Yandere!Sans x Human!Reader

Okay..?

You were walking down the village in Snowdin. Everybody was treating you kindly, but you were scared by a bat, screaming at you with worry in its eyes as it flew away....

(That's weird...) you thought to yourself.

"Hey Y/N! You wanna walk with me?" Asked sans.

"Sure!" You agreed.

You and sans were walking through the forest, when sans immediately stopped in his tracks. 
  You asked, "Sans what's wrong?" 
    Sans just looked forward. He then turned to look at you, but he wasn't looking at you with his smile and his snow white eyes. His eyes were ice blue and he wasn't smiling like what a normal person would. He approached you, pulled you, and kissed you. The moment he crashed your lips into yours, your heart blasted. You could feel the love running through his lips. It was beautiful until he let you go and by then you were a tomato and then whispered, "Sans? Why did you have to kiss m-" before you could finish, sans pulled you to another area in the forest. He stood in front of you and asked, "Y/N... Do you love me?" You nodded in agreement and with that answer, Sans moved to the side to show you something. You smiled at sans and then looked in front of you. You gasped and started shaking...

    You saw red snow. On top of the snow was Toriel, Her head was chopped off with her eyes gouged out, her fur, blood red. Have facial expression before death screamed brutality. Her body was even worse, blood was soaking through her shredded dress. She had lots of cuts on her body and her limbs were dismembered. Her fingers didn't look like fingers anymore. The cut was so deep you couldn't help but see her bones. Her hand was still clutching something even after death. It was a family picture with you And frisk in it. You could barely see anything because of the blood.
    Then there was Mettaton. His body was dismembered and his pink heart turned to black. There in the patches of crimson was everyone you loved. Alphys, Undyne, Asgore, Flowey, and,
P a p y r u s.... 
It looked like papyrus was the one that suffered sickly murder than all the others. His head was bashed in all and his smile was covered in a liquid that you didn't want to describe. You felt like you were going to puke. You looked at one last body...
F R I S K. 
    Her head was also chopped off and her saves were all deleted, which made her bodu disappear. THAT WAS IT. You knelt and You puked and cried and sobbed. You were broken. Poor Frisk. She was dead and you didn't save her. She was your family, your soul. But a filthy psycopath killed her... You were

To find the killer. Sans then whispered in you ear.

"No worries Y/N, they were in the way of our love~"

You stay kneeling.

You turn to look at sans and tried to move away from him but he summoned a wall of bones to block you. Sans got to his knees and crawled towards you. He purred, "Now you're officially mine Y/N~". 

"What?" You gasped.

"I threw away your plate for you because you would see a decapitated head. Unfortunately, Frisk saw and then told my brother. They soon had a BAD TIME."

    Sans grinned and kissed you forcefully and you tried to move but you just couldn't. Sans then whispered lustily, "You're about to have a Good Time sweetie~." You froze. You kicked sans away from you, "No sans, No! No don't do it!" Sans grabbed your wrists and pinned them above you. He was kissing with force and lust. You felt his warmth across his body as he continued to pin you down. He straddled you and was playing with the edge of your shirt. You cried as you pleaded for mercy. It shouldn't be like this.
