“Izuku.” Katsuki said the nerd’s name like he was surprised even though he knew it was going to be him at the door. There were only two people who ever knocked on Katsuki’s door unannounced and Eijirou was out of town on a mission.
“Hi Kacchan! Can I come in?”
“Does it matter if I say no?” Katsuki grumbled under his breath as he stepped back from the door, opening it wider. It’s not that he didn’t like having Izuku over, but it had been getting increasingly harder to deal with the feelings that bubbled up when the other man was around.
Whatever had been going on during the war had settled into a friendship, but Katsuki desperately wanted more. The problem was he’d tried asking for more a few times and he couldn’t get a clear read on Deku either way.
One day he was rejecting Katsuki’s offer to join him at his agency and the next he was asking to sleep over because he’d found a spider in his apartment. They had grown out of sharing a bed, but still…it wasn’t meaningless that he was the one Izuku would come to for support when he was scared.
It also didn’t help that Deku somehow managed to keep getting cuter and sexier and more bite-able all at the same time. Katsuki had no choice but check out his ass as he bent over to untie the laces of his shoes. His leggings were already tight enough without the extra pressure, but it showed off exactly how stacked he was.
Since Katsuki couldn’t bring himself to look away, he closed his eyes and waited until he heard the shuffling of socked feet against hardwood floor. He followed Izuku towards the couch, but before he could ask what brought the nerd over, the theme to the All Might Golden Age anniversary special started playing.
“Sorry,” Izuku said. “I gotta take this.”
“Hey, ‘Toshi! What’s up?”
Katsuki hated that damn nickname. He should be the only one Izuku had a cute name for. Though to be fair, he was the only one who got ‘chan’, so he was willing to take the win.
“Uhuhh.” Izuku was frowning and since Katsuki couldn’t make out what the other man was saying, he could only hope it wasn’t too serious.
“Yeah, I’m totally fine doing later in the day.”
“Up to you.”
“Okay, great—thanks for fixing it!”
“Alright, see you Sunday!”
Izuku hung up the phone and Katsuki asked, “What was that about?”
“Oh, umm…Hitoshi and I are doing a day trip to do a wine tasting this weekend and the vineyard had to cancel our tour slot so he was just calling to figure out the logistics
“Are you dating?” Katsuki blurted out before he could stop himself.
Izuku gave him an unreadable look that brought back all the insecurities Katsuki felt right after the war, when he didn’t know where the two of them stood in relation to each other. The next word out of Izuku’s mouth was, “No?” but it sounded more like a question that a statement and Katsuki’s heart choked. “Is that a question or a statement?”
“No, we’re not dating.”
“You’re going on a date with him though?”
“No.”
Had Katsuki missed something? “Then what’s up with the wine tour and tasting?”
“We both loved this vineyard’s wine when we had it at a local bar so when we found out the winery was only a couple hours out of town, Toshi suggested we go visit.”
“You may not be dating him, but I think he might be dating you.”
“It’s not like that.”
“Next you’ll be telling me you haven’t been going on dates at all. That you haven’t been dating Pink Cheeks or that Icy Hot Bastard either.”
“What?! No!”
“Okay so from your perspective, what’s the explanation for you and Pink Cheeks being all over the tabloids at the opening night of that skyscraper restaurant? Or the social media posts of the handmade pair of mugs IcyHot gave you?”
“Well, the restaurant is right by where Ochako lives and one of her friends is a chef there so she was invited for the opening and took me. And Shoto has been working hard learning to make pottery and when he gifted me some stuff from his new collection, I wanted to show support for him and help spread the word about his business.”
“On Christmas?”
“It was a holiday collection!”
“What I’m hearing is that you heard nothing when I told you that if you treat everyone like they are special, it makes no-one special.”
“I heard you! And I’ve taken that advice.”
“By dating people and then insisting you’re not dating them?”
“I’m not. It’s like you said: my closest friends are special so I’m treating them like they’re special.”
“From what I’ve seen treating them like they’re special looks a whole lot like dating them. So I’m not one of your close friends then? If acting like you’re dating someone is the measure, I must not count.”
Katsuki knew he was being petty, but now he’d put the pieces together, his heart had started to crack. Not that he’d even be able to handle going on dates with Izuku and keeping it straight that that meant they were friends, but the implication of not getting that treatment…
“I thought we’d fixed things,” Katsuki said.
“We did!”
“Then why are you going on dates with all your friends and not me.” Well fuck, now he was just straight up pouting.
“Because you’re not just a friend!”
All the hits he’d taken on the job, all the times he’d been laid out flat, all the times he’d landed himself in the hospital and nothing hurt like like those words. “You don’t consider me a friend?”
“That’s not what I said.”
Katsuki’s brain was was a jumble of disconnected thoughts and scrambled emotions. He felt like he had missed something, but wasn’t sure quite what. And then Izuku was looking at him the same way he’d look at a bird with a broken wing and Katsuki’s hurt began spinning into rage. Didn’t Izuku know by now he hated to be looked down on?!
Katsuki started gathering the words to express his anger, but before he could get them out, Izuku said words Katsuki never thought he’d hear in his sweet voice, “I love you.”
“What?!” All the fight drained out of Katsuki because, what?!?!
“I can’t treat you like all my other friends because it would be too confusing. I’m trying to live my own life. Not always following you around. Isn’t that what you wanted?”
One gut punch after another. “I haven’t wanted that for a long time.” Katsuki stumbled over the words, not sure how to express himself but also…did Izuku mean it the way Katsuki so desperately wanted him to? “And when you say you love me, is that like how you love everyone special in your life…or…”
“You’re different.” Izuku’s voice was just above a whisper. “You don’t have to say it. I get that it’s not like that for you. I—”
“Shut up. I don’t have to say what? How much clearer could I have been than asking you to join my hero agency and be by my side? Can you never just say what you mean? Let me show you.”
“Kacchan you don’t have—”
“I fucking died for you and you think I’m afraid of words. I love you, Izuku. I love you so much it consumes me. I love you so much I don’t just deal with the emotional rollercoaster you put me on, I relish in it. I wake up and thank the gods I don’t believe in that you’re alive and by my side then curse them for not bringing you closer. You think I’d do this for anyone else?”
“You mean it? You really do… love me?”
Izuku’s eyes were so hopeful, it reminded Katsuki of a much younger Izuku, before the war, before school, before things had gone wrong between them at all. It was everything Katsuki wanted for Izuku to see a hopeful future by his side. He locked his gaze with Izuku’s and as earnestly as he could, he said, “I really do love you.”
Izuku sniffled and the shine in his eyes turned wet. “And… would you, um, wanna date me?”
“I don’t know how to date because I’ve never wanted to be with anyone but you. And you don’t know either if the way you hang out with your friends is any indication, but yeah, I do.”
A tear escaped from Izuku’s right eye and Katsuki reached his thumb out to wipe it away before it reached the cluster of freckles on the apple of his cheek.
“Aww, crybaby.”
“‘M just so happy.”
Katsuki could see the truth of it in the strain of his smile across his cheeks.
“Can I kiss you?”
Izuku nodded, sending tears streaking down his face as Katsuki leaned in. Their first kiss was soft, tentative and atop Izuku’s plush lips, Katsuki could taste the salt of his tears.
They kissed again and pulled back to smile at each other with dopey grins. Everything was perfect until Izuku’s lip began quivering again, but this time there was something off about the impending tears.
“What is it?” Katsuki asked. Whatever it was, he wanted to fix it.
Izuku’s chin tipped down and his eyes slid down to his crotch. For a split second Katsuki delighted in the thought he might have found Izuku hard. He followed Izuku’s eyes down to find…nothing?
He was about to vocalize that, but before he could, he saw the fabric at Izuku’s crotch darkening. It wouldn’t have been the first time Izuku had an accident on his couch but Katsuki knew how upset he’d get about it it later, so he sprung into action, pulling Izuku into his arms and then lowering them both to the floor.
“This is so embarrassing,” Izuku said through fat tears. He had tried to hide his shame by crossing his legs, but his bladder was too full. Already, the wetness had spread to his mid thighs and a small puddle was beginning to form underneath his ass.
“You’re saying that like I haven’t known you all your life.” Katsuki snorted. When Izuku got overwhelmed, so did his bladder. Katsuki had watched it happen when they played together as kids, at family dinners, on patrol, during training, at the mall…you name it. The nerd had gotten better at hiding his little accidents, but Katsuki, let’s say, had developed a particular interest in watching the nerd wet himself over the years.
“Aww, cute little pissbaby, c’mere.” Katsuki held out his arms, but when Izuku made no move to come closer to him. Katsuki decided to scoop him into his lap.
“Kacchan, wait! I’m not done!”
Perfect. Katsuki smiled as Izuku continued to protest. The puddle where Izuku was sitting was sizable, about as big as one of Katsuki’s gauntlets and as promised, he was still letting out more, the warmth of his piss seeping into Katsuki’s lap.
“Kacchan, please.” Izuku’s voice wobbled with the promise of tears. “I’m getting it all over you!”
“Relax nerd. It’s not like I didn’t see you were wetting yourself when I decided to have you in my lap. I don’t care if I get a little wet.” In fact, Katsuki cared a lot. He wanted more of Izuku’s piss on him…but they could get to that confession in a bit.
Katsuki buried his face in Izuku’s neck, kissing at the tender flesh there and breathing in his scent. This was heaven. Izuku wanted him and was pissing on him and if Katsuki’s hardening cock had anything to say about it, they were definitely going to be having sex very soon.
Izuku’s accident subsided and the nerd had the audacity to try and leave.
“Where do you think you’re going?” Katsuki asked, squeezing him tighter.
“To clean up?”
“Nuh-uh. You’re deluded if think you’re going anywhere before I’m done with you.”
“You mean…” Izuku’s face tinged pink to finish his sentence.
“I mean, I really want to have sex with you as soon as humanly possible.”
“Really? You want to? Even though I had an accident? After I wet myself?”
“I especially want to after you wet yourself. My piss kink didn’t develop out of thin air.”
Izuku’s eyes did the thing they always did when he was trying to figure something out and Katsuki waited patiently for him to understand. He wasn’t proud of it, but the bullying wouldn’t have gone as far as it did if he hadn’t picked up the bad habit of jerking it to images of Izuku with a hand between his legs trying and failing to stop the wetness from dripping down his inner thighs.
Understanding made it’s way into Izuku’s eyes and now it was Katsuki’s turn to be embarrassed. He offered a weak “sorry,” as he pulled his bottom lip between his teeth.
“Since middle school?” Izuku asked.
Katsuki winced, then nodded.
“Me too. I mean not every time, but there were times I sort of found it arousing when you made me lose control like that.”
The idea of it lit a fire in Katsuki. Izuku hobbling home with wet pants to jerk it to the idea of Katsuki bullying him…or better yet, just doing it in the forest while Katsuki was rushing home to take care of himself. “Wanna make you lose control control all sorts of ways,” Katsuki said, pressing his hips up to make sure Izuku was fully aware of his painfully erect cock.
“Please,” Izuku groaned, spreading his knees apart to show off his own erection.
“Please what?” Katsuki asked, even though he was already removing Izuku’s shirt.
“Please…ummm…” Izuku trailed off as Katsuki undid the zipper of his pants, peeling the wet fabric away.
“I’m waiting…” Katsuki teased as he palmed over Izuku’s erection through the cold wet fabric of his boxers. His cock jumped as he felt the warmth of a small spurt escape Izuku’s tip, even through his hardness.
“Pleasefuckme!” The words blended together, but it was enough for Katsuki to keep going.
Izuku was a vision splayed out naked on Katsuki’s floor. The flush of his cheeks spread down to his muscular chest though it was hard to focus when Katsuki was discovering for the first time that his cock had a slight curve to it. Izuku had asked to be fucked and Katsuki fully intended to give the nerd what he wanted, but next time…next time he couldn’t wait to feel what that curve could do to him.
Katsuki undressed with an efficiency he hadn’t known he could muster, then covered Izuku’s body with his own, kissing up his neck and into his hair as his hands greedily groped wherever they could reach. He felt an eagerness he hadn’t felt since the first time he’d had sex, overwhelmed by exactly how much he wanted this.
“Kacchan,” Izuku whined. “Please. Need you inside.”
And how could Katsuki resist. “Yeah, okay, I’ll go get some lube.” He tried to pull away, but Izuku locked his ankles behind Katsuki’s back, keeping him in place.
“You don’t need to. I’ve got a plug in. And it’s super wet inside. You can just—” Izuku pulled one knee to his chest and Katsuki sat back on his heels to confirm that yeah, Izuku was, in fact, wearing a plug. A black one. With an orange X across it. One that Katsuki thought was ridiculous when it was pitched by his marketing lead. But now…she was definitely getting a unexpected bonus.
“For me?” Katsuki asked.
Izuku nodded and Katsuki began to toy with it, gently pressing it in and out.
“I always wear a plug when I come visit. So I can get a dildo in faster when I get home.”
Katsuki’s breath hitched. “Is that a common occurrence? You come home from visiting me and wanna fuck yourself.”
“Mmmhmmm.”
“Anyone else you do that shit for? You got a whole collection of hero-themed buttplugs? One for every classmate.”
“I collect them all, but I only wear Kacchan’s.”
“So you did hear what I said about treating people special?”
“Did it before.”
“Before? Since when?”
“Since it came out. I—” Izuku’s breath hitched as Katsuki tugged at his rim with the plug. “I have all the Dynamight-themed sex toys.”
“You know they took a cast of my cock.”
“Yeah, but they scaled it down, didn’t they? To make it accessible to a wider audience? It’s at the top of the range of the standard line of sex toys the collab company—” Izuku was cut off again by Katsuki pushing the plug in.
“You’re such a nerd knowing about my scaled down sex toy. Now…you wanna stop rambling and have a taste of the real thing?”
“Yes, yes yes yes,” Izuku chanted.
The plug slipped out just as easily as Katsuki slipped himself in. As promised, Izuku’s channel was wet. He started off with slow, experimental thrusts, coating himself in the wetness and letting Izuku adjust.
“You don’t have to go slow. I like it to be intense,” Izuku said. “Hard and fast, just on the edge of painful.”
“Anything you want. Wanna fuck you so good you piss yourself again.” Katsuki was almost embarrassed to admit it, but Izuku seemed to have taken his earlier confession in stride so he didn’t hesitate to vocalize this particular fantasy as he picked up the pace.
Katsuki set a punishing rhythm, snapping his hips as hard and deep as he could. Next time he’d see about bending Izuku over a table and taking him from behind, to give him even more force.
Izuku cried out beneath him and Katsuki was sure it had only been a minute before Izuku was calling out that he was getting close. Katsuki smiled, silently thankful Izuku was also about to burst because he didn’t stand a chance now that he was actually fucking the man.
Izuku’s ass clenched around Katsuki as he came, pushing Katsuki over the edge with him. As their bodies tensed and relaxed, Katsuki kept his eyes on Izuku’s face. This was what he wanted. To make the nerd see stars like this every day for the rest of his life.
Katsuki knew Izuku was too sturdy to be crushed but he couldn’t help but want to be careful with him so instead of letting his body collapse, he lowered himself to his elbows so they could enjoy maximum skin contact without the pressure of his weight.
A moment or two later, he felt a warmth against his stomach and his cock spasmed at the knowledge that he had, in fact, fucked Izuku so well that he was pissing himself.
“It...ummm…”
Katsuki shut Izuku up with a kiss because how could anyone be this perfect.
Katsuki sent Izuku ahead of him to the shower so he could clean up the mess they had made on the living room floor. When he arrived, he found Izuku with three fingers up his ass. Katsuki fucked him again, then pissed inside of him since the next thing he planned to do was clean out Izuku’s ass.
Suffice to say their shower was anything but efficient and by the time that Katsuki was picking out an oversized shirt for Izuku to sleep in, they were both thoroughly exhausted.
As they snuggled up in bed together, it occurred to Katsuki that the whole evening had been off the rails. “I’m not complaining about how things went, but was there a reason you came over in the first place?”
“There was a spider in my kitchen. And I got scared. And you’re the only one that knows.”
Something squeezed in Katsuki’s chest because dating his friends or not, how could he have possibly doubted that he was special to Izuku? “The war hero and respected UA teacher Izuku Midoriya is scared of itsy bitsy little spiders?”
“Don’t tease. You know I can’t coexist with them!”
“Aww, baby. I know. They’re scary for you.” And Katsuki was the only one to know it so he would be the only one who could fix it. “You don’t ever have to go back to your place ever again. Move in with me and I’ll protect you.”
“My hero.”
“Is that a yes?”
“Of course, Kacchan. I love you.”
“Love you too, nerd.”
