    Summary

    Blue's been dealing with a lot while training for the royal guard. He was doing well up until an incident with his brother and two best friends...

    Now, he's abused, forced to do things he didn't even fully understand. All he knew was that it hurt. Bad. Sometimes, different monsters would be with his brother. He was too scared to complain or speak, to tell papyrus that it hurt. he just learned to take it.

    Three years without contact from Blue drove the Fell brothers to find out what happened to the precious ball of smiles and energy. But they weren't prepared for what they saw when they did find him.

    Summary

    "* You’re all Papyrus can feel and see… he kisses you back like his life depends on it.

     

    * Suddenly, you’re on his bed… he flips the two of you over and begins to kiss every inch of you over and over again, intermitting the short kisses with long, drawn out ones on the mouth that only end when you feel the need to gasp for breath.

     

    * In the end, Papyrus collapses over your chest, sobbing with relief."

     

    In which the author ruins the cute fluffiness of a couple of suggestion blogs because she has a sinful mind.

    (and in which stretch finally ruins a blueberry with sticky honey)

    Summary

    Hey everyone!

    I recently opened up my Tumblr for some requests. I was thinking maybe I'd get 1 or 2... but I'm still working through them. So this would be a constant WIP.

    Beware the story with rape/non-con elements: Alphys/Gaster, Fellcest, the ErrorInk at Ch. 24, the Edgeberry in Ch. 28. Please avoid if triggered or uncomfortable.

    Anyways, enjoy and please tell me what you think.
