Undertale AU Sibling Oneshots

Undertale! Bros x GN! Reader

(only reason GN is specified in the title is because it was specified in the request! Otherwise no pronouns in title is still GN)
(I figured Frisk is a bit older, around your age in this one)

Requested by the lovely Missi_Ana_Jones!~

You walked inside after spending most of the day with Frisk. You shedded your boots by the door, walking into the living room only to stop upon seeing Sans' stupid grin.
"What."
"You've been spending a lotta time with Frisk lately, haven't ya?"
"What?"
Sans laughed, smiling warmly at you. "You two suit each other."
"S-Shut up, Sans." You huffed, cheeks dusting in a blush as you attempted to pull your beanie down to hide in it.
"I'm justing teasing you a bit, (Y/n)."
"Dinners ready you two!" Papyrus called from the kitchen, "How was your time with Frisk, (Y/n)?"
You stuck your tongue out at Sans' stupid grinning face, turning to head into the kitchen. "It was good, Pap!"

You walked alongside Frisk, you both headed to the carnival that was in town. Frisk was chatting away about some ride that made you want to throw up your non-existent guts.
You had to distract them before you lost your appetite.
"Hey Frisk, do you think they've got those funnel cakes you keep talking about?"
Frisk gasped, grinning ear to ear. "Oh I hope so! They're sooooo good!"
Frisk, upon hearing word of the carnival, hadn't shut up at all about the rides or the funnel cake. Since you'd never been on the surface before, you'd never heard of a funnel cake.
"So what exactly is it?"
"I'm pretty sure they take waffle mix, fry it, and then cover it in powdered sugar!"
Drooling.
You were drooling.
Frisk laughed and took your hand, dragging you deeper into the fair. You both found the funnel cakes soon enough, and the cotton candy.(*cries in my hometown fair hasn't been here in two years due to pandemic* I want funnel cakeeeeee)
You both ran around, trying out rides and games, trying out more rides after you met up with your friends, and when the sun began to set you both headed home to watch a movie.

You awoke the next morning both tangled in the blankets and Frisk's limps. You thought about moving.
Key word is thought.
