๐ d/s, k!nk exploration
When Katsuki casually mentioned cockwarming and Izuku looked at him like he just started making words up, the blond was shocked.

a/b/o o!kats and o!izu->a!izu, knotting and mating bite.
Omegas DkBk are together and itโs /hard/ because biology fights them during their heats, especially Katsuki because his heats last so long.
Izuku is more well endowed than most omegas, but itโs no knot.
Katsukiโs the type to finish a romance novel and go crying to Izuku about them not having a workplace romance plot.
๐ฐ: I gave you childhood friends, to ex friends, to rivals, to loversโฆ what more could you want??
๐ฅ: You never saved me from a loveless marriage, youโre useless
#dkbk
Katsuki coming home to find Izuku crying on the couch. Which isnโt unusual, really, but when he sees the blond he cries /harder/ instead of cheering up.
๐ฐ: Kacchan, they lost you!! What if they never find you?!
Katsuki looks down to confirm he is, in fact, not lost.
#dkbk

I love pervy Izuku but I canโt stop think about pervy Kacchan.
Izuku peeling off his uniform after a shift of overtime and going to shower. Katuski pulling it out of the hamper, fingering himself while shoving his face in the groin and armpits just to smell his Izuku.
#dkbk
Katsuki likes to wear Izukuโs clothes but Izuku is a nerd that buys all their friendโs pro hero merch.
So often Izuku will see Kacchan walking around in a Chargebolt hoodie thatโs three sizes too big or a Cellophane t-shirt that goes down to his knees.
#dkbk
๐ finally on their honeymoon
Katsuki is loving it, telling the hotel workers his /husband/ will carry their bags, ordering room service and putting it on his /husbandโs/ card, sitting at the bar and declining a drink from a stranger because heโs waiting for his /husband/.
#dkbk

Katsuki figures out he loves accessorizing. Rings, bracelets, earrings, barrettes, facial piercings. He loves how jewelry catches the light and sparkles. He loves the attention he gets for it.
Heโs talking about it was Denki, who also loves that extra touch.
Shy tops that cover their face while blushing and thrusting. Tops that canโt believe theyโre getting a chance with the bottom and are doing everything they can to not immediately bust.
Tops apologizing because they canโt hold back anymore.
Gimme more of this flavor please.
#dkbk
๐ish
Izuku getting hand tattoos because โKacchanโs necklace needed an upgrade.โ
And yes. Thatโs what he tells everyone that compliments the ink.
Thinking about omega Katsuki that takes his panties off at the door right after kicking off his shoes.
He wears a short little skirt too so every surface he sits onโhis couch, the bed, the counter, etcโgets a nice coating of his scent.
#dkbk
๐
Katsuki finds out Izuku is into shibari, so he buys some rope and watches a tutorial to have himself tied up when his nerd comes home.
Izuku nearly has a heart attack when he sees his baby tied with sloppy knots with the rope biting into his skin.
#dkbk
๐
Izuku has two phones. Not because he tries to separate work and his personal life, no.
Itโs because Kacchan is always sending him risquรฉ photos and he needs all the storage he can get because of COURSE heโs saving them all and NO he will not delete old ones!!
#dkbk
๐ spanking
Katsuki loves being such a brat around others bc Izuku canโt do anything to punish him until they leave.
Imagine his surprise when he acts out and Izuku bends him over his lap, tugging his sweatpants down and giving him 5 quick smacks in front of his friends.
#dkbk
๐
Izuku that never grows another centimeter from canon and Katsuki that reaches 6ft.
Their s/x tape leaks and people realize that Katsukiโs not so big and intimidating when heโs tied up with his arms secured to his calves, ass in the air, and face shoved in the mattress.
#dkbk
๐
Katsuki goes on a trip out of town but forgets to bring any toys with him. He gets the idea to text Izuku and ask how his day went. Kats then squeezes his phone between his thighs, hips twitching as text after text vibrates his phone, bringing him closer to the edge.
Phrases that just make sense:
โYouโre doing so good, Katsuki.โ
โYouโre so tight, Katsuki.โ
โYouโre sucking me in, Katsuki.โ
โYouโre beautiful when you cry, Katsuki.โ
#dkbk
๐
When Kacchanโs really feeling it, he throws his head back and squeezes his eyes shut. Maybe itโs an attempt to close out the rest of the world, an attempt to focus on the pleasure building in his gut.
But Izuku always wants those ruby red eyes on him.
#dkbk
๐
Izuku has to learn how to do piercings because Kacchan wants to be covered in them but he canโt go to a professional. He tried, once, but biting back a moan and hiding his hard-on wasnโt worth it.
Izuku doing the job means Kacchan can be as loud as he wants. ๐คญ
dkbk ๐
Katsuki telling Izuku to pull out when he finishes. He paints Katsukiโs chest and stomach with white and just stares in awe
๐ฅ: like what you see?

Thinking about the only omega in class a, Katsuki, being used to teach all the alpha show to properly take care of their future partners. Of course, their alpha teacher Aizawa takes the lead in showing them how itโs done.
Katsuki plays games with his friends, goes "afk" for a bit, and always comes back with a hoarse voice.
His friends aren't stupid, they know he's getting his throat fucked with his mic muted. They just don't say anything because they think his voice is sexy afterward.
dkbk where Katsuki interacts with a kid in front of Izuku and itโs like a flip switches in his brain.
๐ฐ: kacchan I have to put a baby in you asap.
๐ฅ: ??? Izuku thatโs literally impossible
๐ฐ: do not doubt my determination.
dkbk sfw domestic mini thread
Katsuki uses a weighted blanket and it is an essential part in his falling asleep.
He and Izuku go on vacation and their luggage is lost, including his prized blanket.
Izuku blushes every time. He loves hearing it just as much as Katsuki loves saying it.
When Kats dresses up in pretty white lingerie and rides Deku on their heart shaped bed, he canโt hold himself back.
โLook at my perfect /wife/, so pretty for me.โ
Katsuki instantly comes.
#dkbk
๐
Katsuki is definitely the type that jokes about k!nks he thinks are weird until Izuku gets the โhintโ and acts on them.
Katsukiโs quick to find out that things that start as a joke usually end up much more real than heโd want to admit.
#AiBaku
๐
Shouta always keeps a hair tie on his wrist for an impromptu times he wants to eat Katsuki out.
The problem is that now Katsuki gets turned on whenever Shoutaโs hair is pulled up, even if heโs just tying it back so he can make dinner.
#dkbk
๐
I dunno I kinda like hyper-sexual Deku with grey/ace Katsuki. Not in a way that Izuku would pressure Kacchanโbc he would NEVERโbut just those carnal craving vs โcontent with being be near youโ mindsets learning to adapt to one another.
๐ฅ: why did you never confess to me in middle school with chocolates?
๐ฐ: โฆkacchan do you really think you wouldโve accepted a confession from me in middle school?
๐ฅ: I GUESS WEโLL NEVER KNOW
Bonus points for it being omegaverse and alpha!Izuku purposely scents his uniform in the hopes he can trigger omega!Kacchanโs heat.
It does.
Izuku comes out of the shower to a slicked up omega crying because his fingers are too small and he needs his alphaโs fat knot.
I feel like after the war, Aizawa wonโt let Bakugou out his sight. Like, heโs not even allowed to be on Aizawaโs right side bc of his blind spot.
Must be within arms reach. Must be on the left. Must be protected at all costs.
#dkbk
๐
I feel like Katsuki would make an off hand joke about getting his nails done and Izuku would immediately do all the research he could, buy all the materials and practice every night so he can do Katsukiโs nails.
Heโs not about to let a random tech hold Kacchanโs hand!
#dkbk
๐ cw: mpreg and maybe mild dubcon?
We all know and love pregcchan begging to be railed and Deku frantic about the baby, but consider:
Izuku is so amazed he actually got Kacchan pregnant that he's fucking him harder than ever.
๐ฅ: Izu, easy, the baby
๐ฐ: *goes faster*
cw mpreg , lactation
To continue my aibaku thought from yesterday, what if Katsuki gets pupped from all these lessons and then heโs the perfect model for omega pregnancy.
dkbk mini thread, ๐ suggestive, aged up (pro heroes)
Dkbk finally get together and Izuku isnโt shy about using pet names for Katsuki in public or around their friends.
Izuku literally pouts for days until Katsuki brings home the prototype the manufacturer gave him to approve.
Weeks later the original package arrives.
Now Izuku has two little Kacchanโs to look at while Katsukiโs out of the house and one real Kacchan to hold when heโs home. ๐ฅฐ
#dkbk
Every time Izuku successfully makes Katsuki laugh, he gets so mad. Smiling and giggling one second and the next heโs telling Izuku to STOP BEING FUNNY, his face red because heโs embarrassed. Literally so in love.
Izuku even apologizes but rly Katsuki enjoys it. Tsundere.
#dkbk

Deku is definitely graduating a virgin bc no way in hell is Kacchan gonna get railed in his obnoxious American-core room. And no, Katsukiโs room isnโt an option either bc thatโs his sacred place.
Imagine Kirishima stops by unannounced and is greeted by a sleepy Kacchan in Red Riot sweatpants that are tied so they donโt slide off his hips.
Kiri crying saying supporting his friends is so manly and Katsuki restraining himself from blasting his quirk in his friendโs face ๐คญ
More omega Katsuki brainrot: I think he has multiple hampers. One is specifically for his alpha. He expects all his alphas work out clothes, underwear, and socks. Itโs a heat prep basket so his nest can be filled with the strongest alpha smells ๐ฅฐ

Katsuki is the type to act overly confident and then get caught off guard when Shouta agrees.

Little!Kacchan telling cg!Izuku he loves him the 'mostest of anything ever' after a few back and forth 'I love you more's
Daddy Izu concedes only to be met with wobbling ruby eyes.
๐ฅ: How can I love you mostest when I'm small?! You're big! You have more to love!
"Can't help it, Kacchan surprised me," Izuku sheepishly replies as he scratches the back of his head. "Maybe... we could practice. Try again?" His eyes flick back towards Katsuki with a glint of hunger.
Katsuki grins back.
"You're fuckin' on."
The mating bite doesnโt fade this time. Katsuki is sure to wear loose shirts or waltz around shirtless, proud of his permanent show that he is claimed.
#AiBaku
๐ daddy kink, balls, and a sprinkle of d/s
Katsuki loves to suck on Aizawaโs balls but theyโre so big he can only ever get one in his mouth :( he wants to swallow them both and he tries so hard, covered in his own drool and tears rolling down his cheeks in frustration.
He quickly cuts the rope and tends to Katsuki's skin, kissing the wounds.
He teaches Katsuki properly and ties him up nice and pretty, ropes never too tight and always with the cleanest execution.

Denki: would you rather give up spicy food or blowjobs for the rest of your life?
Katsuki: oh, easy, blowjobs.
Denki: wow, you really like spicy food that much? I donโt think I could give up bjs.

Izuku is definitely the type to be relaxing at home and start thinking about Kacchan and immediately get hard. Heโll touch himself until heโs leaking and aching for release and then search the house for his love.
tmasc!Deku x fem!Kats
Izu waking up from top surgery and looks over to Kacchan, her shirt a deep v-neck that shows off a LOT of cleavage. Like more than Izuku has ever seen.
๐ฐ: K-Kacchan, yourโyou have um, you lookโbigger?
๐ฅ: What do you think they did with your tits, Deku?
Izuku assumed Katsuki would be embarrassed after the post-nut clarity hit, but instead she just pouts that it took him so long to actually pick up on her wants.
One toasty bottom later, Katsuki is a lot more eager to communicate her wants directly.
Katsuki just smirks.
Itโs truly the only necklace he wants: custom fitted just for him, one of a kind, absolutely perfect.
Poor Denki just wants to go one day without being subjected to their gross PDA
#AiBaku

Katsukiโs always in a good mood when he comes to work in the morning but when heโs away on a mission with his sidekick, heโs practically brooding in their hotel room.
He calls Aizawa, uncaring if the sidekick eavesdrops.
He even goes a little extra when heโs in pre-heat, grinding his bare cunt on anything he can.
His alpha certainly appreciates it, the whole house smelling like a needy omega ๐ฅฐ
Thinking about tmasc!Katsuki using his cis boyfriend Deku to improve the accuracy of his gay fanfic. Just grilling him on all the things his dick can do, testing how many times he can finish and get it back up again, staring at him as he gets hard.
Itโs important research!
And maybe Katsuki evens the playing field when Izuku gets his vertical labret done and Katsukiโs aftercare instructions include a steamy make out session in the piercing room.
dkbk dom/sub
Kacchan is the one to tell Deku he wants them to lean into a dom/sub relationship. Izuku is all for it, does his research, discusses their boundaries, pays attention to the reactions he gets from Kacchan whenever they try something new.
Honestly, heโs a natural.

Day 5: Jewelry and Piercings, bringing back my piercer AU for some yummy feminized fun!
Katsuki looks at the clock for the millionth time today. His leg bounces in anxious anticipation knowing any second now Izuku is going to walk through the door.
Izuku had told everyone prior to ensure he wouldnโt make anyone uncomfortable. Katsuki apologized for his behavior to everyone and had many more spanks waiting for him when they were alone again that night.
Iโd like to say Katsuki learned his lesson, butโฆheโs a brat to his core
It works so well that itโs his go-to method when theyโre forced to spend time apart. It basically Pavlovโs himโ every time he asks Izuku about his day, Katsuki feels heat pooling in his gut.
#dkbk
NYE
Every year Katsuki is /adamant/ that he isnโt kissing Izuku when the clock strikes midnight. Itโs too fuckinโ cheesy!
โฆbut heโs also a lightweight and Izuku might slip an extra drink in his hand at 11 to guarantee a passionate kiss when the clock chimes.
โover a plastic version of him.
He kicks off his boots and struts over, plopping himself in Izukuโs lap.
๐ฅ: Who needs cheap plastic when you get to hold the real thing?
Izuku just cries harder as he hugs his boyfriend.
๐ฐ: Me!! I need all the Kacchanโs!
He works fast so he isnโt caught, which adds to the adrenaline. He doesnโt pay any mind to the eyes watching him through the crack of the bathroom door.
Izuku is well aware of his boyfriendโs habit and often turns the water on without getting in just to watch the show.
#AiBaku
๐ Bored & Ignored
The sound of Shouta unlocking the doors to their home immediately has Katsuki perking up from his spot on the couch. Katsuki crowds him and takes his bags, damn near throwing them aside.
๐ฅ: What the hell are you talking about, Iโm literally right here
๐ฐ: The new figure!! The chibi Kacchan figures on a limited run! Itโs lost in the post and I might never get to hold little Kacchan!!
Katsuki takes a breath and centers himself. His boyfriend is actually cryingโ
โOpen your eyes, baby, donโt you wanna see what youโre doing to me?โ
And Kats listens. He blinks tears out of his eyes and takes in the furrow of Izuโs brow, the sweat dripping down his temple, the flush staining his cheeks.
The view makes him never wanna close his eyes again.
#Aibaku

Katsuki writes teacherxstundent fanfic thatโs definitely *not* about Aizawa
Shouta reads it and subscribes to his account bc is the only author heโs found that writes characters like him and Bakugou, his guilty fantasy
#dkbk

I hc Katsuki as a lightweight but also an affectionate drunk. Like, two beers in and heโs a koala latching onto Dekuโs side.
Maybe Deku appreciates the PDA and offers to buy him extra shots on a night out.
Maybe he knows itโll end with Kacchan on his knees later.
Denki: You never wear a necklace, though. Thatโs all you need to complete your look! You need a choker like I always wear!
Izuku overhears and walks up, gently wrapping his scared hand around Kacchanโs throat.
Deku: This is the only โchokerโ Kacchan needs, thank you.

Katsuki packs their luggage for vacations bc the one time he let Izuku handle it the perv packed him nothing but panties.
That wasnโt the problemโKatsuki loves wearing them, but they were all red and lacy and showed through the white pants he wore for their photo shoot
#AiBaku
When Katsuki breaks the top ten, his former class arranged a night out to celebrate. Naturally they invite their teachers as well. Katsuki has one too many drinks and finds Aizawa in a corner alone.
Another shot for courage and he takes the empty seat beside him.

afab terms for trans masc Aizawa and Katsuki
Shouta is a bit more reserved. He and Katsuki have fooled around for a while but he never takes off his boxers.
Teaching proper lessons of omega care wasnt in UAโs curriculum, but Aizawa couldnโt resist taking the chance to claim the perfect omega for himself and refused to let him slip away ๐ฅฐ

Imagine Katsukiโs class comes back to UA after graduation to play a game of baseball with Aizawaโs newest class.
Katsuki plays as first baseman and Shoutaโs beside him giving signals to his students for what play to make.
Cuck!Izuku really loves watching aibaku going at it like rabbits. He doesnโt even have to touch himselfโthe degradation spilling from Shoutaโs lips is enough to make him nut without touch
#dkbk
Imagine airhead Kacchan on a date with s/daddy Izuku and heโs raving about the umami flavor of the dish theyโre eating and Katsuki just looks at him blushing and goes
โDonโt call me mommy at the dinner table! Save it for when weโre back at your place!โ
Katsuki canโt tell if heโs disgusted or turned on.
But he does twitch in his pants when Izuku looks up at him through green bangs and coos โYouโre sitting so well for me, baby, keep it up.โ

๐ฅ: โฆ are you jealous of the man that saved my life?
๐ฐ: โฆ all Iโm saying is youโre the only man in my heart
For now, he appreciates the afterglow with Katsuki, holding him close as he pets his head and compliments his good boy.
He takes a moment to appreciate the charm on Katsukiโs collar, reading โDekuโs Perfect Pupโ.
He really does have the most perfect pup, all to himself.
Katsuki getting upset, but heโs trying to be less aggressive so he calls the โshitty extrasโ just โstinky losersโ and Izuku canโt help but coo at his boyfriendโs pouting, teasing him for sounding like heโs reading a childrenโs book instead of venting
Katsuki being so unknowingly soft and sexy that his partners always lose control over their quirks.
A simple, yet unexpected kiss on lips. A look of devotion and tenderness as heโs bent in half. A bubble of laughter that escapes from him.
Theyโre so desperate to see more.

Many thoughts about fem!Deku being Katsukiโs domme.

Her making him walk around on his knees because heโs taller than her.
AND AND when heโs a good boy, he can pick the attachment for her strap ๐คญ๐

๐ actor AU
Katsukiโs older off screen but because of his height and youthful features he snagged the role of Shoutaโs student.
It changes their sex life because Shouta canโt help but steal one of the high school uniforms so he can play out his dirty fantasies at home.
The problem now, however, is that even after they get home and replace Katsukiโs weighted blanket, he still demands his Deku Blanketโข๏ธ any night they get to spend together.
But maybe itโs not that much of a problem anyways.
