Work Text:

“C’mon, say it.” 

You grit your teeth, nails scraping against the grain of his desk. 

For someone who’s supposedly omnipotent and loaded with enough money to fund the colonization of a whole new planet, the asshole happens to still have a cubicle. 

He can’t do anything about it, really, considering that most Japanese schools have the faculty share one massive space. If Yaga had his own office, you know for a fact that this dickhead would have figured a way to take over that. 

Alas, the principal also shares the same large room with the other teachers. So the one and only Gojo Satoru has to learn what it means to share a space with everyone else, and clearly – 

“Goddamn it, Gojo–” You curse, trying to push yourself up from the table. 

That proves to be fruitless when he slams the side of your head back down onto the surface with a full thud, your jaw clenched in frustration. 

“I’m going to kill you–” 

clearly , he has no qualms about visually sharing you with any faculty member by fucking you in the shared office. 

Just visually, though. Gojo has been raised from birth to be selfish, and he’s not about to let anyone else hit it off with you. He doesn’t give a fuck if it’s Ijichi or even his dear friend Shoko. 

Equal rights, equal fights. 

A reedy noise escapes you when you feel three of his lengthy fingers push into your cunt. His other hand smoothes up and over the swell of your ass, then presses down onto the small of your back. It secures your position on the desk even further, keeping you from squirming away from him as he knocks your feet further apart, just like how he enjoys it. 

Just like how you enjoy it. 

You let out a huff when his fingers curl downwards, rubbing in come-hither motions against that spongy spot in you. Unintentionally, your muscles clench and squeeze around him, body taut and tense for release. 

“C’mon, say it, princess,” he drawls, voice even more nasally than usual just to piss you off. “Say it and I’ll give you what you want.” 

Snarling, you still attempt to buck him off you, only for his pianist fingers to weave into your hair and grip tightly. 

“Just fuck me already, I swear to God, Gojo, I’ll–” 

“No. You know what to say. And say it nicely .” 

Heat paints you from your chest all the way to the tips of your ears. You want it, want it so badly. When he leans down to rock his hips, you want to yell. His lengthy cock rubs up along your cunt, splitting your lips so that he can nudge your sensitive clit. Naturally, your body spasms at the touch, more arousal leaking out of you. 

You need it. 

Just like your cunt, your eyes feel damp from frustration at what Gojo is doing to you. 

He’s been annoying you all day, even more than he usually does. 

Stealing your lunch, swatting your ass, yanking your hair… annoying little shitty things that remind you of a young school bully. Giving you winks here and there and then acting like nothing happened, flirting with whatever individual was of legal age… Filcking his boogers in your general direction– god you were just so annoyed

Then he had started to touch you a bit more, in ways that weren't exactly sexual but got on your nerves somehow. 

Brushing up against you, reaching over to fix your hair, running the tips of his fingers along the backs of yours. Reaching over to fix your cuffed sleeves. 

Cute things. 

Cute things that he did with that stupid expression on his face. 

Yeah, you know the one. With the lazy smile and half-lidded eyes. The one where he lets you know he’s doing this on purpose, and definitely not out of the goodness of his heart for the sake of an Oscar trophy. 

Asshole. 

“Gojo.” 

“Say it.” 

Gojo –!” 

“C’mon, hurry up and say it, unless you want Yaga to come in here with your whole fuckin’ cunt out.” 

Your ears burn. 

“B-Big brother, please fuck me.” 

He laughs behind you, the sound grating on your nerves like exposed wires and you try to donkey-kick back at the knee in the hopes of heeling him in the shin. 

“Just straight up ‘big brother’? Not even ‘step brother’? Fuck, you’re depraved ,” he snickers. 

You open your mouth, ready to spew obscenities at the white-haired freak, only to choke on a strangled noise. Gojo’s already pushing his cock in, so unnecessarily long and just big

As his large hand keeps your head pressed down onto the desk, your manicured nails scrape against its surface. 

Sure, you’re absolutely soaked, which should definitely assist with his glide in. But he hadn’t spent a single second to properly prepare you to take him, so your cunt is perhaps just on the wrong (right) side of tight.

“Fuck–” You whine, knees buckling. “God, it’s b-big–”  

It only makes him even more feral, knowing that you’re enjoying his cruel treatment. It’s stupid. You like it when he’s mean and he knows it, which makes it all the more terrible and perfect for you.

With how he has to push into you slowly, you feel every searing inch of his invasive cock entering you. The plush ridge of his glans rubs against every spot that you know exists until the cockhead is pressed up nice and snug against your cervix. Your body twitches, saliva pooling in your cheeks because you know there’s still a few more inches of him that he hasn’t fit inside you. 

“Ooh, fuck, look at that, huh?” He groans out, smacking your ass and earning a yelp from you. “Taking your brother’s cock like your cunt was meant to be stretched wide for me, huh?” 

You heave when he starts thrusting unceremoniously, not caring if you’ve been given a proper moment to adjust. 

“Fuck, you’re tight,” he grunts. “You ever let any of those stupid boys fuck you?” 

You shake your head, playing along with whatever ungodly under negotiated kink roleplay he’s got his empty head filled with. 

“No, big brother,” you sniffle, as he fucks you in measured half-thrusts. “N-No one’s touched me before you.” 

He outright groans at that, his hips punching forward with force that has you crying out. His stupid pretty-pink tip is ramming against your cervix, making you twist uncomfortably beneath his hold against the desk. 

"Fuck, that's right. No one's ever gonna fuck you as good as your brother will, huh?"

Nii-san – big brother, I– fuck, it’s so much, please slow down!” You shriek, as he grunts, panting and laughing all at once. 

“Please! I haven’t taken cock before!” You lie. “My little pussy can’t take your big cock–” 

If you weren’t painfully turned on and literally begging for his attention and touch, you would have been scared. 

Actually, as his fingers tangle into your locks to tug your head back, you’re blessed with his upside-down face and you decide:

Holy shit, maybe I’m a little scared. 

His grin is outright feral, displaying his desire to fuck you and fuck you out in the most debauched and disgusting way possible. 

And unfortunately, that’s what has you cumming. 

You cry out, shame flooding you like a busted dam. The humiliation and pleasure courses through you as he continues to piston in and out of you. 

“Fuck, you nasty little whore,” he wheezes out, his hips stuttering at the sensation of your pussy clamping down on him. “Cumming on your big brother’s cock like this. Untouched, at that. Fuck, what’s mom gonna say about this?” 

Don’t –!” you sob, drool trickling out of the corner of your mouth. “Don’t bring my mom into this–” 

“Yeah?” He taunts. “Or else what?” 

“Fuck you–” You yelp when he smacks your ass several times, your skin red with a prominent hand-shaped mark. 

“Don’t you have any manners, lil’ sis? Or do I have to dog-fuck your brains out until you learn ‘em?” 

Right before you can spew obscenities at him, he once again robs you of your speech. This time, it’s with his arm looping around you so he can rub at your clit with his fingers. 

“G-Gojo–! Aah–!” 

You screech as he slaps your bundle of nerves, only to circle it slowly. Keening at the sensation, your thighs tremble when he lets go of your hair, your cheek mushing once more onto the desk for support. 

The sound of his cock driving in and out of your hole wet and squelching. You’re dripping, his cock shiny and glossy with how much you’re leaking around him, getting his balls fucking sticky with it. At the base of his cock, there’s a circle of your cream, and he laughs at how good you’re taking him for all your bite and bark. 

“So good,” you find yourself sobbing out, against your better judgement. “Your cock feels so good– I’m gonna, gonna cum again, nii-san !” 

He laughs, rubbing at your clit harder. 

When your orgasm drags you further into the depths of sin, your breath stutters and you choke on your spit. Gojo doesn’t let up, still fucking you with those thrusts that has your heart stammering in its cage. 

Beneath him, you twist, trying to free yourself from his ministrations. He never lets up, knows you like it rough and raw like this, taking his cock like you’re just his personal fleshlight. 

Right as you manage to pull air into your lungs, his fingers wrap around your throat, the other (previously on your pussy) slaps over your mouth. 

Your eyes bulge in their sockets as he uses your head and throat for leverage, yanking you halfway down onto him. 

“You know what’s gonna happen next, lil’ sis?” He asks, canines bared like a predator about to rip your throat out. “Wanna know what I’m gonna do next?” 

Beneath him, you tremble, tears in your eyes and snot escaping your nose from the onslaught of orgasms he had given you. You’re shaking like a leaf in his grasp, unable to move or make a sound. Even your breathing is difficult, what with his fingers clutching your throat. 

“I’m gonna dump load after load of cum into your pussy,” he laughs, slapping at your clit with his long fingers. 

“I’m gonna get you pregnant, baby. That whatcha want, huh? Get all fuckin’ big and swollen with step bro’s brat? Oh fuck, you do, don’t you, heh– Felt your cunny squeeze ‘round your nii-san ’s cock. C’mon– think I can get another one outta ya?” 

You scream weakly behind his palm as he fucks you faster, harder, his tip pressing up against all the right and wrong spots inside you. 

Stars and black spots speckle your vision as you feel your muscles tense up from how he’s handling you. His balls swing sticky and heavy against your clit, the weird sensation of dampness and friction sending shocks of electricity throughout your sensitive body. 

“Yeah, you can– yes, you fuckin’ can, baby, c’mon,” he pants, sounding like he’s been running miles as he piston-fucks your sloppy hole. “C’mon, cum around your big brother’s cock. Be a good little girl for me, c’mon. Make your nii-san proud. You can do it! Milk my cock dry, milk my fuckin’ cock dry–” 

And you’re doing exactly what he says, the last thread of your bodily sanity and self-respect snapping as you weakly convulse in his grasp. 

Heated pleasure and pain rushes through your veins like liquid poison and you swear that you black out for a moment. 

Above and behind you, Gojo snarls, slamming into you with vicious abandon until he stills with his cock kicking up spurt after spurt of boiling hot cum. 

When he lets go of your throat and mouth, you pull in oxygen, shaking and shivering. Tears are still running down your face as you gasp for air, allowing it to soothe your lungs and frayed nerves as Gojo curses. His hips still grind against your ass, earning exhausted whines from you as you feel his cum trickling out. 

“Fuck,” he groans out, rubbing his large palm up and down your side before squeezing. 

You’re exhausted, tired, fucked out. 

So you just lay your upper body on the desk. Gojo’ll take care of you. He usually does, as much of an asshole as he is– 

“Damn, my juniors are leaking out of your well-used pussy,” he comments, spreading your cheeks and cunt while squatting behind you. “What do you think mom’ll say?” 

Robbed again of your ability to coherently speak or even think, he pushes his tongue into your cunt. Lapping at your entrance, he swirls his pink appendage around your swollen clit before giving it a suck amidst your squeals. 

“Would that make me an uncle or a dad or both?” 

Dead, you think, as you try and reach around to smack him.
