The 6th Soul | Sans x Reader

C H A P T E R_20

[ Forest, Underground | 9:23 AM ]

You woke up with your head still in the warm jacket of Sans. Right, you were still in the middle of nowhere. You adjusted your long sleeve shirt and got up. Sans was still unconscious, so you figured you could try making a campfire of the remaining sticks you had.

Turns out, they had been buried under fresh snow, so you just had to keep yourselves warm with a single flame in the palm of your hand because you'd drained all of your magic the night before.

Sans groaned and opened his eye sockets slowly.

"Morning sunshine." You chuckled at the sight of the sleepy skeleton and sat down in the snow.

"Oh hya. Morning. You're looking smoking hot today." He grinned.

You blushed from his comment. "What can I say? I guess I'm just too hot to handle." You said nonchalantly and got up.

Sans got up as well and pinned you against the tree with his arms along your head. He pushed his teeth against your lips and slowly began rubbing your waist. You let out a gasp when something like a tongue slithed into your mouth. Whatever it was made you shiver when it explored your mouth and tangled with your tongue. You moaned at the feeling which made Sans pull back, revealing a big shit-eating grin.

"I guess I can handle 'the hot' pretty well if I may say so." He smirked.

You just felt embarrassed because you just could feel yourself being completely red. "Dude. You could have told me earlier you had a tongue."

"Magic can do a lot sweetheart." He said and grabbed your hand. "C'mon I'll treat you breakfast."

[ Grillbys, Underground | 10:04 AM ]

"We're having Grillbys again?" You asked when you were teleported in front of the familiar bar.

"Hey they have the best breakfast here, don't blame me." He said while forming his hands in an apologizing way.

The two of you entered Grillbys. Some people said hi to you and Sans, being the regular customers here.

You sat down and waited for Sans to sit down on his regular bar stool as well. When he sat down, a loud fart noise could be heard. You and Grillby snorted and high-fived each other.

"Watch where you sit down, some weirdos put woopie cushions on the seats." You laughed at Sans, who was hiding his shame in his jacket.

"Wait, did you two plan this!?" He nervously laughed.

"Now what if we did Sans." Grillby spoke.

"We did."

"And succeeded." He laughed. "Anyway, can I both get you something?"

"The regular for me, and (F/Breakfast) for the lady." Sans ordered.

"Nahw you know me so well Sansy."

"Better than you know. By the way.. Sansy?" He questioned you with a smug face.

Grillby placed a (F/Breakfast) in front of you. You smiled and ate it really quickly. "So I was wondering.."

"Oh god she is wondering again." Sans said in a sarcastic tone.

"No but seriously, you mentioned something about the seventh soul right? What were they like?" You said, making yourself comfortable on the old barstool.

Sans' eye sockets went black. You'd triggered him, good job (Y/N). "In some timelines they are a sweet and innocent child. They make friends with Pap, and heck, they even free us.
But in other timelines, they get possessed by the first soul, Chara. I'm not even sure how, but they kill all the monsters in the underground. No matter what, the underground goes empty either way."

No matter what, the underground goes empty either way. That's actually deep, damn. "But you are supposed to be either on the surface or dead right? How come you're here?"

"Because they reset."

[ Sans' Lab, Underground | 11:53 AM ]

Turns out, he has a lab in his house.

Sans and you were working on the new killer Mettaton. Sans was helping you, under the condition that you wouldn't say he helped you (mainly because he didn't want the attention). The two of you hadn't decided on a name, so you just chose to refer the project to as Mettaton NEO.

You were lost in thought while designing him though, you were just thinking about the possibilities you could survive. And unfortunately, the chances were rather small. You'd gotten an idea though.

"Hey Sans?"

"Hmm?"

"Do you have a book about souls?"

"This sounds like a really bad pickup line."

"It isn't. Answer the question boneboy."

"I don't. I think Alphys might have one though."

"Okay then I'm off to Alphys. We're almost done anyway. We can do the defences later." You said and gave him a quick kiss on his cheekbones before running to Hotland.

[ Lab, Underground | 12:03 PM ]

You knocked on the big metal door in front of you. A few seconds later, the yellow lizard living there, opened. A faint anime opening could be heard. You snickered a bit.

"O-Oh hey (Y/N)!" She said excited.

"Hey Al. Uh, Sans mentioned something about a book about souls. Can I borrow it?"

"Of course. W-wait here, I'll get it for you." Alphys said and ran inside.

You walked a bit into the doorway more, to see your (F/Anime) playing, and smiled at the thought of you and your sister watching it together.

You were caught off guard when Alphys handed the book to you.

"Thanks. Oh and by the way, Mettaton NEO is almost done."

"O-Oh nice. I like the n-name by the way."

"I'll be going then. See you." You waved her goodbye.

[ Bonezone, Underground | 12:24 PM ]

As soon you got home, you opened the book and began searching like mad. You read some pretty interesting things about souls, as well as determination and such. But what really was interesting was this.

'When one soul is split in half, under the consequences that the other half belongs to another being, it will regenerate in the substitute at the cost of the substitutes soul. 
Test 053 has shown us  that it approximately takes one to two years to form another, separate being.'

"Holy fuck." You basically shouted in happiness. You began laughing like mad.

There was hope.

"What's the ruckus 'bout?" Sans teleported in front of you. He looked at you with a confused expression. He probably doesn't know what's going on. You did neither.

"I've got a plan."
