The story so far
In the 23
rd
century, Mike is an information science student at the Tokyo Arcology International University, as the old University of Tokyo is now known. Originally from the English country-side, he is an exchange student living in the massive Tokyo Arcology. Arcologies are city-sized megastructures containing all the housing, industrial, food-processing and business facilities needed for their millions of inhabitants, and they have become quite common as the Earth struggles with overpopulation.
Mike met his girlfriend Michelle and her three friends Kimiko, Rose and Maaya at Professor Sayoko Tamura's class on genetic restructuring, which he had been taking to fill up his extra-curricular credits, and to meet more girls.
The four girls had recently started taking breast augmentation formula, a genetic restructuring agent aimed at enlarging bust size, provided by Kimiko's rich aunt. The completely flat Kimiko had always wanted larger breasts, and pressured her friends into joining her, much to Mike's delight.
Everything was fine until Professor Tamura—who is herself extremely endowed—asked them to take part in testing an experimental rejuvenation formula for the Madihi Fountain of Youth Labs in Casablanca, run by Professor Tamura's acquaintance Dr Bassir. The formula would provide them with additional strength, stamina, vitality, improved metabolism, heightened senses and increased libido, but at this experimental stage would not actually rejuvenate anyone yet. Although concerned about possible interactions between this formula and the breast augmentation formula, they are ensured there is no risk and all five of them—the girls and Mike—agree.
Everything seemed ordinary until two weeks later, when Michelle suddenly grew a full cup size in a matter of seconds, and Mike—who had unknowingly also ingested some breast augmentation formula by accident—noticed his dick seemed swollen. Though they were assured everything was fine after a medical check-up, Michelle remained worried about what was happening to their bodies.
Later that day, Kimiko's chest also grew, though much, much larger, witnessed by Mike. Overwhelmed by their lust, Mike and Kimiko had sex. After regaining their senses, the two of them confessed what had happened to Michelle, consumed by guilt.
The same evening, Rose and Maaya were watching a movie. After the movie, the tall Brazilian lesbian Rose unexpectedly made a move on the diminutive Japanese-Chinese girl. Fuelled by their own horny desires and Maaya's hidden crush on the tall girl, the two of them got it on, only for Maaya to start growing too, and not just her chest. Both Maaya and Rose grow taller, to around two metres fifty and two metres eighty respectively.
The next day, the five of them explained the situation to Professor Tamura. After deciding that the TAIU's medical facilities aren't equipped to deal with something like this, she decides to fly all of them over to Madihi Labs in Casablanca, Morocco, Africa.
After arriving in Casablanca—the richest city in the world—they are met by Dr Lina Bassir, the gorgeous daughter of the other Dr Bassir, her father who is in charge of Madihi Labs. She takes them to stay with her at her massive penthouse apartment in the old part of Casablanca, outside the arcology domes.
After a thorough medical check, the Doctors Bassir and Professor Tamura assure the five of them that they are in no danger at present, and that they will be taken off the breast augmentation formula while they attempt to sort things out. Behind his daughter's and the professor's back, Dr Bassir actually increases the dosage of both formulas for the girls and Mike, eager to understand the growth as it may provide the breakthrough he's been looking for.
Mike has a midnight encounter with Lina in the bathroom, which results in an erotic dream about himself, Lina and Michelle, the two girls growing to immense proportions while having sex with him. This only deepens Mike's anxiety about his relationship with Michelle, and he wonders what the future will hold for them.
When Mike and the girls realise that their public appearances have generated a lot of attention, they hope that the spotlight will prevent Dr Bassir from doing anything too overtly bad to them. However, even as they create more attention by flaunting their new bodies in public, the mainstream media refuses to mention them at all, pressured by the North African Conglomerate and Dr Bassir, and no one is linking their presence in Casablanca to Madihi Labs, which is necessary for their plan to work.
Professor Tamura calls on an old friend, Mary O'Shea, a news reporter for the European Central News Network on-demand feed. She comes to Casablanca to interview Mike and the girls, but not before Kimiko has another growth spurt in public, the result of the increased formula dosage Dr Bassir has been giving them in secret. During the interview, the same thing happens to Rose, who grows even taller during the live broadcast.
Lina discovers that sexual arousal is one of the prerequisites for growth, and Dr Bassir wants to test this theory by adding horniness-inducing chemicals to the food prepared by Lina's kitchen unit without her knowledge. Lina also believes that in order to grow, the person also has to want to grow, but her father dismisses that hypothesis.
That evening, Mike, Michelle, Maaya, Kimiko, Rose, Lina and Professor Tamura, as well as their guests Mary and her assistant Dylan, are all exposed to the horniness-inducing chemicals. Their rising desires lead to a sex-filled night in and around the hot tub, with Kimiko growing truly titanic breasts and Maaya, Rose and Michelle all growing into mini-giantesses.
During this night, Dylan gets it on with Kimiko, who he'd always had a crush on from her days as a professional swimmer. Mike gets an opportunity to prove himself to Michelle as he refuses Maaya's lust-fuelled advances, and Lina joins Mike and Michelle for a threesome of sorts. Michelle proves to Lina that wanting to grow definitely is part of the process, as she shows she can control it quite well.
Unfortunately, the night ends prematurely when all are knocked out cold by a gas grenade. Mike and the girls are taken away by Dr Bassir so he can experiment on them without scrutiny, and the others are left behind.
Part 5: Outgrown
It was already light out by the time Lina woke up, and she found herself lying on top of the covers on her bed. Her whole body felt sore, no doubt from the exertions of the previous night. Especially from when she'd been bouncing on top of Michelle's tit while the giantess fucked Mike, she remembered fondly.
She wasn't entirely sure how it had happened, but last night had been by far the best night of her life. Seeing all the girls grow to such extreme proportions was just so unbelievably hot. The two giantesses Rose and Maaya making out... Dylan getting overtaken by Kimiko's absurd chest... then finally Michelle's stunning beauty as she grew both bustier and taller, and Lina's own participation in that.
Really, her only regret was that she hadn't been able to join in the growing. It seemed to feel so good to them, and she wanted to know what it was like. Perhaps one day she'd be able to experience that as well.
Her hands caressed her dark skin as she recalled the previous night. Her excitement rose as she replayed the events in her head: lying underneath Michelle's massive tits, riding on top of them, all of them falling over after Mike came, and then...
Wait, what happened after that? Lina sat up straight in bed as she suddenly realised she had no memories beyond that point. She didn't even know how she'd gotten in bed. And why was she on top of the covers anyway, rather than under them?
Come to think of it, it was beyond weird she was in bed alone. Why wouldn't she be sleeping with Mike and Michelle after an experience like that? Had something happened to make them not want to be with her anymore?
Frustrated that she couldn't remember, Lina got up. She ordered the curtains open, and sunlight streamed into her room, caressing her bare skin. She couldn't enjoy it this time, the gap in her recollections was bothering her too much.
She strode out of the room, still naked, her heavy Double-Ds bouncing with every step. After yesterday, she didn't exactly feel the need to be modest anymore in the presence of her new friends.
The house was quiet. She walked to the living room, and found it empty. The deck was equally deserted; the chairs and table were strewn about, a result of the activities that had taken place there, and the hot tub was still open, but there was no sign of life.
Lina was starting to get worried. She'd been expecting at least Rose, Maaya and Kimiko to be asleep on the floor in the living room or something, since they hardly still fit in their beds, or even their rooms for that matter. However, there was no one there.
She walked back out of the living room, and stopped at the door to Mike and Michelle's room. She couldn't hear any sound from inside; could her gorgeous giant friend and her boyfriend really just be asleep in there?
She knocked, and when there was no answer, she opened the door. The room was just as empty as the rest of the house so far. She couldn't tell if it'd been used; the covers were messy, but she knew Mike and Michelle had had sex before the interview with Mary, and it was unlikely anyone had made the bed since then.
She checked Rose and Maaya's room next, but it was deserted too. She then looked in Kimiko's room, feeling somewhat foolish; there was no way the Japanese girl's chest could've fit through that door. Unsurprisingly, she wasn't there.
Now Lina was really worried. Kimiko was immobilised by her giant chest, and even if Rose and Maaya had carried her, she couldn't have left the house. She wouldn't have fit through the door, or in the elevator.
Lina was almost beginning to wonder if the last couple of days had just been some kind of weird dream when she opened Professor Tamura's door and found the busty green-haired scientist sleeping, lying on her side, also on top of the covers and naked.
"Sayoko!" She called as she shook the sleeping woman's shoulder, causing minor quakes in her massive J cups.
"Lina, what are you..." Sayoko began groggily. Then, she suddenly opened her eyes wide and sat up, causing even more jiggling action. "How did I get here?"
"You don't remember?" Lina asked, a note of panic in her voice.
Sayoko shook her head. "No... the last thing I recall is having sex with Rose and Maaya, nothing beyond that." She frowned, concentrating. "No, actually, I remember my head getting heavy. I must've passed out, I presume. Did someone carry me here?"
"Not me. I woke up in the same state as you, and I haven't found anyone else yet."
Sayoko looked alarmed. "No one?"
"I haven't checked Mary's or Dylan's room yet, but there's no trace of the others."
Sayoko shook her head, confused. "How could Kimiko have left?" She wondered. "She would've needed to be airlifted from the building."
"That's what I was thinking. It makes no sense!"
The two of them went over to Mary O'Shea's room, and they found the red-headed Irish news anchor sleeping peacefully, her large chest rising and falling with each breath. When woken, she was equally clueless about what had happened. Dylan was in much the same state in his room; the normally shy guy was much too distressed by the news of the others' disappearance to even be embarrassed by three beautiful naked ladies in his room, while he was equally nude.
"Kimiko's gone?" He asked, his voice shaking. "And the others?"
"It seems so," Sayoko said.
"This is ridiculous," Lina said. "I'm calling Michelle."
