    You and Sans both sleep in for the day and you're struggling to get up while he's ready to go. Sans tries his best to get you up for the day but it ends in a cheesy lovey-dovey love confession all over again, even though you have been together for 6 years now. Not that Sans didn't like it, he won't verbally admit that he's touched though. A hefty ton of fluff between Sans and the reader! Written in 2nd person's point of view. *Sans in this fic is heavily implied to be Gaster!Sans/Echotale Sans, but you can switch out his nicknames for it to be any AU Sans. * Sans/Gaster!Sans does not belong to me! All rights reserved, I only write for fun :) Covert art by elicitsins on tumblr.

    In school, there are different types of students. The Popular and the Normies. The Nerds and Jocks. The Magical and the Unmagical. The Bullies and the Targets The Sluts and the Innocents. The Handsome\ beautiful and the Ugly. The Weak and the Strong. The Determined and Lazy. The Rich and the Poor. The Talented and the Untalented. The Singles and the Couples. The Talkative and the Quiet type. There is a small bullied all her life. All because she works in a strip club in a young age. They didn't know her secret why she actually works there. They mostly call her slut....and mostly because of her name. But what if she had enough? ***************************************** "All of you will regret what you said. I will return. I will have my revenge. All of you will pay." She smirked evilly, tears running down her cheeks. She wiped her tears. Watching the street, looking at the window while the bus she ride is driving. "Goodbye memories, hello Change." We always have pain In the pain, we learn. Learning to pretend to be happy and okay. It makes you gloom Shutting yourself in a room. Suffering alone Crushing your bone. Your heart sinking Without even thinking. Don't worry I will be alright. The people that hate me Will open their eyes in reality. Because they will see The Change in me. ***************************************** Oooooohhhhh!!! How was the poem. I wrote it that's why it is bad. Anyway I guess you know who is this. If you don't know who she is then it is.............. Lust boi!- I mean girl. Yep, you red that right my starlings. Lust is a girl. All of them are humans.....with powers. Just a story made by me. No judging guys. This is just my idea, okay? All by me. So no comparing this is this and that is that. Please enjoy my stars!!! If you haven't checked out my CROSSMARE book, then read it please. This is all!!!!!!

    After the party, Blue and Lust started to hang out more. Meeting up every weekend or whenever they were free. It was incredibly obvious they fancied each other but both of them were too clueless to notice the feelings they reciprocated for each other. And here ladies, Gentlemen, and non-binarys is the slow-burn fic I always wanted to write. ~love Author

    (DISCLAIMER: THIS IS AN UNDERTALE AU) Allow me to describe this in the simplest way I can. There is a fanfic-like covering, but with a much darker, twisted undertone. Sanscest, if that's what you're for, but also a juicy amount of story with it. Enjoy!

    I read quite a lot of books like this so I decided to make one myself. There's quite a lot of mentions of... sex... but I'll refer to it as *it* cuz I don't like talking about such things. I mean I'm only 13. So I will always go somewhere else in the multiverse when they do *it* cuz of the reason I already mentioned. ~~~ Firstly, let's see what Blueberry's friends know about Blue. Blue disappears every week and comes back the next day, he says it's a "sleepover" but Stretch thinks it's something more to it (and he's not wrong) and gets suspicious of Blue. Blue doesn't tell them much, only that he visits a friend for a sleepover and they do fun stuff. Blue doesn't say who he goes to, where they hang out, what they do. Now, what Blue actually does. Blue goes to Underlust/Lusttale and hang out with lust. And they do *it* with each other. The reason? Blue is sick of being treated like an innocent child, this way he could prove that he isn't as innocent as people think. But Blueberry's worried about some things; that Lust would snitch (extremely unlikely but not impossible), his friends would stalk him, they would put a tracker on him and track him to Lust's universe, he would slip up and say what he does, someone else would find out and snitch to Blue's friends.
