DISCLAIMER: Although the Inuit are a real ethno-cultural group, the characters of Inuit descent in this story as well as the sexual customs of their family are entirely fictional. Their particular ancestry is mentioned only because traditions already attributed by some to the Inuit provide a conveniently plausible origin for customs which appear quite deviant from a Western perspective. The author knows of no actual instance of such customs among modern Inuit people, and regarding what may have been practiced historically, the author encourages thorough research before any judgment is reached.

My family is very unusual, but not in a way that I would ever dream of complaining about. Until just a couple of generations ago, we were all ethnically Inuit. While my grandparents' generation brought the first infusion of European blood into the family, our cultural Westernization had already been mostly complete by then. The one major relic of our legacy that remains is a rather unique syncretic development. Long ago, wife-swapping was not uncommon in our tribe and often served to develop or strengthen bonds between otherwise unrelated families. As our ancestors assimilated, this custom somehow managed to linger, though in a curiously altered form. Rather than forging a kind of kinship between multiple families, it morphed into an expression of solidarity within each individual family. Upon a couple's marriage, each spouse is at least permitted if not gently encouraged to be sexually available to the other spouse's siblings. In essence, the sexual satisfaction of both spouses as well as their brothers and sisters, indeed even procreation, is viewed as a cooperative family effort. There is never any compulsion, of course, but there is no guilt either. Everyone is also encouraged to be very honest about their feelings to ensure we're all genuinely comfortable with the arrangement.
I use the term "siblings" a bit loosely here, since an obvious consequence of this lifestyle is that at least some of the family's legal siblings are in fact what we call "couslings," or biological half-siblings/half-cousins. Any child not sired by his/her biological mother's husband is usually adopted by that husband shortly after birth. A mother who is herself unwed has the similar option of letting her baby's biological father's wife adopt him/her. However, this is mostly just for the purpose of official guardianship. In actual practice, extramarital parents play as great a role in their children's upbringing as they are able and willing to play, which is often considerable, with aunts and uncles tending to be about as involved and invested as moms and dads.
The overall close-knitting of our family might explain the other major aspect of this lifestyle that would likely shock outsiders, namely our lack of concern for privacy. When scratching the erotic itch, none of us care whether any other adult kin are in the room or not, and any incidental witnesses reacted with amusement or encouragement at most. At least in my immediate branch of the family, this may be one of the things that led to a new development in the tradition, namely a kind of general "Help yourself!" attitude. Each participant in the tradition is always assumed to be at least passively receptive to sex by default unless he/she either states otherwise in the moment or is known to be exclusively committed to a partner outside the family.
As one might expect, few if any of those who've married into our spouse-sharing clan reacted with anything less than shock when they first learned of this custom. Still, even we are surprised at how relatively easily they come to embrace such a controversial proposition. Then again, precisely as a result of our upbringing, we may naturally be drawn to partners who are just liberal enough to at least hear us out on the matter. I suspect that what helps the most in easing new members into it is being able to observe just how genuinely close we all are with very little if any of the rampant jealousy they expect. Even among those who were initially quite uncomfortable with the idea, some grew more open it at their own pace. In any case, for the majority who agree to participate at some point, a kind of initiation ritual has evolved. It can be carried out (and rescinded) at any time but usually occurs shortly after a newlywed couple's honeymoon.
We call it a "self-presentation," and the one that's freshest in my mind happened just about a couple of weeks ago. I had just returned from a Hawaiian honeymoon with my wife Allison, a down-to-earth woman with piercing hazel eyes, long auburn hair, firm 42D breasts, and an equally curvy butt. Just a couple days after returning to our large but cozy condo, we helped my younger brother Tim and Allison's younger sister Savannah move in with us. We lived very close to the university they both attended. Tim had originally insisted on experiencing life in the dorms, but after a string of party-animal roommates, he'd finally had enough and decided to take me and Allison up on the offer that had been on the table since his high school graduation. On her part, Savannah was just starting college and was never as enchanted with the prospect of on-campus living as Tim was, so when she found out we had room for her as well, she saw no reason not to take advantage. We had just spent the better part of the afternoon bringing their various belongings in, rearranging things a bit to accommodate them, and unpacking at least the most important stuff. We were sitting at the table in our polished chrome kitchen, finishing up the pizza that Allison had ordered when we realized how famished we were getting, when it happened. My lanky brother was telling yet another horror story about one of the stunts his last roommate had pulled.
"I mean, I'm totally used to Kevin and Olivia going at it right in front of me, and even I didn't want to see that!"
I chuckled at his reference to our older brother and his wife. "Just used to it? Please, bro! It clearly turns you on. Not that I blame you, mainly because Olivia's gorgeous, but especially because she's as open to you and me as she is to Kev."
"And on that note..." Allison said, meeting her sister's gaze with a sly smile as they both rose from their seats. "We've made a decision."
Tim and I exchanged a look of our own before turning back to the girls, doing our best not to let our nascent excitement show on our faces. If this was going where we both thought it was going, this living arrangement would be even more fun!
Allison and Savannah briefly argued in whispers over who should proceed first before Savannah conceded with a roll of her eyes, which elicited a cute giggle from Allison. My 18-year-old sister-in-law, a slightly mousy redhead with curves to rival my lovely wife's, faced me with a soft blush on her cheeks. She unbuttoned and unzipped her jeans, and I felt my mouth go dry. "Nathan Daniel Kutipta, if you'll have me, my name is Savannah Rachel Leddar,..." In a single, sensual motion, she pulled her jeans and panties down to rest just above her knees, "...and this is my vagina."
Vaguely aware that Allison was now performing the same rite for Tim, I couldn't resist licking my lips at the sight before me. Lodged between two beautiful thighs extending from exquisitely flared hips were two smooth labia tucked neatly into a short genital slit, adorned with a thick patch of dark red hair. I swallowed, looked up at her with a smirk, and reached out to touch it. Blood was already pooling southward, and the way she immediately let out a soft moan as I gently stroked her exposed pussy hardened my own genitals even further. I stood up and kissed her on the mouth and simultaneously started massaging her breasts. She purred into the kiss, squeaked when my hands first cupped her mammary melons, and moaned again as I moved my lips to her jaw. I trailed only three kisses down her neck before something inside her snapped, and with an impatient "Ugh!" she was promptly unfastening my cargo shorts. Her own urgency abruptly catalyzed my own arousal as well, and she had barely managed to expose my now fully erect penis before I reversed our positions and spun her around in a single, desperate move. She instinctively leaned over the table, her round butt presenting an irresistible invitation. In the corner of my eye, I amusedly confirmed my suspicions that much the same was transpiring between a desperate Tim and Allison, but my attention instantly returned to Savannah. I was inside her before I knew it, and I placed both palms on the table for leverage as I immediately began thrusting. She was already moist as I entered her, and her gasp only made my need to penetrate her even greater. Her tight pussy hugged my shaft as I withdrew slowly and attempted a deeper venture.
This repeated only a few times before she apparently grew tired of my gentle approach. "Oh, quit being a tease and pound my ass like you frickin' mean it!" she demanded.
Her directness, coupled with the fact that she clearly preferred it fast and hard, had me reeling, and with a primal growl, I immediately let loose and accelerated my thrusts to a speed more like what my instincts were crying out for.
"Augh!" Savannah's breath caught in her throat as she got what she wanted. "Oh, yes! That's it! Mmm!"
So I carried on with more or less the same momentum. After about five minutes, my member was practically covered in her natural lubricant. I gripped her hips and just kept ramming my cock into her, and I could feel my semen pooling in my glans and building up pressure. With her intensifying purrs and moans, Savannah wasn't making it any easier to keep a lid on it, and when she let out a particularly warbling cry of bliss, I knew release was imminent. "Where do you want me to...?"
"Just cum inside me!"
With a drawling grunt, I shot multiple hot jets of seed deep into her pussy, my hips spasming against hers with each explosion. On the heels of that came the loudest moan I'd yet heard from her, and I can't be sure, but I think I felt her hips spasm a few times as well, which was a good sign.
Breathing heavily I bent over and rested my torso upon hers as Savannah emitted a couple of half-moans/half-sighs indicating something like contentment (hopefully, anyway). "Do you need me to do anything extra, like, with my mouth or my fingers?" I asked.
"No," came the still slightly breathless reply. "I'm good."
I nodded against her back, and after a few seconds of noticing that Tim and Allison had finished shortly before us, I lifted myself off Savannah, who rose with a shiver and turned around to face me once more.
