Pulling the Strings

The accomplishments and accolades that sixteen years had awarded to Jack Kurst made words like "brilliant" and "genius" seem trite in comparison. A prodigy of sciences and mathematics, nearly every field of study had been mastered before the age of ten, so much so that new ones had to be created and recognized to properly acknowledge his enlightenment. By his tenth birthday, solving Cold Fusion was a fond memory, and by his fourteenth, he'd completed the most ambitious undertaking in medical history; fully functional biological molecular nanites, small enough, yet powerful and fast enough to completely rewrite a person's DNA, and reshape molecules and atomic clusters, within a living human being, with no negative repercussions. The nanites were his greatest achievement thus far, and the first step in an ambitious, life-long plan to reshape the entire world into one of his design. However, as with all things, greatness had its price, and Jack's life was one of intellectual isolation. His father, James Kurst, had died in a horrific freak accident in his laboratory, leaving the man's body mutilated beyond recognition, and robbing Jack of the only man who came close to matching his intellectual prowess.

This left Elizabeth, Jack's mother, a widow, a pregnant one at that. From that point life was not kind to poor Lizzy and her , her son started suffering serious headaches that often woke him up at night, screaming in pain. After her daughter Katelyn was born she went into sever postpartum depression. Which only worsened when Katy started developing serious learning disabilities. The suffering of himself and his family were his original motivation to develop his nanites. At least until puberty hit.

Afterward, Jack's motivations were far from puree. He was a very smart boy after all, and a high degree of intelligence, also lead to quite an imagination. Combine that with teenage hormones and it lead to a very deviant sexuality. The first alterations he made were to himself, outside fixing his migraine problem, he also 'improved' himself. He kept his scruffy blond hair, and green eyes, as well as his scrawny build, but made his muscles more toned and wiry, as well as greatly.. enlarging a certain part of his anatomy. His family's memory was tweaked slightly so that they always remembered him being 'big' down there. The nanites in his system were the master control version he made specifically for himself, allowing him complete control of not only the nanites in his body, but the ones in his mother and sister.

His primary victim was his mother. Elizabeth was a fairly demure woman before Jack started in on her. A devoted mother, and a hard office worker. After loosing her husband, she ceased to even try dating again, convinced that she was too old and unattractive to even try. Shy and rather straight laced over all. She was not an unattractive woman, decent height, and rather plush with nice large breasts, though time and gravity were starting to take their tole. Her vivid red hair and beautiful green eyes tended to draw attention but she never seemed to notice.

That all changed after Jack's nanites started doing their work. Over the course of two years Elizabeth was completely changed, both physically and mentally. Gone was the almost suicidally depressed middle aged suburban mom, to be replaced over time by a lewd, crude, foul mouthed dominant slut. She was still a loving mother but cursed freely, and always got what she wanted, especially from men. Not that she slept around though, as no man could measure up to her standards, especially not the beta males at work. There she ruled the office, the men wanted her, and the women were both jealous and respectful.

All this was largely due to the physical changes she underwent. Her body matched her new attitude. Large and in charge. She'd grown to a rather intimidating six feet ta;l, and rather broad at that. Her vivid red hair remained, as did her green eyes and soft motherly face, however, she now possessed the body of a weight lifting fertility goddess.

Her shoulders were broad and strong as were her arms, however no one could confuse her for anything but a woman, not with the huge gravity defying M cup breasts hanging from her chest, each cupped with a nipple nearly the size of her fist when aroused, and aureola as broad as her palm. She also possessed a bit of a paunch, but upon closer inspection it was clear that the curve of her stomach, was indeed thick layered muscle, akin to what one might find on a power lifter. Her hips swelled out obscenely as well, lusciously wide and screaming fertility.

Her thighs were soft and well padded, which only concealed their power, easily able to crush a watermelon between them. What actually lay between them might be the biggest most succulent pussy on the planet, as far as Jack was concerned. Her plump mons formed a pronounced mound that curved from her loins, framed by thick full pouty lips, and a clit easily as large as one's thumb. It was well cared for with a thick but well trimmed thatch of dark pubic hair just above her pussy. That big juicy cunt was also so very messy, prone to pouring juices down Lizzy's thighs the moment she even got slightly aroused, and the hot feminine scent that wafted from her muff could drive men to distraction, as it so often did at the office.

Elizabeth's most distinctive feature however was likely her absolutely gigantic ass, each of those twin globes were perfectly rounded and soft, without a sign of sag or cellulite. That prodigious posterior was easily over seventy inches wide, and bounced wonderfully with every motion she made. Hidden between those huge buns was hidden a big puffy pucker, that was clearly regularly trodden by any number of Elizabeth's rather broad collection of sex toys.

The only reason she relied on such things at this point was because no man could measure up to her rather lofty standards. She was a big woman and needed a -big- man. It was just a pity that the only man that measured up was her own son. However that distinction mattered less and less to Elizabeth as time went on. She was a woman with needs, and her boy's big bulge was looking more tempting by the day. Partly due to the fact that Jack had gone so far as to instill his mother with a latent incest fetish, that was starting to come to the fore.

Comparatively Jack's sister Katelyn had little done to her by the nanites. Her learning disabilities had been cured, and everything brought within normal levels for a child her age. He did instill in the girl a certain amount of sexual 'curiosity' that would no doubt come into play soon. Certain parts of Kate's anatomy were matured well beyond her five years. No breasts to speak of but her little nipples could get nice and puffy at times, and her little muff was a bit plush and full for a girl her age. It would be ready to be put to use when the time came.

Chapter 1: An average day.

It'd been an interesting two years for Jack, that was sure. He played the typical shy bookish boy, even as he schemed and observed. As he headed down for breakfast, he could feel his mother's hungry eyes upon him, as he made his way downstairs in his typical morning attire of a simple t-shirt and his obscenely bulging boxers. He could feel Elizabeth's eyes practically burning through his boxers, and smiled inwardly. He doubted his mother could hold herself back for much longer.

"Morning boy, what did I tell you about getting dressed? Its almost time for school." the large woman said with a wicked grin, that told the truth, she enjoyed seeing Jack like this. He of course simply chuckles and walks over to the kitchen table to sit. "I am dressed mom. It'll only take a minute to throw some pants on before the bus arrives." His mother simply snorts. "Don't get smart with me boy." was her only response.

The youngest of the family, Katelyn watches from across the table, slightly confused. She was very curious though, and often snuck shy glances at his brothers big bulge as well. Jack had increased her libido beyond what a girl that age should be, and increased her sexual curiosity, but he'd doubted the girl had even started masturbating yet, even after the changes. That would be changing soon.

Jack smiled inwardly, as his mothers huge breasts pressed briefly against his back as the large woman rested a plate of bacon and eggs in front of him. "Eat up boy, you're gonna need your strength." the woman whispered rather suggestively in his ear. The teenager shivered inwardly and felt his package press uncomfortably against the underside of the table. His other did so love teasing him, but he continued to play innocent. "Thanks mom, I got a bunch of tests today at school." which were trivial to him but he kept his grades at only a somewhat above average level.

A few minutes later they were all done eating and Jack pushed away from the table, his boxers still somewhat tented after his mothers previous tease. Both ladies notice right away, his mother almost growls in want, it was a low soft sound that Jack only heard thanks to his enhanced senses. His little sister Katelyn glances were more curious than anything. Standing he stretches and gives his mother one last teasing show before he trots upstairs, but not before his mother gives him a playful pat on the ass in passing.

The rest of the day passed rather typically, Jack got on the bus and went to school. Once there, as he often did, he partitioned his mind like a computer's memory, using just enough brain power to get through school and pass all his tests with a few intentionally incorrect answer, while the larger part of his mind plotted about the future, and thought about all the things he was going to do with his mother and little sister.

As boring as school could be at times however, it was nice to spend some time with his best friend Rose, and his favorite teacher. Both of whom he'd no doubt be having fun with in the future. His only real problem at school was one of the football players, Butch, who styled himself as a stereotypical bully, but that was also a problem that would be dealt with in time. The day passed relatively quickly, and soon he was on his way home.

As usual Jack was the first one back, his mother would be getting home from work soon and would pick Katelyn up from day care along the way. So for now Jack was alone, and made his way into the basement where his 'lab' was kept. It was just a front, a few computers and a chemistry set, his mother indulging his scientific 'hobby'. His real 'lab' was hidden, accessible through a disguised elevator in the floor using a pass code only he knew. Tapping it into a nearby keyboard, the floor under him started to descend into his real lab. It was a complex he started excavating over two years ago, using an earlier simpler version of his nanites. The materials in the earth were re purposed, used in nano fabricators to create the equipment he needed. Power was a non issue as well, he'd perfected cold fusion by the time he was ten. His mother would be home soon so he didn't linger long, only stopping in to check a few readings and make sure all was running as it should before heading back up into the basement to do his homework. Which took all of two minutes. He was done by the time his mother got home and went back upstairs to greet her. Of course his little sister was with her,

"Welcome home ladies." Jack says with a boyish grin and walks over to give his little sister a hug, which she returns with innocent affection. He embraces his mother as well, and quickly finds his face shoved in her cleavage, while her nails run down his back. Through the nanites he could sense his mother's hunger, and how she repressed the desire to shove her tongue down his throat. He chuckled inwardly and freed his face to kiss his mother's cheek before stepping back. She was still resisting, only a hint of her previous morals remained, having been eroded over the years.

"Thanks boy." Lizzy whispers huskily before letting her son go, eyeing his big bulge for a moment, which had swollen slightly after that hug.

Jack smiles and walks off and heads into the kitchen to start working on dinner. His mother worked all day so he often made dinner to give the woman a break. Lizzy had become the queen of her office space, people had noticed the changes alright, but they were gradual enough that everyone thought she'd been working out or something. She was still restrained with her children, but at work was another story. She wasn't afraid to flaunt her sexuality, and every man in the office lusted for her, and she had them all wound around her finger. The ladies were too intimidated to do anything about it. She kept everyone working productively though. All it took was a whisper in a man's ear and they'd trip over themselves to do anything she wanted, and her motherly nature made all the ladies look up to her, even if they were a little jealous. At home Lizzy could relax but still held back, simmering in the desire to pin her son down and ride him all night long. By the time dinner was served she was stewing between her thighs and would need a long shower before bed.

Jack had done little to encourage his mother after altering her mind and body, he'd never outright forced her to lust after him, or mentally compelled her to want to fuck him. He'd simply given her an incest fetish and a taste for huge cocks. Everything else was on her, and he was happy to see everything was going according to plan.
