KiriKami! just all around positive cuteness

Melissa Schrag

Kiri and Baku if they were in the Avatar universe. Kiri as an earth bender and Baku as a fire bender.

Jarrod

Or if we're going nsfw, KiriBakuKami or KiriBakuDeku fucking with puppy!Kirishima and kitty!Kami (or kitty!Deku)

Jay

KiriBakuKami arcade date!!

KiriJirou-Sirens that hunt together and sink ships KiriTodo- A prince enamoured with a Fey leading him into the forest FatKiri - Comfort and love, platonic or romantic, cuddles and food dates

Rashel Izro

Shinkiri! Maybe training together and Shinsou is flirting more to see Kirishima blush than to get a response out of him?

KiriDeku kingdom AU? Deku as a temporary hire at the palace and Kiri as a long-time servant showing him the ropes? You could totally make one of them royalty if you want. Or hunters/knights. I just love kingdom AUs way too much. KiriKami is also hella good but I thought Deku fit the kingdom AU suggestion better

KiriSero? KiriShouji. Uhhh. KiriChako. KiriTsu

OMG! Love Kirishima. As a Rare Pair Captain myself, I have LOTS of ideas for him. BakuKiri : Go camping, (Re: Brokeback Mountain. WITHOUT the angst. We 100% support Happily Ever Afters in this house!) KiriDeku: It starts off as two friends both pinning after the same ABG. Angry Blond Gremlin. But after time, they find they have a lot in common and end up falling in love with each other as well. (Though if a certain ABG ends up joining them in the end, well, that's just a bonus!) TodoKiri: Kirishima discovers that Todoroki is touch starved and it wouldn't be manly to leave a man in pain. Small touches turn into long hugs and nights spent cuddling under a blanket watching movies. ... Which could end up as so much more with time. 😉 KiriKami: Everyone knows that Kaminari goes dense when he over uses his quirk, but only Kirishima seems to notice how much it mentally hurts when Denki is laughed at for it. Sure Kaminari doesn't say anything, but Kirishima sees the frown when Denki thinks no one is looking. A good friend isn't about to let his buddy be down in the dumps, so of course Kirishima does all that he can to pick his friend up. KiriToko: He can't help it. Dark Shadow is just so cool, and the way Tokoyami handles his quirk? Familiar? He's not sure what Dark Shadow is, but just how both hero and quirk!Monster work together is just intriguing to Kirishima. Imagine Kirishima's surprise when both of them are just as interested in Kirishima. I could keep going honestly. If you want ANY of these written out, please, just let me know and I will be MORE than happy to write out a full story for you. 🥰

Not sure if it's too much but like Kiri and the BakuSquad? Maybe like a cuddle pile with Kiri, Sero, Kaminari and Bakugou? I so badly always want to include Deku because Deku and Kiri together is just wholesome 🥰

Ren

KiriDeku pirate au? Like, they’re talking about plants or something and bonding? Or Kiri is doing work and looking sexy, then he notices Deku stealing glances and blushing real bad and they get frisky? 👀

GrooveDoe

Kirishima and Crimson Riot! (Kinks: Chastity and Cock and Ball Worship)

Naughty Boruto

Kirishima and Tamaki!!!! Dinner date where they find a restaurant which the weirdest food to see what happens with Suneater!?!?!

Colette Miller

Oh! Villain duo 😈🖤☠️ kiri and ??? I can’t decide who would the best villain partner! They’re all so good!

Kiri/tokoyami rockin the goth punk aesthetic ☠️🖤 or maybe a fantasy version kiri/tokoyami (after a battle?) Whatever you go with is gonna be ✨✨adorable✨✨ can’t wait to see what pairing and theme tickle your fancy 🤗

Tetsutetsu/Kirishima- applying suntan lotion at the beach or maybe aloe lotion after a sunburn 🥵 with tan lines and messages or pictures in contrast someone has drawn with sunscreen

Summer Bradshaw

Kirishima/Bakugo - someone in class needs to pretend to be a Villian so the class has a chance to practice deescalation and negotiation. Kirishima volunteers because he doesn’t want anyone to feel forced into the role. The costume is unexpectedly too sexy on him. Bakugo ends up flirting/trying to seduce the Villain. Aizawas now needs to explain this tactic isn’t always so effective at subduing villains.

Summer Bradshaw

Kiri getting pampered by his special other like he deserves, maybe cute and innocent (getting fed some fruit?) or maybe nsfw with some rimming? I love everything KiriBaku, but I'm thinking Inasa would be great. So maybe KiriNasa (what's their ship name? Is there one?) Or KirInaBaku... aaah so many possibilities. Anyways, let someone take care of Kiri and lavish our shark boy in love and luxury. 💕💖

Kirishima/Deku- Crimson Riot Or All Might best hero debate becomes too heated 😉 or maybe people are surprised at Kirishimas inner fanboy going toe to toe with Deku when All Might brings Crimson Riot to Class one day as a special guest but that makes Deku love him even more.

Summer Bradshaw

Kaminari/Kirishima/Sero - Kaminari & Sero “innocently” feeling their boyfriends muscles after a workout with the secret understanding they want Kirishima so turned on he opts for sexy times with them instead of doing whatever it was he was planning on doing.

Summer Bradshaw

Oooo orrrrr (I know I already gave* a suggestion sorry) an excited kiri getting to meet Crimson Riot for the first time maybe have him sign an autograph and Kiri’s all blushy or crying because he’s *so manly* 😁

Rain

Kirishima and Deku!

TheCottonCandyZombie

Kiri and Mina posing for a magazine shoot and are directed to look into each others eyes 👀 while caressing the others “horns”. Both give it a go but can’t stop laughing 😆

Summer Bradshaw

idk if this can be nsfw or not but here we gooo- TodoKiri - temp-play on kiri, and/or Todo getting scratched up by Kiri’s claws around his hips as he grinds into him KiriDeku - Deku using black whip and/or Kiri begging for/taking his dick like a pro KiriMina - getting (extra?) lewd in public, like the middle of a dance floor KiriKamiJirou - Fun backstage

Ash 🍁 Fall

a continuation of this photo https://twitter.com/syblatortue/status/1233916496990162951?s=21 (sorry I can’t make a fancy link) Deku was really turned on, and yet super thrown by the blowjob and because if that, he can’t stop thinking about it. And he’s always wanted to get a chance to get a closer look at kiris dick, so see if it can get just as hard, and to test his theory about how Kiri’s skin might taste earthy because of his quirk, so why not offer to return the favor?

w-what does PH and MS mean? ._.;

SybLaTortue

Kirideku! Kirikami! Or just some good kiridekubaku is always good 😁oh!! Or some kirikamideku! 💕

Samaj93

Best red boi! ❤ Hmm I will leave out the obligatory KiriBaku because I know we all love them already sooooo perhaps Kiri and Tamaki enjoying tasty food together? Or Kiri and Sero doing something nice for Sero's birthday (he is also born in July)? 😊

Bakugou/Kirishima/Momo.

Jovianokamigirl

Bakugo/Kirishima - snuggled at a campfire when they hear a scary noise or while someone is telling a spooky story.

Summer Bradshaw

Kirishima/Deku- middle school Kirishima was so inspired by the boy that faced the sludge villian he seeks out a disbelieving Deku to tell him how manly he is and get some tips.

Summer Bradshaw

Kiribakudekutodo

Mershark Kiri and tiger fish Katsuki?

jackanape

What about kirishima selfcest with one or more of his other Au's? Or they all could be there setting up a party to wish you a happy Bday!

Atem Morrel

Kirishima/Fatgut/Tamaki - some After-Work fun to de-stress the mighty heroes 😄

My birthday month too! *puts thinking hat on*

Summer Bradshaw
