Sans X Reader

Chapter 26

"(Y/n)! Sans! Wake up!" You heard Melody yell from the other side of the door. You groaned and pushed your head farther into the small gap between you and Sans. You could feel Sans pull you closer to him.

"Come on! We are going swimming today, remember? We need to buy some swimsuits!" Melody yelled again. You heard Sans sigh as he sat up.

"Alright! We're coming!" Sans yelled back. He turned to you and brushed your hair out of your face.

"Come on Babe. Time to get up." Sans stated. You groaned again and turned away. Sans sighed and grabbed your bag, finding some cute clothes and teleporting them onto your body. He picked you up and teleported downstairs.

"BROTHER! I HAVE THE MOST WONDERFUL IDEA! WE SHOULD INTRODUCE THE GIRLS TO METTATON AND HE CAN MAKE SWIMMING SUITS FOR THEM!" Papyrus suggested once he noticed Sans.

"Do you really think that is a good idea? For all we know, Undyne could be at Alphys's lab. We wouldn't want her finding out about them. The king still needs one human soul." Sans explained.

"You know, it doesn't matter too much, as long as I'm the one that dies." Frisk explained, walking in the living room from the kitchen.

"You can't die yet Frisk. We still need other stuff done first. Before you can die, I need to save Gaster, befriend some monsters, and make sure Chara doesn't take over your soul." You explained, your eyes still shut.

"We left her with Asriel again though, so we would have to get her away from him." Frisk stated.

"Actually no. Don't you remember back in the ruins when I went up ahead? Well, Asriel actually was the one who saved us from Chara. Anyway, Sans, it will be fine. We will be safe." You explained.

"Are you sure (y/n)? I just don't want you to get hurt." Sans asked. You nodded.

"My feelings are never wrong Sans." You replied. Sans sighed and set you down.

"As long as you are sure, I guess. Let me call Alphys really quick." Sans said, walking into the kitchen and taking out his phone.

Once Sans was finished, you and your friends walked out of the house and towards Alphys's lab. Sans did offer to teleport everyone but you, Frisk, and Melody all agreed that It was nice to just walk. Soon, you all reached your destination. Sans and Papyrus stood in front of you, Frisk, and Melody. Sans knocked on the door. A few moments later, Alphys opened the door.

"Oh, hello Sans. Hello Papyrus!" Alphys stated. Sans and Papyrus both said their hellos.

"So Al, you know how I said that we have some friends that we want you to meet? Well..." Sans explained, both him and Papyrus moving out of the way to reveal you and your friends.

"H-humans? Oh! You three are the humans that I saw leave the ruins!" Alphys stated. Everyone looked at Alphys with a confused expression.

"I-I have cameras everywhere..." Alphys explained, a slight blush on her face.

"Is that Sansy I hear?" The familiar male voice called from inside the lab. Mettaton came 'running' out in a box like body. He grabbed a hold of Sans and started hugging him.

"Nice to see you too Mettaton... But once again, I'm not gay...Plus I have a girlfriend." Sans explained. Mettaton instantly let go of Sans, his screen going red.

"Who is this 'girlfriend' of yours?!" Mettaton yelled. Sans got up and walked to you, pulling you close to him.

"Sans? How is she your girlfriend? You only met her a few days ago." Alphys asked. Mettaton giving off an angry vibe.

"First off, can we come in?" Sans asked. Alphys nodded and made Mettaton go sit down. She brought everyone inside.

"Ok, so do you remember our time theory?" Sans asked.

"Of course I do! It was one of your father's most amazing theories! We used to always do experiments about it. Wait...are you saying..." Alphys asked. Sans nodded.

"So there are really multiple timelines? You must be the only monster who remembers! That would also mean that your girlfriend remembers!" Alphys explained. She started to get really excited.

"Well, it's a little complicated but yes. You have no idea how many timelines I've seen thanks to this twerp!" Sans said, ruffling Frisk's hair. Alphys gave a confused look.

"I have the ability to reset timelines. I mostly did it because I wanted to see what would happen if I did something a little different...But one time was a huge mistake and I killed everyone." Frisk explained.

"Anyway, the point is, that all three humans remember, and so do Paps and I. Now, this wasn't what we came here for. We actually came for Metta." Sans explained looking at the robot. Mettaton's screen changed to show a heart.

"WE CAME BECAUSE WE ARE GOING SWIMMING TODAY AND WE WOULD LIKE YOU TO MAKE SWIMMING SUITS FOR THE GIRLS!" Papyrus explained. Mettaton robotically sighed.

"Fine. Come with me Girls!" Mettaton said motioning for you to follow. You, Frisk, and Melody all followed Mettaton upstairs. Mettaton lead your friends into a room but stopped you before you entered.

"Now listen here missy. Sans is one of the most handsome monsters here in the Underground. If I can't have him...You better take really good care of him! You will look so sexy in your new swimming suit, that no monster would be able to resist you!" Mettaton explained. You nodded your head and walked into the room.

Noon soon arrived, and your swimming suits are finally finished. Frisk put hers on. It was red with a bit of frill on the top part to show for her lack of breasts. Melody's was just a normal, orange bikini. Yours however, was a really tight fitting (but comfortable), neon blue bikini. It was tight enough on the top section to make your breasts look bigger than they actually were. The bottom section was like a normal bikini bottom but had a skirt covering it.

"You look absolutely BEAUTIFUL darling!" Mettaton stated. You smiled, a slight blush on your face.

"Alright! Let's go get your men and let's go swimming!" Frisk cheered. You and your friends left the room after saying thank you to Mettaton. You found Alphys at her computer.

"Hey Alphys! Where did Sans and Papyrus go?" You asked. Alphys looked up from her computer.

"They left a few hours ago. Here are the directions to the lake they went to." Alphys explained, handing you a piece of paper. You knew it was Sans who wrote this because it had his handwriting. You thanked Alphys and headed out the lab.

Once you arrived at the lake, you saw Sans there with nothing but shorts on. You had a small blush on your face. You never saw Sans without his jacket on, and you found him kind of sexy like this.

"Pappy!" Melody yelled, waving to her man. Papyrus and Sans turned towards you and your friends. You could see a faint orange blush on Papyrus's face as he waved back. Sans's face, however, was fully blue as he stared at you. You giggled and walked up to him.

"Hello! Earth to Sans!" You teased. You waved your hand in his face.

"(Y-y/n) You l-look... a-amazing!" Sans stated. You smiled and kissed his skull. You then run into the cool water. You went far enough so that your hips were under the water. You went to turn back to face Sans but water was splashed at you.

You let out a surprised scream and looked to see who splashed you. It was Sans. He burst into laugher. You smirked and splashed him with water as well. You started to run to more shallow water. You heard the splashing of Sans running behind you.

The others were doing their own stuff over a few yards away. Sans kept chasing you and splashing you with water. Suddenly, your fun was interrupted. A light blue spear flew straight towards you. Sans luckily was able to stop it.

"Hello... Undyne." Sans stated, just as the fish monster walked into view.

(Hey guys! Sorry It took me so long to post this. I had it done but I just haven't had the wifi to it. And when I did have the wifi to do it, I was either busy or just plane out forgot! Well, here it is! Bye bye for now!)
