Valentines Gifts...and Pranks

"WHY DID NO ONE TELL ME IT'S VALENTINES TOMORROW?!" Undyne said panicked at the girls sitting down. Frisk was reading a book and Alphys and Toriel were painting their nails. 

"Oh yeahhh...I forgot it's tomorrow. Hehe." Frisk said flipping the page. Undyne grabbed Frisk by her shoulders. 

"WHAT?! DON'T PULL THAT CRAP! We need to get a gift for Asgore so Toriel can give it to him, i need a gift for Alph, she needs one for me and you need one for Sans!!" Frisk blushed. 

"W-who said i'm getting one for Sans?!" Toriel giggled as Alphys jumped up looking at Undyne asking about what gift she wanted. 

"Duhhh! I did! He totally likes you!!" Toriel said smiling. Frisk frowned. 

"N-no he doesn't!!" Undyne scoffed. 

"You're more clueless than Asgore with Gorgette!! Come onnn, punk! Use your brain!! You've got it for a reason!" Frisk frowned. 

"He doesn't like me..." Frisk said. Undyne rolled her eyes. 

"But do YOU like him..?" Toriel asked hopeful. Frisk blushed and looked away. 

"Even if i did it doesn't matter. He only sees me as his best friend and...i'm more of a bother for him.."

"F-Frisk-sama..I-i d-don't think that's true! S-Sans a-always lights u-up when y-you come i-in!" Undyne nodded. 

"Not to mention, he always gets jealous of MK when he tries to kiss you or to get close to you! Remember the mistletoe??" Frisk blushed. 

"T-that was nothing!!" Frisk said hiding her face with her hands. Toriel giggles. 

"Even i admitted to them i like Asgore! You have no chance!" Frisk rolled her eyes. 

"So we need Valentines gifts and outfits!" Suddenly a pink ghost came. 

"Did someone say...OUTFITS~~? Well darlings, i can help with that!" The girls looked at each other then at Frisk. She groaned and signed for the ghost to go on. 


"Sans..? You're a coward!" Asgore says as him, Sans, MK, Naptsablook and Papyrus are sitting at a table. 

"why..?" He asks confused by the sudden accusation.

"It's clear you like Frisk! Yet you're not doing anything about it!" Sans started blushing like crazy.

"YO! HOLD UP!" MK tried to protest. 

"Not now MK." Asgore said raising his hand. The armless kid watched in disbelief the conversation going down. Sans was looking at the prince. 

"..i didn't know he likes Frisk.....hehe......" Said Napstablook. Sans brother got excited. 

"REALLY?! WOWIE BROTHER!!" Sans was cursing life right now. 

"..kill me.." He pulled the hood of his jacket and hid inside. Asgore rolled his eyes. 

"Sans. You need to take responsibility and own up to it! You two are already acting like a couple!" Sans stared at him in disbelief and so did MK.

"wait...we're acting what now?? i think you've done a mistake here, flower boy." He says, frowning. Asgore chuckles. 

"At least I've admitted i like Toriel. You're not even admitting it!" Sans looked down. 

"what if...i'm just breaking our friendship...i..i like what we have...and i think it would be great if she liked me back but...i..i don't know..." Sans said looking down and sinking into his seat. Asgore sighed. 

"What a coward." Papyrus nodded and so did Napstablook. 

"I am perfectly ok with him not saying anything! I'm confessing to Frisk soon!" Sans shot up panicked. 

"you're...what now?! tomorrow?!?" MK nodded proudly. 

"Yes sir! Tomorrow! Anyways guys I was going to say i'm going to buy her a gift soo...see ya!" Mk left and Asgore grabbed Sans by his collar. 

"We.Are.Getting.Gifts.Today! ASAP!" Sans frowned. 

"i..i don't know what to get he--" He stopped. He knew what to get her. Frisk has always been a hopeless romantic apparently. He groaned and let his head fall on the table. Asgore chuckled. 

"Now come on!!"


The mall they were in was newly built in the Undergound for touristic purposes but...The monsters used it a lot since a lot of the buyer's spread around the Underground and some new ones FINALLY were in one place. Some of the stores also had modern things now. No more gear ready for war. 

"This...is actually not so bad!" Frisk says looking at herself in the mirror. She was happy with the hoodie she choose for valentines, some jeans and a hat she got. She also had a checkered red shirt around her waist, still keeping the rainbow suspenders however. Alphys pushed her glasses up. 

"I-i d-didn't expect F-frisk-sama t-to pick something t-that matches." Frisk gave her a 'really dude?' look. Alphys then looked at Frisk. 

"C-could y-you p-pick something for m-me t-too Frisk-sama??" Frisk gestured with her finger for Alphys to do a twirl. She looked through the clothes in Muffet's shop. 

"Hmmm...I think this red dress..? It's kinda baggy...oh oh oh! Perfect!" She picked the dress and took a red ribbon and a red head-band with a red rose on it. 

"There you go Alph!" Alphys looked surprised. Toriel came out of one of the dressing rooms as Alphys went in. Frisk looked her up and down. 

"Hmmm...doesn't say something new to me...Head high Toriel." Toriel looked confused at that. Frisk nodded. 

"You have such good complexion for purple. No doubt! Size?" Undyne looked dumbfound. 

"I...don't know..?"

"Hmm...I'd go with a 6 or..?...Maximum of 7, take a six, we get a bigger size if it's not good for you." Frisk said looking around. Frisk actually enjoyed fashion. She loved the science behind it, so to speak. The girls just didn't use it, that's what bothered her. They wouldn't let her choose or speak, not even with make up, when she was actually better at it. 

"Yo, why do we always dress her up by forcing her instead of taking her shopping like this. She's got eye for fashion. She put Mettaton to shame." Mettaton was floating in the corner. 

"I KNOW!!! It hurts, but i am impressed!" Muffet giggled from behind the counter. 

"You know dearie, if you ever want to help me, i would be more than glad to let you help. i will even pay~" Frisk smiled. 

"I will think about it. OH PUT THAT DOWN RIGHT NOW METTA!" Frisk said as he was about to pick an eye-catch glittery pink that would make you feel neon-ly nauseous. No better description. Frisk looked around after she handed a cute white and lilac dress to Toriel with a cute ribbon. 

"Here Toriel, try this one. Metta what size do you have?" Mettaton looked at himself and Frisk frowned. 

"A 5..?" Muffet nodded from behind the counter. 

"My my, dearie~ you've got quite the eye~. Here's my card." Frisk gladly took it as she spotted something. It was a coat that Mettaton would KILL in. 

"YES!" She said as she rushed to it. She gave it to him and gave him a cute accessory for it too. Alphys and Toriel both came out the dressing room. Frisk rushed to Alphys side. She frowned. 

"Two sizes smaller..?" She looked at the spider lady. The lady nodded and went to the back. Frisk took the ribbon from the small lizards hands and put it around her waist. She pulled a bit. 

"Too tight? Uncomfortable?" Alphys shook her head.

"Breath for me?" Alphys breath in and out and Frisk nodded. 

"Too tight. A longer one. Hmm." She started taking ribbons and comparing them. She eyes Toriel and frowned. She took the ribbon from Toriel's head and looked around. She got a very nice clip instead. It looked like a purple diamond. Toriel admired herself. Frisk liked more casual cloathing, like the ones she was wearing now. The others however wanted to look fancy. Undyne jumped up. 

"Do me next! ngahh!!" Frisk didn't even think twice as she gave Undyne a nice shirt with a vest and some trousers to match it. Suddenly she got a text from Asgore. She was confused. 

| *Hey Frisk. You are good with clothes right? What do you think i should wear?

You should probably wear something with royal purple. Toriel's dress is lilac ;)*| 


"Apparently Frisk is good with clothes." He said surprised as Toriel and Undyne were sending photos of Frisk checking the size of Alphys dress with her fingers. Sans snorted. 

"you kidding..? she always was, she just never gets to show it. she prefers comfortable clothes anywa--" Sans stopped as he looked at the photo. Frisk was in her outfit from tomorrow. Sans blushed. 

"Hehe." Asgore said looking at his face. He gave Asgore his phone back and rolled his eye-lights. 

"HEY BROTHER. YOU SHOULD DRESS TO MATCH FRISK'S OUTFIT!" Papyrus said. Sans frowned. How was he supposed to match that...? 

"I will be honest. I don't really care about matching colors. I care more about matching styles right? If i were to wear a cool hoodie for some holiday...the person i'm matching with should wear, i don't know.... jeans, a vest-type of jacket and a buttoned up shirt?...Hey!! That could work nicely! I'm such a genius!!"

"got it." Sans said with a smile, remembering Frisk's words from a few days ago when they were playing pokemon on DS together. He tried it on and seemed good. They finished quickly and Sans ushered them to the store with gifts. Sans however had something else in mind. He had, after all, a bag of 50 G.


"Frisk! Move faster will you?!" Undyne said. Frisk shook her head, with a sigh. 

"Don't worry, i'm looking." They were in an random store with a lot of video games and stuff like that. She needed to get to the candy store and she also wanted to get something from here. She will get him a few games for the console. She found:I Expect You To Die, Last of Us 2 (since he owned the first one), Operancia: The stolen sun, Valkyria Chronicals 4, Echo, Ys Origin, Oddworld: Abe's Oddysee, Uncharted 4. Frisk smiled as she gave the shop-keeper her money. It was a beauty how much you could buy with 50 G when dollars started coming into the Underground as well. She started putting sticky notes on each game and only leaving the first letters of the games. It spelled: I love you. It was childish, she knew it. But she wouldn't dare to tell him in the face. They also went and bought some Valentines day chocolate. Frisk decided she will stick inside some puns. 

'i know you'll like my gifts. how? choc it up to experience.'  

'I love you dairy'

'He had an uncandy feeling that he was being watched. Why..? Dunno, i'm probably in my room'


Sans bought her a box of chocolates, yes. A bouqet, absolutely (he avoided buttercups at ALL COSTS)...he remembered she liked lilacs, so he got just that, and he also bought her a bracelet. It was a golden bracelet with a red and blue stone..Why he chose that? Because her soul trait was determination and his was patience. This meant a lot to monsters. Man he was a hopeless case. He...he was scared but like, a good type of scared? Giddyness was what it was. He kinda like it. He always felt life threatening scares when it came to humans...because well...Chara. But with Frisk? He always had this...weird feeling.

Asgore of course got Toriel a bouqet with a hidden message in it and a poem attached to it and Papyrus was overly excited to see Frisk's reaction for his gift. 


And there they were. Sitting in front of each other, matching, gift in hands, everyone watching. 

"Yeahh...i'm not doing this with all of them watching." Frisk said looking around.

"secret place?" Sans said with a half shrug.

"Abso-freaking-lutely!" She took his hand and they teleported away. They were now in the echo-field not far from their school grounds. 

"so uhh...y-you look nice..." Frisk smiled. 

"You do too!! not that you don't usually look nice, of course not...oh god...." Frisk said awkwardly. She sighed and started laughing at herself. 

"I haven't been this scared of something since Megalovania started playing on my ass in the Judgement hall." Sans snorted and they both sat down. They looked at each other's gift and both started chuckling as they exchanged gifts. Frisk was first. She smiled when she saw it was dark chocolate. They both hated chocolate that was too sweet. They loved a 70% dark.  They would share them when they did homework or played together. She then saw the bouquet of lilacs with a little note: I lilac you. Frisk giggled as red crept up her cheeks and then she opened the small box. She stopped. 

"o-oh my god! Sans!!" She said pulling the bracelet out. 

"It's so...wait...how did you--...." She stopped realizing he used the money from her poker game. On Christmas they both got G's from Gaster but now-...? 

"no....You didn't...Oh my god!!" Sans started chuckling as he turned almost as blue as the echo flowers around them. 

"yeah...i thought you'd like it.." Sans said rubbing his neck awkwardly.

"Like it?! You kidding me..?! I LOVE IT! Thank you!" She said putting it on. It was Sans turn.

"guess it's my turn...HOLY- these are so many games!" Frisk chuckled. He didn't understand why there were sticky notes on the games until he aligned them all in order and he read the message. He pulled the hood of his vest. 

"damn it...that's...that's smart-!" He sighed and looked some more. He read the jokes in the chocolate box and they started both eating chocolates next to each other. 

"soo..uhh....does this make us..?" The skeleton asked a bit confused.

"I don't know...do you want it to make us...?" Frisk asked confused as well.

"uhh...i...i don't know..." He said as Frisk blushed looking away. 

"I...i'd kinda like that..." She said, a bit quieter. Sans looked at her. 

"y..you'd do...?" Frisk nodded blushing more. Sans blushed as well. 

"guess we are..uhh..together now...?" Frisk asked. 

"yeah..." Frisk looked at Sans. 

"N-nothing will change...right...?" Frisk asked, scared. He pulled her in a hug and kissed her forehead like how his dad used to do to show affection. 

"nothing will change...maybe only for the better..." Frisk smiled and the two of them stayed in the fields a little longer eating chocolates, making puns, and planning their next prank. And guess what..? Their next prank was at the teacher's presentation for Valentines...after an awkward rejection.


"I LIKE YOU FRISK!!" Was the first thing she heard as the two teleported back. Frisk's eyes widened. They had no classes but they were however asked to stay in scool. Frisk rubbed her neck awkwardly. Sans put a hand in front of her. 

"back off, mk. i was first, sorry." Frisk smiled a bit in apology and Mk understood. 

"oh...but can we still be friends?" Frisk smiled and nodded. 

"Of course!" Sans narrowed his sockets. 

"Ok now...real question...YOU GUYS TOGETHER??" Yelled Undyne. Frisk and Sans looked at each other. The pause was enough to send all the girls squealing and circling around her like vultures. They asked so many questions Frisk was backing away and bumped into Sans. 

"woahhh there. you ok??" He asked. Frisk nodded and smiled. 

"yeah, sorry!" Suddenly the teacher's called the students from the bigger classes and the teachers in the festivities hall. Frisk looked at Sans he took out his phone and he smirked and winked at her. Time to have some fun. They sat down and the teachers had their little talk about love and stuff and put a song they expected, since they put it everytime they took a break from any event or talk they had in this school. 

"Here's a little song I wrote
You might want to sing it note for note
Don't worry, be happy" You could hear playing from the stereos until the sound of a bluetooth connected came on. Sans brought his phone to his mouth as he opened the microphone app and started singing:

"I fucked these bitches and I'm fucking all these hoes
Eating pussy like it's Oreos
You already know I, you already know" Everyone from their class looked at Sans, apart from Frisk who was casually sitting. Suddenly she pushed her hat up and sat up taking Sans phone. 

"You already fuckin' know bitch, ayy!" Everyone's faces fell as Frisk started rapping and Sans started hyping her up.

"FRISK?!" Everyone of the people she knew said as she got up with the phone and Sans got up as well. They wanted to show they were guilty for this.

"Oh. My. GOD! THIS WILL BE GOOD!!" Gorgette said.

"BUAHAHAH!! THEY'RE SO IN TROUBLEEEEE~ AFTER THISSSS~" Undyne said and Alphys nodded, agreeing.

"Oh these two are something, alright." Toriel said as Asgore snorted. She gave him a look and he looked away shrugging. Frisk took in a deep breath and started rapping fast, so fast that it left everyone in the audience dumbfound. Did she need to be good at everything? The two trouble-makers started dancing and gesturing to emphasize what she was saying. 

"Got all this paper, I don't go to class
Shorty look good with that double-stuffed ass
Shoe made of gator, so I'll see you later
Ya' boy made the fader, all yo' shit is trash, uh
She only a five in her face
So her head get a bag and my time don't get waste, uh
Give me a time and a place
And I'm pulling up fast 'cause my tongue like the taste
Ooh, how do you do that?
Keep my shit wavy, like Durags
Make me your ex-man, like Hugh Jack'
I can't be your boo, I'm a douchebag
Got so much drip, you kids might need a hoodie
Said I'm out here buzzin', but I got a woody
I been in the field, but I feel like a rookiе
And I eat that pussy like milk's favorite cookiе" They both were dancing at this point. The others in class started dancing as well. The teacher's were trying to stop the song, but they couldn't. The kids from other classes were laughing and vibing as well. Sans took the phone back and started singing just as he saw his father give him a thumbs-up. The man must have been as bored as them.

"I fucked these bitches and fucking all these hoes
Eating pussy like it's Oreos
You already know I, you already know, I, I, I
I fucked these bitches and fucking all these hoes
Eating pussy like it's Oreos 
You already know I, you already know I" Frisk added an 'Ayy' as she took the phone back. Sans chuckled at her excitement. 

"have to agree they are sounding good." Gaster said nodding. Misses Doods looked at him in disbelief. 

"MR.GASTER!"

"You already know, ayy
Pull up in a robe, ayy
Pink as shit, I steal his bitch
She ride me, rodeo, ayy
Water how I flow, ayy
Coke all in my nose, ayy
Stack it quick, I'm getting rich
You see me do-si-do, ayy
Bitch, what do you mean I can't see a titty?
And I'm whipping out my peen in the middle of the city
And I'm rocking Nike, but the fit is looking shitty
I can't hit that bitch 'cause I just been so busy
She grab on my dick and say, "This little piggy"
While out in public they say, "You Shotgun Willy"
Just call me the kid, got a tattoo of Billy
I want my nuts kissed from a bitch hot as chili, huh?
You already know though
Why all these motherfuckers want a photo?
Kiss my homies on the mouth, I'm a homo
Pulling up, iced out, feel like Frozone
I been bagging all these bitches, like I'm Frodo
Catch me whippin' out my dick like a yo-yo
And her man is a bum, he a hobo
Matrix in the whip going slow-mo, woah yo', oh no" Frisk took a deep breath and everyone was silent, apart from Sans who seemed unphased at the speed she just rapped in. He got used to Frisk aspiring to do things. She loved tongue-tying raps and riddles.  

"I fucked these bitches and fucking all these hoes
Eating pussy like it's Oreos
You already know I, you already know, I, I, I" Suddenly the two troublemakers started singing together. 

"I swear...these two dumbasses are made for each other." Undyne said face-palming. Alphys was chuckling. 

"I think t-they're c-cute t-together!!" The two looked at each-other and smiled. 

"Ship!" They both said hugging. 

"I fucked these bitches and fucking all these hoes
Eating pussy like it's Oreos
You already know I, you already know" They high-fived as their classmates cheered. 

"i should have known they would pull something...." Gaster said face-palming. 

"I kinda feel like we should let that one slide since everyone enjoyed it..." Misses Doods said giggling as the kids laughed and cheered.

"It had been settled then...we're forgiving them...But they will still get one day of detention for the awful language." Gerson said and everyone cheered louder. Frisk started laughing and hugged Sans. 

"i'll take it." Sans said laughing as Frisk was jumping up and down for getting away with that. After the students started leaving and it was only them left to leave, Sans kissed Frisk right on the mouth which left her frozen and blinking a few times in a haze. Then she looked at him surprised and started laughing, both of them blushing. She flicked him in the forehead. He chuckled and took her hat and put it on his head. 

"Sooo...we're skipping detention, right?" Frisk asked getting up. 

"ohhh yeahhhh." He said as they took their bags and left. Oh boy, this felt nice.
