Underswap!Sans x Reader

When I have that one dose of inspiration to make a sans x reader, it's going to wind up here. Have fun with fluffy fluff stories, and I will accept suggestions, as long as they aren't lemons, or smut etc.
It could literally be ANY AU sans x reader story! I like a good challenge, and even to improve my writing skills.
So have fun reading this hodgepodge of mini stories!
