AU. In which you, the unsuspecting player, come across a peculiar game while searching your brother's room. Out of curiosity and boredom, you decide to play it. (a universe in which UnderTale the game is a real-life creepypasta)

A growing collection of drabbles and prompt responses cross-posted from my tumblr. The majority of these feature Sans and/or Papyrus from Undertale, Underswap, Underfell, or my own version of Swapfell. Most of them are also reader insert pieces (with a few OCs and self inserts in there as well...) Fluff, romance, and angst included. Most pieces are self-contained. Enjoy!
