Summary
Katsuki sits on the ledge, unmoving. He stays motionless to ride out the storm of emotions that's brewing inside his heart.
Then....there's a click.
A repeated sequence of them, higher in pitch, followed by another desperate song. Clicking and chattering, a form of echolocation, meaning-
Something, someone, is trying to find him.
Rich, shimmering, beautiful shades of green.
Another mermaid.
OR: Katsuki is a mermaid, and to his knowledge, the very last of his kind in the entire ocean.....or so he thought.

Summary
Katsuki is a hot-shot model laying not-so-low on campus. He gets whatever he wants from whoever wants to give it to him. That's what he's supposed to do, right? He's a household name, after all. Yet despite it all...it just isn't thrilling. No matter how much he rebels, no matter what or who he does, it's all so...boring. Enter campus celebrity and goddamn edible sweetheart Izuku Midoriya and well...things get not-boring very quickly.

Atypical by Cloudsu
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)
01 Jul 2023
Tags
Summary
Katsuki's not like other omegas... except, he kinda is. At least, he's got the whole "go into heat and be miserable" thing going for him. That docile, prim, and proper attitude though? Not so much.
It's for that reason that he ends up at a matching house and for that reason that he finds himself with a very atypical mating arrangement soon after. Though, at the end of the day, if he's being honest, he really, really wouldn't have it any other way.

Sixty-9 by Cloudsu

Summary
“Alright, alright, I’ll do the honors then,” Katsuki states, shaking his hand with the dice in it. He throws them practically across the room when he drops them so Izuku shoots him a look.
“Good going, Kacchan,” he mutters sarcastically. The blond flips him off with a sneer.
They both get up to look at the numbers and Izuku puzzles.
“Ninety-six?”
A huff. “No, dumbass, sixty-nine.”
Sixty-nine. Right. The little bar under the nine means… Wait. Uh oh.
--
Or, Izuku can't, for the life of him, figure out how to get from clothed dry humping to actual sex. He phones a friend who suggests a little dice game and well... the rest is history.

Summary
Izuku has been watching him all night, for days, weeks, months—slowly, his eyes have tracked every movement of his body under the pulsing club lights. This has never been his scene, but he’s all too willing to let it be if it’s Katsuki’s, just for now, just until he’s worked up enough intel to dive in, to meet him, to press his body against his, sway their hips together, and drink in his gasps and moans made sweeter by the liquor.

Summary
He said, “Me?”
Izuku nodded. “You,” he confirmed. “I—it took me a while. To realize how I felt. I was just so used to having you around that I didn’t realize. It wasn’t until Uraraka asked me out that I realized I didn’t want her like that, because I wanted you.”
“Shut up,” Katsuki said. “Shut up, Izuku, you—you have to be for real about this, I’m not fucking around, I’m not—”
“I am,” Izuku assured him. “I mean it, I’m for real. I want you. I love you. It’s you, Kacchan, it’s always been you.”

Winter World Waits by lalazee
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia
25 Dec 2020

Summary
Tonight is the deepest chasm of darkest night, and the world is aglow with laughter and light. Bells cling to boots, jingling merrily with every step, and the deep baritone of warrior voices in song shake snow from trembling boughs above their heads. Thick pelts of silver and tawny fur flicker and catch the candles’ warmth, weighing down the backs of villagers and children alike as they trawl through calf-high snow and towering forest.
The sun will not come for hours yet, and all the animals are curled in the depths of earth and tree for months still. But here, in the dense clutch of the woods, walking in joyful procession, is warmth. Family.

Three-Hundred Thousand Words by lalazee for dextra
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia
17 Dec 2019
Tags
Summary
Deku had done a lot of stupid things in his lifetime, but none so stupid as staying up all night jacking his dick raw to fanfiction of him and his best friend. Stupid was probably a very mild word for what was occurring in his life, but he wasn’t about to pull out a fucking thesaurus and look for a word that better suited his specific brand of idiocy.

Summary
“You’ve gotta be fuckin’ kidding me,” Katsuki said. “You did not just ask me—me—to try and date your loser step-brother.”
He wasn’t even going to say Deku’s name out loud. Wasn’t giving him the time of day, even in a conversation about him. That weird awkward virgin was not worth his precious time, and certainly not what Kirishima was suggesting.
“But Bakugouuu,” Kirishima wailed, hanging off Katsuki’s arm with monster meathead jock strength. “My dad said I can’t date if Deku doesn’t date. Do you understand what that means?”
“Less chance of knocking someone up and creating more of you in the world?”

Summary
Well, in a day of revelations, it turns out that Izuku isn't as vanilla as Katsuki previously thought. Unfortunately, that fascinating discovery is overshadowed by Izuku's dumbassery, because he has zero concept of aftercare.
"Don't go to anyone else," Katsuki says, because screw it. He can do a better job anyways.
Or; Katsuki finds Izuku on a bad drop.
