There aren't many things Yuuji would not admit to. He tries to be an honest person as much as he can, not keen on lies or pretenses, but there is always a secret or two that he needs to keep to himself. Whether that is to save face or for the better good of others, it’s his own business. For example, Yuuji would never admit to his aniki's face that he had actually sneaked out with Sukuna when he was still underage and had gotten his first taste of an alpha knot at seventeen. It’s all on Sukuna's well being, and Choso’s peace of mind, that Yuuji doesn’t speak a word of it, ever.
Another thing Yuuji would never admit to, it’s how much he likes Sukuna during pre-rut. That secret had nothing to do with Sukuna's well being -arguably, the alpha would debate that Yuuji admitting to it would be best for him-. However, it’s rather for Yuuji to save some dignity in their relationship. It’s already bad enough that he had admitted once to getting turned on by Sukuna's possessiveness.
Stroking Sukuna's alpha's ego any further than it already is would be the wrong move. Yuuji would never live it down. Besides, Yuuji is a modern omega. Independent and with a successful career, he has no business fawning over an stupid alpha being overly territorial, caring and needy for a whole week. He’s smart enough to think with more than his cock, thank you.
Is why Yuuji is currently trying to stifle a shit-eating-grin under his hand as he found Sukuna clutched in front of their fridge, cursing at the ‘useless shitty thing’ for not fitting the obscene amount of groceries Sukuna had bought, again, for the third time that week.
Yuuji allows his omega a moment to preen over all the fresh vegetables and fruits Sukuna had stacked on the low drawer. The frozen strawberry cheesecakes and nato that Yuuji loved to have during his heat. Three rows of water bottles and fresh peach and orange juice. Over the counter there are more supplies for his nest, a new set of fluffy pillows and blankets. Yuuji smiled with pride.
It isn’t until he spots the blanket patterned with little tigers, neatly folded, hidden between the pillows -the third one Sukuna had bought-; that the grin Yuuji had tried to hide before dies for itself on his face.
It was supposed to be a joke. Sukuna had teased him saying he could use it for when they'll have a new born pup, and as much as Yuuji loves his mate’s instincts pushing him to provide and make sure his omega has everything he needs during his rut, Yuuji isn’t fond of mindless spending. His grandfather had taught him the value of everything and how to be responsible with his money, so Yuuji would never have to depend on anyone or suffer from reckless wasting. Sukuna being filthy rich isn’t going to deter Yuuji from giving him a lecture.
He sighs loudly, putting all his disappointment and annoyance in his thickening strawberries scent, heavy with a hint of bitterness and exasperation. Yuuji watches Sukuna immediately stop in the middle of pushing more food into the fridge, his spine straightening like a bow as soon as he catches a whiff of Yuuji’s soured scent. A deep frown between his eyebrows when he looks back at him.
"What's wrong?" Sukuna asks, standing up and walking to him, groceries forgotten. Opening his arms to engulf his mate in a hug, before he even reaches Yuuji.
Yuuji very pointedly crosses his arms, avoiding Sukuna. "What do you think is wrong?"
Sukuna stops on his tracks, eyeing Yuuji’s closed off posture. The way his eyebrows pull together in annoyance and then confusion, reaching to tug at Yuuji’s arms, almost sulkingly, has the omega cooing internally -Sukuna is so far up in his pre-rut already-. Instead, Yuuji makes his pheromones flare up, making clear his disappointment as Sukuna doesn’t immediately acknowledge his wrongs.
"What is it?" Sukuna sounds annoyed as he tugs at Yuuji’s arms harder, pulling him against his chest into a tight hug, even if Yuuji still has his arms crossed. The alpha nibbles on the mating scar atop Yuuji’s neck and shoulder, visible from the loose collar of one of Sukuna’s shirts that Yuuji sleeps in. He tries to appease him with his own pheromones, scenting him.
Yuuji shudders as pleasure runs through his spine, feeling Sukuna's fangs dig in his skin, exactly where he had claimed him a couple years ago, but Yuuji is a strong omega, he isn't going to be swayed so easily.
"What did I tell you not to buy again?" Yuuji tries to push Sukuna away as he hears the alpha start growling, slipping in and out of his rut state. "Sukuna." He whines.
"I'm listening." Sukuna grumbles. "I don't know why you're being a brat so early." He mumbles against Yuuji’s skin, nosing his neck.
"Maybe if my dumb alpha would listen to me instead of his instincts, I wouldn't have to be a brat." Yuuji pinches Sukuna in retaliation, making the alpha glare back at him at being insulted, catching Yuuji’s hand to stop the jab at his ribs.
"I'm not a dumb alpha." He says, squinting his eyes at Yuuji to try to intimidate him into admitting he’s on the wrong. Yuuji is not amused.
"You are. I told you not to buy anymore of those blankets and you forgot, again. For the third time. Sounds pretty dumb to me."
Yuuji watches the words sink on Sukuna's face as he tries to remember among the haze in his pre-rut riddled brain. If Yuuji wasn’t so busy being a responsible mate, he would snap a picture of his expression for teasing material.
"They had a new color." Is what Sukuna says, looking all serious and determined like he did the right thing and expects to get praised for it.
"I don't need one of each color, Sukuna." He gapes.
"Why not?" Sukuna asks, looking at Yuuji as if he’s the one being unreasonable here.
"Because I don't!" Yuujj says exasperatedly.
"But-"
"No buts." Yuuji cuts Sukuna off, glaring at him. Pulling off the special glare Yuuji reserves for hot headed alphas. Sukuna's eyes widen for a second, his scent turning clogging. His fingers twitch around Yuuji’s waist before digging into his skin in soothing circles. Sukuna grumbles under his breath before dropping his head on Yuuji’s shoulder.
"What did you say?" Yuuji presses, pinching Sukuna again. The alpha flinches and holds Yuuji’s other free hand, successfully trapping both in between his.
"M'sorry." Sukuna mumbles, reluctant and prideful even as his instincts make him look ridiculous with the way he's draping himself all over Yuuji with a remorseful scent.
"You can't buy any more of them, understand?" Sukuna starts saying something back but Yuuji beats him to it. "Even if they have new colors."
Sukuna clicks his tongue and mumbles about 'stubborn omegas' , but doesn't let go of Yuuji or stops nuzzling his mating gland.
The rest of the morning passes with Sukuna clinging to Yuuji’s back while he puts away all the unnecessary things the alpha bought in his run to the grocery store. Until Yuuji’s scent is coated again in warm sugar melting over strawberries, Sukuna drooling all over his neck. Yuuji dutifully cleans his mate’s chin when Sukuna is not assaulting his mouth with messy and dirty kisses.
They’re dozing off on the couch, after breakfast, when Yuuji’s phone rings, arousing Sukuna from his slumber with a growl. Yuuji rolls his eyes as he reaches for his phone. No one is supposed to be calling him today. He took the entire week off from work to stay with Sukuna. His brothers also know that Yuuji will be busy. He frowns as Nobara’s ID glares at him from the screen.
When he picks up, there's a ruckus of shouts and groans on the other side of the line. "Noba?" He asks. Sukuna growls low in his ear, pheromones flaring for a second at the mention of other alpha. Yuuji gives him a weak slap on the arm tightly wrapped around his waist.
"Don't Noba-me, Itadori Yuuji, I'm going to kill you!" Nobara yells on the phone and Yuuji winces instinctively. "Where did you put the damn contract we were supposed to be handing off first thing in the morning to Nanami-san? He's about to rip my head off if I keep telling him to wait."
Yuuji frowns, puzzled. "I told you it was over my desk. Inside the black folder."
"Well, there's no black folder over your desk. Oh my God! Nanami-san is coming."
"Hang up." Sukuna mumbles in Yuuji’s ear, pressing himself against him and rubbing his hard on against the omega’s ass.
Yuuji thinks about Nobara’s demands for a second, glancing at his portfolio lying on the other couch, the black folder glaring daggers at him from its place inside his bag. Oh, shit.
"I swear if Nanami-san gives me a reprimand, I'll make you suffer tenfold this humiliation." Nobara threatens.
He could blame it on an irritated Sukuna, demanding Yuuji to come out of the 'damn building' the night prior, as to why he forgot to leave the contract him and Nobara had been working a month on where he said he was going to, but whatever the excuse is, Nobara is gonna hang him anyway.
"Shit." He stutters into the phone.
"Don't tell me you took it home. Don't say it, Yuuji."
Yuuji swallows audibly. "I won't say it if you don't want me to."
"You! You're so dead if you don't get it here in 20 minutes. I'll kill you with my bare hands!"
"But-"
"Get your ass in here now, Itadori!" Nobara hangs up as Yuji cringes at the use of his family name by one of his best friends. He’s on his feet in a second, or at least he tries to, fighting Sukuna's iron grip on him.
"Where you going?" Sukuna asks, pulling Yuuji back on the couch with him, eyes still closed.
"No, Sukuna, listen." Yuuji struggles against him to turn on his embrace, pinching Sukuna's cheeks to wake him up. "I have to go."
His last words make Sukuna open his eyes wide. He glares at Yuuji like he has gone insane, and his hold tightens around him.
"No." Is what he says. No room in his tone for arguments. There's even a hint of his alpha voice in there.
"I have to. I just gotta head to work quickly and I'll come back in less than an hour." He tries, pushing against Sukuna's chest.
"No. You're not going anywhere."
"I have to, Sukuna. It'll be quick."
"No." Sukuna growls, this time pushing Yuuji flat on his back on the couch and looming over him, caging him under. His eyes are flashing a low red, pheromones heavy and overpowering. Yuuji feels himself melting under. During pre-rut Sukuna won't let him out of his sight, but if he doesn't get to the office quickly, he may even lose his job.
"Sukuna. Listen to me."
"You're not allowed to leave." Sukuna interrupts, his scent turning sour as Yuuji doesn't immediately submit to him.
"Alpha, please." Yuuji whines, he has no other option than to appeal to Sukuna's alpha's need to tend to him. Sukuna is going to make him pay for it once he slips fully into his rut, but that’s a problem for future Yuuji.
Sukuna's scent flares, turning distressed and protective, eager to make the hurt in Yuuji’s voice go away. "Why? You don't have to leave our house. You have everything you need here." He complains.
"I know, I know. You have done the best for me, but I need to get to the office. It'll be quick. Just this time, please?" Yuuji makes his pheromones soothing, clearing Sukuna's feverish mind a bit. He sees the emotions swirl on the alpha’s expression until it settles in a deep annoyance between his eyebrows.
"Fine.” Sukuna relents. “ Fuck . I'm gonna kill your idiotic boss. I told you to quit ages ago." Sukuna grumbles, standing from the couch and pulling Yuuji with him.
Yuuji runs to grab a pair of pants and some boxers that aren't ruined with slick and runs to the front door with Sukuna glued to his back. He forgets his portfolio again and has to run back as Sukuna yells and grumbles some more.
The ride to the office is filled with traffic and Sukuna almost physically fights someone as he snaps at every other driver that pisses him off. His knuckles are white with how hard he's gripping the steering wheel. Yuuji tries putting his hand over his thigh and rubbing soothing circles, apologetically, but Sukuna swats him away.
Yuuji bolts out of the car the second Sukuna parks in front of his work’s building. He tells Sukuna he’ll be quick about it but the second he steps foot outside, Sukuna yanks the door closed and pulls Yuuji against him.
"You're not going alone." Sukuna says through gritted teeth. He looks every bit the feral alpha he's about to be once his rut hits fully. Muzzled hair and flushed skin, his glaring is so deep people cower away when they glance at the both of them on the sidewalk, and his pheromones smell sour. Fighting him is futile though, so Yuuji just sighs as he drags Sukuna inside the building.
It isn't until someone audibly gasps at the sight of them in the elevator that Yuuji understands what a shit show this is gonna be.
Sukuna is posturing all the way, looming over Yuuji as his hand circles his waist possessively, pushing the omega against his chest. His shoulders are squared up and jaw set. His fangs on display. But that's not even the worst part.
The worst part is that Sukuna is the CEO of Ryomen Enterprises, prime alpha and one of the biggest names of the tech world, and Yuuji is dragging him across the building of the Gojo conglomerate like he's parading any other alpha by the knot. There's going to be shit about this. Maybe even some paparazzi pictures. Sukuna's reputation is gonna get dragged, not like Sukuna gives a fuck about it, but Yuuji does.
A headache has settled in Yuuji’s head by the time the elevator stops at his department floor and Sukuna pushes him out. He's basically carrying Yuuji now, walking faster to the counter and snarling at every employee that gets in his way. Yuuji can only wince and apologize quickly at the terrified looks they get.
He almost feels relieved when he sees the front desk in sight behind the glass doors. He'll drop the portfolio with Ijichi-san and ask him to please deliver it to Nobara. He doesn't want Sukuna spreading his pheromones in the enclosed space of his office, filled with other alphas and omegas. But as per usual, when Yuuji fucks up once, the universe fucks him over too for good measure. He spots his boss, Gojo, hanging over the desk, as soon as Sukuna throws the glass doors open, startling him and Ijichi-san.
Gojo looks back with icy blue eyes, assessing whoever just almost ripped his office apart. His eyes land on Yuuji for a second and soften immediately until he sees Sukuna's arm around him. The way he smirks at them makes Yuuji feel dread churn in his stomach.
"Yuuji-kun! What are you doing here? I thought you were on leave." Gojo says with an amicable smile, walking up to them. Sukuna stops mid-step and pushes Yuuji behind him. Posturing even harder, standing straight to his full height to shield Yuuji from Gojo's sight.
"Don't look at him." Sukuna threatens for good measure, growling at the other alpha.
Gojo smirk widdens even more as he postures back to the challenge. He's taller than Sukuna, less broad, but his prime alpha pheromones are as clogging. Yuuji can feel his mate shaking with rage. He tightens his grip around Sukuna’s wrist to stop him from throwing a punch.
"Charming as ever, Ryomen”. Gojo mocks. “What brings you here?"
Sukuna snarls in response.
Yuuji ducks from under Sukuna's elbow to look at his boss. "I forgot to give Kugisaki this. Sorry, Ijichi-san could you please give it to her? We’ll leave now." He extends the file to Ijichi-san who is watching the three of them with wide eyes and shaking like a leaf behind the desk. He feels bad for even asking, but instead of the assistant reaching for it, Gojo takes it. Getting closer to Sukuna and making their height difference much more obvious. The challenging pheromones are thick as fog and it permeates the whole vestibule.
"I'll hand it, Yuu-chan." Gojo purrs, his hand lingering a second too long on Yuuji’s, enough for Sukuna to launch himself for it, ready to rip it off, as he pushes Gojo, hard, away from them.
It takes every bit of strength on Yuuji’s body to hold Sukuna back.
“Fuck off.” Sukuna barks, using Yuji’s hold on him to turn him around and against his chest to hide him away under his chin. Humiliation runs down Yuuji’s spine.
Gojo goes back to his previous stance, reclining at the front desk, watching them as he laughs like he’s witnessing the best joke of the decade. Yuuji makes a mental note to swap Gojo's morning coffee with Nanami-san's on Monday and watch his boss suffer from the bitter Americano.
"We're leaving now!" Yuuji says without looking back, pushing Sukuna out of the doors, only allowing himself to finally breathe when Gojo's laughter is no longer on hearing range and Sukuna's is glued to his back, whispering murder against his nape as he scents him inside the elevator. He hears someone gag when they get down on the first floor, the metal box now permeated with angry alpha pheromones. How is he ever going to go back to work when everyone's eyeing him with either pity or horror as Sukuna drags him out of the building? His life's ruined. So much for being a successful independent omega.
Sukuna pushes him into the passenger seat and secures his seat belt like Yuuji’s a five year old. He’s pretty sure they drive past the speed limit but nobody stops them on the way to their apartment.
When they arrive, Sukuna beats him out of the car first and drags Yuuji all the way to their penthouse. Once he has double checked all the locks on their door he turns to Yuuji, heaving, now fully into his rut. His eyes feverish. Yuuji just accepts his fate with an apologetic smile.
Sukuna backs him against the table in the lobby and nuzzles his neck, pressing all his weight against him, trapping Yuuji between his body and the cold marble. His low growls send shivers down Yuuji’s spine and he ruts back against Sukuna’s hips, pressing his own hard on against Sukuna’s.
“Mine, my omega. Need to protect.” Sukuna mumbles, repeating it like a mantra as he gropes Yuuji all over, marking his neck with hickeys all over his mating scar. “Mine, mine, mine, mine. ”
“Yes. Yours, Sukuna. Only yours.” Yuuji soothes, breathless as Sukuna pushes his hands under his pants and underwear to grope his ass, pushing two fingers inside his dripping hole. Yuuji keens at the intrusion, moaning in pleasure when the thick digits press just right against his prostate, opening him up for his alpha.
Sukuna hauls him over the receiver, knocking the pictures over, while he rips Yuuji’s pants down. Yuuji knows better than to complain when Sukuna is so far up his possessive strike, besides, he’ll have no room to worry about the mess once Sukuna is pounding into him without abandon.
The alpha kneels between his legs as soon as Yuuji drips slick all over the surface, pushing Yuuji’s legs up to bury his face between his ass cheeks and slobber all the slick like a starved man. Yuuji moans high in his throat, toes curling as Sukuna’s tongue pushes inside him, sucking him hard. The fingers are back inside him hastily, fingering him quickly until he cums with a shout, his shirt ruined with cum and sweat.
Sukuna stands up with a self-satisfied smirk, kissing Yuuji messily, letting him taste his own slick and cum. His lips are forceful against Yuuji’s, stealing his breath and making him whine when he nibbles on them, sucking his lower lip into his mouth to soothe it after. Yuuji moans wantonly, pressing his hips back against Sukuna’s cock, the head breaching inside, but his mate pulls back. Going back and forth, teasing him with shallow thrusts.
“Beg, omega.” Sukuna says, voice low with arousal, sucking Yuuji’s neck and collarbones in an arrangement of blossoming red and purples.
“Please.” Yuuji whines, desperate to be filled, to feel Sukuna inside his tight walls stretching him open. He glances down to see Sukuna’s knot already swelling, flushed and so big, Yuuji salivates. “Knot me, please. Sukuna, alpha , fuck me!”
Sukuna thrusts inside him in one go, pushing his knot inside with animalistic strength. It's rough and fast with the way Sukuna is letting out all the pent up frustration and rage. Yuuji can only take it and scream his mate’s name as Sukuna uses him to milk his knot. He’s sure the back of his thighs are gonna be bruised after, and Sukuna’s rut has only started.
“Fuck, you feel so good and hot inside. Taking me so well.” Sukuna grumbles, pistoning his hips at a punishing pace. His alpha chasing his orgasm to pump the omega full of cum, breed him just right. With Sukuna’s pups. For Sukuna only.
The plethora of mine, mine, mine, mine starts again while Sukuna buries himself to the hilt, trapping his knot inside Yuuji, pressing just right against his prostate. The omega throws his head back as he feels his orgasm wash over him like a wave. Voicing Sukuna’s broken name in a choked out moan when thick cum fills him up.
“My mate, my omega.” Sukuna mumbles against the mating scar, pouring satisfied and possessive pheromones, rocking back and forth shallowly to mess Yuuji’s insides.
The whole week Sukuna’s rut lasts, Yuuji has to deal with the same treatment 24/7 and the grumpiest and most possessive Sukuna has ever been. He whines constantly and doesn't let Yuuji go anywhere alone. Yuuji complains once and Sukuna fucks him into the mattres with his face pressed into the pillow and his ass up. After that, Yuuji just pampers his alpha extra hard and moans louder as per Sukuna's request. He even caves and uses the three different colors blankets in his nest to Sukuna's prideful delight and unbearable smugness while he talks about using them for three different pups. Yuuji doesn’t mention the arousal curling in his belly as cums trails out of him. If he weren’t taking Plan B, Sukuna’s pillow talk may just come true.
He has to take another two days off since he can't properly stand up or even walk, as his mate growls in his ear to quit already, trapping Yuuji against his chest with all his limbs. Yuuji considers it as he bears with Gojo's teasing on the phone, before agreeing to show up on Wednesday, much to Sukuna's rage.
