The (possibly AU) Sibling Incest Meme

Incest is, despite its taboo nature in most societies, actually a pretty popular convention in both romantic fiction and works of a more erotic bent, in everything from period or fantasy pieces to series taking place in places like modern day Japan. Still, the most common configuration in these fictions are the pairing of siblings. Perhaps this is because of the usual lack of age difference and power dynamic that exists in child/adult relative pairings, though this is not always the case. Because of this, a sexual or romantic relationship between siblings can almost seem, well, romantic in the right light. Of course, more often than not, there's a dark side under the veneer of forbidden love.

This meme is for those who would like to play out that, either the darkness or the light - or both.

HOW TO PLAY

-Comment with your character and preferences. Be sure to mention any hard lines you have.
-Comment around to others. PLEASE NOTE THAT IN ORDER TO FACILITATE CROSS-CANON TAGGING, THIS MEME WILL BE CONSIDERED AN AU FAIR GAME ZONE. Feel free to comment in with characters who do not canonically have siblings or comment to people from other fandoms.
-Be respectful of others.

PROMPTS

1. Feeling Strange: You've known this person your entire life, yet lately you've been feeling...different about them. These feelings aren't exactly familial, either.
2. Not as Normal Families: Whatever the specifics of the case may be, your childhood was not the norm, and thus the two of you have grown close that way.
3. Raised Apart: Scientists believe that when siblings are raised together under normal circumstances, they will not find each other sexually attractive; however, if they are reared apart, they may be highly attracted to each other when they meet as adults.
4. Only Kin by Name: Psuedo-incest between step siblings or adopted siblings is not quite as taboo, but you could still be looked down upon for harboring those desires for someone who is a member of your family by one way or another.
5. Defender: One of you is older and has always looked after the other, meaning that something has grown between you that is thicker than any blood.
6. Guilty: You feel terrible for these longings toward your own flesh and blood, and you do your best to stop them. But can you choose who you want to be with? And how disciplined are you when it's someone you care for in other ways?
7. Dysfunctional: You don't have a good relationship as siblings, yet your relationship as lovers is great.
8. There's Nothing Wrong Here: To you, incest is a casual affair and the "forbidden" aspect is lost. Sorry you were grounded, big brother. Here, since you can't go out, let me be your girlfriend for the night.
9. Like Looking in a Mirror: The two of you are closer than siblings: you're twins. You share everything, so why is your love any different?
10. Skirting the Line: Stolen glances. Lips only a breath away. You're walking a fine line here. You haven't become physical...yet.
11. Got a Secret, Better Keep It: Needless to say, an incestuous relationship is not one that can see the light of day. You'd better keep it behind closed doors.
12. Jealousy: You can't stand the idea of sharing your beloved sibling with someone else, yet it's hard to make this known without blowing your cover.
13. As One: The obligatory smut prompt, whether it be the first time or one of many the two of you steal away.
14. The Things I Do for Love: You'll do anything to protect your love affair with you sibling and make sure no one interferes. Anything.
15. And You'll Be My Queen: It may seem as though the light will never come, but you want to make promises to your most precious sibling that one day, you'll live as any normal couple.
16. Anyone Who Isn't Us is the Enemy: You're in a dangerous climate, and the only one you can depend on is your flesh and blood - bringing you closer together.
17. No Choice in the Matter: Your sibling is not a willing participant in your debauchery, but they endure your cruelty, grooming, and manipulation because you are their brother or sister.
18. No One Like You: There truly is no one who can love you like the person who is closest to being you, bone of your bone. You perfectly understand each other and your love is pure.
19. Where No One Knows Our Faces: You've decided to flee your current life and live as new people among those who don't know that you're related.
20. Out in the Light: A secret no more, the two of you have decided to bring your affair out into the open. You will face the world, no matter what it does.
21. Rejection: Someone - friends, family, etc - has found out what you two have done and are disgusted by it. Will you turn to each other for comfort?
22. The End: Being with someone so unattainable is tiring, and one day, you may grow weary of stowing everything away, locking your heart up, or feeling so shamed. This must cease. But can you go back to being just siblings?
23. Not Really Related After All: Perhaps the most cliche of tropes, though it's often used to "justify" incest. Turns out the two of you aren't really siblings! Now, you can pursue a relationship freely.
24. Part of the Same Whole: You're meant to be together, you firmly believe it.
25. Sick and Twisted: The fact that you two are siblings actually is a kink/fetish for you. You get off to all of this.
26. FREESTYLE

{I can offer Natsuru here for an AU'ed younger (but taller and bustier) sister! They're both kind of similar in being awkward or modest or shy around others, but maybe they could be more comfortable and at ease around each other and things just... start to go in a "more than just sisters" direction over time? So to put it in prompts, 1 and 10 leading into 11, maybe with others?

Idk, I'm just brainstorming here, but let me know if you're interested!}

Katara 🌊 AtLA 🌊 OTA

[watermastery]

[breaksthelaw]

[Sun can't deny how freeing it is to be away from their parents. They have a little place on the beach and he and Katara are taking a vacation their. To their parents, there is nothing weird about. The two siblings are just going off for some fun in the sun together. But there is far more to it than that.

Sun and Katara have long since become intimate with each other. And when they are at home..they can't freely do things. But here? There wasn't a single problem with him openly kissing her on the mouth.

Right now for instance, Katara had woken up and was in the kitchen preparing them some breakfast. Sun got out of bed and was now standing behind her, arms coiled around her holding her against his body. He'd leaned his head over her shoulder and had her turns her enough that he could kiss her deeply.

It's small things like this that make a trip together so very worth it.]

[watermastery]

[ Waking up at the beach house is always nice, but it's so much better when the only ones there are the sibling duo. She let Sun sleep in and was almost done cooking up something, wearing nothing more than a blue silk bathrobe.

Katara smiles when she feels him holding her and prolongs the open mouthed kiss with a giggling moan. ]

Good morning.

[ She wiggles her hips so her butt slides over his crotch. Only for a few moments before she starts putting the finished omelets on the plates next to the stove. ]

Figured we might need some food after last night.

[breaksthelaw]

[He loves it here with her. The beach is a pretty big bonus. They would probably go out onto it at some point, but for now he was happy just to spend time in here with her.

A small grin quirks at his lips as she grindings her butt back against him. He presses his hips forward and grinds himself right back against her.]

Mmm. Not a bad idea. But maybe I should partake in a little bit more of what I had last night. [Not that he wasn't incredibly hungry. That omelets smelled really good too. His sister has always been a great cook.]

[watermastery]

[ Katara leaves the loaded plates where they're at and leans forward on the counter. ]

Oh, you liked that, huh?

[ She gives him a coy little smile. Here, alone, she can push what they've spent years slowly exploring. The back of her short bathrobe gets lifted up and her fingers dig into her butt cheeks, parting them far. ]

Come on and "Partake" of baby sister.

[breaksthelaw]

[Getting away with something like this while at home was next to impossible. But here, he drops down without even giving it a second thought. He turns his head and kisses one of her cheeks. His tongue comes out and swipes over the spot that he just kissed.

The next time she feels his tongue, its rolling over her anus. Slowly, he drags the wet muscles width over it, making sure she and he both savor the sensation. Then he slowly drags the tip of his tongue in a circle around the tight hole.]

Mmm..I still remember the first time I did this to you. It was right after we watched that video together in my room.. [It had someone rimming someone else. He'd noted the look in Katara's eyes when she saw it as well as the following anal sex. Well, a few days later, Sun was doing both to her for the first time.]

What were you thinking the first time your brother ate your ass? [He asks before licking it again.]

[watermastery]

[ Even the teasing's nice. They've got the vacation house and the time to enjoy it freely. Her tight ring reflexively twitches under his tongue.

Katara eases into her stance as he licks her over to ease that sensitive seal. ]

I couldn't believe we were doing what we saw. But it felt so good. It was the nastiest thing you did to me at the time.

[ She pauses to moan as he wets her anus with his tongue over and over. ]

Now it's really hot to think about you eating out your young sister's tiny ass.

[ Which she still is at the age of fourteen, but Katara's always acted more mature than she was. ]

[breaksthelaw]

[There are certainly a lot of things wrong with this. But everything wrong about it, Sun loves. It felt like out of everything they did, this was the most wrong. Like this would disgust people more than him fucking her pussy. That is something that makes this just that much more enjoyable.

He slides his tongue inside of her ass and slowly pistons it back and forth, making it push in as deep as he can. He's sure that their parents wouldn't let him come on his own, but Katara was seen as more mature and responsible. Little did they know she was doing something a nasty and wrong as this and she was getting off on it.]

[watermastery]

[ The pleasure she's getting from his tongue is building. She has to let go and hold on to the counter. ]

I love it when you tonguefuck my ass...

[ Saying it out loud, no parents to overhear that their daughter is so perverse, only adds to the experience for her. Unlike last night, it's during waking hours no less. ]

Hope you're enjoying your seconds.

[breaksthelaw]

[He places his hands on her cheeks to keep them spread and he starts thrusting his tongue into her ass even more quickly.]

Mmm.. say it again. Louder. [He mumbles before burying his face deeper between her cheeks to try to get his tongue in really deep. The wet muscle slides and rubs against her tight page, he swirls it around to let her take in the full feeling of it. No one was around the hear. Their spot on the beach from was far enough from other houses that they could yell and not be overhear.]

[watermastery]

[ Her heels raise up at feeling his tongue swirling around deep inside her hole, licking around fully. The wet sounds of her hungry brother too much for her to take in stride. ]

I-I love it when tonguefuck my ass!

[ He's clearly not stopping there and she's getting more into it from his demand. She has to scream it now. ]

You're tonguefucking your little sisters asshole! And I looove it!!

[breaksthelaw]

[He lets out a loud moan into her ass as she shouts her love for what he's doing. He pumps his tongue as fast as he can, wanting to make sure that she gets her fill on this sensation. He can feel how stiff he's growing underneath his own robe and knows that it is only a matter of time before he does more than tongue her ass.]

[watermastery]

[ Warmth washes over her abdomen. Katara's hand goes under the short bathrobe, fingers rubbing at the soft ache. She can't handle much more, but she doesn't go too quickly. ​]

Sun.

[ There's more and she knows it. ]

I want my brother's cock in my ass...

[breaksthelaw]

[He lets her enjoy his tongue for a few moments longer before he pulls it out of it. He runs the back of his hand across his mouth as he starts to stand up. Undoing his own robe, he's completely bare underneath and his cock is pretty stiff.]

I've never been one to deny my sister, have I? [Moving into position behind her, he takes it slow. But it's not that long before she'll be able to feel the tip of his cock starting to push into her ass.]

[watermastery]

Not in all the years I've known you.

[ She flashes a wicked smile, delighted to say such a thing aloud. All the poking, prodding, touching and licking they did are fond memories for her. Knowing how taboo every aspect of their relationship is just makes it that much hotter for her. ]

That's it.

[ Slowly, but surely, the tip fits into her eased up rear entrance. ]

Oh! So big...

[ She teases by circling her hips around so the tight hole twirls his shaft around by the tip. More. Katara always wants more. ]

[breaksthelaw]

[He lets out a soft groan as she swivels her hips and stirs around the tip of his cock in her. She's going to get more, she's going to get all of it. He presses forward, shoving more of his cock slowly inside of her ass.]

Starting to do stuff like this together was the best decision we ever made. [They could have stopped before things progressed too far, but they didn't. They kept going and now they have a deeply intimate relationship where they have probably done more together than even his friends had with other girls.

Soon, his hips are pressed flush against her ass with his full dick inside of her.]
