(Toby Fox owns UnderTale, I plan to replace the cover with my own, and there needs to be more Sansgore like what the actual heck) After the surface was finally in the monsters grasps, they were so excited to move on and find new lives under the sun. However, Papyrus wants Sans to move on and get his own life and house. When Sans sees that Asgore too has no plans for the surface, he offers that they could be roommates in this small house. Asgore agrees. They're totally not gay for each other.

Art cover and other art isn't mine! I'll be doing oneshots. I'll do anything but r@pe, !nc3st, and things related. Note: AFTER "THE RUNAWAY", THERE WILL BE NO MORE FEMALE BLUE. Also, please no longer as for part 2's. It's called a ONE shot book for a reason 🥀. #1 in Bluemare on 9/10/25 #4 in Nightberry on 9/20/25 #5 in Sanscest on 9/18/25 #6 in Underswap on 7/12/25 #8 in Bluemoon on 9/10/25 #9 in Dreamtale on 8/28/25 #11 in Nightmare on 9/10/25

AU Sans X Reader Long OneShots by mylittlepinkamena222

Just Sans X Reader No Lemon Cover by my homeslice tkdgirl222 I don't own any of the characters in these story Don't kinkshame me I know your here for the same reason I wrote these >:) Also these are for girls but you can change the pronouns and the girly stuff to guy stuff I don't care. @tkdgirl222 edits and helps write all of the stories.

Our beloved Monsters live at the surface for almost a year now. As Christmas time begins, they are all overwhelmed by the festivity and happiness this time of the year brings to everyone. And monsters realize: it's been a long time since they celebrated a family festival under the stars. This is basically a small collection of one-shots that play in the same universe. It will work like an Advent calendar, which means there will (hopefully) be one chapter per day , until it's Christmas eve. Please understand that I am not a native English speaker, so if you find any grammatical errors or typos just point them out to me. I will gladly correct them and learn for the future.
