Sans X Frisk (An Undertale FF)

61 parts Complete

After Ethan (Frisk's older brother) broke the barrier and set everyone free, they went on a huge trip around the world to spend more time together. Frisk had no time at all to talk to her friends and to top it all off she had lost her phone on the first plane ride. Her and Ethan decide it's a good idea to go back to where all of her friends live after over a year of traveling. Frisk was so excited to see her friends again. Especially Sans. Before she left they shared their first kiss and she said that they could work out a long distance relationship but it didn't work out since she had no way of talking to him. She just hopes that they can become closer after not seeing him for what felt like forever. Most of this story will be in Frisk's POV but I might change it around sometimes. Frisk and Sans are about the same age and Frisk is a girl. Chara will be in this sometimes but she's not a genocidal maniac. Also Asriel is in this as well and Flowey was never a thing. One more thing. This will have some curses in it so if you don't like that, don't read it. Anyways, enjoy!
