[Futa4F] The sisters who sleep together, stick together.

NSFW

(forgot to edit the title but down for Futa/Futa as well as Futa/F!)

"hey"

On its own, it was a pretty simple, innocent text between sisters. Nothing out of the ordinary about it - just one sister texting the other, probably to chat about something.

"I really wanna cum."

That part was neither simple, nor innocent. If anything, there was several layers of baggage to unpack there.

"i'll be fast, i promise, i just like can't focus at all on studying rn"

And, somehow, back to something simple. A little sister, politely begging for help from her big sister. Nothing out of the ordinary there either, really. If anything, a sign of a healthy relationship between siblings.

"God, okay, sure. I mean, I'm not really doing anything I can't do later, I guess. You're lucky you're cute when you cum. Where are you?"

Once again, a rather stereotypical response. The big sister who's a little annoyed with her little sister, but is still gonna drop everything to help out of love. Sure, maybe she was feeling frisky and half considering messaging her little sis herself, but she'd absolutely never admit that.

The two had been fuckbuddies for a while now, to the point where it was a break in the routine if the siblings didn't get each other off on any given day. Granted, that left a lot of maneuvering to keep things under wraps, mostly trying to act cool around anybody who knew the two were sisters. That didn't stop them from taking risks though, whether that was fucking in a bedroom at a party or sneaking away from their friends for a quickie, just to play it off when the two returned.

That didn't even mention their parents. As far as they were concerned, the sisters were close and helping each other deal with being away from home in college. That was the reason they always seemed to be together whenever they'd call on the weekends. It certainly wasn't because they spent all day in one of their bedrooms, orgasming away the stresses of the week and reaching new levels of depravity just about every time.

Even more so, they had to play it cool around people who didn't know. There was a thrill in getting touchy in public to begin with, and more of a thrill in doing it when you were related. The risk was, of course, somebody happening upon them making out at a club, or the little sister feeling up her sibling's tits on the sly.

Neither would admit how much they loved it, and they really tried to play it off as "siblings who happen to fuck" rather than "fuckbuddies who happen to be siblings", but they both knew deep down what the real situation was.


Hiya! Thought this would be fun. It's a pretty basic idea, a younger futa sister who's fuckbuddies with her older sister. I think there's lots of fun to be had in figuring out what their relationship is like, how it started, all sorts of fun stuff. I'm sure we can cook up some drama between the two if we like - maybe the little sister gets a crush on a classmate, and the big sister is offended by that for a reason she doesn't totally understand.

I have been itching to play a romantic angle on this - not only are they sisters, they also happen to be completely head over heels for each other, and are grappling with that level of taboo on top of the "having sex with your sibling" taboo. We can discuss what level we want to play this at, but there's something so fun to me about two sisters basically dating even despite knowing it's "wrong", because they're just that into each other(and the sex is amazing, obviously).

If you could include a little tidbit about what your favourite TV show is, as well as preferred cock/ball/breast sizes, that'd be great at giving us something to chat about(and it lets me know you read the post <3).

I have plenty of refs I'd be happy to send, so just ask and I can send you the albums. Please note I do prefer photo refs over art. Finally, my kinks! Do let me know what you like/dislike, or if there's anything you might want to add!

Kinks: Big/extra big cocks and balls, pregnancy, impregnation, bulges, distension, tons of cum, cum inflation, spanking, public sex/teasing, freeuse, name calling(usually sweet/cute names), cock worship, non-penetrative sex(titjobs, handjobs, etc.), lactating, tight clothes, teasing, casual sex/nudity, dirty/crude talk, outfit control, edging, sub futas, soft doms, probably more!

Discord is my go-to platform for RP these days, so would love to move there if we think we'll click and have fun!

Hope to hear from you!
