cw: age-gap, PH!Deku &QL!Katsuki
Prohero Deku became a teen parent at the young age of 15 and raised his baby girl by himself with his mom’s help. Now at age 30, people try to use the excuse that +
—————
“Don’t baby me. Don’t try to act like you’re my mom. I /know/ you just want my papa’s money so get lost or I’ll do worse next time I see you.” a green-haired girl sneered.
With the same curly green hair, and freckles sprinkled across her cheeks, no one could deny that she wasn’t the prohero’s daughter.
Overall, with her gifted looks she could be described as beautiful as a doll, until she opened her mouth.
“You stupid brat! Wait ‘till your dad finds out what you did to his girlfriend!” The bleach blonde shrieked.
It didn’t take too long for Keiko’s dad to come home from patrol. That’s when the real show began.
“Keiko sweetheart, do you have anything to say?” Her sweet, precious dad asked gently.
“See! That wretched child should be sent off to boarding school, Honestly! I don’t know how she’s your child with that terrible personality of hers!”
“Wha-what?! You’re kicking /me/ out for telling the truth?!”
And that was how Keiko had yet again ruined another one of her father’s relationships.
Both men and women flocked him, wanting a piece of his fame or money. They didn’t actually care for her dad and like hell she was going to let them use her dad like that.
All attempts lead to the same result— them getting kicked out of her and her dad’s life.
But she really didn’t care about that.
Keiko didn’t need all these strangers coming into her life and pretending to act like they cared about either of the two.
But until then, Keiko would do her job of keeping away gold diggers.
—————
His girlfriend at the time wanted nothing to do with the daughter she gave birth to and handed her off to him.
It was hard. There were days where he wanted to give up, but thinking of his daughter, the love of his life, pushed him to do his best. He wanted to give her the best future that he could.
He almost wasn’t sure how he graduated high school, much less started working as a sidekick.
Due to the lack of money, he’d sprint every morning to drop his baby off at his mom’s house before picking her up after his shift ended.
By the time he was promoted to hero status, his baby girl had already started elementary school.
He loved his mother, but the feeling of being able to provide and take care of his daughter on his own gave him a sense of accomplishment.
Unfortunately, along with the fame came the obsessive fans.
They made him wonder whether his daughter would truly appreciate having another parent in her life.
Except his daughter never liked any of his partners.
His daughter was a smart cookie who could read people like they were books.
If his daughter didn’t like his choice in a partner then there was no point in staying with them.
But until then, He’d do his best to keep his daughter happy by himself.
—————
Katsuki was a tired, tired student. At the age of 22, he was in his final year of being a mechanical engineering student at Yuuei University.
So Katsuki graduated high school with top scores and got himself enrolled in college.
However, college meant lots of money needed.
That was why when he got a call to come in to work on his day off, he did so reluctantly.
“It’s whatever. Which tables do you want me to cover?”
“Why don’t you do the few tables by the windows and the back?”
And he went right to work taking orders and serving food.
As the day went by, all kinds of customers came in and out. He didn’t have time to look at people’s faces correctly since he was rushing back and forth.
Either they complained about their food to get a freebie or they’d straight up have an attitude problem with him.
It was more work for him having to deal with unruly customers so he was thankful when there wasn’t any.
A sleazy guy with greasy slicked-backed hair was harassing what seemed to be a teenage girl.
So Katsuki grabbed the nearest item he could find, which happened to be a drink tray, and bashed it against the guy’s head. It took attention off of the girl, allowing her to escape the harasser and hide behind him.
“You fucking punk! I’m gonna get you fucking fired! Just wait till I tell your manager about this!”
As if those were the magic words, his manager appeared out of nowhere.
“What seems to be the problem?”
His manager looked panicked. “Of course sir, you will be compensated but—”
The greasy dude opened his mouth to speak again. “Compensate me or I’ll sue your asses. I’ll take this to court!”
The harasser scoffed. “Oh yeah? A little girl like you is gonna take me to court?! Don’t make me laugh!”
Katsuki saw the creep and his manager choke up while the teen’s face brightened up.
“P-papa?!” the creep and his manager stuttered out at the same time.
He was just a really tall, really buff guy who looked like he could snap the blonde in half.
It must have been noticeable on his face because the teenager beside him burst out laughing.
Katsuki felt himself hunch up. He didn’t want to lie and say that he did have a strong quirk, but people’s reactions to him being quirkless were never good.
He was expecting the teen to pity him, or curse him out. But instead she just squealed and pulled him into a tight hug.
“Another?” Katsuki questioned.
“Yup! I’m quirkless! A shocker right? Prohero Deku’s daughter doesn’t have a quirk? But I'm fine with that. I’m just glad to meet someone else who’s like me!”
“Thank you for saving my daughter before anything else could happen. Can I treat you to coffee to show you my appreciation?”
Prohero Deku just asked him out to coffee as a thank you.
The prohero gave him a bright grin before asking for Katsuki’s contact information which he passed without saying a word.
He needed to get some sleep before he could process whatever happened today.
—————
It was supposed to be a nice celebration with just the two of them but as she was going to the bathroom, she realized she was being followed by another customer.
He cornered her near the bathroom, asking her for sexual favors.
He ignored her attempts of being nice and proceeded to try and grab her body. She backed away in time, but that allowed him to push her into a corner even more.
While he was down, she made her way past him and hid behind the waiter.
Her papa went off to solve the issue as she stood near the waiter.
Keiko was trying to think of something to talk about with the waiter who saved her when she saw his jaw drop. She turned to look at what caused him to react to that, only to see him staring at her dad.
The thought of someone taking so long to recognize her dad was almost so absurd, she burst out laughing before thanking the blonde for his help.
Except the conversation didn’t go how she thought it would go.
Instead, she found out he was quirkless, just like her!
To just find someone who had also gone through similar things that she did, except it must have been worse for him.
She didn’t have time to bring up anything else though, because her dad showed up.
She could see the subtle blush on her dad’s face, and for once she didn’t feel the need to oppose.
And maybe it was the bond of them both being quirkless, but she wanted this relationship to be successful for her dad.
Maybe this was the one who would help her dad finally be happy.
—————
Maybe it was the fact that his daughter seemed to like the blonde.
Or maybe he was attracted to the blonde because he seemed so down to earth.
A few nights ago, he had texted the blonde to meet up for coffee today. And since then, Keiko hadn’t stopped talking about it.
In fact, she was so excited, he let her choose out what clothes he should wear. Her choices didn’t disappoint him.
The two of them tried fixing his hair, but there wasn’t much he could do with the mess he called his hair.
He made it to his coffee meet-up (it wasn’t a date. He was just thanking the attractive waiter for saving his daughter) and sat down in a corner where people wouldn’t see him.
The pretty blonde showed up a few minutes after he sat down and looked around for Izuku.
The blonde immediately went to him and sat down.
“Hey! I’m so glad you could make it.” Izuku gave him a soft smile.
“Don’t be nervous, I don’t bite unless you want me to.” Izuku leaned closer to the younger male, slightly smirking when he saw the blonde blush harder.
The greenette just laughed. “Of course you’re not. I’m Izuku Midoriya by the way.”
“....I know who you are, tch. I’m Katsuki Bakugou.”
“Your daughter’s strong. You raised her well.”
This was the first time someone he was attracted to not only asked about Izuku’s hobbies, but also asked about his daughter.
It didn’t help that Izuku wanted to see more of that pretty blush of his.
They settled on a matcha latte for himself, a chai latte for Katsuki and a plate of club turkey sandwiches while they continued their conversation.
He wouldn't have been accepted without more than a support student graduate diploma due to his quirklessness.
The coffee hang-out ended with Izuku actually asking him out.
Katsuki blinked at him a few times before answering with a small “sure”. Like the gentleman he was, the freckled hero took the younger male back to his residence before driving home.
—————
“Well? Well!? How was it?”
She saw her dad blush. “Well, we got along well so I asked him out for an official date. Should I take him somewhere fancy or casual?”
Her dad agreed on her judgement and the two brainstormed ideas for where her dad could take the blonde.
Her dad was lucky her great senses were available to him. Without her, he would have never gotten past deciding what kind of restaurant they should go to.
On all his other dates, he looked miserable, as if he was doing some chore he hated.
This Katsuki guy must have really been something special for her dad to be so happy.
This was all for the happiness of her precious dad.
—————
He wore a tight white button up with a few buttons unbuttoned and the sleeves rolled up and paired it with black slacks that emphasized his thighs.
Once he was done, he modeled his look for Keiko, who gave him the final approval and he headed off to the restaurant.
But apparently the blonde had similar ideas because both of them arrived at the restaurant pretty much at the same time.
Izuku didn’t want to take his eyes off of the gorgeous man but forced himself to, in order to not look creepy.
Katsuki smiled and opened his mouth to reply, but just as he was about to say something, a waitress came up to them and led them to their seats.
The whole time Katsuki kind of looked nervous.
“Uh… yeah. I’ve just never been to a restaurant /this/ fucking fancy before…”
“Ah, I see… I guess I forgot to take that into account. Keiko and I thought this would be a good restaurant since it wasn’t too fancy.”
“Yup! She didn’t want you to be uncomfortable on our date and I apparently can’t pick good places.”
“Oh? If you chose the place where would you have had the date?”
“...isn’t that the Michelin star restaurant? The really expensive one with kobe beef?”
“Yup! It is. I’ve been there a few times, it’s pretty good.”
“Hey! Was my choice not a good place?!”
“It’s too fucking much. Once again, thank you for your daughter.”
The two talked for hours while finishing up their meals. They spoke of all kinds of things too.
For once, he didn’t feel like a walking wallet but a person too.
—————
After the first date, they had a few more dates before Katsuki officially became Izuku’s boyfriend. And while that didn’t sound like a big deal, to Katsuki it was.
After all, no one wanted to date a quirkless person like him before.
And he wasn’t so interested in dating other people before Deku either.
The biggest change was his personal time decreased a lot.
He spent most of his time with Izuku and if Izuku was away for work, he spent his time with Keiko.
Most days if he wasn’t at school or work, he’d be at Izuku’s house with Keiko.
Of course not all days were like this.
Other times they would eat Katsuki’s meals but instead of cuddle time with Izuku, the two men would have a bit more “fun”.
That was a type of panic neither man ever wanted to go through again.
To be fair, it was because Katsuki’s parents wanted him home for the holidays, meaning he had to leave Izuku and Keiko for a week.
This was the first time since he and Izuku started dating that they would be apart for longer than a day.
And that’s when the trouble began.
Ever since they started dating, whenever he saw Deku’s name being mentioned, he’d look at it.
So he scrolled back up and what he saw was nightmare fuel.
“Foreign Model and Deku’s Ex-girlfriend, Makaeyla Mckenzie, Spotted with the Hero: Couple Back Together?”
When she was leaving the number one hero’s house, the two were spotted kissing by the door.
Katsuki felt numb.
Did Deku cheat on him? Was he not good enough so Deku needed to cheat on him? He thought their relationship was working out so why did this happen?
What did he do wrong?
After all, who would want to actually date a quirkless person?
The hero probably got off on knowing how powerless Katsuki was.
He ended up sending Deku a single message, “Don’t ever talk to me again.” and then proceeded to block the hero.
It was for the best.
His parents didn’t even mind his sulking. They knew how much the relationship meant to him.
It was a good distraction from keeping his mind from thinking about Deku and how he missed being held and how he missed the prohero’s smile and how he missed Izuku.
He was in the middle of finishing an essay that was due in a few weeks, so he decided to take a break and see who the fuck was annoying him.
Unfortunately, he wasn’t fast enough and Keiko managed to jam her foot in the door enough to push the door back and enter his home.
“It’s for a good cause!” Keiko argued.
The younger girl proceeded to drag him to his own couch, point at it, and tell him to sit. He did so with a lot of grumbling.
“And who the fuck do you think you are?! Your dad and I broke up, remember??”
Katsuki sighed before telling Keiko to go on.
Oh.
Oh shit.
His (ex??) boyfriend probably already felt so bad about the whole situation and Katsuki just had to make it worse.
Fuck!
“...Yeah. We need to talk. I need to apologize to Izuku too…”
By the time he was out, there was a small stack of clothes sitting on his bed, which he got dressed in.
Once he changed into it, he went over to Keiko who was sitting on his couch, playing with her phone.
“Yeah yeah, I don’t mind. Thanks.”
Looking around, everything seemed normal.
No matter when Katsuki came over, the house was never quiet. There was always some sort of sound.
He crept up the stairs and made his way over to Izuku’s room. Gently he knocked and opened the door.
“Keiko, not now please. I just want to be alone.” came Deku’s voice.
“I’m not Keiko, dumbass.”
The greenette had bloodshot eyes as if he was crying. His usually clean-shaven face and stubble growing. His hair was messier than normal too.
“Yeah, I’m here Izuku. I-I’m sorry. I should have let you talk instead of just cutting you off like that. I—”
The two went back and forth apologizing.
She went past them into Izuku’s room and placed the tray on his desk.
“Yeah of course sweetie. Just be careful and call me if you need anything.”
Once she left, Deku shut the door and turned to face the blonde.
“Kacchan I—”
Katsuki felt himself being lifted into a bridal carry as Izuku took them both to his bedroom.
Izuku had his arms wrapped around Katsuki’s waist while Katsuki was curled into the prohero’s chest. The two snuggled into each other as they traded gentle pecks with one another.
“You sure you want to do this Kacchan?”
“Babe, I haven’t had any fucking dick since break started. I need you now!”
Grabbing the lube, he coated his fingers in a generous amount before making his way to the blonde’s spread legs and winking hole.
“Mmmh~ so good!” The blonde mewled.
Once, Izuku was sure Katsuki was thoroughly stretched out, he curled his fingers.
“You doing okay Kacchan?” Izuku grinned down at his lover.
“Fucker, you didn’t even put it in yet.” The blonde pouted.
Katsuki must have taken that as a challenge because the blonde male quickly got up from laying on the bed and got on his knees.
“Kacchan, take it easy. You don’t need to do this.”
So Izuku sat back as his boyfriend took all of him in his mouth, without gagging.
The blonde bobbed his head as he sucked and licked all of Izuku’s length before pulling off of the impressive length.
The blonde gently sucked the head, swirling his tongue around a few times before pulling off and with his hands, pumped the length.
“Hmm? Aren’t you enjoying this, I-zu-ku? Or do you just want to fuck my mouth?” He could see Kacchan’s eyes twinkling at the thought of a challenge.
The younger male just grinned.
“Mmh!” He heard the blonde squeak, but he didn’t feel any taps on his leg so he continued.
Kacchan moaned and hummed as he was face fucked. Izuku moved his hand so he could grab the blonde by his hair as he slammed himself inside the blonde’s mouth.
After a few more thrusts, he came down the blonde’s throat.
Once all his seed went down the blonde’s throat, he pulled out and gathered the blonde in his arms.
“You’re so good for me Kacchan. You did so well! How are you feeling?”
Izuku massaged the blonde’s cheeks gently. He didn’t want Kacchan’s jaws to be aching later.
“More. I want more Deku. Can you fuck me? Fuck me please!” his boyfriend pleaded.
And who was Izuku to deny his boyfriend?
“Nnnnghh~” the blonde moaned as he nodded for Deku to move.
The greenette started off gently, rocking his hips, thrusting shallowly before thrusting harder and harder.
“Ahh~ Zuku! So good!” Katsuki tried covering his mouth with his hands as he let out a muffled moan.
“Don’t fucking cover up your moans! Let everyone hear how much you’re enjoying yourself baby.” Izuku snapped his hips up against Kachan’s plush ass.
The blonde looked fucked out, tears gathered in the corner of his eyes, as drool ran down his open mouth. His eyes gained a hazy look in them.
“Shit! Kacchan look at you, you look so hot. Fuck! Cum baby, cum for me!” Izuku groaned as he came inside the blonde.
As much as Iuzku wanted to join his lover in bed, He had to clean up first.
Afterward, he filled the tub with warm water and gathered a dozing Kacchan in his arms.
After drying him with a fluffy towel, the greenette dressed his boyfriend in a large shirt of his.
Once that was done, he gently lowered the blonde into the clean bed and crawled in next to him. He wrapped them both in a soft blanket.
Right before he fell asleep, he kissed the blonde’s forehead muttering “I love you”, and he fell asleep dreaming about what it would be like to have Kacchan in his life forever.
