    When Papyrus starts going on dates Sans finds himself very uncomfortable with the idea of Papyrus being in a romantic relationship with anyone. "Am I just being over protective?" He's so troubled he asks friends for help and then starts questioning himself and his feelings toward Papyrus He gets an idea when he notices Papyrus's mailbox, which was always empty... "Oh this was bad..." "I should have never wrote that damn letter...I'm the worst!" "And now look what I have done to you..." Papyrus X Sans if you don't support Fontcest you don't have to read it...

    Honey, un pobre tipo al que la vida no le ha prestado bastante atención. Red, otro pobre imbécil al que la vida nunca le ha prestado atención. Los polos opuestos se atraen, más lo que los une es una fuerza de la misma magnitud. Un dolor compartido que cicatrizará ambas heridas por recuerdos del pasado. |>Apodos<| Honey: Swap!Papyrus Red: Fell!Sans Edge: Fell!Papyrus Blue: Swap!Sans »»»»»»»»»»»»»»»» Créditos: ©Ilustración por dupsmj9610 https://www.deviantart.com/dupsmj9610 ©Undertale - TobyFox ©Fell!Sans y Swap!Papyrus pertenecen a la comunidad de Universos Alternos de Undertale

    papyrus made an anonymous blog for dealing with his impulsiveness and insecurities but he has never been the best at hiding things from his brother ... specially when HE is the reason why he feels like this ⭐ a fluff mostly sfw story ! short to medium length chapters, everything depends on how papyrus is feeling ;3 CONTENT WARNINGS : this contains themes related to anxiety, suicidal thoughts, slight gore mention and obviously 1nc3st. please do not read if you feel uncomfy / triggered by any of these themes, thank you !!! (quizás lo pase al español si me lo piden 😳)

    Warnings: Sans x Papyrus SLIGHT/IMPLIED NSFW. The book itself will have some angst, but I'll put trigger warnings if you are sensitive to them. If you don't like this ship, then leave. I'll do what I want. Keep your opinions to yourself. -- A bunch of scenarios Sans and Papyrus go through! Ill only do classic for this book, and maybe I'll do other alternate pairings. But for now, this is what I'm going to be taking care of. -- I do requests.

    *None of the art in this book are mine* This is my first "Person x Person" fanfic so please be patient with me (^////^) This is Fontcest so if you don't like that, you don't have to read it. And if you're being dared to read it, then I am truly sorry. There will be no lemon/smut (I can't tell the difference). There might not be any "sexual-ness"? Like the smut. But if there is, it WILL be horrible. That's a warning! I couldn't think of a very good plot, so this is basically just Sans living a life of his sins. For his brother. You know. Yeah. So I hope you enjoy this story! WOooOOOoOoOooOOoOo now enough description-ing and LET'S START READING AND/OR WRITING!!!!!

    Fontcest! (Warning Smut!) If you don't like fontcest then you shouldn't read this. In this sans is a merchant and he and papyrus get down and dirty. ( Sorry I suck at descriptions)(also this the story and pic isn't mine and if the original creaters want their credit tell me and I will gladly give it.)

    Desesperación, siempre es relacionado con perder la esperanza, pero no es sólo eso. Aunque, no vamos a hablar sobre la definición etimológica de la palabra "Desesperación", nosotros sólo vamos a... Disfrutarla. Seis Universos Alternos en un sólo lugar obligados a participar en un juego de asesinato mutuo, nadie de ellos tiene poderes, sólo son monstruos comunes y corrientes que deberán encontrar la forma de no caer en la tan aclamada desesperación y sobrevivir. ¿Podrán sobrevivir a este maldito juego? ¿Se podrá confiar en aquellos que están a su alrededor? Y más importante: ¿Encontraran a la mente maestra de todo esto? Nadie está a salvo de eso, ni el creador, ni el destructor, ni nadie... +Under Ronpa (¿Tal vez este sea el nacimiento de un nuevo AU?) +Undertale by: Toby Fox +Image Cover by Me [credit to all of those images used in there]
