slapping their butt (aoba johsai)

a/n - bye this is so funny lmfao and UNEDITED

oikawa toru | matsukawa issei | hanamaki takahiro | iwaizumi hajime | kunimi akira | kyotani kentaro

fluff + established relationship + pre-timeskip x gn! reader

warnings - you’re slapping butts, you’re getting your butt slapped, idk if i was on something or not when i wrote this but if your not comfy with that then don’t read it obvi!

————————

# 1 oikawa toru

- is so OFFENDED! when he turns to face you and sees you trying to hide your laughter, he tries to give you a blank stare and feign intimidating vibes. although, your infectious laughter causes him to laugh too. as your running away to try and escape, he grabs your arm to pull you closer to him, “get over here, love, you’re not getting away that easily” and then really ‘hits it till he breaks’. probably starts laughing at you when he sees you rubbing your butt to soothe your pain.

#2 matsukawa issei

- he freaking laughs. like, you hit him pretty hard too, and you were so confused when you heard his laughter. yea, he leaned forward a little, but for the most part, he just shakes it off as nothing and continues on with what he’s been doing. weeks later, when you're talking to a good friend of yours, he decides to come up behind you and slap your butt. hard. you let out a yelp of surprise while mattsun and your friend bursted out laughing.

#3 hanamaki takahiro

- you don’t even get to slap his butt, HE KNEW BEFORE YOU HAD THE CHANCE- curiosity plagued your th0ughts when your hand slapped nothing but thin air, as you looked up to meet his stupid grin. “this is definitely interesting, right?” he asked, before grabbing your suspended hand and dragging you along his way. when you let your guard down and eased up after a short time walking, he playfully slapped your butt when you least expected it.

#4 iwaizumi hajime

- after he didn’t see you passing by him in the hall, you decided to slap his butt and run away. immediately blaming oikawa, he yelled profanities at him before makki and mattsun ratted you out. queue him looking around his surroundings, spotting you, saying “there you are,” rolling up his sleeves, and fast-walking towards you. by the end of the passing period, the two of you ended up at the guidance counselor’s office, promising to not slap each other’s butts on school grounds- while you iced your butt.

#13 kunimi akira

- poor boy was just laying on his tummy, chilling in bed and scrolling thru his phone, when you came up behind him to smack his butt before laying down next to him. while rubbing his butt, he looked over and asked “the fck did you do that for?” he didn’t expect for you to say that his butt was nice and squishy- giving you a soft smile, and calling you a “weirdo” under his breath, he sets his phone down and pulls you closer, taking an unexpected nap together.

#16 kyotani kentaro

- you’ve lost a bet with mattsun and makki, and as a punishment, you had to go slap your boyfriend’s butt. with him having a soft spot for you, you thought that you could get away with that unharmed. although, kyoken did not hesitate to throw a volleyball at you (not that hard tho- but it was also a head shot). “why are you like this, babe?” he asks, before letting you get a running head start because swiggity swooty, he’s coming for that booty.

ohhhhkayyyy what was i on this was funny but what was i on

reblogs help others see my work + feedback is greatly appreciated!

[heich0e]

iwa is stiff and awkward the entire time.

HAHAHA YES.

imagine him being the one getting pulled into hostess clubs the most (Oikawa thinks it’ll him, but no, sorry bb). he’d try and refuse respectfully while trying to keep his composure, but Makki and Mattsun are just there pushing him. ( ˘͈ ᵕ ˘͈♡)

(obvi can’t go in cause they’re still underaged but that won’t stop girls from gravitating towards our lil spikey guy)

— 🦊 Anon

IWA WAS 100% THE HOST TARGET and he was SOOOOOOO BLUSHY AND FLUSTERED but he'd always be so so SO polite to them which only made them tease him more oh my GODDDD

your brain is so big and powerful i am in awe!!

[aiiwa]

my favourite headcanon about nojime is that iwa and i are the first serious relationship in his friend group. we are literally mother and father of friends (he is the mum obvi). but it means sometimes we’ll wake up in the middle of the night to find either oikawa, mattsun or makki trying to slide in between us on our bed after a break up or failed date 😭😹😹😹😹

[undermattsun-archive]

i act like i’m ok but rlly i need a middle blocker to give me head

[kaijime]

i’m thinking about morning sex with mattsun 🥺🥺 soft touches and hard kisses (and the horsecock obvi) 😩

morning sex with mattsun

cw. f!reader, morning sex, consented somnophilia, oral [giving/receiving], face fucking, praise, face sitting, [one] thigh slapping, daddy kink

wc. 800+

a/n. morning sex w mr horsecock <33

the little ray of sunshine blinds you, making you shudder yourself to a wake and cover your face with your hand. it still feels too early to wake up, and yet, the few steps it took to close the curtains bring you new energy. you convince yourself to lay back down on the bed, try and sleep a few more hours, just like he does.

yet, your curious eyes get the best of you, putting the covers under your face and looking down to see him, briefs hanging low on his sleeping body. you can’t help thinking about him, now that you’ve got the smallest idea of him, he’s infested your mind.

soon, you’re filled with thoughts of his hands on your body, his heavy cock inside your little hole. it always took so much prep to get you ready for him, and even then your thighs would shake and you would whine about how it was too much, cumming around him without the need for more friction. but he wasn’t doing any of that right now. he simply slept on his side, a light snoring sound accompanied the occasional rise of his chest.

“mattsun?” you called out, trying to find any signs of him faking his slumber. he didn’t do anything, still the same unconscious frown on his face as he sighed in his sleep. your shift to sit on his lap, turning him on his back and leaning your hands on his chest, still no signs. perfect.

you slowly crawl down his body, putting the sheets over you when you finally lay on your stomach with his crotch close to your face. your feet are kicking in the air, knowing he’d be so delighted with his curries once he woke up.

you take off his briefs, just enough to see his soft cock and start licking at the tip. it doesn’t take long for him to be hard, his sighs becoming heavier and longer than before, signaling he was slowly waking up.

it’s hard to take him in your mouth, having to leave out half of his dick because it didn’t fit, and stroking it with your hands. you suddenly hear a faint “fuck” and a hand pushing against the back of your covered head, but you look up to find him with his eyes closed, seemingly still asleep. you start bobbing your head up and down, hoping it would finally drive him awake so he could see the pretty sight before him.

he would always spend the rest of his day in a good mood whenever you woke him up like this, so it was no surprise to see the smirk on his face when he finally opened his eyes and lifted the covers to see you, hollowed out cheeks around his cock and tears swelling at the corners of your eyes.

“good morning, princess” his hand doesn’t leave your head, slightly pushing you to take him further down your throat, careless to the gagging sounds you made. “you look so pretty, all for me?”

“all for you, daddy” you whine, gasping for air when he finally lets you go. your hands keep the same relentless pace around his cock, slightly teasing the tip with your thumb until he bucked your hips under your touch.

“f-fuck-! don’t tease me” he slams your head down, hitting the back of throat in one smooth push, it’s almost too much for you. “breathe” he orders, calming voice telling you exactly what you had to do, and who were you to deny him?

“mmh!” you moan around him, sending pleasurable vibrations up his cock, making him shiver and shake his thighs as he came in your mouth. you did your best to swallow it all, but he came so much, a small bit slipped past the corners of your lips and down your chin.

“good girl” he praises, gathering the slick that dripped down your chin and pushing it into your mouth. you accepted his fingers with glee, smiling at him and licking away at his thumb.

“‘m your good girl?” you asked, and he gave you a reassuring hum, caressing the side of your face in affection.

“mm, so good, you deserve a reward” your eyes lit up at the words, it wasn’t often he would reward you.

“really?” you question when he sits up, gripping your thighs and lifting you with ease until your dripping cunt was hovering over his mouth.

“yeah” he says, hot breath fanning over your delicate heat, just enough to make you squirm. “want you to sit on my face, you’d like that, right?”

“please” is the only thing you can mutter before he forces your hips down on his mouth, licking and nipping at your inner thighs while you did your best to hold onto the headboard. “mattsun!”

he slaps your thigh and pulls you away. “that’s not my name” he says, panting for air, but still desperate to be back between your thighs.

“d-daddy!” his tongue circles around your clit, teasing the little nub and licking between your folds, gathering all your juices with his tongue. he looks up to you, pleased to see you’ve thrown your head back in ecstasy, glad to feel your hips bucking wildly against his face. just the sight he likes to see when he wakes up.

i feel like oikawa would love the ego boost that comes with getting a shy girl to open up to him n be vulnerable with him. whether that means seeing her when she’s emotional/passionate n is excitedly rambling or slapping his chest n calling him an idiot for something stupid he said or if it’s him looking into her dazed eyes with two fingers pressing her tongue down and his other hand toying with her clit through her underwear n talking down to her. like something about the fact that in front of all his friends ur so reserved and makki and mattsun are appalled at how someone so unlike oikawa’s showy n unabashed exterior is such a good match for him and obvi there’s more to it but oikawa can’t deny how powerful he feels when he gets u all strung out on his touch alone.

stop this physically sent me into orbit. i can't even think :(((((

[shunsuiken]

hi hello i have a fluffy req ft. oikawa 😳😳 spare headcanons pls where he and reader are a new couple 😴🤲🏻

omg yesyes of course!! thank u for requesting<33

oikawa and his s/o are a new couple.

OKAY SO you and kawa are dating and y’all are about three weeks in

by this time yall are holding hands in public and going out to convenience stores after school when hes free

or yknow how kawa stays at school to practise his serves cus hes such a hardworking bby that sometimes forgets to eat dinner ??

yeah so when you find out your mans is still dripping in sweat at 7pm you obviously march your way to the convenience store to buy him some food and water

you also like to buy extras just in case iwaizumi is still hanging around cus you also feel bad for the dude

oikawa also began clinging onto you during breaks and lunches, its his way of showing everyone that you’re his

like he does this so often that you don’t even bother to check who it is cus you already know its oikawa

“yeah dude i totally prefer-” then you’ll feel oikawa’s arms wrap around your shoulders, naturally catching his hand to hold

your friends love the dynamic you two have LMAO

sometimes he just cuddles his face into your neck, you still need some time to get used to this (depending on how comfy you are with physical touch)

if you’re still not used to it, it gets you flustered because you can feel his warm exhales on your neck and its just 🥴

if you’re used to it already, you’ll run your hands through his hair, hearing him sigh (dude its the cutest shit ever tf)

its almost like hes a cat

wait no-

n e ways

pros of dating oikawa: only you get to touch his hair and its so fucking soft

but obvi this rule doesn’t apply to iwa, makki and mattsun like those dudes will put him in a headlock and mess his hair up anytime anywhere

both of you also began to match up your outfits during dates as well

oikawa brought this up, like he was scrolling through a socmed platform (ig, twitter, whatever ya like) and hes looking through couplewear and his eyes literally sparkle

he definitely shares these clothing accounts to you through dm and goes “👀” then you’ll scroll through the account to see what they offer

“y/n-chan, we’re wearing these tomorrow” and with the message is a photo of the bright blue sweater that could pass as an official school uniform

and you’re like “what”

and hes like “i better see you wear it tomorrow 👀”

and the next day, you come to school wearing that bright blue sweater and oikawa is ecstatic when you arrive at school

he immediately calls iwaizumi to help him take photos of you and sometimes you pretend to not want to take photos just so you can see him pout

hes cute okay 🤕

iwaizumi is always the victim when it comes to taking photos of you and oikawa like hes always there to help out 💀💀

“HURRY UP SHITTYKAWA NO ONE CARES ABOUT YOUR HAIR”

“SORRY THAT I CARE ABOUT MY HAIR, YOURS LOOKS LIKE A CACTUS, IWA-CHAN”

you’re kinda just in the middle of these idiots like 🧍🧍

you also have to refrain iwa from hurling your mans into space because with those guns of his..... he literally could

home dates also happen when both of you use up all your weekly allownaces 💀

smh oikawa prolly spent it all on his hair products and skincare

nothing sexc yet because yall are still new 😚

[lacharcutiere]
