Anthropomorphic is a 4,8k NON anthro horror fic. Kinda.
Daring Do brings along Lyra to an expedition due to the unicorn being an authority of sorts regarding humans. Lyra brought her girlfriend with her.
Boy, this one sure knew how to work the despair. This is a body horror story, and I think one of the best ones I've read.
I don't want to spoil much, since the story is quite short, but the degradation of their bodies as time goes on, and the way Bon Bon clings to hope is quite enthralling.
This gets a whole-hearted recommendation. If you like horror and want something short, but effective, this will do the trick.
