    Summary

    “But first,” said Fell, “we need to lay down some rules.”
    Number one: No telling our brothers
    Number two: No sleeping in the same bed
    Number three: Absolutely NO getting attached

    Fell and Swap decide to embark on a casual relationship. No feelings. No attachment. Just sex. As long as they stick to the rules they should be fine… right?

    Summary

    /You stood there in shock, staring at the gunman. He had a blank look in his eyes. Like it was all routine. Like he was numb. You chuckled and choked on the blood building up in your lungs. It spit out of your mouth as you coughed and smiled at him, shakily bringing your hands up and clapping. Your chest throbbed. Your lungs burned as it drowned in blood from the open bullet wound.
    He stared at you blankly. His gun still pointed at you.
    You collapsed as everything went black.
    As everything disappeared./

    Summary

    Inspired by Bittybones (Actually I have not fully read the creator's concept but it sounds similar to this story's theme. They are small, they are pets, they are skeletons and they help people), I had to tweak the idea a whole lot because I can't say the Undertale characters are addicted to Sans and Papyrus skeletons... (There are OC units, but they are only mentioned.)

    Yeah, that's the only problem I had there... (o-o)

    Story focuses on POV of the Papyrus Units (No. This is Undertale Papyrus, Underswap and Underfell Papyrus) and how they work around their environment. They are also sibling units so... uh.

    This will branch out to something else. You don't need to read everything, just the basic information and names for the incoming story since I'm going to branch this like a vine.

    Summary

    Something unexpected has happened. The skeleton brothers from Swapfell arrive in the Underswap universe and Sans (Blue) makes it his mission to save Razz (Swapfell Sans) from his wicked (and abusive) ways or die trying! Probably the latter. Maybe he should settle for just getting him to treat Slim better? No! He will not give up! Everyone can be a good person if they just try, right?

    Summary

    Sans is nervous about telling anyone that he is pregnant. During his latest training session with Captain Alphys, others find out, but not in the way he'd have liked.

    This idea came from a venting session I had due to some IRL issues. This fic involves themes of death, despair, and possible thoughts of suicide. Please mind the tags. Thank you!

    Summary

    Eve Rhyden is a well-kept secret and is fiercely protective of her younger brother Kenji. The measures set in place to protect her have unfortunately caused her to be introverted and friendless, but she's had it drilled into her that her duty is more important than her own comfort. So how is it going to sit with her when monsters start popping up and try to butt into her locked up life? Lot's of fuckery and angst of course!
