Work Text:
There's a low buzzing under Rin’s skin but he's oddly calm despite the situation. Maybe it hasn't settled in yet or maybe he doesn't care, either way, he feels too still. The silence in him isn't tranquil by any means because it’s more like the tension runners brave in anticipation of the starting gun. The calm before the storm. The silence before a bomb detonates.
He doesn’t contemplate the feeling for too long when he looks up at the screen as their updated rankings are shown.
1 | Rin - ¥240,000,000
1 | Isagi - ¥240,000,000
The rankings, the outcome of the game, Rin never cared much for it. What he wants is more personal, more vindictive, than what some arbitrary bids can give him. The #1 spot is what Isagi wants, but Rin knows that aiming for something like that isn't an achievement as much as it is a prison. A box you put yourself in that's no different than being known as Itoshi Sae's little brother. He'll spend the rest of his life chasing after something that was only ever going to be temporary but who is Rin to stop him. Or care.
All Rin wants is to crush his brother, destroy him just once, and make him feel the same despair he has. It's why all Rin can do is scoff at the Re Al logo next to his highest bid. As for Isagi, defeating him is less about who's team beats who's or Ego's worthless, made-up parameters on what he believes makes a top striker. In fact, if it weren't for the rule that everyone but the #1 in Blue Lock gets banned for life from the national team, then Rin wouldn't give a shit if Isagi ranks higher than him. But now he's getting close to Rin, tied with him, and Rin can't help but think back to his words earlier. What I desire the most, Isagi, is the moment I destroy you.
But at this moment, where his fingers twitch with pent-up energy that begins to ripple in every one of his muscle fibers, what he really wants is...
Rin sighs and walks over to the moron who's still hanging his head, completely oblivious to what he's just accomplished.
"Where are you looking, scrub?" Rin asks as he comes to stand by Isagi’s side, keeping his eyes trained ahead as sweat drips down his face. "Lift your head and look. Looks like the world wants to make us rivals..."
He can see out of the corner of his eye as Isagi does as he says and finally wipes that dejected look off his face, realizing that they're tied. His already huge eyes widen and he takes a step back in shock, body turning towards Rin's as he lets out a shaky breath. Isagi's lips part with the exhale, his chest contracting with momentary relief. Rin, still refusing to fully face Isagi, tracks a bead of sweat that drips from his hairline to the soft curve of his jaw.
"...It's hot," Rin finishes.
Isagi’s mind is already somewhere else, those annoying cogs that are always spinning his head coming up with something that is no doubt vomit-inducing. His face morphs into something stupidly bright and his smile is more of a smirk that shows off his teeth. When the feeling becomes too big for his body, Isagi clenches his fist, hits it over his heart, and lets out a roar that Rin can only guess is from elation.
Somewhere in the back of Rin’s mind, he knows he should care more about Isagi closing the gap between them. That Isagi scored one more goal than him, another winning goal, and got all the hype, all the attention focused on him once more. Neither of them got what they really wanted but Isagi’s the only one who made progress with these results.
Maybe he should be screaming too. Maybe his blood should be boiling and he should be lashing out in frustration, hands balled into fists and ready to grab or swing or strangle but all he can do is watch. His gaze is zoned in on Isagi, vision narrowing down until he can see every blink of Isagi’s eyes down to the blood pounding through his veins. If only he could reach out and wrap his fingers around Isagi’s neck, feel his pulse in the palm of his hand until he finds the perfect spot to sink his teeth into.
Rin blinks and cuts his eyes away from Isagi for long enough to realize his own body isn’t in the best shape. He’s used to leaving everything out on the field and then taking the time to recover with a routine he perfected years ago. Instead of feeling the familiar fatigue of lactic acid building up in his legs, it feels like there’s lead rolling around uneasily in his stomach. There’s a pounding in the back of his head that lets him know something is off. Something isn’t right.
He takes a deep breath, focusing on inhaling the hot air surrounding him but in between all the musky pheromones and the unpleasant twinge of sweat, Rin can’t help but notice that Isagi smells sweet.
*****
Rin barely gets through the post-game talk in PXG’s locker room. He sits on the bench in front of his cubby, slouched over and with a towel lying over his head to hide his face. He’s not listening to a word anyone says, let alone Loki, who might’ve been the most useless to him right after that blond contrarian and his piss-poor passes. One or two people try to talk to him before quickly giving up, by now used to how quiet he can get and how he’s not afraid of blatantly ignoring those who bother him.
“Oi, Rin,” someone calls out to him and he can vaguely match the voice to Karasu’s face. “Hurry up and change. We’re all going to eat.” He doesn’t wait for a response and Rin picks his head up to watch as his back disappears down the hallway.
The locker room is empty now and Rin’s still sitting there in his gross jersey that’s now cool with his sweat. He shucks it off, throwing it into the wash bin that’s already full of everyone else’s dirty uniforms, and makes his way into the communal showers.
It isn’t until he’s under the cold spray of water that washes away the grime of the game that Rin looks down at his own body. Littered across his arms and torso are uneven splotches of red and pink, all from blood pouring under the surface of his skin as bruises begin to form. He’s no stranger to bruises, cuts, or any number of small injuries but these ones, these specific bruises are ones he got from Isagi. From colliding with him, fighting him head-on, and keeping Isagi close enough that he could witness every little thing Rin did.
Throughout the game, Isagi kept surprising him in their personal battle to constantly one-up each other. Rin was already so hyper-focused on him, hell-bent on destroying him that his mind became filled with chants of Isagi, Isagi, Isagi.
As Rin evolved over the course of the game, Isagi was always the one right there with him.
He unlocked the key to his flow state and Isagi was the only one willing to put his life on the line with him. When Rin needed someone to give him a new impulse so he could rid himself of Sae’s phantom, Isagi was the one to break through and help him erupt. Explode. Blow his fucking mind.
Rin’s not dumb enough to not be able to acknowledge Isagi for what he is– someone incredible in his own right. He’s the type of player Rin desires to kill, to risk his life to destroy in the pursuit to raise his play to yet another higher level.
Then Isagi had gone and scored that last goal and Rin…
He should be fuming. He should be fucking furious but instead, he’s balling his hand into a fist and punching the tiled wall hard enough to sting. He glares down at the unwanted hardness between his legs, wet bangs dripping with steady streams of water as he continues to get pelted by the showerhead.
It’s all because there’s a small part of him, no matter how annoying and insignificant and primitive he finds it, that recognizes Isagi as something more than just a rival. At the end of the day, Isagi is still an omega. It bears no effect on his soccer, how he plays, or what Rin thinks of him but he’s still an omega. His smell still tickles Rin’s nose in a way no one else's does. His smaller build still draws Rin’s eyes in, knowing that his hands mold soundly around his waist.
They fit together, on and off the field. They match. They’re rivals. They’re equals. There’s mutual respect. Isagi’s worthy– he’s worthy– of Rin. Of being his mate.
He’s the strongest omega Rin will ever find and yet he’s not the only alpha Isagi’s keeping his eyes on.
They’re surrounded by alphas in Blue Lock, Isagi’s designation being in the minority by a not insignificant amount, but Rin never gave a shit because it didn’t matter. None of them are a threat and none of them are worth a second thought. Not that Rin should even care because he is here to play soccer, not fuck around and worry about bullshit like mates and omegas and nuisance alphas with shitty tattoos.
He told Isagi to keep his eyes on him. He’d given Isagi a place by his side to watch up close how he’d defeat him and ascend as the world’s best and yet all it took was a little over a month of them being separated for his gaze to wander. He had been wasting his time with irrelevant scrubs while Rin was the one devoting all his time and energy to his training, his revenge, and his obsession with only Isagi on his mind.
Rin had felt a surge of pride at being the one to split Isagi and that Shitty Rose up but that feeling only lasted so long when Isagi was still walking back with him to their locker room.
Because they’re on the same team, dumbass, a voice in his head scoffs at him.
He wasn’t leaving you, another says.
If you’re so scared, do something about it.
Claim Isagi.
Bite your omega.
Don’t be so lukewarm.
Make Isagi yours.
Isagi–
Isagi–
Isagi!!
Rin abruptly shuts the water off, now finished washing up even though he still feels dirty. He ignores the hard-on he’s still sporting, gets out of the shower, and wraps a towel around his waist. He feels even worse now. Despite letting the water run until it was ice cold, his skin is still overly warm and now there’s a newfound pounding behind his eyes.
Getting sick right now would be inconvenient but if this doesn’t go away he’ll be forced to go to the infirmary. He didn’t think he was that weak but there’s a chance he overexerted himself in the game. The first time he’d gone into his flow state, it only lasted for about five minutes at the very end of the U20 match but this time, he’d spent half the game in such an aggressive state of total immersion.
He’ll be fine. He just needs to properly cool down, get something to eat, and get some sleep before Ego inevitably hits them with some more bullshit.
Once dressed in a clean pair of Blue Lock-issued shorts and t-shirt, he makes his way to the cafeteria and almost turns and immediately walks out.
The smell that smacks him in the face the second he enters the room is so revolting he has to hold back from gagging. He isn’t new to dealing with the repulsive pheromones of other alphas but it's unnaturally pungent right now, even more so than when they’re on the field with their emotions running high and adrenaline coursing through them. With only 23 of them remaining at this point, he would’ve thought it’d be more manageable.
Rin covers the lower half of his face with one hand, trying to block the various scents from reaching his nose, as he makes a beeline toward where their meals are served. He keeps his head forward, uninterested in the chatter from who’s already here eating, groups of people forming around the cafeteria that’s now way too big for the few of them left. He grabs a tray and the standard meal he’s been getting as the #1 rank and, instead of finding an empty table to sit at, heads right back toward the doors.
Someone might have called his name. He might have brushed past someone else in his haste to get out of there. He can’t be bothered to check when the throbbing in his head intensifies and his body is wound up so tightly that he aches with the need to spring loose. He makes it out the door with his food despite it being like trying to run through quicksand.
He somehow manages to get back to his dorm in the France Stratum. He’s sure their room assignments will change by the end of the day but for now, he takes reprieve in the empty room and scarfs down his food like it’s the first thing he’s eaten in a week.
He can’t help but wonder if Isagi’s eating the same thing as him now.
Once he’s finished eating and lets his food digest, he gets up and makes his way to the training studio, hoping to claim a spot there before anyone else can. No one else ever is but with his luck, the one day he needs to be alone is the one day some lowlife will decide to test his already thin patience.
He makes his way down the empty hallway that's all cold metal enclosing around him in every direction like some kind of torture chamber. His body thrums with every step, jittery in a way that isn’t unlike how he feels in the midst of a game. Everything and yet nothing all seems to race through his head at once until he wants nothing more than to rip his own hair out. To fist a hand into his skull and crush his brain that loves to torment him.
It isn’t until the rich, ambrosial scent of omega disperses the storm cloud brewing over his head that Rin realizes he hasn’t made his way to the training studio, but has instead tracked down Isagi’s scent. The automatic door in front of him doesn’t open at his presence which leads him to believe this is Isagi’s room and, looking around the hallway that isn’t different from any other part of the Blue Lock facility, realizes he must be in the Germany Stratum.
He curses under his breath at his own stupidity but doesn’t move, not even an inch as he lingers in front of the door because, in an instant, his foul mood evaporates. Citrusy and caramelized, Isagi’s scent hits him like a shot of espresso until he’s wide awake. He should leave and he knows he should leave. Turn around right now and go back to whatever it was he was doing before but his eyes are drawn to the seam where the door meets the wall and his mind flashes with the idea of tearing it open.
With every deep inhale of Isagi’s scent he gets from what seeps out of the room, the hairs on his arms begin to stand and the heaviness that was sitting in the pit of his stomach ignites into a low burning fire. It’s thick and sweet in Rin’s nose and coats the back of his throat. He desperately wants to taste it, coax out more of it with his tongue and teeth until he gets his fill.
He hasn’t blinked in some time and it’s only when he hears voices from behind the door that Rin snaps out of his daze and backs away. He turns on his heel and jogs back in the direction he came from, all too eager to get out of there before anyone catches him. If Isagi were to open the door or walk down the hallway, coming back to his room from wherever, it would not end well for reasons his brain can’t fathom at the moment.
Rin makes it to the training studio on the second try and sets up a mat in the middle of the floor next to a towel and water bottle. He arranges his body into a seated cross-legged position on the mat that faces the wall-length mirror in front of him. Straightening his spine, he relaxes his shoulders and rests his hands on his knees with his palms up before letting his eyes fall closed.
He tries to focus on his breathing, following the sensation of cool air being taken into his lungs through his nose and slowly let out of his mouth. He can feel it in his chest, expanding and contracting as his diaphragm works to keep oxygen flowing in and carbon dioxide out. Inhale. Exhale.
All thoughts besides what he is doing at this moment fall away. The game today doesn’t matter anymore. What will happen tomorrow as they start training for the U20 World Cup isn’t important right now. Isagi and his infuriating attitude and annoying voice and striking smile after he scores a goal aren’t worth his energy.
Inhale.
It wasn’t long ago that Isagi used to interrupt all of his yoga sessions, clumsily copying Rin in hopes that it’d help him catch up to Rin faster. He wonders if Isagi’s kept up the routine since they’ve been separated, if those tight hips he used to complain about got any looser. Whether or not he’s gotten any more flexible, the lean muscles under his soft, plush skin contorting in any way Rin would position him… pull and push him… bend him…
Exhale.
Shit. His attention has already started to wander and what should be a practice in mindfulness only has him grunting as his thoughts are disturbed by a blue-eyed demon.
He doesn’t know how long he’s been sitting here but it hasn’t been long enough for him to feel as clammy and warm as he does. All he’s done so far is a breathing exercise and there’s already sweat gathering at his hairline and a flush to his complexion. In the stillness of the studio, he spares the few movements it takes for him to pull his shirt over his head and toss it off to the side without even looking to see where it lands.
Inhale. Exhale.
He takes more breaths, these ones deeper but more unstable, become increasingly erratic as rational thought begins to escape him. Heat and desire coil tightly in his abdomen and he grinds his teeth, feeling the pointy ends of his canines scrape against his gums. His imagination conjures up blurry visions of bodies intertwined, limbs tangled up in each other, pressing, pulling, rocking, forcing until saliva begins to pool in his mouth.
Inhale–
Rin smells it before he sees it.
He doesn’t open his eyes completely but he peeks them open just enough that he can watch through the mirror as the automatic door slides open to reveal the bane of his existence and the heart driving his obsession.
“Rin!” Isagi shouts cheerfully the moment he spots Rin’s lone figure, his face brightening like he’s stepped out from the shadows and into the sunshine. “I knew I’d find you here. You’re so…” Isagi's voice trails off as he steps past the threshold and enters the room.
Or at least he tries to enter because the moment he takes one step inside, he halts, wobbling on his legs as if he’s smacked face-first into some invisible barrier. The smile is wiped from his face as he stares at the back of Rin’s head and slaps a hand over his mouth in a poor attempt to cover up the whine that slips between his lips.
Three things become apparent to Rin at that moment.
The first is that he’s a fucking idiot for only just now realizing that he’s in rut. He should’ve noticed the moment he was still on the field and looking at Isagi like he wanted to tear the meat off his bones that he was in pre-rut. Then again, maybe he shouldn't be so shocked when he remembers how he gets during his ruts– no logic, no wasted movements or thoughts. It’s all instinct based on what feels best, what his senses tell him, and what gets his nerves fired up the most.
It’s because of how intense his rut is that Rin shouldn’t even be getting it right now. Ego has all of them contraceptives and suppressants, an admittedly smart move when shoving a bunch of hormone-filled teenagers into one building for months on end. Even without that, his parents had him put on rut suppressants the second they realized how bad it was and since then he’s only gone through his rut cycle when necessary. He’s never had a problem with his medication before, it’s never failed him, and he’s never felt like anything was off until today. There’s only one thing he can think of that’s changed.
The second thing he notices is that Isagi can also tell he’s in rut. It’s why he stumbles, his face flushes with heat, and Rin can hear the sharp inhale he takes as he gulps down more of Rin’s potent pheromones. He hasn’t moved from his spot in the doorway and through his lidded eyes, Rin can see his annoying habit of overthinking every little thing making the wheels in his brain work overtime. Rin has a guess as to what’s going on in his head because if he found Rin’s pheromones repulsive, he’d have sprinted away with his tail tucked between his legs long ago.
The third, he determines, is that Isagi Yoichi will be sitting on his knot before the day is over.
At the mere thought, a wolfish hunger floods Rin, making his shorts uncomfortable, too tight and restrictive. The first cracks in his calm facade begin to appear and as much as he wants to pounce, he knows Isagi is not the prey to underestimate. Acting like a naive little pup who got his rut triggered because he saw a pretty omega won’t do him any favors.
It’s not even like Isagi did anything in particular. He didn’t shower Rin in his scent to tempt him and Isagi has challenged him time and time again without it turning him into a knot-headed idiot hellbent on proving his dominance. The little upstart has still managed to nullify his medication, the alpha in him wanting something he hasn’t felt before. It’s not a need to beat Isagi down or control him but a need to possess. His alpha wants this omega so badly it’s willing to hijack his body to produce a rut that will give him the prowess, mental focus, and heightened capabilities to take his desired mate and claim him permanently.
Once again, Isagi has ruined something in him and he will make him pay for it.
“Are you okay?” Isagi asks as he forces the hand covering his nose to go back to hanging by his side. Concern laces his voice and it plucks at each and every one of Rin’s nerves.
A bead of sweat trails slowly down the side of his face from the effort it’s taking to stay still. Rin’s no longer worried about meditating, not when his entire world has just narrowed down to one oblivious dumbass. In a way, his failed attempt at meditating did work because now his head is clear. Clean. Pure, even, but only in the sense that all those things are synonymous with Isagi and now his consciousness is too.
Rin’s eyes have been glued to Isagi, tracking him through the mirror, since arrived but from Isagi’s point of view it must look like Rin’s still focused on his meditation and barely giving Isagi the time of day. It has Isagi foolishly walking further into the room, the door closing behind him with a swish and sealing his fate.
“Rin?” Isagi tries again as he pads across the floor and holy fuck, Isagi may seem like he’s calm but as he gets closer to him Rin can tell he’s not at all unaffected by Rin’s sudden rut. His scent has somehow gotten worse, thickening until it feels like Rin’s swallowing down spoonfuls of honey. Whether he’s doing it consciously or not, Isagi releases wave after wave of pheromones that scream a response to Rin’s. I’ll take care of you, his scent seems to say, curling around him gently like a soft caress. I’m ready for you.
Rin holds his breath. Just a bit closer…
Isagi’s feet plant themselves on the mat in front of Rin and he bends at the waist, reaching a hand out like he’s about to check Rin’s temperature. “Hey, if you’re not feeling well you should go– woah!!”
Isagi lets out a yelp as Rin’s eye snaps open and with lightning quick reflexes, he grabs Isagi’s wrist and yanks him down. Isagi falls onto his lap, his free hand bracing himself on Rin’s shoulder while his legs tangle with Rin’s. Once his lap is full of the heavy weight of his omega, strong arms wrapping tightly around his middle to keep him in place, Rin buries his face in the crook of Isagi’s neck.
This kind of touch is unfamiliar to him and when Isagi doesn’t bother to push him away, only relaxing in Rin’s hold and letting his full weight settle on him, Rin can’t help but purr in approval. He licks a stripe up Isagi’s neck, tasting that citrusy scent on his tongue and reveling in the way Isagi shudders above him. His eyes roll back back from the heavenly taste and his mouth drops open, teeth scraping against the delicate skin of Isagi’s neck.
“Did you miss me that much?” Isagi asks, breaking Rin’s single-minded focus on the patch of skin right below his jaw.
Rin closes his mouth and leans back until he sees Isagi’s soft smile and the twinkle of amusement in his eyes. Did he miss Isagi? He can’t say he did when there was a part of him that was avoiding Isagi, not wanting to meet him again until he improved and was sure he could crush him, face him head-on on the field. Then again, the way Isagi’s thighs straddle his hips has him thinking he will have something to miss dearly going forward.
“You do know you're in rut right now, right?” Isagi tries asking another question when Rin’s response to the first is to stare at him. He tilts his head curiously, eyes darting back and forth between Rin’s as he chuckles. “Are you even aware of what you’re doing?”
The insinuation that Rin’s too dumb to be aware of his own actions pisses him off.
“Shut up,” Rin bites out, his voice sounding strained like he’s in desperate need of something to gulp down and relieve his thirst. He already knows what would give him the satisfaction he’s looking for, it’s sitting in his lap, already dripping for him. As he moves his hands to grip either side of Isagi’s waist, feeling how small yet powerful he is in his grasp, he knows that all it would take is for him to flip Isagi over and bend him in half until he's spread open, begging and twitching and–
“Holy shit, Rin, pack it in,” Isagi groans as he bows his head to hide his face but Rin can still see the way the tips of his ears turn red. “You don’t need to suffocate me, I’m right here.” He shifts uncomfortably in Rin’s lap, no doubt wet and slick as he reacts to the spike in Rin’s pheromones.
Rin’s fingers dig into Isagi’s waist and a low growl reverberates in his chest at the sensation of Isagi rocking against his hard-on. “Hah?” he grunts and nips at the flushed skin of Isagi’s ear, only halfway comprehending what he’s saying. “The fuck are you going on about?”
“I could smell you outside my room earlier,” Isagi admits, shyly hunching his shoulders up to block Rin from reaching his neck with his lips again. Rin watches with hawk eyes as Isagi finds his courage once more and lifts his head to reveal his dilated pupils, the pretty blue of his irises almost entirely swallowed up. The effect he seems to have on Isagi makes Rin shiver, excitement bubbling to the surface at the thought of what he does to the omega.
“I know you want me, Rin,” Isagi says, his chest rising and falling in quick pants now while his hands trail up Rin’s shoulders to cradle his face. “You marked your scent there like you wanted me to come find you.”
What a fool. Rin wasn’t leaving little clues for him to follow like some children’s game, he was dropping a lure to entice his next meal to fall into his trap. Now here he is, right where Rin wants him and exuding a scent so heavy with arousal that it mixes with Rin’s until they become indistinguishable from each other. It forms something so addictive, better than anything he could've imagined, his own crisp earthy tones combining with Isagi’s sweet scent that reminds him of days spent by the sea eating ice cream.
“Unless this is just your rut talking…” Isagi continues, his voice trailing off at the end to make him sound uncertain, unsure, even with everything that’s happened to lead them to their current positions.
This is a stupid thing to say. Rin feels the urge to devour Isagi at all hours of every day regardless of his rut. It’s a simmering lust that’s always in the back of his mind. A pacing animal merely waiting to be let out of its cage.
Rin’s skin burns from Isagi's touch and his breaths come deep and ragged. Heat twists in his core until he’s using his grip on Isagi to make him rock against his groin and give him temporary relief from the unbearable pressure between his legs.
“You’ve got bigger things to worry about,” Rin groans as he shamelessly builds up a rhythm of grinding Isagi’s ass into his lap.
“Like what?” Isagi breathes, following Rin’s pace and moving his hips himself. He leans more into Rin’s chest, their faces only inches apart as they lock eyes.
“Like how you’re going to fix this mess you made.” He wants to curse at how hungry he sounds, like a dog snapping and snarling as it resource guards its food.
“Shouldn’t that be self-explanatory?” Isagi’s hand travels from his cheek to the back of his head, fingers carding through his hair until he’s gripping his strands in a tight fist and holding his head in place. It should bother him, should make him want to flip their positions and tower over Isagi but he’s stuck. A part of him wants to see what Isagi will do, how a strong omega like him will act with a rutting alpha at his fingertips, and the other part of him likes the view too much. Looking up at Isagi, the studio’s fluorescent light paints a halo around him that Rin can’t help but marvel at.
“You’ve been hard since I walked into the room,” Isagi teases with a quirk of his brow. He yanks Rin’s head back with a quick jolt that sends pain radiating through his scalp and leans in closer to speak his next words right against Rin’s lips. “Be honest Rin, when you said you were giving me a special seat, you meant on your knot, right?” He sneers. “You really are a pervert.”
“Don’t get so cocky,” Rin hisses into Isagi’s mouth, “otherwise I'll rearrange your guts.” Another wave of arousal shoots through him, his stomach flipping and his dick throbs because, fuck, he needs… he needs–
Isagi smirks. “As if I couldn’t handle it.” He lets go of Rin’s hair and instead pries off one of the hands glued to his waist. Rin’s so preoccupied with staring at how small Isagi’s hands are compared to his that he doesn’t notice what’s happening at first. Isagi maneuvers Rin's hand to rest against his stomach, palm laid flat and splayed over his t-shirt, his fingers resting just above his navel. Once he’s pleased with his work, he holds his own palm over Rin’s hand to keep it in place and looks back up at Rin’s face, their eyes meeting once more. With a cheeky grin, he presses their hands more firmly into his stomach and lilts, “I bet you’d fill me up until here.”
The last of Rin’s sanity shatters and he crashes his lips against Isagi’s in a searing kiss. Warm, chapped lips part beneath his with a gasp and Rin instantly swallows it down with a groan. Isagi’s only stunned for a moment when he starts moving with Rin, letting Rin’s tongue sweep over his upper lip and delve inside to run along his teeth.
Their hands all move at once, fumbling and frantic as Isagi wraps his arms around his shoulder and Rin moves his hands across the small span of Isagi's back. Isagi keeps letting out little high-pitched noises that set off Rin’s prey drive, making his kisses turn violent as he bites Isagi’s lips and all but shoves his tongue down his throat in an attempt to consume him whole.
It’s a thrill to Rin and his alpha both that Isagi doesn’t just melt into him but tries to push back, meeting Rin with his own inexperienced tongue in a challenge. Everything between them is a constant push and pull, and every cell in Rin’s body flares with the need to finally possess this fucking revoltingly arrogant omega that haunts his every waking moment.
He keeps licking into Isagi’s mouth, their tongues tangling as they taste each other, chasing after the fervor that keeps them connected. Isagi’s hips move in erratic and sloppy little thrusts, grinding his clothed cock against Rin’s abdomen and granting some friction to ease the pain of how turned on they are. Their scents become a thick cocktail of potent filth as Isagi mindlessly rubs his wrists along the back of his neck, scent marking Rin like he’s the one who needs to stake his claim over the other.
Rin gets so lost in the moment that he doesn’t realize Isagi’s pushed him back until his shoulders hit the yoga mat and Isagi’s entire body weight is snugly pinned on top of him. Not an inch of space exists between them and every point of contact has his alpha clawing at his insides in a complete frenzy, willing to do anything and everything to get what it wants. Rin can’t take it anymore either, he needs Isagi now, needs him knotted and stuffed full and marked with his teeth, his tongue, his handprints, his seed, his everything.
The second Rin’s hands slip underneath Isagi’s shirt, groping at his soft skin and trying to undress him, is the moment Isagi wakes back up. He rips his head back, separating their mouths with a loud parting smack as a string of saliva that connects them breaks and drips down Rin’s chin. As he sits up, his nails scratch down Rin’s chest and abs, leaving behind a trail of goosebumps until he’s looking down at Rin with glassy eyes and shiny red-bitten lips.
Isagi grips the hem of his shirt but Rin’s too blinded by the stars forming behind his eye when their erections harshly rub together to notice the shift that occurs in Isagi.
His mistake lies in letting his hazy rut-infused brain lull him into a false sense of security which has him thinking Isagi is all his just because he’s in his arms. He watches as Isagi pulls his top up and over his head, mesmerized by the scattering of bruises on his torso that match the ones on his own, but the second it’s off, Rin gets smacked in the face with the pheromone-drenched shirt. In the second that Rin’s vision is obscured, Isagi jumps off his lap and sprints out the door with a smug laugh meant to taunt Rin.
In a flash, Rin is chasing after him.
The headstart Isagi got for himself is enough for him to get out of reach but not enough to shake Rin off his trail. Even if Rin lost sight of him, his smell would be all Rin needs to track him down but as it stands, he still has that clear sight of that lithe back and waist his hands were just wrapped around. They’re both only clad in a pair of athletic shorts as they dash down the hall, bare feet slapping against the floor and hair sweeping back out of their faces. Rin can already feel the burn in his tight muscles, a tightness in his thighs and calves that gets his heart pumping against his rib cage and endorphins spiking through him.
Isagi doesn’t bother to look over his shoulder and see where Rin is, not daring to lose any momentum, and for good reason when Rin is closing the gap between them. Even as they pass a group of people lingering in the hall with towels around their necks from their baths, Isagi only swiftly dodges them and makes a turn down the next corridor. Rin almost bulldozes over one of them as they all watch Isagi disappear, unaware that the real threat is Rin and his determination to stop at nothing until he gets what he wants. They might be shouting after them but Rin doesn’t care when catching Isagi, trapping him, and pinning him down until he can sink his teeth permanently into the supple flesh of his neck is an all-consuming thought.
Rin can’t even get mad at Isagi for running because this is what he really needs. This feeds into something more primal that lives within him, the more feral side of his nature as an alpha that wants to give chase like they would in the wild, to prove himself as someone worthy of submitting to. Isagi falling into him so easily is boring, it does nothing to excite either of them but like this, he can let out all that suppressed energy, all his frustration, and that beast caged inside of him is finally set free. Who knew it was Isagi who held the key?
Isagi takes another sharp turn down an opening to their left, his hand pushing off the opposite wall to give him momentum to shoot down the hallway and in that split second, Rin can see his face. He’s got sweat dripping down his temple and there’s a lively flush to his cheeks but more than that, there’s a manic smile on his face. It’s the same one he’d worn earlier after attaining that top spot next to Rin. In his deranged mind, he’s probably thrilled that for once, Rin is the one chasing after him. Too bad it’ll have to be so short-lived.
The exhilaration of hunting his omega down has drool spilling from his mouth and for the second time that day, he can feel himself entering that heightened state of flow. It’s not the exact same as when he’s on the field because the goal here is different. It’s a different sort of savagery, a vicious craving, an intense impulse that has his bloodlust turning into pure, ardent lust.
Rin can feel every beat of his heart, how each chamber pumps his blood, how it flows into his arteries and pounds loudly in his ears. Even as he kicks it up a notch, his body is oddly relaxed and before he knows it, his tongue is lolling out of his mouth. This is a challenge he can throw all of himself into and his hindbrain takes over without any more conscious thoughts.
It feels fucking incredible.
He’s never letting Isagi go.
But first, he has to capture him. He already knows every little thing about Isagi when it comes to his parameters as an athlete. While his brain and mentality are unmatched, his physical specs have never once beaten Rin’s. Isagi’s top speed and acceleration are average at best amongst the other Blue Lockers. His strength comes in having better stamina and knowing when to pace himself, meaning he’s smart about choosing when to conserve energy versus full-out sprinting. Unlike on the field, Isagi had no choice but to go for a full-blown sprint from the beginning. Rin’s already closed the gap between them significantly and with his longer legs, Isagi has about a minute until Rin can get his hands on him.
One minute until Isagi will be forced to think if he isn’t already. One minute until whatever idea he’s concocted will go into motion. This is exactly what Rin wants, to force Isagi to bring forth his best-laid plans and then destroy whatever vision he has in his head. Rin doesn’t need to outfox him like they’re playing a game of chess, he just needs to let his body’s instincts react for him because he doesn’t care how pretty or ugly things end as long as his knot is stuffed inside Isagi’s ass.
If Rin knows all this then Isagi knows it too which is why once Isagi makes a left down one mostly unused hallway, far away from where everyone else at this time, Rin can see his plan. Blue Lock’s facility is mostly made up of long, narrow hallways that branch off into all kinds of different rooms for their use– dormitories, dining halls, monitoring rooms, training rooms, and practice fields. Each of them leads to a dead end that would result in Isagi’s immediate loss.
In the center of this ridiculously large and high-tech building is a massive stadium with a full-size regulation field and stands to fit thousands of spectators. It’s exactly where Isagi is gunning for, a giant open space where it’ll be hard to pin him down. But it’ll also be harder for him to hide. His spatial awareness will only get him so far when it’s just the two of them.
Isagi races ahead, bursting through the double doors that lead into the locker room and knocking down a trash can that Rin swiftly jumps over, right on his heels. They pass through the locker room and out into the tunnel where Isagi rips open one last set of doors and then they’re barreling out onto the field. The floodlights aren’t on but it’s still early in the evening where the sun hasn’t gone all the way down yet. A decent amount of daylight is left so Rin can still see everything, see Isagi, clearly.
The outside air is fresh and cool but does nothing to pacify the delirious state Rin is in as they exit the tunnel at midfield. Isagi darts to the right in a straight shot toward the penalty area but whatever he’s gunning for, they’ll never find out as Rin closes in on him.
He doesn’t grab Isagi or pull him back but crashes into him, tackling him to the ground. They roll around, a mess of sweaty limbs as Isagi flails and kicks and scratches at Rin, desperate to escape his hold. Rin wrestles him into the grass, straddling one of Isagi’s thighs while the other hooks around his waist, Isagi kicking his heel into Rin’s back. With one rough shove, Rin pushes Isagi by the shoulder to the ground with a rough thud that knocks the wind out of him and pins him there with a hand around his throat. He doesn’t squeeze or apply any pressure, just lets it sit there as a reminder. A warning.
“Fuck!” Isagi wheezes out of breath and wraps both his hands around Rin’s wrist, trying to pry it off his neck. “That hurt, you freak.” He claws at Rin and weakly squirms, low on energy but still fighting, still refusing to back down.
“Where the fuck do you think you’re going?” Rin huffs out as he catches his breath.
Between his loud pants, Isagi meets Rin’s glare head-on. “C-Can’t let just any– hah– horny alpha get their hands on me.”
The mere mention of another alpha has Rin’s temper flaring and he lets out a snarl. The idea of someone else being in his place, having their hands on Isagi, and bearing down on him like he is makes him want to rampage. This Isagi, laid on his back with his hair fanning out around his face, a flush creeping up his chest to his neck, and bottom lip swollen from when Rin was biting it earlier, is all his. Just as the world now knows they’re rivals, they will also know that Isagi belongs to him without question.
Isagi lets out a breathy laugh and the soft, lyrical sound of it makes Rin perk up like a dog who’s heard the word treat. Isagi pushes his hips up into Rin, arching his black off the ground in an attempt to jostle Rin off of him. “Took you long enough to catch me.”
Rin only pushes his hips back into Isagi, nudging his erection against the crook of his groin, and a white-hot shot of pleasure radiates up his spine. His underwear is sticky now from the amount of pre-cum he’s releasing, his body telling him he’s more than ready and the feel of Isagi’s own hardness pressing into his thigh doesn’t escape him. He stares down at Isagi, fixated on his face, and grinds down more to chase the euphoric feeling, hips working against their sweat-damp shorts.
The full brunt of his rut hits him as he loses himself in the feeling and heat of Isagi’s body wriggling underneath him. He sees it more than feels it as a string of drool dribbles from his mouth and lands on Isagi’s cheek. Isagi’s nose crinkles at the feeling but Rin doesn’t pay it any mind when he leans down and licks it up. He doesn’t stop there and keeps licking at Isagi’s face, tasting his sweat and scent like it’s a compulsion.
It takes Rin longer than usual to process what Isagi has said, to remember that he said anything in the first place. Once the words reach his brain like they were spoken to him underwater, he gives his delayed response as he mouths at Isagi’s jaw. “I like to play with my food.”
“You gonna devour me?” Isagi teases, whispering the words lowly into Rin’s ear as he bites at Isagi’s neck. “Go ahead, then.” Then Isagi goes limp. He stops pushing against Rin. His arms drop to the ground by his head and the leg that was hooked around Rin’s waist also falls. He turns his head to the side, neck twisting in Rin’s loose grasp to show off the expanse of his unmarked neck like he’s offering it to Rin.
Rin might be out of his mind but his rut hasn’t rendered his brain useless.
The last thing he needs is Isagi’s fucking permission to do what he going to do anyway. He’s not the one in control here. This tactic of playing dead won’t work on him, he’s not going to lower his guard only for Isagi to sprint off again. Rin doesn’t make a move, he doesn’t loosen his hold on Isagi even a centimeter, only pulls back far enough to let Isagi see his face and how much he’s not falling for his bullshit.
“Don’t you at least wanna move somewhere more… private?”
He’s stalling now. Rin realizes there was another advantage he was trying to gain when leading him out here. It’s true that being out in the open like this makes Rin uneasy when what he really wants is to burrow away somewhere safe with Isagi. There’s no cover or seclusion out here, it’s too vulnerable, not snug enough and it'll be harder to protect them if needed.
Maybe he’d give more a shit about those things if his dick didn’t hurt so much from how badly he needs to pop his knot.
Isagi must sense it too, another shift that happens in Rin because the second Rin’s about to start gnawing on him again, Isagi starts fighting back once more. He slaps a hand over Rin’s face in an effort to push him away and Rin’s had enough of his pointless defiance. In one swift move, Rin overpowers Isagi by capturing both his wrists in one hand and pinning them above his head. With his free hand, he pushes Isagi’s legs around until he’s slotted between them and there’s no chance of him being kicked.
Out in the open like this, their pheromones are more diluted which is why Rin leans over Isagi, letting his body weight cage him in, and lets his mouth hover above Isagi’s while flooding him with his rut scent. He watches with rapt attention as Isagi has no choice but to breathe it in, making his eyes flutter and his back arch off the ground.
“Nggh, Rin!!” Isagi whines high in his throat as he gives up all resistance and, for real this time, turns entirely pliant. He melts, responding the way he was meant to with an alpha in rut before him, limbs loose and lazy and ready to submit. Rin’s impressed he was able to last this long. He’s only heard from the news or the mouths of others, the stories of how heat and rut pheromones can make people go crazy– sometimes even crazier than those in heat or rut themselves.
None of that is needed when Rin can now so easily trail his free hand down over Isagi’s stomach until he can hook his fingers underneath both the band of his shorts and underwear, pulling them clean off in a few tugs. Fucking hell, he didn’t think it was possible but those two layers covering him were holding back so much of his scent. Isagi’s still hard and dripping slick and Rin’s eyes roll back from the pure euphoria that swims around his head.
It’s because Isagi’s now completely exposed that Rin can sense the slight shift in his scent. His nose wrinkles at the sour tinge his scent develops. If Isagi has suddenly changed his mind, Rin doesn’t think he’ll be able to stop.
Still, he slows his hand until it rests at Isagi’s hip, fingers impatiently digging into his skin. “What the fuck are you getting all worried for?” Rin hisses against Isagi’s mouth, watching the way he pinches his eyes closed and draws his brows together.
Isagi’s scent still settles the moment Rin pauses. “I just– do you know what you’re doing?”
“The fuck do I look like?”
“Umm,” Isagi peeks an eye open and looks Rin up and down, “a giant virgin…”
Isagi always did know best how to piss him off. His doubting Rin, as if he doesn’t know how to take care of his own rut, how sex works, or how to handle an obstinate omega that’s determined to die by his hand, makes his teeth grit so hard his jaw aches. Rin is the one who knows everything about Isagi. They’re the ones closest to each other, who can read each other on the field. Opposites, but in a way that’s complementary to each other, constantly pushing each other and getting each other’s way.
Another thought begins to take shape in his brain, one that has an ugly monster rearing its head. If Isagi’s so concerned about his level of experience then does that mean has experience himself? He never considered it, that some other alpha would’ve laid their disgusting, unworthy hands on his omega. When did it happen? Was it before they met? Or did someone have the gall to swipe what's his right out from under his nose? Was it a fellow Blue Lock player? One of those foreign players? Was it that fucker Isagi teamed up with? Rin will kill them. He doesn’t care, he’ll end whoever touched Isagi, destroy them, and erase them from existence–
Isagi whimpers and shrinks below him, trying to become smaller as Rin’s rancid mood permeates the air.
His anger directs itself at Isagi in a flash. “Who the fuck else have you been messing around with?” he demands, his words sharp and biting with the accusation.
“What? No one!” He tries to twist his hands in Rin’s grasp, and taking it as a sign he wants to escape, Rin clamps down hard enough to bruise him and bares his teeth. “Oh my god, Rin. Chill out, you beast. You’re my first, that’s why it's scary!”
Rin eases up at the admission but knows he won’t be able to let it go until he’s fully satisfied. He still has a point to prove so the hand curled around Isagi’s hip snakes downward until he can feel the wetness between Isagi’s legs. His hand eases across his skin thanks to the slick gushing out of him, his fingers gathering up the slippery liquid at his rim before pushing two fingers into Isagi’s soaking wet hole without any warning.
Isagi keens at the sudden feeling of being penetrated and splays his legs out to give Rin better access. For someone who’s been complaining and stalling so much, he feels awfully ready to take Rin.
It’s the strangest thing, having his fingers inside of someone, to know that no one else has ever touched Isagi this way, besides maybe Isagi himself. His insides are so warm, the soft muscles of his inner walls squeezing around him and Rin groans at the thought of what that’ll feel like around his cock. He’s so used to all of Isagi’s hard edges and biting tongue that every new bit of him he’s learning about now is so disarming.
Like how his face has turned an alarming shade of red or the way his mouth falls open but no sound comes out. Tears are prickling in the corners of his eyes as he stares wide-eyed at Rin. His hands restrained above his head struggle in Rin’s grasp, alternating between clenching into fists and stretching out his fingers like he needs something to hold onto to steady himself. He jerks, like the last twitches of a rabbit that’s been caught between the jaws of a hungry wolf before he gives in and starts swaying his hips, trying to move against Rin’s hand.
“Rin,” Isagi moans out in what sounds like a plea for Rin to do something, anything, more than just feast his eyes on him and oh– it gives Rin such a rush to have this power over him.
That’s when Rin starts pumping his fingers in and out, feeling how Isagi clenches around him, his body pulling him in further. It takes little work for Rin to add a third finger, to reach deeper into Isagi and leave his fingerprints on every part of him. The sounds of his fingers sliding in and out are filthy, a vulgar squelching that not even Isagi’s ragged and uneven moans can hide.
The scent, holy fuck the scent, it’s like the sticky, syrupy drippings of a popsicle melting down his hand in the middle of summer. Rin’s mouth waters and more saliva dribbles from his lips as he craves for a taste straight from the source.
If Isagi’s going to be a little crybaby right now then Rin will take the next best thing. Making sure he’s not at risk of popping his knot out in the open air, Rin lets go of Isagi’s wrists, pulls his fingers from his ass, and leans up to sit back on his heels. Wrapping both hands around Isagi’s waist, he manhandles the omega, dragging him up until his back rests on Rin’s thighs and his ass is right in his line of sight.
“What are you doing now?!” Isagi shouts with clear alarm in his voice, his legs flailing as he tries to hide himself. Even when embarrassed at his most intimate parts being exposed to Rin, his hole still contracts, leaking out another glob of slick that trails from his ass down to his taint.
Rin would answer if he was still capable of using the part of his brain necessary for speech but all he can come up with now is a low warning growl that has Isagi whimpering instead. He clamps a firm and unyielding arm around Isagi’s middle, the other holding one of Isagi’s thighs out of the way, and then lowers his head to sweep his tongue through the mess of slick between his cheeks.
The smell of Isagi pales in comparison to the taste of him. As an athlete, Rin’s never even considered the idea of using any type of substance that could mess with his body or mind but Isagi’s slick is something he could get addicted to. It’s pure nectar on his taste buds, thick and honeyed without making it difficult to slide down his throat and it further fuels the blaze of desire within him. He’s dangerously tempted to spend the rest of his life as a Lotus-eater with his tongue lapping at Isagi.
He takes as much as he wants as his lips and tongue prod at Isagi’s rim, nipping and laving at the sensitive puckered skin. He’s never done anything like this before and has never been interested in the thought of doing something like this despite being a healthy teenage alpha, but he doesn’t feel any hesitancy. It might as well be second nature to him as his tongue glides over Isagi, alternating between swirling around his hole and flicking the tip inside.
Even with his inexperience that Isagi was so worried about, he seems to be enjoying the attention Rin’s giving him. He can distantly hear Isagi babbling nonsense below him, the constant stream of mewls and whines leaking past his lips only spur Rin on more. Fingernails scratch at the arm Rin has coiled Isagi’s middle to hold him in place, digging into his skin and silently pleading for more.
Isagi’s nails make little sharp pricks of pain shoot up his arm and it's exhilarating. He squeezes Isagi’s thigh and gives his hole one more broad stroke with the flat of his tongue before he dips inside, pushing past the ring of muscle that’s now loose enough to let Rin in and lap at his inner walls. He groans shamelessly as he starts fucking Isagi with his tongue, slurping up every drop of his slick with a hunger he’s never felt before.
“W-Wait,” Isagi cries out, drawing Rin’s focus back up to where his face is wet with either sweat or tears. He’s still tugging at Rin’s arms but he uses his other hand to reach above his head to rip up the grass and dig his fingers into the dirt to anchor himself. “Oh my god! I’m gonna cum!”
Rin doesn’t wait or slow down at all as he continues to bury his tongue in Isagi’s hole, slick now dripping from his chin. Isagi’s harsh pants get higher and higher in pitch, sounding so loud in the empty stadium, as he reaches his limit. Another cry of Rin’s name rings out but Rin still wants to push him further, wants to make him cry and beg even more, to taste his tears and absolutely ruin him.
Come on, come on, come on! Rin eggs him on in his mind, the alpha in him relishing every little bit of pleasure he’s prying out of his omega. Isagi’s hips buck harshly against Rin’s chest as he curls the tip of his tongue inside him and before Rin knows it, Isagi’s throwing his head back as he cums over his stomach. He keeps still as Isagi clamps down around his tongue, hole twitching from the force of his orgasm, a sensation that makes his eyes widen and dick throb.
As Isagi comes down from the high of his orgasm, Rin lowers him back to the ground and wipes the slick off his face with the back of his hand. He greedily drinks in the sight of what he’s done, the mess he’s made of Isagi from using his mouth alone. Isagi’s eyes are still closed as Rin positions himself between his limp legs and crawls up his body to linger over him.
Isagi is most likely still sensitive from his orgasm but Rin doesn’t care. Isagi isn’t the one in rut. He’s not the one who's been neglected this entire time and now it’s his turn. Isagi’s eyes finally crack open as Rin lowers his shorts enough to free his aching cock, heavy and hard and ready to breed the insufferable runt lying under him.
“Hold on,” Isagi weakly protests when Rin pushes his knees up to his chest and nudges the tip of his cock against his hole. Isagi’s hands fly up to grip Rin’s shoulders and he looks down between their bodies, eyes widening as he takes in the full sight of Rin’s naked body. “I just came!”
Rin preens slightly under the omega’s stunned gaze. He’s big, he knows that much, or at least he’s considerably bigger than Isagi. It’s not much of a competition when their secondary genders mean they’re capable of doing two very different things but if it were, he’d win.
“Shut up, you selfish asshole,” Rin grunts with a cocky roll of his hips as the head of his aching cock catches on Isagi’s rim. “I’m the one who’s mid-rut so do your fucking job and satisfy me or I’ll kill you here and now.”
“Fuck you!” Isagi takes a sharp inhale at the feeling of Rin breaching him, curling his arms around Rin’s neck to pull him down closer into a hug. They’re face to face again and Rin can clearly see the fever in his bright eyes that leer at him from beneath heavy lids. “I’m not the one who made you stick your tongue up my ass like some depraved freak,” he hisses against Rin’s mouth, provoking him.
“Keep talking while you still can,” Rin threatens and immediately thrusts all the way in, bottoming out in one push that knocks the breath out of both of them.
Rin’s vision blacks out at the overwhelming feeling of a tight heat and blissful friction that encase him. It’s so different from feeling Isagi around his fingers or tongue and a million times better than having his own rough hand jacking himself off. This wet pulsing warmth around him is something he’d never find anywhere else.
Their breaths come shallow and shaky, panting into each other’s open mouths in the silence that settles around them. They stare at each other in an oddly intimate moment where they both seem to be hit with the reality of what they’re doing.
Sex, Rin’s brain unhelpfully supplies him with. He’s having sex, rut sex, with Isagi Yoichi. His rival, the person he wants to kill the most, who occupies every corner of his mind and is the very reason they’re here right now, tumbling in the grass. Yet the surge that takes over him is the same as what he feels during a game and that adrenaline rush is unbelievable. It’s a feeling he wants to keep. It’s Isagi he wants to keep.
Isagi might actually be able to read his mind because he slides one hand from his back to cradle Rin’s face, palm burning against his cheek. Before he can say anything stupid like uttering Rin's name in the most adoring voice, Rin surges forward, erasing the millimeter of space separating them, and kisses him.
It’s all tongue and teeth, breaths huffing into each other’s mouths as Rin’s heart beats erratically in his chest. Or it might be Isagi’s heart. It’s hard to tell when they’re pressed skin to skin, so close that he’s lost track of where he ends and Isagi begins. As Isagi’s hands roam across the corded muscles of his back, fingers dipping in the strands of hair at the back of Rin’s neck and rubbing his wrists along his scent gland, their scents mix into something new that marks Isagi’s as his.
Isagi whines and wiggles his hips, legs coming up to hook around Rin’s back as he tries to rock against him, body now used to the feeling of Rin buried deep inside him. Rin responds instinctually, bracing one arm next to Isagi’s head, and then pulls out until just the head of his cock remains inside. With all the force his thighs can muster, he plunges back in until their skin slaps together and Isagi’s scratching and clawing down his back.
Rin repeats the motion, over and over, legs straining as he gets used to the irresistible sensation of fucking into Isagi. His pace steadies into something brutal that will leave bruises on both of them, lasting proof of how reckless and hungry they are.
“Oh shit, that’s– ahh!! Rin-ngh… more, feels so good! Ahhh!!” Isagi gushes on and on, unable to shut up even now, each gasp and little sigh exhaled directly into Rin’s mouth.
They’re sticking flesh to flesh, heat radiating from the smaller body plastered to him, muscles shaking as Isagi undulates with Rin. They push through the soreness in their bodies, torsos already turning red and purple with bruises from the earlier match that they got from each other. Isagi’s jaw drops when Rin hits a certain spot inside him and their eyes lock into each other with a shared look of ecstasy.
Nails dig into Rin’s sides, puncturing his skin and dragging down his back, leaving behind a burn that he hopes will leave scars. It shoots lightning up his spine and he can’t help but bite out a curse.
“Fuck, Isagi.” He punctuates it with an even rougher snap of his hips, punching the breath from Isagi until he’s throwing his head back, body pushing into Rin’s and exposing his neck for Rin to fixate on.
No longer interested in keeping up the effort and coordination it takes to kiss, Rin abandons Isagi’s lips to trail his mouth down his throat. He sucks at the sweaty skin there, not close enough to his scent gland to leave a mating bite but close enough that he’s reminded of it. He drinks in more of Isagi’s scent, becoming restless with the need to claim to him that his bites turn erratic like a rabid dog that was thrown a piece of meat. Each time his teeth bite down on his pulse, Isagi tenses around him from the pleasure like he’s trying to pull Rin in further in desperation.
An annoying but familiar tingling in his nose gives him a small warning before he feels a wetness trickle onto his upper lip. He eyes the drop of his blood that drips onto Isagi’s neck for only a beat when he licks it up and lets the metallic taste of it drive him to ram his hips harder.
Rin groans, fire pooling low in his core as his orgasm approaches and he chases that feeling, his knot getting ready to form, his alpha goading him on when he’s so close to what he needs and–
“So this is what you guys were up to,” an amused voice rings out, forcefully ripping Rin out of the little bubble he and Isagi have become wrapped up in.
Rin abruptly stoops forward, using his body to possessively cover Isagi’s as a feral growl rips from his throat, his lips pulling back in a snarl. It’s a vicious sound that doesn’t sound human to even his own ears and it makes Isagi whimper, clutch tighter to Rin, and bury his face in his neck.
Rin wraps a protective arm around Isagi’s back as he looks for the intruder. Above them, he can make out the outline of four people standing some distance away by the entrance tunnel. He can’t discern their faces when all he sees is red but he can make out the musky scent of another alpha that has a rage building up in him in preparation to attack and fight.
“Fuck off,” Rin commands in a low tone, a vein popping out of his neck. He slams his other hand on the ground by Isagi’s head, trying to block as much of him as he can from view.
Maybe he was an idiot for starting this somewhere out in the open where anyone could catch them but the unwelcome newcomers that are still just standing there must be fucking suicidal morons lacking in self-preservation. All Rin knows is that if they don’t leave and he’s forced to part from his omega, he has no reservations about painting this field with some fresh blood. In fact, it might even make claiming Isagi that much more gratifying.
“Rin,” Isagi rasps into his neck before biting his shoulder in a demand for his attention. He can’t tell if Isagi’s even realized they have company but if there’s a chance he hasn’t, Rin wants to keep it that way.
He doesn’t look down at Isagi, keeping his eyes trained on the figures in front of them, making sure they don’t dare come any closer. His hips keep moving in a slow, steady rhythm that has Isagi gasping every time he grinds into him. It calms his rut-afflicted brain to know he’s still pleasing his omega, keeping him distracted and submissive even when faced with a threat.
“Shouldn’t we make sure Isagi's okay?” another voice asks, sounding worried.
Definitely a threat. It’s like they think they can take Isagi from him. As if he can’t take care of Isagi best. As if Isagi isn’t the one who brought all this on. To demonstrate just how misguided they are, Rin bears down more of his weight on Isagi and snaps his hips forward to slam into him.
“Rin! More!” Isagi cries out, so tame and easy and perfect. He claws at Rin, begging him to go faster and entirely unaware of why he slowed down in the first place.
“Nevermind…”
Rin growls again, louder this time, as his nails dig into the dirt of the field. If telling them won’t work then he’ll force them to leave. He lets his aggravation pour out of him and into his pheromones that cloud the air with a scent foul enough to make any rival alpha gag.
“Ugh, that’s so– nobody’s taking Isagi from you, Rin. We just wanted to make sure you guys were alright.” If they’re trying to sound harmless, they’re doing a poor job of it by even having the balls to speak Isagi’s name from their disgusting mouths.
Rin narrows his eyes at them, and voice rising to a shout, bites out an unyielding, “Leave. Now.”
“Can we go? I really didn’t need to see this and his pheromones are revolting. I don’t know how Isagi stands it.”
“Uh, I guess we’ll let Ego know you’re both… occupied.”
“Bye, Rin-chan! Return Isagi in one piece, please!”
Rin tracks their movements as they back away, listening out for their footsteps leading them away once they’re out of sight. The second Rin’s confident they won’t be coming back, he slides out of Isagi, flips him onto his stomach, and rams back into him.
It was his fault that they were disturbed and now Rin plans to rectify that mistake. No more wasting time. He needs to claim Isagi and he needs to do it now.
He builds his speed back up into an unrelenting tempo, his hands on Isagi’s hips and holding him still as his cock disappears into his body with each jolt of his thighs. The tension in his shoulders doesn’t ebb and his heart beats heavily in his throat. Isagi starts rocking back in time with his thrusts, back arched like a cat and making Rin’s tongue lick at his bottom lip. The nape of Isagi’s neck is shiny with a sheen of sweat and flushed red like a target for Rin to aim for.
“Isagi,” Rin rasps out as his movements become sloppy from his orgasm swelling up once more. He falls over Isagi, sweaty chest blanketing his back and boxing him in with his arms while he shoves his face into Isagi’s neck. Citrusy sweetness coats his throat down to his lungs and his knot begins to expand, teasing the outside of Isagi’s rim, stretching him open more and more until he forces it inside.
“Ah! I-I can’t– Alpha!!” Isagi reaches out to grip Rin’s wrist as his whole body shudders. The pressure from Rin’s knot makes him scream and he constricts around him, dick spurting cum into the grass as waves of pleasure sweep across him. “Fuck!”
“Isagi,” Rin groans one more time and then his teeth, sharp and dangerous, latch onto Isagi’s scent gland and take hold of his sensitive skin. He gives a few more aborted thrusts, and the rippling heat of Isagi’s hole engulfing his cock pushes him over the edge with a choked gasp. His cum pumps into Isagi, his knot locking them together and ensuring his seed will stay inside.
Isagi writhes and Rin clamps his teeth down tighter on his neck to keep hold of him, keeping him trapped and confined, entirely under Rin’s possession. It’s a struggle to breathe but Rin doesn’t loosen up as he empties his balls in the omega, marking him inside and out.
Isagi sighs shakily as he goes lax under Rin’s rigid jaw, locked around his neck like he’s being scruffed.
Only once he’s come down from his high, rut temporarily sated now that he’s claimed and knotted Isagi, does he pull back to check on him. Isagi’s eyes are closed and his expression is one of pure bliss that makes Rin’s heart do a curious little flip in his chest.
He rolls them onto their sides and curls protectively around Isagi’s back, ready to wait out the few minutes it’ll take for his knot to go back. It won’t last long, at least until his body throws him into another frenzy of lust, but for now, he sinks into the feeling of relief that blankets him. It’s the first time he’s been able to truly relax in weeks– in months– with no tension in his body and fuzziness lingering in his mind.
Both of his arms are wrapped snugly around Isagi’s middle and he laps his tongue over the back of his neck, feeling the indents on his tongue from where his teeth were, a reminder that his mark is real and still there. He doesn’t fall asleep but enters a content daze as his knot goes down and back to normal. When he comes back to reality, Isagi’s shoulders are shaking as he tries to reel in his laughter.
“Are you purring?” he breathlessly asks and tries to eye Rin over his shoulder. “That’s cute.”
As soon as Isagi points it out, he realizes there’s a humming noise coming from deep in his throat like he physically can’t contain his contentment. He hasn’t regained the ability to speak yet so he bites Isagi’s shoulder instead.
“Ow, okay, I get it,” Isagi chuckles and wiggles in Rin’s arms, trying to turn around now that his knot is gone and they can untangle themselves. “Can we at least move somewhere else? Anywhere else?”
Rin takes his time letting go of Isagi, sitting up, and tucking himself back into his shorts. They’re both going to need baths again, now sweaty and covered in various other bodily fluids, while Rin’s already worked up his appetite.
Without Rin plastered to him, Isagi curls in on himself, trying to hide his lower half when he’s still completely naked. Spotting his shorts and underwear that he’d thrown aside earlier, Rin hands them back for Isagi to slide on.
“Thanks.” Isagi makes a face at having to put soiled clothes back on but pushes through the repulsion. “We can probably find an empty room somewhere…” He trails off as he tries to get up and finds his legs are too weak to stand that he stumbles. He lets out a nervous laugh and lowers his eyes to the ground, unable to bear the awkward silence.
Isagi fidgets on the ground and Rin can’t help but think that, ideally, he wouldn’t have to find anything. He’d already have a den setup somewhere instead of being locked in a cold metal box that’s never bothered him until this moment now that he wants somewhere comfortable to hide away with Isagi. Even if they weren’t in Blue Lock, he’s not sure where they could go. His own home isn’t an option, especially in a room he used to share with his brother. Isagi probably has a cozy nest in a bedroom wherever his home is and that doesn’t sound terrible.
Making up his mind, Rin scoops Isagi up off the ground, one arm under his knees and the other cradling around his back, and finds his voice. “We’ll go to your room,” he decides and his voice is hoarse enough that he has to cough to clear his throat.
He doesn’t actually know where Isagi’s current room is but he found himself outside his door once so he can follow his scent and find it again. Or maybe he won’t when Isagi winds his arms around Rin’s neck to anchor himself and Rin can smell the subtle changes in him. With the bite on his neck, Isagi is now his, belongs with him, and now it's stamped on his very being for everyone to see.
An insatiable yearning begins to simmer low in his stomach again and he picks up his pace, knowing it won’t be long until it starts to burn and thrash and demand to take more. Rin walks them back through the locker room and out into the maze of the Blue Lock facility only to stop at the sight of someone waiting for them at the end of the hall.
It’s the second time that they’ve been disturbed and it ticks Rin off that now of all times, when he’s in rut, is when people want to keep fucking with him. The new presence makes Isagi stiffen in his arms, and whether it’s his need to guard his newly claimed omega or something else, he clutches Isagi closer to his chest.
“Oh my god,” Isagi moans for only Rin to hear as he ducks his head to hide his face in his shoulder. “The cameras…”
At that, Rin finally registers who is waiting for them and pieces together what Isagi already has. Blue Lock is covered top to bottom with various cameras so everything they just did was more than likely recorded somewhere and played on a television screen in whatever monitoring room Ego hides away in.
Even if they were spared from unknowingly creating some fucked up sex tape, the idiots who walked in on them earlier have surely blabbed to everyone about what they saw. Not that Rin cares, he’s never concerned himself with useless emotions like shame before. It might actually be of use to him for it to spread around that Isagi Yoichi is taken indefinitely.
Thinking he’s been ambushed, adrenaline courses through him in a momentary panic but once it wanes, he takes in Anri with her pristine pencil skirt, clipboard in hand, and a wry smile on her face like she’d rather be anywhere else but here.
“Well then,” she starts, tucking a strand of hair behind her ear with a long-suffering sigh. She’s not quite able to meet their eyes but Rin’s not interested in niceties anyway and lets his gaze fall back to Isagi. “Please head to Wing 3. The rooms and cafeteria are fully stocked with everything you’ll need while you… sort yourselves out. Everyone else has been consolidated to Wing 1 to begin training for the U20 World Cup. Join us when you’re done.”
Rin doesn’t need to be told twice. Without another word, he turns on his heel and heads toward Wing 3, the section of Blue Lock that doubled as England’s Stratum for the NEL.
“You can put me down now,” Isagi says after a few quiet moments when it becomes apparent that Rin isn’t going to say anything. He can feel the cocky energy radiating off of Isagi as he stares at the side of his face and then licks his thumb to wipe away the dried blood from under Rin’s nose.
“If you didn’t have such a weak physique in the first place, I wouldn’t have had to pick you up. What trash.” There’s not a chance in hell Rin is letting go of him.
Isagi huffs, muttering something about Rin having a foul mouth, and then says, “Fine. I’ve been wanting to talk to you since the game ended anyway so I guess this works too.” He cards his fingers through the layers of hair at the back of Rin’s head and it’s like now that he’s been given permission, he can’t stop touching Rin and rubbing his scent on him. “Although I didn’t think you’d immediately claim me, rut or not.”
Isagi raises an accusatory brow but Rin doesn’t care. He wasn’t thinking about what he was or wasn’t going to do, all he needed was that possessive drive furling in his chest, making him want to isolate Isagi and monopolize him. He knows what he’s feeling isn’t abnormal for a rutting alpha but to feel it to this degree and this incessantly is monstrous. He doesn’t care to keep it in check.
They aren’t friends. They aren’t partners. Even when they’re donning the same uniform the term teammates is too buddy-buddy for him. The idea of discussing things like ruts and mates or having to ask Isagi for anything makes him want to throw up and yet…
There’s something innate in him, something that lives deep in the marrow of bones that he recognizes also lives in Isagi. He’s never cared for much besides his brother, besides soccer, but Isagi’s lit a fire in him and now he’ll keep Isagi close, be the closest to Isagi, and let that oppressive heat Isagi sparked in him keep them warm.
So they aren’t friends. They aren’t partners. Hell, they’ll never even be something as insipid as boyfriends but they will be rivals. They are mates.
“You just couldn’t help yourself, could you?” Isagi asks with a feigned sigh and it starts to piss Rin off how cheery he is being about this. “You really did miss me, didn’t you? You could’ve visited me at any time, you know. And you usually take such good care of your body, too, so to suddenly go into rut is odd. Now we’re mates, which is permanent by the way so–oh! I’ll have to tell my parents. It’s a good thing I’m on birth control.”
Rin rolls his eyes as they enter Wing 3 and he heads for where the dormitories are located on each floor. He almost forgot how annoying Isagi is even when off the field. “Shut up.”
He knows he’s not in his right mind so his ability to analyze the situation isn’t up to par but he can’t shake the niggling feeling in the back of his head that’s telling him that Isagi’s playing some angle right now. He’s acting far too innocent as if this all isn’t his fault.
Rin catches the cunning glimmer in his eyes a second too late when Isagi turns the hand in his hair into a fist, yanks his head to the side, and, bracing himself on Rin’s shoulder, sinks his sharp canines into the back of Rin’s neck.
He’s not proud of the way his legs buckle from being bitten but he quickly regains his balance. The effect of the bite is instantaneous. A shot of pain zips down his neck and radiates throughout his body like having a bucket of ice dumped over his head but it lasts for only a second when it blooms into a refreshing balm on all his senses. Isagi has shot a dose of himself into Rin’s DNA, and that mix of their pheromones that he was fixated on earlier becomes permanent.
“Now we’re even,” Isagi declares once he releases Rin’s neck and leans back to take in his expression.
Even, he says. Like being tied at number one. Like two sides of the same coin. Like alpha and omega. Made to complement each other, to push and pull. Those three little words rile Rin up all over again.
His mind fills with a barrage of images of their bodies swaying together, Isagi pushing back against him and Rin thrust into him. The way Isagi’s hips moved like he was hypnotized, how good it felt to touch his bare skin, and how easy it was for Rin to make him breathless. The sounds that leaked from Isagi were so strangely erotic that even though he has already caught him, the urge to hunt him down like a starved carnivore still remains.
Rin pushes them into the first room he sees and unceremoniously tosses Isagi onto the bed. Before Isagi can complain or make another stupid comment, Rin climbs onto the bed and looms over him.
“You did this to yourself so I don’t want to hear any bitching or moaning afterward.” It’s the only warning Rin gives him when he slots himself between Isagi’s welcoming legs and kisses him.
It’s slower this time as Rin’s rut starts gearing up to rear its full head again. Isagi’s tongue traces his own and the soothing way he licks inside Rin’s mouth makes his eyes flutter shut. He tilts his head to the side, jaw moving to mold their mouths together deeper. The once calm beating of his heart picks up as Isagi’s hands palm at his chest, groping the muscles there and digging his claws in. When the pads of his fingers reach one of the bruises on his abdomen, pressing down on the tender skin until Rin can feel it throb, he nips at Isagi’s lower lip.
Isagi hums in his mouth and squirms, melting into the bed and twisting up the sheets. He’s so warm and small under Rin, content to let Rin do as he pleases and take control of the kiss without putting up a fight. A jolt of heat hits Rin’s stomach as Isagi twitches again, this time kneeing Rin in the thigh and making him pull back, their lips parting with a soft smacking sound.
“Stop fidgeting,” Rin huffs out in annoyance.
“I can’t help it!” Isagi whines. “It’s…It’s…” He turns to hide his face from Rin, mumbling the rest of his sentence unintelligibly into the pillows.
Rin cups his jaw with one hand and forces Isagi to turn his head and face him. “Speak up.”
“I said it’s leaking…” Isagi groans and darts his eyes around the room, trying his hardest not to meet Rin’s gaze. Rin stares directly at him anyway and feasts on the thrill it gives to be the one making Isagi blush. “...your cum…” he eventually finishes.
Isagi might as well have reached into Rin’s chest and squeezed his heart himself with the way he manages to manipulate the damn organ. His mate is disgustingly cute. This might be a problem. “Don’t look at me with such a shameful face.”
Even with his self-consciousness written all over his face, Isagi still peers up at Rin and bats his eyelashes. “How should I look at you then?”
Rin knows he’s going slightly insane from his rut but it isn’t until this moment that he realizes Isagi isn’t. That Isagi is fully in his right mind and is aware of everything he’s doing and has done. Rin’s rut no doubt has influenced him to a certain extent but beyond that, Isagi knows exactly what he’s doing. From the very beginning, he’s purposefully trying to provoke and arouse Rin.
Rin’s nose wrinkles and he stiffens his grip on Isagi’s jaw, eyes flickering down to look at his inviting lips. “Do not pretend that you are some meek, pathetic little omega when I can see that vicious mind working behind your eyes.”
Isagi's lips curl up into a sneer. “What a tyrant,” he bites back and struggles to pull Rin’s hand off his face.
Fuck. He is going to enjoy wiping that look off his face. “Let me say this while I'm still lucid,” Rin warns as he crowds further into Isagi’s space to intimidate him. “You’re not leaving this room until I say you can. Try to run again and I will track you down and kill you. You can cry and beg and fight as much as you want but just know it’ll only turn me on even more.”
“Yeah, yeah,” Isagi retorts, waving him off in a patronizing manner. “Bring it on, you freak. I know that wasn’t enough for you.”
Rin growls as another spark of hunger flares up in him and he dives down to crash their mouths together again.
*****
No one bothers to hide their stares when they walk onto the training field six days later– four days for Rin’s rut to subside, one day for Rin to rest, and another day after that for Isagi to recover. All conversations and drills abruptly halt as they turn to look and Rin can hear Isagi’s mind going a mile a minute as he tries to hold his head high.
Bachira is the one to break the awkward silence as he bounds up to Isagi and jumps on his back. “Isagi! I wasn’t sure we were ever going to see you again. I was betting on Rin locking you up forever.”
Rin’s rut may be over but he’s still on edge so someone touching Isagi, regardless of their secondary gender, has him resisting the urge to lash out. He still rips Bachira off his mate by the collar and throws him to the ground.
Rin ignores the look Isagi gives him but still steps toward him, plastering his chest to Isagi’s back. Everyone else starts to surround them and Rin sweeps a look around the room, frowning when they act like his tossing Bachira wasn't enough of a warning to back off. This was a bad idea. He wants to throw Isagi over his shoulder and march back to the safety of the nest Isagi had built for them over the past week.
Bachira pops back up like nothing happened and continues to rub himself all over Isagi, giving Rin a cheeky smile over Isagi’s shoulder as they immediately dive into a conversation he doesn't care to listen to when he's spent the last few days having his ear talked off.
“Were you mauled? The hell?” someone asks and gestures at Isagi’s neck.
“It was kinda like watching two animals go at it...”
The added noise from these insignificant extras that Isagi always lets flock around him is all it takes to have Rin’s eye twitching. Better than just retreating to their nest, he should chain Isagi to it and never let him leave.
Rin's nose starts to burn from a repugnant smell and before he can put any more thought into it, a finger jabs into his neck, eliciting a sharp throb as it presses into one of the marks Isagi left on him as a heavy weight falls across his shoulders.
He doesn't have to look to know that a pesky insect has thrown an arm over his shoulders with a stupid look on his already idiotic face. “Rin-Rin’s not faring any better. Kitty got claws, eh?”
The longer Rin’s rut went on and the more rounds they went, the bolder Isagi got. Despite Rin’s warnings and threats, most of their sex ended up as a wrestling match with Isagi forcing Rin to pin him down and get out all his bottled-up desires. Even now, as Isagi prattles away to Bachira, Rin’s scent– now his and Isagi’s scent– seeps out of him as if to stake a territorial claim over Isagi and show off that he was the one Isagi submitted to and now bears his mark.
That new scent that wraps around him like a comforting hug is tainted with that antennae bastard’s shit smell. He’s less than a second away from throwing his fist to get him to back off when another hand digs into his arm and pulls him from Shidou’s hold.
“Knock it off,” Isagi warns with a stern voice and the intimidating face he tries to give Shidou only makes him laugh.
“Don’t worry, Loverboy,” Shidou puts his hands up with a shit-eating grin, palms out in a placating manner, “the only one who wants him is you.”
Rin looks down at the death grip Isagi has on his arm, nails sinking into him hard enough that he knows he’d find indents on his bare skin if he were to take his training suit off. There’s a jealous fervor in his eyes that Rin is all too familiar with and when Rin senses their scent pouring out in a thick cloud around them, he knows it’s not his own doing this time. All he can do is squint at Isagi and the blatant, obstinate claim he’s making over him in front of another alpha.
Once Rin begins to hear a low rumbling coming from Isagi, his eyes still trained on Shidou, he grips the back of Isagi’s neck and squeezes his scent mark where his bite is branded.
“What’s the point in worrying about other people?” Rin asks and narrows his eyes at Isagi, irritated that the omega seems to care so much but is still facing another alpha, eyes on someone other than him. “You should just look at me.”
Isagi snaps out of whatever posturing he’s trying to accomplish and scratches his cheek sheepishly as he looks up at Rin. “It’s still annoying…”
He wants to pluck out the little sprout on top of Isagi’s head for having the audacity to be bothered by something that’s been gnawing at Rin for weeks now. If anyone should be eating his heart out, it’s Rin. All the heat that had cooled down from the past few days is ready to bounce back with the languid look Isagi gives him. The only difference is that now Rin is back in his right mind.
“Stop trying to provoke me,” Rin chides.
“Now, now,” Bachira tuts all too happily as he pats both of their arms only to immediately pull his hands back when they both snap at him. “You both got what you wanted so no fighting! Isagi was able to take advantage of your rut and Rin-chan let everyone see him fucking the daylights out of you. Win-win.”
“Everyone saw what?!” Isagi shrieks at the same time Bachira’s words register in Rin’s head.
Take advantage of your rut. Rin eyes Isagi critically as he starts flailing around a hysterically laughing Bachira with a bright red face. Did he lose to Isagi again? How much of his rut was actually an irregularity and how much of it was in the palm of Isagi’s hand this whole time? Rin got what he wanted, Isagi is his now no matter what but somehow it’s still not enough. They spent a week cooped up together and while he doesn’t regret it one bit it’s now hitting him that that’s one week he’s gone without doing any training.
Rin grits his teeth. “Hey,” he spits out, interrupting Isagi's attempts to get Bachira to shut up by grabbing his face and pulling him closer. “This doesn’t change anything. I’m still going to devour you until there’s nothing left.”
The devilish smile that unfurls across Isagi’s devastatingly alluring face tells Rin everything he needs to know. “Go ahead and try.”
