NERD!SUKUNA HEADCANONS - Part 2
You can find Part 1 here
Modern!Sukuna x Reader (female). College AU. 3.5k words 18+, fluff + smut (sex on the kitchen table, oral (both receiving), cockwarming, cumshot). "Enemies" to friends to fuckbuddies to lovers. Reader is shy and struggles with her grades. Sukuna is a genius but bad at feelings ;) Minors don't interact. Divider @/.lacedolliee.

Nerd!Sukuna, who tries to ignore that nagging feeling in his chest anytime he looks at the empty chair across from him, where you used to sit those last few weeks during your assignment.
Nerd!Sukuna, who lies awake at night, haunted by thoughts of you and the what-ifs, cursing himself because he can solve every academic problem and get top grades in all his classes but has no idea how to deal with his feelings.
Nerd!Sukuna, who can't help but stare at you from across the room in the classes you share, feeling a heavy feeling in his chest when he sees you gnaw on your Hello Kitty pen and blink in confusion as you try to make sense of what the professor is explaining.
Nerd!Sukuna, who can feel your eyes on him, too. And he thinks it's fucking cute how you look like the deer in the headlights anytime Sukuna catches you staring. He winks at you and smirks, acting all cool, but there's this suspicious fluttery sensation in his stomach anytime you smile shyly back at him before looking away again.
Nerd!Sukuna, who is secretly into poetry, and finally finds an outlet for all those strange feelings he has been experiencing lately when, one sleepless night, his gaze lands on one of the notebooks he always has on his nightstand, and he grabs a pen and starts to write, ending up scribbling poem after poem about a cute girl with bad grades who drives him insane with her messy handwriting, but who somehow managed to bring so much light into Sukuna's life.
Nerd!Sukuna, who knows he has to finally face the fact that he misses you and wants you back in his life.
Nerd!Sukuna, who finds the perfect excuse to get you back into his kitchen and into his life when you get a lousy grade in one of your classes, and Sukuna bumps not so accidentally into you after class. "That wouldn't have happened if you let me help you with your studies. Come over this afternoon. Usual spot, usual time. Don't be late, princess. A little dummy like you clearly needs me."
Nerd!Sukuna, who says all that with a lazy drawl and his typical rude smirk on his tattooed face, acting as if he doesn't care whether you take his offer or not. But his heart is beating too fast while he turns around and seemingly casually strolls down the hallway, hoping he will find you at his door this afternoon because he really doesn't know what to do if you don't show up.
Nerd!Sukuna, who has to force himself to slow down and not run to the door and yank it open in under five seconds like a lovesick idiot when you knock on it a few hours later.
Nerd!Sukuna, who thinks he's really lucky as fuck when you stand there in front of him nervously biting your lower lip and hugging a stack of books to your chest, as you look up at him with big eyes and ask, "Were you serious about helping me? Because I really think I need you."
Nerd!Sukuna, who almost breaks out into a triumphant grin because he could get used to hearing you say you need him.
Nerd!Sukuna, who finally found his inner peace again now that you are back here in his kitchen, studying with him while sucking absentmindedly on your Hello Kitty pen and getting so cutely embarrassed when asking him questions that you think are stupid.
Nerd!Sukuna, who surprises himself with how patient and gentle he is with you, explaining the same topic over and over again until you finally understand it.
Nerd!Sukuna, who loves to teach you about topics he is passionate about, going into an hour-long rant about the smallest details, complete with big hand gestures and an excited sparkle in his maroon eyes behind his big glasses. And to Sukuna's delight, you don't interrupt him or think it's boring, but instead rest your chin on your hand and watch him the whole time with a dreamy little smile on your face, as if you think he hung the moon.
Nerd!Sukuna, who tells you you will need extra meetings to prepare you for your upcoming exams, even though he can tell he already taught you really well, but he likes the thought of spending more time with his cute little study partner.
Nerd!Sukuna, who joins you on your side of the kitchen table to explain maths to you until late in the night, until your head suddenly lands on his shoulder, and Sukuna hears your soft snores, making him gulp hard even as he murmurs hoarsely, "Did you really fall asleep on me, brat? In the middle of my explanation?", automatically acting annoyed even though he actually likes how warm you feel against him and how sweet and enticing your flowery perfume smells when you are so close to him.
Nerd!Sukuna, who doesn't get an answer because you really are fast asleep on his broad shoulder, and all Sukuna can do is admire your sleeping face, for once not having to pretend he doesn't care and averting his gaze again after a moment, but taking his time to take in your features, which he thinks are really fucking pretty to him.
Nerd!Sukuna, who, instead of shaking you awake, carefully lifts you up in his strong arms and carries you to his bed, carefully laying you down and tucking you into his blanket. He has to bite his lip hard because fuck, seeing you in his bed does things to him. To his dick and to his heart.
Nerd!Sukuna, who sleeps on the couch that night, which means he gets about an hour of sleep, and the rest of the night, he is lying awake, almost losing his mind because he knows you are in the next room, in his bed, so cute and sexy and his mind is showing him all the nasty things he would like to do with you. Like having you under him with your legs wrapped tightly around his hips, sobbing his name and leaving scratches on his back while begging him to nut in you.
Nerd!Sukuna, who can't stop thinking about you in his bed after that one night, and only manages to restrain himself from really trying to hit on you by telling himself he wants you to be able to focus completely on your upcoming exam and not get distracted by how good Sukuna's dick is.
Nerd!Sukuna, who spends a whole Sunday preparing index cards for you with all the important topics you have to remember, all written carefully in his elegant handwriting, making him feel like he is handing you a love letter when he gives you the cards on Monday morning.
Nerd!Sukuna, who feels so strangely warm when you run up to him after your exam with a big smile and an excited "Oh my God, Kuna! I passed!" and before he knows what's happening, you jump into his arms, laughing loudly as you hug him tightly, and somehow there's a smile on Sukuna's face and a buzzing in his veins that feels damn nice.
Nerd!Sukuna, who can't get the way your smaller body felt pressed against his out of his mind again, but doesn't know how to get you to hug him again, so he just keeps teasing you to at least get you to playfully hit his biceps or push him away by placing your hands on his chest.
Nerd!Sukuna, who grins when you tease him back and lightheartedly make fun of how big of a nerd he is with his color-coded notes and know-it-all attitude and smartass remarks all the time.
Nerd!Sukuna, who tells you you are just jealous because you don't have such a big array of sticky notes and pens like he has, but he will be charitable and donate some to the ones lacking proper academic attire, aka you.
Nerd!Sukuna, who, for some unfathomable reason, really likes it when he sees you using his sticky notes in class. Maybe because it makes him feel as if you are his.
Nerd!Sukuna, who gets ridiculously pissed off when another guy tries to offer his notes to you. But the problem is solved fast when Sukuna strolls over and puts himself between you and that loser, towering menacingly over him and plucking his stupid notes out of his hands and tearing them into tiny little pieces right in front of him, "She already has me to study with. As if she could learn something useful from you anyway. Get lost before I do the same to you as I did to your sorry-ass notes!"
Nerd!Sukuna, who tries to downplay it when you ask him why he acted that way, not ready to admit how much you mean to him and how possessive he is of you.
Nerd!Sukuna, who catches himself grabbing a sticker book for elementary teachers on his next shopping trip to the stationary store and starts gluing motivational stickers on your notes with playful comments from him.
Nerd!Sukuna, who discovers he really enjoys hearing your laugh, especially when you reach out and put your smaller hand on top of his much larger one, your soft fingers shyly playing with his while you smile and giggle about a rude but very fitting remark Sukuna made about one of your professors. And suddenly, Sukuna can't hold back anymore. You look so cute that it makes him drop all his rational thoughts and just act on his desires.
Nerd!Sukuna, who kisses you for the first time right then and there, leaning over the kitchen table to grab your chin with his hand and press his lips against yours.
Nerd!Sukuna, who feels almost high from how eagerly you open your mouth for him and let him lick into your sweet, hot mouth. The noises you make get him feeling dizzy with adrenaline, like he usually only feels when he walks into a challenging exam. A cute, breathless "Sukuna..." sighed against his lips, and Sukuna's dick is so hard he thinks he will go insane.
Nerd!Sukuna, whose big, nerdy glasses get all fogged up from how steamy your kisses become. Deep and hungry and sensual, as if both of you have been craving this for weeks and don't know how to stop now that you finally gave in to your desires.
Nerd!Sukuna, who also fucks you for the first time right there on the kitchen table, on top of all your notes and books, not wasting any time because he can't go one more second without being balls-deep inside you.
Nerd!Sukuna, who doesn't care about ruining his notes because it's more important to fuck more of those cute mewls out of you that you bless him with any time he rolls his hips into yours and his cock caresses that spot deep inside you that makes your pussy clench so sweetly around him as if you never want to let go of him again.
Nerd!Sukuna, who thinks this is absolute perfection, fucking you on his kitchen table with his and your study notes and books scattered all around you while you look up at him with that cute expression on your pretty face. And your little skirt that always drives him crazy, is flipped up to let Sukuna watch his cock slide in and out of your pretty pussy, so wet from your juices that it's dripping down onto your history book.
Nerd!Sukuna, who tries to hold back but can't when you cum on his cock with such sweet moans and loud squeals, making Sukuna barely manage to pull out before he nuts hard all over your swollen pussylips and puffy clit and the notes underneath you.
Nerd!Sukuna, who can't bring himself to care about the messed up notes and instead leans down to bury his tattooed face between your spread legs and licks his cum off your pussy, until you scream his name and tug on his hair and bless him with another one of your fucking cute orgasms.
Nerd!Sukuna, who asks you afterward if you want to stay the whole night and feels uncharacteristically nervous about it because sex is easy, but actually sleeping in the same bed with someone is a new thing to Sukuna.
Nerd!Sukuna, who, for the first time since he started college, doesn't go through his notes or read a chapter in one of his academic books before falling asleep but instead fucks you with slow, deep strokes on his bed and then holds you and kisses you until you both fall asleep snuggled tightly against each other.
Nerd!Sukuna, who can't stop laughing when he walks into the kitchen the next morning and finds one of the motivational stickers he bought glued to his coffee mug, with a scribbled note in your messy handwriting: "Peak performance last night, not just at academics but also on the kitchen table and in the bedroom. A+ Keep it up!"
Nerd!Sukuna, who spends the next week not just studying with you but also fucking you thoroughly every chance he gets. He's analyzing every moan, every reaction of your body, learning what you like and committing it to his memory, striving to be the best fuck you ever had because he's ambitious, even when it comes to sex. (Or maybe he is trying to make sure you will never go to someone else to satisfy your needs.)
Nerd!Sukuna, who is super intelligent and always at the top of every class, but knows nothing about love or relationships. But what he knows is that he wants to have you around him as often as possible. And he really really likes spending time with you, studying together and kissing and fucking, and sometimes just talking for hours while holding hands atop your notes.
Nerd!Sukuna, who suspects you kind of like him because you crawl under his kitchen table one evening and give him such a thorough and loving blow job when he complains about being stressed as fuck. You let him cum all over your pretty face while suckling sweetly on his throbbing tip, and Sukuna kind of thinks he can actually see little hearts in your eyes when you look up at him.
Nerd!Sukuna, who loves it when you sit on his lap and keep his cock warm until he is finished with his studies. It gives him even more motivation to hone his reading speed because he only allows himself to move when all his work is done before he grabs your hips and fucks his cock almost desperately into you, fucking you silly, with his glasses hanging askew on his nose from how wild you drive him until you both explode at the same time with loud unrestrained moans.
Nerd!Sukuna, who catches himself wishing your warm naked body was wrapped in his arms on the nights you don't sleep over at his place. And it's certainly not helping that he can smell your flowery perfume on his pillow, and it makes him downright yearn for you.
Nerd!Sukuna, who knows it's not just sex, but who doesn't know how to deal with all those newly discovered feelings, so he just keeps helping you study and gives you orgasms, and cooks for you and buys you all those pretty study supplies in your favorite color and with Hello Kitty stickers which you love so much. He hopes you know this is his love language.
Nerd!Sukuna, who outright refuses when his professor wants to give him a new partner for the next assignment. Sukuna's glare is poisonous when he uses his "my success reflects really well on your university, so you better not make me leave and sign up somewhere else" card to get paired up with his girl again.
Nerd!Sukuna, who thinks this was a pretty good thing to do, judging by the way you cling to him that afternoon and shower him with kisses and smiles, and ride him slowly with your cute little skirt on, mewling his name into his ear and telling him how good he feels inside you.
Nerd!Sukuna, who sits at his kitchen table with his chin resting on the back of his hand, watching you thoughtfully while you suck on your Hello Kitty pen and try to answer your history exercise, looking so cute that it's almost unbearable.
Nerd!Sukuna, who wants to tell you he never felt this way about anybody and never even thought he was capable of feeling this way. But this is a thousand times harder than any academic problem Sukuna ever encountered, and so he says nothing, and when you catch him staring and are about to open your mouth, he jerks his head sternly and drawls, "Eyes on your notes! I don't want to hear a single word until you have completed that question!"
Nerd!Sukuna, who knows you have become his weakness, when he can't stay strict with you and ends up shoving his notes across the table, offering to let you copy them. "But promise me you will read the whole thing, so you learn something at least."
Nerd!Sukuna, who regularly cooks dinner when you are over at his place, making sure to only use ingredients you like. Hell, he even puts your rice into a Hello Kitty shape because the way your face lights up with joy when he does that makes his heart feel so full it's almost bursting.
Nerd!Sukuna, who's standing at the stove making dinner, only wearing his grey sweatpants and no shirt, because he likes the way your eyes always stray to his muscles and tattoos. He smirks playfully over his broad shoulder when you comment on his half-naked state. "I'm only doing this for you, princess! Because I want to help you learn how to work in a distracting environment. And nothing is as distracting as my body."
Nerd!Sukuna, who laughs when you abandon your notes and walk up behind him with your Hello Kitty pen and start writing on him, using his broad back as a makeshift whiteboard. He can feel you are writing equations but still asks teasingly, "What is that, princess? Are you leaving little love notes on my back?"
Nerd!Sukuna, who, for the first time in his life, feels something akin to flustered when you giggle and suddenly stop writing equations and instead really start drawing little hearts on his back and placing soft kisses on his skin right next to your drawings and murmur against his skin, "Hmm maybe? Would you mind me writing love notes on you?"
Nerd!Sukuna, who thinks you must feel how fast his heart is beating, when he answers, "I wouldn't mind at all."
Nerd!Sukuna, who feels a big smile spread over his face when he feels you write "I really like you, Kuna."
Nerd!Sukuna, who drops the cooking spoon and turns around and wraps his arms around you, pulling you against his naked chest while saying, "I fucking like you too, princess."
Nerd!Sukuna, who finally knows what to do because there is no way you are beating him at being the first to confess. "You know, you should really catch up and be my girl because I've already been your boy for weeks, and this equation only works if you are mine, too."
Nerd!Sukuna, who can't believe how lucky he is when you hug him tightly and tilt your head to smile at him with happy tears in your eyes, telling him that, of course, you are his girl. And you get on your tiptoes and grab Sukuna's tattooed face with both hands, showering his cheeks and nose and lips with kisses until even Sukuna's glasses are smeared with your lipstick, and both of you are laughing breathlessly.
Nerd!Sukuna, who rolls his eyes playfully when you tease him later that evening, "Sooo, this whole talking about your feelings is pretty hard for you, huh? Looks like I finally found something my favorite super nerd doesn't excel in."
Nerd!Sukuna, who won't stand for that (even though you are right) and ends up getting his poetry notebook out of his nightstand and handing it to you with a grin that is a bit less confident and a bit more nervous than usual, "Here, for you, princess. I have to inform you that while I may not be that great at talking about my feelings, I am pretty good at writing about them."
Nerd!Sukuna, who has never felt as nervous in any exam as he feels now while watching you read the poems he wrote about you.
Nerd!Sukuna, who is glad he is so tall and strong, or you would tackle him to the floor with how you throw yourself into his arms and cling to him like a koala with tears streaming down your face and crying about how sweet Sukuna is.
Nerd!Sukuna, who has never been called sweet before but who feels like he could get used to this when it comes from you.
Nerd!Sukuna, who spends the rest of the day in bed with you, getting the best sex of his life and hours of kisses and cuddles, because apparently, yes, he really is very good at expressing his love for you in poetry form.
Nerd!Sukuna, who sits beside you now in every class the two of you share and who starts using your Hello Kitty sticky notes and sends death glares at anyone who dares give him a side-eye for it, asking them snidely, "What? Do you have a problem with Hello Kitty? Or with my girlfriend?", and then laughing softly when you elbow him and tell him to stop scaring people.
Nerd!Sukuna, who knows he has found his perfect study partner. The only one he ever wants.
Nerd!Sukuna, who never had a girlfriend before and never thought he could find someone who interests him as much as his studies do. But now that he has you, Sukuna found his favorite topic to study for the rest of his life.
