Mary now had a large rat's tail, but she didn't want to stop there. She looked over the multitude of choices until she found a vial with a picture of a pig.
"Now that's cute," she thought. "A little bit of this wouldn't hurt." She took a few sips from the vial and then put it back. She waited anxiously for any changes. This time she was positive they were coming.
She tried to pass the time admiring her new tail. Others may not have chosen her particular kind of tail, but Mary had always had a fascination with animals that weren't exactly high in popularity. She'd wanted a pet mouse when she was younger, but her parents forced her to settle with a gerbil.
Mary was enjoying the feeling of sliding it around the carpet as she walked when she felt something in the pit of her stomach. All of a sudden she developed a ferocious appetite, even though she had just eaten breakfast. She hurried to the kitchen as her stomach growled loudly. She grabbed as many bowls as she could and filled each one with cereal until the box was empty. then she drowned them in milk and began scarfing them down. She dispensed with the spoon after finishing the first bowl, settling on the quicker method: dumping the contents directly into her mouth.
Once every last drop of cereal and milk was devoured, she sat back in her chair. Her stomach was content at last, and she patted it gently as it audibly digested its bounty. It was larger now, poking up through her shirt. Mary knew she'd have a lot of trouble tucking her shirt into her pants now, but seeing as she couldn't wear pants thanks to her tail, she didn't consider it a major problem.
She continued to lounge in her chair for a few minutes, running a finger around her bulging belly. It felt so good to be full. Really full. She almost drifted off to sleep, but was startled as something else began to happen inside of her.
It felt as if her stomach was redistributing its food. She felt her plump belly shrink under her hand as a warm weight coursed through her. Slowly, her entire frame expanded. Her waist tightened around her panties, her arms pressed against the inside of her sleeves, and her hips widened. It was a minute change, but she could definitely feel it. She looked down at her stomach, and its unusual bulge was all but gone. It stuck out a small bit, but compared with the minor increase to the rest of her body, it looked perfectly normal.
And then she heard it grumble again. It was empty, and even more starving than before.
Her brain had no room to think about why it was happening, all she cared about was filling that massive void. She tore through her refrigerator and devoured packages of salad, deli meats and any leftovers she could find.
Minutes later, she was again rubbing her protruding belly and sitting back against the side of the fridge. It was so large this time, her shirt had ridden up, completely exposing it. All around her were discarded wrappers and Tupperware containers. She couldn't believe she had eaten so much. Her sudden appetite was making her such a pig.
Then she laughed. Of course! She chuckled and chortled so hard that her round stomach shook and jiggled. Her laughter suddenly erupted into a series of snorts and oinks. She hushed up, putting a hand to her mouth, but soon found herself snickering again. She sure was a pig, all right.
Her stomach started its rapid digestion once again. This time, Mary prepared herself for the growth, but what came next turned out to be a surprise. Her arms weren't changing, neither were her legs or her waist. It seemed concentrated only in her chest. Her bra tightened painfully, and Mary struggled to remove it. She let out a loud sigh as it came off, and she felt her growing breasts flop against her chest.
But her changes weren't finished yet. An indescribable sensation emanated from her chest, and she could feel even more weight forming on it. She lifted up her shirt and discovered that she had six brand new nipples lined up between her breasts and her stomach. They were moving outward as six mounds formed around them. In no time at all, Mary had three new pairs of breasts. They were so large and packed together, she could feel them pressing and rubbing against each other. She squeezed them and moaned in pleasure. As she came out of the haze of her new transformation, she realized that her stomach hadn't completely retreated into her. She still had a very noticeable tummy. It was round and cute, and her bottom pair of breasts were resting on it comfortably.
She got to her feet very carefully. Her two rounds of expansion had caused a tremendous increase in weight, but somehow it seemed that her body hadn't just gained fat, but muscle as well, so that moving around wouldn't be that big a problem. Even so, she wasn't used to hauling so much, especially now that she was so front-heavy. She leaned against the fridge, adjusting to her new body.
When she felt ready, she began to trudge across the kitchen. She giggled and oinked at the strange sensation of her breasts swaying and bounding, knocking into each other, and her belly wobbling to and fro. She was glad that her large rat tail was helping keep her balance, otherwise she feared she'd have been forced to all fours.
She lugged her pudgy form into the bathroom and removed her shirt to examine herself more closely. In the mirror she confirmed that her original breasts had grown over a full cup size. Her other breasts were slightly smaller, but still decently formed. Her arms, legs and hips had an extra amount of girth, but she still had a hint of her womanly figure and didn't look obese by any means. Her cheeks also looked a tad rounder. The only real giveaway was her massive tummy, but it seemed she'd still be able to get pants around her waist...that is, if she cut a hole for her tail. Also, she couldn't be sure, but she thought that her ears were a tiny bit pointed.
Giggling gleefully, she waddled back into the living room and stood over the vial box once again.
