Quantumtale After Life

"friskkkk...don't leaveeeee..." Sans said as he was clutching onto her foot like dear life. She looked down. 

"It's your and Gaster's fault i have to act all mature and shit and actually go to Papyrus parents meeting! What the hell were you three thinking when you made a giant volcano explosion....AND IT WASN'T EVEN WITH BAKING SODA!" Sans sniffled. 

"i'm sorrrrryyyy...let gaster handle itttt...." He said on the floor. Frisk shook her foot, her heels making a noise on the floor as she was walking around, closer to the mirror so she can do her make-up. 

"You're joking right?? HE is one of the culprits! Oh my god..." Frisk sighed, pinching the bridge of her nose. She then took off her bath-robe and Sans froze. She was wearing a buttoned up shirt and a tight black skirt. She really will do great as an ambassador someday. Her hair was curled and she was wearing the perfect amount of make-up. She took a small hand-bag Gaster bought her and was going to take her coat from her wardrobe. Sans had to shake himself out of the haze he was in. Frisk surely was like a mother to them sometimes...Guess this is what a feminine touch does, huh? 

"PAPYRUS! GET DRESSED, WE'LL BE LEAVING!!" Frisk called. Sans teleported to her foot again, stopping her and almost making her trip as he caught it. 

"SANS!" She said, frowning. He pouted. She shook her foot and started leaving. He teleported to the living room, where Papyrus was getting dressed. Gaster was sitting on the couch, pouting. He must have gotten a hell of a nagging from Papyrus. 

"FRISK! YEY! YOU LOOK MATURE! UNLIKE...THESE TWO..." Frisk giggled. 

"Come on, Papyrus. We need to get there in time. Also I'm taking the keys." Frisk said. Gaster looked at her in disbelief. 

"HOLD THE HELL UP- YOU CAN'T DRIVE--" Frisk raised her hands. 

"Excuse you! But yes I can and secondly. The Ambassadors of Spain and Mexico are true sweethearts for giving me a special perm for this~" She said as she pulled out a card. She winked at them and opened the door for Papyrus. She looked at both of them and frowned. 

"You do anything as reckless as me and I will hit your skulls together. Watch it." Frisk then left. Gaster grinned. 

"Wanna do an experiment?" Sans narrowed his eyes. 

"i'm scared of what this 'experiment' is..." Gaster smirked. 

"You'll see~" 

"YOUUUU JUST SWITCHED OUR BODIES! OH MY FUCKING GOD!!" Sans said in Gaster's body as Gaster was rocking himself back and forth in a corner. 

"AND I HAVE TO MEET UP WITH KAT TODAY! SHE NEEDS HELP IN THE LAB!" Sans spurted. 

"YOU WHAT?! OLD MAN, WATCH IT! DON'T MESS WITH ME--" Gaster made some weird screeches and Sans knew both of them were fucked. 

"okk....i'll pretend i am sick or something so that i won't have to go!" Gaster nodded. 

"Okk...Ok...Ok...It's fine...everything it's fine..." Gaster inhaled and exhaled, then started screeching again. That's when the car pulled into the garage and they both knew they were screwed. Frisk let Papyrus enter first and both Gaster and Sans froze as they saw Frisk entered with groceries as well. She looked at both of them and raised a brow. 

"Just because i act like a reckless bitch doesn't mean i can't be responsible, you know?" Frisk said. Papyrus was jumping around excitedly. 

"FATHER! YOU WON'T BELIEVE HOW WELL SHE HANDLED THE WHOLE SITUATION!!" Papyrus said. Sans smiled tensely as he patted Papyrus skull. 

"oh, really??" Papyrus nodded. Frisk eyed the two of them as she entered the kitchen and narrowed her eyes a bit. Shit- He forgot Frisk is way smarter than the average person. She must have figured something was wrong. 

"i-i see..." Frisk came back from the kitchen and leaned in the door-way. 

"Are you ok, Gaster? You seem...off...Also, Sans you're very quiet." Gaster chuckled. 

"O-Oh...I'm quiet? Sorry...me and dad aren't umm...feeling so well." Frisk narrowed her eyes. 

"Uhu...Did you eat something while we were gone??" Sans shrugged. 

"that must be it...haha..." For a second he saw a weird glim in Frisk's eyes and he felt weird. Like a chill running down his spine. Pidge shrugged. 

"If you say so." She went to her room. Sans and Gaster looked at each other. Papyrus smiled. 

"I'M GOING UPSTAIRS!" He rushed to his room and closed the door. Both skeletons relaxed and sighed. 

"This will be harder than we thought...Frisk is smart...She will surely figure it out. Also, may you explain to me why you're always so 'attracted' to her? Your body is pulling like a magnet towards her." Gaster said narrowing his sockets. 

"hah. no shit. never noticed." Sans responded, rolling his eye-lights. That's when Gaster's phone started ringing.

"shiii-" Sans said, hissing through his teeth. Gaster face-palmed. 

"ANSWER HER IDIOT!" Sans mocked his father and picked up the phone. 

"he- i mean...hello!" Sans said, stopping himself. 

"My God! Wings- I got your message! Are you ok?!" Sans chuckled. 

"y-yeah! pfft- totally...just a tiny stomach problem..heheh...." Half of Sans was feeling butterflies. It made his other half sick. Gaster gagged. 

"I can feel Frisk's feelings through the bond- BLEAGH!" Sans narrowed his sockets. 

"watch it old bastard--" Kat called Gaster's name through the phone. Sans coughed. 

"sorry about that- just sans and his antics. you know how he gets. we both umm- are a bit unwell." Sans said, trying to sound as much as he could like his father. Kat hummed. 

"It's decided! I'm coming over!" Sans spurted. 

"w-what? oh no- there's no need to--" But she already hanged up. Sans arm dropped. 

"we're fucked...." Sans said. Gaster groaned. 

Neither of the skeletons realized that Frisk had already figured it out. Sans (in Gaster's body) seemed to eye her weirdly. He must have realized she wasn't being as touchy. Kat was on the couch, drinking tea with Sans as Gaster was on an arm-chair and Frisk was on the other. Sans raised a brow. 

"did you two have a fight or something? you're usually sitting in his lap." Gaster eyed Sans dangerously. Frisk snorted. 

"Nah. It's nothing, don't worry about it." She crossed her legs and sipped her tea. Sans narrowed his sockets. He knew how to read Frisk well even if in Gaster's body. That was the first confirmation of her hypostasis. Next was when Kat asked for her favorite tea and Gaster (in Sans's body) kept telling him with his eyes how to make it. Frisk smirked as she realized what was happening. It was amusing to say the least. After all...These two were now experiencing matters of the soul only the other felt. Gaster was clearly grossed out about feeling her feelings. She could feel it through the bond. Which was the third thing that confirmed her idea. These two were lucky she was nice and was enjoying this or else she would have bashed their skulls into the wall. She sighed, set down her cup and stretched. 

"Welp...I'm going to punch the bag. See ya." Sans sockets widened a bit. He must have got the message. She was annoyed. 

"uh...kat...may i talk to my son?" The woman smiled sweetly and Sans pulled Gaster to the side. 

"the fuck did you shit-head do?!" Sans said. Gaster frowned. 

"She has been avoiding me the whole time- don't ask me!" Sans pinched the bridge above his nasal cavity. 

"go and make things right you old man! you won't destroy my relationship with frisk while i'm sweating my ass off to satisfy your girl! got it??" Gaster sighed and nodded, teleporting away. Next was making dumb jokes and talking about physics but more formally and with someone you didn't really love. Man he hated this. 

"Heyyyy Frisk." Gaster said, trying to sound laid back. Frisk snorted. 

"You sound like you're stressed with only 3 hours of sleep. What's up?" She asked as she stopped the bag. She knew he really was running on 3 hours of sleep. THAT wasn't Sans. That was Gaster. And the bond knew as well. Gaster blinked in surprise and chuckled warily. 

"But i slept the whole time with you...baby-bones?" Gaster said, a bit unsure of his words. Yup. That was Gaster. Frisk had to give him the fact he remembered the nickname Sans gave her. 

"My bad, lovely-bones. Now then, you ok?" She asked. Gaster shrugged. 

"Are YOU ok? are you mad at sa- i mean me?" Frisk snorted again. Man...They either think she's really stupid....or that they are better at this then they look. Frisk shook her head. 

"Why would I be?" She turned to the bag and widened her stance. Gaster looked at her. He must have never seen she actually had muscles almost like Undyne's. But she was like a daughter to him. For him, she was a fragile tiny flower. She wasn't the kid that survived years on her own and freed the whole Underground and Orphanage, she was a baby. And she won't blame him for seeing her like that. And she didn't mind, since no one ever saw her like that. It was nice to be pampered from time to time. She barely grew up with two toys and now she had dresses and make-up. It was nice...

 "Dunno." Gaster said with a shrug. Bonus points for that. Would have fooled her if she wasn't so analytical. Blame it on the years of primitive survival she had to do, but she was reading way too deep into people's actions at this point. And Sans knew that better than anyone. But guess the fact he switched bodies and half of him was focused on Kat didn't help. Pfft- Poor them. How amusing. 

"How humerus~" She said as she punched the bag a few times. It swinged and it hit Gaster. Strike 4...Sans would have dodged that. Sans was great at dodging. 

"Ouch...Welp- I'm gonna see what dad and Kat are doing...Maybe check on Papy- Paps..." Frisk smiled and nodded. 

"Sure thing. I'll be here. Apollo!!" Frisk said as red magic circled her hand and the bone monster rose from red flames, hitting the bag with a rosy-red outlined energy beam. Gaster looked with wide eyes. Frisk's eyes swirled with red as she, with one quick motion of her hand, stopped the fire. She looked at Gaster with her red eyes. She was sweating but she was in a tank top. Gaster only now saw the potential of his flower's beauty. She could truly become a great model if she ever tried. No wonder Sans was attracted to her. He had good taste but Frisk picking Sans?? She was truly raising the expectations high for his son. 

"Uhh- See ya!" And Gaster teleported away. He teleported in the kitchen the same time as Sans. 

"so? what?? i'm really getting bored here...at least paps is keeping her somewhat busy. she's blaming the fact i feel off thanks to the the fact you're ill." Gaster frowned. 

"It's so weird...she said she isn't mad and also your soul is going wild around her like a metal detector!" Sans scoffed. 

"i can assure you, yours does the same. but- you left her alone after she said she isn't mad?! what are you? and idiot in girls?!" Gaster blinked in surprise. 

"Uh-...what now?" Gaster asked. Sans face-palmed. 

"she'll probably wipe the floor clean with me after this- you dumbass old man! aren't ya supposed to be a scientist for heaven's sake?! god- she's PISSED!" Sans said, reading too much into Frisk and Gaster's actions. 

"Uhh...i don't get it??" Gaster said. Sans groaned. 

"just go and see what paps is doing...god damn it..."

They were all at the table and Sans was dreading this moment. He hope Gaster could act like him but...he couldn't. No puns no NOTHING! Not even ketchup. Frisk however didn't say anything. She just sometimes would snicker unnoticed or would smile and hold in a laugh. She somehow found this amusing? 

"BROTHER ARE YOU SURE YOU ARE ALRIGHT??" Papyrus asked Gaster. Frisk chuckled. 

"Don't worry, Papyrus. He is perfectly fine, i assure you. He's just 'confused'." She said, as she took a bite of the spaghetti she cooked. Kat raised a brow. 

"Oh? How is that??" Frisk shrugged. 

"Just like a small 'switch' going 'off'." Damn it- he was stuck in Gaster's body. His father has always been slow at messages like these. What did she mean?

"HMM...A PECULIAR WAY TO PUT IT IF YOU ASK ME?" Frisk giggled. 

"It's fine. And, the twins are at their grandmother you say?" Frisk asked, drifting away from the conversation. Sans frowned again and so did Gaster. Frisk was acting strange and this proved it and it was bother two halves of two different people. Two halves that together would have made Sans. Yes, Sans was bothered. 

Sans and Gaster were both fidgeting. Soon they will switch back. Frisk was just playing solitaire and has been for the past 15 minutes. Kat was talking with Papyrus. Any second now...Just switch back. And it happened. A blackness coming over the two as they passed out. Suddenly Sans blinked and saw himself close to Frisk. 

"YES!" Both skeletons said, jumping up. Frisk snorted. 

"Welcome back you two." She said as she put down a black ace. Sans and Gaster looked at her. 

"YOU KNEW?!" Frisk chuckled. 

"You sub estimate how well the bond and my analysis works." Sans scoffed. 

"of course she would have figured...you did and AWFUL job trying to be me. come here, baby-bones." Frisk giggled and sat down on his lap. 

"He did." Frisk said as she threw another card on the coffee table. 

"I DON'T UNDERSTAND WHAT'S HAPPENING..." Papyrus said. Kat frowned. 

"Did you two switch bodies?!" Gaster and Sans looked away. Kat sighed. 

"You are so dumb sometimes, Wings." Frisk laughed. 

"They both are, thank you." Kat looked at Frisk and nodded. 

"Of course, my dear. My, aren't you sharp. We should really talk more. How about i take you out sometime?" Frisk gasped. 

"Really? Oh my god!" Kat laughed at Frisk's excited reaction as she jumped up from Sans lap, leaving Sans and Gaster with blank sockets. 

"Yes, really! And you would look gorgeous with a strip of your hair another color! It works so well with the messy bob you have going on!" Frisk gasped, her eyes twinkling. 

"Oh my goddd! I can't wait to also call you my legal guardian!" Kat giggled. 

"Come, let me do your nails! We can watch a movie while these two think about what they've done!" Kat said as the two started walking to Frisk's room. 

"MAY I COME??" Frisk giggled. 

"Sure but this will be like a girl slumber party so you can leave if you want." Frisk and Kat started talking about girl things as Gaster and Sans were left alone, Papyrus following the girls. 

"Did they just..."

"ditch us..." 

"So they can hang together??" The two skeletons looked at each other and face-palmed. 

"We fucked up."
