wrong? Why are you acting like this? You're really starting to piss me off.”
Naruto continues to walk past Sasuke. “I'm not acting like anything, leave me alone.”
Sasuke reaches out to grab Naruto's arm to stop him. “Dude. Seriously.”
“Don't touch me!” Naruto yells and angrily rips his arm away.
Sasuke is only stunned for a moment before he lunges forward and shoves him away. The unexpected attack throws Naruto off balance. He manages to catch himself and whips around, throwing a punch directly at Sasuke's face. His head jerks back at the contact. Immediately, he feels the blood rushing from his nose and down his face, staining his shirt.
“What the hell!?”
Sasuke grabs hims and kicks his legs out from under him, toppling him to the ground. He quickly jumps on top of him to hold him down. The blood from Sasuke's nose now dripping all over them both.
Naruto's Alpha instincts start to flare. His eyes take on a deep red color, his fangs sharpening and coming out.
Under Sasuke's palms, he can feel Naruto's nails getting sharper, too. He braces himself for the counter attack he knows is coming.
Naruto rocks them, creating leverage to buck Sasuke off him. He flips them over and pins Sasuke down, arms above his head.
With his wrists locked, he has no way of defending himself from an attack. Instinctively, he turns his head and scrunches up his face, anticipating another punch to his nose.
None comes.
Instead, Sasuke feels what appears to be Naruto grinding down into him.
What the fuck??
Suddenly, the smell of lust is heavy in the air. Sasuke can feel Naruto's hard length as it rubs against his ass. Sasuke's eyes snap back open and he whips his head to look down.
“What are you doing? Stop! Get off me!” Sasuke starts fighting back against his hold.
Naruto keeps moving, setting a rhythm with his hips. He looks dazed, like he doesn't even realize where he is.
Realization dawns on Sasuke. “Are you going into rut?” He tries to hide the small bit of panic he feels at the notion. “What the fuck, Naruto. Where are your pills?”
The smell of his pheromones is filling the air, becoming suffocating. Sasuke's head is pounding and his own Alpha instincts are desperate to fight back; To assert dominance and control the situation.
He struggles against Naruto's hold. Sasuke watches as sick satisfaction flares through Naruto's eyes as he fails to break free from his grip. He leans forward and buries his nose in Sasuke's scent gland, inhaling deeply.
Shuddering, he groans in his ear, “Sasuke…”
He glides his tongue across his throat before latching on. Sasuke arches into the touch, an involuntary gasp escaping his lips. Naruto moans at the response and loosens his grip.The action allows Sasuke to rip his hands free. He reaches down, wrapping his fingers around Naruto's waist, before lifting and getting his knee in place to ram it straight into his dick.
Naruto cries out in pain as Sasuke throws him off and jumps up, quickly backing away.
“What the hell, Sasuke? Why did you do that? Shit!” Naruto doubles over, clutching his crotch.
“You were trying to fuck me!” Sasuke yells back.
“No I wasn't!”
Sasuke turns away, trying to calm his racing heart and the unexpected heat pooling in his stomach.
“Are you in rut right now, Naruto?”
There's no reply.
Sasuke runs his hands down his face in irritation and turns back around. “We can't finish the mission with you like this. It's too dangerous. Where are your pills? You need to take one now. Then hopefully you can just sleep this off and we can continue on our way tomorrow.”
“I don't have my pills…” Comes his quiet response.
“What do you mean you don't have them?”
“I lost them… but I thought it would be okay! We were supposed to be back in time before this happened. It's not my fault I went into rut early!”
Sasuke groans. “Let's just set up camp here. Keep your tent away from mine. I don't need you trying to rape me in my sleep.”
“Ya right. Like I'd want to touch a gross Alpha like you.” Naruto says sourly.
Sasuke walks to find a stream to clean up the blood while Naruto clears out the area.
They set up their stuff, and Sasuke sits down to make dinner. Naruto finishes his meal quickly before crawling away to hide in his tent.
Sasuke tries to lay down and sleep, but it's impossible with all the noise Naruto is making from constantly tossing and turning.
Despite putting his tent as far away as he could, Naruto's pheromones are still heavy in the air, clogging his nose and throat. Alpha pheromones are typically off-putting for other Alphas. They signal aggression and danger. During a rut it's worse. Their fumes are fighting for dominance over others, and if you aren't careful, you could be forced into submission.
Naruto, however, smells nice. Almost…Enticing. He guesses that's to be expected. For as long as he's known Naruto, his scent has always been different from other Alphas. When they first met he actually thought Naruto was an Omega with how sweet his scent was. No one else seemed to notice, though. Sasuke decided to never bring it up. He wasn't about to admit that another Alpha smelt good to him. With how much time they have spent together over the years, it's grown to become a comforting scent. It's even been helpful in battles, being able to distinguish where he is at all times and if he's in danger. Despite their close friendship, he's never smelt Naruto in rut before. It's typically always been something he can get over relatively quickly.
This time is different. They are stuck in the middle of nowhere with nothing to help. No rut suppressants and no Omegas. Even if there was an Omega present, Sasuke knows Naruto wouldn't use them to help. He's always been weird about it, preferring to be alone for his ruts.
Though the strong fumes in the air are bringing out aggression in Sasuke, it also makes his head spin in different ways he can't really explain. It's overwhelming, and he feels like he's being lured into danger.
He can hear Naruto groaning in pain. Against his better judgment, something pulls him to get up and walk over there to check on him.
He stops just outside the tent to call out. “Naruto..?”
“Go away.”
Ignoring him, Sasuke unzips his tent and crawls in. The scent of the room makes his nose wrinkle. It reeks of desperation and loneliness. Naruto sits miserably in the corner clutching his pillow, shaking. His cheeks are red and damp with sweat, blonde locks sticking to his forehead. He rolls onto his back as Sasuke gets closer. The new angle gives Sasuke a full view of his dick straining inside his pants. His eyes are drawn to the tip and the wet spot around it.
“Why don't you just masturbate. I don't want to be stuck here forever, and I can't sleep with you making all this noise.”
“Sorry my pain is an inconvenience to you.” Naruto sneers. “Jerking off doesn't work, it won't go down.” He palms his dick and starts to absent-mindedly roll his hips against it. The motion makes Sasuke's mouth go dry.
“Are you sure you're doing it right?”
“Sasuke, I swear to god I'lll kill you if you don't get out right now.” His voice comes out strained as he pushes down harder on his dick.
He watches him for a second longer before turning around.
“Whatever.”
Sasuke quickly leaves and goes back to his own tent.
Despite Naruto saying masterbating doesn't work, Sasuke can hear him try anyway. Wet noises and groans fill the otherwise quiet night air. Sasuke can't help but notice it's just like the noises Naruto makes when they fight. His body heats up from the thought. He wonders what Naruto looks like. He'd be lying if he said he's never thought about it before during his own desperate ruts. Is his face all scrunched up in pleasure as he rapidly pumps his cock in his fist? What does he think about? Does he imagine someone else touching him instead? Sasuke refuses to allow himself to think about anyone else touching him during his own ruts. He can't. If he does, all he will be able to see is flashes of blonde hair and a big, dopey smile and it freaks him out so bad he panics and stops.
He hears Naruto's moans become uneven in what must be him reaching his climax. He quickly turns over and covers his ears, ignoring the hardness in his own pants.
~•~
The next morning isn't any better. Sasuke hardly slept and can already feel a headache coming on from having to deal with Naruto like this for another day.
Naruto stays in his tent, refusing to come out. When Sasuke makes ramen for dinner and Naruto still doesn't come out, he starts to feel a little concerned.
Hesitantly, he walks over to his tent and peaks inside. Naruto lies in a big heap, hiding under his blanket.
“Are you okay?”
No response.
“I made you ramen.”
“I'm not hungry.” Naruto mumbles out.
“Since when?”
Again, No response.
Annoyed, Sasuke crawls in and pulls the blanket off of him. Naruto lays there in nothing but his ridiculous bright orange sweatpants. His broad chest flushed and on display. Heavy dark circles under his eyes tells Sasuke he didn't sleep well either.
Naruto angrily rips the blanket back, covering himself. “Go away Sasuke! You just make everything worse.”
“How do I make everything worse? I'm trying to help you.”
“This is how you help? By messing with me and annoying me?” He rolls over, avoiding Sasuke's gaze.
Mumbling, he says, “If you really wanted to help, you'd let me fuck you.”
“What.” Sasuke sits back, frozen in shock.
Naruto slowly turns back over and looks up at Sasuke. The brilliant blue of his eyes is overwhelming and Sasuke scrambles to the furthest side of the tent to get away from the intensity of them.
“I'm an Alpha! You can't fuck me!”
“Why not?” Naruto teases. “You're pretty like an Omega.” He gets up on his hands and knees and starts to crawl towards Sasuke.
His heart feels like it's beating through his chest as Naruto reaches out to touch him. Panicked, Sasuke throws a punch at him. Naruto dodges it with ease and smiles, excitement lighting up his face.
Sasuke feels a sense of dread at the expression. Why did he come in here? Narutos blocking the door. The only way out is to fight through.
Sasuke lunges forward and pushes Naruto to the side, then rushes forward to get out. Naruto grabs his ankle and pulls him back, crawling on top of him to hold him still.
He leans down to whisper in his ear. “Sasuke. Please help me. Then we can leave.”
Naruto's hot breath on his skin sends a shiver down his spine. He might be annoying, and irritate him every second of every day, but he's still his best friend. Seeing him in pain like this hurts Sasuke in turn. He's also starting to get concerningly confused being around Naruto like this. It needs to end so they can go home and put space between them as soon as possible.
“Fine.” Sasuke grits out.
“What?” Naruto pulls back shocked, clearly not expecting that answer. “Are you serious? I was just joking around with you.”
“You don't want to do it then?”
“I didn't say that!”
Sasuke pushes him off. He knows that isn't the case. The scent of his arousal has magnified, hanging heavy in the air like smoke. His heart starts to race with a mixture of nerves and the shameful thrill of being touched by him.
“Shut up before I change my mind.”
Naruto just sits there stunned. Mouth hanging open in disbelief.
Sasuke sits up. “I'll just get on top of you or whatever and you can hurry up and do it and we go home and never speak about this again. Got it?”
“Okay…” Naruto breathes out.
They sit there for a while just staring at each other, neither moving. It feels like there isn't enough oxygen in the air. Sasuke starts to breathe heavily, fighting to get air in his lungs that isn't clouded with Naruto's strong, musky pheromones.
“So, are you gonna take off your clothes?” Naruto asks.
Sasuke rolls his eyes and feels his face get hot. In fact, his whole body starts to heat up and his clothes suddenly feel too tight and clammy around him. They have taken their clothes off in front of each other countless times before, but doing it in front of Naruto now makes Sasuke feel nervous. He keeps his hands as steady as possible as he lifts his shirt over his head. He can feel Naruto drinking him in. Eyes darting across his pale chest. He takes a deep breath and quickly pulls his pants off next.
Sasuke makes the mistake of looking up into Naruto's eyes as he throws his pants off to the side. The expression he sees there scares him as much as it excites him. Naruto looks like a starved predator that has just laid eyes on its prey. He looks at him like he wants to devour him.
Naruto's hands are shaking as he grips the blanket under him till his knuckles turn white. The energy between them is so heavily charged Sasuke almost doesn't know if Naruto's gonna hurt him or not.
Naruto slowly slips off his own pants, never taking his eyes off Sasuke. He can't help dropping his own eyes down onto Naruto's body. He's always been strong, stronger than Sasuke at times. It's never failed to bring out jealousy in him, pushing him to fight even harder to surpass him. He doesn't feel jealous now though. Instead, he feels intense desire.
“Okay, lay down.” Sasuke says with a slight waver in his voice.
Naruto smirks at him and surges forward, capturing his lips in a kiss. Sasuke gasps into his mouth, eyes wide.
Instinctively, Sasuke goes to push him away but Naruto wraps his arms around him, pulling him closer. He licks against Sasuke's lips, asking for permission inside. Sasuke opens his mouth and their tongues tangle together. A moan slips from Naruto and vibrates through Sasuke. For a man who's never kissed anyone, Naruto sure is doing it well. Sasuke almost feels like he's the inexperienced one, the way Naruto is taking charge and leading.
He feels Naruto sink his teeth into his bottom lip and Sasuke can't hold back the tiny whimper that escapes him. At the noise, Naruto pushes him down to the ground, climbing on top and kissing him more desperately.
The smell of lust in the air combined with the weight of Naruto's naked body against him is making his head spin. He should feel repulsed, but he finds himself getting more turned on.
Naruto moves down and mouths at Sasuke's scent gland, licking and humming against it.
“You taste so sweet.”
He runs his fingers up into Sasuke's hair and roughly pulls his head to the side to get better access as he bites down onto his neck. A whine gets caught in Sasuke's throat as shockwaves of pleasure shoot through him. He can feel precum bead at the tip of his aching cock.
Naruto pulls back and hooks his fingers into Sasuke's boxers. “Tell me now if you change your mind. I don't think I'll be able to stop otherwise.”
Sasuke's heart is pounding in his ears. “Just hurry up,” he whispers.
Naruto slowly slides his boxers down and off his legs. His dick sprangs free, painfully hard and leaking. Sasuke turns over in embarrassment, refusing to acknowledge his body's reaction to the situation.
Naruto stares at him, face full of hunger. He runs his hands down Sasuke's body before flipping him over onto his stomach. As he manhandles him to lift his hips up, Sasuke tries to protest and move into a different position.
“What are you doing?”
“It'll be easier this way.” Naruto grabs his hips tightly, stopping him from shifting away.
Sasuke feels intense embarrassment, being put on display like he's some kind of Omega. It's insulting and degrading. All of his instincts are screaming at him to fight back.
Naruto leans forward, pulling Sasuke's cheeks apart and gliding his tongue across his hole. Sasuke jerks forward at the unexpected sensation. Naruto just grips him tighter, holding him in place as he circles his tongue around more before pushing in, breaching his entrance.
Sasuke buries his face in the pillow. Fighting as hard as he can to silence the noises escaping his mouth as Naruto fucks him with his tongue. He's never been touched like this before. Has never even considered wanting to let another person do something like this to him. It feels wrong, and with each moment of pleasure he feels shame from how much he enjoys it. He reluctantly arches his back, pushing his ass higher in the air, seeking more.
Naruto hums and reaches his hand around to grab Sasuke's dick.
“No, d-dont!”
Sasuke comes all over Naruto's hand. It's so sudden, he doesn't have time to hold back his loud moan. Stars dance behind his eyelids as pleasure explodes throughout his body, turning him into a shaking mess.
Naruto catches it all in his palm and brings it back around, spreading his cheeks and rubbing it on his ass. Sasuke blushes in embarrassment at the sticky, wet feeling.
“Try and stay Relaxed, okay?”
Naruto circles a finger around his hole, rubbing his cum in, before pushing his finger inside. Sasuke gasps from the discomfort. Naruto keeps pushing in till his knuckles brush against his ass. Then, he carefully pulls in and out, working his tight hole open.
When he slips his second finger inside, Sasuke has to bite his tongue to distract himself from the burn. The stretch hurts, and it's almost too much when suddenly Naruto curves his fingers, hitting a nerve that sends a jolt of pleasure through him. Sasuke's mouth falls open as he moans, drooling into the pillow
“Fuck, Sasuke. You look so good like this.” Naruto groans out and fucks his fingers into him faster, rubbing that sweet spot with every stroke.
When he pulls his fingers out, Sasuke turns his head around to watch him. Naruto's eyes are clouded with lust, and Sasuke knows his must look the same.
Without looking away, Naruto shoves his underwear down, finally letting his cock spring free. It's true Sasuke has seen his dick before but not like this. It's rock hard. Tip glistening and flushed like it's been aching to be touched for days. It seems a lot bigger than Sasuke remembers, too.
Nervously, Sasukes says, "I don't think that's going to fit inside me.”
“It'll fit, don't worry. Come here.”
Sasuke turns fully around and sits up. Naruto reaches towards him and grabs the back of his head, yanking him forward. He shoves his thumb in Sasuke's mouth, pushing down on his tongue.
“Open up for me.” Naruto's voice drips with pent up desire.
Sasuke's confused and tries to pull away when Naruto grips the base of his dick and shoves it into his mouth. Sasuke chokes around the intrusion and pushes back on Naruto's thighs. Naruto holds his head in place, not letting up.
“Get it wet.”
He gently rubs Sasuke's cheeks, encouraging him forward. Sasuke tentatively starts to lick and suck around the head. He's never had a dick in his mouth before and doesn't really know what to do. He seems to be doing fine though when Naruto moans and thrusts into his mouth deeper. He hits the back of Sasuke's throat, fucking into his mouth faster and making him gag. His eyes start to water and he feels it mix with the saliva falling down his chin.
Naruto pulls out and shoves him down onto his back. He bends him in half till his ass is in the air. Grasping his dick, he rubs it around Sasuke's ass, shuddering from the anticipation. It feels terrifying and heavy against him. Sasuke can't imagine how it's going to fit.
Naruto lines himself up and starts to push the tip inside. Sasuke gasps from the searing pain. The mind numbing pressure makes his eyes roll back as he desperately grips at Naruto's shoulders, sinking his nails in. His inner walls clench around Naruto, causing him to grunt in pleasure and push in further.
“God, you're so tight.” Naruto says around a deep groan. Sasuke cries out in pain as he shoves forward, bottoming out inside him.
Naruto holds him still, panting as he grips each of Sasuke's cheeks, spreading him open wider. Naruto begins fucking into him desperately. With each hard pump inside, Sasuke loses a bit more coherency. His vision blurs and he feels like he can’t breathe from how full he is. It's all too much, he can't even focus on controlling the pathetic whimpers falling from his mouth.
Naruto's greedy hands explore Sasuke's body. Gripping his thighs, waist, then neck. He leans down and sucks Sasuke's nipple into his mouth before biting down around it. Sasuke lets out a needy whine and digs his nails harder into Naruto's back. He soothes the bite with a swirl of his tongue and pulls back to look down at Sasuke, so perfect underneath him.
“I never knew you could make noises like that. It's driving me insane.”
Naruto's thrusts come faster, till he’s full on fucking Sasuke with no restraint. He tightly holds onto Naruto, trying to stay present as his head falls back in pleasure. He feels like he's being split open; molded to perfectly fit around his cock.
His thrusts start to lose their rhythm before he stills and buries himself as deep as he can inside him. Sasuke can feel his dick throb and spill out, filling him up.
Naruto drops against him, panting into his shoulder. He trails little kisses across Sasuke's neck, then lifts them both into a sitting position. Sasuke tries to move away but Naruto grips his waist, holding him still.
“I'm not done. I want you to ride me.” He sits back and pulls Sasuke up onto his lap.
Naruto's dick sinks right back inside him. With the added cum, it makes the slide a lot easier. No longer does he feel the pain in his body. All that's left is a dull throb.
From this new angle, Naruto hits that sweet spot inside him perfectly. Sasuke leans back on his hands to get better balance. He bounces his hips, fucking himself hard on Naruto's dick. It feels so good. He didn't know it could feel this good. The humiliation of his sick pleasure makes Sasuke's pheromones fire up and he reaches one hand forward, wrapping it tightly around Naruto's throat. Wanting to feel like he has some sort of control. He squeezes and Naruto's eyes roll back in pleasure.
"You're so perfect, Sasuke.”
“Shut up.” He wraps his fingers around tighter.
Naruto runs his hands around Sasuke's waist and down to his ass, digging his fingers in and helping him slam himself down harder. He's pounding so far into Sasuke it feels like he's rearranging his guts.
“Look how deep I am inside you.” Naruto says with a low gasp.
Sasuke looks down and sees the bulge of Naruto's dick inside his stomach.
“Fuck.” He sobs out before cumming so hard his vision blacks out for a moment. Naruto wraps his arms around Sasuke and continues grinding against his prostate, prolonging the waves of Sasuke's orgasm.
He's crying by the time he finishes, overstimulation starting to become unbearable. He feels so fucked out and oversensitive, but Narutos thrusts just increase in fervor.
Sasuke's too dazed to do anything but whine. The aftershocks of his orgasm still rolling through him. Naruto finally stops moving, spilling out deep inside him again. Sasuke is so full of cum he can feel it leaking out down his legs, making a mess between them. Naruto sits still, just holding him and catching his breath.
Sasuke can hardly hold himself up anymore. He falls, completely pliant in Naruto's arms. Naruto slowly starts rolling his hips more. The overstimulation is bordering on painful and Sasuke can't help the quiet, desperate cry that leaves his mouth.
“Please. I can't do it anymore.”
Naruto softly lays him down and flips him over before going back inside him. The difference is barely noticeable at first, but slowly Sasuke begins to feel a swelling around the base of Naruto's cock. Fear rushes through Sasuke as he realizes what's happening.
“Naruto, stop! You can't knot me. It's too much!” There's no way Naruto's knot will fit inside him. His body wasn't built for it. It'll tear him apart.
“It won't fit.” Sasuke chokes out as the stretch to his rim begins to send him into a near panic.
He struggles and tries to pull away but Naruto grips him by his hair and uses his other hand to push him down, slamming his face down into the floor.
Despite his rough actions, his voice is gentle as he says, “You'll be okay, don't worry. I'll be careful.”
Naruto spreads his legs wider and he slips a finger in alongside his dick, helping prepare it for his knot. Sasuke's insides are being stretched further than he ever thought possible. Naruto continues pounding into him and hitting his sweet spot, making him see stars while simultaneously sending pain through him. It's so overwhelming he begins sobbing, unable to control himself.
“Please, Naruto.”
“Shh baby, you can take it.” He lets go of his grip on Sasuke's long dark hair to softly comb his fingers though it.
“You’re doing so good, Sasuke.”
“Fuck you.” He angrily chokes out around a moan.
“Do you wanna know why I've never taken an Omega during my rut?”
Sasuke can't respond. He can barely think straight. It feels like he's being ripped open.
“It's because they weren't you. You were made for me, Sasuke. I knew it from the moment I saw you.”
Naruto shoves his knot all the way inside with one last powerful thrust. Sasuke's scream gets stuck in his throat as he thrashes underneath him. He's immobilized from Naruto laying his weight on top of his back.
He moans as he cums, his cock spilling into Sasuke one last time. Leaning forward, he bites down on Sasuke's scent gland, sending pleasure shooting through him. It's the last thing he feels before black clouds his vision and he passes out.
~•~
When Sasuke wakes up again, it's the middle of the night. There's a heavy weight on his chest and he looks down to see Naruto is curled up against him. His whole body hurts and, from what he can see, is covered in bruises and bites.
What have they done? What does this mean? There's no way he can forget about this and just go back to normal. The feeling of Naruto's touch will be imprinted into his skin forever.
Sasuke shakes him in an attempt to wake him up. Naruto just groans and curls around him tighter.
“Wake up you idiot, we need to talk.”
“I'm tired. We can talk in the morning.” Naruto mumbles into his chest.
“Can you get off me? I should go back to my own tent.”
“No.”
“What do you mean no?”
Naruto sits up and leans over Sasuke, forearms on either side of his head. “You’re staying here. You're mine. You've always been mine, you just didn't know it yet.” His face breaks out into one of his blinding smiles before he dips down, locking their lips together.
Sasuke always believed himself to be strong. But here now… he's the weakest man on earth.
Wrapping his arms around Naruto's neck, he readily sinks into the kiss. Content to stay here, like this, forever.
