Sans' House Guests (CreepyPasta x Undertale)

Chapter 1 - Want A Sandwich?

It had hurt when Papyrus moved into his own house.

They were always the best of brothers. Of course, it was expected for him to move to his own house, to start his own life and pursue his career, but it still hurt. While he went to college, Sans sat alone in his house. He didn't like the empty house. Sans never did like being alone.

Sometimes he'd even call Papyrus and pretend it was a buttdial or a misclick just to talk to someone. He didn't mind his house, it was perfect for him. It was next to a forest, where he could go on long walks for thinking, and there was a hill with a perfect opening on the top to look at stars with his telescope. It was just the lack of people within his house that made him hate it.

Sans' career in science allowed him to easily pay for it. He didn't even get to see Alphys at his job, since she worked at a different lab. Sans was alright with some of his co-workers, but he couldn't find the will to try and increase his relationships with them. Each day was just like a useless loop of the last one. Wake up, get ready, go to work, come home, go to sleep, and repeat. Weekends he just sat around and watched T.V, sometimes doing chores he needed to do. None of his monster friends even came for visits, they were all busy themselves as well. Frisk was in school, Toriel was teaching, Papyrus was in college, Undyne was a chief of police, Alphys was working on a new robot prototype, and Asgore was working on political things.

No one even remembered Sans. He had recently found out, based on seeing his brothers facebook, that they had a family dinner where Toriel had invited everyone.

Everyone but him.

It hurt so much seeing that post. No one thought of even texting him? Emailing him? Sure, he had thrown himself into his work to distract himself from his impending loneliness, but they could have at least invited him!

Maybe that was the final straw that pushed Sans over the edge. He didn't care anymore. An explosion at the lab that placed a nasty crack on his ribcage? Eh, whatever, everyone gets hurt. He didn't bother telling anyone about it, and now there was a scar there. A few humans threw rocks at him for being a skeleton? He just stood there and watched, even taking a rock to the face and getting a bruise, once again not telling anyone. He wanted to believe good old Papyrus would still love him, he really wanted to, but he just having a harder time believing it.

And that's why, when he found a white hooded human standing in his kitchen with a knife and covered in blood, Sans just said three words.

"Want a sandwich?"

The hooded human was surprised, his lack of eye lidded pupils narrowing slightly. He seemed interesting, with pale white skin, covered in what looked like burn marks. His lips were cut into an eternal smile at the edges, the dried scars making even his frown look like a large, happy smile. He had thick, rangled back hair stained with dirt and probably dried blood, obviously having not been washed in some large time gap. His white hoodie was stained with dirt and blood, and so was the large knife in his hand and his black jeans as well.

Probably a murderer.

Whatever.

"What?"

His voice was raspy, loud and demanding. Quite the opposite of Sans's which was quiet, almost a little monotone, and just not sounding to care at all about his present situation. What was he going to do, kill him?

He's died before, he can die again. At least it'd be to a teenager, and Papyrus would still be alive.

"You're going to kill me anyway, might as well use up some of my food I bought," Sans said, pointing to the fridge, "I can make ya something. Like ham and cheese."
