Author's note: The universe/world this story is set in was not of my own invention. It was originally created by an author known as "cuteycindyhoney" on another website dedicated to Futanari erotica. For those who don't know, futanari (also known as "futa") are fully-formed hermaphrodites. I initially wrote this story as part of a contest, with CCH's permission to use her universe with the provision that I create unique characters. Since then, I've been slowly working on a Part 2 for this, which I will post soon.
I KNOW that there are some biologically impossible things in this story. If that's a turn-off for you, then please feel free to back away and go read something else. This is pure fantasy and sci-fi that is meant to play on the imagination and has absolutely nothing to do with reality. It's supposed to be FUN and if you can't have fun with sexual themes then, really, what's the fucking point, right? So sit back, turn off your inner biologist/scientist/skeptic and please ENJOY this decidedly weird romp!

Auto-Genesis, Part 1: Shawna and Eve
Ever since the Dryden Disaster, life on Earth hasn't been the same. Billions of women went to sleep one day feeling like they had a bad cold and woke up the next day feeling much better and very different- they'd all grown penises literally overnight, while they were sleeping. Of course, these women didn't all change on the SAME day, but each woman who was affected told the same story- went to sleep normal, woke up with a massive penis. At any rate, these new appendages were far superior to anything a human male could possess. These phalluses were longer, thicker and the seed they produced was infinitely more virile- a single drop was certain to impregnate a woman. These changed women were healthier, stronger and longer-lived than anyone could have imagined. And their offspring proved to be every bit as enhanced and endowed as their progenitors. Eventually, such endowed women were commonly referred to as "futanari", which is a Japanese word that basically means hermaphrodite.
This magnificent change in the world was brought on by a virus that had been created by a Doctor Mary Ellen Dryden. She was a highly gifted geneticist who was, at the time, working on a way to virally immunize Humanity against all forms of disease and sickness. She was also, as far as history can ascertain, the first real human futa and, as such, lived in loneliness. She didn't really fit in anywhere and had to keep her dual-sexed nature a secret. She was so lonely, in fact, that when she created her wonder-virus that would save Humanity, she keyed into it pieces of her own DNA. Her intent was to have other human beings who were genetically predisposed to sharing her genetic code catch the virus and become like her. She'd made a mistake, however, and what she thought would affect only a handful of people on the planet ended up affecting 100% of the Human female population- those who didn't grow cocks of their own had inherited, via the virus, an elasticity in their bodies which would allow them to accommodate the massive futanari phalluses. This mistake came to be known as the "Dryden Disaster." Despite the best efforts of every qualified scientist on Earth, there could be no cure; the damage was done. Humanity was healthy, but it came at a cost.
Men soon became obsolete as the generations wore on with more and more futanari being born and fewer males. By the year 2230, no males were being born at all and the men of the Human Race became extinct. Futa women now carried on the species. "Mono" women were still being born, but their numbers, too, were dwindling as years wore on. It was a foregone conclusion that, eventually, the dual-sexed futanari humans would be the only representatives left of our species.
With such a fundamental shift in social and sexual mores across the globe, nothing could be expected to stay static. Sex became such a pervasive and integral part of everyone's daily lives that very little was considered "off limits." Young futa getting pregnant by their own sires or impregnating their own mothers, sisters marrying each other, midday siestas meant solely for fucking as a way to relieve sexual tension... things that would have sent any average person from a mere hundred years earlier into apoplectic fits were now considered so normal that no one could imagine living any other way. Families were tighter and the bonds between them were stronger than ever before, due largely to the fact that sexual taboos had all but disappeared.
But not all of them. Or, rather, some NEW sexual taboos had been created. One in particular: self-impregnation. Futanari were able to impregnate themselves with incredible ease. Most who suffered this indignity would do so accidentally, usually during masturbation sessions wherein semen got inadvertently introduced to the vagina, either by careless fingers or errant shots of extremely potent cum being shot in unexpected directions. Sometimes, and there were only a handful of these cases, the use of portals came into play- some futa, most of them very young, actually used these micro-transport devices to have sex with themselves and lost control of their faculties at the wrong moments. Unfortunately (or fortunately, depending on your perspective), futa sperm is considerably more potent than normal semen from a human male and futa ovum are also considerably more susceptible to insemination. It's a true miracle that auto-insemination doesn't occur more frequently, considering how prone a futa is to procreation. Nevertheless, self-impregnation is generally considered a true failure of common sense amongst most people in the world these days. If you somehow managed to get yourself pregnant with your own sperm, then surely you aren't bright enough to get along in the world- that's the subtext of the ridicule that greets virtually all futa who knock themselves up. Of course that's not always true, and most people recognize that on an intellectual level, but people being people, ridicule often has very little to do with logic.
