Underfell - Fellcest Fanfiction

It all started like any other day Sans sleeping in and being yelled at by his younger brother it always ended up with them both going to work, it was all normal until the end of their work shifts, Papyrus had gone to go get Sans who probably would've been asleep or waiting for Papyrus to get him, but upon further examination Sans wasn't at his station, wasn't there sleeping or waiting Sans just wasn't there this sent a chill down Papyrus' spine, Sans was usually at his station, so why wasn't he there? Suddenly there was a loud cry of pain, no not any old plain cry of pain, Papyrus recognized the owner of the voice that cried out it was Sans!

I might have went a little over bord with the description but its meant to be a small taster/teaser, this is probably going to have more fluff than lemon anyways, enjoy!
