What if? (Sans x Reader)

How it all started #1

In a house with two floors lived three girls. Mia, Victoria and (Y/n). The first floor there was a living room, kitchen, and a dining room between the two other rooms. In the living room there was a black couch with red and tan couch pillows, a large flat screen TV and a tea table in the middle, there stood some old newspapers, a mug and some roman noodle cups with some noodles still inside and some poured over to the side. The kitchen looked kinda like a bar place, the wall were half up light blue half down white, many equipment was the same light blue since it was (Y/n)s favorite color and she was the one that did most shopping of the housewares, Victoria and Mia did the food shopping, but they mostly bought junk food, they only cook when guests are over, so the kitchen is almost always clean. In the dining room there was a big glass table, maximum of 8 people could sit around it, but just like the kitchen, it doesn't get much use, there is a cape of dust over the table. Upstairs there are four rooms. One of em is Mia, Victoria and (Y/n)'s room, they wanted to stay in the same room so there was more space in the house, also they like to be very close sometimes, in this room there were two bunk beds, there was Mia's and Victoria's bed,they switched up and bottom every day, the first one to go to sleep would get the top one, and then the other one is (Y/n)'s, but instead of a bed being underneath there was like a little desk were she did most her drawings, science sketches, books, and science book journal were she kept all the things she studied every day, it has information of every single experiment she has done or been to so far, and (Y/n)'s computer that was given to her by her boss, the room walls were covered in different posters of different video games, animes or bands that they liked, so the wall wasn't that visible, the floor had laundry all over it. The other two rooms were guest rooms, they both looked kinda the same, A twin bed with a night stand a medium size flat screen TV and one of em had its own bathroom. The forth room was a play room, it had a pool table, ping pong table, table games and card games. There was a large bathroom at the side of the stairs, it had a baby blue tub, it kinda had the same styles of the kitchen, half blue half white.

One day Mia was playing Undertale on (Y/n)'s computer, she restarted and renamed Chara, she started to meet with Sans after sparring Toriel, but the words he said weren't the same as always, she shrugged it off, maybe a new update or so many times of playing the dialogues would change.

"Mia? What are you doing?" (Y/n) yelled from downstairs.

"Playing Undertale on your computer!" Mia yelled back, "Say, was there an update? Cause all the words are mixed up? The dialogues aren't right!"

In the game Sans was walking you through the gate thingy but stopped in the middle exactly when Mia stopped talking.

"I dunno, I'm not sure maybe Torri did it!" Her voice was getting closer. "Why don't cha ask her when she comes back from work?" (Y/n)'s head popped out from the door frame.

"Yeah okay, okay what are ya doing?" Mia asked while she waited for Sans to move. "Watching anime?"

"What? Noooo, totally not." (Y/n) went back downstairs and watched anime.

"Tsk tsk, I caught you again" Mia said in a funny tone.

"Yeah, yeah" (Y/n) turned the volume of the TV a little higher.

"What is wrong with this game? Why isn't Sans moving...ugh maybe the computer froze." Mia was about to shut the computer until Sans turned to face the screen, like when he tells his puns, he turns to the gamer, frisk does the same. "What the...."

"Kiddo...have you wondered what's under this bridge? It just seems I dunno, just wanted to stop and look at it for a sec. Let's go before my bro comes." Sans said.

"Oh shi...that scared me for a second...totally not creepy at all." Mia chuckled awkwardly.

"Heh...kid quick behind that uhh....conveniently shaped lamp." Sans said to frisk. This continued until Papyrus got tired of Sans puns, Mia groaned every time he told a pun. Once paps left Mia murmured 'finally'.
