✰ .ᐟ your pro-athlete boyfriend NAGI SEISHIRO . . .
finds out about your Twitter stan account, 'nagi-sei’s-universe,' when you ask him to grind Stardew Valley on your PC and your Twitter account is open on your browser.
Curious about all of the content you’ve posted after noticing that you've retweeted a 'suggestive' video with a caption about him, and naturally decides to snoop.
Loves reading through all your thirsty, downright filthy tweets and retweets, and is especially interested in the videos you repost.
(It helps him figure out what you're into.)
Memorizes your username and tag so he can revisit your account.
For some reason, it turns him on knowing that you support his pro-soccer career on your account as well.
Definitely boosts his ego, and he thinks your horniness over him is so damn cute.
Plans on visiting your account when he needs to get off.
“Sei, can you come grind my Stardew Valley farm for me?”
You call into the living room, where Nagi had just woken up from a nap. “Su-uuure,” he yawns, rubbing his eyes as he drags himself into your shared bedroom where your computer is set up.“But why? You goin’ somewhere?” he questions, gray eyes following you as you grab your keys and wallet. “Mhm, just to the store to buy a couple things,” you reply, hurrying over to press a quick peck on his lips. “I just need to reorganize my barns and coops, and maybe get more animals. Try to finish it all for me, ‘kay?” you smile cheekily at him. “I’ll be back in a bit!”
Nagi watches you slip out the door before settling into your chair, clicking around your farm for a bit. She said buy more animals…when is Marnie’s ranch open? He thinks to himself with a frown, opening your web browser to search it up.
But before he can, Nagi notices your Twitter page open, with a- porn video retweeted? He raises his eyebrows, checking to make sure if it really is your account, and it most definitely is. More shocking than the video itself, though, was the caption you posted under it—‘need this w nagi seishiro right nowwww!!’ with a handful of horny emojis streaming after it.
“Hm…what else has ‘nagi-sei’s-universe’ posted?” he muses to himself, scrolling through your Twitter account with curiosity. He scrolls past a handful of more ‘suggestive’ videos, tweets about his newest games and stats, and thirsts that you’ve reposted. A video you reposted catches his eye, however—one with a girl on her knees, some guy slapping his dick against her face while degrading her: “Fucking slut. Just look at you, so whiny and desperate for my cock. Shit, you’re such a cute lil’ whore.”
Nagi almost feels betrayed that you didn’t tell him you were into this earlier. He could’ve been degrading you and slapping his cock against your face this whole time? Shit. That’s hot, he thinks, closing his eyes for a moment, and feels his pants tighten. He replays the video, imagining you in that girl’s place, and imagining himself smacking his dick on your cute face so sweetly.
Right on cue, he hears the front door open as you step inside. He considers closing the tab with your account on it, but opts to pause the video instead. Cock throbbing in his pants, Nagi’s eyes are glued to you the second you walk into the room.
“The traffic was terrible today, maybe I should’ve just gone tomo- wait…Sei, what is that?” you stare at the screen, heat blooming on your cheeks. “Hm? This? You don’t recognize it?” he asks, tilting his head. “I- why would I- ” you stutter. “Because you reposted it, angel,” he murmurs, eyes looking you up and down. “And I think I deserve something in return for you hiding this from me, yeah?”
You swallow, face now crimson. “Sei- I- ” you scramble for words, but Nagi cuts you off.
“Get on the floor and spread your legs.”
The sharpness of his tone shocks you into submission, and something in your lower belly throbs with anticipation. You stagger to the ground, opening your legs with a blush. “Now, touch yourself for me.” he says, voice husky, and you don’t miss how the prominent outline of his cock throbs. “S-Sei,” you mumble, turning your head to avoid his electric gaze. His eyes narrow. “Hm. If I do this- ” he clicks play on the video, still frozen on the screen. “-would you touch yourself properly?”
You gape at him before your eyes fall onto the monitor. Hole pulsing and twitching as the video plays, the girl’s moans and guy’s dirty talk seeping into your ears, you can’t help but slide your pants off, biting your lip to stifle your moans as you circle a finger on your aching clit.
“C’mon, angel, do more than that,” Nagi orders, now fully undressed, and you feel a bead of arousal slip out of you at the sight of his muscular, athletic body in front of you. “Nngh- Sei,” you moan out as you dip a finger into your needy, drooling cunt. It was unlike him to take such a commanding role, you think, as he palms his cock through his sweats, eyes trained on your pussy. It’s so fucking hot. “Another finger.” he commands, and you whimper. “Sei- I- I’m about to- ugh!” you whine, bucking your hips into your hand as you slide another finger inside. “S-so close!” But with a click on the keyboard, he pauses the video and says, “Don’t cum. Save it.”
“B-but, Sei! You- ugh!” you cry, fingers still thrusting weakly in and out of your sopping hole. His cock is fully erect now, standing so straight and tall and thick with his hand wrapped around it, dragging over his dick slowly. “I said, stop.” he hisses, and you freeze. You’ve never heard Nagi’s voice so cold, and for some reason, it’s so, so hot.
“Get on your knees and open up,” he breathes, the tip of his cock burning red as it twitches. Crawling over to him, you settle on your knees, opening your mouth up from below him. Exhaling sharply, he smacks the fat head of his cock against your cheek, smearing precum over your face.
“Fuckin’ slut,” he murmurs, smirk slowly widening on his features. “Just look at you, so whiny and desperate for my cock. Shit, you’re such a cute lil’ whore.” And your pussy throbs harder when you realize he’s parroting the guy from the video. You fucked yourself on your fingers to that video more times than you can count, and now, Nagi’s recreating it with you? Fuck, you could’ve just cum on the spot listening to him.
“You’re enjoying this too much, aren’t you?” he bites his lip. “Nasty girl, getting off to my fat cock slapping against your pretty face.” You moan in response, grinding your clit on your heel as he slaps his length against your face again. “Fucking hell, you’re so pretty like this,” He gasps, eagerly stroking his throbbing cock when he slaps your cheek again. “Just lookin’ at you like this- ah- fuck!” Nagi groans, thighs tightening when his hot seed spurts out, painting white ropes over your face.
Catching some of his release in your mouth, you make sure he sees it coating your tongue before you swallow it, licking at your lips with a small smirk. His chest is heaving, gentle sheen of sweat making him look ethereal in the dim light, and he swallows roughly before bringing an elegant hand to your face. With two fingers, Nagi scoops up the remaining seed on your face before sliding his cum-coated fingers into your mouth. “Good girl,” he murmurs as you choke on his fingers. “You want more of my cum, don’t you? Filthy little thing.” He remarks, and tears prick at your eyes when you nod keenly.
You’re on the edge of cumming again when he pulls away from your face. “Stand up, pretty,” he says, releasing his cock, hard again, letting it bounce against his chiseled abs. “Now, ride me like the good lil’ slut you are.”
You moan at the words as you perch yourself above him, hovering over his cock as your cunt drips slick onto his thighs. Rubbing your swollen clit on his fat tip, you whine at the sparks of pleasure bursting through you. Nagi grunts at the sensation. “Nngh- stop teasing,” he clenches his teeth, big, veiny hands wrapping around your hips before slamming you down on his cock.
With a scream, you feel the head of his cock press into your sensitive spot so perfectly. “Ah!- Sei, I- ohhh, fuu-fuck!” you wail, creaming on his dick right then and there, squirting slick down his balls and muscular thighs. He gasps at the sensation, face contorting in pleasure as he feels your weeping hole pulse and flutter around him. “You- ah, you fuckin’ slut,” he moans, sweat beading at his forehead. “Look at you- ugh- takin’ my dick so well.”
When he starts lifting you and slamming you on his cock, your jaw is already wide open, tears spilling out of your eyes as Nagi desperately chases his second release. “Ah-ahhh, fuck, your cute lil’ hole is so tight-n-wet f’me,” he bucks into you harder, grabbing one of your tits and suckling at your stiffened nipple desperately.
“Mmh, Sei! Oh-unggh-”yousob, vision hazy and mind dizzy with lust. “C’mon, pretty, cum again f’me,” Nagi groans, thrusting his cock in and out of you at a pace that makes stars flicker in your vision. The stretch of his girth is so delicious and renders your brain useless. You can barely form a coherent thought when your orgasm crashes into you, knocking the breath from your lips as you scream out his name in pleasure. “Ahh- angh- S-Sei! Ohhh, fu-fucking- ngh, Sei!!~”
You’re abused hole is aching so lewdly as Nagi bottoms out inside you with one final thrust before pulling out, cum spurting from his throbbing tip and spraying across your stomach. “Nngh- a-ah! Shiiit- so- so fuckin’ good!” Nagi whines, hands squeezing at the fat of your ass tightly.
Panting and covered in cum, you both catch your breaths as your orgasms ebb away. “Mmpf, Sei,” you gasp, nuzzling into his chest. “That was amazing.”
Nagi presses his cheek onto the top of your head with a sigh. “Mm, it was…but I’m so tired now,” he pouts, and you can’t help but giggle. “Did you even make any progress on my farm?” You inquired, looking up at him. Nagi turns away, fluffy white hair obscuring his eyes from your line of sight. “Maybe, maybe not,” he mumbles, and you snicker. “I’ll work on it for you later, pretty. Let’s just sleep now.” Nagi murmurs, scooping you into his lean arms and tumbling onto the nearby bed with you.
“Sei-! We’re both covered in- ”
“Yeah I know, I know, we’ll just wash the sheets later.”
“fuck baby, just like that.” denki groans, leaning back on the couch as you bounce up and down on his cock.
“denki i just- mmf! denki ‘m so full.”
bang! the front door slams open and snap your neck, continuing to ride denki as his roommates walk in.
“shit.” kirishima covers his eyes, clicking the door shut behind him.
“damn.” sero tilts his head, watching the way your ass jiggles after each sticky smack.
“dude!” kirishima slaps a hand over sero’s eyes.
“sorry.” denki calls out. “left half the blunt in the ashtray.” his hands grab your ass, scooting lower and starts fucking up into you. “fuck baby.” spank!
“we’ll-”
“nghhh!” you toss your head back. “fuck denki, i’m gonna- ahhh!” you gasp, spine straightening as your orgasm washes through you.
“move your fuckin hand.” sero slaps kirishima’s hand away.
“light it and pass it.” denki looks over your shoulder.
“wha- now?” kirishima drops his other arm, trying to look anywhere but at you.
sero is already walking towards the ashtray and taking a seat next to the both of you. “what? denki’s room too dirty for you, sweetheart?” blunt between his lips as he lights it.
“nah, she couldn’t wait.” denki bucks up into you, reaching over as sero passes the blunt.
“shouldn’t you.. like cover up, man.” kirishima winces when you turn to him with a pout.
“don’t like lookin at me, kiri?” you reach for him and his cheeks flush.
“think he likes lookin at you too much.” denki chuckles. “go over there.” he lifts you off his dick and plops you down on kiri’s lap.
“dude!? i- ??” he holds his hands up and squeezes his eyes shut.
“wanna fuck her?” denki lulls his head to the side and you roll your hips.
“can i fuck kiri?” you whine at denki. “please?” you push your lower lip out.
“and what about me?” sero pouts his lips out.
“what do you think baby?” denki offers you a lazy smile. “wanna give my friends a ride?” he passes you the blunt.
“mhm mhm.” you nod quickly, taking a hit and pushing it back into denki’s hand.
you lean forward, pressing your lips to kiri’s and blowing the smoke in his mouth. sero and denki watch at the way kiri flushes under your touch as you shove your hands under his shorts. you whine when his cock pops out, already glistening with little beads of pre.
“‘s big.” you lean back and pump him once before lifting up on your knees.
“bet he’ll cum in 2 minutes.” sero chuckles, watching the way you slide kiri up and down your folds.
“nahh, i give him 5.” denki pushes sero’s chest.
“guys..” he groans as you sink onto his tip. “shut up.” his hands grip your waist as he looks up at you. “pretty. so pretty baby.” he nods as you take inch after inch.
“you’re a pretty baby too.” sero purrs in denkis ear, plucking the blunt out of his hand and dabbing it out in the ashtray.
“wha- hah! fuck sero.” sero’s hand wraps around denki’s cock
“forgot how squirmy you get.” sero thumbs at his underside. “she’s got you fuckin soaked.” he hums, pumping him faster.
you can’t decide if you want to look down at kiri as you suck him in or over at the way sero has denki’s hips jerking off the couch. kiri grinds his hips up and your attention falls to him, eyes fluttering as he repeats the movement. his hands grip your waist as he starts to fuck up into you, not letting you do any of the work.
“shit hanta.” denki can’t help the way he fucks up into sero’s hand.
“gonna cum before ei?” sero chuckles.
“shut up.” denki’s thighs shake.
“nghh!” you’re clinging onto kiri as he pounds up into you.
kirishima has you held tightly to his chest as he snaps his hips up onto yours. your pussy is strangling his cock, your lips brushing against his neck as you whimper right into his ear. his fingers harden into your skin and your walls flutter, thighs shaking, with one more harsh snap of his hips, you cum with a cry of his name.
“shitshitshit.” kiri holds you down on his thighs as he fills you.
you turn your head to the side and find denki sated, breathing heavy with cum all over his abs and sero slowly jerking himself. sero gives you a lazy smile and reaches out a hand to you and you lift off of kiri. sero helps you over to him and slides you right down onto his cock.
“got you all to myself.” he brushes your hair back.
“hanta.” your lashes flutter.
“hm?” he slowly starts to fuck you up and down.
“‘m so tired.” you rest your head on his shoulder. “just.. use me. please.”
“ohhh, i know baby.” he coos, trailing a hand up your spine.
sero scoots down until you’re laying on his chest and he can fuck up into you. each drag out and push back in has your toes curling, little puffs of air leaving your lips and splaying across his warm skin. you press kisses all over his neck, trembling in his arms, breath catching as an orgasm already bursts through you.
“s’okay. i got you.” he rubs your back when he feels the tears on his neck.
“feels s’good.” you’re practically limp in his arms.
you peek out of his neck and see denki staring at you with lidded eyes as he strokes himself. you blink past him and kiri is doing the same, lips parted and letting out little moans. sero bucks up into you and you bury yourself back into his neck.
“focus on me.”
your hands tangle in his hair, gummy walls spasming around him at his low words. he hits that one spot and you gasp, yanking on his hair and he grins. he pushes against it over and over until you’re cumming and whining as he starts to fill you.
“can’t move.” you’re limp against him.
“don’t gotta.” denki rubs your back.
“gonna clean you up real nice.” he hums.
instead of taking you to the bath, they take you to denkis room and lay you back on the bed. each taking turns sucking the cum out of you.
bang! the front door opens and snaps shut.
“denki!!! why does the apartment smell like sex?” you hear katsuki walking down the hall. “you idiots didn’t invite me?”
“kats.” you squirm.
“they make you cum?”
“mhm.” a nod of your head.
“they clean you up yet?” he looks at the way they have your legs spread wide.
“mm-mm.” you shake your head.
“wanna take a bath?” he grins when you nod your head.
mean!nerd!izuku & bully!katsuki using you as their stress relief
The silence in the room was broken by uneven breathing and the slick sounds between bodies. You were overstimulated, your skin was flushed and sensitive everywhere hands had already touched you.
“Go easy, Kats,” Izuku’s voice cut through.
His tone was demanding, almost impatient, but still soft and calming.
“She has to take me too you know,” he added with an amused chuckle, green eyes carefully watching the obscene act in front of him, studying every small reaction on your face, mentally taking pictures of every mark left on your body.
And what a view he had! You— naked and bruised all over— hair sticking to your forehead as your knees were barely moving— were settled above Katsuki’s also sweaty, naked body. His large hands were harshly gripping at the fat of your ass, fingers digging in deep, shoving you down on his dick with the same energy he had three rounds ago, while you were a total mess.
The blond under you let out a long groan as he moved you with far too much ease, like you weighed nothing at all. Like your body belonged exactly where he put it. Each movement stole the air from your lungs, a broken sound slipping past your lips every single time he forced you down his dick.
Even in this state, the feeling of him twitching inside your walls was unmistakable. You had come to learn that feeling faster than you wanted to admit. The small pulse, the way his grip tightened, the shift in his breathing. He was close. Very close.
You had already come before him. Your body had gone numb for a few moments, vision blurry, ears ringing softly— but he didn’t let go. He kept you in his lap, making sure you took whatever he gave you. He kept you there until you memorized everything about him.
He shoved his dick in your sopping whole one more time before he let out another long groan, this one deeper, rougher. Soon after, you felt the hot loads of his cum hit your walls, filling you slowly, making you shudder and squeeze him without meaning to.
Your hands found his shoulders in order to keep your balance, nails pressing into his skin, breath ragged as you closed your eyes for a few moments, the dizziness overwhelming you.
“God, she’s squeezing me so hard right now,” Katsuki laughed, breath still uneven as he slightly readjusted himself under you. “You’re so fuckin’ greedy.”
“Ah, only if she was like this when it came to a high grade,” Izuku mused, green eyes moving between you and Katsuki. His large scarred hand hovered over his visible hard-on, slowly palming himself as if he was thinking. Analyzing.
Ever since this… special session started, all he did was watch you and Katsuki fuck.
Or better said, watching his friend— and your childhood bully— put you in the most embarrassing positions possible. Like he had a list prepared in his mind, crossing things out one by one.
And he started off strong.
He made you suck his dick on all fours while your bare pussy and ass were facing Izuku, because he said he wanted to study them. Said it like it was academic. Like it was part of the project.
Then, still on all fours, he started pounding into you from behind while you made eye contact with Izuku. And every time you looked away— even for a second— Katsuki stopped his movements completely and edged you for what felt like hours.
And Izuku? He didn’t help at all.
On the contrary, he lied that you looked away a few times, even when you hadn’t. Just to see how tears of frustration formed in your eyes when Katsuki stopped right when you were about to finish.
Because of course Katsuki believed his friend.
Fucking freaks. Both of them.
But what worried you the most?
You liked all of it.
At no point did you feel the need to stop and walk away. Not once. Instead, you got even greedier. And you didn’t even have a chance to fuck Izuku yet.
“I don’t even understand why we got paired with her. All she’s good for is taking dick.”
The blond’s words stung, sharp and blunt, making your throat tighten as heat rushed to your face. You hated how much they affected you. Hated that part of you felt small under them.
“Don’t be mean, that’s a quality too, isn’t it?” Izuku murmured, brushing his thumb over your flushed cheek.
The contrast between his gentle touch and the degrading words made your breath hitch painfully.
“Plus, she’s taking it so well…”
“Like a champ,” Katsuki smirked as he finally pulled out of your pussy, making you let out a deep sigh you didn’t realize you were holding.
You moved back a bit, helped by Izuku, because your body was pretty numb and your legs felt unreliable. You licked your lips when you looked back at Katsuki.
He looked so fucking good.
His blond hair was a total mess, sticking in every direction. His chest and abs were glistening with sweat, your scratches still visible across his skin. His flushed dick was sitting prettily between his thighs, all covered in your juices and his cum, slowly softening but still thick and heavy.
“You gotta help us somehow. We can’t have you be completely useless,” Izuku reminded you, his free hand coming down to stroke your bruised hip.
You hissed at the contact immediately, pain spreading beneath his fingers, the tenderness reminding you just how much you had already taken tonight.
“Doing… my best,” you managed, nodding again, sniffling slightly as your voice wobbled.
“If I had known how good that pussy feels, I woulda fucked you sooner,” Katsuki took in a deep breath, raking his eyes over your exposed body slowly, shamelessly.
“…But idiots like you turn me off,” he added with a laugh.
Your chest tightened at his harsh— but painfully true— words.
Unfortunately, you had never been the smartest in your class, nor the brilliant one. You were average. You had good grades. No failing courses. No complaints from professors that you need a tutor. But when you got paired up to do a project with two of the smartest guys at UA University, they reminded you how stupid you actually were.
You weren’t of any help to them, as Katsuki put it. Your research was badly done. Your citations were all wrong. Your materials were not reliable. And your writing skills were “lacking something,” in Izuku’s words.
So how else could you be of help to them other than letting them use you as… their stress relief? And all of you had something to win from this. They get some quick action— no questions asked, and you get… your part done. And some good dick, but that’s beside the point.
“Kats, don’t be an asshole,” Izuku frowned at his friend, though there was no real heat in it. Both hands moved to cup your ass, pulling you closer to his lap with clear intention. “Ignore him, okay?”
“Ah— okay,” you nodded weakly, wrapping your hands around his shoulders, your head falling into the crook of his neck.
“Can you keep going?” he asked softly, voice right by your ear.
“Yes,” you replied sleepily, your body melting, feeling strangely comfortable in his arms.
Izuku smiled against your skin.
“You’re such a hard-working girl,” he chuckled quietly. “…when it comes to being a little slut for us.”
Katsuki laughed loudly at his friend’s words, smirk never leaving his face as he guessed you were probably hoping for Izuku to be nicer. Softer. Better.
“I’m— I’m sorry,” you muttered, hiding your face against Izuku’s shoulder.
“No, no— no worries, baby. We like you more this way,” Izuku admitted with a gentle tone, almost sweet.
You moved away from his neck and looked back at him, noticing how he was smiling at you warmly— yet his eyes had that teasing glint in them.
“You… do?”
“‘Course idiot, who wouldn’t like a girl who’d do anythin’ for some dick?” Katsuki laughed as he shook his head in disbelief. “God, stop bein’ so stupid. No wonder I bullied you when we were kids.”
Your face grew red at his words, heart beating faster. You opened your mouth, ready to defend yourself, but only a moan escaped your lips when Izuku’s fingers moved between your legs, reaching your sticky folds.
Two of his fingers spread you open slowly, showing some of Katsuki’s cum leaking out of you. It dripped down on his bulge, messy and thick.
Izuku smiled at the sight.
“I’m sure we can fit more in here,” he muttered more to himself than to you.
“I like to take you when you are already full… test how much more you can take.” His voice dropped lower, his hand squeezing your bruised hip again.
“Get these off for me, yeah?” Izuku smiled, his eyes flicking towards his pants that were clearly straining him.
You nodded quickly and moved your trembling hands down, fingers starting to unbuckle his belt. The metal clinked softly in the quiet room. You heard him hiss when you accidentally brushed against his bulge through the fabric. It was massive. Almost painful to look at.
You pulled his belt out of the loops and moved to unbutton his pants, fingers clumsy but eager. He raised his hips slightly to help you drag them off his hips.
You turned your attention back to his crotch, gulping when you saw his boxers.
There was already a wet patch on them.
A big one.
He had been enduring that all this time. Sitting there, watching, pretending to be calm while he was that hard...
What a freak, you thought.
“These too, silly,” Izuku lets out a breathy chuckle.
You nod quietly as you bring your hands to the waistband of his boxers, dragging them slowly down his hips. His hardened member springs up, almost hitting your stomach.
His tip is pink and leaking with pre-cum. His length is close to Katsuki’s, maybe even bigger.
“Gonna take me, yeah? Nice and slow,” Izuku whispers in your ear, lips brushing your skin, making you shudder. “Not like Katsuki,” he assured you, eyes flicking towards his friend.
The blond rolled his eyes at the words.
“She likes more when you’re rough, you’ll see,” Katsuki scoffs.
“Is that right?” Izuku turns to you with a knowing smile. “Be honest,” he encouraged you, fingers massaging your tender skin.
You bit your lip.
They both knew the answer.
They were waiting for yours.
Hoping you’ll slip. Hoping they can punish you.
But you saw it coming already.
“I— uhm— yes,” you reply with the tiniest bit of shame.
His hands squeeze your hips as he brings you upward, making you whimper when his tip nudges your sensitive clit, your whole body jolting at the contact.
“Let’s see then,” he muses, frowning slightly as he aligns himself at your wet entrance.
You take a deep breath, hands digging into his shoulders, while he sinks you down his length, a cry tearing out of you at the stretch. It was big. And it burned. Yet it felt heavenly.
He watches closely as you swallow him whole, pussy lips molding perfectly around him. He can see how Katsuki’s cum and your juices are dripping all over his base, the pressure of him inside you, making all of it gush out helplessly.
“Sorry ’bout that,” Izuku lets out a breathy laugh.
“’S okay, she has other holes to fill,” the blond says, shaking his head as he watches you take Izuku.
“Mhm— I— Ah!”
You moan loudly, eyes squeezing shut at the feeling of his girth scratching and stretching your walls, making your legs shake.
“M-move,” you stutter. “Please, Izuku,” you add, looking at him with pleading eyes.
“You’re so mannered, baby,” he smiles softly, dragging himself out of your abused hole, then shoving his dick back in.
The feeling of him buried deep inside you made your stomach clench.
Izuku’s hands squeezed your hips tighter, holding you steady, creating his own rhythm.
“…you feel so good,” he murmured, his voice low and rough.
Your back arched involuntarily, pressing into him as you gasped, legs trembling. “Yes…yes…” you moaned.
He leaned closer, lips brushing your ear. “Look at you… so eager,” he whispered.
Your words were replaced by long moan when you felt him shift under you, pushing you just right on his cock, hitting your sweet spot. Every movement made you whimper. Every stretch made your eyes roll to the back of your head.
Your legs shook as he pushed deeper, his girth making you squeeze him. You gasped, unable to control the pleasure building inside you. “Please… don’t stop,” you whispered, voice barely audible, shivering with need and anticipation.
“Stop asking…” he made a pause, as he shoved you down his dick once again. “… just take it,” he grunts in your ear.
Your back arched again, nails digging deeper into his shoulders, hips moving almost on instinct as your body responded to him.
You moaned his name helplessly, breath ragged, body trembling. The way he thrusted into you, the way he held you so perfectly, made your chest ache and your stomach twist with the need of release.
Izuku’s hand stayed pressed against your hip, holding you firmly. His gaze flicked towards the blond sitting quietly on the other side of the bed, arms crossed, jaw tight.
“Hey,” he murmured, voice silky and smooth, “don’t you feel bad for Kats?”
You froze, breath hitching as your eyes followed his.
“Look at him,” Izuku continued, tone teasing but cutting. “He’s getting nothing right now… while you sit there, enjoying yourself…”
Guilt hit through you instantly. You could feel his eyes on you, studying your reaction.
Katsuki’s sharp voice cut through the haze, blunt and impatient. “Oh, yeah… your mouth’s free,” he said, eyes narrowed, having a nasty glint to them.
“And you’re not using it for anything other than moaning. Use it for somethin’ else, won’t ya?”
Your body jerked at the words. He wasn’t yelling exactly, but the bite in his tone made your stomach tighten.
“C’mon,” he growled, shifting slightly in his seat, eyes still locked on you. “Don’t just sit there squirming. You’re good at this, aren’t you?“ he reminded you as his hand palmed his dick.
You shivered under his gaze, heat rushing to your cheeks. Your hands clenched, yet your body was already responding. Still seated in Izuku’s lap, facing him, you twisted your torso so you could also see Katsuki.
Katsuki’s eyebrows raised at the quick gesture, but his shock didn’t last long as a smirk spread over his lips.
“See how fast she’s responding?” he laughed mockingly as he rose from his seat and came closer to where you and Izuku sat.
His knees hit the frame of the bed as he stopped in front of it.
You saw Katsuki’s hand rise and tangle in your hair, forcing you to look up at him. You watched as he gave his member a few pumps with the other hand before guiding it in your direction.
“C’mon then, open up,” Katsuki said impatiently, pushing your face towards his dick, not caring that you were still struggling to take Izuku’s.
You parted your lips slightly, sticking out your tongue, and he chuckled.
“Wide open. You know I’m bigger than that.” He laughed, Izuku snickering quietly as well.
Katsuki slapped his dick against your tongue, not waiting long before shoving it down your throat, making you gag around him.
Izuku didn’t let you adjust to the intrusion as he thrust into you harder than before, making your whole body shake violently. Even if he had wanted to slow down, your greedy pussy dragged him right back, swallowing him whole.
You tried to steady yourself using Izuku’s shoulders, even though your breath was ragged, your eyes barely open, and your jaw aching from how wide you had to open for Katsuki.
You began bobbing your head, your tongue enveloping his member, dragging over his tip, but the pressure in your belly was close to snapping.
You desperately patted Izuku’s shoulder, hoping he would slow down his movements, but all he did was smile widely at your gesture.
“Wanna go faster? Is that it?” he asked, confused, his sweet tone sounding faker than usual. He wasn’t even hiding it anymore.
That freak.
You tried shaking your head, but Katsuki’s hand kept you still, making sure you were unable to do anything else. The muffled sounds that escaped you didn’t help either.
Izuku’s hands dragged you over his dick— up and down— until you were barely able to keep your mouth closed around Katsuki’s member. You rolled your eyes to the back of your head as Izuku practically abused that sweet spot inside you, causing your orgasm to wash over you in waves, leaving your body completely numb.
Izuku’s hands left your hips and your grip on his shoulders loosened until you fell onto your back on the mattress, your chest rising and falling at a rapid pace, your body trembling.
Your vision blurred for a few moments but readjusted slightly as you saw Izuku’s figure looming over you, green curls sticking to his forehead. He was saying something to you, but you were so out of it that you couldn’t even hear him.
Then you jolted.
When you looked down, you saw Katsuki’s cum spreading all over your naked breasts in hot spurts, as he had had to finish the job himself. He made sure to cover everything in that sticky, white substance, leaving no skin visible to the eye.
“Told you she likes it rough,” Katsuki’s laugh cut through the room.
Izuku gave him a nudge as he looked at you again.
“…are you up for one more?” he asked, giving an apologetic smile.

Katsuki Bakugou has a best friend problem.
And it isn’t the kind of problem that can be solved by just talking about it, like normal friends do.
No. This is pretty difficult to solve.
Why?
One, because Katsuki doesn’t even talk about feelings or problems most of the time. He just bottles them up until something new appears and then forgets about whatever bothered him before.
And two, he definitely won’t talk about how a wet dream with his best friend made him feel.
Yeah. A wet dream.
He hasn’t had one of those since he was a fucking teenager, and it makes him feel so stupid. He is a grown man, for God’s sake. An established pro-hero. A respected one. And more recently?
A fucking loser.
A loser who now struggles to even meet your eyes while you’re having a simple conversation, because every time he does, he remembers how you looked in his dream — naked and sweaty and so fucking eager to suck him off.
And of fucking course his mind wanders further—
Would your mouth feel that good in reality?
Would it turn him on that much to have you on your knees between his legs?
Would your moans really sound that divine while doing your best to bring him towards pleasure?
Will—
“Earth to Katsukiii,” you suddenly speak, waving a hand in front of his face, pulling him out of his thoughts and making him jolt slightly, his body shifting backwards on the couch.
“What!?” His head snaps towards you instantly, his hand coming up to slap yours away, ignoring the warmth that lingers from the brief contact.
“I have been talking to you,” you frown, scooching closer to him, leaning forward slightly, trying to catch his gaze. “What’s the matter?”
“Nothin’,” he shrugs, but his body tenses the moment your chest brushes against his arm.
“You’re even pissier than usual,” you remark with a raised brow, studying him carefully. He scoffs.
“You’re imagining things,” he replies way too fast.
You frown deeper, squinting your eyes as you shift even closer, intentionally closing the space between you. You don’t miss the way he immediately leans away.
“Why do you run from me?” you ask, tilting your head.
“I like my space, weirdo,” he mutters under his breath.
“I like your space too,” you tease, nudging your knee against his.
He instantly moves his knee away.
“Shut up and watch this damn movie,” he rolls his eyes, trying to focus anywhere but you.
“Kats.”
No answer.
“Katsuki,” you insist again, leaning in and poking his cheek with your finger.
You feel it — the tension.
You notice the way his hands curl, palms balling into fists as he takes a slow, deep breath, clearly trying to keep himself together.
“What’s up with you?” you push again, your voice softer this time, but more insistent. You move even closer, until he’s practically cornered at the end of the couch, your body fully pressing into his.
“Tell meee,” you drag out, nudging him lightly. “What’s bothering you?”
“You’re bothering me,” he finally snaps, his tone sharp and annoyed, making you blink in surprise. “Even in my fuckin’ dreams,” he adds with a frustrated groan, dragging a hand through his hair, making it messier than it already was.
“What?” you ask, caught off guard. “You dreamt about me?”
“Are you deaf?” he rolls his eyes, letting out a short, dry chuckle.
Then—
Something shifts.
A slow, almost mischievous grin spreads across your lips.
“What kind of dream did you have?” you ask, lowering your voice slightly as you lean closer, your gaze locking onto his.
Before he can react, you move.
In one smooth motion, you swing your leg over him, then the other, settling yourself directly in his lap, your thighs resting on either side of his muscular legs.
His mouth parts slightly, frozen halfway open, one eye twitching as he stares up at you, completely caught off guard.
“Come on,” you push again, shifting slightly on his lap, your clothed core brushing against his crotch through his jeans.
“Did you have a wet dream?” you ask playfully, clearly teasing, not thinking anything of it — but the moment he flinches, looking away instead of snapping back at you, your smile falters just a bit.
“Did you really have a wet dream of me?” you ask again, this time more serious, your eyes searching his face.
“Piss off,” he mutters, avoiding your gaze.
“Oh my god… I want to know right now,” you nudge him again, more insistent this time.
“I ain’t telling you shit, now get off of me,” he says, though his hands find your hips, gripping them instinctively.
You place your hands over his, pressing them down, smirking slightly.
“You know… if you tell me what it was about… maybe I can help,” you shrug casually, as if you didn’t just drop that.
He stares at you, completely dumbfounded, like you just said the most insane thing he’s ever heard.
“You gotta be joking,” he says, forcing a smile that doesn’t quite reach his eyes.
“Why would I be? It’s not like I don’t find you hot or anything,” you add, shifting slightly again in his lap.
That stirrs something in him.
He hisses under his breath, his grip on your hips tightening without him even realizing it.
“I’m still not telling you,” he mumbles, jaw clenching.
“Okay…” you hum. “I’ll guess.”
You take a moment to think, then—
“Was I on all fours? Were you fucking me from the back? I know you like doggy style… or maybe something else? Like missionary? Or cowgirl?” you ramble, mostly to yourself, watching his reactions closely. “How about—“
“It was a goddamn blowjob, now shut up,” he groans, his head falling back against the couch with a dull thud.
“Oh,” you pause, blinking. “A blowjob,” you repeat thoughtfully, tilting your head slightly.
“How was I able to fit all of that in my mouth?” you add, genuinely thinking about it.
He groans louder this time, hands leaving your hops and dragging them down his face.
“You are killing me, woman,” he mutters, voice strained, making you giggle softly.
“So you want it?” you ask, watching him closely.
He makes a pause, completely baffled.
Then—
“The hell? Who asks their best friend to suck them off?” he snaps, glaring at you.
“Who dreams of their best friend sucking them off?” you shoot back instantly, raising a brow.
“Smartass,” he scoffs.
“Pervert.”
“Oh, I’m the pervert? Not you, who’s been grinding on me for the past minutes?” he shoots back.
“I only suggested it because you seem stressed lately,” you say, your tone softer now, but still teasing. “And you clearly don’t wanna talk about feelings. Maybe I can help some… other way… you know?”
He goes quiet.
Really quiet.
His brows pull together as he stares at you, his expression shifting into something more serious, more conflicted — something you can’t quite read.
You’ve never seen that look on him before.
Not like this.
There’s hesitation.
Something heavy sits behind his eyes.
“You better not make me regret this,” he mutters finally, his voice lower now.
Your brows lift slightly, tilting your head. You didn’t know what to make of this words.
“Wha— what?”
His hands tighten on your hips, making you shift against his crotch for the nth time.
“Get on your knees.”
“Now?” You ask baffled.
“Yes, now. I’m in the mood and it’s your fault,” he reminds you.
You bite your lip to repress a smile.
Instead of a snarky comment, you just nod quietly and get off his lap. He spreads his legs wider the moment you move, watching you closely as you lower yourself onto your knees, settling between his muscular thighs.
Your palms come up to touch them, fingers gripping the material of his jeans as you slowly move them up and down, feeling the tension in his body, trying to ease it just a little.
You take your time.
Slowly moving upward, dragging it out, making it feel like it takes forever to reach his crotch… then his belt.
You start unbuckling it, your movements slow, all while looking up at him — watching the way he stares down at you, jaw tight, lips pressed together, hands resting stiffly at his sides.
You slide the belt out of the way, then undo his zipper, finally revealing his black boxers. Something hard brushes against your hand and he hisses above you, his breath catching.
Your fingers dip under the material and drag it down, exposing his happy trail that leads down to his cock. His own hands come down to help, pushing his jeans and boxers lower, lifting his hips just enough. The fabric bunches at his thighs, out of the way.
And then—
His cock springs free.
Long. Thick. Prominent veins running along the length of it. The tip flushed a reddish color, already leaking with pre-cum.
“C’mon, dig in,” he mutters, a smirk tugging at his lips as his hand comes to tangle in your hair, pushing you slightly forward.
You don’t rush.
You lean in slowly, pressing soft, open-mouthed kisses along the sensitive skin, feeling the way he reacts instantly — his breath hitching, a quiet hiss slipping past his lips as you glance up at him through your lashes.
Your tongue slides out, dragging along his length, long, intentional strokes, collecting the pre-cum as you go. His fingers tighten in your hair.
“Don’t— be such a tease, damn it,” he grits out, voice rougher now, the veins in his neck more visible as he looks down at you.
You let out a quiet chuckle, but you give in.
Enough teasing.
You part your lips and guide him in, taking him into your mouth slowly, inch by inch, relaxing your jaw as you go, until the tip presses against the back of your throat.
You pause there for a second, breathing steadily through your nose, adjusting — letting your body relax around him.
Then you start moving.
Slow at first.
Pulling back just enough before taking him in again, setting a rhythm, your tongue flattening along the underside, tracing the veins, working with each movement.
Spit and pre-cum mix together, making everything smoother, your lips sealing tightly around him.
All the while, your eyes stay on him.
Watching everything.
The way his teeth catch his lower lip. The flare of his nostrils. The crease forming between his brows as he tries to hold himself together. Low grunts slip past his lips, restrained, controlled — but you can tell he’s holding back.
That only makes you pick up the pace.
Your head starts bobbing more steadily, your movements more confident, more precise. Tears sting lightly at your eyes from the burn of your throat, but you don’t stop — you just adjust your breathing, keeping the rhythm consistent.
You want to hear him.
Really hear him.
“You happy now?” he asks, breath uneven, voice rough. “Having a mouth full of me?”
You let out a muffled moan around him in response, the vibration traveling through him as your tongue moves again, your pace never faltering.
“You greedy brat,” he chuckles, though his voice strains. He knows you — you like this, like putting on a show, like pulling reactions out of him.
His hips twitch upward when you increase your speed, your nails digging slightly into his thighs to steady yourself as his fingers tighten in your hair.
Sweat starts to bead at his forehead, sliding down as strands of blond hair stick to his skin.
“Mhm— keep— keep going,” he finally groans, his control slipping just a bit more.
You keep the same pace, consistent, precise, working him up without losing rhythm, your tongue and lips working together, spit and pre-cum already dripping down your chin. But is all worth it when you feel it—
The twitch.
The tension building.
A few more precise movements, a slight change in pressure, and then—
He breaks.
“Fuck, fuck, gonn a—“
His words are cut off as a low, deep moan escapes him. He releases, his body tensing as he spills hot loads of cum into your mouth. He closes his eyes at the feeling, barely able to keep his lips sealed.
For a moment, he doesn’t move, his orgasm washing over him, then — he finally looks at you. You were still on your knees, still sucking and slurping like your life depended on it.
“Fuckin’ hell— you’re takin’ everything,” he lets out a weak, breathy laugh. And it was true, you make sure to not let anything go to waste.
You suck him dry.
And he lets you — for a short while.
Only when the sensitivity kicks in does he tug at your hair, trying to catch his breath and helping you catch yours.
“Shit— too much—” he groans, needing another second to breathe, to recover as you pull away, licking your lips slowly, cleaning the corner of your mouth with the back of your hand as you look up at him.
Taking him in.
He’s leaned back against the couch now, hair messy, chest rising and falling steadily, his cock flushed and glistening, resting against his stomach now. His pants and boxers are still pushed down around his thighs as he spreads his legs, taking a lot of space like usual.
But he wasn’t the only one looking messy… he noticed your state too.
And fuck if it wasn’t the most beautiful thing he’s ever seen.
Your hair was deshiveled from his grabbing, your cheeks were flushed, lips plump and glistening with fluids… you looked so fucking pretty like this — on your knees for him, having his cum down your throat and looking at him with teary eyes — a sign of how hard you tried to take him.
You remain on the floor even if it wasn’t the most comfortable place, still close to him.
“So…” you finally break the silence softly.
His eyes snap back to yours, still catching his breath.
“Was this better than your dream?” you ask with a raised brow and a teasing grin.
But he won’t give you want to want. He already gave you enough.
He just scoffs at your question, rolling his head slightly to the side, trying to hide his smile.

iys a nagi x reader here on Tumblr reader is nagis personal assistant and just got her 12 week break cut short to 6 weeks now she's back at bllk. She has a roommate and nagi always asks her for snacks. I was about to read the smut part then I lost the fic cause I closed the tab. Also I remember everyone has separate rooms unlike cannon
you swore it was just a dare. that this was supposed to be a joke, something to laugh about with your friends. but when the campus loser had you pinned to the sheets under him — his ridiculously huge cock grinding against all the right spots — it was getting harder and harder to remember how you ended up here in the first place.
each thrust felt like it was stripping away every ounce of control that you desperately tried to cling onto, unraveling you further when his pelvis met the curve of your ass.
“oh—fuck!” you cried, gripping onto the sheets helplessly. the sight of him hovering above you was almost unreal, caged in between his arms. this was the loser you got dared to sleep with? his cheeks were flushed in a light shade of pink, sweat beading on his temples before falling onto your skin. his hands were wrapped around your waist perfectly, holding you in place while he mercilessly drove into you. “you sure this—nngh—is your first time?” every word you managed to get out took effort, coming out in between choked cries and whines.
“mmm, does it look otherwise?” he rasped, his breath ghosting your collarbone before biting down on your skin. “you’re shaking so much.. wasn’t expecting a loser like me to be this good? good thing you decided to come see for yourself, hm?”
you could hear the faint cockiness dripping from his tone, unbothered and apathetic as he filled you up with languid strokes, leaving you clinging onto his shoulders. it was almost humiliating how effortless it was for him to completely ruin you, submitting to him fully and abandoning your pride. fuck this loser shit. no one’s held you like this before, no one’s fucked you like this before. “you know.. people call you a loser.” you said in between gasps, wrapping your arms around his neck to keep him close.
“haah—does it matter?” groaning into your skin, he melted into your warmth, the brutal rhythm turning into something that bordered on intimate. “not anymore.” you shook your head. “i’m starting to want to keep you to myself.”
“you sure you won’t get bored of a loser like me?” he asked, leaving open mouthed kisses on your neck. “i don’t come with much, just saying.”
“does it matter?” echoing his words, you pulled him in for a kiss with your legs wrapped tight around his waist. “if i want something i must have it. and in this case.. i want you.”
his gaze lingered on yours, looking closely. unyielding. like he didn’t want to look away, like he was looking for the slightest bit of hesitation — a sign of deceit. but there was none. gone was the lie — the trap he knowingly walked into — unarmed the moment he held you in his arms.
“sure. you can use me, play with me, tell your friends whatever you want..” he murmured, hot breath hitting your ears. “but next time, don’t wait for a dare.”
you always thought nagi was clingy, but nothing could’ve prepared you for having a son who looked exactly like him—and somehow acted even worse.
your little boy had his own room, decorated perfectly with his favorite things. soft walls painted his favorite color, shelves lined with toys, a big plush bed with a comforter that matched his tiny personality. you thought he’d be excited to have his own space, finally able to call a room his own. but no matter how many times you tucked him in there, kissed him goodnight, and told him sweet dreams, he always ended up sneaking into your room in the middle of the night.
“baby, you have your own room,” you’d tell him, already half-asleep as he wriggled between you and nagi, clutching his stuffed toy and rubbing at his tired eyes.
“don’t like it,” he mumbled against your arm, voice muffled but determined. “smells better here. smells like mama.”
from behind you, nagi let out a sleepy chuckle, his voice low and raspy from just waking. “he’s got a point.”
“sei, you’re not helping,” you grumbled, carding your fingers through your son’s messy white hair.
“‘s true, though.” nagi’s arm lazily tightened around your waist, making sure he had his spot secured as well.
and just like that, your bed became home base for not one but two velcro boys. nagi’s long arm always thrown lazily over both you and your son, as if he was reclaiming his territory, while your son’s tiny hands refused to let go of your shirt, even in his sleep.
mornings weren’t much easier. you usually woke up pinned—your son starfished across your chest, drooling into your shirt and snoring softly, while nagi coiled around your waist like a human-sized snake, his face buried in your neck and his breathing steady.
“mamaaa, don’t go,” your son whined when you tried to sit up, still half-asleep but immediately aware of your movement.
“stay, babe,” nagi muttered in the exact same tone, tightening his hold without even opening his eyes.
you groaned, flopping your head back against the pillow. “if i don’t get up, who’s going to cook breakfast?”
“delivery…” nagi mumbled without missing a beat.
“delibewy!” your son chirped, copying his dad perfectly, lips curling into a sleepy grin.
you sighed, staring up at the ceiling. “i’ve basically got twins.”
in the kitchen, it wasn’t any better. nagi leaned against the counter, watching you cook with hooded eyes like it was entertainment, while your son clung to your leg like a koala, making it nearly impossible to move from one counter to another.
“hungryyy,” nagi dragged out the word, his voice pitched just enough to sound pathetic.
“hungryyyyy,” your son echoed immediately, tugging at your shirt dramatically, as if he hadn’t eaten in weeks.
you pinched the bridge of your nose. honestly, you didn’t know who needed actual attention more—your real baby or your oversized one.
by the time you managed to herd them into the living room, you thought you’d get a break. wrong. the moment you sat on the couch, nagi sprawled across your lap, long legs dangling over the side, head pillowed comfortably on your stomach. then your son came toddling over, climbing up onto the little sliver of space left, determined to wedge himself in.
“mama’s lap is mine!” he huffed, pushing at nagi’s side with his tiny hands.
“hey, don’t copy me,” nagi muttered, refusing to move and tightening his grip around your waist like a stubborn child.
“i copy you,” your son shot back smugly, puffing his cheeks in victory.
you looked between the two of them, their matching pouts making your head spin. it was like staring at a smaller, louder version of nagi arguing with the original. “see what you’ve created?” you glared at nagi over your son’s head.
“pretty cute, though,” nagi replied, utterly unbothered, even as your lap circulation slowly began to suffer.
errands were a whole new battlefield. dragging nagi out of the house was already hard enough, but with your son, it became a parade of clinginess. nagi shuffled along beside you, dragging his feet with a bored look, while your son waddled on your other side, clinging tight to your hand and swinging it back and forth.
“do i have to go?” nagi whined.
“yes.”
“me too?” your son parroted, looking up at you with big pleading eyes.
“yes, you too,” you said firmly.
at the grocery store, it got worse. nagi leaned heavily against the cart like he might collapse if he had to stand on his own, while your son sat inside with his arms folded across his chest, mimicking his dad’s pout. both of them gave you identical lazy stares as if shopping was the most exhausting thing in the world. passersby gave you sympathetic (or amused) looks—like you were wrangling not one child but two.
finally, bedtime rolled around again. you tried once more to settle your son into his room, tucking him under his blanket with kisses on his forehead. he smiled sleepily, promised to stay this time, and even hugged his plush a little tighter like he meant it. but by 2 a.m. you felt the mattress dip and a tiny body crawl between you and nagi again.
you opened your eyes just in time to see nagi, half-asleep, lifting the blanket to let him in like it was the most natural thing in the world.
“sei,” you whispered, watching your son curl against you with his plushie, sighing as his small fingers immediately latched onto your shirt again. “you’re spoiling him.”
“he just wants you,” nagi shrugged, his voice thick with sleep as he pulled you both closer with one arm. “same as me.”
“mama’s mine,” your son murmured into your chest, already halfway back to dreamland.
“no, mine,” nagi countered softly, pressing his face into your neck with the faintest smirk.
you sighed, trapped between your two velcro babies—one small, one oversized, both equally stubborn. exhausting? yes. overwhelming? definitely. but as their warmth surrounded you and their breathing evened out in sync, you realized you wouldn’t trade this for anything.
your life now was full of clinginess, mimicry, and a whole lot of patience. and honestly? it was perfect.
nagi seishiro notices two things the first time he sees you: you’re beautiful, and suddenly leaving seems like too much work.
anri has always been the ambitious one between the two of you.
even growing up, while other kids were still deciding what they wanted to be when they grew older, your sister already seemed to have a clear picture of it all mapped out in her head, talking endlessly about football development programs and youth leagues and how japan needed something better— something stronger— to compete with the rest of the world.
you used to listen from across the dinner table, chin resting lazily in your palm while she went on and on, the passion in her voice so genuine it was hard not to admire it, even if you didn’t quite share the same dream. not entirely, anyway.
because while anri loved football for the strategy, the players, the idea of building something revolutionary out of raw potential, you had always found yourself fascinated by a slightly different part of the sport— the human side of it, the way bodies moved and endured and sometimes broke under pressure, the quiet science behind stamina, recovery, injury, and resilience that most spectators never thought about while cheering from the stands.
which, unsurprisingly, is how you ended up buried under textbooks and late-night study sessions as a sports medicine student, learning about muscle fatigue and joint stability and the delicate balance between performance and damage that every athlete constantly walked.
it isn’t glamorous work, not really.
there are no roaring crowds or championship trophies waiting at the end of a long night of memorizing anatomical diagrams, only the quiet satisfaction of understanding how the human body functions under strain, how a torn ligament can end a career just as quickly as a moment of brilliance can start one.
still, it’s a field you’ve come to love in your own quiet way.
so when anri calls you one afternoon, her voice buzzing with the kind of excitement that usually means she’s about to rope you into something slightly insane, you probably should have expected where the conversation was heading.
“you’re studying sports medicine, right?” she asks, barely giving you time to greet her before launching straight into it.
you lean back in your chair, phone pressed between your shoulder and ear as you absentmindedly flip through your notes.
“last time i checked, yeah.”
there’s a pause on the other end of the line, brief but loaded with anticipation.
then—
“how would you feel about seeing the inside of a professional training facility?”
the question hangs in the air for a moment, vague enough that you almost laugh it off at first, assuming she’s talking about some local club or youth program she’s been working with lately.
instead, anri exhales softly and says a name you’ve only heard mentioned in passing, always accompanied by a strange mixture of excitement and disbelief.
blue lock.
she goes on to explain it quickly, words spilling over each other as she describes the massive training program currently housing japan’s most promising strikers, a project led by a man named ego jinpachi whose methods are, according to her careful wording, “a little unconventional.”
from what you can gather, unconventional might actually be an understatement.
still, the opportunity she’s offering isn’t quite what you expected.
you wouldn’t be a full staff member, of course— just assisting the performance team for a short period while you continue your studies, helping with routine physical monitoring, keeping track of fatigue levels, making sure none of the players are quietly destroying their bodies in the middle of ego’s relentless training regimen.
nothing too complicated.
mostly observation, basic evaluations, and documentation.
experience, anri calls it.
and maybe, she adds after a moment, a chance to see football from a perspective you’ve never quite experienced before.
looking back now, you probably should have asked more questions before agreeing.
after all, nothing about blue lock is ever quite as simple as it sounds.
because by the time you reach the final name on your list, the day has already stretched longer than you expected.
the first day inside blue lock had been exactly as overwhelming as anri warned it might be, filled with introductions, confused glances, and far too many boys with competitive streaks sharp enough to cut through the air of every room you stepped into. one after another, you’d moved through the facility with your tablet in hand, checking vitals, logging notes, answering questions— some curious, some suspicious, some bordering on outright disbelief that someone like you had suddenly appeared in the middle of their striker battlefield.
most of them had eventually settled once they realized you were just there to do your job.
a few had tried to show off.
a few had complained.
and one or two had stared a little too long before remembering they had reputations to maintain.
still, the day had passed quicker than you expected, your list slowly shrinking as one name after another was checked off your tablet, until only a single player remained scheduled for your rounds.
you pause outside the training room for a moment, glancing down at the screen.
seishiro nagi.
the name is familiar, though only vaguely. anri had mentioned him briefly when you’d asked about the players earlier, something about ridiculous natural talent and a playstyle that made even ego pay attention, though she’d also added, with a small sigh, that he was apparently “a little difficult to motivate.”
you assume that means stubborn.
or arrogant.
or both.
pushing the door open, you step inside.
the room itself is quieter than the rest of the facility had been throughout the day, most of the players likely having already moved on to their evening routines, leaving only the soft hum of the overhead lights and the faint echo of distant voices somewhere down the hall.
for a moment you think you might be alone.
then you notice him.
tall, pale, and half-sprawled across the floor near the edge of the mattress though someone had simply dropped him there and forgotten to pick him back up again, white hair falling lazily across his forehead while one long leg stretches out in front of him and the other bends slightly at the knee. his phone rests loosely in his hand, screen glowing faintly as his attention drifts somewhere between whatever game he’s playing and the quiet of the empty room.
you clear your throat gently.
“nagi seishiro?”
he hears his name.
barely.
the voice pulls him out of the comfortable haze he’d been floating in, thumb pausing mid-tap against his phone screen as his gaze lifts toward the doorway.
and for a second, the world tilts.
because standing there is someone he definitely hasn’t seen before.
you.
nagi blinks once, slowly, his mind taking an extra moment to catch up with what his eyes are already processing, the unfamiliar shape of you framed by the doorway, tablet tucked against your side, strands of hair slipping slightly out of place from what must have been a long day walking around the facility.
pretty.
the thought arrives in his head with the same casual clarity as noticing the color of the sky.
just a simple observation.
pretty.
his gaze lingers without much urgency, drifting over the small details almost lazily, the soft crease between your brows as you glance down at the tablet in your hand, the faint tiredness around your eyes, the way the light catches briefly against your hair when you shift your weight.
he doesn’t realize he’s staring.
doesn’t realize you’ve already started speaking again.
something about a routine checkup.
something about muscle fatigue.
something about your role in the facility.
the words reach his ears and promptly dissolve somewhere in the space between hearing and understanding, his attention still caught on the quiet realization that the person standing in front of him might genuinely be the most interesting thing he’s seen all day.
“…so if you could just sit up for a moment—”
nagi doesn’t move.
doesn’t respond.
doesn’t even blink.
from your perspective, it very much looks like he has simply stopped functioning.
you pause mid-sentence, confusion flickering briefly across your face before it slowly transforms into something far less patient.
“…hello?”
nothing.
a small sigh escapes you as you lower the tablet slightly, free hand lifting almost automatically to sweep a loose strand of hair behind your ear, your expression settling into the kind of mildly irritated look reserved for people who clearly aren’t paying attention.
“nagi.”
that finally seems to reach him.
his eyes refocus slightly, like someone returning from a very distant train of thought, blinking once before looking up at you again.
“…huh?”
you stare at him.
he stares back.
for a moment neither of you say anything.
then you inhale slowly, patience wearing thin as you tilt your head just slightly, gaze sharp.
“were you listening to anything i just said?”
nagi considers the question.
honestly.
“…not really.”
it doesn’t take long for you to realize something about nagi seishiro.
more specifically, it doesn’t take long for you to realize that the word lazy might actually be an understatement.
at first you assume it’s just a first-impression thing, the kind of behavior that fades once someone gets used to a new routine. after all, the environment inside blue lock is intense enough that most players eventually adapt whether they want to or not.
nagi, however, does not appear to share that mindset.
if anything, the longer you know him, the more impressive his dedication to avoiding effort becomes.
the first time you ask him to sit up properly so you can check his pulse, he watches you for a moment with half-lidded eyes before slowly asking if it would still count if he just stayed lying down.
the second time you ask him to stretch his arm out so you can test muscle tension, he shifts it about halfway toward you and then stops, glancing at you like that amount of cooperation should be sufficient.
and the third time— somewhere during the third week of your rounds— he tilts his head slightly in your direction and asks if you could grab the water bottle sitting barely within arm’s reach because getting it himself would be, in his words, “kind of a hassle.”
you stare down at him for a moment, expression slowly flattening.
“…you’re so peculiar,” you sigh eventually, though the exasperation in your voice carries a quiet thread of amusement as you lean down to pick up the bottle and place it into his waiting hand.
nagi accepts it without hesitation, murmuring a quiet thanks before taking a drink like this entire interaction makes perfect sense.
which, over time, you begin to realize it probably does.
because despite how absurdly lazy he is, nagi never actually resists your checkups.
he doesn’t complain when you ask him to repeat stretches, doesn’t pull away when you press your fingers lightly against his wrist to measure his pulse, and never rushes you through the evaluations the way you initially expected someone like him might.
instead he simply sits there while you work, quiet and strangely patient, his pale eyes following the small movements of your hands as you jot notes down on your tablet or adjust the position of his arm.
at first you assume it’s just because staying still requires less effort.
it takes a little longer before you notice the pattern forming.
nagi starts appearing before you even call for him.
sometimes you’ll step into a quiet corner of the facility to finish your notes only to find him already there.
“didn’t i check you yesterday?” you ask once, glancing down at your schedule before looking back up at him with mild suspicion.
nagi hums softly.
“yeah.”
“okay.. then why are you here again?”
he thinks about it for a moment.
“…figured you’d be around.”
the answer is delivered with the same calm indifference he seems to approach everything with, like it isn’t particularly important either way, but your fingers still pause briefly against your tablet.
you clear your throat softly and gesture toward the mat.
“if you’re going to sit there, at least stretch your leg out properly.”
nagi does, though he takes his time about it.
over the next few weeks the routine settles into something oddly familiar.
nagi asks you for things that are very clearly within his reach.
you sigh, shake your head, and hand them to him anyway.
water bottles, towels, sometimes his phone when he’s dropped it somewhere inconveniently far from where he’s decided to lie down.
you always pretend to be annoyed about it.
he always asks anyway.
and as time goes by, the requests start coming with a little less distance between the two of you.
at first it’s small things.
nagi leaning closer while you check his pulse, resting his chin lazily against his hand while watching you write notes on your tablet.
then it becomes things like him shifting until his shoulder bumps lightly against yours while you’re sitting beside him on some bench, staying there like he didn’t even notice the contact happened.
the first time you try to move away, he follows without thinking. just a quiet shuffle closer.
“…nagi.”
“hm?”
“personal space.”
he blinks at you.
“…why?”
you stare at him for a long moment before sighing and going back to your notes.
after that he stops pretending it’s accidental.
sometimes when you kneel down to check the tension in his leg muscles, his hand ends up loosely resting against your shoulder like it belongs there.
other times he leans against your side while you write, the weight of him warm and heavy in a way that should probably bother you more than it does.
it’s difficult to scold someone who looks half-asleep while doing it.
still.
the real problem begins after matches.
because matches, are obviously one of among the many things that exhausts nagi.
one evening you find him sitting on the floor outside the training area, hair damp with sweat and shirt clinging faintly to his shoulders while he stares blankly at the wall like his soul has temporarily left his body.
you glance down at your tablet.
“did you finish your cooldown stretches?”
nagi tilts his head back slowly until he’s looking up at you.
“…m'too tired.”
“well. that’s not how recovery works.”
he hums softly.
then, without warning—
“carry me.”
you blink.
“…what?”
nagi lifts one arm lazily in your direction.
“…piggyback.”
you stare at him.
“no..?”
he watches you for a moment, as if considering the refusal.
then shrugs.
“…okay.”
you nod once, satisfied, before turning slightly to jot something down on your tablet.
that’s when two arms suddenly wrap around your shoulders.
a very tall, very sweaty, very heavy creature attaches himself to your back.
your brain takes a full second to process what just happened.
“nagi.”
“hm?”
“get off.”
he doesn’t.
instead he settles his weight more comfortably against you, chin resting near your shoulder like he’s discovered a particularly convenient piece of furniture.
“…too tired.”
“you’re literally covered in sweat.”
“…so.”
“so... that's gross.”
“shhh. don't fight it.”
“you are a six foot three man.”
“i think so, yeah.”
“that wasn't even a question— and i cannot carry you.”
he seems to think about that.
then—
“try.”
you open your mouth to argue again.
unfortunately, the moment you attempt to take a step forward proves exactly why this was a terrible idea.
because nagi seishiro is, in fact, a one six foot three demon.
your balance disappears instantly.
there’s a brief moment of silence.
then both of you tip forward, hitting the floor in an undignified heap.
your tablet skids across the mat.
you groan into the floor.
“uug— i told you.”
behind you, nagi lifts his head slightly.
“…it worked for a second.”
you push yourself up onto your elbows and glare back at him.
“you nearly crushed me.”
“…sorry.”
he does not look sorry.
in fact, he looks suspiciously comfortable lying on top of you and putting all of his weight onto you.
“you’re so heavy.. please get the hell off me.”
nagi reluctantly drops off to the side.
then, after a moment—
“can you still grab my water..?”
you stare at him.
then you start laughing despite yourself.
and somewhere in the middle of that ridiculous moment— sitting on the floor with a half-dead striker who just attempted to turn you into a pack mule— you realize something mildly concerning.
the quiet time you spend with him starts becoming the part of your day you notice yourself anticipating the most.
not that you’d ever admit that out loud.
still, it becomes increasingly difficult to ignore the small things.
the way nagi’s gaze lingers on you longer than it probably should.
the way he shifts a little closer whenever you sit beside him, like the space between you naturally belongs there.
none of it feels dramatic.
nothing about nagi ever really does.
whatever exists between the two of you grows the way most things around nagi seem to— quietly, lazily, almost accidentally, until one day you realize it’s been there for a while.
more than once now, when you step out into the hallway, nagi is already there.
you push open the door behind you and step into the hallway, adjusting the strap of your bag on your shoulder while your mind drifts lazily through the events of the day, already half-focused on getting home and finally resting your feet.
then you look up.
and there he is.
nagi stands a few steps down the corridor, tall frame leaning comfortably against the wall like he’s been there long enough to make himself at home. his hair is still slightly damp, pale strands sticking faintly against his forehead, and his shirt hangs loose from his shoulders like he couldn’t be bothered to fix it properly after training.
when he notices you, he straightens almost immediately.
not by much.
just enough that it’s obvious he’s been waiting.
“…hey.”
you slow to a stop.
“i thought everyone was still in the baths.”
nagi shrugs lightly.
“finished early.”
you narrow your eyes at him.
“don't tell me you skipped out. are you too lazy to even take a bath..?”
he tilts his head, considering the accusation.
“i didn't skip..”
you sigh softly, though the familiar hint of amusement creeps into your voice anyway as you walk closer.
“thank goodness.”
nagi doesn’t argue.
instead his gaze drifts slowly across your face, lingering just long enough to make you slightly aware of how closely he’s looking.
“you’re leaving?”
“i finished my rounds,” you explain, adjusting the strap of your bag slightly on your shoulder. “unless you’ve somehow injured yourself in the last ten minutes, my job here is done for today.”
“i could’ve...”
“you didn’t.”
“..okay, i didn't.”
the hallway grows quiet again.
nagi pushes himself away from the wall then, closing the small distance between you with that same unhurried pace he does everything with, until he’s standing close enough that you can feel the faint warmth of him beside you.
you glance up at him.
he’s already looking at you.
the kind of focused attention that makes your stomach tighten slightly before you can stop it.
“you look tired,” he murmurs after a moment.
you blink at him, adjusting the bag on your shoulder as you let out a small breath.
“i’ve been walking around this building all evening, nagi. ’course i’m tired,” you say, shifting the strap slightly higher against your shoulder where it’s begun to dig into the fabric of your sleeve. “and y’know… i’m still a student. blue lock’s just my part time thing for now.”
nagi hums softly in response, the sound low in his throat as his gaze drifts downward for a moment.
his eyes land on the bag hanging from your shoulder first, following the worn strap where it cuts across your arm like it’s been there all day, then slowly travel back up to your face again. you do look tired, he thinks, though not in the way he meant it earlier. it’s the kind of tired that comes from doing too many things at once— walking endless hallways, writing notes, juggling classes somewhere outside this place.
until now he hasn’t really thought about the fact that you leave.
that when the day ends, you don’t stay here the way everyone else does.
you just disappear out those doors and come back the next day like nothing happened.
you assume the conversation has ended there, so you shift your weight and step past him, already turning toward the end of the hallway.
nagi notices immediately.
before you’ve taken more than a single step, his hand lifts without much thought and catches the edge of your sleeve, fingers curling lightly into the fabric.
it isn’t a strong grip.
just enough to stop you.
you glance down briefly at where he’s holding onto you before looking back up at him.
nagi’s hand is loosely holding the fabric near your wrist, his fingers curled like he grabbed it without thinking too hard about it.
“…you’re coming back tomorrow, right?” he asks eventually.
the question is quiet.
but there’s something about the way he’s looking at you now that makes it feel a little less casual than he probably intended.
“of course i am,” you say slowly. “this is still my job.”
nagi nods once, a slow, thoughtful movement.
that’s good.
because the thought that you might not has crossed his mind more than once over the past few weeks, and every time it does it leaves behind a strange, restless feeling he doesn’t particularly like.
his thumb shifts faintly against the fabric of your sleeve before he realizes he’s doing it.
you seem to notice the movement too, your gaze flickering briefly toward his hand before returning to his face.
“were you waiting for me?” you ask.
the question doesn’t sound accusing. mostly curious.
nagi blinks once, tilting his head slightly as if the answer should be obvious.
“yeah.”
you stare at him.
“why?”
he considers the question for a second, though not very seriously.
from his perspective the answer is simple.
he finished early.
you usually leave around this time.
so he waited.
“..wanted to see you.”
the words leave his mouth easily, without hesitation.
and for a moment, you don’t respond.
to nagi it’s just another straightforward statement, no different from saying he’s tired or that training was exhausting today. but the reaction it causes in you is noticeably different.
nagi says it so casually that it takes a second for the words to actually settle in your mind, the meaning of them arriving a little slower than the sound. he doesn’t look embarrassed about it, doesn’t seem particularly concerned with how it might come across, and the calm way he’s watching you now makes it obvious that, to him, this is simply the truth.
like stating the weather.
like mentioning that training was annoying today.
he sees the way your expression shifts slightly, the small pause that settles between the two of you like something important has just been placed there.
“nagi,” you begin slowly, though you’re not entirely sure what you’re trying to say yet.
because the reality of the situation presses gently at the back of your mind.
blue lock isn’t a normal place.
the people here aren’t living normal lives, and you aren’t really part of their world in the same way they are. you come in during the afternoons with your bag slung over your shoulder, check a few vitals, write down your notes, and then disappear again once your rounds are finished, returning to lectures and assignments the next day and a future that probably doesn’t involve walking these hallways forever.
you’re temporary here.
and nagi— he belongs here.
which means whatever this strange little routine between the two of you has quietly become probably isn’t something you should let grow too much.
still.
“you can’t just wait around in hallways for people,” you say eventually, though there’s far less firmness in your voice than you intended.
nagi blinks.
“why not?”
the question is genuine.
you stare at him.
“…because it’s weird.”
he considers that for a moment, expression thoughtful in that slow, distant way he has when he’s actually thinking about something.
then his shoulders lift in a small shrug.
“didn’t feel weird...”
you huff quietly, shaking your head.
nagi’s gaze drifts over your face again, lingering in that same way you’ve started noticing more and more lately, the quiet focus of it making your chest tighten just slightly before you can stop it.
“…you’re always leaving when i see you,” he murmurs after a moment.
the observation catches you off guard.
“well, yes,” you say slowly. “that’s usually what happens at the end of a work day.”
nagi hums faintly, though he doesn’t look convinced.
“still annoying..”
your eyebrows lift slightly.
“annoying?”
“you’re the only interesting part of my day.”
the words land softly between you.
and suddenly the hallway feels much quieter than it did a moment ago.
you stare at him.
he doesn’t seem to notice the effect his statement has caused.
or maybe he does, and just doesn’t see why it’s a big deal.
because to him, it probably isn’t.
but your shoulders relax a little, a quiet laugh slipping out under your breath despite yourself.
“you really shouldn’t say things like that so casually.”
“why?”
“because people might misunderstand you.”
nagi tilts his head.
“…i don’t think they would.”
you sigh. (for what felt like the millionth time today) because for someone who seems so half-asleep most of the time, nagi has a very irritating way of being straightforward when it comes to things he actually cares about.
“you should go back before someone notices you disappeared,” you tell him gently. “and i should go home before i fall asleep standing here.”
nagi thinks about that.
then slowly releases your sleeve.
the fabric slips from his fingers and your arm drops back to your side, though you don’t immediately move away.
instead you stand there for another second, looking at him like you’re trying to figure something out.
nagi doesn’t mind.
he likes when you look at him like that.
after a moment you step backward, adjusting your bag again before finally turning toward the end of the hallway. "goodnight, nagi."
nagi stays where he is.
watching you.
you make it a few steps before glancing back over your shoulder, your eyes finding his almost immediately.
nagi notices the moment you do.
and something small but satisfied settles quietly in his chest.
because you did look back.
and tomorrow, when you walk through these hallways again with that bag over your shoulder and your tablet in hand, he’ll probably end up waiting here again without even meaning to.
so for now— that quiet, strange little routine between the two of you might just have to suffice.

You were too young, a little over three, to understand the day your mom brought home your little sister. You'd been secretly asking the universe for a sibling, someone to share everything with. Ask and you shall receive! But, you never knew just how much she would shape your life into what it is today, especially when it came to Katsuki Bakugo.

The Kingdom: Elementary School
Fourth grade is when you and Katsuki started to play after school together on a daily basis. Him and Izuku would come by and grab snacks from your mom while you went back to the park around the corner, playing pirates and super heroes with the other neighborhood kids. Every so often, your mom would ask for you to bring your sister along. You never minded, even though she was your baby sister in first grade. The boys would pick on her — lovingly, of course — to make her feel included with the rest of the pack. She loved being around you, cooing and giggling away as she'd hold your hand and squeal with delight.
One day at the park, she'd declared herself to be queen of the castle as she stood on the slide, proudly puffing out her chest with her hands on her hips.
"I am the queen, and what I say goes!" she pointed to you and Katsuki. "Sissy will be the princess and you will be our royal guard, Katsu!"
You chuckle. "Isn't the older sister supposed to be queen?"
She does her best impression of a royal laugh, projecting her voice theatrically. "Not in my land! It's my kingdom and if you don't like it, I'll send you to the brig!"
"You're confusin' pirates 'n princesses again,” Katsuki taunts playfully.
She stomps her foot on the slide. “Silence in my kingdom! Izu will be my knight!”
Katsuki pouts. “Hey! Why don’t I get to be the knight?!’
“Cause I say so! You’re the royal guard cause you’re tough. Izu is the knight because he’s brave!”
You can’t help but let out a loud ‘hah!’ at her comment. Your sister never failed to push Katsuki in the cutest ways. He probably was thankful to be an only child whenever you guys would go home for the day.
Katsuki huffs at her declaration, taking the challenge with stride. “Fine! I’ll show you who’s tough and be the best dang guard in the whole world.”
“Do I get a cool set of armor, queen?” Izuku asks, bouncing up and down at the bottom of the slide.
“Of course! Only the best armor and ponies for my royal kingdom.”
She sits and pushes herself down the metal slide, rocketing off the edge past Izuku and barreling toward Katsuki. She trucks into him at full force — but, being small, that force isn’t much for him to withstand.
“What the heck was that for?!” he yells while catching her before she hits the wood chips.
“A test of your toughness, Katsu! And you passed! You’re deserving of a spot in my kingdom,” she giggles, mashing his cheeks together with her tiny palms. He protests her closeness and tries to fight her off, setting her feet back on the ground while she’s wiggling in his hold. Watching the two of them act like siblings themselves always made you feel so warm and fuzzy inside, knowing your two closest friends also adored your sister as much as you did.
You meander over to grab her from him. “Alright, I think you made your point, queen. Your guard and knight have other duties to get to.”
She waves goodbye to the boys over her shoulder as the two of you stroll home for dinner. She gleefully remarks how cool they are and that she can’t wait to marry them someday.
You can’t help but giggle at the thought. “Both of them? Wow, all to yourself, huh?”
She pouts and whips her head upward. “No, sissy! We both get one!”
”Oh yeah? Because you’re the queen of the kingdom, you get to pick?”
“That’s right! They’ll have to fight to see who gets to pick you!”
You roll your eyes, shaking your head at the thought. You’re only ten years old, the thought of boys fighting over you was hilarious.
”Promise not to tell Izu, but I think Katsu would win that fight,” she whispers, tugging on your hand to get you to lean over closer to her face. “He’s taller and faster!”
The thought of marrying Katsuki flashes in your mind. You have zero clue what that even looks like, but you imagine him bringing you flowers on the playground or giving you a bite of his ice cream. A blush creeps over your cheeks and nose at the thought. Your sister catches your reaction and gasps dramatically.
“You like Katsu?!” she exclaims.
You shush her. “No! Don’t go yelling that!”
That’s a big fat lie. You liked him a lot, he was your favorite person, but you’re kids.
It’s just a harmless crush.
───
An Enchanted Afternoon: Elementary School
A week later, the four of you returned to the playground after school. Snacks from your pantry in hand, the bunch of you sit on the swing set to eat. Your sister seemed extremely eager today, more so than usual. Once you all finished eating, she demanded your attention.
"Gather 'round! Your queen summons you," she declares, arms raised above her head. You and the boys huddle around her.
"Katsu, go fetch flowers!" she orders as she points to a nearby patch of grass. "Zuzu, clear out the sandbox of any villagers."
There wasn't anyone else here today, so that job was easily done. Izuku doesn't say anything and smiles as he heads over to the sandbox as ordered. Katsuki is confused, nose scrunched and arms crossed.
"Why do I need to get flowers?" he asks, tapping his foot in the wood chips.
"Do you dare defy your queen?!" she shouts, grinning wickedly. He obliges, sauntering over to the grass to find a few spare daisies.
"What's all this for?" you ask, genuinely curious to her plans. She doesn’t answer you as she grabs you by the wrist, dragging you over to the sandbox.
A few minutes later, Katsuki comes back with a handful of daisies, picked and pruned clean of any dirt and weeds. Izuku stands on the edge of the sandbox patiently.
”Perfect! Katsu, Sissy, please approach your queen.”
You play along and stand in front of her with Katsuki. It’s amusing how small she is in comparison to the two of you, easily shadowing over her figure.
“With my knight as witness, I give the blessing to the princess and royal guard to be married forever!” she exclaims, waving her hands around to mimic casting a magic spell.
You're pretty sure she got that line from a princess movie, but that doesn't make the sentiment any less adorable. You begin to chuckle to yourself, smiling ear to ear before turning toward Katsuki. You're expecting him to be disgusted, repulsed by something so sickly sweet, but are shocked to see him standing with the flowers outstretched in your direction. He's biting his bottom lip and avoiding eye contact by staring directly at your feet.
"H-here," he whispers meekly, pushing the flowers into your hands. You've never seen him so shy before — that's usually Izuku's demeanor. His unexpected affection makes your little heart flutter in your chest.
"Thank you 'Suki," is all you can muster up the courage to say, your mind running blank on the right thing to say. It's just an imaginary scenario. It's not real, not like you're actually marrying him. Katsuki exhales, turning his back to you to hide his strawberry colored cheeks.
"Now you're together forever!" you sister raves, dancing on her tip toes with satisfaction.
Maybe that was the moment she bound you two together with some unknown magical force, or it was a mere coincidence. The sappy part of your young brain believed in fairytales and chose to believe she was weaving your golden string to him, binding you two for life.
───
Leftovers: Middle School
”Yo, brats! Come eat already so I can get the hell outta here,” Katsuki called from your doorway. He’d come by with leftovers from his mom for you and your sister, since your own mom was working later that day. The two of you were still…friends? You weren’t sure. Being in seventh grade and all, he started acting like you weren’t cool enough for him. He did the same to Izuku, starting to ditch the two of you for other kids in class to hang out with at lunch or walk home with. Did it hurt your feelings? Absolutely. But you didn’t own him, he was allowed to have other friends, even if it did suck to see him less outside of class.
“Coming!” you called back, skipping down the hallway with your sister in tow. She happily ran into the entryway, hugging Katsuki by the waist. She was taller now, but still much smaller than him as a fourth grader.
“Hiya Katsu!” she beamed up at him, rubbing her face against his uniform jacket.
He grunted, uncomfortable with her sudden affection and poking her in the forehead to release her grip. “Let go, squirt!”
He turned his attention to you as your sister finally let go of him. “Here, take these. I gotta get to practice.”
”Thank you! Tell your mom we said hi.”
“Yeah, whatever.”
You hand the containers to your sister as she wanders off to the table. Before Katsuki opens the door, you tap him on the shoulder.
“Hey, are you alright?”
He scoffs at your question. “Why wouldn’t I be?”
“You just seem distant lately. Wanna come by sometime for a movie marathon?” you ask, tilting your head and giving him a warm smile.
“We’re not kids anymore. Got better stuff to do.”
Ouch, that stung. Your smile fades away as you reply. “Well…I know. I just miss hanging out with you.”
“You have Deku an’ that other group of bitches you hang out with, ya don’t need me.” His harsh comment has notes of jealousy intertwined in his words. He goes to put his hand on the door again before you take a step forward to stop him.
“Kat, they’re not a replacement for you. You’ve got your own friends now too since you’re on the soccer team. You’re saying we can’t hang out 'cause we have different friends?”
He glares at you before pushing past you and pulling on the front door.
“Hey!” your sister shouts from the dining area. “Katsu, that’s not nice. My royal guard doesn't act like that!” She’s always thought of Katsuki as a guard since your elementary school playground days.
“Cut the shit! We’re not kids anymore!” Katsuki rebuttals with a growl of frustration.
He makes eye contact with you. “We’ve grown apart, end of fuckin’ story. Get over it.”
He slams your front door closed and leaves you standing in the entryway, your eyes stinging from the urge to cry. You feel a small gust of wind rush by as your sister is sprinting to the door, throwing it open and running outside without shoes on.
“Hey!” She calls after Katsuki again. “Get your butt back here, Katsu!”
He turns on his heel. “Hah?!”
She stomps on the ground, fists balled at her sides. “Apologize to her!”
Katsuki cackles, a little too manically. “For what, brat?”
“You’re being a mean jerk to her! She doesn’t deserve to be yelled at like that. Friends are friends forever, idiot!” she yells, her cheeks puffed and eyebrows scrunched together.
You can’t help but stifle a laugh at her calling Katsuki an idiot and turn your head to hide your amusement.
”That’s not who you are, Katsu. That’s not how you treat your princess!”
He pinches the bridge of his nose and screws his eyes shut in annoyance, exhaling dramatically. He locks his gaze on you, storming back up to the doorway. He roughly ruffles your sister’s hair as he passes by her as a pseudo apology. Katsuki sucks the air through his teeth and shoves his fists in his pockets as he stops in front of you.
“Look, m'sorry for yellin’, okay?” he sighs, kicking a foot against the pavement. “I'll come over Saturday, we’ll have that movie day ya wanted.”
"You don't need to if you feel forced to hang out with me." Your eyes shift to your feet to avoid looking at his reaction.
" S'fine. I'll be here at noon, don't pick anything lame."
With that, he turns to leave for a second time in silence. You watch him disappear around the corner and can't help but feel like a burden for asking him to make time for you. As if reading your mind, your sister shakes you out of the negative train of thought while walking back to the house.
“Don’t worry about him, he’s just being a dumb boy. That’s what my teacher says when boys are mean for no reason.” She grins a toothy smile up at you and grabs your hand. “Come on! Foods getting cold!”
Katsuki rounded the corner and waited to be out of sight before palming his face in anger. He had no idea why he said those things to you. None of it was true, especially that you’d grown apart. If anything, he was jealous of your friends and missed seeing you all the time. But he couldn’t bring himself to say so, like always. Ever since middle school started, he’d harbored some unknown rage inside of him that lashed out every chance it could. He hated it and didn’t know what to do to stop it — hence trying out for the soccer team, looking for an outlet for the pent up emotions in his body. Katsuki secretly hoped you wouldn’t end up despising him for it.
Even after all this time, he still thinks of you whenever he sees a patch of daisies. Maybe one day he’d be brave enough to tell you about it.

Running Late: High School
The front door to your home opens as Katsuki slips inside, kicking his loafers off by the door. Your younger sister peeks over the kitchen counter while spreading jam over her toast and nods in his direction.
"Hey Katsu, pretty sure she's still asleep upstairs," she calls, rolling her eyes. "I tried to get her up three times, maybe you'll have better luck."
It was hard to believe that she was already in her freshmen year of high school — shit, it’s crazy that you and Katsuki were seniors. The age of playground days and summer adventures went by in the blink of an eye.
He makes his way to the kitchen island, leaning over to mess up her hair. Some things never change. "Thanks, bean. I'll get her ass movin’."
“Stooop! You’ll mess it up!” She whines as she pulls away, fixing a few stray pieces of her fluffy mane.
“Ya look fine, don’t sweat it,” he compliments while heading for the staircase. He makes his way to your bedroom on the second floor. The door is surprisingly cracked open. He taps on the doorframe to grab your attention.
“Come in,” you call, lying on your bed facing the wall above the covers while scrolling on your phone. You presume it’s your sister until a soft kiss is planted on your cheek.
“Mornin’ sweets,” Katsuki whispers, rubbing your shoulder to turn you to face him. He sits on the edge of your bed beside you. “You wanna be late for our last first day of high school?”
You shift to sit up and drop your phone to your bed, reaching to cradle his face in your hands.
“No, I just wanted to steal a few kisses first,” you mumble as your lips quietly meet his. Katsuki places one hand on your cheek while the other lightly grazes your back. After a few moments, the two of you part with a soft smack. You stand and straighten up your uniform skirt, flattening a few of the panels to work out any stray creases.
“Do I look okay?” You ask, spinning around for Katsuki and showing off your uniform.
“Y’always look good,” he sighs, standing to his feet. “Let’s get movin’ before bean suspects somethin’.”
You hadn’t told your sister about your relationship with Katsuki. Sure, you guys had been friends since you were children and he’s always around…how would she know the difference?
The two of you patter down the hallway and skip down the stairs to the kitchen. Your sister is waiting for the two of you, arms crossed and tapping one foot impatiently.
“Finally! Get your damn shoes on,” she orders while pushing you toward the door. She does a double take at Katsuki while you’re putting on your shoes, raising an eyebrow at him. “Katsu…are you wearing lipgloss?”
Oops.
Katsuki’s searching for something to say as his face glows scarlet. He puts a hand on the back of his neck and turns away, grumbling while attempting to hide his embarrassment.
“Oh come on, you two," your sister huffs. "I knew you guys started dating months ago. You think I didn’t notice?”
You spin around to face her, cheeks puffed and eyebrows scrunched. “You never said anything?!”
She laughs, walking up to Katsuki and placing a hand on his shoulder.
“If you ever hurt her, Katsuki, I’ll knock your lights out. I know where you sleep,” she threatens, grinning mischievously. Katsuki pulls her into a headlock, ruffling her hair a second time.
“Deal, but I plan on stayin’ alive.” He lets her go, chuckling as he smooths out the pieces of hair he messed with. Seeing the two of them get along never fails to make your heart swell with joy. Katsuki has always treated her like his own sister — one that he could easily give back at the end of every day, anyways.
She turns with a pout and her hands in the air.
“You both have my blessing, you should know that. I didn’t marry you two in a sandbox for nothing!”
───
Today Was A Fairytale: Current Day
“It’s an honor to be doing this for a second time. You’re in luck, my vocabulary has grown exponentially since our sandbox days.”
There’s a wave of laughter through the crowd at your sister’s lighthearted joke. You can’t help but smile as Katsuki’s fingers dance across the back of your hand to regather your attention.
God, he looks so damn handsome in that tux. His usual wild hair is slicked back and tamed — an extremely rare sight. Carmine eyes stare back at you, full of devotion and excitement for this next chapter in your little fairytale.
“By the power vested in me, and these people as my witness, I pronounce you two as king and queen of the kingdom!”
Friends and family alike cheer and whistle as you and Katsuki intertwine, kissing each other for the first time as husband and wife. He spins you around and dips you low, kissing the tip of your nose playfully.
“I love you,” he mouths, a silent profession of adoratio, reserved just for you.
The two of you strut down the aisle to the dance floor in the reception hall, the DJ already queuing the first dance song. Katsuki gently tugs you by the waist, pulling you closer to him as he begins to sway side to side when the music begins to fill the room. You rest your head against his chest and get lost in the moment.
Right now, the world belongs to the two of you. Every worry, struggle and hardship is stripped away from your lives to give you the peace you deserve.
There’s one thought that lingers in your mind as you catch a glimpse of your teary-eyed sister watching you from the corner of the dance floor, latched onto Izuku’s arm for support.
She tied that golden string with an unbreakable knot.

“ugh, my head hurts so bad.” you whine, clutching at your temples while massaging them trying to relieve some of the stabbing pain.
“you're being dramatic, now c'mon and finish this set of questions.” katsuki mumbles gruffly, eyes flicking from his own notebook to you for a brief second.
you groan, huffing but picking your pen up again, fixing your glasses and reading the questions displayed on your boyfriend's laptop screen.
mumbling the answers under your breath softly, you start solving the questions again, katsuki's dorm room turning quiet except for the scratch of pens on paper and the sound of slow breathing.
you've been studying for- how long now? an hour? two hours? finals are a pain in the ass and even though you've both proven how competent you are as heroes, you still have to clear your third year exams to actually graduate.
katsuki's crimson gaze, framed by his own pair of framless glasses, flits over to you, taking in the way you bite your lip when recalling something, the way you scrunch up your nose when you get something wrong. the tiredness in your gaze.
he knows you've been working hard. you've taken it upon yourself to study properly and get the best marks you can. and you've made good on that promise. your screen time has gone down significantly, you're always revising something or the other and you keep pestering katsuki to explain topics to you.
you're putting in your best. and maybe overworking yourself. you're not used to straining your brain this much, and clearly its affecting you. he can see the wearniness in your body language, the worry in your eyes, the way you fidget with your pen cap while reading the next question.
“oi.” he calls out, voice soft but gruff.
“hm?” you ask, eyes landing on him.
“you wanna take a break?”
your mind is screaming at you to say yes, that you need rest, but your eyes flick over to the list of practice question on the glowing laptop screen. you don't have time for breaks.
“i think i should finish these questions, no?” you mumble, the exhaustion in your voice clear.
“you need a break.” katsuki reframes, much firmer this time.
“but-”
“no buts.” he cuts you off, gently pushing the laptop screen shut. “c'mere.”
you take your glasses off and gratefully scooch over next to him, breathing in the scent of caramel and something muskier as he wraps and arm around you and pulls you closer, postitioning you so that you're sitting between his legs.
his forehead drops to yours, and you both stay that for a minute, eyes shut, just revelling in the warmth of each other's bodies.
“you're doing so good, doll.” he murmurs softly, placing a gentle kiss on the space between your eyebrows.
you smile softly at the praise, pressing your own kiss to his cheek, which leaves a shiny smear against his skin.
he doesn't complain, just grunts as he feels the sticky essence against his skin. you giggle softly at his reaction and he relaxes just a little.
“someone's enjoying themselves, huh?” he teases.
you press another glossy kiss to the tip of his nose. “mm hmm.”
his lips twitch up in a small smile and you take that as a cue to keep going, peppering shiny, sticky pecks all over his face, giggling as you place kisses on every inch of skin.
at least you feel better now, katsuki thinks. he can wash the stickiness off of his face later (or not), but for now, seeing your eyes light up like this was the only thing that mattered.
his smart little girlfriend deserved a little break, did she not? and if kissing him into oblivion was the break she needed, he wasn't complaining.

somno with katsuki just made sense. he’s always busy and you love your sleep. he’s up early in the mornings to train and then gets home late from patrol. you try to stay up late but he always finds you asleep curled up with his pillow.
you guys had previously had the talk and he’s thankful cus tonight your nightie has ridden up, your thighs are parted showing him your bare cunt. he slowly strips off his clothes and trails his hands up your calves and you spread your legs even more.
he kisses up your legs and buries his head between your thighs, licking softly at your slit, smiling when you push yourself back onto his face. he takes his time eating you, suckling your clit into his mouth, tongue lapping against it slowly.
after you cum with a breathy moan he positions himself behind you, sliding his flushed tip through your slick and pushing in. he groans lowly as he sinks into you, your gummy walls sucking him in tight.
he leans down around you, forearms braced onto the mattress, pressing his forehead to your shoulder as he starts to rock into you. he’s panting softly, placing open mouthed kisses on your warm skin. you turn your head in you sleep and he’s immediately kissing down to the newly exposed skin.
“fuck, i love you so much.” he whispers.
his stomach is flexing, sweat dripping down his brow as he works himself up. his arms are shaking and when your greedy pussy cums again he can’t help but stuff you full. he’s still leaning over you, catching his breath before he slowly pulls out.
“gonna clean you up, baby.” be presses a kiss to the back of your neck.
and he’ll go get a warm, damp cloth from the bathroom and clean you up and press a soft kiss to your clit. and another. and another, slowly starting to lick at you again until you moan and then he’s pulling back.
“shhh, ‘m sorry.” he tosses the cloth into the hamper.
he lays next to you and you automatically roll over to him and curl up into his side.
