It was called Perpetual Puberty Syndrome - PPS for short. No one knew if it was truly some sort of virus, a parasite, or even something mystical; considering the effects it had on the female human body. Nothing adhering to the laws of biology, psychology and physical science could keep someone that hydrated, that active and that mobile in the way it twisted a person to their very core. Only women were at risk, almost any age, but it seemed to target those that were lacking personal assets of almost any young age. Especially those that desired to grow up, to be bigger. They would certainly have that and much more than they could possibly want.
The effects start out with only a tingle here and there in the victim’s possibly soon-to-be-developed erogenous zones; mainly at the nipples and the clitoris. From there, inflammation and growth slowly begins to start as the body very slowly, but slightly visibly begins to age. The process will soon continue into pulsing spurts of pleasure and growth, until the body becomes whatever age that person would be as peak sexual maturity, fertility and physical fitness; this is what’s known as the beginning “Aging Stage”.
What then follows is the body taking some form of metabolic break as the growth seems to stop… when in reality, it’s only slowed down just in time to begin the next phase: the “Overgrowth Phase”. To put this stage as simply as possible: think of all the bodily changes that goes into a girl aging to their prime, then make those changes continue more and more. Hair grows longer - often sprouting in areas associated with puberty, like the pubic area and sometimes under the arms. Some reports state that victims can have hair from their scalp grow as long, or sometimes longer than they are tall - no matter how high that number gets. Breast tissue and mammary glands begin to develop - the problematic part is that they follow a sort of hypertrophy-style growth where said breasts have way more mass and way more engorged milk glands than any normal female. The fatty tissue in the rear area of the body also significantly swells, as if in a fierce competition with mammary growth. Subjects have been reported to bend over and sway their enlarged jiggling buttocks in the direction of potential mates, as if presenting like a wild animal. The only limit on this drastic hourglass of hypertrophy seems to be that the growth of breasts or buttocks can never reach proportions where the body would be either too severely hindered, or even downright immobile; though there have been some exceptions. Nipples also start developing rapidly, growing longer and thicker than most humans, with the areola region also bulging and widening from the constantly developing fatty tissue. Lactation starts rather early in this stage, the bounty of milk seems to come from seemingly nowhere, but consuming sustenance of any kind seems to stimulate production at an alarming amount. Hips also begin to widen considerably, as well as thigh girth and leg length; almost as if the infected is evolving to be the ideal fertile human, even as impregnation by any means seems to be impossible in any stage. As the subject’s pussy begins to grow more sensitive, it often sprouts pubic hair as it begins to engorge around the outer labia, as well as the clitoris - which can reach sizes comparable to a pseudo-phallus. The aroused subject also begins to secrete sexual fluids in a rather alarming and gradual rate; starting out as moisture and dripping – like most aroused women, then developing into large amounts with a reported sweet and honey-like taste. The combined fountaining effects of lactation and vaginal juice secretion never seems to cause the subject any symptoms of dehydration; which only furthers the supernatural evidence of this being some kind of otherworldly cause.
As if to compensate for later stages, the body also begins to experience a rapid development of muscle growth. Depending on the subject, this can be just an athletic build, or all the way up to a professional bodybuilder, yet always with none of the usual side effects of decreased fatty tissues. Lastly and the most significant is the subject’s overall height. Once the overgrowth stage starts, subjects start to spurt taller than the average human. The increase in mass seems to come from nowhere, or at least in no comparison to the amount of mass gained from food. No known limit to this stage’s height has been recorded, as keeping subjects without causing them harm has proven to be rather problematic.
The psychological state of an infected seems to start out in various stages. If the infected is prepubescent, the subject starts out with a reported unfamiliar tingling as they age to sexual maturity. Then as the brain seems to develop more and become more susceptible to the constant feed of potent hormones, the subject’s libido begins to rise in a constant incline. Starting out as just a mild arousal, then an increased level of horniness, with the urge to stimulate pleasure growing worse and worse, no matter how many orgasms are reached. One could compare it to the symptoms of estrus often experienced by certain animals. The pheromones of an infected in the overgrowth phase become more and more potent, with some later stages appearing as a semi-visible pink fog. Subjects of any gender attracted to females will experience extreme arousal with an almost zombie-like state caused by some of the larger subjects. If any suitable males or females are nearby, the subject will not hesitate to subdue and attempt to mate with them, despite any previous sexual inexperience. If no mates are available for a long period of time after the overgrowth stage, the subject will resort to masturbation. First by means of their hands and fingers, but possibly due to the overgrowth of their vaginas, or some other carnal need, they will seek stimulation from any available, safe and somewhat clean object. Though as far as the risk of internal damage from rough object masturbation, the tissue during the overgrowth phase seems to be in a constant state of regeneration, to where no form of damage or flesh wounds have ever been recorded, nor any signs of experiencing pain. Implemented objects can range from the corners of tables, phones, sex toys, pens, bottles, the handles of tools. Even in the later hyper stages: parking bollards, fire hydrants, lamp posts, even vehicles are suitable “toys” for infected. Some reports involve men that were taken advantage of and roughly made to perform intercourse until the size of their personal assets no longer pleased their larger mates, before they moved on to larger prey. Or even in larger cases where a person’s whole body can be used to satisfy a large enough subject.
The following is an excerpt from observing a purposely and unknowingly infected prepubescent female, just before the subject violently burst from their house and went on a rampage in her local city:
Subject started around four feet tall with short red hair, blue eyes and a rather unremarkable build in both musculature and dress sizes. Age, location and identity have been redacted for the sake of the project.
She first started out acting as perfectly normal. Only known exception was the rather large midnight snack she raided from the downstairs fridge, as well as the fact that the subject vocally and rather melancholically lamented that she wished she wasn’t such a runt. That she could be a grownup and has a nice hot body like her mother and siblings.
Aging Stage began during the girl’s sleep, she seemed to be having some sort of dream as her body began to perspire from the initial growth. The extra-large t-shirt she wore covered most of her body down to the knees, aside from a pair of panties that were slowly becoming tighter and tighter. By the time the subject awoke, she was missing the baby fat in her face from aging to a teenager. The telltale tingling started in her chest and between her slowly thickening thighs as the first dew of arousal began to form. As if on instinct, the girl’s hands went to both her crotch and chest, finding quickly that her chest was indeed growing larger. The reaction to such was a mixed state of shock, then joy of her supposed wish coming true. She ran over to her full-body mirror, watching as her body inched taller and taller. At the start, the waist of her shirt came up to her knees, but was soon only reaching mid-thigh, then up to her crotch, just as her hips began to widen. Lips began to fill out as cheekbones morphed her face into a more mature state. As arousal began to drip from her now developed and exposed pussy, her panties mercifully snapped.
While this was going on, her budding breasts formed two growing tents in the white cotton fabric, capped by two thumb-sized nubs that were her nipples. She was full-on groping them by the time they reached the size of her head, bringing her to her first orgasm. Getting to her feet again, her infection gave her only a few precious minutes to admire her rather normally-large adult body, thinking this was the end. She only started realizing something was amiss when the top of her head began to be cut off from her reflection. Another factor was the strange white droplets escaping from throbbing engorged nipples, while the inside of her calves were feeling her juices start to drip down from her hungry snatch. A patch of red pubic hair sprouted in a small bottlecap-sized areola before spreading wider and further down her plump wet pussy lips.
Subject contemplated whether to go downstairs for help, or giving in to her desires – the latter almost always is the case; especially when the subject has a clear reflective view of their changes. It started at first with her simply inserting a finger while her other hand teased her nipples. This rewarded her with a gush of milk from her developing breasts, which she eventually found the bust size and flexibility to fit one of her puffy nipples between her swollen lips and taking a long sensual suck. The fact that she retreated to her bed gave a good scale of her growth, evident by her legs creeping across the creaking mattress. Soon he heels bumped against and then passed the bedframe, followed in sensual spurts by her calves and back of her knees. The only thing that snapped her momentarily out of her frenzy of milking herself with one hand and stimulating her plump pussy lips with the other was the impact of her head to the wall behind her. Her shoulders and upper back having to pass that first. She tried her best to stumble to her feet, almost slipping on a self-made puddle as she ran a hand across her growing red landscape of a bush, as wide as her palm and surprisingly silky smooth. Pinching her now gumball-sized clit almost made her convulse back into a frenzy, if not for her fear of breaking the house with her continued growth. Though unfortunately, her journey was tragically cut short from another sudden bump to the head. This time into the very ceiling of her room. This caused a chain reaction of her falling on her ass and labia, which sent her just enough pleasure to begin the chain of masturbation and growth anew.
Finding not a single big throbbing cock in sight, she resorted to fingering herself with both hands as she sat bucking in a growing pile of her juices and milk in the middle of her room again, as her whole body dripped with sweat, along with traces of saliva from the corners of her mouth that fell down to her gurgling chest. Being forced into a sitting position because of her climbing height that would make her damage the ceiling when standing up…but every pulse of growth and pleasure would slowly bridge the gap once more. Hair cascaded down her body like a red follicle-waterfall and bunching behind an ass that a person could sit on like a pair of beanbag chairs, but still incredibly firm. Her musculature pulsated and swelled, feeling like she was being pumped with liquid lead from her evolving body growing dense enough so that she didn’t collapse under her own weight. Her budding abdominals like a half-dozen set of boulders grafted under her still silky-smooth skin and resting in the shadow of her enormous bust like the trunk of a mighty tree. This growth made her rather sizable melon-sized biceps press into the sides of her sensitive breasts, while her thighs felt thick and hard enough to crush a boulder between them - oh how she wanted to test that out! Even her shoulders had broadened into hulking wide deltoids that rounded out like cannonballs. Her vision became more and more obscured by her own boobs as her long teat-like nipples kept sputtering out milk from every overworked duct with every wince and pulse of her body. She soon realized that her clit she had been rubbing with her thumbs was now bigger than those two digits combined, growing and throbbing thicker every minute. All while her face-wide vulva greedily sucked at her eight other fingers and was more and more giving her a grim fact that she would need to address before she went mad with desire… this was not enough.
A frenzy of pleasure continued as the girl groaned, stomping over to her bedpost and taking the big round smooth wooden tip at the end and easing it into her dripping lower maw. The very foundation of her room began to creak as she squatted over her prize and began thrusting and bucking.
Once she spurted big enough to break out of her house, she quickly made her way through the neighborhood, quickly finding the family’s sedan and sliding it in fender-first into her growing self. The convulsions of her muscled pussy actually crushing the metal. No signs of pain or damage to her body occurred as she removed the crushed toy. Her next prize was a neighbor’s house. She stuffed a whole fist into her greedy pussy in anticipation as she made her way to the roof. Her red-haired cunt rained juices down the whole building as she ground her redwood thighs against the angled roof. Her clit by this point was growing into an engorged spherical shape above her jungle of pubic hair. Soon causing the whole structure to collapse from a sudden convulsion-filled orgasm that raised her higher Even that wasn’t enough… she wanted something bigger… she wanted to BE bigger.
Her last known sighting before a citywide evacuation was instated was quite the sight to behold. A waterfall of clear cum cascaded down between her gargantuan thighs, accompanied by twin arcing waterfalls of white creamy milk that began to flood the city streets she rampaged through. Lips as thick as thumbs lining her face with a dull expression of pure intoxicated arousal. Breasts that were so massive that they stuck out several feet in front of her, while the cusps of her jiggling gushing masses of mammary were level with her waist. Nipples could be compared in proportion to thick German sausages, constantly twitching and fountaining milk atop bloated smooth areola the size and shape of cereal bowls. Her musculature as far as proportions in her arms and legs seemed to have stopped, though still thick enough to make any professional male bodybuilder intimidated – biceps and deltoids could be compared to a bit smaller then her head in terms of mass whenever she gave a flex. Her hips and ass were seemingly trying to compete with her breasts for sheer mass. So massively wide that she couldn’t walk down the city streets without scraping into building walls on both sides – yet her soft durable flesh could never be cut, never damaged in any way. The shelf of her ass could fit a person to each cheek, if she were still average adult height and not something that could rival a movie monster. Wild vibrant red locks cascaded behind her like a cape and dragged behind her for a few feet. Her push was so large and wild that it engulfed her head-wide labia with a bit of the still silky un-matted pubic jungle hanging down below, while above was a bit of a treasure trail up her rigid stomach, halfway towards her belly button. The clitoris that pierced the canopy was a bulging angry colony of nerves that was actually taking on a more ovular shape as it had reached about as large as a lemon.
Miles away from the evacuated city, pass the spreading flood of milk and juices, you can still see her off in the distance straddling a building, easing herself down on it and roaring with pleasure as she rides it until its collapse. This was usually met with groans of frustration – sometimes taking it out on other structures with her immense strength, before calming herself down with some more self-nursing and moving on to her next quarry. What worries us is that she’s taken to leering the far-off mountain in the distance, licking her lips in anticipation.
