Reader is one of Simon's only friends besides Janae. You bring up how excited you are now that it's nearing Christmas and Simon stays pessimistic as always.Credits to @theoats99 on Tumblr, inspired by their holiday Simon works, especially surrounding his mom's Holiday party!!

December 5th - Putting a mistletoe outside their door, then knocking. by kitkat_fic13
Fandoms: IT Crowd
05 Dec 2025
Tags
Summary
Prompt (Original): Putting a mistletoe outside their door, then knocking.
Bringing a mistletoe to the IT department and hanging it outside Richmond's door, then knocking. As we all know, Richmond isn't the most socially developed person, but he gets over his shyness and "freaky goth making out" ensues (direct quote from my planning ¬‿¬ )
Content warning: very brief mentions of sex/implied sex ;) probably the spiciest thing I've written
Yes, I'm aware that no one asked for this, it's a British comedy show from twenty years ago and Richmond is a minor character besides so yes, I know this is niche and no one needs this but I do so let me have my little goth baby, okay???

Prompt 54: winter power outage
There's a power outage in Hometown due to excess snowfall, which means a certain laptop's batteries are quite low. In the dark world, Queen is very tired and out of it because of her low battery and you help her to bed. And cuddle.
I feel like I add this to every fic but if this is ooc, I apologize, I haven't played Deltarune in a while.

Summary
Prompt 20: "Where on Earth did you get that sweater?"
You stop by Seb's house to visit him and he's wearing the ugliest Winter Star sweater you've ever seen in your life. Suggestive making out and partial undressing ensues.
His birthday is mentioned, Winter 10, and I know it's the 7th but pretend it's like the 16 of Winter today (specifically Tuesday).
I genuinely had no idea what I was going to write when I saw this prompt. Literally when I planned it, all I had was that Robin got Seb a really hilariously bad Christmas sweater. So I decided to make it freaky for absolutely no reason. ¬‿¬

Summary
Prompt 33: "Hey, cut it out. It's the holidays."
Sherlock is obsessing over a case as usual. You sort of take the place of Watson here, I guess. A doctor and roommate who sort of mothers/fathers/parents Sherlock (NOT IN A WEIRD WAY), like making sure he's eating and sleeping and taking care of himself.
In this fic, you've convinced Sherlock to take a brief hiatus from his case for the holidays, since it isn't incredibly vital or dangerous. Because it's only December 10th, this fic is set later in December. Think maybe the 20th to the 23rd?

December 13th - Tripping over a Christmas tree into their arms by kitkat_fic13
Fandoms: Hogwarts Legacy (Video Game)
14 Dec 2025
Tags
Summary
Original prompt: tripping over a Christmas tree into their arms
This prompt is original (didn't come from the tumblr post I've been using), but it was thought up by my friend, so creds to her, xx. At first, it was going to be reader falling into the character's arms, but when I settled on Ominis for the prompt, it was because I wanted to use him in promptcember and figured this fit his blindness pretty well <3Sebastian, Ominis, and you are all good friends, as well as Anne (and MC if you aren't the player), so of course you've been invited into the Undercroft. You and Sebastian are decorating the Undercroft for Christmas. Shockingly, Seb has gotten a tree there, and while he leaves to get more decorations, Ominis stops by to help out. Unfamiliar by the layout of the room now that it's decorated and distracted by the sound of your lovely voice, he doesn't remember to use his wand to navigate in time and stumbles over the tree, landing square against you.
Essentially, both the reader and Ominis are underage in this (15 y.o.), because I couldn't really think of a way to make this work with subjective ages. If that makes you uncomfortable, imagine it's a university Hogwarts AU, idk TvT

Summary
Prompt 2: cuddling by the fireplace
This fic is marked major character death because Death is literally what the story centers around. The reader is dead, and the Curator is literally Death personified.
The Curator is a super mysterious character and my personal favourite idea of his backstory and stuff is that he's Death himself. Beyond that, I've sort of gone overboard with his backstory so I'll put it in the notes. This particular fic is set during The Devil In Me story because that's the only one I've played. TvT
You and the Curator bid goodbye to the player before they begin the game and he seems slightly put out by the fact that he's unable to interfere. You comfort the touch-starved spirit with some cuddles. by the way I imagine that the Curator doesn't produce body heat as he used to now that he's Death but you do because you're still technically just a deceased soul and his companion. <3

December 15th - "Did everyone else come with a date?" by kitkat_fic13
Fandoms: Divergent Series - Veronica Roth, Divergent (Movies)
16 Dec 2025
Tags
Summary
Prompt 72: "Did everyone else come with a date?"
I struggled with the details of the plot so much TvT I really wanted the reader to be Amity but I also wanted Christina and Will to be part of it, so I'm making it not canon-adherering, sorry! I hope that isn't too horrible... Basically the only difference is that Christina goes to Amity at the beginning of Insurgent, and Will is alive. I know this ruins a big part of Tris' character development and her and Christina's relationship but it's only a oneshot anyway.
Imagine that when Tris and Tobias, Caleb, Christina, Will, and Peter hide out in Amity, it's Christmas, and they throw a holiday party among themselves to up the morale of the group. So Christina and Will are being all cute, Tris and Tobias are chatting, and Caleb is talking up some girl he met in Amity who's a Candor transfer. Reader is that girl's friend, from Erudite, and Tris is totally a fan of her, so you came along. Peter comes by, and asks said prompt question.

December 18th - Teaching them how to ice skate by kitkat_fic13
Fandoms: Until Dawn (Video Game)
18 Dec 2025
Tags
Summary
Original prompt: teaching them how to ice skate, created by @coconutbunni love ya <3
CW: mentioned suicide, depression, self harm, heavy themes, etc
CW: sex, but it's not explicit, non-descriptiveJosh is skilled in many sports (canonically, he's received awards in soccer, basketball, and American football, and talks about how he used to play baseball with his family), but skating isn't something he's ever considered, despite spending most of his childhood at the Washington's lodge on Blackwood Mountain. Luckily, there's a frozen lake nearby that you can teach him!
Reader's skating skills are mid-proficient, based off myself. I am by no means a talented skater (like hockey/figure skater level) but I can get around and my balance is good, so enough to teach someone who's never done it before. Reader is age 20ish, same as Josh. Gender neutral reader, with subjective undergarments (i.e. a bra if you wear one, non-specific underwear).
No prank AU, because that's too heartbreaking, but we're obviously keeping him with his usual baggage pre-prank. I'm also adding that he has attempted suicide before, such as after Hannah and Beth die, but for a more general reason than their deaths.

December 19th - "Wait, you're not going home for Christmas?"/"I'm not letting you spend Christmas alone." by kitkat_fic13
Fandoms: The Dark Pictures: The Devil in Me (Video Game)
20 Dec 2025
Tags
Summary
Prompt 35: "Wait, you're not going home for Christmas?"
Original prompt: "I'm not letting you spend Christmas alone."I'm using the same reader backstory as my other Charlie fic! The reader is a graphic designer/artist thingy at a big broadcasting company who's scheming with Charlie to get Lonnit Entertainment sponsored because their boss is a fan of Architects of Murder. In this fic, the broadcasting company has already sponsored Lonnit Entertainment, but there are still some tight Christmas deadlines. Implied that reader is younger than Charlie, gender-neutral!
I have another Charlie fic planned for Dec 24th/Christmas Eve, so I think it'll be a two-shot of sorts. Separate works that can be read individually and still make sense, but if you read them one right after the other, their plots will flow into one another. I'll add a link to the 24th one to this fic when it comes out!
The sequel is linked here.DISCLAIMER: These prompts are from a tumblr prompt list linked here.

December 20th - "Hey, want to get my parents off my ass for not having a date?" by kitkat_fic13

Summary
Prompt 73: "Hey, want to get my parents off my ass for not having a date?"
I saw this headcanon list for Andy that included the idea that his family is Jewish, linked here. Based on the one specific insult that Fletcher uses for Andrew which is religiously targeted. I myself am SBNR (spiritual but not religious) and celebrate a non-Christian Christmas. But I'm TERRIFIED of committing cultural appropriation, so the plot is vague. I'm using the idea that the Neiman's host a party around Christmastime but they don't celebrate it. The fic will be almost entirely focused on the reader and Andrew's relationship, not the details of the party.
Andy's cousins Dustin and Travis tend to bring their girlfriends to their party, and his family gets on his case about him not doing the same, so he asks along another player in studio band that he's starting to like, like.
