A few of my favorites from the Golden Age greats:
Masterwork: Millie by Wolfram Sparks
Partial comic adaptation: By the False Wolf
This one is brutal and great: Fidget Toy by Peppermint Parchment
More recent,
A great newer story: Holy Shit They’re Real by Reddisketti
Also,
Humbly submitted: Jellybean’s Tale by yours truly
Jellybean continues in non-illustrated form: Jellybean Act 2
If you liked Millie, I am working on a continuation: Slate’s Fate
