Chapter 1

Mettaton was not pleased to put it simply. After an... Accident involving Undyne, Papyrus and Alphys' kitchen he was out of a home (he lived with Alphys). Undyne had allowed Alphys to move in with her temporarily but she didn't have enough room for two guests... Heck she didn't even have a guest room. So Mettaton moved in with Undyne's partner in crime, Papyrus and along with him, Sans. Even since Alphys and Undyne had been dating they had hung around the skeleton brothers more, while Mettaton got along rather well with Papyrus, Sans however, was another matter. They just didn't see eye to eye. Perhaps Mettaton's flirtatious nature had put him off, or that Mettaton would spend a majority of his time off with Papyrus when they were around, who knows. Sans wasn't openly aggressive, he always had his chill, laid back demeanour and had the nerve to ignore him when they were alone.

Mettaton was now walking on his way to the skeleton brothers' house. Like the skeleton's previous house, it was in a colder part of town than where Alphys lived. He looked around for their house and saw a large waving figure it was Papyrus and as usual, Sans right beside him.
"METTATON!" He called out excitedly, well, more excited than usual. Sans sighed quietly, Mettaton walked over to the skeletons his usual confident mix between a smile and a smirk.
"Hello Papyrus darling~" he cooed then looked at Sans "hello Sansy~" he said just as enthusiastically though it was more to rile him up than be nice, it wasn't exactly out of malice but it was amusing. "Don't call me that" was Sans immediate response, still chill as ever.
"IT IS GOOD TO SEE YOU METTATON!" Papyrus exclaimed "I, THE GREAT PAPYRUS HAVE MADE 'WELCOME TO OUR HOUSE FRIENDSHIP SPAGETTI JUST FOR YOUR ARRIVAL!" Papyrus said proudly, puffing up his chest. Mettaton smiled more.
"That sounds delicious darling!" He said lacing his hands together in a happy-looking pose. Mettaton knew that Papyrus' cooking skills were... interesting. Thankfully, he could turn his taste sensors off at will.

Sans watched Papyrus lead Mettaton into their house and then soon followed after.
'This is going to be a pain...' Sans thought as he watched Papyrus energetically show Mettaton around their house. It was surprising, Sans had believed that Mettaton would have brought a ton of things along with him, mostly glittering things but that was not the case. All Mettaton had brought with him was a hairbrush, a battery charging cord, a couple pairs of clothes and an mp3 player full of his cousin's music. Sans of course didn't mind, this way, he wouldn't have to carry his luggage. Sans looked around for the two Papyrus was now dishing up his 'welcome to our house friendship spaghetti.' Mettaton was right by him, too close for Sans' liking, he was leaning on Papyrus a bit as Papyrus put some spaghetti on three plates.
'Can he even eat?' Sans thought to himself before walking in, sneaking up behind Papyrus and poking the sides of his spine, making him jump and Mettaton get off him. Papyrus turned around to face Sans.
"SANS I TOLD YOU TO STOP DOING THAT!" He exclaimed and Sans chuckled.
"Why?" he asked
"BECAUSE IT'S NOT FUNNY!"
"Well I found it pretty rib ticklin'"
"OH MY GOD SANS"

Mettaton and Papyrus time successfully interrupted.

Mettaton was sitting at the table in a listening pose as Papyrus rambled on and on about several different topics, mostly spaghetti, Sans was silent the whole time. After a while he had had enough, his brother was awesome, heck yes, but he needed something else to do.
"Whelp Pap, I'm full" Sans said grinning lazily as usual "I'm gonna go to bed" he said
"BUT SANS, WE MUST ADDRESS A VERY SERIOUS ISSUE!" Papyrus protested. Sans looked at him with a raised brow (excuse the human terms) "WE DO NOT HAVE A GUEST ROOM. METTATON NEEDS TO SLEEP SOMEWHERE. I, THE GREAT PAPYRUS, AM WILLING TO GIVE UP MY AMAZINGLY COOL BED, BUT I WANTED TO CHECK WITH YOU." Papyrus explained. Mettaton stood beside Papyrus,
"I'm fine with sharing" he stated and put a hand on Papyrus's bony shoulder, squeezing it lightly. Sans was instantly suspicious again, not liking the flirtatious gesture it made a sinking feeling in his stomach well, if he had a stomach, but a sinking feeling all the same. He trusted Mettaton the same amount a mouse trusted a snake. So not at all, especially not in the same bed as his brother.
"Why doesn't Mettaton stay on the couch" Sans replied. Mettaton looked partially shocked and appalled but remembered his 'manners' as their house guest.
"Of course, I am a guest after all. I guess it's normal to have the poor, homeless, extremely beautiful guest sleep on the couch." he guilt tripped dramatically. This instantly got to Papyrus but Sans just rolled his eyes.

"THAT DOESN'T AOUND LIKE SOMETHING A GOOD A HOST WOULD DO METTATON YOU CAN SLEEP IN MY BED I WILL TAKE THE COUCH! THE GREAT PAPYRUS IS A GREAT HOST!" Papyrus exclaimed. Mettaton smiled at him, batting his eyelashes "You're too kind" he said happily, then glancing at Sans. Sans didn't really want his brother sleeping on the couch, it would be uncomfortable for Papyrus but there's no way in hell his brother or Mettaton would want his bed, way too messy. He sunk a bit more in his hoodie a bit and sighed quietly.
"Hey Pap remember that airbed we got?" Sans said grabbing both his brother and the robots' attention again. "Wanna use that? It'd be more comfortable than the couch..." he said.
"OH YES WE USED THAT WHEN FRISK CAME OVER TO MAKE A FORT" Papyrus said grinning at the memory. "I SHALL PREPARE IT IN MY ROOM AND METTATON CAN USE MY BED!" He stated and rushed upstairs, Mettaton cheerfully prancing behind, giving a glace back at Sans before going up. Sans sighed and plonked onto the couch after walking to the lounge room might as well stay up encase Papyrus needs help, or tries to blow it up with his mouth again. He turned the TV on, thankfully on the surface they had a variety of shows so he didn't have to watch a pre-recorded episode of Mettaton's show, that would be too much Mettaton to handle.

After about twenty minutes Papyrus rushed down the stairs again, with a quietly chuckling Mettaton in tow.
"BROTHER I FINALLY BLEW UP THE BED!" Papyrus exclaimed proudly. Sans grinned as usual.
"That's good bro" he replied inwardly wondering why it took so long…

Sorry if it's not good this is the first fic I've written in a very long time ;A;
