Summary
Sans is exhausted. He is lonely, hurting, and only two steps away from Falling Down.
Underfell's first ever Gyftmas is approaching and Red is scrambling. He wants to get his brother the best present ever to celebrate, something that goes across resets with them.
A visit to Undertale provides him with an idea. It's morally wrong, completely unethical, and likely illegal.
Luckily for Red, he never really had a moral code.
MIND THE TAGS.
This story will get DARK. If anything, literally ANYTHING, looks triggering to you, please don't read this.On a brighter note, this is my first time writing smut! Please feel free to give me tips or tell me how I did!
I also accept ideas for things to happen in the story.

Summary
Sans wasn't able recall where he came from or what his childhood was like, but it didn't matter. Papyrus, his little brother, was his world and meant everything to him. Sans had been taking care of Papyrus on his own for two years, since he was 15. It's all Sans had ever known, which didn't say a whole lot. One day, his simple, pleasant world is shattered by a monster who takes his brother and is determined to bring up a past that Sans does not remember.
Will it be more than what Sans can handle?

Summary
“Tell me, Doctor… you have served me longer than any other. In what ways would you serve me?”
Feeling as if he were in a dream, Gaster numbly signed, <I would serve you in any way you ask, Your Majesty.>
The King raised a brow. “In… any way I ask…?”
Flushing deeper, Gaster signed, <I belong to you. My body, my soul, is yours.>
His Majesty’s eyes blew wide, then, and his breathing grew heavier. “...You will follow Rudy’s every order,” he managed gruffly. “If at any point you wish to stop what is happening, snap your fingers twice.”
