    Summary

    After being strong armed into a double date, Swapfell and Underswap Papyrus have to play along, not knowing what exactly their brothers have in store for them...

    Oh, and they have to keep the fact that they just banged 3 hours ago a secret from everyone too. No pressure.

    Summary

    Four years ago, Blue might have greeted a truly awful day with a smile, maybe a loud proclamation of his own greatness. It’d seemed almost… simple. All he had to do was stay bubbly and bright, and the world would right itself. If he gave it some time, he would adjust. After all, he was loved, right? He was married, cared about by two of the most considerate monsters in the whole of four undergrounds. Even without the hope of that classic dream of a family, he’d thought… maybe he could be happy.

    He was beginning to learn that life didn’t quite work out the way he’d always thought it would.

    Summary

    You moved to Mount Ebott to escape your mother and her expectations. You expected for there to be nothing of interest there. So what if there are legends about monsters and missing children. Lots of mountains have missing people. Yet...

    You've been having these odd dreams lately. Each one lands you in a place where the sun never seems to set and an alien white light shines from the skies. You've accepted a task that has put you against sixteen monstrous creatures known as the Keilaises, large skeletal creatures made out of stone, earth, and magic. From each of these guardians, you must retrieve a shard in order to complete your quest.

    You don't know if these dreams are real or not. With your sleepwalking issue becoming more and more frequent, these dreams seem to be out of control.

    ...What's this you say?

    You're saying that monsters have come down from the summit of Mount Ebott?

    ...Did your dream have something to do with this? Or are you just going crazy?

    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?

    You're a recently awakened human mage who has been forced to sign up under the Mage Registration Act and court-mandated to seek tutelage for your dangerous and out-of-control magic powers.

You struggle to keep your jobs, your powers, and your heart under control, but shenanigans ensue. Because you're dealing with skeletons.

    Summary

    (New Summary)

    Undertale? Of course, you’ve heard of it. Who hasn’t heard of that popular video game? You’ve read more fanfics for that game than you can count. You never once considered that it was more than just a game, though. It’s not until you suddenly wake up in the world of Undertale that you realize that the characters are actually real. Amazing as this is, you can’t help but be concerned about how you got there. One minute you're walking to class, and the next you're waking up in the snow. And, if appearing in Undertale wasn’t already a big enough shock, you keep AU jumping and ending up in different Undertale-based worlds! While you have no problem with meeting the different versions of everybody’s favorite skeletons, you quickly realize something weird is going on in each world you visit. Something that’s causing a lot of trouble and damage. Looks like you won’t be able to go home until you figure this mess out. Well, at least you get to befriend some cute skeletons along the way.

    Wait a minute! What the hell is wrong with your soul?!!

    Summary

    A night out with your roommates' sorority sounded like a good way to wind down from exams season, but your good intentions to keep from ruining someone's nice carpet have you end up in the middle of the forest. In the middle of the night. Very, very drunk.

    Good thing you found a random house to sidle up to and ask to use their phone. Less of a good thing that the skeleton monster that lives in it is only placated by your sloppy jokes.

    -

    Eventually going to culminate in a "Six Skeletons" sort of set-up, but you don't get off as easy by knowing Classic Sans first.

    Summary

    Razz, the heir of the Beobyrian Empire, is on his way home from a diplomatic mission as his ship gets attacked by pirates. Suddenly he finds himself taken as hostage, and it doesn't seem like the pirates are planning to exchange him for a ransom anytime soon.

    Summary

    Because I can't not keep starting new fics on here XD

    Inspired by this exchange on Tumblr (and by an actual dream I had), where Mutt from SSLL moves in to my place and pays his rent through doing work around my house. The flirty skeleton keeps making passes at his new landlord (narrated as you), but she's a bit more Determined than he'd counted on.

    Summary

    Undertale AU Garbage. LOVE, love, smut, angst, edginess, and self reflection. A story about teamwork and friendship, with lots of puns, ships, and feels. Full of head-canons what might deviate from the original story and/or AU ideas.

    Worlds collide when shortcuts resonate. Will they be able to find their way home?

    Summary

    It was a day like any other. Reading fanfiction, eating slightly overcooked ramen, questioning your existence, and listening to edgy nightcore variations of songs. Ya know the usual. Your parents were on a year long business trip leaving you home alone because reasons that will never be explained throughout the whole story. Shortly after going to bed after a long day of doing absolutely nothing, you hear something. You go downstairs to find… Skeletons in your home? What the fuck?! Oh god this is gonna be one of THOSE stories isn't it?!

    Summary

    This universe shouldn't exist, but it does. You shouldn't be in it, but you are. Life is just unpredictable like that, no matter how infuriating it can be.

    In a universe where monsters won the war, humans were hunted down and either killed or tamed. They were then split into the two classes of pets and workers. Workers do manual labour and pets are basically what they sound like. You've ended up here as a pet. Not by choice. Things happened and you ended up in an animal shelter where you've gained the attention of four short skeletons. You have no idea what they want from you, and you're definitely not sure you're ready, but life won't wait for you to be ready. It's time to see what they have in store for you.

    Summary

    A much abused Swapfell Papyrus trades places with the overly adorable Undertale Papyrus. While Swapfell Papyrus struggles to overcome his fears and insecurities, UT Papyrus' core belief is trying to doubt itself. Everyone can be a good person if they just try. Even this fallen Sans can be good . . . Right?

     

    If you can't tell, this is a Swapfell/Undertale Parody of "Trade All my Tomorrow's for one yesterday". I love the story, and can't get enough of it.
