Broken on the Inside. UnderLust Sans X Reader Fanfiction.

You were wrong.

Your POV.

Your eyes were wide. He must have mistaken you because your were flat out terrified. He pinned you against the bar and then teleported to his room.

"How about we have some fun~" You didn't know what you were doing, you just knew you needed to act...

And you slapped him...

He backed up immediately and held his face. You were horrified with your own actions. He just stared at you as his eyes faded to black.

"I-I didn't mean t-to! I-I swear." All you could see were his empty eye sockets, filled with guilt and betrayal. He teleported you to the back of Grillby's in the alley.

You sit down against the wall and start to cry. Someone approaches and nudges you with their foot.

"Leave me alone." They didn't react to your comment and nudged you again. You looked up into the eyes of a monster that grabbed you by the chin and pulls you up before pinning you to the wall.

"Hey, I got an idea. How about to and me have some fun~" you punched him so hard his jaw dislocated.

You ran to your house, not caring what people said, and cried into your bed. You cried yourself to sleep and woke up to the sun.

It's been a few months...

You haven't seen Sans anywhere...

Not even Grillby's...

You're scared of what happened to him. His brother doesn't seem to be acting normal. Papyrus won't talk to you. And everything starts going downhill from there.

Your parents die. You lose your job at the store. A few people have tried to kill you for no reason. And you find yourself crying outside the back of the store.

Someone walks up to you and stops as if they recognize you, and sits next to you.

It's the last person you expect them to be...
