Work Text:
Kento should have taken this into account, should have seen it coming but things didn’t always go his way and that much already annoyed him and now he’s standing in the middle of the road, well it was supposed to be a road but now it’s a room. Kento’s still trying to wrap his head around it, the room had manifested on its own. It doesn’t seem nor did it feel like a domain expansion.
He had knocked on the side, had tried to slice through it but nothing happened. He tried all possibilities, even had Itadori try to force his way out with brute impact but nothing. It’s all too annoying, Kento definitely didn’t want to work overtime and time’s only ticking and he has a teenager desperately clinging to him—
“—Itadori-kun, please don’t make it any harder than it needs to be,” Kento says, and that only seems to dampen Itadori’s mood because the boy’s hanging his head low. Kento’s fingers itching to ruffle the boy’s head but it is all inappropriate.
This. Is. All. Too. Inappropriate.
Itadori should not be grinding against Kento’s thighs like this, should not be looking at Kento with that lustful expression on his face, should not be clinging to Kento whatsoever yet here they were. Standing in the middle of a fake room with Itadori desperately rutting his hips against Kento’s sides (and honestly, Kento should shove him away but he doesn’t have the ‘heart’ to do it). But at least, Kento’s a responsible adult, he will not lay his hands on a child, and is not planning to do it even if Itadori does become of age—how the fuck did his mind wander off there, Kento dissolves the thoughts as quickly as possible.
This is all too weird, having Itadori doing this (a part of Kento reminds him that this is not Itadori’s fault at all), Kento will not let his moral compass break because of this small incident, and maybe that’s exactly the reason why Kento despises Gojo so much. The older man lacked a moral compass, Gojo’s a screwed person and somehow their dislike for each other is mutual, with Gojo claiming that Kento had too much.
“Please, Nanamin?” Itadori pleads, shaking a little, cheeks flush red and Nanami knows it’s only a matter of time before the boy starts to lose control, whatever had infected Itadori was working fast, way too fucking fast and soon his head will become too overwhelmed with wanton need for release—fuck, this is all Kento’s fault for not supervising carefully.
They’re stuck in this room until either Gojo, himself, comes to rescue them, or they actually go through with the stupid curse’s instructions which is to fuck Itadori until the damn cursed spirit is satisfied enough to release them. And Kento will not fucking do it, he definitely will not lay a hand on a child.
“Nanamin,” Itadori whimpers.
Kento releases a heavy sigh, fixing his glasses (not that they needed any fixing but Kento really needed some distraction so his eyes wouldn’t wander down to the growing erection belonging to a certain intoxicated Itadori).
“No, Itadori-kun, I will not touch you when you are not in the right state of mind.”
That only seem to set Itadori off because he’s pushing Kento onto the bed, the older man flopping onto the soft mattress before the pink haired boy’s climbing over him and Kento really doesn’t have the heart to shove him off. God forbid, he ends up harming Itadori, he would never forgive himself.
“Nanamin, please, I’m here, I’m saying yes. Please touch me,” Itadori begs, grabbing one of Kento’s larger hand to place above his crotch and Kento can feel his ears start to burn at the wetness he feels underneath his hand. “Please? It hurts so much. A-and, there’s no guaranteeing Gojo-sensei will get to us...”
It makes sense.
Kento’s moral compass is starting to spin on itself. He doesn’t want to do this, but he also doesn’t want Itadori to suffer through this all alone. The best compromise he can come up with is to just give Itadori some handjob. He’s definitely not going to any further than that (just so he can save a little bit of his sanity).
Itadori’s a cute boy, cheerful and bright, always so eager to please.
Kento can only refuse him for so long but when Itadori’s sitting above him, looking flush from head to touch, the boy presents an exquisite picture—not that Kento’s going to admit it out loud. Before Kento can even make any decisions, Itadori’s grinding down on top of Kento’s crotch, a startle moan escaping his lip which only seems to encourage Itadori as he moves his hips a little harder and a little faster. Kento wraps a shaky hand around Itadori’s arm.
Much to his embarrassment, Kento’s also sporting an erection, little wet spots forming and staining his pants. Lord, he really hopes Gojo doesn’t try to come and rescue them. He’d rather not have anyone see him like this.
“Nanamin!” Itadori whines, and Kento’s eyes darts back up to Itadori’s pretty flush face, it’s clear whatever shit that curse spirit had toss at Itadori is finally working and soon Kento will have a fuming and overly sex-driven Itadori on his hand. “Please, do something!”
A lump forms in Kento’s throat, it really is the now or never moment. He’ll have to do it at this point. He’ll do it to help Itadori and he’s only going to do it to help Itadori and nothing else.
“Yeah. Just,” Kento stumbles over his words, flipping them over so that Itadori’s underneath Kento now, the small boy watching every single movement with a hungry glint in his eyes. Kento’s fingers working diligently to remove his glasses, and jacket. He neatly folds it, tossing it onto the chair beside the bed. It’s oddly weird how this mysterious room resembles a motel room—Kento tosses that information to the side, focusing on the fussy teenager he has underneath him.
Kento works hard trying to remove Itadori’s uniform, the pink haired boy’s already panting and shuddering with each touch. The skin radiates an intense amount of heat, so warm that Kento really wants nothing more than to trace every inch of Itadori’s skin but he refrains from doing so.
Just make the kid cum, and hopefully satisfy the cursed spirit enough to be able to escape from here. The instructions didn’t specifically say what they needed to do, just that a state of orgasm must be reached or at least, that’s the conclusion Kento came up with.
“Nanamin,” Itadori moans out when he’s fully bare before Kento, only his red briefs are hanging wet against his crotch and Kento gulps, trying to rationalize this whole situation inside his mind, that this is nothing but a simple procedure to help elevate the pain Itadori’s feeling. "It hurts…”
“Itadori-kun, don’t worry. I’ll help you,” Kento says, voice straining as his fingers reach for the band of Itadori’s briefs, pulling down the material to reveal Itadori’s painful erection. The shape is surprisingly cute, and average, if Kento’s going to estimate, probably around six or maybe seven inches.
It’s twitching and throbbing so painfully, the tip overflowing with precum and the colour is a healthy one although he spots some blue hue.
Almost by instinct, Kento works to capture the hot flesh in his hand, wrapping his hand around at the tip to smear some of the precum in order to make each stroke and glide against Itadori’s cock easier for Itadori. Much to his surprise, just that one touch alone is enough to push Itadori over the edge, the small boy cumming right inside Kento’s hand, the hot spurt of cum covering his entire hand.
Itadori sobs, tears clamping his lashes together as he embarrassingly apologizes. “I—I’m sorry…”
Kento almost wants to chuckle (but restrains himself, now’s not the time), still his hands doesn’t stop moving, each stroke is slow, not moving too fast, knowing just how sensitive Itadori is at this moment. And as if to confirm his suspicion, Kento offers one stroke, Itadori reacting almost immediately, his body’s shaking. Itadori’s mouth falling open as he chants out broken ‘no’s’ under his breath, fingers digging into Kento’s wrist.
“I-I’m too s-sensitive, N-Nanamin,” Itadori cries out, his body jerking and jolting in a failed attempt to get away from Kento’s hand.
“It’s okay, Itadori-kun,” Kento says, eyes dilating as he watches the pink haired boy just break down under his touch. His moans sweeping through the room like an angelic choir, his body pliable under Kento’s administrations. “The faster we get this done, the faster we get to leave. Trust me on this.”
That only causes Itadori to sob, the denials from earlier stopping altogether and Kento’s sure that Itadori’s mind is probably growing hazy from the amount of pleasure he’s being hit with, both from Kento stroking his cock to the pollen he had consumed. Technically, Kento should have allowed Itadori to rest up but the longer they stayed in here, the higher the chances of getting discovered in this rather, compromising situation, and Kento really doesn’t need Gojo to know about this.
“O-okay, I-I trust y-you,” Itadori says in a breathless tone.
Kento grits his teeth, Itadori’s really testing his patience here right now, and Kento doesn’t know how much longer he can push this off—in fact, he’s not even sure why he’s trying to push this off. Isn’t it better to just fuck Itadori once and get this over with?
The faster he fucked Itadori, the faster they can get out of this place (Kento’s planning to keep this portion of their mission a secret, he really doesn’t need anyone to know about this).
“Okay, Itadori-kun, I need you to understand that what we’re about to do is a crime in the eyes of the law—”
“—please, N-Nanamin, it hurts,” Yuuji sobs out, trying to pull Kento down for a kiss and the older man’s really struggling to keep it together.
With the little bit of strength he has left, Kento’s keeping the rosy cheeks boy at arms’ length. Clearing his throat, Kento can feel his own cheeks heat up from having a teenager hump and grind and just beg for his attention. “Itadori-kun, are you coherent?”
Itadori slowly blinks his hazy eyes, whining softly, his skin shining in the thin layer of sweat.
“Itadori-kun, I will not do anything unless I hear you consent to this,” Kento says (a small part of him doubts his words. But he can try).
“Yes, yes, oh god, yes, Nanamin, please, just do something,” Yuuji pleads, and that’s the only thing Kento really needs to hear before he loosens the grip he has on Yuuji, the smaller boy tugging Kento down for a kiss. The pink haired boy’s rubbing their lips together, in a teasing way, his hot breath fanning Kento’s face (that little bit of patience finally snapping for Kento), Kento’s fingers curls around to deepen their kiss, it’s all too much tongues—like Itadori’s searching for some type of relief which they both knew wouldn’t be coming until much much later when Kento’s balls deep inside the intoxicated teenager.
“Nanamin, Nanamin…!”
Kento groans, his fingers sliding down to tug on Itadori’s erection, the smaller boy’s just lying there, openly naked and watching Kento’s every movement with sultry lust filled eyes. Kento runs the palm of his hand down Itadori’s sides (the heat radiating hot and high), his hands groping the flesh before it fully cups Itadori’s surprisingly well endowed ass. Dipping a little lower, Kento’s surprise to feel an insane amount of wetness there, mind reeling a little as he pushes one finger—Kento groans.
Itadori shudders, mouth falling open as he pants low, “M-more, please…you c-can add m-more.”
Kento shakes his head, he wanted to take his time, knowing that this can possibly be Itadori’s first time. There’s nothing wrong here, well other than the fact he’s about to fuck a minor but it’s for good reasons other than that, there’s nothing wrong. Except for the fact that Itadori’s somehow…producing some type of slick in his ass. Like someone had poured some lube in there prior to this…very unfortunate situation.
The blond man traces around Itadori’s rim, even if there’s copious amount of slick, Kento still wants to take the extra precaution, his eyes darting back and forth from Itadori’s ass to Itadori’s face to ensure that the smaller boy wasn’t showing any signs of pain.
Then, Kento allows his finger to sink into Itadori’s heat, internally groaning as Itadori’s walls immediately clamps down on him. Spasming and squeezing his forefinger, Itadori makes quite the picture underneath Kento, writhing with just one finger, his pretty pink cock bobbing against the flat expanse of his stomach—it’s all too erotic and hot and Kento…he’s really struggling, trying to ignore the tent forming in his pants.
Gently, Kento introduces a second finger, and Itadori’s hole just seems to eagerly open up to him and it’s not long before two fingers became three and soon Itadori’s stomach’s covered with more cum and the smaller boy’s sobbing, begging and pleading for Kento to just fuck him already.
Kento nervously swallows down the lump in his throat, his fingers (both the clean and slick covered) working to tug his own pants and boxers off. Itadori’s whining like a cat in heat, his own fingers pinching and tweaking at his nipples—and fuck, Kento desperately wants to snap a picture but he’s not Gojo, so he’s not going to do it.
“Nanamin, Nanamin, please, i-it hurts,” Itadori cries out.
“Shh,” Kento whispers, “don’t be impatient, Itadori-kun. I need to make sure we go through all the steps.”
That only seem to make Itadori whine even more, and it’s adorable, if Kento’s being honest. The older man gently strokes his cock to full length before he flips Itadori around so he’s on all fours. Kento guides the head of his cock to Itadori’s winking entrance, the smaller boy rutting his hips back, it momentarily catches Kento’s cock.
A little annoyed, Kento’s hand moved faster than his mind could process it, the resonating sound of skin against skin echoed in the room, Kento’s right hand is tingling and his eyes land on the light imprint on Itadori right asscheek—fuck, he just spanked Itadori.
“I-I…!” Itadori cries out, shaking but the small boy’s keeping his hips as still as possible. “S-sorry.”
A shiver runs up Kento’s spine, he has to bite down on his bottom lip to stop himself from groaning out loud and he’s glad he flipped Itadori over because he really did not need Itadori to see the effect he has on him. The pink haired boy really has Kento wrapped around his pinky (it pisses him off that Gojo’s right).
“Don’t move without my permission, Itadori-kun, what if you got hurt?” Kento asks, rolling his hips gently until the head of his cock is kissing Itadori’s entrance once again, then he nudges his hip forward a little, being met with little to no resistance at all. “Don’t move. I’ll do all the work, understand?”
Itadori keens, and Kento lands another hit on Itadori’s left asscheek (Kento’s really hoping that Itadori won’t remember much of what happened in this room).
“Y-yes…sir!”
Kento groans at Itadori’s response, rocking his hips back and forth, and with each rock forward, he pushes in another inch until finally, he’s balls deep. Itadori’s walls spasming around his cock, it feels too good, almost like he could just cum like this but he doesn’t. Kento won’t cum just like this, he refuses to cum before Itadori because he’s not here for his pleasure, they’re both here to get out of this damn place and get Itadori treated ASAP.
Itadori squirms around on the bed, and Kento really has to grit down on his teeth to stop the noise from escaping his lip. Struggling a little, Kento asks, “are you ready?”
The pink haired boy offers a small nod, Kento tightens the grip around Itadori's waist, staring at the back of Itadori’s head before he starts dragging out his hips until only the head of his cock is caught at the entrance, his thumbs hooking in between Itadori's ass cheeks to spread the flesh apart so he can eye the way Itadori's lewd hole flutters preciously around Kento's cock. Working so hard to accommodate Kento's girth. Itadori’s lewd hole keeps trying to suck him back in. It’s so obsence and erotic and sexy and—
—he must have been staring at Itadori’s hole for a while because the smaller boy’s glancing over his shoulder, body trembling in an attempt to keep himself upright. “N-Nanamin?”
Kento snaps his hip back in one go, forcing a breathless moan out of Itadori’s chest. Kento doesn’t even need any acknowledgement from Itadori to know that Itadori’s cumming once again. The pool of cum underneath him is growing bigger and bigger with every thrust (Kento’s not sure if it’s precum or literally cum but either way, Itadori’s cock’s acting like a leaky faucet).
“N-Nanamin, I-I can’t…!” Itadori sobs out, burying his face into his arms. “I-it’s too much…!”
“No, you can take it,” Kento reassures the pink haired boy beneath him, he’s not sure if he’s saying it for himself or for Itadori. Kento shifts his hip, changing the angle, each movement becoming more and more erratic until a heat in his stomach starts to blossom, the knot growing bigger and bigger until Kento’s gripping at Itadori’s hips hard enough to leave behind small bruises, and it only takes one more snap of his hip before Kento’s burying himself as deep as possible.
The knot snapping in full force and then he’s spurting inside—cumming inside Itadori, the smaller boy shuddering, back arching into a perfect bow as Kento continues to fill him up, Itadori’s mouth falling open to chant Kento’s name—Nanamin—a nickname that Kento didn’t dislike at all (only if Itadori’s the one calling him that, of course).
“Itadori-kun?” Kento whispers, tugging his softening cock out of Itadori’s hole. He gently turns Itadori over to make sure the smaller boy didn’t suffocate or anything. Gulping lightly, Kento’s surprised to see the bliss expression on Itadori’s face, rosy cheeks, and dilated eyes. Kento’s eyes zoning in on Itadori’s cock, the hot flesh’s still fucking hard.
“Are you…o—”
Itadori shakes his head, eyes growing glossy as he wraps his hand around Kento’s wrist, bringing Kento’s hand down to his throbbing cock, coyly blinking his eyes as he whispers, “M-more, please, sir, please Nanamin?”
Kento closes his eyes, fuck it all. If Gojo ends up seeing them like this, well, he could really care less. He’s just hoping he’ll finish before 7 pm today (he also isn’t looking forward to explaining to the higher ups why exactly Itadori’s out of commission).
