Headless Brother (aka Dirty Brother Killer)

A partially inaccurate (to the game's storyline) Undertale fanfiction about Frisk's relationship with Sans after killing his brother. Frisk promptly seeks his forgiveness and attempts to make honest amends with the skeleton. Soon after the incident, Sans' father unexpectedly steps in and takes surprising action.

This is not one of my regular short stories. I will try to create a full book-length adventure with this scenario.
I hope you enjoy it. Now go and have a good time.
