Chapter Text
“Nanami, you’re…”
Gojo doesn’t really need to speak it out loud. The dark red flush sitting high on Nanami’s cheekbones and the sweat starting to bead on his forehead already say plenty, even without the thick, heavy scent of sandalwood and rose filling the cramped room.
An omega.
Nanami grits his teeth and when he goes to take a step back he wobbles, as if about to fall. Gojo catches him by his elbows and is surprised by the violence with which Nanami rips his arms out of Gojo’s grasp.
It all started with a mission gone wrong. Gojo had gone along with Nanami after rumors of a possible previously unknown special grade curse surfaced that required investigation. With the discovery of Okkotsu Yuuta and Orimoto Rika in the fall, all such rumors were now being investigated even if, like with this case, there was little evidence to back it up.
While Nanami probably didn’t need the assistance of a special grade, Gojo doesn’t usually get the chance to work with his fellow sorcerers, so he’d jumped at the opportunity to be Nanami’s partner even though the man himself was less than pleased to see it was Gojo that showed up.
Honestly Nanami hadn’t even needed any help at all in the investigation. But then things suddenly went a little… hinky. The cursed spirit they encountered, just your run of the mill semi grade 1 curse, sprayed some foul kind of liquid at Nanami, and at first Gojo worried it was acid or something toxic and corrosive, but when Nanami merely took the surprise in stride and dispatched the curse with ease he brushed it off.
They parted ways at the little inn they had chosen to stay at because Nanami refused to just let Gojo teleport them to and from their remote, distant village mission and insisted on taking the train the entire five hours up north and staying in the village during the duration of the investigation. Of course Gojo could just teleport himself home and make Nanami take the train alone but… where was the fun in that? Plus, he never usually gets the chance to spend so much time with the prickly beta and it’s worth the soreness in his lower back and butt just to listen to Nanami begrudgingly talk about the book he’s currently reading.
Gojo went to change and relax while Nanami washed the curse’s slime off himself, and when he returned to Nanami’s room later on to inquire about dinner, that’s when the smell had hit him.
Omega in heat.
Nanami looks miserable with it and Gojo watches as he hugs his arms around his middle, attempting to draw the loosely tied robe more tightly shut. It’s not enough to hide his scent from Gojo’s Alpha nose however, and Gojo has to steady himself against the intoxicating aroma perfuming out from Nanami.
Breathing through his mouth only makes it worse. He can taste Nanami’s smell on the air and Gojo quickly slides the door shut behind him, locking it in place before anyone else can come along and get any ideas from Nanami’s heat scent.
“I didn’t…” he begins but Nanami shakes his head hard, taking a shuffling step away from Gojo.
“No one knows. I can’t… They don’t like omegas doing sorcerer work. They would downgrade me, and refuse to let me fight anything stronger than a Grade 2, if they even let me do anything at all. I take suppressants and use scent blockers to hide my status, but I was an idiot and I forgot them at home this time, and then the stress of getting doused with that curse’s slime, not knowing what it was going to do to me, must have provoked my heat. I thought if we were done within a few days then it would be fine and I’d just call out sick if I got my heat when we returned to Tokyo, but it’s been so long that…”
Nanami trails off, sounding frustrated and tired.
Gojo swallows thickly, knowing how difficult it must be for someone as intensely private as Nanami to have to trust him with this.
“Is there– Do you have a normal heat partner I can go get?” Gojo asks him, as much as it pains him to do so.
He wants to be Nanami’s heat partner. He’s wanted Nanami long before knowing he’s an omega, and now that he does know it feels like fate. But Nanami looks acutely uncomfortable and almost afraid of Gojo right now and Gojo doesn’t want to hurt him.
But Nanami shakes his head again and curls his trembling fingers around fistfuls of the robe.
“I don’t. Not since Yu,” he admits softly and that takes Gojo aback.
Nanami spends his heats alone? Even on suppressants, his body would force a heat at least two or three times a year. Gojo can temper his ruts with medication and a healthy dose of masturbation if necessary, but for an omega to spend their heat alone, to not have a beta or fellow omega to even nest with?
“It must have been hard,” Gojo murmurs and that’s apparently the wrong thing to say because Nanami’s back straightens and his eyes go hard around the edges.
“I’ve been doing just fine on my own!” Nanami snaps, crossing the room towards Gojo and jabbing an angry finger at the center of his chest. “I don’t need you, or any other Alpha, to tell me what I need. Especially not you.”
Okay, that stings a little. Not unwarranted though, Gojo supposes he had sounded a little condescending in that moment whether intentional or otherwise. He grips Nanami’s hand to prevent the continued shove of his finger and then sighs, trying to decide the best course of action.
He could attempt to teleport them back to Tokyo, but he’s never teleported an omega in heat before. The teleportation process is already a bit taxing on anyone that isn’t Gojo, and he has to assume that would go double for someone not currently up to full strength, omega or Alpha.
“I know you don’t. I’m sorry, Nanami. I wasn’t trying to insult you, I just… I know spending a heat alone can be really difficult. I was trying to praise your strength, not condescend,” Gojo sighs softly, and that seems to take a bit of the bluster out of Nanami’s sails.
He deflates slightly and when he looks up Gojo has to bite the inside of his cheek to retain his composure because Nanami is wrecked.
His forehead shines with a thin layer of sweat and his hair, still damp from the shower, curls messily against it in a way that makes him appear younger. He hasn’t had a heat partner since Haibara, which means it’s been years since Nanami has been exposed to an Alpha while in heat. Gojo swallows thickly when Nanami makes a small, weak little sound at the back of his throat and unconsciously leans in to nuzzle his face into Gojo’s neck where his scent glands are.
“Nanami… Nanami, what do you want me to do?” he asks roughly, resisting the urge to wrap his arms around Nanami’s sturdy body and pull it against his own.
Nanami smells so good and the fog of omega heat pheromones is starting to make it difficult to string his thoughts together. The omega pauses as if suddenly realizing he’s rubbing himself all over Gojo and draws back, clearly embarrassed.
The robe is slipping open and Gojo can see the tantalizing expanse of Nanami’s bare chest beneath it. He wants to get his mouth on him so bad that it’s watering just at the very notion of tasting the omega.
“You don’t want this,” Nanami says firmly, planting his hands on Gojo’s chest and pushing. “It’s just the pheromones talking. Every omega in Japan wants you as their Alpha, and I’m not so pathetic that I’m willing to be just another omega notch in the belt of Gojo Satoru.”
Gojo frowns and wraps his hand around Nanami’s wrist to prevent him from running away before slowly removing the bandages wrapped around his head. Nanami twitches when they fall away, but Gojo is used to that type of reaction by now.
The glittering glass shards of his eyes are unsettling, but Nanami stands his ground and stares resolutely back at Gojo, refusing to look away.
Good.
“I have not had an omega partner in as many years as you, Nanami. Not since… Well. It’s been a long time. And while every omega may want me as their Alpha because of my bloodline and cursed technique, I don’t really care what every omega wants. I asked what you want.”
Nanami is trembling now and when Gojo carefully draws him back in he comes easily, face pressing into his throat once more to drink in the steadying vanilla Alpha scent of Gojo.
“I don’t allow just anyone to touch me, Kento,” Gojo murmurs, and he knows the gamble of using Nanami’s given name without permission pays off when he shivers in the circle of his arms. “Only my students, and the few people I care about, can even come close. And if you tell me to leave right now then I will. I’ll go get you whatever you need to make it through your heat on your own and I’ll stay outside your door the entire time to make sure nobody disturbs you. We’ll go back to Tokyo once it’s over and never speak about it ever again. But if you want me to stay then… I want to stay. If you’ll have me.”
He wants to stay so badly. Gojo’s feelings for Nanami are complicated and confusing and he highly doubts they’re reciprocated in any way but if there’s even a glimmer of a chance that Nanami wants him around then… Gojo is going to take it.
Nanami makes a sound that’s dangerously close to a whimper and curls his fingers tight around fistfuls of Gojo’s uniform. His eyes are dazed and out of focus when he looks up at Gojo again and Gojo can’t resist the urge to gently brush his sweat sticky bangs back from his forehead, wincing internally at the heat radiating from Nanami’s skin.
“I’ve only… Just the once. With Yu. I’m not– I don’t know how this goes.”
Gojo struggles to swallow around the fierce, possessive thrill of Alpha excitement that surges within him at the knowledge he’s pretty much the only one to ever see Nanami like this. While Gojo has refused to take an omega partner since Suguru, he has experience with betas, though… not in a very long time. Not since Nanami called him and asked to return to the sorcerer world.
“It’s okay, Kento. I’ll take care of you. I just… I need you to tell me that’s what you want. Plainly. Before your heat takes over and I can’t trust that you’re giving me real consent,” Gojo whispers, and he aches to kiss him but he forces himself to wait for Nanami’s answer, electric blue eyes boring into Nanami’s dark hazel-brown ones.
Nanami stares back at him, and he stares, and for one heart stopping second Gojo is afraid that he’s going to say no after all, but then he keens, high and shivery in his throat, and tightens his grip on Gojo.
“Please. Gojo, please.”
Gojo crushes his mouth to Nanami’s between one breath and the next, bringing the omega’s body against his own with a greedy, possessive growl. Nanami’s skin is on fire and Gojo fumbles the belt of his robe open even as he licks his way past slack lips, tasting of heat and Nanami.
Nanami’s knees buckle but Gojo catches him before he falls, picking him up with ease and hauling Nanami over to his bed. When he drops the omega onto it he has to stop a moment to catch his breath though because Nanami is a vision like this and Gojo desperately wants to imprint it on his memory forever.
The thin cotton robe is puddled under him, caught in the crooks of his elbows and lending a debauched sort of lewdness to the omega that nudity alone could not manage. His skin is flush pink and shiny with sweat, and when Nanami unconsciously spreads his thighs there’s slick on them. His cock is small, like with most male omegas, lying hard against his hip and already dribbling pre-come with how aroused he is.
“If only you could see yourself…” Gojo murmurs, absentmindedly unzipping his jacket and peeling it over his head along with his shirt and dropping it to the floor.
Nanami whimpers and reaches down as if to cover himself, only to be stopped when Gojo surges forward and pins his wrists above his head to prevent that. He looms over the omega and stares intently down at him, drinking in the sight of his needy, desperate face.
“Don’t hide from me. I want to see everything,” he growls, pleased when Nanami shivers at the rough rumble of his voice.
Gojo buries his face in the crook of Nanami’s throat and opens his mouth to inhale the sweet, musky scent of him, rolling it over his tongue and filling his lungs with the aroma of sandalwood and rose. It pairs so perfectly with Gojo’s own vanilla scent.
“Don’t,” Nanami whines faintly and Gojo knows what he’s asking, placing a soft, reassuring kiss to his sensitive scent gland.
“It’s okay, Kento. I promise I won’t bite,” he croons before soothing over the gland with his tongue.
At least, not until Nanami asks him for a bite. That’s definitely putting the cart before the horse a bit but Gojo doesn’t care. He’s wanted to make Nanami his long before he even knew it was possible.
Gojo’s family will hate it. He’s sure they have plenty of ideal mates in mind for Gojo to choose from, all from wealthy sorcerer families and capable of bearing powerful heirs, but Gojo has no interest in that. Especially not when the one he truly wants is tipping his head back and exposing more of his throat to Gojo’s lips, so vulnerable and trusting.
An omega’s scent glands are probably the most sensitive part of their body. Normally invisible, especially beneath the high collar of Nanami’s tightly buttoned shirts, they’re now red and swollen on either side of his neck, extremely tender to the touch of Gojo’s tongue, laving flat across it in soothing, easy strokes.
Nanami’s arm curls tight around Gojo’s shoulders and there are fingers in his snowy hair, trembling weakly as Gojo laps at the puffy gland. The scent of sandalwood hangs around them like a cloud and when Gojo snakes a hand down between them to wrap around Nanami’s painfully hard cock the smell only intensifies.
He’s suddenly glad for the scent dampeners he had noticed around the doors and windows of their hotel rooms because he’s pretty sure they’d be able to smell Nanami all the way back in Tokyo by now otherwise.
“You’re so pretty like this, Kento…” he purrs, switching to Nanami’s other scent gland as he starts to stroke him off.
The way Nanami is clinging to him is certainly quite the ego booster. Gojo kisses the spit slick scent gland before surrounding it with his lips and giving it a short, quick suck. Nanami’s hips jerk off the bed and he sobs, but it sounds like an uncomfortable sound rather than a pleasurable one so Gojo backs off again, apologetically soothing over the gland with his tongue once more.
Too sensitive then. Maybe once Nanami is closer to the end of his heat and the glands are less puffy and sore he’ll try again.
He thumbs at the head of Nanami’s cock instead, keeping up the steady, gentle pressure of his tongue on his scent glands. He wants to pull at least one orgasm from him to take the edge off and give Nanami back a semblance of his self control. The omega can’t even speak right now with how desperate and overheated he is, and Gojo doesn’t like that.
He wants to hear Nanami cry his name when he comes around Gojo’s knot for the first time.
“Can you come for me, Kento?” Gojo asks softly, combing Nanami’s sweaty blond bangs back from his forehead so he can press a kiss to his temple. “Alpha wants you to come.”
He punctuates this with a rough, twisting upstroke around Nanami’s cock, growling with delight when the omega arches off the bed and comes with a ragged cry of pleasure. Gojo milks him through his orgasm, watching it dribble over his fingers and onto Nanami’s belly. His chest is heaving and Gojo plants a soothing kiss to his breastbone, patiently waiting for him to come down from the high.
“Gojo…”
Nanami’s voice sounds tired and Gojo leans up to look at him, taking in the shadows beneath his eyes and the deep flush sitting high on his cheekbones. He’s more lucid after an orgasm but probably not for very long. Gojo releases his cock and brings his hand to his mouth, absently licking away the streaks of white staining his fingers.
The color filling Nanami’s face only darkens, and his mouth drops open slightly as he watches Gojo lick up his come. Gojo grins, and curves down over him to kiss him sweetly.
He expects to be pushed away or bitten by the normally prickly man, heat or no heat, but Nanami is soft and pliant in welcoming the kiss, making a faint noise when Gojo licks between his lips to share the taste of his own come with him. His expression is pinched when Gojo draws back however and Gojo hums curiously at him, cradling his palm against his face to prevent him from turning away.
“What is it?” he asks, trying to put a bit of Alpha force into the question.
There’s conflict in Nanami’s face and, if Gojo isn’t mistaken, a pinch of shame and embarrassment too. Gojo softens a bit. He’s been hiding his omega status for so long and after years of spending his heats alone he probably barely understands what his instincts are asking for.
“What do you need, Kento? It’s okay to ask. Anything you want, I promise I won’t tease,” Gojo swears, raising his hand in a mockery of a salute. “Sorcerer’s honor.”
Nanami scowls at him and the expression is so familiar and distinctly Nanami that it actually makes him relax a little.
“Your… scent,” he mutters finally, so softly that Gojo barely catches it.
“What’s that?” Gojo laughs, grinning when Nanami shoves at his chest.
“You said you wouldn’t tease,” Nanami snaps angrily, lip threatening to curl into a snarl.
Gojo relents and kisses him apologetically, unsurprised to find Nanami’s mouth shut in a firm line against his lips this time. He probably deserves that, it’s a bit mean to pick on an omega when they’re in heat. Especially one as proud and capable of throwing him out the window as Nanami.
He leans off the bed and goes fishing around on the floor before he finds his discarded jacket, grabbing it up and dropping it onto Nanami’s chest without a word. The omega blinks at him uncertainly, but the way his fingers curl possessively around the fabric tell Gojo he guessed right.
Omegas are driven by scent and scent marking, especially when they’re in heat. Nanami probably has a nest at home for his heats that’s filled with the safety and security of his own smell, and maybe even some pilfered items with the scents of people he trusts, if he has any. Without their nest an omega would already feel pretty exposed and vulnerable, but also being in an unfamiliar place, in a strange hotel, forced to out himself as an omega to someone who he probably only barely tolerates?
If Gojo can offer some small semblance of comfort in the form of the strong, vanilla Alpha scent clinging to his clothes then that’s what he’s going to do.
“Actually…”
He climbs off the bed and finds his discarded t-shirt as well, tossing it to Nanami before quickly leaving the room and disappearing down the hall towards his own room next door. He’s relieved that there’s only the faintest hint of Nanami’s heat smell in the hallway, and the inn had been fairly unoccupied anyways when they’d checked in a couple days ago.
Gojo gathers up the unwashed bedding, his towel from that morning’s shower, and the few dirty shirts and pants from the past few days, and returns to Nanami’s room, pleased to find him still lying on the bed with Gojo’s jacket pressed to his nose.
It’s not a great nest, all things considered. He does his best to circle his sheets and the heavy comforter around Nanami, adding in the heavily scented towel and dirty laundry to make an approximation of a nest. Nanami lies there and watches him through all of it, Gojo’s jacket draped protectively over him.
“There,” Gojo declares, climbing into Nanami’s makeshift nest with him and sitting back on his heels. “I’m sure it’s not as good as the one you have at home but it’s better than nothing right?”
Nanami’s face is flush pink to the tips of his ears and it’s at that moment Gojo realizes what he’s technically saying by building Nanami a nest.
Alphas their age make nests for omegas they’re courting with the intention of mating some day. It’s an enormous romantic gesture, and one with very strong, very direct implications. It’s bold and probably a bit rudely presumptuous considering Nanami doesn’t even like him as a coworker nevermind as a potential Alpha, but…
Gojo says nothing. He doesn’t apologize or try to insist that it’s not like that, or make excuses for his actions.
He just kneels there and stares back at Nanami, watching as the omega hides his embarrassment behind Gojo’s coat.
“Are you waiting for a written invitation?” Nanami snaps finally and Gojo laughs, leaning over him until their faces are level.
“Mmm, perhaps. Or maybe I just want to hear you beg for your Alpha to touch you,” he croons, kissing Nanami through the fabric of his coat.
Nanami jerks it down to glare at him, but it’s somewhat undercut by the hazy heat fog starting to creep back into his tired brown eyes. He shivers when Gojo strokes his fingertips over his scent glands, and tips his head to the side to expose them more to his touch.
“It’ll be a cold day in hell before I beg you, Gojo,” Nanami mutters under his breath.
“Satoru,” Gojo interrupts, gripping Nanami’s chin between his long fingers and turning his face back towards him. “Call me ‘Satoru’. Considering what we’re about to do I think it’s a better fit.”
Nanami gives him a look that suggests he’d rather suck on a lemon and Gojo figures it’s something they can work on next time. If there even is a next time. He’s kind of banking on Nanami either being secretly in love with him and welcoming Gojo as a regular partner and, perhaps maybe one day, his Alpha, or that Gojo just fucks him so good Nanami decides it’s much more enjoyable to keep him around than suffering through his heats alone. Gojo would far prefer the first option but, well. Beggars can’t be choosers. He’ll take what he can get.
“You’re pretty when you pout,” Gojo teases, easily catching the hand that comes swinging for him and turning his head to press a kiss to the open palm instead.
Nanami wrenches his hand back with an undignified sound, staring up at Gojo like he’d just bitten him. It makes Gojo chuckle and he watches Nanami as he undoes his belt and pants, drinking in the fresh color that rises in his sallow cheeks when he realizes what comes next.
“If you want to change your mind now is your last chance, Kento,” Gojo murmurs, cocking his head curiously at the omega. “While you’re still lucid and unimpeded by your hormones.”
But Nanami just shakes his head, tugging Gojo’s jacket up to his nose once more and taking what is, quite possibly, a completely unconscious inhale of Gojo’s scent.
“I’m not changing my mind. It’s just been a while since the last time,” he mutters and Gojo realizes with a start that he’s nervous.
Nanami Kento is nervous. About embarrassing himself in his inexperience? Or that it might hurt?
“Was your time with Haibara good?” Gojo asks carefully, leaving his pants open but still on for now as he slides down to lie on his side next to Nanami.
He strokes the omega’s hip soothingly but doesn’t push for more just yet. He wants to understand what has proud, strong, fierce Nanami Kento looking so uncertain.
“It wasn’t bad. We were both inexperienced kids fumbling around our first time. I was in heat without really knowing what it meant, but understanding that it would be something I’d need to hide if I wanted to stay as a sorcerer. Getou-san was an exception because of his cursed technique and power, they couldn’t excommunicate him for being an omega even if they wanted to. But I was just… me. Yu promised to keep it a secret, and help me with my heat until I could get on the suppressants. But neither of us really knew what we were doing. It was… Too fast. Even with my heat easing the way we were stupid, and when he knotted me I wasn’t prepared for it, and it wasn’t bad but it wasn’t…”
Nanami trails off, sounding exhausted.
Gojo gets it. He remembers his first time with Suguru, and the fumbling of inexperienced hands and not enough prep. Still.
“Mm, I understand. I’d like to think I’m a bit better at this than a virgin teenager though,” he chuckles, still idly petting his fingers over Nanami’s hip.
The omega is unconsciously rocking his body into his touch now, and he looks mollified by Gojo’s words despite the touch of arrogance in them. Nanami needs an arrogant Alpha right now to make him feel safe and protected during the vulnerability of his heat after all.
“I’ll make it feel good, Kento. I promise. If you look even the slightest bit uncomfortable then I’ll stop and we’ll figure something else out, okay?”
Nanami watches him for several long moments, clearly sizing him up. The intensity of his stare is kind of sexy but Gojo knows better than to tell him that if he wants this to continue, so he wisely keeps his mouth shut and waits, ghosting his palm up Nanami’s side.
“Stop treating me like a blushing virgin bride,” Nanami grumps at long last, aiming a sour look at Gojo that just makes him grin.
“Roger that!”
He sits up and gives him a mock salute, then pulls Nanami up along with him despite his immediate dismay.
“Chill out, Kento. I just want to get this off you,” Gojo coos, tucking Nanami’s face against his scent glands to soothe him as he tugs the sweat soaked robe from his body.
Nanami is still clutching the jacket to his chest when Gojo gently settles him back against the pillows again, and Gojo can tell by the way his hands are shaking that his heat is starting to creep back in.
He’ll need to run to the store and pick up food and drinks to get Nanami through the rest of his heat sometime soon but first he needs to take care of his omega.
Gojo leans down and presses a soft, chaste kiss to Nanami’s lips, then slips his hands beneath his knees and spreads his legs wide. His cock is filling up again as his heat arousal makes a return, and there’s shiny slick on his ass and thighs, no doubt soaking into the bed beneath him. It’s too late to bother with a towel at this point and Gojo makes a mental note that he’s… probably going to have a hefty dry cleaning bill to pay.
But when Nanami makes a thin, reedy noise in his throat and presses Gojo’s jacket to his nose again to drink in his scent, Gojo can hardly even pretend to care about that.
“At some point during your heat I’m going to bend you over the bed and eat you out until you’re so wet I could put just about anything I want in you,” he purrs, kissing the inside of Nanami’s knee and watching as he shudders.
“If you do anything weird to me I will kill you,” Nanami warns, his voice muffled by the jacket still pressed to his nose.
Gojo huffs out a laugh against his knee before allowing his legs to slowly slip down to rest against the bedspread once more. That’s all the warning Nanami gets before he’s flipped onto his front, and when he tries to raise up on his hands to no doubt read Gojo the riot act Gojo stops him with a firm hand on the back of his neck.
Nanami goes all quivery at the gentle pressure Gojo is exerting on his scent glands and slowly sinks back down into the mattress, face pressed into the tangle of his jacket.
“You’re so sensitive, Kento… Normally that wouldn’t work on an omega your age, but you’re so unused to being touched by an Alpha that I can turn you into goo with just a light touch to your glands,” he teases, but not unkindly.
He kisses the back of Nanami’s neck, right above where he’d place a mate bite, and Nanami makes a reedy whining sound deep in the pit of his belly. He arches his back and it’s clear that his heat muddled omegan instincts are more than welcoming to being claimed by Gojo, even though Gojo knows that is by and far not something Nanami is close to being interested in right now.
Certainly not from Gojo.
So he settles for another kiss on the top knob of his spine and then presses Nanami’s shoulders back down into the bed. He grabs one of the pillows and stuffs it under Nanami’s hips to raise them up, knowing better than to assume the tired, overheated omega can stay up on his knees without some help.
But then he notices the tension in Nanami’s shoulders and pauses, cautiously rubbing his palm up the length of Nanami’s back like one would soothe an injured animal.
“Kento? Tell me what you want,” Gojo orders, putting just a touch of Alpha authority into it so Nanami can’t refuse.
His response is muffled by the jacket he’s buried his face into however and Gojo has to pry it away from him so he can get a look at him, taking in the flushed, miserable expression he’s wearing.
“What do you need?” he repeats, but this time just as himself.
Nanami scowls at him and when he speaks he acts like every single word causes him great, unbearable agony.
“I want… to be able to see you. I don’t like it this way,” he grunts, and the look he gives Gojo silently dares him to laugh.
Gojo grins but he doesn’t laugh, not at this. He wants Nanami to feel like he can tell him what he wants without worrying he’s going to be mocked. Lovingly teased maybe but not mocked.
Just as quickly as he’d put Nanami on his knees he rolls him over again, still on his knees but this time suspended over Gojo, who lies on his back beneath him. He beams up at Nanami and curls his hands around Nanami’s ass, hiking him up until he’s straddling Gojo’s abdomen.
“Was that so hard?” he chuckles, feeling very pleased with himself when Nanami’s face fills with fresh color.
“I can’t stand you,” Nanami hisses, only to immediately contradict himself by lying down against Gojo’s chest with his face shoved deep into his throat to scent him.
Nanami’s cock is pinned between them now and Gojo can feel him rocking his hips against his belly to stimulate himself, muffling the amused bark of laughter that threatens to escape him. He’s just not used to seeing Nanami so… shameless and needy, and he so very, very much likes it.
“M’gonna get you ready for my knot, Kento… You can come whenever you need to,” Gojo murmurs against his ear before carefully pressing his fingers into the slick crease of Nanami’s ass.
Nanami makes a noise against his throat and lifts his hips slightly, so Gojo takes that as an invitation to brush his fingertips against Nanami’s hole, dripping wet and already soft. He encounters no resistance when he slips a finger into him and realizes, quite belatedly, that Nanami must have fingered himself while he was in the shower earlier, when he noticed that his heat was coming on.
The mental image of Nanami bent over in the shower and fucking himself on his fingers while Gojo was right next door is a powerful one, and Gojo grunts as his cock strains uncomfortably in his pants. He pulls his finger out and replaces it with three, finding the fit a bit more snug this time. He takes a deep breath to gather his fraying sanity and forces himself to go slower, massaging Nanami’s inner walls to coax them into relaxing even as Nanami himself focuses on rutting his cock into Gojo’s belly.
He’s panting wetly against Gojo’s throat with the coat still clutched in his hands and Gojo tips his head to the side to give him more room, muffling a groan when Nanami mouths needily at his scent glands. He’s not in rut and an Alpha’s glands are far less sensitive than an omega’s, but he’s only human and the sensation of Nanami suckling on his throat feels devastatingly good.
“Want you to come one more time before I fuck you, can you do that for me?” he asks breathlessly, wedging his pinkie finger alongside the other three and pressing deep into Nanami.
Gojo doesn’t wait for Nanami to answer. He finds Nanami’s prostate and massages his fingertips against it, twisting his head so he can nudge Nanami away from his throat with his nose and capture his mouth in a rough, searching kiss.
The scent of sandalwood and vanilla is thick and cloying in Gojo’s throat and he clutches Nanami to him, devouring every whimper and gasp of pleasure that escapes him as he comes hard on Gojo’s stomach. Gojo fucks him with his fingers until he’s shaking with overstimulation, then carefully slips them out with a sticky wet squelch that makes Nanami twitch.
He drapes his arm comfortably around Nanami’s waist while the omega drifts for a minute in the brief respite an orgasm will give him from the heat and hormones raging inside of him and brings his hand up to his mouth to lick curiously at the slick soaking it to his wrist. It’s sour and a little salty, and the taste of it fills his sinuses with the overwhelming scent of sandalwood and rose.
Gojo reaches into his pants and fists his cock, muffling a groan against Nanami’s temple when his aching, neglected erection finally gets some much needed attention.
It isn’t long before Nanami is squirming again. Orgasms will help take the edge off, and when an omega is on their own they’ll usually take medication to assist with getting them through their heat, but without that there’s really only one thing that can truly help Nanami right now, and that’s Gojo’s knot.
He rolls them until Nanami is the one on his back again and he looks so ruined that it actually makes Gojo ache just a little. His mouth is red and swollen from sucking on Gojo’s throat and his glassy eyes are brimming with unshed tears, hair plastered to his sticky, sweaty forehead. There’s come smeared on his belly and he’s clinging to Gojo’s jacket like his life depends on it, clearly too far gone to make words at this point.
Gojo curls over the omega and kisses him, soft and sweet, smiling reassuringly at him when he draws back just enough to meet his gaze.
“I’m going to take care of you. Alpha is going to make you feel better,” he croons, nuzzling Nanami’s cheek.
He realizes far too late that he doesn’t have any condoms with him, and he’s quite sure Nanami wouldn’t have packed any either. He could get dressed and quickly run to the store a few streets over, but something about the tremble of Nanami’s hands and the too-brightness of his eyes tells him that under no circumstances can he leave him alone right now, not for even a minute.
They’ll just have to risk it.
His pants and underwear get added to the nest before Gojo positions himself between Nanami’s spread thighs, a pillow shoved under his hips so Gojo has a better angle. The omega’s body is hot and deliciously wet as he slowly sinks into him, growing tighter and tighter when Nanami reflexively clenches around him at the sudden stimulation.
He’s got the jacket pressed to his nose again and his warm hazel eyes are fixed on Gojo’s face, hazy but just focused enough that Gojo knows Nanami recognizes who he is. The scent on his jacket is probably helping keep him grounded and God, Gojo will give him a thousand pieces of clothing if that’s what he wants.
“How’s it feel?” he asks, not expecting much by way of reply.
A low, keening whine answers him and Nanami wraps his legs around Gojo’s hips, silently begging him for more with his body even if words are currently failing him. Gojo tugs them loose and rests them on his shoulders instead, pressing soft, teasing kisses to the delicate pulse of Nanami’s ankle.
Nanami is so wet that when he pulls back the motion is accompanied by a sticky, sloppy sound, and Gojo licks his lips in anticipation.
The omega’s body is like a dream. No beta that Gojo has slept with in the last few years can even come close to the clutch of his ass around Gojo’s cock, or the warmth of his skin beneath his palms. His muscles ripple with each surge of pleasure every time Gojo bottoms out and Gojo allows his eyes to roam the entire length of him, from his flushed, sweaty face, to his wet, swollen mouth, drooling just a little at the corners from when it fell open around a ragged sob and stayed that way.
The parts of his chest that Gojo can see beneath his coat heave with each desperate little gasp of air and the pink buds of his nipples are so tempting that he can feel his mouth watering with the need to taste them. There’ll be plenty of time for that later, though. Maybe Gojo can give Nanami his next orgasm just by using his mouth on his nipples and scent glands.
“You’re the perfect omega,” Gojo snarls breathlessly, drinking in the filthy lewd slap of his hips against Nanami’s ass each time he slams back into him. “So wet, so tight around my cock. M’gonna stuff you so full of come that you’re dripping and then knot you some more, breed you up the way a gorgeous omega like you deserves.”
He drops Nanami’s legs to either side of him and reaches out to grab him, hauling him up until he’s sprawled over his lap with his toes just barely brushing the bed behind Gojo. Supporting Nanami’s weight is easy for someone as strong as Gojo and when he starts to fuck up into him again Nanami chokes, arms flying around Gojo’s shoulders to cling desperately to him.
“Please… Please, Satoru,” Nanami whimpers, and Gojo doesn’t bat an eyelash as Nanami’s fingernails rake deep furrows across his back because the sound of his name spoken like that is oh so sweet.
The new position allows Gojo to get just a little bit deeper than before and he uses this to his advantage, fucking hard into Nanami with a sick, messy squelch of fluids. Slick is dripping onto his thighs and Gojo knows they’re desperately going to need a bath after this but right now all he cares about is the wrecked, needy little sobs of pleasure Nanami is making in his ear and the tight, hot clench of his body around his swelling knot.
He nudges his forehead against his omega’s before kissing him again, hard and deep and claiming. He licks away the saliva on his chin and then tips him back onto the bed, following him down so he can bury his face in the crook of Nanami’s throat.
The scent gland is swollen and raw and Gojo nuzzles against it, fucking his knot into Nanami with a few quick, hard snaps of his hips. He laves the flat of his tongue across the sensitive gland just once, firm but gentle, and Nanami arches off the bed as he comes, clawing desperately at Gojo’s shoulders as the intense pleasure of coming on an Alpha’s knot in heat rockets its way through his body.
The grip around his knot is almost too much but Gojo continues to rock into him anyways, pumping him full of come in thick, hot bursts. He carefully licks over Nanami’s scent gland as he rides out his orgasm, mouthing his way up the proud arch of his throat to kiss away the tears that had finally fallen from his eyes.
He’s absolutely exhausted and Gojo takes extreme caution when carefully rolling them over so Nanami can sprawl on top of him, boneless and trembling after such an overwhelming experience. Gojo extricates the jacket from between their chests and drapes it over Nanami’s shoulders, since their other blankets are currently making up the nest they’re lying in, and waits patiently for him to come back to himself.
It’ll be a while before his knot goes down anyways, and then Gojo can pour this gooey, weak omega into the tub for a much needed bath. It’s Nanami’s first natural heat in years so it’ll probably last for a few days, if Gojo knows anything about anything. He’ll need to call into the school to give them his report on the cursed spirit eventually, and run to the store for food and condoms so his sex talk of knocking Nanami up doesn’t become a reality.
At least… Not yet anyway. He’ll admit though the mental image of Nanami swollen with his child is a tempting one, but that’s something for way, way in the future.
Maybe. All his plans for the future kind of hinge on Nanami wanting any part of that future.
Still, as he feels Nanami tiredly nuzzle his nose into Gojo’s throat to scent him, it’s hard not to get his hopes up.
It turns out he was right that Nanami’s heat would last a few more days. He lies to the school and says he’s forcing Nanami to remain with him in the countryside because they heard rumors of another potential cursed spirit worth investigating.
They stay in the makeshift nest and fuck ceaselessly, and Gojo plies Nanami with bottles of electrolyte drinks and protein bars between orgasms to keep him somewhat fed and hydrated. Nanami gets clingier and clingier the longer his heat drags on, and by the end of it he’s covered in hickeys and completely incapable of standing on his own power, but come to an end it finally does.
Gojo knows he must be tired because he doesn’t voice a single complaint when the Alpha picks him up and instead just tucks his face into the safety of Gojo’s neck. He’s been fairly quiet the last two days, and Gojo would be more nervous about that if Nanami hadn’t spent that entire time refusing to allow Gojo out of his sight for even a second.
He teleports them back to Tokyo in the blink of an eye, arriving in the dark, quiet safety of Nanami’s small apartment.
“I’ll put you in your nest so you can sleep,” He murmurs, dropping their bags to the floor before carrying Nanami down the hallway.
The omega should feel better tomorrow after a much needed undisturbed night of sleep, and it’s the weekend so he’ll at least have a couple days to recover before he has to return to work. He’ll be going on his next assignment without Gojo, after all.
Something ugly and possessive rears its head inside of Gojo’s mind at that and he crushes it ruthlessly before it can put down roots.
Even if Nanami were his omega, he’s earned every right to his rank and his ability to exorcize curses on his own. He doesn’t need a clingy, weak willed Alpha following on his heels the entire time, nor would he want one.
He carefully settles Nanami into his definitely far more impressive nest and sighs, brushing his bangs back from his forehead so he can drop a kiss to it before realizing that it may be an unwelcome gesture now that Nanami isn’t in heat. If he dislikes it though he doesn’t say anything about it, watching him silently with exhaustion bruised eyes.
He’s wearing one of Gojo’s sweatshirts and Gojo realizes he’s probably never going to get it back by the way Nanami tucks his hands into the over long sleeves before he curls up in his nest.
“I’ll, um… I’ll leave you to it then. Call me if you need anything?” he offers uncertainly, somewhat appeased when Nanami nods absentmindedly.
His eyes are already closed and it’s clear that the comfort of being back in his own nest in his own home is already pulling him closer and closer to unconsciousness. Gojo is about to turn to leave when something in the nest catches his attention.
It’s one of Gojo’s uniform jackets. The same kind that Nanami had spent his entire heat with pressed against his face. He must have stolen it at some point and ferreted it away into his nest when Gojo hadn’t noticed.
Not in the past few weeks though. Before that, probably before he quit the world of sorcerery and ran away to that cushy office job of his. He wonders what else of his he’ll find if he digs a little deeper.
He can’t imagine his scent is still on it though after all this time, so without thinking he strips off the jacket he’s currently wearing and drapes it over the half asleep omega, nearly vibrating out of his skin when Nanami hums happily and immediately tucks his face into the fabric.
It’s on now. It’s so on.
Gojo can tease Nanami about stealing his clothes another day but for now he just leans down and presses another, far more confident kiss to Nanami’s temple. The sweet, warm scent of sandalwood and rose fills his lungs.
“Sleep well, Kento.”
