Work Text:
For the last couple of weeks, there had been a real pep in Gojo’s step. Everyone noticed. A few had even passed comment or questioned it, to which he had simply shrugged with a smile and said:
“Just having a good day!”
Ever since he and Nanami had started dating officially, they decided to keep it a secret for a little while, just to give them time to figure everything out. Well, as much as they possibly could, since life loves to throw curveballs.
Making it official was just a mere formality to them, as they were every bit the real couple by the time it happened. Gojo had a drawer of clothes in Nanami’s bedroom, spare shoes in the entryway rack, and a couple of little figurines had snuck their way onto his bookshelves.
Likewise, Nanami had half a rail of spare shirts in Gojo’s place at the school, a box of old band t-shirts under the bed and a bunch of his high school CD’s on Gojo’s own bookshelves, making a home for them next to Gojo’s pink Hello Kitty CD player.
It had, unfortunately, been almost a week since they had seen each other last, what with their schedules not quite aligning properly - one of aforementioned curveballs - and Gojo had been going crazy.
Nanami was due home the next day, Saturday, and while it had taken some finagling, Gojo had managed to clear both of their schedules ahead of time.
He checked the time, pulling his phone out to no new notifications from Nanami. Which didn’t surprise him, since he was working his last mission of the week some three hours away. He had spent the week dismantling a ring of curse users committing heinous acts throughout the city.
What did surprise him, however, was the growing crowd of people in the middle of the street, ooh-ing and aah-ing at something just out of Gojo’s line of sight.
It was quite bothersome, as the road was usually empty, and made for Gojo’s favourite walking route when he had time to simply meander and enjoy the scenery.
A heavy thud from the middle of the circle brought out a collective grimace from the gathering, and heavy footsteps sounded as a man dressed all in black broke through the slowly dispersing spectators. He looked over his shoulder, guilty, scared, his face practically smashed in as a giant centipede-like shikigami wound its way up his arm and under his sleeve.
A curse user.
Gojo’s eyes narrowed and he took off in pursuit, quickly cornering the scared and beaten man in an alleyway.
“PLEASE! I didn’t want to use this on him, but he was really strong and I panicked! The effects will wear off in a couple days, I swear!”
The man had trouble speaking through the terrified snot and tears and swelling covering his face.
“What effects?” Gojo demanded, standing strong above the cowering mess, his voice as cold and sharp as his eyes.
“This little lady here has an aphroditic venom, once her victim ingests it, they’ll go into a frenzy.” He cleared his throat, showing off the arm-sized curse. “They’ll lose control of their body, have no inhibitions and get really really… Uhm… You know. But it disappears entirely once you… Uhm.. You know. He trailed off, his cheeks pinkening.
Gojo could gather.
“Who did your ‘little lady’ spray?” He said, lowering his blindfold just enough to scare the little termite straight.
The man squealed like a pig, covering his head with his arms.
“Another sorcerer?!” He shrieked, shuffling backwards until his back hit the wall.
Gojo held up one hand, fingers slowly shifting to form one of his signals.
“That big guy on the street! He’s been chasing my buddies and I all week, hunting us down like a maniac! That blonde one!”
At his description, Gojo’s blood turned to ice in his veins.
Nanami.
He hadn’t even taken the time to see the victim of the attack, instead going into overdrive to hunt down the culprit before any more damage could be done.
Gojo swore, rage ignited in his veins and he left the alley faster than he arrived, the curse user’s cartoonish scream of terror and agony echoing throughout the walls behind him.
He made it back to the scene of the attack, only to find a blood-stained leopard print tie on the ground. Clenching his jaw in frustration and upset, Gojo grabbed the tie, trying to rationalise that the blood belonged to the beaten up curse user, and not the tie’s owner.
He scanned the area, raising a veil before letting himself rise off the ground, finding minute comfort in embracing his immense cursed energy.
From the air, he could try and locate cursed energy signatures better, scanning and searching for that one that comforted him the most.
Interrupting his search, Gojo’s phone rang, obnoxious in its melody and volume.
It was Nanami.
“Kento! Are you alright?!” Gojo cried down the phone.
“Get down from there you idiot, someone will see you.” Came the droll reply, sounding only ever so slightly out of breath. Stunned, Gojo did as he was told, floating gently back down to earth. But not before locating Nanami’s cursed energy signature and tracing him to behind a big tree just in front of the school campus barrier.
“Are you alright?!” He said, rushing over to where Nanami was leaning bodily against the trunk, undoing the top buttons of his shirt and panting slightly.
Upon hearing Gojo’s voice, Nanami glanced up, locking eyes with him before his entire face crumpled and he bent over double, clutching his lower stomach.
“Fuck!” He yelled, dropping to his knees and groaning in discomfort.
Gojo followed him down, rubbing his back and petting his hair.
“Please.” Nanami begged, his words muffled by his arms as he curled in on himself.
“Anything, baby, what do you need?”
He stayed rubbing Nanami’s back, praying it was giving him at least a modicum of comfort. Time passed by like a warm treacle, slugging over them slowly, unhurried and blocking out the cold.
“I’m right here, just tell me what you need.”
Nanami uncurled and immediately slouched with his back against the tree trunk. His hair was disheveled, falling across his face, which was flushed pink and dusted in a thin layer of sweat. His pretty eyes were glassy and unfocused, eyelids heavy and blinking. And perhaps the most damning evidence of all that the curse user was not lying, the straining bulge in the front of his slacks.
“You.” He said, his voice already half gone. “I need you, Satoru. Take me home.”
And Gojo had to do just that. The problem was Nanami lived a 20-minute drive from campus, and dragging him through school grounds to get to Gojo’s place with him in his current state wasn’t an option.
Gojo was too scared to warp them, unsure how the normal strain on his body would react with the curse’s venom.
Ijichi or any of the other managers were absolutely out of the question too, as Nanami would kill him for letting anyone they knew see him in that state.
So to the taxi rank they went.
Thankfully, Gojo was wearing a slightly baggier uniform jacket, and plopped it over Nanami to hide some of the more damning evidence of his current affliction as he led him, jelly legged and clingy to the nearest rank.
“Satoru.” Nanami whined in a voice so unlike himself as he pawed at Gojo’s chest and ass and quickly hardening cock - anywhere he could get those wandering hands on.
Gojo grabbed his wrists after one hand got a bit too bold for broad daylight, holding them behind his back in an awkward sort of embrace. Nanami hummed at that, rolling his shoulders back as if presenting.
Gojo made a strained noise in the back of his throat as a car drove up, hailing it down and bundling them both in the back seat.
He gave the driver Nanami’s address and slipped him the biggest bill that was in his wallet to get them there as fast as possible. The man accepted it yet did not move, his eyes fixed on Nanami in the back seat.
”Is that your cologne?” He asked, sniffing the air.
Nanami shrugged. “Is it smokey?”
The driver shook his head.
“Then it’s his.” Nanami said, pointing his head at Gojo.
The driver’s eyes barely flickered to Gojo.
“Is that your natural hair colour?” Nanami nodded, a small smile on his face.
“It’s beautiful. Really. I’ve never seen a man like you before.”
Nanami preened at the praise, blossoming under it and Gojo cleared his throat obnoxiously.
“I just bribed you to speed us home and yet you’ve not even moved. Can we get going please? My husband and I have a long night ahead of us.” He snapped, wrapping his arm around Nanami’s waist and sliding him across the middle seat into his side where he sighed in content and shifted to bury his face in Gojo’s neck, nipping and kissing a line up to his jaw.
Gojo held eye contact with the driver in the mirror until he lost his nerve and finally started to drive.
“You’re jealous.” Nanami whispered in his ear.
“You were flirting with him.” Gojo grit back, the effect ruined slightly by the gentle moan that slipped out with his words as Nanami continued his ministrations on his neck, one hand creeping up his inner thigh.
“Maybe you should fuck some manners into me, Husband.”
The rest of the drive consisted of the longest 15 minutes of Gojo’s entire life. Catching the drivers’ eye in the mirror every so often as Nanami practically made out with his neck, hand working over the bulge in Gojo’s uniform slacks all the while.
Gojo was so worked up by the time they got to Nanami’s apartment he had no idea what to do with himself. But he didn’t have to think for long, as the second the door clicked shut, he was thrown back against it and his trousers and underwear were yanked down in one unforgiving move.
Nanami dropped to his knees with a resounding thud that would absolutely hurt later once the venom wore off. With a longing smile on his face, Nanami wrapped his hand around Gojo’s cock, opening his mouth and letting gathered drool spill onto the length of it. He used his spit to slick the rest of Gojo’s cock before taking him in his mouth as deep as his throat would allow.
Gojo shouted, his hands flying to Nanami’s hair as he hollowed his cheeks and started to suck him off with desperation. Gojo let out a noise that would have absolutely embarrassed a less shameless man. But shame was one of the only things Gojo was lacking in, and he was getting his dick sucked by the love of his life.
Nanami settled into a rhythm, working Gojo deeper and deeper into his throat with every pass of his mouth, underscored by all sorts of wet, vulgar noises.
“Oh god, Kento, please slow down.” He begged, already far too close to the edge to be of any help to his afflicted partner.
Nanami pulled off with a wet pop and shook his head.
“Come in my mouth, Satoru.”
Was all he said before sinking back down, swallowing around him to deepthroat him just the way he knew he liked. Gojo’s hips started to twitch with the urge to thrust into his hot mouth. Nanami moaned around him, freeing his own cock from his slacks, pumping in time to his throat working.
Gojo’s cock twitched in his mouth and he hummed in excitement as Gojo’s grip tightened on his hair, thrusting once, twice into his mouth before spilling his load deep down his throat.
“Fuck, Kento.” He said, pulling back and slipping out of his mouth, relaxing against the door and catching his breath. Nanami stood on shaky legs, opening his mouth to show the leftover come on his tongue before making a show of swallowing it down.
“Use your RCT.” He commanded, slipping his trousers off and kicking them away.
“It’s so hot, Satoru, come on.” He complained, turning on his heel and leading him weakly through to his bedroom.
Obeying diligently, Gojo took a deep breath and followed, his cock practically springing back to life at the thought of Nanami waiting for him.
When Gojo entered the bedroom, he was floored at the sight. No RCT needed this round, his body was working in perfect tandem with his thoughts. Nanami was face down, rutting furiously against a pillow with two lube-slick fingers plunging in and out of his own hole.
“Stop.” Gojo demanded, all traces of humour gone from his voice.
Miraculously, Nanami obeyed, his sweat-slick body trembling with the effort.
“Good. That’s my job.” He said, crawling up the bed to him and sliding his hands underneath him, grabbing either side of his shirt and pulling, hearing the fabric rip from beneath him and the light tinkling of the buttons hitting the floor.
“Satoru!” Nanami barked, stuck between being irritated at the senseless waste of a good shirt and absolutely out of his mind with arousal.
It was as if a fog had descended on him, he wasn’t seeing or thinking clearly, his mind held hostage by the carnal instincts of his body. His skin was feverish and sweaty, his body trembled more with each second he went unsatisfied and it was as if there was a parasite in his mind, consuming all thoughts and rationality, hollowing him out until all he could think about was how badly his body craved release, how tight the coil was wound inside him. Unable to think of anything other than being filled, being taken.
When Gojo’s fingers found his wet hole, his whole body collapsed boneless onto the mattress, finally getting what it had been craving.
“You’re so relaxed I don’t even know if you need any prep.” Gojo laughed, bending over him and kissing his neck. Nanami groaned, feeling Gojo’s cock slotted between his ass cheeks but not where he desperately needed it.
“You need it so bad, don’t you?” Gojo cooed.
Nanami nodded, tears pricking in his eyes as his legs thumped against the mattress in frustration.
“Maybe you should go back and ask that taxi driver then.” Gojo laughed darkly, pulling back from him.
“No!” Nanami cried, hands darting back and grabbing hold of Gojo’s wrist before he could fully leave. “Please, no.”
He reluctantly let go of Gojo’s hand just long enough to push his hips up, back arching off the bed as he did the only thing his mind supplied in order to stop Gojo leaving: presented himself.
With the hand that was on Gojo’s wrist, he reached back and grabbed hold of one of the globes of his ass, pulling it to the side and spreading himself open.
Normally, this level of debauchery would have him cringing at the prospect, he’d never been one to beg or whine or spread his own ass for someone’s attention. But judging by the sheer desperation in Gojo’s eyes, the craving, the longing, the absolute hunger in those glacial blues, he might have to do it more often.
Gojo didn’t even try to hold back his impulses, leaning down and biting a dark mark into the plump flesh of Nanami’s ass before spitting once onto his already wet hole, just to watch his body twitch and tremble with need. His cock hung dark and angry and leaking profusely onto the sheets from where his hips were held high and Gojo took pity on him.
He sat up straight, fisted his cock twice and lined himself up, wasting no time in pushing into Nanami’s feverishly warm body.
Twin groans filled the air as Gojo slowly bottomed out.
“Good?” He asked, rubbing Nanami’s lower back as his hips pressed flush to Nanami’s ass.
Nanami nodded, his words garbled and meaningless already, his eyes glazed over with need.
Still, Gojo knew his lover, and trusted them both to know and find the limits. So when he started thrusting at a borderline violent pace, he knew Nanami was strong enough to not only take it, but enjoy it in his venom induced frenzy.
Nanami’s mouth hung uselessly open, whimpers and moans and cries wrung out of him with every thrust.
Gojo grabbed Nanami’s hips like handlebars, pushing and pulling him back and forth as he fucked in and out at a blinding pace. His body was hot, warmer than usual around him and as he angled his hips to hit that sweet spot within him, he could’ve sworn he felt even tighter than usual.
Beneath him, Nanami shook violently, tears spilling from his eyes and drool from his mouth. His cock bounced between them, leaking like a faucet onto the sheets. His whole body shook and he let out a winded cry as Gojo began nailing his prostate with every thrust.
His hands scrabbled for purchase and he was only slightly aware of his orgasm building before it hit him like a truck.
“Satoru!” He cried, before his whole body convulsed, pleasure overloading his veins as he came profusely, spilling all over the bed and his own stomach.
Gojo fucked him through it, his hips never once losing rhythm as he mumbled praise and sweet nothings.
To Nanami’s horror, even after an orgasm as powerful as that one, his cock was still hard, and the effects of the venom showed no signs of stopping or slowing down.
Much like Gojo’s thrusts.
“Shit, Kento, I love it when you come untouched. You’re so good for me.” He grinned, picking up the pace even further.
Nanami was like a ragdoll in his hands, strong and firm around his hips as he dragged him forwards then right back onto his cock again. He screwed his eyes shut to cope with the additional sensation. His body went limp, cheek squished against the pillow as Gojo planted one foot on the mattress for more control, taking his pleasure from Nanami’s body.
He continued like that for a while before a second orgasm crept up on Nanami. Gojo grinned, releasing his vice grip on Nanami’s hip to reach between his legs and stroke his cock.
Again, Nanami cried out, body convulsing and vision whiting out once again as he came for the second time that night, his nerves alight with pleasure that showed no signs of stopping.
They fucked for hours. The shikigami’s venom staying in Nanami’s system past sundown and almost through until sunrise again. Nanami came three times on his knees while Gojo fucked into him, only resting once Gojo himself came. He finished deep inside Nanami before doing exactly what was requested of him earlier, breathing easy and channeling positive energy to use RCT on himself.
Then Nanami found himself flipped over and folded in half, knees beside his ears as Gojo wrung another couple of orgasms out of them both before calling a break and cleaning them up in the shower.
Which, of course, led to Nanami pressed against the tiles as Gojo fucked him from behind again.
What started out as Gojo taking care of Nanami, doing what he needed (and wanted) to do to help him through the effects of the venom, like most things turned into him simply showing off.
Nanami took it as a good sign that he was now lucid enough to read the numbers on the clock on the bedside table, and a bad sign that it was already 3:35am, a whopping 13 hours since they had started.
His entire body ached, his cock sensitive and wrung out after countless curse-enabled orgasms with no refractory period and still Gojo plowed into him, hands back on his hips again.
“Fuck, Kento, you’re still so tight for me. You’re taking me so well.” He moaned behind him, barely a hair out of place. His voice was measured too, like he had gone for a light jog, not marathon sex.
“Are you close?” Nanami asked, practically begging for relief from the overwhelming onslaught.
“Yeah baby, I’m gonna fill you up.”
Nanami tightened weakly around him, faltering his jackrabbit hips. After teetering on the knife edge for so long, Nanami finally came for the last time that night, his body so barren his cock twitched and jumped, but nothing came out. A dry orgasm.
Gojo had no such problem, slamming home one last time and filling him up again, his cock spurting copious amounts of cum deep into Nanami.
The white haired beast of a man bent down over Nanami, his tight abs sliding against Nanami’s sweaty corded back as he mouthed at his ear and kissed his hair. His soft cock slipped out of Nanami with a squelching noise that non-venom Nanami wasn’t able to hide a grimace at.
“One minute, babe, I’ll use RCT and we can go again.”
With Herculean strength he didn’t realise he still possessed after that marathon, Nanami flipped them over, pinning Gojo to the mattress. His chest heaved and his muscles trembled with exertion.
“NO!” He cried, exhaustion set in the lines in his face, the bags under his eyes. “Dear god no more. I’m okay now, thank you for helping me.” He begged, knowing full well Gojo didn’t do all of that purely for his benefit. As evidenced by the licentious drip of cum pouring from of his fucked out hole into Gojo’s hips that would have made him die inside if he was any more awake.
Gojo studied his face, looking far more alert and Nanami-like despite the fatigue. He gave a big grin before tackling Nanami and flipping them onto their sides, bringing him in for a tight hug.
“You’re back!” He pressed kisses all over his face and laughed when the fake irritation made way for a genuine gentle laugh.
“I’m back.” Nanami smiled, his eyes closing.
“Do you want food? I have leftovers. I was gonna heat them up so we could order fresh stuff when you got back. But you got back early so as long as you don’t mind-”
Gojo trailed off, glancing down at Nanami, who had begun to snore lightly, overcome by sleep. Gojo smiled, brushing the hair out of his face gently, before cuddling in and joining him.
When Nanami awoke not even four hours later by the alarm he had forgotten to turn off, he wasn’t surprised to see Gojo already awake and watching him.
He turned the alarm off and launched his phone into the laundry hamper in frustration. Every inch of his body was screaming in pain, his muscles ached and his skin was crying out for a good shower and maybe even a massage.
Gojo chuckled and kissed him good morning, thumbing over the creases between his angry furrowed eyebrows.
“Hey, you didn’t kill that curse user, did you?” Nanami asked, voice as smooth as sandpaper.
Gojo shook his head, pouting slightly.
“No, why?”
A menacing grin overtook Nanami’s face as a plot began to form in his mind.
“I think you ought to pay him a visit next time.”
