Chapter Text
The first time it happens, it’s when they’re chasing down a group of curse users that have been smuggling cursed tools and artifacts out of the country. It’s not a hard mission by any means, but Yaga-sensei tells them to be very careful about not damaging anything.
It’s a bit of a problem when they both get trapped inside one of those artifacts. A box, specially used for ensnaring people and keeping them there for a set amount of time.
“This is a piece of cake, we can just blast through it.”
“No, you can’t do that! This is one of the rarer items they have here and one of the most expensive ones! And we’re in a warehouse full of priceless artifacts! Yaga-Sensei is gonna kill us if we destroy it, and the original owners will want financial compensation for these things!”
“I don’t care, come on, do you want to be stuck here for three hours until the effects of this shit wear off?”
“I’d rather be inconvenienced for a few hours than to get this shit deducted from my salary! Not all of us have limitless funds at our disposal!”
Satoru sometimes forgets Suguru comes from a different sort of background than he does.
“I can give you allowance money if that happens. I don’t care.”
Suguru looks horrified and his instinct is to pull away, but this thing is not big enough for him to go anywhere.
“I don’t think so. I don’t want some alpha giving me allowance money, thank you very much.”
Suguru squirms and looks away, but the box is so small that they’re pressed up against each other, bodies pressed together and breathing into each other’s space. It’s very awkward.
Suguru is very stubborn.
Most omegas would jump at the opportunity to get access to the Gojo family’s money so freely offered, but Suguru gets annoyed and offended at the thought of it. He’d rather they get stuck here and be uncomfortable together than accept his help, which Satoru finds incredibly stupid.
It’s just money. He has plenty of it. If he wants to give some of it to Suguru, no one is gonna care. His parents would encourage it.
“Whatever.”
They’re so close together that is quickly becomes uncomfortable - they’re both too tall to be trapped in a space as small as this without feeling the effects of it. Satoru’s uniform sticks to his back, sweat dripping down his nape, hair sticking to his scalp. He wants to bitch about it to Suguru, but then he notices the omega beside him seems to be much worse off than him.
Suguru’s face is blotchy red, breathing heavy. Suguru’s bangs and the baby hairs that frizz out from his bun sticking to his face. Suguru’s omega collar seems to be bothering him too, because he keeps fidgeting with it, trying to move his neck as if to dislodge it. At one point, Suguru reaches toward the collar and pulls at the O ring on the front of it to move it away from his skin, and he looks anywhere other than at Satoru.
The trap quickly turns from warm to unbearably hot, and while Satoru is neither shy nor claustrophobic, he can’t deny that Suguru’s obvious discomfort is getting to him. Pressure in the center of his chest, tightness in his lungs. Short of breath.
"Hey, uh, Suguru,?" he’s trying to keep his voice level and gentle, “You alright?”.
Suguru looks up at him, deer-in-the-headlight, glowing face, glistening cheekbones. He nods and then looks away, keeps fiddling with his collar. It’s so fucking distracting though, it’s hard enough not to stare as it is when they’re in their usual circumstances, even though the thick band of leather with it’s metal O ring dangling at the center is always a point of focus, but - Suguru pulling it away from his skin like that is so enticing to him. And he’s struggling to breathe too, chest heaving against Satoru.
Satoru bites his lip looking at him, and he’s still a little upset with this whole thing, but he can’t actually stomach seeing Suguru in distress.
"Hey, Suguru? It’s just me. You can tell me if something’s wrong, you know?”
Suguru darts another look at him, brow furrowing, lips set in a grimace.
“Yeah, I’m fine, I’m fine, I’m good, it’s just - ugh .”
Suguru makes this high pitched noise, sounding so breathless.
Satoru stares at Suguru, a little offended at how his friend is fidgeting, like he’s trying to get away from Satoru despite having nowhere to go. Does Suguru think he’s gross? Does he think Satoru has some sort of alpha cooties?
“Hey, listen I don’t like this either, but you’re the one that refused to let me break us out of this bitch!”
“Satoru, oh god - Can’t you just shut up?”
Omegas are always gonna mess with any alpha’s head, so Satoru blames it on Suguru that he hasn’t noticed it sooner - the abnormal heat in the trap is coming from Suguru . He’s only noticing it now, along with the tortured look on Suguru’s face, the slackened jaw, the open-mouthed panting. All the places their bodies are touching, all places he wishes they touched too. The realization of it comes crashing onto him all at once and then he becomes hyper aware of himself too. The way his blood is racing through his body, his aching gums, the saliva pooling under his tongue. When he becomes aware of the way blood is throbbing between his legs, he grits his teeth together.
And he’s just an alpha, really - instinct gets the better of him. One of his hands goes to cup Suguru’s sweaty face, rubs his thumb over his sweaty cheekbone. Keeps the other one resting against Suguru’s slim waist.
“You’re in heat.”
Suguru’s eyes are all dark and half-lidded, and he turns to face into Satoru’s palm. Nuzzles against his pulse, the pheromone glands on Satoru’s wrist. They never touched each other so purposefully before, and now it’s making his head swim with potential..
"Yeah, I am, I - Satoru -"
God, that’s a whine. That’s a fucking omegan whine, Suguru’s whining his name. Makes him a little crazy. And Satoru doesn’t know much about omegas in heat, but it seems like Suguru’s in pain. He closes his eyes and chews on his lip and Satoru’s just staring at him stupidly.
All the pheromones in the air are making his thoughts slow.
"Why - why didn't you take your suppressants? Why didn’t you - "
Oh god, he feels like he’s aching everywhere all of a sudden, and Suguru squirms uncomfortably and his thigh presses between Satoru’s legs, friction against his cock, oh god. Fuck. He can’t really stop himself from wiggling and wanting more.
"I did," whispers Suguru, "I never miss a dose, never ever, but my CT makes my hormones unstable and sometimes my heats get triggered randomly and rapidly like this. Especially since I’m stuck here with you and your stupid alpha pheromones.”
Suguru’s breathing harder, and he’s squirming minutely against Satoru’s thighs too, their legs entwined, his hands fluttering around Satoru’s hips.
"I didn’t know, I - huh," Satoru’s a little dazed, "Must suck.”
"You bet it fucking does,” Suguru snaps, but he moans when Satoru leans closer involuntarily, nostrils flaring to sniff him, “Satoru, I don't like this. I like having control. But--"
Satoru has never fucked an omega in heat before. Hell, he’s never even scented an omega in heat before, so it makes sense that he had no idea how to clock it.
All his ruts are very carefully scheduled, and his clan brings in professionals, to deal with him when he needs it, because the heir of the Gojo Clan and the Six Eyes cannot go around knotting omegas all willy-nilly without special permission. What if he gets anyone pregnant? At least, that’s the argument that’s always been sent in his direction, and he’s never been interested enough to pursue omegas on his own.
Ruts for Satoru are a very carefully planned thing where a nurse with the demeanor and disposition of an old milkmaid meets with him in a sterile room and they make small talk before she helps manually drain his knot. He never gets the same one twice because they want to make sure he doesn’t get attached to them.
None of this is planned though, him and Suguru aren’t like that, and his cheeks burn when he looks at him. He thinks back to the rut helpers with their white gloves and minimal touch, how clean and professional everything always is, and sex with Suguru wouldn’t be like that, would it? It would be messy and heated and sweaty, mingling scents and pheromones.
He’s tugging at Suguru’s shirt without thinking about it, and sneaking his hands underneath, running his fingers over Suguru’s abdomen, thumbing at the edge where his high-waisted pants dig into his skin. Satoru’s dick is a fat throbbing line caught awkwardly in his pants. There’s a low pulse at the base of his cock already, where he'd knot up.
"Suguru – can I –"
Suguru doesn’t say anything but he nods, eyes closed, breath hitching, hips starting to push towards Satoru. The noises he makes are small and desperate and so, so cute, and Satoru can smell him even though he wears a collar over his glands and scent blockers. Suguru smells musky sweet and coiling, like hot honey dripping down overheated skin and it makes him want to lick him badly.
Suguru moans when Satoru grabs his ass, and he tries to lick over and around his omega collar just to see if he can taste him, even a little.
Satoru mouths at his neck, frustrated with his lack of access. He can only get hints of his taste, the spicy, heated sweetness of the pheromones pouring from him. Satoru buries his face in the side of Suguru’s neck, pulls down his shirt, tries to lick at the scent gland hidden under the collar, desperate for him.
"Fuck, you’re so - " he’s half out of his mind on Suguru’s scent.
"Satoru - " Suguru gasps, tugging at his hair, "Ugh - Alpha -”
Satoru pulls him more against his body, makes Suguru’s thighs spread around his hips. There’s not enough space for him to wrap his legs around Satoru, but this will do.
Suguru’s all incoherent moans and pretty whines, and Satoru likes to think of himself as pretty controlled and self-assured, but hearing this just does something to him. His cock is just aching in his pants, he’s so hard it’s painful, and he’s can feel Suguru’s little omega dick throbbing through the layers of fabric. Only makes him wilder.
It feels like the last semblances of rationality just poof away from him, and his mind is suddenly flooded with all the fantasies he struggled to keep at bay. Suguru knotted on his cock, Suguru cuming untouched, Suguru being stuffed full of his dick and bread with his pups and leaking Satoru’s cum out of his abused hole, Ugh -
Biting and breeding and knotting and rearranging Suguru’s guts into pretty little hearts and bows, really romantic shit while they’re stuck together. Fuck.
Satoru grinds their hips together, messy and impatient. He wants to undress Suguru but gets stuck in all the goddamn buttons of his highwaisted pants, so he just growls in frustration and just rips them up. His fingers brush against Suguru’s cock as he undresses him, making him whimper, but he doesn’t bother kneading it or playing with it, he’s not interested in Suguru’s cock, he’s interested in Suguru’s pretty little hole.
Both of Satoru’s hands go directly to Suguru’s ass, magnetic fucking attraction. He digs his fingers into the fat, heavy roundness of Suguru’s cheeks, feels the softness and smoothness of it as he squeezes it. God, perfect, like playing with the most delicious ball of dough - if he had the space for it, he’d bend Suguru over and bite into it.. And Suguru likes the attention too, because pushing back against Satoru’s grip, encouraging him to play with his ass more.
Suguru’s arching and twisting his body, feline and sensual, rutting himself against Satoru and spreading his sweat and the sweetness of his pheromones all over him. He’s eyes are glazed over with arousal and his mouth is all wet, slack jaw drooling on the side of his lips.
All caught up in the sweetness of heat, Suguru’s the most incredible thing he’s ever seen.
He spreads Suguru’s ass, forces his wet little hole to open up as he rubs against it. Suguru’s leaking all over himself, dripping down his thighs, staining his Jujutsu tech uniform with his slick. Satoru can’t help but press inside him, and Suguru’s body instantly surrenders to him, giving way inside. Impossibly hot and tight around his fingers, Suguru’s hole sucks him in deep, hungry for more.
Suguru mewls and ruts back against the penetration, shallow as it is. It’s just enough that Satoru’s fingers brush against his prostate, and just like that, Suguru cums all over himself. The cute little pink head of Suguru’s cock spurts semen all over his stomach.
“Oh, you came already? Just like that? You’re really gagging for it, huh?”
Suguru chokes, all embarrassed, but he can’t stop himself from pushing back against Satoru’s fingers, clearly unsatisfied. And Satoru, and he can think of is the grip of Suguru’s ass, and how that’s going to feel around his cock, and already there’s a painful throb at the base of his dick. His knot it just begging too unleashed inside of Suguru’s hole, wants to fuck him up good and well, but the problem is that’s he’s too excited for it. At this rate, he’s going to cum in his pants like a fucking loser.
“Alpha, please - ” Suguru whines between breathy little gasps, “Please, please, please - ”
His Suguru is so polite and cute. He’s got tears in his eyes and getting to be fucked. Satoru wants to eat him. He’s never wanted anyone else so badly.
He thinks back to his old biology classes, and he knows Suguru is gonna be in this state until he’s bred and knotted at least once, and Satoru’s hands shake while touching him. He needs to take a moment to cool down though, breathing deeply and trying to relax - he doesn’t want to keep Suguru in this state longer than he needs to do, but he wants to make sure he doesn’t just cum halfway in.
“Please knot me, please, please - knot me -”
"Yeah," he presses his lips gently to Suguru’s temple, tasting the sweat and heat off him. "Yeah, I’m gonna knot you, let me just - "
It’s a struggle to turn Suguru around in the tight space their in - Satoru’s the only one coherent enough to put in the work, as Suguru’s just too shaky for it, but at least he goes willingly. Trusting. Satoru presses him against the trap, Suguru’s face against the smooth wood of it. He pulls down Suguru’s pants and boxers, awkwardly letting them hang by his thighs. Satoru’s own fingers shake as he pulls down his fly and undresses. His cockhead is all swollen with blood, shiny and wet with precum.
There’s no space between them, and his cock slips between Suguru’s cheeks and his mind goes blank, pushed against him with no coordination at all. His head is a just swimming in Suguru’s heat pheromones, pushes against his ass mindlessly like maybe his cock is just doing to magically slips into the hole he’s been fantasizing about.
“Alpha, alpha, alpha - please, please, inside, inside -”
“God, fuck - yeah. Give me a minute. Give me a second, I’m gotta put it in, I just - ”
His grip on Suguru’s ass is gonna leave bruises, but he’s eager about it. Wonders if Suguru’s gonna let him take pictures of it, Satoru’s fingertips imprinted on his skin as his hole gets stretched over his knot. It’s hot that he’s dizzy for half a second, head spinning, and he grips his cock too tight, choking the blood flow just to keep himself from cumming.
“Satoruuuu -”
Suguru’s begging for dick. He has to give it to him, it’s his duty as an alpha, isn’t it?
He fits the head of his cock against the eager hole that’s drooling for him, and even though Suguru’s shaking with it - it still feels like an impossible task to push against the tightness of him. Satoru has to bully the tip inside of Suguru’s tiny little hole, and he grits his teeth tight through the pressure of it. Inches his way inside carefully, taking him time, drinking in the sight of Suguru’s body stretching to accommodate the throbbing girth of him.
He feels the way Suguru’s body yields under the penetration, swallowing every inch of Satoru’s cock and greedily sucking him. Satoru bottoms out inside of him and Suguru cums just from that, and his hole milking at Satoru’s cock with firm pulsations. Satoru starts thrusting recklessly, impossible to control the animalistic need to breed, and it only takes two-three thrusts before his knot is swollen enough to catch at the rim of Suguru’s ass.
Between them, there’s a mess of fluids, and Satoru presses his sweaty forehead to Suguru’s nape, licks whatever bits of skin he can get his tongue on. Wants Suguru all over his tastebuds, in his nose. His knot keeps expanding so thrusting becomes impossible, all he can do it rut against Suguru’s ass as his balls grow tight.
He’s got fire in his belly, and he’s chewing on Suguru’s shoulder, desperate and shaking, grunting like an animal through all pressure and tightness and impossible to breath, and then suddenly all of it just breaks. His dick starts pumping big, fat loads deep inside Suguru’s body, his knot pulsing in time with his erratic heartbeat. Suguru body keeps shaking against him, spine arching back, the back of his head resting on Satoru’s shoulder. Eyes rolling back and eyelashes fluttering wild, mouth open as he moans. He’s all blissed out and cum drunk now that he’s knotted, running on omegan instincts and impossible to control himself. Each squeeze of Suguru’s ass around his knot forces another load of cum out of his body, makes him feel lightheaded.
And he can’t stop grinding against Suguru’s ass, moving his knot inside and repeatedly rubbing against his prostate.
“You needed this so bad,” he’s feeling victorious, and now he kinda gets it why they used to say alphas had to conquer an omega. Satoru very much feels like a conqueror right about now, “Had to fuck you nice and hard, didn’t I?”
Suguru would never let him talk like that if he was in his right mind, but luckily both of them have plausible deniability like this. Satoru kisses against the back of Suguru’s neck, nuzzles above the edge of his collar as they’re knotted together. It feels like bliss between then, and the cramped space just makes it better. All the alpha/omega bonding pheromones are mixing up between them, making everything just feel cozy and intimate. Suguru’s purring in his arms, and right now, Satoru’s feeling like he’d bite the throat off anyone that would threaten to take Suguru away from him.
It takes about fifteen minutes for his knot to start deflating, and the haze starts lifting along with it. By the time his cocks slips free from Suguru’s body, body of them are shifting in the small space they have. All the peaceful intimacy is forgotten, and between then it’s just awkwardness.
Suguru makes a face when Satoru pulls out, and cum drips out of his hole. He’s probably sore, and he looks uncomfortable, and he tries to pull away from Satoru even as Satoru’s struggling to pull his pants back up and tuck himself back into his boxers.
God, this is excruciating. He should say something.
“Suguru - ” he starts, but he’s cut short.
“No. Don’t talk to me.”
Ouch. Merciless.
Suguru looks mildly disgusted, scrunching his nose and grimacing when he moves slightly. Satoru winces when he thinks of all the cum he pumped into Suguru’s ass and how it’s going to drip down his legs for the rest of the day.
“Listen, Suguru, I’m sor- ”
“No, seriously - I don’t wanna hear it.”
And just their luck, it’s right then that the cursed artifact opens up and lets them outside. Suguru is quick to rush out and put distance between the two of them, but his legs can’t really hold him properly so he ends up slumping against the wall. Satoru wants to help him and he just gets hissed at.
Usually Satoru’s not the kind to get offended easily, but something about this whole thing really fucking blows, and it’s a hit to his ego. He’s feeling kinda oversensitive.
“What the fuck’s wrong with you? One minute you’re creaming on my cock and then - ”
“Shut up, oh my god, do you not know when to shut up? I don’t want to hear anything you have to say.”
Suguru’s face is all red and he’s closing in on himself, and suddenly Satoru feels bad.
“ Tsk . I really am sorry, you know” he says, and kicks the ground aimlessly, looking away. The warehouse is full of cool artifacts and normally he’d love to stick around and play with them, but now he’s just bummed.
“Ugh. Must you act like a hit puppy and look at me with those eyes? You didn’t do anything wrong, I just don’t want to talk about it. In fact, I’d feel better if we can just pretend this never happened, alright?”
Satoru sticks his hands in his pockets and slouches. He nods once and resists the urge to ask if he did well, if Suguru felt good. He has to bite his tongue against his impulse, actually.
Suguru makes him wait outside a bathroom while he tries to clean himself up, and Satoru uses that time to give himself a speed run between liking his friend, fucking his friend, and getting over his friend, all in about ten minutes.
When Suguru comes out of the bathroom, he’s already mostly used to the idea. Mostly.
“So…” Suguru starts, awkwardly, shuffling a little, “...I’m sorry this happened. It’s not gonna happen again.”
“Yeah. Whatever. No worries.”
There’s a tense second of silence before Suguru sighs.
“You understand this is very embarrassing for me. And it’s not like I can control my heats and - ”
“Forget it, it's fine,” Satoru says, looking at him over the rim of his glasses. Suguru looks genuinely apologetic now, and it feels pretty sucky, because he really liked fucking and now it feels like it’s something they’re supposed to take back. But at the same time, he realizes that this situation is so much more embarrassing for Suguru than it’ll ever be for him, “We don't need to talk about it if you don’t want to.”
Suguru sighs, relieved.
“Thank you.”
“Sure. Don’t sweat it.”
“And it’s just a one time thing, I promise.”
Satoru’s a little sad to hear that, but he’s not gonna let this get between them.
“Right. One time thing. Never gonna happen again. Got it.”
The second time it happens, it’s about three months later.
During that time, Satoru thinks both of them did a really good job of ignoring the fact that they had fucked. Satoru barely even thinks about it, most of the time, and he’s only jerked off to the memory of it a few times since then, but not too much. Instead, he tries looking for porn with a particular type of omega - male with long dark hair and fox eyes - and he swears it’s not because he wants to envision Suguru, it’s just that suddenly he realized that’s the type he prefers, irregardless of his attractive and delicious classmate that allowed Satoru to knot him and then said they’re never gonna to that ever again.
(maybe it’s a little because of Suguru, thought he’s not going to admit that)
(and he jerks off to thinking about it often , especially when they’re on missions together and Suguru takes off his jacket and fidgets with his collar a little, whenever Suguru’s a little heated and sweats the pheromone blockers, or whenever he gets whiff of his hair - )
He’s hornier than usual and has to up his rut-inhibitors, because he’s feeling on edge more often, and every once in a while he finds himself growling at people, baring his fangs at their kohai and auxiliary managers, giving off possessive pheromones when Suguru has to talk to people.
"Stop being a dog," Suguru admonishes him, but to no avail. It has the complete opposite effect, because Satoru’s inner alpha sees it like a challenge, a feisty omega that he gets to break in and make him submit, and that’s even more fun and before he knows it, he's horny for Suguru all over again.
"You're embarrassing me, you know. We can't go anywhere without you acting like a horny mutt, and if you can't stop growling at people, I'm asking Yaga permission to muzzle you."
"What? No . I haven't been muzzled since I got my first rut."
"Then please behave! You're growling at people and it's weird, and then they look at me like I'm supposed to calm you down," Suguru rolls his eyes, "Just because I'm an omega doesn't mean I have to deal with whatever testosterone overload you're having."
"Harsh, Suguru. If you talk like that to me, I'm well within my right as an alpha and older than you to bend you over my knee and discipline you," Satoru snorts when he sees Suguru glaring at him. Suguru’s really pretty when he’s angry like that.
"You're three months older than me."
"It counts!"
He immediately pokes Suguru in the ribs, repeatedly, until he starts laughing.
“Quit it, quit it - you asshole, leave me alone - ” but he laughs really pretty and his face gets all red. Satoru’s stomach flips when he sees him like that. Suguru tries to slap his hands away and pull at his short hair, and it makes Satoru want to purr because it’s - fun.
Cute.
It sparks something inside him.
And then, when Yaga makes them train together, it’s not as easy to ignore anymore because whenever Suguru sweats or whenever he has to take his jacket off, Satoru’s dick instantly notices it. When Suguru gets flushed from physical exercise and he fiddles with the collar, Satoru’s cock goes painfully hard in his pants, but he’s always looking for opportunities for it too, just because Suguru’s scent is so maddening.
Satoru thinks Suguru wants him too, again, but neither of them talk about it, and they’re just dancing around it.
They’re outside on the training grounds, and Yaga-Sensei told them to keep each other busy while he’s at a meeting, and Shoko just dipped as soon as he left. Usually they have more of an audience than this, but now since they’re alone - none of the first years around either -
Well.
Satoru grins and takes off his jacket.
“If you win,” Satoru says as he unbuttons the sleeves of his shirt, “I’m letting you boss me around for a week. But if I win -”
“What do you want?”
Suguru crosses his arms over his chest as Satoru rolls up his sleeves.
“You let me buy you a new collar.”
“What?”
Suguru’s eyes go wide.
“You heard me. You let me buy you a new collar. The one you have is ugly and cheap and it’s clearly bothering you.”
“It’s basic! I don't need a fancier collar than this, and there’s nothing wrong with it being cheap since it’s meant to be functional, and - What is it to you anyways?”
“Whenever I go with you anywhere, people assume we’re dating - I would never let my omega walk around with an ugly collar like that, it reflects poorly on my own status as an alpha,” Satoru puts his hands in his pockets and slouches forward, “Hence. I need to buy you a new collar so people don’t think I’m a cheap.”
“Why do you think I wanna be associated with you like that?"
Satoru doesn’t say anything, he just looks at Suguru over the rim of his sunglasses, the sleeves of his shirt rolled up over his elbows, and eyes Suguru up and down. His white shirt is tucked into the high-waist of his pants, highlighting his waist and the curve of his ass.
Suguru looks away, like he’s off-kilter and distracted, and Satoru - instead of giving Suguru any time at all to prepare, he just throws himself at him and tackles him to the ground, arms around his waist and slamming the breath for his lungs. Both of them tumble to the ground, kicking up dust, and Suguru yells at him as he digs his palms into Satoru’s shoulders and pushes.
Satoru doesn’t relent.
"What are you doing? That’s cheating, you’re fucking - " he shouts. He lifts his knee to jab into Satoru’s side, but the momentum rolls them once, twice, and Suguru is flat on his back again.
Satoru laughs, all bright grins and overbearing strength.
"It’s not cheating! It’s just taking advantage while you’re distracted!"
Suguru’s fighting style is different than his - he’s normally so graceful and on point, and slips away from Satoru’s grasp and teases him about being slow. The only way to win anything against Suguru is to overwhelm him from the start, and Satoru’s learned - through numerous sparring matches - that bodying him at the beginning and not giving him any room to breathe is really the only tactic to apply here.
If you give Suguru a chance to escape, he will. If you let Suguru set the parameters of their fight, he’ll never even let Satoru get close, and normally he doesn’t mind being teased like that, but -
Suguru shoves up, hands pushing and whole body heaving, and throws Satoru off of him. He sits up and tries to hook Satoru’s leg, but Satoru moves out of the way. He grabs Suguru’s shoulder and pulls him down, and soon they are grappling and pulling and pushing all across the dirt, into the lawn, until Suguru manages to pull himself to his feet again. He leaves Satoru sprawled on the ground, and kicks him in the thigh as he moves away.
“You’re an asshole and a brute, and - and - ”
“Heh.”
Satoru sits up on the grass and puts his hands behind himself, legs spread in front of him. He leans back and smirks as Suguru berates him. His hair is all messy, falling out of his bun, his white shirt got grass stains, and Suguru’s face is all red. Cute. Fucking cute.
"Don’t you wanna play anymore? If you give up, I’m winning by default.”
He grins and Suguru scoffs at him. Suguru puts a hand on his side and presses against it. He walks over to Satoru and kicks his tabi-clad feet against Satoru’s boots, and then walks forward until he’s looming over Satoru, feet on either side of Satoru’s hips.
Satoru just looks up at him and thinks - if Suguru wants to sit on his face to smother him alive, it’s worth it.
Alas, he doesn’t sit on Satoru’s face, just in his lap. It’s still good, even though it’s a bit of a downgrade. It’s embarrassing because his dick is absolutely hard in his pants, so as a response he puts an arm around Suguru’s waist and throws him off, flips them around. Suguru’s back against the grass and Satoru on top of him, grinning sheepishly at him even as Suguru scowls.
“You bruised my ribs,” Suguru says, accusingly.
“Did I? I’m sorry - let me check.”
Suguru puts a hand on Satoru’s chest and pushes him up, and Satoru goes along with it, balances on his arm as Suguru raises himself on his elbows. He runs a hand down Suguru’s side, pushing slightly until he hears him hissing.
“Hurts?”
“Mmhmm,” Suguru moans as Satoru’s fingers can’t stop pushing against his side.
At this point, he can still sorta kinda claim this is the kind of thing friends do with no ulterior motives, but when he pulls Suguru’s shirt out of his pants, it gets a little trickier to justify it.
He puts his hand on Suguru’s waist and drags it up. Suguru holds his breath under the attention, looking not at Satoru but at his hand and the way it glides over his skin. He pushes Suguru’s shirt up along with his caress, right under his armpits, and he grabs the hem on Suguru’s shirt and raises it to his mouth.
“Bite down on this.”
Suguru does, but he raises an eyebrow at Satoru just to show that he’s definitely caught on to the trick.
There’s definitely a bruise forming on his side, about as big as Satoru’s hand, and when he presses his palm against it and pushes down, Suguru grits his teeth and moans. Satoru runs his tongue over his lower lip and then bites it.
Aw hell. If Suguru bites his head off, he’s willing to risk it.
“I beat you,” he says, and he hooks his finger in the O-ring of Suguru’s collar, “I get to claim you now.”
Suguru snorts
“Old laws don’t work anymore. You need to do more than this to claim me.”
“Well, technically…”
He wants to be an asshole and say that Jujutsu Society Higher Ups still accept Claimings based on Old Laws, and they wouldn’t mind it if Satoru were to invoke such a law in his favor. Sure, they’d need to do an official Public Claiming, but that’s just because Higher Ups are lecherous old men too and they’d love a good show.
Satoru has no plans of doing any of that.
"Satoru, whatever you wanna say, don't."
So Satoru concedes and pulls Suguru into a kiss by his collar. He licks Suguru’s lips to get him to open up, rubs his tongue against his. Presses himself on top of him and grinds his hips down.
"Suguru - "
He whines between kisses. Suguru turns his face to the side, eyes closed, head back, Satoru kisses his cheek and jaws and licks over the edge of his collar.
“What do you want?”
Sounds breathless.
“Let me fuck you.”
He grabs Suguru’s thigh and puts his leg around his middle, grinds his cock against Suguru’s and makes the other boy groan. Suguru’s omega scent is hot and needy, bubbling pheromones under his skin, summer sun hot against Satoru’s back and making his shirt stick to his uniform. The heat’s getting to him, and Suguru’s scent is intoxicating.
Suguru doesn’t say anything, but when Satoru runs his fingers over the buttons of his pants, he sighs and unbuttons them himself, shoves Satoru's hand under the waistband. Satoru brushes against his dick and goes straight between his cheeks just to feel how wet he is. He drags his fingers over his crack and pushes two of them inside.
Suguru gasps and Satoru kisses him to silence him, pushes his fingers in and out of his hole and then pulls out, gathers moisture and takes his hand out of Suguru’s pants. His fingers are dripping, slick spreading between them and down his hands, he shows it to Suguru.
“You’re so wet, babe. No way you’re not gagging for it.”
Suguru’s face goes bright, bright red, and he pushes it against the crook Satoru’s shoulder. He smacks Satoru’s chest and whines.
“You’re so embarrassing. You’re so embarrassing. Ugh . Yes, you can fuck me, but pull out before you knot me. I don’t wanna get stuck with you out in the open.”
Satoru makes him sit face down, ass up, his palm pressing between Suguru’s cheeks and pulling his pants down his ass just enough to fuck him. Suguru’s dripping hole is so cute too, slick running between his thighs and down over his balls, twitching excitedly, and Satoru lines up his cock against it, pushes inside slowly and then pulls back out.
He pushes in just enough so that Suguru’s hole stretches a little around him, and then he pulls out to rub the head of his cock over his hole, and then does it again and again, until Suguru’s thighs shake with anticipation and frustration. He arches his back and tries to push against Satoru and fuck himself on his cock. Satoru doesn’t let him, though, he puts a hand on Suguru’s hip to keep him in place while he teases him with the same slow, shallow, barely there penetration until neither of them can stand it anymore. Then, when he feels like he’s going crazy and Suguru’s scent is muddling his brain, he pushes into him, tip to root slowly.
He tries to keep a slow-and-steady pace, but Suguru pushes back against him, and he can’t resist it, soon enough he’s driving into him ruthlessly. Suguru moans in time with his thrusts, and Satoru grabs his arm and pulls back so he can hold onto him as leverage.
“Fuck, are you gonna cum, baby? You want me to make you cum?”
Suguru doesn’t answer with his words, he just looks at Satoru over his shoulder, red faced and shiny eyes and frowning eyebrows, and open mouth moaning, Jesus, he’s so hot. And his pheromones around them mixing together, and the wet sounds of his thrusting. Satoru keeps fucking into him and Suguru finishes with a shout, his hole spasming and pulsing around Satoru’s cock and pushing him over the edge too.
He pulls out just enough to avoid knotting him, and he holds his swollen knot in hand and squeezes it as the length and tip of his cock is still inside Suguru.
“Satoru - Satoru - ngh -”
Suguru moans and his eyes roll back, and he puts an arm in front of him as a pillow and leans his cheek against it. One thing about omegas - all of them love getting filled up, and Suguru gets soft from it, droopy and a little drunk on the sensation of it.
When he pulls out completely, he just has to stare a little, because Suguru’s hole drips with cum and slick and it’s erotic, and his hole twitches and fuck , Satoru just wants to dips inside it and -
“Ugh. You - !! I told you - ”
Suguru sounds pissed, and it effectively breaks the afterglow spell, especially since one moment is chastising Satoru and then getting up on shaky legs and pulling his pants up.
“What’s wrong? What did I do?”
His knot isn’t even fully deflated and his head is all stupid and slow. He can’t actually figure out why Suguru is pissed with him.
“Yeah? You said I shouldn’t knot you, you didn’t say I shouldn’t - ”
“Well I thought you’d get it! Now I have to - ”
Suguru makes a face while buttoning up, and he glares at Satoru, and Satoru wishes they could go back 10 minutes ago when Suguru was moaning and clenching around his cock.
“It’s dripping down my - ! I hate you.”
Satoru wants to apologize but then right as he opens his mouth, he realizes that Suguru’s hands seems shaky as he’s buttoning up his pants, and he’s all - fuck, shaky hands, does that mean Suguru’s legs are still shaky too? Satoru’s semen dripping down his thighs as he walks with shaky legs, and his pretty hole feeling used and -
“I can see your thoughts on your face,” Suguru says, angry , “All alphas are horny dogs.”
With that, Suguru turns around and leaves, and Satoru has to scramble to sit up and get his clothes in order too so he can run after him.
“Suguru! Where are you going?”
But Suguru doesn’t respond to him, he just flips him off and continues walking.
Satoru isn’t sure if this is progress or not.
