Soon enough they fall in love, but (Let's be honest here its not really a story without a little drama...) they soon get separated. Will they come back to their loved one? Or will they eventually forget about eachother??? Read to find out. (Or not I can't really control you XD) I hope you guys enjoy this story 💙❤ #14 in Kustard (Lol XD I only put this because Skeppy memes)

Dom! Fell x Sub! Sans - The description ^ says everything

after classic and fell met and became friends they had a secret love for each other. When they had their first kiss, fell went a little to far as classic stopped him because he wasn't ready. But fell couldn't hold back "the erge" any longer.

Kustard... Wowowee I'll do a dussic When Im Half way done...Yeah sure!! But Yeah ------------- "..." "..." Have no idea what to say...

Ink accedently opens a portal in Underfell and but dosn't notices it Red the unlucky skeleton falls into it right into UNDERTALE who knows what will happen while red is in Undertale

Sans and Red are roommates- that is, until Red wants to move due to Sans' shenanigans and mischievous pullings. Sans is struck with the realization that he doesn't want to see him go. A story about friends, pining, playful nicknames and a big fat crush that seems to get in the way.

Classic has been seeing his friends die, over and over again. The human keeps on resetting. In one reset, it all goes wrong. He ends up in a whole new place than he was. The place looks the same just edgier. He finds someone that looks like him and his brother, just edgy. Classic's life changes completely. But soon, he has to go.

this is my frist stroy,this was suggested by my friend and this is also my frist time writing a romance stroy....so PLEASE don't judge me!

Fell has a big secret. the back of his closest is filled with red, frilly dresses and he seems to flinch when someone uses male pronouns towards him. Fell is transgender. He secretly calls himself 'Cherry' in secret. He has the biggest crush ever on classic Sans, and is shocked to one day find,that his crush,loves him back. A little to much.
