    Summary

    The Fell brothers are on the surface and out of the hellhole they call home. Edge has a good job and friends and hobbies. Red is still the piece of shit he's always been, but now he has Sans, who despite his best efforts to hide it is the best thing that ever happened to him.

    If Red would stop making excuses and allow himself something good for once, he could actually be happy for the first time in his life. But maybe he's right that everything is temporary. After all, in a world where there's still an undeniable tension between monsters and humans and everything can reset at any time, is it even worth getting attached? Is being happy, even just for a little while, worth the pain that comes with it if everything he loves is lost?

    Summary

    Papyrus is sick of Sans treating him like a child, and (Y/n) is tired of being who everyone expects her to be. When these two find each other they both immediately hit it off, but will Sans or her family try to interfere in their good times? Probably good thing the Great Papyrus is good at sneaking out and (Y/n) is bold enough to be herself! This story is completely self-indulgent and purely smut based plot (its barely there), but if you wanna come along on the journey of Papyrus getting to say fuck and be an adult strap on in friend.

    Summary

    What if Sans hadn't been home when your spell finally broke? Would you have gotten that kiss after all? And maybe... a little more? Or maybe a lot more...

    This is an alternate end to my previous fic, Good Girl Needs Kiss, where this time, Sans isn't around to interrupt you and Papyrus. This is pure smut, for all those wanting reader to finally get that kiss.

    Summary

    At the bottom of the porch stairs, propped against the railing, Dream glared somberly at the boxes as he finished off the tea that Ink had brought him earlier that day. It would probably take him two trips to get them up the stairs, but once he was done, he was done. He could start unpacking in the morning, and start new.

    “you lost?”

    Summary

    In a Multiverse where Ink and Error retire together after falling in love. Dream is now the new leader of the Star Sans and protector of the multiverse.

    With Error no longer a threat, Dream focuses his effort in pacifying the other big threat to the multiverse, his brother Nightmare. In an attempt to cure his brother of his curse of negativity, Dream uses a rather volatile serum from a rather lewd AU.

    How will this series of events play out? And how will the multiverse fair without Ink and Error?

    Summary

    Would you like to reset or continue?

    The yellow and black buttons appeared, glowing slightly in the darkness. Her body ached longingly. She didn’t want to continue, she wanted to go home, to see her friends again, and to see him. The smell of iron filled her nose as she looked past her body into the golden room they were in. The pillars lining the room were stained with blood, and there were jagged bones sticking out of the floors. The once beautiful stained glass windows now had holes in them. The room she once loved to sit in had now become the root of her fears. It pained her to fight, she never wanted any of this; she never should have listened to that stupid flower. Then she remembered what he, her best friend in all the time lines, had said,
    “If you're really my friend, you wont come back.”

    Summary

    Sans, Papyrus and their Pet had settled into a nice life underground, despite the Queens harassment and the bleak outlook all monsters had on life. They were in a world they knew how to navigate, one they held rank and power in. Not safe but safe enough. It wasn't the worst life to live while they waited for the last soul to get out of this hellhole.

    The universe has a funny way of granting wishes, doesn't it?

    “hey there, sweetheart, names red, nice to meet ya.” He took a lock of your hair in his slightly clawed hand and brought it to his nose, his eyes slid shut softly as he inhaled.You smelled like mint, peaches, human alcohol, and oh.
