Let me say up front that our mother is a religious psycho, but that is a distinct improvement over the extremist views she once held dear. She and my dad were once part of some bizarre religious sect that was probably only a few gallons of kool-aid short of a Jonestown-style mass suicide. But when the old man seemed bent on making Jezebel, my then 7 year-old little sister, his next "wife", mom went ballistic and damn near beat him to death with a shovel. Mom was acquitted of wrongdoing when the courts accepted that her "episode" was driven by a need to protect her children from a paternal pedophile.
We moved to another distant rural religious commune where Jez and I were allowed only little bits and pieces of outer-world information once our mom deemed them suitable for our consumption as mom home-schooled us until well into our adulthood when she thought Jez and I to be old enough and wise enough to venture into the sinful world outside the commune walls. And even that didn't happen until we were in our early 20s. Being legal adults didn't mean anything to our mother; we were still treated as children until she decided to grant us "adult" status.
Life in a sexually repressed home, cut off from most of the modern world, isn't always as bad as it seems. Jez and I didn't really have any friends, so we formed a bond that to this day remains stronger than most marriages could ever hope to achieve. One of the things that has kept us bonded is our dependence upon each other for mutual sexual fulfillment.
Yes, you know it as Incest. But to Jez and me, it was our only real ticket to sanity for a very long time.
The very nature of the commune meant that we had to share meager quarters that kept Jez and I in the same bed all the way to adulthood. Mom was confident that nothing was happening or going to happen between my sister and I given her strong religious teachings and threats of us being struck dead in an instant from some god if we dared to engage in "carnal knowledge" with anyone. And truly, until we realized that we had become adults in every legal sense of the word but still not in our mother's eyes, nothing happened.
But the need for human sexual contact has a mind of its own, and sleeping in such close proximity with another sexually blossoming body will generate some pretty basal hormonal and physical responses. Jez and I were taught very early the basics of human biology and sex and pregnancy. Fearing that mom would likely beat both of us with any of the vast array of farming and gardening implements should we ever make the mistake of engaging in true sexual intercourse, we instead focused on simply pleasing each other every other way possible.
Jez and I developed a natural recognition of each other's pleasures and desires. Self-gratification quickly evolved into mutual masturbation as our hormonal need for sexual exploration left us to freely learn of the opposite sex from the other whenever privacy became available, usually when mom had to go into town with some other elders while leaving Jez and me "safely" at home.
It didn't take long for me to learn just how sensitive Jez's nipples were and how much she enjoyed having me suck on her breasts as I probed her steamy vagina with my fingers. She was especially responsive when I would find her little nub and gently roll it between my index finger and thumb while I chewed on her rubbery nipples until she would wrap her arms around my head and pin my mouth to her teat while her body would shudder and her vagina would let loose with a stream of slippery fluids.
Not one to leave me without pleasure, Jez took particular joy in having me straddle her tummy, watching with focused interest as she pulled back and forth on my rock hard penis. When the little drops of clear, gooey juice would work their way out of the tip of my manhood she would pull the head of my member to one of her breasts and smear the drops onto one nipple, and then the other when the next few droplets would emerge. This only excited me more and quickened my need for the ultimate release at which point Jez would stroke the length of my manhood with both of her hands as my testicles swung freely and danced back and forth on her tummy until I could hold back no more and my penis would explode with streams of gooey, white semen all over her beautiful, round breasts to her obvious delight. She would continue to work at draining my member of every drop of my seed and then rub the fluids into her skin with both my softening penis and her expert fingers.
But our sexual life made a significant turn for the better the day that Jez's deft hands drew from me one of the most intense ejaculations of my sperm that not only coated her full breasts with gobs of my pearlescent seed, but her pretty, smiling face as well. When I saw my ejaculate clinging to Jez's face, I found myself torn between a fear that she might be repulsed by my massive seminal eruption and a deep-seated thrill from seeing my fluids sprayed on my sister's lips and chin. My fears were short lived when Jez licked my sticky seed from around her mouth and smiled with a new excitement. At that moment she pulled me by me penis to her face and without further hesitation took my sperm-smeared member into her mouth and sucked on me like some sweet treat as she cleaned my staff with her mouth and tongue with an enthusiasm that she later told me brought her to another orgasm without her vagina even being touched.
Our once-in-a-while union became more frequent as Jez developed a literal hunger for my seed. The preamble of Jez's manual manipulations of my manhood quickly faded in favor of her hunger to take my throbbing member directly into her hot mouth and feasting on me, craning her neck to work her mouth as far down my rock-hard penis as she could before nearly choking herself on it until the room around me would begin to swirl and my body felt like a quivering mass of gelatin until my penis would erupt in a geyser that I feared would drown Jez.
But Jez learned to swallow my seed; to swallow every drop my burning testicles could produce and still suck hard upon my aching manhood in search for more. Jez's near insatiability eventually evolved into Jez developing a talent for taking nearly my entire length into her mouth. And even that took on a new dimension when Jez wasn't satisfied with simply sucking my penis into bliss, but it progressed into a need for her to feel me thrust myself into her mouth, driving my manhood into her waiting and willing throat much as any man would thrust into his wife's welcoming vagina and pushing past the boundaries of her throat until she would again take me to the heights of pleasure that I now lived for and my semen would flow freely and feed my sister's oral lusts.
Then came the day that we introduced ourselves to the most forbidden stage of our ongoing union. Even more taboo than the actual act of coitus.
