Gyft-Christmas Troubles

Fandom: Undertale
Rating: T
Warnings: Allergic reaction, hospitalization, attempted murder
For Fictober Day #1
Sans felt like a loser of a stepfather, okay truthfully he had no idea if he was even considered a father to Frisk. Toriel is their adopted mother, and he married her later on. So he guessed he was just Frisk’s guardian in a sense. 
He wanted to show an effort to Frisk, especially after they confided in him that they only stayed with Toriel because they had nowhere else to go. They expressed anger and disappointment at the monsters trying to kill them then expecting forgiveness. 
This is probably why his gift of matching sweaters was a bad idea. Wasn’t it a human tradition to wear uncomfortable, ugly, matching sweaters for Gyft, sorry Christmas? Apparently that wasn’t a thing.
When Frisk put on theirs, they started scratching and breaking out in hives. Toriel had to escort them to the emergency room. Sans was waiting for a call, after Toriel texted him that Frisk is apparently allergic to cotton. How was he supposed to know that? Cotton isn’t exactly a common allergy. 
What kind of father is he? He ruined Frisk’s first Christmas with the family. Or is it their first Gyftmas, he didn’t know. 
Papyrus came into the living room after he finished Toriel’s pie. “Brother, why are you down? We’ll continue the party when Frisk is back.”
“I ruined their Gyftmas. Who wants to spend the holiday in the emergency room?” Sans sighed, “By giving them a present.” 
“Give them a better present?”
“How? All the stores are closed.”
“Make one. I know Frisk likes your puns for whatever reason. You are no stranger to crowds either. Give them a show they enjoy.”
“I got to set it up.” Sans was being pulled off the couch, “Oof Papyrus, it’s a little late to do it now.”
“Nonsense brother.” Papyrus stamped his feet, “It’s not too late, let’s go.” 
This is how Sans ended up in Sans room. “You can sow. Let’s start with ribbons.”
Papyrus and Sans finished the ribbons they were sowing together, pink, green, yellow, and red. Sans made the red ribbons look like they were glowing, apparently humans had a reindeer whose nose glows. It sounded kind of silly, but who was he to argue about someone’s looks. Plus, he didn’t want to get on the bad side of any reindeer. 
Frisk did help him make treats to appease the reindeer. It was mostly chocolate? So maybe he could give Frisk some after the performance. He did put soda in their stocking, but they looked disgusted at the sight. He really should have gotten to know Frisk better, especially since Undyne took him aside and told him that they knew Frisk hated soda. 
While contemplating his failures as a guardian Sans hung up the ribbons around the living room. Papyrus put flashlights on the coffee table beside the couch. 
When Frisk came home guided by Toriel to the couch, she called their friends. When everyone arrived Toriel warned the group, “Frisk is a tad loopy. Absolutely no roughhousing. They are to sit and relax.” 
Sans got Frisk’s attention, “Sorry about the emergency room, kiddo. I got you another present while you were gone.” Frisk looked happy enough. 
Sans got up front while Papyrus turned the lights off before directing people to shine their flashlights on Sans. When Sans had the light on him, he started cracking jokes and some bad puns to Frisk’s amusement and Papyrus’ reluctant acceptance. 
Afterwards Sans got something he wasn't expecting, a hug from Frisk, for the first time ever. “Best Christmas ever.” Well that settled it, this holiday was now Christmas. 
Sans hugged them back. “I’m glad kiddo.”
