Parasitic

Freed from the Fresh parasite's control, Sans finds himself in an Underground that isn't quite his own.
A slightly gentler if still slightly harsh ending for a character with a disturbing fate.

This was written purely for entertainment purposes so please no hate...
I read a fanfiction about this in the past and thought I'd make a oneshot out of it. It's mostly written from what I could remember with myself making up things to fill in the gaps.
I don't know the original author but quotes to them for the amazing idea.

Sorry in advance! I have dyslexia so spelling and gramma might be all over the place. I did try my best to check everything!
