Since she was a child Jean had always loved flying. Though it was over twenty years ago she could still remember the first time when she had entered a plane. She was so nervous she had hold tightly to the arm of her mother the entire time on the airport, and once they sat inside immediately grabbed the leans of her seat. When the plane took off she almost screamed, and couldn't calm down until the signs for the seatbelts had gone off. But as she dared a look outside the window after a while and stared at the sea of white fluffy clouds and the beautiful landscape beneath the plane all her fear was immediately replaced with utter awe. The world below her was looking like a playroom for kids, and all the cities, fields and mountains were toys. Since that moment she loved flying, and even right then as an adult woman looking at the cotton ball-like clouds beneath her brought a smile into Jean's face.
Although it still felt a little awkward not to fly inside a plane, but with the help of hover implants inside her feet and hands.
Spreading her arms from her body Jean floated through the sky, far above the clouds. Invisible flames were emitted through the skin of her hands and feet, keeping her body in the air while making her fly at an incredible fast speed. A part of her left pupil had turned from its natural gray colour to red, displaying various information to Jean at the inside of her eye, from her current altitude and the temperature around to how far away she was from her destination. A small "pop-up" in form of a red arrow informed her she had to change directions. She tilted her left hand a little, flying a small curve until the arrow turned green and disappeared. The distance-meter told her she was 400 km away from her destination, tendency sinking. Jean sighed, feeling as her stomach began to turn – she wasn't really eager to arrive at her destination. A few seconds later the display only read a hundred kilometers, so she began to drop her speed. When the distance fell below a kilometer Jean pulled her legs towards her belly, before moving her body in a straight position. Just as the display hit zero she stopped in mid-air, standing in the sky with all of her hover implants pointing towards the ground. The parameters for speed and distance were replaced with the current air pressure and humidity.
Jean took in a deep breath, wishing she could just turn around and leave this place as fast as possible. Instead however she lowered the power at which her hover implants were working, and in a rather fast pace began to sink towards the ground. The display for altitude was steadily falling while the air pressure rose. Her bare feet soon sunk into the clouds, and shortly after the rest of her body followed. As she moved through the clouds her long azure hair became a little wet, as well as her clothes. She activated the heating system inside her cells, setting her body temperature over a hundred degree Celsius. The water quickly evaporated and mixed as steam into the clouds again, leaving her dry as a bone. Once she was through she could see a small town beneath her. The machines inside her skin cells that had protected her from the low air pressure deactivated as she approached the ground, while her camouflage system activated – people didn't need to know a gynoid was about to land in their neighborhood. The fields and forests around the town faded out of her sight as Jean sunk lower, heading for a specific house.
An inch above the ground she deactivated her hover implants, softly landing on the lawn of a small house. Her left eye turned grey again as Jean shut off the display, while at the same time she reactivated her temperature nerves. A sudden heat wave quickly reminded her to deactivate the heating system as well, while at the same time she decreased the sensitivity of her pain nerves. "I hope the professor has an upgrade for my temperature systems today", she mumbled before switching off her camouflage and setting all systems back to standard. Like any normal person (putting aside she wore no shoes) Jean walked over to the house, the grass tickling her bare feet a little. Instead of going to the front door however she marched straight to the cellar door a few feet next to it.
A small scanner was built into the wall next to the entrance. Jean first put her hand on it, waiting for the machine to identify her finger prints, before holding her face in front of the screen so it could analyse her facial structure. "ACCESS DENIED", a robotic voice told her. Putting her hands on her hips Jean glared at the machine. She tried two more times, but the result was the same. "Very funny, professor", Jean murmured, knowing how he wanted her to get in. She took a look around to make sure nobody watched her. Even as she activated her X-ray vision she couldn't see anyone, but decided to double-checked scanning the environment for life-forms. No driving car in a hundred meter radius, no curious neighbors around, only a squirrel was sitting on a tree behind her. Again Jean sighed before she positioned herself in front of the house. She bent down to her knees, grabbing the bottom of the wall.
The whole house shook and trembled, some rubber falling off as Jean slowly lifted it into the air. Her face didn't show any signs of effort as she raised the whole building above her head, cautious that the furniture inside wouldn't slide out of place. Below her she could see the staircase to the basement – and the entire basement – right behind the door that wouldn't let her in. Activating the hover implants in her feet she set off a little from the ground, lifting the house even higher into the air, and placed herself above the stairs. She moved the house a little to the side so it would be at the same place as before, before she began to sink down again. There was nearly no sound as the house landed back on the ground, putting everything around Jean into complete darkness since there was no light in the staircase. With her night vision she could see the door at the end of the stairs was right open. She dropped herself to the ground, took in another deep breath, and then finally walked through the door into the basement.
Inside one could have thought be in a horror movie from the early 20th century. The place was crowded with weird machines, some larger than an elephant, others tiny and fragile. Test tubes were standing on the numerous tables scattered throughout the cramped laboratory, while cupboards filled with blueprints and more machines formed a maze most people would forever get lost inside. From time to time a lightning went from one machine to another, and some of the colourful chemicals inside the test tubes boiled and blubbered even though they were not heated by anything. "Professor?", Jean called into the room. "Professor, are you here?" She was about to activate her X-ray vision again when she heard some noise coming from the back of the room. Behind a cupboard filled with god-knew-what a middle-aged man in a laboratory coat appeared. His short brown hair was a little messy, and he seemed to be in desperate need for a shave.
"Ah, Jean", he greeted the gynoid, smiling as he cleaned his oil-drenched hands with a handkerchief. "Welcome to my little realm! Came for an upgrade, huh?"
Jean smiled back, though only out of politeness. "Yep!", she replied, taking a step into the laboratory. "Today it's only software, right?"
The professor nodded. "Just fixing a few minor bugs and updating some programs."
"Ah, great!", she said with faked joy. "I have to watch YouTube videos on my PC at home because the flash player in my system isn't up to date. By the way can't you just make it so I'm able to download such stuff myself?", she asked a bit hopeful.
"It's possible, but it would make you vulnerable to viruses and hackers", he answered, smashing all of Jean's hopes to spare herself at least some trips to this place. "And I doubt you want anyone to mess with your body – anyone but me, of course." The smile on the professor's face crept Jean out. She followed him to the back of the laboratory, past numerous cupboards and tables filled with gadgets and chemicals. Some of the machines Jean already knew or could at least roughly guess what they were meant for, while others were completely alien to her. While she stared at the science surrounding her Jean almost bumped into the professor as he suddenly stopped. "If you are interested though", he said with a smirk "I also have a new piece of hardware for you."
Jean crossed her arms before her chest. "Oh great, just what I need", she said, dropping all of her fake friendliness. "Another piece of metal junk inside my body."
The professor grunted. "You know that without this metal junk, you would be lying six feet deep under the earth right now", he reminded her. "A little bit more gratitude would be appropriate, don't you think?"
Jean rolled her eyes. "Oh yeah, you are really generous to have transformed my body into a biomechanical sci-fi-monstrosity", she said sarcastically. "And I can't thank you enough for forcing me into a contract that makes me your personal guinea pig for the rest of my life!"
"Come on, one experiment per month is a fair price for saving your life!"
Jean turned around, showing her back to the professor. "I wonder", she mumbled, more to herself than to him. "Sometimes I wish to have just died back then. I know I'm practically a super-woman with a virtually indestructible body that won't age or get sick, and I can't deny a part of me likes it, but…" Jean looked at her hands. They seemed completely normal, like those of any other person. Still, she knew beneath the artificial skin there were hover implants, titan-joints, a musculature made out of biomechanical tissue and whatever other stuff the professor had put into them. "My own body feels completely alien to me! I'm more a machine than a human! I… I…" She clenched her fists. "I feel like a total freak! A monster!"
The professor shook his head. "Now calm down", he said, sounding as monotone and disinterested as the card-reader. "It's not like you are the only gynoid in the world."
"Yeah, cause five is such a high number", she said, turning around again. "Practically run into one every day."
Again the professor smiled. "Well, since you can travel at over a hundred kilometer per second it would be no problem." The way Jean glared at him however told the professor she was not amused, so he quickly changed the topic. "But seriously, I actually don't have any new components for you. I just want to test out a new formula."
"Then what was that about the hardware?", Jean asked. She could see the professor was holding back another grin.
"You'll see once we get started. So?"
Knowing the professor Jean had a very bad feeling about this. Then again, she was forced to "assist" him in at least one experiment per month, or else she would get into trouble with the law. And she remembered very well the last time when the end of the month had come and he had no experiment for her – and what he eventually came up with…
"All right", she sighed, already regretting her decision. "Go ahead and put your poison into me."
The professor couldn't hold back his smile anymore, showing he also needed to brush his teeth. He gestured with his hand towards a metal table that looked like Frankenstein had used it or his monster. "Sit down", he told her. "You know the procedure." All too well, Jean thought as she sat on the table. Next to her a black short-sleeved top was lying, looking like it was made out of rubber. "All right, take off your shirt and put this on", the professor said while walking over to one of his machines. Jean clenched her teeth, but pulled her top over her head to reveal her slender waist and a white sports bra. She grabbed the shirt, finding it also felt like rubber (though she was quite confident it wasn't) and began to slip into the sleeves. "Bra off, too!", the professor called over. Jean stopped, throwing an angry glance at him. "Come on, it's not like I haven't seen you naked before! I even have pictures lying around somewhere."
At first Jean didn't react. Looking sternly at the professor she put the shirt back down, before placing her hands behind her back. With a small click the lock of her brassier opened, falling on her lap to reveal a pair of tiny, nearly invisible breasts. Without a word she slipped into the "rubber"-shirt, ignoring the lecherous stares of the professor. "Watch out or your eyes will pop out", she warned him while pulling the fabric past her belly. The top was lying almost skin-tight on her body, showing all of the few curves she possessed. She noticed there were a few holes in the fabric, right at her waist. "You really are exploiting your position, aren't you?"
After looking at Jean in her extremely tight top for a while the professor walked over to her side. "Don't complain to me that androids have fewer rights than normal humans", he told her. "But yeah, I am." As Jean lay down on the table the professor pulled out some wires and hoses from beneath it. While he sorted them in his hands Jean lifted her head a little to see where they were going. The wires seemed to be connected to the machine the professor had been working on before, while the hoses ended at several large glass tubes at the wall. They must have contained at least twenty liters of different coloured chemicals inside them, from boiling red chemicals to blue blubbering ones – and Jean had no doubt they all would soon be inside her body. "You think there is even enough space inside me for this?", Jean joked.
The professor chuckled.
Jean then felt as he held the wires at her neck. As the metal tips touched her skin a few holes automatically appeared inside it, into which the professor stuck the wires. After she was connected to the machine he attached the hoses in a similar way through the holes in her shirt, where they also automatically connected to her body. Once everything was in place the professor went back to the computer desk at the machine. "So what is it today?", Jean asked as the professor typed something into his keyboard. "Some new medicine that's too dangerous to try out on normal humans? A hormone therapy? A love potion?" Jean glanced at the professor. Never had she seen him grinning that much before.
"A mixture of all, if you like", he replied. "It's a surprise." Jean hated surprises, especially those of the professor – the last one had turned her hair blue. While the professor typed into his machine Jean tapped with her fingers on the metal plate, feeling as sweat formed on her forehead. "All right", she could finally hear the professor say "Here we go!"
A small electric pulse went through Jean. Staring at the ceiling she could hear some weird noises as the tubes started pumping the liquids through the hoses. A few seconds later the chemicals flowed into her body. Her biomechanical heart was racing as they worked their way into her veins, making her waggle uncomfortably on the table. Already wishing never to have agreed to this she wanted to shut down all her systems and fall into a temporary stasis. But to her shock she found that most of her functions were locked, leaving her with barely any control over herself.
"Sorry", the professor said, noticing Jean's efforts. "But for this experiment you need to be at full conscience, so I blocked your systems." Jean wanted to say something, but the words got stuck in her throat. A numb feeling settled into her body, making it tingle all over. Closing her eyes she put her head back, breathing through her mouth as if she didn't get enough air. "Metabolism stable", she could hear the professor talk to himself. "A bit too stable - she should be in a way worse shape. Double the dosage!" At her side Jean felt as the liquids flowed faster into her, strengthening the prickle in her body. Feeling ever more uncomfortable she arched her back, pressing her shoulders into the table. "Flow of blood accelerates, higher amounts of adrenaline are thrown out, body temperature rising – now that's more like it! Next, I'll inject the formula."
Turning her head Jean realized one of the hoses was still empty. The professor pulled a small lever, sending a purple liquid sloshing towards Jean. The moment it entered her body she immediately felt a small burn in her side. The feeling grew stronger, heating her whole body up until she felt like she was taking a hot bath – a slightly too hot bath. "H-hey, professor!", she shouted with shaking voice. "C-can I at least d-deactivate my t-t-temperature n-nerves?"
"No dice. Now get ready, it's about to start."
Before Jean could ask what was starting a strong sensation went through her body. Cringing in pain she could feel the tingle was intensifying in her chest, as if all the chemicals were mixing together inside it. She leaned her head slightly forward, as far as she could, and closely watched for any kind of changes on her chest. The rubbery fabric was lying mainly flat on her torso, only bulging slightly from her small breasts. The sensation grew stronger, but she couldn't detect anything weird yet. She wanted to scan herself to find out what was happening to her, but even that function was blocked. As she stared at her tingling chest, wondering what the professor had prepared for her this time, her usually flat nipples suddenly poked through her shirt. Jean blinked, watching as her breast-warts grew into small peaks. Before her very eyes then the tiny breasts inside her shirt suddenly began to rise up, swelling like a giant bee had stung her. "W- what…?", she stuttered. Wide-eyed she watched as the flesh around her breast-warts slowly ascended, sprouting from her torso like small plants. "What the…?!" Steadily her feminine curves spread out from her chest, growing into small humps. "W-WHAT ARE YOU DOING TO ME?", she finally screamed.
The professor busily typed around on his machine, occasionally throwing a glance at Jean's blooming bust. "What does it look like?", he asked back in a monotone voice. "I'm making your tits bigger."
Staring at her breasts in shock Jean watched as they pressed a growing dent into the already tight fabric. "Why?!", she screamed. Through the sound of stretching rubber Jean could hear the professor chuckle.
"Well that's funny. By now I have replaced your blood cells with nanobots, implanted electronic wires into your skin, messed around with pretty much all of your inner organs and forced you into some very embarrassing psychological experiments, but you never asked me why." Jean's breathing was getting faster, her swelling chest going up and down in fast spurts. "But if you've gotta know: This purple liquid is a formula that stimulates biomechanical hormone glands and forces them to work at 500% of their normal capacity… or 5000, don't have the exact numbers in my head. And just now, I stimulated the glands that are responsible for the growth of your breasts."
While her breasts conquered her previously plain chest the tingle inside them was growing stronger the more they pressed against her top. "W-why my breasts?!?", she asked hysterically. "Why can't you test it on my adrenaline glands or something else?"
"Cause I'm a sick man who sleeps with a Playboy under his pillow", the professor simply said.
Jean wanted to stand up and slap him across the face, but like her technical systems she couldn't control her legs and arms – she hadn't expected anything else, but it was worth the try. Meanwhile her bosom was rising like bread in an oven, tingling like her shirt was stuffed with feathers. At first the middle of her breasts was rising faster than the rest, giving them a slight cone-shape, but as time passed they gradually smoothed towards a round, hemi-spherical form. "Y-you have some kind of antidote for this?", Jean asked.
"That'll probably be the experiment next month", the professor replied. "Now concentrate, you'll have to fill out a questionnaire afterwards."
Jean had a ton of more things to say, most of them not suitable for minors. But the bigger her breasts became the less she found herself able to speak, until she could only bring out some dry coughs. Small prickles went through her biomechanical nerves as the fabric of her shirt stretched around her bulging chest. Her limbs were twitching as far as her paralysis allowed it, the sensation inside her growing stronger the smaller the gap between her breasts became. It felt like the tissue inside her breasts not only stretched her shirt but also the skin around them, making them more and more sensitive to every touch. Jean took in a deep breath, trying to breathe normally as she didn't want to show her arousal to the professor. On top of her swelling humps however she could feel as her small nipples grew a little thicker, standing proudly from her body.
"Looks like you're enjoying it", the professor remarked. Jean imagined him grinning from ear to ear, but was too "occupied" to glare at him. Sporting two fistfuls of breast flesh a chill went through her as the distance between her breasts shrunk to zero, making them slightly press against each other. While she fought down the sensations inside them her breasts shaped into a pair of small domes, pointing round and firm towards the ceiling. Their widest parts ascended from her torso as they flared over the sides of her body, gradually growing into full spheres. Jean was glad the fabric of her shirt seemed to be just as elastic as it looked like, allowing her to keep at least a shred of decency in this disgraceful situation. But although the rubber loudly stretched around her ballooning bust the space inside it was getting very small very quickly. Her assets squeezed against each other with growing force, increasing the prickles inside them. Feeling restless Jean wiggled with all body parts she was able to move on the table. She could feel every additional ounce of flesh inside her shirt as the fabric rubbed against her sensitive skin, making her nipples grow even harder.
Reaching the size of ripe oranges her breasts extended the hole for the head in her shirt, slowly pulling it towards her chest. The black fabric turned a little transparent as it thinned around her bosom, her areola starting to shine through. With more control over her body Jean would have probably waggled on the table like a fish outside of the water, but the most she could do right then was shake her belly a little. Her breasts responded to her movements, bouncing slightly from side to side. The space inside her shirt was cramped and narrow, but there was still enough room left for her breasts to bump against each other, each small impact sending a pulse of pleasure through Jean. The gynoid looked like she was about to jump up from the table, while her nipples poked painfully erected through her top.
"You're getting quite excited", she could hear the professor say. "Hm... We could do a little psychological experiment as well. Let's see what happens if I give you back the control over your arms." 'I'll break your nose wit them!', she wanted to yell at him, her breasts puffing to the size of grapefruits as the professor typed a few commands into his machines. A petite neckline was forming on top of her shirt, while at the same time the fabric began to slide over her belly, revealing a rising midriff. Her trembling arms suddenly moved wildly through the air as the stiff feeling that paralysed them vanished. Realising she had regained control over them Jean immediately spread her arms out from as far as she could, trying to stay calm. As her bosom reached further away from her however, boosting into lusciously larger and firmer forms, her arms slowly began to buckle towards them. Shaking as if she was about to freeze her hands slowly approached her rising breasts, while her fingers formed two cups in preparation to grope them. Jean panted heavily, and closed her eyes. Through the stretching fabric her light skin was slightly visible, her breasts reaching the diameter of CDs on their widest parts. Her head hole steadily moved up her bosom, revealing a growing amount of cleavage, while her shirt got pulled over her belly-button. Her hands were hovering only a few centimeters above her chest, the distance steadily decreasing as her arms sunk lower and her chest rose higher. Unable to resist any longer Jean gulped before poking the taut fabric with the tips of her fingers.
A soft moan echoed through the laboratory. Jean's whole body leaned up a little as waves of pleasure went through her, making her feel strangely relaxed all of a sudden. Carefully she let her hands fall on her chest, until they fully embraced her firm meat buns. Another moan slipped through her lips as she felt them swelling against her palms, growing so large they slumped down a little. Getting ever more to grab Jean's hands slightly pressed into her curvaceous flesh, stimulating her electronic nerves. Her legs shook violently, begging to break free of their stasis, but the only thing Jean could do was fasten the grip on her breasts. She wrapped the fabric around her fingers, stretching it further around her mammal melons. With clenched teeth she took in a deep breath, before her mouth broke open as she let out a long, sensual sigh. Her sounds of lust overturned the rubber as it ripped on top of her bosom, deepening the hole in her shirt and her small line of cleavage.
Tearing on her top her breasts grew to the size of her head, standing as two full lumps of meat from her body. Her bust was growing wider than her hips, being probably even visible from behind, while her breast warts were almost a foot away from the rest of her body. The top of her bosom reached to her neck, while the bottom arrived at her last rip. On each side the shape of her breasts was nearly perfectly curvy and stout, only her cleavage looking a little squeezed as there was only little room inside her tight top. Her shirt looked like it could explode any second, turning from black to gray due to the immense pressure. While the rift in her shirt steadily became deeper, her cleavage growing through the length of her fingers, Jean's hands softly fondled her bosom, luring moan after moan out of the gynoid. She tried to hold herself back, but the pleasure was so intense that she couldn't bring herself to stop. Two oval holes appeared on each side of her shirt as the tense fabric ripped there as well, allowing a small look at the edges of her firm curves. Being slightly released from their pressure her breasts jolted a bit forward, making small bounces into every direction. The outbreak made the rift in her head hole go up an inch higher, giving a generous insight to her cleavage. Bit by bit her swelling bosom stretched the tears in her shirt, leaving steadily more of feminine charms without cover. Her rising sweater meat was not the only thing that put the fabric under pressure though as Jean's groping also helped to reduce her top into nothingness. Every time she dug her hands into her firm flesh she felt her arousal shooting up a bit higher, which led her nipples to grow thicker and longer at each arousing impulse.
With a loud rip her breast warts tore two more holes into her shirt, standing like pink thimbles on top of her breasts. Slowly the fabric around her nipples slid over her areola, before wandering over her falling curves. Blooming to the size of big volley balls her breasts stretched the skin-tight fabric to the limit, pulling the shirt over her belly. Its short sleeves had been dragged over her shoulders as her breasts were almost consuming all the fabric. The holes around her nipples quickly got larger, growing from little golf holes to the size of CDs in a few seconds. Meanwhile the oval tears on the sides were also stretched around her rising bust, being roughly as big as Jean's hands. While her front cleavage had ripped through a third of her shirt, showing a wide and tight V-neck full of breast flesh, her shirt began to rise over her bosom, creating a firm under cleavage. Her top was near the point at which it showed more of her breasts than it could cover, but her last shreds of self-control allowed Jean to only grope herself at the regions where the fabric was still lying on her sensitive globes, though those "save places" were steadily shrinking. The best of course would have been if she had stopped fondling her bosom all together, but no matter how hard she tried she just couldn't resist the urge to press her fingers into her firm flesh, sending wave after wave of pleasure through her mind. Her intense caressing led her orbs to jiggle a little as they gave in a little to her hands, pressing them into a slight egg-shape. It was almost absurd how solid her basket-ball-sized breasts still stood from her body, her thumb-sized nipples pointing directly at the ceiling.
Her massive piles of meat suddenly flared into every direction, mainly to the front as the holes her nipples had created united, granting a generous view on the front of her bosom. Jean stopped her caressing for a moment, her breasts jiggling like two giants puddings inside her hands. A moment later and her V-neck also reached the hole, allowing masses of breast flesh to press through the giant cleavage that was forged by the unison of the tears. The holes on the sides had ripped over the widest parts of her curves, making her shirt look like a way too small bikini top. While her growing mounds continued to destroy the fragments of her top, her bounteous bosom pouring through the rifts, Jean's hands had almost no fabric left to rest on. Her vast under cleavage was already showing more than a third of her bust, the fabric slowly sliding up the ascent of her bust. Jean panted hard and fast, throwing out a weak moan from time to time. Suddenly the thin fabric on the sides of her bosom – the "holders of her bikini" – snapped at her shoulders, moving her bust line forward as her cleavage fused with the rifts on the sides. Jean pulled her head back a little as her breasts pushed against her chin, wobbling forth and back while tearing on the remnants of her shirt. Like a belt the fabric was lying tightly around her bosom, resting only slightly below her nipples. Through the whole laboratory the rubber's desperate struggle could be heard as it stretched around her still growing breasts, getting ripped apart bit by bit. Though she was doing her best to keep her hands off her skin Jean felt the fabric slipping off beneath her palms, forcing her into direct contact with her sensitive bosom. Her whole body quivered in arousal, the trembling of her hands shaking her bosom. With a loud rip the "top" finally broke apart, blowing away like a broken rubber band. Her bare breasts shook and trembled, wobbling into every direction as they had broken through all constrictions.
"Guess I need to work on this super-elastic material some more before I can sell it to the military", the professor mumbled. Having jumped up to the size of medicine balls her breasts pushed against her arms, while her hands were still pressing deeply into her firm flesh. With an open mouth Jean swallowed, holding her breath for a moment. Unhindered her breasts reached out to all sides, outgrowing any reasonable measurements. She crooked her fingers to dig them into the swelling masses, pressing her arms as deeply into them as she could. All the pleasure that had built up inside her was released as she began to rub her bosom with all her might, her flesh wobbling wildly between her arms. Her breath returned, louder and faster than before, her pants quickly filling with pleasure until she only threw out one moan after another. As the last drops of the purple liquid flowed into her Jean rocked her body forth and back on the table as much as she could while moaning in ecstasy.
With a wide grin the professor pushed a button, therefore ending the paralysis. The wires and hoses attached to Jean were ripped out as she rolled to the side, falling right off the table. She almost screamed her lunges out as she hit the cold ground of the basement with her ballooning bosom, and interrupted her massage for a second. But as her firm flesh pressed against the ground and her long blue hair fell over shoulder into her cleavage, tickling her sensitive skin, she quickly began to fondle herself again. Her hard nipples pressed against the ground, hurting Jean a little as they were buried under her swelling bosom. She barely noticed it however through all the pleasant impulses that were sent through her nerves. Putting her head back (because her cleavage was about to eat it) Jean put even more strength into her gropes, pressing her breasts against each other. Her body hopped on her bosom as she kneaded the firm flesh with her hands, sending big bounces through her bust. While Jean felt like she was floating towards heaven her bosom flowed out to all sides, against her arms, the rest of her body and the ground, lifting her a little into the air.
Slowly then, the urges inside Jean subsided. Her moans steadily lost their insensitivity, and her groping became tamer. At a monumental size at which even big beach balls would be close before bursting she could feel no more flesh pouring against her arms, except for the one that was already there. Panting and sweating Jean collapsed on her bust, hopping around on it while she let her arms hang down. Her body was pressing her breasts against the ground, but it only squeezed them into a slightly oval shape, their firmness still apparent. As she pulled her hair out of her cleavage and tucked it behind her ears Jean let out a long sigh, blowing the air against her bosom. Her chin was completely hidden between her breasts, and she could feel some of her mammal meat brushing against her cheeks and lips. "Oh. My. GOD!", Jean brought out in exhaustion. After she had relaxed a little she added: "And I bet you have filmed everything, didn't you?"
With a creepy smile on his face the professor worked on his computer, obviously content with the result of the test. "Visual recordings are necessary for every big experiment", he informed his guinea pig. "And I've already got offers from four large pornography concerns for the video material. Somehow I need to finance my researches, after all. "
Jean groaned. Each of her breaths was making her body move up and down with, reminding her she should get back on her feet. She tried to move her arms past her monstrous bust to push herself up, but no matter hard she pressed and how much flesh spilled against her face, she could only reach the ground with her fingertips. Plus, as her arms pressed against her breasts, her sensitive orbs sent sensual impulses through her nerves again, making her a little shaky in the legs. "I can lift up an entire house, but am unable to get back on my feet", she mumbled in anger while pulling her arms back. Pressing her knees against the ground she knew she had no choice but to lift herself up only with the force of her back muscles. Since she had the control over her systems again she pumped all her strength into her back musculature, her breasts blowing up a little as she took in a deep breath before she started to heave her bosom. The pressure on her breasts slowly decreased as she straightened her upper-body, slowly sitting up. Her breasts pushed back into a rounder shape, while Jean felt the pressure on her breast warts was decreasing. She had to overload some of her muscles, but she was eventually able to lift her breasts into the air, making her giant melons hang proudly from her body. Carefully then she tried to stand up. After fighting with her balance a bit she managed to get fully back on her feet, although she had to lean slightly forward. "How come my breasts feel so heavy?", Jean asked, rowing with her arms not to fall over. "I mean I have the strength of a hundred men!"
"A thousand", the professor corrected her. "And it's because the gravity center of your body has changed."
As if on cue a window suddenly appeared in Alice sight. "CENTER OF GRAVITY CHANGED. RECALIBRATE?" With a single thought Jean agreed. Inside her she felt as the structure of her biomechanical muscles and cells was changing, adjusting to the new set of melons on her chest. Slowly the weight of her bosom felt less heavy, allowing Jean to straighten her back more and more. After a few seconds she was standing perfectly straight, and it felt like there was no weight on her chest at all. Trying to ignore her swollen assets however was still impossible: First, they were still very sensitive, reacting to every small move of her with a tingle. Second, even as she was standing their firmness and roundness could only be described as simply stunning. She couldn't reach to her nipples with her arms, but her bosom still didn't stand any lower than to her thighs. The top of her breasts meanwhile was always in her sight unless she looked up at the ceiling, her cleavage brushing against her chin every time she took in a deep breath or just lowered her head. "Was it really necessary to go that far to test your weird formula? Don't answer", she quickly added as another grin spread over the professor's face. She put her arms around her humongous bust as far as she could, squeezing her firm flesh a little. "Are… are they real?", she asked after a while. "I mean are they all flesh and skin, or just more biomechanical bullshit?"
The professor's gaze went back from Jean's charms to the screen of his machine. "I can assure you they are 100% natural. The liquids I first poured into you contained organic molecules that served as resources for your growth, so there are no technical modifications of any kind. Even the skin is completely unaltered. Go ahead: Try to control the nerves in your tits."
Jean removed her arms from her bosom. Her breasts were still tingling a little, so she first tried to deactivate their sensitivity. The electric impulse went to regions around her breasts, making her numb to any feeling there, but not any further. Jean was surprised. Next she tried to manipulate the muscles in them. Her breasts jiggled slightly as her abs flexed and her arms bulged a little, but otherwise Jean couldn't detect any changes. One by one she tried out all functions that could affect them, from heat sensory to colour change. While all body parts responded to her thoughts her breasts always remained the same firm round mounds they were, only wobbling a little at some commands. As she looked at the giant humps on her chest with big eyes a weird feeling of joy was overcoming her. "Wow", Jean could only say as she put her systems back to normal. After staring silently at her breasts for a while she put her arms back around them. The tingle increased as she gently she rubbed her hands over her skin, while she began to cuddle her cleavage with her face. "They are all me…", she whispered with a smile.
The professor had also been smiling as he watched Jean, raising his voice after a while: "Okay, so about shrinking them back: I'm working on a new kind of laser that can evaporate an entire cement block in less than a-"
"Forget it! I won't let you ever lay a single finger on them again!"
The professor raised an eye-brow.
"You've heard me right! You can think of me what you want, but I will keep them." She pulled her arms tighter around her breasts, closing her eyes as she hugged her meat balls. "Since the accident I have always felt like a stranger inside my own body. It's not enough everybody stares at me like I'm an alien, but often I feel myself like I'm one, like someone who doesn't belong into this world. But now, for the first time in years, there is something on me that I can not control like a computer, that is not more a part of a machine than a human body. Finally, I can feel again like I'm a… a human!"
The professor had still fun watching Jean, although her behaviour was startling him a little. "Just to be sure: You are aware you've got more human in your tits than most people in their entire body?"
Jean let go of her breasts, pulling her head out of her cleavage as it started bouncing. "Fine", she said with a big grin on her face. "If you prefer a flat-chested girl to fly into your lab every month instead of the bustiest woman in the world…"
"Good point. All right, I'll just grow some other part of your body next month and test the laser on it."
Another wobble went through Jean's chest as she began to shudder. "Can't wait for it", she murmured.
