"Got you!" Kate said, taking the small idol from the decrepit alter. Surprisingly, considering how old and decayed the alter and room were, the idol was in great condition, almost like it was brand new, except for the layers of dust from its long stay there. Kate was excavating an old ruin she had found in the jungle, isolated from the rest of the world. Most of it was underground and partially hidden, but she was still surprised that nobody else had discovered it, considering that she stumbled across it accidentally.

Kate herself wasn't anything particularly special, just a girl in her early twenties joining some researchers studying some of the cultures in the isolated jungle, and she was just on her way to the other side when she found the ruins. Physically she was fairly fit, slim, and not particularly strong, giving her a someone thin look on her limbs. She had short brown hair, only reaching halfway down her neck, most of it under a green cap, shading her fairly pretty features, with green eyes and a light sprinkling of freckles, but otherwise unnotable. Since  she had found the temple, she had been extremely excited by the idea of exploring an unknown ruin, and had quickly set up camp and grabbed  just inside, away from the heat and insects, grabbing her torch and a small bag to store whatever she could find.  When she had gone exploring, she hadn't gotten much in the way of excitement, mainly empty halls, shattered pottery, and faded and indistinct art. This was still enough to excite the amateur archaeologist, and she had stored what she had found by her tent.

But when she had found the shrine dedicated to the idol, her hear had skipped a beat, and she immediately went to take it, leading to the above. She turned the idol over, having a look at it. It was a small fertility idol, about the size of her head, of a short pregnant goddess, with wide hips and large breasts, essentially the typical depiction of a fertility goddess for any tribe. It was made of what appeared to be clay, and once again, she noted, something that certainly should have taken some damage from the ravages of time. Still, she wasn't one to complain about a well preserved relic, and she put took it back to her camp, depositing the other things she had found next to her tent. Strangely, she found herself putting it back in her now empty bag, strangely drawn to it for some reason. She reasoned that it was because it was her biggest find, but she still couldn't really explain why she did it. She put it out of her mind and headed back to explore the ruins, heading to one of the lower levels.

Sadly, the idol was her biggest find of the day, and while there were still levels of catacombs to be explored, when she went back to her camp, she found the set was in the final stages of setting, and decided to set up camp. She kicked off her boots and took of her cap, relieved to get it off. It had been getting tighter for some reason, and she had to loosen it several times, each time getting just as tight as before. Her clothes seemed a bit tighter as well, although that could have been just it clinging to her from her sweating. She entered her tent, putting down the idol as she lay out her sleeping bag and stripped down to her underwear. She took a mirror out of her bag, about the size of her hand, and had a look at her head, noticing that her head was a bit thicker than it was the last time she had looked at it. She hadn't had a haircut in a while, so she decided not to worry about it, and get into her sleeping bag, since the ruins were cooling down quickly. Getting into her sleeping bag required a bit of effort, since it was fairly thin, and while it didn't usually take too long to get in, her hips  just couldn't fit in on her first try this time, and it was a minute of struggling to get inside. Even after she got in, her hips caused a problem in the normally adequate once in sleeping bag, but she ignored it and went to sleep fairly quickly, unaware of what was happening to her, the idol next to her beginning to take charge.

Kate woke slowly, feeling numb and compressed for some reason.  She tried to turn over to relieve the feeling, but it didn't help at all. She tried to pull herself up, but only heard a tearing sound as her sleeping bag ripped right open, unable to contain what was within. Kate pulled herself up and got out of her tent, feeling very off balance and strange. Light leaked through the entrance to the ruins, and Kate looked down, gasping at what she saw.

Her belly was huge, appearing to be holding at least triplets in size, and her skin had darkened to a very dark tan, her skin a light brown colour. Her belly was perfectly smooth, with no stretch marks or imperfections, and Kate felt very heavy, but not uncomfortable with it, and found herself able to walk perfectly well with it, which brought her attention to the rest of her. Her breasts had swollen to an immense size, completely bare as they broke out of her bra earlier that night, now resting on her belly, feeling full of liquid and sloshing when she moved. Her hips were extremely wide, her underwear having broken due to her huge thighs that complemented the rest of her pear shape, enormous rear jiggling as she moved. Her hair had grown too, reaching her waist, extremely thick and lost, carpeting down to brush her hips.  She bent down awkwardly to retrieve her mirror, and had a look at her face, which had changed too.  Her face was much rounder, very full and friendly, with what was almost a second chin, but not enough to call her overweight. The overall beauty of her face had increased as well, now with a youthful and ageless quality that increased it from merely pretty to beautiful. The rest of her body had thickened out as well, her thin arms going to full and thick, not quite enough to call her plump, but a very full figure.

Kate, oddly, didn't panic at these changes. She knew that she should, but she felt very comfortable with the changes, like she was always meant to be like this, and this was how she should be. She had no desire to change herself back, and was happy  to carry her enormously pregnant and naked body around, as she climbed into her tent, retrieving the idol from inside. She realised that her body matched the proportions of the idol, and a feeling of serene calm and warmth washed over her as she realised who she was and who she wanted to be. She was a fertility goddess, given this form by a relic of the old tribe, and this place was her home. She considered leaving, but then wondered why she would ever want to. She abandoned her tent and findings, heading deeper into the ruins, to settle herself into her new home.
