Katsuki and Eijirou weren't strangers to the weird world that was shipping. After all, 'DynaRiot' had been a tag on twitter since they'd left school, as people could see how close they were on national television pretty much every day, even as they were not physically together most of the time. Despite their actual relationship being secret to pretty much anyone, it was still funny how random people were able to analyze all the wrong things to somehow get to the right conclusion.
But 'DynaRiot' didn't only come on twitter as an hashtag for cute edits of the two pro-heroes (that both Eijirou and Katsuki saved on their respective private profiles unbeknown to the other); nope, it was so much more.
The first time Eijirou had discovered fanfiction, it had been thanks to Midoriya. The two men had had quite the rough overseas mission together, and when they'd pulled to the hotel room, both of them had just wanted to sleep for the next twenty years. Unfortunately, though, debriefs were due, and soon they'd found themselves sitting on Eijirou's bed, each other's bodies as their only support not to succumb to sleep.
"Hey, Kirishima-kun?"
"Mh?" Eijirou hummed as he'd noticed he'd almost dozed off.
"Did I ever tell you about the time Kacchan almost found out about my Ao3 account?"
And oh. Midoriya knew that anything regarding Katsuki had him completely aware in a second. That's when he heard chuckling—okay, maybe he'd showed his eagerness to know more about his partner's past a little too much, but they'd been together for almost five years and he was still very in love and very interested in anything regarding him, sue him.
"No?"
And wait.
"Ao3? What's that? Is it some weird website for All Might obsessed teenagers?" he teased as he clasped Midoriya in a light headlock.
As the other freed himself with a chuckle, he replied, "you could say that. At least for me it was," he said, still trying to contain a giggle. Eijirou just watched him expectantly. He really, really wanted to know about Katsuki and this weird website. "The thing is, it's not just that," Midoriya added after a couple of seconds. "Give me a second and I'll show you."
The man shuffled from the side hug Eijirou was keeping in and went to grab his phone from his own nightstand where it lay charging. As he got back to the original position against Eijirou's arm, he unlocked it, and Eijirou couldn't help but to notice how his lock screen was a picture of him and Katsuki all beat up, but laughing, after they'd fought over something petty—and if Eijirou knew exactly where that photo came from because he'd been the one to take it without Katsuki knowing, that was a story for another time.
Midoriya quickly found the website, and soon began inserting his own login credentials. As Eijirou diverted his eyes not to pry, he sneaked a couple of good night texts to his partner, hoping he hadn't already went to bed.
Soon, however, Midoriya was done, and he opened a section called 'bookmarks'. "See, Ao3 is a website where you can write fanfictions. Pretty much new stories about characters that already exist, but some people also like to write about real people, especially heroes."
Eijirou could see his friend's cheeks tinting slightly with red, but didn't comment on it. "Well... I was one of those people," Midoriya chuckled. "I think you can understand me when I say awkward middle schoolers always find the weirdest coping mechanisms, can't you?"
And, oh if Eijirou could.
He voiced so, but he was too entertained now to bring up his own... methods. So he urged Midoriya to go on.
And he did. "Well, I don't think it's a secret that I've always been All Might's biggest fan—and don't tell Kacchan, he still thinks it's him after EVERYTHING,"—and hell if Eijirou didn't know that already—"Well, I was also alone and had some power fantasies so I pretty much started writing so many fanfics about myself, without never using my name, getting saved by All Might in different situations—weird how that pretty much turned out to actually happen, now that I think of it," Midoriya said without much as catching a breath.
Eijirou was already knee deep in this and really wanted to know about Katsuki, especially since his partner never talked about his middle school days, if not among tears and snot and guilt that had never actually washed away.
Eijirou exhaled.
"I think it started around the first year of middle school, and it was a secret I dared telling no one." A pause. "Not like I'd actually have people to tell to, but I'm digressing." A ghost of a grimace in his smile.
Eijirou bit his lip. "Hey, man, if it hurts, you don't have to-"
"No no," Midoriya interrupted him. "It's funny I swear. And if I have to be honest, it makes me happy to think how far we've all arrived, how everything changed since we began UA." His expression had shifted, he was telling the truth.
Eijirou hummed in agreement.
"Well, getting back on track. One day, I was eating my lunch in the classroom, and since I was alone, I was buried deep in writing the new fanfic I had just brainstormed—it would have been fun to let you read them if I hadn't canceled all of them in a fit of embarrassment just after I'd started training with All Might, scared he could have discovered them, though," he said scratching the back of his head.
It was then that the two men watched each other and burst laughing at the idea of a 50 something old All Might knowing and reading fanfiction, especially of himself! Yet, as the fit subsided, Midoriya started his story again. "You know how I get when I get my mind too into something, and that's how I was... Which meant I did not hear Kacchan arriving, like, at all." He chuckled again. "He was all 'What'cha writing about, nerd?'"—and Eijirou cracked up at the impression—"And, Kirishima-kun?"
"Mh?"
"You can't understand how high I flew in the air." Okay, they were both wheezing now. "I actually thought I had finally developed a quirk, I swear!" he said through tears. "I'll never forget Kacchan's face, at this point I think he probably thought the same-
"Obviously, though, he wasn't one to let go and soon began pestering me to show him, but I was gonna take that to my grave, I'd sworn.
"This means that absolutely no amount of threatening had my walls waver, and I actually stood to Kacchan—or, well, I had the promptness to pretty much evaporate before he could even think of doing anything."
Eijirou was dying at the mental image of a young Midoriya bolting out of the classroom to protect his stories about All Might from a feral murderous baby-Katsuki that-
Wait.
His eyes soon fell to the still lit phone, open in the bookmark section. "Is that about me and Bakugou?"
And if there was even the tiniest doubt that Midoriya had invented the story from scratch, now, seeing him seemingly mastering 'float' again, washed away every single one.
"Dude."
"That's not what it looks like," the man tried to save himself, but there was no actual strength in it. It was absolutely what it looked like.
"Lemme see-" Eijirou snatched his phone to take a look, but soon Midoriya tackled him to get it back. "Fuck, bro, what are you reading about us that I can't see? It's not like it can be that weird."
As it turned out, it wasn't that weird, but reading about what people thought of their relationship made his heart swell, and his lip tremble for half a second at the thought they couldn't actually be out, not when the actual world wasn't so perfect like in fiction.
Maybe he could tell Midoriya in the future, though, who knows.

And that's how, now, two weeks later, Eijirou found himself panting under Katsuki's relentless thrusts after they'd just tried recreating what they'd read together in a fic.
"Ah! Ah… Babe... I-" Eijirou was in Heaven, feeling Katsuki deep into him made him always feel so blessed. He was drooling, his eyes heavy-lidded as his hands clasped at Katsuki's hair. He realized then he must have been quite the sight.
"Eiji... Love- I'm close..." Katsuki's words before his release had him tumbling over the edge as well, and soon they found each other's lips to seal whatever moan and sound they were making to be sure it all stayed between them.
"I... I love you, Kats."
"I love you too, Eiji," Katsuki said as he cupped his cheek reverently. "I love you more than my own life."
Eijirou just grinned and linked their lips again.
—
It had been such a shit day. Eijirou had almost risked losing two civilians' lives and somehow the press still couldn't understand his bad mood. He wanted to lash out. He wanted to cry, yell, punch through a building as if he hadn't done that all day long. He wanted to go home.
But he still had to go through the press. Fuck.
It took him another two hours of fake smiles and aching limbs before everything ended. Fuck. He really, really, just wanted to go home.
And when he finally did... Well, when he did everything washed away as he saw Katsuki humming to himself in the kitchen, dressed in nothing but the ridiculous apron Eijirou had bought him as a joke present a few birthdays ago. Okay, it looks like his limbs didn't hurt much anymore.
As Eijirou strode right into the kitchen, he made sure Katsuki knew he was approaching and had settled down every utensil. With no more waiting on his part, he quickly cupped Katsuki's bare ass and pressed their bodies so close he was sure Katsuki could already feel his growing arousal.
"Ah ah, not yet," Katsuki chided with a smirk that was met with Eijirou's pout. "You're gonna wash, then we're gonna eat, then..." he dragged his words to tease Eijirou even more. "Then I'm gonna ride you until you know nothing but how to scream my name, what do you think, my love?"
Eijirou had no time to reply, his head already turned into mush, that Katsuki finally turned his head to slot their lips together, still grinning at Eijirou's misery, the bastard.
The evening was hard in more than one sense. Especially when Katsuki kept walking nonchalantly as he swatted his naked hips. Especially when he kept teasing him about a fanfic he'd read that had given him quite the idea of what to do in the bedroom.
Eijirou was getting crazy. But not once he tried to touch Katsuki without his permission, not as much as a kiss that he wasn't sure his partner was 100% on board with.
Yet, he knew he'd be the one to turn that mischievous grin into the hottest disheveled expression, and that made the waiting a little more bearable. He was gonna have Katsuki ruined over him and he couldn't wait anymore.
Luckily, it seemed as Katsuki had just thought the same, deeming the time correct, taking him by the hand and hurrying him into their room.
It was going to be a loooong night.
—
Reading fanfictions to get ideas for new things to try had actually been such a breath of fresh air in their relationship, and Eijirou still chuckled thinking it all had been born thanks to Midoriya—not that he would ever tell Katsuki.
Well, it all came to an abrupt end during one tranquil night. They'd had the day all for themselves after two very strenuous weeks, and they couldn't wait to just bask in each other presence.
They were cuddling on the couch, as Katsuki's nails drew lazy circles on Eijirou's chest. Neither of them was really thinking about anything, but when Katsuki began absentmindedly playing with Eijirou's nipple, a moan set himself free from his throat.
"Ei?" Katsuki was chuckling and Eijirou stammered embarrassed. But the mood was there now and he wasn't gonna lose it. Nah ah.
He quickly enclosed Katsuki under him as he pressed a hard kiss on his lips before peppering his face and body with so many other pecks and small bites that Katsuki pretty much went limp with the sudden overstimulation.
"Babe? Everything alright?" Maybe he did go a little too limp and Eijirou had started getting nervous.
Soon, however, Katsuki snapped out of his daze and cupped Eijirou's face to drive their lips together in a silent 'yes'.
And Eijirou was gone again.
"Eiji..." After a few minutes of painfully slow kissing, Katsuki spoke. "Wanna try something new?"
And you know what? He did, he really did.
He nodded and soon rose from his previous position to go get his phone. Quickly finding the Dynamight|Bakugou Katsuki/Red Riot|Kirishima Eijirou tag, they began searching in the 'explicit' category.
After a few clicks, they found a fic which had a few kinks tagged they weren't too familiar with, but that didn't seem too weird—they'd read some things that had made them shudder from the simple thought far too many times already, and they always made sure to exclude them carefully.
As they sat comfortably with Katsuki's head slotted into Eijirou's neck, they began reading.
And that's when everything went south.
It has to be known that characterization hadn't been top notch for most fics most of the times, but it was normal considering everything was based on their hero personas, but still, the fanfics they read always portrayed them as a happy couple—maybe sometimes they were exes, or friends with benefits, and they'd use it for roleplay—but never they'd go near stories where one would hurt the other for the sake of sex. Not in an actual painful way, neither physically nor mentally.
Which was why Eijirou's breath hitched as he kept reading.
Katsuki had always been a fast reader, whereas Eijirou, because of his dyslexia, needed more time, which is why he always read it first and then waited for Katsuki as his pleasure started to build up in his chest.
Which is why, this time, instead of pleasure, it was an overwhelming dread that began clawing at his heart.
"Ei?" Katsuki's voice was somewhat distant despite the fact that there was less than a centimeter between his ear and Katsuki's mouth.
"Ei? Love? Can you hear me?" And oh, he was making Katsuki worry, maybe he really was that bad.
"EI." Katsuki's voice raised as he cupped Eijirou's cheeks to have him watch in the eye. "What is happening? Can you talk to me?"
Eijirou couldn't. Not after what he'd read.
He began trembling, his eyes welling up with tears. And oh, he'd just killed the mood. Why was he so bad?
Strong arms soon engulfed him, not a word spoken but in the language that was the steady rhythm of Katsuki's heart against his own.
It wasn't long before Katsuki found a way to get hold of the phone to scan over the fic. Eijirou didn't actually want him to read it, what if he found he agreed with it? He probably already did, he thought. But he had absolutely no strength to do anything, but keep sobbing silently into the embrace.
"What the actual fuck." Katsuki's words cut the air with nothing that couldn't be considered pure venom. "Who the fuck dares write such bullshit without even tagging it properly?" Katsuki was mad.
He quickly tossed the phone to the other side of the room and squeezed Eijirou even more.
"Eiji, my love, listen to me." A beat of silence. "The real me."
He took Eijirou's face between his hands and gave him a quick peck on the nose, and frowned when Eijirou couldn't find it in himself to even give him his usual wobbly smile. Fuck fuck fuck, he'd disappointed him again. No... please.
He was beginning to spiral.
"Eijirou." Katsuki was getting serious. "Ei."
"You are not a mutt. You are not a dog. And you're not less important than me in any way," he said trapping a tear with his thumb before it tumbled from his eye. "You're precious," he kept going as he linked their foreheads. "You're the most important and beautiful thing that has ever happened to me.
"You're not bad. You've never been bad, you've always been perfect." He sighed. "Even when we argue, even when you might make me mildly annoyed because you have forgotten to do some chores, you're always good for me. I'll walk barefoot on eggshells before I could even think about you in a negative light. And it doesn't matter that they played it out as some sexual fantasy. I would never get off you getting hurt or mistreated. Okay?"
Eijirou was trying to ease his breathing.
"Eijirou."
He looked at him.
"Answer me. You understand that I would never find pleasure in insulting you or making you think less of the literal god that you are?"
Eijirou gulped. Katsuki had always been very vocal with his praises for him, both in the bedroom and outside, but now he was really spilling his heart out, and Eijirou wasn't sure if he could actually accept them. Not when he'd just broken down for something like this.
"Eijirou. I'm not gonna back down. You're gonna answer me or you're gonna answer me." Katsuki's eyes were unwavering.
Eijirou assented.
"Good. And you know that you can always, always use the safeword, even if it were for just a kiss. And that I will always, always listen to it?"
Eijirou assented. It was the same for him, after all.
"Good."
Katsuki took a steadying breath and shifted their positions a little to have Eijirou sat completely on his lap, Katsuki's arms back to engulfing him.
He left a few quick kisses to his temple and cheeks, then began talking again.
"I understand if you want to back out for a while, reading that shit has been hard for me as well. Especially to think that there are people that call themselves fans of mine just to paint me as some kind of abusing monster..." He shuddered. "And I know how I was in the past, but if you'll still have me now..."
It was now Eijirou that noticed that sudden change in Katsuki. Shit, this had affected both of them, hadn't it? Eijirou still couldn't believe how Katsuki had been able to keep it steady for him until now. "Hey, Kat, babe, I never thought you were a monster, okay?"
Fuck, his eyes were glittering with unshed tears and he was absolutely gorgeous. Eijirou was so very gay and so very in love. Yep.
"It wasn't that that hurt me, I know you'd never lay a finger on me or treat me like literal garbage, or like a dog, or anything." He deepened their hug. "And yes, I will always have you, don't even think about the opposite, my love." He sighed. "I just got caught with past self worth issues, but I'm okay now, and it's all because of you."
Their gazes met again.
"Thank you, Katsuki. Thank you for being the best partner I could ever ask for, for being my best friend and being there for me even when something this stupid gets to me."
"Oi."
"Mh?"
"It's not stupid. It's not every day that someone reads about themselves getting treated like shit just to be said it's romantic. It's normal to feel bad about it."
Eijirou could feel his own resolution shake again. "Okay," he said. His eyes watering again.
"C'mere you handsome, gorgeous, perfect man, lemme see that smile that has my knees buckle and my mind become one tracked, will you?"
And, after he didn't even know how much time, finally, Eijirou smiled.
And, soon, Katsuki's own smile pressed onto his.
~fine~
