Unexpected ★ (US Sans x Reader)

Alphys

You entered Water fall, this is where Alphys lived. You see papyrus in his post. You wave towards him. ''Hey Y/N, how's it going?''

''Um..................good, what's this place called?'' You say. Water rushes every where, crystals and gems sparkle in the dim light.

''Waterfall, this is where Alphys is. Your gonna fight her soon, so how much have you learned?''

''Well....'' You start off with, '' My soul represents durability, and my attacks are diamond shards.'' Papyrus looked at you calmly. ''Durability huh, cool.'' You tell papyrus that you will talk to him later, and with that you head off.

You get to a meadow with flowers, and you see a figure approaching. You ignore it until is starts to run up to you, ''HUMAN!!!!!''. 'On no' you think in your mind 'That must be Alphys'. You run away from the figure. You enter a battle.

Axes swing at you from all directions. You continue to run into an area called hotland. Your phone rings and you pick it up. Alphys seems to stop so you can answer your call. Huh. The voice on the other line was sans.

''Hello Y/N!!!! How are you, and where are you, did you beat Alphys?''

You look at Alphys, who is just standing there waiting for you to finish the call. You tell him that you are fine, and that Alphys is chasing you.

''WAIT WHAT?!?!?!?'' he says nervously. You reassure that you are fine. You say goodbye and hung up. You put the phone in your pocket. Alphys starts chasing you again. You cross a bridge and she collapses. You panic little bit, then you see a water cooler. You take a cup of water and pour it on her head. she groans a bit and gets up. She eyes daggers at you and leaves. You stand there. You walk up to a lab, which has a fish lady in it. She sees you and introduces her self.

''H - hello, I'm Undyne I did not expect any company, w-what's your name?''

'' My name is Y/N''

Undyne and you became friends when you mention an anime. You both were talking about Manga, and collectables when your phone ringed. ''I'm sorry Undyne, let me take this call.'' You pick put the phone to find out it is Sans.

''Hello Y/N, me and Papyrus want to know if you can have dinner with us.'' Something you don't know is that Sans is blushing a lot on the other line.

''Oh, sure Sans, I'm at Undyne's right now, ill be over there in about, 45 minutes, okay?''

''Okay, bye Y/N!!!'' Sans also says something really fast, you could not hear it then he hangs up. You continue your conversation with Undyne for a little longer.

You start to head home. You enter waterfall, an gaze upon the crystals. You see Alphys talking with Sans. You walk up to them. Alphys sees you. She does not death glare you anymore. Probably the fact that Sans is there. She runs up to you and picks you up, slinging you over your shoulder. She runs somewhere with Sans following her, stars in his eyes. You keep yelling ''WHERE ARE WE GOING?'' but they ignore you.

She goes into a lizard shaped house, which you can safely assume is her house. She turns toward you, ''WERE GONNA MAKE TACOS, AND THERE IS NO BACKING OUT OF IT!!!!!!!''. Sans had gotten out ingredients, and pots and pans. 3 Aprons, and one spatula. He throws you an apron that has strawberries on it. Alphys has an apron with scales on it (guess what color 030).Sans has an apron with blueberries on them. You put on yours and look at it again. Sans runs toward the stove and throws a pan on it. Alphys takes meat and ripped it out of the package, throwing the unthawed meat in the pan. You just stare in shock. Sans jumps to get the rest of the things and throws it at Alphys. She catches them and slams them on the counter. She pushes you toward the stuff. '' KARATE CHOP THE LETTTUCE'', she says . ''FILL YOUR BODY WITH ANGER, THEN RELEASE IT AT THAT WIMPY VEGETABLE''

You pause. You think about what would have happened if you never fell here. Lexi would be happy. You never would have met amazing people. Anger would go on. Anger. Its filling your body. You scream, your soul summons on accident. Diamond shards are sent at the lettuce.

oops.

You look at Sans and Alphys. Alphys is looking like she seen someone who died and came back to life. Sans is bouncing and cheering. Aww, cute. Alphys snapped out of it. ''Impressive punk!'' she said. You smell smoke. You look over to see the pan with the meat on fire. You panic as the building catches on flames. Sans picks you up and runs out of there, as well as Alphys.

''I'm sorry about your house, Alphys!'' Sans says while hugging her.

''Its okay, sans!'' There was a ringing coming from Alphys phone.

'' A-ALPHYS OMG ARE YOU OKAY YOUR HOUSE BURNED DOWN!!!'' Undyne screamed from the other line. ''Hey Undyne, I'm okay!!!''

Undyne sighed in relief, ''o-okay, can you send Y/N over, I need to test something out.''

''Okay, bye Undyne!.'' Alphys turns over to you, '' Undyne wants you in her lab, she said she needs to test something out, or that's a code word for lets watch anime.'' You giggled and started to walk to Undyne's place.

'' Hey Y/N!!!'' You turned around to see Sans running up towards you. ''Yes, Sans?''

''I was wondering if I could come with you, Papyrus is still at Muffet's, and I don't like being alone.'' He said looking at you. ''Oh, sure!'' You gave him a soft smile and proceeded to Undyne's. You put your hands in your pockets.

''So what do you think Undyne is gonna test?'' Sans said.

''I don't think she's gonna test anything, she probably said that instead of saying that she wanted to watch anime with me.'' You yawned.

''Are you tired?'' Sans says with curiosity. ''kinda, I've been running around all day, and I did not sleep that well last night.''

Sans blushes a little bit before asking,'' do you want to get on my back?'' You look at him blankly, then get on his back. You lay your head on his shoulder, and take a small nap.

                                                                         ~ Sans's P.O.V~

Omg, she is on my back right now. I blush like crazy. I enter where Undyne's Lab is and I knock on the door. She opens it and welcomes us inside. She sees my flustered face. ''Hey S-Sans do you have a crush on Y/N?'' She asked me. Undyne can keep good secrets. I nod my head. ''T - That's cute!'' She said, ''c- can you wake her up, please?'' I nod again. Undyne goes to get some papers, so I rest her on some chairs. I lightly shake her awake. She opens her beautiful E/C eyes. I blush a bit, but wipe it off. She sits up, using me for support.

''o-okay, lets do this!!!'' Undyne says with enthusiasm.
