Hello! This will contain everything from fluff to smut, if you want me to do other characters (like original sans, papyrus, etc.) Just comment and I will do my best to write them! I will also make sure to warn the readers when stuff starts to get mature. I wouldn't recommend people under 13 reading this, but it's your life. As always thank you for reading if you choose to!

I always wondered why exactly frisk did fall into the underground so this will be my own theory of the beforehand story that took place before Undertale. I will also write about the underground and the whole Undertale storyline, but I will be making it my own (like changing it here and there so it will not be like the actual game undertale). All ideas of undertale belong to the creator and this will be my own fanfic of the before the scenes. After that, because sans is my favorite, it will start to shift into a X reader. So I hope everyone enjoys my idea and thank you for reading! There might be semi-spoilers of the game undertale so read with caution everyone. The character that point of view is in, is Frisk's.

These will contain One shots, fluff, and maybe smut. It will contain mostly the original sans, but I may mix it up a little and do the other AU's of him. Thank you for reading if you do choose too! If you want to recommend characters or story's for me just comment below and I would be happy to write them for you.
