A Certain Obsession- Undertale Sans X Reader

"Human?"

It's dark. You hear The TV and you suddenly open your eyes. You wake up to see you're lying on the couch with a blanket on top of you. You must of fell asleep. "Hey Kid, You fell asleep pretty early last night. You alright?" Sans was wearing a blue sweater and his usual shorts. He leaned against the wall eating leftover spaghetti. You wondered.... 'Spaghetti for breakefest?'

"Sans, Why are you eating Spaghetti for breakfest?" You asked. "This isn't my breakfest. It's my lunch, it's 12:30." (PM) HE replied. Your transformation must have taken a lot of energy out of you. You also felt that your clothes were pretty tight, you were surprised they fit you at all. You started thinking about asking Toriel for a new sweater but suddenly the door crashed open. "HELLO, HUMAN! I AM BAC--" Papyrus stopped mid sentence once he saw that you looked older. "Uh.....HUMAN?" He questioned. Wondering who you were. "Papyrus, it's me, Frisk." You spoke.

*Time skip, You explained to papyrus what happend, time skip brought to you by Arbys, we have the meats! (HEY)

"SO. THIS Means you are not a child anymore?" "Yep. I'm pretty much a teenager now." You said giggling a bit. You thought it was funny, but papyrus looked pretty serious. You afraid of what he was going to say. But then the tension was cut and he Yelled out. "HUMAN! YOU LOOK SO PRETTY!" He then ran up to you and even though you were bigger, he still picked you up easily. "I SHALL SHARE THE NEWS!!!!!!" Papyrus ran straight for the door, kicked it open, and ran off to spread the word. "Heh heh, Papyrus, Papyrus." Sans said with a long sigh. He looked tired. This made you worried.

So you asked "Are you okay, Sans?" He looked at you with a sleepy expression, but then snapped out of it. "Eh! Y-Yeah, Kiddo. Everything's fine! I'm fine!" 'Did he even get any sleep?' You thought. Then suddenly someone else blasted through the door. Sans spoke "Oh no, not Undy--"

"HEY HUMAN!" Undyne ran up to you, shaking the household with each step, then she picks you up. She looked angry, but then changed her expression from angry to happy. "WOW! Look at you! Who said you could grow up so fast?!" She howled and put you down. You shrugged. "Finally! Another girl who's almost as tall as me! This is AWESOME!" You laughed on the inside. Then Undyne Grabbed Sans and squished you and him together. "I CAN FINALLY SHIP YOU TOO! THIS IS SO GONNA BE MY NEW OTP!"

*You look over to Sans who's face is covered with Blue. You blush as well.

You didn't know what to think, but what you did know was. Being with Sans wouldn't be so bad.......You, actually kind of liked him back.
