"Omega and Alpha sitting in a tree, K-I-S-S-I-N-G! First comes love, then comes marriage, then comes the omega with a baby carriage."

The bald Omega scowled as he passed a group of children, who were chanting while skipping at the edge of the park. That old nursery rhyme seemed to be mocking his current situation. At the age of twenty-six, and still unmated, his parents had just informed him that he would be brought to the auction house to be sold the very next day. For him, it would be "first comes marriage," he reflected bitterly.

His father had apparently grown tired of waiting for the dowry his family would receive when they married him off, and had likely decided to sell him quickly before the amount they could demand dropped even further. An Omega's "value" dropped after they turned thirty, once they lost their virginity, if they had any scars, just about anything could be an excuse for Alphas to offer a lower price.

Saitama was already unlikely to sell for a decent price. With his strength, and his well-built physique, there was nothing dainty of feminine about him at all. He had hoped his parents would just give up on selling him entirely, and he could just become an old maid. He could be a crazy cat Omega, he liked cats. Once he had lost his hair from being on suppressants for so many years, he had thought that hope would become reality.

He grimaced at the thought that he would be bonded to a stranger..

There were two kinds of bonds that could be created between an Alpha and an Omega. The common one was when the Alpha marked the Omega to claim them. This type of bond would alert the Alpha if their Omega was in distress, and make it so that the Omega was unable to disobey their orders. A one way bond could easily be overridden if another Alpha were to bite the Omega.

It wasn’t uncommon for Omegas that were claimed by a bond bite to be sold or traded when their Alpha became bored with them. Marriage, at least, offered some legal protection.

When an Alpha allowed the Omega to mark and claim them as well, it meant that the Alpha acknowledged them as an equal. A two-way bond also alerted the Omega if their Alpha was in distress, and allowed an Omega to exert their free will, it was also almost impossible to dissolve. It was rare, nearly unheard of, the kind of thing that you read about in stories that had damsels being saved by knights in shining armor.

After circling the block around the park a few times did nothing to calm his agitation, he set off toward his usual hang out. The Omega was just itching for a fight to blow off some steam, so it was time he paid Fubuki another visit.

Miss Blizzard, as she was called, had her fingers in just about every technically legal, yet unsavory business in Z-City. After dark on a Friday night, she could be found at the Fight-House. It was a bar that was geared toward Alpha customers, with a boxing ring in the middle. Legal fights could be organized there on short notice. A minimum of ten minutes' wait was required after a challenge was accepted so that bets could be placed, and then the competitors were free to hit each other as much as they wanted. Matches would end if one of them was forced out of the ring, lost consciousness, or admitted defeat.

Most larger towns had one these days, as they were considered a good way for hot-headed Alphas to take their aggression out on each other. Being a place where all presentations could go to watch matches, drink, and socialize also helped.

It wasn’t entirely safe. Injuries were common, occasionally he even heard news stories of fighters that had died, but he knew from experience that it was a hell of a lot safer than getting into street fights. Hell, something as innocuous as walking down the street had landed him in a life-or-death altercation once. Even before he became so strong that he stopped losing matches, he had been fine with the risks. He’d rather be in pain, than be bored, anyway.

The higher ranking and more popular fighters often quit their day jobs, in order to fight professionally. The top among them lived quite comfortably off of their prize money, endorsement deals, and by getting paid to make appearances in Fight-Houses outside their local area.

Luckily for Saitama, you didn't, technically, have to be an Alpha to step into the ring. With his strength, and scent blockers, most of the other patrons just assumed he was one. On occasion, someone would point out that he was a bit on the shorter side, or that his shoulders weren’t quite as broad, but they assumed that he was a Beta. It didn’t occur to any of them to even consider that an Omega could hold their own in the ring.

Fubuki knew the truth of course, but she hardly cared, when he fought, bets were placed, and she made money. As far as she was concerned, that was all that mattered, and Saitama’s matches always made her a lot of money. Despite the fact that he hadn’t lost a match in years, and had mostly managed to avoid stirring up any drama, the general audience seemed to really dislike him. The many bets made against him for his every match, only served to line her very deep pockets.

He didn’t really care about his reputation, he just fought because he wanted to. Although a small part of him sometimes thought it would be nice to have fans, it didn’t bother him to be considered a heel.

When he arrived at the bar, he casually strolled past the line of customers waiting to be let inside. The bouncer simply moved aside to let him pass. He was well known there, undefeated for three years running would do that. He would be the top ranked fighter at that location, if popularity hadn’t been worth a third of the score.

As he strolled past the ring, he glanced at the fight that was already in progress. Two hulking Alphas in tank-tops were exchanging blows. Saitama frowned slightly, neither of them looked strong enough to give him an interesting fight. He hoped Fubuki would have something better for him that night.

He ignored all the betting going on around him, and made his way to the stairs that led up to the VIP area. She would most likely be up there, with her stack of release forms. Those slips of paper were the difference between an illegal drunken brawl, and a legal organized fight. The bouncer in front of the steps gave him a nod, and moved aside to let him pass.

"Saitama," the dark green haired Beta waved him over when she saw him. "I figured I would see you tonight, after the meeting I had with your parents earlier." The Omega frowned and took a seat across from her. Of course his parents would be selling him through her auction house. As if being sold wasn't bad enough, his new Alpha would probably be someone he'd fought, and won against in the past. Just fucking perfect. Hopefully, whoever it was, wouldn't be the type to hold a grudge.

"Can't you refuse to sell me? Or just buy me to work for you?" He asked, even though he knew it was a long shot.

"Look, I'm not exactly thrilled to be selling off my best fighter... you do bring in a lot of money..." The Beta admitted, knowing that she made more betting on him in the ring than the percentage the auction house would earn for the sale, "but there are other considerations. Your parents insist that you be sold to an Alpha and bonded. If I don't handle it, they could take you to a... less reputable auction. This way I can at least reject the bids from anyone who would be a problem."

Saitama sighed. He knew his mother at least was adamant that he be bonded. After his hair fell out from being on suppressants for so long, she had begun harping on him about how he needed to stop taking them. Marrying him off was her misguided way of taking care of his health. Fubuki was only trying to help him make the best of a bad situation.

The Omega really didn't have any options. He had heard enough rumors about what happened to those who were sold through the sketchy auctions to know that he was better off in Fubuki's hands. At least she would do a criminal record check, and she could weed out the Alphas that were holding a grudge. If she refused to help sell him, who knew where his father would bring him. That man wouldn't care as long as he got his money.

"Whatever," he grumbled, feeling defeated, "just try to set me up a fight with someone tough for once, I could use a little fun."

He wondered if getting drunk first would be enough of a handicap to make the fight last more than a few minutes.

"I have to do what!?" The blonde snapped, his black and gold eyes flashing with anger.

"You have to get married, Genos," Dr. Kuseno, his adopted father replied softly, "to a female or an Omega who can produce an heir for you."

The blonde ninteen-year-old growled under his breath and began to pace back and forth between the rows of equipment in the lab. The doctor's nephew Amai had always been a smug, conceited little shit, but they had never imagined that he would challenge Genos' right to inherit Dr. Kuseno's lab and research. The blue-haired pain in the ass was a successful fighter as well as an idol, with a fortune of his own, and a harem of females. What reason could he possibly have to want to get his hands on the equipment and research the doctor had spent his lifetime working on?

Whatever it was, it couldn't be good. He couldn't be allowed to have it, and yet... Genos had never, for as long as he could remember, felt the tiniest amount of romantic or sexual attraction to a female, or an Omega. Not even the scent of an Omega in heat had ever stirred his interest.

He had only ever felt that kind of attraction to male Alphas, and maybe the occasional male Beta. He was drawn to their strength, masculine physique, and their strong-willed personalities. In short, he was gay. Not only interested in the same gender, but mostly the same presentation, and his dad was one of the few people who knew.

Dr. Kuseno's expression was grim. He knew exactly what kind of sacrifice he was asking his boy to make. The obvious empathy in the old Beta's eyes, was enough to drain all the fire out of the teen's temper.

"Can't I just marry an Alpha, and adopt an heir? You adopted me." He asked pleadingly. Hoping to find some way out of this situation.

"I'm sorry my boy, but pack inheritance laws are clear as they are archaic. If you don't marry a partner who can bear blood-related offspring, as the Alpha closest related to me by blood, he can claim the rights to all of this." The old Beta gestured around the lab, pointing to the high end prosthetics, powerful computers, and dangerous experimental weapons that were scattered about at different work stations. "I know how you feel, but I adopted you, because you, of all people, can understand the importance of keeping my research out of the wrong hands."

The blonde Alpha looked down at his gloved hands, knowing all too well the truth of those words, and feeling utterly defeated. When he was only ten years old, Dr. Kuseno's lab assistant had snapped, and taken technology from the lab, before going on a murderous rampage. The deranged man had burned the boy's hometown to ashes, killing his family, and leaving him as the only survivor of that tragic night. Reporters who covered the event would later dub the man, The Mad Pyro.

Even though it had been used for great harm, the doctor's research could be used to do great good as well. When the Beta had found the boy amongst the rubble, he had rushed him to his lab, and used the medical technology he had there to save his life. When his eyes, major organs, both of his arms, and legs from the knees down, could not be saved, the doctor had fitted him with top of the line prosthetics, and artificial organs. They interfaced directly with his nervous system, allowing him to live a normal life despite the amputations. His recovery from the brink of death, had been grueling, but it would have been impossible without the doctor's experimental technology

At first, the Alpha had been obsessed with getting stronger, to find the Mad Pyro and get revenge. It seemed that fate had other plans for him. Long before he was in any condition to even consider going after his enemy, the maniac had been killed during one of his attacks. Genos had wanted to at least be able to thank the person who did it, but for some reason their identity was protected, and he couldn’t get any information about who it was.

From that time forward, they had both put their energy into improving the medical technology the doctor had created. Genos has proven himself to be highly intelligent and learned quickly as they worked together.

His experience with actually using the tech, and eagerness to use himself as a test subject, proved invaluable when trying to make modifications to improve quality of life and functionality. Their research saved and improved countless lives.

The Alpha brooded in silence for a while, and the doctor, having grown used to his moodiness over the years, sat nearby and tinkered with one of their recent projects. Genos was grateful for the quiet comfort that the old Beta provided while he came to terms with his fate.

"I can’t force myself to have feelings for someone, but I suppose I don't have a choice. I will do what I need to, get married, support them, help them through their heats, and raise children together. It could be... a kind of business arrangement. Still... If I can have at least this much choice, I would rather marry a male Omega."

The old Beta gave him a pat on the shoulder. "You're doing the right thing my boy. I'm proud of the man you have become. How about we go to the auctions, and pick out your mate tonight?"

The Alpha cringed, he knew there wasn't much time, but he didn't think that he could bring himself to make that kind of choice without having more time to get used to the idea. He would more than likely reject them all. The way Omegas are presented at the auctions, in flowing robes, and heavy makeup, long hair flowing loose... He would probably run out the door and never look back.

"Just pick whichever one you think is suitable, I trust your judgment." He replied, it didn't matter to him really, none of them would be what he really wanted. "Just please put it in the agreement that they wear a suit instead of a dress for the wedding."

Chapter Text

When his parents had dropped him off at the auction house, Saitama's Mother had been almost unbearably excited at the prospect of him being married. The entire drive there, she had one on about how he would soon be "living a life of domestic bliss," and "raising her adorable little grandbabies."

The Omega had tried his best to ignore her as she prattled on, turning to gaze blankly out the window. If he was this bored just listening to what it would be like to be someone's house Omega, he didn't want to think about how boring it would be to spend the rest of his life that way. He knew that it was pretty much a guarantee that his Alpha would not allow him to continue fighting, but he hoped that he would at least be allowed to have a job. Sitting around the house, cooking and cleaning was a nightmare to him, the monotony of it would probably drive him crazy.

Things didn't get any better for him once he arrived at the auction house. His parents had simply dropped him off along with the other Omegas that were milling around outside the large building's double doors. His mother gave him a quick hug, and his father barely grunting a goodbye before they took off, leaving him in the hands of the staff who ran the auctions.

Saitama looked around, there really wasn't any security, no chains, or bars to keep him there. For a moment he considered running, but then, where would he even go? Omega's couldn't get jobs, rent an apartment, open a bank account, or even get a license without a guardian's permission. He had only convinced his mother to let him start going to the fights, because he had been caught getting into street fights, and the Fight-House was a safer alternative. That, and he suspected she was hoping he would meet a nice Alpha. His father had agreed, because his prize money went into his parent’s account.

Most importantly, he couldn't get suppressants without his parents to sign off on them. He couldn't exactly go without. He had managed to avoid being bitten on the neck and bonded, mostly just by not looking like an Omega. Going into heat wasn’t exactly something that would fly under the radar. At least if they bought him at Fubuki’s auction it would mean they had the finances to support an Omega, and nothing on their criminal record. Nothing was physically keeping him there, but he couldn't just leave either.

After they had all arrived and been accounted for the staff broke them up into groups. "Experienced Omegas," and virgins were separated, and then they were split into groups of males and females. Males, being less common, made up less than a quarter of the Omegas present, and only four of them were virgins.

As the groups were ushered into changing areas, Saitama couldn't help but to notice how he stood out like a sore thumb compared to the other three. The others were barely above eighteen years old, the minimum age that an Omega could be auctioned. They had long flowing hair, slender figures, and delicate features.

One of the others sniffed in his direction. His scowl, and a quiet growl had them backing off quickly, a fearful look on their face. On the one hand, he should probably have felt bad for scaring the kid, he -really- did look out of place. On the other hand, obviously trying to scent a stranger was just rude.

The small group was ushered into a changing room by a strict-looking female Beta, with her hair tied up in a tight bun. "Put these on." She said in a no-nonsense tone as she pushed bundles of white, silky cloth into their hands on the way through the doors. "I will be back in five minutes to finish getting you prepared."

The small room was mostly empty, except for a large mirror that covered most of one wall, and a vanity with a little stool against the opposite wall. The vanity's mirror was rather large on it's own with lights around the outer edge. Saitama eyed the massive makeup kit that sat on top of it, not at all looking forward to when it would be his turn to be seated in front of it.

He sighed, and unfolded the bundle of cloth that he had been handed on his way in. The other three were almost done getting dressed already, and he didn't want that pinch-faced beta to get on his case about wasting time.

The outfit turned out to be two pieces, the silky white pants fit well enough, so they weren't so bad. The long-sleeved flowing robe that he was supposed to wear over them, however, looked entirely too feminine.

He glanced at the others, who were already changed and admiring themselves in the large mirror. He had to admit, they did look pretty. The silky, flowing fabric perfectly complemented their soft features.

The robe didn't exactly have the same effect on him. It was loose where it should have been tight, and tight where it should have been loose. He worried if he moved the wrong way the whole thing would come apart at the seams. He wondered if he would be charged for ripping it.

On his frame, with his masculine features, it just looked wrong. He frowned at the mirror, he wasn’t as noticeably buff as the Alphas he competed against, appearing to have an average build when he was wearing his typical baggy clothes, but he had a decent physique. He had to workout daily for years to achieve his visible abs and toned arms. It seemed wrong to put what was basically a dress over the masculine body he had put so much effort into.

When the Beta returned, she looked them over with a smile. "Now that you're dressed, it's time for the most important part, hair and makeup. Let's get you Omegas looking your best shall we?" She cast a pointed look at Saitama as she spoke, and he scowled back at her. So what if he didn't have hair?

He was handed a form to fill out while he waited for it to be his turn to have his makeup done. It had a few questions for things like what were his hobbies, allergies, and other things a potential Alpha might want to know. He filled it out quickly, not really putting much thought into his answers. He spent the rest of his time bored, staring blankly off into space.

Apparently he was the last one, because when the pinch-faced woman got his attention, snapping him out of his daze, the others had already left. She didn't say anything, but the look on her face was all he needed to tell him that he had been left until last because she thought he needed the most work.

He took a seat on the stool, and frowned at their reflection as she got to work, coating his face in layer after layer of makeup, until he looked like some kind of plastic doll. "I don't even look like me anymore." He muttered, as he turned his face to each side, examining cheekbones that had not looked nearly so prominent before.

"It's called contouring," she replied bluntly, "you should look it up."

Before he could come up with a retort, the door opened and Fubuki strode into the room. She quickly dismissed the other woman, saying that she would be handling Saitama from then on as he was "a unique case," and she wanted to make sure that he sold as quickly as possible.

As soon as the other woman was gone, the Omega turned to Fubuki and gestured at himself. "Please tell me I don't actually have to go out there like this."

"Omegas do have to wear the robe for the auction, and having your makeup done is mandatory." She started, but then pulled a pair of scissors, out of her pocket, and grabbed a package of makeup removing wipes off the vanity. "They are however allowed to make modifications that allow them to showcase their own unique appeal."

Saitama breathed a sigh of relief as he took the items. "Thank you."

"Just make sure you don't do anything that might make you look like anything other than a traditional, dainty Omega," she said with a grin, "if you do, you might be waiting here for weeks, maybe even months, before anyone bids on you at all."

Saitama grinned back as he realized what she was up to. Omegas who were brought to the auction house lived there, on the upper floor of the building until a suitable offer was made. It was only once a week, every Saturday, that they would be brought down to the main area where the public would be able to view them and make bids.

"Of course not." He replied in mock indignity, "I would never do anything that would make me look like any less of a delicate little flower."

Chapter Text

Dr. Kuseno arrived at the auction late in the evening, after the sun had set. He had been working on an experiment for most of the day that couldn't have been left unattended. He knew it had been mostly an excuse to wait until the crowd had thinned a bit, Genos was more than capable of handling things on his own. The old Beta simply didn't have the patience for crowds and noise, he much preferred the quiet near-solitude of working in his lab. With it being a silent auction, it really didn't matter what time he arrived anyway, and he was more than confident that his pockets were deep enough to guarantee he would make the highest bid on the Omega he selected for his boy. Genos deserved only the best after all.

At the auction, the Omegas were seated in chairs in little booths, with their information, and a locked box with a slot on top set on a table in front of them. If a buyer saw an Omega they liked, they would write their offer, and their information on a slip of paper and place it in the box. Then, the Omega would be sold to the highest bidder, so long as they were deemed fit by the auction house.

By the time he made his way through the large double doors, there was hardly anyone else making their way along the rows of booths that contained the Omegas. The doctor made his way to the last row on the left, where the males could be found. The first three were dressed in white, meaning they were virgins, and the rest of them were wearing the red robes that signified that they were "experienced."

As the Omega would be bought for marriage purposes, he supposed it would be preferable to get a virgin, if only to ensure no former mate would come nosing around, and making trouble. The three that were dressed in white, however, did not seem like they would be of any interest to his son. They looked more or less alike, all equally soft and beautiful, laying across their chairs in sensual positions to catch the attention of potential Alphas. The only real difference between them being the colour of their hair and eyes. Perhaps it was a trick of the makeup?

Rather than choose from the limited options among the virgins at the front of the row, he decided to continue looking. Perhaps one of the others would be more suited to his boy after all. What did it really matter if they had been mated before? He would be willing to accept any trouble that came with them, so long his boy was happy.

He didn't see anyone who looked right among the red-robed males either. They were indeed all beautiful, some more curvy than petite, which fit his own personal taste much better. Perhaps it would be good for him to have a partner of his own around, he mused, then decided that it was a consideration for another day.

He continued until he reached the first empty booth and sighed. He had been hoping against the odds, that he would find someone that would be suited to his boy's sense of taste. Without really thinking about it, the old Beta found himself wandering further up the row, eyeing the empty booths, as if, by some miracle, he would find what he had been looking for.

When he reached the very end of the row, he stopped and blinked for a moment, wondering if perhaps he was having some sort of hallucination. Then he checked the paper on the table, just to make sure that he wasn't looking at an Alpha or Beta who had gotten tired and fell asleep in one of the booths for some reason.

The Omega, Saitama, as the paper said, was sprawled across the plush chair, sleeping. The sleeves, and material below the hips on the robe had been cut away, making the outfit resemble a kind of silky martial arts uniform more than a dress. He was bald, and his face (which the doctor noted was not wearing any makeup) was rather plain. Dr. Kuseno didn't think that it would be a problem, considering his masculine figure.

Curiously, he glanced over the other information contained on the Omega's file. "Hobbies: Training and fighting. Special talent: Punching things." A wide grin spread across the old man's face. He hadn’t dared to hope he would find an Omega that would be so well suited to his boy's tastes.

He picked up one of the slips of paper, and made sure to write down a very generous offer. He needed to be certain that his would be the highest bid, he doubted he would come across another Omega quite like this. Genos was certainly in for a pleasant surprise.

Chapter Text

When Fubuki had broken the news to Saitama the day after the auction, that a surprisingly large bid had been made on him the first night he could hardly believe it. All he could think to say was "You're kidding right?" Unfortunately she was serious, and so was the buyer. Apparently some family was dealing with a dispute over inheritance, because the Alpha was adopted or something. He hadn't really been paying attention while she explained it to him. All that really mattered was that she couldn't find any reason to reject the bid, and his parents had been more than happy to accept it.

Even worse, because it was being done for legal reasons, they had insisted that the wedding take place as soon as possible. It had already been arranged to take place the following Saturday. So much for delaying things for as long as possible. He would be staying at the auction house for only one week, to ensure that his "purity" wouldn't be "compromised" before the wedding. That wasn't nearly enough time for Saitama to get used to the idea.

Despite how boring it was to stay in a room at the auction house, and how his mother would visit to talk about wedding arrangements for what felt like an eternity, his last week somehow passed all too quickly. When Friday came, all he could think of was how he was going to be married off the next day. He wouldn't be able to fight anymore, he might not even be allowed to train. Someone he didn't know was about to be handed full authority over his life.

He had spent almost the entire day in bed, staring at the ceiling, and feeling sorry for himself when Fubuki had busted into the room. She threw his yellow suit, white cape, along with matching red boots and gloves at him, startling him out of his depressed daze. "Get changed, we're going to The Fight-House."

He looked at the costume that he wore for his fights, then back up to her. "But I'm not supposed to go out before the wedding?" It was more a question than a statement.

"You're not supposed to go out without proper supervision. I count as supervision." She explained. Saitama was pretty sure that the loophole in the rules that let Omegas go out if supervised was not intended so that they could go get drunk and get into fistfights, but he wasn't about to argue.

"Because tonight is a special occasion, I invited a strong Alpha from out of town. She goes by 'Mosquito Girl' and she's undefeated." The Beta said, sounding rather pleased with herself. "We're throwing you a bachelor party in the VIP section, and you're going to end the night with a fight, before I drag you home good and wasted."

Saitama grinned and got changed, not caring that she was in the room. He had thought he would never step into the ring again, and she had gone out and found a promising opponent for him. It would probably be his last fight, so he really hoped this bug lady or whatever would be good. He would probably be good and wasted before the fight, considering how notorious Fubuki's parties were, so maybe it would last a while.

The bar wasn't far from the auction house, so they decided to walk. Being cooped up all week, the Omega was happy for an opportunity to stretch his legs anyway. He took deep breaths of the cool night air, savoring his last night of freedom.

When they arrived, and made their way up the steps to the VIP area, he found that most of the bar's regulars were already there waiting for him. Some guy who wore a giant lobster costume pushed a beer into his hands as he took a seat on one of the couches. He honestly didn't remember half their names, but he couldn't help but to feel a bit touched.

"Alright, let's get this party started!" Fubuki called out, signaling the DJ to hit the music.

***

The entire week leading up to his wedding, Genos had been filled with dread. He had left all the arrangements to his adoptive father, not wanting to think about it. Unfortunately, it was still the only thing on his mind. Dr. Kuseno seemed to be confident that everything would work out, but he couldn't ignore the pit he felt in his stomach every time he thought of what it would be like to be mated to some pretty little Omega that he had never met. He hoped they weren't expecting some romantic, fairy tale style, happily ever after.

He couldn't really see himself wanting to be any more involved with them than he would be obligated to. Separate bedrooms would be a must, he had already selected one of the guest rooms for them to take over, as far from his room as possible. Hopefully they had a hobby, or would want to work outside the home. If they didn't, he would just have to start spending even -more- time in the lab.

He had spent most of the day before the wedding in the weapons testing area of the lab, shooting targets, trying to ease the frustration that just wouldn't go away. That was where his friend Satoru, and his obnoxious boyfriend Sonic found him.

"Yo Toaster! Get your shit together, we're going out!" The long-haired Beta yelled at him through the speakers that allowed onlookers to communicate with him from the other side of the blast-proof glass.

Scowling, Genos stormed his way over to the door that led to the observation area, jerking it open, then slamming it behind him. "What the fuck do you want?" He demanded, not at all in the mood for any of the annoying Beta's shit.

"Woah, save that aggression for the ring Genos," Satoru said, trying to de-escalate the situation. "We made plans to go out tonight, remember? For your bachelor party."

The blonde teen felt his hostility lessen a bit at that, though his scowl stayed fixed firmly in place. Now that he thought about it, he did remember making plans to go to the Fight House with Satoru. It really wasn't like him to be forgetful. Getting out would probably do him some good, and he could consider it a field test for his prosthetics. He wondered if he would be allowed to get into the ring, considering his enhancements. He was just itching for a fight, and Satoru probably wouldn't appreciate it if he punched his boyfriend's smirking face in, or lit his stupid purple scarf on fire.

He quickly got ready to go out. He put on a long sleeved shirt and gloves to cover the black, synthetic skin of his prosthetics, and a pair of dark wrap-around sunglasses. For the most part, people seemed to find his black and gold eyes off-putting, and he didn't feel much like having to explain his tragic past to every random person at the bar.

He spent the drive in sullen silence in the back seat, while the couple in front had one of those sickeningly sweet, lovey-dovey conversations that made him feel like a third-wheel. He couldn't be happier to get out of the car when they finally arrived.

He could hear the beat of the music from outside, and a line stretched down the block. It looked like it would be quite the long wait. Genos started toward the back of the line, but Satoru motioned for him to follow after him instead, and lead them right up to the bouncer. The burley Alpha guarding the door gave a high five to the glasses clad Alpha “Hey Mumen Rider,” and waved the three of them through without question.

Satoru was so humble, it was easy to forget that he was actually the most popular fighter at this location. He was far from the strongest (though he did earn his fair share of prize money taking on lower-ranked opponents), and he wasn't the fastest either (that would be his jackass boyfriend, who despite not being an Alpha was apparently allowed to fight there too), but because he never gave up. He always stubbornly refused to tap out, insisting that he continue until he either won or was incapacitated. He had earned the respect of just about everyone he met with his will to go on. He was known for having nearly bottomless patience and kindness. The volunteer work he did to help the community, as well as the charity bicycle marathons, didn't exactly hurt his reputation either.

Considering it was where his best friend went for work, as well as fun, and it was filled with strong Alphas, it seemed a bit odd that he had never bothered to go there before. Then again, his focus was always on helping Dr. Kuseno at the lab, it had taken years of research just to understand a fraction of what went into creating prosthetics with functioning sensory perception. He hadn't left very much room in his life for going out and socializing.

When they stepped inside, the first thing he noticed was how dimly lit it was. He was grateful he was able to turn up the brightness of his visual input, rather than having to remove his sunglasses. The music was loud, with an intense beat, and different coloured lights pulsed to the music.

"It isn't usually like this," Satoru explained, raising his voice to be heard over the music, "but Fubuki is throwing a bachelor party for our local champ. It's convenient for us anyway, I can get us into the VIP area to party with the bigshots."

Genos resisted the urge to point out that just celebrating with him was already partying with a bigshot and just went along with it, as he was led to the stairs.

There certainly seemed to be quite the raging party going on, and Genos quickly found himself swept up into it. After a few drinks they brought over to the owner to see if he could step into the ring.

The female Beta waived as they approached. "Hey Mumen, what took you so long to get here?" She was draped sideways across her chair, apparently already pretty hammered, it seemed that almost everyone there was partying pretty hard that night.

After exchanging some small talk with the woman, and asking her to pass along his best wishes to the guest of honor, Satoru brought up the subject of Genos getting into the ring. She agreed, interested to see if his mechanical parts gave him any advantage. She then insisted that his fighting name be "Demon Cyborg," and that he wear a sleeveless top as well as remove his sunglasses when he got into the ring.

Maybe it was just because of the alcohol in his system, or maybe it was because most of the people around him were dressed in some ridiculous costume for when they stepped into the ring, but he found himself easily agreeing to her terms. It seemed that all the higher-level, or more popular fighters had some sort of gimmick. Apparently even Satoru got dressed up for his fights, though he just wore the same thing he wore when he was out cycling. They probably wouldn't even question his unusual appearance.

"I have one slot left anyway, you can fight Mosquito Girl in the second-to-last fight. If you beat her, that means you fight Caped Baldy." She explained, "We want him to have the strongest opponent possible tonight." He didn't know if he should be impressed at how she managed to get him to fill out the waiver, and talk business while she continued to down shots.

It was just as he had finished signing his name, that a spotlight shone down on the ring, and the music was turned down, signifying it was time for the fights to begin. He watched with interest as "Mosquito Girl" was announced, and stepped into the ring. Her first opponent didn't last long, nor did the second. Still, he felt fairly confident that he could beat her. In her ridiculous, revealing bug costume, she didn't look all that tough.

***

It was only after she had somehow managed to do considerable damage to his prosthetic limbs, and thrown him into the air like a rag-doll, that he admitted to himself that he wasn't going to be able to win the fight. He had been too confident going into it, she had used it against him. In spite of her insane outfit, she had proven to be an experienced and capable fighter. With what little motion was left in his right arm he tapped out. He was incapacitated anyway by that point, his left arm, and both legs were totally shot. It looked like Satoru and Sonic were going to have to carry him to the car.

He made a mental note to apologize to Dr. Kuseno when he got home. The Old Beta would probably have to work through the night to get him fixed up in time for the ceremony the following day. He knew he deserved the lecture about being reckless that he would receive while being fixed up.

He asked his friend to prop him up in one of the chairs so that he could watch the last fight before they left. "Yeah, sure. This isn't going to take long." The other Alpha had replied. Mosquito Girl was quite the contender, he didn't doubt that she would be able to defeat her opponent swiftly.

"And now the moment you've all been waiting for! Stepping into the ring is our local undefeated champion, Caped Baldy." The announcer's voice was greeted with boos and jeers from the crowd. Apparently the guy wasn't well liked.

"I told you not to call me that!" a bald man in a suit that resembled yellow onesie pajamas with a cape, red gloves, and boots, yelled, shaking his fist at the announcer as he stepped into the ring. He looked to be about average height and weight for a male Beta, hardly intimidating compared to the other fighters he had seen that night. Genos snorted, he was certain the fight wouldn't even last a minute."

He had been correct in a way, the fight was over in a few seconds. If he had blinked he may have missed it. The moment the bell had rung, the bald man had stepped forward and delivered a devastating, open-handed slap to her face. The sheer force of it had knocked Mosquito Girl out of the ring, and she made no move to get back up.

"Heh, bugs suck." The victor joked. Then he looked down at the woman who was lying dazed on the floor. "Maybe I overdid it though, that fight was kinda anticlimactic."

Genos couldn't help but be amazed by the incredible strength of the bald man. He didn't think he had ever been so immediately attracted to someone in his life. He wished he could get closer to him. It was too bad, really, that his soon to be mate couldn't be someone like that.

Chapter Text

The next morning, Saitama was startled awake when his unbearably excited mother flung open the curtains in his room. The brightness instantly set off a pounding in his head. The hangover brought with it memories of the night before, and unfortunately, the realization that he was about to be married to someone he had never met.

"I can't believe you would sleep in today of all days," even while attempting to nag at him, she had a cheery smile on her face, "and where is Fubuki anyway? Isn't she supposed to be helping us get you ready?" Given how much they drank the night before, she was probably sleeping off her hangover, he wished he could do the same.

As his mother began to rattle off the plans for the day, his longing to go back to bed only intensified. She was dragging him to some spa to get a facial, manicure, pedicure, and other beauty treatments. Then it would be off to where the wedding was being held, where he would get to see what he would be wearing for the ceremony.
That thought alone made him cringe. His mother had been showing him pictures of bridal gowns all week. Talking about how they would cram him into a corset to give him a more feminine figure, and put a veil on him, that would make him look "sweet and delicate."

The ceremony was going to take place in the afternoon, and then there would be a reception dinner, followed by a party that would last well into the evening. It was going to be a long day.

The omega let out a sigh, rubbed the sleep from his eyes, and dragged himself out of bed. No point in delaying the inevitable, he might as well get the day over with. He allowed his mother to drag him out to the car, not even bothering to change out of his pajamas. He hoped that there would at least be time to stop for coffee before they got to the spa.

***

By the time they arrived at the church, Saitama was thoroughly tired of being "beautified." Thankfully, his new alpha preferred a "natural" look, so they had only put clear nail polish on him, and hardly any makeup. A little concealer to cover the dark circles under his eyes was all he had to wear.

His relief increased tenfold, when he was brought to the back room to get dressed. Instead of the frilly, fairy tale princess monstrosity he had been expecting, was a rather expensive looking white suit. It had a powder blue vest and tie along with it. It looked simple, elegant, and most importantly, comfortable.

"But... this is?" He turned to his mother, trying not to sound too hopeful. It could still be some kind of mix up.

"I know," she said with a pout, "it's so disappointing, isn't it?" Apparently the marriage contract said you had to wear a suit, and I didn't even check because I was just so excited. Your father knew, and he didn't bother to change it, because the groom's family provided it."

The bald omega had to suppress a grin. At least his new alpha seemed to have a decent sense of taste. Maybe things wouldn't be so bad.

Chapter Text

Genos arrived at the church for his wedding, dressed in a black suit, with a blue vest and tie, and trademark scowl fixed firmly in place. He had wanted to just have a simple legal ceremony at the courthouse, but Dr. Kuseno had insisted that they make a huge deal out of it. With only a week to get things ready, he had somehow managed to secure a venue, and invite friends, family, political connections, and business associates to attend. When the old man set his mind to something, it was almost frightening how much he could accomplish.

Most of the guests cautiously avoided speaking with him before the ceremony, warded off by his angry gaze, except of course Satoru. It seemed nothing could frighten him off until he had an opportunity to exchange pleasantries and offer his congratulations.

The surly blonde didn't exactly feel like congratulations were in order, condolences would probably be more appropriate. Once he was able to shake off his friend, he simply waited at the front of the church, by the podium. He wanted to get things over with, and yet somehow delay having to meet his new omega at the same time.

He must have been lost in thought, because before he realized it, everyone was in place, and the organist began playing a familiar tune, signaling the entrance of his "bride."

When he saw the Omega round the corner and begin the walk up the aisle, he couldn't believe his eyes. His jaw dropped, and his eyes opened wide in disbelief. There was no way, it just couldn't be.

In confusion he looked to his adoptive father, who was sitting in the front row. The old beta was grinning at him, sides shaking slightly as he held in a laugh at his boy's flabbergasted expression. It made sense now, why he hadn't pushed for Genos to meet the Omega before the wedding, he had wanted to keep it a surprise.

The Alpha's gaze returned to the Omega who was walking in time to the music, nearly to the front of the church. Looking much better in that sharp suit than he had in his costume, and seeming rather bored, was the bald man who had defeated Mosquito Girl the night before.

When the other man finally stood next to him, before the priest, he could hardly pay attention to the ceremony, it was like his brain couldn't quite process what was going on. He subtly scented the air, and sure enough, beneath a flowery perfume, was the scent of an Omega.

He said the words of his vows somewhat robotically, then watched as the other said his vows in a disinterested tone. They exchanged gold vows, and when prompted by the priest, they shared a quick chaste kiss on the lips.

Genos was surprised by the way his heart pounded when a pink blush spread across the Omega's cheeks. He wasn't usually interested in Omegas, but if it was this man, Saitama, then maybe being married wouldn't be so bad.

Chapter Text

After a long, dull ceremony that he had mostly tuned out, Saitama was directed to the reception area where they would be having dinner. It was there that he found himself seated next to the stranger that he had just vowed to spend his life with.

At least his new husband was attractive. With blonde hair, a good physique (as far as he could tell through the suit), and a handsome face, he looked like he could be a model. The pierced ears, black and gold eyes and the black skin of his hands, was an unusual look, but the bald Omega wasn't exactly up on the current trends.

He zoned out for a while, staring into space, pretending to pay attention as well-wishers stood up to make speeches or propose a toast. Most of them were strangers anyway. He was just looking forward to when the formalities were out of the way. He was getting tired of being stared at, and the perfume his mother had nearly drenched him in had made it so that all he could smell was flowers. It would be a relief when he eventually got the chance to wash it off.

It was a familiar voice that roused him from his daze. Mumen Rider, who was wearing something other than his cycling outfit for once, was making a toast. He really shouldn't have been surprised to see him there, that guy seemed to be friends with everyone after all.

Next to where Mumen was standing, dressing in a form fitting purple suit was his new boyfriend. What was that guy's name again? Something Panic? The guy was looking at Saitama with that face splitting grin of his. The Omega shrugged off the evil look coming from his self-proclaimed rival. He was kind of a weird dude.

They had fought quite a few times. The guy seemed to take offense to Saitama being faster than him for some reason, and would challenge him every chance they got. The Omega had been hoping that eventually Panic would have become strong enough to give him a decent fight.

He didn't want to get his hopes up. No one had been able to last more than a few minutes in the ring with him for a long time. Now that he was married, it probably didn't matter anyway. Without his husband's permission, he wouldn't be fighting again. An Alpha's protective instincts were usually extremely strong, especially once bonded. The idea of an Alpha being alright with the idea of their Omega fighting against other Alphas was almost laughable. It didn't matter how strong Saitama was.

The Omega grimaced at the thought of his boring new life, as a wealthy man's trophy husband. The most exciting thing he would be looking forward to would be brunch with stuffy business types, and maybe the occasional dinner party.

"When Saitama invited me to his wedding," the mention of his name brought the Omega's attention back to Mumen's speech, "I told him I couldn't attend, because another friend had already invited me to a last minute wedding to be held on the same day. It certainly is a pleasant surprise to find out I was able to see you both get married today after all. May you bring each other the joy you both deserve. I'm sure you'll be very happy together for a very long time." With that said, the Beta raised his glass for the toast, and they all took a drink.
After that the food was served. The dinner itself was alright, a three course meal with some rather expensive ingredients. Saitama mostly ignored, and avoided most of the polite conversation going on around him. It seemed his new husband wasn't much of a talker either. They ate next to each other, in a somewhat awkward silence.

After that, one of the largest cakes he had ever seen was brought in, and the two of them were directed to cut the cake together, while a photographer took pictures. Saitama felt his cheeks heat up, a blush spreading over his face when the Alpha's hand covered his, for them to hold the knife together.

He silently chastised himself for getting so flustered. He was going to be consummating the marriage that very night, this wasn't the time to be acting shy. That thought only served to make him feel more nervous. His heart started pounding so hard he worried the people around him could hear it. It wasn't that he didn't want to, it was just.... This guy was way out of his league. Someone that handsome could have had anyone he wanted. He probably had plenty of experience, with younger, hotter, Omegas. Omegas who had their hair, and curvy figures.

Saitama had never quite felt so much like an old, awkward, virgin in his life.

Chapter Text

Saitama's first impression of the reception that was held after the dinner, was that it resembled an awkward high school dance. Being married to his date only made it feel surreal. The Omega was relieved when he noticed that there was an open bar.

For a while he simply stood by the Alpha’s side while well-wishers, and business associates flocked around them to engage in pleasantries so boring he tuned it out almost immediately. He was fine with standing back and having his new Alpha do all the talking. For once, dynamic roles were working in his favor. The blonde hardly seemed thrilled to be talking to them himself. Though his words were strictly polite, and formal, he scowled at everyone that approached them.

After he had lingered by the blonde’s side long enough to be considered polite, Saitama detached himself from the group to go take a seat at the bar. He was in need of a stiff drink. He really just wanted to be left alone, but it wasn’t long before that Panic guy took a seat next to him.

“So you’ve been hiding your presentation this whole time,” the Beta started as he sat down.

“Eh, not really,” the Omega shrugged. “It’s not like you ever asked.” Saitama hadn’t exactly been going out of his way to tell everyone, it would be even harder to find a decent opponent if people had been taking it easy on him. Now that he had built up a reputation for being strong it didn’t matter if anyone knew anyway. It wasn’t like his popularity would take a dive, he was probably the least liked of any regular at the Fight-House.

“Well don’t think I’m going to let you keep being the strongest non-Alpha at the club. You’ve already messed with my title as the fastest there. I’m not going to just let you get away with retiring undefeated. You’ll just have to talk Genos Alpha into signing the permission form, so I can kick your ass,” the Beta said, that almost creepy grin of his spreading across his face the way it always did when he picked a fight.

Saitama simply shrugged in response. Frankly he would be ecstatic if his self-proclaimed rival became strong enough to beat him. Unfortunately, it wasn’t likely that he would get the chance to have boring fights anymore.

The long haired Beta must have noticed the hopeless look in Saitama’s eyes. He leaned in, voice lowered in a conspiratorial whisper. “The truth is, that heap of scrap metal over there,” he gestured in the general direction of the blonde Alpha, “can’t stand Omegas. He’s been bitching all week about it. I’ll bet he’ll let you fight as much as you want, just to get you out of his hair.” With that said, the Beta stood back up, and made his way toward the dance floor, disappearing into the crowd.

Despite the Beta’s adversarial tone, Saitama got the feeling that he had been trying to be helpful, in his own stand-offish way. He had been given the encouraging news that he would more than likely be able to fight again, and issued a challenge.

More importantly, he had been tipped off that his new Husband wasn’t into his presentation. He had known, of course, that the marriage was just for legal reasons. Still he was surprised by the pang of disappointment he felt at the news. It really was just his luck to end up with a husband that wasn’t interested. To him, it suddenly made sense why he had received such a high bid on the first day. They were in a hurry, and it didn’t matter what Omega he wound up with. They had probably just put a large bid on the least desirable one there, to guarantee the sale.

Still, his situation wasn’t nearly as bad as he had worried it would be that morning. He hadn’t exactly been expecting a romantic relationship anyway. They could probably get along well enough living like roommates.

Chapter Text

Genos could hardly contain his impatience. He was stuck exchanging pleasantries with the guests when he had barely been able to say a word to the fascinating man from the night before. He could hardly believe that they were married. He could barely convince himself that it was true. He desperately wanted to shout at all of them to screw off, so he could go get to know Saitama. He was just dying to ask him how he got so strong. He gazed longingly in the direction the Omega had gone, wishing he could have followed him. Unfortunately the crowd would keep following until he spoke with everyone.

He felt a wave of relief when he had finally managed to speak with all of them. He had managed to keep himself in check, and avoid the impulse to swear at all of them. Like it or not, it was important to keep in their good graces.

He was about to go look for his new husband, when he heard the voice of the last possible person that he wanted to deal with.

“Well I must say, you’ve certainly proved your point Genos.” The Blonde turned to Glower at Amai. His cousin was dressed in a flamboyant suit, the same colour blue as his own hair. The smug Alpa had a scantily clad female Omega hanging off his arm like an accessory. Her hair was bound in an elaborate updo, revealing a fresh looking bite-mark on the side of her pale neck. She was likely purchased just for the event, soon to be added to the harem, or sold off.

“What the hell do you want?” Genos asked abruptly. He had no patience left to be dealing with his cousin’s pompous attitude.

“Well I had come to celebrate your wedding,” his cousin started, “but now that I see the sorry excuse for an Omega you picked out, I can hardly consider this a happy occasion.”

Genos clenched his fists at his sides, suppressing the urge to punch that smug bastard right in his pretty face.

“I challenged you for your inheritance to push you into a proper marriage,after hearing about the indecent company you’ve been keeping.” The other Alpha gestured toward where Satoru was standing on the other side of the room. Whenever Genos thought Amai couldn’t possibly piss him off more, the asshole just had to prove him wrong. “I couldn’t have rumors about family members harming my reputation. Well you certainly showed me. Even if you did marry another Alpha, it would be better than that.”

The blonde Alpha had to swallow down a growl. All along his cousin hadn’t been in the least bit interested in Dr. Kuseno’s research. It had all been a scheme to force him into a marriage, just because of celebrity gossip bullshit.

Even more than being played, Genos was surprised to note that he was pissed off by how that blue-haired ass kept insulting his husband. How dare he? Saitama was amazing! He had to bite his tongue to keep from shouting and starting a scene.

“Tell you what, I’ll give you an easy out,” Amai continued, “as long as you haven’t mated him by morning, I’ll get my lawyer to have the marriage annulled, on the grounds of failure to consummate. I’ve prepared a settlement offer that would allow you to keep the lab, just in case you wound up with someone… unsuitable. If you don’t show up for the meeting tomorrow, I’ll just have to drag you to court instead.” The obnoxious Alpha handed him a card with the meeting details.

The week before, Genos would have jumped at any opportunity to get out of the marriage. Now, he refused to entertain the notion for even a second. It would be much too selfish. If he broke off their arrangement, what would become of Saitama? Omegas that didn’t fit into the mold of being traditionally attractive didn’t fare well in their society. He cringed at the thought of Saitama being used as a servant for manual labor, or bought by one of the “surrogacy” agencies that treated them like broodmares for producing as many strong Alphas as possible.

He would stay married to Saitama, to ensure that the man would be able to live as he pleased. He would make sure that no one would ever use the fact that he’s an Omega to subjugate him.

Knowing that it would displease his jackass of a cousin was just a bonus.

Chapter Text

By the time Genos had the chance to seek out his new husband, the reception was ending. The two of them had yet to have so much as have a conversation, and yet they were being herded to a vehicle, where a driver waited to bring them to a hotel room. The expensive looking black car had obnoxiously bright decorations attached to the back, with a sign that proclaimed “JUST MARRIED!!!!” The blonde Alpha couldn’t decide if the use of all caps was the most offensive thing about the sign, or if it was the fact that they had used comic sans for the font.

Saitama, however, seemed to have hardly spared the decorations a passing glance before getting settled into the back seat. Genos couldn’t help but to admire the Omega’s unruffled demeanor. The man had gone through the day’s life changing events with the bored expression of someone stuck in a waiting room before an unimportant meeting.

The Alpha had felt nearly desperate to speak to him all day, and yet, now that he finally had the opportunity, he found himself at a loss for words. The other man was gazing out the window, watching the scenery pass by with an unreadably black expression.

Genos took a deep breath to steady himself, and then instantly regretted it. He really should have specified that “no perfume” on the wedding preparation portion of the contract. In the confined space of the car, the flowery scent was far too potent. It was as if someone had dumped an entire bottle of the stuff on the poor man.

The driver either noticed the Alpha’s grimace of displeasure, or was having a difficult time dealing with the scent himself, because he wordlessly lowered all of the automatic windows a little bit. Genos made a mental note to make sure the man received a generous tip. The Omega kept his gaze fixed out the window, and muttered something under his breath about his “crazy over-enthusiastic mother.”

Genos could feel his heart hammering away inside his chest so hard that he was beginning to worry that the other man would be able to hear it. He took another deep breath to calm his nerves, grateful for the fresh air.

“Saitama,” he started, still unsure what exactly it was that he should say.

When the Omega turned to face him, those dark brown eyes meeting his own, he swore he felt his brain short-circuit. He blurted out the first thought that popped into his head. “I’d like to be your disciple.”

“Sure,” the other man replied before turning back to look out the window. After a few seconds he turned back to regard Genos with a puzzled expression. “Wait, what?”

Chapter Text

While Saitama had been hoping his new husband would allow him to continue fighting, he hadn’t been prepared for just how enthusiastic the young alpha was about it. After asking to become his disciple, the blond had explained that he had witnessed Saitama’s fight the night before. Apparently he had been so impressed by Saitama’s strength that he wanted to train under him. It was by a strange coincidence that the Omega just so happened to be married off to his only fan. Apparently luck was on his side for once. Not only would Genos allow him to keep fighting, he seemed excited by the prospect of watching him do it.

When they arrived at the hotel, Saitama was not surprised to see just how obscenely expensive it looked, not after how fancy the ceremony had been. The huge lobby even had a large fountain, with a sculpture of cherubs spitting water. As they got their keys and made their way to the elevator he found himself musing about how he could have been just as comfortable in a hotel less than a quarter of the price. He wondered if his husband was always in the habit of spending unnecessarily high amounts.

Their room turned out to be a penthouse suite that took up most of the top floor of the hotel. When they reached the door, the Alpha quickly moved to unlock it, then hesitated. The blonde was probably wondering if he was supposed to follow the tradition of carrying the Omega bride across the threshold. Saitama couldn’t help but feel that sticking to traditions like that would just be completely ridiculous for the two of them, considering the conversation they had on the way there. It would make about as much sense for them to do it the other way around.

With a slight smirk on his face, he walked up to the younger man, and scooped him up into his arms. It turned out that the Alpha was much heavier than he looked, but Saitama was still able to carry him across the threshold almost effortlessly. The Alpha’s expression of shock and awe was more than worth the effort.

“Sensei,” the blonde started to say, as he put his arms around Saitama’s neck for balance.

“Can you not call me Sensei?” Saitama cut him off. It was then that the Omega really became aware of just how close their faces were. His gaze drifted to the other man’s lips for a moment, and he found himself remembering the kiss they had shared at the wedding ceremony.

“Master then?” Genos asked. The Alpha sounded somewhat breathless, he probably wasn’t used to being casually manhandled like that.

Feeling a blush spreading across his face, Saitama set the Alpha back on his feet and closed the door behind him. “Don’t call your Omega strange things,” he chastised, “people will think we’re perverts.”

The hotel suite was pretty much just a fancy apartment. With a sitting area with a television, a full kitchen, and what was probably the largest the Omega had ever seen. There were some bags by the doorway, and he was pleased to see that his luggage was among them. He quickly went to his bags and looked for a change of clothes.

“I’m going to grab a shower,” he said as he searched through his bags for what he needed. “This perfume is driving me nuts.” When he came across his bottle of scent blocking soap he hesitated, remembering what that Panic guy had said earlier. “Want me to use this?” He asked, holding it up for the Alpha to see.

“No,” the Alpha replied quickly. “It’s fine. You don’t have to.”

With a shrug Saitama shoved the bottle of soap back in his bag, then went to go have his shower. The bathroom turned out to be quite large with a jacuzzi bathtub and separate, waterfall style shower. Saitama quickly stripped down and stepped into the stall, a sigh escaping him at just how good the hot water felt after a long day.

*****************************************

When Saitama had asked him if he should use the scent blocking soap, Genos realized that someone had told Saitama about his preferences. He couldn’t think of any other reason for an Omega to ask that on their wedding night. The blonde Alpha had quickly told him he didn’t need to bother. He didn’t want the other man to have to hide a part of himself, just to make Genos more comfortable.

He had never been particularly interested in an Omega’s scent before, but he had never met an Omega that could easily pick him up as if he weighed no more than a feather before either. That had been… exhilarating was the only word that came to mind. With the metal that was used in his prosthetic limbs, as well as much of his skeletal structure in his torso, he weighed about two hundred pounds more than someone his size usually would. Just thinking about it made his heart flutter in his chest. It didn’t matter what Saitama smelled like, that amazing strength, and the gentle way he had been held, was probably the hottest thing Genos had ever experienced.

While the other man showered, Genos sat on the sofa, and tried to concentrate on watching something on the large flat screen television. He tried in vain to keep his mind away from the topic of the Omega’s naked body, wet and covered in soap.

He let out a small groan of frustration with himself. He just couldn’t seem to stop thinking about it. He had been worried that he wouldn’t be attracted to his new husband, but it would seem his problem was just the opposite. When he decided that he was going to make sure that Saitama was not taken advantage of by any Alpha, that included himself. It didn’t matter how much he wanted it, he decided that he would not make a move unless Saitama was the one to initiate. Unfortunately, he didn’t think that would ever happen, he couldn’t imagine someone actually being interested in someone with a damaged, scarred, and mostly mechanical body like his.

After about fifteen minutes, Saitama returned, wearing a pair of striped pajama bottoms, but no shirt. Genos had to fight down the urge to touch, kiss, and lick every inch of the smooth skin that was on display.

“So… uh,” the Omega gestured in the direction of the bed, and then gave Genos a questioning look. Not quite trusting himself to say anything right at the moment, the Alpha gave a slight shake of his head, and gestured for Saitama to join him on the large sofa instead.

Even though they were supposed to consummate the marriage, it wasn’t like Amai’s lawyers could prove if they had sex. “We don’t have to do that, as long as we’re bonded it should suffice.”

“Okay.” The other man replied simply, then removed his shirt and tilted his head to the side to grant Genos easy access to his neck. The Alpha’s eyes widened and he had to suppress a startled noise at the sight. Saitama had appeared to have an average build with his clothes on, but underneath he was certainly well-built. The blonde had to force himself to keep his eyes on the Omega’s face, and not his toned abs.

Mating bites were usually given during sex, because the hormones during climax would prevent the Omega from experiencing any pain. Saitama didn’t seem to have any concern about doing things the painful way.

“Wait,” the alpha said, beginning to unbutton his shirt, “I want you to bite me too.”

The Omega looked at him with an unreadable expression. “You sure about that?”

“I’m sure.” Genos replied, as he finished unbuttoning his shirt. He hesitated a moment, taking a deep breath to steady his shaking hands, before removing his own shirt as well. “If you’re ok with it after seeing this...” He wanted to give Saitama the choice. He wanted to let the other man see the scars around where his prosthetic arms connected to his shoulders, and the network of burn and surgical scars that covered most of his torso. He wanted to make sure the other man had the opportunity to reject him.

The Alpha closed his eyes and braced himself for a reaction of shock and disgust, but it never came. Insead he felt a hand trace along the scarred flesh of his shoulder and down his arm. When he opened his eyes the other man was right in front of his face.

“Can you feel that?” The Omega asked him. Genos nodded, taken off guard by how the gentle touch had sent a bolt of arousal through his body. When the other man nuzzled against the side of his neck he couldn’t help but to let out a soft gasp.

“Are you ready?” Saitama asked him. The feel of the warm breath against his skin sent pleasant shivers up his spine. He adjusted his position, so that he was lined up with the Omega’s neck as well, and nodded. He felt the jolt of pain shoot through him, at the same time he tasted coppery blood in his mouth, and the bond was sealed.

Chapter Text

It was when the blonde Alpha removed his shirt that Saitama clued in that the striking black and gold of his eyes, and the black skin of his hands, were not merely a fashion statement, and how he managed to be so much heavier than he looked. It seemed like the arms were high end prosthetics, attached to the scarred shoulders. Now that he thought about it, he vaguely remembered something about a lab and designing prosthetics was written in the information they had given him before the wedding.

Although Genos’ face and neck were completely free of marks, the rest of the revealed skin was covered in a network of scars. Most appeared to be from burns, criss crossed by straight lines that were probably surgical. It was obvious that he had been through a lot. Despite the scars, or perhaps, in a way, because of them, Saitama couldn’t help but to think the Alpha looked beautiful.

Genos was facing away, eyes shut tight, apparently expecting a bad reaction. Saitama could almost feel his heart drop. This Alpha was offering the freedom he thought would be taken from him the moment he was married. Did he really think that Saitama would turn that down, and refuse to bond with him over something so shallow? It if weren’t for the fact that he thought the younger man wouldn’t be interested, the Omega would have offered to take things to the bed, and show him just how desirable he was.

Instead, Saitama reached over, and gently ran a hand from the Alpha’s shoulder, down the synthetic skin of his arm. “Can you feel that?” He asked. The blonde looked at him with a shocked expression, then nodded. He was glad to know that Genos didn’t have to live without feeling in his arms, high end prosthetics indeed. Saitama moved closer, so his face was lined up with the Alpha’s neck, and nuzzled him briefly to offer some comfort. “Are you ready?” he asked.

When he felt the other man nod, he bit down. He felt a sharp pain in the side of his neck, as he was bitten as well. It was intense, but not unbearable. He had received worse injuries back when he had first started fighting. It was then that he felt the bond form, as if a puzzle piece he hadn’t realized was missing clicked into place in his mind.

Suddenly, he was aware of the other man in a way he hadn’t been before. It was difficult to explain, even to himself, but he knew, from then on he would always know when Genos needed his help. As he released his bite, the Omega felt a sense of satisfaction. From then on he would be able to protect that man, his husband, his mate. He would make sure that he would never again have to suffer like he had in the past. He understood how much of a sacrifice the Alpha was making in order to give Saitama his freedom, protecting him was the least he could do.

When the Alpha released his bite on Saitama’s shoulder, he immediately began to lick the wound. The Omega had to suppress the urge to moan in response. Each lap of the other man’s hot tongue sent a wave of pleasure through him. He was sure that Genos was only doing it to stop the bleeding (both Alphas and Omegas had an enzyme in their saliva that disinfects and stops bleeding), so he pushed down his feelings of arousal. He returned the favor, lapping at the mark that he had left, until he was sure the bleeding had stopped.

A wave of exhaustion swept over him, and he found himself suddenly on the brink of falling asleep. Drowsiness was a common side effect right after a bond was formed. It would seem that Genos had been affected as well, when he had finished tending to Saitama’s mark, he had stayed put, resting his head on the Omega’s shoulder. The blonde’s slow, steady breathing indicated that he had already fallen asleep.

Saitama smiled at him fondly, and then carefully gathered the Alpha in his arms to carry him over to the bed. Genos didn’t stir at all as the Omega moved him and tucked him in under the blankets.

Once he was sure that the Alpha was taken care of, Saitama could no longer fight off his exhaustion, not even long enough to cross the room again to go sleep on the sofa. He collapsed into bed alongside the other man. Given that they had just bonded, he figured the Alpha wouldn’t mind all that much if they shared the bed, just this once.

Chapter Text

Genos couldn’t remember the last time he had slept so well, so when he first started to regain consciousness, all he really wanted was to fall asleep again. When was the last time he had made it through a night without being tormented by nightmares?

He stubbornly kept his eyes shut, and snuggled closer to his pillow. It was a rather strange-feeling body pillow, now that he thought about it. It was kind of hard… and it was breathing. Memories from the day before rushed back to him, and he felt suddenly very awake.

The “pillow” that he had been sleeping on turned out to be Saitama’s shoulder. They were both in the bed, though the Alpha had no memory of moving from the couch. The Omega was sleeping on his back, and Genos was curled up against his side, one of his arms draped across the other man’s muscled stomach.

The realization that Saitama must have carried him to the bed dawned on him, and the Alpha wished that he had been awake enough to remember it. He couldn’t bring himself to be too disappointed though, given that he was able to wake up next to him like that. He assumed that the Omega had also passed out from exhaustion after the bond was formed, and was grateful that things had worked out that way. He wasn’t sure if he would get to have a morning like that again.

He checked the other man’s breathing, making sure he was still asleep, before shifting up a bit, so that he could sniff his neck. Genos was surprised to find that the scent of Omega didn’t bother him at all, in fact, he thought Saitama smelled amazing. Instead of the flowery scent that he usually associated with Omegas, he smelled like a forest, just after the rain. The Alpha briefly wondered if that was just because they were bonded, then decided that he didn’t care.

He had been attracted to Saitama from the first time he laid eyes on him, but those feelings were quickly developing into something deeper. He was already hopelessly falling for him. Unfortunately his feelings only served to complicate things. There was no way someone like Saitama could be attracted to someone with a body like his.

After that sobering thought, he decided it would probably be best for him to get up. He suddenly felt too exposed without his shirt. The Alpha moved carefully, so as not to wake the other man, as he got out of bed. Once he was up he found a change of clothes from his luggage. He made his way over to the bathroom to shower and get ready, stopping in the doorway just to take another look at his new mate.

Just the thought that the two of them had slept together shirtless, bare chests against each other had him feeling a little light headed. He was definitely in need of a cold shower that morning.

**********************************************************

After showering, and getting dressed in a long sleeved shirt over a pair of black jeans, he called for room service to bring breakfast. He would have to go deal with Amai and his lawyer as soon as possible, to get it out of the way, and he didn’t want to have to do it on an empty stomach.

He waited quietly until the food arrived, checking his phone for messages. He responded to a few, but decided to ignore the rest until later. When the food arrived, he took it over to the sitting area, setting it on the coffee table in front of the sofa, before waking the sleeping Omega.

It would seem that having the food ready first had been a good call. Saitama had initially reluctant to get up, if not outright grumpy, until he smelled the food. Genos made a mental note to get up before the other man and get breakfast prepared first from then on. It would help make their mornings together more pleasant.

After giving the Omega some time to eat and have some coffee, the Alpha finally worked up the nerve to ask a question that had been on his mind since he had first laid eyes on him. “Is there any particular reason that you shave your head?”

“I don’t shave it,” the other man replied, “it’s just how I am.”

“But that would mean you’ve gone bald at such a young age.” Genos cringed internally almost immediately after blurting out his reply, his lack of tact was going to get him into trouble.

“So what if I’m bald?” Saitama snapped back, his tone defensive.

“It isn’t that there’s anything wrong with it,” the Alpha replied, “I think you look handsome, I don’t really like long hair on men anyway. It’s just… I didn’t know if it had something to do with your training.”

The Omega’s expression softened. “Nah it’s nothing like that. It’s just from the suppressants.”

Genos felt his stomach clench with anxiety. Hair loss was a possible side effect of long term suppressant use, but it was almost unheard of. Taking suppressants for too long could result in severe health complications, such as damage to vital organs. “How long were you taking them?”

“Hmmm… well my first heat had to be stopped with emergency suppressants after I kicked down my bedroom door and put my dad through a wall, for getting in my way. I gave him a black eye, a concussion, and broke two of his ribs. My mom had to sneak up from behind and scruff me in order to get me with an emergency suppressant injector. After that my doctor decided it would probably be best to keep me on suppressants until I got a bonded mate, so…”

Genos was completely shocked. If he had been on them from his first heat, that would mean Saitama had been taking the dangerous medication for at least a decade. Was his doctor insane? Did his parents not care about his health?

“You don’t have to worry about it though, apparently some Omegas have an instinct to seek out a mate rather than just waiting for one to come to them, and my dad tried to keep me from leaving, but I didn’t exactly get along with him at the best of times. Now that I’m bonded it shouldn’t happen again, and I would never do that to you I swear.”

Genos stood up and moved so that he was standing in front of the other man, then reached out and tilted the other man’s chin up so that he was facing the light. His sclera were white, that was good, no signs of jaundice. He crouched down and pressed an ear to the other man’s chest, instructing him to take a deep breath. Saitama seemed a bit perplexed, but complied anyway. Heartbeat and breathing sounded alright. The Alpha then placed his hands over where the Omega’s kidneys would be, and pressed firmly. “Does that hurt at all?”

“N-no,” Saitama replied, “I’m fine, really. I’ve been checked by my doctor a hundred times.” Genos looked back up at the other man, he was in remarkably good health considering he had been more or less taking poison for a decade. He did look a bit flushed though, so the Alpha couldn’t entirely stamp out his concern. He made a mental note to discuss the situation with Dr. Kuseno as soon as possible, then went back to his spot on the sofa.

Once they finished eating, Genos explained that he had some business to attend to but that he would return as quickly as possible. He didn’t want Saitama to have to deal with the annoyance of a meeting with his obnoxious cousin. The still healing bite mark on the Alpha’s neck should be all the evidence required.

Before he left, Genos dug through his luggage to find a pair of gloves and his sunglasses, to wear.

“Do you normally wear those when you go out?” Saitama asked as he was slipping them on. Genos simply nodded in return. “Huh, that’s too bad, you look a lot cooler without them.” Before the Alpha could think of how to respond, Saitama turned on the tv and started flicking through the channels.

Chapter Text

Genos stormed down the city sidewalks, his expression dark, and the scent of agitated Alpha surrounding him like a thundercloud. Usually he would have preferred to drive himself, but he felt the need to let off some steam before the meeting. With every step he took away from his new mate, he felt a little more unstable. His instincts screamed at him to turn around and go back to protect his Omega, but he pushed forward anyway, reminding himself that the other man was not in need of his protection.

He had considered taking a taxi, but knew that with his heightened irritability and the intensity of his pheromones, it would have been very unpleasant for anyone unlucky enough to drive him.

When he reached the building where his cousin, and his lawyer were waiting, the receptionist could hardly raise her eyes to look at him. Her voice quivered as she gave him the direction to the office where the meeting was to take place.

As he made his way to the office, the well-dressed lawyers, and clients alike, scrambled to get out of his way. Even Alphas quickly ducked into the nearest room to avoid crossing his path. They had no interest in being noticed by this alpha with furious body language, and dangerous scent.

When he reached his destination he shoved the door open without bothering to knock. Inside, his cousin, and a male Beta in a suit, abruptly cut off their conversation.

“Ah there you are,” Amai greeted him with a slick, insincere grin. “I see you’ve come to take me up on my offer.”

Genos wanted to tell that creep to piss off, and go take care of his own newly bonded omega, but managed to hold himself in check by a thread. He took a deep breath, and managed to bring his fury down to a simmer.

“I’m here to tell you to take your offer and shove it,” he replied. Given the circumstances, it was about as polite as he was going to get. As he crossed the room to join the others by the desk, he pulled down the collar of his shirt to reveal the bite mark Saitama had left the night before.

For a moment, Amai was silent, first confusion and then anger spread across his face. “Why in the hell would you do that?” Slamming a fist down on the table before him he snarled “just because you’re adopted doesn’t mean your actions won’t affect our families reputation.”

“Well that’s it then,” the lawyer cut in. “There’s no legal grounds to annul the marriage now, and you no longer have a claim on the inheritance.” He scented the air, and almost visibly shuddered. “I believe it would be best to wrap things up, it wouldn’t be wise to keep him any longer than necessary.”

Genos was about to turn around and leave, but Amai didn’t seem to have the sense to let it end there. “It’s a shame,” he said, “to have a thing like that connected to my family’s image. I guess I won’t be able to get rid of it… Unless of course something were to happen to him…”

He didn’t even have an opportunity to finish the thinly veiled threat before Genos shoved the table that was between them aside, and grabbed him by the collar, slamming him back against the wall. The outraged Alpha pulled back, and landed a heavy blow across his cousin’s face, before throwing him to the ground.

“You saw that right!” Amai shouted, a red welt already appearing on the face he was seemingly so obsessed with. “I want to sue this maniac for everything he’s got!”

The lawyer pinched the bridge of his nose, his frustration and desire to end things quickly were starting to outweigh his dedication to professionalism. “Unfortunately, a case like that would be thrown out of court. Given how a new bond disrupts the hormones, and how your comment could be perceived as a threat to his omega, he won’t be held liable.” The beta started walking toward the door, “I’m leaving before anything else happens, I suggest you do the same.”

Genos glared at the other alpha, growling just under his breath, just daring him to say something. It would seem that common sense finally caught up with him, as the blue haired man scurried out of the room like a whipped dog.

The blond waited until the hallway would be clear before leaving the room himself. He wasn’t exactly interested in dealing with the aftermath if he beat the pain-in-the-ass to death. He would take his victory, and return to his waiting omega.

As he rushed back along the city sidewalks, Genos could feel the tension leave him. It just felt right to be running toward his mate. They hadn’t even been together for a day, and already he couldn’t stand being without him.

Chapter Text

After the Alpha had left, Saitama tried to pay attention to the TV for as long as he could. He switched it to the news, but found it difficult to pay attention for long. A segment about fires in the commercial district piqued his interest for a moment, but his mind wandered again once he confirmed that they hadn’t affected any of the places he frequented.

He felt a bit uncomfortable being separated from Genos so soon after bonding, but he didn’t want to fuss about it too much. He could tell by how tense the other man was that something was bothering him, and he didn’t want to add to it.

When he felt a flash of distress though the bond, rage apparently, he moved to the bed because he could no longer focus on the TV, he hadn’t particularly been interested in the story about local arson incidents anyway. If it had been fear, or pain, coming from his mate, he would have gone to him. It was still all too tempting to rush out of that hotel and throttle whoever had enraged his mate, but the Alpha probably wouldn’t appreciate having some crazed Omega stirring up trouble. Instead it would be better to just relax and wait for Genos to return.

As he tried to relax, he let his mind wander to the previous night. A flush spread across his face as he thought about how they had shared a bed. It had felt so natural, and so very good, to hold the blonde man to his chest as he had drifted off to sleep. He couldn’t help but wish that they had done more than just snuggle.

He shook his head, as if to clear away thoughts that were starting to edge on being erotic. It wouldn’t do him any good to dwell on it. His attraction to his new husband was already intense enough without him obsessing over it. He would only end up driving himself crazy if he couldn’t let it go. There was no way the other man could return his feelings. He just wasn’t the Alpha’s type.

Even though he didn’t want to think about it too much, his mind kept wandering back to what it would have been like if they had actually consummated their marriage. Would Genos have been rough with him? Or maybe it could be the other way around, with him pinning the other man to the bed, while he bit, teased, and explored his body, to see what kind of sounds he could get out of him.

He stared at the ceiling, and tried to think about something else. His fantasies were going to have to stay that way, because it looked like outside of his heats, the Alpha wouldn’t be interested in him that way at all.

Chapter Text

Genos felt relief wash over him the moment he stepped into the hotel suite. The scent of his new mate was just barely perceptible, but enough to calm his raging instincts nonetheless. The respite was brief however, because when the Omega walked out of the bathroom wearing sweatpants, but no shirt, driving his instincts crazy in an entirely different way.

It was almost unfair, being married to someone with perfect pecs, and not being able to touch them. Even more unfair, was getting a good look at those sculpted abs. Genos quickly turned away, looking at the TV without really watching it, to hide the blush he could feel spreading across his cheeks.

“Hey,” Saitama greeted him, “did you have anything planned for today?”

Originally, the Alpha had intended to just go back to work the day after the wedding. He didn’t expect to have any interest in spending a honeymoon with his new mate. He was grateful that Dr. Kuseno had insisted that he take a week off. Still, he had only booked the hotel for one night, and hadn’t made any plans for what to do after they checked out.

“Nothing in particular,” the Alpha replied, while mentally scrolling through a list of different places they could go. He almost regretted his obsession with his work, when he realized he hadn’t really gone to any of the local restaurants, and didn’t know much about any of the local attractions.

The Omega dug through his bags for a moment, before pulling out a couple of t-shirts, and another pair of sweatpants. “Perfect,” he said, “Let’s hit the gym.” The Alpha must have let his surprise show on his face because the other man quickly added. “You asked me to be your trainer right? I don’t really know how much I can teach you, but we might as well work out together. I haven’t been able to go to the gym since before I was dropped off at the auction house so…”

The blonde hastily agreed. Of course Saitama would have wanted to do something casual and practical. He felt a bit foolish for even considering lavish, romantic date ideas. The idea of working out together was far from disappointing. He was more than a little excited to learn the other man’s workout routine. Did he have any special techniques? Did he have a specialized diet? Was there a certain protein shake that he drank after exerting himself?

He gratefully changed into the gym clothes the Omega lent to him. He hadn’t even considered something like that when he had packed his bags. It would seem his married life was going to be full of surprises.

Chapter Text

After getting into the borrowed gym clothes, Genos had offered to call a cab. Saitama quickly dismissed the idea. “Why waste money on something like that? It’s nice enough to walk, and then we’ll already be warmed up when we arrive.”

Genos was quick to agree. Was walking everywhere part of how the other man kept in shape? Was this going to be a part of his training? He almost considered taking notes.

“So,” the Omega snapped him out of that train of thought, while heading out the door to the room, “how often do you work out?”

“I go for a run every day,” The Alpha replied. He made sure to do lots of cardio, but didn’t usually do any activity outside of that. He didn’t see the point in lifting weights. He was constantly working to improve his strength by upgrading his prosthetics.

“Hmmm… ok so I’ll just have you do the same exercises as me from now on. Those limbs of yours are pretty heavy, you’ll probably move around better if we work on the muscle you do have.

The Alpha thought again about the fight he’d lost the night before the wedding. His movements had indeed been slow and clumsy compared to the other fighter. It had taken almost no effort for her to grab onto him and shake him like a rag-doll. It would seem that he did indeed need to focus on the organic parts as well.

As they made their way down the hall toward the elevator, he asked, “What is your workout routine? Do you do any special exercises? Do you take any special supplements?”

“Not really, I do calisthenics, lift some weights, and cardio.”

The other man’s reply only added to his confusion. “That’s just basic training,” the alpha replied, “surely there’s something more to it?”

Saitama shrugged. “I don’t know what else to tell you man. I work out every day, eat protein, and I fight as much as I can. That’s really it.”

As they rode the elevator to the ground floor in silence, the blonde processed the new information. It would seem that the other man didn’t get to be a champion because of his exercise routine, or supplements. It seemed that even he wasn’t particularly sure why exactly he came to be that way. If it wasn’t from exercise alone, perhaps it was because of how often he fought. “Spar with me!” The Alpha blurted.

The Omega looked at him as if he’d lost his mind,“no way, not gonna happen.”
***

Genos spent the thirty minute walk to the gym convincing his new mate to spar with him. “If I hit you I might break your parts, or your face,” the Omega had countered, as he strode quickly along the sidewalk. He didn’t know how much those prosthetics cost, but it was probably way too much to go damaging them for the hell of it.

It wasn’t just that the idea of breaking expensive technology bothered him. He didn’t think he could bring himself to hit the blonde, even if he avoided the prosthetics.

It must be his face he thought, it’s too handsome. It would be too much of a shame to leave a mark on someone like him. He looked away, to hide the blush he could feel spread across his cheeks at the thought.

He’d never felt hesitant to fight someone before, it was the Alpha’s fault. With his being so kind, and respectful, and his stupid handsome face, he was just completely unhittable. In fact, the Omega was going to have a very difficult time watching him spar with anyone at all. He would have to work on keeping his protectiveness from getting out of hand. Genos wasn’t going to prevent him from fighting, he had to at least give him the same freedom.

“Please, I need you to spar with me if you're going to train me to be a better fighter.” The Alpha pleaded with an expression that, even behind the sunglasses, reminded Saitama all too much of a kicked puppy.

“Fine,” the bald man replied with a sigh. The eager smile that lit up the Alpha’s face was certainly worth going along with what he wanted. As long as he was careful, it might actually be fun.

***

As they passed the front desk at the gym Genos reached for his wallet, fully expecting to have to sign up, or at least pay for the day. “It’s cool,” Saitama said, as he pulled a card from his pocket, “I’ve got the platinum membership, so I can get guests in. It’s kinda pricey, but don’t worry about it, I arranged it with Fubuki so it comes off my prize money.”

Something about the comment seemed a bit odd to the Alpha, why not just have the payments deducted automatically from his bank account? The signs around the gym said that it was open to all genders and presentations, so he didn’t need to hide his status by going through a company membership.

As soon as they started their workout, it was all but forgotten. As he had said before, Saitama took him through a series of simple compound exercises. It was, more or less, an average strength training routine. What set it apart, at least in the Omega’s case, was the obscene amount of weight he did it with. The bald man seemed to barely bat an eyelash, while lifting hundreds of pounds.

On the other hand, he insisted that the Alpha start out with hardly any weight at all. “It’s more important to work on your form first,” he said when Genos tried to convince him he could handle more, “if you don’t you could really hurt yourself when you move up to higher weights.” It was hard to argue with that logic.

In fact it became hard for him to think of much to say at all, when the other man had to touch him to help adjust his position. Just having him stand so close, and the occasional feeling of the Omega’s hand adjusting his posture, was filling his mind with all kinds of suggestive thoughts.

When a hand lingered on his arm for maybe a few seconds longer than he expected, or their eyes met and he felt overly conscious of how close they were to each other, he could swear he felt sexual tension, like crackling electricity, in the air between them. He tried to ignore the feeling as much as he could. An Alpha’s instinct often led them to think Omega’s were interested in them, when they were just being nice. The new bond hormones probably only made it worse.

He thought about just asking the Omega how he felt. A few times he tried to ask, but found himself somehow unable to form the words. He told himself it was because he didn’t want to pressure someone he only met the day before, but knew it was just as likely that he feed the answer would be disappointing. The way the other man treated him was nearly enough to make him forget, at least for a moment, how horribly unattractive he felt.

He was quickly distracted from that brooding line of thought, when Saitama led him to the squat racks. In fact, as the Omega demonstrated the proper technique, it was very difficult for him to think about anything at all.

Chapter Text

After they were finished with the weights, Saitama led the blonde to an open area of the gym. There were mats stacked by a corner of the room that could be set up wherever they were needed. A few were already in use. A couple of Alphas were sparring on the far side of the room, and a handful of others were either practicing different moves, or doing yoga.

Once he managed to focus on something other than trying not to ogle his mate, Genos had begun to appreciate the atmosphere at the gym. He had always assumed he would be self-conscious at a place like that, but he was actually quite comfortable there. Though there were quite a few people around, it wasn’t crowded. More importantly, it seemed that everyone was minding their own business, too focused on their own workouts to stare at his unusual features.

Once they set down a mat, out of the way of the others, they got into position opposite each other. “Alright… let’s just do this, I guess,” the Omega said with a shrug. He hadn’t even taken a fighting stance, but simply stood casually with his arms at his sides, waiting for the Alpha to make the first move.

The Alpha got into a ready stance, arms up, knees bent, and took a deep breath to steady himself. “Please make surw you go all out,” he requested, before he swiftly closed the distance between them and began a series of punches.

The other man skillfully dodged or deflected his fists each time. He should have known that such a straightforward attack wouldn’t work against such an experienced fighter. He would need to switch it up. He feigned with his left hand, and as the bald man dodged, he kicked high with his right leg.

If it had worked as intended it would have knocked the other man back, giving him an opportunity to land a couple punches, instead he was thrown off balance as he leg was grabbed and lifted higher. He struggled to stay upright for a moment, only to have a swift kick to the back of his other knee take him down. He landed on his backside with a soft thump, and braced himself for a counter attack.

Instead of pressing his advantage, the other man held out a hand to help him up. The Alpha scowled, but accepted the help without thinking. “How will I be able to judge the difference in our abilities if you go easy on me?”

The Omega shrugged, “I’m not going to hit you,” he replied, “sparring like this is probably fine.”

The blonde launched into another round of swift punch, channeling his annoyance at being taken lightly into each attack. Sure, the one time Saitama had witnessed him fighting had been a disaster, but he was actually quite strong, even for an Alpha. Even though he was lacking in training and experience, his raw talent and natural instinct had easily carried him through fights in the past.

His second volley of attacks was suddenly cut short when his opponent somehow managed to deflect his attack and grab onto his arm. Before he could react, the Omega used his momentum to throw him to the ground. He rolled immediately, dodging an attack that didn’t come. Again, Saitama was holding out a hand to help him up.

The Alpha was equal parts frustrated, and impressed, as he launched another volley of attacks. This time using elbows and knees as well, to try to find an opening. When his feet were kicked out from under him, he rolled and bounced back up. He advanced again, with another barrage of punches, before the other man could hold his hand out again.

“We have a two way bond,” the alpha growled, “there isn’t any reason you shouldn’t be able to fight back. Fight me seriously!”

His frustration must have made him sloppy, because the Omega was instantly able to kick his feet out from under him, slamming him down onto his back hard enough to momentarily take his breath away. This time, Saitama didn’t just say standing, but moved with him to the ground, landing between the Alpha’s knees, one hand pinning his chest to the ground with alarming strength. He didn’t even have a moment to process what was going on, before he saw his opponent’s free hand was headed for his face at a terrifying speed, the Alpha’s instincts screamed “danger”.

When that fist veered off course at the last moment, slamming to the mat with a startlingly loud bang, Genos was filled with relief that it hadn’t made contact. His heart was pounding in his chest, and he was panting to catch his breath. He was suddenly all too aware of the other man’s body against his own. Their faces were so close he could feel the other man’s breath against his cheek.

The way his mate had so completely overpowered him, had gone from frustrating, to horrifying, to arousing, so quickly it felt like he was going to get some kind of emotional whiplash. Think unsexy thoughts! Think unsexy thoughts! He told himself. There would be no hiding it if he were to get aroused with the other man close enough to notice any change in his scent, not to mention how obvious it would be if he got an erection.

He wasn’t sure if he was grateful or disappointed when the Omega stood up, and again helped him to his feet. “I think that’s enough for now,” he said as he started to walk toward the doorway, “Let’s go get lunch. I’ll grab our stuff while you put the mats away.”

As the other man walked away, Genos became aware of the sudden silence in the gym. The sound of the Omega’s fist slamming into the mat had been loud enough to startle the others into momentarily pausing their own workouts. As he wiped down the mat, they seemed to realize that there wasn’t anything to be concerned about, and went back to minding their own business.

When he lifted the mat he noticed what appeared to be a dent with cracks spreading out from it like a spiderweb, on the floor beneath. Had that been there before? It probably was… it must have been, but still, he didn’t think he was ready for Saitama to fight him seriously after all.

Chapter Text

They returned briefly to the hotel to take turns showering, and gather their things. This time, as they had their luggage to bring with them, Genos was able to convince Saitama to let him call for a rental car. The drug-like effect of being newly bonded seemed to have mostly faded, or perhaps it wasn’t a problem because they were together.

They sat in the hotel lobby in comfortable silence, sipping on complimentary coffee while they waited. It wasn’t long before the concierge came to inform them that the vehicle had arrived.

After they packed their things into the trunk, the Alpha held out the keys to his mate. “Do you want to drive?”

“Can’t,” his new mate replied with a shrug, “I don’t have a license.”

The blonde couldn’t hide his surprise at the response. Why on earth would a grown man not bother to get his license in a city with such a dumpster fire of a public transportation system? Even if the other man preferred to walk it hardly seemed like a decent excuse not to get something so basic. Getting a license was generally considered a given, a milestone on the road to adulthood.

“Dad said that it would end up costing too much for insurance and gas if I started driving,” the Omega explained, “so I couldn’t get my parents to sign off on it.” He said it as dispassionately as if he had been commenting on the weather, rather than describing how he had missed out on something an Alpha or even a Beta would consider an essential part of growing up

When he got in the car, the other man was already settled in, looking out the window with an unreadably neutral expression. Unsure of how to respond to that, he just asked, “where do you want to go?”

“The Fight-House would be open for lunch now,” the bald man replied, “we might as well go there.”

***

When they arrived at the Fight-House, the first thing Genos noticed was just how different the atmosphere was during the day. What at nighttime would have been the dancefloor, had been transformed into a brightly lit dining area. There were families, and groups of teenagers scattered about, seated at the small tables. Some were focused on their meals, while others watched the fight with mild interest. In the ring a couple of young Alphas, who couldn’t have been any older than fifteen, engaged in a rather uncoordinated scuffle. There wasn’t any gambling, and they didn’t appear to be serving alcohol either. It was a bit impressive, how they had turned a club with a somewhat questionable reputation into what felt more like a casual family restaurant.

“I didn’t realize this place was open to younger fighters,” the blonde commented as Saitama led him to take a seat at a small table near the back.

“If there’s a way to squeeze some extra income out of a business, Fubuki will find it,” the bald man replied as he took his seat. “I’m lucky she did, when I was that age, this place pretty much saved me.”

Before the Alpha had the chance to ask what he meant, their server, a short female Beta came up to them. The Omega exchanged a greeting and some casual small talk with her, before placing an order for the two of them, and telling her to put it on his tab before Genos could offer to pay.

“We should see if we can talk to Fubuki while we’re here,” the Omega said as she walked away, “she’ll need your bank information to transfer the prize money.”

“I think it will be a while before I win any fights,” the blonde replied. The memory of his crushing defeat the last time he was at the Fight-House was all too fresh.

“Oh, yeah that too, I guess,” came the reply. “I meant they need it for my winnings though, I don’t have a bank account.”

He almost asked if Saitama’s parents just gave it to him in cash, or just bought things for him with the money. After reflecting on what he had learned about the Omega’s family so far, he realized that it was worse than that, his father probably just pocketed anything he earned. He had heard before that an Omega’s money technically belonged to whoever had custody of them, but until now he hadn’t really believed that there were adults being denied access to their own income.

“We’ll stop at my bank and fix that on our way home,” he replied. The idea of having the other man’s winnings paid through his account made him feel sick to his stomach. “You’ll just have to give them the details next time.”

“Sure,” the Omega responded casually, before turning to watch the TV that hung on the wall next to the bar. On the screen a concerned looking reporter stood in front of what appeared to be the remains of a burned building. Though his response seemed casual, nearly indifferent, Genos thought he could see the trace of a smile on his new partner’s face.

As they waited for their food, the Alpha’s mind kept going back to how Omegas were treated. They couldn’t live on their own, someone always had to have custody of them as if they were children. They couldn’t get a job, drive, have money, or even see a doctor without their guardian signing off on it. They were bought and sold, the price called a “dowry” to make it more palatable for the masses.

As an Alpha, he had never been treated like that. He hadn’t really interacted with Omegas before, so he had always just believed it when he was told that they were happy to be taken care of. He had believed that they were delicate little flowers who only thought about pretty things and domestic life. He was starting to suspect he had believed a crock of shit. “What’s it like?” He blurted out the question, then inwardly cursed his awkwardness.

“What’s what like?” The other man turned back to him with a confused expression.

“What is it like to be an Omega?”

***

Saitama leaned back in his chair and looked at the ceiling while he mulled it over for a moment before answering. He wasn’t entirely sure he was really qualified to answer something like that. He wasn’t much like other Omegas that he had met, but it wasn’t like he was not one of them.

It hadn’t been a part of how he was raised. There were hardly any Alphas or Omegas in their family, so his parents hadn’t bothered to do the genetic testing. His mother thought it would be more fun if it was a surprise, and his father was just happy to save money. He had been raised like a male Beta. It had been nice, no pressure to be a certain way. He’d played sports, made friends, gone to sleep overs, all the regular kid stuff.

When he hadn’t presented by the time he was thirteen, he was pretty much convinced that he was a Beta. When his first heat hit him like a sack of bricks at fourteen, it had been a bit of a shock. He didn’t really remember the details well, but his parents had told him about how he had kicked his father’s ass and had to be restrained.

His doctor had been concerned by the violent outburst, and ran some tests. His hormone levels were apparently similar to that of an Alpha. They weren’t able to determine exactly why, but it didn’t seem to be much of an issue for his health. He had been prescribed suppressants, and started using sent blocking products, and then tried to pretend that nothing had changed.

It had taken a while for them to find the right dosage for his suppressants. For a while he’d been irrationally irritable. Like an Alpha nearing their rut, he’d picked fights with other males at any given opportunity.

One day, he’d overheard some Alphas from a gang of teenage delinquents saying that all Omegas were sluts. Despite being outnumbered, he had managed to send them running. After that, every time he ran into someone from the gang it was a brawl. At first, he lost as often as he won, but it wasn’t long before they weren’t able to take him down anymore.

It was during one such fight that someone pulled a knife on him. His opponent had been about to put it through his stomach, when a female Beta had tazed him from behind. “Come with me,” she’d said to him, “I have a place where you can fight without getting yourself thrown in jail or killed.”

It had taken a lot of convincing to get his parents to sign the consent form for him to start going to the Fight-house, but eventually they caved. His mother didn’t want him to fight at all, but agreed that it was better than getting shanked in a dark alley. His father was convinced that the risk of lowering his dowry with scars was offset by his winnings.

After that he had stopped with the street fights, and managed to get his temper under control. He had been lucky he had managed to avoid getting killed, or killing anyone else… well… except for that one incident, but that wasn'ta brawl. It hadn’t been his fault anyway, it was self-defense, but he didn’t really like to think about it.

Sure, it was a pain to still legally need a guardian to sign off on things as an adult. Moreso because his father didn’t want to allow him to do anything that cost money, and his mother was still trying to get him to live up to the stereotypes.

Even so, he didn’t particularly dislike being an Omega, he’d had a lot of time to come to terms with it. He was undeniably attracted to male Alphas, so being compatible as partners had seemed like it would be a good thing. He hadn’t exactly anticipated that his mate wouldn’t be attracted to Omegas, so that kind of canceled out that positive aspect.

The bald man looked back to his new mate. He could tell, even with the sunglasses, that the other man was staring at him intently, waiting for his answer. He sighed inwardly. He wasn’t really one to give long winded speeches about his backstory, and it wasn’t like his experiences were typical for Omegas.

“Depends on who has custody of you, I guess,” he replied with a shrug.

Chapter Text

A silence settled between the two newlyweds as they ate. Genos got the impression the Omega wasn’t particularly chatty, and the blonde kept thinking about what he had said. “Depends on who has custody of you,” it was only a few words, but they spoke volumes.

The answer had alluded to the complete lack of autonomy Omegas had. He was starting to grasp that the system he had been told was in place to protect and care for those in need of it, was all too easily abused.

He really shouldn’t have been surprised by any of this. It was hardly new information, after all, he had purchased another person for his own purposes. Sure he had good intentions, but his stomach twisted with guilt when he considered the other man’s complete lack of choice in the matter.

He may have acknowledged Saitama as his equal with a two way bond, but there was just so much that the other man was not able to do without someone else giving their permission. The Omega was an adult, seven years older than his Alpha, it just didn’t make sense. The blonde decided he would sign any paper the other man asked him to. Whether he wanted to get a license, a bank account, or anything else, he deserved to make his own choices.

***

It wasn’t long before he found himself signing papers on his mate’s behalf. After they had finished their lunch, the bald Omega had led him to Fubuki’s office to make sure he would still be able to participate in the fights.

When they entered the room, Saitama had casually grabbed a magazine and sprawled across the sofa. Genos moved to sit at the desk, across from Fubuki. A large stack of papers was already waiting for them, apparently she had noticed them in the dining area and expected their visit.

“Demon Cyborg,” she greeted as he sat down, the Alpha frowned slightly in response.

“At least they didn’t call you Caped Baldy,” Saitama said, not even bothering to look up from the page.

“Seems like you aren’t going to keep our champ out of the ring, and you’re not too bad looking either, I guess the result of the auction wasn’t too bad then was it?”

Before Genos could answer, his mate piped up again. “Yeah, we’re… uh… satisfied.” A slight blush spread across the Omega’s face. “I’ll let you gloat about it if you change my nickname.”

Ignoring his request, she gestured to the stack of papers. “So how much are you willing to sign off on? Permission for him to fight, drink alcohol, stay after midnight, bet on matches…?”

The Alpha glared at the stack as if it had personally offended him, and picked up the ballpoint pen she had left next to them. “All of it,” he replied, “anything he wants.”

***

After they finished at the Fight House, the Alpha brought Saitama to the bank as he had promised. The bald man didn’t really pay attention to the conversation as Genos argued with some guy in a suit. In the end, his new mate handed him a card with some papers. “A joint account is all they would offer for an Omega with no credit history. Sorry, I’ll get you set up with your own account in the future. This will give you access to your prize money for now.”

“Huh? Oh, yeah, thanks.” Saitama replied with a slight smile as he slipped the card into his pocket. When Fubuki found out that his father was keeping his prize money, she had let him get more than a little creative with what he could put on his tab at the Fight House, and would just deduct it from his earnings before sending it. He hadn’t been completely unable to use his money before, but the card with his name on it felt different. It felt good to know he could just buy whatever, without having to go through someone to get it. Maybe the first thing he should buy on his own was a wallet, now that he actually had a use for one.

As they drove to what was to be his new home, the bald man kept unconsciously touching the card in his pocket, as if checking to see if it was still there. He was starting to wonder if any of this was real, or if he’d wake up any moment and find himself getting married off to some creep that would treat him like an object. His new Alpha was attractive, considerate, and even took an interest in his fights. He wasn’t sure how an old, awkward, hairless Omega like himself had managed to get so lucky.

***

He wasn’t sure what exactly he had been expecting, but he was still surprised to see his new home. Instead of a house, it was a large rectangular building, mostly filled with different labs and examination rooms, with some living space towards the back of the building. As he followed the Alpha through the hallways, each of them carrying one of the Omega’s suitcases, Saitama glanced through the open doors, and windows into other rooms that revealed complex schematics, sinister looking medical equipment, and… were those rockets?

Had he married a mad scientist? He looked at the other man walking before him as he pondered. Genos didn’t really look like one… the view from behind was… just wow. Broad shoulders, and an ass that looked criminally good in those tight jeans.

As they neared the bedrooms, the blonde gave him a brief tour of the surprisingly normal looking living space. A living room with a comfortable looking leather sofa, a bathroom, kitchen and dining area, they wouldn’t have seemed out of place in a suburban house.

“Here’s your room,” the Alpha said gesturing toward an open door in one of the hallways. It seemed obvious, of course, that they would have separate rooms. This was just a contract marriage after all, that Panic guy (or whatever his name was) had already warned Saitama that Genos didn’t like Omegas, and they hadn’t even mated on their wedding night.

“I’ll let you get settled in. My room is just across the hall, but I spend most of my time in the lab. Just let me know if you need anything.” The Alpha lingered for a moment, with an unreadable expression, seemingly wanting to say more, before crossing the hall and disappearing into his own room, closing the door behind him.

For a moment the Omega looked at the closed door, the abrupt way the other man had walked away, left him feeling a little disappointed. ~Don’t be stupid,~ he chastised himself, tearing his eyes away from the door to look at his new room. What was he even expecting, a kiss? This hadn’t been a date, and the unfairly attractive Alpha didn’t, couldn’t, want him that way.

The room was larger than the one he’d had in his parent’s house, with no clutter, nicknacks, or decorations. A large bed with an expensive looking wooden frame stood on one side of the room, a matching wooden dresser was on the other. Saitama stepped inside, closing his door behind him as he looked around. Opening the door at the back of the room revealed a walk-in closet, with more storage space than he could possibly need for his two suitcases worth of belongings. The soft blue rug in the middle of the room, and matching blue bedding looked a bit plain, but felt like they were probably expensive. When he flopped onto the bed, he could tell the mattress was also, definitely very expensive. It was nice, he was sure that once he was used to it, he could be comfortable there.

The bald man sighed and wrapped himself up in the soft blankets. He would deal with his stuff later, he just… needed some time to process everything that had happened. It had all been so fast, the wedding, learning his new husband wasn’t into Omegas, the bond bites at the hotel, sleeping next to each other, and… oh god… that brief moment at the gym where he had the other man pinned on his back.

That was… a mistake he shouldn’t repeat. He felt a rush of arousal just thinking about it. They way they’d landed with Saitama between his Alpha’s legs, their faces so close together he could feel his quickend breaths, the enticing scent of his newly bonded mate, it was too much. The way those black and gold eyes had widened with surprise before his expression had shifted to… What was that? Sexy is what it was. He’d had to scramble to get up and walk away, because if he’d stayed in that position for even a second longer, he would have kissed Genos.

Hell if the attraction was mutual, and they weren’t in public, he would have done a lot more than that.

Chapter Text

Saitama glanced anxiously toward the closed door of his room when he felt his arousal building. Maybe it was good that he had some privacy. If he had to continue being celibate outside of his heats, he could at least get some relief by taking matters into his own hands.

The Omega quickly went to the door to lock it. Not that he believed it would keep Genos out if he wanted to enter, but it would at least be a reminder to knock instead of busting in on him in the act. Before returning to the bed,he took a moment to remove his clothes. A blush spread across his cheeks and to the tips of his ears. It felt oddly embarrassing to be naked in an unfamiliar place, being so turned on that he would masturbate in the middle of the day just across the hall from his new (unfortunately mostly platonic) life partner, didn’t make it any better.

He climbed back into the bed, pulling the blankets over himself. Oh… those sheets were nice. Saitama didn’t have much in common with other Omegas, but he did share their appreciation for soft fuzzy blankets, silky sheets, and nice pillows. This bed felt good. If he was going to be masturbating frequently (and with the way his mate unintentionally turned him on by doing completely innocuous things like walking or breathing he was certain he would be), he might as well be doing it somewhere comfortable.

He closed his eyes and imagined having the blonde pinned beneath him again, but in the bed they had shared at the hotel. He pictured those golden eyes, and what it would feel like to have those arms wrapped around him. He imagined closing the gap between them to kiss him, like he had wanted to at the gym, and the all too perfect moans he could wring from the other man if he thrust against him to feel the friction of their erections press against each other.

The Omega was already breathing hard as he reached down to grasp his already fully hard member. It had been a long time since just fantasizing about someone had gotten him so worked up. Maybe it was the new bond hormones, or maybe it was the Alpha’s unreasonably good looks and nice scent that did it, but whatever it was, he was already close to the edge after a few light strokes.

He imagined the other man’s legs wrapped around him, and that voice moaning his name. He thought about biting the soft smooth skin of his neck, and grabbing his hips, before pushing forward, into him.

That thought was all it took, stifling a moan with a hand over his mouth, he came. For a moment he was lost in intense waves of pleasure that seemed to pulse through his entire body.

~Did I just get off on the thought of fucking my Alpha? Ah fuck, I’m a pervert~ The thought brought with it feelings of guilt and shame. It was bad enough to be using a near stranger, one who was probably repulsed by him, as “inspiration,” but to take it that far made him feel like a total creep.

The man that had been unfortunate enough to get stuck with Saitama was younger, barely old enough to be married, and not into Omegas. It was also extremely unlikely that an Alpha would ever accept being the bottom.

Hell, now that he thought about it, they’d just bid on whatever Omega they could be sure to win because there was no intention of having a sexual relationship, so there was a possibility that Genos wasn’t even into guys. Straight Alphas sometimes mated with male Omegas, and no one thought anything of it, because they were considered to be feminine enough to be more or less like women.

Saitama looked at the very visible muscles on his torso. There wasn’t anything about him that was soft, round, or feminine. He had never disliked his masculine body, nor hated being an Omega (though he didn’t particularly like the way they were treated), but it made things complicated to be both.

With a sigh he got up to start cleaning the mess he’d made, he had only just arrived and his sheets were already covered in cum and slick. He needed to quit longing for something that would never happen. His new mate had already given him so much more than he’d ever dare to hope, it would be too greedy of him to want for more.

***

As soon as his door was closed behind him, Genos slid back against it to the ground, removing his sunglasses to bury his face in his gloved hands. He could feel the heat of a blush spreading across his cheeks. He’d come dangerously close to kissing Saitama in the hallway. He had very nearly asked Saitama to move into his room, to share his bed… to… oh fuck, the things he wanted to do.

He took a deep breath, trying to calm down, as he reminded himself that he wouldn’t do anything unless the other man made the first move. The Omega was not there by his own volition, and they barely knew each other.

All Genos knew about him was that he liked to fight… well, that and the fact that he had an amazing body. The Alpha didn’t know what he liked to eat, or his favourite colour… he didn’t even know if he liked men.

Sure, Omegas and Alphas were usually attracted to each other, but the blonde knew all too well that things didn’t always work out that way. Sexuality was complicated, and Saitama wasn’t exactly stereotypical for his presentation.

He’d been so sure that the other man wouldn’t be attracted to him because of how damaged he was, he hadn’t even considered that there were other reasons why it might not work.

Still… there had been moments where it seemed like maybe there was something. The bald man’s slight smiles, moments of physical contact that had lingered a little longer than necessary, when the other man had pinned him to the mat… Was there really chemistry between them, or were his instincts leading him to the wrong conclusion?

Those very instincts were acting up yet again, as just thinking about brief moments of contact with the Omega, had him achingly hard. He nervously bit at his bottom lip as he removed his gloves. He didn’t think he could make it through the day without doing or saying something stupid if he remained pent up like that, he’d just have to do something about it.

With a muffled groan he unzipped his jeans to release his throbbing member. He didn’t bother to undress (he rarely did other than when he was showing or changing). As he began to stroke himself, he struggled to stay quiet, and control his ragged breathing. The last thing he needed was for the other man to realize what he was up to.

He leaned forward, kneeling with his free hand braced against the ground as he picked up speed. His mind wandered back to when Saitama had been on top of him, between his legs, pinning him down. In that moment he had been completely and utterly dominated, and he very much wanted to feel more of that. He wanted to feel the other man’s muscular body hold him down, sharp teeth against his throat. God… he wanted… he wanted to be fucked. That thought sent him over the edge, biting his lip to suppress a moan, he came so hard he was seeing stars.

Well shit… he wanted his Omega to top him. Maybe he -was- a pervert.

Chapter Text

After he cleaned up and unpacked his bags, Saitama had stayed in his room, opting to take a nap because he hadn’t really known what else to do. Genos hadn’t really seemed like he wanted to hang out, and the lab was far enough from the edge of the city that there wasn’t really anything worthwhile in walking distance.

Some time later he was roused by a knock at the door. “Hello Saitama,”an old man’s voice called to him, “Genos is making dinner, would you care to join us?”

The Omega recognized the voice from a brief introduction that had taken place during the whirlwind that had been their wedding. It was his Alpha’s dad… doctor? Whatever, the old guy apparently lived there too.

An Alpha actually doing something around the home? He did in fact, want to go see that. With a yawn and a stretch, he got up to join the old Beta on the way to the dining area.

As they made their way to their destination, Saitama slowed his steps to match the old man’s pace, the inviting scent of homemade stew made his stomach rumble. “Does he cook often?” the bald man asked, to fill the silence.

“Oh yes,” the old man replied with a smile, “we’re quite lucky in that regard. He cooks most of our meals here, and he’s quite good at it too.”

As unusual as an Alpha in the kitchen was, what really surprised the Omega, was the sight that greeted him as they rounded the corner. The blonde man stood by the stove, ladling the stew into bowls, wearing a ruffled pink apron over his clothes. He turned to the old man and raised an eyebrow, leaving the question unspoken.

“One of his little friends, Sonic was it? Ah yes I think that’s it. Sonic gave it to him as a joke when he found out how much he enjoys cooking. He wore it to prove some kind of point I think… but… well it’s been some time now, I think he’s just wearing it to keep his clothes clean. He’s quite fastidious that boy…”

As they took a seat at the table, he tuned out, mostly ignoring the old man’s rambling. He listened just enough to know when to nod or add an occasional “uh huh,” to the conversation. His eyes, and thoughts were stuck on the Alpha in the apron. It was… cute. A wholesome, domestic side to his mate that he hadn’t expected. Something about it just felt so oddly comforting, he couldn’t suppress a small sigh.

“I know that look,” the old mad said softly. “Ah, to be young again.”

The Omega sputtered, and blushed, wanting to make some excuse for the way he’d been staring, but before they could say anything Genos had joined them at the table, setting the bowls in front of them. He removed the apron, hanging it on a hook on the wall by the kitchen door, before sitting down across from his new mate.

It seemed there wasn’t much need for formalities in his new home, as soon as the food was on the table, and everyone was seated, the old man, and the Alpha started in on their meal. Following their lead Saitama took a bite. As soon as the flavour hit his mouth, his eyes widened in surprise. “Oh, wow Genos, this is really good,” he exclaimed after he’d swallowed.

“Thanks,” the blonde responded, “my mom taught me to cook. She always said it didn’t matter what someone's presentation is, an adult needs to be able to clean their home and feed themselves.” For a moment, his expression darkened, black and gold eyes fixed on the table in front of him, but his mind seemed to be elsewhere.

The Omega got the feeling that it was probably not the time to ask too many questions, given that his new mate had been adopted, he could assume whatever happened, his mother was no longer in the picture.

“Thanks,” he said instead, “for dinner, but also, y’know…” He gestured vaguely.

“So how are you enjoying your new room?” the old man asked, as if to steer the conversation in a lighter direction.

“Oh, uh, it’s nice,” Saitama replied, between bites of his dinner, “it's really comfortable.”

A sly smile crept across the old man’s face as he turned to Genos. “I happened to notice you decided to go with a different guest room than the one we had prepared on the other side of the living quarters, is there any particular reason why?”

“It wouldn’t have suited his taste,” the alpha replied with a pointed glare at the old man.

“Is that so?” Doctor Kuseno raised an eyebrow skeptically, “well I suppose the floral wallpaper may have been a bit much… although we did have two other guestrooms identical to the one he’s in now, interesting that you chose the one closest to your room.”

“That’s… it was… in case he needs something.”

The Omega had to suppress a laugh. It was all too amusing to see his usually serious looking mate become so flustered. ~Cute,~ he thought again. ~He’s already hot, why did he have to be cute too?~

After that the three of them finished their meal, the old man rambling on about back in his day, this, and biomedical engineering, that, the entire time. Saitama wasn’t really paying attention to what he had to say. Soon enough, Genos was gathering up the dishes, and the old man was wandering off back to the lab where he seemingly spent the majority of his time. “I’ll leave you two young’uns to enjoy your honeymoon,” he’d called back to them with a wink, as he slowly made his exit.

Not knowing what else to do, the bald Omega joined his mate in the kitchen, cleaning the dishes and putting things away together in a comfortable silence. It was different from what he was used to, in his parent’s house the atmosphere had always been tense. His dad was, simply put, an asshole, and his mother was… well… He loved her, but she was a bit… too much.

When everything was done, they had gone to the living room. After a long day, neither of them felt like doing much, so they had opted to watch TV. As they settled in on opposite sides of the sofa, the Omega let out a small sigh of contentment. He wasn’t sure exactly what it was that they had going on between them, but whatever it was, it was causing a warm feeling to bloom in his chest.

***

The first things Genos was aware of were darkness and the sensation of burning. His entire body felt like it was on fire. Maybe it was, he couldn’t see anything, it was so hard to discern what was happening. The searing pain in his eyes was agonizing, he had never felt anything like it.

He tried desperately to reach up and rub away whatever was burning his face, but… oh god… he couldn’t move his arms… he couldn’t even feel them. Oh fuck… the pain seemed to stop right at his shoulders. Did he even still have arms? They were… gone, weren’t they?

He tried to move his legs, to roll to extinguish the flames, but they were pinned beneath something. The steel beam, he remembered. It had landed on him when the building collapsed in the fire. ~Shit,~ he was trapped ~shit, shit, SHIT!!!~

He heard voices screaming around him, he would be screaming too if he could draw enough breath to make a sound. With each labored gasp for air, he could feel something deep in his chest bubbling, and the heat from the air burned as he inhaled. His nose filled with smoke and the scent of burning meat.

As he lay helplessly consumed by agony and fear, he could hear someone laughing maniacally in the distance.

***

“Genos,” someone was shaking him, “Hey Genos wake up!”

The Alpha sat up with a sharp gasp, to realize he had been having the same nightmare, reliving the same terrible memory, yet again. He placed a shaking hand against his chest, as if to steady himself, as he struggled to slow his breathing.

“Are you alright?” Saitama stood at the side of his bed, dressed in just a pair of striped pajama pants, eyes wide with concern.

“Yeah, I’m… I’m fine,” the alpha lied. He wasn’t alright, but he was used to it. Waking in the night shaking and covered in a cold sweat, had become just part of his routine. He’d been reliving that horrible day in his dreams for years. “How did you…?”

“I could feel your distress through our bond.” The bald Omega answered with a shrug.

The Alpha felt as if someone had doused him with ice water. He had known that the bond would alert his mate if something was wrong, but he hadn’t realized that dreams were something that could trigger it. If he had known, he might have reconsidered the two way bond, or at least given the other man some kind of warning. He should have let him decide for himself if he wanted it. “I’m… I’m sorry,” his voice felt weak, hardly more than a whisper.

His mate reached out, placing a hand on his cheek and gently turning Genos to face him. “Are your tears supposed to be like that?” Genos felt his face heat up, flushed from the embarrassment of realizing he’d been crying in his sleep, leaving streaks of black liquid running down his cheeks.

“Yeah that’s… normal… for me anyway,” he mumbled, pulling away from his mate's touch to attempt to wipe away the marks. When he was done, the Omega reached out again, swiping away what he had missed.

The blonde looked at the digital clock on his bedside table and groaned. It was only three in the morning. Most of the time, he was lucky enough to sleep until five, or even six, before the nightmares woke him up. He usually couldn’t rest again with the adrenaline coursing through his system, giving up on sleep to start his day, but this time it was still too early.

“Hey,” his mate shifted his weight from one foot to the other nervously, “is it alright if I spend the rest of the night with you?” The Alpha’s eyes widened in surprise at the request. “It’s just, I feel like I don’t want to leave you alone right now… I don’t know, I think maybe it’s because of our bond or something… It’s not, y’know, anything weird.”

Genos nodded and shifted to one side, making space for his mate to join him in the bed. He was surprised again when Saitama pulled him into his muscled arms to rest against his shoulder. “It's just… I heard that a bonded mate’s scent can be calming,” he mumbled. The Alpha nodded, and made no move to pull away.

Sure enough, as the Alpha breathed in the scent of the forest after the rain, while feeling his mates strong arms wrapped around him protectively, he felt the tension quickly melting away. It wasn’t long before his mate’s soft, rhythmic breathing lulled him into a deep, blissfully dreamless sleep.

Chapter Text

As Genos slowly roused from his slumber, comfortably using his new mate as a pillow for the second morning in a row, he was filled with a mix of complex emotions. On the one hand he was wracked with guilt, knowing that he’d unintentionally made it so that the other man would also wake up with his constant nightmares. On the other hand, Saitama had asked to sleep in his bed, and it was absolute bliss to wake up in his arms.

He lay there for a while, content in the warm embrace, just watching the rise and fall of the Omega’s chest as he breathed. He let himself savor the moment, not knowing if there would be more mornings like that. He took a deep breath, inhaling the comforting scent of his mate, before he stretched and got out of bed. He quietly grabbed some clothing to bring with him to another room to change, then slipped out into the hall, carefully closing the door silently behind him.

After he’d stopped by the bathroom to get ready for the day, he’d made his way to the kitchen. As he pulled his pink apron over his clothes, he debated with himself over what to cook for breakfast. Bacon and eggs seemed to be liked by most, but he didn’t know how Saitama liked his eggs. Pancakes maybe? Did the Omega prefer waffles? He wasn’t sure if the other man liked a big hearty breakfast, or preferred to start his day with something light.

Eventually he went with his first idea, bacon and eggs. Scrambled eggs were generally well liked. The bald man had mentioned that he ate quite a bit of protein to maintain his muscular physique.

The Alpha felt his cheeks flush at the thought of the other man’s body. Saitama’s strong arms and chiseled torso were enough to make him feel weak at the knees. Yes, he -really- liked his mates body, but as they spent time together he was discovering there was more and more to like.

His face seemed plain on a first glance, but his brown eyes, and varied expressions were, in fact, quite charming. His voice, his hands, his scent, his casual body language, it was all absolutely captivating.

Genos sighed and shifted his thoughts back to what he was doing. He didn’t want to risk burning the eggs by getting too distracted

***

Saitama stretched and yawned, then snuggled back deeper into the blankets. He wasn’t tired enough to go back to sleep, but he was just so comfortable he felt reluctant to get up. His new bed was just so soft and warm and it smelled nice… wait… it smelled like… Genos?

He sat up and looked around, getting his bearings as he pieced together his memories from the night before. He’d felt intense distress through their bond, and rushed to the Alpha, only to find him in the middle of what appeared to be one hell of a nightmare.

He felt his face heat up as he remembered how he had asked if he could sleep with Genos for the rest of the night, how he’d clung to him as if the Omega had been the one in need of comfort. He’d said that it was because of the bond, but he didn’t really think that was the cause.

As soon as the other man was awake, his instincts had stopped signaling the alarm. No, it wasn’t some compulsion from the bond when he saw Genos with shaking hands and tear streaked cheeks, he had just.. wanted to hold him. Now it was morning, the sun was shining in through the window, and he was in the Alpha’s room feeling like he may die from embarrassment

He sighed and got out of bed, taking a moment to put the blankets and pillows back in order. His mate’s room was more or less the same as his. The only differences were the shelves lined with textbooks, and a desk covered in papers and tools.

Once he had finished making the bed, he returned to his own room, to change into something he could wear to workout. After breakfast he would see if Genos was interested in going to the gym, and if not, he would just do some calisthenics and go for a run.

As he finished getting dressed, he noticed one last thing he hadn’t yet unpacked. Still lying at the bottom of his suitcase, because he wasn’t quite sure what he wanted to do with it, was the pill bottle that contained his suppressants.

He hadn’t taken one the day before, but if he took two of them with breakfast, he would have enough in his system for them to keep working. He subconsciously ran a hand over his bald head. The side-effects had already started to catch up to him, the whole point of getting married was so he could stop taking them, but… were they ready to deal with his heats?

Being bonded had solved one problem, but it would cause another. His instincts would no longer drive him to go seek out some random Alpha, but they would drive him to seek out -his- Alpha. Saitama had never experienced an entire unsuppressed heat, so when it hit, it was going to be intense. It felt like a lot to ask of someone who didn’t even like Omegas.

He slipped the bottle of pills into his pocket with a sigh. He would need to talk to Genos about what he wanted to do. He felt awkward and uncomfortable just thinking about it. How exactly was he going to get through a conversation about heat cycles and sex with an unreasonably sexy Alpha he’d known for only a couple of days?

Leaving his bedroom he walked in the direction his bond indicated he would find his mate. He didn’t get far before it became unnecessary to follow it, because the smell of bacon and sound of sizzling led him to the kitchen. He found his mate, standing in front of the stove, again wearing that adorable apron.

“Hey, uh, Genos…” he started. “There’s something we need to talk about.”

“Right, yes, just a moment while I finish up,” the blonde replied, “Dr. Kuseno is usually already working on something by this time of day, so we can talk over breakfast.”

Saitama sat down at the table, watching as the Alpha finished plating everything and pouring coffee. His heart was pounding in his chest so loudly he worried the other man could hear it. He hadn’t been nervous about a fight in years, why was it so much more anxiety inducing to have a conversation?

“So,” Genos asked as he set down the plates and took a seat across from his mate, “what was it that you wanted to talk about?” His voice was calm, but the Omega could tell he was concerned by his furrowed brow, and how he nervously bit at his bottom lip after asking.

The Omega pulled the bottle of pills from his pocket and rolled it across the table to his mate. “What should we do about this?”

The blonde examined the bottle, eyes widening as he read the prescription on the label. “Your suppressants,” he said, looking back up at Saitama. “You got married so that you wouldn’t need to take these anymore.”

The Omega nodded, “that’s what my parents decided. What do you think we should do?”

The Alpha looked back to the bottle in his hand, seeming to consider his reply carefully before answering. “We don’t know what complications there may be if you continue taking them. I can tell you from experience that organ failure is an…” the blonde unconsciously ran a hand over his torso, “undesirable outcome.” He rolled the bottle back across the table to his mate. “I won’t tell you what to do… but… I’m asking you to throw them out.”

“Sure,” the bald man shrugged, trying to seem casual, though the heat of his cheeks told him he was probably turning red, “but that means we won’t have long before…”

“Saitama,” his mate replied, golden eyes fixed on the plate in front of him, “I… was aware of what I was getting into when I chose to marry an Omega.”

“Wait…” the bald man felt a little flutter of hope, “I thought you didn’t have a choice.”

“If I wanted a partner with no heat cycle, I could have married a female Beta,” the Alpha scowled at the thought, “but… I am not attracted to women.”

Chapter Text

Saitama sighed as the hot water from his shower ran over him. He had barely been able to focus when they were at the gym, his mind replaying the conversation they’d had over breakfast. He’d been so distracted that Genos had even managed to land a hit on him while they were sparring.

He raised a hand to touch his cheek where the strike had reached him. It hadn't particularly hurt, the mark had faded before they’d even made it home. The Omega chuckled, the look on the other man’s face had been worth it. Genos had just stopped in his tracks, eyes wide, and mouth agape. Shocked that Saitama hadn’t dodged or blocked, and even more so that he took being decked in the face with barely so much as a flinch.

Their discussion that morning had gone well… better than he’d expected. A blush crept across his face. Genos hadn’t shown any signs of reluctance or disgust when it came to helping him through his heats. His mate had even said that he liked men. That didn’t necessarily guarantee that he would be open to physical intimacy outside of when it was necessary, but it certainly improved the chances.

His mate would be taking his virginity when his heat came, possibly as soon as some time in the next few days. He felt himself start to harden at the thought. It would be a shame that he wouldn’t be entirely with it when it happened. The drug-like effect of the heat would leave him with only hazy memories afterwards. He had been disappointed that he didn’t really remember putting his dad through a wall, but the thought that he might not remember his first time with Genos was killing him.

His eyes fluttered shut as he tried to picture what it would be like to have the Alpha touching him while he was hot and desperate. He imagined his mate’s hands on his skin, duplicating the motions with his own. A shiver ran up his spine and let out a muffled whine as his fingers brushed over his sensitive nipples.

His breathing quickened as his hands wandered lower, leaving a trail of warmth behind them. When his heat came, he would want to feel his Alpha inside him. He whimpered at the thought, imagining himself face down on the mattress, and Genos's hands holding onto his hips as he pushed into him.

Saitama wrapped one hand around his member, his hips jutting forward unconsciously at the sensation. He hesitated a moment, before reaching the other hand around behind himself to brush his fingers up against his hole. He hadn’t tried touching himself there before, but he wanted to know what it would feel like to have Genos inside him.

He circled around it at first, shuddering, feeling how he was already dripping with slick. After a while he slipped a finger inside, gasping at the unfamiliar sensation. His other hand sped up, stroking himself hard and fast as he tried to picture what it would be like to be pounded from behind. He added another finger, moaning as he made a scissoring motion to feel the stretch of it.

Fuck, it felt good… but it wasn’t enough. Genos would be bigger right? He added a third finger, whimpering in frustration as the angle made it difficult to reach as deep as he wanted. It was too much, and not enough, and it felt like his whole body was on fire with the need for it.

“Ah… nnnh… oh fuck,” He tried to keep quiet, but he couldn’t stop himself from moaning and cursing as he reached his climax, his whole body shaking with the intensity of it.

He shuddered at the feeling of the water hitting his now sensitive skin, and finished getting cleaned up. He hurried to get out of the shower and get dressed, hoping the Alpha wouldn’t notice how long he’d been in there.

***

Genos was walking, hamper of dirty clothes in hand, toward the laundry room when he heard a muffled whine coming from the bathroom. He could hear the fan, and the water was still running, meaning Saitama had been in there for quite a while.

He was about to knock on the door to check if the Omega was alright, when he heard a series of low breathy moans. His eyes widened with the realization of what was going on. Oh, that was… the sound sent a hot jolt of arousal through him.

Nervously, he backed away from the door. As much as he wanted to hear more, he was more afraid of being caught listening. He hurried to his destination, trying unsuccessfully to ignore the sudden tightening of his pants.

Chapter Text

They met up with Mumen and Sonic at the fight house for supper that evening. This time, they just wore their regular clothes, as most of the fighters only bothered to wear costumes for special events. Saitama wore a simple plain yellow t-shirt and loose fitting jeans. Genos was wearing a black button up dress shirt, with tight jeans that fit him so well the Omega could hardly keep his eyes off of him. When the Alpha added his usual gloves and sunglasses to his ensemble before they left, the bald man felt a slight pang of disappointment. He would have preferred to see his mate’s intense black and gold gaze that made him feel like he had butterflies in his stomach.

After spending the majority of the day, after going to the gym and showering, in one of the lab’s examination rooms being poked, prodded, and scanned by Dr. Kuseno, Saitama was relieved to be going just about anywhere else. He understood the concern, but it had been just so incredibly boring.

He hoped that there would be someone decently strong for him to fight for once, though the chance of that was pretty low on a Monday. On the weekends there were usually events, tournaments, or strong fighters being brought in from out of town, but on weekdays it was just whoever happened to be at the bar issuing challenges to each other. It was mostly just amateurs taking out their aggression on each other, and some small-fries trying to improve their rank.

He ignored the conversation going on around him and gazed blankly at the menu that was on the table in front of him, he had already memorized it anyway. Maybe it would be interesting to watch the others fight. Genos had hopefully learned a thing or two from sparring together, and Mumen’s matches tended to be… memorable. He cringed a bit thinking about some past matches where the brunette had been absolutely pummeled. Even Manic, though he wasn’t all that strong, was kind of cool to watch because of his flashy martial arts moves.

“I already knew that Saitama’s an Omega,” that certainly got his attention. His gaze snapped up to regard the glasses clad Alpha. “I, uh, met your mom at one of my charity meet and greet events,” Mumen elaborated.

The bald man sighed, of course, Mumen knew everyone. “Let me guess, she said a bunch of stuff that’s absolutely mortifying.”

“You would probably think so, yeah,” he replied, “She was trying to talk me into marrying you, but I was already dating Sonic so…”

“Is that the only reason you weren’t interested?” The dark haired Beta interrupted, his posture reminding Saitama of a cat with its ears back and fur puffed up.

“Ah, well…” Whatever he was about to say was cut off by a sharp glare from Genos. Not wanting to risk angering either his boyfriend or the other Alpha, the brunette glanced around the room for an excuse to dodge the question. “Oh there’s King, I needed to talk to him about something.” Mumen got up and walked quickly, practically scurrying, to go speak to the imposingly large, blonde man that was on the other side of the room.

“This conversation isn’t over,” Sonic grumbled before following him.

“He looks tough,” Genos said, looking at the man they had gone to speak with, “have you fought him?”

The Omega snorted, barely holding back laughter. Sure, King looked intimidating with his sharp facial features, and three scars across his left eye, but there was no way he would ever get into the ring with Saitama. “No, he’s just here to hang out and bet on the fights,” he leaned toward his mate and lowered his voice so only Genos would hear him, “and just between us, I think if I challenged him, he’d wet his pants.”

As the night went on, it started to feel like they were on a date. The Omega actually made an attempt to be engaged in the conversation as Genos asked him a bunch of questions about things like what he likes to eat, and what kind of activities he enjoyed. Saitama even asked a few questions himself, surprised at his own interest in talking at length with someone else. It felt nice to actually take some time to get to know each other.

Mumen and Sonic had returned to their table at some point, but the newly bonded pair hardly paid any attention to them, lost in their own world.

The warm feeling in his chest was back, and growing stronger every time he was aware of it. Was this what it was like to fall for someone?

Before his thoughts could spiral down into anxious uncertainty about if his feelings were reciprocated, someone grabbed one of the microphones that was set up by the side of the stage.

“Hey Saitama,” it was one of the lower ranked fighters, with his hair dyed in black and orange stripes, with a matching pattern on his top, “what’re you doin’ here?… You -fraud-.” The Omega looked at him with his usual, disinterested expression. ~What was that guy’s name again?~ He pondered, not really caring about the answer. ~T-Shirt Tabby or something?~ It didn’t really matter. “Yo Bro!” The stripped Alpha called out to someone in the crowd.

Another Alpha, this one wearing a black top joined the first and took hold of the mic. “Did you call, little Bro?” Ah, so they were a tag team then. What was the other guy's name? T-shirt Asshole? No, that didn’t seem right.

“Aren’t you an Omega?” The guy was yelling into the mic, clearly trying to draw as much attention to them as possible. “It’s not possible that someone like you could have gone undefeated for years without cheating. I can’t believe you would do such a thing.”

Genos started to get up, clearly intending to say something, but Saitama stopped him with a hand on his shoulder, pushing him gently back into his seat. It wouldn’t help to have his Alpha go trying to fight his battles for him, and the bald man was more than used to being challenged.

The guy in the black tank top continued hurling accusations, saying Saitama was somehow using his Omega pheromones to cheat, or that the matches were rigged, and saying that he should quit being a fighter.

The bald man barely bothered to listen. He turned to Mumen, “how strong are these guys?”

“I don’t actually know everyone, you know that right?” The brunette seemed to think about it for a moment before adding, “I did beat them about four months ago though.”

Saitama sighed, no offense to his friend or anything, but if Mumen could beat them, they were pretty weak. Still, with the way the crowd was turning on him, chanting for him to “give it up,” and “get lost,” seeming to believe their accusations, he would have to accept their challenge. It was time to remind everyone how he became the local champion.

“If you’re a real fighter, then face me like a man!”

“Sure, I’ll fight you guys” he replied, and the match was set. The tank top clad Alpha spent the ten minute delay before the match still yelling and hyping the crowd up. Saitama spent it staring at the ceiling, disinterested in what he had to say.

When the match started, the Omega took his usual stance, standing casually, arms at his sides, waiting for his opponents to make the first move.

The guy with the stripes went first, rushing in with his arm pulled back for a haymaker. Unimpressed, the bald man simply hit him hard enough to knock him out of the ring.

***

Genos was absolutely livid, who the hell did these guys think they were? Anyone who fought against Saitama would have been able to tell them that he had earned his place at the top of the food-chain.

Satoru passed him a drink, unphased by what was going on in the ring. “Don’t worry, Saitama’s used to this kind of thing. He’s been a heel since he first started fighting.” The brunette looked thoughtful for a moment. “I don’t think he was actually trying to be one though. I think people just don’t like how fast his matches are, he doesn’t usually bother to put on much of a show.”

“What is a heel?” He replied without taking his eyes off of the Omega as the competitor in the striped shirt approached.

“It’s somebody the crowd loves to hate,” Sonic answered, “an antagonist that gets the fans riled up. I’m a heel too” that grin of his seemed to spread across the entire width of his face, “and I’m going to make sure they hate me even more than him. I can’t have my rival taking the number one spot in everything.”

Clearly the long-haired Beta was proud of that, but the blonde wasn’t sure why it was something to brag about. “You… want them to hate you?” He asked with a raised eyebrow.

“Obviously,” the Beta replied flippantly, “people get more invested in the fights that way. It gets dumbasses to bet that you’ll lose even when it’s a sure thing. It brings in tons of money.”

Although Genos now understood the concept, he didn’t think it made sense for his mate to be disliked. Saitama was so unbelievably strong, and surprisingly gentle, he should have fans instead of haters. The Alpha already knew he would end up trying to sway opinions anytime he met someone that didn’t understand how great Saitama was.

He wasn’t even remotely surprised when the stripe-clad Alpha was batted from the ring, as easily as one would swat a fly.

He watched with interest as the second opponent attempted an obviously telegraphed grapple. They hadn’t wrestled much, so he wasn’t sure if the Omega would counter the move differently, or simply punch this one as well.

As it turned out, the bald man simply grabbed onto one of the man’s extended hands, threading their fingers together, and tightened his grip. The black-haired alpha instantly dropped to his knees. “I-I give up!”

“Huh?... nah, you’re kidding me.” The Omega deadpanned, clearly unimpressed with how easily his opponent had caved.

“I really give, I’m sorry,” the alpha shouted, tears starting to well up in his eyes from the pain, “I’m sorry I said all that stuff about you being an Omega.”

“I am an Omega, though,” Saitama responded, releasing his opponent, before turning to point at the crowd that was watching in stunned silence, “If you got a complaint, then come up here and let me hear it!” He raised his voice enough that he could be heard throughout the bar, even without the mic.

Someone in the crowd yelled back “But Omega’s can’t…”

“Shut up! Tell that to my track record idiot!” The bald man snapped, cutting off the heckler. “I don’t fight because I want your approval, I do it because I -want- to! What do I care about your precious egos? If you wanna hate me, then hate me! You Baldies!”

Genos couldn’t help but to laugh at the Omega’s choice of insult. He felt his tension melt away when he realized his mate did, in fact, have everything under control.

Chapter Text

Amai sat in his office glaring at a tabloid magazine that sat open on his desk, opened to the center page story. There in the middle of the page was a picture of his cousin’s wedding, surrounded by smaller paparazzi photos that had been stealthily taken outside of a gym and at the Fight-House. One of the pictures was zoomed in with a yellow circle around where the bite mark on the blonde’s neck was peeking out from under the collar of his shirt.

Each paragraph featured headings like “love at first sight,” and “is that -really- an Omega?” There was no mention of the fact that he, an actual A-list celebrity, had made an appearance at the wedding.

His brooding was interrupted by the sound of a notification on his phone. As he read the message, he felt his blood pressure rise enough to make veins pop out on his face. One of his contacts at the Z-City fight house had let him know that the Omega had not been phased when the crowd chanted for him to quit. More frustrating, he had won the match against fighters that Amai had paid off, confirming that the bald man wasn’t cheating, not against small fries anyway.

He had contacts at most official locations, he had to make sure the league maintained a decent reputation, he was the idol who was also a fighter after all. He hadn’t been aware of “Caped Baldy,” before the wedding. Normally he wouldn’t concern himself with the local champ in some little hole-in-the-wall bar, not unless they made trouble when traveling to other, more relevant locations.

Now that he had married Genos, the Omega was suddenly the topic of every forum about the sport, and somehow their relationship became the main focus of all the celebrity gossip columns.

He repressed the urge to throw his phone in a fit of rage. He still needed it, he was going to have to make a call. If the bald man was too shameless to be pushed out of the public eye, the blue haired idol would just have to move onto plan B.

He called one of his contacts, eye twitching with his agitation while he waited for them to answer.

“What do you want? I already told you I’m not going to take a dive for you, pretty boy.”

Biting back an angry response, he switched to his friendly persona that he used when dealing with the public. “Oh no, it’s nothing like that,” he said, “quite the opposite in fact. I’m using my connections to arrange a little event in Z-City and I need you to go. I’m certain that you’ll win, I just have a few simple requests. I’ll make sure you’re well compensated.”

“I’m listening.”

“The fighter known as Demon Cyborg, has prosthetic limbs, both arms, and legs from the knees down. I need you to break them, so he can’t interfere. Mumen Rider has been an annoyance, and he doesn’t tap out. Do be sure to have a little fun with him, before you force him out of the ring, won’t you?” The idol looked down at the magazine again, his fake-friendly tone slipping, “The Omega, Caped Baldy, make sure he has an unfortunate accident.”

***

For the second night in a row, Saitama was awakened by his instincts screaming at him that his mate was in danger. He knew it was likely another nightmare, and hesitated for a moment, unsure if the Alpha wanted his help, before deciding to go wake him up anyway.

He hurried across the hall and into the blonde’s room, hesitating again for a moment, before shaking him awake. “Genos. Hey, Genos!” The Alpha groaned and sat up, burying his face in his hands.

“I’m sorry,” he mumbled weakly.

The Omega shrugged, “Don’t worry about it, just…” He gestured for the Alpha to move over, and joined him on the bed. “Does this happen every night?”

“Yes,” the blonde sighed, “every night.”

Saitama settled down onto the pillow behind him and pulled Genos down to rest on his shoulder again. “You seem to sleep fine when we're together. I wonder if it's because we're bonded.”

After waiting for the Alpha’s breathing to slow to a normal rate, Saitama asked a question he usually avoided as much as humanly possible. “Do you want to talk about it?”

Apparently Genos, did in fact, want to talk about it. The Omega listened intently as his mate told him about the night that he had lost his family and much of his body, about the grueling recovery, and the nightmares those experiences had left him with. Just listening to his story was painful, he couldn’t even begin to imagine what it had been like to live through it.

A hot rage began to build in him, it was probably for the best that his mate said the Mad Pyro was already dead, because if he wasn’t Saitama would have… wait… Mad Pyro…? Oh.

“Um… Genos. There’s something I think you should know… When I was seventeen, I… accidentally killed someone.”

He took a deep breath, nervous from the Alpha’s sudden silence, before recounting what had happened.

He’d been on his way home from the Fight-House one evening, it was only just after five, but underage fighters had to clear out early. He was looking forward to his birthday, when he would be able to stay later. He would also be able to start fighting against the adults, the other teenagers hadn’t been able to beat him for some time, so he was looking forward to a decent challenge.

He was only a few blocks from his house, when all hell had broken loose. There was fire and debris everywhere and people ran screaming in all directions. There, amidst the chaos, some guy was shooting balls of fire from some kind of flamethrower… gun… thing. He didn’t know what the hell it was because he’d never seen anything like it.

Not knowing what else to do, he ducked behind a stone garden wall. Hoping that he could hide until the attack was over. He crouched low, trying not to breathe in the smoke and dust that quickly accumulated in the air around him. He watched with building horror as the attacker launched the fireballs at houses, laughing like a maniac at the resulting explosions. He wanted to look away, to cover his ears and block out the screams that rang out around him.

What the hell was going on? Was it some kind of terrorist attack? An alien invasion? Had he finally snapped, and was just hallucinating the whole thing?

As the man approached, he pressed himself back against the wall. He was shaking, his heart pounding so loudly he was scared it would give him away. He listened to the sound of footsteps as the lunatic approached. He covered his mouth with his hands, not even daring to breathe, as the steps passed him by, just on the other side of the wall.

He probably could have simply escaped, if he hadn’t accidentally kicked a can that was on the ground beside him, causing it to fall over with a clatter. Before he could even process how screwed he was. The attacker jumped the wall and pointed the barrel of that strange weapon at his face.

Now that they were close, Saitama was able to get a better look at the maniac that had obliterated half the block. The guy was wearing a bulky orange heat resistant outfit, a large helmet, and some kind of gas mask obscuring the bottom half of his face. The part of his appearance that stood out in his memory, after years of trying to forget, was the eyes. Eyes like that of a large cat playing with its prey. They held no guilt, no remorse, they were filled with nothing but joy and killing intent.

The guy was laughing, saying something about how he loved to use his weapon at close range. Saitama, wasn’t usually one to let people go on long winded speeches, but this time it worked to his advantage, giving him a moment to think, to come up with some solution.

Noticing the weapon was attached to a huge backpack by some kind of hose, he decided to try seeing if he could disable the weapon if he broke the connection. It was risky, but he didn’t have the time to think of anything else. If he didn’t try, he’d be killed, so he might as well go down fighting.

Fueled by pure adrenaline, he moved faster than he realized was possible, ducking under the crazy guy’s arm to get behind him. As soon as he was behind his attacker, he grabbed onto the hose-like part with both hands, bracing a foot against the main body of the device. Before his enemy could retaliate, he put all of his strength into hauling back on it. He later realized that he had pulled so hard that he tore a muscle. After a brief, terrifying moment of uncertainty, with the man trying to turn to take aim at him again, it ripped free of the machine.

As Saitama fell backwards, the guy let out a barrage of curses and insults. He started trying to remove the straps that held it to his back. Before he could free himself, with a loud bang that left the Omegas ears ringing for days after the incident, the machine exploded.

It hadn’t been a big explosion, it didn’t need to be. Strapped directly to its final victim the device sent shrapnel flying through the Mad Pyro’s body. Saitama had watched in shock as the man's face went slack, and the body slumped to the ground, blood oozing from the holes in his torso.

He didn’t feel bad for killing the guy, not really, it seemed pretty clear that he deserved it, but he had been a bit worried he would get in trouble for it. Thankfully, the authorities understood that it had been unintentional, and even if it wasn’t, it would have been self-defense.

He had been able to avoid having his name or image included in any of the media coverage, being a minor, and an Omega, worked in his favor when it came to wanting to protect his identity. Only his parents knew what happened, and they thankfully agreed that the best course of action was to cover it up.

Like everything else that he was struggling with, he had just pretended it didn’t bother him, and moved on.

When he finished explaining what had happened. Genos embraced him tightly, seemingly at a loss for words. After a long silence, he said “you really are full of surprises, aren’t you?”

It was a while before either of them could sleep, each lost in their own thoughts.

Chapter Text

Saitama yawned and stretched before shifting to a sitting position on the couch. He hadn’t intended to take a nap, but apparently he fell asleep at some point. It was probably fine, it wasn’t like they had any other plans for the afternoon.

They had spent the past couple of days doing little other than going to the gym and hanging out in the living quarters. After learning that the Alpha’s nightmares happened every night, Saitama had started just going to bed in his mate’s room at the end of the day. He had claimed it was because they both slept better that way, but if he was being honest with himself, it was also just because he liked it.

Thankfully, it seemed that his new mate was content with the arrangement as well. He never would have guessed that the Alpha liked to cuddle based on his first impression. The blonde had a softer, cuter side to him that Saitama couldn’t help but to find endearing.

It was the sort of lifestyle he used to think was boring, but with his new mate for company, he found that he was enjoying himself anyway. Living with the Alpha just felt comfortable. He liked to think that Genos was content with him there too.

Dr. Kuseno seemed to spend all of his time in the lab, mostly only joining them for meals. Saitama didn’t mind being around the old Beta, but he did mostly tune out the long winded conversations he had with Genos. They would be talking about some experimental technology that he didn’t understand, or the Alpha would talk to him about how he intended to put pressure on their political connections about something. The bald man didn’t have much interest in politics, but from what he understood it seemed that they were trying to get some legislation changed to give Omega’s more rights or something.

It was strange how quickly he had begun to think of that place as his home. It was only Thursday. He was there less than a week. Something about the place, or more likely the Alpha who lived there, made him feel like he had been wrapped up in a warm blanket.

He glanced at the tv, noting with some concern that there was yet another news story about arson. This time it was at the headquarters of some tabloid magazine. He looked to where Genos sat on the floor beside the coffee table that was covered with tools and parts, as well as some devices that projected holographic displays. The Alpha was scowling at the TV, the tools in his hands seemingly forgotten.

The bald man gave a slight frown, brows furrowing with concern. After what they had discussed a couple of nights ago, it was clear that the last thing they needed was to be thinking about another pyromaniac. He grabbed the remote and flipped off the TV. “So what are you working on?” He asked, more to change the subject than out of genuine curiosity.

The Alpha pulled his attention back to the assortment of tools and parts that were spread out in front of him. “Just a… personal project of mine,” he replied, “Attempting to improve the aesthetic qualities of certain parts, without compromising their functionality.”

Saitama leaned forward, over the blonde’s shoulder to get a better look at what he was working on. When he noticed the small patch of synthetic skin, in a shade that matched the Alpha’s skin tone, and a nearly natural looking blue cybernetic eye, he felt his stomach drop.

“I guess,” he started, trying to sound casual, “some people would prefer to match their skin tone, but you should keep the black as an option.” Genos shifted to look at him questioningly. “It looks cool,” the Omega shrugged.

Saitama felt his attempt to feign indifference start to crumble at the surprised expression on his mate’s face. He placed a hand to the Alpha’s cheek and asked, “were your eyes blue Genos?”

The blonde man nodded slightly, then after a brief silence added, “I’ve been told that the black and gold makes eye contact… off-putting.” The Alpha’s expression seemed neutral, but the way he nervously bit at his lower lip after speaking revealed that it bothered him more than he let on.

“Your eyes look intense,” the Omega replied, and pulled his mate into a hug, the angle made slightly awkward by his position on the sofa. “I like it,” he added softly, almost whispering. The other man was tense for a moment, before Saitama felt his muscles relax as if the Alpha had practically melted into his arms.

He let the embrace linger for a moment, savering the warmth of the other man against him, before reluctantly moving away. He worried if he stayed in that position too long, he would do something to make a fool of himself.

***

Genos had spent the majority of the day cleaning and doing meal prep in an attempt to dissipate his mounting anxiety. It was Friday, and there was still no sign of Saitama’s heat. It wasn’t outside of the average timeframe just yet, in cases of long term suppressant use it was known to take longer. Still, he found himself fussing over the Omega, frequently checking his vitals and his scent.

He tried to keep his thoughts about his mate’s upcoming heat focused on what it meant for the other man’s health and well-being. He told himself to focus on preparing so that he could make sure Saitama would be comfortable. His mutinous hormones kept pulling his thoughts in other, less decent directions.

Since the Omega had started going to bed in his room, it seemed like some boundary between them had been dissolved. The other man had started initiating physical contact more frequently, sitting shoulder to shoulder on the sofa, hugging him, a casual pat on the shoulder, a hand on his hip to move him out of the way, and the way they slept wrapped up in each other’s arms. He loved every second of it, but it was also driving him crazy.

Before the wedding, he had assumed that when his Omega’s heat came, he wouldn’t be affected by it, that he would be able to remain clear-headed as he did only what was necessary. That didn’t seem likely anymore, even when he wasn’t in heat, Saitama smelled amazing. He had no doubt about it, when his mate’s heat hit, it would put him into rut.

A cracking sound pulled his attention back to what he was doing. He had dropped an egg on the floor. With a sigh, he grabbed some paper towel to start cleaning the mess up.

“Hey Genos,” the Omega strolled into the kitchen just as he was kneeling down to wipe up the egg. “Hold on,” the bald man said, and rummaged in the cupboards until he found the salt. “It absorbs the moisture, so it’s easier to wipe up,” he explained as he poured some over the egg that had splattered on the floor.

“Anyway,” the bald man continued, “there’s someone from out of town coming to our Fight-House tonight…”

Normally the blonde would be quick to agree to anything Saitama wanted, especially if it involved watching him fight, but the Alpha hesitated. As he finished dealing with the mess and turned to wash his hands, he asked, “how are you feeling?”

“I’m fine,” the Omega replied with a shrug. The blonde stepped closer, placing a hand on the other man’s forehead to check his temperature. “Maybe a bit of a headache, but that’s it though.”

“When did it start?” the Alpha asked, before leaning in close to his mate’s neck, inhaling deeply to check his scent. So far, there was still no change. He was struck by a sudden urge to kiss and lick along the pale skin, just under the Omega’s ear. He stepped back quickly, turning back to the meal prep he had been working on, trying to ignore the way his heart was hammering in his chest.

“This morning.”

Genos thought about it for a moment, “preheat symptoms typically start around forty eight to seventy two hours before the actual onset. We can go, but we should stay home after today.”

***

They arrived at the Fight-House, dressed in their fighting outfits, to find a line that stretched for half the block and a swarm of paparazzi at the front. Seeing the crowd, they understood why they had both received messages telling them to enter through the back door and go straight to the VIP area. Even though high ranking fighters had the option to skip the line, it was better to avoid the crowd entirely.

“Wow,” Saitama said as they got out of the car behind the building, “the guest fighter tonight must be a big deal. I hope he’s strong.”

Genos nodded in agreement, but an uneasy feeling was starting to settle in his gut. He wasn’t fond of crowded places in general, and now with his mate so close to going into heat, his instincts were insisting that he needed to bring his Omega home and protect him. He firmly reminded himself that his mate didn’t need protection, as a security guard discreetly led them through the back door.

After they made their way up the back steps to the VIP area, he noted with relief that there weren’t very many people up there. Looking down over the rest of the bar, he saw that it was absolutely packed. Not a single seat empty, and a fair amount of people standing as well. Hardly a square foot of space went unoccupied.

“I said no flash photography inside the building,” Fubuki was saying to one of the security guards as they approached, “make sure anyone caught doing it gets kicked out. If we get too many of them going off at once someone’s going to have a seizure. You know how much paperwork I would have to do if that happens?”

Satoru, and Sonic had already claimed a couple of chairs next to her, so they sat on the loveseat across from the table she had piled high with papers.

From the corner of his eye, Genos spotted a familiar shade of blue. On the other side of the VIP area, surrounded by women was Amai. He had to suppress the urge to growl like a feral animal. What was he doing there? The Alpha unconsciously clenched his hands, almost wishing his cousin would provoke him again, so he could have an excuse to punch him.

“So why’s this place so crazy tonight?” Saitama asked after they had exchanged their greetings.

She looked at them for a moment, eyes narrowed, as if trying to read something in their expressions. After a moment she replied “How out of the loop are you? You mean you don’t know?”

“A video of your fight on Monday went viral, all these assholes are here to see the Omega fighter and his sexy microwave.” Sonic explained, “don’t you check the forum?”

The mates glanced at each other and then shrugged.

“Anyway,” Fubuki moved on, “The fighter I scheduled, Stinger, had some kind of injury. His local Fight-House sent a last minute replacement. Tonight, you’ll be fighting Sea King.”

Chapter Text

Before the matches began, Saitama separated himself from the rest of the group to go hang out in Fubuki’s office claiming the noise from the crowd and fluorescent lighting was aggravating his headache.

“Are you sure?” Genos asked, while checking his pulse. “We can just go home if you need to.”

Yeah, it’s fine, the Omega replied. “I want to fight that Sea King guy before we head out.”

The blonde offered to stay with him in the office, but the bald man declined. “You should watch the matches, you might learn something. Don’t worry, it’s just a headache.”

After checking the Omega’s temperature with a hand on his forehead, the blonde reluctantly agreed. He didn’t really want to let Saitama out of his sight, but it was comforting to know that the bond would alert him if anything was wrong. He quickly glanced over to where his cousin appeared to be flirting with one of the waitresses, it was probably better if he stayed to keep an eye on the blue haired menace.

It wasn’t long before the announcer’s voice came on the loudspeakers, introducing the guest fighter. The Alpha known as Sea King, was enormous, like a mountain of rippling muscle. The kind of physique that required high doses of steroids, even for Alpha’s to achieve. Clearly the fighter was proud of his figure, because he was dressed in only a speedo, a crown, a cape, and heart shaped nipple pasties. He had used body paint to colour himself mostly green, with light blue on his face as well as his pecs and abs. The look was completed with purple lipstick and fin-like attachments over his ears.

Genos wrinkled his nose in distaste, the guy looked like some aquatic clown. Still, he wouldn’t underestimate his opponent this time. He had learned his lesson when he was battered by Mosquito Girl.

Similar to the week before, the guest fighter would go head to head with the local challengers, one at a time until they either won all their matches or were defeated. If they lost, the fighter who beat them would take their place. It was less common than tournaments, or a single match against a specific opponent, as it required a great deal of endurance and stamina. This Sea King must have been quite confident to have specifically requested it.

The blonde leaned on the railing that overlooked the ring, watching intently. Saitama had recommended he watch the fights in the hope of learning something, he might as well take his advice.

The first opponent, Puri Puri Prisoner, another large Alpha entered the ring, blowing kisses to the crowd. He wore a skin tight white and black striped outfit to match with his nickname. Just as Genos was starting to think it may actually be an interesting matchup to watch, the Alpha flexed his muscles hard enough that his outfit ripped off at the seams. The man wasn’t even wearing anything underneath, and was immediately disqualified for indecent exposure. Before security escorted him from the ring, the man looked up at where the blonde was watching him, blowing a kiss and winking. Genos scowled back in disgust.

As Sonic descended the stairs to enter the ring, Satoru joined the blonde, leaning against the railing. “I’m planning to propose,” the brunette said, “I’m going to ask him to mark me too… I know we won’t be bonded, but I still want him to.”

Seeing the brunette's wistful smile as he looked down at his boyfriend, it was all too obvious how much he loved his intended mate. “That little shit is going to be one hell of a bridezilla,” he replied. “I’m happy for you”

The Alphas returned their attention to the ring as the match began, watching as Sonic was immediately put on the defensive. His green painted opponent started with a quick and brutal series of punches, and the black haired Beta could do nothing but dodge. He was nimble, ducking, jumping, and rolling to evade.

Genos could see how the slim Beta was capable of taking down opponents that were much larger than himself. He used his speed and agility to outmaneuver and tire his opponents and attack their weak points. Unfortunately, in this particular match, his opponent wasn’t leaving any openings.

After a while, the larger combatant picked up speed, coming at the beta fast enough that he was forced to block more often than dodge. The Beta’s usual grin disappeared as he was forced to move closer to the edge of the ring. A large, green painted hand managed to grab onto him by the collar of his body suit. Believing his opponent to be immobilized Sea King pulled his free hand back preparing to land a heavy blow.

Sonic pulled away hard enough to tear the front of his suit, exposing his chest. Ducking under the incoming punch, he moved back to the very edge. The Beta was breathing hard, eyes narrowed in a calculating expression. As the Alpha moved to close the distance between them again, he hopped backward out of the ring, bringing their match to an end.

As the Beta rejoined them in the VIP area, he was already starting to catch his breath, but Genos could see the sweat on his brow, and how his left arm hung limp at his side. Clearly blocking those attacks had come at a cost.

“Both of you should forfeit,” he said bluntly, then pointed an accusatory finger at Satoru, “especially you. You’ll get hurt because unlike me, you don’t know when to stop.”

“No can do,” the brunette replied, “I got a sponsor for this one, the longer the match lasts, the more they’ll donate to the children’s hospital.” The fact that the deal didn’t even take into account the possibility that he might win spoke volumes. He glanced at Genos before adding “they have a really good pediatric burn ward.”

Sonic glared at him for a moment, before his expression softened. “You’re an idiot,” he said, then rounded on Genos. “I know you’re best friends, but don’t be like him, we can’t handle more than one of him.”

Muttering about idiots who want to play at being heroes, the Beta walked away to go get himself a drink and find something to wear over his damaged bodysuit. With a shrug and a sheepish smile, Satoru went trailing after him.

Chapter Text

The Sea King’s next three matches went quickly. Genos wasn’t sure if he learned much from them, other than that the fighter had a lot of stamina, and seemed to take joy in hurting his opponents. The blonde’s brow creased with worry at the thought.

He would be fighting in the next match, and if he lost, the next to fight the Sea King would be Satoru, followed by Saitama. He could reign in his protective instincts by reminding himself that the Omega was stronger than he was, but he was still concerned. His mate’s headache had been bad enough that he had to go lie down, would he really be in any shape to fight?

He was more worried about Satoru, the other Alpha seemed to have no sense of self-preservation, especially when he was helping others. They had met because the brunette had a special talent for getting himself hurt. He could still remember meeting the other alpha when they were only twelve, after he had gotten himself paralyzed by jumping in front of a speeding car to push a baby in a stroller to safety. Lacking other options, his family had signed him up to be the test subject for Dr. Kuseno’s artificial spinal cord.

It would be better if Genos could win his match. He wouldn’t insult his friend by taking it easy on him, but he was fairly certain he could throw him from the ring without doing too much damage. If he lost, and Satoru fought Sea King, there was a chance the brunette would find himself back on Dr. Kuseno’s operating table.

“Genos,” his cousin greeted while moving to lean against the railing next to him, “you and that mate of yours have certainly been busy making a spectacle of yourselves this past week, haven’t you?”

The blonde resisted the urge to growl, and shifted not so subtly to put more space between them.

“Usually I’d assume newlyweds would find it too difficult to keep their hands off each other to be out starting scandals but…” The blue-haired idol’s gaze quickly flicked down to the blonde’s chest before looking back up at his eyes, “I suppose neither of you is terribly attractive.”

“Saitama’s very attractive,” he replied, subconsciously clenching his fists by his sides. He was tempted to punch his cousin again, but he didn’t want to risk getting disqualified before his fight. The idol’s burst of laughter in response sorely tested his self-control.

Genos sighed and leaned against the rail, keeping his eyes on the fight below. “What are you after? If you’re looking for a fight you’ll have to challenge me another time.”

“I wouldn’t fight in a place like this, I have standards,” Amai responded, “I came over here for the view. The next few matches will be very interesting.”

Before the blonde could think of a retort, Sea King’s opponent cried out that he gave up, ending the fight. With one last glare at his cousin, Genos made his way to the ring.

While from a safe distance Sea King looked ridiculous, up close with him towering over a foot taller than Genos, and the scent of aggression filling the air around him, the green-painted Alpha was an intimidating presence. The blonde’s instincts were practically screaming in alarm, demanding he win the fight to protect his mate, his friend, his -pack.-

That was… interesting. Did he consider Satoru to be part of his pack? Alphas rarely saw each other that way unless they were related, but Satoru was practically a brother to him anyway. Shit that meant Sonic too, probably. He’d have to think about this later when he had more time.

Genos took a deep breath, shifted into a ready stance, and lept into action the moment the announcer called out “ready… fight!”

Hoping to take advantage of the fact that he was rested while his opponent had been fighting for some time, the blonde moved quickly attempting take control of the match by landing the first few hits. Sea King was faster than he anticipated, not seeming fatigued at all. The larger alpha blocked each punch, before attempting to land one of his own.

Genos jumped back out of reach, realizing that tactic wasn’t going to work. Just like Sonic’s match earlier, speed alone wasn’t enough to beat him. He didn’t have the advantage of size and strength to overpower his opponent either.

Before he had the time to come up with a better strategy, the gap between them was closed. Genos ducked under an incoming punch and aimed a kick at the other Alpha’s knee. A large hand grabbed onto his ankle. The blonde didn’t have any time to react before he was swung forward, onto the ground in front of his opponent.

Dazed slightly from landing heavily on his back, Genos attempted to kick back at his opponent with his free leg. Sea King simply stomped on the side of his ankle with a heel, then ground down into it. There was a crunching sound, and then the blonde lost feeling in that foot.

Cursing under his breath Genos rolled to free the leg that was still in the larger Alpha’s grasp. Down a foot, he wasn’t going to be able to use his usual fighting style, he would have to find a way to bring his opponent down to his level. If he could get him pinned, he would be able to negate his disadvantage.

The blonde managed to get himself up on one knee, before another punch was aimed at his face. Hoping to take advantage of his lowered centre of gravity and his opponent’s momentum, he grabbed onto the other Alpha’s wrist pulling it down and to the side.

Cold dread washed over him when Sea King didn’t budge. A kick to the stomach laid him out flat on his back, too winded to do anything when a foot stomped down on his bicep, pinning his arm. Sea King reached down, grabbing onto his forearm, and with a hard twist, snapped the prosthetic off at the elbow.

Mosquito Girl had done a lot of damage to his limbs when she realized they were prosthetics, but she had mostly just repeatedly hit the joints. This was different, more deliberate, the larger Alpha knew how to take advantage of his weak points.

Genos looked up to where Amai was leaning over the railing, the idol was clearly delighted. With a grin his cousin raised his drink in a mocking toast. That prick, that’s why he was there, to watch Sea King break him apart like a child’s toy.

The blond was filled with rage, his instincts screamed for him to keep fighting, but he knew he no longer stood a chance. The only thing he could do now would be to end the match, and avoid giving his cousin any more satisfaction.

As if the larger Alpha had read his mind, he stomped a heel down into the blonde’s stomach, forcing the air out of his lungs before he could say a word. Sooner than he could draw another proper breath, Sea King was at his other side, stomping on his remaining arm. With a twist, a crunch, and a brief flash of pain as artificial neurons were pulled apart, that one was gone too.

Seemingly satisfied with the damage, Sea King lifted the blonde like a sack of potatoes, and tossed him unceremoniously out of the ring. For a moment, the crowd was oddly silent, until Genos sat up, then excited chatter was all around him, microphones and cameras shoved in his face as he was asked far too many questions to answer all at once.

He glared back at them, some backing down under the intense black and gold gaze, until a few security guards came to help him. Two of the large Alpha’s supported his weight under each arm, while the third trailed behind, carrying his forearms.

Once they reached the bottom of the steps, an area security kept clear, Satoru brought him a chair. Even with help, he was too exhausted to climb the stairs with only one good leg. Sonic, now wearing an overlarge green hoodie that he had presumably borrowed from the brunette, took his arms from the security guard. Once Genos was seated the Beta set them down next to him. The desire to say “I told you so,” was clearly written all over Sonic’s face, but to his credit, he managed to resist.

Genos looked up to where Amai was still leaning against the railing, wishing he could smack the smirk off the idol’s face. Why was he still positioned to watch the next match, didn’t he already get what he wanted?

A surge of panic rose up in him as he recalled what his cousin had said, “The next few matches will be very interesting.”

“Satoru,” he said, “Sonic was right. You need to forfeit. Whatever your sponsor would donate, I’ll triple it. Don’t fight him.”

***

On the sofa of Fubuki’s office, an unconscious Saitama stirred restlessly.

He had intended to watch the matches from the large screen TV that hung on her wall, or at least pay enough attention to know when it was his turn. He had actually been interested in Sonic’s match, thinking the Beta did seem quite flashy and cool as he rolled and jumped to dodge Sea King’s attacks.

His headache had been getting worse, pounding at his temples in time with his pulse, getting faster, leaving him light-headed. He had been debating if they should leave after all, when darkness had crept into the edges of his vision. With a sensation like falling backwards into the void, the Omega had passed out.

Distantly, part of him was starting to regain awareness, as if pulled by the bond signaling his mate’s rapidly increasing distress.

Chapter Text

“You know I never back down from a fight Genos,” Satoru replied. The brunette’s usual friendly demeanor was replaced with a dark expression, the scent of aggravated Alpha practically rolling off him in waves. It probably wouldn't have convinced him anyway, but now the other Alpha was clearly itching for a fight. There was something borderline feral in his eyes as he turned to take his position in the ring.

The crowded bar erupted into cheers as the brunette shifted into his fighting stance, knees bent, fists at the ready in front of him. Genos raged internally at his own inability to stop whatever would be coming next. Satoru looked so small with the green Alpha towering over him.

“Shitty ranking system,” Sonic complained, “popularity counts for too much of the score. Of course he’s popular, just look at that precious face. He’s always getting matched up against opponents he’s got no business fighting.” The Beta sat on the ground next to the chair, and wrapped his arms around his knees, curling in on himself. “I don’t want to watch this,” he grumbled, “I hate it.”

Genos couldn’t think of a reply, he wanted to say something optimistic, but before he could come up with anything, the match began. They watched as Satoru surged forward, only to have his first punch easily blocked by the larger Alpha’s open palm. Before they even registered what had happened, Sea King grabbed onto the brunette’s wrist, and pulled, swinging him in an arch to crash down onto the ground.

***

Saitama snapped awake, the feeling of helpless fear coming through the bond pumping enough adrenaline though his system to finally shake off whatever it was that had made him pass out. Bright spots of light flashed in his vision and he staggered back, almost falling over, from standing up too quickly. Were pre-heat symptoms normally this severe? Whatever, he could worry about it after he checked on Genos.

With his heart pounding so hard in his chest it felt like it would burst, the Omega rushed down the hall to the door that would bring him closest to the ring. As he emerged, not far from the stairs to the VIP area, he saw his mate. He noted with alarm that the Alpha’s arms were snapped off at the elbow, and one ankle twisted at an unnatural angle.

The blonde, however, seemed to have little concern for his damaged prosthetics, his golden eyes were fixed on the ring, his expression grim. Turning to look at the match, Saitama understood the reason for his distress. Mumen Rider’s matches were hard to stomach at the best of times, but this was brutal.

The brunette was being mercilessly pummeled. Though he had a reputation for not giving up, it looked like the larger Alpha was making sure not to give him the opportunity. A series of kicks and punches to his core were keeping him too winded to speak, and he was held up by a firm grip on the front of his clothes, preventing him from reaching the ground to tap out.

The Omega felt guilt gnawing at his insides, he felt like he had arrived too late. Maybe if he had been paying attention he could have convinced Fubuki to change the order, if he had fought Sea King before they did, this wouldn’t have happened.

Just as he decided to interfere with the match, the large green-painted Alpha lifted the brunette and flung him from the ring. Saitama rushed forward, arms extended, catching the other man before he could land on his head.

“Good job,” the Omega said, hoping he sounded encouraging, “nice fight.” He helped the Alpha to where the others were seated.

Sonic immediately pulled the brunette into a tight embrace before looking him over to assess his injuries. “Why do you Alpha’s always have to be so stupid?” he muttered, as he helped the brunette sit leaning against the wall, “why do you always have to scare the shit out of me?”

With Mumen taken care of, Saitama turned his attention back to his mate. “Hey Genos,” he said, “are you alright?” The blonde nodded, but his pained expression said otherwise.

Saitama felt his anxiety shifting to rage. Sea King had gone way too far. The Omega knew what it was like to fight against weaker opponents, it wasn’t that hard to force them from the ring without breaking them. This was just unnecessary, and judging by the grin on the large Alpha’s face, he had hurt them just for the fun of it.

“Hang on a second,” the Omega said, “I’m gonna go beat this sea freak.” Before the blonde could protest, he rushed over to the ring, jumping up to get into position for the fight.

As the announcer called for the start of the match, blackness crept in around the edges of the Omega’s vision. Just as the worry that he might pass out again began to cross his mind, a punch to the head shocked him back to his senses.

Sea King started to say something about Omegas being weak and Alpha’s being superior, clearly feeling confident enough to talk instead of pressing the advantage of getting the first strike. Not interested in what he had to say, Saitama put all of his strength into an uppercut to the Alpha’s diaphragm.

The large Alpha toppled over, collapsing onto the ground to curl up around his midsection, and didn’t make any move to get back up. It looked like he was in too much pain to say anything or tap out, so Saitama kicked him over the edge of the ring, not bothering to be gentle about it.

The crowd erupted into chaos. Saitama struggled to keep track of their mixed reactions as he fought to keep his breathing under control. Was it hot in there, or was it just him? Were his hands shaking?

Someone yelled out “maybe Sea King wasn’t that strong after all, an Omega beat him with one punch,” another yelled “Z-Citys fighters are all wimps.” Just like that, somehow the audience was swayed, other voices joining in to yell out that the other fighters were pathetic, pointing out that none of them had been able to beat the Omega in the last three years.

Saitama sighed, if the other fighters' popularity dipped too low, they’d start missing out on sponsorships and other opportunities. He didn’t want his chronically bad reputation to end up dragging the others down with him. He decided the best thing to do would be to once again play into his role as a heel. If he claimed he fights last so that the others can weaken his opponents first, he could probably make it look like he was artificially inflating his ranking. Maybe then the public’s scrutiny would be focused back on him.

Just as he opened his mouth to say something, he felt a sudden wetness. His eyes widened in alarm and his mouth snapped shut. The others would have to worry about their own reputations after all, he had a much more urgent problem.

He jumped down from the ring, and rushed over to the stairs, pushing past the people that were trying to gather around him. Some looked offended for a moment, before they gave him shocked looks and cleared the way. Shit, he hadn’t been bothering to use scent blockers. Even if being bonded meant his scent wouldn’t draw in other Alphas, everyone around him could still tell he was about to go into heat.

“I’ll be right back,” he said as he rushed past Genos, taking the steps three at a time in his haste. There were so many cameras there that night, if he didn’t get out of there before the slick soaked through his clothing he would never hear the end of it.

“We need a ride home, right now,” he panted when he reached Fubuki, “make sure the driver’s a Beta.”

Her expression quickly shifted from puzzled to concerned when she picked up on his scent. “I’m on it, someone will meet you at the back.”

The Omega called out a quick “thanks,” as he hurried away.

When he reached his mate he grabbed the Alpha and threw him over a shoulder, picking up his broken off prosthetics with his free hand. “Sorry, I’d normally find a more dignified way to do this, but we don’t have any time” he apologized, before rushing, practically sprinting through the door Sonic already held open for them.

As he hurried towards the exit, he asked “so, how quickly do you think your dad can fix your arms?”

Chapter Text

Genos stared at the ring in absolute bewilderment, mirroring his shock from the week before. Every time he saw Saitama demonstrate his strength it pushed the boundaries of what he believed to be possible, not just for an Omega, but for anyone.

He had been so shocked by his mate’s sudden appearance, and so stressed, that he hadn’t managed to put together the words to beg Saitama not to get into the ring with Sea King. As he watched the large Alpha’s crumpled form getting booted from the ring as casually as one would kick a soccer ball, he was relieved he hadn’t said anything. He felt a slight pang of shame that he had underestimated his mate.

Once his fear for his mate dissipated, he turned his attention back to his injured friend. “Are you alright Satoru?” Still winded, the other Alpha gave him a weak smile, made crooked by the swelling on one side of his face, and a shaky thumbs up.

“I’m going to take him to the hospital,” Sonic interjected, "I'm pretty sure a couple ribs are broken.” The brunette’s expression shifted to a pout. “Don’t you give me the puppy dog eyes,” the beta glared at him, “you’re getting medical attention, and then you’re going to rest until you’re recovered. None of this pretending you’ll rest then doing charity work instead bullshit, either. I’m staying at your place until you’re better.”

“If there’s anything the hospital can’t help with, or his condition gets worse, call my dad,” The blonde said before his attention was pulled back to the ring. The crowd had gone from a mix of surprise and a few cheers, to hurling insults at all of the fighters of Z-City. Saitama’s expression had shifted to something that reminded Genos of how he had addressed the audience after his previous fight.

Was he once again going to be the heel? It didn’t quite sit right with him, knowing that Saitama had just done something amazing, but the spectators were downplaying his achievement because of his presentation.

The Omega seemed like he was about to say something, then froze, eyes wide. Without a word he dashed from the ring and rushed to the stairs, pushing past anyone that tried to talk to him. “I’ll be right back,” his mate said as he blew past. The sweet scent that trailed in the air behind him revealed the reason for his sudden urgency. He was going into heat!

That made the fight he had just witnessed all the more impressive, an Omega on the cusp of their heat was usually light-headed and weak. If that’s how strong he was in a weakened state, what was he capable of at full strength?

When his mate returned, and easily threw the Alpha over a shoulder in order to carry him out, Genos was impressed all over again. He apparently -really- liked it when Saitama manhandled him. He tried to take a deep breath to keep himself calm, but it had the opposite effect. Up close, the sweet, almost molasses-like scent of Saitama’s pheromones, smelled better than he could possibly have imagined.

As he rushed toward the exit, the Omega asked, “so, how quickly do you think your dad can fix your arms?”

Shit. That was a good question. Genos looked down at his broken prosthetics with a sigh. For the second week in a row he was returning home in need of urgent repairs.This time, the arms at least, were snapped off fairly cleanly at the joints. It wouldn’t take as long as before thankfully, but Dr. Kuseno would need to rush in order to finish before the first wave Saitama’s heat reached its peak. After some consideration, he replied, “probably a few hours.”

“Ah fuck. Ok,” Saitama replied, skidding to a stop as they reached the exit. One of the guards hastily pulled the door open for them, revealing that a sporty looking black car was already waiting for them, with the windows all rolled down.

A short female Beta that Genos recognized as one of the servers hopped out and opened the back door for them so Saitama could get the blonde settled in. “Here,” she said, handing the Omega a towel before he got in. The bald man simply nodded, his face red. He tossed the towel on the leather seat before he sat down. Once she had returned to the driver’s seat the Beta called back to them, “buckle up!” After the bald man ensured they both had their seatbelts on, she hit the gas and they peeled out of the parking lot at a borderline alarming speed.

“That was close,” Saitama said as he leaned to rest on the Alpha’s shoulder. “Slicking through your clothes in public is like what would happen if peeing your pants and getting a badly timed boner had a humiliating love child.”

The Alpha had no idea how to respond to that, and not wanting to blurt out something stupid opted to say nothing. Saitama was already leaking slick? He hadn’t bothered to think about it much, outside of general medical knowledge, because he’d never met an Omega that he was attracted to before. The thought of his mate dripping with slick however… that and the scent of the Omega’s pheromones were filling Genos with a primal desire. The same traitorous hormones that he had been wrestling with all week, were now refusing to be ignored.

Saitama sniffed at the air for a moment before turning to look at him, “ah Genos, are you…?”

The blonde jerked away from the other man, pressing himself up against the car door. He’d gotten so worked up that even with the windows down the Omega’s sensitive nose picked up on his arousal. “Sorry, I-”

“It's fine, we're bonded mates," the bald man cut him off, “It’d be kinda mortifying if you weren’t.”

***

When they arrived, Dr. Kuseno was standing outside with a wheelchair at the ready. As Saitama helped his mate out of the car, the old man said “Your friend called. He said my idiot tin can almost got himself recycled at a very inconvenient time.” Genos scowled, certain the caller had been Sonic. Even when he was being helpful, he always had to be an ass. Still, the blonde didn’t dislike him quite as much as he used to.

“After your last fight, I thought it might be wise to spend the week preparing a second set of prosthetics,” the old man continued, “It seems my intuition has been quite good lately.”

With Saitama pushing the wheelchair, the old man directed him to the correct examination table. “You can go rest for now,” he said to the Omega, “There’s no damage at the ports, so I should have Genos right as rain in about thirty minutes.” The Beta gave them an assessing look, taking in their flushed faces, then said, “hmmm… better see if I can make it fifteen.”

***

Once the damaged limbs were replaced Genos made his way to the living quarters to find his mate. He looked in Saitama's room first, to find that the Omega wasn’t there, and the blanket and pillows had been stripped from the bed.

In his own room, he found his mate on his bed, having changed into his blue striped pajama pants. The bald man had apparently brought every pillow and blanket he could find and arranged them around the outer edge of the bed. The Omega was resting, curled up on his side, and clinging to a pillow that the blonde suspected was the one he usually slept on.

He hadn’t expected Saitama to have much of a nesting instinct, but the other man had never had a proper heat before, so there wasn’t really any way they could have known. Something about it filled Genos with warmth, and his instincts were practically singing their approval. His Omega had chosen to make a nest in his room. That meant at the very least, his mate was comfortable with him.

“Saitama,” he greeted, “Are you?…”

“Yeah, I’m still all there,” the other man replied, rolling over to look at him.

That was good, it made this conversation a little easier. “There are some Omegan birth control pills on my dresser, you should probably take one now… unless you’re already wanting to start a family.”

The already flushed Omega turned bright red. “Right… I figured we would eventually, but right now… I’m not ready for that,” he replied, rubbing the back of his neck nervously. With a nod the blonde moved to his dresser to pop one of the pills free of the bubble pack, and then grabbed one of the bottles of water he had already stocked in a corner of the room, before passing both to his mate.

As Saitama took the medication, the Alpha asked, “is there anything else I can get for you, or do you just want me to give you some space until the first wave hits its peak?”

“You can stay if you want,” the bald man replied, reaching out to take the Alpha’s hand, “I’d like it if you would lie down with me… if it doesn’t bother you.”

“Of course,” Genos said as he joined his mate in the hastily constructed nest. “It doesn’t bother me at all. I'd be happy to stay with you, for as long as you want.”

Chapter Text

Saitama could hardly believe his ears when his mate agreed to stay with him. An Omega in heat inviting an Alpha into their nest was about as blatant of a proposition as he could have made, just short of just outright asking for it. Judging by the blush spreading across the blonde’s face, and the all too enticing scent of arousal that was starting to build in the air around him, he knew exactly what was implied when he accepted.

As bonded mates, it was necessary for them to come together when the waves of the Omega’s heat reached their peak, and the Alpha would be triggered to rut, but this was different. This was something much more intimate. Genos had agreed to join him while they were both still fully in control of themselves.

He probably wouldn’t have had the courage to ask, if it weren’t for something that he had realized when they were on the way back. He had originally thought that the Alpha hadn’t been attracted to him at all. Considering he hadn’t made any move to consummate their marriage it seemed like a reasonable assumption. When he noticed that the other man’s scent had changed, he thought that maybe the attraction was there, but Genos had been holding back. The blonde’s flustered response when he tried to ask about it, confirmed his suspicion.

Even after being invited into the nest, the Alpha had made no move beyond resting his head on the Omega’s shoulder. When he thought about it, Genos had seemed reluctant to initiate physical contact, but always enthusiastically accepted anything that Saitama offered. Looking back at the last week they had spent together, his mate’s actions didn’t seem disinterested anymore, but more like he was nervous.

“Hey Genos,” he started, “you know I’m a virgin, with the white robe at the auction and all, but to be honest, I haven’t done -any- of this before. Our wedding was the first time I’ve even kissed anyone. How much… um… experience do you have?”

“None,” the Alpha replied, “at least, no more than you have.”

Ah. That explained a lot. Neither of them had any idea what they were doing. It was becoming clear to Saitama that if he wanted anything to happen while he was still lucid, he would have to take the initiative. He adjusted their positions so that the Alpha was on his back, propping himself up on his arm next to him. He cupped his mate’s cheek with his free hand, turning his face so that he could look directly into those golden eyes. “Genos,” he asked, “can I kiss you?”

“You can do anything you want to me,” the blond replied softly. The expression on his face was the same as it had been when Saitama had pinned him at the gym. Christ, the Omega had a very physical reaction to that, heat pooling low in his gut, and his member throbbing where it was already straining against his pajama bottoms.

The bald man chuckled nervously then swallowed hard. He leaned in, brushing their lips together softly at first before deepening the kiss. The blonde kissed him back eagerly, moaning softly against his lips. After a while, the Omega tried using his tongue, and then it was his turn to moan when his mate did the same.

When he had to pull back for a moment to catch his breath Saitama said, “I don’t think you realize what kind of things I want to do to you.” Cautiously, testing to see where the Alpha’s boundaries really were, he moved his hand from his cheek to the back of his mate’s head, gently gripping a handful of his blonde hair. He carefully tugged downward, tilting his mate’s head to get him to bare his throat.

The Alpha made no attempt to resist, eyelids fluttering shut, offering his submission to his mate as if it were completely natural to him. Somewhere in the back of Saitama’s mind, part of him insisted the Omega was the one who should be submitting right now, but he was far too captivated to pay it any attention.

He placed a few kisses along the now mostly healed bite at the base of the Alpha’s neck. His mate had gone through so much to clear away the scars on his face and neck, but he had let Saitama mark him there. Then he nipped, kissed, and gently dragged his teeth across his mate’s throat. The Alpha gasped, and whimpered, and it sounded even better than he had imagined it would. God, Genos really did trust him, didn’t he?

Just how much was his mate really willing to let him get away with? How far could he stray outside the boundaries of what an Alpha would normally accept? He moved his hand back to his mate’s cheek, rubbing the pad of his thumb over his bottom lip. The Omega drew a shaky breath, before asking something that would probably start a brawl with most Alphas. “What if I wanted to fuck that pretty mouth of yours?”

The blonde’s breath hitched, golden eyes opened in surprise, but he didn’t pull away. “I’d… I’d like that,” he replied, “I’d like it a lot.”

As if to reward him, the Omega leaned forward again, capturing those soft lips in another deep kiss. They had hardly done anything, and he was already breathing hard, practically panting. He was nearly painfully aroused, leaking slick to the point that he was sure his pants had already soaked through. By the way his mate moaned and whimpered against him, it was clear the feeling was mutual. His Alpha was turned on from getting dominated, it was intoxicating.

He was starting to realize that Genos had really meant that he could do -anything.- He ran his hand down his mate’s chest, and stomach, stopping when he reached the edge of his jeans. He dipped his fingers just under the edge of close fitting denim to brush them against the blonde’s hip, before reaching around behind to touch just above his tailbone. “What if I wanted to fuck you down here?”

The high pitched, needy whine he got in response told the Omega in no uncertain terms that Genos would like that too. “If you’re this… ah… interested, why didn’t you say anything?”

The blonde ran a hand across his chest, something Saitama had realized he did subconsciously when he was thinking about his scars. “I didn’t want to pressure you,” he replied, “You didn’t get any say in who you married, and I didn’t think you’d want… Someone like me… I’m… broken, I’m hardly human any-.”

His words were cut off as the Omega surged forward to kiss him again. Saitama felt like his heart was aching. Of course, he should have known how self-conscious Genos was. He remembered the way he had looked on their wedding night, the fear of rejection that was written all over his face.

“Genos,” he said as he moved to position himself between the Alpha’s legs, “You’re gorgeous.” He slid a hand under the Alpha’s shirt, tracing his fingers along the scars that he could feel across his stomach. “I’ve wanted to have you like this since the moment you offered to let me bite your neck.” He pulled at his mate’s shirt, directing him to take it off. Once the offending article was gone, he let his hands roam across the exposed skin.

The blonde whimpered, arching his back into the touch. The Omega groaned when the shift in position caused their erections to rub against each other through their pants. He rocked his hips against his mate, chasing more of that friction, and was rewarded with a series of moans from the Alpha.

The bulge pressing against him from inside the jeans was huge. He reached down to trace the shape of it with his hand over the denim. “How… ah… how big exactly?”

“Eight-and-a-half inches,” The blonde breathlessly replied between the whimpers and moans Saitama was wringing from him.

The Omega swallowed hard. “I know Alphas are usually pretty big… hah… but fuck that’s huge.” He undid the button, glancing at his mate’s face to make sure he was still alright with it, before pulling down the zipper. He pulled down the pants and boxers together, savoring the view as the rest of his mate was revealed.

Saitama leaned back, taking a moment to just take in the sight of his Alpha, flat on his back and naked in front of him for the first time. Blond hair was tousled, scars covering nearly every square inch of skin that stood out in contrast to the smooth inky black synthetic skin of the prosthetics, and those golden eyes filled with lust. “Fuck you’re beautiful,” the Omega breathed, before bending down to kiss and nip at the textured skin along his mate’s hip.

“Can you… ah mmm… Can you take yours off too?”

The Omega hesitated for a moment. He could pass for an Alpha when he was dressed, but he wasn’t exactly endowed like one. His five-and-a-half inches in length was large for an Omega, average for a Beta even… but then there was the slick, a lot of it… He took a deep breath to steady himself. “Sure.”

He pulled off his pants and boxers before tossing them out of the nest, cringing a bit at the wet sound they made when they hit the floor. When he looked back to Genos, his momentary nervousness melted away, his mate was looking at him like he was something to be devoured.

The Omega trailed kisses and bites as he moved upwards along his mate's body, so that he could reach those soft lips again. The Alpha wrapped his arms around him, pulling him down to rest his weight fully against him. The Omega moaned at the delicious feeling of skin on skin, rocking his hips experimentally to grind his erection against his mate’s. He reached down, taking them both in one hand (though the two of them together was a bit too big around for him to get a decent grip), and began to stroke them in time with their kisses.

It felt so good, he could have been happy to just make out and grind against each other all night, but then his biology reminded him that he didn’t have that luxury. An intense cramp rolled through his lower abdomen like a wave, leaving a burning feeling of need in its wake, and the slick that was already dripping from him before, started to trickle down his thighs. He stopped for a moment, resting his head against the blonde’s shoulder, letting out a pained groan.

He felt the Alpha tense beneath him, “Are you alright?”

“I’m fine, it’s jus-” his words were cut off when another cramp hit, worse than the first one, like he had been stabbed with a blunt object just beneath his navel. “Ffuuuck,” he hissed out.

Genos carefully rolled them so that the Omega was on his side on the bed. Saitama grimaced, the room was spinning, he felt like he was floating, and it was getting harder to think beyond the aching need building up inside of him.

“Your pupils are completely dilated,” the Alpha said.

They were out of time.

Chapter Text

Genos hadn’t been quite sure how his mate would behave once his heat reached his peak. For some reason, he hadn’t really been able to picture Saitama face down in the mattress, hips in the air, presenting and begging for an Alpha to mount him.

Well, the bald man was on his knees alright. He was straddling the Alpha’s waist, pinning his two wrists above his head with one hand. His other hand gripping a fistful of blonde hair, pulling the Alpha’s head back to make him bare his throat.

A shiver ran down the blonde’s spine in response to the feeling of teeth against his neck. The Omega was being rougher with him than he had been earlier, it was just bordering on painful.

Distantly, a part of him wondered if he should be alarmed by how much he liked it, and how quick he had been to offer complete submission to his Omega. He was certainly learning a lot about himself that night. After the sexual fantasies he’d had about his mate, he’d been worried he might be a pervert, now he knew for sure that he was.

The scent of Omega pheromones pervaded the air, so intensely the Alpha could nearly taste it. He was certain that if he were to look in a mirror, there would only be the tiniest sliver of gold still visible against the black of his eyes.

Thankfully an Alpha’s rut was not quite as all consuming as an Omega’s heat, allowing them to remain more alert in order to protect and provide for their mate. He was able to keep a tenuous grasp on his self-control, though it took every ounce of his will power to do so.

“S-Saitama,” he managed to say between the moans and gasps the rough treatment was pulling from him, “I’m, ah, I’m going to give you what you need, but… mmm… need… hah, need to stretch you out first, ok? You said it yourself that it’s huge. Don’t want, nnn ah… don’t want to hurt you...Please?”

The Omega paused for a moment, before letting go of his wrists, and capturing his lips in a searing kiss.

His hands quickly found their way to his mate’s thighs, before roaming up along his hips, admiring the smoothness of the pale skin marked only by the Alpha’s bite at his neck, and the firmness of the muscles underneath.

The Omega tensed for a moment, letting out a low whine, as another cramp hit, then growled impatiently in the blonde’s ear.

Genos moved a hand to grab the Omega’s ass, earning a moan and another impatient growl in response. He brushed a finger gently against his mate's opening for a moment, marveling at the wet glide of the slick, before slowly inserting it.

He began gently thrusting it back and forth, reaching deeper each time, until it was all the way in. The almost obscene moans his mate made in response was probably the most satisfying thing he had ever heard.

“Ah.. mmmm… hah… need more… aahhh Genos.”

As he began gently working in a second finger, the Omega’s hands found their way to his shoulders, gripping onto him so tightly the Alpha was almost certain it would leave bruises. It didn’t even register as pain, instead it was like a jolt of pleasure that went straight to his groin.

Even in the throws of his heat, Saitama’s strength was overwhelming. It was exhilarating, knowing that he was only able to touch him because his mate allowed it.

“Nnnn, ahh… it's not enough…hah, add another.”

He did as he was told, adding in a third finger and relishing in the sounds the Omega made as he carefully worked him open. Beneath the burning feeling of need that was building up in him, the Alpha couldn’t help but take a moment to appreciate how -good- it felt to feel like his mate wanted him.

The sight of Saitama practically writhing with pleasure and need was certainly something to behold. He had such smooth pale skin, with the defined muscle of a marble statue had come to life, and flushed pink from the tips of his ears down to his chest. The Alpha was still practically reeling from the fact that someone this perfect had called -him- beautiful.

It wasn’t long before the Omega caught his wrist, and moved his hand back to his hip instead. It seemed his patience had worn out.

Saitama adjusted his position to line them up, and slowly lowered himself, growling deeply as the tip breached his entrance. It took every ounce of the Alpha’s willpower to hold still, his instincts practically screamed at him to thrust upward and bury himself in the tight, wet, heat of his mate.

It seemed that the Omega’s instincts were making similar demands, because after a brief pause to adjust to the stretch, he pushed himself down until Genos was fully sheathed inside of him.

Like a rubber band that had been stretched too far, the Alpha’s grip on his self-control snapped. All coherent thought was gone, as they thrust against each other fast and hard. They were reduced to animals that knew nothing beyond the desire to take pleasure in each other’s bodies.

The Alpha felt teeth bury themselves into the meat of his shoulder as his mate’s channel convulsed around him, and more wetness joined the slick that already coated his stomach as the Omega came.

It was only a few more thrusts before he found himself instinctually burying himself to the hilt inside his mate, using his grip on the Omega's hips to keep them locked together, as his orgasm overtook him.

As Saitama collapsed from exhaustion on top of him and the pheromones in the air lessened, he felt his mind clear a bit. The first wave of the Omega’s heat had passed.

He knew he needed to get them cleaned up, as well as make sure his mate is fed and hydrated before the next peak came, but the Alpha wasn’t yet ready to get up. He took a moment to just cling to the Omega as he caught his breath.

Saitama placed a kiss over the mating bite on the Alpha’s neck, a surprisingly tender gesture after how rough he had been just moments before. The Omega sleepily mumbled something, the only word of which the blonde understood was “mine.”

“That’s right,” Genos replied breathlessly, “I’m yours.”

Chapter Text

As he slowly regained consciousness, the first thing the 14 year old boy (well Omega now apparently) noticed was the sound of his mom wailing like a banshee. It was muffled, as if his ears were stuffed with cotton, or he was somehow listening to her underwater. She was always such a drama queen, what was it now? The sound was grating, his head was pounding and he wished she would just be quiet for a minute.

Squinting against the bright fluorescent lighting that certainly wasn’t making his headache feel any better, he found himself looking up at an unfamiliar ceiling. Where was he?

He attempted to move a hand to shield his eyes a bit until they could adjust to the light, only to realize it wouldn’t budge. Alarmed now, he tried to move his other limbs, only to find they were similarly restrained. He turned to look at his arm, his stomach lurching as the movement caused him to feel like the room was spinning. He saw that he was bound to a gurney with leather restraints, and… what the hell was on his face? A wire muzzle? Why the hell was he muzzled like some violent criminal?

What the hell was going on?. The last thing he remembered was trying to get his mom to leave him the hell alone so he could suffer through the indignity of the beginning of his first heat in peace. 

He had suddenly started feeling sick at school, but tried to ignore it, thinking he could tough it out until it was time to go home. Well clearly he had been wrong about that, because it wasn’t even lunch time before he experienced the ultimate humiliation of slicking through his pants in class. It had been a mortifying way to find out that he was an Omega. He had just wanted to crawl in a hole and die.

His mother of course, completely ignored how he felt and was trampling all over his boundaries. The entire drive home she was talking about how they would redecorate his room, and how he should grow out his hair and start wearing dresses. He wanted to yell at her that presenting as an Omega hadn’t magically turned him into the daughter she always wanted, but he was pretty sure she would just think he was being hormonal.

Now he was apparently in a hospital, resisting the urge to puke (he really didn’t want to get sick while trapped on his back like that). He turned in the direction of his mother’s voice. She was standing next to his father, who seemed to have gotten his butt kicked at some point. The surly Beta was sporting a black eye, and was standing hunched as if his midsection hurt. Good, Saitama would have to give a high-five to whoever did it. 

They were talking to a doctor (a female Beta, he was surprised to realize he could tell just by the way she smelled) that was standing next to the gurney that the Omega was strapped to, her back to him. It seemed like they hadn’t realized he was awake just yet. He couldn’t quite make out what they were saying. He could hear them, but he couldn’t comprehend their words, they may as well have been speaking another language. 

What he could understand was the word written in bold red letters at the top of his chart on the doctor’s clipboard. A word he had only seen used to refer to animals, or when Alphas completely lost their shit and wound up on the evening news: FERAL.

His stomach lurched again, and he knew he couldn’t hold back the urge to get sick any longer. With a sudden burst of strength born of desperation, he pulled at the restraints holding his wrists until he felt one snap. With one arm freed, he was able to lean over the side of the gurney before emptying his stomach on the tile floor. 

The doctor, seemingly frightened by his sudden movement, quickly scruffed him, before injecting him with a syringe he hadn’t realized she had been holding. There was a quick pinch-like feeling where the needle was jabbed into him, then nothing but darkness, as blissful unconsciousness once again overtook him.

***

Saitama woke up, slowly and reluctantly, to the smell of clean laundry and fresh air that came in from an open window. The next thing he was aware of was just how terribly dry his mouth was. Was he dehydrated? Well that would explain why his head hurt like he was hungover. Was he hungover? Wait… why did his ass feel like it had been hit by a truck?

The last thing he remembered was… oh. He knew why. 

He turned his attention to the one who had played the role of the metaphorical truck. The Alpha was sleeping against his shoulder, bundled under one of the many blankets that were strewn haphazardly around the room. He absently ran his fingers through the blond hair while he thought about what he could recall before the first peak of his heat hit. 

It had been uncharacteristically bold of the Omega to make the first move like that. Everything after was just him pushing his luck. It was clear that the physical attraction, at least, was mutual. He wasn’t sure exactly what that meant for their relationship.

He had previously thought they would live like roommates who happened to be married, but they had become pretty close, and now it seemed like they would probably continue fooling around even when he wasn’t in heat. He knew now that his feelings were more than just the physical attraction, he was falling (had already completely fallen if he was being honest with himself) in love. Did he dare to hope his feelings would be reciprocated?

His mate stretched and snuggled closer in his sleep, the movement causing the blanket to slip down past his shoulder. The Omega felt like someone had doused him with ice water. With an unsteady hand, he pulled the blanket down to the Alpha’s waist. His mate’s upper body was covered in bruises. Many of the marks were clearly from bites, a few even looked like they had broken the skin.

He reached to shake his mate awake and ask him what happened, but when he put his hand on the Alpha’s shoulder, he realized some of the bruises lined up perfectly with his fingertips. He snatched his hand back as if it had been burned. What the hell happened? What did he do?

He tried to remember what had happened during his heat, but after the first peak hit, everything was a blur. There were some moments between waves that he could recall a bit, times when Genos was bringing him food and water, or moments where they were just resting and cuddling. 

He tried to sit up, but the movement made his head swim. The dizzy spell brought nausea along with it, and wasn’t that just great? He quickly shuffled off the side of the bed, only to collapse to his knees and empty his stomach on the bedroom floor.

“Saitama?” The Alpha’s voice called from back on the bed, “are you alright?”

“Yeah I’m f-” the Omega was cut off when he threw up a second time “Mostly fine,” he managed to say once he was done getting sick. 

The Alpha slowly got out of bed, carefully avoiding the mess on the floor. “I’ll be right back,” he said as he made his way to the door. Everything about the blonde, from his body language, to the dark circles under his eyes radiated exhaustion. 

Genos returned after a few minutes. He first helped the Omega get cleaned up and rinse out his mouth, before putting him back onto the bed. Then the blonde cleaned the mess that had been made of the floor. After leaving the room for a few more minutes, presumably to put the cleaning supplies away, he returned to collapse onto the bed. 

Saitama had spent that time staring at the ceiling as if it could somehow give him answers. He had no idea what to say, but some kind of apology was probably necessary. 

“Genos,” the Omega asked, “you’re looking… rough. What happened?”

The Alpha snuggled up next to him, nuzzling against his shoulder. Well that was a good sign, he doubted the blond would be so cuddly if he had done something unforgivable. 

“Your heat lasted five days,” the blonde replied, “with an average of four hours between peaks… ‘m tired.”

Saitama knew that the first heat after coming off long term suppressant use was usually intense, but that was… that was a lot. No wonder his mate seemed so worn out. It didn’t really explain what he needed to know most though. It was, on some level, a relief that the blonde didn’t even think to mention the bruises, maybe he wasn’t upset about it?

“What about your shoulders?”

The Alpha nuzzled against him again. “You were a bit rough but… I liked it.”

“Oh.” That… made sense considering what he remembered from before he was out of it. “So we… It’s like that, then.” He felt his face heating up at the thought of it. “I wish I could remember what happened. It sounds like we did a lot… and I don’t even know what any of it felt like. If I had known you were interested I would have said something sooner. I didn’t want to forget our first time.”

The blonde pulled him into a deep kiss. It wasn’t as urgent and desperate as the pheromone driven kisses they’d shared before, instead it was soft and sweet. “I’d be happy to help you create some lasting memories,” the Alpha said, “after we’ve had some time to recover.”

A few short beeps drew their attention to the phone that had been left forgotten on the dresser. The blonde glared in its direction for a moment, before reluctantly getting up to grab it, and bring it back to the bed with him.

As the Alpha read whatever messages he had received, his eyes grew wide and his body tensed. “Saitama,” he said, “the Fight-House was targeted by the arsonist. It was burned to the ground.”

Chapter Text

Saitama had been trying to ignore all of the reports about an arsonist setting fire to businesses. The main factor that seemed to connect all the incidents was that they didn’t know how the fires were being set. He had been hoping that they were actually unrelated, and that the media was making a big deal out of some old buildings with faulty wiring that just happened to ignite around the same time. 

It was harder to avoid thinking about it when the place that burned down had been his home-away-from-home for years. It had been somewhere he could go to get away from his parents, and vent his frustration.

“Can I borrow your phone? I’d like to call Fubuki, and it seems like you don’t have a house phone here.”

Genos looked up from the five days worth of messages he was going over. “You don’t have a phone?” The Alpha narrowed his eyes thoughtfully for a moment, then passed the device to the Omega. “Of course you don’t. Sorry I should have thought of that already, I’ll get one for you.”

The bald man just shrugged it off, and dialed in the number he had long since memorized. After a few rings Fubuki answered. She didn’t have much time to talk, as she was apparently busy dealing with “insurance bullshit,” but she did at least take a moment to confirm that no one had been in the building at the time of the incident. 

Now that he was satisfied that no one had been harmed, a more selfish part of Saitama wondered what he was supposed to do with himself now. Genos would be returning back to working in the lab soon, and it sounded like that would occupy most of his time. There was only so much cooking or cleaning that needed to be done for three people, and it seemed like the fastidious Alpha habitually did most of that stuff anyway. 

Deciding to leave tomorrow’s problems for tomorrow’s Saitama, the Omega looked back at his mate. The blonde was somehow looking even more exhausted than he had before. He was lying flat on his back, staring at the ceiling with his trademark scowl, tension practically radiated from him. 

The Omega started to gently run his fingers through his mate’s hair again, while he wondered what he should do to help. The Alpha seemed to be, understandably, on edge whenever the topic of the arsonist came up. Before, none of the places that were targeted were even in Z-City, but now they had burned down a place that the mates frequented.

The fact that he was injured wasn’t exactly helping either. Even if the Alpha had enjoyed it at the time, it still probably put a lot of stress on his body.  

Saitama only somewhat remembered his health class in high school, there had been a lesson on how particularly rough Alphas should do some kind of aftercare for their Omegas after their heat was over. He had mostly ignored it, because he didn’t really think it would be relevant for him. Now he regretted not paying more attention.

He knew, at the very least, that Genos seemed to respond well to physical affection. Even just the slight contact of playing with his hair seemed to be helping a bit. The Alpha’s furrowed brow had relaxed slightly, his expression softening. “Can you roll over on your Stomach? I don’t really know much about how to do a proper massage, but I’m going to rub your back.”

The Alpha hesitated, giving him a questioning look.

“When you said I could do whatever I want to you, did you mean just for that night, or more,” the Omega gestured vaguely, “in general?”

The blonde swallowed hard. “In general,” he responded, a slight blush spreading across his face.

“Then roll over for me,” the Omega insisted, “I just want to help you relax, alright? I’m not going to maul you.”

Genos smirked slightly, in a way that implied he wasn’t entirely opposed to being mauled, before flipping over onto his stomach, with his arms folded under his pillow.

The Omega pushed the blanket back down to the edge of his mate’s pajama bottoms to reveal his back, taking his time to enjoy the view. Despite the fact that the Alpha had only started lifting weights recently, the muscles of his back were well defined. Bearing the heavier weight of his prosthetics all day was probably a work out in and of itself. The skin of his back was slightly less scarred than his front, with a long strip that was mostly unmarked along his spine.

There was something about seeing his mate like this that made his heart ache. The Alpha was actually comfortable around him without a shirt on. It felt significant. It felt like undeniable proof that things between them were different now, that they had become closer. 

He gently ran his hand up along the smooth area, then across the textured skin of the Alpha’s shoulders, then back down again to rub circles around the small of his back. It didn’t take long before he could feel the tension in his mate’s muscles practically melt under his touch. 

Saitama adjusted his position so that he was kneeling next to his mate, so that he could have both hands free to try to work on some knots in the muscle around the blonde’s shoulders. The Alpha let out an appreciative sigh, and his eyes drifted closed. 

The Omega couldn’t help but feel a sense of satisfaction at how easily he had been able to get the blonde to relax. It seemed like he had been right about how receptive Genos was to physical affection. He could hardly believe that the Alpha that had such an intimidating presence around others, could be so incredibly cute when he let his guard down. Saitama wasn’t usually a possessive person, but a part of him really liked knowing that he was the only one who would get to see his mate like this.

His hands made their way back down along the middle of the Alpha’s back, before he stroked his palms gently along his sides. The blonde’s back arched, and he let out a soft gasp that seemed to make warmth pool in the Omega’s core. Christ, how did he manage to sound so incredibly good?

The blonde flinched, seemingly surprised by his own involuntary reaction, and buried his face in the pillow. How did he manage to be both sexy and cute at the same time? 

The Omega couldn’t resist running his hands up and down his mate’s sides a few times, enjoying the way his mate whimpered softly, and how the muscles trembled slightly under his hands. He leaned down to sniff along the side of the Alpha’s neck, where his scent was strongest, and sure enough, the telltale scent of arousal was already becoming noticeable.

How had someone so sensitive managed to hide his attraction for an entire week? It was so obvious now, Saitama must have been completely oblivious to have missed it. If he hadn’t been told that Genos wasn’t into Omegas, he probably would have noticed sooner.

That was something they should talk about. They would have to get better at communicating in general, really. The Omega didn’t want to have any more miscommunications, not when things were starting to go so well. He frowned slightly at the thought, talking about your feelings meant being forced to acknowledge you have them in the first place. Repressing his emotions and acting unbothered had been his default for years, it wasn’t going to be easy to break the habit.

“An Alpha’s sex drive sure is something,” that wasn’t exactly what he had intended to say, but whatever, the conversation had to start somehow. He dragged his fingertips down along either side of the blonde’s spine, enjoying the way his back arched when his hands reached the edge of the pajama bottoms he was wearing.

“Ah… Sorry,” the Alpha mumbled the apology against the pillow. How he managed to still be shy after how they had spent the last five days was a mystery. 

“It’s fine,” the bald man replied, “we’re bonded, married, and I’m kinda… intentionally pushing your buttons a bit. I like the way you react when I touch you, Genos.” The low moan the blonde gave in response was almost unfair, how was he supposed to have a proper conversation when his mate was making sounds like that? 

Sure, Alphas had the highest libido of the different presentations, but Omegas were a close second. He would have to knock it off if they were going to manage to actually talk to each other. The Alpha was exhausted and had said he needed time to recover anyway.

He had his mate roll onto one side, and curled up against him, his chest flush against the Alpha’s back, an arm draped across his waist. Genos let out a contented sigh and snuggled back against him, apparently perfectly comfortable being the “little spoon.”

Saitama spent a moment mulling over how to even start, saying ‘we need to talk,’ would likely make his mate nervous, or put him on the defensive. 

“There’s something I’ve been wanting to ask you about,” he said, trying to sound as neutral as possible. “At our wedding reception someone told me that you can’t stand Omegas… is that… is it true?”

The blonde froze up for a moment, so tense it felt like cuddling with a statue. “Was it Sonic?”

“Yeah,” the Omega replied.

“I knew it was him, that little shit,” the Alpha growled, “when I get my hands on that prick I’ll fucking defenestrate him.” After a moment the blonde heaved a heavy, defeated sounding sigh, “he wasn’t lying though, I… I had spent the entire week before our wedding complaining that I didn’t want to marry an Omega. It’s not that I hate Omegas or anything… I just… I didn’t think I could ever find one attractive. I refused to meet you before the wedding because I thought if I did, I wouldn’t be able to force myself to go through with it.”

He briefly tightened his grip on the Alpha’s waist and bit gently at the nape of his neck. The Blonde’s breath hitched, and his back arched slightly. “You are attracted to me though,” the Omega observed, “is it… because I look more like an Alpha?”

“I can’t deny that,” he replied, “there’s more than that though. The more I get to know you, the more there is to like about you.” 

“Do any of my more… Omega-like traits bother you? Like my scent, my heat cycle, building a nest in your bed, or… um… the slick?”

“If you’re asking what parts of yourself you need to hide or suppress to meet my preferences, the answer is none. I thought I wouldn’t want to be with an Omega, because I couldn’t stand the thought of being with someone weak, feminine, and submissive… those words don’t describe you at all,” the Alpha replied. “I lo-... like you, exactly the way you are. I’m glad that you’re an Omega, because if you weren’t, I would have had to marry someone else. I’m sorry I let you think I wasn’t attracted to you, I was just… I was being a coward. I thought… you would reject me.”

“You don’t give yourself enough credit Genos,” he replied, “even if I was shallow enough to reject someone over their appearance, I wouldn’t have turned you down. You’re really hot. You drive me crazy, and you don’t even realize how sexy you are.”

The Alpha sighed again. “It isn’t just that. Even if I wasn’t… like this, you would still have good reason to hate me. I bought you. I bought you from a fucking auction that sells people like they’re goddamn livestock. I made you marry me without even having the decency to meet you first, all because of some stupid pack law bullshit.”

Saitama nuzzled against the back of his neck, hoping the gesture would help him feel better. “My parents sent me to the auction house, they’re the ones that put me in that position, not you. If you didn’t buy me, eventually someone else would have.” The Omega held his mate close and trailed kisses along his shoulder. “As soon as it was just the two of us, you gave me a choice. You didn’t just take me, you didn’t demand anything from me, you offered yourself to me. If I wanted out, you would have just let me leave, I’m sure of it. I didn’t just want my autonomy, I chose you Genos”

The blonde let out a choked sob, his shoulders trembling, before he rolled over to wrap his arms around his mate. He buried his face against the Omega’s shoulder, breath hitching as inky black tears streamed down his cheeks. 

The Omega ran his fingers through the blonde hair and kissed his forehead, before trying to wipe the tears away. It seemed like as good a time as any to tell his mate how he really felt. “I… I… um.. I really like you Genos. I like you a lot.”

Shit. That wasn’t what he wanted to say. Not even close. It seemed like he would need to get more practice when it comes to the whole communication thing. He didn’t need to rush things anyway, they would have the rest of their lives together to work on it.
