Summary
Ink was infuriating. However —to his bad luck— It wasn't a wonder how Nightmare let him do whatever he wanted. Was it really weakness if the thing disarming him was love? When would Nightmare draw the line, if he ever tried?
or
Was it really a bribe if that wasn't the initial intention / he genuinely just wanted to have a taste of the good old arbor vitae?

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
You and Sans have spent the last five years toiling in the lab on your magnum opus: a looking glass into alternate timelines. But when you test it one late night in the lab, the impossible happens and you are taken into a world much more violent and crueler than your own. Needing to survive until you're rescued, you will have to use all your wits, charm, and determination to convince three paranoid skeletons you aren't insane or a spy. Good luck, doll.

Despite the spelling errors, it's a really brilliant fic. I really like everyone's characterizations and how real everyone feels.
It's good to see that thing's have cleared up in chapter 20- and that the house arrest is finally over... Really wondering what would happen next- especially now that Sans knows it wasn't all a lie.
Hoping for updates. Ch. 20

Summary
It was a nightmare for you before you finally left the mansion. Heather had them all wrapped around her finger and made your life hell. At least you finally got away.
Then three years later you see on the news- the mansion was used for monster trafficking. The darker parts of society in other countries were always looking to get their hands on a monster to study.
With the autonomy Sans was afforded by monster society, royal guards and police never suspected the mansion was where monsters were being kept imprisoned after being kidnapped. A bloody and violent escape attempt finally exposed the secret. Now all the monsters imprisoned are free, including the skeletons who were chained for two years.
You want nothing to do with it, but there was one skeleton you did care for- Mutt. His brother was dead and who knew what traumas he faced in the mansion. He helped you get on your feet when you left. He was there when you needed him and it was time to return the favor, regardless of who else you might meet...- Language:

Summary
It was Tav's birthday, and she was back in the Elfsong. But this time she was naked, tied to a bed with her legs spread, blindfolded, and she was almost trembling with excitement and arousal.
Birthday gangbang, female Tav with no description. She's had all the companions separately... now she wants them all at once. Entirely, unapologetically smut.

I am going to go make a 3d model of sans as a egg

Summary
Between two part-time jobs, coursework, and classes, you don’t have the time — or desire — to find a serious vanilla relationship. After a chance encounter with Mutt leads you down a path you had long since thought you had abandoned, could it be time to start considering more serious relationships?
A shameless reader-MC fic, where a misunderstanding at the fetish club where you work as a bartender leads to sexy shenanigans with everyone's favourite FellSwap brothers, FellSwap Grillby (and a few more monsters on the way).
-
Slow-build, former PWP that’s now filled with plot. FellSwap Papyrus (Mutt), FellSwap Sans (Milord), and FellSwap Grillby. Individual chapters are tagged with potentially triggering content. The primary focus is on safe, sane, consensual kink.

Summary
Sans did not remember his previous name, only that he had been human. Rebirth in Undertale was novel, but he adapted, until he realized that the universe he was in was not the original one.
Unfortunately, it was too late when the machine took him to another universe, into a room full of skeletons.
——————————————————————————————
Sans no recordaba su nombre anterior, solo haber sido un humano. Renacer en Undertale fue una novedad, pero se adaptó, hasta que cayó en cuenta de que el universo en el que estaba no era el original.Lamentablemente, ya era tarde cuando la máquina lo llevo a otro universo en un cuarto lleno de esqueletos.
Nota: Sé que suena como tragedia, pero en realidad es una historia bastante esponjosa de curación, o al menos eso intento. Nuestro protagonista tiene mucho trauma y lo va a sanar en una mansión llena de esqueletos incómodos
