OK BUT IMAGINE THIS AU PLS
Fubuki as Saitama and Genos’ surrogate mama! (I’ve read plenty of fics where Genos is able to give birth bc he gets given a metal vagina and uterus and stuff but this is an au where that def doesn’t work)
I think Fubuki is too much of a MATERIAL GORL to ever want kids and that responsibility, but when she hears Sai and Gen are ready for kids and struggling with her small options, she starts to think. She loves Sai and Genos (way more than she’ll ever admit to them) and wants to help them, so maybe one day she barges into their apartment like usual and Saitama’s like hey buki what’s u— and she’s like “Saitama I want you to inseminate me 🧍🏼” and Saitama’s choking on his drink while Genos is trying not to fire all his cannons at Fubuki.
Cut to chubby pregnant Fubuki! They got artificial insemination with Sai’s sp3rm (something Saitama doesn’t wanna dwell on, the idea of her giving them a baby is one thing but him being the one to get her pregnant and the baby biologically being from him and Fubuki? Horrifying) and Fubuki’s constantly hungry. She eats extra healthy tho bc she wants the baby to be healthy af, buuuuut sometimes she’ll hole in her room at night with some ice cream.
Tatsumaki immediately knows as soon as she sees Fubuki that something is off a few weeks after the insemination but knows for sure two months in bc of her esper senses or whatever telling her that there’s something living in Fubuki. She flips tf out and is like “FIRST OF ALL I THOUGHT YOU WERE GAY?!?? (I hc her as lesbian in my aus mostly) AND WHO TF WAS STUPID ENOUGH TO GET YOU PREGNANT??? WHENS THE ABORTION SCHEDULED ILL HELP YOU GET ONE IF YOURE SCARED 😡😡🤬” Fubuki takes a lot of time to eventually get out that she’s being a surrogate but never says who for bc she knows Tatsumaki would have a STROKE. It’s only when the baby is born does Tatsu finally figure it out and shit hits the fan.
Genos cries whenever he and Sai get to feel the baby kick and is overjoyed that they’ll have a little bundle soon. He meticulously plans out breaking down a wall in the apartment to make another room for the baby and plans out the theme, paint colors, flooring, aesthetic, everything and drags Sai along with it. He and Fubuki have so many arguments on paint colors but she usually wins when she cheats and acts like she’s getting bad cramps or something hehe.
I’ve got so many more ideas for this au im just tired 😭 will prob add to this!
