“Miss Yuyuko… Miss Yuyuko…! I can’t finish cleaning if you don’t… Oh, forget it.”


Youmu Konpaku, personal servant to Yuyuko Saigyouji and gardener of Hakugyokurou, quickly learned from experience that attempting to comfortably rouse her mistress when she was having an afternoon nap after some snacks was like trying to wake the dead. Her ever-present phantom half drooped as she stood over her lazy mistress with her hands on her hips, being yet again unable to bring herself to shake her awake or perhaps give her a good kick for once.


Instead she watched Yuyuko’s chest gently rise and fall, despite the fact that a ghost had no need for any such motion. It was merely that lingering habit that transfixed Youmu, and certainly not just how much her chest pushed out her kimono, and how perfectly shapely they were, or how you could see them shake even through the thick fabric when she moved. And it was definitely not that she was jealous of them in any way, she told herself as she tore her eyes away to go take a well-deserved break of her own.


How could she be? They seemed terribly inconvenient, like they’d get in the way all of the time, she told herself this as she stomped down the hallway down to her bedroom. Youmu was sure that if she had them, which she wasn’t saying she wished she did, she’d get sick of them immediately. People like Yuyuko, or Yukari, or that green-haired Moriya shrine maiden were truly living with a terrible inconvenience, she bet that they would secretly admit they’d get rid of them if they had the chance.


Of course, Youmu pursed her lips as she slammed the tatami door to her room shut, there was no way to know for sure. Not without experiencing it herself first-hand. Then, she could settle the matter once and for all. You know, just to see how she felt about it. But she couldn’t exactly grow giant breasts on the spot, and she didn’t exactly have something conveniently round that she could stuff her bra with. Something large, round, soft, and could be squeezed into just the right shape…


Youmu’s phantom discreetly floated out of her field of view, as if it contained her more sensible thoughts and wanted nothing to do with this idea. Unfortunately, being part of Youmu, she noticed this immediately and snatched it out of the air, unbuttoning her blouse and shoving the resisting spirit into it, where it filled out the top to its breaking point, the buttons straining to contain the semi-solid entity. After managing to force her buttons together around it, she turned to pose in the mirror, putting on her sexiest pose and thrusting her hips out to emphasise it.


It wasn’t a bad look for her, Youmu decided, striking another pose and admiring herself in the mirror. Sure, she couldn’t see her feet past them, what a figure! Youmu knew that she’d wear it best, much better than Yuyuko. If she could see her now and compare them, she was sure she’d say-


“Oh my, Youmu, when did this happen?”


Youmu froze and slowly turned around, seeing a sleepy-looking Yuyuko standing in her doorway, watching her mid-pose. Initially she was embarrassed and ready to stammer out an extremely awkward excuse, only to burst out laughing at the sight of Yuyuko’s genuinely confused face, as if she believed that Youmu had genuinely grown gigantic breasts while she’d been asleep. After a few moments of looking dazed, Yuyuko joined in and started gently chuckling, going along with the mood.


“Nothing happened, Miss Yuyuko!” Youmu giggled, returning to a more relaxed stance. “I just suddenly wanted to know what it’d be like if I were in your… position, for a bit. So I could, uh, empathise with you a little more.”



“I see. You do look quite nice with a more generous chest.” Yuyuko said kindly. “By the way, how did you do it? I hope you didn’t skip any steps and not learn how to turn yourself back, unless you’d rather stay that way.”


“I didn’t learn how to do anything, Miss Yuyuko.” Youmu’s lingering embarrassment over being caught was dispelled by how slow on the uptake her ditzy employer seemed to be, and gestured at her top. “It’s just my phantom under here.”


“Really?” Yuyuko once again seemed confused. “Then what’s it doing over there?”



Youmu slowly turned her head to see her phantom floating by her side, making a motion that seemed like shrugging. It had been practically suffocating in there, and had promptly turned incorporeal and escaped. But if it was here, then what was in there?



Youmu, slowly and delicately as if there were a bomb hiding under there, unbuttoned the top of her blouse, revealing more and more milky cleavage that seemed to keep going and going forever. She felt like she could have fit her entire hand in there by the time she ran out of buttons she could undo without letting the whole thing flop out, and a tightness she had felt suddenly felt completely relieved. She nearly lurched forward from the sudden acknowledgement of the sheer weight of two breasts nearly the size of her head, with puffy nipples visibly poking through the thin fabric of her blouse.


“W-w-wh, wha-” Youmu stammered, her face quickly flushing a brighter red than the Hakurei shrine maiden’s clothes. “What is this!? Why are they so big all of a sudden!?”


“Because of the spell you used to make them bigger, I would assume.” Yuyuko said, making the most obvious assumption.


“I didn’t do anything! 



“Well, would you like some extra allowance to go buy yourself a new bra?” Yuyuko said without any hint of mocking in her voice whatsoever as she watched Youmu practically run around the room in panic looking for something to blame, her newly acquired massive breasts bouncing with each stride. “I can lend you one of mine, but I don’t think it’ll quite fit…”



“Are you sure you’ll be alright, Youmu?” Yuyuko asked as Youmu somehow managed to do up her top without any of the buttons snapping off, her breasts now somewhat uncomfortable nestled in Yuyuko’s ever so slightly too cramped bra. Once Yuyuko had been able to calm her down to a certain degree, the reality of letting them hang without support kicked in, and Youmu reluctantly accepted her support.



“I’ll be fine!” Youmu said, attempting to regain her composure. “Preparing your lunch won’t be a problem, or any of my other duties!”


“It’s alright to admit that you forgot the spell to undo it-”



“For the last time Miss Yuyuko, I did not do this to myself on purpose!” Youmu’s breasts heaved in indignation, her buttons holding on for dear life. “And if I did, I’d know exactly how to undo it! Which is proof that I didn’t do it intentionally!”


“If you say so…”


Youmu ignored the fact that Yuyuko still looked unconvinced and stormed off, doing her best to maintain her balance with the two new weights hanging from her chest. It was impossible to ignore their heft and bounce with each step, even without the fact that they were perpetually in her peripheral vision, drawing her gaze until they consumed her full attention, causing her to nearly walk chest-first into a wall. She attempted to compensate by crossing her arms under them for support, which did relieve her back a bit as she made her way to the kitchen, stubbornly determined to let the rest of her day play out as usual.


Perhaps, Youmu reasoned, they would simply vanish as quickly as they came. A temporary prank played on her, and one that would go away if whoever did it to her got bored. Refusing to let herself be beaten by her assumed assailant or her own body, Youmu reached her destination and got to work.


It was there that she suffered her first trial: moving around with her new boobs in a limited space. Her chest stopped drawers from being fully opened, and she found them resting on the chopping block she intended to cut ingredients on. She had to step back and lean awkwardly to get them out of the way, only to find the weight of gravity to be a serious burden in her bent over position. Gnashing her teeth at the fact that she couldn’t even cut vegetables without squishing her boobs together, she settled for pushing the chopping block forward, resting her boobs on the bench to relieve herself, and settle for simple onigiri that she could do with minimal effort. Lacking a lifetime of experience on how to best carry herself, her massive chest was nothing more than two big pillows that seemed to get in the way of everything she wanted to do.



Wondering if this was why Yuyuko was such a terrible chef, she left the snacks out for her and tried to distract herself with her training regime, knowing that the repetitive sword drills she performed on a daily basis never failed to soothe her mind.


Sadly, the comfort and reliability of her training would be shattered by them too. Everything went fairly smoothly when she raised her arms until her breasts, leaping upwards from the momentum, inevitably fell back down and threw off her balance with their heavy bounce, even with Yuyuko’s rather tight bra trying to contain them. Then when she brought her arms down they squished together, and the sensation left her blushing and distracted.


“Yuyuko never mentioned that these things would be such a nuisance…!” Youmu complained as she kept swinging, making rather inelegant motions as she tried to work around them. Everything was distracting, least of all the fact that it felt just a little good every time they were squashed or shaken. She tried to clear her mind, but with each swing her face got a little redder, until she had nothing but lewd thoughts, her swings getting faster and faster until they lost all technique whatsoever.


Her wild swings came to a sudden halt, her chest taking several seconds to stop wobbling afterwards as Youmu realised that if she went any further, what she was doing could no longer be described as training, and was nothing more than jiggling and squeezing her breasts just so she could feel her erect nipples rub through her bra. The thought left her with deep shame, and she scanned the yard, hoping desperately that nobody was watching her.


Clearly, Youmu thought as she tried to settle herself down, ignoring the problem just wasn’t going to work. Just what on earth could have caused it? Magic? A prankster god? Some sort of secret ability of half-phantoms that was unknown to her up until this point? How long was she going to be stuck like this? Forever? She was mortified at the idea of somebody besides Yuyuko seeing her like this, which was inevitable if she couldn’t find a solution fast.


Wanting to at least end it with something resembling normal practice, Youmu cleared her mind, widened her arms, and took a final powerful swing, the first that felt like a normal one unobstructed by her breasts. Unfortunately, her button had been pushed past its limit and finally gave up the ghost, exploding off of her shirt and ricocheting off a nearby pillar with a lound ping.


Flushed bright red, Youmu reluctantly sheathed her sword. She had to find help for this, and fast! But who could she possibly go to for help…?



“And what do I owe the honour, Miss Konpaku?” Alice Margatroid, seven-colour puppeteer and reclusive magician asked the young woman who knocked on her door for perhaps the first time ever, looking extremely paranoid and currently wearing a heavy cloak that covered her from neck down to her ankles. She was also sweating, both from the obvious paranoia on her face and the fact that it was far too hot for such a thick mantle. The two knew each other as acquaintances and had spoken from time to time, but neither would call each other friends, and Alice knew that if she was being approached directly, it was likely for extremely shifty reasons. Very few willingly went out of their way to visit her, save for a certain other blonde magician who enjoyed her company far too much.


“Can we speak inside?” Youmu said nervously, constantly looking over her shoulder for anybody who might be following her, causing a shake visible even through the cloak she was attempting to obscure her new body with.


“Whatever this is, I don’t think I want to get involved.” Alice cut straight to the point and attempted to close the door, only to find Youmu’s boot placed firmly in the way.


“If I could just have… a moment of your time…” Youmu said, seizing the door and forcing it open. Unfortunately for the extremely out of shape magician, the trained swordsman did this with ease, causing Alice to sigh and politely invite her in.


“And what exactly am I looking at?”



“I should think it’s quite self-evident.” Youmu said very politely with gritted teeth. “I was hoping you could share some theories about why this happened.”



Youmu didn’t point at the problem, nor did she break eye contact, and neither did Alice.


“Puberty, perhaps?” Alice’s lips curved ever so slightly upwards, and Youmu began to wish she brought her sword.


“It just did this on its own before I knew what was happening! In an instant! There wasn’t even a poof, or a vavoom, it was just like that!” Youmu almost babbled out, grabbing her chest and pushing it together, forcing Alice to blush and force her gaze elsewhere.


“I, um, see.” Alice cleared her throat. “You didn’t cast a spell or anything and forgot to learn how to undo it?”


“Of course not! It’s not magic or a potion or anything! It just did this! You’re what, two hundred years old? Three hundred?” Youmu guessed wildly at the former human’s age. “Surely you’ve seen this happen to somebody at least once, right? This is just a normal thing that happens to people every now and then, right?”


“I, erm, can’t say that I have.” Alice sipped at her tea to try to regain some composure. “If I might ask why you chose me to help you? Surely there must be others who are more qualified than a practitioner of magic such as myself. If you believe it’s a natural phenomenon, Eientei seems like a more logical first pick-”



“I can’t go there, there’s no way they can keep a secret. The rabbits love to gossip, and they’d probably dissect me for science anyway.” Youmu bit her lips, wild paranoia in her eyes. “Miss Yukari might know, but she’d use this to blackmail me for the rest of my life. I can’t go to the Scarlet Devil Mansion, I don’t need to give that maid more ammunition and I doubt that anemic magician would help… I don’t think the Hakurei shrine maiden would know what to do, although maybe I could ask that hermit who keeps showing up there… No, she’d just tell me I should reduce my worldly desire… I can’t be seen near the village, I’d be on the front page of that Tengu newspaper-”


“I think I get the point.” Alice politely held up her hand for her to stop. She was glad that Youmu was so caught up in her rambling that she didn’t notice that Alice had been finding it extremely difficult to tear her eyes away from that bust, it was to huge and round and squeezable, it was practically busting out of her clothes… No, she wasn’t jealous or anything, she didn’t want it on herself, she just wanted to touch it a little-


“You’ve got to help me! I can barely swing a sword with these things in the way!” Youmu begged, and Alice tried her best to maintain eye contact again.


“Since you’re already here, I suppose I’ll have to do my best.” Alice coughed, and tried not to get distracted as she gave herself an excuse to stare at Youmu’s massive boobs for a few seconds. Examining them for as long as she could without getting transfixed, Alice eventually gave her professional opinion.


“I can’t detect any magic radiating from or contained within your, um, chest. If it’s the result of a spell there should be some kind of signature or lingering energy, but this seems natural from my perspective” Alice wished she wasn’t so pale, as it made her blush much easier to spot. “I don’t suppose you’ve been praying to any wish-granting gods lately, have you?”



“I have most certainly not!” Youmu asserted awkwardly. “You know what, let’s stop worrying about where it came from, it’d just be easier to find out how to undo it by any means necessary! Surely you know a shrinking spell or two?”


“Not for shrinking specifically boobs.” Alice’s elegance slipped for a moment. “Even if we tried shrinking just part of your body, it wouldn’t look or feel right, and it’d be bad for your health. Imagine shrinking your ribcage and everything within it without shrinking the rest of you.”



“Alright, let’s not try shrinking then.” Youmu hurried to say. “Come on, surely there’s somebody who magically wanted to improve their figure a bit, can’t you find one of those and, you know, work backwards from there?”



“I know of them but I’ve never dabbled in them myself. The problem with spells designed by the user to improve is that they usually don’t think anybody would want to undo it afterwards-”


There was a loud knocking sound coming from the next room over that interrupted the two, Youmu freezing up.


“Hey, Alice! You left your window locked today! Let me in!”


“Just a moment! And use the door next time!” Alice called back at her usual visitor, Youmu looking ready to panic.


“Actually, I’ll come to you!” Marisa called back, heading for the window of Alice’s living room. Alice, well familiar with how fast she moved, knew that there was no time for Youmu to escape.


“I’ll hide you, just don’t say a word!” She leapt from her seat and grabbed Youmu, opening a large cabinet filled with various coats and shoving her into it before she could suggest any alternatives. She slammed the door shut, or at least tried to, finding it halted by some sort of soft, pillowy object. She pushed harder and locked it, ignoring Youmu’s gasps of distress.


“Miss Alice? I can’t breathe! It’s too tight!” Youmu wheezed with her new breasts pressed almost completely flat, Alice quickly fixing her hair and trying to play it cool before Marisa invaded her home.


“Suck it up!” She advised, both figuratively and literally, then put on her best poker face and calmly walked towards the window. “Just keep quiet, she usually leaves after an hour or two!”


Youmu heard a click and realised that she had been locked in, the only way to stop her from pushing the door open. She heard Marisa’s loud, cheerful voice as she arrived, trying to hide her own breathing as she heard her sit down at the table right in front of them, obliviously babbling away about whatever magical whim had crossed her mind that day.


Youmu barely followed the conversation, too distracted by the tightness she felt from being so compressed. She wriggled around, trying to quietly unsmoosh her breasts, but only succeeded in rubbing them against the aged wood, biting her lip and desperately trying to avoid gasping in pleasure. Once every thirty seconds or so she couldn’t help but think that she’d have been quite comfortable in there, if she’d done this a single day sooner…


She remained like this for almost an hour, as Alice unsuccessfully tried to get Marisa to leave, eventually serving her cup after cup of tea until finally Marisa was forced to excuse herself. Alice rushed to the closet the moment Marisa left, unlocked it and nearly being bowled over by a completely red faced and sweaty Youmu collapsing out of it. Feeling like she was breathing fresh air for the first time, Youmu had to be directed to the window and helped out by Alice, promising that she’d try to make up for her treatment another day.



Youmu felt about ready to collapse by the time she went to bed that night, letting her heavy breasts press down on her as she was splayed out on her back on her futon. Her pajamas were showing off a hefty amount of cleavage, as she couldn’t pull them shut, but she was more than happy to let them breathe after her experience at Alice’s place.


Youmu wished she’d never even entertained the thought of wondering what it’d be like if she had breasts like Yuyuko’s. They were big, heavy, and just go in the way of everything whether she was training, cleaning, or cooking. They had no upsides, besides that they gave her an ideal figure, they were soft and felt nice, she could brag about having possibly the biggest boobs in Gensoukyo regardless of how she got them, and they made her look very mature, at least in her own opinion.


There was only one problem: she couldn’t help but feel that her proportions were a bit lopsided. Having an enormous chest gave her a certain maturity, but her hips and butt were the same as ever. It certainly wouldn’t hurt her to have a little counterbalance, and give herself more of an hourglass. Just for consistency. She knew she wasn’t the tallest, so thicker thighs and larger hips were a must. Perhaps whatever had done this to her could be considerate and add to those too?


Youmu soon drifted off, not considering at all that perhaps the reason why they appeared in the first place was because no matter how inconvenient they were or how much she complained out loud or even to herself, she truly, deeply wanted them…
