Chapter One
Sans walked out from Grillby's after a nice dinner of ketchup. Just ketchup. He was about to teleport back to his house when he heard a faint noise. He stood still and listened intently. It had sounded like – there it is again. A meow. Sans walked around to the back of the restaurant to see a small kitten, shivering in the snow. Sans stared at the kitten for a few seconds, and it stared back. It meowed once.
A sigh came from Sans. "welp, i can't just leave you here. you'll die if I don't take you home right meow." He tucked the kitten into a pocket of his hoodie. "papyrus isn't going to like this," he muttered under his breath. "he doesn't even trust me to take care of the rock." He took a deep breath and teleported to his front door.
Sans was standing in front of the steps leading up to his house. He checked to make sure the kitten was still tucked into his pocket but saw a little face poking out. He gently nudged the kitten back into his pocket before opening the door. Sans was immediately greeted by the unique aroma of Papyrus's spaghetti.
"hey, papyrus," Sans said.
"AH, SANS, YOU'RE BACK," Papyrus responded. "I MADE SPAGHETTI."
"it looks great, papyrus."
"DO YOU WANT SOME?"
"nah, i'm full from grillby's."
"OKAY. I'LL SAVE SOME FOR YOU IN THE FRIDGE."
"thanks, bro."
Sans needed to wrap up this conversation quickly. He could feel the kitten crawling in his pocket.
"i'm kinda tired. i'm going to head up to my room, okay?"
"OKAY. GOODNIGHT, SANS."
"goodnight, papyrus."
Placing a hand over his pocket, Sans headed up the stairs to his room. He closed the door behind him and pulled the kitten out of his pocket. "hey, little buddy." The kitten purred. "i'll take care of you."
"but, uh, how exactly do i do that?"
A/N: Hello! This is my first Undertale fanfiction. Since this story mainly focuses on Sans, I'll be using a lot of puns. If you know any good puns relating to books (for next chapter) please share them in the comments! If I use them, I'll credit you for the puns at the end of the chapter. Thanks! ^-^
