This is my first story! So uhm...yea! It will include underfell sans and undertale sans! It will take place in underfell, with no other characters from undertale except for sans and frisk Frisk is gonna be a girl in this version and her age is old ages are: sans: 17 frisk:16 sooooooooooooooooooooooooooooooooo yea no lemons are gonna be here.

Sans and Frisk make it to the surface. Going back for the last look of the place they were trapped for a long time Sans try's to teleport them to Grillby's. Something goes horribly wrong! Sand and Frisk jumped in to another world. Trying to figure out where they are they run in to Underfell Sans. What will Sans and Frisk have to do to get back to there reality?

Reader is a little mentally unstable so you are sent to a high school for the gifted and talented which just has to be the only high school enrolling monsters at the moment but monsters have been underground so long they have to learn all the new things right? Right?? Takes place around the end of the school year and it's your senior year.

So...my first book. YAAAAAY...god I'm gonna screw this up. Heheh! ANYWAYS, hope you enjoy this! This is based off my OTP and the game Undertale. If you do not enjoy Sans X Frisk, then do not read it. Don't post mean and totally irrelevant comments. If you don't like, then just don't bother reading my stupid obsession! >:3 NOW THAT THATS OUTTA THE WAY, LETS BEGIN! NGHAAAAAAAAAAA!!!

In another time line. Another AU. Through Undertale history. This is a somewhat new story. That is about to be unraveled. Heh. sUCK IT UT SANS. MM. SO GOOD.

What did I get into... You've fallen into the underground but it's filled with sex crazed monsters will you ever be able to get back home again or will he catch you and keep you forever? Update I FINALLY FINISHED IT GUYS HOLY CRAP 7/2/18

I so sorry and I will never post the undertale lemons
