Undertale Oneshots

How did it turn out this way?(Yandere!Sansxreader)

Pika: hehehehehe this is my own idea that I've been wanting to write for a while now. Then @xCoolSkeleton95x requested! Glad I'm not the only one that wanted this...

Sans: *looks at pairing and somehow pales* oh no...

Pika: *nods* yep Sansy you're a yandere in this!

Sans: I'm out. *teleports away*

Pika: Kinda don't blame chu. Enjoy everyone!

Sans watched you as you traveled through the underground. He watched as you battled Asgore only for Flowey to come in at the end and ruin it. He watched as you went through it all again just to save them all this time. You had become his obsession. You were what he wanted and he was going to have you, WHETHER YOU WANTED HIM OR NOT.

You were at Alphys' house, watching anime. You had finally gotten them all to the surface a month ago. You lived with the Skelebros back in Snowdin cause they haven't built a house yet. Toriel had wanted you to stay with her but Sans had insisted that you stay with them for some reason.

"So I can keep a good eye socket on you kid." He had told you but you didn't really believe that was the case. Still you ended up staying and until their house was built, you slept on the couch. Sans had offered you his room but you declined, he also offered to sleep with you, which had made you blush and decline it as well.

Checking the time, you noticed that you needed to go soon to meet Sans at the entrance/exit of the underground. Alphys had already moved up cause she was the royal scientist.

"Alphys I gotta go. See you later okay?" You told her and she nodded as you left.

"Hey." A voice said as you walked out the door. You squealed slightly and turned to see Sans leaning against the wall, grinning mischievously at you.

"Damn it Sans you scared the hell out of me. I was going to go meet up with you you know. You didn't have to come all this way for me." You told him and he only grinned before grabbing your hand.

"Well didn't want to make you walk. Come on, I wanted to talk to you anyways." He said and you nodded as the two of you walked. Sans never let go of your hand and it personally made you blush.

"Okay. Better hurry though, Papy will get mad if we're not back in time for spaghetti." You said playfully and he nodded and gave you a forced grin. That made you worry. Usually if Papyrus was mentioned he was happy but when you said his nickname, Sans practically hardened. It was weird.

"Yeah... Here I know a short cut..." He to you and suddenly you were in a small clearing.

"Okay. So what do you want to talk to me about Sans?" You asked and he smiled at you before blushing slightly.

"I umm. Wanted to ask if maybe... I really like you more than a friend and wanted to know if you would go out with this lazybones? What do you say (Y/N)?" The words rushed from his mouth and you gasped slightly in surprise before blushing.

"Um. Sorry Sans, don't feel the same way. We can still be friends though right?" You ask and Sans frowns slightly before smiling again and nodding.

"Sure. Guess I went a bit too over my skull, trying to ask out a hottie like you." He commented and you blushed.

"I'm not a hottie but thanks for the compliment. Can we go home now?" You ask and he nods before teleporting you back.

Sans wasn't going to give up easily though. You were HIS.

_Time Skip_

It's been a year since you've rejected Sans. It got really awkward afterwards and you ended up moving out and into your own house. Papyrus had understood, knowing what had happened, but Sans refused to talk to you after you did. You knew it was because you rejected him but it still hurt to know you lost a friend because of it.

Today you were going to visit Toriel. She had invited you over along with the Skelebros in an attempt to get Sans to talk to you again. Even Papyrus had stopped talking to you because of his brother.

You arrived at her house and knocked on the door. For a moment, there was no response, until Sans opened the door and smiled at you.

"Hey (Y/N). Sorry, Tori and Paps went somewhere to get something and so you're stuck with me." Sans said and you nodded and hugged him tightly, surprising the Skelton.

"I missed you Sans. I miss hanging out with you." You told him and he hugged back tightly and buried his skull into your hair.

"It's fine. Come on, let's get inside before we're chilled to the bone." He joked and you giggled and nodded. Sans closed the door and, without you noticing, locked it shut.

He had already gotten rid of Toriel and Papyrus. They were in his way of you. Sure he'll miss his bro but with you, he'll live. YOU WERE HIS NOW AND YOU WEREN'T LEAVING HIM EVER AGAIN.
