Sans' POV

I was lazing on the couch, per usual, when Papyrus called me to breakfast.

"SANS! GET UP!"

"I'm not hungry, bro." I shifted, getting more comfortable so I could take a nap.

"GET UP SANS. WE ARE GOING TO HAVE A GUEST." He walked into the family room, looking down at me.

"Heh. Neat. Tell them hi from me." I shut my eyes, attempting to sleep. Unfortunately, Papyrus lifted me up off the couch, setting me on my feet.

"NO SANS. I WANT YOU TO SAY HI! THIS PERSON MEANS A LOT TO ME, AND IT WOULD BE NICE IF YOU LOOKED HALFWAY DECENT." He was about to send me up the stairs to change when them was a knock at the door. I moved to open it with magic, when it flew open anyway.

I saw one of the few monsters I didn't like in the entire Underground. Mettaton. He burst into the house, posing dramatically. "Mettaton has arrived!" He looked and spotted Papyrus, eye lighting up; the other was covered by his dumb robot hair. "Papy darling!~" He ran over and hugged Papyrus, causing him to blush. Oh boy..

"H-HI M-M-METTATON!"

"It's so good to see you again! So, it looks like we have the house to ourselves?~" he cooed, causing my metaphorical blood to boil.

"OH NO, METTATON! IT'S EVEN BETTER! MY BROTHER SANS IS HERE!" He lifted me up, and I just raised an eyebrow at him.

"Sup, MTT? Ready to spend the day with me and my bro?" I grinned as Mettaton's smile fell.

"AHA! I CAN ALREADY SEE YOU TWO WILL BE GREAT FRIENDS! NYEH HEH!"

I snapped, teleporting to the door of the kitchen. Mettaton jumped when I disappeared. "Let's have breakfast, shall we?" He spun around, startled that I was in the kitchen. Maybe today would be okay after all.

~-~-~

Mettaton ended up spending the whole day with us. It was actually okay, besides the fact that Mettaton kept trying to sneak off with Papyrus without me. I didn't trust that robot with my brother alone yet.

That evening, we decided to go on a walk through Waterfall. Just as we were walking out the door, Mettaton stopped. "Oh Papy, I need to use the restroom before we leave. Sans, will you show me where it is?" Suspicious, I stepped back inside the house. Why would a robot need a bathroom? He slammed the door behind us.

"Why won't you leave us alone?" He put his hands on his hips.

"Because I don't trust you with my baby brother." I sassed right back.

"Why not?"

"You're flirtatious to everyone! I won't have you breaking my little Papy's heart."

He sighed, face relaxing. "Look, I can see why you think that. But please believe me when I say Papyrus is different. Most of the flirting is for the media; but I truly love Papyrus. Please Sans."

I stared into his face, seeing the open expression. I nodded slightly. "Okay. But if you do anything to him, you're gonna have a bad time, capiche?"

We stepped back outside, Papyrus jumping up. He had been building a mini-snow-Papyrus in the snow. "ARE WE READY TO GO?"

"Yep. Let's go before Mettaton gets cold feet again, heh."

Papyrus growled with a smile on his face before running off, pulling Mettaton with him, prattling on about his favorite echo flower.

It was hard to let go of my little Papy, but I knew he really looked up to Mettaton, and I could trust him. I sighed, smiling, and took a shortcut to Waterfall; hopefully I could get in a nap before they got there.

I just wrote a Papyton, but it's not in Papyrus' OR Mettaton's POV.
Huh.

Love you, my little stars!
