Chapter Text
"Ei."
Kirishima pauses his coffee making process to turn to his boyfriend, he knows that soft tone, knows it means Katsuki has something he needs to get off his chest.
"Yeah, babe?"
"Got some questions for you," Katsuki says absently, putting a pencil up to his lips.
"Okay?" Kirishima quickly turns to press the Brew button before settling in front of Katsuki, propping himself up on the counter on his elbows. "Fire away."
Katsuki doesn't look at him, but his cheeks turn a surprising shade of red. Kirishima frowns, racking his brain for what kind of questions Katsuki could possibly ask--
"How do you feel about cock torture?"
WHAT?!
"WHAT?" Kirishima chokes.
"Is that a no?" Katsuki asks, dragging his eyes away from his computer.
"YEAH KATSUKI THAT'S A NO. Holy fuck. what kinds of questions are these?"
"Don't be dumb, Eijirou. They're clearly sex questions. Pay attention."
Kirishima groans and rubs his hand on his face. "Some warning woulda been nice" he grumbles into his palm.
"Eijirou." Katsuki says completely deadpan. "I'm going to ask you some sex questions. Buckle the fuck in." He clicks his mouse. "Wax play?"
Kirishima's forehead thunks to the counter. "Yes," he whispers.
"I'm not going to ask about shit we've already discussed or done. Obviously bdsm, pet play, noncon fantasy, orgasm denial, piss pla-- you know when I say them out loud I realize you're a fucking deviant, Ei." Katsuki says with a smirk in his tone.
"Me?" Kirishima squeaks. "Some of those were your ideas!"
Kirishima is in love with the way Katsuki's mouth tips up in a grin. "But not all of them," he says.
"What about dp?"
Kirishima raises his face from the counter to met eyes with Katsuki. He's still embarrassed but... "Absolutely not."
"You must feel pretty fucking strongly to actually look at me right now. Why not?"
Anger sparks up Kirishima's spine at the question. "What do you mean why not?" It should be clear why not! He's NOT sharing. "Do YOU want to try dp?!"
Katsuki doesn't answer, his eyes flicking back down to the screen. "What about cucking?"
The anger in Kirishima spine, spreads up his skin, and slams his jaw closed. They're just questions. It's not Katsuki asking for these things. It's just questions. "No."
Katsuki raises an eyebrow. "Why not?"
Trying to calm himself down, Kirishima exhales through his teeth. It's stupid to get upset, and it's not like him either. It's just... Katsuki is his. Just his. He's not sharing. "You didn't ask me why not on the cock torture."
Katsuki lifts a shoulder in a shrug. "I don't particularly want to try cock torture. I've been thinking about these."
Absently Kiri registers the sound of the counter cracking under his hardened fingers. He releases his quirk and pushes away from the counter. Away from Katsuki.
He just needs to... breathe for a second.
He knows Katsuki would never expect the questions to upset him-- no one would. He's Kirishima Eijirou, literal ray of sunshine.
But fuck if the idea of Katsuki being touched by another person doesn't make him what to snap bones.
The knowledge that Katsuki has been THINKING about some random person (or worse one of their FRIENDS) intruding on THEIR romantic alone time is enough to make him scream. The anger is hot and consuming but under the anger is something worse. Something acidic and toxic. It wraps around his heart and constricts because this is it, this is Katsuki admitting that Kirishima isn't man enough to satisfy him and he wants someone else to try.
Because of course. Of course, Kat would realize sooner or later that there's probably better for him out there.
Sure, Kiri's dick is longer and thicker than average, and yeah, Katsuki has never complained (quite verbally the opposite) but maybe it's just facts Ei sucks at sex. Instinct tells him to do anything to save his relationship from crumbling-- and it'll probably crumble if Katsuki is unhappy sexually- but Kirishima knows he can't. He wouldn't be able to survive sharing Katsuki with someone. Or letting someone touch his boyfriend. Kiss him. Fu-
"Ei?"
Kirishima doesn't respond. Instead he shakes his head hard, like a wet dog, trying to dislodge the thoughts in his brain as he pours Katsuki a cupful of the coffee he just brewed.
"I'm gonna take a shower," he announces, turning the coffee pot on warm.
Katsuki frowns. "There's more questions. And you showered earlier."
He had showered earlier. "My shoulder still hurts from Tuesday. Hot water helps." Not a lie, his shoulder did ache a little.
"Fine." Katsuki stands up from the stool. "I'll come sit in there with you and we can knock some of these questions out while you shower."
Usually Kirishima liked it when Katsuki came in the room with him, liked when he talked through the steamy curtain. Today though...
"It's cool, Kat. Just drink your coffee." Hoping Katsuki understood his words for the dismissal they were, Kirishima heads toward the bathroom.
Kirishima manages to get into the bathroom, lock the door, get undressed and get under the hot spray of water before Katsuki breaks the lock and jerks the shower curtain open, making Kirishima scream like a little girl and cover his nipples. (He doesn't know why okay)
"You're pissed at me." Katsuki says, not at all impressed with Kirishima's scream. "Fuckin tell me why."
"You want to fuck someone else!" Kirishima instantly explodes, all the rage he feels, tumbling out of his mouth. "You want me to WATCH you fuck someone else! Jesus Christ, Bakugou!" Kirishima jerks the shower curtain out of Katsuki's hands just for something to do.
"How would YOU feel if I came home and suddenly announced, 'hey babe, sorry for this, but I think I want someone else to get me off because JUST YOU isn't doing it for me anymore!' Or 'It would be super manly for you to watch how good they wreck me that way you can see a good job'
Fuck. His voice had cracked there at the end. He had meant to stay strong.
"It’s fine." He adds hollowly. "I'm sorry I'm not enough for you or whatever."
It's not like he spent the last seven years in /bliss/, thanking the Gods for FINALLY winning Katsuki.
Shouldn't be that hard to give him up, right?
It was going to kill him.
When he finally looks at Katsuki, he sees the blonde is standing there, mouth open, eyebrows scrunched together in confusion.
"Ei... I'm not... I didn't mean to... Fucking offend you or whatever."
"It's fine," he says. Even though it's not. "You can't help how you feel."
Katsuki scratches a hand through his hair. "I'm confused. I've seen your porn history. You've watched double penetration. Hell, you've watched gangbangs."
Kirishima flushes red. "I like cum inflation! It's hard to see that with just one.... I don't... I'm... My porn preferences aren't on trial here!" He shouts indignantly.
"Well, neither are mine!" Katsuki shouts back.
"I'm not attacking your porn preferences, Katsuki!"
"No, you're just attacking my kinks! That's the same fucking thing, Eijirou!"
Kirishima's voice raises a few octaves, until, yep. He's yelling.
"OH MY BAD. WHAT SHOULD I HAVE SAID-- OH DAMN KATSUKI! THERE'S NOTHING I WANT MORE THAN TO WATCH SOME STRANGE GUY FUCK YOU! MAYBE I'LL LEARN A THING OR TWO AND YOU CAN FINALLY BE HAPPY WITH ME!"
Katsuki reels backwards, like Kirishima's words are a physical hit. "Eiji. Holy fuc--"
"I don't understand what it is," Kirishima continues, way too worked up to stop now. "I know my cock's big. Even if I was fucking /blind/, the way you talk about it would give me a clue. And you've never complained from dissatisfaction before. EVER. I make you cum EVERY TIME, before I cum. Usually twice! I eat you out CONSTANTLY. I'm happy too! I beg for it! I do whatever you want me to, unless we're in a scene, and then you don't really want me to do it." He opens his mouth for a breath to keep going. "I'm sorry if I'm not big enough. Or thick enough, or if I can't move my hips a certain way, or maybe I'm too heavy, or maybe I get too sweaty-"
A warm hand slaps over Kirishima's mouth. He sighs against it, inhaling.
"Eijirou. Holy fuck, Ei. Calm down for a second. Jesus." When Katsuki's sure Kirishima isn't going to start yelling out insecurity again, he pulls his hand away.
"Alright. Let's unpack this. First off, too sweaty? When we get done fucking there's a me-shaped sweat imprint in the bed. You literally almost slid off me once."
“Too heavy? That’s pussy-shit, Ei. I fuckin' ask you all the time to pin me down with unbreakable. I want you to fucking SUFFOCATE ME."
Katsuki reaches in and jerks the water of the shower off.
"Your cock is huge, you know that. I'm not gonna stroke your ego." He tosses a towel into Kirishima’s fumbling hands. "But just incase you don't know--" Katsuki grabs a handful of red hair and jerks Kirishima down until their noses are touching. "Your cock is massive. I seriously am afraid of it. Like a horny kind of afraid. Like you could tear me apart horny afraid. You move your hips PERFECTLY, asshole. You know this too. You fuckin'.." Kat's voice turns to a whisper, despite it being just them. Pressing their foreheads together he says, "you know you make me cry. That's not because you're bad at sex, Ei. It's because you blow my mind."
He snorts. "I AM happy with you. Idiot. Also... Fucking... damn it, Ei. You make me sound bad! It sounds like you're this sex god who gets me off fifty times and I do nothing to help you come! I owe you, alright? I'll fucking start making it up to you."
A smile teases Kirishima's lips. "You don't have to make anything up to me, Katsuki. You know I love having sex with you."
Fondly, Katsuki slides a hand up to cup Kirishima's cheek. "Good.." he says softly, before lightly slapping Kirishima's face. "So what the FUCK was that blow up for??"
Kirishima ducks his head, stepping out of the shower. His cheeks pinken a little as he admits, "If I'm so big and good at sex, then why do you want someone else to fuck you?"
At Kirishima’s words, Katsuki convulses, his tongue sticking out in a look of disgust. "FUCKING GROSS, EI." Kirishima watches in confusion as Katsuki actually gags, a full body shudder working through him. "I'd rather die than let some extra inside me. My ass is yours, and yours only."
That's... that doesn't make sense. Unless.. oh! Katsuki's confused! "I feel silly now. Kat, dp means two cocks. Inside you. Or me, I guess. GODS, DID YOU MEAN DP FOR ME?!? I DON'T WANT ANYONE ELS--"
"CHRIST, EIJIROU, NO! No! Fuck you! I'm not sharing you either!"
"You're not making any sense!" Kirishima whines.
Katsuki shoves at Eijirou's chest. "I wanted you and a toy! You fucking asshole. A SMALL toy, you massive-dicked himbo." He crosses his arms over his chest as he watches Eijirou redress. "A vibrating one, maybe."
Oh damn. That.. that made a ton of sense.
But wait. "What about the cucking."
They couldn't cuck with a toy.
Katsuki shuffles his feet. With his face flamed and his awkward shifting he reminds Kirishima of the first time they kissed back in high school. It's adorable. And his heart swells when Katsuki admits-- "I wanna... fucking... there's this clone quirk..."
"Oh! A clone quirk!" Instantly, like an excited puppy Kirishima shouts, "oh my GOD, COULD THEY MAKE TWO YOUS?! OR THREE?! OR FOUR? OR OH MY GOD FIV--"
"Eijirou," Katsuki says with a laugh. "No. It has to be you-- we both know I would kill all my clones for even looking at you."
"Plus, it's not like I can ask Ectoplasm or that villian from first year. And I want a clone that can handle some damage. Otherwise it'll dissipate the moment my explosions or nails or teeth puncture the thing." Katsuki pushes open the bathroom door. "I have a file."
While Kirishima dries his hair and shakes out like a wet animal, Katsuki pulls out the manila folder from in between the mattress. He turns to see Kirishima looking at him with wonder. "Shut up." He rumbles. "Don't give me that look. I just wanted to research her. That's it."
"Suuuuuurrrre, Katsuki." Kirishima teases. "It sure looks like you knew I'd say yes."
"WHAT THE FUCK EVER! ANYWAY," he opens the folder .”Her name is Ren Himoko. Her quirk is Displace."
"Displace?" Kirishima asks, hopping on his foot with a tilted head to get the water out of his ear. "That's not the general "Copy" or "Clones"
"Yeah," Katsuki says, sitting on the edge of the bed. "That's because her quirks different. She's not really cloning. She's... pulling."
"Pulling?"
Katsuki nods, the action barely noticeable. "She pulls a version of you from a different reality. It's still you. Just different. The reason I picked her is because her quirk lasts a whole day. And you can do whatever you want to the clone, it's REAL. Not a copy."
"An... alternate me? How does that work? Kirishima swallows. "What color is my hair going to be?"
Katsuki barks out a laugh. "THATS what you ask? Not "What if we aren't together in that version of my reality?"
Now it's Kirishima's turn to laugh. "That doesn't matter. Even if we aren't together in that reality, it's still ME, right? I promise EVERY version of me would gladly fuck you given the chance."
