general nerdsuki ݁ ˖ headcanons 𓂃
sfw hcs:
nerdsuki ݁ ˖ who refused to wear glasses back in middle school because he thought it made him look like a dork. now, he kind of doesn't care.
nerdsuki ݁ ˖ who is actually so smart, quick at pattern recognition, and undeniably intelligent. despite his natural intellect for stem, he still does study a lot! he likes going to cafes to study actually more than libraries…we all know he gets perfect grades across all courses.
nerdsuki ݁ ˖ who's been collecting pokemon cards since he was a kid and has a whole collection. back in middle-school, he would constantly tease izuku about having better cards etc..
nerdsuki ݁ ˖who’s studying mechanical engineering and genuinely enjoys it. he’s a man who loves logic, but also wants to be involved in hands-on projects in the future.
nerdsuki ݁ ˖ enjoys going to the gym, eating healthy. he also plays competitive sports as an emotional outlet for him. primarily boxing, but that necessarily isn’t his main focus at the moment especially with engineering.
nerdsuki ݁ ˖ who’s become so buff and big over the years. strong, calloused hands from working out. undeniably he will tower over you because he did get a random growth spurt.
nerdsuki ݁ ˖ who actually gets hit on a lot. within and outside his engineering cohort. he’s surprisingly not cruel about it, but again, it isn’t his focus.
nerdsuki ݁ ˖ who realises he likes you at some point, because it started with comfortability…and then noticing just the small things about you that really matter. yes. he knew you had a crush on him the whole time … but now it’s just finally liking you back woohoo
nerdsuki ݁ ˖ who doesn’t really know what to do with his feelings for you. he's not necessarily immature about it, but he's also not very outward about it. you actually have to kinda make the first few moves to get him going. like putting your hand close to his.
nerdsuki ݁ ˖ who prides himself on spoiling you. dating or not. he kinda likes the idea of making you smile, seeing how you literally bloom when he does something for you.
"katsuki...you don't have to do this, you know?" you'd say. but you've got this goofy, uncontainable smile that lights up your whole face.
katsuki's heart tightens. yeah. he knows he didn't have to, but he wanted to.
"it's fine. don't make it weird."
nerdsuki ݁ ˖ who always walks you to the door after dropping you home, making sure you get inside safe. he says it's just habit, but...we all know it's not.
nerdsuki ݁ ˖ when you're dating him loves kissing your forehead. there's something just so intimate about it, and it's not overly the top either. he enjoys the action of pushing your hair to the side to get you a peck.
nerdsuki ݁ ˖ who likes sitting in silence with you. whether it be in his room, or yours, he doesn't care. again, there's a strange comfortability of simply just being able to be in your presence. like you both could be studying for finals or something, and he's studying, focused. win-win situation.
nerdsuki ݁ ˖ who lets you rest your head in his lap while he's studying. somehow.
"get off me." he'd say, grumbling as he literally makes space for you to lay down. he doesn't move for the rest of his study session.
nerdsuki ݁ ˖ who displays his love for you in more intimate, personal ways instead of in a public approach.
nsfw hcs:
nerdsuki ݁ ˖ who loves, loves fingering you.. he likes having you conveniently over his lap, bottom pressed against his erection while he stuffs you full with his fingers. he'll go knuckle deep into your dripping cunt, curling his fingers, eyes fixed on the way your face screws up in pleasure.
nerdsuki ݁ ˖ who loves just humping you from behind, panting into your neck as desperately pulls your hips back against him.
nerdsuki ݁ ˖ who begs for just the tip, hand groping his erection as he stares at you with the softest eyes. his lips are all over you, pampering you as he ruts his cock against the skin of your thigh.
"please..." he's panting against your neck, all desperate.
"what are you doing kats," you groan, turning over to sleep. "you're always so mean to me, why should i let you?"
a drawn out defeated whine leaves his lips. "just the tip, just the tip, please...please..!" his brows furrow in frustration, precum spilling from his cock. "it's been a rough day, is all.."
"no." you close your eyes, feeding to your own exhaustion.
"okay.." he doesn't push any further. he wraps a shaky hand around his cock, whimpering as he gets off.
the sloppy sounds of katsuki jerking off brings a familiar heat between your legs. with a tired groan, you turn around. "fine. just the tip."
katsuki wastes no time before he's pushing his fat tip against your pussy, sliding it in and out.
"f-fuck..! so sensitive.."
he's shifting his hips so just his tip is inside of you. with a spare hand, he pumps the remaining length, balls tensing at the way your pussy sucks him in.
but you can tell better than anyone. he's thinking, plotting. he has this look on his face, mouth slightly agape, eyes too focused on the way your arousal coats his tip, that he wants to go deeper.
and you know it's over as soon as his thumb finds your clit, frantically rubbing circles on it.
"r-remember just the tip!"
"i'm..f-fuck!"
katsuki topples on top of you, hand holding the back of your head as he tunnels all the way in. a light, relieved whimper escapes his lips as he begins moving, balls slapping against the underside of your ass.
nerdsuki ݁ ˖ who...enjoys exploring all of you. he's been inside your mouth, and your pussy. so.. what about your ass?
nerdsuki ݁ ˖ who tears up at the feeling of you tightening around him, writhing as you struggle to take his fat cock up the ass. lowkey he thinks the idea of anal is so gross at first, but when he tries it with you, he's addicted. he also may shove two fingers down your cunt just to see how you'd react.
nerdsuki ݁ ˖ who lowkey cums very quickly. but that doesn't been he doesn't enjoy overstimulation. it's not his fault your pussy just feels too good..
nerdsuki ݁ ˖ who gets really frustrated when he can't make you squirt for the first time.
"'suki it's okay..it still felt really good!" you say, hair messy as you feel yourself drifting to sleep from exhaustion.
"no, no it's not okay." katsuki's hands are already moving down to your clitoris, rubbing meaningful circles around the bud.
his cock is already finding its way to your pussy before swinging his hips back against yours. along the way, frustration pulls at him, a sense of insecurity clouding his vision as he pistons in and out of you.
if it meant making you squirt, katsuki has no problem fucking you through the overstimulation. he's stubborn like that, broken whimpers filling the air as he feels his balls struggling to give you more. "w-wanna make you cum b-but it's too much!".
then, there it is. that feeling in your tummy. it's strange, unfamiliar. overwhelming.
"w-wait..! s-stop! katsuki!" your voice comes out panicked, frantic hands finding his toned torso. "think i'm going to-"
katsuki's brain is too fogged, glasses placed somewhere absentmindedly to care. his only focus right now is making you squirt.
burning at the sight of you! (tutor!nerdsuki & camgirl! reader) hc 𓂃
sfw hcs:
nerdsuki ݁ ˖ who, at first, paid no attention to you. it starts with routine, being around you because he’s basically getting paid to tutor you, then it grows into familiarity. he starts picking up on your habits, the way you play with your hands, pick at your skin, avoid eye contact when you’re unsure. he picks up on it all.
nerdsuki ݁ ˖ who eventually reciprocates, like not necessarily romantically, but the tutor sessions move from the library to a nearby cafe. he’ll grumble something about it being quieter (it’s actually kinda loud), and then he’ll pay for both of your drinks. first time, he actually got your order completely wrong because he thought you liked heavily caffeinated drinks, but you were too nice to mention it.
nerdsuki ݁ ˖ who notices the way your face grimaces a bit, so the next time around he tests a theory and gets you a sweeter drink (the could’ve literally just asked you personally?). always tends to pay out of generosity just because of the way he was raised. (headcanon mitsuki drilling into his head about how he should treat his girl…. wait! what? wait a second..)
nerdsuki ݁ ˖ who actually starts liking you out of his own will. and it feels like he's just suffocating with these feelings. he hates it.
nerdsuki ݁ ˖ who catches himself smiling when you get a question right and your smiling really hard, trying to contain your excitment.
"oh my god, i actually- i actually got it right!"
you flicker between katsuki and the working out on the paper.
"yeah, yeah you did."
you're staring forward with this victorious look on your face. "and! and! it was a really hard question to? how much marks would this be worth on the exam?!"
"around 15 marks."
he watches you giggle to yourself, holding up the paper, as you celebrate. "yeah...yeah so if i can get this question right, that means i'm perfectly safe for the exam!"
he's never seen you this expressive in his whole life really. you're normally quiet, contained, and careful with your words. but this must mean a lot to you, so he keeps his mouth sealed.
the sight is actually quite endearing. his chest tightens, softening around the edges as his lips curl just a bit.
but, he catches himself before you catch him. "alright, we still have five more questions to go through."
nerdsuki ݁ ˖ who starts finding meaning in meal prepping. he excuses it when he slides it over the table to you, and says he just made too much for the week, but actually because a part of his love language is acts of service and gift giving.
nerdsuki ݁ ˖ who starts considering you in mind. he starts going to the cafe you work at to study, stays till late, and acts like it's just convenient to drop you home after your close. it's kinda uncharacteristic, but he's stubborn like that.
nerdsuki ݁ ˖ who catches you itching to shit talk about your group in one of your shared courses.
"how's your group?" you ask, quietly trying to fill in the air.
"shit," he says, skimming over the shared word document made by him for his own group. "might as well do the whole thing myself."
you laugh lightheartedly, before falling silent are you stared at your own screen. "that sucks.."
"yeah, you?"
"they're okay, they're nice people."
there's something odd about your tone, something dismissive, but also there itching to be said.
"really?"
"well actually..."
and he's immediately leaning in to listen as you start berating each team member one by one.
nerdsuki ݁ ˖ who doesn't judge you for being a camgirl because he lowkey gets off to it lol.
nsfw hcs:
nerdsuki ݁ ˖ who gets comfortable enough with you. (towards the start when you guys actually get in a sexual-typa relationship). his cock is really, really pretty. but, that doesn't mean he's kinda nervous himself. but he still wants to do stuff with you, so at the start, it was just cute handjobs.
nerdsuki ݁ ˖ who likes fucking you in the same skirt you wear on your livestreams..
nerdsuki ݁ ˖ who enjoys eating you out, because it's you. and you just smell so you.
nerdsuki ݁ ˖ who i'd say isn't really an exhibitionist? again, i feel like he'd like his privacy, but also a part of him doesn't want to share you...
nerdsuki ݁ ˖ who at first, fucks you through your panties, or just along your pussy, sometimes tempting himself by pushing against your entrance, grinding and humping without any penetration yum....
nerdsuki ݁ ˖ when you two start actualy properly having sex, he lets himself slip when he's fucking you, and he just says stuff..
“could never replace you for anybody,” katsuki’s cock pressed hard up against your cervix, groaning as you squeezed him. “s-see how much my cock likes your sweet pussy?”
you nodded frantically, katsuki’s hips eratic as he dove back into you.
“‘wanna fuck a baby into that pretty tummy of yours,” he moaned out. his fingers found purchase to your stomach, dipping lower to where your uterus would be. “let everyone know i belong to.”
your tongue lolled out at the thought, desperate pants filthing the air. his hand moved to your throat, fingers wrapped around the column of your breathing pathways.
“knew that’d turn you on,” his grip tightened, eyes fixed on the red blossoming over your expression. “fuck you’re so cute— shit you’re tightening around me..”
nerdsuki ݁ ˖ who has a thing for fucking you from behind, balls slapping against your sensitive clit.. because he lowkey may feel kinda embarrassing if you do see the way he looks when he's about to cum (most delicious sight ever i may say)....
nerdsuki ݁ ˖ would totally make a tape with you but keep it for himself.
nerdsuki ݁ ˖ who thinks you have the most pretty pussy ever, and in fact may not want to do this with anyone else.
