Hey guys Firefox here! And I know how much of a flop attempting to write a fanfic was a couple months ago but I feel like I'm ready to try again. Plus there aren't many fanfics about these two and its my Undertale OTP aside from Charisk so... I'm gonna try this out!

Determination - G!SansxFrisk by Toasty-Writer

Frisk just wants to save monster and humankind, but does she have the determination to do everything she wants? Especially as she has now been blamed for the terrible crimes committed by her sister. G has stopped caring, but can this infuriating woman who becomes his neighbour pull him back into the world and seek for justice again. I'm so bad at descriptions :/ I'm delving headfirst into fanfiction. You guys may not like this story or even read it but I'm going to try. This is a Gsans and frisk story, there will be an attraction between them but it may be slow :P I do not own the characters or their respective AU's. I'm simply throwing my own twist into the mix hoping you like. I do not own any of the art featured in this book, they are just all amazing. Will involve some moderate language, violence and trigger warnings, hence the mature rating, I will warn at the beginning of chapter if there is a trigger warning.

He's Mine (COMPLETED)(Yandere Papyrus) by BubblyShip

(UnderTale rightfully belongs to the amazing Toby Fox, I am not creative enough to make that masterpiece. There is a person named symphysins who drew some work of Yandere UT! Papyrus for Sans, and I really liked the idea of a creepy UT! Papyrus and decided to write a short story on it. Also, Frisk can't reset, she never had that ability. The cover is my own art.) "Why is everyone I date dying?" Sans asked, covering his eye sockets. "Am I cursed or something?" "I'm sure you're not cursed, Brother!" Papyrus said, patting his back. "T-There might b-be a Yandere on t-the l-lose!" Alphys piped up. "A Yandere?" Sans asked, tilting his head. "What's a Yandere?" ~~~~~~ Sans felt like something was wrong. Everyone he tried to date ended up dusted, and he couldn't figure out why. So, when Alphys explains to him what a Yandere is, he realizes he might be someone's Senpai. Determined to stop this endless cycle, he teams up with his friends to try and find this psychopath. If only they knew he was closer than expected.

The life of the skelebros by lili_bugg

The young skelebros escape from the core and head to Snowdin. Grillby finds them decides to take them in but finds out it may be much more difficult than he thought. Papyrus likes Grillby but it takes Sans some time before fully trusting him and even then there are things that he doesn't want to share. Although Sans struggles with his magic and with meeting new monsters. But, he's able to find some close friends when situations get rough. Ik my art is kinda weird but it was mostly just for fun. I'm definitely no artist. All art is still mine tho. I won't edit much here. Fully edited story on Archive of Our Own. Same name as here.

From Darkness, Love Came Through by FinleyLivesInTheVoid

A long KingDings fic because this ship does not get the attention I think it deserves. I love this ship, and it's adorable. I plan on making this a full story, so buckle up! Also in this Gaster is Sans and Papyrus's father because Dadster is wholesome and cute. Toriel and Asgore are decent friends in this one because I believe that they could have a friendship if they tried. I will put in little bits of my other ships, but Asgore and Gaster are the main focus. If you want the actual story, read it. It's very fluffy and cute and gay. If you follow me, I know you like the gay ships.

Sans x reader (together) by Gabbylabby123

Hiya! This is going to be my first fan fiction. I have recently been obsessing over undertale, and sans is my favorite character. I have already read a lot of sans x reader and decided that's what I wanted to write. I don't know how long this story is gonna be or how often ill update, but ill see how it goes and if you guys like it I might do more in the future. XD wish me luck! Ps. I do NOT own any artwork that may be used.

(Sans x Reader) When Two Souls Meet by ZanaBSparrows

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister. Please note the the story is primarily on Quotev, so updates to Wattpad may be late, or lag behind that of Quotev. The story also has the potential to become mature. (I haven't decided yet.)

Dear Diary by Pervigeo

cover and possible art in the book isn't mine neither are the characters. I credit if I know/find the artist. I only own the storyline. No one knows when or why they appear but everyone has a special diary that's connected to your soulmate's. You can see what they wrote and vice versa. It might sound easy fore you can just tell your location to your mate but the diary doesn't share that kind of information. This is the story of Sans, Sans the Skeleton and how he found the love(s) of his life. Everything is in Sans's pov unless told otherwise I edit quite often but try to write new chapter weekly, I'm kinda irregular though.

Burn my frozen heart by TheeePunkin

Meet Maya, a wonderfully sarcastic girl with the ability to befriend sassy flowers, talking skeletons, ghosts & even a walking candle. Oh, she also has anmesia. Sounds like fun? Then buckle up, cause you're in for a ride full of sarcasm, banter, idiocy & of course love. Because what would a story be without love? And after all, Maya always had a thing for everything that burns. (it's better on the inside. Trust me. I wrote it xD) (it's also a GrillbyxOc, cause the fire boy needs more love) Highest rank: undertalestory - #1 Flowey - #1 Grillby - #1

Hot Stuff || BOOK ONE. by Flamogedeon

- Long story short: You climbed up a mountain, you fell into a hole, and you didn't bother going back to the surface. And why is that? Because of this hot stuff. - I'm pretty sure the cover says it all, don't you think? And I'm pretty damn sure that THIS is long overdue!! Aww, yeah, baby!! This fire-baby needs some love too, y'know? So without further a thou, I present to you, a Grillby x Reader book. *insert majestic exit* See ya. - EDIT: Quick Disclaimer, y'all. The photo used in this book ISN'T mine. No big shocker there. It belongs to its RIGHTFUL OWNER. Frankly speaking, I found the photo on WeHeartIt. Check it there if you want, I guess? Anyway, hopefully, I don't get sued by this. See ya.
