A crazy baby scientist
"Hey Gaster i need to borrow some wires for a robot i want to build--" Frisk froze dead in her tracks. She looked at the floor and blinked in surprise.
"Noooo...." Frisk said, snickering. There was a sleeping Gaster baby on the floor. He was sleeping in his lab coat. Frisk covered her mouth and looked at the adorable baby skeleton.
"awww!!" Frisk picked Gaster up and he woke up, confused.
"What the- ...Frisk...??" But all it came out was babbling. Frisk giggled.
"Hi~ Gaster! Awwww! Who's a cute baby~" Gaster frowned.
"Baby..? What the hell is she on about- OH MY GOD I'M A BABY!" Frisk saw the panic on the baby's face and started rocking him.
"Shhh...It's ok..." Gaster's sockets started feeling heavy.
"Damn it....she's good with kids....can't....stay...awake...." A small snoring sound came from Frisk's shoulder and she smiled.
"Thank God we went shopping that one time...Or THIS would have been a disaster."
Sans was howling with laughter at the sleeping Gaster baby.
"NO WAY! THAT IS MY DAD?! BUAHAHAH!!" Gaster woke up again and scrunched his face up at the volume of his son's laughter. He groaned. Frisk's eyes widened and she picked Gaster up. Sans shut up looking at the baby with a jealous look.
"You woke him up, Sans!" Frisk said, frowning at Sans. Sans blinked in surprise and his mouth fell open at how she was baby-ing Gaster. He felt jealous. Gaster smirked.
"With this...I can hog Frisk for all day without seeming suspicious! Sans will be so jealous! heheheheh...It's the best plan! Don't worry my flower, today you can spend the whole day with dad!"
"I THINK FATHER IS CUTE AS A CHILD!" Papyrus said. Frisk giggled as Gaster was now hugging Frisk. Sans growled. Gaster looked at him and stuck his tongue out doing an L shape with his thumb and finger. His son's sockets went blank and he knew it was a success. This day couldn't get better.
Gaster was sitting with Frisk and they were playing some dumb patty cake game. Gaster however was frowning.
"I don't get what's happening...Stop!!!" Gaster put his hand forward and Frisk didn't do anything. Gaster looked relieved. Then she put her hand against his again and he frowned again. Frisk laughed. Sans was sitting in the arm-chair and his leg was bouncing in annoyance.
"hey frisk?" he said, but Frisk ignored him. He blinked in surprise as she didn't answer. Gaster looked at Sans and smirked. He gritted his teeth.
"friskyyyy...??" He asked again. Frisk giggled as Gaster put both hands on her cheeks.
"You're such a cutie." She said grabbing Gaster's tiny hands. He smiled at her and babbled. Sans started tapping his foot and put his hands together in front of his mouth as he inhaled and exhaled.
"baby-bones...??" He tried one last time. Frisk gasped and Gaster laid on top of her.
"Awww!" She said. Sans sockets went blank. His father was seriously stealing his girlfriend.
"friskkkk...??" He whined. Frisk looked at him.
"Yes boo?" He sighed in relief as FINALLY Frisk payed attention to him too. Gaster was put down on the couch. She sat up and looked at him.
"i want a kissss..." He said. And it was true. He was jealous and needed attention. Frisk giggled and got up.
"Fine fine....Come here you big baby." She sat down on his lap and was about to kiss him when Gaster opened one of his sockets.
"Oh no you don't! My Frisk!" Gaster started crying. Frisk froze and looked back. She sighed and got up to pick Gaster up. Sans was left hanging. His sockets went blank again. Did his father just...block his move...?? Frisk was rocking Gaster. She looked at Sans with an apologetic look and walked with him to the kitchen. Sans eye started flaring. It was on old man...It was on.
Frisk was playing with Gaster on the carpet and Sans was watching her. He didn't mind. She had gentle moves. His imagination can work with the slightest moves she did. From swaying her hips to- Ok how the hell did he get to thinking of that from her playing with his father in baby form.
"Awww~ You're just the most adorable thing!" Sans chuckled. She really was great with kids.
"friskkyyyy i want attention too!" Frisk gave him an amused look.
"Don't i give you attention daily?" She said, raising an eye-brow. He pouted.
"yeah but--" Suddenly he got interrupted by Gaster babbling.
"Pfft- Yes Gaster?" Frisk said, looking back at the baby. Sans snarled. Gaster winked at Sans and then started playing with Frisk again. Gaster however threw something under the couch accidently.
"Aww...What did you do..?" Frisk slid on her stomach and started searching. Sans looked down and smirked. Gaster's sockets widened.
"OH NO YOU DON'T!" Sans eyed the baby and frowned. It was clear that his look was one of 'Don't you fucking dare'. Gaster inhaled and started crying. Frisk her head and immediately slid out. She groaned.
"Man you're a handful...I'm right here you attention seeker, shhhh..." Frisk picked him up. Gaster calmed down and narrowed his sockets at Sans. Sans sat up with his eye flaring in rage. Gaster smiled mischievously and flipped the bird at him over Frisk's shoulder. Sans mouth fell open. This can't keep happening.
"ughhhh just eat you annoying baby..." Sans said crossing his arms. Gaster gave him an unimpressed look. Sans shrugged.
"i'd be nicer if you weren't stealing all the attention from my girlfriend, you know?" The last word he said with his finger in Gaster's face. The baby didn't hesitate to bite. Sans cursed and immediately moved his hand.
"you little-" Frisk coughed from the doorway. Sans froze.
"amazing....baby...father...umm...hi frisk..." He said, sweating bullets. Gaster snickered. Frisk came in the room and took the baby food and the spoon from Sans. He put his hands up in defense and pointed at Gaster.
"he started it." Gaster spurted, frowned and pointed at Sans. Frisk face-palmed.
"You both are awful. Come on Gaster." She bent down and fed him, gently. Gaster's eyes widened in pleasant surprise and Sans couldn't help but snort. He was in that spot too before. Frisk is really good with kids. That's when Frisk's phone rang. She hissed.
"One second. You feed Gaster again, ok?" Frisk gave him the stuff and ran out to answer her phone. Probably Luka calling since he always had a problem and loved to call Frisk. Sans sighed and looked at Gaster, crossing his arms. Gaster mimicked the look and pose.
"can't you just eat it yourself?" Gaster raised a bone-brow in a way of saying 'where's the fun in that?'. Sans sighed.
"good point...fineee..." He took the spoon and tried again. Gaster spat right in his face and threw the food right in his face and on his clothes. His eye started flaring. Gaster smirked and opened his mouth. Sans sockets widened as he realized what was happening. He lounged forward and covered Gaster's mouth. Gaster licked his hand. Sans immediately moved it and shuddered.
"that's so gross...ew..." he said, wiping his hand. But it was now too late as Gaster started crying. Frisk came in the room and looked at the two in shock.
"What the hell happened here?! I was barely gone for two minutes!" Frisk picked up Gaster who was now hugging her. Sans almost wanted to throw his father off the roof.
"he started it!" Sans said again. Frisk looked at him unimpressed. Sans opened his mouth to say something else when Gaster started babbling something and pointing up.
"Uhhh...You want to go to bed...??" Frisk asked. Gaster shook his head. He pointed up again.
"A bath...??" Frisk asked, hoping a bit that wasn't the answer. Sans sockets went blank as Gaster nodded.
"Uhh...Sans...do skeleton kids have-" He raised his hand.
"not until the age of 7, no." Frisk sighed in relief.
"Guess i can give him a bath then." Sans spurted and looked at Gaster who was smugly looking at him.
"i'll help...need to clean myself up anyways." He said with a shrug. Frisk snorted and looked at him with a sly smile.
"Hope you don't also expect me to bathe you as well." Sans face lit up. Gaster shook his head in disbelief at Frisk. She chuckled.
"Come on already." She said as she gave Sans Gaster and started walking. Sans watched her for a moment and then he looked at Gaster and flipped him the bird. Gaster growled and started poking him in the sockets and nasal cavity. The whole way up the stairs they were fighting.
"Let's clean you up then." Frisk said as she raised her hands and started taking off her sweater. It was warm and humid in the bathroom. Sans changed and washed his face. As he was wiping his face his eyes fell on Frisk as she was taking her sweater off. The tank-top was a bit rolled up, showing her abdomen. Gaster noticed Sans staring and splashed him in the eyes.
"ah! fucking-" He said, wiping his sockets. Frisk giggled.
"He just wants to play~" Sans snarled.
"that demon thing would never..." He said as he finally lowered his hands. Gaster babbled innocently. Frisk knelt down next to the tub and started helping Gaster. Thank god he was probably 2. Frisk was about to about to get the shower handle off when Gaster accidently splattered water on her and OH BOY didn't Sans get a nice view through her damped tanked top. She really was growing in size huh...? Sans felt his face heat up and Gaster looked at Sans with a face that was in shock. He immediately started crying. Frisk looked down at her tank top.
"Nooo...Baby, it's ok! You didn't mean it-" Frisk sighed as Gaster didn't stop crying and got up to leave and change. Sans narrowed his eyes at Gaster. Gaster chuckled at him.
"if you 'accidently' drawn in a tub...is it really my fault?" Gaster's sockets widened and Sans started slowly creeping towards him. That is until Frisk came back and opened the door. Sans and Gaster both looked at Frisk who was blinking in the doorway.
"i just wanted to help..." He said, sweating bullets. Frisk beamed at that.
"Really?! Great! Here is the body wash!" Frisk gave him a bottle, smiling and then kissed his cheekbone. Gaster narrowed his eyes at the now older skeleton.
"You may have won this round...But the war isn't over- BLEAGH! DON'T WASH MY MOUTH WITH THAT SHIT!" Gaster said, flapping his hands around in discomfort. Frisk giggled and rolled her eyes at the two. She knew they were fighting on her. It was just too fun to watch.
Sans was alone with Gaster as Frisk was going to the bathroom.
"i am TIRED of your shit...you have been hogging frisk...all....FUCKING...DAY!" Gaster smirked. Sans growled and then pinched the bridge above his nasal cavity.
"so that's why i went to extreme measures..." Gaster raised an bone-brow amused.
"i called kat over...you'll have to choose between kat and frisk." Gaster's mouth fell open as the door-bell rang and Frisk was going to open the door. Sans smirked.
"check mate old man." He leaned back smugly with his hands behind his skull as Kat entered. Frisk and Kat were now talking and Kat rushed over to Gaster.
"Awww! Look what your tiny genius brain did! Hahahah!" Gaster couldn't help the blush. This was utterly embarrassing. Frisk smiled.
"Oh Frisk! Please do sit with us!" Kat invited Frisk. Sans shook his head in disbelief. Gaster beamed and looked at Sans smiling. Frisk chuckled and as she was about to say yes Sans pulled her soul with blue magic.
"no! mine! take the baby! she stays! thank you!" Frisk looked at Sans amused as he was nuzzling her neck. Kat started laughing and Gaster was narrowing his eyes at Sans.
"Oh no you don't...I'm taking both!" He started babbling and pointing at Frisk. Kat chuckled.
"Guess he wants us both, huh?" Frisk got up from Sans hold and picked Gaster up, Kat's hand still lingering on him. He looked at Sans over Frisk's shoulder and made an L shape, sticking out his tongue, with his fingers. Sans was mad now.
He was angry. He just wanted Frisk for himself for at least 1 minute...EVEN A KISS WAS OK. But noooo Gaster had to be a cute baby. Fuck that shit. He teleported in the living room where Kat and Frisk were now camping with tiny baby Gaster. Papyrus was doing his homework or something. Papyrus had barely left the room the whole day anyways. poor him had a test tomorrow. He didn't know as much as Frisk and Sans. But right now he didn't care. He needed to steal Frisk. And that's what he did. He teleported inside the room and picked Frisk up, bridal style. Kat started laughing as Frisk yelped.
"SANS! PUT ME DOWN!" He snorted.
"hell no. see ya later, kat." The woman waved as Sans teleported with Frisk in Frisk's room. He teleported right on the bed and he was being the big spoon in the hug. Frisk scoffed.
"Why'd you do that...?" Sans growled a bit thinking about it.
"that old man has been hogging you the whole fucking day. now shush and let me get my girlfriend for a minute, ok? k cool." He closed his eyes as he hid his face in Frisk's hair and she started laughing.
"I know baby, i know..." She said turning around and kissing him. He almost let it turn into making out until-
"wait hold on what do you mean that 'you know'??" Frisk smirked and crossed her arms.
"You think i didn't see that you and Gaster have been going at each other's throats the whole freaking time?" Sans blinked an frowned.
"you knew?! then why the hell didn't you do anything?!" Frisk giggled.
"It was fun to watch." Sans frowned and flushed bright blue.
"that isn't fair!" Frisk started laughing even more. Sans then got mad and pinned her down.
"apologize right now." Frisk stuck her tongue out and Sans leaned down to kiss her. The door opened and Papyrus was standing in the doorway.
"...WHEN I WAS THINKING I NEEDED HELP WITH BIOLOGY I DIDN'T MEAN THIS...GROSS." Frisk spurted as Sans fell off of her and the bed with a grunt. Papyrus closed the door after them and Frisk couldn't stop laughing. Great...He made a fool of himself the whole day. But hey it was worth it. He finally got to stay with Frisk. Next day however Gaster was a blushing mess. Frisk and Sans looked at each other and smirked.
"He slept with her." They both said, fist bumping each other as Gaster was getting coffee with milk and sugar instead of black like always. Yup...he was in the ninth cloud alright. Papyrus narrowed his sockets.
"I'M STUCK IN A LOVERS NEST AND YOU ALL WON'T EVEN TELL ME HOW KIDS ARE MADE...SHAME ON YOU ALL!! NYEH HO HOOO!" Papyrus said as he got up and took his bag to get to his test.
"Good luck on your test! Don't forget to text me if you need help!" Papyrus groaned.
"I WON'T CHEAT ON MY TEST! NYEHHHHH!" Sans snorted.
"suit yourself she's got great anatomy- i mean she's good at anatomy!" Gaster smacked him over the head and he sighed.
"deserved that one...oops..."
