Sydney slowly rubbed her ass slowly, feeling the mass and mapping out how it felt in her hands. She purred a little as she did. It felt... good. It felt really good to be this bigger.
So why not have some more?
Sydney reached for another peach, greedily chowing down on it before spitting the seed into a trashcan. She almost sat back to enjoy the coming growth but then had a devious idea.
If one peach made her this big... what would multiple be like?
Sydney smiled widely as she chomped down on yet another peach... and another... and one more for good measure. Finally, she tossed the seeds and awaited her growth.
A few moments passed, and just as she considered having another peach, she felt something in her butt. This was different though. A low, deep gurgling and rumbling seemed to emanate from somewhere deep within her booty. Sydney lightly patted her rear before suddenly recoiling her hand as she felt a *thunk* in her buns. Then, it began to grow. Whereas last time the growth was slow, methodical, gentle, this time was not. Sydney squeaked as her ass suddenly swelled up a good half a foot in a second, groaning as the new weight pulled heavy on her back and weighed heavier on her thickening legs. She turned to watch as her ass seemed to wobble and jiggle like Jell-O in an earthquake, despite her standing still as a statue. Grunting as she felt her ass push out again, she groaned in pleasure. Why did it feel so good to be huge? She could barely think straight...
She gazed at herself in a mirror, her concerned thoughts melting away as she admired her approachingly beach-ball sized derrieré. She watched with a foggy smile as her cheeks seemed to pulsate, the individual butt cheeks seeming to move independently of one another as they swelled. They even grew out of time: one would become more engorged than the other, leaving her butt size rather lopsided for a moment before the other would catch up.
Sydney growled as she felt a deep, deep feeling of desire awaken within her. She wanted her ass to be humongous. Beyond huge. Beyond oversized. She wanted her big, fat, creamy, monster ass to never stop growing. She almost reached for another peach before some small part of her senses warned her to see these through before acting on more. She hesitantly retracted her hands, instead choosing to proccupy them with playing with her still fattening caboose.
The sounds coming from within her bottom had become increasingly loud and gurgle-y as she grew. The sound of her trunk being filled with whatever junk was in it filled the room and overpowered Sydney's normal speaking voice. She whimpered in delight as a loud *blort* resulted in her cheeks clapping and widening further.
By now Sydney's ass was the size of a golf cart. Her legs and thighs were equally enormous, giving her the appearance of a girl stuck from the waist down in a blob of fat wrapped in skin. It felt amazing, she thought, as she pressed her ass against the ground and moved it about, the sensations of her ass simply touching things causing Sydney immense arousal, feeling the fat inside slosh and compress as the skin of her ass creaked and groaned as it tried to contain the monster amounts of blubber within.
After 10 more minutes, Sydney felt the last pulses of growth course through her ass and sighed. She admired her ass (what little she could see) both in the mirror and by craning her neck as hard as she could. Content, Sydney laid back on her now car-sized booty, occasionally groaning in pleasure as every little movement caused her cheeks to shake and ripple like water in a pond.
