Nikki's Code

Story by nothingmore

As a part of a shady experiment, Nikki's stepfather, a biochemist, artificially inseminated a colleague with human compatible DNA found embedded within a meteorite. Her fetal development was remarkably normal as she came to full term 17 years ago, at which point her stepfather proposed to her mom. Raised human and appearing otherwise normal, she discovers a profound difference during her first adolescent orgasm. Intense climaxes occasionally grant her momentary access to re-code her genetic sequence to accommodate her desires, given that they align with the needs of her alien element. Her initial interest in women brings one rather obvious change, though, despite being uncommonly bright for her age, her true nature remains a mystery.

***Warning***

The prologue is just a solo scene with a futa on girl fantasy, introducing the main character and what she's all about, but following chapters will contain futa on male and/or male on futa, some of which is futa pov. Also, the main character has no balls (internal testes and ovaries) in case that isn't your cup of tea. Drafts for Ch. 2-4 are in progress, but I’m not a writer so my pacing could probably use some work. I welcome any critique, suggestions, and/or requests, but otherwise I’m just going to wing it.

I take my first conscious breath, stretching my arms out lazily as the new day greets me with the familiar bittersweet ache of morning wood. My down comforter is clearly losing a battle against my altered girlhood as it pitches a tent big enough to smuggle a small cat. A damp spot soaks through at the summit, keeping the local dry cleaners in business. Really, it’s no different from any other day since this change was set into motion, aside from my head feeling foggier than usual. But another sensation takes immediate precedence. Goddamn it, do I have to pee! I usually avoid liquids before bed, having learned what a full bladder, combined with frequent nighttime erections can do to one’s sleep schedule. But more is to blame this time. I went on a bit of a bender last night, demonstrated by the fact that I’m still feeling somewhat tipsy after some five, or six hours of sleep. Damn girl you overdid it, and on a weeknight, no less. As my attention shifts from my cock to my clock I can see I already missed my first class. Mon Dieu!

Sitting up in bed I groggily wipe the sleep from my eyes with some man’s blue dress shirt, unbuttoned and haphazardly draped over my breasts as a makeshift nightie. Pushing the covers aside it’s evident I’m wearing nothing else, though, panties rarely survive an overnight stay on me, or otherwise. I note a familiar starch-like residue flaking off the blue cotton as I begin to half-stumble across my pigsty of a bedroom. At full mast my exposed girl-cock curves upward toward the heavens on its own volition, freely dancing back and forth as I maneuver passed books, clothes, and other obstacles on my way to the adjoining bathroom. Stifling a yawn with the back of my forearm I’m beyond caring how silly I probably look as I position myself in front of the toilet to address the situation preventing me from releasing my cargo of craft beer, hotel minibar cocktails, and I forget what else.

In times like these I question whether all this has been worth it, but I know exactly who’s to blame for weaponizing my clit into something that’s, well, usually much more fun! And for me being a tad taller, my tits being a little fuller, and a couple other things. Nevertheless, the face responsible for getting me into these situations came stock equipped from my mom and biological father. Though it has caused some trouble in the past, I’m not ashamed of my body; far from it. This was all of my choosing, and right now I’m choosing to beat off like a champ so my cock will go down enough to let me pee. Seriously, the trials life can throw at you sometimes.Mentally preparing for my first task of the day, I’m caught in a moment of déjà vu, reminding me of past incidents. My aim sucks, at least when doing that, and I’m tired of always cleaning up after myself. But I’m out of condoms again, and screw it. This is an emergency, or at least it sure as hell feels like it! My normally flat tummy is visibly bloated with fluids screaming for freedom. Not to worry though, I can cum pretty fast when I set my mind to it, and it doesn't hurt that I woke up already cocked, loaded, and dripping like a leaky faucet.

Grabbing the tip of my girlhood with my right hand, my long fingers can only just wrap around as I coax a few drops of clear precum. A shiver shoots up my spine as I deftly use my fingertips and then my palm to swirl over the exposed glans at the end of my uncircumcised shaft, covering me in goose bumps and hardening my nipples against his shirt. Over the years, in her aroused state she’s grown nearly as thick as my wrists at either end, even thicker t
