Katsuki looked over at Izuku as the two strode through the plaza, the sun beaming down bringing out those pretty freckles in all their glory.

Hnnnn he’s so soft for the nerd. Secretly of course. He also wants to tear his clothes off and ravage his soft skin, again that’s a secret.

A secret he’ll take to his damn grave because they’re pro heroes now, romance can wait for… whatever, he’s not a coward, it’s just not the right time.

“-but I don’t know why they didn’t check the chest! It was obvious!!”

Oh shit, the nerd was talking. Default to rage.

“HAH!? What the hell you talkin ‘bout loser?”

Izuku blinked then let out a giggle “oh sorry Kacchan, I was just babbling about last night’s episode of Heroic Escapes!”

Ah of course, the new reality tv show where they put a bunch of current and former heroes in escape rooms. It was fun.

“I don’t watch that bullshit” he lied so easily it should honestly be a crime.

“Oh I thought-“

Izuku was cut off by distant screams and so with a look of determination (that he fucking loved) and a quick nod, they were both off.

But as they rounded the corner and saw the building where the commotion was coming from, the sight was unexpected

Fleeing like rats from a sinking ship were men and women, only in underwear. But the odd thing was that they seemed to be trying to cover up by pulling on…? Invisible clothing??

“Did the villain turn their outer clothing layers invisible?” Katsuki hissed as he took a defensive position by the door. Peeking his head around he saw the quirk in action as the crook grabbed a man by the suit jacket and all colour faded to nothing…

… then the shirt he tapped, then the pants as the civilian struggled and wailed. It was a simple car insurance company so there were no security guards. Honestly… what was this assholes problem!?

“Deku, we go in, you take left, I go right- Deku are you fucking listening to me!” He shook Izuku by the shoulder as the freckled hero watched in horror as the latest victim fled the scene.

“Why today!?” Izuku gasped

Huh?!

“Oi! Nerd, what the fuck? I’ve seen your All Might boxers before, it’s not the end of the fucking world idiot!”

But Izuku squeaked and buried his face in his hands. Before he could question this seemingly random reaction a woman screamed inside.

Izuku snapped his head up “let’s go, I’m left.”

He blinked and dismissed the nerd’s earlier response to the situation, fancy being shy about being in your undies, he knew the nerd had a great body, he’d thought about it a lot… ok not now

“I’ll fling in a flash grenade”

“Ok Kacchan, on three”

Everything went perfect at first, until the asshole threw an invisible jacket into Izuku’s face, confusing the shit out of him, then threw a literal woman at Katsuki.

When Izuku dived forward, the villain it seemed, was a fan, distracting Deku by turning his jumper invisible revealing a Deku themed shirt and screaming “I’m so happy it’s you!!! I just wanted revenge for being fired, but to meet my idol!!”

But in that moment, he grazed the tip of his finger against Deku’s hero costume despite his recoil to avoid it.

And now he knew why Izuku seemed to mortified about this villain’s quirk.

Katsuki isn’t one to get distracted in a villain fight. Ever. It’s literally never happened. He was always in the zone, 100% focused and that’s why he was the best. But right now he was absolutely stunned into staring, mouth agape as Izuku’s costume faded into translucency…

Revealing a stunning, ripped muscled, scarred body, naked except for lace boxers.

Wow.

(Three months ago)

When the lingerie company first approached Katsuki with a promise of creating “beautiful and delicate but strong and supportive underwear” with accents of his hero costume, he kinda shrugged and agreed to see what they had in mind.

Of course all the designs were subtle but fashionable and he liked that but as he scanned the pics “two bras, a bralet, a thong… hardly supportive but ok, a knicker… where’s the men’s selection?”

The sales rep’s brows shot to her hairline “o-oh I uhh we, I mea-“

“Make a couple of styles in men’s boxers, I’m gay for fucks sake”

She beamed brightly “of course Mr Dynamight sir!”

(End of flashback)

He watched, stupidly frozen in place as Izuku, no, Adonis dived up and hooked his leg back, bursting forth with a small percent of one for all - Shoot style.

Time slowed down he was sure of it, Deku - naked except for tight dark olive lace boxers with an orange silk “X” ribbon above the little circle cut out that sat teasingly at the top of his round luscious butt cheeks - swung that ‘carved by god himself’ leg around…

And smashed the villain in the face knocking him out.

Immediately, that glorious vision, the most perfect thing he’d ever seen, was gone. Deku’s hero costume colouring back in, ripping the glorious sight away from him.

And of course this made him scowl, absolutely furious at this crime.

Izuku turned sheepishly and whimpered when he saw Katsuki’s anger, holding his hands up In surrender “K-kacchan I- I’m sorry, I-“

Oh…

Katsuki smirked, pouring all of his lust into that devilish grin

“I’m very disappointed in you Deku…” he rasped as he slunk closer, almost predatorily “why’d you have to knock him out! I was enjoying the view!”

Twt limit brb

Izuku stopped his nervous jittering and tilted his head to the side, adorable confusion gracing his face “wh…what!?”

Katsuki took the last step, quickly peeking around to make sure they were alone (except for the unconscious perp). Now that they were barely a few inches apart-

He leant forward, tilting down because he was still a few inches taller “I said, I was enjoying the view… I like seeing you in my colours nerd” he slowly lifted his hand, spreading his fingers across Izuku’s chest on a path upwards.

“Seeing lace stretched across your fine ass is a sight but in my colours… you look like your mine…”

Izuku was by this point so red he looked like he might faint, the firmer he pushed his fingertips into the strong pectoral muscles the more the nerd began to pant

“Do you think you’d like that I-Zu-Ku?” He pushed his fingers up more, curving them around the side of Izuku’s neck with a softer touch and threading them into soft green curls “being MINE” as he said the last word he grabbed those lush locks.

A tiny part of him wondered if coming on this strong was a recipe for disaster but the second he said ‘mine’ and grabbed that fistful of hair, Izuku moaned.

A perfect, soft and drawn out moan, quiet enough for the public setting but loud enough to set a blaze in his gut.

“Answer me Deku”

Izuku’s eyes were sparkling as he breathily replied “yes… I’ve always been yours”

Thank god baggy pants could hide his hard on.

Pressing in closer to share that fact, he whispered into Izuku’s ear “Let me take what’s mine out for dinner tonight then…”

He nipped that soft ear lobe, enjoying the full shudder and sharp gasp “let me treat you good and then take you home so you can show me my gorgeous Deku in my lace”

Pulling back with the intention of teasing the nerd more, he was met with a heavy lidded gaze.

And before he could do anything, Izuku grabbed his hero costume and pulled him in for a strong passionate kiss. It was perfect. Only ending a little too soon for his liking.

“Yes please Kacchan”

The two finally pulled back, slapping cuffs on the villain when they heard sirens

Pretty much the whole time they were filling in the police about the incident, the two kept sending each other long glances. Both obviously anticipating what was to come.

When they got back to the agency, Izuku reached up to give him a kiss on the cheek, giggling as he quickly slipped into the change rooms “I’ll be there in a second Deku… don’t you dare change too quick!!”

As soon as the door closed he grabbed his phone.

Opening his emails he hammered out a message to the lingerie company, vaguely commending them on their stellar job before requesting to expand the line.

This time asking for samples instead of pictures.

Hastily pocketing his phone he pushed open the locker room door “you alone in there Deku?”

“Yep” the cheery reply came instantly so he turned and quickly locked the door behind him.

Because he knew Deku would have bought both of the lace boxers… So why not enjoy this set now and the other one after dinner tonight.

✨The end ✨
