sans izuku story izumomo I do not own any art unless I say otherwise they're here and they aren't giving up easily

Ink and the other sanses were just having their meeting when suddenly they were pulled in to a portal. When they woke up all of them were all tied up. They tried to use their powers but , it seems the one that captured them put magical hand-cuffes to block their magic. They looked around and saw a tall figure standing in the darkness. Who was the one thats standing in the dark? Who will save them? Where did they end up? Please read the story to answer these questions! The other sanses haven't met the original yet but they all heard of him. (Reminder: all of the sanses are in love with classic.)

Warnings: Sans x Papyrus SLIGHT/IMPLIED NSFW. The book itself will have some angst, but I'll put trigger warnings if you are sensitive to them. If you don't like this ship, then leave. I'll do what I want. Keep your opinions to yourself. -- A bunch of scenarios Sans and Papyrus go through! Ill only do classic for this book, and maybe I'll do other alternate pairings. But for now, this is what I'm going to be taking care of. -- I do requests.

Sans has been doing his job protecting Frisk, no one else except himself and Frisk know about Gaster and how he listens into everything Frisk does while talking. Eventually Gaster goes too far and it's up to Sans, Papyrus, and Frisk to figure out how to get rid of Doctor W.D. Gaster...
