HAPPY BIRTHDAY @notrishno
#HappyBirthdayTrish2020
Collab w/ @RinjiAfterDark!

I was struck with inspiration from a rather hilarious source, and I couldn't resist making an au out of it for you ;D I hope you enjoy!

Eijirou hates math.

It takes a lot to make Eijirou hate 𝙖𝙣𝙮𝙩𝙝𝙞𝙣𝙜, but math??

Pure unadulterated hatred.

All of the equations and shapes and formulas are blending together on the page for him, and he’s come so close to falling asleep and drooling all over his homework so many times that he’s stuffed a napkin in his mouth to chew on just to keep himself awake.

𝙉𝙤𝙣𝙚 𝙤𝙛 𝙩𝙝𝙞𝙨 𝙚𝙫𝙚𝙣 𝙢𝙖𝙠𝙚𝙨 𝙨𝙚𝙣𝙨𝙚…

It takes him another six rereads before he lets his head drop against the desk, his quirk absorbing the impact with a loud thunk.

Math should 𝙣𝙤𝙩 be this hard. His eyes flicker up to the wall in front of him— the wall that separates his room from Katsuki’s, his best friend and tutor.

And his likely unrequited crush, but Eijirou tries not to think about that.

He slowly sits back up with an exasperated huff, grabbing his phone and pulling up his text conversation with Katsuki. If anyone can help him through this bullshit, it’s him.

He catches him early enough that he’s not asleep yet, thankfully, and Eijirou’s heart soars when he gets a quick reply.

It seems to take a while for the actual pictures to come through, long enough for Eijirou to nearly nod off again.

His eyes actually slip closed for a sweet, blissful moment, before he’s awakened by a series of pings from his phone.

He sighs softly and taps the notification, scrolling up through the pages of notes...

𝙐𝙣𝙩𝙞𝙡 𝙨𝙤𝙢𝙚𝙩𝙝𝙞𝙣𝙜 𝙩𝙝𝙖𝙩 𝙞𝙨 𝙖𝙗𝙨𝙤𝙡𝙪𝙩𝙚𝙡𝙮 𝙣𝙤𝙩 𝙣𝙤𝙩𝙚𝙨 𝙘𝙪𝙩𝙨 𝙩𝙝𝙧𝙤𝙪𝙜𝙝 𝙩𝙝𝙚 𝙥𝙖𝙜𝙚𝙨 𝙤𝙛 𝙛𝙤𝙧𝙢𝙪𝙡𝙖𝙨.

Hardening ripples up Eijirou’s whole body, shooting across his face and down his arms, crushing his phone in his palm and effectively destroying the photo on screen.

He must be dreaming, right?

This is a very, very elaborate dream, because there’s no way 𝙆𝙖𝙩𝙨𝙪𝙠𝙞 𝘽𝙖𝙠𝙪𝙜𝙤𝙪 just sent him a Nude Photo of his chest wrapped tight in fishnet lingerie.

𝙀𝙭𝙘𝙚𝙥𝙩 𝙩𝙝𝙖𝙩 𝙝𝙚 𝙙𝙞𝙙 𝙖𝙣𝙙 𝙤𝙝 𝙜𝙤𝙙 𝙖𝙡𝙡 𝙤𝙛 𝙩𝙝𝙚 𝙗𝙡𝙤𝙤𝙙 𝙞𝙣 𝙝𝙞𝙨 𝙗𝙤𝙙𝙮 𝙞𝙨 𝙧𝙪𝙨𝙝𝙞𝙣𝙜 𝙨𝙤𝙪𝙩𝙝 𝙩𝙤 𝙛𝙞𝙡𝙡 𝙝𝙞𝙨 𝙘𝙤𝙘𝙠.

The picture’s gone but the image has forever been burned into his eyelids—𝙩𝙝𝙤𝙨𝙚 𝙜𝙤𝙧𝙜𝙚𝙤𝙪𝙨, 𝙥𝙞𝙚𝙧𝙘𝙚𝙙 𝙥𝙞𝙣𝙠 𝙣𝙞𝙥𝙥𝙡𝙚𝙨—

His thoughts are thankfully disturbed by a sudden yell and crash against the wall in Katsuki’s room. 𝙃𝙚 𝙢𝙪𝙨𝙩’𝙫𝙚 𝙟𝙪𝙨𝙩 𝙧𝙚𝙖𝙡𝙞𝙯𝙚𝙙 𝙩𝙤𝙤...

𝗦𝗵𝗶𝘁.

Eijirou’s ruined phone clatters to the wooden surface of his desk in a rain of shrapnel and glass, abandoned in favor of sprinting over to Katsuki’s room, exhaustion forgotten.

So what if his shoulder slams into his doorframe in his haste?

The throb shooting up and down his arm’s got nothing on the one pulsing through his cock right now.

Katsuki just sent him a nude of his tits...

Katsuki just sent him a nude of his tits 𝙄𝙉 𝙇𝙄𝙉𝙂𝙀𝙍𝙄𝙀.

He’d always wondered what Katsuki thought about that sort of thing.

He was never very outspoken about his opinions on sex, even though Denki, Mina and Hanta talked about it enough.

Sure, he had gotten his nipples pierced at the beginning of this year, but that didn’t necessarily mean anything sexual.

He wasn’t even sure if Katsuki was attracted to men until Mina had mentioned it to him.

And after that one time she called Midoriya on the very same thing, only for Eijirou to catch him sneaking into the kitchen at 3am dressed in nothing but a button-up shirt that clearly belonged to one (1) Shouto Todoroki with all the alternating damp patches and scorch marks?

Yeah, no, Eijirou had learned the very important lesson of never doubting Mina’s nose when it came to sniffing out sexual desire in their classmates.

If she was hinting at Katsuki, then clearly she was noticing 𝙨𝙤𝙢𝙚𝙩𝙝𝙞𝙣𝙜...

Eijirou raps his hardened knuckles against Katsuki’s door, his other hand reaching down to turn the knob and push the door open.

He wasn’t sure what he was expecting, honestly. A fist in the jaw. In the gut maybe. Explicit cursing and yelling in his ear, for sure.

But Katuski’s just… Sitting on his bed.

Staring at him in a mix of mortification and anger that has his face flushing bright over the bridge of his nose and up to his ears.

He’d absolutely kill Eijirou for thinking it, but he looks adorable right now, and he can’t help his sheepish grin as the door closes behind him.

“So… Lingerie, huh?”

“You know what? I was gonna let you live but I changed my mind, get the fuck over here Shitty Hair!”

Katsuki’s embarrassed snap only makes Eijirou laugh, and he’s quick to cross the room, entirely unafraid of the threat of death and flopping down to sit next to his best friend.

“Oh come on Bakubro, you look good in fishnet!” Eijirou just can’t help himself, the tease flies out before he can stop it, and then he’s laughing when Katsuki jumps on him and tries to smother him with a pillow.

“I will literally murder you, asshole!” He’s flushed so red, from the tips of his ears down his neck and his collarbone and shoulders beneath his tank top. 𝙋𝙧𝙚𝙩𝙩𝙮...

“Hey come on, you know I’m kidding! I wouldn’t actually make fun of you for that, Bakugou.”

Eijirou’s laughter eases up a bit when Katsuki’s half-hearted attempts on his life slow to an eventual stop.

Eijirou moves the pillow aside, eliminating the only thing shielding their bodies from each other.

From here, Katsuki’s tank hangs off his body enough that Eijirou catches peeks of sheer fishnet from the straps running over his shoulders.

Katsuki goes quiet at that. His jaw is clenched, cheeks burning, eyes locked onto Eijirou and searching for anything even slightly disingenuous about those words.

But he knows he won’t find it.

Eijirou has been the one consistently honest and genuine thing in his life up to this point, and right now is no different.

Attempts at making him swallow a pillow aside, he feels pinned by those sweet, non judgmental eyes.

𝙃𝙚 𝙝𝙖𝙩𝙚𝙨 𝙝𝙤𝙬 𝙙𝙞𝙨𝙖𝙧𝙢𝙞𝙣𝙜 𝙩𝙝𝙚𝙮 𝙖𝙧𝙚.

“Hey.” That voice goes just as soft as his gaze, and Katsuki knows he’s 𝙛𝙪𝙘𝙠𝙚𝙙, jerking his eyes away from the sight that makes his stomach twist in the way he should hate but 𝙘𝙖𝙣’𝙩 because it’s 𝙀𝙞𝙟𝙞𝙧𝙤𝙪.

“What?” Quiet, raw; nothing like the bantery yelling from a bit ago.

“I’m bein’ serious for a sec here.” A hand reaches up to lay against Katsuki’s warm cheek, turning his face back toward Eijirou’s own.

“Was it just an accident..?”

Katsuki takes a second, lips parting before closing and opening again. Eijirou’s never seen Katsuki hesitate like this, never witnessed him fishing for the right thing to say.

Whenever Katsuki speaks, he speaks fast, and with confidence.

Something pulls tight inside his belly; sadness maybe, or anxiety?

If it all was just an accident, and Katsuki didn’t want anything from Eijirou other than for him to put it out of his mind and forget it ever happened, Eijirou would do it.

He’d do it, and he’d try to bury his feelings for his best friend along with the picture.

It’ll be hard, he won’t lie to himself.

He’s been nursing these feelings since they met; and now as third-years, Eijirou’s become more and more certain that they won’t be able to just fade away anymore.

Maybe there was never a point where they could’ve.

They rage and burn inside, like a forest fire— like the explosive hero himself.

Guess he shouldn’t be surprised that he was engulfed in Katsuki’s blaze so long ago.

“You can just say it. It’s okay. I’ll forget all about it, if that’s what you want.”

Eijirou’s calloused thumb rubs across Katsuki’s cheekbone, and his heart jumps when he feels Katsuki lean into his touch.

“Shut up, idiot. I never said that.”

All the bite in his words is gone; Eijirou’s never seen his eyes look so unsure, so open.

And his heart pounds in his chest as Katsuki meets his gaze and holds it, furrowed brow doing nothing to hide the vulnerability suddenly present in those cardinal red eyes.

“Yeah, okay? It was a fuckin’ accident.” He admits quietly, voice sounding rough around the words. “But…”

“But... I don’t really mind that it went to you, okay?”

He tries at the end to sound huffy, really he does. Eijirou can tell.

But those eyes put out an emotion that overwhelms the tone of his voice, and Eijirou’s heart is racing when he guides Katsuki down into the kiss he was already subtly leaning into.

He doesn’t pull him in, doesn’t rush him; just meets him in the middle once he’s close enough with a gentle press of his lips.

That’s something else he’s always wondered about Katsuki too;

how he would kiss.

Eijirou always figured he’d be aggressive with it, the way he is in every other aspect. He had expected teeth, bites, a bloodied lip if things got really heated.

But this…

This kiss is 𝙣𝙤𝙩 that.

While it lacks ferocity, Eijirou feels the steady, determined press of Katsuki’s mouth against his. He’s softly devouring him, easing him into parting his lips to let Katsuki take what he wants, and Eijirou moans when that happens to be his tongue.

His heart’s beating so hard against his ribs and he’s like, 98% positive that Katsuki can hear it, but he’s too busy falling apart under his best friend to care about that.

𝙊𝙝 𝙢𝙮 𝙜𝙤𝙙 𝙝𝙚’𝙨 𝙜𝙤𝙤𝙙 𝙖𝙩 𝙩𝙝𝙞𝙨 𝙬𝙝𝙖𝙩 𝙩𝙝𝙚 𝙛𝙪𝙘𝙠—

Katsuki pulls up from the kiss, staring down at Eijirou with that self confident smirk that makes his head spin, and his cheeks go as red as his hair when Katsuki licks his lips nice and slow.

“That all you got? That was just a kiss Shitty Hair, 𝙬𝙝𝙖𝙩’𝙧𝙚 𝙮𝙤𝙪 𝙜𝙤𝙣𝙣𝙖 𝙙𝙤 𝙬𝙝𝙚𝙣 𝙮𝙤𝙪 𝙨𝙚𝙚 𝙖𝙡𝙡 𝙤𝙛 𝙢𝙮 𝙡𝙞𝙣𝙜𝙚𝙧𝙞𝙚, 𝙝𝙪𝙝?”

Eijirou.exe has stopped working.

He stares up at Katsuki in a mix of shock and 𝙝𝙤𝙧𝙣𝙮, jaw dropped and mouth gaping as he tries to form a semi-intelligent response to that.

He’s suddenly hyper aware of their positions; Katsuki on his elbows and knees above him, arms caging him against the bed and a knee digging into the bed between Eijirou’s thighs—𝙥𝙧𝙚𝙘𝙖𝙧𝙞𝙤𝙪𝙨𝙡𝙮 𝙘𝙡𝙤𝙨𝙚 𝙩𝙤 𝙝𝙞𝙨 𝙨𝙚𝙢𝙞.

As usual though, his mouth takes the lead before his brain has a chance to stop him.

“Rip it off of you, probably.”

His cheeks blaze with heat, but the shocked expression Katsuki’s face morphs into deeply satisfies something primal in him, and Eijirou pushes up onto his own elbows, closing the distance between them for another sweltering kiss.

Katsuki’s shock seems to wear off quickly too, if the arms thrown around his neck and the blunt teeth digging into his bottom lip mean anything at all.

“The fuck are you waiting for then? An invitation?”

Technically speaking, yes. Eijirou is. And Katsuki’s taunt is just the one he needs.

He pushes up, grabbing Katsuki’s arms and flipping their positions around, trapping him against the bed now as he dives in for more heated kisses.

Kissing Katsuki is so addictive, Eijirou just can’t get enough.

𝙉𝙤𝙬 the teeth are coming out, and Eijirou grunts when Katsuki snatches his bottom lip between his teeth and tugs, looking up at him with the exact same smirk from that photo—

𝙏𝙝𝙚 𝙉𝙪𝙙𝙚.

Eijirou’s attention immediately drops down to Katsuki’s chest. Katsuki’s tank is twisted up around his torso from all the movement; putting one of those fishnet clad tits on full fucking display for him.

His head drops down to lave his tongue over said tit, tongue dragging hot and long right over his pierced nipple.

“Fuck! Fuck fuck— What d’you think you’re 𝙙𝙤𝙞𝙣𝙜— 𝘼𝙖𝙖𝙝𝙝𝙝 𝙨𝙝𝙞𝙩!”

Katsuki’s moans are like music to him. The closest he’s ever heard to him making sounds like these have been from well-timed blows on the battlefield. But even then, hearing those sounds from pain holds no candle at all to when they come from pleasure.

Eijirou almost feels like he can get drunk on those too.

Fingers thread through Eijirou’s messy hair as his tongue continues to smother his nipple with attention.

Ever since getting the piercings, Katsuki’s been more sensitive to being touched here, even just from clothes.

Eijirou’s caught him putting covers on them for combat training in the locker rooms.

At the time he wasn’t sure what they were for, but now as he crouches over Katsuki, suckling and biting around Katsuki’s perky nipple while he writhes and cries out his name, he understands.

He’s sure to give the same attention to the other as well, fingers sliding up to replace his mouth on one when he switches to the other.

𝘾𝙤𝙪𝙡𝙙 𝙆𝙖𝙩𝙨𝙪𝙠𝙞 𝙘𝙪𝙢 𝙟𝙪𝙨𝙩 𝙛𝙧𝙤𝙢 𝙩𝙝𝙞𝙨?

He sure sounds like he could, with the way he’s moaning and bucking his hips in search of friction just to find nothing.

Eijirou’s carefully avoiding Katsuki’s crotch, eager to test his theory out now.

Leaning all of his weight on his right leg Eijirou shifts the left down to trap Katsuki’s thighs against the bed.

He slides down onto his elbows, arms caging Katsuki in on either side of his heaving chest so he can get in closer to his tits.

“H-Hey, why th’ fuck did you stop??”

Katsuki’s head lifts from the bed to make eye contact with Eijirou, cheeks going red when instead of giving an explanation, Eijirou curls his fingers around the edges of the netted bra and pulls them down, the material gathering beneath Katsuki’s plump pecs to push them up.

It makes them look even fuller, if it were possible, and Eijirou salivates at the sight.

“Did you think you could show me how slutty you were being in your pretty lingerie and expect me not to do anything about it?”

Eijirou bites back at him with a grin, dropping down to swirl his tongue around Katsuki’s nipple, holding his gaze all the while.

“Oh fuck— Oh fucking shit, Ki-Kirishi𝙢𝙖𝙖𝙖—!”

Katsuki’s eyes go hazy from the rush of pleasure Eijirou can practically feel vibrating up his spine, and he moans out low and breathy now that nothing’s separating Eijirou’s tongue from his bare skin.

His fingers work Katsuki’s unoccupied nipple, thumb sweeping over the hard nub and fingers lightly flicking the piercing.

“FUCK! Aga-Again!”

Eijirou’s cock gives a heavy twitch in his shorts at the straight-up whine Katsuki lets out when he does that, and he can’t help but sink his teeth straight into Katsuki’s tit, tongue and fingers relentlessly playing with his nipples as his cries get louder.

“𝙀𝙞-𝙀𝙞𝙟𝙞-𝙧𝙤𝙪! 𝙁𝙪𝙘𝙠! 𝙁𝙪𝙘𝙠! 𝙒-𝙒𝙖𝙞𝙩, 𝙬𝙖𝙞𝙩 𝙄 𝙘𝙖𝙣’𝙩— 𝙄’𝙢 𝙜𝙤𝙣𝙣𝙖—!!”

His thrusting hips grow more and more desperate, until Katsuki’s pulling on Eijirou’s hair hard enough to rip some of the bright red strands out and arching up into a shivering orgasm, Eijirou’s name on his lips as he blows his load in his own sweats.

Eijirou’s moaning around Katsuki’s nipple the whole time he watches him explode in pleasure like that.

It’s almost enough to make him cum too, but he just barely hangs on to a thread of self-control he scrambled to find in the last second.

He’s gentle when he dislodges his teeth from Katsuki’s pec, sweetly lapping up the blood a few of his teeth drew from the plump flesh.

“I-I think that’s the hottest thing I’ve ever seen in my life..”

Eijirou’s voice trembles a little as he leans up to press a kiss to Katsuki’s lips, swallowing up a few harsh pants as he tries to catch his breath beneath him.

“J-Jerk.. Going after.. Where I’m most.. Sensitive..”

Katsuki huffs, trying to pull his brain back into his skull and batting Eijirou’s shoulder with a playful smack when the redhead only laughs and kisses him again.

“Yeah yeah, laugh it up now, I’m comin’ for you once I can move again, Shitty Hair.”

Katsuki shifts a little bit, grimacing when he feels the sticky mess he made of himself.

“Hey, get this shit off me, will ya?”

He lifts his hips to allow Eijirou to slide off his sweats, eyes going wide at the mess Katsuki made of his matching 𝙛𝙞𝙨𝙝𝙣𝙚𝙩 𝙛𝙪𝙘𝙠𝙞𝙣𝙜 𝙥𝙖𝙣𝙩𝙞𝙚𝙨.

They’re soaked, utterly dripping with Katsuki’s cum and smearing the mess across his inner thighs as he shifts on the bed again.

“Looks like you already 𝙙𝙞𝙙 come for me, Bakubabe.”

Eijirou grins impishly at him as he tosses the dirtied sweats to the floor, taking immense joy from the blissed out little glare Katsuki levels him with.

“I should gag that smart mouth of yours.” He threatens, not at all expecting the way Eijirou’s pupils dilate.

“I mean, I wouldn’t say no.”

Katsuki blinks at him, and Eijirou just blinks right back; both stunned speechless for a second before Katsuki sits up on his elbows a bit.

“Are you serious?”

“I mean..” Eijirou’s cheeks flush and he reaches up to rub at the back of his neck. “I trust you with my life, y’know? So I’ll trust you with anything in here, too. Besides, I… 𝙠𝙞𝙣𝙙𝙤𝙛𝙖𝙡𝙧𝙚𝙖𝙙𝙮𝙝𝙖𝙫𝙚𝙤𝙣𝙚??”

..............................

It takes Katsuki’s orgasm-fuzzy brain to decipher that one, but when he does, that grin is back full force, and he’s dragging Eijirou down into a messy, tongue-filled, open-mouthed kiss.

“Go get it then. And anything else you have. Because we won’t be done until the sun rises, got it?”

”𝙊𝙝 𝙛𝙪𝙘𝙠 𝙮𝙚𝙨.”

~~~~

Well, they didn’t quite make it until sunrise, but 4:24am is pretty damn close.

By the time they’re finished with each other, the 5th, 4th, and 3rd floors have all fled to the commons for refuge in the form of a giant sleepover style cuddle pile in a massive pillow fort,

escaping from the screams and moans of pleasure that Katsuki’s dorm room just couldn’t stifle.

There’s a hole in the wall, the bedsheets are singed in some parts and shredded in the others, except for one spot where the burns seem to overlap through the slices where Eijirou pinned Katsuki’s hand through one of his many orgasms.

Katsuki’s lingerie is ruined from hardened claws and Eijirou’s second favorite jockstrap is in tatters somewhere on the floor, mixed in with the filthy toys and emptied lube bottles.

There’s a lamp on the floor too, and the curtains are half yanked off the sliding glass doors, letting moonlight stream across Eijirou and Katsuki’s intertwined bodies where they lay, blissed out amidst all the lust-wrought destruction.

Eijirou’s arms drape snug around Katsuki’s finger-bruised, bitten up hips, drawing him in close so that he can feel the other’s warmth as he begins to drift, the fatigue from before finally catching up with him.

“I’m so in love with you..” Eijirou sighs into messy ash blonde spikes, still breathless and running on fumes of energy.

“Took you long enough to say so, Shitty Hair.” He can feel the puff of air from Katsuki’s snorted laugh against his collarbone, and his smile stretches wider.

“Yeah.. True. But I said it. And I mean it, Katsuki.” He leans down, catching Katsuki’s lips in yet another sweet kiss that makes his heart jump when Katsuki leans right back into it.

“Good.” Katsuki dips back in for another peck, true red meeting crimson.

“Because I love you too, Eijirou.”

~END~

Holy shit this was fun to write xD Imma just gently set this right here
