“And of the many fertility gods in Korean culture, what are ones you can find in stone form in the south?” Hyejin asked the class of twenty-odd Korean schoolgirls as Jenny slipped in through the classroom door.

They all started giggling, almost in unison. These girls were all at least 18 years old, and yet as soon as a teacher discussed anything even remotely sexual, they dissolved into giggles. Jenny couldn’t help but laugh herself, as Hyejin rolled her eyes.

One hand snaked into the air. All the girls in the class were dressed in identical Korean school uniform of white blouses and grey skirts, but Minsuh still stood out from the pack. She was stunningly pretty, with perfect, shoulder-length hair, and a devastatingly cute smile.

“They’re called dol hareubang, Miss Ji-Min.” She smiled that smile, and Jenny could feel her heart skip a beat. Hyejin seemed a little flustered herself, but Jenny caught her eye, and they both grinned ever so slightly, and relaxed.

Just then, the bell rang to signal the end of the class and the girls began to pack up their things and file out. Jenny went up to speak to Hyejin, but as she did, Minsuh approached them.

“I just wanted to say, that was a great lesson, Miss Ji-Min. Thank you.” She bowed her head slightly, and hurried out.

Jenny raised an eyebrow at Hyejin, who looked as surprised as she was.

“Must’ve been a good one”, Jenny observed, “and exactly what I wanted to talk to you about.”

“Oh?” Replied Hyejin.

Both ladies were in their late 20s, and were experienced teachers, but Jenny specialised in research, and that was what she was here to discuss. She’d come all the way from the States to speak to the most prominent experts in South Korean mythology for a paper she was working on, and Hyejin Ji-Min was about as a good an expert as you could ask for.

They’d both been at the school for months, Jenny teaching to help pay the bills while she worked on her research, and they’d become close. There was a lot of touching and closeness at an all-girl’s school in Korea – among the pupils as well as the faculty – and Jenny was constantly trying to avoid thinking the things she did about Hyejin – she was here to work, after all. The last thing she wanted was to be distracted by an admittedly very pretty and incredibly intelligent Korean teacher with a pretty devastating smile of her own.

Jenny found herself admiring Hyejin’s immaculate black bob of hair, perfectly made-up Korean features and her slim, athletic physique, tucked into her black pants and white blouse. As an American, it constantly surprised her, even now, how almost universally slender Koreans were – it made her feel positively obese. She wasn’t – she was a pretty, slim, redheaded American with a sweet grin and an endearingly dorky demeanor – but it was hard to feel thin as an American in Asia, and she’d pretty much got used to the fact that she’d generally be the largest in the room. At least it meant she had bigger boobs than everyone else. They were small 32Cs, and she had to keep them respectfully covered, but at least it was something.

“Hyejin…I think I’ve found her.”

Hyejin uncrossed her legs and span on her chair to face Jenny.

“You’re sure?”

Jenny pulled out a large, leather-bound book from her bag and flipped open the musty pages.

“The dol hareubang you were talking about earlier – the Tanma Chronicles always refers to the Jeju word ‘haruebang’, for grandfather. But there was a grandmother. The one I’ve been looking for.”

Jenny flipped over the page with a flourish, revealing a huge-busted, slim-figured young woman with long flowing hair drifting down her body, artfully covering up her nipples, but revealing massive areola around the very generous breasts. She certainly didn’t look like a grandmother.

“Mudang.” Jenny pointed, proudly.

“ ‘Mudang’, as in, ‘female shaman?’ ”

“Exactly. This could open up a whole new realm of research into Korean mythology. And I owe it all to you.”

Jenny smiled, and Hyejin couldn’t help but smile back. She’d grown very fond of this American with her sweet smile and generous figure, and while she’d been assisting her with the research, she couldn’t help but feel they were becoming more than friends. But professionalism had always prevailed.

“Wait, what’s this at the bottom?” Hyejin asked, looking at a thin line of text that crawled along the base of the page.

“Good spot”, Jenny responded. Hyejin beamed. “Looks like some kind of incantation. Let’s read it!”

“I’m not sure we should”, Hyejin countered, still glowing from the previous compliment, but Jenny was already going ahead, mouthing the words with surprising proficiency and speed, considering the language was centuries old. Hyejin had to marvel at how skilled her colleague had become.

And all of sudden Jenny had finished, the skies suddenly grew dark and the building started to shake.

“Jenny, what have you-”

The book began to writhe in Jenny’s hands, before leaping across the room to the far wall of the classroom. Both women watched, astonished.

The book lay held up on the wall, open at the double page with Mudang on it, shaking and vibrating at it lay splayed open there, held by some kind of force. Then, suddenly and gradually, the book started to increase in size, the illustrations on the paper growing in tandem. Jenny instinctively felt for Hyejin’s hand, and they held each other close as the room continued to dim.

As the building continued to shake, the book slowly grew until it was the size of the wall itself, the picture of Mudang completely lifesize.

And then, the lines and illustrations began to swirl and curl, and Mudang stepped out of the book.

The shaking of the building was loud at this point, but Jenny could still hear Hyejin’s sceams along with her own as a huge, tall, naked, incredibly busty women appeared at the other end of the classroom. Her long, lustrous dark hair poured over her stupendous body, her massive, full, pendulous breasts swinging in front of her, huge and firm on her slim body.

She was the embodiment of fertility, and as she moved across the classroom towards the terrified women, her breasts seemed to swell and bulge, riding high and full on her chest. They bounced gently as she strode towards them, and tiny dribbles of milk squeezed out of the end, trickling down her chest and running in mini-rivulets towards her pubic triangle. She was huge, and magnificent and terrible.

And then she stopped, right in the middle of the room, in all her busty, naked glory. Hyejin and Jenny stared at each other, eyes wide with fear, unable to do anything as Mudang spread her legs shoulder width, thrust her arms up into the sky, and bellowed, in a voice as ageless as time itself, the words that Jenny had read.

Bolts of pure energy fired out of Mudang in all directions. One hit Hyejin right in the chest, the other, Jenny. Bolts fired out the window into the faculty lounge on the lower floor, and bolts fired straight down into the girl’s dormitory, where all the 18-year olds stayed.

Jenny and Hyejin both were flung backwards into the wall where they were held, slightly above the ground, their chests heaving, both still holding hands. And as they writhed there, pinned against the wall, they felt their breasts starting to grow.

It was slow at first, but as they panted with panic, their heaving bosoms began to heave upwards considerably more than they sank back down. Jenny could feel a tightness in her chest, that she attributed to the intense fear she was experiencing, but it was more than that. Her breasts were actually, somehow, growing larger. She could feel her bra straps digging into her shoulders as her boobs slowly filled out, and filled up, she could only imagine in the same way that Mudang’s had – with more and more milk, as she experienced an onrush of fertility like she’d never known.

Jenny moaned and writhed, still pinned to the wall, as her chest got heavier and heavier. She realised she was still holding Hyejin’s hand, and clutched it tighter, feeling her colleague squeeze her back. Jenny’s loose blouse was tightening up as her breasts expanded, and her bra was starting to feel smaller and smaller around her swelling form. She looked down to see her formerly modest breasts bulging bigger and bigger into her tightening bra, which was already not up to the task of keeping her tits contained. She could see the tops of her boobs bubbling over the top of it as her blouse began to tighten further.

The buttons were starting to be pulled apart by the width of her boobs, and gaps were appearing between each button as her shirt was pulled tighter and tighter. She pulled the top of her blouse away from her chest, and gasped at how snug her bra was against her swelling tits. It was going to burst off at this rate!

She looked over at Hyejin, and her jaw dropped. Her friend was experiencing similar growth to Jenny, but it had clearly hit her harder. Her boobs were already a D or E cup, and were swelling out into her work shirt, as her two large mounds filled with milk, stuffing her shirt to the max already. Jenny realised Hyejin’s clothes would have much less give than her own, and as such would already be fit to burst, but then as she looked back at Hyejin’s tits compared to her own, she realised her friend was growing faster than she was – and that was saying something.

Looking down at her own tits, Jenny felt like she was packing two balloons under her blouse, balloons that were going to pop at any moment. Her tits felt so heavy and full! She longed to squeeze the nipples and fire out the massive streams of milk that were swelling her up bigger and fatter with every moment – the bigger she got, the more turned on she was starting to feel, and she could tell Hyejin was the same.

Her colleague was breathing in deeply through her nose, biting her bottom lip hard as her massive tits spread outwards, pressing hard against the confines of her tight shirt. Jenny felt a rush of arousal looking at her friend’s fat, still-growing tits, and all the repressed desires she’d felt building over the past few months came to the fore, as Hyejin’s bra burst off, the clasps at the back pulling loose as her enormous breasts grew larger and larger. Jenny hadn’t noticed that her own huge boobs had already popped her bra clasps open. The wildly insufficient cups were hanging limply off her massive mammaries.

By this point, both ladies felt their chests becoming ridiculously heavy, sloshing and groaning with the milk within. Both were pinned to the wall by the bolt of energy from Mudang, and both had expansively large bosoms – Hyejin looked like she was approaching a large J-cup, and Jenny was still expanding at H. Both their shirts were incredibly strained by the massive melons that swelled beneath, and both were staring at each other with barely-concealed lust in their eyes; a deep, animal arousal was pervading their entire, blown-up bodies.

And then, almost in unison, both their tops began to burst open. Their massive, bulbous breasts expanded larger and larger, swollen with milk, and the buttons on their shirts started to pop. First one, then another, then another, it was as if their libidos were being shaken free as their fat tits grew out of their cotton prisons.

Both started to moan as their gigantic tits slumped free of their shirts, and they were suddenly released from their hold on the wall. Instantly they ran to each other, their huge, fat tits shaking as they moved, and held each other close.

“Are you ok?” Jenny asked, stroking Hyejin’s hair and feeling her humongous tits bulge into her own, her rock-hard nipples rubbing against hers, slightly damp from the massive quantities of milk there were starting to dribble through.

Hyejin responded by kissing Jenny hard on the mouth, hefting her enormous K-cup breasts with both hands as they made out hard. Jenny grabbed Hyejin’s ass and started to massage it, before moving up to Hyejin’s own colossal pair of boobs, amazed at how full and bulbous they felt; she knew they were positively stuffed with milk.

And before she could do anything, Hyejin was sucking on her tits, caressing her massive mounds and squeezing them for the liquid within. Jenny’s body was on fire as Hyejin gulped and sucked at one of her massive, distended nipples, and each bolt of milk that fired from her huge breast only gave her more pleasure, and made her more aroused. She was worried she was going to fall to the floor.

Hyejin looked up briefly from Jenny’s huge boobs, to see that Mudang had stopped her yelling, and was staring at Jenny and Hyejin, smiling greedily at the milk that dribbled from Hyejin’s chin. Mudang grinned, and began to move towards Jenny, her long, beautiful legs propelling her across the classroom floor.

Instantly, Hyejin dropped one of Jenny’s colossal tits and skirted around the edge of the classroom. Jenny barely noticed. Neither did Mudang. Jenny only had eyes for the huge-breasts goddess, and as the figure moved closer to Jenny, it became apparent that her breasts were even larger than Mudang’s. Perhaps this was what had gotten her attention.

Mudang stood in front of her, all long hair, stunning face and large breasts, and grabbed Jenny by the head, thrusting her mouth onto one of Mudang’s swollen boobs. Instantly, Jenny started to suck and gobble down the thick milk firing from the engorged teat, and she felt the cold fire of the magic substance hitting her stomach. As she did, she could feel her breasts starting to grow again, and dread began to fill her body. She was going to get even bigger. How big was it even possible to get?

Slowly, her tits began to fill up with milk again, swelling even larger than they had before. They were already too big – if she survived this madness, how was she going to explain these?! Jenny moaned with arousal as her tits inflated, more and more milk swelling them up to inhuman proportions. She was around a J-cup when she’d been attacked, and now god only knew. K? L?

But despite the intense fear she felt at being so huge, there was so much pleasure in the way Mudang’s breasts felt in her mouth, that even the feeling of her massive breasts bulging and expanding into the goddess’ flat stomach couldn’t put her off. The academic part of her brain was remembering every single little detail and storing it for later. If her breasts would even allow her to write anything. She couldn’t imagine she could easily use a laptop with such colossal jugs.

And suddenly, the huge, milk-stuffed breast shot from her mouth, and began to fly across the classroom. Hyejin was standing by the book on the wall, which was fluttering and flapping back and forth, almost as if in pain, as a massive vortex swirled and grew across its surface. It appeared to be drawing Mudang back, back into the pages whence she escaped.

Mudang clung to the desk with her long, slim, powerful fingers, her gorgeous boobs shaking and wobbling, but slowly, she started being pulled backwards. Her face, though completely human (and impossibly beautiful – Jenny would never forget that face), was not controlled by one, and her expressions became terrifying in their inscrutability. A goddess’ rage contorted them into an awful visage, as Mudang shot backwards across the room, back into the pages of the book, which began to shrink and then flopped to the floor.

Jenny sat back, slumped into the chair, her breasts slamming down on the desk, covering a large part of it. Hyejin walked over, her own huge tits shaking and jiggling as she moved, both their shirts completely torn to shit.

“I read the incantation again”, she breathed. “She’s…it’s gone.”

Jenny breathed a sigh of relief, and Hyejin pulled up a chair, sitting heavily next to Jenny, resting her own humongous J-cup boobs next to Jenny’s M’s.

“Wow. You’re pretty big.” Hyejin smiled.

“You’re not so bad yourself.” Jenny rested a hand on one of Hyejin’s colossal tits.

Their breasts were just about touching, but both were too tired – and too turned on – to move them.

“Y’know, about earlier. Um, I just think-”

Jenny leant forward, and kissed Hyejin on the lips, reaching over to caress one of her huge, huge boobs. Hyejin’s tongue returned the favour, hungrily searching around Jenny’s mouth, as her hands began to explore the mountainous peaks of Jenny’s new chest.

Suddenly, the door burst open, and a pair of breasts on legs stumbled in. From the face, it looked like this was…

“Minsuh? Is that you?” Both women pulled apart from their embrace, but it was Hyejin who asked the question. Jenny loved her presence of mind.

The girl breathed deeply, her phenomenal tits hanging down from her chest like watermelons. Her shirt and bra were hanging limply from her stupendous figure, having been torn off the by the monumental growth.

“It’s the girls’ dormitory – something’s happened – you need to come now!”

Jenny and Hyejin looked at each other.

“To be continued?” Jenny asked, pointing her finger back and forth between them.

Hyejin nodded, and wide smile on her face, despite fearing what lay below in the dormitory. She felt like together they could deal with any threat fate could throw at them.

And together, along with their incredibly busty student, the two huge women squeezed out of the door and sprinted down the corridor, their preposterously large breasts swinging madly in the dim afternoon light.
