Summary
Betrayal and deception are the order of the day in the state of Undertail, located in the Underverse. A state where there are small rural towns of poor people and cities with rich or middle-class people, but in this story, we're going to focus on the tale of a particularly imbecilic group of idiots, who will suffer on hands of the rich:
King Ganz of UnderToes
The Lord twins of DreamTale.
The Unknown King of Underverse, Cross.and the worst of all...
Landlord of the nine mud pots, Ink Comyet of Underverse.
+++++
Just to clarify, I'll be adding tags as the story goes on, but I think I already added the important ones, most of the new added tags may be from characters; there will be no gorey violence, just dumb silly violence treated as serious, no explicit sexual content because I don't find it that interesting to write, and I think that's it.I'll be updating whenever I feel inspired or I have time, because I'm soon to go back to college and I may not have much time anymore, therefore, if I DO update, it may be short, I just wanted to clarify that so you guys don't feel too annoyed at the wait for a short chapter.

There's quite a few non-con one offs posted here. But not all of them are non con!
If you don't like non-con, be careful! I'll try to have warnings at the beginnings of each chapter!
Hope you enjoy ♡ -

I hope you'll like these little stories!
