INVITATION TO THE GREAT PAPYRUS' BIRTHDAY PARTY

It's been 5 years since Frisk fell underground. After getting killed countless times by Omega Flowey, she came to wonder why she was trying to return to the surface so badly. With Asgore gone and Toriel taking care of the underground, how could she just leave all her new friends? Deciding it wasn't right to try to leave anymore, she left the throne room before Flowey had the chance to appear again. As she ran down Judgement Hall, Flowey appeared in the throne room. To his dismay, Frisk wasn't there. He was frazzled by her not being there that he let his mind wander a bit enough for the 6 human souls to escape from him. The souls vanished, and so did their bodies. Frisk ran all the way to MTT Resort where Sans was chilling, When she saw him, she abruptly stopped running. Her heavy breathing was heard by Sans as he too turned to look at her. At that time, Frisk was just a scared 10 year old girl and Sans was a 25 year old comedian skeleton. 5 years have passed since Sans and Papyrus took Frisk in to their home. Papyrus ended up falling in love with a new robot that Alphys built. It was a female version of Mettaton NEO named Mettaton EX. Mettaton NEO calls this new robot his sister proudly as she has charm, style, and grace. Papyrus and Mettaton EX got married last year and have lived in her mansion in the capital. Sans doesn't have to work as a royal guardsman anymore, but work has become harder to find. The only thing Frisk was qualified for, because of her lack of experience, was as a pole dancer. She had made a costume to make her look like a monster and applied for the job, behind Sans' back. He was already stressed enough about finding work and paying the bills, she didn't want to stress him any further. She didn't know the real reason why Sans didn't want her dancing for money. Yeah he would worry about her and her safety. But there was something else.

"Frisk! I finally found a job! The mailman passed away from old age, and his son is still too young to do any working, so I applied for the position!" exclaimed Sans as he crashed through the front door.

Frisk was in the kitchen making hamburgers and french fries with a side of spaghetti.

"Really? That's great news for us!" happily said Frisk.

On the inside though she was wracked with nerves. How would she explain the checks that would come to their address with a name Mary Mack on them? She couldn't lie to him or find a random monster and say that it's her and have that random monster get her hard earned money. She had to think. Of course! There was a mailbox in front of the door to the Ruins. All she had to do was find her files at her job and change the address so her money gets sent there instead of to Sans' house. That might make him a little confused, but as long as she doesn't collect her money with him around, it should be easy to pull off. Or...she could put on her disguise and go there to pick up the money just in case he should see her going there to pick up the checks.

Papyrus and Mettaton EX came over just then and knocked over Sans in the process.

"YOU GUYS ARE INVITED TO MY BIRTHDAY PARTY! I WILL BE TURNING 21! OH FRISK, I'M AFRAID YOU'RE STLL TOO YOUNG TO DRINK ALCOHOL..."said Papyrus.

Sans stood up.

"I'll bring some soda for the kid so she can come and celebrate with you," winked Sans.

"OOH THAT'S BRILLIANT! THANK YOU SANS!" thanked Papyrus.

Mettaton EX looked over at Frisk and smiled.

"The woman of the house is cooking eh? What did you make dearie?" asked Mettaton.

"Er, it's nothing fancy. Just burgers, fries, spaghetti-"

"DID YOU SAY SPAGHETTI?! HONEY, CAN WE EAT HERE FOR DINNER?" begged Papyrus.

Mettaton smiled warmly. "Of course, dear."

Sans, Papyrus, and Mettaton all sat down at the dinner table as they waited for Frisk to finish cooking the food.

"So, I heard you got a new job?" asked Mettaton.

"Yeah. I'm the new mailman. If this job doesn't work out, I guess I can always call back MTT Resort for the janitorial job. Could you make sure I get a job one way or another there in case this job doesn't work out?" asked Sans.

"But of course! I am the star after all," blinked Mettaton.

Frisk came out with the food.

"Thanks kid."

"THANK YOU HUMAN!"

"Thanks darling."

"You're all welcome. Papyrus, you don't have to invite me to your mature birthday party," glumly said Frisk.

She couldn't just come out and say she was working that night. Because if she did, she'd have to explain where and that wouldn't sit right with anyone. She had to come up with something and not sound too suspicious. Sans eyed Frisk. He was curious as to why she would not want to come to his brother's party. Mettaton looked at Frisk with a face that yelled "what's wrong". Papyrus just looked at Frisk in shock.

"W-W-WHY WOULDN'T YOU WANT TO COME TO MY BIRTHDAY PARTY? IT'S NOT JUST GOING TO BE ALCOHOL. THERE'S GOING TO BE CAKE, BOARD GAMES, PUZZLES, AND A BOUNCY HOUSE!"

Frisk couldn't help but feel immense guilt.

"I just feel like a kid who doesn't belong at a party for adults. Besides, this house is a constant mess. It's going to take a long time to clean it up."

"Frisk? What's REALLY wrong?" asked Sans.

Frisk's face turned red in embarrasment. Shoot! Sans was sharp as ever. He simply knew her too well. Maybe there was a way around that...

"Those are my reasons Sans. I'm a kid who has no business in adult affairs."

"Frisk, I drink all the time. I literally have beer in the fridge and you live with me. How is this going to be different?"

She had to make up a lie to completely catch him off guard. She has a crush on him and he knows it. She could use that!

"That's different because you're like a dad to me. I literally do not have anyone else to live with anyway."

Sans looked so shocked right now that it hurt Frisk to see him so affected by a lie.

In Sans' mind: she thinks of me as her dad?! I could've sworn she had a crush on me! Darn it! That means I can't come on to her when she's older. Why am I thinking that?

Sans cleared his throat. Papyrus was on the verge of tears now. He didn't want to celebrate his birthday if his best friend wouldn't be there. When he stopped eating the spaghetti and trembled, Mettaton stood up and helped Papyrus up.

"I think it's best we leave and continue preparing for his big party, hahaha."

"THE GREAT PAPYRUS DOESN'T WANT A PARTY ANYMORE!"

Mettaton rushed Papyrus out of the house and took the boat back home. Sans quickly turned on Frisk.

"What the hell Frisk? Papyrus isn't going to celebrate his party anymore because of your selfishness!"

Even though Sans got the job as a mailman, the bills are too high for him to pay off alone. This needed to be done.

"He'll get over it and be okay. He has Mettaton EX to help him get through things like this. I'll come to his parties when I'm an adult."

"No. You're going to his birthday party even if I have to drag you there myself. If the mess in the house really bothered you, you would've cleaned up long ago and you know that's true," said Sans.

"Whatever. I'm not even hungry anymore, Good night."

Frisk collected her plate as well as Papyrus' and Mettaton's plates and did the dishes. She then went to her room which used to be Papyrus' room. Instead of a race car bed it now has a unicorn bed. Instead of childrens books, there are now sci fi books and mystery books. Instead of a pirate flag, she has a unicorn poster. Instead of action figures, she has a desk with mystical creature figurines. She still has a computer in the room. Sans was downstairs racking his brain for Frisk's odd behavior at the dinner table.

"Could it be she feels misunderstood by us because she's a kid hanging out with adults? Does she miss having friends her age?" he pondered.

All of these things were possible answers for her adolescent behavior.

"I mean, it could be because of her hormones as well. She is a 15 year old girl after all..."

Only Mettaton NEO knew why she behaved the way she did. When his sister told him about it, he pretended to not know a thing. He runs the dance club that Frisk applied to and told him to help her keep her secret. He wanted something in return.

"Fine. I'll keep your secret. All you have to do for me in return, is give me 10 percent of every check, and kiss me after every shift," winked Mettaton NEO.

"K-k-kiss you?! I'm a 15 year old and you're, like, how old are you?"

"Past 30 but who cares? I'm keeping your secret so you'll have no choice but to keep mine."

Frisk shuddered at the thought of having to kiss Mettaton NEO after every shift. She'll be wearing a disguise so no one will know Frisk is there to begin with but the fact she'll know is enough to send shivers down her spine.

"I just have to save up 2000 gold, and our bills will be caught up. With experience, I'll be able to land a job at Grillby's since the requirement for a job is at least 1 year experience with any other job," thought Frisk. She had a plan and she was going to stick to it. Her first shift started that night. Luckily for her, Sans sleeps at 7pm since he has to wake up early for his new job. She tiptoed to her closet and threw on her monster disguise. She had her blanket cover her pillows to make it look like she was sleeping in her bed, and she climbed out her window.

"Wanna ride in my boat? Tra la la..."asked the river person.

"Yes. I need to go to Hotland."

"Then we're off."

The boat grew legs and it sprinted across the water to Hotland. Frisk got off the boat and ran to the dance club that was past Hotland and in the capital. It was a bit of a run, but she had no choice since the river didn't make it to the capital. Mettaton NEO saw disguised Frisk walk in. He smiled lustfully at her, making her shudder inside her getup.

"Miss Mary Mack! Welcome! I'll have you dance on that stage there. I want you to follow my instructions when I say do not leave any drinks unattended, and remember to have fun! When you have fun, the customers have fun."

"R-r-right, sir. Thank you for the advice. I'll get to work right away," said Frisk.

Frisk knew what she was doing when she made her costume. She made Mary Mack look like a fusion between Shyren and Temmie but with a super model body. Basically, the face looked like Temmie's but instead of droopy ears on the side of the head were the gills inspired by Shyren. She took some inspiration from Undyne as she made the hair red and long. Every customer flocked to her stage and threw tips left and right. They were small tips though. Which didn't make sense as she saw the other dancers getting twice the amount of what she was getting.

"These men either don't have much money to spend anymore, they think I'm a lousy dancer but a hot monster, or Mettaton made sure to have men on the side just for me to only give me a little bit of money," she thought.

It wasn't that they didn't have enough money, they were loaded. She wasn't lousy at dancing at all. In fact, some would say she's just as good as both Mettatons. It was indeed the third option. At the end of her shift, she had only made 200 gold whereas the other dancers made over 300. She looked at the clock. Her shift was over. It was time to give Mettaton 10 percent, give him a kiss, and go back home for the night.

"Mary Mack, I'm feeling generous. I'll only ask for 50 percent from now on. I know you have goals and you don't want to be here long, so I'll compromise," said Mettaton NEO.

"Thank you."

She turned to leave but

"I still want that kiss, dearie," Mettaton licked his lips.

"O-of course..." Frisk's cheeks reddened.

She walked up to him. He laughed at her naivety.

"What's so funny?" asked Frisk.

"I should have specified. Without wearing your costume. I want to taste your real lips," said Mettaton.

"B-but I'm practically naked underneath! It's not like just the head part is detachable. It's a onesie."

"Even better," rumbled Mettaton's voice in a low pitch.

Shakily she took off her costume, revealing her D cup breasts chilling in her black bra and black panties. This excited Mettaton NEO. He pulled her close right away and closed the gap between them, causing a sound from Frisk as she was not ready to be taken off guard. He slowly pulled away from her, but without thinking, kissed her again.

"Well, you'd better get home now. Sans will wake up in an hour for his new job," winked Mettaton.

Her eyes widened. An hour?! She didn't have time to hesitate. She picked up her costume and made a run for it.

"Would you care to-"

"SNOWDIN PRONTO!"

The boat, sensing her urgency, grew legs and sprinted across the water back to Snowdin. After the boat stopped, she hopped off and ran. She ignored the fact her feet were frozen cold from the snow. She ignored her shivering breasts and everything. All that mattered was getting home. She climbed up to her room's window and climbed in. She hid her costume in her closet, pulled on a nightgown to help her feel warm, and got in her bed. 5 seconds later, she heard an alarm clock. She breathed out a breath she didn't know she was holding. She heard Sans walking out of his room. He stopped in front of her door and came in.

"If she's really not up to anything, she should be in her room, sound asleep," thought Sans out loud.

Frisk closed her eyes immediately. Sans walked in front of her and pulled the covers back. He let out a breath of relief.

"I guess she's just going through some teenage thing after all," thought Sans out loud again. He kissed her head and went to get ready for his first day on the job. He didn't notice the money next to her computer.

"I'll have to keep the money somewhere. I got lucky he didn't see it! I'm even more lucky Mettaton decided to make my paychecks under the table, meaning my paychecks come from my tips," thought Frisk.

The next few nights were like this. Frisk would wait until Sans fell asleep to go to her job, then she's rush back home just 5 seconds before Sans' alarm went off with her pretending to fall asleep every time he walked into her room and gave her a kiss on her head and he leaving for his job. She knew if she slipped up and ended up staying any longer at the dance club, Sans would check up on her, pull back the covers just in time for her to be climbing through the window half naked. She timed everything perfectly. She knew exactly what time to leave and Mettaton knew it as well.

"Papyrus' birthday is tomorrow, but he won't have his party unless Frisk decides to come! Brother, will you try to convince her to come?" asked Mettaton EX.

"I will do my best," promised Mettaton NEO.

"Thank you, dear brother."

"Anytime glamorous sis."

Right after Frisk and Mettaton's kiss session, he looked at her seriously.

She glanced at the clock. She could only stay 5 more minutes until she had to dash out of there.

"Two things I want to tell you. One, start leaving here after putting on your costume. I'll reduce the time we kiss for you to do that. Two, you're off on Papyrus' birthday. So go celebrate his birthday with him," said Mettaton NEO.

Frisk's face lit up.

"Really?! Thank you!"

"You have 3 minutes left. Change quickly and run!"

Frisk did just that. She had been working for Mettaton NEO for one week, and she's saved up to 700 gold. She dashed out of the dance club feeling light as a feather. All that guilt lifted off her shoulders. Plus she was happy that the kisses would be shorter.

"I am so over kissing that old man!" laughed Frisk as she practically flew home. She climbed up to her window and climbed in. As soon as she took off her costume, she heard his alarm ring which alarmed her.

"What? His alarm isn't supposed to ring yet! I need to make sure that tonight he stops coming in to check up on me. Wait, I know..."

Frisk flopped on her bed as she was. She was only wearing her underwear, which she never did. Sans turned the door knob and she in turn closed her eyes. Sans saw her and blushed wildly.

"When did she start sleeping in her underwear?! This is different! Why am I still here?!"

Sans quickly closed the door and got ready for work. Frisk smiled as she opened her eyes.

"That should keep him out of my room for a while."

"WHAT?! YOU'RE REALLY COMING TO MY BIRTHDAY PARTY AFTER ALL FRISK?!"

"Yes. Mettaton NEO told me why I shouldn't feel like I don't belong and the more we talked, the more I realized he was right. You're my friend, and I do belong," smiled Frisk.

Papyrus teared up from joy and hugged his best friend. Mettaton EX turned to face her brother.

"Thank you for talking to her. I figured she was going through some type of teenage phase, but I wasn't sure. But somehow you knew what to say," smiled Mettaton EX.

"Hahaha, I do have a way with words," winked Mettaton NEO.

Even though he was having a kissing affair with Frisk and enjoyed every time she looked flustered, he was enjoying seeing her all happy about being able to have Papyrus' birthday off to spend time with him and her other friends. He wasn't a jerk after all. He did want her to be happy. He just wanted to be happy too. For the next few days, during the day time, Frisk helped plan the party details, and snuck out to go to work at night.

"At least all I have to do is kiss Mettaton. It's not like he's forcing me to have sex with him. Hmm, probably because he's a robot and doesn't have those parts. So it's not so bad. Besides, I had my first kiss before I fell underground," thought Frisk.

Ever since she slept in just her underwear, Sans hadn't checked up on her in her room. At least, he hadn't gone towards the bed. He still checked on her, but in a different way now. He would only open the door, peek inside, and close it. He only checked on her to make sure she was sleeping okay. But he didn't know he was basically checking on pillows at this point. Frisk would make it in her room after Sans checked on her now. Mettaton was getting greedy with the kissing by making them last longer and grabbing her bottom, which she heavily minded. The day of Papyrus' birthday arrived. The party was set at night time to make it more interesting and fun. What gave Frisk the willies is the fact that her boss will be there. In hindsight it makes sense because he was first friends with Papyrus and he used to be friends with Frisk as well when she first fell down. He tried to fight her, and she died several times but always came back and was determined to get through to him. His fans got through to him instead of her, but she took it. Before his batteries died out he had called her a good friend.

"Frisk! Sans! You're here! Come in, come in!" squealed Mettaton EX.

Frisk peeked around and saw Mettaton NEO on the couch with Papyrus. Papyrus stood up immediately, rushed over and hugged both Sans and Frisk at the same time.

"MY BROTHER AND BEST FRIEND ARE HERE! BRING OUT THE CAKE NOW SINCE EVERYONE ON THE LIST IS HERE!" shouted Papyrus with glee.

"Okay darling!" called back Mettaton EX.

Frisk kept glancing nervously over at Mettaton NEO, her secret perverted boss. He knew she was glancing over even though she thought she was being discreet about it. When she glanced again, he beckoned her over with his finger whilst smirking. Without saying anything, she glided over and sat on the couch next to him. She felt her face heat up in embarrassment and couldn't bring herself to look at him.

"He's a gosh darned robot for crying out loud! A really old perverted robot possessed by Napstablook's cousin...Yeah, that's right. I forgot. He is a sentient being and is now corporeal since he was able to fuse with his robot body. So that means everytime we kissed, he was able to feel it," thought Frisk.

She was right. Mettaton, Napstablook's cousin, had an outburst of positive emotion so strong his soul fused with his robotic body. Everytime someone hugged him before he became corporeal, he couldn't feel a thing. Then, after he became corporeal, he could feel hot and cold things. This shocked him at first but he became so happy that he was now alive.

"I'm sure by now you've remembered I am alive in this body. So you know I could in fact feel your lips everytime. Frisk, darling, you're a fantastic kisser. I just wanted to let that out," calmly said Mettaton.

"Is your sister just a robot, or is she also corporeal?" asked Frisk.

Mettaton NEO chuckled.

"She is pure robotic. Napstablook and I don't have any female cousins or sisters. There's only 1 other family member that we know of and he too is dead but he isn't down here with us. He went towards the light," said Mettaton.

Frisk nodded her head.

"To be honest, I hate that Alphys created her. She thinks just because we have the same scientist friend that she can just call me her brother. I went along for Alphys' sake. But I really don't like Mettaton EX," said Mettaton in the coolest, calmest voice he could muster.

Frisk was beyond shocked. He always looked so happy to see Mettaton EX. He really is a great actor.

"So you were acting. Putting on a show," said Frisk.

"Yes, precisely. You're smart," winked Mettaton.

Frisk's face heated up immediately.

"Why do you want me to kiss you after every shift I work? I thought you never saw me like that and that we were just friends," said Frisk.

"I don't see you in any other way than a good friend, darling. I just want kisses. Is that so wrong?" asked Mettaton.

She felt hurt by what he said.

"You don't feel anything for me and yet you're kissing me and grabbing my butt?" asked Frisk.

"I like your body more than friendship. Not you. Just your body. You are seriously smoking hot," winked Mettaton.

"Just 11 more months then I can switch jobs," Frisk thought to herself to calm her down.

Sans came in the room, a little drunk.

"Frisk, Papyrus is about to cut the first slice of his birthday cake. Come sing happy birthday with us," Sans slurred slightly.

Frisk nodded and stood up. She felt a robotic hand graze her bottom before moving her legs to walk away. Ignoring the rage inside her, she went to the kitchen. As soon as she reached the kitchen, every single monster there, except for Mettaton NEO and Mettaton EX, collapsed. But Mettaton EX was somehow shut off. Frisk wanted to scream. She wanted to run. She turned to look at Mettaton NEO, but was startled that he was right behind her. He pushed her down on the floor and tore off her clothes.

"What are you doing? What if they wake up and see you violating me?" asked Frisk.

Mettaton smiled a smile that told her that he was responsible for their collapsing and that they wouldn't be waking up anytime soon to save her from this monster. Suddenly she smirked.

"What?" asked Mettaton, clearly confused.

"What do you plan to do to me? Kiss me all over? You can't do anything more! Your body is a robot body and you don't have a penis. So what's the point of kissing me here if that's all you get to do and you get kisses from me anyway?" asked Frisk, sounding cocky.

Mettaton NEO laughed.

"Darling, I became corporeal a year ago. When I found out I could feel things, I asked to make me a member. So you and I, we're gonna have some fun," smiled Mettaton.

Frisk did not anticipate this at all. Suddenly, she felt a burning determination. When she opened her eyes, her and Sans were standing outside of Papyrus' house when Mettaton EX opened the door and greeted them, telling them to come in. Suddenly, Frisk remembered. She pulled Mettaton EX aside.

"Don't let anyone drink any of the wine you guys bought. It's been tampered with," she warned.

Mettaton EX was aware of Frisk being a human who can reset, save, and load. So she trusted her instincts.

"Alright. I'll dispose of the wine, go to the store, and buy another couple bottles," said Mettaton EX, "than you, Frisk."

Frisk smiled. She was happy she had stopped Mettaton NEO from causing everyone to pass out.

"Heeeyyy, what're you doing throwing away perfectly good wine?" complained Sans.

"It's no good. I'm going to buy good wine since these were tampered with," said Mettaton EX.

Sans groaned. "Alrighty then."

"MAKE SURE IT'S BUBBLY!" advised Papyrus.

Mettaton EX winked at him. Mettaton NEO grumbled in his seat.

"Frisk must've loaded right when I pinned her to the floor. Damn! I really can't force myself on her. I have to make her pass out I guess," thought Mettaton NEO.

He smiled at Frisk and beckoned her over. Wanting to keep her job, she walked over and sat down.

"Hey deary,"winked Mettaton.

"Hello Mettaton," said Frisk.

"Want some party candy?" he asked.

This candy has the same drug that was in the wine. His new goal was to get her to pass out so he could drag her away and do what we wanted with her.

"No thank you. I'm saving room for the cake," said Frisk.

He cursed in his head, thinking he should've drugged the cake and anything else edible. Then, he got an idea.

"If you want to keep your job, take a piece of candy and eat it," he pressured.

Just then, her angel appeared.

"Frisk, we're about to sing happy birthday to Papyrus. Come and join us," called over Sans.

Happy, she walked over, ignoring the rage when Mettaton touched her butt. She was relieved when this time around, no one passed out randomly.

"Happy birthday to you! Happy birthday to you! Happy birthday dear Papyrus! Happy birthday to you!" everybody sang.

Papyrus blushed and blew out his candles.

"EVERYONE TAKE A PIECE!" said Papyrus.

Frisk knew she had to stick with the crowd all night and avoid being alone with Mettaton NEO. Just in case, she saved right then and there. No one saw the yellow star that appeared suddenly for Frisk to save her progress. Well, both Mettatons noticed, and both knew why. Well, Mettaton EX didn't know who was responsible for tampering with the wine in the first place, but she knew Frisk had to save right then and there.

"Hey Frisk, who tampered with the wine?" asked Mettaton EX.

"Huh? Oh, I don't know. All I know is everyone passed out except for me so I knew the wine had been tampered with," lied Frisk.

Mettaton EX frowned on the inside, but acted as if she accepted that.

"Oh okay! Thanks darling," smiled Mettaton.

"Dang it, Frisk. Why can't you tell me? What's going on with you lately?" thought Mettaton EX.

She decided she would pay extra close attention to Frisk.

The next night, Frisk said good night to Sans, and went up to her room. Mettaton EX is outside of the house in the bushes with binoculars, staring straight into Frisk's room. She gasped when she saw Frisk put on a sexy costume and climb out her window. She followed after Frisk when she ran to the river where the river person was. After the boat left, she took out her inflatable pocket raft and chased after the boat. When they arrived to Hotland, she hid her boat in the bushes nearby and ran after Frisk. She could not believe it when she saw Frisk run inside the club her brother owns. If she wasn't a robot, she would've thrown up.

"Need to call Sans," Mettaton EX said to herself as she took in deep robotic breaths.

Sans groaned. He had just fallen asleep and his phone rings. Who could be the idiot waking him up now?

"Hello?" Sans said groggily.

"It's me, Mettaton EX. I need to tell you something, please try to remain calm."
