Yandere!Gaster X Reader: My Beautiful Experiment

chapter four: escape

"Sans it's time fore testing so there's no point in you fighting me" Gaster said not affected at allThe two were scared beyond belief. What testing was he putting them through this time?! Sans held Papyrus closer to him, his little brother shaking like a leaf. "Why can't you just leave us alone," Sans yelled through all the hatred and the tears, "why are you doing this to us?! Does the fact that we're your sons not mean anything?!" Sans temper was getting the better of him but he didn't care so he continued, not realizing the things floating in the air around him or his eyes flashing colors. Papyrus's eyes flashed as well. but little did they know their combined magic was effecting a certain reactor. Causing sirens to go off! Gaster's eyes widened as a Gaster Blasters appeared before him. this was bad. If they set that off while the reactor was overreacting with his soul connected it was gonna-BOOM! Gaster disappeared. the place seemed to be falling down.Sans looked around and picked up papyrus before running to where they heard Y/N. When they got there they saw that she was asleep so he didn't test on her but he did knock her out. Breaking the glass he and papyrus carried her out of the lab just in time for it to fall apart Looking around they saw nothing around them but endless trees fro miles around, that and lots of snow. Where the hell were they? Where was everybody? Surely if they looked hard enough they would find people to help them right? . . Right? Papyrus was afraid of their new surroundings, the giant trees loomed above. Looking sinister. Ominous. "S-sans I'm scared. Where are we," he asked huddling closer to his brother and the sleeping y/n resting in Sans boney arms. She was surprisingly light. Which was strange given her age and what not. Had Gaster not been feeding her well? papyrus then asked, "Is she going to be alright?"Sans didn't have a clue if she'd be alright but paps didn't need to be scared and worried "yeah bro she'll be fine and once she wakes up we can all live together how's that sound paps?" Sans asked the younger skeleton.Papyrus's eye lit up in childish delight, "Really?! So we'll all be like a really big family?! With that thing people call a 'house' and stuff like 'furniture' right?! I'm so excited!" He then went into that cute childish rant he always did that lightened Sans mood. y/n as if sensing the touching moment smiled in her sleep and snuggled more into Sans for warmth. "Heh yeah paps and y/n will be our big sister and she can make puzzles with you and pasta" sans said as they walked until they reached a town called 'snowdin'papyrus was delighted by the news asking questions like, "What is this stuff falling down? Is it supposed to do that? Oh! Oh! And look it's all over the ground! What is that white stuff Sans? it's really cold isn't it? Why is Y/n shivering Sans and why isn't she waking up right now? Is she tired? Should we wake her up?"Sans chuckled "I don't know paps and I think we should find a place where she can sleep" sans looked around before finding a building that said 'snowdin inn' 'huh creative name' sans thought sarcastically before catching papyrus' attention "hey paps I think y/n can sleep there let's go 'inn' shall we?" Sans just couldn't help himself from saying at least one pun.Papyrus groaned loudly, "Uuugh! Sans whyy?!. . . But I agree! Let us go!" He fist pumped the air victoriously taking the lead, since it was 'clear' he was the leader in this. In his mind he had elaborately saved not only Y/n the sleeping princess but also with his trusty knight brother at his side. Sans couldn't help but smile at his "Nyeh heh heh" shouting brother, cutely marching along in whatever this white stuff was to the front door. Once they got there a rabbit lady was sitting at the desk before she realized the state y/n was in. "OH dears you all look so tired come I'll lead you to a room that you can stay in and I'll bring you up some cinnabunnies" the rabbit was very kind and lead them to a huge room. "Now just wait here"The rabbit said as she walked off to grab them some cinnabunnies and hot chocolateThe brothers were confused. Sans was suspicious. NO ONE was this nice to them. They just thought Y/n was some freak miracle occurrence. But just maybe they couldn't help but feel hope that there were others out there. Like her. Ready to help. Papyrus just smiled while taking a seat looking at his brother as he bounced around on it, "What is this thing? It feels nice! And it's not hard at all! You should try this Sans!" but a lud gurgle was heard from the young skeleton's stomach. He blushed bright orange. Sans chuckled, "Don't worry Paps. She said she'll be bringing us something called cinnabunnies. You'll be fine." Sans really hoped whatever this hot chocolate and cinnabunnies was, was actually some sort of food. he was hungry as well.The rabbit came back smiling "here you go dears. Be careful with the hot chocolate it's hot and I put the girls in the microwave so that it doesn't get cold" she handed sans and papyrus the cinnabunnies and hot chocolate "if you need anything just come downstairs" she said before leaving the roomPapyrus drank from the cup after blowing. . . really hard. But he was really happy. He was literally bouncing off the walls because this my dear friend was his first introduction to the wonderful world of sugar and caffeine. Sans could only watch with wide eyes as he bounded around the room like some kind of dementedly cheerful rocket. 'Mental note,' he thought to himself with sweat trickling down his skull, 'keep away from Paps.' With all the noise paps was making it woke y/n up "w-where am I?" Y/n asked looking around d before seeing sans looking shocked and a blur which she assumed was papyrus "paps?"She couldn't help but giggle at the sight watching him bounce a round with childlike wonder. Sans couldn't help but smile at her face. It reminded him of Papyrus. Noticing Papyrus was probably going to knock something off the walls she caught him with a giggle, "Gotcha~!"Nyeheh the great Y/N has caught the great papyrus!" Y/n smiled at him "sans what got the great papyrus so hyped up?"He shrugged, "I dunno. We just ate and drank this stuff and he went bouncing off the walls. . Literally~" That caused the both of them to crack up. Laughing lightly she hugged Papyrus closer to herself as she examined her surroundings. "Where are we? How did we get here," she asked looking at them a bit worried, "A-are we safe?" She wasn't tortured for as long as them, well not consciously, but her first experiences with Gaster were enough to give anyone nightmares. So it was understandable."Yeah the building is collapsed and vaster is dead I think" sans said if only sans knew that wasn't true. Y/n let out a sigh of relief "thank goodness" y/n shivered at the thought of gasters smirk. "Y/n y/n! There was this white stuff all over the ground and falling from the sky! It was also cold too do you know what that was?"Y/n thought for a minute, but a sudden sharp pain in her head stopped her from remembering. She dimly remembered throwing the white stuff at Asriel once. But she doesn't know what it was called. "Umm. . I'm sorry I don't remember," she said hanging her head in shame before perking up brightly, "but I do remember it's fun to throw it at each other! And that it's cold. . . I think?"Papyrus turned towards sans and y/n "let's go and play in it!! Race you there!" Papyrus took off leaving y/n and sans stunned for a moment before they smirked and ran off after papyrus. Unbeknownst to them that a certain skeleton was watching them from the void.
