It is apparently my turn to write my version of 'accidental nudes.'
Izuku buttdials Katsuki except it's a video call and he's undressing to shower, and Katsuki's life is promptly ruined.
==
MISCLICK
Katsuki was on his last set of push ups when his playlist abruptly cut off, replaced by his ringtone. He considered letting it go to voicemail because who the hell would choose to call if a text would do?
But then he spotted the picture of Izuku drooling in his sleep that Katsuki had assigned to his contact and paused in his reps to accept. The status 'connecting' appeared, which was when he realized it was a video call. That was weird.
Classes resumed tomorrow for their second trimester. What did the nerd need that couldn't wait until they saw each other in the morning?
Then the video connected. His steady exhale as he pushed up came out as a harsh wheeze instead. He remained frozen, not breathing, body held in an unintentional plank as he attempted to connect what he was seeing to his brain.
He recognized the bathroom in Inko's house–those light fixtures were still hideous–which meant that was absolutely Izuku's bare ass, perfectly framed within the 6-inch display of his phone screen. They were round and firm, flexing a little as he shifted to reveal a naked hip and the world-ending hint of green pubic hair. He appeared to be adjusting his clothes into a neat pile on the counter.
Then he turned away to slide open the glass shower door. Thanks to the wonders of modern technology, Izuku's phone camera captured in crystal clear detail the freckles dusting his pillowy buttcheeks, and the dimples at the base of his spine.
Katsuki's mouth was completely dry, and it was only the trembling of his arms that brought his attention back to the fact he'd been holding his pose for far too long. He collapsed to his stomach before rolling onto his back, his gaze never leaving the screen.
Shit. Shit?! It was obvious Izuku had called him by mistake. How in the hell Izuku had managed to accidentally video call him was anyone's guess, but he clearly didn't intend for Katsuki to see this.
Or did he?
No, no, the nerd had guts, but he'd never been this… brazen? Shameless? Wanton? That was such a weird word and not one he'd have ever used in relation to… well, anything.
He should hang up. Reach out and click that red little 'disconnect' button. Or he should speak up, yell at Izuku for being the most impossible person on the planet, and thoroughly embarrass him so that he would never make this mistake again. Because what if he had video called someone else? Like Uraraka? Or Todoroki?
Wow, Katsuki hadn't expected to hate that possibility.
While he was busy having a moral dilemma, Izuku had turned the shower on, one hand testing the water temperature. Katsuki did neither of the things he should have. Instead, he continued to watch, stomach in knots and heart in his throat, riveted by the sharp delineation of back muscles, the broad shoulders that narrowed to a trim waist and slim hips, and thighs that Katsuki may or may not have imagined wrapped around him at one point or another.
Then, Izuku moved again, stepping into the shower and flashing Katsuki a glimpse of his balls beneath the curve of his ridiculously perky ass before he slid the glass screen shut.
Katsuki was having an out of body experience. That had to be it.
The sound of running water, pounding into all that bare skin, splashing as Izuku soaped up his hair... The frosted glass stole away fine details, but the shape of him remained. His arms were raised, hands in his hair. Katsuki imagined those rough fingers working the shampoo into his curls, gently massaging his scalp in small circles.
The green blob of his head through the glass tipped back as he rinsed his hair. At this point, Katsuki had completely forgotten about his evening workout, and his racing pulse and the sweat beading his brow were from very different causes. He’d sat up, back resting against his bed while keeping his phone screen in view.
He was being disgusting. He shouldn’t be watching this. It didn’t matter that he’d seen Izuku naked countless times, at least peripherally because it was rude to stare, in the UA locker rooms. This was different. This was an invasion of privacy.
Jaw clenched tight, he picked up his phone with unsteady fingers, fully intending to hang up. Which was when a soft moan sounded through the speaker, barely audible above the running shower. Behind the glass, Izuku’s head was still tipped back, but his hand was moving in a way that was very hard to mistake as anything other than touching himself.
Katsuki fumbled the phone. He nearly dropped it, but recovered in time to see Izuku had paused and was now perfectly still behind the shower screen.
Oh, fuck. His fumbling must have caused some sort of noise or static, because Izuku began sliding open the shower door.
Panicked, Katsuki smashed his finger against the screen, ending the call just as large green eyes squinted in confusion directly into the camera.
At once, his playlist resumed, the loud music scraping at his raw nerves until he turned that off as well. Then it was silent, Katsuki’s quick breaths the only sound. What did he even do now?
He glared down at the erection tenting his shorts. He was so hard, he could practically feel the blood throbbing through his length. Cursing, he made to stand when a text lit up his phone screen.
>Izuku: Hey, did I call you by accident?
Katsuki was not prepared to deal with this so quickly. Gathering his resolve, he determined to ignore both the text and his hard-on.
Except another text arrived, along with a flurry of them in quick succession.
>Izuku: oh, it says video call
>Izuku: 16 minutes??
>Izuku: OMGJSRGBK
>Izuku: AAH I’M SO SORRY
>Izuku: I swear it was an accident! You didn’t see anything, did you?
>Izuku: Kacchan??
>Izuku: KACCHAN
>Izuku: I’M SORRY
>Izuku: this is so embarrassing
>Izuku: but if you think about it, we shower together after training all the time so no big deal
>Izuku: oh no
>Izuku: unless you saw something else?
>Izuku: aaaah so like
>“You have blocked this number. Report spam?”<
Katsuki did not mean to do that. Okay, no, he did, but not permanently. He just needed a moment to fucking think without Izuku’s yammering. Shit!
He paced, fingers flexing at his sides. What could he say? Yes, you called me by accident, and then I watched you touch yourself by accident. That would go over well.
With a frustrated growl, he flopped face first onto his bed. He had to fix this. How the fuck did he fix this?
His phone vibrated with another text. The hell?
>Half-and-Half: I’m not sure why he can't do it himself, but Midoriya wants you to call him
Katsuki rolled onto his back, scowling. The last thing he needed was anyone else getting drawn into this. At least it didn’t sound like Izuku had given him any details.
>>Me: no
The reply came a minute later.
>Half-and-Half: Midoriya says you’re being unreasonable. He didn’t explain, but I think he’s probably right.
>>Me: I don’t care what you think
>Half-and-Half: Did you two get into a fight?
>>Me: none of your business
Katsuki sent the text and then shut his phone off and tossed it onto the floor.
What the fuck just happened? What was wrong with him?!
Groaning, mortified, guilty as hell, Katsuki covered his face with both hands and wondered how he could possibly face Izuku tomorrow.
+++
The answer was he didn’t. Instead, he did everything in his power to ignore him.
When he’d entered the classroom that morning, seconds before Aizawa, Izuku’s face had turned a brilliant red. Then he’d tried talking to Katsuki during their lessons, his voice low and anxious, but Katsuki had ducked his head and pretended not to hear.
He was being an asshole. He knew that, but the alternative was admitting he’d watched Izuku undress, shower, and jack off for sixteen full minutes, which wasn’t a thing friends did—also not a thing easily explained away without some deeply awkward confessions—and fuck if he wanted to screw up their friendship with all his unnecessary feelings.
During lunch, he took his food into an empty classroom. Kirishima didn’t ask any questions but followed after him, because he was decent like that.
Before he could take his first bite, his phone began vibrating with an incoming call from an unknown number. Even though his stomach turned uneasily, he answered.
“Kacchan! Did you seriously block me!?”
Kirishima’s eyebrows shot up. “You blocked Midoriya?”
“Oh, hey, Kirishima-kun!" Izuku said, continuing to shout loudly enough that Kirishima had no trouble hearing him through the small ear speaker. “Kacchan! We need to talk about this. I’m not letting you stonewall me.”
“That’s pretty unmanly,” Kirishima said, super extremely unnecessarily.
Before he’d given his finger permission, Katsuki tapped ‘end call.’
Fuck.
“Bakugo!” Kirishima shouted, shooting to his feet. “Why would you—!?”
The phone started vibrating again, and before Katsuki could panic-push anything, Kirishima snatched the device from his sweaty grip.
"Midoriya?" Kirishima said into the phone. "I'm putting you on speaker."
"Thanks, Kirishima-kun. Kacchan, really? Unblock me so I can give Uraraka-san her phone back.”
From somewhere in the background, there was a giggle that Katsuki assumed was Uraraka and then a lower voice he recognized as Iida's muttering, 'This is extremely childish behavior.'
Oh yeah? Fuck off, Four Eyes. He applauded himself for not saying it out loud.
"Fine," Katsuki grumbled, holding out his hand for his phone.
Warily, Kirishima returned it, and with a few quick taps, Izuku was unblocked.
"There. Done."
"Okay. Gimme a sec."
The line went silent, indicating Izuku had hung up. Katsuki made a strangled sound like a muffled scream before covering his face with both hands.
"Sooo, what was that all about?" Kirishima asked carefully.
"Fuck off," he mumbled through his fingers.
Before Kirishima could say anything else, his phone began vibrating for a third time. He glared down at Izuku's contact name and photo.
Taking that as his cue, Kirishima picked up his tray and tossed a quick, "Whatever’s going on with you two, I know you'll work it out," over his shoulder. Then he left Katsuki alone with his spiraling thoughts, offering a supportive thumb's up in parting.
Sighing heavily, Katsuki answered the call.
"Kacchan," came Izuku's voice, more tentative than before.
His stomach instantly cramped with guilt. The nerd sounded genuinely hurt. An angry Izuku he could deal with–anger was an old comrade, after all. But a sad Izuku with big watery eyes and slumped shoulders and that tension of pain when he spoke? Katsuki could do nothing except fold.
"Are you really that disgusted with me?" Izuku asked in a small voice.
"I'm not disgusted with you," Katsuki snapped. "I'm… fuck, Izuku. I'm disgusted with myself."
"What? Why? I'm the one who sent you a video call while… w-while doing that…"
That being what Katsuki had been unable to banish from his mind's eye for longer than a handful of minutes all day–Izuku's plush ass that begged to be squeezed, the corded muscles in his thighs, that devastating flash of his balls, and the soft sounds of his pleasure as he touched himself. For what felt like the hundredth time today, he forced himself to imagine unsexy thoughts instead because he was not getting a boner at school, damnit.
"The fuck you mean why? You did it by accident." While I continued watching on purpose.
"But it made you so uncomfortable. I know I said we need to talk about this, but…I won't make you if you really don't want to. If you'd rather we just… forget it happened, I swear I'll never bring it up ever again."
What if I don't want that? What if I want it to happen again? "Izuku, what the hell is wrong with you? You should be pissed with me."
"I am!" Izuku shouted with a huff. "Because you blocked me! After everything we've been through, you freaking blocked me! It was an accident, and I was so embarrassed that I fantasized about changing my name and moving to Hokkaido, and instead of being just a little bit understanding, you blocked me!"
Wincing, Katsuki offered lamely, "It wasn't forever."
"That's not the point. I thought I was–" There was a wet sniffle, which only made the blade of guilt twist deeper into Katsuki's gut. "I thought I was going to lose you again. Over something so stupid."
Katsuki shoved his untouched lunch tray onto the neighboring desk so that he could drop his forehead onto his own with a dull thud. He was such an asshole.
"Don't have to worry about that, nerd. Not gonna happen. Listen… I'm sorry, all right? I didn’t exactly think it through, but it was still shitty of me."
"It’s okay. You overreacted," Izuku said. "And then I overreacted. Can I, um, ask why?"
"Why did I overreact?"
Izuku gave a small hum of confirmation.
"Are you really gonna make me say it?"
"You blocked me, and then hung up on me!"
Katsuki's face went hot. "Yeah, okay, fine." He fought the urge to hang up on him again. "Fuck. Sixteen minutes, Izuku. I shouldn't have…Why the hell are you not pissed at me about that?"
The ensuing silence lasted so long that Katsuki had to check to see if the call dropped. It hadn't, and a moment later, Izuku drew a loud breath, like he was preparing himself for something.
"Well, why… why didn't you end the call?"
Trust Izuku to ask the one question Katsuki had been running from. "I didn't want to."
"What does that mean?"
Katsuki squeezed his eyes shut, swore long and loud, and then finally just blurted, "Because I answered your call and got an eyeful of your naked ass, and I didn't want to stop. Seeing it. You. Whatever."
"Oh."
Katsuki snorted at the bewildered tone. "Yeah. Oh."
"Kacchan… Kacchan liked seeing me like that?" Even through the phone, Katsuki could tell Izuku was blushing hard enough to risk fainting.
"I will fucking block you again."
"I'm not teasing you! Why would you want to see me, um…"
"Fuck's sake, just say it. You were naked. Bare-assed, balls out, dick swinging–"
"Kacchan!"
With a mean laugh, Katsuki took pity on him. At least he wasn't about to implode from mortification any longer, although he still had to come clean about why he hadn't simply ended the video call.
But first– "How do you even manage to make an accidental video call?"
"O-oh, well, th-that's… I was just… trying to put on music."
Eyes narrowed, Katsuki asked, "And you didn't realize there wasn't any music playing?"
"Well, no, because I changed my mind."
"Uh huh. What aren't you telling me?"
"This isn't about me! Stop trying to turn the tables on me."
"I'm not telling you a damn thing until you explain how you managed to video call me your naked ass."
He bit back a chuckle when Izuku made a miserable, high-pitched noise.
"I was just scrolling through your texts, that's all. And then I misclicked when I closed out of it."
Sitting upright, Katsuki pulled up their chat history. Aside from Izuku's texts from yesterday, the last thing they'd talked about was not slacking off during break. Because Izuku had sent him a picture of his deep-fried dinner, and Katsuki had sent a sweaty gym pic in response. A sweaty gym pic in which he'd taken off his t-shirt to drape around his neck.
A terrible grin stretched his mouth.
“Oi, Deku.” There was no hiding the humor in his voice. “You sure you didn’t call me on purpose?”
“I didn’t! It was an accident!”
Katsuki wasn’t sure he believed him, but that was fine. He slouched in the chair, kicking up his legs to rest on the desktop. He’d been so stressed about what Izuku would think, that he would draw the obvious connections and realize how Katsuki felt, but maybe he’d gotten it wrong.
The nerd was taking Katsuki’s confession surprisingly well. Suspiciously well, in fact. It was possible Izuku was keeping his freak out contained until he was alone—that was the kind of annoyingly considerate thing he’d do if he was worried about Katsuki blocking him again.
Except knowing he’d been looking at their text history before he then jerked off in the shower, and the flustered, almost panicked, edge to his voice that couldn’t be faked… Katsuki felt unexpectedly lighter than he had in… maybe ever.
“What if I said I did?” he asked softly, because it was still weird saying it out loud.
“Did?” Izuku asked, clearly trying to recover the trail of their conversation.
“Like it. Seeing you like that.”
There was a long, tense silence. Then, sounding breathless, Izuku murmured, “I-I… liked it, too. Because it’s Kacchan.”
Fuck. So much for not getting a boner at school. Well, Katsuki was nothing if not committed once he made a choice. “Would you let me look again? On purpose?”
His answer was a whispered exhale: “Yes.”
Katsuki dropped his head back, unable to stifle a groan as he pressed the heel of his palm to the front of his uniform trousers. How was this happening? It didn’t feel real. Another out of body experience like when he’d watched Izuku touch himself in the shower. Or a hallucination born from years of suppressing how he felt.
Except Izuku really had video called him, even if by accident, and he really had just admitted liking Katsuki’s eyes on him.
“Kacchan,” came Izuku’s shaky voice. “You’re not messing with me, right? This isn’t just to get back at me for what happened?”
“Why the fuck would I?” He was insulted that Izuku would even think that of him.
“I don’t know,” Izuku said, and Katsuki hated how small he sounded. “I didn’t think Kacchan would ever look at me that way.”
Katsuki couldn’t judge, considering he’d assumed the same. They were fucking idiots. But they were also pretty damn good at making up for lost time.
“Did you think about me when you were touching yourself in the shower?” he asked, surprised by how steady he sounded.
Izuku swallowed audibly. “…Yes.”
Switching off speaker mode, he put the phone to his ear and closed his eyes. He couldn’t risk anyone potentially overhearing and barging in only to find him with his hand on his dick. He’d be on house arrest for a month.
“It was the gym pic, huh? You do that often?” He slowly rolled his hips against his hand, easily recalling Izuku’s silhouette through frosted glass, head tipped back and hand working himself.
“I… I always imagine it’s you.”
His voice was so quiet, Katsuki half wondered if he’d imagined the words. He gripped his thickening length through his trousers, seeking more friction.
“You doing it now?”
“What? No! I’m in a bathroom stall. Anyone could come in.”
He groaned. “So what? I’m in an empty classroom.”
“You’re in a… Kacchan!” He had the nerve to sound scandalized. “Are you t-touching yourself?!” His voice pitched up at the end, which made Katsuki snort.
“Not anymore,” he grumbled. “You fucking ruined it.” Exasperated, he gave his dick one last squeeze and then straightened in his seat.
“Wait… Were you trying to have phone sex?”
Katsuki hung up on him.
+++
He ignored Izuku for the rest of the school day, but the air of desperation—for reconciliation—was gone. Which was fine because neither of them could look each other in the eye. Even Izuku seemed too humiliated to do much more than hide his red face behind his hands.
Ignoring Kirishima’s questioning glances, Katsuki hurriedly changed into his sports uniform for after school training. Most of their classmates had headed back to the dorm, so the locker room was nearly empty when his phone vibrated with an incoming text.
He pulled on his top, leaving it unzipped as he opened the text without checking the name. It was probably one of the extras asking for help with homework.
It was not. Katsuki’s eyes widened at the text before frantically shoving the phone into his pocket and looking around to check if anyone had noticed. The only other person in the room was Sero, who was folding his trousers to tuck into his locker.
Pulse racing, stomach in knots, Katsuki grinded his teeth and waited until Sero left. The moment the door shut after him, Katsuki whipped out his phone again.
For the second time in as many days, Izuku’s bare ass took up his phone screen. Although he hadn’t included his head, Katsuki knew that arrangement of freckles over smooth skin. Izuku’s back was turned, the picture taken in front of his bathroom mirror with his uniform top gathered high around his chest. He was completely naked from the waist down.
Since the video call, Katsuki had guiltily wished once or twice that he’d taken a screenshot. Now, the perky globes of Izuku’s asscheeks were bared for him, along with those thick thighs and the delicious dip of his spine. His incredible legs were pressed together so even though his butt was perfectly displayed, Katsuki couldn’t actually see his hole or anything else.
He was almost instantly hard, so suddenly turned on that he felt lightheaded from the whiplash. Where did Izuku get the fucking balls to send this after barely being able to look at him in class?
Storming off towards the toilet stalls, he locked himself inside one of them before furiously responding to the unsolicited ass pic.
>>Me: WHAT THE FUCK IZUKU?!?!?!!!!!
The dots that indicated he was typing appeared immediately. Ridiculous nerd was probably anxiously waiting for his reaction.
>Izuku: um… I felt bad about leaving you hanging earlier?
>>Me: how was this your solution???
>Izuku: I don’t know! seemed like a good idea
>Izuku: you said you liked looking at me
>Izuku: are you mad?
>>Me: of course not! just surprised
>Izuku: oh
>Izuku: good surprised or bad surprised
Before he could talk himself out of it, he gripped his erection through the front of his uniform pants and snapped a pic. Then he sent it off along with a short text:
>>Me: what do you think?
He squeezed himself, trying to steady his breaths as he watched the dots appear and disappear a half dozen times. As he waited, he banged the back of his head against the stall door, wondering what the hell he was doing.
His phone finally vibrated. Later, he would be embarrassed by how he scrambled to open the text.
Izuku had sent another picture, and the moment he saw it, he couldn’t stop the groan that climbed up through his chest.
“Shit,” he hissed, rubbing himself through his pants. “Shit, shit, shit.”
In the photo, Izuku was still in front of his mirror, but he’d taken a side shot. So not only did he get a stunning view of that bubble butt in profile but also his flushed cock, hard and thick, damp head leaking over his fingers wrapped around the length.
Katsuki bit down on his lower lip, mouth watering at the sight. He’d figured himself out early on, especially after realizing he didn’t share his friends’ interest in girls and sex. He didn’t spend much time thinking about dicks either, but never before had he wanted to taste one as badly as he did now.
Izuku was the only person he would kneel for, and fuck did he want to kneel for him.
He realized he’d been staring at the photo for far too long when another text popped up.
>Izuku: Kacchan?
>>Me: what are you doing to me, Izuku
>Izuku: whatever you want
>Izuku: when will you be done with training?
>Izuku: wait, is that too fast?
>Izuku: it’s just I’ve wanted you for so long
>Izuku: oh god don’t answer that
>Izuku: I’m ruining it again, aren’t I
>Izuku: sorry I’ve never done this before >_<
Despite that he was unbearably hard, Katsuki laughed. Damn sexy, adorable dork.
>>Me: no shit
>Izuku: :(
>Izuku: I’m not sending you any more pics
>>Me: the hell you ain’t. stay where you are, nerd. I’ll be right there
