THIS POST IS NOW CLOSED TO NEW PROMPTS.
New prompts can be posted to Post 2.
Fills may continue to be posted to this post at any time.

How-To's, Rules and Notes Behind the Cut
Prompts should be one prompt per comment, formatted in this way: fandom, character(s), prompt word/sentence
Prompts may also be open ended, unspecific, or anthropomorphic, such as:
or
Earth geography, sand, I don't like humans very much, either
Prompts for relationships are welcome; a / is used for romantic/sexual relationships and an & for platonic. A prompt that uses both means the relationship can be written as either romantic or platonic, such as:
Prompts may be repeated if they are unfilled; there is no obligation to read through every prompt to make sure yours isn't a repeat. This year's 3SF will stay open for new prompts through Sunday, February 15th.
Respond to your chosen prompt with a short fic of three sentences containing the fandom & characters requested!
Prompts can be filled more than once, as many times as someone has a new idea for them.
No, fills do not need to be exactly three sentences! It's more of a guideline. Please abuse grammar and punctuation as much as desired.
3SF is a Choose Not to Warn space. Spoiler and content warnings are not required, though writers are free to add them if they please. If you see something you don't like, just scroll until you do!
A Dreamwidth account is not needed to participate. Anonymous prompts/fills are welcome, or you can use Open ID. Using an account does make it easier to see people's responses to your fills though!
Cross-posting is encouraged; there is a 3SF Collection on AO3 if you'd like to post fills there as well.
Note that the comm is searchable if you're logged in! Tick the 'include comments' button when searching to easily find prompts for your chosen fandom/characters.
And most importantly, have fun! If you have questions, check the Sticky Info post and if they're not answered there, head to the Contact the Mods post.
Please remember to check through the rules and info and then go absolutely wild.

Date: 2026-01-17 09:03 pm (UTC)They're keeping up with the times, exploring and learning and enjoying, because living forever hasn't gotten old yet (but it might, if they stop) — and so it is they miss the obituary in the Sun-Times, not front-page, but arts and culture, about the city's very own blues legend, his life and times.
It takes a while for the news to reach them, though they wind back to Chicago when it does, go and sit at the bar, listening and not drinking, taking it in: the last one who was there, who knew them from before — the last tie to home, what they're really mourning, all those losses that came before.

Date: 2026-01-17 07:00 pm (UTC)Kissing her felt like stealing a piece of herself back she'd lost years ago; after all, running around being studious, patient, or virginal hadn't stopped The Lion from barring her from heaven. If he meant to keep her out, then she'd just have to settle for whatever Eden she could cobble together on her own, bruised hearts included.

Date: 2026-01-18 04:51 pm (UTC)The breath in his lungs left him in one forceful exhale, replaced by briny water with his reflexive inhale, ready to cry out, ‘If only I never met you, Cassian Andor—if only.’
Instead, he broke the surface of the water, coughing and purging, and the sun shone down on him—on Kino Loy, a man who had so desperately followed the rules, rules made to keep him cowed and in the dark—and he smiled.
One way out.

"This is our child in here," he murmurs as he takes his hand from her hair to press against her stomach and his eyes are so dark with want and the wine even as he drives deeper into her.
"This," she pants and she doesn't have the excuse of drink addled brains to lend her a blush, "and how ever many more you can give me."

Date: 2026-01-18 04:01 am (UTC)A loud BANG and the sound of Phainon hollering, "I got him! I got him square in the kisser!" nearly sent her rocketing into the sky above the Eternal Page, and what happened next did make her jump.
Mydei's growling voice rang out next. "Watch this," he said, and with the most dreadful bang and smash, another one of Lygus's torsos flew through the air, landed next to her, and skidded for a distance before stopping. The head was attached to this one, though it fell off upon landing, and there was a brick sticking out of it.
This one might make a nice birdhouse, she mused.

Good children don't fuck their siblings, so one has to wonder, if they could be so pleased to take one of their siblings to bed, why not another?
But there is also another truth, deeper and more hidden than even the last--it doesn't matter if any other person they took into their beds shared their blood or not. What they have is written in agony, in love, and a need so great that no one else could fill the voids in themselves but each other.

"They'd already closed your eyes," she says at the graveyard, when everyone is gone, "I never got to see them again."

Rune probably would have liked to kill him — yes, with that bloodhound curiosity ways of hers, she seems the type; you seem the type; but if you were to reach straight through your chest, nothing comes out... you are not Rune, and certainly not deserving of deciding this, you and your stupid heart.
"—I'm sorry," you say to swallow his penance, brushing a ghost of a kiss on his damp forehead, "but if I hated you forever with my empty heart, there would be no difference."

**2- Both the additional and the desired pair of wings will resist all dispelment until a subsequent full moon with identical weather conditions can be harnessed.
