Was this just a rebound?

Summary:

Kirishima is elated to go to the school dance with his most recent girlfriend with big romantic plans. Bakugou comes to see how it will play out.

Notes:

This previously was left as a cliffhanger, but I went in and added a more rounded-out ending as of 2/5/25. :)

Work Text:

Is shitty hair really still talking about this stupid dance? God, it seems like it’s been hours.

“And then, the big crescendo is going to be when they play our song—well it’s not our song yet, but I hope after this it might be, and then we’re going to slow dance in the spotlight and fake snow is going to fall and it’s going to be perfect!!” Kirishima continues to chatter.

“Uh huh.” Bakugou wondered how many times he had told him the new plan or new detail he was adding to woo his latest girlfriend. He couldn’t imagine what shitty song he was imagining he probably was paying the DJ to play. Something cheesy and sappy for sure. And how many times was he going to redo his hair?! It looks the exact same as it does every day. If he wanted it to be special he should just wear it down.

“Dude, when are you going to get ready?” Kirishima finally asked. Ugh, he finally noticed.

“I guess I’ll fuckin do it now. Can’t believe you’re making me go to this damn stupid event. I swear I’m leaving after ten minutes!” Bakugou pushed Kirishima out of his room so he could change.

“Aw, you gotta stay longer than that!! I guess—I guess I’ll meet you there then!!” Kirishima let himself be pushed through the doorway completely, saying his goodbyes before the door was completely shut. Bakugou had to admit that he did like seeing Kirishima so happy and fired up. He had managed to keep this girl interested for a few months and it was usually around this time that the girl would decide to move on and Kirishima would be heartbroken.

He would say he knew it wasn’t love or anything, but he always put 100% into the relationship and tried to make it love. Bakugou wasn’t sure how many times he would have to endure the defeated heartbroken Kirishima, even if it only lasted a few days. It seemed like each time was hurting worse and worse. Guess repeated rejection will do that to a person. But tonight would be different, as Kirishima had said. He worked so hard on the planning, timing, and coordination. There was no way she wouldn’t love it. As much as Bakugou hated seeing Kirishima work so hard for anyone that wasn’t him, he was also rooting for him, to reach that happiness and love and contentedness he’d been seeking the last three years. Although, at least it’ll be public and it’s not like he’s proposing or anything, so how bad could it really go?

Bakugou looked at his hair in the mirror. Should he even attempt to tame it? Maybe try some of the tricks he learned from Best Jeanist? Nah that looked so stupid. Maybe a headband? He tried it but gave up on that too. He looked through his closet, though he knew what he was probably going to end up wearing. Most of his clothes were bought by his mom and therefore had her influence which made him wanna gag. There was one outfit though he had bought for himself. It was similar to the outfit Kirishima had brought for him on that trip that eventually got ruined. But there were similarities, like subtle white roses on the vest that went over a dark red button-up. No doubt it would match the outfit Kirishima bought, all of his clothes

were red. Not that it mattered.

Ugh.

Bakugou slipped into the outfit and put on his dress shoes. Gods, he hated how stiff these clothes felt, far too tight for such little elasticity. He tied his tie, making sure it was centered and even and flat. He sighed when he had no other reason to stall his arrival. He pocketed his phone and headed for the gym.

The decorated room was already full of people, the lights were dimmed and music was blasting. While many were still mingling on the outskirts, he could pick out quite a few faces on the dance floor, including the lovable redhead. He had stopped scanning the room at this point and his gaze was fixed on his person, spinning and giggling with the bakusquad and his girlfriend all bouncing beside him. These were the things Kirishima wanted to do, the things that gave him joy, and so while Bakugou hated these types of events, he was content to watch them from the sidelines. When Kirishima had been drowned by the crowd, Bakugou moved to get some punch, mostly for something to do since he hated how much sugar they put in it. He ran into Todoroki doing the same, but all they exchanged were nods before moving on. Bakugou found a place along the wall where he could see Kirishima again. How the hell did he have so much energy?? Bakugou took a sip of his drink. There was definitely alcohol in this. He sighed. He wouldn’t go back for seconds, but he’d slowly finish this cup off. He checked his watch and wondered when the big moment was supposed to happen. Bakugou thought back to those incessant ramblings from the past few days. 7:30. Eighteen more minutes.

At some point, Bakugou lost Kirishima again but was too lazy to go looking. He didn’t need a chaperone anyway. Who was Bakugou to be chasing him all night? He wondered if he’d have to watch them kiss... Maybe he would get a second drink. He was halfway through that cup when the lights changed. They all dimmed except for a spotlight in the middle of the crowd. Just like Kirishima had said, fake snowflakes started to fall as “I can’t help falling in love” played over the speakers. Cheesy. He called it. The dancers looked around confused at why the one spotlight didn’t seem to focus on any one couple. And then it hit Bakugou. He still couldn’t find Kirishima in the crowd. Bakugou pushed his way through the mass of people. Maybe he had gotten too distracted by one of the phone charger’s jokes to notice the song had started. Maybe he had run to the toilet at the wrong moment. He searched and searched until the song ended. Kirishima was not in the gym and neither was the girlfriend.

Where the hell had he gone?! After all that planning, and all that talking about all that planning… to just abandon it? No, something was wrong. Bakugou downed the last of his drink and exited the gym. Cold, brisk air hit him in an unexpectedly pleasant way. A few couples were mingling outside. A few couples including the girlfriend, but the person she was making out with was not Kirishima.

Bakugou stomped over and grabbed her by the shoulder, dislodging her mouth from whoever this fucker was.

“What the hell?!” She shrieked.

“That’s my fucking line. What about Kirishima?!” He yelled.

“Uhhhh I broke up with him,” she feigned a grimace.

“What the fuck?! Why!?!”“It’s high school prom. I wanted to get laid and he couldn’t stop talking about dancing and some song coming up,” she shrugged.

“Fuckin bitch. Go to fuckin hell,” he growled, then headed toward the dorms.

Bakugou was aware he was stomping through the empty building, but he didn’t care. It was dark too, the lights having shut off due to no motion activity. His steps were echoing off the tiled floors and mostly barren walls. But he wanted to be heard at this moment. He wanted the whole world to hear his fury. He reached their floor and noticed Kirishima’s light wasn’t on. Fuck, he better be in there. He started pounding on the door calling out his name with no response. Bakugou tried texting his phone and sure enough, the muffled text tone could barely be heard from within the room.

“Kirishima!!! I know you’re in there! Open the damn door now!!!” Bakugou barked. No response. He tried the handle. It wasn’t locked. So he pushed his way into the dark room, using his phone as a light. He let the door close behind him. His phone light was dim but it was enough to see Kirishima cross-legged, hunched over, face stuffed into a pillow, shaking.

“Go away,” he barely heard.

“Fuck no,” Bakugou walked over and plopped himself next to the upset red-head. “Talk to me,” he said gentler than either of them remembered he was capable.

“It hurts…”

“I know. It sucks.” Bakugou realized how much of a loss he always ended up at when Kirishima was this upset. “Do you want to play a game or watch a movie?”

“I don’t want to do anything. Maybe ever again. I tried so. Fucking. Hard. But no one fucking cares.”

“You …didn’t actually love her did you?” Bakugou almost whispered.

“I… fuck…probably not,” he raised his head and started to wipe his face, a box of tissues already at his side. “But I wanted to. I want it so badly. Why am I so unloveable??” Kirishima cried.

“You aren’t. She’s just too much of a dumbass to see it.”

“She and everyone else I’ve dated. Maybe I should just face the damn facts.”

“Pretty sure your ‘facts’ are just self-depreciating bullshit. You’re the best person I know. And I don’t fucking spout lies, even for you,” Bakugou said quieter and quieter.

“I wanted to make this great moment and all she wanted to do was sneak off to the bathroom.

She couldn’t wait twenty minutes before saying she’d find someone else. I should have just gone with her and stop trying to be so freaking romantic. Something is fucking wrong with me!” Kirishima was throwing his head back into the pillow, now hurt AND embarrassed.“Look, if she’s going to dump you for something so stupid, I’m glad it happened sooner than later. It’s just another sign that you weren’t right for each other.”

“No one is right for me.” Bakugou sighed. He was really hard to get through to in these situations. So he took a leap.

“Will you do me a favor?” Bakugou asked. That got Kirishima’s attention. He was pretty sure Bakugou had never said those words to anyone.

“What?”

Bakugou picked up his phone and fiddled with it for a second before sound started pouring through the speakers. Bakugou walked to where he knew Kirishima’s string lights plugged in. The room overflowed red. Kirishima recognized the song. Bakugou held out his hand.

“Dance with me.” Kirishima sat in shock. “You wanted to dance to this fucking cheesy, old-ass song, so let’s fucking do it!!” Bakugou barked impatiently. Kirishima, in a trance, stood up and took the outstretched hand. He wiped his tears with his other arm and sniffled. Bakugou put his hands around Kirishima’s neck and Kirishima fell into the blond, forehead on his shoulder and arms wrapped around Bakugou’s narrow waist. They rocked slowly to the words. Everything was so quiet, all they could focus on was the song and each other.

“I’m the fucking fool,” Kirishima whispered, referencing the lyrics. He had to admit, he felt better in this hold. He wasn’t lost in the ocean again like all the times before. He clung to a raft that let him drift slowly, peacefully through these deep waters.

“That’s okay,” he replied. And then even softer, “You’re my fucking fool,” Bakugou dared, fingers swimming in red locks soothingly. He can’t believe he was basically confessing. He wasn’t planning to confess ever. In this moment, he let himself believe his fantasy could be reality. Most of their class had noticed Bakugou’s preference for Kirishima over anyone else. Well, everyone but Kirishima. Fucking dumbass. Kirishima raised his head in shock and met crimson eyes. He was serious. He meant those words, or at least wanted to. Kirishima, for the first time, glanced at his lips, looking for more than words. Bakugou wet his lips, waiting. Kirishima crashed into the blond, lips meeting over and over, tongues daring to tie together. They were suddenly breathing hard, Kirishima walking them to the wall and pushing Bakugou into it. He kissed Bakugou like he’d been needing it for years. He kissed, nipped, and licked Bakugou hard into the surface he was pinned against. When he heard small gasps or sounds from the blond, his pants went tight.

“All she had to do—-mnnnh—was fckn—-dance,” Bakugou ground his own erection into Kirishima’s. That was by far the hottest feeling he’d felt from another person in his life. Sex with his girlfriends always kind of felt like work and like their hearts weren’t in it. But now, he was at full mast, straining against his dress pants, practically begging for more contact.

“Fuck that was hot,” Kirishima panted before diving back in, threading fingers through blond hair before clenching down and pulling. The surprised gasp only made his dick jump in his pants. “Fuck…Bakugou,” Kirishima kissed his way down his neck until he found a good spot to start nibbling and sucking.“Hah… Kiri—shima—…ah…” Bakugou tried to say something, but the words were getting lost. Between the hardness against him, the hands clawing at his hips, and the hot wet mouth searching for more and more of him… words were far too complicated to process right now. They wanted this. And they wanted it now.

“Fuck… Bakugou, how are you this fucking hot?” The deep gravelly voice was not helping Bakugou’s situation. He was getting lost in how his name sounded, how those curses were rolling freely out of those pink lips he’d always admired.

“F-for you…fuckin…dumbass—“. Bakugou huffed from all the physical stimulation. Kirishima stopped and looked at him seriously, brushing his hair back without realizing it.

“Really?” The hope in his voice reminded Bakugou of why they were there. Kirishima was just upset. He was using Bakugou as a rebound. He turned away this time when he talked.

“Really. But it’s not what you’ve ever wanted. I—,” he started to push Kirishima away.

“Are you kidding?” Kirishima had the audacity to laugh, then dive back onto that pale throat.

“Do you hear the noises you make?” He kissed his jaw. “Do you hear the arrogance in your voice even as I have you pinned you against the wall?” He kissed the muscles by his throat.

“Do you know I notice when you say you’ll stay 10 minutes and you stay 30? For me?” He kissed his collarbone. And then, lowest of all, “Did you know I've gotten off to you when I’m alone?” He whispered in the blond’s ear, and the fuse was lit. Bakugou jumped on Kirishima, literally, legs swinging around the taller one’s hips. Mouths were reunified, hot and wet, while Kirishima supported Bakugou’s weight with his hand under his thighs. Before finally picking him up, he let his erection tease at the underside of Bakugou’s balls through their pants. Small thrusts to poke at his intentions. Bakugou groaned.

“Bed,” he panted, his arms clinging to Kirishima’s back, claws digging in. Kirishima gave one last thrust before picking the blond up with ease he walked the few feet to the bed and plopped the blond on his back, taking a moment to enjoy his flushed face.

“No man should be this attractive,” he whispered with a soft touch.

“You gonna fuck me or what?” Bakugou tried to sound commanding, but his will was cracking.

“Fuuucckkk,” Kirishima groaned into his neck. It took a minute to unbutton all those stupid buttons, and it took all Kirishima’s strength not to tear the shirt clean off. Hand roamed over his pecs, down his ribs, and back around those lean hips. Fingers circled the bone before giving a playful yank. The pressure on their impossibly hard dicks was more than welcome. The sounds they made were proof of that.

“Too fuckin slow,” Bakugou was starting to sound desperate.

“Shh I’ll take care of you,” he said so tenderly, as if he weren’t working open both of their dress pants and disrobing the blond completely. God, even in the low red light, the body before him was perfect. “You’re perfect,” slipped out. He watched Bakugou’s dick twitch at the compliment. “You like that, huh,” he was back over him, whispering in his ear, working his own pants off. The moment their hard-ons touched, pained groans sounded from both of them. Fuck they were moving too slowly. At this point, they were going to blow by the first yank. So, of course, Kirishima teased harder. Let his finger drift close, barely ghosting Bakugou’s now weeping dick.

“Fuck,” Kirishima heard quietly.

“Imagine how you’ll sound stuffed fucking full.” Bakugou let out a strangled breath at the thought. It was time. Kirishima finally left the warmth of his newfound lover to fish out the lube. “Are you sure?” He asked.

“Fuck yes. Fucking fuck me right the fuck now,” Bakugou demanded. “Eijirou,” he added as an extra spur. It worked. Kirishima wasted no time working a finger in his tight hole. He would curl it to see if he could find a reaction. None yet. Guess he would have to try with two. Bakugou was stiffening under his touch, but it still wasn’t the spot. “More,” he breathed. Kirishima squirted more lube and slowly pushed in three, waiting for the blond to adjust to the stretch. He watched the pain fall from his face before moving.

“This okay?” Kiri whispered. “Katsuki?” He matched Bakugou’s previous tone.

“Fuuuu-…” was all Bakugou managed. Kirishima pumped a little faster, a little harder. Until he found the spot, and Bakugou jolted. If he thought Katsuki was hot before, he was absolutely mind-blown at the flushed, sweaty, panting, begging boy in front of him. “Fuckin, do it already,” he panted.

“Do what?” He started to pump harder into that spot, Bakugou wriggling at the sensation, gasping and gripping the sheets.

“No—not.. tha-at… your…f-fuckin… dick …f-fuckin…. Idiot…” he held back his orgasm the best he could, and Kirishima could see it on his face. Kirishima almost came at the whine he heard when he pulled his fingers out. And then again when he lined up his penis so the now slippery hole and slowly pushed the head in. He battled between the needs of his dick and the look of pain on his lover’s face.

“You okay?”

“One sec…” Bakugou breathed deeply and tried to relax. Kirishima took the time to litter small kisses across Bakugou’s chest. “Okay.” Kiri pushed in slowly. Damn he’d never felt such pleasure. He really hoped this wouldn’t completely ruin masturbation for him. But at least he has more material to work with. And maybe even a new partner. Slowly creeping inch by inch, he stuffed the blond full with his thick cock. He was so tempted to start moving, but the blond’s eyes made him wait. Until he said,

“What are you… waiting for…”

“Fuck, Katsuki,” he was back to kissing the hot man pinned under him, taking his full dick like a fucking champ. He was trying to go slow. A few times he’d ram in hard to hear the squeal beneath him, then slow back down. This can’t end, not yet. He kissed back to Bakugou’s neck and sucked another hickey while pounding into his ass. He felt Bakugou reach for his own election but swatted it away. He was in control here. He started biting lightly on the muscular shoulder when he finally gripped the other’s cock. Gods if he could record the sounds Katsuki was making…

“Fuck, Katsuki, you’re so fucking hot. I’m gonna cum so fucking hard. God, Katsuki… I fucking love you,” he breathed against Bakugou’s chest as he felt the heat pooling.

“Ei—eh—Eh—ei—ji—I—roouuuu,” Bakugou arched his back, Kirishima hitting the perfect spot and holding it. Cum spirted onto those tight abs over and over until he was finished. But Kirishima wasn’t. He rode the rest of Bakugou’s pulsing high, ramming as hard as he could over and over until he pulled Katsuki in tight, one last time.

“Fuuucckckkk..” he sighed. His hips bucked a little again, riding out the last of his orgasm.

“Fuck Katsuki,” he was collapsing against the blond, completely spent, letting his deflating dick slide out lazily. Kirishima slowly laid down on top of the blond, ignoring his cum covered stomach and they breathed together, attempting to regain any of their senses. Bakugou couldn’t find any words, even as his coherence was returning. He combed through that sweaty, still partially gelled hair. Kirishima breathed a few times before he dared to look at the other. He hoped and prayed to all the gods that he was still as happy as he was. But he wasn’t- but he wasn’t sad or mad… more, concerned.

“What’s wrong?” Kirishima asked. Now Bakugou did look worried. Hurt even?

“Was this just a rebound fuck?”

Kirishima blinked. A rebound happens when someone recently left a relationship (true), was in an emotionally charged situation (true), and is rushing into things with someone new (also true). But those relationships were usually with someone you don’t care about and that’s not true. His brain was processing this question remarkably slowly, so slowly that Bakugou’s face had fallen. Bakugou pushed Kirishima off him and climbed out of bed.

“Wait, wait, wait. Please wait, Bakugou,” Kirishima stammered. Bakugou stood but didn’t move away. “I’m sorry my brain is moving so slowly. This is just a lot to consider and I don’t want to hurt you by saying the wrong thing.”

“It’s not a complicated question.”

“Maybe for you! I-I-Before half an hour ago I didn’t even think you wanted to be in any kind of relationship! I still don’t, really, since we haven’t talked about it. But I want to talk about it! If you’ll stay…” Kirishima wanted to hug Bakugou so badly, but he kept himself planted on the bed. Bakugou balled his fist as his head dropped even lower. His voice sounded so defeated.

“Why now? Why has it taken three years AND me making the first move to figure out you might want this?” And then barely audible, “Want me?” Kirishima was on his feet and wrapping his arms around Bakugou in an instant. He was so stupid. He’d been hurting Bakugou for years and not even realizing it. All those times he talked about his dates… even tonight with his big plan… he’d really fucked this up.  

“I’m sorry. I’m sorry, I didn’t realize. Look, I… I’m an idiot, right? You say it all the time.” My fool. “I’ve always thought you were, um, hot.” His face was burning has he said it. Why was he getting embarrassed now after what they just did? He’d already let the L word slip too. Fuck. Kirishima shook his head and continued. He needs to focus on Bakugou. “And—and you’re my best friend. You’re incredible. You’re so inspiring. You work so hard and you’re the best at everything. I’ve never been at the top of any leaderboard. My grades are ass, and I ‘dress like a blind person,’ in your words. Maybe I’m really that dense but… I feel like the real question is, why would you want me?” 

At this, Bakugou spun around. His eyes were burning red and his frustration was clear.

“Exactly! You fucking moron! You’re all those things! You jumped off the roof with a blanket parachute not two months ago and broke your ankle like a MORON, and who took you to see recovery girl at 2 in the fucking morning? Me! Because you can be the stupidest, densest, worst dresser on the planet, and I’d still fucking—“ he stopped himself there. He took a breath. “You’re goddamn sunshine incarnate even if you wear those stupid crocks. We’re equals.”

“You’ve always found a way to make me feel better about myself,” Kirishima smiled softly. “Would you really want to try this with me? Dating? Even after I…”
“Kept me waiting? Beat my heart into the ground with all your talk about your girlfriends?” Bakugou couldn’t help but nail that one in a little harder, and it made Kirishima wince. Bakugou’s expression softened then. “Yes. I would.” It could have been 5 years or 10 years and Bakugou still wouldn’t let this chance slip through his fingers. 

“Really???” Kirishima’s eyes lit up.

“I just said yes!! Are you deaf now too?!” Bakugou yelled. Kirishima was elated though. He picked Bakugou up and spun them around. When he set him down, he brushed Bakugou’s hair aside ever so gently like he was memorizing the curve of his face.

“I’ll be the best boyfriend, okay? I’ll make sure you never doubt me again. I’ll bring you breakfast in bed.”

“What, burnt toast?”

“Maybe some flowers.”

“You can not pick flowers off of private property again.”

“A nice dinner.”

“Fast food does NOT count.”

“Man, do I already suck at this?”

“You’ve got the right idea. I make breakfast. You BUY flowers. And we go to the new sushi place downtown. Deal?”

“Shit, that’s way better,” Kirishima laughed.

“See? Your ideas are good. They just need a little work.”

“Good thing I have you,” Kirishima's smile was like seeing a sunset for the first time. Bakugou’d paint it if he were an artist. “Three years, huh?” he winked. 

“Shut up. Idiot.”

Your idiot.”

Bakugou stopped and thought about it. He had been strong for so long, pining for so long. He’d imagined this exact moment so many times, yet never believed he’d have it. But it was here. He could slide his fingers between Kirishima’s, and he wouldn’t be rejected. If anything, he’d get that lovesick grin (that gave him mad cuteness aggression) in return. He was dating Kirishima fucking Eijirou. That idiot was HIS. Of course, that news wouldn’t shock a single one of their friends. But it doesn’t matter how they got here. Bakugou would hold onto this dopey-eyed dork for as long as he could.

“Mine.”
