Why, Hello Human! This book used to be..not as great as it is now! It's been a while and I have finally finished my puzzles. There's no way you can get through them now! Mweheheh! Author: Heheh-Hey, Guys! This book was awful back then. Just forget about those awful chapters in the beginning. The chapters now have improved. I hope. But, yeah. I'm still finishing this unholy book. Welp, See ya!

Ok, Ok, this is my first fanfic ever so please don't hate it if its crappy. I have been reading a whole lot of blueberry fics but none seemed complete in my book so that's what I'm going to attempt to do. Warning I love my lemons. I also have curse words in the story. *no longer updated*

You and US sans are going to do very lewd thing for the first time. But things get a little hotter with papy involved.

[Prolong] My name is (Y/N). I have experienced many resets, so many I have lost count. The only people who remember are Sans, Flowey, and me. The monsters down here are misunderstood, they are afraid. They kill me again and again. Even Sans kills me, actually he is the most ruthless. The only one who never did was Flowey. He is my best friend, we have been through so much together. He has taught me to fight, I never did though. I couldn't bring myself to, if I did I would be just like the other monsters. The most current timeline, I finally convinced all the monsters that they didn't need to kill or hurt each other. It was so hard. Sans was the hardest of them all, he...he was scared of moving forward, because he believed time would just turn back. So, what's the point? But! I had finally broken the barrier. I- no, We! We were happy!! ...but still time reset. Why?!?! ... But this reset was different. I wasn't in Underfell anymore. (Cover: By- Sanspar on Tumblr) [I own none of the artwork within the chapters]

The title says it all. Y/N and her sister grew up hearing the stories of the underground. One day, their imagination may have taken them too far... Note: Underswap does not belong to me credit goes to the creator.
