Q: When will the prompts be posted? A: Prompts will be posted weekly on Wednesdays around 10am EST/New York timezone.

Q: Where are prompts listed? A: They will be posted here on Tumblr with the tag #microcest prompt, there is a text-only list of prompts on Dreamwidth as well.

you can also view them on our Microcest Calendar or Microcest Prompt Gallery

Q: The day for the prompt has already passed. Can I still write a microfic? A: YES! You can still submit a microfic for any prompt that has passed, just note the original prompt date in your submission.

Q: Will you reblog my post? A: Yes, we will reblog every microfic that tags this account. Give us 72 hours to have it reblogged before reaching out to us about it. If we still have not reposted it in that time, then please feel free to DM or send us an ask about it.

Q: How should I incorporate the prompt into my microfic? A: Feel free to use the exact word/phrase in your work, or just use the prompt as a general idea. (Example: if the prompt is ‘not in the swimming pool!’ then you can use that as a quote from one of the characters, or simply write about a scene where something ensues that maybe shouldn’t be done in a swimming pool.) Q: What is the word count requirement? Does my microfic need to be a specific number? A: Microfics are generally anywhere between 50 and 500 words, but if you feel inspired to write something longer, then we encourage that as well! We have a sister blog, MACROCEST, that is for longer works.

Q: Can we join a prompt from microcest with other events? A: Yes! As long as it follows the rules of both/all of the events!

Q: Is faux-cest allowed? As in people not blood related partaking in roleplay? A: Yes! Faux-cest, step-siblings, step-parents, incest play, implied incest, etc. are allowed.

Q: I have an idea for a prompt, can I submit it to you? A: Yes! Send your prompt here!

Q: I have another question that wasn’t answered here. Is there somewhere else I can ask? A: Any other questions can be asked by sending us an ask on Tumblr or emailing us at [email protected]. All of our previously answered questions can be found here.

If you ever want to submit more prompt ideas anonymously, you can do so with this form, emailing [email protected], or via our ask box. Just make sure to note it's a prompt suggestion (otherwise I'll just get messages like "Dad, hurry up!" and it will confuse the hell out of me) and we will add it to our prompt list without posting the ask so it stays anonymous/a surprise!

I love incest that yearns like an open, throbbing wound.

You cannot be together with this person, no matter how much you want to.

Though they would, all of them, push themselves to the breaking point and past it without remorse for their people, their land, in the moments after . . . time can be spared to put one another back together.

Pairing:Jake x Lo'ak

Word count:947 words

Content warning/tags:sfw, incest/dadson, mentioned suicide attempt, angst, hurt/comfort, tsaheylu, kissing, canon divergence/missing scene ?

Author's note: for @microcest prompt 120: the morning after. ...the suicide attempt woa angst time. Also cutting it close to 1k...gulp 👀 im sorry they just mean so much to me.

Don't like? Don't Read. Don't want to see this content? Block me. :)

Jake noticed how Lo'ak stayed in his hammock later than he should.

How Kiri was silently following him, talking to him softly.

How red his eyes were.

It concerned Jake. Especially after their...conversation last night.

What he said was wrong, he knew it. Remebering he said it out loud to his son made his chest ache. He was just mad. Upset. They both were. And Jake knew that nothing he could say would fix it in the moment. Lo'ak wouldn't listen.

Though what Neytiri said made his stomach twist.

"...or you will lose another son."

Jake didn't want to think of all the different meanings of that sentence. It scared him.

He watches as Lo'ak leaves the mauri, his steps slow. Kiri follows soon after, keeping her distance.

Something was wrong.

He follows Kiri, catching up to her. He knew she knew he was there, so he didn't startle her when he placed his hand on her shoulder, turning her towards him.

"Babygirl, what's going on with Lo'ak?"

She stares up at him, words on her tongue. She swallows them down.

"He's...really upset...What did you say to him?"

Jake sighs, ears flattening.

"The wrong thing," he says, rubbing her cheek quickly before walking off to follow Lo'ak.

When he catches up, Lo'ak is curled up on the sand, leaning against a rock. Jake stares at him for a moment.

"Lo'ak," he says softly. Lo'ak tenses, glancing over at Jake. He doesn't move. Doesn't say anything.

Jake sits down next to him, leaning against the rock. He stares at the water for a moment before looking down at Lo'ak. He pushes some braids behind his ear.

"Can you look at me, please?" He asks, keeping any sharpness out of his voice. He didn't want to scare him away.

Hesitantly, Lo'ak looks up at Jake. Jake sees the red, wet eyes again and his chest aches. His ears flatten. He reaches up, holding Lo'ak's face in hand. He wipes away a tear.

"Why are you crying?" He knew why. He just wanted to hear it from the boy.

Lo'ak sniffled, pushing his hand away.

"You hate me."

Jake exhales softly, shaking his head.

"No...no I don't hate you. I could never hate you. I love you, son," he says, holding his face to look him in the eyes. Lo'ak lets out a sob. He shakes his head.

"No...you do. I killed Neteyam, and you hate me for it. You wish it was me," he mumbles.

"No." Jake says, his voice a little rougher than he intended it. He grips Lo'ak's face tighter. "No. No you're wrong. You're all wrong. It's not your fault. I don't wish it was you, don't say that," he says, softening his voice again.

"Don't lie..." Lo'ak whimpers, looking down as he sobs silently. Jake hates it when he cries. And he hates even more that he thinks Lo'ak looks pretty when he cries. Jake huffs. How can he get this kid to believe him...?

With one hand, Jake grabs his kuru, bringing it in front of him. Lo'ak looks down at it, staring at him with wide wet eyes.

"I'm not lying...show me how you feel," he says softly. Lo'ak stares at his kuru for a moment before grabbing his, bringing it forward. The ends open up. Jake takes a deep breath before they connect.

Their senses double, making the both of them gasp softly. It was always different with another Na'vi compared to an animal. Both their pupils grow.

Lo'ak gets hit with a wave of sorrow and pure love.

Jake gets hit with a wave of pain and sadness.

Then he sees it. Feels it. The gut wrenching feeling after being blamed. The idea of dying, the feeling of loneliness, the brief feeling of no escape, the gun under his chin and the hands of Tsireya and Kiri holding him after he threw the gun away, unable to go through with it.

Jake lets out a sob.

He never cries. Not in front of his kids at least. He's a marine. He suppresses his emotions, no matter how strong. At least...on the battlefield.

Lo'ak looks at him with surprise.

"Lo'ak..." Jake whispers, grabbing the boy and pulling him into a hug. He cries softly into the boy's hair, feeling overwhelming sadness from the both of them. It makes his chest hurt.

"I'm sorry, baby. I'm so sorry." He whispers apologizes to Lo'ak, his words jumbling out. He doesn't do that often.

Lo'ak cries softly, hugging his dad back. The two sit there for a while, soaking in their feelings. Jake rests his head on Lo'ak. He didn't want to let him go. Ever. Lo'ak feels this.

And Jake feels this overwhelming desire.

It's innocent, but desperate.

Lo'ak want's to make him proud, wants to be good. Wants to be held and touched.

Jake pulls back to kiss Lo'ak.

It's quick. To test his reaction.

Lo'ak stares wide eyed, crying softly as he reaches forward, kissing Jake again. It's slow, but passionate.

Jake could feel the joy that began to radiate from Lo'ak.

Jake kisses harder, deeper, starting to slip his tongue in. Lo'ak whines, letting Jake do what he wants. They pull away for air, breath tickling the others as they keep kissing. Their breath was hot and heavy, kisses deep. Lo'ak whines softly.

Jake can't help but think how erotic this is. He hasn't felt like this since him and Neytiri mated in the forest.

Being compared to his mom made Lo'ak moan, shuddering.

Jake liked that.

He keeps kissing Lo'ak, climbing over the boy.

He'd show him everything, because his baby asked him.

Appearances

A Chronicles of Narnia story for @microcest!

Prompt: your family is really close (from November 19th 2025)

(I first thought of something else that would have been super angsty, in a different fandom, then thought- Maybe something nicer. >.>)

T; 500 words Peter/Susan/Edmund/Lucy

The Pevensies have only been drawn closer to one another by the lives they've lived in either world - in both worlds - and so they remain, in whichever one they land, and whatever the expectations of others.

[kalira]

What Wasn't Lost

A Sex Pistols story for @microcest!

Prompt: won in the divorce (from November 26th 2025)

T; 500 words Yonekuni/Kunimasa

Being taken away, raised by their mother, has torn pieces out of Kunimasa’s once open nature, replaced with chill callousness - but here, twined close with Yonekuni, the warmth they have always shared can still be found.

(Sketchy on the 'divorce' part but given the 'taken away by one parent vs kept/raised by step-parent' feature in canon I figured it was close enough to count. >.> And a new ship!)

[dadfucker2]

I think brothers should kiss and i think it should be at once forbidden and electrifying and comforting and familiar. With tongue.

[purplestargirlll]

siblings who would NEVER EVER admit their feelings so they just keep teasing eachother in more and more sexual ways trying to get the other to snap and fuck them <33

[kalira]

Refuge

A Devil May Cry story for @microcest!

Prompt: I don't trust anyone else (from November 4th 2025)

T; 500 words Dante/Vergil

There is nowhere between the two realms, no spot of no-man’s-land however tiny in which to find peace, but . . . can there be, even in stolen moments, between two brothers?

[kalira]

Likeness

A Thor (MCU) story for @microcest!

Prompt: that's mine, take it off (from November 12th 2025)

T; 500 words Thor/Loki

Thor is used to his brother wearing all sorts of faces, and takes pride (and solace) in reading him beneath whatever illusion he puts on, but . . . please, not this one?

Because after some contemplations, I really wanted to play with the prompt in an off-the-wall way. XD
