Summary
Dispono was, in a word, incredible.
The people of every shape and size, all sharing the same street and the same space and the same air. Well, that wasn’t entirely true. A few had breathing apparatuses to give them the proper respiration, but most of them were sharing the same air. Izuku was breathing the air that Hyaeromyns had breathed. He was walking down the same streets as Lepecapri and passing the same shop owners and flashing advertisements as Cagatils. Most of the time, there wasn’t a single other Human in sight.

Or: Midoriya Izuku, born and raised on Earth and only a member of the P.S.C. Starnavy for a little over two Earth weeks, reports to his new station aboard the U.A. CloudSound.
Technically part of a series, but reading the first one isn’t completely necessary.Series

Summary
I've been seeing a lot of Midoriya and Shinsou being the ones to get kidnapped by space traffickers but I thought I'd give Yaomomo a turn. This was inspired by a lot of what I read under the "humans are space orcs" tag
--------I was just outside training with Kyouka and then something pricked me and now I'm in a grey cell with a big black cat staring me down. What on Earth?

Summary
When Kaminari mentions something about strange lights, Kirishima dismisses it as another of his friend's crazy antics. After all, Kami did get into it with an electric fence as a calf. There's no telling what's real and not with him.
Then the water level at the farm's swimming hole starts dropping--and fast. It's not the heat, Kirishima's sure of that much.
Things only get crazier when new bull hybrids show up for some summer fun. Just when Kirishima thinks he might be getting somewhere with one of them, those strange lights return--but this time, he's the one who sees them.
Turns out he has an intergalactic admirer who can't stand the bull Kirishima was trying to woo. With a hot alien promising to take him to the moon and beyond, how will Kirishima ever find his way back to Earth? Does he even want to go back?

Summary
Being a teacher was super rewarding.
Izuku loved clocking into work each day, seeing his students’ faces, guiding them, offering a listening ear, and sometimes being a shoulder to cry on.
But he'd be lying if he said there weren’t any downsides.
Specifically, the lack of a sex life, good thing he meets a friendly hiker on his day off to lend him a helping hand.

Summary
Izuku Midoriya había sido seleccionado para los esfuerzos de colonización en K1854-b, en la constelación Andrómeda. Había llegado al planeta con diecinueve años terrestres, siendo un novato nervioso, pero a los treinta y seis, se había convertido en un teniente agrónomo que inspiraba respeto entre los demás colonos. Sin embargo, no se había ganado la obediencia de los Exari por medio de la violencia, más bien, gracias a su sentido de justicia y claramente, por algo de amabilidad escondida.
El primer joven albino que trajo a sus tierras, otro rechazado de cabello extrañamente rubio y piel blanca, fue el más difícil de convencer, pero también fue quien más valió la pena
Katsuki era su perla resplandeciente bajo la estrella roja de ese planeta.Series

Summary
After finding unknown alien technology on a scouting expedition, spaceship engineer Bakugou Katsuki is tasked with deciphering what it is and how it works. The pod has his entire crew baffled, and even stranger is the creature that's come out of it.
Sure, it looks, talks, and acts just like Katsuki, but there's something off about it. Something about the way it watches him work isn't quite right, and Katsuki is willing to do whatever it takes to figure out what's going on. That is, if he can survive the constant barrage of flirtation and innuendo the creature seems hell-bent on tormenting him with day in and day out.

--Enough people had told Katsuki to go fuck himself throughout his life; maybe he ought to take their shitty advice for once.

Summary
Izuku held still, head back and mouth wide, as the creature took its sample. The swab ran lightly along the back of his tongue, hypersensitive but not uncomfortable; ticklish when it shifted to stroke the inside of his cheek. The alien’s head dipped low, almost to Izuku’s level, revealing the fine texture of orange scales along the planes of its face.
Fascinated, he reached out and touched his fingers to its lipless mouth.
Izuku spent his whole life dreaming of aliens. Abduction offers the perfect opportunity to get closer.

Summary
Never did he feel more lucky to have his job then the day they took in 451121. Being the head of the extraterrestrial department gave him full unsupervised access to the sexiest thing he’s ever laid his eyes on.
Katsuki won’t lie, he's always had a thing for smaller men and women. He likes how their faces contort in pleasured pain as they take his cock. He likes how small they are in comparison. How he could easily pin them down and fuck them, without them being able to do a thing to stop it.

“Oh.. that’s okay. We don’t have to do it.. We just can’t be friends.” Katsuki pouted, and reached for his shirt.
“No! I w-wanna be friends..” Eijirou said, and slipped his pajama pants off his little cock sitting flaccid against between his legs. Eijirou’s eyes stared at Katsuki’s semi hard cock as he slipped his pants off as well, and the boy tilted his head to the side like he was observing him

Summary
But overall, he was a good roommate.
Sure, he made Kirishimas insides twist everytime he would flash the redhead a smirk, and Kirishima’s heart would sink everytime the alien wandered out to tinker with his spacecraft, reminding Kirishima of the deadline on their friendship. And sure, the human wanted to kiss Bakugo, and never let him go, and he hated himself for the way he reacted to the aliens side profile-
But he was a good roommate.
