Work Text:
As a general rule of thumb, Shinsou avoids group outings like the plague, with very few exceptions. No exceptions, if he could help it, but since he’d made friends with some of the most outgoing and extroverted people on the planet it was inevitable that he’d be roped into a get-together or two every great once in a while.
After being a part of the same social circle for the better part of a decade with very few additions (hey, why fix what’s not broken? He’s happy with his friends, why would he need more?), most of his friends knew better than to even ask him to attend their frivolous hangouts, squad nights, or, god forbid, anything that could ever be considered a group bonding activity.
However, thanks to drunk Shinsou’s loud mouth and loose tongue, Kaminari held the secret to getting Shinsou to accept any invitation, no matter how much he would rather stay home and do literally anything else, up to including scrubbing the toilet or watching paint dry. The truth is, deep down, Shinsou Hitoshi was a weak, weak man.
“Bakugou will be there~” Kaminari’s sing-songy voice drifted through the speaker of his phone, woefully off key and pitchy but no less effective.
Shinsou’s alpha hindbrain had perked up immediately at the mention of the blonde omega's name, and no amount of deep sighs and glares at the phone in front of him could change the fact they he was now attending a Class A reunion dinner the night his first vacation in two years began.
Sure, he didn’t have any plans other than lounging around his apartment, playing with his cat and eating his weight in junk food until he felt sick, but having no plans was exactly what he’d been planning for when he put his request in for this vacation.
Except now he does have plans, and those plans involved getting dressed up to go to dinner with a group of loud, nosey pro-heroes and doing his best impression of an undercover operative as he tried to get close to Bakugou without making it too obvious that he’s pretty much had his eyes glued to the blond for about ten years and counting.
It’s a good thing Shinsou actually was an undercover operative, and an even better thing that pretending to be semi-friendly at best (and not pathetically lovesick) to Bakugou was practically his longest-running undercover mission, otherwise his nervousness at being caught might overshadow his excitement at seeing the omega of his dreams.
The thing is, Shinsou has been in love with Bakugou since the first time he’d laid eyes on the omega and smelled that perfect creme brulee scent that haunted many of the purple-haired alpha’s dreams and, ahem, waking fantasies.
Even though Shinsou had been doing what he does best at the time of their meeting (i.e. shit-talking and instigating), he had immediately noticed the loud, angry blond that was telling off his class and it felt sort of like the world was suddenly brighter and everything made sense… or something equally as sappy as that.
Yeah, he knows the whole “love at first sight” thing is criminally overdone, but it sounds a touch less pathetic than ‘a beautiful blonde omega insulted me and I got so hard in my standard-issue school uniform pants that I thought I might genuinely pass out from the blood rushing from my brain to my dick. And I sort of maybe have been riding that high for years now???’
So that’s how Shinsou found himself in the banquet room of an upscale restaurant feeling entirely underdressed in a pair of black jeans and a graphic t-shirt with a cartoon cat on it (admittedly, he hadn’t looked up the place before he came, otherwise he might have put a little more effort into his outfit) in search of a messy head of blond hair that was nowhere to be found.
“What the fuck, Kami?” Shinsou hissed through his teeth after grabbing the electric blond omega’s elbow and dragging him just outside the door of the room. Kaminari was obviously buzzed if his stumbling and high-pitched giggling was anything to go to.
“Awe, what’s wrong ‘Tosh? Can’t find your boy-toy?” Kaminari giggled, and Shinsou had to count to three in his head and remind himself that the man in front of him was one of his very best friends and it would be very unfortunate if he did anything to jeopardize that.
“You said he would fucking be here, that’s the only reason I came! And don’t call him that, he’s not my ‘boy-toy.’ Where the hell is he?” Shinsou said as calmly as possible, although his alpha wanted him to grab Kaminari and shake him as if the secret of Bakugou’s whereabouts might fall out of his mouth quicker that way.
“I don’t know, dude! Kiri and I talked to him last week and he said he’d be here! You know how he is, he hates these things just as much as you do, maybe even more. You guys are, like, made for each other. Why haven’t you told him you love him again?” Kaminari asked way too loudly.
Shinsou slapped his hand over the blond’s loud mouth and shot him a glare. “Stop being so damn loud, what if someone hears you!”
Kaminari slapped his hands away and rolled his eyes, settling his hands on his hips as he gave Shinsou an unamused look. “Relax, no one’s even around. Besides, would that really be so bad if people knew? The more people pushing you two together the better, I say. Ever notice how Bakugou doesn’t date either? Maybe he likes you back!”
“There’s a huge gap between ‘doesn’t date’ and ‘might like you back’ don’t you think? Besides, we hardly see each other, I sincerely doubt Bakugou even thinks of me unless I’m in his direct line of vision. Even then he’s only thinking about the best insults to throw at me.”
“Don’t act like the insults don’t get your engine going, ‘Tosh. I’ve heard enough of your dirty fantasies to last me a lifetime.” The omega wagged his eyebrows up and down at the alpha, whose reddening face contrasted harshly with his lavender hair.
“Whatever. I’m leaving, Kiri’s good to drive you home right?”
“Awe, don’t leave! You’re already here, might as well stay and have some fun. Todoroki’s putting all of our drinks on Endeavor’s credit card so it’s almost like an open bar if you think about it!”
The alpha didn’t even pretend to consider the offer before turning heel and throwing a monotone “pass” over his shoulder. He headed toward the exit of the restaurant, but was stopped short by a flash of green stepping in his path.
“Oh, Shinsou-kun! Are you heading out so soon?” Midoriya asked cheerfully.
“Uh, yeah, I’m not feeling it so I’m going home. Have fun though. I hear Todoroki’s buying everyone’s drinks so it should be a good time.” When Shinsou tried to step around Midoriya, the green-haired omega got into his way once more.
“Oh yea, Shouchan’s the best, isn’t he? Anyway, that’s why I’m out here! I was looking for someone to do me a quick favor and everyone in there is a little too tipsy. Would you mind?.”
Alarm bells rang in Shinsou’s head and a million excuses instantly sprang to mind. Under no circumstances did he want to get roped into helping Midoriya out with whatever it is he needed help with when he knew there was a seat on his lumpy couch and a bag of chips waiting for him at home. Besides, Midoriya’s “quick favors” were usually the exact opposite of quick.
“Sorry, Midoriya, I really have to get going. Maybe try someone else.” But the omega grabbed his elbow, holding him in place so he couldn’t leave.
“Wait! It’s just– Everyone else is sort of drunk, and I just thought maybe you’d be the best one to help me out! And, phew, I have had just one too many and I don’t think I can do it myself!”
Shinsou raised an eyebrow at green-haired boy in front of him, who appeared to be nothing but stone-cold sober. “Oh really? You don’t seem drunk–”
“Oh I am, trust me!” The omega said, nodding his head enthusiastically causing his green curls to fly wildly around his head. “You know me, I’m a lightweight! Anyway, it’s just– Well, Kacchan told me he’d be here tonight, and he’s not answering his phone, so I really need someone to go check on him. You don’t mind, do you Shinsou-kun?”
The alpha’s refusal died on his lips and his ears perked up. Midoriya wanted someone to go check on Bakugou? As in go to Bakugou’s house, where Bakugou lived, that sort of checking on Bakugou?
“I– I don’t know where he lives.” Shinsou protested weakly, trying his best to tamp down the alpha in the back of his head that was screaming at him to accept the offer, no matter how his rational brain tried telling him it was a bad idea.
“Oh, that’s no problem! I’ll text you all the information you need. Oh, and here, I have a spare key so you can just let yourself in.” The green-haired omega pulled his keys out of his pocket and Shinsou watched as scarred fingers retrieved an All Might painted key from his key ring before depositing it into his hand. “Thank you so much, I definitely owe you one!”
With that, the omega ran off, entering back into the banquet hall without so much as a glance back in Shinsou’s direction. What the actual fuck just happened?
The purple-haired alpha stood there dumbstruck until his phone buzzed in his back pocket. Pulling it out, he realized it was a message from Midoriya containing Bakugou’s address and a brief message thanking him for the favor with more smiley face emojis than was strictly necessary (none were necessary, but come on, this is Midoriya we’re talking about).
Shinsou only gave himself a moment to come to terms with the fact that this was actually happening before scrambling out of the front door and making his way to the train station embarrassingly quickly.
If the universe wanted to offer up this opportunity to Shinsou on a golden platter, well, who was he to deny it?
*
Bakugou lived in a very quiet part of town where Shinsou previously believed only Japan’s oldest citizens resided. His apartment had a lobby attendant who looked at him with narrowed eyes when he signed into the visitor book, as if he was trying to judge whether or not the man was a threat to the security of the place. Shinsou was sure he would have been booted from the premises if he hadn’t nervously blurted out “Hero Deku sent me, and look, I have a key!”
Now he was face to face with Bakugou’s door. Instead of immediately letting himself in he tried to knock a few times, still not entirely convinced that he wouldn’t be met with an explosion to the face if he just waltzed in unannounced, no matter what the intentions were or who sent him. However, there was no answer, leaving Shinsou no choice but to use the key.
Pushing the door open, Shinsou was immediately met with the smell of caramelized sugar and vanilla, which had his face flushing and his alpha internally howling. Bakugou always smelled good, even after a full day of fighting villains where any normal person would probably smell terrible, but this was a whole different level.
Something about the smell overrode his rational thoughts and he found himself quickly discarding his shoes in the genkan and allowing his nose to lead him to the source of the wonderful smell, which appeared to be a bedroom at the end of the hall.
The purple-haired alpha found himself standing in a neat bedroom, minimally decorated with dark wood tones with a few pieces of tasteful artwork hanging on the walls. The majority of the space was taken up by a rather large, comfortable looking bed, but it wasn’t the bed itself that had Shinsou’s mind blue-screening, it was what lay on top of it.
Oh fuck. In the middle of the bed, starkly contrasted against the black silk sheets, was Bakugou donning only a large t-shirt and a pair of tight black boxer briefs. He was curled in a ball with his knees pressed up as close to his chest as they could go, and he was surrounded by a pile of intricately woven blankets and what looked to be stray pieces of clothes, some of which Shinsou thought he’d seen some of their mutual friends wear before.
Bakugou didn’t ditch dinner just because he didn’t want to come, and he wasn’t in any sort of trouble; the blond omega in front of him was in heat. All of the puzzle pieces fell into pace as the realization dawned on him. Bakugou’s heat must have come unexpectedly, that’s why he didn’t show up and why Midoriya wasn’t aware of it.
Purple eyes roamed the length of the omega’s long pale legs, taking in every bit of exposed skin he hadn’t seen since stolen glances in the high school locker room. Bakugou looked so peaceful like this, his normally very expressive face relaxed as quiet snores sounded from him. It made Shinsou’s heart pang with affection, and his instincts were screaming omega, mine, protect.
Shinsou didn’t know how long he’d been standing there when the sleeping body stirred, jerking him out of his thoughts and causing panic to flare up in him. He thought of how bad this looked, and worried about how Bakugou might react to waking up in heat to an uninvited alpha looming over him. It was a death sentence for sure, and he wouldn’t even be able to blame the omega if he blasted first and asked questions later, but luckily the blond didn’t wake up.
Taking it as a sign, Shinsou gave one last longing look to the figure in the bed before he turned on his heel and walked toward the door as quietly as he could. All of his senses begged him to stay, but Shinsou wasn’t about to let himself turn into a creep over some stupid instincts.
A sleep-laced voice startled him and he whipped around to find Bakugou sitting up in his bed, forehead creased in confusion and sleepy eyes blinking blearily at him as if he wasn’t convinced he was actually awake. “Eyebags? Th’fuck are you doing here?”
Shinsou’s voice stuttered as he searched for the words that would make the whole situation. “Well– I– You– You didn’t show up to dinner.” He settled on, and he could have face-palmed at how stupid he sounded.
Bakugou snorted. “Yeah, I think it’s pretty fucking obvious why I didn’t show up. That doesn’t answer why the fuck you’re standing in my room like a damn creep. How the hell did you get in here, anyway?”
“I’m not a creep, I swear!” Shinsou denied, y’know, like a creep would. “Midoriya asked me to come check on you! He was worried when you didn’t answer his texts. He gave me his spare key!” The alpha rambled, fishing in his pocket for the All Might key and holding it up for the blond to see, hoping that the piece of metal was evidence enough that he hadn’t broken into the blond’s apartment for nefarious purposes.
The explosive boy narrowed his eyes at the key that dangled in the air between them. He fished for his phone off the night stand and looked at it for a brief moment, before red eyes flicked up to inspect the alpha instead. “Izuku sent you, huh?”
Shinsou nodded in confirmation. “Yes, he did.” When the blond said nothing further, the alpha continued. “He said he was worried about you but had too many drinks to come check on you himself, so he asked me to come instead. But I see that you’re fine, so I’ll just be going now. Have fun– I mean– anyway, bye now.” Smooth, Hitoshi.
Entirely embarrassed about the whole exchange, Shinsou moved to leave. “Wait!” Purple eyes flicked toward the omega at his sudden outburst. “Don’t go.”
Shinsou looked at the boy in confusion. “You… don’t want me to go?” He asked, unsure.
“You don’t have to go. I mean, if you don’t want to.” The blond mumbled, a slight pink tinge to his cheeks. Shinsou didn’t know what to say. It almost felt like a trap, but he wasn’t sure what the purpose of it was. He must have taken too long to respond because the blond’s face morphed into anger. “If it’s a fucking chore you can just go!” He snapped.
“No! I mean, it’s not a chore, I’m just… confused? I’m not sure what you’re asking me.”
“I’m not asking you anything, just stay if you want to fucking hang out, or don’t, I don’t care.” The omega grumbled, crossing his arms over his chest and glowering at the wall beside him. “It’s– nice to have company, I guess.”
Shinsou knew it was a bad idea, but if asked he would blame his response on the absolutely delectable smell of sugar swirling in the air that caused him to lose all rational thought. “I’ll stay. I want to stay.” He took a few steps toward the bed, stopping just a few inches from it, waiting for the blond’s instruction.
“Well? What are you waiting for?” The omega snapped, but when Shinsou lifted his knee to crawl into the bed, the blond threw his hands up. “Stop, what the fuck do you think you’re doing?”
Shinsou recoiled, snapping his body up ramrod straight as a wave of nausea washed over him. Of course he’d misunderstood what Bakugou was asking. Of course he’d never want Shinsou in his nest, especially when he was in heat. What a fucking idiot, he’s gone and ruined everything–
“You’re not wearing jeans in my damn bed! And the fact that you thought it was okay to wear that ugly-ass shirt within a five mile radius of me, much less into my damn apartment, shows that you have no sense of self preservation or style.” He yelled, looking at Shinsou’s shirt in disgust.
The alpha visibly relaxed, the air finally returning to his lungs. The omega was looking at him expectantly, an eyebrow raised in what seemed like a challenge. “So? Take them off.” Shinsou’s face flushed red, but he pulled the shirt over his head and slid his jeans down his legs, awkwardly kicking them off when they got stuck around his feet. After a moment of consideration, he toed his mismatched socks off as well.
Shinsou was by no means ashamed of his body, quite the opposite actually, and he didn’t consider himself someone who thrived on the approval of others, but he found himself puffing up when Bakugou’s eyes roamed the length of his body with something akin to approval on his face.
After the omega deemed him sufficiently ready, he beckoned the alpha closer, and Shinsou climbed in gingerly, careful not to disturb the carefully crafted walls of the nest. He laid on his back, staring at the ceiling, his mind a whirlwind of thoughts, all of which boiled down to holy fuck I’m in Bakugou Katsuki’s fucking nest.
Bakugou shifted next to him, his warm arm brushing up against the alpha’s and sending a jolt of electricity through the alpha’s body, straight to his dick which began hardening in his pants as the reality of the situation set in.
He was in Bakugou’s bed. Bakugou, who he’d been in love with for so long and had many dirty dreams about, many of which started just like this. Bakugou, who was currently in heat, which was amplifying his sweet smell to maddening levels that had his usually tame alpha scratching at the walls of his brain. All of this was the perfect storm for the most unfortunately timed boner, and Shinsou prayed that it was dark enough that Bakugou wouldn’t notice–
–which might have worked if Bakugou hadn’t turned toward him and pressed his heat-warmed body fully against him, letting his head rest on the alpha’s bicep and throwing his leg over him. Right on top of his boner. Shinsou froze.
Bakugou’s head popped up and red eyes stared at Shinsou in anger or surprise or whatever it was that caused his eyebrows to jump up into his hairline, Shinsou couldn’t tell exactly because he refused to meet the omega’s eyes. “Are you hard right now?” He asked incredulously.
“Fuck, I’m sorry, I didn’t mean– It’s just you smell so good and– I’m so sorry. I can go! I’ll go.” Shinsou rambled, but when he sat up he was pulled back down, pinned to the mattress by a smaller, muscular body before he could even comprehend what was happening.
“Calm the fuck down, shitty alpha! I didn’t ask you to leave now did I?” The small omega growled, pushing his forearm into the alpha’s chest without regard, but that’s not what had Shinsou breathless.
No, Shinsou’s breath was stolen away by the fact that Bakugou was now straddling him, long t-shirt riding up to reveal milky white thighs encasing the alpha’s hips. Even worse for Shinsou’s ability to think was the pressure of Bakugou’s ass pushing against his dick.
The blond was leaning forward, his weight pressing into Shinsou’s sternum as he stared into the alpha’s wide purple eyes. “Now, are you going to be good and stay here for me?” Unable to form any coherent words, Shinsou nodded, heart beating against his ribcage. The omega’s mouth twisted into a feral grin. “Good boy.”
With that, soft lips crushed into his own slightly chapped ones, moving against them frantically as warm hands rested on his chest. It took Shinsou a moment for his brain to catch up to the new development, but soon his own lips matched Bakugou’s in earnest, strong arms wrapping around the omega’s torso and pressing him even further into the alpha’s chest.
Any amount of time could have passed as he clung to the warm body on top of him; seconds, minutes, hours, Shinsou had no idea. If you told him the entire world had ended while he’d been kissing this beautiful omega he would have believed it, because anything outside of the feeling of the blond’s lips on his ceased to exist in that moment.
Sharp teeth bit into his bottom lip harshly before the omega pulled away, both of them panting heavily into the quiet room. “So, alpha, you gonna fuck me or what?” Bakugou purred, leaning back on his heels and no doubt feeling Shinsou’s very obvious interest in doing just that pressing into his ass.
“Yes, please– I want to so bad, you have no fucking idea.” Shinsou responded, no regard for how desperate he sounded. He was desperate, his dick was so hard it felt like it might fall off. And hell, if Bakugou was going to offer there was no chance in hell he was going to decline.
Bakugou smirked at the man’s blatant begging before grabbing the hem of his shirt and pulling it off in one swift motion, leaving him only in his boxers. Fuck, he was so gorgeous, Shinsou wanted nothing more than to lean forward and take advantage of the omega’s newly exposed chest, but the blond was moving before he had the chance.
Shinsou watched as the omega came face to face with his pelvis, his red eyes staring directly into his own purple ones as he leaned forward and mouthed at Shinsou’s cock through his boxers.
Hello, God? It’s me, Hitoshi. I’m ready when you are, all my dreams have been fulfilled and I can die happy now.
Shinsou groaned at the feeling of the hot mouth licking at the head of his cock through the thin fabric of his boxers. He watched Bakugou work as the blond teased and stroked him until the alpha was panting like a dog underneath him.
Rough fingers hooked into his waistband and tugged his boxers down, his cock springing up and only just missing hitting the blond in the chin.
“Damn, Eyebags, who would have known you were hiding this in your pants?” Bakugou said, giving an appreciative look when he wrapped his fingers around the alpha’s dick with his palm leaving several inches uncovered, fingertips only just touching if he squeezed (not that Shinsou minded the squeeze, if the moan that was punched out of him when he did was anything to go by).
Shinsou breathed a laugh that quickly turned into a breathy moan when the omega leaned forward and kitten licked the bead of precum that had gathered at the head before sucking the whole tip into his mouth. “You– fuck– you know, I’ve been told I have big dick energy so I don’t know why you’re surprised.” Shinsou joked.
The look the blond gave him when he pulled off was nothing short of unimpressed. “You’ve been told wrong. Now am I going to suck your dick or are you going to make stupid ass jokes? Because I’m telling you right now it won’t be both.”
Shinsou’s reply was immediate. “Dick sucking, please. Definitely dick sucking.”
“That’s what I fucking thought. Now lay there and shut up before I change my mind.”
The blond got to work once more, sucking and bobbing, taking in more length each time his head went down until Shinsou felt the tip hit the back of the omega’s throat. He felt Bakugou swallow around him eliciting an embarrassingly loud moan, but the blond only stilled to take a few deep breaths he continued trying to get as much of the alpha’s dick in his throat as possible.
Fuck, did Bakugou have to be good at absolutely everything? Shinsou felt like a pillow princess, laying here while Bakugou took care of everything else, which was definitely not his usual m.o. He was used to being the one in control, the one who took care of his partners, but Bakugou seemed to find joy in being the one in charge, and Shinsou would be a liar if he said he didn’t want to give it all up to him anyway.
Shinsou let out a surprised gasp when he felt the last inch of his dick slip into the warm wet heat what was Bakugou Katsuki’s perfect mouth (fuck, how was this even real? Is he even sure it is? Maybe he got into an accident on the way here and this was his own personal heaven).
Bakugou met his eyes, victory burning behind blown pupils and lips squeezing around the base of his length, which would have probably been one of the blond’s signature smirks if his pink lips weren’t currently stretched to their limit. Now that he’d apparently achieved his goal of deepthroating the alpha, Bakugou began blowing him in earnest, bobbing and sucking and running his tongue on the underside of his dick which never failed to reduce the alpha to a puddle.
“Fuck, so fucking good– shit, Bakugou please–” Shinsou was reduced to a rambling mess, not even sure what he was saying as his blood rushed in his ears. Probably just a mess of “fuck” and “please” and a bunch of incoherent whines he was sure he was going to hear about later.
Shinsou choked on a moan when the blond whined around his dick, the vibrations sending shockwaves throughout his body. His eyes, which had fallen shut, snapped open and he stared in awe down at the omega who had shucked his boxers and was currently working his own dick.
The sight nearly pushed the alpha over the edge, knot threatening to expand behind the blond’s perfect teeth. “Fuck– you gotta stop or I’m going to cum before I have the chance to fuck you.” At that, Bakugou popped off and gave the head one last teasing lick.
Bakugou crawled back up his body, stopping every once in a while to suck deep purple marks into the alpha’s chest like he was trying to brand him, before capturing Shinsou’s lips in a kiss once more. The alpha didn’t care that he could taste himself on the blond’s lips, in fact he relished being the one lucky enough to lick inside the omega’s sweet mouth regardless of what he tasted like.
Straddling the alpha’s hips, the blonde reached back and grabbed the alpha’s dick, giving it a few soft pulls before lifting himself up and lining it up with his entrance. Shinsou’s hands found the omega’s hips, squeezing them softly but not doing anything to control the movement. Slowly, Bakugou lowered himself down, both of them letting out tandem groans when the tip slipped in.
Fuck, Bakugou was so wet and warm and tight. It took everything in Shinsou not to buck his hips up and fully sheath himself in the omega who was lowering himself down painstakingly slowly as he took each inch.
It felt so good, better than anything the alpha had felt before. Sure, he’d had flings and one night stands, even going as far as to date this one beta for a few months (which didn’t work out for obvious reasons; turns out people don’t like when you’ve been in love with the same person for years and that person isn’t them), so he was far from a virgin, but nothing else compared to what he was feeling right now. He could feel his knot already beginning to swell just from the feeling of being not even halfway in.
Once Bakugou was fully seated he stilled his hips, head thrown back and eyes squeezed shut as he breathed deeply, adjusting to the alpha’s size.
“Fuck, you feel fucking huge.” The blonde groaned, sounding like the breath had been knocked out of him. He rocked his hips back and forth experimentally, but even the small amount of movement was enough to cause Shinsou to see stars.
The alpha only had a moment to panic before his vision whited out and he came deep inside the omega, knot fully popping and locking the two together. His eyes were screwed shut as he pulsed inside the tight heat, hips twitching as he came down from his high.
The weight of what he’d just done came crashing down, and embarrassment flooded him. After several long moments the alpha reluctantly peaked his eyes open, not wanting to see the blond’s reaction. He was met with the sight of a slack jawed, wide-eyed Bakugou staring down at him. “Did you just fucking come?” He exclaimed, sounding more shocked than angry.
Wow, way to go and ruin everything, Shinsou. He’ll definitely want to sleep with you again after this stellar performance! Shinsou grimaced, nodding solemnly in response.
“Wow, you really are fucking pathetic, huh?” Bakugou teased meanly, recovering from his shock and grinning wickedly down at the red-faced alpha below him. Shinsou’s spent dick twitched inside of him causing the omega to throw his head back and laugh. “What, you like when I’m mean to you too?”
Shinsou shrugged, and tried to sound as nonchalant as possible to play off his embarrassment at the whole situation. “What can I say? You make me a little pathetic.” He flashed a grin when he felt the omega’s walls clench around him as he chuckled at the alpha’s response, all tension breaking immediately.
“What the fuck are you smiling about, Eye Bags? I wouldn’t look so proud if I were you, I didn’t even get to cum. What kind of shitty alpha doesn’t make an omega in heat cum before they pop their stupid knot!”
Shinsou’s smile faltered. “Fuck, I know. I’ll make it up to you, I swear.” His knot finally deflated enough for his still half-hard dick to slip out, but Bakugou didn’t move from where he was still perched on top of the alpha.
“Oh, and how do you plan to do that?” The blonde purred, voice dropping low and seductive. “How about I put a cock ring on you and fuck you without letting you come, huh? Sounds fair to me.”
Shinsou’s jaw dropped slightly at the change in the omega’s tone before he nodded his head enthusiastically. “Yes, hell yes, anything you want.” He breathed out.
Bakugou’s face changed abruptly. “What– really? You’d really let me do that?”
Shinsou’s hands squeezed around the blond’s hips, thumbs moving back and forth over the omega’s hip bones. “I would literally beg you to fucking do that, shit.”
A smile overtook the blonde’s face; not a smirk, but a genuine smile that stole Shinsou’s breath away. “You know, most alphas would throw a fucking fit if anyone suggested anything like that.”
“Most alphas are fucking stupid then. I’ll take anything you’re willing to give me– that includes your dick.” Shinsou grabbed the blonde omega’s thighs before flipping them over, Bakugou’s back now pressed firmly into the mattress as he loomed over top of him. “We’ll call it an I-O-U for later. For now, let me take care of you instead.”
Shinsou leaned into the omega’s neck, inhaling his sweet scent before licking over his scent gland. He nipped and licked at the blond’s neck, drinking in every moan and gasp as he traveled down to the omega’s chest. He took one of Bakugou’s nipples between his lips and the other between the tips of his finger, switching until both were puffy and red.
He continued trailing down until he was laying between the omega’s legs. He took a moment to appreciate the view, from the neatly trimmed blonde hair at the top, to the cock that stood proud, leaking from the tip (bigger than other omega’s he’d seen, but still much smaller than his own), to the hole glistening with a mixture of slick and his own cum that the alpha wanted nothing more than to taste.
“Are you going to stare at me all day or fucking- hnng, shit!” Shinsou didn’t give Bakugou a chance to continue his complaint before he dove in, licking and sucking at the omega’s puckered hole like a man starved.
Bakugou tasted exquisite, better than any meal Shinsou had ever had and he was willing to put money on the fact that he would never taste anything better. It wasn’t like they described it in the stories, no, it wasn’t sweet like honey or whatever else they liked to pretend; it tasted like pure sex, completely and uniquely Bakugou, and Shinsou knew for as long as he lived he’d never tire of it.
The blond squirmed beneath him, panting breaths and moans filling the room. Shinsou pointed his tongue, pushing it past the tight ring of muscle and drinking the omega’s slick right from the source.
It didn’t take long for the omega to become a moaning mess under him, fingers clenching the sheets at his sides. Shinsou pushed two fingers in past his tongue, fucking them in and out until the blond was loose enough for a third. He then curled his fingers, searching for the bundle of nerves he knew would drive the omega crazy.
He knew he’d found it when the omega moaned wantonly, and he zeroed in on that spot, pushing against it with every thrust of his long fingers. “Fuck– Shinsou, please, don’t stop. I’m gonna fucking come, I–” Bakugou cut himself off with a moan, tossing his head back as his walls clenched and his dick spurted his release.
Shinsou’s fingers didn’t let up, even when the omega gasped and pushed weakly against his hand. “You have one more for me, don’t you baby?” Shinsou said sweetly, fingers maintaining a steady pace and curling in a way that had the omega crying out. “Such a perfect omega, you can do it, cum for me baby.” He leaned down and wrapped his lips around the omega’s dick, flicking the tip with his tongue before bobbing his head in time with his flingers.
Bakugou’s back bowed and his hips bucked wildly, only held in place by Shinsou’s big hand pushing down on his abdomen. It only took a few more moments for the omega to come a second time. With one final cry the omega snapped, walls clenching as he squirted around the alpha’s fingers. Shinsou fucked him through his second orgasm, gradually slowing as the omega whimpered beneath him.
Pulling his fingers out, Shinsou watched in awe as the omega’s hole clenched around nothing. He shoved his fingers in his mouth, licking up the omega’s slick greedily while rutting against the bed, his own dick trapped between his abdomen and the sheets.
Fingers curled in his hair and pulled harshly, giving the alpha no choice but to follow where Bakugou tugged him up, kissing him deeply. “Get up here and fuck me, now.” The omega growled.
“No, it’s okay, I’m paying you back for–”
Bakugou cut him off. “You just ate your own cum out of my ass and made me cum twice, you’ve more than made up for earlier. Now fuck me, you coward!”
He didn’t have to ask twice. Shinsou lined up with Bakugou’s slick hole, pushing forward into the warmth. Instead of setting a quick pace, he slowly thrusted in and out, savoring every drag of the omega’s walls around him, still so perfectly tight even after two orgasms.
His head fell forward, forehead resting in the crook of the omega’s neck as he drunk in the omega’s scent. A hand curled into the hair at the base of his neck, and Bakugou’s neck vibrated with soft whimpers and moans as Shinsou slowly worked to his second orgasm that evening.
“Please, Shinsou– Hitoshi– I need your knot, please give it to me.” The omega cried, hips coming down to meet each of the alpha’s slow thrusts. Shinsou’s knot began to swell, hitting the blond’s rim before it pushed inside, knot swelling as he released into the omega with a soft moan.
The alpha continued to move his hips as he came down from his release, knot keeping him from and real movement. After a moment, Shinsou lifted his head to look at Bakugou, whose eyes were glassy and cheeks tear-streaked. He ducked his head down, kissing the omega softly before gently switching their positions so Bakugou was resting on his chest, still locked inside of him.
“That was–” He cut himself off, not having the words to describe the feeling in his chest.
“I know.” Bakugou responded, and even without words they both understood each other. Shinsou smiled to the ceiling, completely overwhelmed with the events of the night. A rumble began in his chest, and Shinsou didn’t even try to stop it. Bakugou returned it, his own contented purr filling the otherwise silent room as they laid there together.

“Damn, I’ll never hear the end of this from Izuku.” Bakugou grumbled from where he laid on Shinsou’s chest after they cleaned up and changed the sheets.
“What? Why?”
“Izuku didn’t text me about my heat.” Bakugou stated as if that explained everything.
“What do you mean he didn’t text you? He told me you weren’t replying to his messages, that’s why I had to come here and check on you. He was too drunk to do it himself.”
Bakugou snorted a laugh. “He didn’t text me, or call me either, for that matter. The bastard knew I was in heat and sent you here anyway, get it? What, you think we’ve been friends for twenty years and run a whole ass agency together and he still wouldn’t know when I’m out on heat leave?”
“Wha– but why would he do that?” Shinsou asked, genuinely confused.
“Oh my god, I’m fucking an idiot. The nosey bitch knows I’ve been interested in you, and he must have somehow known you were interested too and sent you here so we could figure it all out.” Bakugou explained. “And despite how much I hate him sticking his nose into my business, I trust he wouldn’t butt into this unless he was absolutely sure, so when I saw his text I decided to go for it.”
Shinsou groaned, slapping a palm to his forehead. “Fuck, that means I owe Denki too. Izuku must have overheard him teasing me about you. Wait– what do you mean you saw his text message? I thought you said he didn’t text you.”
“No, I said he didn’t text me about my heat.” Baugou grabbed his phone, unlocking it and pulling up a text thread labeled Dumb Deku, and near the bottom of the screen there was a single text message: ‘Have fun!’ with a purple heart emoji.
So Izuku had made the whole thing up just to get them together. Shinsou didn’t even have the heart to be annoyed at the green-haired omega for tricking him, not when everything had turned out so perfectly. Not when he was laying here with the omega he’d been pining over since high school; definitely not when he’d just fucked said omega twice, with promises of repeating it in the future.
“Oi! I can smell your horny ass from here, what the fuck are you thinking about?” Bakugou snapped, slapping his hand against the alpha’s chest to break him out of his thoughts.
Shinsou smiled sheepishly. “I just can’t believe this is real and not some freakishly vivid dream.”
Bakugou rolled his eyes at the alpha. “Don’t start getting sappy on me. Now come on, let’s get some sleep. My heat isn’t nearly over and we’re going to need rest if you’re going to keep up with me.”
And fuck, Hitoshi could never say no to that.
