Sans is caught in a terrible blizzard, half starved and running out of power, he resolves himself to do whatever it takes to keep his baby brother safe. Art belongs to Kamilecn on tumblr!

Frisk has saved monsters from the underground, but she may find more then just friendship among a certain skeleton.

"I have sinned..." And that's exactly why he was here. He has sinned more times than he can count, and they've finally caught up to him. The cuffs were clamped around his wrists as he was stuffed inside the police car and taken to the station. He had really done it this time, but he just chuckled in the faces of the officers. Oh, how he hated humans, not that he was much better. He was a violent, impulsive man with a quick temper and a long criminal record. He was told that grace would find him one day, and he would learn from them. Justice would come swift and accurate upon him, so cruel in being so kind to shatter his soul just to rebuild it again. He didn't deserve mercy, and that was fine by him. He was a criminal, after all. He would just take it.

Pretty much all smut... Yes...another one... This is just another frisk x sans Enjoy!!!

Frisk managed to fall down a mountain, find some scary ass monsters, and now she will have to fight for her life. But hasn't she done this all before? This story will have cursing and sexual scenes. So this is 18+. Another Frans story. Toby fox created undertale, I own nothing. Underfell is not mine whatsoever. [Cover art has been changed to an absolutely beautiful pic of fellsans and frisk! It was made by a wonderfully talented artist on Tumblr by the name of kamilecn. You should definitely go check out her Tumblr if you have the time!]

Being edited as of 10/20/19. Sans has a hard time accepting his feelings for a certain, grown up human and his whole world is turned upside down in just one night. The beautiful cover art was made by Blitzxir! You should go check out their stories too, they make good Frans books! I do not own undertale, the game and it's characters are all made by Toby Fox.

I hope you enjoy it.

Frisk always had a crush on Sans ever since they had left the underground. After she turned eighteen, she fantasized him of fucking her.
