ᝰ.ᐟ꩜ AUTHOR’S NOTE :: e/c = eye color ★ i/n = initial name ★ this might be the worst story i’ve ever wrote like i had insane writer’s block and i just wanted this to end, i started writing this december 23rd and i just finished today (january 30th)
the last bell of the day had just rung in your ears, waking you up from your groggy slumber. you lifted your head off the desk to see mina standing over you. she laughed as she snatched the paper that was stuck on your cheek and turned in the work for you.
“why’s the princess so sleepy today?” another voice arose from behind you. it was no other than kaminari to say something as corny as that.
“first, don’t call me princess and second, i was up all night doing the project that mr. aizawa paired us together for, which you didn’t do a single piece of.” you grabbed your backpack and threw it over your shoulder.
“wait we had a project?” he stood up and asked.
you and mina both rolled your eyes and left the classroom.
“anyways, you have any plans this weekend?” mina asked while she twirled a strand of her pink fro with her finger.
“uhh noo,” you thought, “i mean a new episode of abott elementary just came out, so i’ll be watching that.”
“oh my gosh, i love abott! we should watch it together,” mina exclaimed as you nodded in agreement. “okay, well, i have to go clean my house before you come over, so i’ll see you soon, girl,” she waved.
“okay byee,” you waved back, then you and mina parted ways. after that, you went to get the rest of your stuff out of your locker.
while you were walking, you noticed your friend kirishima from a distance waiting by your locker. nobody knew—except mina of course, that he was your biggest crush. he’s handsome, strong, a gentleman—just everything you could want in a man.
“hey y/n.” he smiled at you with his regular wide grin.
“hey ‘ri.” you replied in the same tone.
“how was your day today?” he asked while messing around with the spikes of his hair.
you began to blush at such a simple question. “it was good, how about you?”
“good now that i can talk to you,” he smirked.
you both giggled as kirishima started to rub the back of his head. “soo,” he started, “wanna come to my pool party this afternoon?”
you finished grabbing your stuff out of the locker and closed it shut. “ooo yeah, sure! can i bring mina?” you smiled.
“i mean, yeah, i guess,” he shoved his hands in his pockets. he looked taken aback at you inviting mina, but it’s a party, right? so the more, the merrier.
“so your house?” you asked, he nodded. “6:30, don’t be late,” he spoke softly.
“i won’t!” you smiled at him. kirishima waved and walked off with bakugou while you were doing backflips inside your head.
you’ve never been to a pool party before, let alone have your crush invite you to a pool party. and it was perfect since mina was going to be there for backup. you rushed to the bus and headed home to pack. once you finished, you went to mina’s house like you had planned to. when you got there, you explained to her that kirishima invited the two of you to the pool party.
“oh my gosh! actually?” mina squealed. “that’s amazing. come on, we have to find you a cute bathing suit in my closet,” she dragged you by your arm and sat you on the bed.
mina dug into her bottom drawer that was filled with bathing suits. she picked out one for herself and one for you too. she laid both options on her bed for you to pick.
“these are the cutest two pieces i could find,” she smiled.
the first one was a light blue crochet bathing suit that had blue and yellow flowers on them. the second one was a teal swimsuit with orange and yellow floral designs.
“that one!” you pointed at the light blue swimsuit.
she grabbed the swimsuit and tossed it in your hands. “quickly go try it on!” she flicked her hands repeatedly.
with that, you quickly left to go inside her bathroom to try on the bathing suit. it was so cute on you, you could literally die. you walked out of the bathroom and gave mina a little spin before posing.
“ohh m’ geeee it’s literally to die for!” she smiled. she went into her pants drawer and pulled out some light-washed denim shorts and tossed them at you. “wear those with them.”
your face caught the jeans and slipped on the floor. “…thanks.” you giggled. “for my hair… i was thinking i could just do a high bun, wouldn’t that be cute?” you sat down at mina’s vanity, trying to picture your hairstyle.
“yeah totally! i’m gonna shower real quick but i’ll see your hair when i’m done.” mina grabbed her bathing suit and towel and walked towards the bathroom.
“kk!” you sang happily. you looked at yourself intently in the mirror, trying to see how you could pull off this look. after some time, you finally managed to put your hair into the high bun. after you finished, you hopped onto the jean shorts and slipped some white sandals on.
mina walked out of the bathroom with her bathing suit on and short white jean shorts. “girlll, we finna be the cutest people at the party.” she jumped up and down, unable to control her excitement.
“stop!! don’t get me excited!!” you jumped with mina too, but then stopped. “but what am i gonna do when kirishima talks to me? i get so nervous around him, it’s unbearable to watch.”
“don’t worry, girl, you’ll be fine!” she pulled out her phone from her back pocket and checked the time. “oh shit, girl, we gotta start walking if we wanna make it in time to the party.” she grabbed her pink towel and threw it over her shoulder and tossed you a towel.
you caught the towel and started walking out with mina. you were greeted by the warm, cooling breeze that wrapped around your skin; the sun was enhancing all your facial features by its illuminating glisten. your e/c eyes sparkled, and your lips looked more plump and radiant than ever. the air was thick but soothing as you and mina walked down to kirishima’s house.
mina took out some aquaphor and lip oil and handed it to you. “here, put the aquaphor on your eyelashes and some on your lips. then coat the lip oil on top of it.”
you grabbed the items and did exactly what she told you to, making you look even prettier. “is it giving face?” you pucker a kissy face. “girl, you already know it is,” mina giggled.
once you got to kirishima’s house, you rang the enchantingly rich doorbell. as the door opened, you would’ve expected to see kirishima since it’s his house your at, but you only saw the flirtatious blonde at the door with his friend sero (who's ten times worse than him).
“woahh babes squad,” they shouted while grinning at both of you, which made you and mina burst into laughter.
“move out of the way.” mina playfully pushed kaminari's face out of the way, making him fall back as you two walked in. kaminari’s annoyed eyes followed mina, yet his rude gaze subsided as he heard you giggle. you outstretched your hand and helped pick him up.
“you okay?” you fixed his hair before smiling.
“shiid, i am now,” his eyebrows raised.
kirishima walked to the main room to see you fixing kaminari’s hair, and for some reason, he didn’t like that. why’d you never fix kirishima’s hair when it’s messed up? he walked up and cleared his throat.
“hey y/n!” kirishima smiled.
“oh hii ‘ri!” you walked up to kirishima and gave him a hug.
he blushed as his hands were about to wrap around your waist, but he chose your upper back instead, to be a gentleman. he grabbed both of your shoulders and gently pulled you back from the hug to examine you and your outfit.
“you look beautiful in that swimsuit,” he complimented. you always looked gorgeous in his eyes, even at times when you didn’t dress yourself up.
“thank you kirishima,” you blushed. “you look good as well, the red swimming trunks suit your hair.” you complimented him while you fixed his droopy spiked hair from what you assumed the water had caused.
he watched as your eyes looked up at his hair while you fixed it. he smiled for a second, but then asked himself. was that just a friendly gesture or were you flirting?
“soo,” you rocked yourself back and forth on your tip-toes, “lead me to the pool?”
“oh shit, yeah my bad,” he chuckled, and he led you to the backyard.
his pool was very luxurious. he had a diving board with a pool that went from five feet to seven. the pavement was a very detailed white stone and had another spot for a hot tub. there were many chairs set up to tan. you scouted the place out and already saw mina flirting with a guy. the entire class 1-A was there, even a couple of class 1-B and C.
you walked over to a bench to take your clothes and sandals off and place your towel down. you walked over to the deep-ish side of the pool and dipped your foot in the water. while you tested the water, you felt a pair of big hands push you into the pool unexpectedly, messing up your bun. you rose your head up from being underwater to reveal kaminari and sero laughing at you at the edge of the pool.
“awww my hair!” you whined. you slammed your hands into the water, which caused more water to splash onto you.
sero and kaminari continued to laugh, “don’t come to a pool party if you’re afraid of getting wet, princess.” kaminari spoke before cannonballing right next to you, along with sero.
“stop calling me princess or i swear i’ll drown you in this pool,” you slapped his muscular arm.
there were a lot of people in the pool by now, but all kirishima could notice was that you were with kaminari instead of him, the person who invited you! he tried to think of some pool games to play that would bring you two together.
“let’s play volleyball!” kirishima suggested, while everyone else agreed.
he took out a long net that went across the pool and got a big beach ball. bakugou was one of the goalkeepers and shoto was the other. there were six people in each team, and you were obviously going to be on kirishima’s team, and kaminari was obviously gonna be on your team as well.
now, kaminari was a dumb ass, but he wasn’t any dummy. he knew that kirishima had a crush on you, so his only intention tonight was to troll you and flirt with you. don’t get him wrong, you were very attractive—and if it wasn’t for kirishima liking you, oh, kaminari would’ve been had you.
“0 serving 0.” you yelled as you overhand served the ball to the other side of the net.
˗ˏˋ ★ ˎˊ˗
“15 serving 20.” ida exhaled annoyingly. he hated being on the loser side. he served the ball with a jump serve that launched right onto kaminari’s face and the ball bounced all the way out of the pool.
“holy shit!” bakugou chuckled as he gave a point to ida’s team. everyone else burst out laughing.
you swam to kaminari, “you okay? that looked like it hurt.”
“i’m okay princess, i’ve been hit with worse, i promise.” you both laughed.
kirishima noticed you quickly, how you were always quick to help someone. he'd usually find it endearing, except when it came to kaminari being the person you were helping. “were you trying to get into his head or were you truly being nice?”
“okay… next game. how about a chicken fight?” kirishima said.
“wanna be my partner?” kaminari turned to you quickly while smirking at kirishima. you didn’t notice though, so you just shrugged. “yeah, sure.”
uraraka then ran over to the pool, “ooo, i wanna play! please please, who doesn’t have a partner?”
“kirishima doesn’t,” shoto pointed over at him, “oh yeah, uraraka, we can be partners.”
once everyone got situated, you got onto kaminari’s back. he wrapped his hands around your legs and pretended to let you fall, making you squeal.
“stop!” you giggled, “i don’t wanna fall.”
“you won’t fall, i promise,” he spoke softly, your giggles sending both kirishima and kaminari on edge.
he watched you intently as you were basically flirting with kaminari in his eyes at this point. he had then put uraraka on his back and wrapped his arms around her thighs. you knew that’s what he had to do in order to stop her from falling, but you couldn’t help but feel…jealous? you didn’t know, you just hoped uraraka didn’t find kirishima’s muscular arms attractive like you did.
the chicken fight had begun and everyone started going after each other. it was pretty easy to knock everyone down until it led to uraraka & kirishima and you & kaminari. kaminari foolishly sprinted towards them when you weren’t ready, which made you fall backwards. you fell under the water while everyone was laughing, until you didn’t get back up from under the water.
the laughter began to falter as kirishima took uraraka off his back and swam towards you quickly. he grabbed you by what he assumed was your waist, and you lifted your head up and burst out laughing.
“you think i can’t swim?” you laughed uncontrollably.
his worried face slowly turned into a nervous chuckle. “that’s not funny y/n.” he gruffed, his grip still on your waist.
“don’t be so worried.” your contagious laugh started to make him chuckle a little.
he couldn’t help but notice how beautiful you looked, just absolutely stunning. the water lubed up your eyelashes, which made them match perfectly with your beautiful eyes. he found it even more adorable the way he noticed you continued to kick your feet under the water to stop yourself from sinking.
“you hungry?” kirishima asked, moving you both to the edge of the pool.
you hummed for a moment, “yeah, a little.”
“there’s some food on the grill, i can get you a burger,” he offered.
“oo okay, thank you,” you smiled.
as you were about to get yourself out of the pool, kirishima picked you up by the waist and placed you on the edge of the pool. he then used his upper body strength to lift himself out of the pool as well. you kicked your feet in the water, waiting for him to return. you saw mina in the distance giving you the thumbs up. you laughed and gave her the thumbs up back.
the wind started to pick up a little, so you decided to go into the hot tub while you waited. by now everyone was drying off and heading inside the house. it was only a couple of people; some people from class 1-C and kirishima.
when he came back empty-handed, you looked at him confused. “sorry i had to put more food on for you. but can i uh, come sit with you?” he asked hesitantly.
“yeah, of course,” you smiled while scooting over.
you two were now sitting in the hot tub together. you two started talking about random things, but the whole time it looked as if he was contemplating something to say.
“something on your mind?” you asked sweetly once the conversation became quiet.
“oh, i was just thinking about something,” he smiled at you.
“say itt,” you nudged his arm playfully.
he cleared his throat before saying, “do you, uh, like…kaminari?”
you face scrunched up at his question. “ew! of course not! he’s such a weird little pervert.”
“oh, good,” he sighed. “why though?” you followed with another question.
“just seemed like you did.” his eyes didn’t meet yours like it usually did.
“are you jellyyyy?” you looked at him while smirking.
“why would i be jealous of him? just because he’s been flirting with you, being around you, and calling you princess the entire time, you think i’m jealous?” you nodded.
“i mean yeah, i would be jealous if you did all that stuff with someone else,” you mumbled.
after you spoke, it was silent. all that was heard was the water moving around and the muffled sound of everyone inside the house. the blinds were closed from inside the house and the last couple of people that were outside had just gone inside.
the awkward silence was slowly getting to kirishima. all he wanted was to just confess to you already, but he couldn’t just blatantly blurt out that he likes you. or maybe he should make a move on you? he didn’t know. he also didn’t know he was subconsciously checking you out, making his bulge grow inside his swimming shorts.
he thinks he was finally building up the courage to say something, “hey, y/n—”
“supp i/n dawgg.” mina slid by the hot tub and wrapped her arms around you drunkenly.
“bro, where did you get alcohol from? and get off of me.” you chuckled a little while trying to untangle her hands off you.
“oh— shit am i interrupting? were you about to tell kirishima how you lovvvvveeeee him?” she slurred, your eyes shot open and your mouth agape slightly.
“brb bout to get another drinkk,” she sang, as she skipped towards the door.
now the tension was even thicker now that mina had just confessed your feelings to kirishima herself. he looked back over at you, just as surprised as you were.
“there's no fucking way she just said that...” you dragged your hands over your face embarrassingly. now you can understand why kirishima didn’t want mina there.
“soo you like me?” kirishima grinned, while all you could do was slightly nod. “well, that makes two of us.”
“you like me?” you exclaimed, he nodded. “like, like-like?” he nodded again. “like, dating-like?” he nodded once more.
“oh my gosh, why did you go all this time without saying anything?”
“the same reason you didn’t,” he shrugged, “but we can make up for the time wasted.”
you felt your cheeks starting to burn up. “what’s that supposed to mean?” you giggled.
his hands reached for your waist as he gently reeled you closer to him. “i can show you, better than i can tell you—if that’s okay with you.”
ugh such a gentleman, you nodded excitedly while breaking into a smile. he smirked as well as he pressed his lips against yours.
the kiss was gentle and slow. your hands glided up to his cheek while he guided you onto his lap. his hands slowly caressed your outer thighs and repeatedly led up to the small of your back. his lips were so soft, they moved perfectly against yours, molding together like they were made for each other.
his slipped out his tongue into your mouth while your arms snaked to the back of his neck. your heart was pounding while also leaving you the thought of where all of this was going to head for you both.
finally, you two broke from the kiss with a kid-ish smile fuming through both of your faces.
“awww, so adorable,” kaminari stated as he flipped the hamburgers kirishima neglected.
“burgers are ready!” he turned off the grill and took the cooked patties inside the house.
you and kirishima looked back at each other before laughing and getting out of the hot tub. he handed you your towel, and you wrapped it around both of you and walked inside the house where everyone else was.
˗ˏˋ ★ ˎˊ˗
once it hit 10:00pm, everyone started to leave. sero drove mina home while you stayed behind and helped kirishima clean up from the party.
“you hosted a great pool party by the way,” you complimented while putting on your shorts from earlier.
“thanks. i’m glad you came,” he smiled as he swept up the floor.
“me too,” you agreed.
“you going anywhere after this?” he asked.
“yeah, i have to get my stuff from mina’s house, then i’ll be going home.” you finished throwing away all the party cups and plates.
“i can take you home if you want me to,” he offered.
“you sure? we would have to go to mina’s house since i was dropped off there.”
kirishima shook his head. “‘s not a problem, i’ma go put on something else, then we can go.” he grabbed his damped towel and headed upstairs.
while you waited, you gathered all of your belongings and finished cleaning up the rest of the mess until the house was spotless. kirishima came back downstairs swinging his keys on his finger while wearing a black t-shirt that clinged onto his abs and baggy gray sweatpants that hung low on his boxers that were titled “RED RIOT” all around the black band.
“you really didn’t have to help me clean up,” he made aware, opening the door for you as you stepped outside. he closed the door behind you and locked it up.
“i know, but it was easier on your half, and i really didn’t want to deal with walking mina’s drunk ass home.” you both laughed.
the night was dark, the air was slightly thick with a warm breeze. kirishima unlocked the door and opened the passenger door for you. you thanked him as he closed the door and did a little jog around to the driver's seat.
he buckled his seat belt and looked over at you. "you don't have a shirt?" he asked like a concerned parent.
you looked down and realized you had forgotten to bring a shirt to wear. "oh—how did i forget that?" you chuckle shyly.
"i think i have a jacket lying in the backseat," he reached behind his seat and grabbed a black jacket of his that smelled just like him.
"here you go," he passed you the jacket. you blushed while grabbing it from him. "thanks" he hummed in acknowledgment.
he pulls out of the driveway and starts driving to mina's house, you ramble about your plans for the rest of your weekend. once you guys made it to mina’s house, he waited in the car while you went inside to get the rest of your stuff. you exited the house, put your school bag in the backseat of the car, and got back into the car.
“thank you for driving me home, ‘ri.” you smiled.
“anything for you.” he chuckled at his nickname.
it was a quick drive, and before you knew it you were already in your parents’ driveway. kirishima turned the car off, yet you both stayed in the car for a second.
“you know, i still can’t believe we both liked each other, and we didn’t say anything.” you looked over at him.
he turned his gaze over to you and he chuckled. “yeah, i know, but i think i made up for it pretty well,” he smirked.
“mmmmm, i don’t know,” you started, “maybe you should make up for it again,” you smirked.
“i mean, if you say so,” he laid his elbow on the armrest and leaned into you, placing his hand on your cheek.
you held onto his wrist as you deepened the kiss. he slid his tongue in your mouth before his hand fell down to the back of your neck. his lips slowly moved from your jaw all the way to your neck where he planted many soft kisses.
you tried to hide the moan that was stuck between your throat, yet it silently slipped out as he sucked on the sensitive part of your neck. once he found your soft spot, he continued to suck and kiss that spot to leave more moans spilling from your mouth.
at one point, it started to tickle, which made you giggle. “okay, okay,” you tried to push his head from your neck gently, “if i get a hickey, my mom’s gonna kill me.” you laughed.
“my bad,” he rubbed the back of his neck. the both of you then got out of the car, and he walked you to the front of your door.
“did you want your jacket back?” you were unzipping the jacket before he shook his head.
“no, you can keep it,” he smiled while zipping it back up for you, “it looks cute on you anyways,”
“yay, okay!” you cheered. you two then shared your goodbyes before ending off with a sweet settled kiss.
“see you tomorrow, ‘ri.” you gave him a hug.
“see you, love.”
