[Undertale] Sans X Reader - Repeat, Eternally

Chapter 27 ~ Underfell Sans, of Hunting You

WARNING: EXTREME VIOLENCE AHEAD. LIKE, SERIOUSLY EXTREME. I DON'T EVEN THINK THIS IS CHILD-APPROPRIATE ANYMORE. 

lol it's not even appropriate for children in the first place

Shut up, Sans. I added music. xD

lol

Wood flew everywhere and a skeletal hand burst through the door. It began to feel for a doorknob, and you remembered not to panic. You closed the garage door and dove for the dining room, sliding under the table. 

Moments later, you watched as slippers came in. You couldn't see his head, only up to where he kept his hands in his pockets.

"Hellllllllllllllooooo...?" Quiet, psychotic laughter. "Hey, kiddo. Where aaaaaaaaaaare yoouuuu?" 

The click-clack of his bones sent shivers down your spine. He began to walk forwards. He reached for the garage door's handle and-

Crash.

You knocked over a chair. His body whipped around so fast that it almost seemed impossible for Sans. He began to stride over to the table, lifting a foot off the floor. 

The table flew into the wall, revealing you. 

"There you are, kiddo. Was worried I lost ya, there." 

You took a mad scramble, but his foot hit your side, and you keeled over, coughing uncontrollably. His skeletal fingers wrapped around your neck, and you began to choke.

"We're gonna have lots of fun, baby."

You kneed him, right in his pelvic bone, and he doubled over. You weren't without injury, either. You got up, limping for the living room, and painfully flipped yourself over the couch. Underfell Sans followed, and snarled, grabbing onto the couch and literally throwing it into the wall. It burst through. You wouldn't be able to escape that way anymore without major negatives, as it blocked the main hallway. There was only one place to go, and that would be upstairs. Sans was gaining, despite being in immense pain. Skeletons may not have organs, but if you decided to strike certain parts of bone, even they'd be stopped temporarily. 

You were finally on your feet, and you rushed to the stairs. You felt the heat of the laser of a Gaster blaster on your back. It had missed you by 3 centimeters, but a gaping hole remained in the wall to the outside.

"You're making me angry. You don't want to upset me, now, do you? Just give up. Do it now! Let go of your DETERMINATION!" Sans protested.

But it refused.

You sprinted up the stairs, slamming into the dresser at the top. It hurt, but you had to keep going! You had to! You dodged to the side, just in time to avoid another blast.

You ran into a room, and locked the door. You backed up, and you felt the feeling of bone on flesh.

"Where are you going?" 

Underfell Papyrus clutched your arms, and lifted you into the air. It felt like he was trying to tear them off. You were kicking, and started to scream.

Sans walked into the room, having picked the lock. He grinned.

"Now, now. Look at this little kiddo. Struggling. Cute." He chuckled, between breaths. "However, what ya did was really, really stupid. So now, you're gonna apologize." 

Sans dug his fingerbones into your chest, right below. He pressed harder and harder until he broke the flesh, and blood began to run down his fingers. It was painful as hell.

"I'm sorry!" You screamed, at the top of your lungs.

"I...can't....hear...you...~" He began to dig his bones deeper into the already-made wounds.

"I'm so sorry! I'm sorry!"

"Who are you sorry to?"

"Y....you!"

"What was that? That wasn't a full sentence. Don't you wanna get good grades?"

"I'm so sorry, Sans!"

"For what?"

"I'm sorry for running away, Sans!"

He withdrew his fingers, which were covered in blood. His eye was already red.

[I'm sorry I'm using the ectoplasm tongues]

A red tongue stretched from his mouth, leaving you in complete terror. He quickly licked all of your blood off of his fingers.

"We're gonna have a lot of fun together from now on, kiddo."

DONE DONE DONE DONE ALL THE DONE RIGHT NOW

I WARNED YOU!

VIOLENCE!
