The Woman of My Dreams (Sans x Toriel)
After Frisk broke the barrier and freed all monsters, life has been hard for humans to cope with their new friends. But even if life is hard trying to suit their new lifestyle, everyone will stick together as long as they have the boss monsters sticking around. Ever since Frisk became the ambassador of monsters he has been excruciatingly trying to get the word out that monsters do no harm. But after a few weeks on the surface, two monsters have feelings for each other. They both can't express their feelings, but it's only a matter of time until they fall in love with each other and start a new life together. A life they won't forget.

Kind Of Comical [Sans X Reader]
//Undertale High School AU. Your typical High School story where you're the new girl~ //Except monsters and humans are together too. Involves time travel in later chapters. Never wrote an Reader insert before, so spare me! "You look lost there, Kiddo." A deep smooth voice caught your attention and you turned your head, facing a short Skeleton in a fluffy blue winter jacket. "Oh, U-Uh, Yes." You stammered, looking down at your shoes. "Don't need to be shy." He chuckled lightly. "I'll show you around."
