[Undertale] Sans X Reader - Repeat, Eternally

Yandere!Sans and Yandere!Papyrus [83 Followers]

I'll be doing Gaster x You soon, don't worry. Also, there'll be a Grillby x You as a bonus later on, but this was requested! The actual story will be continued on Friday. [Yes, I know, so far away!] But I'm sorry ; n; between school and job, I just don't have the time to post like I was before! Thank GOD my E-Learning course had nothing for me today! I would have gone INSANE if I couldn't write. Warning: Lotsa blood.~

Yandere!Sans x You

You sat outside of the party, sighing. Everything you were didn't really seem all that necessary now, with Toriel gone. Asgore and Asriel had decided to leave you alone for the night, and Undyne and Alphys wanted to take Frisk. 

You leaned further against the railing of the porch, and you heard someone come up behind you.

"It's a beautiful night, isn't it?" Sans asked, his hands in his pockets. 

"Yeah, it really is." You stifled a sob. You'd probably be with Toriel right now, had she not have died on you. You knew she wouldn't have wanted you to remain like this.

Sans put a hand on your shoulder, and you felt something wet. You were wearing a ballgown of sorts, in an attempt to match the festivities. You glanced to whatever it was, and saw red. "Ketchup, again? Seriously, Sans?" 

"Uhhh, yea. Somethin' like that." Sans grinned. "Hey, uh. I know I've been a real jerk." 

"Yeah, you have." You muttered, moving a lock of your hair out of your eye.

"So I've done somethin' real nice, to make up for it." Sans wiped the ketchup from his bones, right onto his sweater, and offered you his hand. You hesitated, but took it. He guided you to the door. "Before we open this door, I gotta say... I love you, ______." 

"Sans...." You were almost mute by his confession.

"I can't stand seeing you in pain.... So I fixed it." A dark smile crossed Sans' face, and his white pupils dissipated. You froze. That look was full of bad omens.

"What do you mean, you fixed it...?" You say, a nervous smile crossing your face.

"Well, I took away anything that would remind you of Toriel, ________." He chuckled. "It was really difficult to make it a surprise, but I did it!"

You pushed open the doors with haste, and what you saw caused you to slump to the floor. You let out a distressed moan, and then a scream, and then began to cry.

Blood, everywhere. Staining the walls and floor.

Your friends, all dead. Lying around. You let out another scream. "No, no, no, no, no!" You cried, reaching for Asriel.

"You see...? I fixed it." Sans chuckled. 

In horror, you looked at the stain he had left on your shoulder. 

It wasn't ketchup. 

"Oh god, oh god oh god oh god..." You clawed at your arms, breathing raggedly. 

"I killed everyone that was in your way of bein' happy, darling. Even Penelope. Don't you see how much you mean to me?" His words stuck in your mind, but you couldn't do anything. You couldn't move. All you could do was cry. "This isn't usually something I'd do... but I was gettin' sick of sharing you..."

No, no, no....oh god, no...

"Now we have forever...and we'll spend it right here, together, in this room for eternity..."

Your mumbles and cries mixed together as y ou los t y o u   r m i    n d

Yandere!Papyrus x You

"Sans!" You hugged Sans, wrapping yourself around his fluffy sweater.

"Yes, babe?" It had been years since Toriel's death, and the original Sans had always been there for you. He had cleaned up his act, and even if he had been a jerk, you knew he never meant to be. All he had been was upset at you, and you couldn't really blame him. You were, after all, prepared to sacrifice your future to save everyone...and that was unfair to him. He didn't make you choose that. He would have stayed with you... but everyone else would have, too, and you didn't want to deny them their freedom.

"Merry Christmas.~" You say, smiling. Yes, your 4th Christmas together. Papyrus was always cheerful, each time around, but it had been dimming. Could it be because he and Mettaton were having an extremely rocky relationship? 

"Merry Chri-" Sans' eyesockets went black. Red ketchup dribbled from his mouth.

"S....Sans....?" You asked, reaching for him....as he burst into dust. 

It was like Toriel all over again.

The person standing behind the dust cloud was the last person you'd expect to be wielding a knife. It was Papyrus. You were unaware of your own screams as he straddled you, and covered your mouth with tape. You began to cry.

"Christmas...after Christmas...after Christmas. You never noticed me. You never noticed my feelings for you." A dark, almost insane look crossed Papyrus' face. "Until now, Sans always had you, Sans always got what he wanted, even when he hurt you." 

You whimpered, and Papyrus held the knife against your cheek.

"I didn't like that. I loved you, and you never noticed. I loved you so much, and you just ignored my love!" 

The knife went into the carpet, inches away from your face. You attempted to struggle, but it was meaningless. Papyrus only laughed.

"But now, you have no choice. You have to notice me, don't you? Now that he's gone."

Papyrus laughed. "You and I are going to be together forever...~ Now that there's nobody else in the way." 

So wow. Uh, I'll update later with Yandere!Toriel [Not Romantic] and Yandere!Gaster, maybe even Yandere!Grillby, or Yandere!Undyne?
