Chapter Text

Eijiro was eternally grateful for the changes that had come in the world. Being an Omega no longer meant that he could not be a hero. It certainly wasn’t common, he knew that. Being a male Omega was uncommon, too. His dam liked to say that he was simply rare, and that made him all the more special.

And he had flourished with his dam and sire. His dam had taken him to her nest every night to scent her. His sire had taken him out to work, to do everything she could to help expel his energy in a healthy way.

Neither of them were surprised when he declared he wanted to be a hero. That didn’t dampen their joy when he was accepted into UA. If anything, he suspected his dam was happy with this. It had one of the safest programs for Omegas in the nation.

So now here he was. A male Omega, not having had his first heat. It wasn’t uncommon for male Omegas to have theirs a bit later. He wasn’t able to be on birth control or suppressants until it happened. But he had scent patches, like everyone else in school. So he wouldn’t trigger a rut or anything.

The scent patches dampened scents, clamped down on those troublesome pheremones. But he was told his scent was still evident. The last remaining milky scent of pup, since he hadn’t had his first heat. But there was also something that he was told was like a fresh ocean air, something salty and comforting.

Everyone in class knew he was an Omega. And no one seemed to say much about it. Classifications didn’t seem to be a big deal to anyone. Although it was true that certain times, the Alphas seemed to flock together, wrestling and tumbling around the floor, mock growls and answering rumbles and chuffs. The matches always ended with someone showing their neck in submission.

Unless it was Bakugo and Midoriya, Eijiro thought. He loved watching the two of them, whether or not they were rolling on the floor in tumble, sparring in the gym, or simply walking by one another down the sidewalk to class. Alpha/Alpha pairings were fairly common, and sometimes there was a throuple.

Not that Eijiro thought that was even a possibility for Midoriya and Bakugo. They so obviously adored one another. It was obvious in the way that Bakugo would sling his arm around his boyfriend’s neck. It was clear in the way that Midoriya would help Bakugo tape up his wrists before sparring. It was in the way that Bakugo had to make sure that Midoriya had a full plate at every meal. It was in the way that Midoriya scented his boyfriend each night before he went to bed, sweeping his wrist down his neck and through his hair.

So no, Eijiro knew that there was no space for him there. They didn’t need him to come in and fill any gaps. It didn’t mean that the Omega in him didn’t howl and demand, didn’t ache, didn’t long for them.

“Kacchan?” Midoriya asked one late afternoon as he moved the pile of sweaters, jackets, and hoodies that seemed to get launched on one random chair when everyone came home from classes.

“Hm?”

“Did you take my All Might hoodie? The one with the hair pieces on the hood?” he frowned, continuing to move through the fabric in his hands.

“You ain’t gotta describe it, I didn’t fuckin’ take it.” Bakugo snorted. Midoriya sighed and moved on. And the hoodie did turn up a few days later! In the laundry. After Eijiro had slept with it on one of his pillows. He had also managed to take one of Bakugo’s many work out t shirts, put it in another pillow, and sleep between the two of them. It was the only way he could calm himself down enough to sleep. There was a restlessness inside of him, an itching in his skin that seemed to wrap around his bones.

But it was easy enough to quell that, he thought. Because just as one garment of clothing was starting to lose its scent, another would be strewn about, left where he could get easy access. It did prick at Eijiro a little bit, to know that he was taking something without asking. Not very heroic, if he was being honest.

But they weren’t overly upset, he told himself. And there were plenty of clothes. And it was helping him! It was common for an Omega to need a nest. Some preferred to sleep in them. Others only used them for heats, an illness in themselves or somewhere in their pack. Some still only really liked them in times of stress.

Eijiro wasn’t sure what had triggered his need. He was a fairly well adjusted Omega, he and his parents had been told that multiple times. He couldn’t even pin point what, precisely, was bothering him. All he knew was that having a nest was helping him feel more settled. Especially when that nest had the sweetened minty scent of Midoriya and the campfire smell of Bakugo.

So Eijiro would swap out the materials as needed. He was so glad they had a communal laundry room. It made it much easier to sneak things in and out without the other two noticing. Midoriya had commented a few times about the fact that the underpants gnomes that lived in the dorms seemed especially interested in his and Kacchan’s clothes.

Bakugo had scolded his boyfriend for being so careless with his things.

“Shitty Hair,” Bakugo barked one day as Eijiro stepped into the kitchen for some water. He looked at him with a grin, ignoring that warm sensation that crept through his body. It made him want to tip his chin back and expose his neck. It made him want to rub his wrists on Bakugo, scenting him. It made him want to nuzzle his neck and drink in deep breaths.

“Yeah, bro?”

“Here,” he thrust out a spoon with a mouthful of the dish he was cooking. Bakugo had cupped his hand underneath to catch any drips.
“Taste this and tell me what it needs.”

Eijiro scooted close and opened his mouth wide. Bakugo paused and blew gently at the spoon, steam wafting towards Eijiro. His mouth watered as he wrapped his lips around the spoon. Bakugo pulled it carefully from his lips.

“So?” he asked in a software voice, something more sultry. It was just this side of an Alpha command, something that made Eijiro’s legs quake. He chewed and swallowed, the flavors fanning across his tongue.

Now that he felt like he could make any kind of sentence that would be understandable. And if he could, saying something like “I want more, Alpha,” wasn’t going to go over well. Not when he was in a committed relationship.

“It’s good,” he mumbled. Bakugo scoffed, muttering how unhelpful Kirishima was, and to get out of the kitchen if he couldn’t be helpful. Eijiro scurried out, clutching his water bottle, feeling dazed.

“Is everything okay, Kirishima?” Midoriya asked with a frown. Eijiro stared at him, mouth working like a fish. He swallowed a few times.

“I’m fine, Midobro.” he managed. Midoriya frowned and looked at him a little closer.

“That’s good, I’d really hate to see something happen to my classmates, you know?” he had risen from the couch and was walking towards him. Eijiro nodded a few times, his knees trembling, though he wasn’t sure why.

“I know, you’re so kind to all of us.” he said without thinking. Midoriya smiled. But this was not his typical bright smile. This wasn’t the ‘try your best and believe in yourself’ look that Eijiro admired so much. This was, instead, something well pleased, something a little bit hungrier. Midoriya was on the edge of chuffing at him.

Without thinking, Eijiro was showing his neck. A scarred hand came up and pressed gently to his neck. His thumb rubbed against his scent gland. Eijiro’s eyes fell half mast, and an ocean smell was stronger between the two of them.

“Why thank you,” he hummed. “I’m so glad that you’ve noticed.”

The spell broke when Eijiro sucked in a breath. He backed away quickly, glancing at the kitchen. Midoriya followed his gaze, but didn’t seem particularly concerned. Eijiro just smiled, feeling a little frantic, backing away before running up the stairs.

That was too close.

Eijiro loved sparring. This was, in part, due to his touch starved nature. He knew that he could go to people and ask for the things an Omega needed. A hug, a cuddle, someone, anyone touching him. It was particularly important for an Omega to have touch, it made them feel whole and settled.

Sparring helped, he thought. It gave him a chance to touch and be touched, even though he knew that it wasn’t the same. And no one was allowed to growl, or squeeze that gland in the back of his neck. No one was allowed to pull his face into their neck, get him scent drunk. Like that would have been possible with the stupid patches, he thought glumly.

He would never say out loud how much he loved sparring with Katsuki. It was true that they were fairly evenly matched. His quirk meant that he was a little bit physically stronger, sure. But that didn’t mean he could outwit the Alpha. He loved sparring with Midoriya, too, of course. His quirk made him a real challenge, and he moved so much quicker than Eijiro.

He loved being kept on his toes. He loved having to think fast. He loved when one of them would pin him down, wrists held above his head. One of the Alphas would be straddling him, looking down at him. Teeth would be bared in the way that Alphas did, a sign that was a threat to a challenger. A sign that was alluring to Omegas.

“You’re going down, rocks for brains.” Bakugo warned. Eijiro just grinned, ignoring the way his skin broke out in goosebumps. If he acknowledged them, he’d have to consider what it was all about. He could have lied to himself and said it was the thrill of the spar, but how much longer could he tolerate lying to himself?

Bakugo lunged for him, and he was able to slip away at the last second. Bakugo growled, low in his throat, jaw clenched. It made Eijiro’s thighs weak. He was grateful that he wore padded underwear under his workout pants. Otherwise he knew that his pants would be stained with slick. He was always dripping wet after a sparring match. No one ever noticed, or said anything if they did.

Still, the padded briefs gave him a lot of security.

Bakugo was after him again, trying to fling some blasts. Eijiro managed to activate his quirk in time, protecting his skin. Bakugo roared, launching himself into the air. He did have an advantage, given the lift his blasts gave him. Eijiro admired and envied that quite a bit.

They carried on for most of class, sweat dripping down their foreheads. They had devolved into hand to hand combat, wrestling each other on the mat of the gym. Eijiro had his legs wrapped around Bakugo’s waist, squeezing as he tried to flip him. But the Alpha trained hard, and Eijiro was tired.

It wasn’t too long before Katsuki had him pinned down. His wrists were by his head again, Katsuki’s nose just inches from his. He took in the heavy campfire smell, enhanced by the way the Alpha was sweating. He was showing his teeth again. A whine bubbled up in Eijiro’s throat. He wanted to wriggle beneath Katsuki. He felt slick pooling in his pants and swallowed hard.

“Got’cha,” Katsuki said in a low voice. His thumbs were stroking the tender undersides of his wrists. Right on his scent glands. It felt like electricity going through his body, and Eijiro wasn’t sure if he wanted to show his neck, or try and hump Katsuki, or beg to kiss him, or all of those things.

Katsuki was breathing hard, his chest heaving. God, those pecs, Eijiro thought, a little deliriously. He could barely concentrate on one thought with the way there was heat bubbling inside of him and underneath his skin.

“And that’s class!” All Might call cheerfully. “Let’s pack it in everyone.”

Without another word, Bakugo slid off him, rising up from between Eijiro’s legs. Eijiro stayed on the mat for a few moments, trying to collect himself, trying to calm himself down. He was grateful that no one could tell he was slicking his bottoms, grateful no one could hear his thoughts and the way his inner Omega was howling and begging him to rush after Katsuki.

Alpha, Alpha, Alpha! Need Alpha!

Of course he needed the Alpha, he thought bitterly. Midoriya was standing right there, waiting for his boyfriend. He had a towel he used to wipe Katsuki’s face, draped it over his shoulders to collect from the back of his neck.

A smile was shared between the two of them. A light that entered Katsuki’s eyes whenever he looked at Izuku. It was beautiful to see, it was crushing to feel. Eijiro stayed on the floor while the two of them walked out. Once he was sure that the locker room would be mostly deserted, he crept towards it.

When Eijiro enrolled, Nezu had made it clear that there could be an Omega change room. He swore to Eijiro and his dam and sire the boy would be protected at all times. There wouldn’t be any harassment or bullying in his school. His sire had been pleased, but his dam had said the choice had to be Eijiro’s.

“My son can choose for himself.” she said in the calm, firm way she had. Not even his sire would dare to argue with her. Instead, she put her hand on her wife’s shoulder and smiled.

“My better half is correct.” his sire said. “We’ve raised our son well enough, we trust him, and I would never let him go to a school that I couldn’t trust. If Eiji says he’s fine in the regular locker room with the Alphas and Betas, then that is where he will change.” she set her chin in the same stubborn way Eijiro did.

Nezu acquiesed.
Sure enough, the locker room was abandoned. Eijiro stood under the steamy showers for a time, letting the water pound down on him. He normally tried to keep his hair dry, but today he couldn’t find it in himself to care.

His hole was still oozing slick, too. He leaned his hands and forehead against the tiles, feeling it washing away down his thighs. It would have been nicer, he thought, for someone else to clean him up, whisper teasing remarks on how turned on they got him.

No, he corrected himself. Not someone. Katsuk or Izuku. He wrenched off the water and padded towards the lockers in his flip flops. He hadn’t quite tied his towel around his waist when he heard a gasp.

“M-M-Midoriya!?!” he stammered when he looked up and the saw the other boy standing there. He was blushing furiously, his green eyes looking carefully around, clearly trying to avoid staring.

“I’m sorry I’msorrysososrry, Kacchanforgothiswaterbottle!” he blurted it all out, looking like he was going to faint. Eijiro had secured the towel by then. He couldn’t pretend he wasn’t blushing, but he was going to try his damndest to pretend he wasn’t getting a little slick at the idea of Midoriya being so close to him naked.

“You didn’t mean to.” he stared down at his flipflops. Midoriya didn’t run. He stood there, watching the water as it dripped from Eijiro’s hair. He stepped closer, slowly, the way one would when they were trying to approach a stray cat they wanted to pet.

“I didn’t,” Midoriya agreed. Mint filled the air, awakening something in Eijiro. He locked eyes with the Alpha, wondering what he was expecting to see, or hoping for. Midoriya reached out, a scarred hand landing on his chest. Eijiro let out a questioning chirp, answered by a low rumble. He sank onto a bench.
“You worked so hard today, I noticed. Even Kacchan commented.”

“He did?” Eijiro perked up. Midoriya smiled, and Eijiro felt his chest swell. There was nothing an Omega liked more than praise.

“Wouldn’t stop talking about it. If you get dressed, I’ll walk you home for dinner.”

“Okay, yes, sure.” Eijiro jumped up and hurried to his locker. He missed the gleam in Izuku’s eye, and the dangerous upturn of the corners of his lips.

When it was finally the weekend, with time off, Eijiro found himself awoken by someone repeatedly poking his shoulder. He groaned and rolled over, looking at Bakugo staring down at him. Eijiro immediately felt panic rising in him. He tried to stuff the pillow that had Bakugo’s t shirt on it under something else, and grab Midoriya’s hoodie and cram it under his blanket.

“What are you doing in here?” he hissed, a little harsher than he meant. Bakugo’s eyebrows raised. The Omega almost never spoke to him like that. He scoffed and turned away, looking instead at EIjiro’s messy desk.

“Came to get you for a run, rocks for brains. Not my fault you forgot you told me you wanted to.” oh, right, he had asked for that. He felt a little sheepish as he sat up, rubbing at one of his eyes.

“Sorry,” he mumbled. Katsuki clicked his tongue and turned back to him.

“You’re such a mess.” he scolded gently. “I thought Omegas liked to keep things tidy.”

“A common myth.” Eijiro smiled faintly.

“Even your hair is a mess. I am not going out with you looking like that.” Eijiro wasn’t sure why it mattered, since they were going to be on a run anyway.

“Give me a minute and—.”

“Just–sit still.” Bakugo had his comb from his desk. He froze in his nest as Bakugo leaned over him. The Alpha’s hands finger combed through his hair, freshening up the stiff peaks. He closed his eyes and tilted his chin back, just a little bit, as Katsuki used the comb to help with a few tangles.

How could he be so gentle? Eijiro had never known him to be so careful, especially with his hands. He felt the beginnings of a purr in his chest. Katsuki continued to work his fingers through his hair, the Omega’s eyes were half closed.

One of Katsuki’s hands slid down the back of his head. He stopped at Eijiro’s neck, feeling ever so carefully for the gland back there. The tips of his fingers brushed against it, relaxation spreading through Eijiro.

If the Alpha had let his hand leave his hair, gone and rubbed at the gland at the small of his back, Eijiro was certain he would have instantly submitted. No one had touched him like this since he was a very small pup when his parents were putting him to bed.

He didn’t know how much he would like this.

“Is that it?” Katsuki’s voice was low and husky. “You needed a little attention?” Eijiro wondered, faintly, if Katsuki could smell how much he was enjoying this. Likely so, since he hadn’t put on his scent patches. He was able to catch snatches of Katsuki’s satisfaction, and he inhaled even deeper, trying to suck in more of that scent.

Made Alpha pleased, a voice whispered in his head. Happy Alpha, happy Omega!

He gave the softest purr. Katsuki gave a short, dark laugh. Eijiro couldn’t even turn his head to look at him as the pressure at the back of his neck increased, making his shoulders drop.

“You’re such a good Omega.” the Alpha sighed happily. Eijiro let out the tiniest little trill, immediately answered with an Alpha rumble. But then the door opened and he startled, hurling his body away from Katsuki.

“Are we ready for our run?” Midoriya asked brightly, apparently not understanding what it was that he had interrupted.

“Don’t you ever knock, you nerd?” Katsuki snarled. Midoriya just laughed and pointed to Eijiro’s jacket at the back of his desk chair.

“Don’t forget to put that on! Little nippy out today. Come on, Kacchan, I have your protein shake all ready for you.”

The two of them left, and Eijiro wondered if it was possible for the air to be sucked out of a room. He slowly climbed out of his nest and went to his dresser, pulling on clothes and then brushing his teeth as quick as he could.

Their run was nice, although no one was speaking. Eijiro lagged behind the other two. He wondered if he should say something to Midoriya. But then, had he spoken to Katsuki when Izuku had touched his neck? Had he said anything to either of them about what was going on?

Should he? What if he was reading too much into it? What if he just wanted them both so badly, and wanted them to want him, that he thought there was more here than there was? His thoughts churned in his mind.

“Come on, slow poke!” Midoriya called out. “You’re gonna miss breakfast.”

“And I ain’t saving you any French toast!” Bakugo warned.

That was enough to make Eijiro pick up the pace.

“Here,” Bakugo grunted as he put another plate of hot French toast in front of Eijiro. The Omega beamed at him and fell to eating with gusto. It wasn’t unheard of for him to pack away the food. Almost all the students here could chow down, since so many of their quirks required a lot of calories.

What he didn’t seem to notice, as he poured more syrup on his breakfast, was that Bakugo wasn’t making anyone else plates. He had made breakfast and left it on a platter. Everyone else had to go and make their own plate. He was the only one who was getting hot and fresh food.

He also did not notice the glances that were being exchanged by the Alpha pair.

Kaminari did open his mouth at one point, likely to protest. He was always quick to notice disparities like that. But Iida had clamped his hand over his mouth and shook his head. No one said anything as Eijiro devoured his food, along with the orange juice and water and Izuku kept giving him.

Eijiro felt full and satisfied, content and calm. He could have purred for no reason at all! Bakugo looked smug as he grabbed his arm and steered him to the common room. Midoriya had darted ahead, and was setting up the couch with blankets and pillows.

“We’re having a movie marathon.” he announced. “Of some of the classic heroes! And I got the Crimson Riot movie you love so much.” he tempted. Eijiro’s jaw dropped. He had been nagging for someone to watch that with him. And here was the Alpha duo that haunted his every dream volunteering!

“Yespleasethankyou!” he said quickly without a breath. Midoriya chuckled, giving him that bright smile that made him feel weak in the knees.

“Sit there, Shitty Hair.” Bakugo pointed to the middle of the soda. He parked it on one side and Izuku was on the other. Eijiro frowned, confused.

“You two normally sit together.” he swallowed hard. Was there a rift here? Were they going to break up? And if that was the case, was he the cause of it? Distress leaked from under his scent patches, making Bakugo scowl and Midoriya bolt towards him.

“No no no, I just want to lean on the arm rest, see?” he gestured. “And so does Kacchan! There’s nothing wrong, everything is fine. Besides, I put the best pillow there for you.”

“I just–.”

“Sit down,” Katsuki said in a sharp tone, edging towards an Alpha command. Eijiro sat, looking with wide eyes at the television.

“Don’t be like that, Kacchan.” Izuku scolded. He reached for the Omega’s hand, pulling it into his lap. He rubbed gently at the underside of his wrist, wafting out soft scents of assurance and calm to him.
“He just wanted to make everyone comfortable, like he always does. Eiji always wants everyone to be happy. He does everything he can to make that happen. THat’s why he’s such a good Omega.” Eijiro’s scent was back to his ocean one.

“Sorry,” Katsuki pressed his shoulder into Eijiro’s. “Let’s just watch the movie.”

An apology and both of them were touching him?!? His heart was going to burst right out of his chest! He tried to focus on the screen as Izuku started the movie, his other hand not letting go of Eijiro.

What was happening here?

Chapter Text

Eijrio didn’t seem to notice too much when seats changed in class. He was now parked right in between Midoriya and Bakugo. He squirmed a bit in his seat. Wouldn’t they want to be next to each other? He wasn’t sure if it was worse being used as a buffer or what.

Eijiro did his best to try and ignore it. It was more important that he focus on class. The irritation that seemed to be bubbling underneath his skin. He tried to ignore the sensation. It was gnawing at the edges of his nerves. He was so close to snapping. He was hungry, but nothing sounded good, he was tired but spent most of the time tossing and turning in his nest.

If he was being honest, the only thing that made it better was when the alphas were around. It didn’t resolve everything, but it helped. He’d spent most of the morning ripping apart his nest and trying to weave it back together. Nothing helped.

The lesson wasn’t interesting, no matter how much he tried to focus. Eijiro folded his arms on his desk and put his head down. He thought that Bakugo would elbow him, as he typically did if he was trying to slack off.

“Whoa,” Sero said suddenly, sharply. The rest of the class was beginning to stir. Eijiro didn’t lift up his head. The air was full of a sweet smell, edged with something like desperation. He was gripped by the strange cramp in the pit of his stomach and moaned.

“Kirishima,” he turned his head and opened his eyes. “You didn’t know, did you?” Aizawa was there, reaching to place his hand on his head. It shocked everyone that there was a growling sound coming from Midoriya.

“Deku,” Katsuki scolded.

“Don’t touch!” Midoriya was out of his chair, his lips pulled back in a perfect, threatening snarl. The air was thick with Alpha posturing and the smell of a virgin Omega in heat. Kirishima’s eyes darted between Midoriya ready to lunge at Aizawa, Bakugo looking put out, and the rest of the class staring.

“Everyone out!” Aizawa snapped. The rest of the class hurried out of the room, not daring to look back over their shoulders. “Take care of him.” he directed the two Alphas left in the room. Bakugo had hurried to the door, locking it and pressing his back to it.

“Eijiro, Eijiro,” Midoriya’s voice had gone soft and gentle as he approached the desk. Eijiro whimpered again, letting out a small whine. It sounded so small and lost, Midoriya felt his heart ache.
“You don’t feel good, do you?”

“I didn’t know.” he admitted, feeling the cramp in his belly. He gasped and tried to curl in on himself. Midoriya was gathering the Omega to him, rubbing the back of his neck. It was the gland that would settle any Omega, and it did seem to help Eijiro a little bit.

“You weren’t expecting your heat. Poor baby.” he cooed. It was a Coddling gesture, and normally Katsuki would have snapped at his mate. But clearly the Omega needed it. He felt better having the door blocked.

“We gotta get him to the dorm.” he said grimly.

“Your nest! Do you want your nest, Eiji?” he asked, rubbing his wrists behind the Omega’s ears. He was coating him in his scent, even if the Omega didn’t clock it. Katsuki was satisfied watching. He knew the scenting would keep him a little calm.

“Nest,” Eijiro agreed. He reached out and wrapped his arms around Midoriya’s waist. He nuzzled in between his pecs, still in his seat. No one spoke for a bit and Midoriya played with his hair.

“Let’s go to your nest.” Bakugo opened the door and peered around, mollified when it was empty. He gestured back into the classroom .The other two would follow him, no problem. The same way they always did.

“No! No! No!” Eijiro let out a frantic cry when Midoriya pulled away. He whined, his fingers flexing in grabby hands the moment Midoriya wasn’t pressed against him. He let out distressed trills, only calming when he was answered with twin chufts from the Alphas.

“We have to get you to the dorm, shitty hair.” Bakugo explained softly. “That’s where nest is, and that’s where we’re going to keep you comfortable and safe. Get up, and let’s go.” it was not an Alpha command, although Bakugo would be lying if he didn’t admit that it had crossed his mind.

Eijiro shook his head several times. Midoriya glanced at his mate and then smiled, looking down at the Omega in his arms. He nuzzled the top of his head, hoping that he had enough control of his scent glands to send out calming and acceptance and Safe Safe, Omega is Safe.

“If you come with us.” he tempted. “Then I can get you a brand new blanket for your nest. One that was on the bed when Kacchan and I slept.” Eijiro’s eyes took on a greedy gleam. Got ‘em, Izuku thought.

“For my nest?” he asked, suspicious.

“Of course, darling.” he assured. Eijiro stood up, rubbing at his eyes. He whined, pressing his hands to his stomach. Izuku made a sympathetic sound.
“Oh, we know, we know. Let us get you to the dorm and you’ll feel better.”

“It hurts so bad.” he whined.

“And we’re gonna help, but you have to listen and stop arguing.” Katsuki reached out to brush his fingers against the Omega’s cheek. He smelled so good, Katsuki thought desperately. It was so hard for him not to throw him on a desk, rip his pants down, and bury his face between those asscheeks he had been watching in the gym without getting caught.

Eijiro was finally letting Izuku walk him out of the room. Katsuki made sure that he was standing in front of them, refusing to let them walk a single step until he had surveyed the area. And as much as Izuku was in a rush to get the Omega to his nest, his mate was right. Had to keep him safe first.

Eijiro was aware of the way that he was beginning to leak slick. His face was hot, and he wondered if he could blame it on the heat. He silently, frantically thanked whatever God might be listening for the padded underwear he was wearing. He clung to Midoriya, grateful there were slow steps for the hell pain in his belly.

“It hurts!” he declared when they were halfway to the dorm. Izuku might have been shocked, but he figured the school had to have some kind of protocol. After all, they couldn’t let Omegas who were right at the age for presenting and having uncontrolled heats just out without any kind of protection. Likely teachers were watching where they couldn’t see, and the cameras had to be watching them.

“I know,” Katsuki soothed in a soft voice that only Izuku had known of before. He glanced at Izuku, who quickly swapped places, keeping guard as they continued their slow trek to the dorm. “We’ll make it better in your nest.”

Eijiro was quiet as they made it to the dorm. He was hustled onto the elevator, boxed into the corner by both Alphas. They kept murmuring encouragement to him, rubbing any inch of bare flesh they could get their hands on.

“Finally,” Katsuki grunted as he half dragged the Omega into his room. “Deku are you-.”

“Right away, Kacchan,” he ushered them in, making to leave. But a desperate whine and the overwhelming scent of fear made him freeze.

“No, I’m sorry, don’t go.”

“Oi, he’ll be right back.” Katsuki frowned. “He’s going to get some stuff we need. Because we want to take care of you.”

“You want to?” Eijiro repeated.

“More than anything.” Izuku had cupped his face, roughened thumbs rubbing just under his eyes. Eijiro exhaled, his body loosening.
“So Omega is gonna go stay with Kacchan, and show him your nest.”

Eijiro took a few steps back, slowly, like it hurt. Maybe it did, Izuku thought. He closed the door and hurried to his own room, where the promised blanket was, along with a bag of some other items.

The Omega turned to the mess of blankets he had and immediately began crafting a nest. Katsuki stood by the door, arms crossed as he watched. The Omega didn’t even look at him, focused on his task.

When the door opened again, Katsuki had dropped into a threatening stance. Eijiro was shrinking away. Both of them released when they saw it was simply Izuku. He smiled brightly and held out a blanket to Eijiro.

“It’s perfect!” the Omega enthused, snatching it burying his face into it. He took deep inhales, taking in the scent of both Alphas mixed. He crawled into his nest then, winding it around his body. He barely noticed the muzzles that Izuku and Katsuki had put on.

“Is that better, baby?” Izuku cooed, Eijiro saw the muzzles and frowned, reaching for it. Izuku caught his wrist gently and pressed Eijiro’s hand to his chest.
“No, we need them.”

“You wouldn’t hurt me.” his speech was beginning to slur, sweat beading at his forehead and at the back of his neck. “You could never.”

“Damn straight,” Katsuki agreed. “But we ain’t gonna bite you today either.” for some reason, this felt heart breaking. He whimpered his lower lip quivering.

“You don’t want to bute me?”

“That ain’t what I said.”

“What Kacchan means,” Izuku rushed in. “Is that we can’t bite you without a long conversation that you’re not in a space to have. We just want to help you through heat for now. And then we can figure everything else out. So all my Omega needs to do right now is lay down and get comfortable.”

It was a simple request, a smooth set of directions that Eijiro could obey. He curled under the blanket, opening his mouth without question for the pain medicine that would help with his cramping, sipping from the bottle of water Katsuki cracked open and held for him.

“There,” Izuku sounded satisfied. “Look at you in your perfect little nest. It’s so lovely, Eijiro. I can’t wait until you make a nest we can all fit in.” the Omega blushed. There were hands in his hand, working down to the back of his neck. Another set of hands was at the small of his back, rubbing at the gland there. Combined with the hand on his neck, Eijiro knew he was being gentled.

“Settling your ass down, isn’t it?” Katsuki chuckled. Eijiro didn’t respond, the smallest purr coming from him. The ache in his belly wasn’t as bad, and he felt better. Calmer. Comfortable. But the hands on him didn’t leave, and how could an Omega stay awake with all of that?

When Eijiro woke up again, he was flinging the blankets off his body. He whined, heat wrapped around him in a chokehold. There was sympathetic humming, and then a cool cloth wiping at his face. When he forced his eyes open, he saw Izuku there, tenderly cleaning his face.

“Alpha,” he whined.

“I know it, baby.” he said past the muzzle. “Fuck, you smell so good right now.” gone was the milky pup scent, replaced with the ocean smell, and the underlying smell of heat and want and need. Izuku’s fingers twitched as he moved the cloth.
“You need a drink?”

“No, I need you.” he reached out desperate hands. Izuku looked pained as he took Eijiro’s hands, kissed the fingers and pressed them to his own chest.

“Calm down.” he murmured. There was a stirring, and Eijiro turned his head sharply to see Katsuki there. He reached for him with one hand, satisfied when Katsuki took it and kissed the palm.

“I’m right here.” Katsuki assured. “Goddamn, you smell delicious.”

“Touch me,” he begged, delirious with heat and want. Katsuki and Izuku exchanged a glance. Wordlessly, Izuku reached for Eijiro’s pants. He lifted his hips eagerly, finally falling still and quiet.

“Brat,” Katsuki teased. “Think you’re getting what you want, so now you behave?” Eijiro just gave him big wet eyes, and he melted visibly. Izuku was easing down his padded underwear, wet with slick that was still coming.

“Eijiro,” Izuku began. “You know the very moment you tell us to stop, we will. You understand?” he nodded.
“No, baby, you need to use your words. We need verbal answers.”

“Your body has already answered for you.” Katsuki added. He grunted as one of Izuku’s sharp elbows met him in the stomach.

“I know you’ll stop. Alphas take good care of me, Alphas wouldn’t hurt me.” Eijiro was almost incoherent. Izuku rumbled to him, satisfied with the answer. He reached slowly, carefully, between the Omega’s thighs and to his hole. It was sopping wet, as he had expected. Still the red head gasped.

Katsuki had helped him off with his shirt. Once his chest was on display, he was smirking behind his muzzle. His tongue, that wicked wicked tongue that Eijiro had been watching for so long, darted out to lick his lips.

“Goddamn, you’re a beautiful Omega.” his cheeks must have been as red as his hair, he thought as he felt Katsuki’s eyes burning into his flesh. He gasped then, feeling the very tip of Izuku’s finger playing with the rim of his hole.

“Stop, don’t tense up.” Izuku said. “Stay nice and relaxed like you are now. Such a good boy, aren’t you? Listening so well.” he praised. That made another rush of slick come gushing out.
“Got a praise kink, Eiji?” he laughed, a soft sound full of promises yet to be understood.

“‘Course he does, he’s basically a golden retriever.” Katsuki snorted. But his hands were busy, too, finding Eijiro’s nipples and teasing them into stiff peaks. His mouth watered. And he ached to take one and suckle on it, see if he could make Eijiro whimper, whine, moan, or beg that way.

Stupid muzzle, he thought. He understood, logically, the point. He even agreed that they should wear them! But right now, with the ocean smell and the miles of bare skin he had been dreaming of, he wanted to rip it off. The feral glint in Izuku’s eye told him that his mate was feeling the same.

“Oh!” Eijiro cried out as the tip of Izuku’s finger pressed inside of him. His eyes fluttered closed, and his thighs spread wider. His fingers flexed, and Katsuki handed him the blanket that they had both scented.

They had been scenting it for days. They wrapped themselves up in it when cuddling. They rubbed it on the glands in their neck every night. They made sure it was saturated in the smell of them. The next step would have been to beat off into it, but Izuku had said they weren’t at that stage yet.

“He doesn’t even understand that we’re courting him, Kacchan.” Izuku laughed. “A gift like that would just turn him upside down.”

Katsuki had been impatient, grumbling and growling and asking why the hell that extra couldn’t see how much they liked him. What did he not understand? What were they doing wrong!?

“Nothing, Kacchan.” Izuku laughed again. “He’s a male Omega in a place where there aren’t many, and he likely just doesn't know. You know they’re late bloomers.” he had blushed a bit admitting this.
“We do all of this on Kirishima’s timing, not our own.”

“But he’s taking forever!” he complained. Izuku had pulled him down onto the bed and wrapped the blanket around him. He had known him for so long, it was easy for him to pull Katsuki close, press kisses to his sulking expression until he finally gave a small smile.

“All good things come in time.”

“I hate when you’re so level headed.” Katsuki mumbled. But he allowed himself to be distracted.

Now, though, he had the Omega ready and willing, fertile and open, desperate and wanting. Katsuki wasn’t sure if he was ever going to let himself dream of Eijiro wanting them. He tweaked a nipple and listened to him moan.

“You like that? You like praise and a little bit of pain? Aren’t you just perfect?” Eijiro’s eyes rolled back into his head as Izuku’s finger was finally fully seated, stretching him in the most delightful way.

“Such a sensitive Omega.” Izuku clicked his tongue. He moved his finger in and out in the shallowest thrusts, listening to the moaning of the Omega.
“You gonna cum for us? We get you to cum and we break this wave of heat, and you’ll feel so much better. And we’ll get another rag to wipe you down.”

“Sn-snuggle,” Eijiro managed.

“Snuggle?” Izuku repeated. “Oh, Omega, you want us to hold you?” he nodded, not meeting their gazes.
“Of course. We’ll do all of that as soon as you let go for me.”

His finger was moving faster, and his other hand came around to Eijiro’s cock. It was small and adorable, he thought, the perfect size and shape for an Omega. He groaned when Izuku began to rub it, feeling it chub in his fingers.

Eijiro’s hips were bouncing, trying hard to get more friction, to get more of Izuku’s finger inside of him. He couldn’t think straight, only knowing that he wanted more. Izuku laughed and crooked his finger a little, rubbed his cock a little harder before he screamed, cumming hard, landind hard in the nest.

Izuku kept murmuring gentle encouragement as he did so. Katsuki took his hands off his nipples and reached for another warm wet cloth. Eijiro felt his face heat up as Izuku wiped his thighs and hole and cock clean.

Neither of them spoke as they laid out in the nest, one on either side of Eijiro. It was a tight squeeze, but no one was complaining. There were hands in his hair, at the back of his neck, hands stroking down his sides. He reached out, wrapping his own arms around the waist closest to him, desperate to be held.

“Clingy,” Katsuki grunted.

“Perfect,” Izuku countered. “Rest now, baby,” he soothed. Eijiro looked at the muzzle and frowned. He reached to try and undo it, his hands shaking, fingers clumsy.
“No, it has to stay on. Just rest.” he shook his head, gently pulling his hands away. “Rest, Omega.”

Chapter Text

It was a long several days. Eijiro wasn’t sure the exact passage of time. He’d wake, desperate and aching. His hands would reach for one of them, the scent of Alpha thick in the air around him. He’d pull them close to him, spread his legs, too out of it to be embarrassed at the way his hole was leaking slick.

All he cared about was getting that hole filled.

Izuku would kneel between his spread thighs, wrap them around his waist. He’d let his hard cock rut against Eijiro until he was mewling, begging. Izuku seemed to take pleasure in how whiny and desperate he could make the Omega.

Neither Izuku nor Katsuki would penetrate him. It was a fact that frustrated Eijiro to no end. But every time he tried to bring it up, the Alphas would do something to distract him. They would roll him onto his belly and rub the small of his back, soothing and calming him, or rub his shoulders, alleviating the tension there.

They would coax bites of food to his mouth, distracting him with soft words of praise and adoration. And sometimes, most of the time, they would shut him up by putting something in his mouth. It was common for him to have Izuku between his thighs while Katsuki was kneeling by his head, his cock pressed to his tongue, sucking hard.

“You like that? Such a good Omega. Do I taste good?” Katsuki purred, his hands tangled in Eijiro’s hair. Eijiro would nod as best he could, hollow out his cheeks, and suck for all he was worth.

Which was not to say that Katsuki wasn’t between his thighs, too, humping against his ass, slick dampening his cock as he thrust. There was even one memorable wave of heat where Izuku was humping him, eyes rolled back in his head, while Katsuki was behind him, tongue apparently wedged up his asshole. And Eijiro knew he had a wicked tongue, had felt it in his own hole, licking around the rim, sliding inside him to sample and enjoy him.

Eijiro’s thighs were continually wet from slick or cum or both. After every wave was over, one of them would wipe him clean. Izuku used such tender motions, kissing his skin as he did. Katsuki was a little more clinical about it, but always dragged him into his arms afterwards, his wrists rubbing against Eijiro.

“There’s no way I don’t smell like the two of you.” Eijiro had laughed towards the end of his heat. “I’m practically marinated in your scent.”

“Good!” Katsuki smirked. “That way every extra that walks by will know that you belong to us. Our Omega.” he declared.

“Should we talk about–?”

“No,” Izuku cut him off gently. “We shouldn’t. Here, baby,” a straw was placed between his lips, and he sipped the sports drink. Izuku looked satisfied and laid down on one side of him, sandwiching him in the middle.

The Alphas were the happiest when he was laying there, drowsy and sweet, purring. They would rumble back to him, a sense of calm, of ‘rightness’ would drift over them. Eijiro wished the moments could last forever, but he understood that a conversation had to happen.

When the heat seemed to have broken, he sat up in his nest, rubbing his eyes. Izuku stirred, waking, eyes looking sharply at the Omega. He relaxed after a deep inhale, telling him heat was over. He sat up himself, arms stretching over his head. He reached back and undid the muzzle, letting it drop.

“Are you ready for a shower, baby?”

“Are you still calling me that?” Ejiro blurted. Izuku looked confused.

“Yes? Why wouldn’t I?”

“Be-because you were only helping me through heat?” Izuku cocked his head, obviously still not understanding. “Because you’re already mated to Bakugo, and he’s like my best friend. So of course you’d want to be kind to me.”

“You really do have rocks for brains.” Katsuki snorted through a yawn. He undid his own muzzle and rubbed at the hinge of his jaw.
“No, idiot.”

“Kacchan!” Izuku scolded. “We agreed to be kind.”

“I am! I didn’t swear.” he huffed.

“Anyway,” Izuku sighed. “No, darling, this wasn’t just about heat.” he reached out to brush some of Eijiro’s messy hair from his face.
“You really didn’t notice?”

“Notice…?”

“I admit that we were a little covert in our courtship.” Izuku shrugged. “I was scared of frightening you away.” Eijiro’s jaw dropped.

“Yeah, but can I have some of my shirts back now?” Katsuki grumbled. “You have some of my favorites, and I like them.”

“I’m sorry!” the Omega squeaked.

“It’s okay!” Izuku hurried to say. “We left them for you. We wanted you to have them. We’ll trade them out for new ones so you can still have something of ours in the nest, okay?” Eijiro blushed and nodded, clearing his throat.

“I don’t understand, though. The two of you are so happy! You don’t need an Omega.”

“Yes we do,” they said in unison. “We need you.”

“Me?” he repeated, weakly. Tears stung his eyes. Katsuki let out a long sigh.

“Are all Omegas emotional after heat, or just you, shitty hair?” he climbed out of the nest and set about gathering clothes.

“Come here, we need to get you to the shower.”

“But you’re mad.” he said in a small voice.

“No, I’m not.” he was refraining from rolling his eyes, Eijiro could tell. “I just want to get you clean and dressed and sat down to a proper meal.”

“Come on, baby.” Izuku stood too, pulling on clothes. “Kacchan will rinse off and then go and cook. I will get you all cleaned up.”

“You will?” he tried not to look too eager.

“Yes,” he laughed. “Come on, Omega, up.” Eijiro rose, letting Izuku dress him in sweats and a t shirt as all three of them headed for the shower.
“And Katsuki is going to make our Omega something delicious.” Izuku hummed as he poured body wash into Eijiro’s loofah. Eijiro noted with a secret thrill that it was Izuku’s body wash. He slowly, carefully began to scrub EIjiro’s back.

“Damn straight.” Katsuki smirked. “Gimme a kiss so I can go and get something made. I want to have extra time, you know all the idiots will hover around while I cook. I want something hot and filling as soon as you two get out to be ready.”

Katsuki wrenched off his shower and went to where the other two were. He gave Izuku a distracted kiss while putting a towel around his waist. Eijiro felt his face grow warm and gasped when Katsuki grabbed his chin and gave him a kiss.

It was hot, Eijiro thought. Hot and smoldering and full of promise. He trilled into the kiss, answered with a muffled rumble. Katsuki pulled away and let their foreheads rest against one another.

“Don’t make me wait too long, Omega.” he murmured before swaggering out of the room.

“Well, you heard him!” Izuku laughed, bubbly as ever. “Let’s get busy, otherwise our boyfriend is gonna have our heads.”

“Yeah,” Eijiro said in a tight voice. “Our boyfriend.”

And if he shed a few tears, Izuku only wiped them away and didn’t say anything at all.
