Huff and Puff

"I can be bigger than that!" shouted Huff. She grinned and inhaled, resting her hands on her sides
as she looked down to watch her waist slowly expand. A hissing noise began to rise from within her
as her torso expanded outward with all the sounds of a child's balloon. Her waist quickly widened
as the surge of growth shot from her tummy into her thighs and butt, working its way into her
extremities. Her blue rubber suit expanded with her as she began to slowly round.

Puff had different plans. She inhaled as deeply as she could. "I can beat that!" she howled, as a gust
suddenly filled her and she ballooned outwards in all directions. Her red rubber suit groaned and
complained as her body suddenly tested the limits of its seams. Within moments she was already
totally round, with only her hands, head and feet visible. She wiggled her hands and feet frantically
as her inflation suddenly died down to a crawl.

Huff grinned as her inflation continued. Her entire body swelled but maintained a human shape,
unlike her sister, who now resembled a giant tomato. Her arms and legs widened and widened. She
appeared as though she were some gigantic, latex clad, circus fat lady, gaining spontaneously. Even
her hands and feet puffed up a bit as she continued her growth. She slowly ran her hands over her
widening sides, pressing in hard to make herself squeak like a balloon. Her rubbery body gave to her
pressure and her hands sank deep into her sides, forcing air into other parts of her body and suddenly
expanding them. An evil glare came into her eye as she glanced over at Puff, who had barely grown
any more. "We're just gettin' started kiddo.."
