They call him pervert, he calls himself smart
"so you called me here for this shit??" Sans asked as he eyed the liquid in Gaster's bottle.
"Yes." Sans frowned.
"after you just turned Frisk in an old lady last week..."
"Yes." Sans frowned even more.
"why....??" Gaster shrugged.
"FOR SCIENCE!!" He yelled as he slammed the bottle down. The smoke finally let Gaster see that his son was now--
"AHHHH!! HE'S A BABY AGAIN!!" Sans however kept his 14 year old mentality. He just couldn't speak. He tried to say something, but he just babbled gibberish.
'you've gotta be shitting me....I'M A FREAKING BABY!! OLD MAN, YOU'RE DEAD TO ME- anddd...he just picked me up...great.'
"Look at you~ You're back to being a baby-bones!! Oh this day is holy!!" Gaster said picking him up. Sans snorted right on him. Gaster frowned as Sans gave him a smug smile.
"You're the same demon, aren'cha...?" He said, wiping his face.
"Welp...time to take you home."
'what now...??'
"OH. MY. GOD." Frisk said covering her mouth in surprise.
"YOU ARE FUCKING ADORABLE!!" Frisk said kneeling down in front of him. Sans tilted his head, amused at her reaction.
'she's more adorable than me. hehe~...maybe i can get her to pick me upppp~?' Sans threw his arms up and babbled something. He didn't care either but it seemed to work as Frisk picked him up.
'nailed it~' He nudged her cheek with his head and Frisk giggled.
"He's such a cutie~ Awww~" Sans looked at Gaster and smirked. He stuck his tongue out. Gaster's sockets went blank. Sans then started analyzing Frisk thoughtfully.
'is it me...? or is her chest bigger...? maybe i'm just smaller...? maybeee now that i am a baby i can-' That's when Frisk froze, blushing as a tiny baby just grabbed her chest. Gaster's mouth fell open. Frisk frowned as the small baby squished. She pulled him away from her chest and frowned at him.
'heh~ don't regret shit.' He clapped cheerfully like a baby and Frisk sighed as she brought him closer again.
"How am i supposed to say no to that face~" Frisk said as Sans buried his face in there. Gaster was red in rage.
'holy shit- this is so comfortable- why didn't i try this before?!' Gaster picked baby Sans up.
"NOPE. NOPE NOPE NOPE. NO BABY PERVERTS!!" Sans frowned and scoffed he grabbed the air as he was being separated by Frisk.
'aw come onnnnn....friskyyyyy.....noooooo....' He tried grabbing the air again then he let his arms fall on his father's shoulder. He lost this fight, but the war wasn't over.
"Hey Gaster have you seen my note-book? I think i left it on the couch somewhere." Sans smirked smugly as he laid back enjoying the view of Frisk searching between the pillows. The notebook she was talking about was in his inventory. Sans chuckled. Frisk frowned as she heard his baby giggles. Gaster frowned as well and picked Sans up, that accidently made him click the item and the notebook fell right on the couch. Gaster and Frisk both looked at Sans then at the notebook. Frisk picked it up and sighed.
"You sneaky bastard...."She said snatching her notebook and walking away.
'damn...so close....' He said shaking his head. He watched her walk away and chuckled to himself. He'll manage to get her.
"COME ON BABY BROTHER!! YOU NEED TO EAT NYEH HEH HEH!!" Sans shrunk in his seat.
'why did the old man have to teach paps how to cook...' He turned his head to the side and scrunched up his face.
"NYO HO HOOO...I CAN'T MAKE HIM EAT!!" Frisk raised an eye-brow as she was leaning against the counter.
"Let me try, Papy...hey Sansy~" Sans immediately percked up at her voice.
'now we talking~. baby-bones!!' His tiny hands immediately came up to grab her hand. She giggled. Papyrus frowned.
"HOW COME HE RESPONDS TO YOU SO WELL??" Frisk shrugged.
"Well then....lovely-bones can you open your mouth for me~??" Frisk said as she was bent down in front of him. Sans blushed a bit. The view was perfect for him.
'heh, let's see the old man now~' He tilted his head and Frisk sighed. She poured some ketchup on his spoon. Sans sockets widened. Now we talking! That's quality food now! Sans opened his mouth and let Frisk feed him. The first thing he noticed was that she was gentle, unlike Papyrus and his father.
'i should have gotten her to feed me first- holy shit!! she's good with kids, alright.' That's how things worked and he wouldn't let Papyrus even try to take the spoon from her. Frisk was about to leave when he was done but she grabbed her hand. She tilted her head.
"You want up, lovely-bones??" Sans started bouncing like an actual baby.
'man this is embarrassing...but i get a free ride~' Frisk scooped him up gently and picked him up. He immediately hugged her. That's when Gaster came and stole him.
"Not today, pervert." Gaster said as he hoisted Sans up. Sans frowned. Gaster always ruined his plans...
'fuck you old man...' Sans thought bitterly as Frisk sat down on the couch and shrugged.
He was crawling on the couch towards a reading Frisk. She seemed lost in her book, which gave him the perfect opportunity. He crawled to her then on her. That's when Frisk flinched and looked down from her book only to find a small skeleton climbing on her. She giggled.
"If it isn't our little pervert...What do you need, boo??" Frisk asked sweetly. He could feel his soul flutter as she cooed those words.
'she's so sweet and gentle....jesus christ i'll die...at least i'll die happy...' He laid flat on her with his head on her chest. Bubbly laughter erupted from her.
"Guess we're going to sleep earlier than usual, eh? Come on." She hoisted him up again and started walking to her room. She put Sans on her bed and made sure he had his sockets closed. She shrugged and started taking off her sweater. Sans opened his socket, sneakly.
'holy shit- JACKPOT ALRIGHTTTT~' But something ruined his plans. Frisk only took off her sweater and was now leaving for the bathroom. Sans let his sockets close again.
'really..? so close....I WAS THIS CLOSE AND YET-..UGHHH...' Frisk came back in her pj's and laid down next to Sans. Sans frowned.
'she's just going to go to sleep like this....? no good night no nothing? i don't think so!' Sans crawled close to her face and cupped her cheeks. Frisk frowned and opened her eyes. She raised an eye-brow confused.
"Need something, boo??" Sans pouted. Frisk frowned trying to realize what he wanted. He started poking her.
"Ow ow ow ow...ok ok...attention??" She asked. Sans stopped and waited. She snorted and picked him up. She laid against the wall and put Sans on her.
"Here you go you needy attention seeker." She started humming and Sans didn't even remember when he fell asleep. However the next morning he was still with his head on her chest and he woke up to listen to her calm heart-beat. He got up and chuckled. Frisk didn't take long to wake up as well.
"What's up, pervert?" Sans looked away blushing.
"shut up..." Frisk started laughing and kissed his cheek-bone.
"Next time you tell me not to get in Gaster's experiment...? Don't just involve yourself..." He snorted.
"got'cha. also, nice ass--" But his sentence was cut out by a pillow to the face. Frisk started walking away.
"no frisk wait- buahahah!! i'm sorry!! friskkkk!!" Frisk pointed at him from the doorway.
"PERVERT! THAT'S WHAT YOU ARE!! GASTERRRRRR!! SANS IS CHECKING ME OUT AGAIN!!" Sans paled. Welp, he's in for a BAD TIME.
