Swear I don't have daddy issues, I just love this pairing.

Midoriya Izuku walked home in a daze.

This morning had been rough. They'd filled out a sheet on their plans after high school, and of course the teacher mentioned how Izuku wanted to go to UA, the most exclusive hero college in the country. The mockery and ridicule had been no less hurtful for how common and expected it was.

The worst had been Bakugou Katsuki, Izuku's childhood friend turned prime bully. "Like a Quirkless nerd like you could be a hero! Just jump out a window, Deku, and do us all a favor!"

Kacchan, as Izuku still thought of him, had been cruel before, but NEVER had he implied Izuku should harm or kill himself. He wasn't sure if the boy he'd known all his life had really meant the words or was just posturing, but to even say them was a harsh blow. What was worse was that word, the word that had haunted him: Quirkless.

Izuku had long wondered which was worse: that people believed it, or that he couldn't prove them wrong.

Izuku did have a Quirk, one of those powers unique to each person. But it was so small and specialized that he might as well not have one. Like his late father, Izuku had a breath-based Quirk. But rather than being able to breathe anything cool like fire, Izuku breathed out a gas with mild healing properties. It required a good few lungsful to heal even a simple cut. Other than being particularly good at CPR, Izuku had almost no practical use for his skill. When kids mocked him for having no Quirk, he was powerless to deny it. He could hardly ask them to get hurt and spend a few minutes smelling his breath.

But it wasn't the name-calling that had Izuku so out of sorts. It was the news he'd gotten from the nurse, when he'd gone in for a sudden fever and light-headedness.

A few simple questions, a knowing look, a urine sample, and the middle-aged woman had her diagnosis.

Omega.

Midoriya Izuku was an Omega.

Generations ago, when Quirks first started to appear, it became clear that some of the superhuman individuals had certain biological differences in common that couldn't be explained by their relative Quirks. A few years later, secondary genders were just another part of this new society.

Only Quirked people had a second gender; Quirkless individuals remained ordinary on that front as well. Even then, only 1 in 4 presented one of the two sets of characteristics. The other 75%, termed Betas, were simple men and women other than any mutations their Quirk provided. The two new groups to emerge were named 'Alphas' and 'Omegas'.

Alphas, as the name implied, were top of the food chain. They were dominant, powerful, exceptional people with exaggerated physical abilities and the best Quirks. They were extremely virile, in the case of men, and Alpha females became what pre-Quirk society termed 'futanari'. They were the top dogs, the best fighters and leaders the world had ever seen. Bakugou Katsuki, for example, was an Alpha.

Omegas were the exact opposite. They were passive, docile, delicate creatures whom were easily bossed around. Like porcelain dolls, their beauty was only matched by their fragility. Omegas were very domestic, focused only on their Alpha mate and their children. Male omegas, like female Alphas, were hermaphroditic from a reproductive standpoint. They were quintessential damsels.

Alphas and Omegas could fall in love and have kids with Betas and Quirkless. But they were undeniably drawn towards each other. Scientists still struggled to explain the phenomenon of Bonding, but they couldn't deny its power. Bonded were the poster children of happy, loving relationships. Bonded Alphas made for some of the best Heroes, their natural aggression tempered and refined by their Omega's influence. The children of Alpha-Omega unions grew up to become beacons and inspirations, prodigies and natural talents, the top-tier of humanity.

Apparently, Izuku's fever was the warning sign of his first heat, the monthly time of berserk lust when an Omega was most fertile. He'd been given a suppressant, so he could make it through the day, and the number of an Omega specialist to see for general check-ups and birth control.

And that's how Izuku found himself on a wandering route home. He'd been floating in a haze of shock for hours now. He was an Omega. He, Izuku, could get pregnant. He could and probably would end up Bonded, marked and claimed by however many Alphas he was compatible with. That was another thing: Alphas could only Bond to one Omega, whereas Omegas could bond to multiple Alphas. The record was six, though that had involved a set of identical twins and a Hydra Quirk.

Izuku didn't know how he felt. In a way, this explained a lot. He was small, thin, with oddly wide hips for a boy. His temperament was mild, and he was extremely sensitive. He cried at the drop of a hat, and he was so easily scared he half hated himself for being such a coward. When he'd fantasized about boys, or even girls, he'd always pictured himself as taking the passive or submissive role. In that context, he fit the stereotype of an Omega male to a tee. And he did have a Quirk, so a part of him had known this was a possibility. That part wasn't such a surprise. Izuku could accept the physical aspects of his new gender. Honestly, he even liked the idea of bearing and raising children, being a Mr. Mom.

The issue he struggled with was the death of his dream.

Omegas, by law, couldn't be Pro Heroes. It had been deemed too risky. Omegas, it was believed, simply couldn't live up to the physical demands of the job. And the last thing anyone wanted was an Omega going into heat in the field, distracting allies and whipping villains into a frenzy. Plus, claimed Omegas were so jealously protected by their Alpha(s) they rarely left the house or their side, let alone to do dangerous Hero work. It was hard for a Bonded Omega to find ANY job. Repressive and archaic, yes, but the laws had been written by conservative Alphas during the transition period decades ago and had proved remarkably resilient to repeal.

Even with his useless Quirk, Izuku had always dreamed of somehow, someway, becoming a Hero. Since he was a toddler, he'd wanted to be like All Might, the greatest Hero in the world. Saving people, standing up for Justice, protecting the innocent, all with a bright smile. It was all he'd ever wanted. And now that door was unequivocally shut. Midoriya Izuku would never be a Hero. His fate had been decided by his birth. The most he could hope for was to Bond to one and help raise the next generation.

It was a bitter pill to swallow.

Izuku was muttering as he walked under an overpass, voicing his thoughts without realizing. "It's not the end of the world. I can still go to UA, just in the General or Support departments. I can't be a Hero, but I can help in my own way. I could be a nurse like Recovery Girl. And I'll probably end up with a mate or two, though I don't want to go just for that, that would make me a gold digger. But it probably will happen, all those Alphas in one place, even a loser like me would have to find at least one person interested. I'll be a housewife, or househusband, semantics really, taking care of the pups and making sure my Alpha has a safe, nurturing place to come home to at the end of the day. Marrying and mothering Heroes, that's like, a Hero once removed…"

The river of words was cut off when Izuku found his mouth filled with some kind of vile slime.

"Mm, a medium-sized invisibility cloak," came a distorted voice. A monster, that's what Izuku saw. A monster of green-brown sludge, towering over him, binding his body and forcing itself down his throat. "Not to worry, I'm just taking over your body! Calm down!"

Izuku tried to fight back, to flail, to bite, to throw back up the horrible substance streaming down his throat into the rest of his insides. But it was hopeless, the monster as too strong. Tears filled his eyes as he realized he was dying. He'd die, and this monster would walk around wearing his skin, controlling his corpse like a puppet. It was worse than death!

"It'll only hurt for 45 seconds! Then it'll all be over!" the villain teased in mock concern.

'Somebody… somebody!' Izuku silently begged, unable to get any noise past the blockage in his throat. The light began to fade. Panic turned to regret. He'd never see his mom again. He'd never make up with Kacchan. He'd never fall in love, or feel a life move within him. It was too soon, yet here it was. The end.

"I AM HERE!" he heard, as if from a great distance. "TEXAS SMASH!"

And then the monster was gone.

Izuku fell hard to the concrete. He curled on his side, puking the vestiges of the sludge villain out. He gasped for air, each taste sweeter than the last. He probably should have passed out by now, but his body converted some of the oxygen into that healing gas, curing the damage fast enough to prevent him from shutting down.

The 17-year old just lay there. He was alive. He'd been saved. But by who? That voice from before… why had it been so familiar?"

"Hey! Young man!"

Izuku turned, eyes searching, as a broad, warm hand touched his cheeks.

The world shifted.

It was like magnets clicking into place, a jigsaw puzzle being solved, a key sliding into a lock. His whole life, Izuku had been incomplete, waiting, dead. He hadn't known it, but he had been. He knew, because in that moment things changed. Now, with his Alpha here, he was alive. His missing half, his reason for living, had finally found him. His family, his friends, his earthly possessions, all of those were nothing. All that mattered, all that was, was the man before him.

He was perfect. Not just in Izuku's dazzled eyes, the man was physical perfection. A body that made statues of gods seem puny and malformed was crammed into a white t-shirt and khaki pants. A strong, masculine face, with combed back hair that glowed like the sun, two tufts standing up in a 'v' shape. Blue eyes with black instead of white, staring back at him in shock.

It was a face and body Izuku knew as well as his own. He'd been more than a little obsessed with the Hero they belonged to.

It was All Might.

And he was Izuku's mate.

His hero, his idol, his everything, opened his mouth.

"OH, SHIT."

That brought Izuku crashing down.

"A-all Might… I'm sorry. I didn't mean…" Words failed him.

"IT'S NOT YOUR FAULT, YOUNG MAN. IT'S NOT ANYONE'S FAULT." But he was frowning, pulling back the hand on Izuku's cheek to cover his eyes.

Izuku's spirits sank even further. All Might couldn't even look at him. Why would he? Izuku was clearly a disappointment. He was skinny, he had too many freckles, he was male. Not a woman, but not a man either, an Omega freak of nature. Why would someone as awesome as All Might want him as a mate? Well, Izuku wouldn't force him. They didn't have to complete the Bond. He could walk away, let All Might forget him, find someone worthy to be his companion—

"WHAT ARE YOU MUTTERING ABOUT? I'M NOT DISAPPOINTED!"

Izuku flinched. Damn his traitor mouth. But his hero's words filled him with hope. "You… you're not?"

"NO! SURPRISED, YES, BUT NO ONE WAKES UP AND EXPECTS TO FIND THEIR MATE THAT DAY. ESPECIALLY NOT BEING HELD CAPTIVE BY A VILLAIN!"

Izuku remembered where they were then, the circumstances of their meeting. "Oh! Thank you, by the way! That thing was killing me!"

"ALL IN A DAY'S WORK! I'M JUST SORRY YOU WERE DRAGGED INTO MY HUNT. I DON'T NORMALLY MAKE MISTAKES LIKE THAT…" All Might's smile shifted into a frown again. He wiped something at the corner of his mouth. "YOUNG MAN, WHAT'S YOUR NAME?"

Izuku remembered he was lying down. Springing to his feet, he bowed like he was trying to touch his nose to his knees. "I'm Midoriya Izuku, All Might! It is very nice to meet you!"

The blond giant chuckled, but the sound was oddly… wet. "NICE TO MEET YOU, MIDORIYA-KUN! CAN I TRUST YOU?"

Izuku looked up into those intense eyes. "Yes," he swore. This good, honorable man was his mate. Izuku had no idea what he could have possibly done to deserve such good fortune, but it was true. Even without the surge of hormones and instincts still clouding his mind, he knew he would never betray this man.

"GOOD," All Might said. "THEN PLEASE KEEP THIS SECRET." There was an explosion of steam, as if the hero had set off a smoke bomb. Izuku blinked, confused. Was this part of All Might's mysterious Quirk? The mist cleared, and Izuku's jaw dropped. In All Might's place was an emaciated, skeletal man, all skin and bones. And yet, it was still All Might. Still those unique eyes, still that blonde hair (only tangled in a mess instead of straight), and still that kind smile.

If he hadn't seen it with his own eyes, he wouldn't believe it. But Izuku knew, with his rational brain and deep down in his bones, that this was still his mate.

Izuku looked him in the eye. "I promise I won't tell, All Might."

The spindly version of his Alpha smiled wider. "My real name is Yagi Toshinori, Midoriya-kun." He bent down to pick up a bottle filled with green slime. "Why don't I explain while we escort our friend here to the police station?"

Izuku nodded, only to feel his heart stop when blood leaked out his mate's mouth.

"All M- Yagi-san!" the high school student yelled. He rushed forward, every cell in his body screaming to help. "What's wrong? Did the villain hurt you? Did you bite your tongue? What can I do?"

Toshinori looked down at him with a wry grin, which came off more macabre with bloody teeth. "Don't worry, Midoriya-kun. This is normal for me."

"That just makes me worry more! How can you save people with that fearless smile if you have a problem like this?"

Toshinori sighed. "There's a lot of fear behind that smile, young man. Believe me." He wrapped an arm around Izuku's shoulder and began to lead him. Izuku jumped a little at the touch, but soon melted into the embrace. If he were a cat, he'd be purring. It felt so right, being held by his Alpha. And his arm may be thin, but it was warm.

"It happened five years ago, when I was fighting a villain," the hero began.

Izuku reviewed his mental calendar of All Might's exploits. "Toxic Chainsaw? He did this? Was it one of his poisons?"

Toshinori laughed, which worryingly resulted in him coughing blood. "That chump? No, it wasn't him. This fight wasn't made public."

"Who was the villain?"

"… It's better if you don't know. He's still out there. I'll do all I can to keep you safe, but the less you know, the less reason he has to come after you."

Izuku felt himself shiver. Granted, they'd met barely 15 minutes ago, but he hadn't considered all the strings that came attached to being All Might's mate. Still, he couldn't find it in him to be scared. Not walking side-by-side with the man Izuku had always considered invincible.

"So, what happened to you?"

Toshinori reached up to rub his chest, the bottle with the villain tucked safely in his pocket. "I lost a lung and most of my stomach. Between the surgeries to save me and the side-effects of all the drugs, I went from what you saw before to… this."

Izuku's heart wept for the resigned sadness in his mate's voice. "I'm sorry."

"It's not your fault, Midoriya-kun."

Izuku had a wild thought. "Wait! I have a healing Quirk! Maybe we bonded because I can fix you!"

Toshinori paused. "I admire your optimism, Midoriya-kun. But the best doctors and healers in the world did all they could. The chance your Quirk would succeed where theirs and technology failed is… low."

Izuku wilted. "Yeah, no, it was a stupid idea."

Toshinori frowned. He didn't want this young man, so polite and pretty and undoubtedly his mate, to be sad. It rubbed against the grain. "Well… there's no harm in trying, I suppose. Later, though. I have to get this criminal into custody and then have a very awkward conversation with your parents."

"It's just me and Mom. Dad died when I was 5."

"I'm sorry."

Izuku felt all warm inside at the genuine concern. "It's not your fault, Yagi-san," he said, parroting the man's words.

Toshinori's shallow breath caught at the smile Izuku gave him. "Yes. Well… anyway, I can only do Hero work for 3 hours a day, now. I'm terrified of letting people down, that I won't be able to step up and people will die. But I keep smiling, because I'm the Symbol of Peace. The world can't afford for All Might to falter, to be afraid, to be anything less than the best. It's not enough to keep people safe; I need to keep them hopeful too."

"Wow… I never stopped to think how much pressure was on you. You made being a Hero look so easy," Izuku mused.

"It's the hardest job in the world. But it's worth it." Toshinori grinned. Even as a pale shell of the titan people worshipped, Izuku realized that All Might was awesome. And beautiful. It didn't matter what was on the outside. On the inside, he was a true hero. Izuku was excited, scared, just overwhelmed that, for whatever reason, he was All Might's mate. But the longer they were together, the more they talked, Izuku found himself just as glad to be Toshinori's mate. He'd be a good Alpha, a good husband, a good father, just all around a good man.

"Midoriya-kun, you're making me blush."

Izuku flushed. "Sorry, sorry! I mutter when I'm thinking. I know it's annoying."

"On the contrary, I find it adorable."

His face just might burst into flames.

The time flew by, and yet every second was etched into Izuku's soul. They talked about their lives, introducing themselves, getting to know each other. Their bodies had picked each other, but their hearts and minds needed time to catch up. It wouldn't take long, though. They were a perfect match, after all. And they both had hearts of gold they wore on their sleeves.

Izuku watched Toshinori hand over the villain, the chief of the Musutafu police personally thanking the "ordinary citizen" for doing the favor for society. He knew some Heroes had secret identities, but this was something else. It got him thinking.

"How do you do it? Take your old form?"

"You know how a guy with some gut sucks it in to look good? It's kinda like that."

Izuku leaned into his Alpha with a chuckle. Even with stick limbs, he was taller than Izuku. "Seriously."

"My Quirk involves energy storage. I can force my body back to 100%. But again, only for 3 hours a day."

"Does… does it hurt?"

"… Yes. But the world needs All Might. I have to be out there, looking out for the people."

"Who's going to look out for you, though?" Izuku asked.

"A few friends… maybe an Omega," he said, the cutest shy hunch to his shoulders.

Izuku smiled. But then he hung his head. "Mom's going to freak out."

"She doesn't have to know who I am. And I know the age difference is… considerable, but we both know this is right."

"No, no, I didn't mean that. I wasn't planning to reveal your identity anyway. We can just say you look in the Hero industry. And she'd be a hypocrite if she got mad, Dad was a good twenty years older than her. She shouldn't care about the May-December thing. It's just that I only found out I was an Omega today."

"Really?" Toshinori's eyebrows raised high on his triangular head.

"Yeah. I'm sure the school called her, but it'll be a bit much for her that I met and Bonded with an Alpha before I even made it home."

Toshinori blushed. "Well… we're not fully Bonded yet."

Izuku nearly combusted at the reminder. There were three stages to an Alpha-Omega Bonding. First was the scenting. Alphas could smell Omegas and vice versa, alerting both parties to the presence of a potential mate. Second was touch. Physical skin contact allowed for an exchange of chemical markers which provoked a response, the severity of which was proportional to compatibility. Based on the life-changing, all-consuming intensity of their mutual feelings, it was safe to say that Toshinori and Izuku were extremely compatible. However, the Bond wouldn't be complete until the end of the third stage: claiming. Simply put, the Omega's heat would trigger a rut in the Alpha. They would knot, and the Alpha would bite the Omega hard enough to scar. Enzymes would be absorbed into the Omega through the Alpha's saliva and 'secretions' and into the Alpha through his/her… 'spongy tissue' in the Omega's 'orifice'. Afterwards, they would be linked on the most basic level, and have the full advantages of a Bond.

Izuku gulped. Dare he mention it? Before he could overthink it into oblivion, he went with his gut and said it. "Well… we could be. Tonight."

Toshinori stopped in his tracks. "What?"

"Well, the reason I found out today is because I went to the Nurse with a fever and it turns out I was about to start my first heat. She gave me a suppressant but that only lasts twelve hours, so sometime around midnight I'm going to wake up panting and fevered and horny out my mind if the stories are true. I remember worrying about how embarrassing that was going to be to explain to Mom and worried about how I was going to handle it alone, and then this whole afternoon happened, and we met, and we're definitely mates and it's going to happen at some point so why not… tonight?" Izuku babbled, wishing the earth would yawn and swallow him up.

Toshinori had a nosebleed. He reached up to clean it, and for once Izuku was happy to see his mate bleed.

"Izuku…" the sunken man said reverently. The Omega all but preened at hearing his name in his Alpha's husky voice. "We… we don't have to."

Tears gathered in Izuku's eyes. Rejection burned like a hot knife in his chest. "Do you not want me? Is that why you were upset when we met?"

"What? No! NO! That was just from the timing! I would be honored to claim you, Midoriya-kun! I've waited decades for this." The man scowled. "And that's the problem. I'm old enough to be your father. We just met today. I don't want you rushing into this just because you think you must. I… I want you to want me, not as your Alpha but… just me."

Izuku knew what to do. All his usual anxiety and overanalyzing was nowhere to be found. He'd known from the first touch that they belonged, and the hours since as they walked around town had made him want to belong to this man.

He reached up, cupping Toshinori's face. His cheeks were hollow and sharp beneath Izuku's hands, but the skin was warm. And it was Toshinori. In perhaps the boldest move of his life, Izuku initiated a kiss. It was brief, barely more than a peck, but it set Izuku tingling from head to toe. He pulled back, looking up at the surprised Toshinori. The high schooler noted with pride that his Alpha had goosebumps.

"I do want you, Toshinori. You're a good man, and I can't imagine anyone I'd rather be claimed by. Maybe it's too fast, but it's okay. I have a chance to give myself to you tonight. Not in a month, not in a few years, tonight. And I want to take it."

Toshinori kissed him. It was a REAL kiss, with passion and tongue and the most amazing noises coming out of the participants' throats. Izuku had no idea what to do, but he certainly enjoyed the ride. Toshinori pulled back after a solid minute. Izuku was panting, he could taste the coppery spice of blood and Toshinori's essence on his tongue, and he felt curiously wet in his pants.

"Are you sure, Izuku?"

"As sure as I can be."

"You won't regret this." It was an oath. "Whatever it takes, I will make sure you never regret this… my Omega."

Izuku's smile hurt his cheeks. "Tocchan… my Alpha."

For a second, Toshinori swelled up into the muscular form of All Might. Then he returned to 'normal', but he was no less magnificent in Izuku's eyes.

"That talk with your mother is going to be even more awkward," Toshinori said, rubbing his neck. He was still smiling though.

"Let me go first. I should be able to soften her up."

They continued walking to Izuku's home. Would Izuku stay there or move in with Tocchan? Izuku muttered about living arrangements and logistics as they climbed the stairs of the apartment building. Toshinori let him think, internally girding himself for an explosion. How exactly did you tell your future mother-in-law that you had just met her teenage son that afternoon and wanted to stake your permanent claim on him with sex that night?

Izuku had Toshinori wait a few steps away from the door. The man fidgeted, trying to straighten up a little. Why couldn't he have been wearing a suit? Izuku pulled out a key and opened the door a crack. "Mom?"

"Izuku! My baby, where were you? I called, and you wouldn't pick up!" The door was pulled open by a woman with Izuku's face. She wrapped her son in a crushing hug. Toshinori noted that the woman was the picture of health: smooth skin, shiny hair, hourglass figure. She looked more like Izuku's sister than his mother.

"Yeah, uh, my phone was on silent. I wanted time to think."

"Oh, Izuku, I know this is big news. And I'm so sorry you can't be a Pro Hero like you always wanted. But being an Omega isn't a bad thing."

Izuku blushed. "Um, Mom? About the whole Omega thing… I have someone I want you to meet."

The woman tensed. She pulled back from her son, holding him at arm's length. She only just seemed to notice Toshinori. "Oh… Izuku, who is this?"

Izuku shrugged off his mother's grip. He slipped over to Toshinori's side. Their hands intertwined almost without thinking. "Mom… this is my mate."

"Yagi Toshinori," the blonde said, bowing from the waist. "Very nice to meet you, Midoriya-san."

"… Midoriya Inko. Let's continue this inside."

Izuku whispered as they walked in. "This is a good sign. She invited you in. I half-expected her to call the police."

"One of those mothers, huh?"

"I'm still the 4-year old in an All Might onesie in her mind."

"You wore one of those?" Toshinori asked, eyebrow raising.

Izuku went scarlet. "Half of Japan wore one as kids!" he whisper-shouted.

They found themselves in the living room. Inko sat facing them, sat a respectable distance apart on the couch. They still held hands, though.

"How did this happen?" she asked in a neutral tone.

The two exchanged looks. Izuku nodded at Toshinori, prompting him to take the lead.

"I was walking home from getting groceries. I bumped into Midoriya-kun and… I knew he was my mate. It was like gravity moved for me, Midoriya-san. It's not the planet holding me here anymore, it's your son. And, incredible as it is, he seems to feel the same about me."

Toshinori slipped to the floor, bowing his forehead in total submission. Izuku couldn't stop a sound of distress at seeing his Alpha so vulnerable. Inko noted that but kept her eyes on Toshinori. "I know I am probably not what you wanted for your son," Toshinori said, still genuflecting, "I know this is sooner than you would have wanted. But I care deeply for Izuku, and not just because of the Bond. He's a bright, caring, selfless boy I consider it a privilege to have met. If you could find it in your heart to approve our relationship, I would be forever grateful."

Inko considered that, face impassive. She turned to her boy. "Izuku? Is he what you want?"

"Yes, Mom," Izuku said without hesitation. "He's amazing, Mom. He's nice, and he's smart, and he has such a good heart. We only just met, and he feels like my best friend. He makes me happy. I really think I could… fall for him."

Inko closed her eyes. Breathing deep, she refocused on Toshinori. "Yagi-san. I love my son. I want him to have the best life he can have. I want him safe, and happy, and to never have reason to cry. Do your best to give him that, to respect him as a person and not just an Omega, and I will not stand in your way."

"I swear." Toshinori still bowed, like a peasant petitioning a queen.

Inko grinned. "I'll set an extra place for dinner. We're having katsudon. It's Izuku's favorite." She brought Toshinori to his feet and pulled the cadaver-like man into an unexpected hug. "Welcome to the family, Yagi-kun!"

Izuku let out a sigh, tension fleeing him. They had her blessing. The worst was over.

They sat down to eat, the adults striking up conversation. Izuku tried to savor the pork deliciousness, but part of him was worrying about the heat later. Would it hurt? Would he remember any of it? Would Tocchan enjoy it? Izuku was clueless about what to do. He understood the 'tab A into slot B' mechanics, but regarding technique or really any theory he was drawing a blank. He didn't even look at porn, the most he'd done was read one of his mom's adult romances. And there was his mom to consider…

"Izuku, I can hear you."

The boy nearly had a heart attack.

Toshinori was blushing up a storm. 'Ah, about that Inko-san. Izuku, um, well it was really both of us but, he, we figured, given that we like each other so much and get along so well that, erm, given that Izuku will go into heat tonight…"

"Why waste the opportunity?" she finished ironically. "I'm sure teenage horniness didn't influence this decision at all."

"MOM!" Izuku wailed, looking like he'd spent dawn to dusk in a tanning bed.

Inko sighed. "Izuku, you know Matsumi?"

"Matsumi-obachan? Kacchan's mom?"

"Yes. We were friend growing up. She always said that the whole Alpha-Omega thing was nonsense. She insisted she'd never bare her neck and be all 'yes dear' for some random man. Within a week of meeting Katsuki's father, she was planning the wedding. I know how powerful the urge to Bond can be."

"So… you don't mind?"

"Of course, I mind. My baby has a new favorite person, and he's getting all grown up. I just know better than to try and stop it," Inko sighed.

"We can check into a hotel. I certainly wouldn't want to presume," began Toshinori, before he coughed up blood.

"Oh, my god! Yagi-kun, are you okay? Izuku, call an ambulance!" Inko panicked, in remarkable similarity to Izuku's first reaction.

"No, no, I'm fine. It's just a… chronic condition I have," Toshinori explained, conveniently bleeding into his empty bowl. It was disturbing, how good he was at not making a mess. His white t-shirt wasn't even stained.

"Oh! Well, Izuku can fix that up. His Quirk isn't the fastest, but it's very effective! I've kept from becoming a fat house mom just from living near him," Inko praised.

"Mom, it's not just me. You eat right," Izuku protested.

"Ha! Izuku, darling, no woman over 40 eats as much ice cream as I do and stays thin without a little help." Inko got up and grabbed the dishes. "Izuku, take Yagi-kun up to your room, get comfortable. I'll stay over at the Bakugou's tonight. Been a while since Matsumi and I caught up. I'll bring the morning-after pill with me when I come back tomorrow. No making me a grandmother until after Izuku graduates, you two."

"Mom!" Izuku had steam coming out his ears. Toshinori wasn't much better. Though the thought of Izuku round with his baby made him glad his khakis were baggy.

Izuku grabbed Toshinori, leading him away lest his Mom said something that made him actually die from embarrassment. Sadly, his room was not the refuge he hoped it would be.

"Oh, come on!" Izuku exclaimed, when he entered and remembered just how MUCH Pro Hero merchandise he had, especially All Might products.

"Huh. Figures I'd Bond with my biggest fan," Toshinori mused. Granted, with anyone else he'd find this creepy. But Izuku was just such a fluffy bunny that the preoccupation with his Hero persona came off as flattering.

"I… I swear I'm not a stalker or anything. I didn't, like, arrange this afternoon or something! I just really, really, really looked up to you! I thought you were the coolest, and you are even cooler in person and I… I'm shutting up now."

Toshinori tilted Izuku's chin up. "Izu-kun, relax."

Izuku almost dissolved into a puddle at the nickname. "Tocchan…" he whispered.

Toshinori got a naughty grin. "When you call me that, it almost sounds like you're saying 'daddy' (tou-chan)."

"One day, I'll call you that too. And you'll call me 'mommy." Izuku decided that he liked his Omega side. It was certainly a lot smoother than he was.

Toshinori leaned in for a kiss. "I can't wait. You'll look gorgeous pregnant."

Izuku distinctly felt a rush of moist sensation on top of getting hard. "Ew."

"What?"

"Nothing, just… not used to getting wet at both ends yet," Izuku admitted.

"If it's any consolation, you make me hard and leaking too."

Izuku moaned. His eyes tilted down. There was indeed a sizeable bulge, with a faint wet mark at the top.

"Can… can we do stuff before my heat? I… I don't want my first time to be an Omega thing."

"You're a virgin? How, you're so beautiful!" Toshinori was gaping. And hardly believing his luck. His Omega was a virgin. He, Toshinori, would be the first to know the pleasure of Izuku's body, to claim that luscious ass and all the rest.

Izuku looked down. "That's the Bond talking. I'm skinny and pale and hideous."

Toshinori felt his heart break. "No. You. Are. Not. You are so beautiful, with your green curls and cute freckles and big eyes."

Izuku blushed. "Well, you're handsome too, Tocchan," he said, redirecting rather than denying.

"I was," he said, not so much bitter as nostalgic.

Izuku frowned. "No, you still are. Your hair is cool, and your eyes are striking, and you have excellent bone structure."

"That's all I am, is bone structure."

"Yes. And I like it." Izuku tried to make Toshinori see the truth in his eyes. "Then again, I had a crush on Jack Skellington as a kid."

Toshinori beamed. "You're wonderful, Izu-kun."

"Not as much as you are."

"To answer your original question, yes, we can do stuff. We can do anything you want."

"Anything?" Izuku asked, voice jumping up an octave.

Toshinori nodded. "Anything. Forget the Alpha-Omega aspect. For the next few hours, it's just you and me. I'm giving you free reign. If all you want to do is kiss, we can do that. If you want me to make love to you before we rut, I'll do that. If you want to try topping and lose your virginity the 'normal' way, I'll bend over for you. Anything you want, Izu-kun. You're my mate. Body, mind, heart, and soul, we belong to each other."

'Tocchan!" Izuku was convinced. This was Heaven. The Sludge Villain had killed him, and this afterlife was his own personal paradise. So why not enjoy forever with his mate? "Can… Can we take a bath together?"

"Of course."

Before he could second guess himself, Izuku led Toshinori to the ensuite.

"You have your own bathroom?"

"Mom kind of gave me the master bedroom. It was even my nursery."

"That's one doting mother."

"Dad went along with it. Apparently, he cried more than I did the first time he held me."

Toshinori wrapped his mate in a hug. "I'm sorry you never got a chance to really know him."

Izuku bit his lip. "What if our kids never get the chance to know you?"

Toshinori sighed. "I can't promise it won't happen. I can't control the future, and even All Might isn't unbeatable. All I can promise, is to do my damnedest to come home to you each time I go out."

Izuku fought the tears. "I can live with that." The hope from earlier came back. "And I just might be able to get you back to 100%, if my Quirk works on you."

"What is your Quirk?"

Izuku leaned back into his mate. "My mom exaggerated how strong it is. I call it Breath of Life. When I exhale, there's traces of a gas that prompts cellular regeneration. The more a person breathes in, the more it works. But it's slow acting; it takes a few minutes just to heal a papercut."

"Hmm, haven't heard that one before. Is it passive, or can you produce more when you try?"

"Nope, fixed amount. If you'd believe my mom, though, sharing the same air over the years has kept her in peak health."

"I see. Well, I suppose we'll have to wait and find out. I planned on breathing your air for a long time anyway."

Izuku laughed. Then he remembered why they came in.

"Um, do you… that is… can you undress first?"

Toshinori pressed a kiss to those emerald curls. "Of course, Izu-kun."

The Pro Hero walked to the middle of the bathroom, turning to face Izuku. With simple, unashamed motions, Toshinori took off his t-shirt.

Izuku almost screamed.

"Oh, Tocchan! Are you in any pain? Is there anything I can do?"

There was an angry red crater in Toshinori's chest, alarmingly close to his heart. Scars led out from the initial injury, still looking inflamed even five years after the fact. The skin on that side of the torso was lumpy and sunken, where muscle and internal organs had been lost or rearranged. It was a grievous wound, one Izuku could hardly believe his Alpha had survived.

Toshinori shrugged, a smile the Omega could tell was fake on his lips. "No more than usual. You could try to ignore it, if you can."

Tears came to Izuku's eyes. Damn his crybaby ducts. He rushed forward, wrapping his damaged, hurting, perfect Alpha in a hug. He almost received an electric shock, feeling so much bare skin against his cheek and hands. It was a pale echo of that first touch under the overpass, reaffirming the fact that this man was meant for Izuku as surely as Izuku was meant for him. The young man (mostly) ignored it, focusing on comforting his Hero.

"You going to kiss it better?" Toshinori quipped. He was touched by the gesture, though.

"I'm no Recovery Girl. For my Quirk to work, it's best to do CPR," Izuku said, taking the joke literally.

"I'd love to have your mouth on mine. Can we do it in the tub, though? I could use a good soak after a long day."

Izuku pulled away. "Right, of course! Um, I'll… go get an extra stool! There's only one in here."

Izuku left, digging for towels and a bath seat in the closet. When he returned, he almost dropped them.

All Might was waiting for him, hands on his hips, standing there in all his glory. "I AM… NAKED!" he said, saucy smirk on his lips.

Izuku was torn between laughing and lunging. Bronze muscle after bronze muscle met his eye, laid out like a buffet. It was a million times better than the swimsuit issue of Hero Magazine, which Izuku may or may not have tucked under his bed. Better, because having the ultimate Alpha male physique there in the flesh rather than in two dimensions was practically a spiritual experience. And also better, because there weren't any swim trunks blocking the prize from Izuku's eye.

He was definitely drooling. It was bigger than his, of course. He'd have expected that even if they were both Betas; no man could be that confident without packing a little extra. It was perfectly shaped, a proud purple head standing atop a golden shaft. A gentle curve upward, like the blade of a katana, with the hill of the artery on the underside and eye-catching veins on top. It was hairless, except for a well-trimmed bush at the base. Two balls the size of plums hung low and symmetrical beneath.

Izuku didn't know how, didn't care how, but he wanted that 'Pillar of Justice' inside him.

"SAY HELLO TO SMALL MIGHT!"

That tipped the balance. Izuku brought up a hand to cover his mouth as a stream of giggles came out. "That… that's not small, Tocchan. And stop forcing yourself, I don't want you getting hurt from 'sucking in your gut'."

Toshinori shrugged, shrinking down with a trace of steam. "I just wanted you to see the original model before the used clunker you got stuck with."

Izuku felt his heart pang. "Remember, Tocchan, I have a thing for the scarecrow look. And I'm falling for you, your amazing personality, not the frame it comes in." The Omega gave another once over. "Though I will admit, I'm glad Small Might wasn't affected."

Toshinori blinked. "You're falling for me?"

Izuku went atomic red. "Um, well… aren't you falling for me?"

Toshinori walked forward, grabbing the stuff from Izuku's hands. As he did, he gave a peck to those worried, pouty lips. "More and more every minute." He pulled back, an expectant look in his eyes.

Izuku remembered that you can't exactly bathe with clothes on.

Toshinori was unable to believe his luck as his mate hesitantly disrobed. Where Izuku saw himself as skinny, Toshinori saw willowy limbs leading back to a lithe frame. Rather than pale, Toshinori saw ivory skin marked with adorable freckles he wanted to kiss one by one. How the Omega could think he was hideous, Toshinori could not understand. He was stunning, enchanting, like a nymph, an elemental creature that could tempt the gods themselves.

They cleaned themselves side by side, sneaking glances when they thought the other wasn't looking. They washed each other's backs, of course. Izuku noted that even greatly diminished, Toshinori had wide shoulders leading to a slim waist. Toshinori admired the gentle curve of the younger's back, down to the cutest dimples and a truly mouth-watering ass. Izuku ran the bath while Toshinori finished rinsing. They both found themselves sitting side by side, thighs touching, enjoying the warm water as it worked its magic on tired bodies.

"This is nice," Izuku said, truly relaxing for the first time since that morning.

Toshinori wrapped an arm around Izuku's shoulders. He'd done it before, but it was a different experience entirely to do it when both of them were naked. "Couldn't agree more."

Izuku played with the long bang of hair that made up half of All Might's 'v'. "So… what's going to happen after tonight? What will our lives look like?"

Toshinori hummed. "Well, you'll finish up high school and I'll keep doing what Hero work I can. We'll… date, for lack of a better word, learn how to live with each other. We'll spend your heats together, of course, protected as per your mother's wishes. After you graduate, we'll discuss college, if you want to go. Somewhere in there, we'll register our Bond, maybe even have a ceremony and reception."

Izuku blushed. Bonding was considered stronger than marriage, but it still required legal recognition and some Alpha-Omega pairs preferred a big wedding.

"I'm fine with just signing a certificate at City Hall. I never dreamed of a huge affair when I imagined getting married. Besides, Mom already knows, and she's about the only person I'd invite anyway. She can be our witness.

"Do you not have any friends? You don't have to worry about my secret, Yagi Toshinori and All Might have almost zero connection to each other."

Izuku shrugged, looking down into the water. "I'm a bit of a loner. NO one wants to hang out with the Quirkless otaku."

"But you're not Quirkless." Toshinori protested.

"I know. But it's hard to convince people without a demonstration. I gave up a long time ago."

Toshinori sighed. "Nothing crueler than children."

Izuku sniffed. "Amen to that."

"You know… I was born Quirkless."

Izuku almost snapped his neck looking up. "WHAT? How is that possible? You're an Alpha! And the number 1 Hero!"

Toshinori shrugged. "I can't tell you much; I swore to only reveal the whole secret to my successor. My Quirk, One For All, is unique in that it's inherited. It was passed to me before I hit presenting age, and its power was enough to make me an Alpha. Someday, preferably sooner than later, I'll pass it on myself, like a torch shifting hands."

Izuku gaped. "Wow. I never would have guessed."

"I've tried very hard to keep it that way. Apart from you, only my most trusted allies know about One For All. The public just assumes I have an unprecedented Quirk in terms of power."

Izuku's mind raced. "You said it involves energy storage… and it's inherited… it's a stockpile! Every user has added fuel to the fire, before passing it on! The flaw of most stockpile Quirks is that eventually the store runs out, but with the combined energy of all the previous and current users, there must be more than any one person could spend!" Izuku looked up at his mate in awe. "No wonder you're superhuman. You literally have the strength of ten or a hundred or maybe even a thousand at your beck and call!"

Toshinori blinked, shocked at the accuracy of his mate's deductive leap. "Wow. I hope our children inherit your brains."

Izuku blushed. "So I'm right?"

"Indeed. You know an awful lot about Quirks, don't you?"

Izuku bit his lip. "Before goday, when I found out I was an Omega… I wanted to be a Hero. I wanted to graduate UA and spend my life saving people. I know my Quirk is almost useless, but it was my dream. I spent more time studying Pro Heroes, their Quirks and strategies, then I did my schoolwork.

Toshinori grinned sadly. "I see. I was the same. I wanted so desperately to be a Hero, to make a world where everyone could live with a smile. I got lucky, and I'm so sorry we live in a world that won't allow you to live your dream."

Izuku ducked his head to hide his tears. "It was unrealistic, anyway."

Toshinori lifted Izuku up, shifting him to sit in his lap facing him. He was almost distracted by certain parts touching, but he focused on his Omega's teary eyes. "Izu-kun. If my opinion counts for anything, I think you have the heart of a true Hero. And you may not have a job saving people, but know that you saved me from a life of loneliness. I was losing my way, keeping up appearances, nothing but the search for a successor and a life as a cripple afterward to look forward to. You've been with me less than half a day, and already I feel happier than I've been in years. You may never be a Pro Hero, but never doubt that you are my hero."

Izuku couldn't believe his ears. "Tocchan…" A fierce mix of joy, possessiveness, and some powerful emotion he couldn't name flared deep in his core. Determination filled him. "I'm not done saving you."

Toshinori blinked. "Izu-kun?"

The Omega cupped his Alpha's face. "Let me breathe for you. Let me heal you."

"... Okay," Toshinori assented. Why not? He'd said the boy could try.

Izuku leaned in, placing his open mouth over Toshinori's. Breathing in deep through his nose (and getting a dizzying wave of Alpha musk), Izuku let out the air through his mouth. Toshinori took in his Omega's breath, lightheaded at how surprisingly sweet it was. He let out the excess through his nose.

They fell into a hypnotic rhythm, in and out mirrored in each other. Izuku focused as much as he could on making the exchange clean, but the feel of his Alpha's body, the havoc the pheromones wreaked on his concentration, left him uneven at times. Toshinori just relaxed, content to enjoy the hot bath and the strangely intimate act of his Omega filling his lungs with oxygen, CO2 and… something else.

Toshinori's eyes widened as he felt it. A tingling, like pins and needles, deep within his chest. The pain, his constant companion for years, melted before it like ice before a fire. With every breath of his Omega's air, he felt better, less broken, more whole. He started to feel like his old self again! It was incredible. Toshinori almost slipped out of the comforting beat of his mate's inhale and exhale, but he focused. This feeling, he never wanted it to end!

They stayed that way for an hour, the bath turning tepid and then cold around them, but they kept on with their exchange of breath. When the tingling feeling ended for Toshinori, he pulled back. "Stop," he instructed, sensing whatever was happening had finished.

Izuku blinked red spots out of his eyes. "Never done it that long with someone," he mused. He looked down and his jaw dropped. "Tocchan, look!"

Toshinori did, and hardly believed his eyes.

The scar was gone. His scar. Gone. As if it never existed. Toshinori's chest was slim and bronze and perfectly normal for someone as skinny as he was. He looked like he'd never been injured in the first place.

Toshinori took a deep breath, and felt his new lung expand along with the other. He gave a hacking cough, and all he pulled up was mucus, not the waterfall of blood the action should have unleashed. There was no pain. None at all. He felt like a new man.

"Izu-kun," Toshinori breathed out like a prayer. He leaned in and kissed those pouty lips. "You are a miracle."

Izuku blushed, but got a goofy grin on his face. "Your miracle," he fired back.

"Yes. Mine. Mine, mine, mine. And I'm yours," the elder said in reverence.

The moment was ruined by what sounded like the roar of an angry bear.

They both looked down in confusion, before Izuku burst into giggles. "We grew you a new stomach, now it sounds like it wants filling!"

"Apparently," Toshinori agreed.

They both got out of the cold bath, rubbed towels on their wrinkly skin, and put on the underwear they'd worn before disrobing. Then, clad in boxers in Toshinori's case and briefs in Izuku's, they went to the kitchen. Inko had already left, so they had the place to themselves. Izuku heated up the leftovers from dinner and set them on a plate for his Alpha, feeling inordinately pleased to be feeding his mate. He'd have to ask his mom to teach him how to cook. As Toshinori ate, Izuku pictured it. Him, barefoot in the kitchen, wearing an apron, preparing a big feast for All Might who walked in just as everything was finished. The only thing missing from the fantasy was a baby bulge under the apron and another Alpha or two accompanying Toshinori.

Izuku blinked. Other Alphas? What was his Omega subconscious thinking? Tocchan was all he needed.

Toshinori finished off the last bite. "Thank you for the meal," he prayed obediently. Then he turned to Izuku. "Now, what are we going to do now that I have all this energy?" he asked, a glint of something Izuku didn't recognize in his eyes.

"Tocchan?" he asked in confusion.

"I believe you said you didn't want your first time to be an Omega thing. But see, that's really vague. Did you mean your first time cumming from another's touch? Your first time having oral? Your first time topping? Your first time bottoming? It's so hard to tell," Toshinori drawled in a leading way.

Izuku felt his briefs get tight and wet, and experience he was still unused to. "Oh."

"'Oh', he says. Remember how I said we could do anything? I've changed my mind. Tonight, we're going to do everything. And it'll end with my knot in your hole, my seed in your belly, and my teeth in your flesh," Toshinori growled, his inner Alpha an inch below the surface.

Izuku whimpered. And not in fear.

"Get in your bed. Get out of those clothes. And prepare for me to ravish you within an inch of your life."

Izuku shivered. The words hit him like a bolt of lightning. He found himself powerless to disobey. What's more, he didn't want to. He wanted to surrender to this man, this Alpha, his Alpha.

The Omega followed his orders, retreating to his room and stepping out of his underwear. Toshinori stalked after him, grabbing the dropped briefs and holding them to his nose, drinking in the scent of his Omega. His blood burned and rushed and, for once, didn't leak out of his mouth. The horny Alpha dropped the cloth and surveyed the room. It was dark but for a lamp on the desk, illuminating several posters of himself on the walls. He growled with pride, glad that his Omega held him in such high regard.

Izuku was laid on the bed, knees bent, hand on his chest. Hiss eyes tracked Toshinori like he were the wolf about to eat him. Based on the sweet little erection the Omega sported, he was looking forward to being devoured.

"You have no idea how extraordinary you are, do you?" Toshinori growled. "No idea how rare it is to be so pure, so good, so full of light. You are an angel, Midoriya Izuku. You brought back my health, my happiness, my hope. And I will repay you with as much pleasure as your body can withstand."

The scent of slick filled the air. With a groan of raw need, Toshinori attacked.

Toshinori tasted every inch of his mate's mouth, swiping his tongue over every pearly tooth and bit of pink flesh. He pulled back to pepper that cherubic face with kisses, his Omega giggling at the tickling sensation. Izuku stayed pliant and patient, content to let his Alpha run the show. He opened his thighs to cradle Toshinori above him. Small, dainty hands trailed through the straw mop of his mate's blond hair.

Toshinori hummed with pleasure at the small scratches to his scalp. Supporting himself on his knees and elbows, the Hero slid down his mate's body. He trailed kisses, licks, and nibbles down that swan-like neck, pausing to suck right over the scent gland where he'd bite later that night. Izuku whined, his hips canting upward in instinctual desire. Feeling his shaft rub up against the abdomen of his lover was better than any stroke of his own hand.

"Shh, shh. Relax, Izu-kun. All in good time," Toshinori cooed against an elvin collarbone. "You'll have release. Why? Because I am here."

Izuku choked on a laugh. "S-sexy as it is to hear your catchphrase in bed, can't you hurry up a little? Please?"

Toshinori grinned, and took a sugar-pink nipple into his mouth.

"Aah!"

The Alpha sucked, licked, and teased at the peak. The noises his actions drew from the Omega's throat were all the encouragement he needed. His hand came up to work the other with his fingers. The noises got even louder, needier, and more exquisite to Toshinori's ears.

Izuku writhed. Since when had his nipples been so sensitive? Each trace of a wet tongue or warm finger against the little nubs sent a rush down into his chest and to his crotch. To his shock, he recognized the pressure rising in his pelvis. NO way. There was no chance he'd actually… actually… "TOCCHAN!" Izuku cried, as a rush of liquid pulsed out of his length and, to his embarrassment, his ass.

Toshinori froze. The wet sensation against his chest, the ambrosial scent filling the air, the jerking and moaning of the body beneath him, all pointed to one conclusion. "Did… did you cum from just your nipples?"

"Surprised me too," the teen groaned, squirming form the sensitivity of the afterglow. Strangely, though, he didn't feel as exhausted a she normally did after an orgasm. Rather than a rush throughout his body and out his groin, it was more like a storm of energy deep in his bones, rumbling with thunder but the clouds still lingering. It was the difference between a tsunami and an earthquake. "I… I think I'm like a girl now, too."

"You mean multiorgasmic?" Toshinori asked, feeling like Christmas had come early.

"I guess?"

"Let's find out."

Toshinori switched targets, shifting weight to his other arm and planting his mouth and fingers on the opposite side. Within five minutes, Izuku was crying out and squirting again.

Toshinori gathered his mate's release up with his fingers and hungrily licked it off. "Oh, we're going to have a lot of fun with this, Izu-kun," he promised.

Izuku wondered if you could die in Heaven. He just might find out.

The hours passed in a blur of orgasms, driving Izuku half out of his mind with delight, satisfaction, and an ever-growing appetite for MORE. Were all Omegas addicted to sex, or was that just Izuku? He didn't know, and he didn't really care. Toshinori played his body like an instrument, seeking out and finding new keys to compose more melodies of pleasure. Izuku learned things about his body he never would have guessed. Like the fact that having his toes sucked could melt him into a puddle. Or that his prostate was a magical button that transported him to nirvana. Or the way his chest puffed up when his Alpha came on his cock.

They felt it the moment the suppressant wore off. Toshinori growled as the scent of an unclaimed Omega in heat hit his nostrils, coaxing the deepest and most powerful urges out of his brainstem. Izuku moaned, the fire burning through him. It flickered and scorched and popped under his skin, making him itch and ache and want to crawl out of his own body. He burned and only the touch of his Alpha could save him. His Alpha was a balm, a savior, a God. Alpha would take the heat away. Alpha fill him up. Alpha knot. Knot. Alpha!

"Alpha!" Izuku begged. He turned over on his front, lifting his rump into the air. He pulled his shoulders down, making his neck as long as possible. He shook his hips, spreading the smell of his slick into the air. The lubricant dripped and gushed out of his hole, flowing down his perineum to run along his cock.

Toshinori roared, his Alpha crowing to the world his victory. He'd found his Omega, and the bitch was presenting. That dripping hole would take his cock with no resistance, letting him plant his seed deep where it would take root and grow into a pup. With barely restrained savagery, Toshinori mounted his mate. One hand gripped his Omega's hair as the other wrapped around his chest, holding him in place. Pressing every inch of his chest to Izuku's back, Toshinori thrust his throbbing prick home.

Izuku sang his pleasure for his Alpha. He was filled, he was owned. He tightened his hole as best he could, caring only for his Alpha's release. The better he made it, the sooner his Alpha would knot. Knot was important. Knot meant claiming, relief, completion.

The Alpha rutted into his Omega, withdrawing a few inches only to plunge back in to the root, rocking the soft body beneath him with the force of his humping. The Omega whined and moaned and crooned, signaling his submission, his approval, his acceptance of the Alpha as his master, his protector, the sire of his pups. The Alpha growled and barked, expressing his carnal pleasure, his virility, his power over the Omega.

The knot swelled, hot and round and huge near the base of the engorged cock sliding in and out of the tight Omega. With a final lunge, the knot pushed past the ring of muscle, locking the Alpha's manhood into place. Pints of warm, milky seed gushed out, filling the Omega's passage to the brim. With a howl, the Alpha bit into the Omega's neck, parting flesh with sharp teeth to forever mark the Omega as HIS.

The Omega screamed in mixed pain and ecstasy, milking the knot and cock inside him for every drop. For a second, his heart stopped beating. When it beat again, he was CLAIMED. His blood, his bones, his every piece belonged to HIM. His mighty Alpha, the yang to his yin, the master of his universe.

For a timeless moment, they were ONE.

They collapsed on their sides, the knot keeping them from separating, plugging Izuku's hole to keep all Toshinori's semen inside and maximize the chances of conception. The exhaustion of the night caught up with them as the haze faded, and they both crashed into sleep.
