Littletale! Sans x Child! Reader

No one's POV
"C'mon guys were almost there!" Said (Y/N) while running. Then you stopped so the others could catch up. "You are a fast runner." Said Gaster while trying to carry Sans and Papyrus at the same time. "You actually did (Y/N)! We can finally leave!" Asgore ran up to (Y/N) and hugged them. "Friendship hug!" Papyrus yelled. Everyone ran to (Y/N) and gave them a big hug. "Well what are we waiting for lets go!" Undyne yelled and ran out. "Wait for us!" Everyone yelled in unison.

They were all out and saw the sunset. "Isn't beautiful guys?" (Y/N) asked curiously for what they think about the sunset. "It's so pretty. Is like this all the time?" Asked Toriel in awe and what is going on in front of her. "Yes it does but at the end of the day. Later it goes away and you can see the beautiful night sky. You will see stars and the moon." You explained to everyone. "Really? I will finally see the stars?" Sans asked excitedly. You turned to him and nod. "Thank you (Y/N) we are now on the surface and I can finally see real stars. Thank you." Sans said while hugging you and crying tears of joy. "Don't cry." (Y/N) said calmly.

Sans stopped crying and let you go. "Well lets go guys before it gets dark." Gaster said a bit worried. "To late!" Papyrus yelled. It was night time now. It was very beautiful. Then a bunch of stars could be seen in the sky. Everyone was in awe again. Especially Sans. "It's beautiful. It's like how I imagined it will be but better." Sans said happily. "Lets go now." Gaster said. We all moved along. They walked where (Y/N) grew up even though they are all the same age except for Gaster. Some people saw them walk in. They were all surprised you were still alive and freed the monsters. "(Y/N) my baby. You're back!" Your mom ran to you crying. "Mom? Mom!" You yelled and ran up to your mother.

"I thought I would never see you again ever since you fell in the mountain." (Y/N)'s mom said while crying and hugging her baby. "I missed you so much mommy." Said (Y/N) doing the same as her mother. They both pulled away and wiped away their tears. "Mom, I would like you to meet my friends. They helped me when I fell." "Well anyone that helped my baby is a friend of mine. What are their names?" Your mom asked. "The tall skeleton is Gaster. The skeleton that is wearing red is Papyrus. The skeleton wearing blue is Sans. They both are brothers. The goat is Toriel while the other is Asgore. The fish girl is named Undyne. Right next to her is Alphys. The robot is Mettaton. And the ghost is Napstablook or Blooky." Said (Y/N). "Well welcome to the surface. You can live with me and (Y/N) until you can find a house to live." Your mom said happily. "Really? You would do that?" Said Gaster. Your mom nodded. "Lets go!" (Y/N) yelled. They all followed.
(Just saying you don't have siblings. You live with your mom and that's it).

A month later

The others found a place to stay instead of living in (Y/N)'s house. It was also near Christmas. Everyone is outside playing all bundled since there is snow and it is cold. "Hey (Y/N). I still can't thank you enough that you saved us from the Underground. You made every monster very happy." He said while blushing. He developed a crush on you since you were nice and energetic. "No problem. Also I became friends with everyone. I wouldn't just fall and leave by myself." (Y/N) said with a happy face. Sans blushed more. "Hey punks. You guys want to have a snowball fight?!" Undyne yelled. Sans and (Y/N) nodded. They all battled against each other. They were all having a great time.

Christmas day

(Y/N) told everyone to come to the hill they had a snowball fight. Later they all came seeing presents next to (Y/N). They all looked confused. "I know you might not know but today is Christmas. It is the time of year where you give presents to each other and appreciate what you have in life. I got you all gifts." You said happily. You walked up to Gaster. "Here is a telescope so you can see the stars maybe even see some planets." (Y/N) handed him his gift. You moved to Toriel. "I know you like snails and like to cook so I got you a book about snails and a cook book." You handed her the gift. You moved on to Blooky. "I got you headphones so you can listen to music." You handed him his gift. You moved on with Undyne. "I got you a sword, shield, and a helmet. I know how much you like to fight." (It's fake). You her the gift. You moved on with Alphys. "I got you a science book and a science kit." You handed the gift to her. You moved on with Metteton. "I got you a microphone so you can act like a star." You handed him his gift. You moved to Asgore. "I got you flower seeds, a shovel, and a bucket for watering your plants." You handed him his gift. (The bucket to water your plants. It kinda looks like a tea pot). You moved to Papyrus. "I also got you a cook book but the recipes are how to make pastas." You handed him the book. You moved on with Sans. "I got you a huge bottle of ketchup and a joke/pun book." You handed him his gift.

They all looked so happy. "Merry Christmas guys!" (Y/N) yelled. Then they all tackled you in a hug except for Gaster. "We love you (Y/N)!" They all yelled in unison. Then they all played except for you and Sans. "Thanks (Y/N) for everything." He said while blushing again. "Sans whats that blue thing covering your cheek bones?" (Y/N) asked him. "N-Nothing!" He stuttered. You then hugged him. "You're so cute." You said while snuggling on his hoodie. This caused him to blush more. "You're so cute (Y/N). When I grow up I'm gonna marry you." He said while looking at you. You smiled and continued to hug. Sans hugged back. (Y/N) pulled away. Then Sans kissed her cheek and hid in his hoodie. (Y/N) giggled and kissed his cheek. Sans almost fainted. "This is the best day of my life!" Sans yelled with glee. But Gaster recorded the whole thing so he could make fun of Sans in the future.

Well that's the end. Sorry if there wasn't much contact with you and sans. I got writer's block and I had a different story line but I changed it meaning it took me longer to think what should happen next. So I'm so sorry if it sucked. Anyways I will be taking requests. Also oh my gosh!!! We're almost at 100 views for this story. OMG!!!
