Future home of my Relationshipping 2025 creator letter

Thank you so much for being my match on this exchange! I write a lot which can be overwhelming, but other than DNWs, please feel free to ignore it. It's mean to inspire, not overwhelm.

Please write whatever we matched on/whatever inspires you. Literally everything else here is just to help give you ideas/guidance. If anything squicks you, doesn't spark joy, doesn't inspire you, etc., ignore it! I like a ton of things. Please don't feel like you need to match my level of kink. (Unless you want to!)

For convenience, here is a link back to my sign up.

First I'll touch on pairings, then there is a list of my likes/dislikes.

Tangled (2010):

Any way you want to make Rapunzel and Eugene related is fine by me. It can be AU or since he's an orphan it could be that Frederic got frisky with a lady one night and never knew, or even Arianna and Frederic got pregnant pre-marriage and to avoid a scandal they gave him up. (Maybe Frederic never even knew.) I'd like them to discover they're siblings at one point and it'd be nice if that just made them even more horny for each other.

For Frederic/Rapunzel, I'm seeing this more in a "you got away from me once, so never again" sort of way, where he's dominating and controlling her because he doesn't trust anyone else, but I am also totally open to other scenarios. I am fine with this being a little fucked up or even non-con if you want. You can also have Eugene rescue her at the end (or not). Or you could combine them so it's brother!Eugene/Frederic/Rapunzel, whatever level you want.

Star Wars:

My interest here is obviously Luke/Leia, so I really want to make sure they are fucking each other. If a third is involved, that's great, but I want to make sure Luke's got his dick in Leia's cunt at some point. I prefer if Han or Lando is involved they either fuck Luke while Luke is fucking Leia or fuck Leia's ass, so Leia's pussy is exclusively Luke's. But I won't force you to do that, just my preference. They don't know they're related during the Jabba scenes so feel free to go AU or have them recaptured or somehow find out if you go there. Feel free to go noncon creepy if you go the Jabba route. Otherwise, I am open to anything. You can do domestic happy-ever-after, or sex pollen, or something more complex. I love the twin-aspect for them, the idea that the Force created them so that they could be together. I like the idea of the Force making them male/female twins so they'd have more powerful Force users together, etc. I like the telepathic closeness, the psychic link between them, and I imagine the sex would be just incredible. I like the idea of Han or Lando being in awe of them and basically honored to just witness their love making. I am fine with an actual threesome, but could also very much enjoy like cuck!Han.

I like them coming to terms with their incestuousness, but I also like stories where it's not a big deal. Ultimately, I want it to be loving and excellent. When they finally give in, it should feel like the Right Thing, the Light Side of the Force, etc.

Harry Potter:

Percy/Ginny is my guilty pleasure. I've written it, I always request it, sometimes I even get it. I've decided to also ask for Bill and Charlie with them, because I'm starting to see the potential for them. They're arguably older and wiser and could be good guidance. Plus, Ginny getting reamed by two brothers is extra delicious. I generally imagine either sex pollen/magic spell gone wrong, or else an AU where Voldemort wins and makes Ginny into a pure wizard breeder for her brothers, but I am totally open to other scenarios. (I prefer something a little more in depth than "sneak into her room at the Burrow" but I will take whatever I can get.) I'd love to see Ginny be the aggressor and Percy too meek or mild to resist. I'd also love to see calm, prim, proper Percy just absolutely lose it looking at his naked little sister and just destroy her. (Ginny's probably sexual active pretty young, based on the books, so I like the idea that she thinks she can take it, but then Percy is just like SO Much.) I'd prefer if it turns out to be Really Really Really good sex, somehow. Like, maybe Ginny's shocked how good it is. Or they've both long harbored incestuous feelings for one another and some true potion lets them be free and it's like a million times better than anticipated. (I've sometimes thought that Ginny secretly crushed on Percy and since Incest Is Wrong she transferred her impossible incest crush to an impossible crush on The Boy Who Lived instead, but really it's always been Percy she wants.)

If adding Bill or Charlie, I am open to various scenarios. Sex pollen/sex magic still works. Or they can go visit and get wrapped up in craziness, or maybe one brother catches the other brother with her and that Leads To Things. Or one brother teaches the other brother, etc. I'd really really prefer Percy in Ginny's pussy, but they can swap. I am also fine with Percy or Ginny getting it in the ass while Percy's in Ginny's cunt, etc. Honestly, just have fun with this!

Beauty and the Beast (Animated):

This is definitely for the Disney cartoon, not the live action movie. I am content any way you want to make them related. I think it's not too hard to imagine Belle as Adam's little sister and when the curse happens Maurice (not her real father) smuggles her out of the house to save her from the curse and raises her as his own, etc. But you can come up with any sort of story, even something almost original with the basic trappings of the animated film. I would like them to discover they are siblings within the context of the story, and I'd like them to have sex. (It can be beast form or human form, or both.) Generally I like the incest aspect to make them hornier for each other, but there can also definitely be a period of shock and horror. I don't have a ton of ideas for this, I just like the idea of it, so please have fun with it.

Labyrinth (1986):

Jareth as Sarah's father? Oooh!! This could be an AU where it's always been the case, or a sequel where he reveals the truth or something. In the film her father is her father and the mother is the step-mom, but you could easily reverse that. Or even something like Jareth seduced her mom when her mom was younger and he's her real dad. It should obviously be revealed during the course of the story. I think Sarah would be horrified by it, but also maybe a little turned on.... like, she's so different from the dad/family she grew up with... is she really the daughter of the Gobling King? Is that why she is the way she is? Maybe Jareth doesn't even know until later... so many angles you could go with this. Is she his heir? Does she want to rein there? Is there more to than realm than just the Labyrinth? Is it real at all or just her (sexual) fantasy world? Perhaps the rulers of the Labyrinth always marry/procreate with their offspring. The opportunities are endless!

Mighty Morphin Power Rangers:

So I have this thing where I take all my favorite pairings and make them incestuous if at all possible. This was my favorite childhood pairing. I would love to see some incest between them. It's easy to make them half-siblings sharing the same dad. (Just have Billy's dad knock up Kim's mom in secret.) If you want to make them full blooded without going AU, you can have Billy's dad knock Kim's mom up while Billy's mom is sick and dying. She has Billy in secret and he passes the baby off as his recently dead wife to all neighbors (and to Kim's mom's husband). Then he does it again and this time she keeps Kim and raises her. (Or maybe they were twins and somehow one family raised one and the other raised the other but didn't tell?) You can also go AU, make them siblings some other way, or use some Power Ranger magic that makes them siblings. Ideally they'll discover that they're siblings at some point during the story, and it'd be cool if the sibling reveal is part of what makes them fall in love. Like, somehow knowing the truth makes it hotter? idk. I'd love to see you also touch on how the morphin grid plays into their romance, like being siblings AND being able to touch the morphin grid makes the sex super hot/intense? I'd love to see them fucking as teenagers and I'd love to see them married with incest kids... maybe no one knows they're siblings except them? Maybe they move to Aquitar, idk. Have fun with it!

Original Works:

All the original work are either Father/daughter or older brother/younger sister. Most of the pairings are prompts in of themselves, so feel free to use them plus my likes/dislikes to craft something suitable. I tend toward more fantasy or scifi than mundane ("brother comes home from college" sort of thing), though I do also like that at times. I do like underage for the girl (as young as a sexually mature 12, but over 18 or no-age-mentioned also fine). For non-con scenarios I prefer a "no no yes" approach where the resistance is eventually won over (either willingly or via brainwash/sex pollen/whatever). Feel free to mix and match prompts as well as kinks/likes. Have fun with it!

The Last of Us (video game):

I shipped these two pretty hard when the first game came out, they already have such a great father/daughter vibe. Initially I thought maybe Joel had knocked up some woman he didn't know about and that's where Ellie came from, so I guess that's a route you could take. Or you can go AU where they've always been father/daughter. It's interesting to think about how that'd change the dynamics. Having them learn the true later would maybe make it fit more into canon. I know Ellie is gay in the later games, but I am happy to have her be bisexual or gay-but-also-Joel-sexual, or whatever you'd like. I'd like it to be more than just Joel pining over her and hating himself for doing so. I'd like Ellie to be very into him and maybe even the one doing the seduction. How about an AU where he gets her pregnant and that's how they discover she can have immune kids or something? I think my preference is to ignore or go AU from the second game, but obviously you do you. I have seen the TV series so you can incorporate some of that lore into the story, but I prefer the game characterizations more.

Crossover:

So, this is the extra dirty-bad-wrong version of Luke/Leia. Leia's only ten in the Obi-Wan series, so if you select this and do something sexual, I'd like you to age her to at least 12... but I'd really love to see you do something sexual with them. Time travel? Dimension hopping? Groundhog day? Magical Force projections? Alternate timeline? Your choice. Give me adult Luke with very young Leia, any way you can slice it. I'd love to see Luke guilting even more than usual over being with her, but also really really loving it. I'd like Leia to be young but assertive, maybe even being the one to seduce him. (Maybe she's at the Imperial academy and he's pretending to be a professor or something to infiltrate for a time travel mission?) I'd like them to both know they're related/twins if they have sex (and please see my other Luke/Leia prompt for how I like that), but Leia can get mind wiped or mindblocked or something if you want it to retain canon. I am also happy with some sort of canon-breaking AU where old Luke stays in the past with her and somehow everything works out. Feel as creative and plotty as you want, or just one-off porny. Hell, it could be as simple as a hot porn dream one of them has. Thank you for even considering this almost crack pairing!

Thank you again so much for writing for me! Below you will find a big list of my likes/dislikes. Please feel free to pick and choose from them. Do not feel like you have to include everything.

NSFW DNW:

- mpreg (it can exist in universe, if needed, but not for my main pairings)

- cum play (fertilizing eggs, yes. Gushing or leaking out, okay. Playing with, eating, bathing in, handling, kinking-on, no.)

- older woman/younger man sex scenarios (unless specifically requested)

- piercings other than ears (unless canon)

- "all-incest culture" (I love incest, but if it's not 'taboo' for the majority in-universe it loses its appeal)

Things I don't mind that others often do:

In universe canon divergent, mundane AUs (I want it to still feel like the characters, and I want the relationships to be intact), incest, underage (12+ for girls), A/B/O AUs, bestiality, kidfic/curtain fic (so long as there's still some sexytimes with the main pairing). Tropes are also fine! "Have to share a bed" or "keep warm in the snow" or whatever other stuff you love? Totally down for it. I tend to like rare pairings that don't have fics with these tropes, so add a sex scene and go for it.

Here's the deal. I would love some kinky, crazy, off the wall hardcore wild hentai logic sex. But I am also fine with something more run-of-the-mill. I am going to be happy either way, I promise. Write what you want to write/what you're comfortable with writing. Just because I list permanent cervix dilation as a top kink doesn't mean you have to do that if you're totally squicked by it. Write whatever we matched on or whatever inspires you.

You are also very welcome to mix-and-match or combine prompts and scenarios, even between fandoms.

Okay, that's it! Please have fun with it! Don't let my sexual depravity scare you off. Write what you're comfortable with. Also feel free to comment anon if you have any questions. Thank you so much!

Treats are always very welcome.
