Summary
He initially thought it would’ve much harder to wake up himself without waking Sans, but he hadn’t counted on a key difference between them. They were both heavy sleepers by nature, but… Sans had grown up in a universe that was safe. Where he’d never had to startle awake at night to defend himself and his bro lest they die to the exp hunters. That simple fact gave Red an edge. He was awake. Sans slept.
Perfect.

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.”

Summary
(Horror) Sans enjoyed watching you and his brother together. Whether it was cooking, working in the garden, or just generally enjoying one another's company.
What he hadn't expected was to enjoy watching you two more closely, when you thought no one was looking. When you assumed you were alone.
When you were more intimate.
