Got this ABO universe prompt that just stays in my head
Todoroki and Iida are young childhood friends because their families status have them going to the same events and would always just stick to each other during their time together. Iida idolizes his big, strong alpha brother and claims he would also become an alpha as strong as him so when he sees a sad and lonely todoroki for the very first time he claims he will protect and care for him and to always make him smile. And with a family full of strong alphas, there is a strong chance of him presenting as one as well. So whenever they would play Iida would claim to be the protector.
“I will be your knight! I’ll save protect the prince!”
“….but I don’t wanna be saved…I wanna protect you too”
“Hmm…then you can be an adventure prince and we can save each other!”
Or the first time they play prince and knight
“Since I will become a strong alpha like my brother I will be the knight! You are so cute you can be the princess ‘Kay?”
And smol and sweet todoroki being taken aback just shyly nods and accepts but in his mind he thinks ‘but your the one that’s cute.’
But things change once their quirks came. Todoroki no longer comes over to play, no longer attends any parties and Iida cries once he realized he lost his best friend, but claims to one day find him because he is the knight and he has to save his prince.
And then it happens. The news that just shattered Tenya Iida’s dreams.
His secondary gender presented itself as…
An omega.
Everybody was shocked. Iida was growing up big and strong and he had such a strong quirk! It’s such a shame that he presented as an omega. He would have made such a good hero as an alpha. At least if he were a beta he would probably have a chance at making it out as a hero.
These words would plague Iida’s mind every time people found out he was an omega. He cried himself to sleep that night. What would his brother think? How could he ever be his equal now??
But when Iida Tensei found out his little brother presented as an omega he gave his younger brother the biggest hug and cried. “I knew my little brother was cute, but now I have to work extra hard to fight off anyone who wants to steal you away from me!”
Nothing about him being an omega was a shame or how he should give up his dream of becoming a hero. When Iida brings up his concerns his brother just gave him a determined look “ Tenya listen to me. It doesn’t matter if your an alpha, or an omega. If you want to become a hero don’t let anyone tell you that you can’t.” And with those words, Iida strived to become the stronger.
Present day Iida, with his strict work out regime had his physique strong and muscular. Nothing like how an omega is supposed to look like. No longer were the comments on him giving up on becoming a hero, well there still were but not as much anymore. Instead people started saying how undesirable he is. ‘Who would want a bulky omega? He’s bigger than most alphas I know!’ ‘He’s lucky his family is rich and they can just pay someone to marry him…but honestly who would want to agree to that? Look at him’ ‘if he were born an alpha it would have been much better, but how is he gunna attract a mate like that?’
Becoming a strong and dependable hero has always been Iida dream. It will always take priority especially since presenting as an omega he knew he had to work extra hard. He should ignore ignorant comments like those because he knows what he’s capable of. But…if down the line if he ever wants to have a family of his own….who would want him? Seeing people being confessed to? He shouldn’t hope for that. Having crushes? He shouldn’t waste his time on that anyways. He should just accept that he probably won’t ever have a partner anyways.
That is until Todoroki Shoto came back into his life. The best friend that he promised to always protect, that he always clung to when they were together, that he promised to fine one day when he was older.
The best friend that smelled so much like an alpha and confessed that he will make Iida his one day.
I can see Deku getting off on watching his alpha fucking Iida while they are in a semi-public area. (Like an alley)
Deku is a little shit who likes to crawl up into Alpha and Tenya's laps, purring and sweet and seemingly only asking for a kiss, before grinding down on them to show them that they have now been trapped.
Hello, how are you? I hope well, I'm here for BNHA poly relationships.
I like to think about a polymorous relationship with TokodekuIida, imagine this trio who have super different personalities, the way you have to manage to be able to manage their moods.
Sorry if my English is bad, I speak Spanish lol
Your English fine :)
HC: Alpha is either helping Iida manage Shouto and Deku because Deku is a feral, unhinged little monster and Shouto is very much a "I want to see what he does" sort of mate or Iida has all three of you on a leash. There is no inbetween.
I have some random thoughts and I decided to kill your time and brain cells by having you read them
I want Iida to crush my head with his thighs, and I want to see his reaction to me saying that to him. Won’t he be the cutest??
I want to lean in to kiss short haired itachis neck but right before contacting skin I actually blow a little air and walk away
I want to play family tag with kiba and our pups and the 67 doggies we have— everyone is feral
I want to “forget” to give Katsuki his goodbye smooch before he heads to work and he just waits at the door like 🧍😐
Preheat omega hiding daily essentials just to try and make you stay home with them in their cozy little next
OR preheat omega stealing the stuff you wear often cuz it smells so much like you and shoving it into their nest and god forbid you ask them for it
A/N: I kept this in my inbox so I could go a bunch of little blurbs for it because all of them deserve it. I combined the last two.
Warnings: Some NSFW, some heat stuff, some mentions of mpreg, getting body slammed by children

You don't think you've ever seen Iida's face turn so red and that was including the time he walked in on you undressing and got a full front view of what you were packing.
"I want you to crush my head between your thighs," you repeat before kissing a blooming hickey on his inner thigh, "I'm already down here."
"But-But..."your husband stutters, looking aghast despite the lewd situation you were already in, "No! I could hurt you!"
"It would be so worth it," you drawl dreamily, "Pleeassee my love? Just a little? I'll do the thing you like."
"You'll pre-sort the laundry?"
"I was thinking hand trimming the hedges so they're all even but I'll do that too."
Slick drips from his hole and you hide a smirk in another kiss against his thigh. You knew your mate too well. Doing housework was one of his biggest turn-ons.
He says nothing but his legs come up to hook on your shoulders, his thighs coming into contact with your ears.

Itachi's back was to you as he finished washing the dishes and you took a moment to admire him. He had recently cropped his hair, a change you had readily supported when you spent an hour trying to detangle your baby's sticky hand from his ponytail and then an another hour trying, in vain, to clean whatever the stickiness was out of his hair.
"I'm done with today my love," you sigh sleepily, coming up behind him and wrapping your arms around his waist, "Did you need me to do anything else for tomorrow that needs to be done now versus tomorrow morning?"
He leans into you with a gentle hum, "No but will you take first feeding tonight? I'll be up earlier than normal to run to the market before the crowds get there so I can take the early morning feeding and let you sleep in a little."
"Good plan," you nose the nape of his neck, taking a lungful of sweet smoky scent. Your hand travels down his front suggestively, "Do you want me to get you off before I crash?"
The skin of his neck flushes under your nose, his scent spiking before settling, "As much as I'd love to indulge, it would defeat the purpose of me getting up early."
"True." You pull back a little, letting him turn just so to look at you.
"Go to bed Alpha," he smiles gently, pressing a kiss to your nose, "Love you."
"Love you most," you lean forward a little, eyes focusing on his mating mark. He lifts his chin and tilts his head to the side, a knowing look on his face.
He can't see the mischief in your eyes. You blow a little cool hair against his throat and pull back completely. You murmur a little teasing 'good night' before disappearing out of the kitchen, leaving him frozen.

Not a single one of your million children know how to play gently.
"Oof," you wince as a small body collides with your ribs. Another body hits your thigh. And another hits your back.
You go down as gently as you can, twisting your body to avoid landing your full weight on any of your pups. The grass was soft but nowhere near plush enough to make it hurt less.
"Tag!"
"Tag!"
"Tag!"
"Hey! Don't break your Appa! I can't afford to get a new one," you hear your mate yell from a distance, frisbee dangling in one hand. Your older children stood with him, their own frisbees in hand. Their dogs joined them at their feet, recalling the second their training partner's attention shifted elsewhere.
Because they were such good boys and girls.
The littles paid Kiba no mind, too excited at having you all to themselves while their Oma and older siblings did some coordination and obedience practice.
"That's not how you play tag but okay," you cough, rolling onto your back and lifting onto your elbows to look at your assaulters. All three of them had Kiba's grin, crooked and reckless and wild. Your daughter's long hair had escaped its braid and you wanted to cry at how much detangling you were going to have to do later. "Appa's it."
They cheer, scattering from you in three different directions. A wet nose presses against your cheek.
Akamaru let you hold onto him as you stand up. You hide a wince as you straighten up.
'Oh yeah, that's gonna bruise," you think, giving Akamaru a kiss on the head. You look over at your mate, his face twisted into a sympathetic smile. You give him a thumbs up, kick off your shoes, and start after your little ones, their shrieks of laughter pushing you forward.

Katsuki hates when you have days off that don't align with his. He never says it but you know. He gets extra pissy when he realizes that your schedules don't line up perfectly. He's hard pressed to say it but he genuinely enjoys spending his free time with you.
You were his Alpha. His mate. His companion.
"I have half a shift this morning to cover for Dunce Face so I'll be back around 11," he grumbles, grabbing his wallet and keys while you blearily watch him move around over the rim of your morning coffee.
"That was nice of you," you yawn, "Taking over for Denki so he could see his pup off to her first day of kindergarten."
"He wouldn't stop bothering me. It was the only way to shut him up," he scoffs, his face tinting pink. You hid your smile by taking another sip of coffee. Denki's little girl has had your mate wrapped around her finger since he met her and she squared up with him.
You remember it clearly. Denki had put her down on the floor, her legs a little wobbly since walking was still new for her, and she had looked around the room to inspect all the new people she was meeting. At some point, her eyes landed on Katsuki and she decided that he was the one she needed to take down to assert her dominance.
She made a beeline right for him, putting her tiny baby hands on his knees to stare directly into his eyes as she squared up with him.
"Oh, you wanna fight?" Katsuki had growled at her, causing all your friends to chuckle. After years of being around your Omega, they knew this growling was playful. She had seemed to know it too because she growled back at him, throwing her whole body into it.
It was a great night.
But Katsuki would never admit he was doing something out of the goodness of his heart because he loved them. Nope, not your Omega.
So you finished your cup of coffee and put it in the sink, "Have a good day anyway." You stretched, popping your back, "I'm going back to bed. Patrol was a nightmare last night. Wake me up when you get back. We can go get lunch or something."
Katsuki hummed in response and you left the kitchen, padding your way back to your bedroom.
"Oi!"
You turn back around, jolting when you see your Omega charging after you, "W-"
He stops in front of you, his face twisting in irritation - the wrinkle between his brows deep and angry, "Excuse you?"
It takes you a second to realize what he meant.
A smile formed as you leaned in and kissed him. He pressed back into it, poking his tongue angrily at your closed lips until you opened them and let him in.
When he pulls away, the wrinkle between his brows is gone.

"Denki I need my wallet and the keys," you laugh, watching your Omega rebuild his nest for the third time in so many hours. The scent of his preheat clung in the air, filling your nose and lungs and invoking all the good feelings. Denki always smelt so good but Denki in preheat was perfection.
"No you don't," he huffed with a pout, turning to look over his shoulder as he splayed across the bottom layer of the nest on his hands and knees. His large T-shirt fell forward, revealing his underwear and you bit back a groan.
They were tiny little light blue boy shorts, damp around the crotch with slick. You could see the outline of his pretty little pussy, the fabric growing more translucent as his arousal grew.
"Yes I do. I have to go pick up our order," you argued, averting your eyes from the tempting sight. If you didn't stay on track, you'd end up with no food for the entirety of his heat and that was unacceptable.
"No," he huffs, turning away from you and grabbing your bed pillows, "You can't leave. I need you here."
"I'll come back," you argue, feeling a tad bit desperate because your cock was starting to show interest. Out of the corner of your eye, you see your wallet and keys at the very edge of the nest, only partially hidden under a throw blanket.
Normally, you'd never take something of yours out of the nest. You were pretty liberal with letting Denki take out of your hamper and closet, simply because he always left you with enough clothes to run errands before his heat and for after his heat when its time to do laundry.
But desperate times come desperate measures.
Denki looks at you at the same time as you look at the hidden wallet and keys and dives for it at the same time you do.
You are quicker, snatching them right as his hand comes down on them.
The heartbroken whine that leaves his mouth as you grab your treasures is almost enough to keep you in the apartment. He rolls onto his back, legs splayed open, and looks up at you with foggy, watery eyes. "Please. Don't go. I need my Alpha here."
"My poor Omega," you croon, securing your wallet and keys before getting on your knees in the half-made nest. "So needy."
This wasn't the first time this happened and even though you had what you needed, you couldn't just leave. Denki got very unstable in his preheat, slipping into mania and subspace alternatively, when left alone. It didn't matter if you were coming back or you were on your way home, he would spiral into believing you weren't coming and he was alone and defenseless.
You needed to keep him steady so he didn't panic with you gone.
"Its driving me crazy," he groans, shaking his head to clear his mind, "I'm sorry. I know we need to grab the food. I'm trying to keep my head above water but I'm so fucking horny." He looks at you with an accusatory pout, "You did this. I used to be normal. You just had to come along and give me good dick."
You snort, "Sure thing love. Its my fault."
"Would you feel better if I...." you trail off, trailing a finger over the damp patch on his underwear. You rub his clit gently, cooing as your mate jerks under you with a whine. "Maybe you won't slip under if you know I'll be smelling like your slick while I'm out."
I was thinking of my Villain Au for MHA and what sort of relationship dynamics the characters have and this is a rough idea of what I envision....in case I decided to write more of this.
Midoriya: As a villain, he is just as obsessive but his obsession is past the point of healthy. He has flashes of insanity - the fogging/sparking in his eyes as he rambles off into dark tangents/imagining his next moves/reliving his highlight reel of fucked up moments. Loves to have eyes on him and actively draws focus to himself.
His Alpha: Calm, more serious than Izuku, is just as dark as Izuku but actually bothers to hide it. Looks independent but would rather curl up in Izuku’s ribcage and live there forever to be close to him. Gets angry when separated from Izuku for longer than planned.
Shoto: Relatively the same personality but much colder. Seemingly made of ice. Unemphatic. Uninterested in most things. Finds most things not worth the time or energy. Prefers to get things done quickly and efficiently with as minimal bloodshed as possible - not because he doesn’t have bloodlust but because he doesn’t want to waste his time doing his laundry to get bloodstains out.
His Alpha: Vicious. Violent. Plays with their victims and rolls around in blood and gore until someone pulls them back. Goes berserk on command. Requires a muzzle and leash. Cannot be trusted not to pick a fight with heroes.
Iida: Roguish but not in debauched sense. Has no qualms about sex or immorality and is camp “If I want to I will. If I don’t, I don’t.” Encourages tomfoolery and debauchery even if its dangerous. Extremely confident but not boastful. Prefers to let his skills do the talking.
His Alpha: Also extremely confident. Does not let dangerous tomfoolery happen because they are responsible. Bickering is their and Iida’s love language. More prudish than Iida. Mild instigator. Doesn’t get bored often but when they do, something breaks. Clumsy.
