The pressure in her stomach continued to build as it filled with gas. Soon it wasn't just a matter of feeling bloated, she could actually feel her stomach begin to stretch. Moments ago she had said the feeling was like having eaten a huge meal, but that wasn't accurate anymore. Her stomach felt painfully stretched and at the same time, light and airy.
Bent over in agony, she found that she could no longer hold that position due to the way her stomach was filling up. Straightening up she saw that her stomach was pressing against her shirt and starting to push against her skirt, forcing it down a few inches. In one last effort to stop the swelling she pressed her hands against her stomach. It felt tight, firm and entirely unyielding. The sensation was similar to pressing against an over inflated balloon save that it was warm and fleshy rather that cool and rubbery. There was another similarity to a balloon though, she could see it inflating right before her eyes.
Still filling with gas, her stomach had begun to push her shirt up, revealing its increasingly round form. Despite the immense growth, there was no feeling of weight, just an awareness of a large quantity of air in her that was masked by the pain of the inflation.
Katie wrapped her arms around herself, only to feel her stomach begin to push her apart. For a moment she reached a point where it looked like she was pregnant, but the swelling quickly went beyond that. The only mercy in the situation was that the growth was confined to her stomach, otherwise the pain might have been too much for her.
After reaching the point where it looked like she had a large beach ball inflated in her stomach the pressure began to fade and the growing slowed and then stopped.
Though the pressure was gone, she could still feel the gas in her stomach, gently pushing against the sides. She tried to force herself to burp, to see if that would make it go away, but nothing happened. Shocked she rubbed her hands over her immensely swollen stomach, so large that she was unable to wrap her arms completely around it. She shifted on her feet and was even more startled to discover that she hadn't gained any weight, she was just full of air like a balloon.
Horrified, she turned to Tiff.
