Grillby X Sans ~The date

FLUFF

Don't hate me if you don't like it X3 I've started to ship it recently. I mean, I ship almost everyone but this is my favorite right now. What's your favorite?

"So Sans..." Frisk started, a mischievous smirk spread across her face like wildfire. 

Sans opened an eye and glanced at her. "Yeah kiddo?" 

The two had been hanging out at the skelebro's house while Frisk waited for Papyrus to get back from his cooking lesson. It usually takes him a while, especially since they started to cook more than just spaghetti. And since Frisk and Paps are best friends, she's always waiting for him, and Sans can't leave her alone all the time. 

"When are you going to tell him?" She giggled a bit as a look of total confusion washed over his face. "You know, the 'bright and hot gentleman'?" 

The small skeleton's face flushed a bright cyan, but he just closed his eyes and struggled to keep his composure. "Excuse me? I have no idea what you're talking about." 

Sans crumpled the note in his pocket and tried to think why Frisk was asking this. He had literally never told her anything about him. It couldn't be a reset, the look on her face gave nothing away that hinted towards it. Yet, she quoted him perfectly... 

"Oh come on, silly!" She giggled again in an innocent way, "You two are a perfect 'match'!" She laughed and leaned on his shoulder for balance. 

"Nice one, kiddo. Heh, but I'm not sure about that though."  He chuckled awkwardly and shoved his hands deeper into his pockets. 

Frisk glared at him and walked towards the front door. She looked back at him and grinned. This was not normal behavior for the small human. Sans rushed outside to catch up with her to see what she was up to. The snow around him seemed clear of human footprints and Frisk was no where to be seen. 

Blue illuminated through Sans's white t-shirt as he began to panic. Nothing like this has ever happened in the other timelines. Then again, Frisk has usually freed everyone by now too. Everything was begging to actually be new, not repetitive. Sometimes... That scared Sans. 

"Frisk what are you up to?" Sans growled and looked around. 

"If you're not going to tell him then I will. He's already waiting for you anyway. He told me to tell you." Her voice came from above the skeleton. 

Sans blushed when he realized he had been using his magic to hold her up. His nerves had gotten the best of him. It didn't happen often, but one time he had held Papyrus in his own room while he told puns to his brother. He didn't know why he wasn't leaving like normal, but then realized his magic had acted up. It took almost a week to calm his brother down.

"Wh-what does he need me for?" Sans asked the human suspiciously as he gently let her down. 

She just winked and ran off towards his restaurant. Sans growled. He wasn't having any of that. Quickly, he dashed behind a tree and teleported behind a tree next to the building, trying to stop her from doing anything irrational. He walked around and looked for Frisk. She wasn't running toward the building anymore, instead she wiggled her eyebrows and walked inside 'Librarby'. 

Sans cursed silently to himself, then pushed the door to Grillby's open. Just like normal, except... He couldn't wipe the warm blush off his face. Sans leaned against the door and tried to calm himself. Yes, he had a crush on the monster, but it seemed impossible for it to actually work out. The fire monster seemed to be out of the skeleton's league. Grillby was always so nice and respectful, and Sans felt like trash. Sometimes it would seem like Grilbs was flirting but Sans had to remind himself that he was blowing things out of proportion.
