Summary
Alpha, Beta, Omega, three different gender traits. Alphas at the top are strong, powerful, able to do most top jobs; Betas are the working class, and then there are the Omegas. They are to be married off young to alphas to continue making more strong alphas. Omega sare treated as less than humans. Even worst, Quirkless omegas are useless. They can’t be heroes, and alphas always overlook them if an alpha can’t get offspring with a powerful quirk, and the chance that the offspring would be quirkless too. What's the point?
Izuku, a quirkless male omega, believes he would never be forced into mating. He made it this long without anyone being interested in him; he passed the age when the chosen mating would be. Izuku knows he’ll never be a hero like he wanted to be. Omega heroes and quirkless are not a thing. Choosing a safe path in life, he takes over a bookshop called One for All. His life is quiet and peaceful. Until the prime alpha, Dynamite, rushed into his shop to hide. Izuku’s life hit the fan. From having a quirk, a mate who would protect him with his life. His bookshop has so many secrets. M/M omega/alpha Izuku/Katsuki.Series

Summary
Finally, Izuku set down his chopsticks. He'd barely eaten half his meal, but he couldn't stand this anymore. They needed to address the elephant in the room—the fact that their biology thought they were compatible, even if everything else screamed disaster.
"We need to talk about this," Izuku said, his voice low and controlled.
"No shit." Katsuki leaned back in his chair, arms crossing over his chest. Classic defensive posture. "The matching system is clearly broken."
"Clearly." Izuku took a breath, steeling himself for what he was about to propose. "But we both need our licenses renewed. And according to the Commission, we need to be mated to qualify."
"I'm aware, nerd."
"So, I have a proposal." Izuku met the Alpha's eyes directly, refusing to back down. "A contract relationship."
Katsuki's expression didn't change, but his scent sharpened with interest. "Go on."OR: Katsuki and Izuku are nearing 30's and as Pro Heroes, unmated alphas and omegas are seen as liability. They need to be mated or their licensed unrenewed. Izuku got a proposal and Katsuki dive into it. Fake Relationship gone wrong and all the sexual tensions behind.

Summary
Something felt… wrong, very wrong.
“Izuku.”
“Y-yeah?”
“Something isn’t right. It- there’s something…fuck this sounds so cliché. There’s something in my fucking pants.”
“Like… your…”
“Like more than just my dick.”
“Uhmmmm…”
Neither of them moved or spoke for several long minutes. The crickets and cicadas in the forest made a soundtrack to their awkward silence.
_____
OR: After a trek up to the mountains to re-capture escaped prisoners, Katsuki and Izuku get hit with a quirk that makes their filthiest dreams of each other a reality. It changes the course of their lives, for the better. Or at least, it made things more interesting...
**Happy Kinktober!**

He whispered right into Izuku’s mouth, “Checkmate.” -

Summary
“Please, Katsuki,” Izuku says quieter now, sinking back against the car door, “I cannot do this with you right now. I just can’t. We can’t change what’s already happened and, frankly, I wouldn’t want to. I’m glad you’re able to live your dream and-”
“But what if I’m not?” Katsuki interrupts him, a grim look on his face, “What if I’m fucking tired of this shit? What if I’m tired of people picking and prodding at me all day? What if I’m tired of reading shit about me online? I love acting, don’t get me wrong. The damn thing’s my passion but what if I love you more?”
“Katsuki…” The word comes out slowly and carefully from Izuku’s mouth, just barely sneaking past his lips.
Katsuki replies, a bit more confident than Izuku himself, “Izuku.”
They stare into each other’s eyes for a little while, neither of them breaking eye contact and neither of them really wanting to.
***
OR, Katsuki comes back to Japan for the holidays every year and makes sure to spend as much of it as possible with Izuku but, this time, something changes.

Summary
“W-welcome home, Sir.”
Staccato steps thudded against the hardwood floor until they came to a stop before Izuku. Katsuki reached a hand out and softly twirled a lock of viridian hair around his finger before tracing it down his jaw and then grasping him by the chin. The sound of Izuku’s breath catching in his throat made Katsuki’s chest swell, and he chuckled as he facetiously tilted Izuku’s head side to side before lifting it up so their eyes met.
“You look good like this,” He finally said as his thumb ran along Izuku’s plump bottom lip.
“In a dress or on my knees?” Izuku asked, eyes lidded as his lips brushed coyly against Katsuki’s thumb.

Summary
Tony had always expected that his awful kink would never be brought up to his alphas. It had ended more relationships than it had helped. But when Steve and Bucky find out about it, they’re… supportive? Tony has no idea what he did to deserve these two alphas that are willing to indulge his kink but he’s glad. Of course, they have a few kinks of their own that they’re willing to divulge now too.

Summary
“Deku,” Katsuki murmurs into his husband's skin, warm under his lips. “I’m not going for sufficient.”
Deku licks his lips, restless.
“I want to make my husband such a mess,” he says, pressing down, a hand settling right next to Deku’s head, “that everybody who sees him knows he got fucked within an inch of his life not once, not twice, but until the moon gave up first. I want to make a goddam puddle out of his spine, make him taint his tongue with my name, exchange his freckles for my teeth marks, make his hole as sloppy and wrecked as possible from my cock alone.”
He bites up Deku’s jaw, grinding his dick against Deku’s ass. “I want to make you beg for mercy knowing you’ll never get it. Does that sound sufficient to you?”
-
After a long week, a long month of back-to-back missions, of spending barely any downtime with his husband, Katsuki wants two things.
One: some good food, a hot shower, and a quick nap, in that order.
Two: take Deku apart so thoroughly that his husband struggles to breathe, let alone walk properly the next day, and wears Katsuki's affections on his skin like a brand for weeks after.
