Chapter Text
Yuuji presented as an omega when he was thirteen.
It surprised anyone who knew him. He’d always been athletic and didn’t have the expected softness of an omega.
Alpha or beta were his only two options, or so others thought. Even from a young age when anyone could be anything—all kids were soft and didn’t smell like anything after all—people cooed that he’d make a great alpha.
Being an omega didn’t bother Yuuji though.
His heats were pretty easy, they only lasted two to three days and it’s not like people treated him that much differently. Before they caught his scent, most assumed alpha or beta from looking at him, and even being an omega only got some raised eyebrows, but no one had really made it a bad experience for him.
(Though Yuuji had heard some horror stories about that, whispered among other omegas. Things were better for omegas for the most part, but those who presented as ‘the’ type: sweet smelling and oh so soft in all the right places—well.
Society always liked to believe it was more progressive than it actually was.)
Luckily though, for the entire year he’d been an omega aside from the monthly heats, Yuuji found it wasn’t bad. And honestly, the thought of maybe being courted someday shot a little thrill down his spine. He figured he’d enjoy that part of it.
Having a heat with Sukuna was a little awkward though.
It began during his first week at the school. When he felt the familiar lick of flames curling in the pit of his belly, he dutifully told Gojo-sensei that he was about to go into heat.
“You don’t take suppressants?” Gojo-sensei asked with surprise.
He shook his head. “Don’t need ‘em, my scent and heats are super mild.”
“Hmm. Well, that’s helpful!” Sensei said cheerfully. “Let’s get you all set up then, shall we?”
Gojo-sensei was exceedingly kind. Normally, Yuuji had a few days of pre-heat as a warning but as Sensei led him around campus, having him see Ieiri-san and gathering up heat supplies, he could tell it was coming up on him fast.
Still, Sensei didn’t even blink as his scent thickened the air between them, just started hustling them towards Yuuji’s room.
He must be a beta, Yuuji figured, looking up at him from the corner of his eye. He hadn’t been able to catch a whiff of the other man, even when Sensei leaned in way too close to Yuuji.
“Here we are! Home sweet home!” Gojo-sensei announced loudly, throwing open Yuuji’s door, causing it to bang against the opposite wall. “We’ll move Megumi away for a few days, so don’t worry about a thing! Your kingdom awaits—” He gestured to the room, bending in a mock bow that made Yuuji snort as he walked past him.
“Thanks, Gojo-sensei! I appreciate it.”
“Mmhm, mmhm. No worries at all! Text me if you run out of supplies. Luckily, since you said it was pretty mild, we can leave food outside your door if you ever get hungry enough to eat more than the energy bars we packed.”
“Right!” Yuuji had been too busy dumping out the bottles of water and stacking them by the floor that he hadn’t noticed until he looked up that Sensei was still hovering in the doorway. He cocked his head with confusion. Gojo-sensei always just invited himself in. Even in their short acquaintance, Yuuji had figured that out quickly enough. An unlocked door may as well mean ‘Come on in’ to the older man. Fushiguro locked his.
Then the realization hit, and he had to fight down a gasp. Gojo-sensei had said ‘kingdom’ and he meant it. He was giving Yuuji space so he wouldn’t feel like Sensei was intruding and cause him to get defensive over his territory.
A rush of pure affection washed over him. It was exceedingly thoughtful. “Sensei! You can come in, I’m only protective over my nest so as long as you don’t touch the bed—”
“Oh goody!” Gojo-sensei cut him off as he bustled his way inside. “How fortunate for you.” He handed Yuuji the other bag, filled to the brim with snacks which he took and wedged between the nightstand and the bedframe. After making sure it wouldn’t fall over, he nodded with satisfaction. There, that should do it.
“Will you be able to make it to the bathroom alright?” Gojo-sensei asked with concern, a finger on his chin in thought. It was down the hall, a communal one for several occupants at a time.
“Yeah! I should be fine.”
“Say!” Gojo-sensei said, slapping a fist into his palm. “I just remembered, omegas need toys don’t they? Sorry, sorry, we haven’t had one before, I just plain forgot. Do you need any?”
Yuuji felt his face flush and he looked at anything but Gojo-sensei waving his hands around. “N-no, I’m perfectly fine!”
“Are you sure?” Gojo-sensei squatted beside him, elbows resting on his knees, knuckles brushing the ground. Yuuji swallowed at their close proximity. Sensei was so tall, it felt like he should be gangly, with such long limbs but he made even the uncomfortable pose look effortless. “I can get you some. Don’t want my lovely student to suffer! It’s no trouble at all.” He seemed oddly intense about it.
Clearing his throat, Yuuji shook his head. “I’m good. I, uh, have my own.”
Gojo-sensei gasped, sounding like an offended mother. “You do? My, my, so naughty! What are they, can I see?”
All the remaining blood rushed to his face (and maybe a small amount shot down to make his dick give a very interested twitch, the fucking traitor) as he started sputtering. Gojo-sensei couldn’t possibly want to see what Yuuji had—??
“Just kidding!” Sensei said loudly, over the top of Yuuji still struggling to say anything that wasn’t unintelligible nonsense, and he stood, heading for the door. “Don’t forget, let Sensei know if you need anything! Lube is included in that.”
Yuuji wheezed out something, maybe an attempt at a reply but Gojo-sensei simply laughed as he closed the door behind him.
What a bastard.
An extremely hot bastard, his mind was sure to remind him later, in the throes of his heat, one hand wrapped around his cock while the other fed a dildo into his slicked-up hole.
He wished he could be on his knees, press the silicone that much deeper inside, make him see stars the way Yuuji liked but he’d accidentally smeared slick on the back of his hand and for a moment his mind thought, It almost looks like lip gloss and all was lost.
Now he could only think about Gojo-sensei’s mouth covering his cock, long pale fingers stuffing him full while he gagged, taking Yuuji all the way to the root. He wasn’t normally into guys, had never masturbated to the thought of one before actually, but the image wasn’t unpleasant by any means.
His toes curled into the bedding before he arched his spine at the thought. Gojo-sensei’s mouth was always so shiny he’d wondered more than once if he wore lip gloss but had never seen him apply any. But it wasn’t natural though, right? They literally gleamed in the sun, that wasn’t normal.
This is disgusting, Sukuna muttered with derision.
“Shut up,” Yuuji spat back, angry at the break in his concentration, the orgasm which had been so close suddenly evaporated back into mere heat. He’d have to chase the peak practically from scratch.
Don’t blame me, brat. You started it yourself with the stupid ‘lip gloss’ thing.
Frustratingly enough, the curse wasn’t wrong. Yuuji was all kinds of distracted, trying to masturbate with Sukuna as an unwilling observer. They were both pretty miserable about it.
Can’t you make this go any faster?
“I’m trying,” Yuuji argued, letting go of his dick and sighing aggressively, flopping back into the bed. He grabbed a pillow and pulled it to his face, muffling a scream into it.
Honestly, everything about the situation kinda sucked. The room didn’t smell like Yuuji enough, outside the bed, making his nerves run a little wild. There was no comforting scent of home here, no Jii-chan clothes scattered around the bed and floor to make him feel safe. The afternoon with Sensei had been the best part of the whole thing, he’d felt taken care of and seen. His inner omega purred with delight knowing that Sensei had taken time out of his busy schedule to make sure Yuuji had everything he’d need. To assure him he’d be a phone call away if anything happened.
Disgusting, Sukuna said again.
Yuuji threw his pillow at the wall with a scowl.
It didn’t make him feel any better, the heat pulsing uncomfortably beneath his skin. The dildo which had slowly been working its way out of him without his hand to keep it pressed inside finally popped loose from all his squirming.
His hole clenched on nothing, making him feel empty and unsatisfied. He whimpered.
Look, the curse said, sounding vaguely pained, through his revolt, you’re a bitch in heat. Why are you trying to imagine a blow job of all things? Fucking get on your hands and knees, fuck yourself with your fake dick and imagine the shitty sorcerer giving it to you like you want, pup.
Yuuji winced. “I don’t normally… masturbate to others. Or at least, not anyone I know.”
Sukuna’s impatience swelled between them. The unspoken, ‘And? What the fuck do I care’ went unspoken but was still distinctly felt.
“I dunno! It’s awkward! Plus, he’s not even an alpha so…” His knee hit his dido accidentally, brushing against the swell of a knot at the base, but proving his point. “He hasn’t got a scent so he must be a beta right?”
A thread of disbelief stretched between them before it snapped and was gone just as quickly. Before Yuuji could ask, Sukuna was already talking.
What the fuck does that matter? This is all fantasy. Imagine him knotting you into next week and popping out white-haired babies, whatever it is that omegas fucking want, I don’t care just do SOMETHING so you can get it over with already.
The thought of actually being pregnant made him wrinkle his nose but Yuuji’s hormones were all for it as he felt a wave of slick gush out of his still gaping hole. “Alright, alright, I’ll try it. Just shut up and let me focus.”
Grumbling, Sukuna did just that and faded a little bit more into the background. Yuuji rolled onto his hands and knees before reaching between his legs for the discarded dildo.
Rubbing the head against his hole, his heart started speeding up. He turned his face to the side so he could breathe. The angle wasn’t great, his hands fumbling with the dildo between his legs, and he wouldn’t be able to get to his cock like this but hopefully he could get himself to the edge and then roll over to finish the job.
Gojo-sensei was behind him, large hands rubbing at Yuuji’s ass cheeks appreciatively, his hard cock bumping into Yuuji’s crack, even glancing off his entrance but never pushing inside.
Yuuji whined, wiggling his ass, trying to look tempting. He bit his lip and started to press the tip of the dildo in, imagining Gojo-sensei teasing him all the while, calling him names as his hands never stopped moving over his skin. Tweaking his nipples, fingernails dragging down his spine before reaching out to tug Yuuji’s head back by the hair.
He let out a moan at the thought, of Gojo-sensei holding him taunt, spine arched as he fed him inch by glorious inch of his cock. When he was fully seated, Yuuji moaned again, louder this time, his heart pounding.
“Feels good, feels so good,” he hissed out between clenched teeth.
Even though it was only the sound of his own voice in the room, it spurred him on even more as his breathing became labored as he began pistoning the dildo in and out.
His alpha was there, draped across his back, muttering in Yuuji’s ear how good he was, how good he felt.
The edge of the knot of the dildo caught the rim of his hole and Yuuji’s eyes shot open. When he had closed them, he had no idea, but he began to chant aloud.
“Gojo-sensei, Gojo-sensei, Gojo-sensei!” Each one was punctuated by another hard thrust.
Want me to knot you, Yuuji? Pump you full of cum? Want me to bite you? Claim you as my own?
Gojo’s voice whispered into his ear and Yuuji slammed the knot inside with a howl as his cock jerked in mid-air and he came so hard, his vision whited out.
He collapsed onto the sheets, body suddenly boneless. He ignored the mess as he heaved for breath, eyes wide with disbelief.
He’d just come from his ass and nothing else. Yuuji had never been able to do that before. Holy shit.
“That was great,” he said with amazement to the empty room.
The rest of his heat passed quickly.
It still wasn’t pleasant, both he and Sukuna could agree on that. But at least it was over with. And if Yuuji felt extraordinarily grateful that Sensei covered his eyes so it was less noticeable that he wasn’t looking right at where his eyes would be well…
Sukuna didn’t call him out on it.
Things settled back to normal. Or settled into his new normal.
His classmates turned out to be alphas. It seemed like most sorcerers were either alphas or betas. It wasn’t that surprising; omegas were the rarest out of the secondary genders, after all.
Still, Yuuji had to admit, being the only omega around was… sort of nice. Although people were originally weary of him because of Sukuna, the moment they got to know him, everyone seemed to be kinder to him. Not in an overly glaring way (and Fushiguro and Kugisaki not at all) but just… in small ways. Ways Yuuji had seen before when a single, attractive omega would enter a room. People flocked to them.
Yuuji had never been an overly desirable omega. His statue, strength, and barely-there scent were unattractive to many. But without many options, people’s hormones probably zeroed in on him as something to take care of.
He didn’t abuse it, but he didn’t mind the little perks when he found them, either.
When Fushiguro got close to his rut, he started doting on Yuuji, just a bit. Sticking closer to his side, shoving random drinks he hadn’t asked for at him. His scent was always bitter, almost like burnt coffee, enough to be off-putting to almost everyone who Yuuji had spoken to about it. It wasn’t until that scent evolved into something that actually smelt like a nice cup of coffee, maybe just a hint too sweet for Yuuji’s liking, that he realized what might be up.
“Say, Fushiguro,” Yuuji began, rolling the bottle of water Fushiguro had wordlessly handed him between his hands. The black-haired teen was standing three steps closer than he normally did.
“Hm?”
Yuuji licked his lips before he decided to just go for it. “Are you, uh, about to rut?”
Equally dark eyes regarded him before they widened with recognition. He took three steps back, then another, just to be safe.
“Fuck, sorry, Itadori.”
“No worries!” Yuuji chirped, not minding in the slightest. “I thought it was sweet.” Fushiguro simply stared at him, his cheeks stained the faintest of pinks. The stare didn’t let up and Yuuji shifted under the scrutiny before he remembered. “Oh! Thanks for the water, by the way,” he said, before twisting off the cap and taking a long chug. Alphas liked to feel like they were taking care of omegas, Yuuji recalled hearing from somewhere.
Fushiguro nodded with approval before he turned on his heel, about to walk away.
“Wait!” Yuuji cried and Fushiguro froze before looking at him over his shoulder. An eyebrow rose in silent question. “Wanna scent each other?” He held out a wrist and wiggled it to show his meaning. Definitely not offering his neck, he wasn’t interested in anything mate-level with Fushiguro. But wrists he could do, they were for friends and family.
“Sure,” Fushiguro said mildly, but he closed the distance quickly enough that Yuuji had to suppress a laugh. He was eager then. That was okay, so was Yuuji, he rarely did this outside of Jii-chan.
Yuuji shoved the bottle of water, recapped, into his armpit and they both pulled up their sleeves. Quickly Yuuji pressed a thumb into each small gland that rested on his wrists, encouraging the gland to swell under his touch, enough for the scent to seep out. Fushiguro watched him closely before doing the same.
It was on the tip of his tongue to ask if the other teen had done this before, but he held back. It didn’t matter, if he hadn’t then Yuuji was honored that he felt close enough to do this at all.
“Okay hold out your arms, palms facing up,” Yuuji said. Fushiguro easily did it, his arms hovering in the air between them.
More instructions he’d heard from other omegas began circling his mind. Don’t let alphas scent you, only scent them unless you trusted them. Come in at an angle, don’t just hover your arms over their hands (otherwise, alphas could grab your forearms and force you down to the ground), keep your torso leaned away, and tuck your shoulders up around your neck. For a pre-rut scenting, do it somewhere public where other people were nearby in case they got pushy.
The empty grounds around them suddenly made the hairs on the back of his neck stand up but Yuuji forced the thought away.
Fushiguro wasn’t going to hurt him.
Still, he made sure to take the advice not to rest his arms over Fushiguro’s hands, just in case. He came in from the side, doing them one at a time.
The whole exchange lasted less than thirty seconds and when it was done, he took a step back and smiled brightly. “There you go! Is it okay?”
He watched the other teen bring up his wrist to his nose and take a whiff. Then his nose wrinkled.
“Hey!” Yuuji yelled, his inner omega feeling vaguely insulted. “What’s with the face?!”
“Coffee doesn’t mix well with grass,” came Fushiguro’s disgruntled reply.
“Well, maybe not burnt coffee,” Yuuji joked with a laugh and Fushiguro sent him a weak glare. “Besides, it’s not grass. It’s knotweed.”
“Like your name?”
“Yeah!”
Fushiguro hummed before he turned once more to go, letting his sleeves fall back down. “Thanks though, Itadori. That was nice.”
“Sure thing!” Yuuji agreed.
Knotweed didn’t particularly smell like anything to people, he knew. But if you broke it open, it smelt sweet, almost zingy, and like freshly cut grass. That’s what Jii-chan said at least. It was a reoccurring thing in their family apparently, last name and knotweed scent, mixed with something else unique.
Itadori’s—omegas and alphas alike—didn’t have a particularly strong scent. To most, Yuuji smelt like grass, sometimes metallic and even then, barely. Jii-chan said that when Yuuji got particularly comfortable he smelt like blood, mixed with knotweed.
It wasn’t particularly pleasing, Yuuji figured, but then again, not everyone was paired with an alpha. A lot of betas wouldn’t be able to pick out his scent, mild as it was.
His mind flashed to Gojo-sensei. Would that be appealing to a beta then? Most were able to pick out something in someone’s scent, that’s why they were able calm down omegas and alphas if need be. Maybe an alpha wouldn’t like his scent, but would a beta be okay with it? Would Gojo be okay with it?
The thought made him squeeze his forgotten water bottle and the plastic crackling made him jolt.
Then Yuuji laughed at himself, feeling sheepish. Stupid, it was stupid. How could he get a crush on someone so soon? And on his teacher no less!
Ah, well. He probably wasn’t that special. Gojo-sensei was objectively very attractive. And was apparently the strongest sorcerer! Yuuji bet he got tons of offers beta, or not.
By the time his next heat rolled around, Yuuji was settled in enough that he felt like he could comfortably ask what he had been considering for some time.
Hopefully, he would go into a pre-heat this time, giving him a day or two to actually prepare, letting him build an actual nest. The last time he figured he was so stressed out from Jii-chan’s death and the whole business with Sukuna that his body just went into overdrive and forced it on him too soon.
So, when Yuuji woke up with a tell-tale ache in his lower spine, all his joints feeling like they were on fire, and a vague ache in his stomach he took a deep breath and prayed he could make it through the day of classes at least.
When Gojo-sensei arrived (late), all three first years already sat in their seats, he immediately thrust his hand straight up, as far as it would go.
“Whoa! Look who’s eager!” Gojo-sensei said brightly, hands out by the sides of his face. “Yes, Yuuji-kun?” he said the ‘kun’ like he always did whenever he used an honorific, sarcastically and with a teasing tilt, to let you know he wasn’t being serious.
“My heat is coming up soon!” Yuuji announced loudly, hand still raised. Gojo-sensei’s smile didn’t move, but the silence implored him to go on. “And I—” he fumbled a little, a flush rising to his cheeks. Yuuji had never actually asked for this before. “And I was wondering if I could get some clothing from you all.” He slapped his hands together in a prayer gesture, squeezing his eyes tight, not confident enough to watch their reactions.
While it wasn’t unusual for friends to ask each other for clothing to get through heats, they hadn’t known each other all that long. To be honest, Yuuji had never been close enough to do this with anyone. He just took stuff from Jii-chan when he needed it and the old man never said anything about it one way or the other. Now that he thought about though, he’d only really seen omegas and betas exchange stuff at school… were alphas normally asked for this or was that only for mated pairs or something?
Right before fear could completely knot up his stomach, Kugisaki’s voice broke through the tension.
“Yeah, sure,” Kugisaki said, sounding bored. He peered over at her, and she pointed at him aggressively. “Just make sure to wash it before you give it back!”
“Right!!” Yuuji agreed easily, smiling wide.
“I’m fine with it.” At the sound of Fushiguro’s measured voice, Yuuji had to fight the urge to wiggle in his seat happily. This was going much better than expected!
“Yuuji wants something from Gojo-sensei too?” he asked, pointing at himself. Yuuji nodded eagerly and Gojo-sensei’s face bloomed with the force of his smile. “Ohhh, this is why you’re my favorite!! I’ll make sure to get Yuuji the nicest thing possible!”
Both Kugisaki and Fushiguro groaned at the same time.
“Why did you even bother asking him?” Kugisaki groused with annoyance.
Fushiguro nodded with agreement.
“All of you guys are important to me!” Yuuji said easily, fighting not to let his voice crack with nerves. Yes, he recognized that it was weird of him to ask for something from a teacher, but Gojo-sensei wasn’t like normal teachers. He literally lived on campus, hung out after hours with them (if he wasn’t busy with a mission or something else), took them all out for food, and texted them regularly.
Gojo-sensei clapped with excitement. “This’ll be great!! Make sure to send Sensei a picture of your nest when it’s all done! I want to see how well you build them.”
Yuuji was too busy agreeing to notice Fushiguro and Kugisaki’s twin expressions of disbelief.
The next morning, his hands were shaking a bit. Yuuji’s heat was fast approaching, there was that familiar ache between his legs. He’d be lucky if he would be allowed to finish out classes instead of being ushered away. With two other alphas in the room, he wouldn’t be surprised if they stopped him at the door. But hopefully he'd have enough time to time to grab everyone’s clothes.
There was a pep in his step as he got dressed and hurried to get to the classroom. He was really excited to build a nest using materials from his friends.
And well, if Yuuji also wanted the excuse to smell Gojo-sensei from up close, that was his business. He was just so curious. Even though Sensei frequently got into Yuuji’s personal space (and Yuuji at times initiated contact himself) he’d never even caught so much of a whiff. It was infuriating, Yuuji had never met a beta with such a weak scent before.
But hopefully that was about to change!! There was no way Yuuji would miss Gojo-sensei’s scent when it was literally right underneath his nose, right??
Upon arriving at the classroom, he found that Fushiguro and Kugisaki were already there.
“Wow.” Kugisaki wrinkled her nose. “You stink already. Are you good to be here?”
“I’m fine!!” Yuuji reassured her. “Ah, but I can leave once I grab the stuff from you guys?”
She got up to open a window with a sigh as Yuuji stood in the center of the room, fidgeting with nervous excitement.
“Did you get everything you need?” Fushiguro asked.
“Why do you smell like blood of all things, did you smell like that before Sukuna?” Kagisaki added.
“Yep and yep!”
The classroom door slid open and Yuuji’s heart flew into his throat as he turned. “Gojo-sensei!”
“Oh, I didn’t miss the exchange yet, did I?” the white-haired man asked with a smile.
“Not yet!” Yuuji shoved his still-shaking hands into his pockets, grinning widely.
Kugisaki sighed. “Let’s get this over with before you smell up the room and have us all snapping at each other. Seriously, it’s like a blood bath in here,” she muttered that last part under her breath as if he wasn’t meant to hear.
She dug into her bag before withdrawing something and holding it out. Gratefully Yuuji took it from her. The fabric was fuzzy and soft and without thinking he rubbed it against his face. “Oooh, it feels nice!” Her scent, something spicy and floral, flew into his nose. Pulling it away, he realized it was a beige sweater with white stars.
“Yeah, yeah,” Kugisaki said with annoyance. “Just don’t stretch it out!”
“I won’t!” Yuuji promised.
“And read the washing instructions!”
“I will!”
“And—”
Fushiguro cut her off, nudging Yuuji’s shoulder. “Here’s mine.” Kugisaki hmphed with annoyance but Yuuji gently grabbed the offered white, stretched-out T-shirt. It was obviously well worn, the fabric a kind of aged softness that only came from being rewashed frequently.
“This is great!! Thanks so much you guys!”
Gojo-sensei pushed Fushiguro aside and ignored the teen’s grumbling. “My turnnnn!” he sang before presenting a plastic bag, tied off at the top. “I gave you a couple of options because I wanted it to be the best!”
“Thanks—”
Sensei wrapped an arm around his shoulders and started dragging him towards the door. “Now! Nobara is right, you need to get outta here.”
Shame made Yuuji hang his head, the tops of his ears burning red. “I’m sorry, Sensei, I didn’t mean to be a bother.”
Gojo-sensei cooed as he pushed him out the door before patting his cheek. “Don’t make such a sad face, Yuuji! You’re never a bother. Just can’t have an unbonded pre-heat omega in the midst of alphas, that’s just asking for trouble.” He smiled, all teeth. Yuuji swallowed at the sight, it looked deceptively friendly but felt dangerous. “Don’t forget to send me a picture of your nest!” Then he promptly shut the door in Yuuji’s face.
Racing to his room, Yuuji’s heart felt like it might beat out of his chest. Once he made it inside, he set aside his sensei’s bag before stripping off the first few layers of his nest to position Fushiguro and Kugisaki’s clothes within it. Building up the layers, he smiled as he stepped back. He was pretty messy at times; it wasn’t uncommon for the top layer to get pulled away and discarded, so having their clothes partly buried meant they should survive longer in the shuffle of his heat. He made sure to put them on opposite ends so he could cuddle into one or the other without having the scents mix together. Hopefully, they’d only smell like a mix of himself which made his omega purr with delight.
That taken care of, he tore off his own clothes, letting them fall carelessly to the floor. Normally he’d drop them on the mattress around the edges of his nest just to keep his scent around, but it didn’t look appealing that way and he wanted to send Sensei the best picture he could get once he positioned Gojo-sensei's belongings in the nest. Hopefully the beta would approve.
Swallowing hard Yuuji grabbed his sensei’s bag and dropped it onto the mattress. This was it.
He could feel his heat coming on, his hole twitching with impatience, wanting to be filled already, his inner omega restless and wanting to crawl into his nest. Wanted to feel protected, feel safe, feel secure.
Vaguely, he could feel Sukuna scowl at his instincts but he ignored it. With trembling hands, he undid the knot and then held his breath.
Digging into the plastic, he drew out one of Sensei’s long black uniform jackets. He was so tall! Laying that out on the bed, he continued his search and found a silky pillowcase and a shirt, so large he’d likely be dwarfed in it if he tried to wear it.
His lungs were beginning to burn but he held firm and lifted up the shirt to his face. Closing his eyes, he let out a quick breath before sucking right back in.
Immediately, it felt like all the synapses in his brain fired off at once and he swayed on his feet. He couldn’t even comprehend what the scent was exactly because all his brain could do was scream a chorus of Alpha, alpha, alpha!
And not just any alpha, the best-smelling alpha Yuuji had ever come across.
With a moan, he felt instantly lightheaded as the chub he was sporting before quickly turned into a raging boner as all the blood rushed to his cock.
Nest, I need my nest. His thoughts were frantic and quickly spiraling out of control as his heat roared through his veins, demanding release. Yuuji stumbled into his nest, uncaring for anything else.
Pressing the shirt to his nose, he scrambled to his knees, leaning his torso back, one hand keeping the shirt to his nose while the other wrapped around his already leaking cock.
It only took two tugs before he was cumming, his release slamming through his system as he screamed out a desperate, “Gojo-sensei!!” Alpha.
Took you long enough, Sukuna muttered. I can’t believe you didn’t catch on that he was an alpha, brat. You really are an idiot.
Yuuji felt insane, the release not doing much to relieve him. Whatever snide commentary Sukuna had would have to wait, he barely heard or made sense of anything. Already he felt like he needed to cum again, he could feel his hole dripping slick down his thighs, wanting his alpha to come and fill him already.
“Fuckkkk, fuck,” Yuuji whimpered, falling onto his chest and reaching out for his dildo which had been hidden in between the layers of his nest, grabbing it with one hand. He needed something inside now.
“Gojo, please, please, please,” he pleaded to the air as he started feeding it inside of him. “Need your knot, need you, alpha!!”
That heat was one of his most… uh, memorable ones. Yuuji didn’t normally get so caught up in his hormones that he lost control, but he was a pleading mess, barely able to form a coherent thought that wasn’t ‘Gojo-sensei’ and ‘Alpha’.
It was a little embarrassing to say the least and by the time he finished (in four days instead of his normal two or three), he was nearly burning with the need to understand that had nothing to do with his heat.
He decided the best thing to do was return everyone’s clothes—precisely washed according to the label instructions—separately so he could use the excuse to talk.
After doing a quick handoff to Fushiguro and Kugisaki it was time to approach Gojo-sensei.
Taking a deep breath outside of Sensei’s office, he steeled his nerves and pasted on his normal smile before opening the door and going inside.
Gojo-sensei was laid out on one of the two couches that were crammed inside the office space, which was mostly dominated by a large desk with a computer and a single (uncomfortable-looking) chair across from it. The couches took up the rest of the space, pushed against opposite walls from each other with a coffee table that you had to shuffle sideways to get around in between. Shoved in between one couch and the wall was a small mini fridge.
“Yuuji!” Gojo-sensei cried out happily. “You’re back! Heat finally finished? You took so longggg,” he whined.
“Ah, yeah it was longer than normal this time, I’m sorry about that.” He rubbed the back of his head while Sensei waved him off while sitting up.
“Don’t apologize! It’s body stuff we can’t control, don’t feel bad for taking what you need. Sit, sit!”
Already having stepped into the room put him within range of Gojo-sensei’s reach and he grabbed Yuuji around the wrist without waiting for a reply and pulled him down onto the couch with him. They were completely plastered together, side by side and Yuuji fought the urge to let out a small eep.
Looking up at Gojo’s smile, Yuuji cleared his throat and tried to smile back. “I, uh, brought you your clothes back, Sensei!”
“Oh, you diddd?” Gojo-sensei’s smile widened; he didn’t move away. “How kind of you!”
Right. Awkwardly he held out the same plastic bag Sensei had given him before, without being tied off this time though.
Sensei tore through it immediately. Yuuji watched with confusion. Was he expecting there to be something else in there? Gojo-sensei sat back with a pout. “You washed them?”
He sounded dejected—though like always Yuuji couldn’t detect a scent to confirm the emotion—and Yuuji’s omega went frantic with the need to make things right for the alpha.
“Kugisaki asked me too!” he explained. “I didn’t think you’d want them back without it, I’ve never exchanged clothes before, I’m very sorry Sensei!” He bowed his head slightly to show his earnestness while Gojo-sensei pulled the bag against his chest, wrapping his arms around it, still pouting.
“I was hoping to get Yuuji’s scent back, how disappointingggg.”
Though Yuuji couldn’t see his eyes with the blindfold, he felt like they were looking at him, as a weight of expectation settled on his shoulders. Yuuji shifted, unsure of what was being expected, or wanted, from him.
“I really am sorry! I didn’t know!”
“Stop apologizing!” he chided. Then he sighed deeply. “It’s not a big deal, just a hole in my heart where I thought I’d get my favorite student’s approval with his scenting my stuff but noooo.” The tone was mock upset, but Yuuji still felt guilty.
Trying to figure out some way to soothe the other alpha, Yuuji hit on an idea. Maybe that would work? Plus, it might be able to get his question answered.
“Would you… like to scent then? To make up for it?” he asked flipping over his hands—arms on display resting on his thighs to show his meaning.
“Oh, could we?” Gojo-sensei enthused, his traditional sunny mood already back in place. He shoved the bag to the side before sitting up from his backwards slouch, somehow scooching even closer to Yuuji.
“Um, Sensei?” Yuuji asked as Gojo-sensei grabbed one hand and pulled up his sleeve for him before doing the other.
“Hm?”
“Why, ah. Before—”
Gojo stared at him as he rolled up his own sleeves, waiting patiently for Yuuji to find his voice.
“I couldn’t smell you, before?” Yuuji finally blurted. “I wondered why that was. I thought you were a beta before I smelt your clothes. Even now—” He sniffed the air. Now that he was aware of what Sensei should smell like, he could catch a little bit of a whiff in here, surrounded by Gojo’s things.
It was the scent of ozone, all thunderstorms and rain, sweet and sticky with how much it clogged his senses. There was also a layer of… snow almost? It was a barely-there and Yuuji was obsessed with wanting to smell it even more, to recognize it even deeper, be able to pull out Gojo’s exact feelings from it. He wanted to know exactly what ‘snow’ smelt like on Gojo-sensei and why that even had a scent on the man when before he met him, Yuuji would have said it had no scent at all.
“Ah!” Gojo leaned in much too close, his breath fanning out against Yuuji’s face. He didn’t flinch back, just blinked, waiting for the explanation that was sure to come. “It’s my technique!”
“Eh?”
Gojo-sensei leaned back just enough to be able to put a hand. “My cursed technique! Go on, try to hold my hand.”
Hold his hand?!
Quickly, before he could think too much about it and properly freak out, Yuuji lifted his palm and tried to press it against Gojo’s. His hand stopped in midair and he stared.
“WHOA!! That’s so cool, Sensei! Is it like a force field?!”
“Kinda,” Gojo-sensei said before Yuuji’s hand was allowed through and he twined their fingers. There was an explanation, something about his cursed technique and slowing down time, blah, blah, blah. Yuuji barely heard a word of it, though he watched Sensei’s mouth move the entire time.
Mostly he was focused on the feeling of their hands, which were still intertwined and settled atop their knees that were pressed against each other.
“So basically, it works to trap in my scent! Nothing gets in and nothing gets out.”
“Wow!!” Yuuji said, happy he had caught at least that much of it. “That’s so neat! Do people frequently mistake you for a beta then?”
Gojo-sensei smirked. “No, people usually know who I am and that I’m an alpha before they even meet me, they don’t need my scent to tell them that. And when I’m out with civilians I don’t bother in a crowd of course, but if I’m meeting with people, I tend to let out my scent a bit so they don’t get any stupid ideas.”
Yuuji smiled but it felt all wrong, like someone had smacked his face. I’m the only one who did that?!?! So embarrassing!!
Sensei must have caught that he was panicking, either from his scent or his face, and chuckled. “Don’t worry, Yuuji! I’m not offended.”
He breathed a sigh of relief. “Well, that’s good then.”
“Let’s scent!” Gojo cooed. “I haven’t done this in ages, it’ll be fun.”
“You haven’t?” Yuuji let Gojo-sensei position his wrists, palms up, on his knees, which were turned towards Sensei.
“Nah. Don’t normally care enough too. All my friends are pretty private and don’t like exchanging scents like this. And the students don’t ask for it.”
That was another jab in his heart, thinking about how much of an outlier he was. Gojo-sensei nuzzled his nose into Yuuji’s temple, making him laugh and lean away.
“Don’t feel bad,” Gojo-sensei’s voice was unnaturally soft, his smile gentle. “I’m happy about it.” He rubbed a thumb into one of Yuuji’s scent glands and he had to resist a shiver at the feeling. No one ever massaged them for him, he’d always done it himself, and feeling it swell beneath Sensei’s ministrations was making his body suddenly feel itchy, but in a pleasant way?
He didn’t fully have time to comprehend it before Gojo-sensei was switching to the other side and doing the same before laying his wrists over Yuuji’s and rubbing them together.
“Did they help by the way?”
Gojo-sensei’s voice seemed far away as Yuuji’s head tilted, brain fuzzy before gravity took over making his chin bob down and he jolted straight up, blinking back into awareness.
“Did, uh, what help?” he asked, suddenly lost about what they were talking about. Gojo-sensei wasn’t moving their glands together anymore, but his fingers were wrapped around Yuuji’s forearm, leaving their wrists still pressed close.
“The clothes,” Sensei explained with a grin. “Did they help through your heat? I never got that picture of your nest by the way!”
“Oh, oh! Right, I’m sorry I totally spaced, Sensei!”
More like you immediately came in your pants like a little boy the moment you smelt him, Sukuna hissed and Yuuji gave him a hard mental shove as his eyes widened with panic.
“But they did help, yeah! It was actually super great, I’ve only had nesting materials from Jii-chan, so having everyone else around was… nice.”
Not that Yuuji overly noticed the other two scents, except when he was rolling around from his post-orgasm haze, blissed out and feeling safe and protected, his pack scents surrounding him while Gojo-sensei’s stayed stuck to him throughout. He hadn’t let any of the three items of Gojo’s go for his entire heat. By the time he’d finished, they’d barely smelt like Gojo-sensei at all, completely wiped away by the force of Yuuji’s scent rubbing off on them constantly.
The thought made a flush rise to his cheeks, and he shot to his feet, dislodging their arms and hands from each other.
“This has been really nice, Sensei!” he announced loudly. “But I just remembered, I promised Fushiguro to do a… thing. So, I better get going! I’ll see you later!”
"Hold on." Gojo-sensei caught his wrist and he swallowed down a whine that threatened to bubble up his throat. "What's that?" he asked, jumping to his feet, the action filled with cat-like grace.
Yuuji made a questioning noise before Sensei's thumb brushed against the back of his neck, right over his scent gland and his shoulders shot up. He wiggled out from Gojo-sensei's touch, body feeling itchy as he turned. Sensei was standing there with his hand still raised in mid-air.
"On your neck?" he asked. "Did you spend your heat with someone?" Unsubtly Sensei leaned towards him, sniffing loudly.
"No!" Yuuji said, slapping a hand against the back of his neck, face burning with embarrassment. Now he realized what Gojo-sensei had meant.
Why didn't you heal that?! he thought-shouted at Sukuna who merely gave him a vaguely disgruntled grunt back.
Sensei cocked his head but it was clear Yuuji wasn't leaving the room without an explanation. "I, uh, did it myself. With my fingernails. During my heat." Each sentence was punctuated with a wince, as he wanted more and more to sink into the floor. Vaguely, he had a memory of pinching the back of his neck, right over his scent gland, while desperately crying out Gojo-sensei's mark, for his claim. He'd cum harder than he'd ever cum in his life. Yuuji was quickly learning all sorts of new things about himself, the more he spent his heats while thinking about Gojo-sensei.
Humiliating, to be remembering this now, right in front of the man in question.
"Ohhh! I see!" The tension that had filled the space suddenly disappeared, as if it was never there at all. "So silly of Yuuji, you shouldn't be hurting yourself!" He tsked and Yuuji smiled, the edges of it feeling manic.
"Yeah, I'll be more careful! Now, I better go."
“Bye-bye!” Gojo-sensei said voice pitched higher in a cutesy English accent. He waved as Yuuji all but bolted from the room, face on fire and he lifted one of his wrists to his nose, finding it positively reeking of Sensei.
That at least made him giggle a little and he slowed, looking around to make sure the hallway was empty except for himself before he pressed the meat of his palms beneath his eyes, digging them into his cheekbones. He didn’t care about the mild discomfort because all he could smell was them.
Their sweetness, Yuuji’s milder and barely there, Gojo-sensei’s overbearing and tacky seemed to combine into something otherworldly, a perfectly there balance of the two that was undertoned by Yuuji’s own metallic blood and the sharp cold of a frost.
It transcended all attempts to describe it. Yuuji just knew without a doubt that there was no one else that could match his smell so perfectly, that would elevate it into something nice, no not even nice, divine.
Happiness felt like it took root in his lungs and as he laughed—the sound bouncing in the empty hallway around him—Yuuji felt like his chest expanded with the force of his utter bliss.
