Undertum Stories

your baker mother Muffet, your chubby you, and big "bad" Betty, all in one story that ends well! (art belongs to really-normal)

Mainly what the title says. Lots of Sans, ton of SANS, Undertale sans, undefell sans, ALL THE SANS. BUT WITH A CHUBBY READER. WHHHAAAAT I KNOOOOW. READ FOR THE FLUFF THE CUTE FLUFF. (BUT IF YOU WANT SOME LEMONS HONEY, YOU GONNA HAVE TO WAIT TILL I GET THOSE IN ANOTHER BOOK. ;) ) Also, there will be a request chapter, I won't take all requests, but I will take some. ALSO CAN I JUST THANK YOU GUYS FOR 23k?!! LIKE WHAT?!! (Tbh if we get to 25k I might just continue that little one shot y'all keep requesting for me to continue to there's that.)

Frisk has grown up now and moved away to the big city to attend college. She misses her monster family, especially Sans. He comes to visit her one day and suddenly, something new blossoms between them and the two discover something they both enjoy. note: the cover is a place holder lmao weight gain | willing | feeder/feedee | cishet | frans

Toriel stuffs frisk

..... i made a wattpad account for this....Merry Christmas...

it has fontcest but only slight 18+

I just put some undertum storys I thought of in here, it's that simple. I hope you enjoy this book though.

Toriel gets lonely, wishing the humans didn't leave her so she eats herself into obesity.

I just found out this was a thing and I have done a lot of research for this so now I can write a fanfic!!!!

I've noticed a lack in Undertum and Inflation stories, so here's a collection I will work on every once in awhile! From inflation to weight gain! Edit: I'm probably going to focus all the tummy love towards male characters, I find that there are so many female stuffing/inflation fics that I want to give the bois some love too! That doesn't mean that females cant be feeders/inflators, but I want all the belly action to be centered around the male characters...

an nightmare sans undertum story,(horror x nightmare)

Betty spends the weekend with Toriel and learns that trying to murder Frisk isn't needed for a happy mind and that a sweet alternative is coming (cover belongs to NommersU)

After so many meals and so long of being fattened up.... this is the only way it could end

A small little place for Rping weight gain. (Credit to Chub-Love-Fics on DeviantArt for cover.)
