(Sans x Reader) The one you call home

||Chapter 5: The Undying||

As you walk through the new environment you couldn't help but smile at the sights. Small glowing blue stones light up the sky, illuminating the lake and grass. The reasoning behind your presence was forgotten, through your journey you pass only the most remarkable sights. You walk through what seems like a hallway, only to find dark green grass looming over you, the sight is almost intimidating, your throat tightens as you suddenly feel compelled to phase into the unknown. You flinch at the feeling of light strands graze up your leg. You suddenly spring up as the ground beings to vibrate. You look around for a clearing, curious as to what violence is causing the sudden eruption. You peak above the land of green, you cant see much but pitch-black silhouettes, your eyes squint, attempting to piece out the unidentified figures. Your eyes widen as one of the figures begin to speak.

"HELLO UNDYNE! IS THERE SOMETHING THE GREAT PAPYRUS COULD DO FOR YOU?"
The voice booms, your mind clicks knowing exactly who this is.

P-Papyrus..?
My mind is a blur.
What is he doing here? Who is Undyne?
My thoughts go blank as I hear their conversation.

"Papyrus, I've been informed that there is a human in your possession."
You flinch at the sudden mention if your appearance.
"Hand them over to me now so I can take their soul."

My eyes widen.
T-take my soul..?
My breathing suddenly speeds up as the skeleton leaves. I find myself having a small panic attack.
The voices around are incoherent.
Unable to hear, see or speak.
I was able to fall into my knees.
Causing the world to stop. Going silent.
Until a wave of sound crashes to me.
"WHO IS THERE?"
You shudder as the voice screams.
You felt the world shake, more and more as it moves closer.
You roll your eyes towards the sound.
A cyan spear is illuminated through the grass.
"FOUND YA PUNK!"
Soon, the bright light zooms towards you.
You freeze and hold your arms in front of your face
Heh, like that will do anything..
Suddenly, a blue light fills your gaze. You look up to see a familiar skeleton holding up a wall of bones. His eye set ablaze in a blue and slightly yellow flame. His gaze is soon set on me with a concerned expression.

"y/n? oh my god, are you okay? are you hurt?"
The concern in his voice shifts into a disappointed and angry tone.
"are you crazy?! what are you doing here!?"
His arms on your shoulders, still showing major concern for you. You slightly blush at the sudden thought.
"Sorry... " you mumble.
Sans gives you a comforting look, his expression changes as he looks at the spear wielding maniac.
"SANS WHAT THE HELL ARE YOU DOING!? PROTECTING THAT THING."
You slightly shudder hearing their words. You felt familiar boney arms wrap around you.
"heh, sorry undyne, this things off limits."
A wave of blue washes over you causing your mind to turn. You fix your gaze up at your unfamiliar surroundings.
"Where are we..?"
You were stopped by the sound of chuckling.
"this is one of my favourite places in waterfall, take a look."
You step in front of the skeleton, your eyes widen and a gasp of awe escapes your lips.
It was dark but everything was lit up by the stone stars in the sky, ahead of you and Sans was the most beautiful castle, something from a Disney movie. You take a step towards the castle. Nothing but void sits below you, you felt a hand grasp your arm
"jeez, careful, I know it's beautiful but it's not to die for. "
You sigh in relief as Sans pulls you away from the edge. How many times is he going to keep saving you?
You really are pathetic..
You felt a tear meet your eyes, you pull them back.
Sans is sitting on the edge with his eye sockets closed. You join him and let out a sigh. This is nice.
You dangle your legs off the edge and swing them lightly. Sans eyes lift and lock onto your leg.
"hey, what happened there?"
You lift your eyebrows and follow his gaze, onto the scars that Flowey left you. A constant reminder.
You shudder at even the thought of his name. You look at Sans, hesitant to speak. His eye lights are dim, his expression is filled with worry. He relaxes a little, giving you a kind smile.
"y/n, you can trust me, I won't force you though."
You smile, he's right, I can trust him.
You look back at Sans and begin to explain the events of the flower. The more you explain, the darker his expression gets. You finish your explanation to hear Sans muttering to himself.
"stupid weed... gonna kill him...son of a b*tch.."
You let out a small giggle, Sans' eye light suddenly return, as well as a blue tint on his cheek bones.
"welp, legs go, knowing Pap he'll want us home."
You nod as he holds onto your arm. The tint of blue grows.
"hang on"
He says as he does his casual wink.
Another wave of blue washes over you.
You find yourselves back at the skelebros house.
"pap! we're home!"
Papyrus' head pokes out of the kitchen.
"AH BROTHER! YOU HAVE A GUEST THAT EAGERLY WANTS TO SPEAK WITH YOU."
The curiousity fills your head, as you and Sans to face each other. He's wearing the same curious expression.
"NGAHH!!"
A loud scream erupts from the kitchen, causing you to yelp. Sans' stiffens as he puts his arm in front of you protectively.
A tall blue fish rages out of the kitchen. Her eyes are familiar. Speaking of, her eyes lock onto you menacingly and switch back to Sans.
"PUNK, WHAT DO YOU THINK YOU'RE DOING PROTECTING A HUMAN!?"
She beams as she tells at Sans, Papyrus seems to have flinched while Sans stood still.
"what do you think you're doing undyne."
Sans spoke, obvious hints of anger in his voice.
"WELL I WANT THEIR SOUL, OBVIOUSLY!"
You step back, terrified. Well who wouldn't be.
Sans turns his attention to you, snapping you out of your sudden space out. His eyes reassure you, relaxing you. Sans turns back at the fish-who you figure is undyne- yeah the same undyne with the spear.
Sans' eye sockets are now pitch-black.
"over my. dead. body."
Your eyes widen and grab onto Sans.
"What are you doing!?"
I whisper-yelled at him
He stayed silent.
A large maddening grin appears on Undynes face.
"So be it."
Your eyes fill with fear, causing you to shout.
"Guys what are you doing! Don't fight! Just, talk it out or something!"
All eyes we're locked into you, an awkward silence fills the room. A loud laugh breaks the silence.
"FHUHUHUH, YOU SERUOUS PUNK!? TALK IT OUT. PLEASE. EVERYONE WOULD BE HAPPY IF YOU WERE DEAD."
That sentence. That one sentence broke you. You shake the tears from collapsing onto your face.
Sans immediately runs and looks at you.
"y/n don't listen to her, okay? no one would be happy, not Paps, not Tori"  He hesitates..
"not me.. "
You open your mouth to  speak, however, the conversation between Papyrus and Undyne interrupt you.
Wait, was Papyrus keeping his voice down?
A voice breaks the silence.
"ME? FRIENDS WITH A HUMAN!?"
Undynes eyes light up in fury.
Papyrus sighs.
"GUESS I OVERESTIMATED YOU UNDYNE, GUESS BEING FRIENDS WITH THE HUMAN IS TO MUCH OF A CHALLENGE FOR YOU"
The goofy skeleton spoke loudly, wearing a smile across his face.
"WHAT? BE FRIENDS WITH THIS TWERP? EASY!"
Undyne gives you a determined glare. You're worried about the outcome. You look at Sans, who seems to know exactly what you're thinking.
"you'll be fine bud."
You nod at Sans' statement, only to feel unusual hands grip onto your shoulders.
"COME ON PUNK! I'M GOING TO BECOMES YOUR BESTIE! FUHUHHUH!"
The mighty fish screams with enthusiasm as she drags you to the kitchen.
"Nothing has brought me and Paps closer than cooking!"
~~~~~~~~~~~~~~~~~~~~~~~~
After the uhm. "Cooking lesson"
You and Undyne actually bonded quite a bit. You had some laughs, especially after she spread tomato all over the walls.
"You know I actually had a lot of fun, Undyne!"
She looks at me and smiled
"Yeah you're not that bad, punk. About before, sorry...I guess."
You gave her a soft smile until she spoke again.
"You know, Sans seems to care a lot about you.."
Her eyes lock onto yours, her words causing you to blush a deep red. Her smile widens
"That sack of bones? Really?"
The red brightens at the mention of him.
A familiar blue light appears behind you
"hey, you ladies having fun?"
The grin on Undynes face widens."Yep! Me and the punk are cool now, I actually got to go! See ya punk!"
The fish sprints out of the house, breaking the door down as she leaves.
"UNDYNE! NOT AGAIN! SANS GET THE SPARE DOOR FROM THE ATTIC!"
A puzzled look forms on your face.
"Spare door? Does this happen often!?"
Sans lets out a small chuckle
"heh, yep. nothing new. Undynes' a door-k"
Laughter erupts out of me, followed by a annoyed groan from Papyrus.

"SANS OH MY GOD, NOW IS NOT THE TIME. JUST GET A DOOR!"
