Things They Do That Make Your Heart Skip A Beat

best friend touya finding out you don't watch porn because you've never found anything you liked.

he asks if he can send you links, show you what's out there from a trusted source. you've always low-key had a thing for him, so you agree, even though a part of you knows there's no coming back to normal friendship after this.

the links start out tame, almost sweet. you've seen porn like it before, the basic shit that looks like a couple made a home movie. it’s not that you find it unappealing; you simply feel nothing watching two strangers fuck like they’re in love.

you send a thumbs-down reaction to the messages.

touya texts back: well shit

a flurry of links blow up your phone and you don’t get the strategy until you find one, buried in the middle, that reads: fucking my best friend so hard he cries

with your heart in your throat, you thumbs-up the message.

touya replies immediately.

omw

wait.

buying those little mini pencils and cutting them down so pocket sized izuku can take 'notes' when you guys watch things together.

pocket sized katsuki nearly falling off your desk or table trying to train his quirk, having trouble with adjusting the power because he's smol.

pocket sized shinsou hanging from things-- i imagine he would have like.. a little swing from things, just swaying lazily while you're busy.

pocket sized kirishima who likes to sit and play with the music on your phone while you work out, declaring he knows the best songs to get you pumped up.

pocket sized uraraka who tugs on your sleeve and you tie a little piece of ribbon around her waist so she can activate her quirk and float around like a mini balloon - aka - fly.

pocket sized toya who insists that he is your personal lighter and has to light candles and stuff for you. and got really upset with himself when he accidentally burned your finger.

pocket sized tomura who gets teary eyed after you spent hours stabbing yourself and cursing trying to sew him itty bitty gloves.

giving pocket sized hawks little pieces of fried chicken because he's going to stare at you until you do. or giving him pieces of puffcorn. 'you could just give me nor--' 'no, it's harder to chew. eat your puffcorn.'

pocket sized himiko that's like having a pet lizard and likes to bite your fingers and not let go. she's ends up a giggling mess when you do that hand shake, wiggle thing.

thinking abt unofficialbf!katsuki

unofficialbf!katsuki who's abrasive and rude and loud until you're near him. he almost instantly sizzles down

unofficialbf!katsuki who proudly declared you as "his" when you were 4 after you accepted his bouquet of dandelions and its kind of just stuck since then

unofficialbf!katsuki who, after that, began proudly holding your hand and marching around with you. at some point, it just became a habit for him to reach for your hand, continuing even as you got older

unofficialbf!katsuki who still apologizes to you the same way as when you two were kids. he holds your hand and looks away as he mutters "'m sorry.." with rosy cheeks. when he really messes up, he'll bury his nose into your neck and hold you close and whisper a genuine apology into your ear. he'll struggle for the right words and get super flustered, but you know hes trying!!

unofficialbf!katsuki who, for as long as izuku could remember, has been a package deal with you

unofficialbf!katsuki who is practically inseparable from you. like youre not hugging in class or anything but theres just this unnecessary proximity with you guys? you're always just unexplainably close for no reason

unofficialbf!katsuki who carries your bag everywhere. he complains that you "can't even carry your own damn bags!!" but would never let you carry them

unofficialbf!katsuki! who beats his friends up for being stupid when they don’t understand something he’s teaching them, but is so gentle when teaching you. he gets real close and talks in this low rumbly voice that’s just SO HOT

unofficialbf!katsuki whos an asshole to everyone but you

unofficialbf!katsuki who, despite being unnaturally nice to you and finds it hard to be/stay mad at you, gets really genuinely angry when you get reckless when fighting. the only times hes ever really yelled at you for real were when you put yourself in danger

unofficialbf!katsuki who doesnt care if mineta and kaminari ogle the other girls but would blow them up if they so much as laid an eye on you

unofficialbf!katsuki who tries to hide the way his eyes soften whenever you talk

unofficialbf!katsuki who, due to your childhood marriage/relationship/idk-its-complicated, is really comfortable with touching you. he would never let any of those other extras touch him, but he never hesitates to grasp your hand when you're scared, grab your waist to pull you in when he just wants you closer, or even pull you into his lap (in private) to cuddle. he has no problem manhandling you and throwing you over his shoulder or even carrying you bride-style when he's reaaally feeling confident. when you sit next to each other, his hands easily find your thigh almost subconsciously to rub his thumb over it soothingly

unofficialbf!katsuki who you've been having tickle fights with since you were little! he would never DARE hit you like he would those other losers, so he tickles you when he thinks you're being annoying. he knows all of your ticklish spots and still uses it against you when he thinks you're being bratty (or when he just wants to hear you laugh, but he'd die before he admits it)

unofficialbf!katsuki who LOVES cuddling with you! (would never admit it) you get all loud and fussy sometimes (no one is allowed to sass him other than you) so he just pulls you close to his chest and drags his fingertips up and down your back in the way he knows you like. he loves how it gets you all quiet and sleepy and clingy in a matter of minutes. he wonders if you notice the way that after just a couple minutes, your speech starts to slur and you bury your face into his chest or neck. (he does. he notices.)

unofficialbf!katsuki who you've been cuddling since you were kids so it just sort of continued as you two got older? you've known him for forever, so it never felt weird or anything. its just oddly natural? mitsuki has photos of you two cuddling from ages like 4-now.

speaking of mitsuki!! she absolutely ADORES you and unofficialbf!katsuki HATES it! he always mutters about how she likes you more than him whenever you come over, which is like everyday, which she always affirms happily. calls you "my sweet y/n-chan," "sweetheart," "dear," "lovely," and of course "my future daughter-in-law." (katsuki always tells her to "SHUT UP, OLD HAG" with bright red cheeks)

unofficialbf!katsuki whose grumpy moods and grumbles are easily halted by you running your hands through his blond spikes, which always turns him into putty in your hands

unofficialbf!katsuki who always has you in his dorm. he has this thing about nobody, not sero or denki or even kirishima being allowed in his bed when they hangout, but he lets you with no problem. in fact, he's the one who drags you into his bed with him.

unofficialbf!katsuki whose classmates have literally placed bets on when his balls will drop and he'll make you his official girlfriend (he cursed them out and blew stuff up when he found out)

can you tell im a sucker for the just friends/unofficial bf trope...

Black Sapphire Cookie 💜

can you do frat boy kirishima or sero?

god yes why not both

⋆.ೃ࿔*:･

the frat bros ✧.*

kirishima x reader x sero ੈ✩‧₊˚

two individual parts third part you get fucked by both of them. lol!!

summary: smut! anal, double penetration, sex, brief oral sex, spanking, squirting. you met kirishima and sero at a frat party that they hosted. meeting them individually, then later on you have a threesome with them.

꩜

intro: you had been at this party for quite a minute, and your boredom was creeping in. only one thing could save you now. a man.

part one: kirishima

thinking about frat boy! kirishima. the man you found in the kitchen. he stood above everyone and his muscles were prominent in his clothes. the alcohol in your system was doing a great job and giving you the motivation to introduce yourself to him. walking over you stumbled before you could fully get to him. embarrassment flooded your system. ‘you okay babe?’ he laughed pulling you onto your feet. ‘i’m fine just…embarrassed.’ you laughed in your hands. he gave you a firm pat on your back with a hand that lingered. looking up and him, you were smitten. he was gorgeous. ‘your gorgeous.’ he said to you. you gasped. his own words seemed to catch him off guard as well. ‘is this your party?’ you asked him with batting lashes. trying to win him over. ‘well yes, it’s me and my friends.’ he answered. you nodded your head in agreement. ‘want to take some shots? here follow me.’ he lead you to the alcohol, a hand on your back at all times. his touch did somthing to you. after pouring the shots, you had put a cut up lime in your mouth. taking it out just to talk to him, ‘take a shot and the lime is right hereee’ you laughed while putting the lime back in your mouth. his eyebrows raised as he looked back at you with a smile. ‘i like the way you think.’ taking the shot he downed it. making a sour face before his eyes locked back into yours. without a word he grabbed the back of your neck and his lips met yours. you parted your mouth for him to get the lime. your felt his tongue venture in your mouth. he groaned, it was noticeable. it was hot. he parted from you before you could notice. opening your eyes you were met with him smiling at you with the lime in his mouth. ‘i hope i see you later tonight. you know what.. i will see you later tonight.’ and with that he walked away. the heat in your stomach uncontrolled.

part two: sero

thinking about frat boy! sero. you had only really heard of him in stories. the guy that somehow was always smoking a joint, always rolling somthing for the pretties girls there. so tell me why tonight, you were sitting with him. it had been a long long time since you saw your friends and your pretty sure they left by now. but that didn’t matter. not when you were sitting with him. it was a long long time since you had been this attracted to someone. and god u weren’t going to walk away without a kiss that’s forsure. the way his eyes trailed and stoped at some areas of your body. you new he felt the same way. you two were the only ones in the room. he whispered a hush ‘cmere baby’, before he pulled you into his lap. he made the first move a soft kiss on your lips, one hand on your ass and the other holding the weed you two had been smoking on. parting you said ‘you kiss everyone like your a gentleman or is it just me?’ you giggled. he swooned, ‘just you baby, but shit… fuck it.’ it wasn’t until he laid his lips on yours a second time that you felt everything he yearned for. his hips jumped under you and the kisses pace fastened. everything felt hot. on cloud 9 even. slobbering and tongue fucking eachother you groaned when he disconnected the two of you. ‘you like that?’ he grabbed your hips, grinding you against his hard length. ‘mmhm!’ you shook your head. ‘stand up, i have an idea babe.’

part three: both

thinking about the two frat boys kirishima and sero, that just loveeee watching eachother fuck you. the two of these guys controlled the party. and now you were in bed with both of them. one you had shared shots with earlier, and the other you had shared weed. you were truly on cloud nine. you laughed when zero showed you him guy friend that also wanted to have a threesome, because really you thought it would be anyone but him. kirishima laughed too, mostly because he was embarrassed. but now, your the one who is embarrassed. sero watched from his spot on the bed as kirishima fucked his fat cock in and out of you with hard pounding. your boobs bouncing from the force. back arched in doggy style, you slurred and moaned. it wasn’t long until sero took over. kirishima moved out of the way for his frat brother to pick you up. your back pressed against his chest. your legs bent all the way to your ribs. your pretty pussy was on full show for both of them. sero positioned himself into as he fucked you full-nelson. you saw kirishima jerk himself off in your peripheral. sero groaned from behind you. ‘isn’t she pretty bro? fucking taking all my cock like a good girl..’ he says as he pumped himself in and out of you. you moaned in response, clenching your walls around his cock. ‘getting fucked like a whore. fuck yes you like that, i can tell baby.’ sero groaned. you watched as kirishima got up from his spot. coming to see the two of you face to face.slowly he bent over and ran his mouth on the outside of your pussy. sero never faltered. fucking into you with faster pace, as his friend laid open mouthed kisses on your cunt. kirishima looked up at you with litted eyes. making sure you noticed him pumping his big fat cock. ‘fuck can we share her sero?’ kiri asked face still planted on your wet cunt. ‘only if she wants too.’ you shook your head yes before they even asked you. now on the bed, kirishima was under you, sero fucking you from behind. both your holes penetrated, kirishima finding a warm spot in your cunt. sero fucked into your ass. both their rhythms were mind boggling and far too much for you. as kirishima grabbed and twisted your nipples, sero spanked your ass. leaving red patches all over your skin. ‘you fucking like this?’ sero said slapping your ass again. you moaned in response. kirishimas eyes never left yours. as he pounded into even when your lost your footing, he held you up. his strong arms taking a grip on your elbows and angling your back farther. ‘feel that sero? how does fucking her ass feel? tell me about it.’ he said with a coy smirk. making your brain melt. ‘feels like she likes when you arch her back like that. fucking slut has a thing for you. everytime she talks she clenches- fuck so hard-‘ sero says laying his palm on your ass again. the pain felt so good. ‘fucka ah! yeah she fucking likes that.’ sero said again through moans. your pussy was pulling them in. ‘gonna cum? y/n are you gonna cum for us?’ kirishima growled as he pounded into you from beneath you. your body racked, lurching forward. you screamed out obscenities and curses. fuck. they weren’t stopping. both the men fucking you through your orgasm, you felt like you were gonna pee. ‘stop! omg stop! ah-! fuck i’m gon-‘ white liquid squirted out of you, soaking both the men in the process. this was the first time kirishimas eyes left yours, too look at the mess they made. sero pulled out almost right after and came on your ass. ‘fuck. we need to do that again.’ you agreeed.

i’m shameless

SECRET LANGUAGE!

synopsis: you and katsuki have a.. special way of communicating.

a/n: i genuinely do the whole 'not say anything js whine and groan until someone gets it' thing and sometimes ppl are confused but i feel like childhood friends + unofficial bf katsuki would just get it

"man, that was so tiring!" kirishima said, collapsing on a common area couch.

"all might sure worked us hard.." ochako added, exhaustion evident in her voice.

the rest of the class all nodded their heads in agreement, too exhausted to talk properly as they all slumped on the couches.

the room fell into a brief silence as everyone took a moment to relax and unwind after the grueling training. after a few minutes, the chatter started up again. they discussed the latest training exercises and something about all might and pro heroes and the possibility of starting a hero agency but honestly, you weren’t really listening. you were exhausted, too worn out to focus or engage properly with the conversation. you sat there silently, sort of just spacing out.

you were snapped out of your trance by a nudge to your shoulder. glancing up, it was katsuki looking down at you, a smidge of concern in his eyes.

"you ok?" he asked in a rare moment of quietness, his voice low and gravelly. "you've been out of it for a while now."

you took a second before you groaned, pushing your head into his shoulder, too tired for words. he made a ghost of a snicker at your antics, smiling down at you gently. (he denies denies denies tho)

"nnnnnghhh. mmmmmm!" you whined.

"i know, i know." he muttered.

"uuuurghhhhh, euuuuhm!"

"you wanna go back to your dorm and take a nap if it's that bad?"

"m. mmmmmmm! ...mmm?"

"hell no! i'm tired, too, and i'm not walkin' all the way to the damn convenience store."

you looked up at him, exhaustion and pleading in your eyes.

he looked back at you.

you kept on looking at him.

he kept on looking at you.

you shoved your head into his neck and nuzzled a bit, silently pleading with him.

finally, he sighed, getting up and rolling his eyes. you squealed in excitement, clapping your hands excitedly. he used one arm to swoop you up and trudged out of the common area with you, muttering about how were "such a damn pain" and "so fuckin' lazy." of course, he would never have it any other way, though. not that he'd ever admit that.

bonus:

unbeknownst to the two of you, as you were in your own little world, but mina had gotten a clip of the confusing but cute interaction, and sent it to the whole 1a groupchat.

kirishima: NO WAY

kaminari: BAKUGO?!?!?!?!?! BEFORE ME?!?!?! 🥲🥲🥲😫😫😫😫😫💔💔💔💔💔

todoroki: I'm confused. What is she saying? What just happened?

...

jirou: idk

momo: it's certainly a mystery

midoriya: kacchan and y/n have always talked like that! it's like a secret language!

sero: i think 'talking' requires back and forth conversation..

mina: WHO CARES? it's cute!

BAKUGOU KATSUKI ✰ THE DRESS CODE

Bakugou was in a bad mood.

It was stupid, really. Absolutely stupid. But he couldn’t help the scowl on his face as he approached your desk.

“Oi,” he snapped, crossing his arms. “What the hell are you wearing?”

He had taken his time this morning, making sure the maroon shirt he picked out was one he actually liked. It wasn’t over the top or anything—just a plain shirt with a white skull on the back, paired with some casual black pants.

But it was the principle of the matter. You were supposed to match. That was the whole damn point.

The UA student council had this dress code specifically to celebrate Valentine’s Day. Maroon for those who’re in a relationship, blue for those in a situationship, green for those in the “friend zone,” black for those who are admirers from afar, and the plain school uniform for those who are more inclined in their studies to even bother with romantic relationships.

Was this your way of subtly denying him as your boyfriend? It wasn’t like you two were in hiding—and it’s not like he doesn’t mention that you two are seeing each other whenever someone pesters him about it.

You looked up, eyes wide and innocent. “Huh? My uniform?”

Bakugou’s brow twitched. “Yeah, I can see that. Why?”

You blinked, clearly not understanding what he was getting to. “Because… it’s Friday?”

“Did you forget what today is?”

You stared blankly at him, confusion written all over your face.

“...Friday?”

“Valentine’s Day!” he barked, causing a few of your classmates to glance over in amusement. He jerked his thumb at his own shirt—a simple red tee with a black skull printed on the back. “Maroon’s for people who are dating. Thought we were gonna match.”

You felt as though your soul just left your body.

“Oh... oh.” Your hands flew to your mouth. “I... I didn’t know! You never told me!”

“Didn’t think I had to. It’s common sense.”

“And you don’t even like Valentine’s Day! So... I thought we weren’t doing the dress code thing...”

That was true. But still! He was adamant on making you look like the one in the wrong here.

“Well, I am,” he pouted. So subtle it could be mistaken for his signature grimace. “And I heard from Ears that you were planning on wearing maroon, you idiot.”

“I told her—I was thinking about it, though.”

Bakugou’s shoulders sagged, the irritation draining a little. “Yeah, well... I went and did it. Thought it’d be obvious we’re together if we matched. You had a shirt with a golden dragon on the back, too, right?”

Your heart fluttered, your gaze finally meeting his. He remembered. The realization hit you like a ton of bricks—Bakugou Katsuki, the loud, brash, and unapologetically stubborn hero-in-training—your boyfriend, wanted to show off your relationship. Publicly. On Valentine’s Day.

A moment in history!

You didn’t know whether to laugh or cry.

Instead, you jumped to your feet. “Wait here!”

Before he could argue, you bolted out of the classroom, leaving Bakugou standing there, baffled. He turned to find his classmates blatantly eavesdropping.

Mina’s eyes were practically sparkling. “Awww, Bakugou, you wanted to match with [Name]?”

Kaminari snickered. “Dude, that’s so cute.”

Kirishima grinned, throwing an arm around Bakugou’s shoulders. “You really have gone soft, man.”

Bakugou’s eye twitched, and he shrugged Kirishima’s arm off roughly. “Shut it, Shitty Hair. I just didn’t wanna look like an idiot wearin’ maroon by myself,” he grumbled. “And Sero’s wearing green—‘nd I don’t see anyone picking on him!”

“Cool it, man,” Sero laughed, shaking his head. “The incident still stings.”

“We salute you, brave soldier,” Kaminari replied.

Mina sighed dramatically, resting her chin on her hands. “Young love...”

His cheeks turned crimson. “Mind your own damn business!”

Before his embarrassment could escalate, you came running back, slightly out of breath, with something red clutched in your hands. You unfolded it and slipped it on—a maroon cardigan. It hugged your frame just right, with allowance to spare, the color bringing out the warm shimmer in your eyes.

You looked at him, your fingers fiddling with the buttons. “I had this in my locker. Does this work?”

Bakugou stared at you, his irritation disappearing like a factory reset process. You looked... cute. Really cute. But he wasn’t about to say that out loud. He cleared his throat, shoving his hands into his pockets.

“Yeah... s’fine, I guess.”

Your face brightened, a smile breaking across your lips. “Really?”

He looked away, his voice gruff, though there was no heat in his reply. “Whatever.”

Their moment was interrupted by Mina’s dramatic squeal. “And they say romance is dead!”

Denki gave a thumbs up. “Didn’t think Bakugou could be such a romantic.”

Kirishima laughed. “Man, who knew you’d be such a softie?”

Bakugou’s eye twitched, and he spun around, his hands sparking. “One more word and I’ll kill all of you!”

His classmates laughed, not the least bit intimidated. They could see right through him—Bakugou Katsuki was completely, undeniably, head-over-heels for you.

Turning back to you, his voice softened, his anger dissipating. “C’mon, let’s go. Cafeteria had those stupid snacks you wanted.”

Your smile never wavered as you followed slightly behind him.

“Happy Valentine’s Day, Katsuki.”

“Yeah, yeah... Happy Valentine’s Day.”

Bakugou hopes the next Valentine’s Day to come is when he can properly match with you. He won’t let you forget this time around.

SEUMYO © 2025. PLEASE DO NOT REPOST, PLAGIARIZE, MODIFY OR TRANSLATE.

you enter your room after a long day. there's nothing more you want than to just flop onto your bed and take a nice, long nap. however, as you throw your bag to the floor and are just about to dive on to the covers, you notice a pillowcase that is bright pink.

narrowing your eyes, you apprehensively poke the pillow. nothing. you slowly sit down near the end of the bed, staring at the obscure sight, pondering what that is all about.

until it occurs to you, that you've not seen your boyfriend for the last couple hours. you exhale out of your nose sharply and say, "saiki?"

"no. your pillow." the telepathic voice replies directly into your head.

you smirk, "my pillow usually doesn't talk back."

"oh." his voice echoes through your mind and causes you to chuckle, "yes. it's saiki."

"why have you morphed into a pillow?"

"as a prank." he states simply, though his answer only confuses you more.

"how is that a prank? i was about to lay down on you and crush you with my head. where's the funny?"

"i planned to release my feathers while you sleep, which would make you sneeze."

your face contorts into a digusted expression, and you hiss, "release your feather? all over my room? gross!"

"don't make it sound like an innuendo." the pillow said.

"too late. you already made it sound like one." you shrug, shuffling closer towards him. "are you going to transform back now or?"

"yes. please give me a mom—"

he is interupted as you swiftly pick him up by the corner and hurl him against the wall. his pillow form makes impact with the wall, then he transforms back into a human and dramatically slides down, until he is laying dejected on the floor.

you frown, almost feeling bad for your implusive decision. "sorry. dark reunion made me do it."
