yessssss i'm so glad you asked!!!! here are a few that come to mind!!

shorter ones/pwps:
https://archiveofourown.org/works/61378723 sweet soft mpreg mimo
https://archiveofourown.org/works/36412042 quite popular but it's monsterfucking and oviposition so you may not have read it? lmao
https://archiveofourown.org/works/48801667 free use minho x 3racha
https://archiveofourown.org/chapters/80653582 from 2021 so maybe you have not read it either?
https://archiveofourown.org/works/80710431 alpha minho but vers minsung with a subbier minho, this one deserves way more love!

longer ones:
https://archiveofourown.org/works/51665206 super long vers arirang, such a wonderful fic, i think about minho's nipple piercing in this fic every day of my life like i pray to it before every meal it's that serious to me.
https://archiveofourown.org/works/69072361 another super underrated minsung one from last year's slickfest, if you want something longer with more worldbuilding, so pretty
https://archiveofourown.org/works/73774731 you've probably already read this one but this fic singlehandedly made me like mpreg, it's the omega minho ever to me i love this fic sooooo much.

i hope you find one that you like and haven't read from these! i want to do a deep dive for some more niche ones now one day so stay tuned
