Fontcest/sanscest (requests open!)

There will be lemons! There will be story!
When requesting make sure you give details about what will take place; do you want it to be a lemon/oneshot/fluff? Or do you want it to just be a sweet confession story? Where will it take place?
I don't know all the au's so make sure it's some of the main ones I know: Undertale
Underswap
Underfell
And the sans and paps I know:
Sans and papyrus
Blueberry/swap sans and swap papyrus
Fell/red/fell sans and fell papyrus
Dust sans
Nightmare sans and dream sans
Horror sans
Error sans and ink sans
Lust/lusty/lust sans and lust papyrus
Geno sans
Fresh sans
Cross sans
Dancetale/dance sans
And that all the ones I know.

And don't forget; REQUESTS ARE OPEN!
