First of all here is a link to my AO3 where I’ve posted a few things I’ve written that you can check out.
As for things written by people more talented than myself:
Honeyboy by dollylux (~6000 words)
Underage wee!chesters who can’t keep it in their pants as well as panty!kink and a little exhibitionism. This one is super duper hot mmm.
The Ballad of the Invisible Boy and its sequel Two-Headed Boy by dollylux (~270000 words total)
Gosh okay. These hurt like crazy but they are so good and so in character and it is definitely worth your time to read them even thought they’re longggg. Read the warnings though! It’s important!
A Thousand Touches by Cha, anyothergirl415 (~30000 words)
So much codependency here. Weecest where Sam is mute and basically communicates through Dean. It’s great.
Put Your Ray Gun to My Head by eugara (~13000 words WIP)
Futuristic space AU that has amazing characterization and its hilarious and hot all at the same time and I can’t wait to read the whole thing when it’s finished.
Slow Ride by bewaretheides15 (~3000 words)
What would a fic rec list be without impala!sex, so here ya go. It’s beautiful and delicious.
Wolfpack Verse by tabaqui (idk the wordcount but it’s long)
AU written from an outsider’s pov. The boys and John are pretty dark in this one but it’s really hottttt.
also I hope this link works
The Theory of Relativity by wutendeskind (~20000 words)
Really great retired fic that diverges from canon after Swan Song.
Like Staring Into the Sun by nyxocity (~20000 words total)
These are so goddamn hot. Short fics that could be read separately but they make more sense in order. Basically Sam+Dean+girl and amazing smut.
So there’s a lot of different things to try here and it’s kind of all over the place but I hope you find something you like!
Also I recommend thewincestlibrary for more great fic recs, they post all kinds of wonderful things. Happy reading!
