Our little pet (a sans au's x classic sans story)

What is happening

"SANS" undyne yells
"What" I yell back clearly annoyed
"Someone or something has fallen down here so go help look for them!" She demanded
"Whatever" I say as I teleport to my sanctuary post

I see a figure walk past clearly confused. I walk behind them and I put out my hand

"Don't you know how to greet a new pal, shake my hand" I say like I use to

Sans pov:

I recognise the voice as fells and turn around quickly to shake his hand. He looks confused or weirded out. TIBIA honest I'm confused myself. I seem to be in frisks place and it's kinda strange.

"Hi again fell" I say blushing abit

Fell pov:

I sigh and pull sans close, making him go bright blue. I move his hair and see that a couple flowers have started growing on him just like the first frisk I met. My original frisk...

"You look tired" I say looking at sans
"I'm fine fell" sans replies as he skips off

I follow him so I can make sure he's safe. As I turn the corner I freeze.

"WHAT THE HELL BOSS" I yell tearing up
"What's the matter snas" he replies

My face darkens as I hold sans closely

"Heh I can't believe that I thought you changed" I say while putting sans on my back

Bosses face darkens but I really didn't care at the moment.
