Outgrowing the Arcology

Written by Dilandau ([email protected])

You know the drill: this story contains scenes of a sexual nature, and breasts of ever-increasing dimensions. If you’re too young or – for reasons that I’m unable to fathom – don’t like large breasts, then you probably shouldn’t be reading this.

Part 1: The Girls of District D

Mike groggily walked out of the bathroom, applying shaving cream to his face as he made his way to the kitchen. The cream quickly eliminated this morning’s stubble, leaving him completely clean-shaven without any effort on his part. He actually still preferred to use a razor, but according to Michelle “everyone who lives in an arcology uses shaving cream,” and thus she didn’t let him use his own shaving supplies whenever he spent the night at her place.

Unfortunately, all that spending the night entailed was sleeping on the sofa-bed in the living room. Mike and Michelle had been dating for a while, but so far the physical side of their relationship hadn’t progressed beyond kissing. However, Mike was hopeful that this holding pattern would soon break.

Mike walked into the small kitchen, and ordered up some bacon and eggs with toast from the kitchen unit. While he waited for it to prepare his breakfast, he realized his throat was parched, and grabbed the glass of orange juice that was on the counter. Michelle had probably poured the glass for herself, but he could always get her a new one if she wanted.

When the kitchen unit announced his breakfast was ready, he took it and walked into the living room – or what qualified as such in arcology housing on a student’s budget. He hit the button on the side of the sofa-bed with the tip of his toe, and it neatly converted back into a sofa, after which he sat down.

“Good morning, sleepy-head,” he heard Michelle call from behind him. She emerged from her bedroom wearing a loose fitting night-shirt, showing off her marvellous figure. Michelle was about one metre ninety, but her length didn’t make her lanky in the slightest; in fact, she was still quite curvy. Her straight dark-brown hair hung down to just under her shoulder blades, and her eyes were a bright emerald green. Michelle’s younger sister, Lucy, had confided in Mike that that was not Michelle’s real eye colour; she had changed it because she felt her original hazel brown colour was too unremarkable amidst the scores of brown-eyed Japanese girls in the Tokyo Arcology.

With the top few buttons of her night-shirt left open, Mike was able to see the modest curve of her breasts, and even just a hint of nipple. They were only a mere B cup, but they did seem slightly fuller than two weeks ago. Two weeks ago; that was when Kimiko had made the proposal, and Mike still couldn’t quite believe that Michelle had agreed to it. Not that he was complaining about it.

“Watch where your eyes are wandering,” she said teasingly, but she made no effort to draw her shirt together. “There’s no way it could be visible yet.”

“I need to get good baseline data,” Mike said with a lopsided grin on his face. “That way, we can confirm the changes logged in your biometric chip with visual inspection.”

“Right, Professor,” she replied. “Save the science for the lab, will you. Although… maybe a manual inspection would be warranted…” She began rubbing her breasts through the shirt, throwing her head back and moaning in an exaggerated fashion, leaving Mike to gape at her open-mouthed.

She stopped, and stuck out her tongue. “You are so easy to manipulate! That look on your face is priceless.”

“Yeah, yeah, whatever,” he said, shrugging as Michelle walked into the kitchen. He tried to appear nonchalant, but privately he was quite glad that the tray with his breakfast prevented Michelle from seeing what was going on beneath it.

After a few moments Michelle returned with her own breakfast, including a fresh glass of orange juice, quietly sitting down next to him on the couch. “Are you watching the weather report again?” she asked. “It’s not as if we’re going outside, you know.”

“Force of habit,” he said simply. Unlike Michelle, he hadn’t grown up in the Tokyo Arcology, or any arcology for that matter. He was part of the ever-decreasing part of humanity that knew what it was like to see sky out the window.

“And speaking of habits,” she said, gesturing at his breakfast tray. “Why are you still eating that crap? You’re not in the English countryside anymore; this is Japan.”

“Hey, there’s no way I’m eating rice for breakfast! I need a good foundation to start the day. And besides, if you ate some bacon yourself once in a while, maybe you wouldn’t need to go along with Kimiko’s wild ideas,” he said jokingly.

“Hah!” she exclaimed, jabbing a chopstick in his thigh. “If I ate like that, it’d all end up in my legs anyway. And we’d better hurry; you know how Professor Tamura gets when we’re late to her class.”

After they had finished eating and had fully dressed, the two of them made their way to the transport tube that they used to get to University. Mike and Michelle were both attending the Tokyo Arcology International University, which is what the former University of Tokyo had morphed into after its main campus had been absorbed into the arcology. Even in the 23rd century, it was still the most prestigious university in Japan. He was working towards his master’s in information science, while she was doing the same in applied genetics.

The two of them had met at Professor Sayoko Tamura’s class on genetic restructuring earlier this year, which Mike had taken to fill up his extra-curricular credits. Though he was actually interested in genetics, he had to admit that the decision had also been influenced by the high percentage of girls in the genetics department at TAIU.

It was a decision that had paid off brilliantly, because after four years of not being able to get dates, he and Michelle had hit it off pretty quickly. Besides that, he now had more girls in his social stream than he could recall having met since moving to Tokyo prior to joining that class, some of whom he even counted as close friends.

Among those girls was Kimiko; the stereotypical genki girl – overly energetic no matter what the situation – who was one of Michelle’s closest friends. She was the one, just two weeks ago, who had come up with the ridiculous plan that was going to make Mike’s life much more interesting, he expected. If anything, it should increase the eye-candy factor, and hopefully the hormonal boost that he had read was associated with it would increase the likelihood of getting some action with Michelle in the near future.

The two of them got into the already quite crowded capsule waiting at their station on transport tube 32-D, one of many running through the support struts in District D of the Tokyo Arcology. They were the primary means of getting around the enormous structure, consisting of multiple overlapping pyramids, which had replaced the old city of Tokyo. Since it was designed to house nearly a hundred-million people, plus all the factories, shops, offices, and even agricultural facilities necessary to support those people, efficient transportation was paramount.

The Tokyo Arcology was the first of its kind, completed in 2112 – more than a century and a half ago – to support the country’s massive overpopulation. Since then many other cities had followed suit: London, Paris, New York, Los Angeles, Moscow, Johannesburg, Mexico City, Rio de Janeiro; all around the world nearly every major city had converted into an arcology. It was the only way the planet could sustain the now twenty billion humans that lived on it, and that number was still growing.

As the transport capsule sped along its course, Mike took the time to check his social stream. All the information he was interested in was projected directly into his retinal implant. His social stream told him that Kimiko had sent him another message asking whether he and Michelle had had sex yet. For some reason she had made it her life-mission to get the two of them two sleep together, ever since they had started dating.

After checking what some of his old friends back in England had been up to, he switched to the news. He always watched the European Central News Network aggregation feed; it was easier than configuring his stream manually to watch for stuff he would be interested in, and besides that he enjoyed Mary O’Shea, the busty red-headed Irish news anchor they used.

“This is ECNN on-demand, I’m Mary O’Shea, and welcome to the news,” she began. She was wearing her usual professional white blouse and charcoal-grey blazer, which although fairly modest did little to hide her bulging chest.

“Our top story today is that the Madihi Fountain of Youth Labs have reopened after the damage from last month’s terrorist bombing was repaired,” Mary began the news. “The reopening once again triggered many public demonstrations in the Casablanca Arcology, home of Madihi Labs. The laboratory has been the topic of much controversy over the past year as they continue to work on the new genetic restructuring technique developed by Doctor Bassir, which he claims will be able to rejuvenate a person, effectively providing eternal youth. We asked him for commentary.”

The scene changed, showing Doctor Bassir standing in a stereotypical biology lab. He was an African man in his late middle-age, with greying hair and a distinguished air about him. Mike had the feeling he’d seen him somewhere before.

“I understand that many people are concerned,” Dr. Bassir began in a heavy Moroccan accent. “They think that enabling people to live longer when the planet is already overpopulated is a bad idea. But these people are not looking at the whole picture; our methods will also improve cell metabolism and the efficiency of many of the body’s systems. It will allow people to survive on very little food, so they will consume far fewer resources. Additionally, longer life will hopefully reduce the reproductive drive which could lead to an actual reduction in population. And in the long term, eternal youth will make it feasible to send people on colony starships to other stars; no one wants to spend most of their life travelling through space, but when you can live forever, a few decades won’t seem so long.”

The scene switched back to Mary. “Dr. Bassir says he will continue his research in spite of the continued opposition. When we asked John Robson, once of Bassir’s primary opponents, for comments, he said that Bassir is ‘a stupid bastard who is full of shit’, and that ‘he should get on a starship himself if he loves that so much.’ Robson declined to appear on camera.

“In our second story, Dutch engineers have finished land reclamation in the North Sea and are ready to begin construction of the North Sea Arcology. The new arcology is expected be completed by 2285, and will provide capacity for almost two-hundred million inhabitants, making it the largest sea-based arcology yet constructed…”

Mike’s news-watching was interrupted when they arrived at the Ochanomizu station, and Kimiko entered accompanied by their friends Maaya and Rose, another exchange student. The three of them together always made for a comical sight: Kimiko was an average Japanese girl in almost every way, while Maaya was a diminutive half-Japanese, half-Chinese who was positively tiny at just one metre forty-five, and Rose towered over both of them at more than two metres.

Rose in particular was a sight to behold. Not only was she very tall, but the Brazilian girl also had an exceptional hour-glass figure, smooth dark skin, beautiful wavy black hair, and a D cup chest. Top that off with a face that was so hot that it could probably re-start global warming and it wasn’t strange that every single guy in the transport tube turned their head to look at her. Of their little group of friends, it was perhaps the strangest that Rose had also joined in with Kimiko’s plans, already being blessed with such natural assets.

Mike had been quite interested in Rose when he first joined Professor Tamura’s class, but unfortunately for him – and really, it was a loss to the male sub-species in general – she was a lesbian. She had also made it quite clear to him that any jokes about being fine with it as long as he could watch would end with him face-down in Tokyo Bay.

It wasn’t as if he could complain, though. He’d definitely struck gold with Michelle, and as long as he and Rose were friends, he could at least look at her. It hadn’t taken him long to record enough images of her using his retinal implants to enable the not-entirely-legal undressing software he owned to create a ninety-five percent accurate model of what she looked like naked. It had made for some very satisfying wanking material.

Against his better judgement, he switched the program on in virtual mode. It seamlessly replaced the four girls in his vision with their naked counterparts, overlaying the virtual images over the real girls using his retinal implants. Although the images were just approximations, since he had no basis for comparison it was completely indistinguishable from actually being in the transport tube capsule with a bunch of naked girls. He grinned inwardly; undressing software may be illegal, but it was well-known that most of the population used them. The Eurasian Union had long since given up trying to ban the software completely, instead focusing their efforts on keeping it out of the hands of minors.

He briefly admired Rose’s ample assets – though they looked smaller than they were on her large frame – and Michelle’s almost equally stunning figure. Rose had large dark areola, whereas Michelle’s breasts were capped by modest pink nipples, although admittedly that was mostly guesswork on the program’s part, especially for Rose. Finally, he reflected on the two Asian girls. Both of them were undeniably cute, and Kimiko even had some actual curves around her hips, but they both almost completely lacked breasts. In fact, he strongly suspected this image was actually overestimating Kimiko’s breast size, as he was fairly sure she padded her bra, which the program hadn’t taken into account.

Of course, that situation would likely change soon. As that thought entered his mind, he activated one of the equally-illegal plug-ins for the undressing software that he liked to use. As he did, all four girls’ breasts began to slowly increase in size. Kimiko and Maaya both went from non-existent chests to respectable C cups in a matter of seconds. It was amazing how much difference that made; it turned both girls from merely cute into certifiably hot, especially with Maaya, where the firm new globes looked even larger due to her short stature. Meanwhile, Michelle was passing softball size, and Rose’s breasts were approaching basketballs. He couldn’t help imagining being smothered by those imposing orbs; and thanks to her length, they were pretty much at his face-height anyway.

It was an incredibly erotic sight; in fact, dangerously so considering he was standing in a public transport capsule. This kind of thing was better left for more private moments, but Mike had never been particularly good at controlling his impulses in this regard, and the impending real change the girls had committed to only made that worse.

“Hey, ground control to Major Mike,” Kimiko yelled, snapping him out of it. “What planet are you on? I said ohayō.”

He quickly switched the program off, returning the girls to their normal clothed state. “Ohayō,” he said sheepishly. “Sorry, I was watching the news.”

“A likely story,” Rose said, giving him a shrewd look. “He was probably imagining what we look like with larger breasts.”

“Don’t be stupid,” Kimiko came to his defence. “Did you see the bit about the rejuvenation research?” She asked him.

“Yeah,” he said. “Did that Dr. Bassir guy look familiar to anyone else? I can’t help thinking I’ve seen him around here somewhere.”

“I don’t think so. He’s probably just been on the news before, that’s how you know him,” Maaya said, shrugging.

“No, I think Mike’s right,” Michelle said. “Professor Tamura used to work with him at Madihi Labs before she came to the TAIU. I think they still collaborate sometimes, so he probably visited her here.”

“I guess his story checks out,” Rose said sardonically. “You really were watching the news. I suppose the glazed look was because you were lost in Mary O’Shea’s cleavage, then.”

Kimiko gave her a scornful look. “Oh come on; as if you wouldn’t make a pass at her if you’d have the chance. Even I wouldn’t mind getting my hands on that pair of hers, and I’m straight!”

Mike just stared at his shoes; this conversation topic wasn’t helping his already high level of arousal, and he still had a class with Sayoko Tamura to look forward to.

“Anyway,” Kimiko said while lifting herself from the ground by one of the hand grips for standing passengers. “My fellow Double-Ds, are you all keeping up with the program?”

Mike grinned. Double-Ds was the name Kimiko had given their little club; it had started out as “The Girls of District D”, then “The Girls of Double-D”, and finally had mutated into just “Double-Ds”. Kimiko also liked to include Mike under that moniker nowadays, much to his occasional embarrassment.

“I did,” Maaya replied eagerly. “I’ve taken it every morning, just like the instructions said.”

Rose merely nodded. “I just wish the stuff tasted a bit better.”

“You should mix it with something,” Michelle said. “I drink it with orange juice, myself. You can barely taste it then.”

“Is that safe?” Maaya asked.

“Yeah, I checked the instructions; they say it can be safely mixed with basically anything.”

“I’ll keep that in mind, then,” Rose said. “It might help.”

“Awesome!” Maaya said, jumping up and down, much to the consternation of some of the other passengers. “We should start seeing the results soon! Remember our goal: the Double-Ds should be real double-Ds before we turn twenty-five.”

“That should be easy,” Rose joked. “I don’t have far to go, and my birthday isn’t until December.”

“Mine is next month,” Maaya said softly. “I might not make it…”

“Then you’ll get there shortly after, anyway!” Kimiko said undeterred. “We’ll be the envy of every girl in the arcology.”

“I think Rose already is,” Mike said jokingly, earning him a cross look from both Rose and Michelle. “And Michelle too,” he therefore added hastily, this time getting a glares from Kimiko, while Maaya just looked at the floor. “I’ll just stop here before I dig myself in any further.”

“Good idea,” Rose said sharply.

Just then, the transport tube came to a halt again, and the display indicated they had arrived at the TAIU biology campus. “Race you to class,” Kimiko announced and ran out of the door.

Maaya hurried after her, while Mike, Michelle and Rose stayed behind and walked at a more normal pace.

“That girl has enough energy to rival the Shin-Osaka fusion plant,” Mike remarked.

“Honestly…” Michelle sighed. “I can barely do anything this early in the morning, definitely not before some coffee, and here she goes bouncing all over the place.”

“Hopefully she’ll calm down a bit once she gets some tits,” Rose remarked. “She’ll find out soon enough that running and jumping around with large breasts is uncomfortable.”

Michelle shrugged. “I doubt it’ll make any difference. Speaking of which, I still don’t understand why you’re taking augmenters too, Rose. It’s not as if you need it.”

“I could ask you the same thing,” Rose replied.

Mike nodded. “I was wondering that too,” he said. When both Rose and Michelle shot him incredulous looks, he added: “I mean it! I’m not just saying that because you’re my girlfriend, Michelle. You look stunning already, you don’t need augmenters.”

“That’s sweet of you, but somehow I don’t think you’ll be complaining if I do hit that double-D mark.” Michelle said, winking.

“True, but still…”

“I’m just doing it out of solidarity; Kimiko said she and Maaya didn’t want to be the only ones taking them. And I actually wouldn’t mind having a bit more up top. Hanging around with Rose here can make any girl feel inadequate.”

“Hey! Don’t blame your insecurities on me,” Rose said. “Besides which, these two” – she cupped her breasts – “have got nothing on the prof. She can make me feel inadequate!”

“Oh please; you’re much better looking overall than Tamura.”

“Jesus wept, girls!” Mike said, throwing up his hands. “You’re both gorgeous, and about to be even more so. There’re plenty of girls who’d kill to have either of your looks.”

“Kimiko and Maaya aren’t so bad either, actually,” Rose added. “They just need to learn to emphasise what they have, rather than obsess about what they don’t.”

“That’s true, but put yourselves in Kimiko’s place,” Mike said. “She’s always felt self-conscious about her body, she’s friends with two of the best-looking girls in Eurasia, and her professor has a chest that makes even them jealous. So when her rich aunt offers to buy breast augmentation formula for her and her friends, did you really think she’d pass that up?”

One by one, the students filed into the lecture hall. Since this was an advanced class there were only about forty of them in total, and out of those there were only six guys, including Mike. When Mike first joined the class he had wondered why there weren’t more guys who followed his example and joined this class just for the view, but he soon discovered the reason: this class was hard, and Professor Tamura, appearances notwithstanding, was very strict.

It was easy to get the wrong impression about Sayoko Tamura. For one thing she was young to be a tenured professor; she was only in her mid-thirties, and she looked even younger. For another, she regularly changed her hair colour using genetic restructuring; currently, it was green after being purple for nearly a year. But most prominent of all, she had absolutely gigantic tits.

That description didn’t even really do her justice: they were easily the largest knockers Mike had ever seen outside the realm of virtual reality. She was the kind of woman you’d expect to see at a sleazy bar; certainly, no one would ever guess from her appearance that she had three Ph.Ds. and was a Nobel laureate. But in fact, the only thing bigger than her chest was her IQ!

She was one of the leading experts in genetic restructuring, which was a hot topic right now. Genetic engineering was easy; it was common practice to remove genetic defects or propensities for disease before a child was born. But modifying the other aspects of an unborn child; that was taboo. Sure, you could engineer a child to be taller, or stronger, or bustier, or have blue eyes if you wanted to, and there were black market doctors that would do it for you, but it was highly illegal and considered immoral; after all, the child had no choice in the matter since he or she wasn’t born yet.

But genetic restructuring was different. It made it possible to change someone’s genetic code and dynamically restructure each cell in the body to adapt to the changes. It meant that if someone wanted to be taller, they could have their DNA re-sequenced to include the right sequences for greater height, and careful treatment meant they could grow into it even if they had already finished growing naturally. It didn’t have the stigma of genetic engineering, because you chose for yourself to use it rather than parents choosing for their children.

The breast augmentation formula that Michelle, Rose, Kimiko and Maaya were taking was a simple form of that; the mixture they took each morning altered their DNA to allow for larger breasts, and included additional components to stimulate the actual growth. It was still very expensive, as the mixture had to be specially made for each individual person and the amount of growth they wanted; if someone else took it, it would have no effect since it wasn’t tuned to their DNA. If it weren’t for Kimiko’s aunt there would’ve been no way the four girls could’ve afforded it.

Being a relatively new technology, the full possibilities of genetic restructuring hadn’t been realised yet. It was scientists like Professor Tamura and Doctor Bassir who were redefining what could be done; the rejuvenation work was just one example of that.

Mike sat down, and his desk in the lecture hall came to life and brought up all the materials he would need for this class, interfacing with his retinal implants. As per the professor’s instructions, he disabled his privacy shield on the implant; she was very strict about making sure that implants were only used for class-related purposes. If she caught anyone playing games or watching movies during class, they could kiss the credits goodbye.

As Professor Sayoko Tamura came into the lecture hall, Mike once again regretted that this also meant he couldn’t use his undressing software during class. It would sure help speed up the occasional boring section; although in truth, it would also speed up his death if she were to ever find out that he’d even considered using it on her.

“Good morning, class,” Sayoko said as she entered the room, her vast expanse of breast flesh bouncing and shimmying with every step. The twin giants were barely contained by a sheer white blouse that was tied up beneath them, showing off an amazing amount of cleavage. It was a testament to Tamura’s teaching prowess that she was able to get anyone to focus on their coursework while wearing an outfit like that.

On any other person, tying your shirt like that would also reveal a good amount of midriff. But for Tamura, it was uncertain whether she even had a midriff. Presumably it was under there somewhere, but it would take a team of experts with specialised equipment to find out. Mike wouldn’t mind doing some… research… on what lay beneath that white fabric himself.

He privately imagined what Michelle would look like with her breasts expanded to that size. He knew she would never go for that, but he could dream, couldn’t he? The thought got him hard again even without the benefit of his undressing program to visualize it for him; growing up in the countryside, he had something that all these arcology kids lacked these days in his opinion: imagination. He didn’t need software to get off.

As a matter of fact, Mike didn’t know what size the girls were going for. The four girls had decided to keep it a secret from each other – and from Mike – what final size they had chosen the formula to be configured for. Kimiko had said it would be fun trying to guess when each of them would stop growing, and as usual she had pressured the others into complying. Presumably, Kimiko herself would be going for a double-D at least, based on her motto, and apparently she was expecting the others to do so too.

With Rose, there was no doubt she would go at least that large, since it was just one cup size anyway. But breasts that size would look huge on poor Maaya, and while he would love to see it, his more practical side had to admit that it would be a bit too much for daily life, unless she could gain some height too. He briefly imagined Maaya as tall as Rose, with breasts like over-large watermelons, even larger than Professor Tamura’s.

He felt his cock twitch in his pants, and he shook his head to get his mind back into reality. He had a class to concentrate on! Damn those girls and their unknowing fuelling of his fetishes. As they kept getting closer to visible results, he found it harder and harder to think about anything else. At this rate, he’d be wanking in the bathroom during lunch break, something he hadn’t done since high school!

Tamura came to a halt before her lectern, and turned to face the class, causing a final breast-quake, straining the fabric of her shirt. The way her tits bulged out of the openings in the shirt only served to fuel his expansion fetishes further; it looked as though she was about to burst through. It was his one regret that the breast expansion plug-in he used for the undressing software could only do its thing while in naked mode; it couldn’t simulate a girl growing out of her clothing. He had searched in vain for a plug-in that could, and had vowed that one day he would learn enough about augmented reality software to write it himself.

“All right, everyone,” the professor said. “Last time I asked you to read that paper on the modifications necessary to the lymphocytes to prevent the immune system from attacking a restructuring agent. Today I’d like to discuss how you think that impacts the design of the artificial DNA rewriting enzymes that are the key to genetic restructuring.”

He sat up, and with great effort, banned all thoughts of breasts from his mind. Professor Tamura interacted with her class a lot, so not paying attention was a death sentence. Her classes were more like a discussion than a lecture, and it was part of the reason why Tamura was one of the few remaining university docents that didn’t offer online versions of her curriculum; she felt that without the dialogue, following along with her classes was pointless.

Mike thought she was probably also afraid that if she did record virtual lectures, they’d be modified into porn videos in no time; a fear that was not entirely unjustified. All the same, there was no denying that Tamura was one of those rare professors who was actually a good teacher, and Mike enjoyed her classes for more than just the titillation factor.

The class itself proceeded with Mike only slipping into tit-sway induced hypnosis a handful of times, and he felt that, hopefully, he’d be able to make it to the end of the day without needing relief; though an extended bathroom visit followed by a cold shower was definitely warranted by the time he got home.

“That’s it for today,” Tamura called. “I’ll post a link to the paper I want you to read for next week on my social stream; it’s called ‘on the effective use of mRNA in DNA restructuring’ and I think you’ll find it interesting. Now get out of here and find some food to keep those brains fuelled!”

Rose and Michelle approached Mike while the rest of the class was beginning to leave. Rose had taken off the coat she was wearing on the transport this morning, revealing a tank top that, unlike with Tamura, did show off a good amount of impressively toned midriff. By comparison, Michelle’s simple t-shirt and jeans were much more conservative, yet what they hid only encouraged the imagination.

“Keeping up, country boy?” Rose asked teasingly.

“Of course,” he said. “Maybe you just find this more difficult due to the lack of oxygen up there?”

“Oh, very original. I’ve never heard that one before,” Rose replied sarcastically.

“That was an awesome class!” Kimiko shouted as she jumped into their midst, startling all of them.

“It was okay,” Michelle said. “Personally I would’ve liked to go into some more depth about the actual process used by the enzymes to reformat DNA.”

Professor Tamura approached them from behind. “You are always free to come to my office for further discussion, Miss Meyer,” she addressed Michelle. “You know I encourage such initiative in my students, especially ones as bright as you.”

“Thanks, Professor,” Michelle said, blushing. She wasn’t very good at taking compliments.

Tamura crossed her arms in front of her, a move which almost pushed her cleavage up to her chin. It made it very hard for Mike not to stare, and he couldn’t help but notice that Rose was having similar trouble keeping her eyes off the professor’s assets. Mike had long suspected that Rose was as much of a tit-girl as he was a tit-guy, which only served to enhance his fantasies of her lesbian exploits.

“Actually, I was hoping to talk to you now, Miss Meyer, if you don’t mind,” Tamura said. “There is an opportunity I would like to discuss with you.”

Michelle looked at Mike and the others. “We did have lunch plans, Professor, but if my friends don’t mind waiting…”

“Oh, but they can come too. I actually need a few people for this, and they might be interested as well.”

Their curiosity piqued, the five of them followed Tamura to her office. As a tenured professor and one of the faculty’s most distinguished members, she actually had an office with a real window to the outside. It looked out through the arcology’s superstructure, and from this height they could see right across the bay to Yokohama on a clear day like this, even though they weren’t even particularly close to the bay. Yokohama still had numerous old-fashioned skyscrapers and other buildings, but most of them were already empty in preparation for demolition, to be replaced with the latest expansion of the Tokyo Arcology. The way this was going, Mike suspected that a century from now, all of Japan would fall under the arcology’s roof, the other city arcologies merging with it as it grew.

Tamura sat down behind her desk, and motioned them to take seats in the various chairs in the office. She leaned forward on the desk, compressing her tits against the faux-wooden surface. “So, how would you like to earn five-hundred thousand yen each?”

That sure took them by surprise. Mike quickly converted the number to Euro-rouble in his head – something which he still hadn’t managed to stop doing, despite having been in Japan for several years. It wasn’t a fortune, but it’d sure help to get some better furniture in his apartment. Or maybe he could get some upgrades to his implants; he’d heard there were new models that simulated full-sensory perception, which meant he could simulate a proper breast expansion fantasy where he’d be able to touch as well as see the growth.

Jesus wept, I’m turning into a dirty old man at the age of twenty-four, Mike thought to himself.

“I didn’t think the university had student jobs that paid that well,” Rose said. “Is this on the level?”

“Of course it is,” Tamura said, sounding affronted. “But it’s not for the university. Have you ever heard of Madihi Labs?”

“They were on the news this morning,” Mike replied. “They’re working on that rejuvenation research.”

“Exactly right, Mister Conrad,” Tamura continued. “My old friend and mentor, Doctor Bassir, works on that research, and Madihi occasionally collaborates with my lab here at TAIU. In particular, we have been working on the cellular strengthening that is part of the rejuvenation process. It’s fascinating work.” She looked at Michelle. “And if you, Miss Meyer, are willing to consider pursuing Ph.D. in that direction, I would be willing to sponsor you; you are one of my brightest students after all. In fact, all four of you girls are among the top of my class.”

Michelle simply turned crimson and said nothing, while Mike felt a bit insulted that he was being left out, but since genetics wasn’t his major, he didn’t care too much.

“But what does that have to do with your offer, Professor?” Rose asked, keen to get to the point.

Tamura sat up straight, jutting out her breasts; it seems she simply couldn’t make any movement without somehow emphasising her chest. “Well, here’s the thing. Madihi Labs has just restarted work, and before their research was halted last month, they had just gotten approval from the North-African Conglomerate to start human testing. Simply put, I’m looking for subjects.”

“We get to live forever?” Kimiko asked excitedly.

“Not quite,” Tamura replied. “The project isn’t at that stage yet. This would primarily test the impact of the secondary effects. Expected results include increased muscle-density, improved vision, heightened senses, increased stamina and even an increased libido; though I scarcely think you really need that at your age. And finally, you will require less nourishment, being able to extract more energy from smaller quantities of food.”

“I don’t know,” Mike said. “It sounds rather… invasive. And what if something goes wrong?”

“I wouldn’t ask this of you if I didn’t think it was perfectly safe,” Tamura said. “Do you really think I would risk my star students if I thought there was any chance of something going wrong?”

“I guess,” Mike said, shrugging. One the one hand, the process sounded a bit scary. On the other hand, the effects would be neat, and the money admittedly was good.

“What about that muscle-tone thing?” Michelle asked. “I don’t want to look like some body-builder, all muscle and no curves.”

“No, you misunderstood,” Tamura said. “It increases muscle density and efficiency. That means you’ll get stronger without really looking it; you’ll just look healthy and athletic. If you’re concerned, I’ll let you in on a little secret: I’ve been taking the formula myself for nearly a month, and you probably haven’t even noticed any change in me.”

“You’ve been using it?” Rose asked, surprised.

“Yes, and as you can see, it didn’t affect my appearance, but the extra strength has sure helped me carry around these puppies, even though I’d already had my back muscles improved before. It has also improved my skin strength, so I can actually go braless on occasion without sagging to my knees.”

Now it was Mike’s turn to turn crimson. There was no doubt about it now; this day was going to culminate in a wanking session to end all wanking sessions.

“We’ll do it!” Kimiko said enthusiastically.

Rose shrugged. “Well, I guess I could use the money.”

“Wait, Professor, there is one other thing,” Michelle said. “The four of us have been taking breast augmentation formula recently; that wouldn’t cause any side-effects, would it?”

“Ah, good thinking, Miss Meyer,” Tamura said. “I don’t believe it will, as the formulas target different parts of your DNA, so it should be safe to use both at the same time. I’ll double-check it though, as so far I’ve been the only test subject, and obviously I’m not using augmenters; if I got any bigger, I probably wouldn’t fit through doorways anymore.”

At that moment Mike cursed his imagination, as inexorably an image of Professor Tamura with breasts so large that they jutted out far enough to the side to prevent her going through doors entered his mind. The image was quickly replaced with Michelle with the same set of breasts, and it was all he could do to prevent himself from drooling.

“Anyway,” Tamura said. “I won’t keep you from your lunch any longer. I’ll check on the augmenters and I’ll request your medical files as well to check for other problems. And if there are no issues, I’ll have a batch of formula made for your DNA and ready by tomorrow; we’ll finish the paperwork concerning things like liability and payment then. That’ll also give you some time to decide if you really want to do this, as I don’t want to pressure you.”

As they left the office and prepared to go to lunch, Kimiko was the most exuberant of all of them. “Five-hundred thousand yen! Now I’ll be able to get an entire new wardrobe to show off my new figure after the augmenters finish their job!” She jumped in the air excitedly, and ran ahead of them.

That evening, Mike and the Girls of District D went out for dinner to celebrate their new-found wealth in their favourite izakaya – a Japanese-style pub that serves food and drinks – in District E, which covered roughly the area of the old Shinjuku and Shibuya wards. It was a great place and Mike loved going there, but it did mean further postponing his desperately needed private time.

Mike always enjoyed going out with the four girls, if only for the envious stares he’d get from other guys, especially on account of Rose and Michelle. He also loved it when inevitably some cocksure drunk Japanese guy would try to hit on Rose and got his ass handed to him. It was great seeing their egos crushed beyond repair. Meanwhile, Rose herself was trying to pick up the cute new waitress, who seemed terribly intimidated by the tall Brazilian.

After plenty of food and more drinks than they really should’ve had on a weekday, they returned home, with Rose, Maaya and Kimiko parting ways at their station, and Mike escorting Michelle back to her apartment.

When they stood in the corridor in front of her door, Michelle keyed the biometric lock and turned around in the doorway.

“Do you want to come in for a cleansing solution?” she asked him.

“Ooh, anti-hangover chemicals! You are such a romantic,” he joked as he followed her inside.

She threw her coat in his face in mock-offense. “Hey, it’s Tuesday, and I’ve got other classes to attend in the morning. And I want to be sober when signing that contract with Tamura. I’m paying close attention to the fine print there; you never know with experimental drugs.”

“I’m sure Tamura wouldn’t throw us to the wolves; and besides, she’s using it herself,” he said as he dropped himself down on her couch while she went into the kitchen.

She emerged a moment later with two glasses of water with cleansing solution, putting them down on the small coffee table. She sat down next to him, and snuggled up.

“What’s a girl to do?” she sighed after a few moments of silence.

He put her arm around her. “What do you mean?”

“I was always the curvy foreigner around here, growing up amongst the Japanese. But ever since Rose moved here from the Rio Arcology, it’s like I don’t exist anymore, you know what I mean? I rarely get a second glance once they notice her.”

“Don’t be ridiculous,” Mike said. “You’re absolutely gorgeous, and besides, I’m here, aren’t I?”

“Yeah, and would you be interested in me if Rose wasn’t a lesbian? It’s annoying always being second choice.”

“What!? No, that’s not true! Wait… is that why you agreed with Kimiko to take the augmentation formula?”

“Well, it’s part of it. It’s no secret that you love big breasts; it’s not as if you’re particularly adept at hiding the way you look at Rose and Professor Tamura.”

Mike gently put a hand on the side of her face, and looked directly into her eyes. “Look, Michelle, I won’t deny that Rose is easy on the eyes… but that means nothing. And you don’t need to change anything about you if you don’t want to. I don’t care about Rose; it’s you that I love.”

It was out before he realised it, and somewhat to his own surprise, he actually meant it.

Michelle looked into his eyes, and, seeing his sincerity, pressed her lips to his. It was a much more tender kiss than they had ever shared before. When they finally broke the kiss, Michelle looked down, avoiding his eyes. “Do you want to crash here tonight? It’s a bit late to head all the way back to District A.”

Mike was conflicted; he still desperately needed some private time, which he couldn’t get here. On the other hand, after this conversation, he couldn’t really say no.

“Yeah, I’d love to. Though I’m going to need a night’s sleep in a real bed sometime soon; this sofa-bed is not the world’s most comfortable,” he added jocularly.

She still didn’t meet his eyes. “Maybe… you wouldn’t have to sleep on the couch.”

His eyes widened; if she meant what he thought she meant he wouldn’t need private time after all. “What are you saying?”

She stood up, and took his hands. Too stunned to offer any resistance, he let her lead him to her bedroom. The two glasses of cleansing solution stood forgotten on the coffee table.

Before they even reached the bed, they were kissing again, much more passionately this time. Their breath became feverish as their mutual need rose, and as they landed on the bed, Mike progressed from her mouth to her face, briefly licking her earlobe, and moving down her neck.

Michelle moaned eagerly at his caresses. She then gently separated herself from Mike, and made to pull her T-shirt over her head. “Sorry for making you wait; I like to be sure it’s the right thing to do before I go too far with a guy,” she said softly.

“Some things are worth waiting for,” he said as she slowly revealed her beautiful flat belly, and then a lacy black bra.

He reached behind her, searching for the clasp, and failing. Michelle let him fumble for a few seconds before starting to giggle. “It opens at the front,” she said.

Embarrassed, Mike withdrew from his futile attempt and pushed her down to the bed, resuming his attentions to her neck. Slowly his kisses progressed downward, in between the two mountains slowly rising and falling with her breath, and then further down, kissing her belly button, before returning to his true target. Finding the clasp in between the two cups effortlessly, he released her breasts from their fabric prison.

His heart skipped a beat as he paused to admire the sight. Mere centimetres from his face was the most perfect pair of breasts he had ever seen, without exaggeration. Sure, they could perhaps be a bit bigger – and they would be, he realised excitedly – but in shape, firmness and softness they were already unparalleled by anything he had previously experienced, especially up close and personal.

Mike grinned; undressing software definitely didn’t hold a candle to the real thing. He kissed her soft skin in between the breasts again, and then began circling one, planting kisses on her as he went. Slowly he drew tighter and tighter circles until he reached the nipple. He flicked his tongue around the pink, rock-hard nub, eliciting an excited gasp from Michelle. Her breasts seemed to be quite sensitive, which was another tick-mark on Mike’s checklist for the perfect pair. The only box that remained un-ticked was the entry for “gargantuan”, but Mike was more than satisfied with the score achieved.

He paused his ministrations for a moment. “How big did you decide to go?”

She sat up, looking at him slyly. “Wouldn’t you like to know,” she said. “No, Kimiko was right; it’ll be much more fun if you have to wait and see.”

“I never knew you could be so devious,” he said, kissing her again. “Devious and sexy; a lethal combination.”

“Speaking of sexy,” she said, pushing him down this time, “why am I the only one getting undressed?”

She jumped at him, and began pulling down his pants, while he removed his shirt. Mike didn’t have a six pack or anything, but he was in good shape, nothing to be ashamed of. He just wished he was a little less pale; he used to have much more colour before moving to the arcology.

Michelle mewed excitedly as she admired his body, and then finally began to pull down his briefs. Mike shivered a little as her hands brushed his rock-hard member; after all the teasing he’d subjected himself to today, and now sitting across from his beautiful half-nude horny girlfriend, he couldn’t remember ever being more erect.

“Very nice,” Michelle purred. “A bit bigger than the undressing software predicted, even.”

Mike raised an eyebrow at her.

“Oh, what? As if you don’t use it. Everyone does.”

He just grinned back at her silently. In truth, the thought that Michelle had been using undressing software to fantasise about him in the nude turned him on even further, if that were possible.

She lightly caressed his balls, and kissed the tip of his hard cock, before lowering her mouth over it. Mike leaned back to enjoy the blowjob, but Michelle stopped and pushed him flat on his back.

“Oh, no you don’t,” she said. “You can make yourself useful.”

She pulled down her pants and panties, and lifted one of her legs over his face, presenting him with a neatly trimmed bush above a dripping wet pussy.

Mike groaned as Michelle returned her attention to his cock, enjoying the sensual weight of her breasts against his stomach, before turning to his own duties. He was a bit out of practice, but he made up for it in eagerness. He slipped a finger into her slit while attacking her clit with his tongue. From her reaction, it seemed he wasn’t doing too badly.

Unfortunately, Mike had gotten so worked up over the course of the day that he blew his load in her mouth before too long. The orgasm was more intense than any he recalled in recent history, and he had to stop attending to her pussy for a moment to recover.

She got off him, while her fingers still idly played with his deflating organ. “You’d better not be done for the night,” she said.

“Don’t you believe it for a second,” he said eagerly. “This is only the beginning!”

He tackled her back onto the bed, and resumed kissing and sucking on those magnificent breasts, being much rougher this time, while his left hand tended to her pussy, eliciting more loud moans from Michelle. By the time his erection had returned to full strength, her entire body was flushed with sweat.

He repositioned himself above him, and held his cock up in front of her waiting opening.

“Do it,” she said, in such a sexy tone of voice that no warm blooded male would be able to refuse.

He slowly inched his member into her tight, hot pussy. When nearly all the way in, he withdrew again, and then moved forward again, faster this time. He increased his speed steadily, until he hit a steady rhythm.

It wasn’t long before Michelle exploded in her own orgasm, pleasure rocking her entire body. He didn’t slow down, but kept riding her through the whole thing, until the contractions of her vaginal walls sent him over the edge for the second time as well.

He collapsed on top of her, and the two took a moment to recover. But when he wanted to start kissing her again, she got up out of the bed.

“No, enough,” she said. “As much as I’d like to, I do have class in the morning.”

“But I’m up one orgasm,” he said slyly. “That’s not exactly fair to you, now is it?”

“Oh, you’ll have plenty of chances in the future to make it up to me,” she said, giving him a sexy smile, and went into the bathroom to clean up and go to bed.

Later, while the two of them lay spooned against each other in the dark, enjoying the afterglow, a new message arrived in Mike’s social stream from Kimiko, asking him once again if he and Michelle had had sex yet. He didn’t reply.

A note from the author: Since not all of you are likely to be avid readers of science fiction, I feel I should point out that arcologies are not something I invented. The concept and the term – which is a fusion of “architecture” and “ecology” – were popularised by Italian architect Paolo Soleri, and has been used in many works of science fiction, some even predating Soleri. Some of you may also remember arcologies as the final type of structure to become available in Sim City 2000.

The idea of an arcology is that it is a massive structure that supports a very high population density. It combines all the resources necessary to support its population to minimise the environmental footprint and be essentially self-sufficient.
