The library was deathly quiet as Marion swiped her pass and stepped past the gates. She winked at the librarian, whose dour face didn’t return the favour. Marion smiled to herself, shaking her head lightly. It was a beautiful day, and she was looking forward to getting down down to the beach. Her little hot pants felt great in the cool air, and her swimming costume underneath her t-shirt fit perfectly – it was one of those old-school, frilly ones with an open back and padding on the breasts; she was a little flat-chested, and it suited her lithe figure perfectly.

She wandered down the halls, looking up at the towering books, before she came to the section she was looking for. It didn’t actually say “occult”, of course – but that was what everyone knew it as. Lots of old, arcane, scary books – all bollocks, of course, but it was fun to dream. Crowley, Blake, Rasputin, etc. All nutbags, but Marion found it all fascinating. And there was one spell she’d been dying to try.

Scanning the shelves, she eventually found the one she wanted. It was right in the corner, not getting much light at all, and the shelves were pushed narrowly together. She nudged a spiderweb away with a sandal, and looked up. She was pretty short – around 5’3 – but craning her neck – there! She could see it.

Looking around, she spotted a step ladder, and, trembling with excitement, she set it up against the case, and climbed.

Coughing from the dust, she eventually raised her head to the level of the book she was looking for. Its cover was a thick, rich, dark, almost bottomless black. She feverishly opened it and scanned its dusty, creaking pages. They almost seemed to crumble in her hands. Eventually, she found the incantation she was looking for.

Smearing dust on her finger, she traced the image on the pages over the back of her right hand.

“Augmentum corporis mei”, she said out loud, her chest heaving with excitement.

She paused. The air in the library was still. Nothing.

“Augmentum coropris-atchoo!” she sneezed, mid-sentence, sending dust trailing up into the air, which then settled down, all over her, tickling under her shirt, going down the back of her shorts, and all over her legs.

“Shit!”, she cursed, brushing herself down. Tearing out the page she wanted, she made to slide the book back into the shelf, and went to clean herself up. She’d hoped to get taller, not dirtier. Leaning up to return the book, she was suddenly aware of an obstruction, where one hadn’t been before. Looking down, she saw her breasts were pressed against the bookshelf, where before they’d rested just away from it. She pulled the shoulder straps of her swimming costume, which was feeling a little tight, and began to climb down the ladder.

As she looked down, she saw her shirt crease forwards, and beneath, her breasts. Wait – they were…bigger. Weird. She climbed down another step, and felt her costume tighten again. Was her chest…growing? She felt her breasts press into the bookshelf, even though she hadn’t moved. What the hell was going on. Her sandals began to tighten, and her shorts grew a little tighter. Looking ahead, she could see the rows of books moving down. She was moving up. Growing.

“It worked!” she shouted out loud, attracting a loud chorus of “ssssh!” from the the corners of the library. She jumped to the floor with a surprisingly loud bang – she was already bigger. This was incredible. She felt her shorts begin to tighten as her ass inched outwards, bulging into the tightening fabric. She tried to put her growing hands into her back pocket, but found it too tight. On the way back, her arm brushed against the side of her boob, which was swelling outwards, growing with every breath.

The shoulder straps of her swimming costume began to dig slightly into her growing shoulders, as her body stretched. Looking down, she could see her breasts swelling and bulging beneath her t-shirt, growing bigger and more round with every breath, blowing up and outwards in increasingly large, round orbs. They felt incredible.

She heard a rip as her swelling ass began to tear the legs of her tight shorts; little rips began to form at the base, as her growing thighs as they bulged outwards. Another snap, and her sandals popped open. Her feet must have grown two sizes already.

She stepped back in shock, bumping her growing form against a bookcase, causing more dust to fall around her. She sneezed again, her growing tits bouncing with the shock. They swelled about five inches in front of her chest, and she could feel her swimming costume already bursting at the seams. She wished there was some way to loosen it, but she was already too big. Just at that moment, her already large ass swelled another inch outwards, her bulging cheeks tearing further into the shorts she was wearing.

Leaning against the bookcase, she felt her back rise up the books, as she grew taller. Her breasts grew the most though, surging forwards two more inches, bulging against her tight swimming costume. Her t-shirt was pretty stretched, but her costume was bulging beyond all belief, as seven inches of breast poked straight out, creating a mound of cleavage beneath the tight fabric.

She turned to leave the corridor, starting to feel a little claustrophobic as her expanding form started to grow towards both bookshelves. She strode forwards, amazed at both how tall she was getting (she was at least 5’7 now), and how large her breasts were becoming. She could see them squeeze further and further into her tight swimsuit, bulging up and out as her growing flesh tried to be contained by the struggling material. She was incredibly glad there was no back to the costume, as that gave slightly more room at the front to contain her swelling melons. They were about nine inches, straight out now, and her nipples were huge, and incredibly sensitive. Each step caused rubbing, which turned her on a huge amount.

She reached the end of the corridor, glad to have escaped; just as she was leaving, her huge tits were beginning to touch either side of the corridor, so swollen were they. Turning for the door of the library, she realised how tall she’d gotten. She could see far further than before; her legs were much longer, and her ass and tits were growing the whole time. She could feel her shorts really struggling to contain her growing cheeks, and her costume was tight all across her, desperately trying to hold in her massive jugs.

“Snap!” One of the ties across the back of her neck holding her costume on gave way, allowing her huge tits to surge forwards, filling up more of her t-shirt, which had ridden up in an attempt to contain her colossal size. She bulged outwards, continually growing, as she wobbled forwards towards the door. She could see the sides of the book case move lower as she grew, and she could feel her huge tits wobbling from side to side with each step, bulging further and further out from her thin frame.

Marion tried to reach behind her neck to re-tie the strap of her swimming costume, but in doing so, she thrust her breasts forwards. That was all her shirt needed, as the side stitching started to give way. It was like two beachballs were contained in a now very small t-shirt, and it wasn’t going to hold much longer. Marion struggled with huge, fumbling, still growing fingers at the back of her long neck, trying to tie the straps of her swimming costume back together. Reaching around unwittingly made her massive boobs look even bigger as she thrust her humongous tits forward, arching her back.

There was almost no strap left, as her huge chest was pulling forwards with increasing severity with every passing moment, but eventually Marion got a tight knot tied at the nape of her neck, just about containing her incredibly swollen, and increasingly sensitive tits. She could feel them swinging with every step, growing bigger and bigger, with no sign of stopping. They must have bulged out around eleven inches now, directly in front of her. She couldn’t believe it. She was starting to get really, really horny. At that moment, her shorts tore open a little more, her growing ass bulging out of its increasingly inefficient container. Her cheeks were so big and round now – she couldn’t wait to get a big hard cock near them. The thought made her really wet.

Wobbling further towards the exit, still growing taller, Marion realised she was almost six foot now. Her shirt was a parody of tightness, barely covering the underside of her huge boobs, looking like she’d left a wet cloth resting over two huge melons. As her massive tits swelled bigger and bigger, she realised she’d need to get somewhere private soon. Her swimming costume was holding for now, but it was riding really high into her cunt, something which was turning her on more than words could say. Every step rubbed against her clit, and drove her increasingly wild. If she didn’t watch it, she found her hands started to drift down between her legs. She noted with delight than once they were around her belly button, she couldn’t see them at all – there were two twelve inch zeppelins bulging forth in front of her.

She couldn’t take much more of this. Still growing, bulging and wobbling, she padded to the exit, smiling again at the librarian. She lowered her glasses with amazement, unable to connect this swollen, humongous, toweringly busty Amazonian with the meek, petite girl who’d walked in ten minutes before. Marion blew a kiss, and giggled, before a further growth spurt ripped her shorts in two, revealing a very, very big ass with a very tight swimming costume riding up between two enormously round, firm cheeks.

“Serves me right”, thought Marion, as her breasts pumped forwards, bulging tighter and tighter against her swimming costume and t-shirt. She was truly massive now, and still growing.

Reaching the gates, Marion felt in her pockets for her pass. Feeling her massive thighs and ass, she realised with a laugh then sent her whole huge body jiggling, that her pass was in her destroyed shorts. Still noticeably growing, she simply lifted a massive leg and strode her 6’5 frame over the low barriers, growing bigger and bustier the whole time.

Stepping out into the sunshine, she stretched, and realised how huge she’d become. Her breasts were like two enormous medicine balls on her chest, bulging out about fourteen inches in front of her, and her very, very tight swimming costume was fit to burst, even with the amendments she’d made. Luckily the beach was very close. She made for the slope down to the sand, trying not to run; her titanic chest was wobbling enough with just walking – running would be the end of it.

Her feet were so huge, her tits so gargantuan, her ass so round and full. As she walked through the sunlight, she felt herself grow and grow and grow. To anyone watching, her tits which seemed so ludicrous to Marion, were only plain massive on her giant frame. Still the biggest breasts most people would ever see, but as she approached seven feet, and her enormous, swollen ass grew bigger, it all seemed just in proportion. But only just.

People stopped and turned as this gigantic, swollen beauty bounced onto the beach. Marion’s swimming costume was so tight around her bulging body, that it would give any moment. Her t-shirt was barely able to cover half of her impossibly large bust, which surged about sixteen inches straight out in front of her enormous form. Her huge nipples poked through the remnants of her swimming costume, but everything was giving way as her massive form swelled bigger and bigger.

Each footprint in the sand was bigger than the last, as her colossal form strode across the beach, heading for the water. She decided to get out of sight before her tremendous tits burst free. She only had seconds. They were bulging and wobbling forth with every passing second. She vaguely wondered when they’d stop, but realised she didn’t care; she was too horny to think about anything but pleasuring herself. She suddenly realised the spare page was back in her torn shorts, which littered the floor of the library. She’d go back for it soon. It wouldn’t take long if she kept growing. She could practically reach the door from here, she laughed to herself, her massive tits swelling.

She stepped into the water, feeling the cold on her huge toes. She strode more quickly into the water, finally hoping to be out of sight so she could expose her massive mammaries. It took her a long time to get under water – every time she thought she’d be fully submerged, she grew a little more, swelled and bulged a little bigger, put a bit more strain on her costume, which looked more and more like a toy’s outfit on her giant figure.

Finally, she dipped her tremendous melons underwater, and breathed a sigh of relief as she burst out of all of her clothes, her enormous, 7’2 form finally allowed to bulge free. Her tits swelled to about seventeen inches in front of her, and she had crouch down to stay underwater. She couldn’t crouch too far though, as her swelling tits were still growing, and provided her with no room. Eventually she got far enough into the depths to completely relax.

She was so huge. She tentatively felt a massively swollen nipple, and practically came there and then, so sensitive was it. She reached one huge hand into her now massive cunt, and began to pleasure herself, the other tweaking a still growing nippled on a still bulging chest.

Sparks flew in front of her eyes, and she thought was going to explode – still bulging, growing and swelling, she came spectacularly and loudly, causing everyone on the beach (who were, admittedly, already looking at the incredible spectacle), to stare even more.

She stood there in the water, still growing until her shoulders had broken the surface, her breasts and ass still getting bigger, and wondered just what on earth she was going to do. She raised one hand out of the water, and noticed a long string of seaweed on it.

She paused, for a moment.

A smile broke out across her face.

Arranging it into the symbol from the book, she parted her huge lips. Her voice was shockingly, excitingly deep. She was so big already. But it wasn’t enough.

“Augmentum corporis mei.”

She stood, water lapping over her tremendous shoulders.

And Marion waited.
