Summary
Sans’ machine brings alternate versions of himself and his brother to their universe in a one-in-a-million chance. Unfortunately, you get flung into the madness when your soul is used as a conduit for the machine. Your soul cannot take the strain, and it inevitably snaps. A month later, while Sans is testing the machine, the machine uses the power of all of the monster souls in the house to bring you to this universe. Trapped in a different universe with a broken soul, you attempt to keep your secrets bottled up. Little do you know; your skeletal roommates have many secrets of their own. Pulled away from everything you’ve ever known, unable to use magic, and your soul broken, you find yourself questioning if all of this will just keep getting worse.

Summary
I'm just gonna say this right off the top - I am not entirely sure where I'm going with this fic but if you like fLUFF AND SKELETONS YOu are in the right story!! >w>
Uhm I suppose this is a very domestic plot with the whole "monsters living with humans but human don't like 'em" thing, also you are a little bundle of insecurity and anxiety who doesn't have a lot of friends and is just trying to make it through the day ;v;
Enojy!?

Summary
When you trust people to easily it is often missed that the people you put your faith in are holding daggers aimed towards you. That's why when I was betrayed by my best friend and was killed for a lie I vowed that If I got a second chance I would do everything I could to pay her back. Now when I thought that I didn't expect to actually be brought back. Nor did I expect the tsunami of trouble that would follow me from my actions and the actions of others... and what the hell is this steampunk knock off bullshit place!?
All I want is my revenge not stuck dealing with their bullshit. Is that to much to ask for?

Rainbow Dimension by TheGreatTigerGoddess for Frothy_Frowns
Fandoms: Undertale (Video Game)
18 Oct 2020
Tags
Summary
Inspired work of Frothy_Frowns story Don't Dimension It.
My take on the story but with a ton of steamy and sexy bit for all the people who like drama and sexy stuff.You the Reader had been adopted by your awesome gay monster dads years ago but now its time for you to go to college. They don't obviously want you to move to Ebott City alone so they just so happen to buy the house next to you! And a good thing to because it just so happens that there's a house full of skeletons from another dimension that want to get into your pants the moment they find out you live on the same street! Also there's 16 of them!! Kiss your butt goodbye cus they all coming for it.

Summary
Lust Sans has never been very proud of his AU which is often harshly judged by his fellow San's & Papyrus's. Finally they've reached the happy ending and no more resets, but what excites him even more is now that there's no longer a need for the 'heat injections' he can ask Grillby to officially be his date-mate! Unfortunately it doesn't go as planned and Sans is heartbroken.
Papyrus and the others convince Sans to come join them at Muffet's new Club/Restaurant named 'Sweets & Treats'. There Sans meets an attractive human male server who offers to be his friend, everything seems like it's looking up but there is something strange about this human...why does he smell like a female?
(I feel like Underlust is a bit under apricated because of its content, the idea that other AU's look at it differently to is kind of sad. The MC is an original character I created inspired partly by my character in Violentale. There will be a lot of various sexual and potentially triggering content I will try to mark chapters with a * if there is intense sexual content or possibly triggering material in the chapter.)
ENJOY~
