Zhu Yuan went on a patrol mission into Hollow. After some time she found a strange big Ether Crystal that was never seen before. She knows they tend to corrupt people but she came closer to inspect it out of curiosity. She slipped on some rubbish and fell on it with her boobs, she quickly backed off but after some delay it caused them to grew big enough to snap her shirt while revealing her black bra with pointy nipples seen trough. She is shocked at first but it was so much pleasurable that she decided to rub it with her belly. Again after she finished rubbing it, she turned around and after some delay her belly slowly grew bigger than her breasts. While it grew it stretched the belt and much later snapped it. Addicted to how it felt she went with her ass next and rubbed crystal with lot of up and down movements. (Her pants were latex-like so her butt made extra squeaky sounds and they were more durable.) It started to grow slowly at the beginning, then after some time it went faster and later her thighs joined in too. (Crystal is semi x-rayed to see butt clearly.) When her panties became visible through pants they just slowly stretched more and more like a string. (Because of durability pants became more semi-transparent as they stretched.) Totally lost in pleasure and without thinking straight anymore she just absorbed trough rubs more and more of the crystal power. After her ass grew big enough, she slapped her huge ass so her pants went into shreds but panties remained intact. Zhu's ass and belly grew (belly grew at much slower rate than ass) with each move and after some time, she cummed and her growth ended by absorbing the crystal completely, with her being at least mansion sized, with butt being enormous compared to rest, belly being huge and boobs much smaller than belly but still big. (Her arms and legs swelled a little too but every body part is clearly definied.)
Briefly: breasts -> +belly -> +butt (expansion)
