What if, when Bakugou had guarded Izuku at the Hot Springs, he'd been unable to resist a peek? What if he'd got caught?

———

The boys returned to their room damp and completive, and found Izuku reading on his futon, humming to himself.
He turned to smile brightly at them as they filed in, "hey guys! Nice bathe?"
There was a pause, but Sero initiated the 'everything's fine' protocol quickly enough. "Great!" He replied brightly, "Bakubro has the best abs! And Shouji can hold his breath underwater for ages! It was super cool! Denki even managed to keep his quirk under control!"
"That's amazing! Though I'm not surprised about Kaachan! We've been training together since the start of the year and he works really hard!"

Bakugou determinately followed the script, though he was in no mood too. "Of fucking course I have the best abs! I wouldn't have to do anything to be more muscular than you fucks!"
"Kaachan!" Exclaimed Izuku, "they all have great muscles! Have you seen Kiri's biceps!!?!??"
The redhead flushed with pride, and Bakugou scowled - Izuku had deliberately complimented the one guy, he wouldn't insult. He just tched and squatted down on his futon.

"Okay Tokoyami?" Asked the greenette, "you seemed a little nervous to go..."
"Twas devilry." The teen replied from his corner, still shaking slightly from the experience.
"He was so adorable!" Exclaimed Kaminari, "he actually brought little black swimming shorts with pentacles on it to wear! He was so- mmpf!"
He was stopped from teasing the shy emo further by a well aimed pillow from the greenette.
"Hey, what was that for!" Grumbled Kaminari.
Sero chuckled, "you tease the edge lord, mama Zuku'll- mmpf! OOOH OJIRO IT IS ON!"

And thus began the ultimate pillow fight. Izuku used a helpful stealth quirk so he could just sit back and watch. The only way anyone would notice him, was if they'd intended to approach him before he'd activated it. Which was why he jumped when someone gently touched his arm.

He turned to find Bakugou had settled down beside him. "The baths are probably empty now nerd. If you want to go... I'll keep watch for you."
The blond gave Izuku a side long glance and the latter's eyes widened, "won't that be a hassle for you Kaachan?"
"Excuse to avoid these dipshits for half an hour? I've no complaints."
"Oh..." Izuku looked away for a bit, then sent his companion a shy smile. "Then yes please.."
"Follow after me in ten minutes." Grunted the blond, standing up and stomping out the room, with a short, "toilet" in reply to Kirishima's questioning gaze.

Izuku scanned the room, but Shinsou was occupied explaining what was going on to Todoroki, and how freezing pillows then throwing them was unfair play. Iida was animatedly telling the class it was past curfew and they needed to be up early the next day. Tokoyami was listening to heavy metal sharing earphones with Jirou in a corner. And the rest were fully engaged in the intense pillow fight... apart from Aoyama who was... looking right at him.

Before he could do anything, Aoyama carefully lifted his hands and signed in his lap, hidden from those near him.
Go mon ami, I'll make sure none of them come looking.
Izuku swallowed a lump in his throat.
Why Yuga?
Beautiful people should help each other out, no?
He stifled a laugh.
They should, come tell me if I can ever return the favour!
I will. Now go.

He got up, and carefully made his way to the door, slipping out and padding down the stairs.
He exited the main house and over to the hot springs, listening to the sounds of cicadas. He could see Kaachan's silhouette edged in gold from the electric overhead light as he approached.
He looked calm, eyes closed and leant against the wall beside the doors.
Izuku stood watching for a bit before letting his footsteps be heard by the blond.

"It's empty." Bakugou said quietly, opening ruby red eyes to look at him.
Izuku dipped his head, feeling uncharacteristically meek. But then Bakugou was being uncharacteristically gentle and quiet. It was strange, to both.
Not sure what to say, Izuku settled on silence, slipping through the door to the men's baths.

Bakugou closed his eyes again, fighting the urge to take a peek as the soft sound of clothes falling to the floor echoed quietly through the baths, easy for him to hear due to an air vent above his head.

A small gust of wind shifted the string beads of the entry teasingly and the blond groaned internally as his strength of will faltered.
Quietly he peered through the veil into the changing rooms and his heart stuttered at the sight.

Izuku was built beautifully, his slim waist, muscular but slender legs and perfect ass better than Bakugou had ever imagined, not that he had obviously imagined his childhood friend and victim naked. Obviously. That would be very very wrong.

What horrified him were the scars, marring his perfect form with cruel blotches of discolouration and slices of ivory white, made more obvious by the flush of the rest of his perfect freckled skin in the steam from the hot spring.
He'd imagined burns, of his own doing, but saw few if any. They were nothing in comparison to the whip marks, stab wounds and even cigarette burns that marred Izuku's figure. Still made him feel sick though.

Bakugou couldn't draw his eyes away. And as he raised them slowly over pearly collar bones, sharp jaw line, and plush lips, he finally and horrifyingly met frightened emerald eyes.
Izuku had caught him looking, and Bakugou was going to commit seppuku (ritual suicide by stabbing your abdomen).

Before he could furiously apologise and sprint into the forest never to be seen again, Izuku flinched away from his gaze, his arms covered in neat scars attempting to cover the worst of the damage as he shuddered in shame.
"I'm sorry y-you had to s-see..." he whispered, the stammer almost unfamiliar at this point, catching the blond off guard.
Bakugou couldn't help it, "nerd, I'm the pervy shit that looked. I should be apologising."
Izuku flushed a little reaching for a towel and trying to hide as much as he could. "B-but still...it's... it's a horrible sight..."

Well, he was in deep shit anyway. Might as well keep wading.

Bakugou moved into the changing room noting but for the moment ignoring the way Izuku shifted uncomfortably and wouldn't meet his gaze. "Izuku...you're beautiful."
He reached out hesitantly but Izuku flinched away and wouldn't meet his eyes, "don't lie Kaachan...you're the only one I can always trust to be honest with me..."

The blond swallowed, reaching out he gently took one of Izuku's hands in his own and raised it to his lips. Without breaking eye contact with a now blushing Izuku, he kissed it.
"Izuku, you are fuckin' gorgeous."

The greenette opened his mouth but only a fragile whimper escaped him. Taking the strong blush as a good sign, Bakugou continued to push his luck, raising Izuku's hand further to place a kiss on the first collection of cutting scars near his wrist.

The hot springs were silent, save for the breeze running through the forest outside, and Izuku's shallow nervous breaths as Bakugou slowly trailed kisses down his arm, sharp ruby eyes holding him in place with earnest desire and something else Izuku didn't or wouldn't recognise.

At his shoulder, Bakugou hesitated, though whether it was because of the untidy collection on cigarette burns, the deep scar that betrayed the time Inko almost cut his arm off, or because he simply didn't know where he was going, Izuku didn't know. He was mesmerised by ruby eyes and it was getting difficult to think straight. Like how Bakugou Katsuki was kissing him and looking at him like that. How they were alone, and the blond could see all his scars. How there was no one on guard. How...how this was even happening.

Bakugou took a nervous gulp, before calmly kissing each of the cigarette burns, tracing the enormous fucking scar - Inko was going to die - and following Izuku's collar bone on a fast track to that slim pale neck, the only place bare of scars but he doubted unharmed.

Izuku let out a moan as he sucked at the shorter boy's jugular, bringing Katsuki out of his own haze sharply. He was actually doing this. But he was breaking his word, He'd promised. Promised himself, Shinsou and Todoroki he'd never pursue Izuku. Never tell. He didn't deserve this. Izuku was just too kind to push him away. Bakugou was taking advantage of him. Again.

Just as he realised, he came face to face with Izuku's perfect lips, parted uncertainly, his eyes dazed and skin flushed deeply making his freckles pop. Bakugou swallowed, his throat suddenly dry, and he pulled away.

"I'm sorry...sorry Izuku..." he mumbled, backing away from those all seeing green eyes, "please...please forget this...that this ever happened...I won't...I'll never take advantage of you again..."

His back collided with the wall and he turned to stumble out the room when a whisper caught his attention.
"Kaachan...please..."
He froze up, just as he parted the beaded strings of the entry way.
"Don't leave...need you..." whispered Izuku weakly.

Bakugou growled as all his resolution evapourated. If Izuku needed him it was different though. Or at least, he hoped that would be enough for his guilty conscience later.

His lips were on Izuku's the next moment, the force of his return knocking them both back so Izuku was leant against the wall. He stripped off most of his clothes as he did his best, first kiss as it was, to send the motherfucking angel back to heaven,
"You're the most intelligent damn person in this shitty place Izuku." He growled against the other's jaw, his hand curving around Izuku's waist to bring their hips flush. "The way you can analyse a person or situation in seconds is really fuckin' sexy."

Bakugou gathered praise was a winner by the pornographic moan that elicited, and he leapt at the opportunity. He had a hell of a lot to say.
Lifting Izuku into his arms, grimacing at how light the teen was, he strode toward the hot springs, mouth barely leaving Izuku's.
"Your hair...fuck I love your long hair. I said it was silly but damn when you have it up in a bun I can't keep my eyes off you."

"Kaachan-"
"Shut it nerd, I've a lot I haven't bin sayin'."
The greenette flushed deeper, and Bakugou strode down the steps into the hot water, settling on a bench with Izuku still on his lap, beet red and mumbling nervously.
"Your muttering should be annoying, but it's the fuckin' cutest thing." He growled, unable to resist the pull of the other, nibbling at his neck and loving how Izuku arched into his touch.
"And your body....fuck Deku, you've been my wet dream for years."

"Kaachan...you don't have to say things like that..." mumbled Izuku, looking away from him nervously. Bakugou rolled his eyes and took Izuku's hand, "I know you feel guilty and all but you don't-"
Bakugou grabbed Izuku's right hand and pulled it underwater pressing it against his erection. "M'not fuckin lyin' Izuku. Everywhere your body touches mine, my skin burns. I want you so badly, it's taking all my self restraint to even stay still right now. When you moan, kami I nearly came just hearing you. Mouths can lie, but dicks fuckin' can't."

Izuku had frozen up, and he hesitated just enough to have Bakugou panicking that he'd pushed too far when the greenette giggled.
"What!" Growled Bakugou, flushing to his ears and staring at the shorter teen straddling his lap, he was trying to sound outraged but he was just too relieved Izuku wasn't running away looking disgusted... to be honest with himself, he just sounded fuckin' whipped. "You laughing at me?!?! Hah?"

Izuku's eyes raised to his, filled with mirth and warmth and Bakugou froze up, the flush spreading to his neck and shoulders.
"You really can't do romantic can you Kaachan?" He snickered and the blond pouted. "Just like, kiss me breathless, carry me into the hot spring and shove my hand on your hard dick as reassurance that I'm not ugly..."

When you put it that way. Bakugou opened his mouth to apologise but Izuku continued.
"So unromantic...and yet so you, I couldn't have really imagined this going any other way, not that I ever imagined..." Izuku used the hand Bakugou wasn't holding to his cock to guide Bakugou's free left hand to press against his chest, his voice turning shy again. "Anyway, for some dumb reason, you and you're crass flirting have my heart trying to escape my rib cage."

Bakugou mustered a smirk, "''course they do, I'm Bakugou fuckin' Katsu-gah!"
Interrupting his mostly joking proclamation was a firm tug on his cock that had him almost swallowing his own tongue. "D- Izuku! Ngh..."
"What were you intending when you shoved my hand down here?" Teased Izuku, eyeing him under his lashes with a playful grin.
"Uh...well...ah...hadn't thought that fuckin' far. You were meant to slap my face into the wall about ten minutes ago....mnn!"
Izuku flushed, "I'd never!"
Kaachan managed to pull of a full sentence without groaning. "You should have, I don't deserve you even lookin' at me Izuku. Let a-alone...mn."
A particularly furious tug forced his next sentence from his mind and before he could reach for it, Izuku's lips were on his again and he no longer remembered what he was worried about.

Then Izuku's hand was cupping their dicks together, and Bakugou was not having him getting them both off alone. Reawakened a little, he lowered his own hands under the water, one joining Izuku's the other unable to resist squeezing one of those perfect ass cheeks.
He swallowed the other's gasp and closed his eyes, trying to remember every aspect of this before his alarm clock went off or he finds out what the mushrooms Kaminari put in the curry actually were.

The light slaps of skin on skin and the rippling of water. The cool breeze rustling the trees outside. Izuku's erratic soft breaths and his own substantially less attractive pants and groans. How his hand felt against Izuku's smaller one. The firm muscle of the other's ass against his palm. The energy sparking between them. The feeling of trust and forgiveness, both of which he didn't deserve... that almost made him cry.

His orgasm took him by surprise. He'd been so lost in the moment he hadn't registered the strength of the building pleasure until it overflowed.
He gasped out Izuku's name, his toes curling against the tiles.

When he came back to the present he noted with relief he wasn't the only one who came. He leant forward at the same time as Izuku, and they rested their foreheads against each other as they both caught their breaths, the drip of water the only other sound.
It was disorientating how quiet it was, compared to the magnitude of what had just happened. Bakugou's mind was reeling, well trying to in the groggy post orgasm haze.

Izuku pulled away first, Bakugou was certain if it wasn't for his hands resting on the other's waist, the greenette would have got off him too, his eyes suddenly nervous and scared.
"Um, Kaachan," he began quietly, "I'm-"
"Nope."

Izuku blinked at him, opening his mouth again but Katsuki raised his hand to cover those kiss swollen lips. "Nopety nope. If you're apologising I don't want to hear it. Thanking me either. Or anything else stupid your self conscious brain supplied, while I was trying to remember my name after the best fucking orgasm of my damn life."
The greenette released a little pout but was still looking scared.

"Listen. This can be whatever you need it to." Said Bakugou calmly. "Yes I think you're stunning and wonderful, but you can tell me to forget this and I'll at least act like it never happened. If you're interested but not ready that's absolutely fine. If this only happened because I made you feel insecure and needed reassurance or just felt horny, that's fine. If you want to date that's great, but I will only be happy with whatever you say next if it's honest and will make you feel the least stress, so look me in the eyes and tell me what you need this to be. And not what you think I want this to be. Got it Izuku?"

The greenette swallowed nervously, but his shoulders relaxed a lot. He nodded hesitantly and Bakugou removed his hand.
The blond wasn't sure what he expected, but Izuku leaning in, to cry into his neck wasn't it.

He raised his hands, one to rub in circles on Izuku's back and the other to his hair like he'd read in psychology books. He'd been reading a lot about abuse victims, panic attacks, PTSD and trauma, hoping to learn the best ways to take care of Izuku, he prayed the time hadn't been wasted.

They must have stayed like that for five minutes, it was definitely dark outside, and Bakugou prayed no one would come looking for them.
Eventually Izuku spoke quietly. "I...I feel a lot. So much, but...I don't know what it is."
The greenette moved to pull away but Bakugou gently pulled him back into the hug. Izuku sniffled then kept going. "It's...it's hard to know what love is like if you weren't shown it before...but I feel warm," he raised his hand to his chest, "here. I almost can't breathe but in a good way...when you talk like that- considering my feelings so carefully, it makes me happy...but different happy...but I'm so confused..."

His words deteriorated into mumbles and Bakugou cupped the back of his head, pulling him down to gently kiss the greenette's forehead. "You're okay. Breathe."
Izuku did as he was told.
"Now, I think what I'm gonna take from that is you need a lot more time and fucking friendship before you'll be ready to deal with more than that. So, I'm going to pretend this didn't happen, swear to you I don't have any expectations of more, and continue trying to be a decent friend to you. If you ever need or want me as more than that, you tell me, and if you never do, know I'll be okay, yeah?"

Izuku sniffed, nuzzling into his neck a little and making Katsuki's heart jump. "When did you get so kind?"
Bakugou hummed, "when I took my head out my arse and saw what was right in front of me."
He squeezed Izuku tentatively, determined not to pull away until Izuku initiated. Which he did a few minutes later.

"We should head back Kaachan...Shoto and Kiri are on the stairs heading down to come look for us."
Bakugou sighed, not questioning Izuku sensing quirk which suddenly rendered him coming down here to 'keep guard' completely pointless. "You never got to wash properly."
Izuku smiled softly, "I got to be closer to you."

He got off Bakugou's lap and left the blushing teen to climb out the hot springs.
After remembering where he was, the blond followed and they changed in companionable silence before returning together, and if they held hands all the way to the main building, that was their business.
