Sintember 2025 - Official Prompts

Due to the change in hands and time constraints, 8 of the 30 prompts have been chosen from the lists of previous years to be Legacy prompts, similar to Throwback Thursdays from last year. Next year, we will likely do only original prompts, but we do hope you enjoy our selection! Plain text and flavor text for all prompts is below the cut!

Lights, camera, action! - The spotlight can be its own prison, harder to escape than any other. But who doesn't want to be remembered forever? Chin up, baby! Let's make you a star!

Hunger - A fact of nature. Sometimes predatory, sometimes pleading. Leave it unfulfilled for too long, and you won't survive...

Mistake - Will the wrong choice be your last?

"Is that supposed to happen?" - The curiosity of a naïve victim, or the herald of a professional's bone-chilling error? Either way, I have a feeling I know the answer to their question.

Up close and personal - Nice and intimate. Too intimate, perhaps. Ever heard of personal space?

Not again - Legacy Saturday: You thought it was done, it was over. You survived, you moved on. And yet the horror continues.

"Why won't you stay dead?" - Legacy Sunday: It keeps coming back to this, again and again and again.

Prayer - Sometimes, it's the only thing a person can do. Especially if they'll be on their knees either way.

Masquerade - It could be the name of a fancy ball, but masks are useful for so much more. What lies behind them?

"Leave me alone." - Everybody needs their space.

Blood is thicker than water - And yet, it tastes much worse on your tongue.

Outcast - It's freeing to live outside society's rules, but loneliness is a poison. Careful to walk the tightrope.

The other side - Legacy Saturday: What lies in the mirror, another dimension, even after death?

"I love you" - Legacy Sunday: I do, I do, I do, I do, I do.

Amnesia - Those blank spaces where memories should be leave plenty of room for imagination to run wild.

Guilty pleasures - We all have to indulge ourselves from time to time.

Keep an eye out - Be watchful, be weary, use your sight to avoid the sight of others. Or perhaps you prefer a far more literal meaning.

Heart - It beats and it beats and it beats at its cage.

"Three's a crowd." - One person too many. Will they interrupt the moment, or embrace it?

The more, the merrier - Legacy Saturday: Group work can be fun, I swear.

Taboo - Legacy Sunday: Polite, civilised people don’t do these sorts of things. But some choose not to care.

No place like home - The longing for a time and place, strong enough to make you sick.

Nobody - My god, I'm so lonely, so I open the window to hear sounds of people— ahem. I mean: if you fall in a forest, do you make a sound?

"Till death do us part." - Only one thing can separate us. Between my presence and everything's absence, what will you choose?

Collared and leashed - Heel. Sit. Beg. Roll over. Good pet.

Immaturity - Is it true innocence, or just the illusion of it?

Philia - Legacy Saturday: Got a kink or a paraphilia? Is there never enough content for it? You know what to do.

Disgust - Legacy Sunday: Things that slither and ooze, the constant decay of the earth beneath your feet. The things that make us sick, so we turn our heads and do our best to forget.

False hope - What a unique form of torture, to always be reaching towards something that isn't there, chasing the shadows on the cave walls.

True Freedom - Exactly what it says on the box. Careful how you use it.

Prompt: (day 17 - Keep an Eye Out)

She’s here. You’re sure of it. You can’t prove it, but every cell of your body is saying she’s here. Cautious eyes scan the food court. Lots of people here. None of them are her. You check your escape route. Still open. Your spine tells you it’s time to move all the same. Blending in HAS worked so far, but she’s certain to find you if you don’t change positions. You rise from your chair, pushing it back in (not even the fear of what’s coming will stop you from being decent)

A quick step. Darting looks. Checking corners, any shadow could hide her. You’re almost to your second spot. A quick check of your watch. 12:45. Almost done. 15 more minutes of avoidance. A cursory check behind you. There she is. Gray hoodie, leggings as pants, comfortable black sneakers. Losing her should be simple at this distance. You round nearest corner to the bathrooms. Speeding up slightly. You can lose her in the back hallways, stretch out the time. Even if she catches up, you’ll be safe after 1:00. As you disappear from public view, you take off running. Taking the first left, you crash into someone. Worst case scenario. As you scramble to your feet, you look back. How close is she?

She’s…not. Nobody is there. Did you have the wrong person? As your unfortunate victim gets back to their feet, you turn to apologize only to be slammed face-first against the unflinching plaster.

“Got you~!” Ice floods your veins at the familiar voice.

“Wait, please, don’t-“ You start. You always beg. You really shouldn’t. It just makes it worse. Her cock digs into your ass as she takes a deep whiff of your scent.

“You really worked up a sweat for me today. Good girl~”

Greetings, I am interested in joining Sintember. Whenever I write stories currently, it's filth porn for myself. I will probably not be doing that for Sintember. Point is, I don't really post any of my more taboo writings online. Do you perhaps know what kind of stuff I can get away with posting on Tumblr, and which kind of stuff I'd need to post elsewhere, and if so where? Thanks in advance.

Hello!

We're delighted to hear your interest in joining our indulgence!

Tumblr as a site tends to have alot more issue with images then written content, and from experience you are highly unlikely to have any issues with content as long as it's not mass reported. So possibly consider the risk of maintagging a work, if you are writing for a particularly hostile fandom.

For sites elsewhere, if it is fanfiction which you are seeking to contribute, then A03 is the perfect site. We even have a collection there, where you can find all sintember stories, from all years! As for original fiction, that one's a bit more complicated. You may either create a Wordpress account, or your own site to host it, as to best avoid censorship from parent companies, or harassment from fellow site-users.

Hope this was helpful, we are eager to see your contributions!

Sintember 2024 - Official Prompts

Throwback Thursday prompts have been decided, so here is the official list of prompts for this year! Plain text and flavour texts for each prompt are below the cut.

Innocence - What would you do to preserve it, what will be done to tarnish it?

You just let it happen - Bystander, victim or accomplice, perhaps you shouldn't have let it pass...

Fame - Intoxicating in its power, mesmerising in its influence.

Can't let go - Everything you've tried to, has claw marks in it.

Throwback Thursday #1: Coercion - Subtle application of threat, the brute force of physicality, or could it be someone’s will itself working into their brain?

I love you - I do I do I do I do I do.

Forgotten - And time moves on.

"You are beneath me." - How does the boot taste?

Horrifying concept, thank you - A small change in the world could be a nightmare.

Replaced - You aren't what you were. To yourself, to them.

Self-care - Why feel guilty for a little treat?

Throwback Thursday #2: Captivity - How long has it been? Does the sound of your captor getting closer bring fear or hope. Has it been long enough to become joy?

"Why won't you stay dead?!" - It keeps coming back to this, again and again and again.

"It wasn't me!!" - But why would they believe you?

Learning - Maybe some things are better left unknown

On Display - Like a product on a shelf, no hiding from the eyes.

Pick a Side - You're torn, of course you are, but the time has come where the only other option is to lose both.

"You came back?" - But is it too late? What's done is done.

Throwback Thursday #3: You weren't supposed to enjoy that... - Are they judging you? Really??

Well, well, if it isn't the consequences of my own actions... - How inconvenient and unexpected and harrowing for you.

Tragic Backstory - We all know you've done horrible things to your OCs that you haven't put anywhere else. ;)

Ownership - Mine.

It's just business - No need to get all personal about it.

Revenge - A dish best served however the hell you want.

Magnum Opus - One's greatest work, one that will go down in history.

Throwback Thursday #4: Obsession - Love? Hate? Lust? Fear? Worship? Whatever the case, it’s all they can think about.

Too good to be true - And thus...

Cultivation - What does it take to make this grow, for a good harvest?

BDSM done wrong - Self-explanatory, really. :3

True Freedom - As always, write whatever you like~

The Object Of Desire - Chapter One (A Fresh Face)

Summary: Someone new arrives at St. Mathilde's just as things calm down after the enigmatic Fiamma's departure. (AU where Fiamma returns to Spain before Miss G can take things too far.)

Word Count: 1,130

Warnings: Obsession, hints of future minor/adult relationship

A/N: Miss G will be referred to as Camille, as she was never addressed by a first name in the film.

Following Fiamma, Camille did not think she’d ever feel desire again. No one and nothing could ignite her passion as the strangely exotic girl once had. It broke something within her when Fiamma left. She’d never even gotten close to the girl, though no matter if she had, nothing would have been close enough for Camille's liking.

She performed her duties as she must, but lacking any of her usual luster and flair. She taught her girls their lessons and supervised her once treasured diving team, but her day to day always felt hollowed out; empty. She was positively devoid of feeling, and some days she wished only to scream. At least the rawness of her throat afterwards would be a feeling of some sort. Yet she resisted the urge.

It was torturous for Camille to not have something, or rather someone, to focus her thoughts. Someone to impress, charm, woo, that’s what she needed. She could regale the girls with tale after tale, both real and made up, but she never wanted attention from the masses. No, Camille wants singular devotion, one person to be sucked in by her as she is by her desire for them. And that was what was missing.

One morning, after suffering a particularly dull and dreary week prior, Camille woke up to a shift in the air. She wasn’t renewed with hope, but more of a cautious optimism. And it turns out she had a right to be optimistic. A new arrival was to brighten her day exponentially. It was at mealtime when she first crossed paths with the newest student at St. Mathilde's.

Aerla Grae came from Ireland. A recent incident that was not entirely divulged to Camille, had resulted in fifteen-year-old Aerla's transfer to the school. Camille was advised to keep a close eye on her. Following her colleague's gaze, Camille's own eyes first landed on Aerla, and she decided in that moment alone, that keeping watch of her was not going to be a problem.

Aerla sat alone at the end of one of the tables, keeping her distance from the other girls. Camille watched as she tucked her mass of red curls behind her ear in order to eat. Camille drew a deep, silent breath as she became transfixed by Aerla's every small movement.

It was apparent to her that she was nothing like Fiamma, not in looks, nor, Camille suspected, in personality, as Fiamma had been such a social creature, where it appeared Aerla had a much more individual nature. Aerla had also arrived here from another country, but that's where her similarity to Fiamma ended. Yet, all the same, Camille was utterly enchanted.

Spotting an open seat across the table from Aerla, Camille left her colleagues in favor of making the acquaintance of the newest member of their little school. As she slid into the vacancy, she caught the girl's attention. Aerla paused, fork halfway to her mouth, as the soft breeze from this stranger's arrival ghosted over her face. She sat down the bite of food and tilted her head, regarding the woman with curiosity.

"Miss Gribben," Camille introduced, offering her hand to Aerla from across the table. She briefly considered giving the girl her first name, but thought it best to stick to a more formal approach for now. Camille's heart leaped to her throat when Aerla took her hand to give it an awkward shake.

"Name's Aerla Grae, Miss," Aerla replied politely, though there was an edge to her voice that seemed to Camille as if the girl would rather have not been disturbed. At that, Camille should have left, but she couldn’t bring herself to do so. Instead, she stayed, remaining quiet so as not to disturb her further. Some of the other girls at the table cast suspicious glances down their way, but one glare from Camille and they went about their own business once more.

They were isolated at their end of the table, just as Camille wanted it to be. There was a danger in numbers. It had been that way with Fiamma. She vowed then that it would be different with Aerla. She wouldn’t let anyone come between them. Despite her efforts not to stare, Camille's eyes wandered back to Aerla time after time. She wanted to ask questions, get to know her, but the girl's standoffish tone gave her pause. She couldn’t push, or she’d resist, just as Fiamma had.

Camille attempted to push the thoughts of Fiamma out of her head. That was the past. She only need think of her in order to not repeat her past mistakes. It would only serve to depress and anger her to think of the wretched girl now. Now she had Aerla to think of. Aerla deserved her at her best, not sullen and moody. And she would prove herself in time. She just had to figure Aerla out and be what she needed her to be.

A thought nagged at the back of Camille's mind. In spite of herself, she voiced it. "Tell me, what exactly was it that brought you to St. Mathilde’s?"

Aerla seemed surprised by the question, as she froze, eyes widened. After she swallowed her bite of food, she answered with another question. "What have you been told?" She sounded accusatory, as if Camille already knew the truth of her situation and still wanted to hear the confession from her own lips.

"Only that there was an incident that resulted in you leaving your previous school for this one," Camille informed gently. Aerla seemed quick to anger, and that was the last thing Camille wanted to leave as a first impression.

"It was harmless," Aerla began in defense of herself, leaning in so as her story would reach Camille's ears only. "I kissed one of the girls at my last school." Camille's heart pounded in her chest at Aerla's admission. It began thudding so loudly in her ears that she feared she wouldn’t be able to hear the rest of Aerla's story. "We got caught in the stairway and the stupid girl blamed me. Said I'd taken advantage of her, when she wanted me to do it, but was too ashamed to admit to it. So I was expelled and sent here. I’m surprised they didn’t tell you. They had no problem telling everyone else as if I’m some sort of monster."

"You're not a monster," Camille was quick to reply. "You followed your heart, your desire, and that is the most important thing in life." This elicited a smile from Aerla, as Camille suspected she may have been the first one to stand up for her and take her side in this matter. Perhaps this would be her way into Aerla's heart.
