Alright, so this was requested from a friend of mine and they wanted a few short stories. So… I guess you guys can request some short stories and oneshots. This is the first one. XD.

Basically there are no thunderstorms in the Underground. But on the surface… Yeah and Sans and Papyrus don't take it too well.

Request some more stories and I'll do my best!

"Take care of Frisk, alright?" Toriel said as she straightened Asriel's hair. "Make sure they're in bed before eight."

"Right." Sans muttered, his skull hitting the back of the sofa. "Uh-huh…"

"Don't give them any soda before bed. And no chocolate, either."

"Uh-huh…" Sans muttered, glancing at Asriel, who was dressed in a very smart tuxedo. Sans sniggered and waved Asriel over. "Hey, kiddo, I got you something."

"What is it, Sans?" Asriel asked, looking thoroughly disgruntled.

"I got ya a banana." Sans sniggered. "For your monkey suit."

Asriel's cheeks were coloured a bright red under his fur and Toriel giggled. Papyrus, who was busy in the kitchen, poked his head out the doorway, his eyes burning with rage. "SANS… STOP."

Sans sniggered and Asriel stomped off to his mother, who proceeded to run a comb through the top of his head. "Sans, are you sure that Frisk and Papyrus won't like to come along? I'm sure you'd enjoy it."

"Nah, Tori. It's cool." Sans waved a hand and then gave her a wink. "I'll watch 'em. No need to worry. Besides, Papyrus and I aren't really a fan of these royal guard things."

"Neither am I." Asriel muttered, but Toriel yanked a knot out of his fur and he winced. She gave him a withering look before picking up her purse. "Your father will be around shortly." She muttered a little sourly. "Now, let's say goodbye to Frisk."

Frisk, as if on cue, appeared at the top of the stairs, smiling and dressed in their skeleton pyjamas. They rushed downstairs and jumped into Toriel's arms, hugging her tightly. Toriel laughed and kissed the top of Frisk's head. "We'll be back after midnight, dear. Luckily for you the ambassador doesn't have to come along, or you'd be just as bored as your brother."

"Can't I stay with Frisk?" Asriel moaned, tugging at the collar of his shirt. "It's gonna suck."

"Language." Toriel warned him. "And you must come, Asriel. It'll help you when you become an official one day."

Asriel stalked to the door and Toriel giggled. "Have fun, you three! And say hello to Gaster for me when he comes back!"

"Sure thing, Tori!" Sans said, smiling. Frisk clambered over the couch and landed solidly on Sans' ribcage. He huffed out a grunt and sniggered, patting Frisk's head. "Sup, twerp? You hungry?"

Frisk nodded.

"Welp… Gaster's gonna be here in a minute, then we can eat."

"SANS, WHAT'S A THUNDERSTORM?"

Sans glanced toward the kitchen, frowning. "A… what?"

"THUNDERSTORM!" Papyrus repeated, striding out of the kitchen in his apron. "WHAT IS IT?"

Sans scratched his skull. "Uh… It's a… uh…" He glanced at Frisk, who was blinking in surprise. Then a massive grin crossed their face.

There aren't any storms in the Underground?

"Uh… snow storms, yeah, but that's mainly from the winds that pass through the caverns." Sans shrugged. "I read about 'em, but uh… yeah… never really had one."

Frisk shrugged. They're something. The whole sky lights up.

"REALLY?!" Papyrus asked, leaning on the couch. "WOWIE! SANS! WE MUST BE OUTSIDE WHEN THIS HAPPENS!"

Frisk immediately shook their head. We'll get wet.

Sans shrugged again. "Well… let's watch some mindless television while we wait for Gaster."

Mettaton had acquired several shows whilst on the surface. There was now Cooking With a Killer Robot; The Forbidden Love of A Human and A Monster, the sequel. It was enough to pass the time with. A few hours later, it began to rain. Sans glanced outside as the door opened and Gaster stepped inside, shaking himself like a wet dog.

Stars. It's pouring out there. He shook his head and dumped his briefcase off to the side as Frisk jumped up to meet him. Hello, child. He signed happily, picking Frisk up and ruffling their hair. I'm quite excited; I hear thunderstorms are spectacular. Superheated air crashing and meshing to create a reaction so strong that it just-

"Hey, pops. Mind explaining what a thunderstorm is?" Sans said, looking more confused than ever.

Ah, yes. Well, Sans, a thunderstorm is a… well, a storm. It's a state of the earth's atmosphere, a disturbed state in which clouds gather and the air is charged. This causes lightning. It's quite spectacular, Sans. You'd be fascinated. There's even some fog outside.

Sans cracked a smile. "So… When the fog burns off it won't be mist."

"SANS! OH MY GOD!" Papyrus slumped over the couch and picked Sans up, shaking him by the shoulders. "NO MORE PUNS!"

"Sorry, bro." Sans sniggered. "I just hear that lightning storms can be very striking."

Papyrus left the room, dumping Sans on the coffee table. Sans snorted with laughter and Gaster shook his head. Oh, Sans. He sighed, patting Frisk on the head and placing them on the sofa as he passed. I'll help Papyrus with dinner; you two must behave.

"Don't worry, G." Sans said as Frisk giggled. "We won't take you by storm. We'll just blow away all of your expectations."

"SANS!"

The storm came shortly after, as the three of them were sitting at the table and eating spaghetti. Sans was sleeping, skull thrown back and his snores echoing in the relatively empty house.

So, child, how have you been?

Frisk began to answer when all of a sudden, the power went out. Papyrus let out a high-pitched scream and Sans jerked awake at the noise.

"Whoa!" He exclaimed. "Who turned out the lights?"

That must be the storm. Gaster signed, his glowing blue hands illuminating his skull. I shall retrieve some candles.

"GAH! DON'T LEAVE US! IT'S SO DARK!" Papyrus whimpered, groping around in the dark. "SANS! WHERE ARE YOU?!"

"I'm right here, bro."

"OH MY GOD, SOMETHING TOUCHED MY FOOT!"

"Bro. You just stepped on my face."

"OH."

Calm down, Papyrus. It's perfectly normal for the power to go out. Frisk? Where are you?

Frisk was giggling and followed Gaster to one of the cupboards, where he began to light candles and place them around the house.

Now… where have Sans and Papyrus gone off to? He glanced out the window, where there was a small flash of lightning and a clap of thunder. There was some screaming in the house and Gaster winced, picking up Frisk. Well… it begins.

"GASSSSSTTTTEEERRRRRRR!" Came the distressed cry.

Gaster's face twisted into a form of utter confusion. Uh… there's Papyrus…

"GASSSSSTTTTEEERRRRRRR!" Papyrus came screaming around the corner of the passageway and Gaster was bowled over, sending Frisk flying. "OH MY GOD WE'RE GOING TO DIE! THE SKY'S TAKING PICTURES OF US!"

Papyrus… please. Get off my ribs.

"BUT GASTER!" Papyrus whimpered as Frisk giggled wildly on the floor. Gaster eventually got to his feet, Papyrus still clinging to Gaster like a frightened child. "THERE'S BRIGHT FLASHES OF LIGHT IN THE SKY! WE NEED TO HIDE!"

No, Papyrus, we do not need to hide. Gaster heaved a sigh and patted Papyrus on the back. Now, where's Sans?

There was a loud crash from outside and the sound of a gaster blaster getting ready for a blast. There was a bright flash of blue outside and Gaster's eye sockets went wide. He glanced back over at Frisk, who had frozen in their spot before slowly turning to face Papyrus. Is your brother outside?

"HE IS PROTECTING THE HOUSE FROM THE BRIGHT FLASHES!" Papyrus moaned, curled tightly around Gaster. "GASTER, DO NOT FEAR! THE G-GREAT PAPYRUS SHALL-" There was a bright flash of lightning and a loud clap of thunder. "OH GOD KILL IT SANS!"

There was another blast from outside and the window suddenly shattered. Gaster winced and Frisk stood behind him, clutching his leg.

"Guys it's still there!" Sans yelled, picking himself up from the ground and shaking off broken glass. Gaster blinked several times. Sans… did you just… jump through the… window?

"No…" Sans mumbled, shaking some glass out of his jacket.

Gaster tapped his foot, one hand on his hip. Uh-huh. And… that wasn't a blast from one of your toys, was it?

Frisk giggled and signed in the dark, their hands barely visible. It's just thunder.

As if on cue, there was another flash of lightning and the thunder rattled the windows. When the light faded, Sans was nowhere to be seen. Frisk blinked and looked around as Papyrus clutched Gaster.

"IT TOOK SANS!"

No. Gaster said, bending down and peering under the sofa. There he is.

Frisk went down on their hands and knees and saw Sans' glowing blue eye, illuminating his terrified face as he hid under the furniture. His bones were rattling and he glanced around frantically.

Sans… come out from under the furniture. Gaster said, holding out his hand. Frisk held out their hand as well, smiling.

"Uh… I…" Sans stuttered, his bones rattling loudly in fear as Papyrus clutched Gaster. "C-can't. I'm… uh… s-stuck."

Frisk blinked before they began to giggle. The giggle then devolved into laughter and soon they were doubled over, the rain hammering on the rooftop. Sans glowered at Frisk, but another flash of lightning caused him to jump and he drew the strings of his hoodie, hiding his face.

"SANS!" Papyrus called, clambering onto Gaster's shoulders. Gaster huffed a sigh and waved his hand. A large, formidable blaster with massive teeth and glowing purple eyes appeared, shaking itself before it flipped the sofa over. The blaster picked Sans up by his jacket and Sans barely struggled, his bones rattling so loud that Frisk felt sorry for him.

Sans. The thunder is merely a sound. It cannot harm you.

Sans was still under his hoodie and couldn't see what Gaster had said, but Papyrus spoke up, sounding surprised. "IT CAN'T? BUT IT'S SO LOUD!"

Yes, son. It is loud, but it cannot harm us. And the lightning is actually quite beautiful, if you would let me show you.

"BEAUTIFUL?" Papyrus enquired as the blaster set Sans gently on the carpet. Frisk walked up to him and patted his head comfortingly as Gaster extricated Papyrus from his shoulders.

Yes. Now, why don't you get some tea? I'll go upstairs and prepare us a… well, a viewing balcony.

Sans only moved when Gaster and his blaster disappeared upstairs. His bones shook and Frisk hugged him tightly as Papyrus bent down to make sure his brother was alright.

"ARE YOU OK, BROTHER?"

Sans took a shaky breath. "Y-yeah." He said in a shaky voice. "S-sorry. Just… it reminds me of…" He shuddered and Papyrus flopped down to sit next to him.

"WHAT IS IT, BROTHER?"

Frisk glanced at Sans, seeing a blue tear creep to his eye socket. Frisk held him tightly and he sniffed. "Yeah… H—hey, Pap, why don't you get some tea…"

"RIGHT ON IT, BROTHER!" Papyrus said, leaping to his feet and diving toward the kitchen. "I SHALL MAKE THE BEST TEA EVER! DO NOT FEAR, BROTHER! THIS TEA SHALL BE AMAZING!"

Sans smiled a little in response. He glanced at Frisk, then sighed. "Sorry, kiddo. Just never been this scared since… well… since…"

You don't have to tell me. Frisk said, signing and smiling in a comforting manner. I know… it reminds you of our fight, doesn't it?

Sans heaved a sigh and drew the strings of his hoodie again, hiding his face. "Yeah… I guess. It just sounds like… When I-"

Wanna help Papyrus with the tea? Frisk asked, getting to their feet. He might burn down the kitchen.

Sans smiled. "Yeah… I wouldn't want to tea that."

"SANS!"

After making a large pot of tea, Sans, Papyrus and Frisk mounted the stairs. Sans wasn't shaking as much, but his eye sockets were completely black and he still shuddered when the lightning and thunder struck. Papyrus, however, seemed happier to know that it couldn't hurt him or his brother, and practically ran up the steps with the tea pot.

"COME ON, FRISK! SANS! HURRY UP!"

They eventually reached Gaster's room, which was strewn with blueprints, papers and other forms of stationery. Gaster, however, was nowhere to be seen.

"GASTER?" Papyrus called, glancing around.

Over here, Papyrus. His glowing blue hands signed near the end of the room. Gaster appeared, smiling widely. Now, shall we begin? Everyone come stand here and lock hands.

Sans hesitated, but Frisk tugged on his jacket and he finally complied, grumbling to himself. Gaster held hands with Frisk and papyrus, Frisk holding Sans' hand tightly. Gaster's hands began to glow a bright purple and there was the gut-wrenching feeling of teleportation.

Eventually, after a few seconds, they were all sitting in what appeared to be a oddly-shaped room. After a few seconds, Frisk let out a squeal of surprise.

Ah, it appears Frisk has got it. Gaster said, smiling.

They were inside the maw of a large gaster blaster, which was at least three times the size of a normal blaster. Sans' eye sockets went wide and he glanced around.

"Uh… is this safe?"

Gaster shrugged.

There was a bright flash of lightning, but no thunder. Frisk jumped to their feet and ran to what was the blaster's eye socket, staring out into the rain. Sans, you have to see this! They signed frantically, bouncing on their feet.

"WOWIE! LET ME SEE, HUMAN!" Papyrus rushed to Frisk's side, bouncing on the heels of his feet and staring outside. There was another strike of lightning and Papyrus squealed in happiness.

"OH MY GOD! SANS! YOU HAVE TO SEE THIS! IT'S SO BEAUTIFUL!"

"Y-yeah." Sans chattered, his bones rattling even harder. Frisk glanced back at him as Gaster, who was sitting calmly by the teeth, cracked open one eye.

Sans… it cannot harm you. Gaster signed, glancing toward Frisk and Papyrus. Would you… like me to show you?

"I'm q-quite g-good, G." Sans stuttered, pulling on the strings of hoodie. "Uh… how high up are we?"

Not too high. Maybe a hundred feet.

"T-that all?"

Above the clouds.

"Oh god."

"SANS! COME LOOK AT THIS! THE CLOUDS ARE SO PRETTY!"

"I think I'm gonna be sick, bro." Sans wheezed. Gaster stood and calmly strode to Sans, holding out his hand. Sans glanced up into Gaster's eye sockets before sighing and taking his hand. Gaster led him calmly to the eye socket, whilst he stood trembling.

They were high above the clouds and below them was spectacular lightshow. Gaster smiled pleasantly and Frisk bounced excitedly on their feet. Sans had to admit… it was pretty.

"It's… uh… pretty shocking." Sans said nervously.

"SANS!" Papyrus snapped before picking Sans up so he could get a better view. "LOOK! IT'S LIKE A MOVIE! BUT… WITH DANGEORUS LIGHTS."

Gaster chuckled and Frisk glanced up at Sans before reaching up and clasping his hand. Sans squeezed back, smiling nervously. The lighting reminded him of killing Frisk, over and over again in the Judgement Hall, but if they were smiling… then they weren't thinking about it. Sans squeezed their hand and watched the lightning, grinning widely.

"Hey, hey Papyrus." He sniggered as Papyrus hauled him a little higher. "Waddya call it when it rains chickens and ducks?"

"SANS. I AM NOT GOING TO REPLY TO THAT." Papyrus said, Gaster snickering behind him.

"Aw, c'mon, bro. Please?"

Papyrus heaved a large sigh. "FINE. WHAT DO YOU CALL IT?"

"You call it fowl weather."

"THAT WAS A TERRIBLE JOKE."

But he was smiling, and so was Frisk. Gaster eventually sent the blaster back to the house and they all went to bed. However, Sans stayed up a little later than normal, just to watch the lightning and cross off another day on his calendar. He'd originally bought it to see how long Frisk would last before they did another reset.

Now it was just used to cross off good and bad days.

So far... most of them were good.
