This is just a little Bakugou/Sero omega verse fic I felt like writing. I was in the mood for rare pair and thought omega Bakugou and Beta Sero would be a nice change of pace from what I've been writing lately. Anyway, enjoy!
"That's no fair! How come Sero never has to help" Mina whined as Bakugou set her to peeling and chopping up the vegetables.
Bakugou glanced up from where he was stirring the large pot.
"Yeah, that's right," Kaminari chimed in. "You always make us help out if we want to eat but you just let Sero sit there and do nothing and then you feed him anyway."
Sero blinked, Bakugou did regularly feed him even if he hadn't actually helped out with the cooking.
He glanced at the blonde, only to find him red in the face and spluttering.
"Fine!" Bakugou roared, "No food for any of you!"
"What, no! I didn't say anything" Kirishima cried at the unfairness as Bakugou waved the wooden spoon around, shouting until they ran out of the kitchen arms trying to shield their heads.
"Why'd you have to say something to Bakugou for?" Sero grumbled, "now none of us will get to eat his cooking."
"I was just trying to point out a fact" Mina huffed looking forlorn.
"He was making katsudon as well, you know how much I like Bakugou's katsudon" Kirishima complained as he dropped down onto the couch.
"Well, it isn't fair Sero never has to help but Bakugou still feeds him" Kaminari said.
Kirishima rolled his eyes, "it's an omega thing."
"What?" Kaminari asked disbelievingly as Sero's eyes popped open in surprise.
Kirishima shrugged, "he's never said anything to me, but I kinda got the impression that he likes you, bro."
Sero coughed, choking on his spit as he tried to swallow.
Mina looked thoughtful, "that does kinda make sense actually."
"No, it doesn't, Bakugou's an omega, he'd go for a big strong alpha like Todoroki" Kaminari argued.
"Just because you're an omega who wants to go for a big strong alpha like Todoroki, doesn't mean that's how Bakugou feels" Mina laughed.
Meanwhile Sero just sat there watching the conversation like it was something out of the twilight zone. There was no way that Bakugou liked him. Bakugou was the most sort after omega in the whole school. He got a confession nearly every week. He was strong and smart and would be a kick arse hero one day. He wouldn't like someone as plain and ordinary as himself.
"There is no way that Bakugou likes me" he croaked.
Kirishima just smiled and shrugged, fixing the dark-haired teen with a knowing look.
They moved on to talking about other things, until they were interrupted 20 minutes later by Bakugou as he carried out five steaming bowls on a tray.
Mina squealed so loud Sero felt his ears start ringing.
"Aw thank you Bakubabe, you do love us!"
"Tch" Bakugou grumbled as he handed out the bowls before sitting down next to Sero and starting to eat. He glanced over at Bakugou to thank him for the food only to find the blonde already looking at him. Bakugou glanced away and Sero wasn't sure if it was his imagination after their conversation earlier, but he thought Bakugou's cheeks looked a little pink.
Over the next few weeks, he started paying more attention.
"Bakugou, come and sit with me" Mina cried, patting the seat next to her as the class gathered round to watch a movie together.
"In your fucking dreams" Bakugou grumbled, taking a seat on the floor at Sero's feet instead, where he gradually moved to lean against his leg throughout the course of the movie. Sero glanced around and found Kirishima smirking at him; the redhead winked before focusing back on the movie. Sero wasn't sure what to do so he tried to relax and not focus on the gorgeous omega who was currently rubbing his scent gland on the material of his pants right near his knee. He caught a whiff of Bakugou's delicious green apple and caramel scent and had to bite back a groan. It was harder for beta's to recognise scents, their noses not as attuned but they could if they tried and that was definitely Bakugou he was smelling right now.
Did the omega know what he was doing? He had to, Sero thought, there's no way you could accidentally rub the back of your neck on someone. That meant the omega was trying to scent him. It was subtle but for any sharp-nosed omega Bakugou's scent would be very obvious on the beta. Something hit the side of his arm, knocking him from his thoughts and he looked down to find Bakugou handing him a bowl of popcorn, a fierce scowl on his face.
"Thank you" he whispered, but Bakugou had already turned away.
"Here fucker" Bakugou growled as Sero was hit in the face with a flying object. He looked down to find a jumbo packet of his favourite kind of chips laying on the floor in front of him. He blinked up at the scowling blonde.
"Did you get my favourite chips?" Sero asked non-plussed.
"For you, you idiot. They were on sale."
"He paid full price for them and searched the whole store until he found the big packet" Kirishima grinned unrepentantly from Bakugou's side, hardening just before a large explosion went off by his head.
"You lying fuck!" Bakugou yelled before storming toward the kitchen to put his own groceries away.
"Thank you!" Sero called out to the retreating back.
"Please! PLEASE! Bakugou!" I really need your help on this test" Kaminari cried dramatically as they walked back to their dorms.
"Fuck no, I already have plans to go to the gym tonight."
"You can go to the gym anytime, but if I don't pass this test my parents are going to kill me."
"Tch, maybe you should've spent more time studying then playing video games all the time."
Kaminari looked tearful, but Sero could tell he was just putting it on. "I know, and I promise next time I will."
Bakugou just shook his head, like he didn't believe a word coming out of Kaminari's mouth, which was fair.
"I could really use a study session as well" Mina spoke up as they made their way inside, gathering in the kitchen for a snack.
Bakugou scoffed as he bit into an apple.
"We could make it a group study session!" Kirishima said excitedly, grinning from ear to ear. "Sero was saying to me earlier he needed to revise, and I know I need to."
Bakugou's eyes flicked to him for a moment, and he did his best to look like he knew what Kirishima was talking about.
"Ugh, fine! You better fucking bring your notes, I'm not doing it all for you."
Sero couldn't help the grin that broke out on his face as Kirishima, Mina and Kaminari all started cheering.
"Well, what are you waiting for" Bakugou shouted, "go get your shit! Let's do this."
All four scrambled off to get everything they needed with an unspoken agreement to meet up in Kirishima's room, like they usually did when studying.
Sero grinned from his place on the floor as he watched Mina wipe the floor with Kirishima during Mario Kart.
"Suck it" the pink haired girl squealed as she jumped on Kirishima and pushed him to the ground.
Kirishima laughed good naturedly, waving the controller around.
"Here, Bakugou, you want a go?"
"Fuck no," the blonde grumbled from his place curled up on Sero's bed. "Give it to Sero, he hasn't had a turn yet."
He grabbed the controller Kirishima threw at him, feeling warm all over.
Bang! Bang! Bang!
Sero dragged himself from his bed, cursing whoever was knocking at his door so early on a Sunday morning.
He swung the door open, expecting Mina or Kaminari but instead he found furious red eyes and a shock of blonde hair.
"Ba-Bakugou, what's up man?" Sero asked, clearing his throat as his voice croaked.
"Can I have some clothes, blanket, anything. Heats coming up" Bakugou's cheeks pinked slightly, but he didn't look away.
"Ah, yeah of course. Just give me a second."
Sero turned back around, closing his door slightly as he grabbed a hoodie and shirt as well as a blanket that he kept in his hammock. He rubbed them liberally on his neck and wrists, spreading his light scent of the items. He wanted Bakugou to think of him while he was in heat.
He walked back out, handing the things to Bakugou, who clutched them tightly in his arms.
"Thanks."
"Do you need anything else?" Sero asked, the urge to provide for the omega nearly overwhelming.
Bakugou paused for a moment, opened his mouth and then closed it again before finally shaking his head no.
"I'll see you in a few days."
"Alright" Sero said quietly, watching as the blonde walked away.
A few days later when Bakugou walked into the common room wrapped in Sero's hoodie and looking like he just got out of the shower, Sero could no longer deny it.
"I think you may be right" Sero said as he dropped down next to Kirishima and Kaminari on the lounge.
"Right about what?" Kirishima asked with a small grin that let Sero know the red head knew exactly what he was talking about.
"Right about Bakugou" Sero huffed. "I-I think he might be trying to court me."
"No way!" Kaminari squealed from Kirishima's other side.
"I think so too!" Kirishima crowed. "You weren't getting it, that's why I had to say something the other week."
Sero could have hit himself for being so stupid. It was obvious the omega was trying to get his attention and he'd missed it all.
He let out a loud groan. "What do I do now?"
"Well," Kirishima said seriously "do you feel the same way?"
"Of course, I do" Sero sighed. "I mean, how could I not, its Bakugou. He's loud and rude but also surprisingly thoughtful and caring. He's so smart and wicked strong and he has so much passion and drive. I don't know what on earth he sees in me" he finished quietly.
"Hey" Kaminari squawked, "don't talk about yourself like that. You are amazing and anyone would be lucky to have you."
Kirishima nodded, "he's right, bro."
"But I'm just a beta, he could have literally anyone."
"But he wants you. Bakugou would never be with someone he didn't really care about and respect. It's just not him."
Sero nodded, that was true.
"I'm going to court him back" Sero nodded determinedly.
Kirishima clapped him on the back, "good luck bro!"
Sero had a feeling he was going to need it.
He sweated over it for days, unsure where to start or what to do. He began avoiding Bakugou feeling bad that the omega was going to so much trouble for him and he could think of hardly anything to do in return. He'd even resorted to speaking to Izuku, Bakugou's oldest friend. He did his best to ignore the hurt look Bakugou sent him when he moved away from the blonde at the last movie night, instead sitting next to Izuku, claiming his spot was too cramped.
"Do you fuckers still need help studying for our test?" Bakugou asked the next day at lunch. "Come to Kirishima's tonight and we can revise."
"Yes!" Kaminari said, while Mina and Kirishima nodded happily.
"I can't make it, sorry" Sero said as he shoved a rice ball into his mouth, purposefully not looking up to meet Bakugou's furious glare.
"Why the fuck not?" Bakugou growled.
"Got other plans" Sero said simply. Like going shopping to try to find you a courting present he thought as his stomach twisted in a mixture of excitement and nerves.
"Ooh" Mina teased, "who are you meeting up with?"
His eyes snapped to Bakugou, as he spluttered "no one!"
He couldn't have looked more guilty if he'd tried, which was ridiculous because he wasn't actually meeting with anyone, well at least not in the way they were clearly thinking.
Mina leaned over and pinched his cheek and Sero realised he was blushing.
Ugh.
Bakugou looked down at his food, his eyebrows furrowing and Sero longed to comfort him, he stretched out a hand but before he could reach his target someone clapped him on the back, interrupting the movement.
He snatched his hand back and swung around to find Izuku standing there, smile so wide his cheeks were appled.
"Are we still on for this afternoon?" Izuku asked.
Sero ran a hand through his hair and bit back a groan.
"Yeah, yeah. We can meet after class" Sero said quietly.
Izuku nodded before turning and greeting everyone at the table.
"Well, I better get going. See you later Sero" Izuku said before walking away.
Mina squealed from beside him, "Sero and Izuku sitting in a tree."
Sero shoved her, trying to get her to shut up.
"Want yourself a big strong alpha?" She laughed.
A loud scraping sound had Sero looking up. Bakugou had stood up, his chair scraping against the floor. The blonde threw his bag over his shoulder and Kirishima jumped up to join him.
"We better get going to class" Kirishima said, with the closest thing Sero had ever seen to a glare on the red heads face.
He jumped up to hurry after them, but they disappeared into the crowd and when Sero got to the next class they weren't there yet.
He sat down to wait, his stomach roiling at the thought of the upset omega, his upset omega.
Bakugou and Kirishima turned up right on the bell, and hurried off at the end of the lesson before he could even try to explain.
He forced a smile on his face as Izuku came over.
"We'll just go back and change, before heading off, yeah?"
"Yeah, sounds good."
When they made it back to their dorm it was already packed with other students from their class, but Sero could see no sign of blonde hair and red eyes.
Sero and Izuku arrived back just before curfew, Sero grasping a beautifully wrapped gift in his hand. Thankfully the common room was mostly empty so there was no one to question the package. He still felt unsure, but Izuku insisted that Bakugou would love it. He'd bought a second present just in case.
"Thank you for your help" Sero said sincerely and Izuku gave him a huge smile.
"I was happy to help, anything for Kacchan."
Sero tried not to feel a twinge of jealousy at both the nickname and the sentiment.
He hurried up to Bakugou's room, there was no time like the present. He knocked then waited, but no answer came. He tried Kirishima's room just in case the blonde was there, but again the door went unanswered. It was nearly curfew so he knew they couldn't be too far. There was nothing to do except wait until morning.
Unfortunately, Bakugou, aided by Kirishima proved quite adept at avoiding him, impressive since they usually spent most of their day together.
He turned up to class right on the bell and hurried out straight after, he had stopped eating lunch with them and didn't answer his door whenever Sero tried to visit him. Worse still the blonde had been unusually quiet, he hadn't threatened to blow anyone up in days. It made Sero distinctly worried.
"Bakugou!" He called as he jumped out of his seat and hurried off after the illusive blonde. "Bakugou, wait."
The blonde shouldered people out of his way but Sero was fed up with being ignored. His tape sprung out without fully realising what he was doing. It wrapped around the blonde and pulled him into the air.
"Let me the fuck go!" Bakugou screamed and Sero let out a deep sigh as he pulled the blonde toward him. Red eyes glared at him hard enough that Sero might have been scared if he didn't know the other so well.
"Can we please just talk?" Sero asked plaintively.
"Fine! Whatever! Just let me go!"
Sero pulled his tape back in, watching carefully to see if Bakugou would try to make a run for it.
"Not here" Bakugou snarled, stomping away from the gawking masses, Sero gladly followed.
They made it back to Bakugou's room, the blonde slamming and locking the door behind him. Sero took a moment to look around, he'd never actually been in the blonde's room before. It smelt incredible and Sero couldn't help but stare at the nest set up perfectly in the middle of the bed.
Before Sero could get a word out Bakugou started, "you don't have to say anything alright! I- I know you're with Izuku, I've- I've stopped trying to court you, just leave it ok. We don't need to talk about it."
Sero stared at the blonde who was fiddling anxiously with his pants and smelling of distress even around the scent patches he was currently wearing. His heart broke for him.
He took a step forward, but Bakugou backed away.
"I don't want to talk about it ok" Bakugou repeated. "It was stupid of me. Like I've said, I've stopped, its fine.
"It's not fine" Sero croaked, clearing his throat before starting again. "I'll admit it took me a while to realise what you were doing." Sero continued and Bakugou rolled his eyes.
"I couldn't understand how an omega as amazing as you would even be interested in me."
"Because you're only interested in alphas" Bakugou mumbled.
"Because I'm only interested in you. I couldn't understand, I still don't actually, how someone as amazing as you would even be bothered with me."
Bakugou frowned deeply at that.
"Oi, don't talk about yourself like that."
Sero grinned a little, naturally the blonde completely missed the part where he said he was interested.
Sero took a step forward and this time Bakugou didn't back away.
"Did you miss the part where I said I'm interested in you?"
The blonde blinked at him.
"What?"
Sero took another step forward.
"I said, I'm interested in you."
Blond eyebrows furrowed.
"I know you're not" Bakugou said quietly, looking down. "I've been trying for so long to court you; you've never shown any interest. I was getting ready to give up anyway when you went on your date" Bakugou's voiced cracked, "with Deku. You don't have to make shit up to spare my feelings."
"I'll admit it took me a while to realise what was going on and that I probably would've missed it if Kirishima hadn't pointed it out to me."
Bakugou made a noise of derision.
"But" Sero held up a finger. "Now I know, I've realised there is nothing I want more. As long as you still want me that is?"
Bakugou stayed silent, clearly unsure whether to believe him or not.
Sero opened his bag and pulled out a package.
"Izuku was just helping me find a courting gift for you, I wanted to do things right but wasn't sure where to start."
Bakugou's eyebrows furrowed in thought, taking a step towards the dark-haired teen and the present stretched out toward him.
"Izuku was just helping you choose something for me?" Bakugou asked unsurely, still not taking the gift.
Sero nodded, "please consider this my formal courtship request. Bakugou, you are everything I could ever want in a partner, and nothing would make me happier then if you were mine."
Bakugou blinked owlishly, finally reaching out to take the offered gift.
"I've got a second one, just in case you don't like this one" Sero said nervously.
Bakugou snorted as he ripped open the paper, staring wide eyed at the limited edition All Might action figure before him.
Bakugou looked up at him, then back down at the box, then back up at Sero, clearly processing.
"I love it" Bakugou said quietly, eyes dark. Placing the figure on his desk where it would be safe.
"You said you had a second present?" Bakugou asked, holding his hands out.
"Oh! Oh of course" Sero said, scrambling to pull open his bag and get the other gift. Thankful that he had gotten two now.
This one was smaller and Bakugou pulled open the paper he found an orange and black shirt inside with the word, Dynamite, embroided on it, with a tiny explosion for the dot above the i.
Bakugou ran his finger over the word, "you had this made for me?"
"Yeah" Sero said nervously. "I know you'll probably have your own merchandise everywhere soon, but I wanted you to know how much I believe in you.
Bakugou unrolled the shirt, "Will you wear it?"
"Me?" Sero asked in confusion.
"Yeah" Bakugou replied calmly, "so everyone will know just who you belong to."
While he was still processing Bakugou stepped in close and began pulling off his school blazer, shirt and tie before bodily pulling the orange and black shirt over his head.
"Mine" Bakugou groaned, pulling Sero in for a heated kiss. It took him a moment for his brain to catch up but when he did, he started kissing back enthusiastically. Pulling Bakugou into his arms and holding him close.
Bakugou rubbed himself all over Sero, hooking one leg around his hips and rutting up against him. He reached down, hands sliding into Bakugou's pants, grabbing his arse and pulling him even closer as he pushed his aching cock between the blonde's legs.
Bakugou reached down and quickly pulled the dark-haired teens pants down, he stepped out of them without preamble, before starting to strip Bakugou of his own clothing. He went to remove the Dynamite shirt, but Bakugou hissed at him and pulled it back down, so Sero decided the best course of action was to leave it on.
Then he took a moment to enjoy the sight of the gorgeous omega before him, small cock flushed red and slick dribbling down pale thighs. All Sero wanted to do was taste. So that's what he did. He dropped down to his knees, pulled one of Bakugou's legs over his shoulder before diving in, burying his face in the creamy pussy, groaning at the near dizzying taste. Bakugou let out a groan of his own, gripping Sero's hair as ground his pussy into Sero's face, practically spasming as Sero's nose rubbed against the blonde's clit and his tongue lapped greedily at his hole.
Slick ran down Sero's chin, but he didn't care. He brought a hand up, slipping a finger inside Bakugou next to his tongue and enjoying the way Bakugou near howled in pleasure.
"Ooh, oh, I-I'm gonna cum" Bakugou groaned, legs shaking as he leaned against the wall behind him. Sero doubled his efforts at the words, damn near suffocating himself in his eagerness to eat the other out.
Bakugou started panting above him, the grip on his hair becoming painful as Bakugou shuddered and came, slick gushing into his mouth and down his chin as the other rode out his orgasm.
Sero pulled back when he knew Bakugou was finished, gasping in some much-needed air and looking up at the beauty before him dazedly. Bakugou was still leaning against the wall, sweat gathered on his brow and chest heaving. Sero didn't think he had ever seen anything so beautiful.
He gradually stood up, Bakugou opening his eyes at the movement before leaning forward and lightly pushing his lips against Sero's, as though wanting to taste himself on the others lips.
Bakugou then dropped to the ground himself, taking Sero's prick in hand.
"It- It won't take me long" Sero gasped out, cheeks flushing slightly.
Bakugou didn't respond, merely opening his mouth as he worked Sero. Tugging just right with a slick coated hand, mouth open so he could lap at the tip with every downward stroke. It only took a dozen strokes before he was gasping, cumming all over Bakugou's face as the blonde kneeled there and took it, smiling contentedly as he was thoroughly marked. Sero felt his cock twitch valiantly as Bakugou reached up and started massaging the cum into his skin.
"Shit" Sero moaned at the sight.
Bakugou sighed, looking pleased as he pulled Sero into a deep kiss.
"Can't believe after everything I did, it took Kirishima pointing it out for you to realise I was trying to court you" Bakugou grumbled, though he didn't look upset.
"I may have been a little dense" Sero conceded.
"Yeah, no shit. I assume everything is clear now?"
Sero swallowed thickly. "It is."
Bakugou handed him a towel and they both cleaned off the worst of the cum, before pulling back on their clothes, Bakugou insisting that Sero leave the Dynamite shirt on under his school one.
"Come on, lets go down and get some dinner."
"Er… you don't want to shower first?" Sero asked, slightly confused.
"No" Bakugou denied, already pulling Sero towards the door.
As they walked into the common room and all heads swung to them, Kirishima letting out a loud whoop! Sero knew there would be no doubt about their relationship from now on.
