"Grghh...umpfh...urgh...awww come on...you little...mmrf." grunted Naru.

"No luck, big sis?" asked Mei.

"These things are...mmfph...really...urgh...tight today.  And I really don't know why."  The older Narusegawa sibling was struggling extra hard trying to fit her stockings on the morning after the big sit down in the hot springs.  She was somewhat light-headed after partaking in her share of drinking.  While she couldn't put it away as much as Kitsune, Amalla, or the other older women, Naru was no stranger to letting her hair down and having the occasional shot of sake...or five.  She couldn't quite recall how many she had that night, but she was fairly certain it was less than ten.  In any case, her slightly drunken state didn't explain how her clothing ended up being rather tight and constricting.  And it wasn't just her leggings which she was struggling with.  Every article of clothing she tried on was particularly snug - her shirt, her skirt, her bra and panties, everything felt as if it had been superdried in the laundry and shrunk as a result.  It all felt so darn...small.

"Any luck on your end, Mei?" asked Naru as she struggled with putting on her clothing to the best of her ability, grunting in the process.

"Not...grrh...really...urgh...Naru." responded Mei.  Apparently, her clothing was faring no better on her body than Naru's clothing was on Naru.  Just like her older sister, Mei was struggling to get what she had always worn to fit her properly, which was ridiculous as she had never had fitting problems like this before.

What really surprised Mei the most out of everything was that there was a particularly distinct tightness in her chest.  It was enough to somewhat alarm the girl.  Up until now, Mei had always been flat chested.  And now, after her time in the Hinata hot springs, she could have sworn that her bosom had felt somewhat...swollen?  Inflated?  Enlarged?  It was difficult to pin an exact word at the moment, but sure as the phases of the moon, Mei could have sworn that her breasts had enlarged somewhat during the time she was asleep.  She was pretty sure that she was no longer an A-cup in bra size now.  Probably a B-cup now...maybe even a modest C-cup, but she wasn't sure at that moment.  Some measuring tape would be in order.

"Say, Naru?" Mei asked her sister with a nervous tone of voice.

"Yes, Mei?"

"By any chance, could I maybe..." Mei was trailing off, pondering if she should really ask her older sister what she was about to ask.

"Could you what?" said Naru, trying to get a straight answer out of her sister.

"Could I...try on...one of your bras, by chance?"  Mei was seriously blushing as the words left her lips.

"..."  Naru was momentarily lost for words, staring at her little sister, trying to register what she just heard.

"You..." began Naru, regaining her composure, "You want to try on one of my bras?"  The nervousness and embarrassment on Mei's face was all too apparent at this question being asked.

"Yeah, I know it sounds kinda crazy to ask out of the blue like that, but...I'd like to see something  for myself, if you don't mind."  Naru's face wasn't letting up in how confused she was at this answer, but still she decided to play along.

"Uhh...yeah, sure...no problem.  Here, let me fetch one of them for you."  After rummaging through one of her dresser drawers, Naru presented a plain, tan-colored bra of hers to Mei.  It was a C-cup bra, much like the one she was wearing now (rather tightly too...perhaps it was time to go bra shopping?).  "Here ya go, Mei," Naru said as she handed her somewhat undersized brassiere to her sister.

"Thanks, Naru," replied Mei, examining the item in her hands.  "Umm...by any chance, could you turn around briefly while I try this on?"  The embarrassment in Mei's voice was still going strong at this point.

"Sure, sis," said Naru, walking over to the far corner of her room and stopping with her back turned to Mei.  "Just let me know when you're ready."

"Appreciate it." said Mei.  As she examined the item in her hands, she couldn't help but feel a slight tingle running down both her spine and just a tiny little bit in her loins (much to her embarrassment on the latter).  If what she thought was going to be the case turned out to be true, she was going to be quite alarmed.

After taking off her own shirt - which she noticed was rather snug on her form - Mei proceeded to take the bra that was handed to her and place it around her torso.  After resting the straps upon her shoulders and fastening the back end after some mild difficulty, Mei's suspicions were indeed confirmed.

"Oh my god," whispered Mei, "it's...unbelievable."

"You okay, Mei?" asked Naru, back still turned.  "You need help getting it on?"

"N-no, Naru, I'm fine.  I got it on just fine.  It's just...I can't believe it."  Mei's voice was a mix of alarm and delight at the realization of what she was witnessing.

"You can turn around now, Naru." said Mei.

"Well then, what is it you were..."  Naru failed to finish her statement as she finished turning around.  Before her, Naru's younger sister had miraculously bloomed in her proportions before Naru's eyes.  While her bosom wasn't as large as Kitsune's or Mutsumi's, it was certainly larger than the previous night.  If Naru were to guess, Mei was sporting something between a large B-cup and a modest C-cup in terms of bra size.  Perhaps there was a little spare room within the cups of Naru's bra, but not so much that it hung comically off of Mei's figure.  The revelation was as amazing as it was alarming.  How does a woman whose chest was flat as a board less than twenty-four hours ago end up growing a cup size or two?

As a matter of fact, just how large was Naru's chest, now that she thought about it?

It was only logical to ponder on such a question.  If Naru's bra now fit her younger sister (or came pretty damn close to doing so), and said bra was on the small end for Naru, then just how big were Naru's breasts?  Had hers grown just like Mei's had?  She had after all felt snugness and tightness throughout all her articles of clothing since waking up, so it was only natural for her to have her suspicions.  Just how big were both the Narusegawa sisters now?  And what was the cause of such growth?  Did it have something to do with last night?

As Naru stared at her little sister and her little sister's not-so-little bosom, Naru couldn't help but glance down at her own, taking her hands and slowly caressing her own bosom.  Even with the fabric of her shirt covering them, Naru felt that her breasts were more pronounced than she would have previously noted.  Were they still a C-cup?  Given how snug Naru's bra felt at the moment, she was inclined to think that was no longer the case.  If so, then was Naru a D-cup now?  A E-cup?  The notion was alarming.  What woman grows a cup size or two overnight?  It must have had something to do with that group sit-in at the hot springs.  But what exactly caused it?  And was it a one-time deal, or was it going to continue?  The possibilities were as fascinating to consider as they were alarming.

"So then, Mei," inquired Naru as to her brassiere on her younger sister, "how does it feel?"

"It's...amazing," answered Mei, at little more than a whisper.  "I'm bigger, Naru...I have breasts...real breasts, Naru!"  The alarm in Mei's voice was replaced with joy and delight at this point.

"Well, I'd be lying if I said I was disappointed at this," replied Mei.  "After all, you know how much I've wanted to develop a more mature figure over the last few years.  And it's like my wish has come true now, big sister.  I have boobs...real boobs now!"  The delight in Mei's voice was all too apparent by now.

"Mei," replied Naru, trying to balance the joy in her sister's mood with the alarming reality of the situation, "while I'm happy that you're getting what you want when it comes to your body, aren't you concerned at just how fast you ended up getting it?  I mean, I know that puberty is a time when your body goes through serious changes - trust me, I've lived through them when I was your age.  But this kind of thing takes months if not years to happen...not less than twenty-four hours.  I figured you would be more alarmed than overjoyed by this kind of thing."

There was a momentary pause lasting several seconds between the sisters.  After a good thirty seconds or so had passed, Mei decided to respond to Naru's logical statement.

"Naru," she said, "I admit that this kind of thing is alarming in a way.  From what I remember of my times sitting in health class having to listen to talks about puberty and growing up, I know that this kind of thing takes years to happen.  But even so...I'm happy.  I've finally gotten breasts.  I mean, I know they aren't huge compared to some of the girls I've seen around here, but even so, I actually have breasts!  I've waited so long to have even just a little bit of development in my chest, and now I finally have it!    I only wish you could understand what it was like to have to go through year after year without having even the slightest sign of growth in my bosom or my...well...other parts of my figure."  By this point, Mei was blushing at the idea of having to mention her rear end, which had also shown signs of development along with her bosom.

After hearing of his confession, Naru found herself torn.  On the one hand, her little sister was developing a more physically alluring body in several ways in a rather rapid fashion (the same could be said for Naru herself for that matter).  Such a transformation was rather concerning to say the least.  In all her years of study, Naru has never heard of such a rapid blooming of one's overall growth in such a short time period.  Even infants in the womb don't develop THAT fast.

On the other hand, Naru couldn't help but feel some degree of happiness on her little sister's behalf.  After Mei's confession in the hot springs, Naru couldn't help but shed a minor tear for Mei's predicament (now a former predicament).  At last, her younger sibling would be able to experience puberty and maturing into a young lady, even if it did seem quite rushed.  If nothing else, Naru wouldn't have to worry about Mei pouting and sobbing over having a lack of breasts and curves now.

Even so, what would the other girls think and say at the sight of the two of them.  They would be hard pressed to explain themselves as to how their bodies had become noticeably enhanced overnight after the little pow-wow in the baths.  It must have had something to do with that very sudden euphoric sensation that occurred when they were all sitting in the water.  There was clearly some kind of link.

Another thought just then occurred:  If Naru and Mei had enhanced bodies after sitting in the hot springs - along with all the other girls - then did similar effects happen to all the others?  The idea was as amazing as it was concerning.  Would the other eleven females who lounged in the hot spring waters wake up to find similar results like the Narusegawa sisters?  Would there be changes in their figures just like Naru and Mei - things like their bosoms, bottoms, physique, height?

‘Wait a second,' thought Naru, pondering on that last word.

"Say, Mei," said Naru with minor trepidation in her voice.

"Yes, Naru," responded the younger Narusegawa sister with curiosity.

"Do me a favor.  Could you fetch the measuring tape for me?  There's something I want to look into."

"Uhh...sure thing, Naru.  Where do you keep it?"

"Over there on my desk," elaborated Naru, "upper right drawer if I remember it right."

Sure enough, Mei had found the measuring tape and provided it to Naru.  As she held it in her hands, Naru instinctively gulped at what she was about to do.  While it was nothing harmful in any such way, she simply needed to confirm something that was nagging at the back of her mind ever since she woke up.  From what she could tell, it appeared that Mei was more or less the same height she recalled, being just an inch or so shorter than her.  Yet, her figure as well as Naru's became enhanced, which would explain why their clothes were suddenly so tight and generally uncomfortable, but was it just their curves which had changed?  Was their height also a changing variable?  Only one way to find out.

"Now Mei," began Naru, "I need you to stand perfectly still while I mark your height."  The younger Narusegawa sister complied, standing straight up and looking forward while Naru made a notch along the wall with a pencil.  She then proceeded to use the measuring tape to carefully gauge the distance between the pencil mark and the floor.  From what Naru recalled, Mei should be around a height of 5'3" or so.  As she stretched out the measuring tape, she laid it flush against the wall, expecting the tape to max out somewhere between 5'3" and 5'4".  A moment later, Naru took a momentary gasp as her eyes widened from her discovery.

"Naru," asked Mei with slight worry, "is something wrong?"

"5 foot...6 inches." said Naru at little more than a whisper.

"Wait...what?" asked Mei with widened eyes.

"Your height...it's 5 foot, 6 inches."  Naru was staring at her sibling with wide eyes and a serious tone of voice.

"But...that's just not possible," said Mei, trying to keep her composure, "nobody just grows three inches overnight.  Maybe you measured wrong."

Naru had Mei stand up against the wall once more and made another notch with the pencil.  Sure enough, it was level with the first notch from before.

"Mei," said Naru, "I wouldn't do this to play a trick on you.  You're now five-and-a-half feet tall."

"But...but...that's just not possible," said Mei as emotions started welling up in her, mostly shock and alarm.  "That would make me around your height, maybe even an inch or two taller.  And yet I'm looking up at you.  So...that means..." Mei's eyes widened alongside Naru's at what this train of logic implied.

This time, it was Naru's turn for height measurement.  Up until now, her height had been 5'4", around three inches shorter than Keitaro from what she recalled.  Now that Mei was just an inch less than Keitaro in height, and Naru was taller than Mei, what did that make Naru's height then?  The anticipation made Naru more anxious and worried than curious.  After making her own pencil mark with a different colored pencil, Naru took a deep breath and stretched out the measuring tape to see the result.  Sure enough, she gasped at what the measurement came out to be.

"5 foot 9 inches."  Just saying those words was hard enough for Naru to do.  She was now taller than Keitaro by a good two inches.  She had grown 4 inches in height in less than twenty-four hours!  Now both Narusegawa sisters were shocked and alarmed, with the revelation at what changes were occurring even at that very moment.

"I wonder if the others are experiencing anything like this," said Mei.

"Holy crap!" hollered a 5'5" Sarah McDougal, upon learning of both her height and the sudden development of her body.  In that very moment of discovery, the blonde-haired, blue-eyed girl was feeling up her own bosom, taking in the very weight of her enlarged breasts.  Whereas she was somewhere in the B-cup range the night before, she was now easily in the C-cup range, maybe even a modest D-cup, though that wouldn't be confirmed until she tried on some bras at the clothing shop at the next opportunity.  The sudden three-inch height increase and the swelling of her bosom and tushy would explain as to why her clothes were suddenly more constricting than they were the night before.

"I've got boobs, real freakin' boobs!" declared the boisterous American girl with glee.  "Wait until Shinobu and the others get a look at these."

"I'd wager that given last night, they'll be both impressed and unimpressed at the same time," said a 5'10" Haruka Urashima as she looked for where she placed her cigarettes.  Given the circumstances, she felt a particularly strong nicotine craving after discovering that her clothes were exceptionally tight everywhere, though the bosom was the most problematic of all.  If she were to guess, her bra size was now either a large D-cup or an E-cup by now.  If Kitsune or Mutsumi could see her now, they would probably whistle with surprise, though they most likely would be whistling at whatever changes their own bodies had experienced overnight.

"I'd have to agree with Haruka on this one," said a 5'7" Kanako Urashima, who was petting her cat in order to help emotionally relieve herself at discovering her sudden growth spurt.  While her bosom wasn't anything particularly impressive, Kanako took some measure of pride in her figure.  She knew that prior to the little episode in the hot springs the other night that her figure was more developed than that of Sarah's, Shinobu's, Mei's, Kaolla's, and probably even Nyamo's.  She couldn't help but size up any potential competition for Keitaro's feelings.  The more challengers who matched or surpassed her in physical attraction, the worse things were likely to get.

However, after the incident in the baths, things might get even more troublesome than before.  For while Kanako did appreciate the enhancements that seemed to take place in her body overnight, it appeared that most likely ALL of the women experienced some degree of enhancement from their time in the baths.  After all, everyone was lingering in them for roughly the same amount of time, so chances were good that everyone was exposed to whatever was in the water that brought about such changes.  The sight of Haruka and Sarah were enough to help support Kanako's theory.

"Yeah, well...even so," countered Sarah, "I can't believe how much I've...well...we've all changed.  It's freakin' amazing!"  Sarah would be damned if she was going to let the Urashima women ruin her good time.

"While I'm glad you're taking this well at the moment," cautioned Haruka, "I'd like you to consider a few things."

"Oh yeah?" asked Sarah, "Like what?"

"Clothes for one thing," began Haruka.  "At our current size, our clothing at present hardly fits at all.  As big as we all are now, it'll be near impossible to wear anything that doesn't feel a size or two too small.  And if we happen to continue growing, that problem is going to exacerbate drastically.  Are you okay with wandering around the dorms naked or wearing only a sheet or blanket?"  The point started to sink in, given the reaction on Sarah's face.

"There's food too," added Kanako.  "At our current size, we'll probably need more nutrients and calories than the previous night, given our enhanced metabolism from that little overnight growth spurt.  If we continue to enlarge, chances are good that we're going to need even more calories and nutrients to continue surviving.  Eating the same portions at larger sizes will fail to suffice in warding off whatever hunger pangs we'll most assuredly encounter."  Once again, Sarah's reaction revealed that she was appreciating the seriousness of the situation.

"And then of course, there is shelter," continued Haruka.  "At our current size, sleeping arrangements aren't a problem.  But if we continue to grow in height and overall size, that could be a very different story, especially if the growth comes on fast.  How do you think this room is going to look if we all end up over seven feet tall?  Or eight feet?  Or even taller than that?  And that's with all three of us in one room, mind you."  As was the case, Haruka was an expert in getting her point across when necessary.

"Well...I mean...umm...fine, I guess you've got a point," muttered Sarah, acknowledging the seriousness of the situation.  "Still, I'd be lying if I said I wasn't at least a little happy about this.  And I figured that you guys would be the same way too.  Don't you guys want a knockout body?"

"While your concern for my physical well-being is admirable," replied Haruka, "I'm content with my previous size, thank you very much.  Finding clothes that fit is going to be something of a chore, especially bras now, as mine is practically killing me."  The weight of Haruka's now enlarged bosom was of concern to her, though she pondered if the sight of such a thing would be enticing to Seta if the two of them were to meet now, and then of course there was Keitaro...

"No, stop thinking like that!  Bad Haruka!' thought the older woman to herself, shaking her head and trying to blot out the notion of potentially seducing her younger cousin (technically nephew).

As far as Kanako was concerned, she simply stared at her own enlarged bosom while stroking Kuro in her lap.  She couldn't help but stare solemnly as her pet cat had become noticeably smaller now relative to her.  While that would certainly make carrying her around much easier if necessary, she also worried for her cat's safety.  What if she became so large that handling Kuro was a risky thing to do?  Would Kuro fear her as a result?  The very idea was enough to concern the younger Urashima woman.

Then of course, there was Keitaro to consider.

‘I'm now as tall as Big Brother,' thought Kanako.  The very notion of being able to look her older sibling in the eye was as titillating as it was concerning.  While she was somewhat happy for her enhanced figure, especially her enlarged bosom that was now either a heavy C-cup or a modest D-cup, she was worried what would happen in the days to come if this wasn't a one-time growth spurt.  What if she grew again?  What if she towered over Keitaro?  Would he fear her?  Would he avoid her as much as possible?  As she went down the rabbit hole of hypothetical scenarios, the worry on Kanako's face became more pronounced.  The very idea of the one person she loved above all others fleeing from her was the emotional equivalent to a knife in the heart.

"Well," said Haruka, picking up on Kanako's deflated emotional state, "we had best check up and see how the others are doing.  If it's anything like us, I can only imagine their reactions and how they're going to fare when it comes to their wardrobes."  The other two concurred with her reasoning as they went through whatever clothing was available to fit their enlarged frames.

"Well, sister," said a 6 foot tall, E-cup Motoko Aoyama, "it's as bad as I've feared."

"What's the verdict, little sister?" replied Tsuruko, who couldn't help but note the irony of what she had just referred to her younger sister as.  By this point, there was nothing ‘little' about either of the Aoyama women.

"Six foot, two inches," declared Motoko with worry in her voice.  As far as Tsuruko's breast size was concerned, she was at least an E-cup if not an F-cup.  Such a revelation was shocking enough as it was, though it certainly explained the tightness in both sisters' clothing that morning.

"I must say, I wasn't expecting the morning to turn out like this," commented Tsuruko.  "It's not everyday that a person shoots up several inches after sleeping off a night of merriment."

"You can say that again," commented Motoko, still shocked at her own height increase.  Being 5'9" was tall enough as far as standards in Japan were concerned.  Now at 6 feet even, Motoko would only stand out even more so than before.  Though she felt that she shouldn't declare "woe is me" too much as her older sister was even taller than her.  In any case, both Aoyama women, already tall enough before last night, were now even taller and more developed.  It was as alarming as it was amazing.

"Thankfully much of our clothing is relatively loose," commented Motoko regarding the traditional hakamas the sisters regularly wore.  "Though our arms and legs will unfortunately stick out somewhat."

"That's assuming we don't grow more, dear sister," responded Tsuruko.  "I certainly consider myself tall enough as it is, though if we end up becoming even larger than we are now, then our clothing selection is bound to become quite limited.  Even a hakama won't suffice if we enlarge much more than we have now."

"You have a point," muttered Motoko.  She was trying to wrap her mind around just how this sudden change had occurred.  It obviously had something to do with last night in the baths, that much was clear.  Probably connected with that sudden blissful, euphoric wave that affected all the other girls alongside the two of them.  If that was the case, then there was a high likelihood that the other girls had experienced similar effects as well.  Both sisters only hoped that the other girls were taking this sudden change as well as they were.

"Uhhh...my head," muttered Kitsune.  Clearly she had done more drinking than she should have last night.  Though she was no stranger to hangovers, she wasn't one to learn her lesson when it came to alcohol and letting loose.  While she swore that she would let up on her drinking somewhat and put aside money to help out with her share of the rent, Kitsune felt that it was only proper to commemorate the arrival of four new tenants at the Hinata House.  That was why she brought out two bottles of sake that night, hoping there would be enough to go around for the older women gathered there.   It may have been a smart move on her part, as the bottles ended up being exhausted by the end of the night, but the hangover that lingered served as a hard reminder for the fox-eyed girl to mind her overall alcohol intake.

"You too, Kitsune?" replied Mutsumi, holding her own head.  While the Okinawan girl couldn't pound shots as much as Kitsune could by comparison, she had her fair share of shots during the night - a good six or seven from what she could remember.

"Afraid so, honey." muttered Kitsune in response.  "I figured I was gonna pay for it in the mornin' alright, but I just wanted to cut loose and have some fun with all my girlfriends, ya know?"  By this point, Kitsune was heading over to the mini-fridge in her room for a bottle of water.  Upon opening the door and reaching in, she held two bottles in one hand.  While she was still under the lingering effects of the hangover, she couldn't help but feel that something was slightly off.  Did the bottles feel a bit...smaller?

"You want one, Mu-chan?" asked Kitsune, motioning to the water bottles in her hand.

"Sure," responded Mutsumi, "thank you, Ki-chan.  Goodness knows I need the hydration."

Upon cracking open the water bottles, both women downed them in seconds, emptying the plastic bottles of all their water like it was nothing.

"Hmm...that hardly felt like much," commented Kitsune, "I'm gonna have one more.  Want another?"

"Yes, please." replied Mutsumi.  "I'm still rather parched.  My throat still feels pretty dry."

After downing another pair of water bottles in the same amount of time, both women were temporarily satisfied that their bodies were momentarily hydrated after the amount of drinking each of them had partaken in.  They then proceeded to find something to wear, when sure enough, the same problem that was befalling all the other women in Hinata House had made itself known to them.

"Rgh...umf...dammit.  It's lookin' like...mphf...nothin'...wants to...fit." grunted Kitsune.  Sure enough, the act of putting on ANY article of clothing was becoming something of a chore.  Whether it was her bras, her panties, her shirts, socks, or pants, every piece of clothing felt as though it was a size or two smaller than it should be.  That in itself was odd enough, given that her clothing had fit her just fine the day before.  It's not like everything just magically shrunk after a run through the washer and dryer.  What made things even more shocking was that Mutsumi appeared to be in the same boat as Kitsune.

"How are you faring, Mu-chan?" asked Kitsune.

"Afraid to say, no better, Ki-chan." responded the soft-hearted Okinawan.  Sure enough, not a single article of clothing Mutsumi brought along with her had fit her as well.

"I don't understand," said Mutsumi as she struggled with her bra and panties, which were digging into her tremendous bosom and the supple flesh all around her waist.  "I could have sworn these clothes fit me perfectly.  I've had them for years.  What could have caused them to shrink, I wonder."

"Mutsumi," said Kitsune with a more serious tone in her voice, "I get the feeling our clothes haven't shrunken."

"Well, they must have, Ki-chan," Mutsumi answered back, "how else could it be that they don't fit?"

"If the clothing hasn't shrunken' one lil' bit, which I'm thinkin' is the case, then there's only one other alternative explanation," said Kitsune.

"You don't mean..." the trepidation in Mutsumi's voice was all too apparent.

"Only one way to find out." responded Kitsune.  "Let's head over to Naru's room.  If I remember right, she's got a measurin' tape.  Figure we might as well set the record straight on my hunch."

After taking some clean bedsheets which were available in Kitsune's room to serve as makeshit togas, both girls made their way from Kitsune's dorm room over towards Naru's.  They were fortunate enough not to bump into anyone else, especially Keitaro as they figured he would be rather flabbergasted at the sight of two buxom young women wearing nothing but white bedsheets for clothing.

A moment later, both girls arrived at Naru's bedroom, hoping that she would be in as they didn't want to have to explain why they were standing in the hallways wearing nothing but bedsheets.  Fortunately for them, there was a response a moment later.

"Who is it?" said Naru on the other side.

"It's me, Sugar," answered Kitsune.  "Mutsumi and I need a moment, if you can spare."  Kitsune could only hope that Naru wouldn't freak out too much at the sight of the two of them wearing nothing but sheets as she opened her bedroom door.

"Uhh...sure thing, just give me a second.  Mei's in here with me, just so you know."  There seemed to be some degree of trepidation within Naru's voice from what Mutsumi and Kitsune could discern.

After a momentary pause, the door cracked open and lo and behold were the sight of both Naru and her younger sister standing before Kitsune and Mutsumi.  The sight of each pair upon the other was quite something.  Before Naru and Mei were Kitsune and Mutsumi wearing nothing but white bedsheets which hugged their rather ample curves, particularly their generous bosoms, which appeared to be larger than Naru recalled from the few times she took a good peak at them.  Likewise, before Mutsumi and Kitsune were Mei and Naru, wearing clothing that was clearly undersized for their figures, hugging them to the point that their clothing looked as if it was practically painted on them.  Each girl couldn't help but stare and even admire how the other girl's choice of clothing hugged her body so very tightly, accentuating her curves, cleavage, the swell of her bosom, the mix of plumpness and muscle in her hips, thighs, abdomen, shoulders, and other parts of her body.  It was a sort of gathering of impromptu models standing right outside the entrance of Naru's bedroom.

"You too, huh?" said Naru and Kitsune to one another at the same time.  After a momentary pause at the gravity of the situation, Naru beckoned Kitsune and Mutsumi into her room.

The incoming pair gave the rundown on their clothing situation, to which Naru and Mei echoed similar similarities regarding their wardrobe malfunctions.  It was then that Kitsune asked Naru for her measuring tape, to which Naru complied with her best friend's request.  Upon fetching it, Naru made pencil marks for both Kitsune and Mutsumi to gauge what their heights were currently.

Sure enough, Kitsune's hypothesis was correct:  5'9" for Kitsune, 5'8" for Mutsumi.  Little wonder their clothing was straining to fit them.

"Well, while we're here," said Kitsune with a sober mindset after learning of her sudden height increase, "might as well take our other measurements, if ya don't mind."  The meaning wasn't lost upon Naru or Mei.  After some fiddling with the measuring tape, the new breast sizes were in as well:  Kitsune was sporting either a heavy E-cup or an F-cup while Mutsumi was definitely in F-cup territory.  That revelation alone certainly brought a momentary silence of shock upon all the women standing in Naru's room.

"Well," said Naru, "hopefully the others are taking this sudden change as well as can be."  In that moment, she pondered how someone delicate like Shinobu would take such a dramatic size increase, given that EVERYONE was in the baths from that episode last night.

"Oh no," said Shinobu in a very worried tone of voice, "this is bad, Nyamo.  This is really, really bad."

The dainty little girl had come to find that her body was not quite as dainty as it was the previous night.  While Shinobu was blossoming into a lovely young lady, her curves and bosom had shown modest gains compared to other girls.  Before last night, Shinobu was sporting B-cup breasts and was a mere 5'2" in height.  Now after the events of last night, those stats on her figure were highly outdated.

The 5'6" girl sporting C-cup breasts was now on the verge of tears as she talked to her roommate.  Given how none of her clothing had fit her comfortably, Shinobu had deduced that something was terribly wrong.

Nyamo, also standing at 5'6" and sporting either heavy C-cups or modest D-cups, simply stood there as Shinobu fretted over their current situation, especially their lack of a proper wardrobe.

"What are we going to do?" said Shinobu, worry growing in her face and in her voice.  If someone were to come across the two of them, clearly something would be off.  If it wasn't the serious wardrobe malfunction, then it would be the increase in height and the amplified breasts and waistlines that the girls were sporting.  At that moment, Shinobu was racked with worry over how she was going to explain her sudden sprouting up to others, especially Keitaro.  The last thing she wanted to do was alarm him or make him panic at realizing that she was practically eye-level with her crush.  The very idea of such a thing felt emotionally suffocating to Shinobu.

"Sooner or later, someone is going to either run into us or ask if we're okay if we don't come out of here.  And when that happens, they'll see us and then we'll have to explain ourselves.  And what are we gonna say?  What'll we do?  They'll probably call the police or maybe some scientists and have us taken away to be studied.  And what if we keep growing like this?  What are we gonna do?  How are we gonna explain all of this?"  The worry in Shinobu's voice was reaching a fever pitch, and the tears in her eyes were all too apparent.  The poor girl was nearing a complete emotional breakdown over this morning's discovery, so Nyamo simply decided to take action.

As Shinobu was rambling over their predicament, Nyamo walked over to her roommate and tightly embraced her, wrapping her arms around Shinobu's torso and holding her firmly, yet gently in the process.  Shinobu was temporarily taken back by the gesture, but she quickly returned the hug, squeezing Nyamo tightly and sobbing into her shoulder as the tears began running down her cheeks

"It'll be okay," whispered Nyamo into Shinobu's ear.  "We'll figure it out.  Please don't cry."  Nyamo always had a way with words, getting to the point in a very humble and soothing way.

Once Shinobu calmed down, she wiped her eyes, took a few deep breaths, and composed herself before continuing.

"Thank you, Nyamo," Shinobu said with a smile.  "You always seem to have just the right thing to say when needed."  Nyamo simply returned the smile with one of her own.

"In any case," resumed Shinobu, "we're going to have to come out of here eventually, so we might as well do it sooner than later.  And as far as what happened to us, I think I have an idea as to what caused all of this.  It must have something to do with what we...well, Sarah...took out of Kaolla's room.  I just don't know how it ended up getting into the baths.  But it MUST have made it in there somehow, right?"

Nyamo merely nodded her head in agreement.  Both girls figured that the bottle taken from Kaolla's dorm room somehow made its way into the hot springs and affected the two of them, and probably the other girls as well if their reactions in the baths last night was any indicator.  In order to get to the bottom of what occurred, they figured that the best way was to bring it up with the one who created the contents of that bottle.

"So," said a 6'2", E-cup Amalla Su, "an experimental growth hormone, huh?"

"That's correct," responded a 5'5", C-cup Kaolla Su.  "It's something I've been dabbling with in my free time between making advancements in robotics, electrical engineering, and computer sciences.  While biology isn't necessarily my forte, I thought I'd tinker with it whenever I had free time."

"To what end?" inquired Amalla.

"A few applications came to mind," elaborated Su.  "My first intention was to increase the overall size of livestock, wildlife, and other animals which serve as food sources.  The idea was that if I could increase the size of cattle, fish, poultry, and whatever else is part of the human diet, then I could do my part to curve or even eliminate hunger outbreaks, starvation, and famine in a few years.  I also considered tweaking the formula to allow for it to affect plant life and vegetation, thus resulting in larger crop yields."

"Interesting," muttered Amalla, marveling at the genius of her younger sister.  "And you say this was your third batch?"

"Indeed," continued Kaolla.  "The first two batches had less than satisfactory results.  I experimented on small animals, mainly guinea pigs, lizards, and insects to see how the formula would work.  Needless to say, there was no significant increase in size, and thus I came up with batch number 3.  I suppose the old saying holds true:  ‘Third time's the charm' and all that."

"I suppose so," said Amalla with a grin.  Even though her clothing had been rather tight since waking up, she wasn't particularly upset with the notion of being without it.  Given Amalla's free spirit, she had no real qualms about walking around the house naked, at least when she was back home in Molmol.  Given that Hinata House was her home for the time being, she carried the same mindset with her here.

"So how did your formula end up in the baths?" asked Amalla.

"I have a theory, but it's not quite complete," responded Kaolla.  "I'm guessing that Sarah, Shinobu, Mei, and Nyamo were here in my room exploring while we were away.  Then one of them - most likely Sarah - came upon the formula and then the group of them left.  Sometime between them leaving and all of us entering the baths, the bottle of formula somehow made its way into the bath water.  The rest is pretty self explanatory."

"About your formula," inquired Amalla, "can it enter the body in a number of ways?"

"Yes.  Injected, ingested, absorbed through the skin, inhaled in a gaseous form.  I designed it to be easy to interact with whatever organism came into contact with it.  That was my intention anyway, and I must say, it worked even better than I anticipated.  I was expecting modest results over the course of several days, not...well, this."

On those last three words, Kaolla was gesturing to her own body alongside her sisters.  By this point, the younger Su sister had a form similar to her ‘adult form' whenever the red moon showed up.  Her face was more matured looking, her bosom was enhanced, her hips were wider, her muscles more defined (especially along her abdomen, thighs, and buttocks), her lips more pronounced, her neck longer and more slender.  In short, Kaolla looked as though she had accelerated in age by two or three years, having the form of a girl who looked around 18 or 19 years old.  And all of this was in the span of one night.

For her part, Amalla was certainly enjoying the enhancements in her body as well.  She was no stranger to being tall, and now that she was more than 6 feet in height, the very notion brought a minor tingle to both her spine and her loins.  She couldn't wait to see Keitaro's reaction to the new Amalla the next time she saw him.  Beforehand, she had about a three inch difference in height the last time they met.  Now that she was more than half a foot in height compared to him, she was just dying to see how he'd respond to the larger, more seductive Amalla.

"In any case, I'd better get to work on some things," said Kaolla.

"What kind of things?" asked Amalla.

"Clothing for one.  Given our increase in size, I'll need to start making some clothing that wel can all wear.  Fortunately, I have a machine that can do the job for us.  Basically, I just need to input the right dimensions and it'll print out whatever article of clothing desired.  Skirts, shirts, pants, you name it.  I figure with thirteen women having an overnight growth spurt, we'll need to make adjustments soon before we start bursting out of our clothes."

"You've thought of everything, haven't you, Kaolla?" said Amalla with a smirk.

"Well...not everything, big sister," responded Kaolla with her own smirk.  "There's also the matter of food.  With all of us getting bigger, we're going to need more calories at our larger sizes.  We can shop for more groceries, but that's only a temporary measure, especially if our rate of growth is in line with my calculations."

"I think I can help relieve some of that," responded Amalla.  "Let me make a quick call back home.  I can have some food special-ordered from Molmol and have it shipped here right away.  Think of it as my way of chipping in around here.  As a matter of fact, I'll have some servants brought in as well."

"For food preparation?" asked Kaolla.

"Among other things, yes," said Amalla.  "I can think of a number of tasks for them to aid in so as to take the weight off of Mr. Urashima's shoulders and make life easier for him.  And given that I'm royalty, they'll only be too happy to serve me during my time here."

"When do you think the food and servants would arrive?"

"If I make the call right now, I'd say a day from now.  Two at the most.  It's all thanks to your mecha-Tama transportation craft, remember?  Molmol now sports a good sized fleet of your flying mecha-Tamas, so delivering supplies and people is but a minor chore now."

"Oh right, I nearly forgot about those.  I haven't tinkered with the mecha-Tamas for some time, so it must have slipped my mind."  Even if she was a genius, Kaolla did tend to forget the occasional project she was working on from time to time.

"Well then, shall we be off?" asked Amalla.

"What do you mean?" asked Kaolla with unsure curiosity.

"Well, I figure we're going to have to leave your room eventually and get something to eat.  So what say we head downstairs and make some breakfast?  As a matter of fact, I'm going to go and round up everyone else so we can all eat together like one big, happy family."

"When you say ‘everyone else,' you mean all the other girls, right?"

"When I say ‘everyone else,' I mean ‘everyone else,' so that means all the other girls AND Keitaro."  By this point, Amalla had a mischievous grin on her face.  Kaolla knew that her older sister was up to something.

"Amalla," warned Kaolla, "I get being up front with all the other women about last night and helping to ease them into what's happening to them, but you need to take things easy with Keitaro.  He's obviously going to be alarmed by what's happening to us the moment he sees any one of us.  So I insist that you don't alarm him or make him uncomfortable."

"Oh Kaolla," sighed Amalla, "have a little faith in me.  I'm not planning to make Keitaro uncomfortable in any way whatsoever.  Quite the opposite, in fact.  If you want this little harem of yours to take flight, then we'll need to get the central pillar to get used to being surrounded by a flower garden of female beauties.  Trust me, I plan to drown Keitaro in an ocean of love, affection and female companionship when all is said and done, and the sooner I make contact with him, the sooner we can get this show on the road."

With that, Amalla left the bedroom, making her way towards her fellow dorm neighbors with the intent to get the ‘harem plan' she and Kaolla talked about under way.
