Sans' friends pull a prank on him that leaves them scrambling to fix things. Some friends don't feel like they need to do anything, he's just an idiot. Some friends feel a need to try and fix things. What WAS the prank, and what are the consequences? Post-Pacifist. Genocide mentioned slightly, not post-genocide. Chara not included. RatedT for mild violence and occasional swearing.

When Sans is forced into being the hero once again, he must team up with different versions of himself to stop Error and his plan to... well, to do something. Where is Ink, Guardian of the Multiverse? How do these skeletons get along? (*SPOILERS FOR UNDERTALE*) (Rated T to be safe, maybe M) First part in my Undercross series. EDIT: Finally thought of a name and I drew the cover :D

"After getting drunk at a bar and stumbling your way back to the skelebros house, Sans insists that you spend the night. You wake up the next morning beside the monster you had always admired, and temptation gets the better of both of you." Frisk x Sans, Reader x Sans. No defined pronouns are used, but character is female. Rated M for jumping a skeleton's bones.

It's been years since the seal had broken in the Underground. Frisk has gone to pursue her own career in high school, but what happens when Frisk's old monster friends enroll with her into high school? High school AU, Sans x Frisk

Nineteen-year-old Frisk has led a happy, safe life after breaking the Seal that has hindered the Underground for so many years. But now, she faces a new struggle...a crush. And she has no idea how to go about dealing with it. (Sans/Frisk. Fluffy, sexy, with some occasional plot sprinkles thrown in. Hope you enjoy!)

Sans and Frisk have a midnight talk about the SAVE. Sans is unhappy. This kid is lucky he loves them so much. (A side-fic that takes place during chapter 13 of my story "Frisk" Pt. 5 of my Dreams of the Past and Present series) (Cover Art courtesy of dogpu on tumblr!)

It's Frisk's birthday and it's time for some fun! (We now know about Sans's past...but what about Frisk's? As Asriel asked: why did Frisk climb Mt. Ebott? Well, they have their own reasons.) (Queerplatonic Sans/Frisk. Trigger warnings of emotional abuse. Rated T just in case. Part 4 of my Undertale Series but can be read alone if you want.) (Cover Art courtesy of dogpu on tumblr!)
