Not Fat, Partially Inflated

"What do you think of Kelly Small?" Dave asked Andrew as they sat in the cafeteria.

"Don't you mean Kelly BIG?" Andrew asked back, using the plump girl's nickname. "I don't think about her at all. She's kinda chubby, don'tcha think?"

Dave stared out into space. "She is plump," he said. "But I don't think it's fat."

Andrew gave him a funny look. "What are talking about?"

"I don't think it's fat," he repeated. "If you look at her closely, there's no folds of fat on her, just smooth skin. And when she walks, she doesn't seem to be slowed down by her weight. It's almost like she's big, but not fat."

"What are you getting at?"

Dave finally looked at him. "I think she's just partially inflated."

Andrew started laughing--until he saw Dave was serious. "Are you telling me you think she's that big because she's filled with air?!"

"That's exactly what I'm saying," Dave pressed on. "I have a theory: I think she's a walking, talking inflatable doll; and that if you just poked her, she'd blimp up even more."

"Dude, you're sick."

"True," Dave admitted. "But I can't stop thinking about it. I keep imagining her blowing up like a balloon, just getting bigger and bigger. It's so beautiful. She may look chubby now, as a heavyset person; but as a balloon, I bet she'd be gorgeous."

Andrew shook his head in disbelief. "If that's your theory, why don't you test it? Why don't you give her a poke?"

Dave shrugged. "I'm a coward."

With a bemused chuckle, Andrew made his way to fifth period.

But the seed had been planted.

Kelly Small was in Andrew's biology class, and he found himself staring at her. He decided that, yes, if she lost a few pounds, the young blonde might be mildly attractive. But she was just so big... He kept staring at her. As the class progressed, he noticed that, yes, there was a sort of "lightness" about her, as if her movement wasn't hindered by excess pounds. Her skin was smooth, with no visible signs of fat. Just a kind of pleasant roundness to her features.

Andrew would continue to stare at her every day for the next week.

And then he would think about her when he was at home. Constantly. He found that he would get physically aroused by thinking about her... but how was that possible? He was never interested in fat chicks before.

Unless... she wasn't fat. She was just partially inflated.

He shook the thought from his head--but it didn't leave for long. He thought of her just as she was... and then he thought of how she would look if she were bigger. And bigger still. Then he thought of how she would look if he could actually SEE her get bigger.

And finally, he imagined her as a balloon. He thought of little else for the next few days, until it drove him insane.

He caught Kelly at her locker after school, long after the hallways were emptied. Kelly had no friends to speak of, so it was little surprise to see her alone.

Andrew approached her. "I think Dave was right about you."

She gave him an annoyed look. "What are you talking about? And why do you keep staring at me in class?"

"Dave has this theory," Andrew continued. "He thinks you're not fat, just partially inflated."

"Oh, that is so funny," she sneered bitterly and turned to leave.

But Andrew blocked her path, and she stopped suddenly, as if afraid to touch him. "He also thinks," Andrew went on, "that if I poked you, you'd just bloat up like a blimp."

"Get away from me," she told him, and she tried to step away.

But then Andrew poked her.

"Don't!" Kelly cried, but it was too late. There was a soft hissing sound, and her entire body filled up noticeably bigger: her stomach; arms and legs; her hips and thighs; her breasts and her ass--all swelled up like a tire on a pump.

"Oh my god," murmured Andrew. "It's true."

"Please don't do that!" Kelly urged him. "I have to avoid bumping into people, or I just bloat up like this. And I don't want to get any bigger!"

Andrew's eyes lit up. "How... how big can you get...?"

Kelly looked terrified. She backed away from him, about to bolt away.

But Andrew poked her again. "No!" she yelled, but her body began to hiss and bloat up all over. Her jeans, already tightly packaged, groaned as they filled out farther, stitches snapping as it lost the battle to contain her expanding butt. Her sweater fared little better, as her swelling stomach and breasts stretched it out across her ballooning figure. Andrew heard the strap on her bra break apart, and her breasts made a sudden lunge forward. Then the hissing slowed down, and Kelly's expansion gradually slowed and stopped. She stood there, her clothes torn but still holding, a bloated version of herself.

"So beautiful," Andrew whispered in awe. Her body, though swollen, did not have the characteristics of an overweight person: no cellulite, no stretch marks, no creases of fat. He felt her spherical stomach to admire the smoothness of her body. She clearly wasn't a fat woman. She was just a balloon.

And all he had to do to make her bigger was...

"Please! Stop!" Kelly shouted as he approached her again.

"No," he said simply, and he poked her belly once more.

The hissing began again. Kelly let out a wail as he her body blimped out farther and farther, her sweater and pants giving up and the fight and bursting apart. All that remained on her was her panties, riding deeply up her inflating behind. But it was not as if there was much more to see: Her girlish features were gone, replaced with just a round, ball-like body that kept growing bigger. Bigger. Bigger. Her arms and legs were virtually gone, with just plump hands and feet sticking out her globular figure. The hissing gradually slowed again and stopped, leaving Andrew to admire his handiwork.

"Please!" Kelly repeated. "Look at me! I'm so big and full I don't even look human anymore! Please don't make me any bigger!"

"But you're so beautiful," Andrew assured her. "I've never seen anything so beautiful in all my life! You're the biggest, fullest, most beautiful balloon ever! I--I've just got to make you bigger!"

"Help!" Kelly cried out, but none was forthcoming. He poked her again.

"Noooo! I don't want to get bigger!" But her cries had to be shouted over the hissing sound that accompanied her increased expansion. Her body grew bigger, so much bigger, as she helplessly inflated. Andrew stood entranced as she filled up the hallway, her body now so puffed up that no one could get around her. Her head got closer and closer to the ceiling as the inflation pushed it higher and higher into the air. Her skin pulled tighter and tighter as it grew more and more transparent. She grew and grew and grew until once again she slowed to a stop.

"I'm begging you!" she called out to him. "I'm so blown up, I feel like I'm about to pop! I don't want to explode! Please! If I get any bigger, I just know I'm gonna BURST!"

Andrew ran his hand over her tight, round body, admiring its smoothness, relishing the squeaks her body gave as it fought to keep the air inside her. "You know," Andrew said. "I think you're right. I don't think you can get any bigger. One more poke, and you'd inflate till you popped!" He outstretched his arms and, as best he could, wrapped them around the front of her body to give her a hug. Then he stepped back to give her another loving look. "Goodbye, beautiful, beautiful balloon-girl!"

And before Kelly could protest... he poked her once again.
