Summary
Life moves on. With Nightmare in jail and his gang free to live their lives, they have to find ways to occupy their time. Either with finding love or starting families or discovering things about themselves they’d long since forgotten. The trauma will never leave and there will always be setbacks on their journeys, yet life moves on.
(The second part to my story Uncut Quartz and Glimmering Pyrite. I’d recommend reading that first, but it’s not required.)

Summary
Hello, my name is Mazy, now that you will be a reader soon, you are known as a Mazyville, I'm nonbinary and go by they/them. My favorite fandom is Undertale and its alternative universes. I write semi-literate so all can understand well. English isn't my first language, though, so don't be too bitter.
I'm not a new writer, but I've never written on AO3 before. I'll be taking requests for any fanfiction Idea you have, not a short, but I'll make a not-so-long story about it. Just comment with your main idea or a summary of what you want your story to be, it can be ANYthing and ANY ship.
READ THE REST OF IT TO FIND OUT MORE!! AND READ THE NOTES!!!

Summary
Peace was a word Killer only heard in dreams. But now that he owned his own house with his loving partner, Cross, the realization hit him that he was truly free and had his whole life ahead of him. What’s next for them?
His attention drifts to the floating target above his chest and an idea bloomed. A way to show his devotion to Cross. It’s one of the few things that haven’t been taken from him. One of the few things he could give to Cross that he’d given to no one else.

Summary
You honestly can't remember when you had officially moved into the lodge to be with your datemate. It started as leaving things in his room under the (flimsy) excuse of having stuff for the next time you have an impromptu sleepover—but it was a not-so-subtle takeover.
The others didn't mind it either and were gracious enough to provide you with your own room for when everyone's shenanigans prove to be too much for you, but little did they know that they practically invited the devil herself into their home, because you're the queen of starting some bullshit or doing things for the bit.

Summary
Silly summary: Lust and Red play 7 minutes in heaven at a party. Except...it isn't 7 minutes, there was no pulling names out of a hat at random, and Lust is disassociating. Fun times ensue!
Not so silly summary: Lust is an outcast, ostracized by most monsters outside of his AU with very few exceptions, and even those exceptions were those that Lust never really considered his friends. One day he gets an invitation to a party, curtesy of Blue, so of course Lust makes his appearance. At the party, Lust finds none other than Red, a monster that though he finds him attractive, the Fell monster was a constant bully and instigator in his life since venturing out into the multiverse. Why Red does this to him? He'll have to learn the hard way.

Summary
You, an unstable bipolar bitch who can't hold a relationship or job, run into a box full of 3 1/2 little bittybones. You have your work cut out for you, will you end of rehabilitation these little dudes or will you be just as bad as their previous owner?
Heads up so you don't waste your time waiting to find out-
- Reader tops/doms 100% of the time
- Reader does not maliciously abuse the bitties, accidents just happen
- Kinda starts sexual at the very beginning, and this will be mainly kinky stuff
- Piss stuff but only for humiliation, no weird consumption of it
