Chapter Text
Izuku was supposed to be living his best life right now. His beloved Kacchan, his used-to-be bully turned friend, turned lover is now married to him. They've been secretly married for the past 5 years and Kacchan is at the top of his game, being Japan's current number 3 hero. It won't be long until he becomes number 1, as Kacchan would always remind him with great determination.
He didn't mind having their marriage kept secret, although all his friends were pretty against it.
'Izuku, honey. This is a major red flag!' Ochako, or Hero Uravity as she was known to the public, had commented on it while they were hanging out once.
'I really don't mind, Uravity-san'
'Zuuuuuku stop! we've been friends since we both started in the agency! SAY OCHAKO!' she demands as she squeezes his cheeks.
'Yes, but we're in public, Chakoooo' Izuku whispered in the brunette's ears. They both broke into a fit of giggles.
Izuku had no problems striking friendships with the heroes in his agency. He and Ochako started working at around the same time 6 years ago. She, a hero intern at the time, and he, a budding assistant hero analyst.
Izuku had loved Katsuki since they were children. He didn't care in what way he could have the blonde, for him, it was already a great miracle to be married to the love of his life.
Being married in secret had done a lot of good as far as he was concerned, In his love-drunk mind, he thought it was Kacchan's way of protecting him. Protecting their privacy and also protecting his life as well as their pups (if ever they would have some in the future). Hero work meant you'd have to put your life on the line and the same goes for your family members. That's the reason even All Might. the world's greatest hero remained single throughout his career.
Kacchan was already doing him a favor, he thought. Kacchan didn't need a quirkless Omega like himself to drag him down, getting kidnapped or targetted by villains to use as leverage against him. This scenario had played a whole lot in the past. Kacchan loves him enough to marry him despite his uselessness and the obvious liability that he was.
He was married to Ground Zero! Sexiest man in all of Japan! The #3 Hero! He considered himself lucky. Luckier than most.
Until today of course.
Izuku made his way to his and Kacchan's secret apartment. It was a discreet and comfortable condo unit that Katsuki had gifted him on their wedding day. They still lived separately despite being married and they were only allowed to be a couple and do 'couple stuff' whenever they were in their shared apartment. A safe space for their lovemaking, their heats, and their ruts. A place where they could hide from the public and be in each other's arms when the blonde was free from hero work.
Izuku had heard from one of the police officers that Ground Zero had just finished a big buy-bust operation in the nearby area. Working as a full-time hero analyst now has helped Izuku bring valuable information to Katsuki so he could work more efficiently and compete against other heroes. Izuku's input had always put him at an advantage against others and Izuku loved his job. He could fawn over heroes as much as he wanted and it didn't hurt that he was always one of the people who knew about secret operations such as this. The success of Ground Zero's operation hadn't reached the media yet and so Izuku had hastily gone grocery shopping so he could surprise the blonde with a celebratory dinner.
He walked into their apartment when the thick scent of Kacchan's arousal hit his nose in such a way, he had to catch himself from falling face-first into the floor of their secret apartment. It hung in the air, heavy with lust. An all too familiar scent he'd known from their years as a married couple.
But that's not what's bothering Izuku at the moment. Katsuki's smokey caramel scent is mixed with someone else's.
A sweet bubblegum scent was mixed in the air, with the same heavy undertones of arousal. Falling on his knees at the overwhelming pheromones of his mate, he noticed a messy trail of discarded hero clothes leading to their shared bedroom. Only then did Izuku realize there were sounds coming from inside of the room. His mate's familiar grunts of pleasure along with the sweet voice of a woman begging for Katsuki's knot.
He quietly crawled on all fours towards the bedroom door, thankful, so very thankful that he wore his scent blockers that day and even put on a scent patch against his scent glands.
'Faster Alpha! ah...n-need your knot!' the woman's sweet voice had said.
Izuku peeked with horrified eyes inside the room, thankful that their apartment's lights were all off except for the bedroom, giving him the opportunity to see inside without being caught.
'You like it rough, don't you? You little slut' Katsuki says against heated moans as he slaps the woman's ass. The wanton woman was on all fours, bending and taking his husband's cock from behind.
'Ah! Yes! More, more Alpha. I want it. I want it rough!'
Katsuki wastes no time thrusting harder into the woman's cunt, with so much force that for a second, Izuku thought he might break the woman in half. But then Izuku would never know. He was no hero like the woman in his husband's arms. She was obviously built to take his powerful thrusts. A powerful Omega woman unlike himself.
It was his husband's long-time hero partner ever since he started working as a pro. None other than Maboromicamie.
Izuku watches as the blonde woman writhes with pleasure on their mating bed. His husband clutching the woman's thick powerful thighs as he breathlessly assaults her from behind, filling the room with slap after slap of their skin, the sinful melody of their vigorous love-making.
Upon seeing his husband's thrusts becoming more erratic, his beautiful chiseled face contorted in pleasure, Izuku could no longer hold in the bile rising from the pit of his stomach. With all the strength he had left, he picked himself up from the floor, grabbed his groceries and ran outside the apartment into the open city. Tears streaming down his face. His sobs were uncontrollable, threatening to bust his lungs open with all the heaving and the screaming as he ran past confused and worried faces across the street.
He ran past people, trampled against sidewalk vendors, and even fell face-first onto the concrete road. That didn't stop him from heaving. His small body shaking from shock and pain but he immediately picked himself up and ran and ran until he was spent.
Everything was a blur. He had no idea how he'd managed to get back into his apartment or how he'd ended up in his bathtub, curled into himself as he lay there, half of his face above water.
He was exhausted beyond belief, both emotionally and physically. He ran quite a distance from their apartment into his own. He doesn't know how long he cried like a madman, but he guesses it was enough to make his eyes feel as coarse as a dessert. He honestly didn't know what he was feeling right now. He felt numb. He felt disgraced. He felt weak.
Alpha abandoned us.
His Omega was shattered. He could feel himself growing weaker by the minute.
He felt stupid for not seeing all the signs sooner.
Kacchan had probably been with the Omegan Hero for a while now.
He particularly noticed Kacchan's distance for over a year now, but just brushed it off as the hero being too tired since he was aiming for the number one spot.
All the late messages, the missed dates, all the times Kacchan has forgotten their anniversary, it all made sense now!
How could he be so stupid? It had been a whole damn while since they even had sex.
Now he understands completely. He was fucking someone else.
Izuku was sick and tired of being the weak and useless Omega hiding behind Katsuki Bakugou's shadow.
He finished his bath and went on with his evening as he normally would. He didn't want to think about his unfaithful husband. He's wasted 5 years of his life. It was time he put his love, his madness in the backburner.
He cooked a nice meal for himself with the groceries he bought and had his dinner in peace.
After that, he lay a mattress below his couch and decided to binge-watch all the All Might movies he had at his disposal.
What better way to end the evening than an All Might movie marathon?
He would deal with all the useless baggage of emotions tomorrow. For now, he wanted to fill his head with hopes and dreams from his childhood hero.
He smiles a genuine smile after the events of that day when he nears the finale of the first movie.
'Do not fear! I AM HERE!'
Izuku smiles as the movie's credits begin to roll, letting himself fall into a dreamless slumber.
