Okay hear me out. Katsuki with late onset Masaru genes, right?

Like he doesn’t need glasses until his third year at UA, and by this point he’s been squinting at shit for a month now, so all it takes is one annoying, prolonged headache and a trip to the eye doctors for Kat to

give in.

He gets cheap frames he has /very/ little intention of actually wearing, and a pair of contacts he considers his lifeblood, and that’s that… for a while.

The glasses sit in a desk drawer until Katsuki realizes they’re more comfortable for early mornings when he /doesn’t/ want to have to explain why he’s got bruises from bumping into shit, and they’re better for studying late at night, too, when he’s too tired to drag himself to

the bathroom to do the whole contacts routine.

He sure as hell doesn’t tell anybody… until his friends inevitable catch him doing homework in his room, comfy and relaxed and fully glasses-ed out, glaring down his nose at his work.

Reactions vary—Denki and Sero think it’s fucking hilarious, Mina tries to get him to let her try them on. Eijirou… well. Is Eijirou.

He’s as un-weird about it as he is about everything concerning Katsuki, meaning no one ever hears the end of it.

In class it’s “Where are your glasses” and in the dorm it’s “do you need me to go get your glasses” and the second he fucking wakes up Eijirou is snuggling against him, trying to get Katsuki in his glasses.

And he doesn’t say anything about it as long as humanly possible.

Because Katsuki isn’t stupid, but he also left about ninety percent of his fucks to give in his formative years, and his boyfriend’s apparent fixation with him and his sight is one tiny thing at the bottom of a list of shit Katsuki should probably care more about.

It’s not like things really change, even if sometimes Eijirou kisses him, and fits his fingers over the sides of his glasses, nudges them with his nose until Katsuki huffs and sets them aside.

Eijirou gives him a flash of disappointment, or a sigh, or a pout, and Katsuki nearly calls him out on it when Eijirou blushes watching Katsuki wiggle the frame up his nose when they’re studying.

And maybe, /maybe/ Katsuki gets a little tired of beating around the bush.

He likes his issues tackled head on, thank you very much, and if Eijirou is too much of a pussy to admit he likes Katsuki’s new digs, Katsuki will damn well make him.

So, he pulls Eijirou into his dorm room, and shuts the door, and then drops down to his knees in his glasses.

“Oh!” Eijirou says, one massive hand coming to rest on top of Katsuki’s head. “Hi! This is new.”

“Is it?” Katsuki says, and tips his head to the side. He presses his thumbs into Eijirou’s hips, and backs him against the door, shuffling forward to glance at Eijirou above his glasses. “You sayin’ I’ve never sucked you off before?”

Eijirou laughs, and pets Katsuki’s head. “Mm… not quite. Never this eager though.”

Katsuki’s smirk is inevitable, downright indecent pared with the way he presses his cheek into Ei’s crotch, against his intimidatingly thick cock.

“What can I say?” He presses his lips to the front of Ei’s pants and earns himself a quiet moan, Eijirou’s hand slipping down to push through his bangs. “I was excited to see you.”

“Sure,” Eijirou coos, and Katsuki shivers when he gives his hair a gentle tug, not hard enough to hurt.

There’s a little pause as Katsuki reaches up, works his fingers into Eijirou’s pants and gets them over his hips, his cock hanging heavy between his legs.

“Katsuki,” Eijirou says, and Katsuki answers with a purr, leaning forward to bite gently at Eijirou’s hips. “/Katsuki./ Your glasses, babe.”

“Hm? What about them?”

God, Ei smells good. Like soap and heat and sweat, soft on Katsuki’s tongue as he works it over the mark darkening on Eijirou’s thigh.

He has to be careful to avoid pressing his glasses into Eijirou’s skin, but it’s not impossible, and it’s /more/ than worth it based on the way

Eijirou’s cock is filling out against his cheek.

“What /about/ them?” Eijirou laughs. It’s a little nervous, and a little breathless, and it makes Katsuki feel heady and powerful when he dips down and presses his lips to Eijirou’s balls.

“You’ve—/ah/—you’ve g-got to take them off, right?”

Katsuki sucks one of Eijirou’s balls into his mouth with a quiet groan, shifting on his knees to press closer.

“D’you wan’ me to?” he asks, and glances up, takes in Eijirou’s raging flush at the way his cock sits against Katsuki’s cheek, arched up to his hairline and dripping precum onto his skin.

His glasses are skewed, but Eijirou doesn’t seem to mind, swallowing and reaching down to adjust the way they sit on Katsuki’s nose.

His thanks comes in moving up to kitten lick the side of Eijirou’s cock, over a sensitive vein, closing one eye as Eijirou’s erection twitches against his face.

“No,” he breathes eventually, and Katsuki smiles, reaches up and wraps his hand around the base of Eijirou’s cock.

“No?” he repeats, and gives Eijirou’s cock a slow, torturous stroke.

Eijirou whines and fists his hands harder into Katsuki’s hair. “Fuck, you’re doing this on purpose.”

“I’m doing a lot of thing on purpose,” Katsuki says, and mouths sideways over Ei's cock. “But you’re not subtle, babe.”

He rests the head of Eijirou’s cock on his tongue and lets Ei drool precum into his mouth, fighting down a grin when Eijriou tips his head back with a moan.

“I wasn’t trying to be,” he protests, and Katsuki feels the hands in his hair tug again. “You’re so sexy—”

“In my fucking glasses, Ei?”

“In /anything,/” Eijirou breathes, and Katsuki yelps when Eijirou grinds his cock forward a little more, feeding Katsuki enough cock to wrap his lips around.

“The glasses, though…” he breathes, and Katsuki’s eyelashes flutter as his tongue struggles in his mouth. “They make you look so pretty ‘n smart. All intelligent and shit.”

Katsuki is about to pull his mouth off of Ei’s dick to argue that he looks intelligent and shit /all/ the time, but Eijirou forces him deeper with the hand in his hair, and Katsuki grips his thighs with a moan.

“They make you look like a sweet little nerd,” he breathes, and Katsuki glares up long enough for Eijirou to pull his hair hard enough to sting. “Make me wanna ruin you.”

Oh. Oh, that does terrible things to Katsuki’s dick.

His brain is a little fuzzy as he catches his breath around Eijirou’s cock, and then he’s moaning, scrambling at Eijirou’s thighs with his nails and trying to lodge as much as his boyfriend’s cock down his throat.

“Of course you like that,” Eijirou says, and Katsuki mewls when Eijirou’s hips thrust forward, his cock shoving into the tight passage of Katsuki’s throat.

“That’s why I like your glasses, baby—you’re so smart, and pretty, and sexy, and you’re even more eager to be a tight little hole for me to fuck.”

Katsuki fights the tears beading in his eyes long enough to glance up Eijirou’s body, to slide his hands under Eijirou’s shirt and drag his nails down his taught stomach.

“That’s my pretty boy, my good slut.” Eijirou holds him down on his cock as Katsuki tries desperately to

breathe, his head swimming and his thighs rubbing together on the floor. He /wants/ to be Eijirou’s hole, wants whatever he does, including these stupid glasses.

Eijirou pets over his cheek, and Katsuki swallows, delighted at the way it makes Eijirou hiss and shift his weight.

“’m gonna fuck your throat, okay, baby? Keep your glasses on for me, they look so fucking good, Katsuki—”

Katsuki’s moan is outweighed by Eijirou sliding out of his mouth, slipping a thumb into the corner of Katsuki’s lips before he starts to /ruin/ him, shoving that massive

cock in Katsuki’s mouth. And he’s just a hole, just Eijirou’s pretty hole while he sits there and takes it, /loves/ it, his glasses skewed on his face but very much still on his nose, exactly where Ei wants them.

“That’s good, so good,” Eijirou breathes, as Katsuki’s ears redden with the loud squelching of his throat. “You’re so good for me Katsuki, /nnn,/ love you, love your glasses—/fuck—/"

Eijirou pulls Katsuki off of his cock by his hair and Katsuki coughs, sputters as his throat is freed, his mouth wet and messy with fucked out spit.

“Eijirou,” he rasps, and digs his fingers inro Ei’s thighs. “C’mon, fuck me, p-please—”

“Hold on,” Eijirou pants, and Katsuki pushes himself up on his knees, fighting the firm grip in his hair. “I said hold /on,/ Katsuki. Fuck, fuck, I wanna cum on your face, on your glasses—”

“Oh god,” Katsuki moans, and shoves forward enough to lick to head of Eijirou’s cock desperately. “Please, please, on my fucking face, get it in my mouth—”

Eijirou yanks his head back /sharp/ when he cums, the first stripe shooting up Katsuki’s cheek, onto his glasses, across his nose, in his mouth.

Katsuki knows Eijirou cums a lot, but he’s never been as grateful for it as he is now, dripping with spend off of his lenses and into

his mouth, sitting on his tongue as Eijirou catches his breath.

And then he sinks to his knees, holds Katsuki by the face, crashes their mouths together. He’s moaning and whining onto Katsuki’s tongue, twisting his tongue around the cum painted over Katsuki’s lips, and it

presses Katsuki’s glasses into his skin, in a way he can’t even bring himself to mind.

And when Katsuki’s contacts go missing for days at a time, he doesn’t even bother looking for them until Ei comes calling.
