Chapter Text
The Bakugous and Midoriyas hadn’t gone on a joint family vacation in a long, long time. When the two kids were little, they would do everything together, from camping to going to the ocean. In middle school, when Katsuki began to ignore Deku in favour of hanging out with boys, the family vacations slowly decreased until they completely stopped altogether.
Now, only a week before they would graduate high school, they were here. Okinawa was supposed to be a relaxing vacation spot, but Katsuki could say with confidence that he did not feel relaxed.
“You want us ,” he said, gesturing between him and the green-eyed girl beside him, “to share a room ? And you don’t see anything wrong with that?”
“Why would we?” Midoriya Inko asked, sounding genuinely confused. “You’re both friends again, and you used to share rooms all the time when you were little!”
“Hag, you don’t have anything to say about this?” Katsuki barked, turning to his mother. The evil bitch was smirking at him, her arms crossed over her chest.
“Why would I?” She echoed her best friend. “Like Inko said, you used to do it all the time!”
‘ Oh, I’m going to murder her the first chance I get,’ Katsuki thought evilly, already imagining all the ways he could do it. ‘ She knows how I feel about Deku. She’s torturing me on purpose.’
“Now, now,” Masaru soothed, patting his wife on the shoulder. “You can handle it, can’t you?” He looked at Izuku with wide eyes. Deku grinned, although Katsuki could tell her smile was a bit wobbly.
“I- I don’t mind,” she said. She turned those big eyes to Katsuki nervously. “As long as Kacchan is okay with it…?”
Well, fuck . How the fuck was he supposed to say no to that? Sometimes, Katsuki could swear that Deku knew she could get him to do anything just by flashing those emerald greens at him, but she was so oblivious that he knew it couldn’t be true. If she had any idea about the kind of thoughts Katsuki had about her, she would run for the hills screaming. The thing was, Katsuki knew that he didn’t deserve her. After the way he had teased and belittled her in middle school to try and escape his own fucked-up feelings, he hardly deserved to breathe the same air as her. Sometimes, he was amazed that she was ever able to forgive him.
“Fine,” he snapped, snatching the room key out of Auntie Inko’s hand. “Come on Deku, let’s go.”
“Meet us in the lobby for dinner at seven!” Inko chirped after them. Katsuki shrugged and grabbed his bag, slinging it over his shoulder. Deku pulled her suitcase behind him as the two headed for the elevator, taking it up to the fourth floor where their room was. Bakugou was stewing the entire trip there, his mind a jumble of different feelings and thoughts about the situation. When they finally reached the room, he had calmed down enough to realize that this wouldn’t be so bad. Sure, he was hopelessly in love with Deku, and sure, he would probably wake up with a boner every single day of this trip, but he could hide it. Lord knew he’d hidden it from her plenty of times in the past.
Deku opened the door and stepped inside. Katsuki made to go after her, only to slam into her back. She stumbled forward into the room, nearly tripping all over herself. Katsuki scowled at her and entered the room. “Why the fuck did you stop like that, nerd?”
Then, he looked up, and he realized. There, in the middle of the room, was a perfectly made queen sized bed. And nothing else .
“Um,” Deku said, glancing at him with red cheeks. “Do you think it was a mix up?”
“No,” Katsuki ground out through clenched teeth. His mother had been the one to book the rooms, and he had no doubt that she had done this on purpose. What kind of mother encouraged their son to stay alone in a room with a girl they had feelings for? He was seriously going to kick her ass! “Just… don’t fucking worry about it, alright? I’ll sleep on the floor or some shit.”
“For four days?” Deku squawked indignantly. “No way! We can share the bed, Kacchan, it’s fine!”
“Deku,” Katsuki said, warning in his voice. The green-haired girl was having none of it, though.
“If you’re really that uncomfortable, we can make a pillow wall,” she said, dragging her suitcase to the edge of the bed. “But you’re not sleeping on the floor.”
Katsuki could already tell that there was no way he was going to win this argument. “Fine,” he sighed. “Whatever. Just get changed so we can go get dinner, okay? We’ll worry about this fucking mess later.”
“Deal,” Deku smiled. “I’m going to go change in the bathroom, be right back!”
As soon as the door closed behind her, Katsuki practically collapsed onto the mattress. This was going to be a long vacation.

“What kind of a mother are you?” Katsuki hissed to his old hag. Deku, his father and Deku’s mom were all chatting about something-or-other across the table, leaving them distracted enough for Bakugou to confront Mitsuki. The bitch sipped at her miso smirk, although it didn’t hide the smirk on her lips.
“Whatever do you mean?” She asked innocently. “I’m only trying to help my son deepen his friendship with his childhood friend, that’s all.”
“Bullshit,” he snapped, although he kept his voice low. “Why the fuck are you doing this to me? One bed ? Really?”
“It was all they had open,” Mitsuki shrugged. Katsuki glanced around the restaurant they sat in. It was the hotel restaurant, and there were hardly any people in it. He looked back at his mother in a deadpan expression.
“Bull. Shit,” he said again, enunciating the two words. Mitsuki barked out a laugh.
“Deal with it, Katsuki,” she said. “Maybe you’ll even grow some balls and confess before I’m too old to even be a grandmother!”
“You- you-!”
“Katsuki-kun?” Inko asked, frowning a bit at him. “Do you not like your soup?”
All eyes were on him now. He shook his head and begrudgingly sipped at the soup. “S’ fine,” he grumbled. He side-eyed his mother with a harsh glare. “Although the air in here kind of smells like bullshit .”
Mitsuki smiled into her rice bowl. “How odd.”

Deku climbed into bed, settling down into the covers. She was wearing nothing but an oversized shirt that Katsuki was ninety-nine percent sure she’d stolen from him, and the tiniest pair of tight athletic shorts. When she’d come out of the bathroom, he’d nearly had a fucking stroke.
He was sitting stiffly on his side of the bed, a carefully constructed pillow wall separating them. There was some b-list horror movie playing on the television in front of them, although he wasn’t paying the slightest bit of attention to it. Once Deku was comfortable, she stopped wiggling around and smiled at Katsuki. “Are you excited for the beach tomorrow, Kacchan?”
“Sure,” he said dryly, not taking his eyes from the screen. He was afraid of what he might do if he did. “It’ll be soooo fun.”
“I think so too!” Deku said, missing his sarcasm entirely. “We should probably go to sleep soon so we’re not tired tomorrow.”
Katsuki inhaled slowly, reaching down to grab the remote to turn the t.v. off. Deku turned off the lamp on her side of the bed, encasing the two of them in darkness. After a moment of silence, her soft voice echoed in his ears. “Goodnight, Kacchan.”
“Night, Deku.”
Katsuki awoke long before the sun rose, blinking the exhaustion out of his eyes. The first thing he noticed was how warm he was, despite the cold chill in the room. The next thing he noticed was that his nose was buried in a mop of green curls, the long strands tangled around him and across the pillows they were sleeping on. The next was that the pillow wall that he had carefully made hours before was nowhere to be found.
Every trace of sleep fled from his body when he realized exactly what he was doing. At some point in the night, either him or Deku had wriggled past the wall, and now Katsuki was spooning the smaller girl as tightly as he could. Her ass was snug against the crotch of his pants, and his cock was harder than it had ever been before. One of his arms was underneath her torso, curled up to rest on the curve of her waist that faced the ceiling. His other arm was curled down over it, resting… resting… He flexed his palm, his mind completely blank for the first time the whole trip. Flesh squeezed in his palm with the movement, soft and supple.
He was cupping Deku’s breast .
He ripped himself away so quickly that he nearly fell off the bed. He only barely managed not to let out a noise of shock, and luckily, Deku had always been a heavy sleeper. The sudden movement away from her didn’t wake her, but rather she turned on her side to face him again, her unconscious body seeking the warmth that had left her. Katsuki stared down at her, his face redder than Kirishima’s shitty hair. Her sleep shirt was rucked up on her toned abdomen, resting just beneath the bottom curve of her breasts. His hand had been under there, pressed against her bare, freckled skin.
He stared down at the offending appendage, blinking a few times in disbelief. He had… he had groped Deku in her sleep without even realizing it. The very thought had his dick pulsing in his pants once again, reminding him of the little issue he had to deal with. He quietly got out of bed and made his way to the attached bathroom, closing and locking the door behind him. He didn’t turn on the light, to afraid of somehow waking the sleeping girl up. He braced himself against the bathroom counter, squinting at himself in the mirror.
“Okay Katsuki,” he whispered, studying his dark reflection. “You didn’t mean to do it. You were asleep. What she doesn’t know won’t hurt her, right?”
‘ But you liked it,’ his inner lizard brain whispered. ‘ You want to do it again.’
“Yeah, well, I’ve wanted to do that since I was fucking twelve!” He hissed at his reflection. He could swear that it was mocking him. “That doesn’t mean I’m going to do it!”
‘ Whatever you say,’ the lizard brain thought. He groaned, crouching down on the floor with his hands still gripping the edge of the counter above him. He took a few deep breaths, trying to erase the feeling of her soft skin from his mind. It was basically impossible. He allowed himself to fall on his ass, scooting back until his back was pressed against the wall. He reached down and palmed the bulge in his sweatpants, groaning from the pleasurable friction. Was he really about to rub one out with Deku asleep in the next room?
‘ Yes, you are,’ he thought to himself. Yeah, he was. He took his cock out of his pants, tucking the waistband underneath his balls. From the first long, rough stroke, he already felt like cumming. He let his head thunk against the wall and he closed his eyes, picturing Deku’s sweet face in his mind. Those apple cheeks, plush pink lips, fucking phenomenal ass… he stroked himself a little faster now, a bit of moisture at the tip of his dick slickening the process. The feeling of her tits in his palm appeared at the forefront of his mind once more, and he couldn’t help the soft growl that left his lips. Fuck, fuck . Her nipple had been hard, he realized. Her unconscious body had liked it, too.
It didn’t take long before he was shooting all over his hand, his free hand clasped over his mouth to muffle any noises he might make. Once he came down from his high, he let go of his mouth, panting and trying to catch his breath. He had never felt more pathetic in his life.

Izuku watched Katsuki strip his shirt off, a light blush rising to her cheeks. She’d had a bit of a dirty dream about him the night before, and it was not helping her staring problem. Kacchan had always been unfairly attractive, but he seemed to only get even more so with age. The night before, she’d had a dream that he was cuddling with her, rocking his hard dick against her ass slowly. The friction of it had been nearly enough to make her cum, and one of his hands had been palming roughly at her breast, only adding to the pleasure.
When she woke up the next morning, Kacchan was already in the shower. She was ashamed to admit that she got herself off quickly before he came out of the bathroom. She hurried her way in with nothing more than a shy greeting, using the hot water of the shower to wash away her sins. Now, Kacchan was dressed in nothing but his swim trunks, every muscle in his torso on full display. She bit her lower lip and looked away from him, down at herself. She was wearing her new swimsuit underneath the t-shirt she was wearing, but she was a bit embarrassed to take the shirt off. She’d never worn a bikini in front of Kacchan before… what if he thought she looked bad, or gross? The two of them had started working out together in their first year of high school, after they became friends again, so she at least knew that she wasn’t overweight or anything. But what if Kacchan liked girls with a little more pudge, like Ochako or Yaomomo?
“Aren’t you going to swim with Katsuki, honey?” Auntie Mitsuki asked her, nudging her with an elbow. Izuku looked at her, then back at Kacchan, who was watching her expectantly. She sighed and stood up, grabbing the hem of her shirt to pull over her head. Her bikini was black with dark green trim to compliment her hair. She could admit that it was a nice suit, but did it look bad on her? She tossed her shirt down onto her towel without looking at Kacchan. She smiled at their parents and flipped her head upside-down, gathering her long curls into a high ponytail to keep them at least somewhat tame when they got wet. When she looked back up to take a peek at Kacchan, he was looking at the ocean horizon with his arms crossed. She let out a little breath of relief that he wasn’t staring at her.
“We’re going now!” She told the adults, sidling up to Kacchan’s side. “Come on Kacchan! Whoever finds a sand dollar first is the winner!”
He looked at her and smirked. “You’re so fucking on.”
(x)
Katsuki was in hell. Deku’s bikini hugged her curves and left nothing to the imagination, showcasing her ample cleavage and her muscled thighs. Her waist was trim and toned from all the working out they did together, and god did he want to lick her all over. It was one-thousand times worse when they went into the ocean and she came out soaking wet, tantalizing water droplets rolling over her tan freckles. What he wouldn’t give to lick them off one by one.
He ended up finding the first sand dollar of the day, but when Deku pouted at him, he gave it to her. It was a tradition they’d had from every beach trip their family took together; whoever found the first sand dollar of the trip had bragging rights until the next trip. Every time without fail, no matter who had found the first shell, Deku ended up taking them all home with her. What? She liked them, and Katsuki had no use for them. Leave him the fuck alone.
Hours later, Deku’s cheeks and shoulders were beginning to look a bit red, so he led the two of them back to the little camp their parents had made. Their mothers were gone, and when Masaru woke up from the nap he was taking, he explained that they’d gone to walk around the shops on the edge of the beach for a while. Katsuki collapsed onto his towel underneath the umbrella, closing his eyes. He was aware of Deku laying down beside him, her soaked skin just barely brushing against his.
“Thanks for the shell, Kacchan,” she said quietly. Katsuki grunted but didn’t open his eyes. He needed a break from staring at Deku like some sort of stalker. If he had only opened his eyes, he would have seen Deku studying him right back.
That night, Katsuki constructed the pillow fort for the second time, but this time, he was practically hanging off the edge of the bed in an effort to keep far away from Deku. The green-haired girl shot him a strange, slightly hurt look, but didn’t argue as she turned off the lamp lights.
The two sat in silence and darkness for a long while before Katsuki sighed heavily. Although he couldn’t see her, he could somehow tell that Deku was still awake. “What, Deku? I can hear you thinking from all the way over here.”
“Oh, really?” she sniped. “From all the way over there?”
He sat up, reaching to his own bedside table to flick on his lamp. The brightness made him blink a few times, but he focused back in on Deku quickly. She was sitting up, glaring at him with her sleep-mussed curls and tired eyes. She looked so fucking cute that it physically hurt his chest. He took a deep breath and exhaled slowly. “Why are you being so pissy?”
She swallowed hard before she stared down at her hands in her lap. When they were seven, Deku had been in a really bad car accident that ended up killing her father. He right arm and hand were somewhat crooked, because her arm had ended up tangled in the metal of the passenger side door. It was a miracle she was alive. Katsuki had never minded the scarring- in fact, he found her crooked fingers kind of endearing- but the way she was staring at them now made him wish they weren’t there. He wanted her to look at him .
“You know, don’t you?” She asked quietly. She still refused to raise her eyes. “You probably heard me last night or something, right?”
“What?” Katsuki asked, confused. She scoffed and finally looked at him, her cheeks flushed with embarrassment.
“You know I had a wet dream about you last night, don’t you? That’s why you’re acting like this!” She gestured to his entire body angrily. He could swear in that moment that his heart completely stopped in his chest. She didn’t seem to notice, because she kept talking. “You’ve barely looked at me all day, and you- you’re acting standoff-ish! Look, I’m sorry that I have feelings for you, but I can’t control them, and I don’t want to lose you as a friend-!”
Katsuki reached out and pressed his palm against her mouth, silencing her. Her eyes, the only part of her face left visible, were wide as she waited for him to speak. He tried to gather his words for a moment before he spoke. “You… have feelings for me?”
Deku’s eyes turned from curious to horrified, and she shoved his hand off of her mouth. “Oh my god,” she whimpered. “You didn’t know, did you?” She scrambled back until she was the one on the edge of the bed, and she curled her knees up to her chest in the fetal position. “Oh my god, oh my god , I’m so stupid!”
“Hey,” he said, trying to catch her attention. Her furious muttering didn’t cease in the slightest, irritating him. “ Hey !” He said, louder this time. She finally shut up and met his eyes. “Answer my fucking question, Deku, and we’ll go from there.”
Deku swallowed hard, but still spoke. “Of course I have feelings for you,” she whispered. “Kacchan is amazing, after all.”
Katsuki’s mouth went dry, and instead of his heart stopping, it was beating out of his chest like a drum. Deku’s hands were trembling when she hooked them around her knees, hugging herself tighter. The position exposed every inch of her muscular legs, all of the tan skin and freckles. Her father had been mixed race, Japanese along with Hawaiian, which was what gave Deku her curly hair and darker complexion. She was so beautiful.
“Deku,” he said, keeping his tone calm and quiet. “If you’re fucking with me-”
“I would never!” She said, snapping her head up. “How could you even think that?”
“Because you’re- you’re you!” He growled. “I figured you found out about my feelings for you and are doing this to not hurt my fucking ego, or whatever.”
“You… have feelings for me, too?” Deku asked. Katsuki clenched his jaw, jerking his head in a single nod. In the next instant, Deku had flung herself into his arms, burying her head into the crook of his neck. Katsuki nearly fell over, but held onto her tight, pressing his nose into the top of her sweet-smelling curls. He took a moment to just bask in this- in the feeling of having her in his arms because she wanted to be there, because she liked him- before he gently pulled away to look into her eyes.
“Are you sure about this?” he asked, although he really didn’t want to. “I… I was a dick to you in middle school.”
“I already told you that I forgave you for that.” She reached up to caress his cheek with her hand, and he couldn’t help but lean into it. She smiled at the surprisingly soft action. “The only question here is if you can forgive yourself.”
He pressed his lips together in a thin line. “Probably not,” he finally said. “But I’ll spend the rest of my life making it up to you, if you’ll let me.”
Her eyes filled with tears and she nodded frantically, leaning forward to smash her lips against his. It wasn’t some sort of explosion, or fireworks like the romance manga tried to claim, but rather something that just felt… right . His skin was tingling all over from the sensation, and he closed his eyes, burying his hand into the hair at the nape of her neck, caressing her jaw with his thumb. She opened her mouth to sigh, and he took the opportunity to lick into her mouth dirtily. The noise she made was borderline pornographic, causing his dick to immediately wake up in his sweatpants. She bit down onto his bottom lip, tugging it between her teeth for a moment before she released it once more. He groaned, tightening his fist in her curls.
He broke away from the kiss, leaning his forehead against hers. They both caught their breath, staring into each other’s eyes intimately.
“Kacchan?” Deku asked, barely a breath against his lips.
“Hmm?” He hummed, entranced by the golden specks in her green gaze.
“Will you have sex with me?”
Record scratch.
