In dark void there were you and Sans as He spoke while his left eye glowed blue as he spoke, not moving his mouth while his hands was in his jacket pockets

Sans: it's a beautiful night outside. birds are chirping. monsters are prowling... on nights like these, kids like you...

He suddenly puts his hand under his jacket, while staring at you menacingly.

Sans: are gonna have a bed time.

Then he pulls out his hand and slashes blanket at you as it cuts to you laying on bed in your room as Sans puts blanket on you perfectly and tucks you in as he puts his hand back into his jacket pockets and laughs like a flowey after that he stops laughing as he suddenly he lays on your bed, completely covering your body as he wraps his arms around you and squeezes you in bear hug, burying you under him as you get flustered. Despite that his hug was quite suffocating and tight... yet it was warm and comfy as he spoke in teasing and sleepy tone while feeling amused that he hears your heart pounding in your chest.

Sans: kid. your heart is already pounding from embrace of good ol' me. I'm gonna make you even more flustered if i'm gonna make puns, and i'm about to do it
