Yu-jin was angry and her red hairband had been selected specifically to show this.

All the girls on the swim team were in their own little clique, and they never talked to her. They listened to their own music, had their own parties, and she was never invited. She’d hoped this kind of behaviour would stop as she got older, that people would grow out of it, but no such luck.

18 and without a friend at school. It was miserable.

Now she was at this huge swim meet with their rival school, there were lots of toned, 18-year old Korean girls waiting for their chance to perform, and Yu-jin had never felt so alone. She was a good swimmer – almost a great swimmer – and yet she never got the credit she deserved.

She looked at the crumpled up piece of paper in her hands.

They were shaking as she read it. It was a photocopy, from a book that no one spoke about. Rumour had it a certain school up in the north had had…an incident with this book firmly at the epicentre. It was all about goddesses and old magic and no one would say a thing about it, but Yu-jin had been fascinated.

And Yi-jin had seen.

She’d been up to the school, visiting family who lived nearby, and she’d tried to speak to the teachers about it. They were all silent, clamping down when anyone talked about it, and yet they were all…there had been surgeries, clearly, but nearly everyone there was ridiculously well proportioned, to the point of insanity.

No one looked like that in all of Korea, and yet they had a whole school filled with people like that! It made Yu-jin feel very strange, just thinking about it, especially looking down at her own, slim, practically breastless frame.

But she’d been left alone in a teacher’s office – an American who was doing research over there – and Yu-jin had gone digging. She knew the book that those hushed whispers talked about had to be somewhere, and there it was, locked in the desk drawer. Yu-jin had picked the lock with a hairclip, grabbed the book, and photocopied as many pages as she could.

Back home, she’d pored over the copies, of the old, ancient writing and symbols and she’d found the incantation, the one she knew was at the centre of all of this.

Her hands shook even more as she looked at the paper. She hadn’t known when to read it. If she should read it. If she even could – it was old, filled with ancient words.

“Hey Yu-jin – catch!”

A ball smacked Yu-jin in the face, and blood began to drip gently onto the paper.

A group of girls walked past, giggling to themselves. Yu-jin knew who they were. She put up with this every day.

“Hey! You dropped this.”

A girl came over, grabbed the ball by Yu-jin’s feet and hurled it back to the group, forcing the leader to spin around and catch it, almost falling into the pool.

“Are you ok?”

Yu-jin wiped blood away from her nose, folding up the paper quickly before any more spilled on it.

She looked up to see a very slim, very pretty girl smiling back at her.

“I’m Seul-ki, I’m on the other team. Guess we’d better not talk too much!” She laughed.

Yu-jin grinned back, in spite of herself.

“Thank you” She responded, quietly and sadly.

“Don’t let them get to you.” Seul-ki said, sitting down next to her. “If someone attacks, you just attack back.”

“But I’m weak.” Yu-jin said softly, looking down.

“Not if you’re on the swim team.” Seul-ki responded. “That takes strength.”

“Thank you.” Yu-jin said, again. No one had been this nice to her in a long time, and that made her sadder than ever.

“No problem. Try your best out there!” Seul-ki smiled, walking away. “And hey – nice headband!”

Yu-jin looked at the strong, confident girl, and crumbled inside, knowing she would never be like that. She opened up the paper, tears falling from her eyes, dripping onto the red splotches that continued to dribble from her nose, and looked at the incantation.

She’d never be that strong. But Mudang – this goddess she’d read so much about – she might be.

The sky outside was clear, the bright, airy swimming hall full of laughter and faces and noises of life, energy and excitement. And Yu-jin hated all of it. She felt herself fold inwards into a nasty, bitter little ball, and began to read out the incantation.

Almost immediately, the sky grew dark, and clouds began to form. Everyone felt a rumbling begin to shake the building, and laughter and shouts began to turn to cries of fear.

And the paper began to rise into the air, as Yu-jin continued reading the incantation aloud, and everyone looked over at her, suddenly fearful and angry. But Yu-jin didn’t care. They’d had their time. She’d take her chances with chaos.

And a loud, swirling vortex began to emanate from above the paper, a vortex you could only see from a certain angle. But if you were exactly where Yu-jin was, you would see.

Yu-jin tilted her head back unnaturally wide and screamed a sound that shouldn’t have come from a human. Everyone in the auditorium’s blood ran cold, and Yu-jin’s jaw began to unhinge at the top, tilting back further and further, the corners of her mouth tearing and widening as something…came through.

Yu-jin’s eyes were wide and fearful, and she tried to catch hold of Seul-ki’s gaze and say “I’m sorry!”, but her mouth wouldn’t respond. Seul-ki ran towards her, but a sharp, large cloud of dark purple shot through the hole in the world and filled Yu-jin’s wide, gaping maw, raging and burning and tearing until-

The horribly wide jawline slammed shut and Yu-jin sat on the bench, shaking slightly. The vortex was gone. Her eyes were closed.

Seul-ki walked up to Yu-jin, her arm extended a little, shaking herself.

“A-are you…ok? Yu-jin?”

Suddenly Yu-jin’s eyes shot open and they were yellow and terrible, and her body suddenly rose into the air, and her hair began to lift above her, sticking out in all directions.

And she spoke. And everyone in that chamber forgot everything else in the world. For the voice was ageless and sounded like things ending.

“Yu-jin is no longer with us. I am Mudang. You are mine.”

And Yu-jin’s body began to change. Her back arched, and one piece swimsuit stretched over her slender form, as it began to bulge. Her legs thickened and lengthened, her ass ballooned, and her breasts began to swell.

Their progress was slow, but constant. As her ass filled her swimsuit and created big mounds either side of the base, her tits expanded larger and larger, growing more and more full and round with every second that passed.

The whole chamber was staring at this incredible sight, as the formerly quiet, frail Yu-jin grew and grew. She became taller, her legs longer and thicker, but still her breasts expanded. Bigger and bigger they grew, groaning outwards in all directions, bulging towards her belly button as they stuffed her swimsuit more and more full. It looked like it was going to tear open, but instead, bulging cleavage developed as her boobs thrust outwards, each one approaching the size of her head and beyond.

And then Yu-jin – or Mudang – slowly, still floating in the air, ceased arching her back, and lowered her head, and surveyed the scene.

“This one is full of hate.”

It was like a wild animal’s words were being translated into Korean as the goddess wrestled roughly with Yu-jin vocal chords to make the sounds come out. No one in that room forgot what those awful scraping tones sounded like.

And then the terrible hybrid raised its hand in the air, its huge breasts shaking and wobbling, stuffed and full and gigantic, and a blast of pure energy fired out across the hall, knocking everyone to the floor.

As the closest to the horror, Seul-ki was hit first, and was flung back into the pool, where lots of other students had ended up. Thankfully only a few people were rendered unconscious by the blast, and those that were awake grabbed the girls that were beginning to sink, and started dragging them to the side of the pool.

Seul-ki herself was hauling a light, slender 18-year old from her team called Ji-hye when she found the task becoming more difficult. As she kicked her strong, slim legs, holding Ji-hye under her arms, Ji-hye’s back to her, Seul-ki felt an intense pressure wrack her body, and suddenly she began to change.

First of all, her own breasts began to expand. Seul-ki had tiny boobs, but they were tiny no longer. Whatever had hit her was working its terrible magic on her body, and her tits were starting to swell. Feeling panic sweep through her system, Seul-ki kicked her powerful legs and moved Ji-hye closer and closer to the ladder that would get her unconscious form out of the pool.

But as her breasts expanded in her tightening swimsuit, Seul-ki found it harder and harder to propel her through the water. Her swelling tits were pushing Ji-hye away from her, and Seul-ki’s arms were taken up with carrying her, leaving only her legs to do all the work. And Ji-hye was getting heavier.

Seul-ki noticed with shock that Ji-hye’s breasts were also expanding, growing larger and heavier and fatter with every moment that passed. Seul-ki felt her own breasts growing into Ji-hye’s back, as well as Ji-hye’s breasts growing into her arms, as she tried to support the expanding girl.

But Ji-hye’s ass was already undergoing growth, as was pressing more and more firmly into Seul-ki, who was finding the large, wobbling, expanding cheeks more and more problematic as she tried to kick them both to freedom.

There was also the added challenge of the deep arousal that Seul-ki found was flooding through her system – her own growth and the rapid expansion of the girl she was carrying was having a profound effect on her, and Seul-ki found herself more turned on than she’d ever been before in her life, despite the terrifying situation she found herself in.

As her own chest heaved and groaned heavier and heavier, Seul-ki hauled Ji-hye to the ladder at the side of the pool, and heaved her body onto the side, out of the water. Ji-hye’s enormous ass was thrust up in the air, and was still growing larger as she lay there, wobbling and shaking, the huge cheeks swallowing up the back of the one piece between their enormous mass.

Seul-ki clambered up the ladder, her own breasts getting prohibitively large, starting to pack her swimsuit to the max, forcing her to climb the ladder at arm’s length so as to not bump her tits against the rungs.

She hauled her new, heavier body up to the side of the pool, and slumped to a heap, panting and gasping, her huge new ass affording her a terrifyingly high base to sit on. Seul-ki couldn’t believe how large she was already.

Looking down at her tits, which were still engorging and growing a great speed, she felt like her swimsuit may not hold much longer. It felt like two large balloons had been inserted into her breasts, and they were being pumped up with every second that passed.

But it wasn’t with air; her tits felt heavier and more engorged with every inch they grew, and Seul-ki suddenly remembered where she’d heard the name “Mudang” before. Through her panic and arousal-addled mind, she remembered that the name belonged to an old fertility goddess, and that meant…

Seul-ki looked down at her stuffed one piece, and marvelled at the massive melons that bulged out. Her cleavage was now absolutely colossal, her twin peaks smashing together leaving a big, thick line as her two balloons pressed into each other.

And her nipples began to dribble.

They were hard and erect, and tiny white streams of liquid started to seep out. Seul-ki knew what was happening, even as her mind took over and lust started to seep into the core of her very being. She was lactating. This was milk; her tits were so engorged, milk was dribbling out the end. And it was the same for Ji-hye.

Looking over at her friend and teammate, Seul-ki hauled her swollen form, which sported breasts nearly as large as Seul-ki’s – which is to say about the size of large, bulbous melons – until it was sitting upright, her gigantic breasts pouring out of her packed one piece, the fabric being stretched for all its worth by her massive mammaries.

And as Seul-ki moved her into a sitting position, Ji-hye woke up, and immediately started moaning.

“Seul-ki, I’m so full, milk me…pleeeease.”

Seul-ki found herself trying to resist, but something about the bulbous, swollen state of Ji-hye’s engorged, gigantic boobs and the succulent trail of white, viscous liquid that oozed from the end of one of her huge nipples took Seul-ki over.

Almost drooling at the mouth, she grabbed one of Ji-hye’s gigantic breasts, which looked to be roughly an L-cup, and required both hands to fully control it, and shoved it in her mouth.

She manoeuvred herself around so that she was on all fours in front of the dazed swimmer, and hefted the huge tit into her mouth, and started sucking.

“Ooooh god yes, suck me dry!” Ji-hye moaned, as bursts of hot milk started firing into Seul-ki’s mouth. She swallowed the liquid hungrily, feeling like it was the most important thing in the world, gulping and guzzling the hot substance down, feeling it his her slim belly.

And all the while Seul-ki’s butt and breasts were continuing to grow. She wasn’t sure, but she suspected the ingestion of milk was only accelerating the process. Her tits now swung down like gargantuan milky udders, pouring over the top over her swimsuit at the same time as her ginormous ass began squeezing out the back. There was just too much flesh and not enough fabric, and her costume was starting to burst.

“The other one, the other one!” Ji-hye moaned, as Seul-ki removed her mouth from one breast. Seul-ki took a quick break, suddenly dimly aware of how shocking her actions were. What would everyone else make of this?

Turning around to see, Seul-ki was met with an astonishing vision, one that she would never forget.

All across the pool, 18-year old Korean girls, all with stupendously large chests and asses, were having what can only be described as an immense orgy. They massive breasts were being exposed by one another, some sucking on each other’s preposterously large tits to ingest milk, others as foreplay before starting to go down on them or slipping in fingers to begin intercourse.

Up on the bleachers, the coaches and mothers were also undergoing an incredible transformation. Bent by the will of Mudang, they were regressing in age, their faces losing wrinkles and slimming down even as their breasts began to grow in a similar manner to the pupils by the side of the pool.

Before long, everyone appeared to be in their very late teens or early twenties, and were tearing each other’s clothes off to make fearsome love to one another. One mother resembled nothing more than her 18-year old daughter – a girl Seul-ki knew – and her formerly tight, modest white blouse was distended gorgeously by her swelling bosom, before bursting open, the destroyed bra beneath removed by an age-regressing swimming coach who suckled upon one swelling teat with hungry, pink lips, and began gorging on the milk shooting out from within.

Seul-ki watched this incredible spectacle for some time, feeling both weighed down by the enormous scale and heft of her bust, but also both paralysed and aroused by the incredible displays of lust that were taking place all around her.

She saw many of her teammates falling upon one another as their one pieces began to burst open, clawing at each other’s swollen balloons, licking each other’s massive asses and beginning to pleasure one another’s hot, wet cunts as more and more young women succumbed to the powers of Mudang.

And she floated there, emanating power and lust as her massive, pendulous breasts stuffed her bursting swimsuit. The body of Yu-jin was barely even recognisable. Mudang was so huge.

And Seul-ki looked up at the floating goddess, and knew she must do something, anything to make this stop. Every fibre of her being told her to stay, to have Ji-hye suck out some of the enormous quantities of milk that were building up in her titanic tits, which were wobbling and bulging bigger than ever, beginning to curve down to her belly button, but she hauled herself to her feet.

Every step was agony as her breasts swelled larger and more engorged. Her butt was incredible by this stage, both cheeks rubbing against the other, having pulled the one piece completely into her ass crack. She could feel the girth of her butt, and knew it was wider than she was. Only her breasts were comparable.

And as she staggered along the side of the pool, everywhere Seul-ki looked were scenes of lustful destruction. Girls pouncing on one other, sucking their enormous mammaries of milk, before lactating out of their own into other girls’ mouths.

Or age-regressed coaches making out with one another, their tracksuits warped and contorted by the stupendously large, milky breasts that shuddered and shook within. Seul-ki rubbed her eyes and tried to focus. She staggered on.

Eventually, her breasts tearing her swimsuit apart, Seul-ki was under Mudang. She didn’t know what she was going to do now that she’d gotten here, but then out of the corner of her eye she saw the crumpled up piece of paper that Yu-jin had used to start this whole sorry mess.

Seul-ki staggered towards it, her breasts starting to pull her down to the ground with their size and weight, and Seul-ki was soon on hands and knees, her stupendous tits dragging along the ground, her swimsuit ripping apart, a bit thick tear arcing down the middle.

And picking up the paper with shaking hands, just as Yu-jin first had, Seul-ki began to read the incantation, as best she could.

“You. Dare. To. Imprison. ME?!”

Mudang was roaring from above with Yu-jin’s torn vocal cords, in a voice as horrible as rotting flesh, and Seul-ki felt her body rock with an attack, and immediately felt a surge in her breast and ass growth. This couldn’t be. She was too big already. How could she grow any further?

Feeling her tits scraping along the ground, ripping her swimsuit to shreds, Seul-ki stuttered her way through the incantation, tits growing all the while. Soon they were approaching twice the size of her head, and once she finished reading, a howl rent the air, and her breasts started leaking.

She heard terrible voices screaming above her, and knew the vortex had been opened again. Seul-ki was a smart girl, and knew not to look up. She didn’t want to see what Yu-jin had.

So she closed her eyes, and rested her head on her enormous pillows, that were firing milk powerfully out of their engorged nipples, as the world ended above her, roaring and terrible.

And then there was silence.

Seul-ki opened her eyes, and noticed sunlight had returned to the swimming hall. Looking around, everyone appeared to sitting upright, as if awakening from a dream. Some were starting to look mortified at what they’d been doing only moments before, and the coaches and the moms in particular were not making eye contact.

The age regressed people had changed some way back to what they used to be, though they all looked about 10 years young, but their chests, and everyone’s chests were…it was incredible. An entire building full of slender Korean women, with breasts like beach balls. Some swimsuits had survived, but barely. Everyone’s whose hadn’t torn open was hanging by a thread, and the massive, bulbous boobs that were strapped to everyone’s chests wobbled and shook with every breath they took.

But at least they’d stopped growing.

And Seul-ki lay back on the ground, her titanic tits thrusting up in the air, bigger than anyone else’s. She couldn’t believe it; they were just gargantuan.

And as she lay there, she looked at where the vortex opening used to be, and realised Yu-jin was nowhere to be seen. Seul-ki hauled her gigantic form to her feet, almost toppling over at the sheer weight and scale of her bust and ass, but despite searching all over, she couldn’t see her anywhere.

Eventually, moving her titanic tits out of the way, she searched the floor near where the incident had occurred, and found a single, red hairband, lying in a puddle of water and milk.

And that was the last anyone saw of the girl named Yu-jin.
