Its been 10 years sense the magic barrier broke, and Frisk has settled down with their lovely human husband. But nothing goes exactly how everyone plans. 3 months into the pregnancy, their husband dies, leaving Frisk with her mother Toriel, and 6 months later, a baby is born, but not everything is as it seems. (reader is frisk's child, AU that toriel can see people's souls, Alpyus x Undyne, Papyrus x Mettaton, will add more later on )

Like the title says, it's gonna be sad. But there is a happy end to it I promise!

I'm skipping the ruins for starters, so you start out just as you exit the ruins. I plan on this being lemony pretty quick cause it's fell Sans come on. Story does develop... eventually. Plot structure and what not.

Sans and his brother, Papyrus, have lived life somewhat peacefully despite all the murders and hate rummaging through Snowdin. They've had an eye for each other since the beginning but choose to hide it to avoid problems. However that doesn't last when Papyrus suddenly snaps at him one day, sending his off into the world. Will Papyrus be able to find his brother and fix his mistakes? Or will his efforts to reconnect with his only one be in vein? (It would seem this became a book instead of a short story... Sorry.... ^_^""") Also any additional tags to expect: Mpreg Betrayal Near death/actual death Birth

You died. Again. But, when you woke up... You were back at the beginning. You didn't reset... but something was off. Flowey seemed skittish, frightened even. He was KIND. The people you knew, you once held dear... CHANGED. The entire underground was different... Dark. Nobody seemed to recognize you, but a part of them still remained. Someone who just wanted a friend, to be looked up to, respected... And another who just wanted hope-who was tired of this game... You're left with two choices: Will you kill to survive, or will you die befriending them all over again? Authors Note: This is in the AU Underfell. I recommend looking into it, it's simply amazing to me! Long story short, the "you" mentioned there is Frisk but it was a good description for the AU I found once. This is basically, somewhere the save file got corrupted, and now everything is reversed except Frisk. Hope you enjoy! Disclaimer: I do not own Undertale.

Underswap Sans x Papyrus EXTREME NSFW! (I do not own any pictures including the cover photo) Sans gets curious as to why Papyrus comes home drunk all the time, so he talks Papyrus into letting him try his whiskey. After waaaayy too many drinks, Papyrus manages to pry Sans away from Muffet's and back home to where Sans lets himself go. Having drank so much alcohol and for his first time makes him confused, vulnerable, and curious. Papyrus doesn't have as many shots, but he's still affected and has his own alcohol-induced fun time. After that one night stand with his brother, Papyrus realizes he's craving Sans' body and eventually can't control himself anymore. Again, this is NSFW, please be responsible and respectful.

There is not a enough Fellcest books!!!!!!!!!

Warning: this is a lemon Everyone wants this kind of Fontcest and I personally...like it, dont judge me ;-;
