An Aro to the Heart [NSFW]
Added 2025-06-20 09:00:03 +0000 UTC“Seriously? Another one?”
Uraraka cracked a smile, and Izuku knew he was turning pink – he hadn’t expected the words to actually slip out, he’d expected them to just stay in his head. Then again, that seemed to happen to him a lot, so he really shouldn’t have been surprised.
“Getting jealous?” Uraraka teased, nudging him lightly. “You could always just ask him.”
“Yeah right,” Izuku snorted. “I don’t even know where to start with that.”
“Personally, I’d start with he’s hot and clearly you’re jealous of his... extra-curricular activities.”
“I’m not jealous.”
“Sure, buddy.”
Izuku huffed, but he gave up on arguing; she wasn’t... entirely wrong. It wasn’t like he wanted to go around and fuck all of their classmates, be in a different dorm room every night or whatever. And he wasn’t that surprised, either; Kacchan was hot, by far the best-looking guy in their class. Izuku was just a little surprised that he had any interest in sex, that was all. Kacchan had always seemed so laser-focused on his career, Izuku had never expected him to start... casual sexing? Was there a word for it? Was that what sleeping around meant? He really wasn’t well enough educated on the subject to be able to talk about it properly, he’d always been more focused on his career, too. Honestly, though, he was pretty sure if he called it Kacchaning his classmates would all know exactly what he was talking about.
So no, he wouldn’t say he was jealous. But there was something in him, something he couldn’t quite put words to, and it pretty much boiled down to one thing: why had Kacchan never asked him if he wanted to have sex? They were best friends, weren’t they? It had taken a lot of work to get there, but they’d ended up so close again, over the years. Surely, if you wanted to screw around or experiment with someone, you went to your best friend, right? Especially when said best friend was openly queer, it just seemed like the logical choice to make!
He was still fuming about it when he sat down in the sparring gym to wait, glancing at the time on his phone – no doubt Kacchan would end up late, after his stupid, middle-of-the day... romp.
He scrolled through his social media apps while he waited, catching up on the few posts people had made in the last few days, and when the door slid open, he barely looked up, unable to resist giving Kacchan a sideways look.
“What crawled up your ass?” Kacchan asked, rolling his eyes.
“Nothing,” Izuku answered, a little sharper than he’d intended. “Just waiting.”
“For me?” Kacchan raised an eyebrow. “I’m early.”
Izuku glanced at his phone, cursing under his breath. Technically, even if it was only by two minutes, Kacchan wasn’t wrong. Damn it.
“Thought maybe you’d be too busy,” Izuku said scathingly.
Kacchan didn’t respond, and Izuku busied himself with putting away his phone, climbing off his seat to get started. When he looked back, though, he found a conceited smirk waiting on Kacchan’s face, and immediately knew he was doomed.
“What, you jealous?” Kacchan asked, barely containing his amusement. “Did I fuck your crush or something?”
“Kacchan! What the hell?!”
“Or what, you’re pent up and don’t have the guts to ask anyone? Our classmates are horny as fuck, they’ll go for it.”
“Stop.”
“Oh, I get it, it’s because of your huge-ass crush on me,” Kacchan sneered. “Not like you’ve been subtle about it for, what, fifteen fuckin’ years?”
Izuku felt the annoyance bubbling inside him, his face burning with anger instead of embarrassment for once, as something inside him snapped.
“I do not have a crush on you,” he argued. “Why would I? You’re a self-centred asshole half of the time, you’re a dick to all of our classmates, everyone thinks I’m insane for even considering you my friend with the way you talk to me most days, and yet somehow, they’re the ones you went to, when you wanted to screw around?! God, for someone so hot, you’re so fucking dense.”
Kacchan just stared at him, one eyebrow raised, betraying the curiosity Izuku had apparently piqued in him.
“And that’s not supposed to sound like a fuckin’ crush?”
“No! It’s not like I’m doodling your initials in my notebooks, or daydreaming about holding your hand, or some stupid shit like that! I’m not allowed to think my best friend is hot?!”
“Obviously I am,” Kacchan snorted. “It’s not that part I’m asking about.”
Kacchan sat down, jerking his head toward the chair Izuku had just vacated, but Izuku was still feeling bitter, choosing to just fold his arms over his chest and glare at him instead.
“Sex is fun,” Kacchan told him, surprisingly quietly considering Izuku’s mood. “But I have no interest in being in a relationship or anything like that.”
“So what?” Izuku huffed.
“So I figured you’d only want to sleep with someone you were dating.”
Izuku blinked, his anger settling back down to a simmer; Kacchan was being... considerate?
“Why would I want to date you?” Izuku asked. “You seem like you’d be a nightmare to date.”
“Didn’t want to make things weird, if we wanted different shit,” Kacchan clarified, ignoring the slight. “It took us a while to get here, don’t need to fuck it all up again.”
“Oh.” Izuku deflated, his anger vanishing.
Kacchan nodded at the seat next to him again, and this time, Izuku caved. He fell into the chair heavily, the legs scraping loudly on the floor.
“I know you’re queer,” Kacchan began. “But I don’t know how you are with... the more obscure labels, I guess.”
Oh.
“You’re Aro,” Izuku said quietly.
“Yeah,” Kacchan agreed, even though it hadn’t really been a question. “But not everyone gets that.”
“So... you don’t think you’ll ever date anyone?”
“I doubt it. I guess it could change, but the idea of... sharing my life. I don’t like that.”
“Never having any real alone time,” Izuku said softly. “Sharing your home, letting someone see all the weird, private parts of your life, always having to share your bed.”
“Yeah,” Kacchan chuckled. “You know me well.”
“No, I...” Izuku trailed off, his mouth weirdly dry. “Me too, maybe.”
“Oh.”
“I can’t imagine it,” Izuku explained. “Not any time soon, at least. Maybe it’ll change, like you said, but... I don’t see it.”
The room fell silent, and Izuku jumped when a shoulder bumped into him, Kacchan leaning over with a little smirk on his face, just to nudge him.
“Well?” he asked. “You gonna say it, or are you waiting for me to do it?”
“Say what?”
Kacchan just looked at him, and Izuku’s blush clearly came from embarrassment, this time.
“Do you want to screw around or not?” Kacchan asked. “But I swear to god, if you fall in love after all this shit and make it weird...”
“Why would I fall in love with you?” Izuku asked, leaning away and pulling a face. “You’re an asshole.”
Kacchan laughed brightly, and Izuku finally cracked a tiny smile, reaching out to shove him.
“We’re here to spar.”
“We can do that any day,” Kacchan pointed out. “How often do we have a room to ourselves?”
“There’s not even a bed in here.”
“You think we need a bed to fuck?”
“We probably need lube or something.”
“Fair,” Kacchan conceded, standing up from his chair and moving to stand in front of Izuku instead. “Maybe another time, then.”
Izuku felt a weird disappointment well up inside of him – apparently some part of him had been hoping Kacchan would have a solution, after all his... experience.
A foot nudged at his leg, and Izuku could only watch in confusion as Kacchan shoved his knees apart, crouching down to reach for Izuku’s waistband.
“W-What are you...?”
“Just because we can’t fuck doesn’t we can’t screw around,” Kacchan said. “What, you don’t want to?”
“I do.”
“Damn right.”
Kacchan stripped the leggings and underwear off him, tossing them aside with zero care, and Izuku could only watch, dumbfounded, as Kacchan knelt down between his thighs. He paused for a moment, glancing up at Izuku to make sure he was cool with it, and honestly? Izuku was pretty sure that was the hottest thing he’d ever seen. Kacchan, such a gorgeous man already, on his knees, hot hand spread across Izuku’s thigh, looking up at Izuku with his face full of... something. Something Izuku couldn’t put a name to. It was soft, open, caring, but also hungry, and Izuku wasn’t surprised he’d hooked up with so many of their classmates, after seeing that face.
“Do it,” he said breathlessly.
He couldn’t tear his gaze away, as he waited for those warm fingers to move, to wrap around his suddenly aching dick. But Kacchan’s hand stayed on his thigh, holding his legs apart, his eyes dropping from Izuku’s as he ducked his head.
Fuck.
Kacchan’s lips were soft, and wet, and apparently this was not the first time he’d opened them for a guy, because he didn’t even hesitate, wrapping them around Izuku’s shaft and swiping his tongue across the tip to make Izuku whine.
He had not been expecting that.
When Kacchan began to move, to slowly shift in and swallow him down, Izuku lifted a hand to his own mouth, biting down on his knuckles to keep his moans at bay. Kacchan slapped his arm away, not giving him a chance to properly stifle it. The sounds that came out were mortifying, Izuku was sure he’d never stop being embarrassed, and he knew Kacchan would never let him live it down, but his body wasn’t exactly giving him a lot of choice in the matter.
Kacchan’s free hand slid up under Izuku’s shirt, curling around his hip bone, and his pace sped up, bobbing his head like a god-damn expert. Izuku reached for him, tangling his fingers in Kacchan’s soft hair, and Kacchan growled quietly in warning. Izuku gasped, the vibrations going straight through his cock, and while he wasn’t entirely sure, he was fairly certain that he saw Kacchan roll his eyes. He tightened his grip, pulling Kacchan’s hair gently, and Kacchan didn’t stop him – somehow that was almost hotter than the mouth on his dick.
The hand left his thigh, and Izuku looked down to see Kacchan shoving it down his pants. He jerked himself off roughly, still sucking Izuku’s dick as he worked, and Izuku wished he had enough flexibility to get in there and help him out, without missing out on his own stimulation. He’d have to pay him back another time, he supposed. That was probably a good thing anyway, to be fair – he needed to do a little research before he tried anything out for real.
For now, though, all he could do was twist his leg a little, tilting his foot inward and pressing it to Kacchan’s crotch. The hand stilled, and Izuku slid his foot up, putting a little more pressure on as it stroked Kacchan through his pants.
Kacchan’s pace faltered, and Izuku spared a glance down at him, ready to pull his foot away, until he saw the look on Kacchan’s face – he wasn’t sure he’d ever seen Kacchan look so... blissful. His eyes were a little glazed, his perfect lips still stretched wide around Izuku as he tried valiantly to keep moving steadily, his other hand dead still in his pants, as he leaned into Izuku’s touch.
Well then.
He pressed a little harder, slowly sliding his foot up and down Kacchan’s shaft through his clothing, his baggy sweatpants doing absolutely nothing to hide how hard he clearly was. Kacchan shuddered, then slowly began to lean in again, eyes falling closed. Izuku moved his foot a little quicker the next time, and Kacchan mimicked his pace, keeping time with Izuku’s motions.
Fuck that was hot.
He pulled a little harder on Kacchan’s hair, dragging him in a little quicker, and Kacchan moaned around him, all deep and satisfied. It was no wonder all their classmates wanted a piece of him, if he sounded like that in the bedroom. He could feel himself getting close, so he did his best to bring Kacchan there too, with what little coordination he could manage with his awkwardly angled foot. Kacchan didn’t seem too fussy, in all honesty, about coordination and consistency – he seemed more than happy exactly where he was.
When Kacchan’s eyes fluttered open again, peering up at Izuku with such a dazed look in them, he knew he was out of time. He pulled Kacchan’s head in close, feeling him swallow awkwardly around Izuku, and then Izuku was coming, shooting everything straight down Kacchan’s throat. Kacchan didn’t gag, even once, and Izuku was pretty sure that would have set him off all over again, if he wasn’t already so spent.
A damp patch in Kacchan’s pants told him that whatever it was he’d done in those last moments, it had done the job for Kacchan too. There was a clear damp patch, the fabric darker when Izuku glanced down, his dick a lot less prominent against Izuku’s touch.
Kacchan swallowed again, and Izuku hissed quietly, releasing Kacchan’s hair and letting him sit back on his knees. Izuku’s dick fell soft and heavy between his thighs, and his face turned red again – even after all of that, having Kacchan’s eyes right at eye level with his limp dick was not exactly an experience that filled him with confidence.
“Creep,” Kacchan said, a little fondly, as he adjusted his pants. “The foot, really?”
“You’re the one who got off on it.”
Kacchan pouted, looking away sheepishly, and Izuku finally managed to crack a smile.
“Alright, you pass,” he said, standing up and hunting for his clothing to make himself decent – had Kacchan really needed to throw them so far?
“I pass?” Kacchan demanded.
“Yeah! No love, but super hot, so we’re definitely doing this again.”
“Oh, we are, are we?” Kacchan asked, clearly a little amused. “Maybe I only fuck each person once, you ever think about that?”
“Well you haven’t fucked me yet, so,” Izuku began pointedly, scooping up his backpack from beside the chairs. “And then I get to fuck you too, so that’s a third meet-up. And my room is right below Kaminari’s, so I know for a fact that you fuck people more than once.”
“We’re that loud?”
“You’re so loud,” Izuku told him, unable to resist a laugh. “So, now it’s my turn. Clean yourself up so people don’t ask questions – actually, you know what, they don’t need to ask. It’s you.”
“Shut up.”
“I have lube in my room,” he continued. “And it’s almost time for Kaminari’s nightly guitar practice.”
“So?”
“So I’m gonna make sure he hears you over it.” Izuku grinned, extra widely when he saw Kacchan’s expression. “What, you like that?”
“Fuck off,” Kacchan said, averting his eyes quickly, though the bulge in his sweatpants said everything Izuku needed to know. “Fine, but you better not fall in love when you learn how damn good I am in bed.”
Izuku snorted, and Kacchan managed a little smile of his own, as he finally got to his feet to follow.
“Poor Kaminari is gonna be so lonely, after tonight,” Izuku couldn’t help but tease. “You’re never gonna go back to those extras again, after having my dick.”
“Not gonna lie, hearing you call them extras is kinda hot,” Kacchan teased right back. “Gonna have to be a real good fucking, if you think you can beat the rest of them.”
“Plus fucking ultra.”
