Frisk has been in the underground for a few years now, she (yes I made Frisk a she if you don't like it don't read it) is about 17, her age will change through out. Sans is in his 20's. Frisk is a bit frisky in this story...but not just with Sans. This will contain adult themes and language. Enjoy it you filthy sinners ;-) **Formalities**This is an Undertale fan fic. I you don't support sans x frisk don't read it. I do not own any art, or characters. They are owned by Toby Fox and more talents artist. (I will link if I use art). http://weheartit.com/entry/231200067 this is where I got the cover photo.
