Lucy could feel every inch of the house pushing back on her body as she swelled fatter and fatter, moaning with pleasure at the feeling of her amazing growth. She was also able to feel her mother and annoying little sister squirming around underneath her flab, the unbelievable softness of her mounds of blubber keeping them safe though thoroughly squished beneath her. The tightness she felt all around her increased as she kept going and the house tried futilely to hold her all in. Window frames broke. Bricks shook loose and fell out. The foundation of the house cracked. The entire house creaked and groaned in protest until it could sustain no more, and the entire structure collapsed and crumbled and folded outwards in defeat as Lucy's many tons of adipose spilled out into the open air.

"Mmmmm, oh, that's so much better," said the immensely fattened girl, her body still reacting aggressively to the formula she had guzzled down. "Now I'm free to grow unrestrained....bigger, Bigger..."

And grow she did. Lucy felt her body swelling faster now that it was free of the confining little house she had just outgrown, ballooning bigger and bigger, softer and rounder, packing on tons per minute as her form swelled and grew out and over the neighboring houses, flattening them much more quickly than it had her own. And the bigger she grew, the bigger she wanted to be. Strangely enough, the formula didn't seem to be anywhere near finished, as her body only seemed to be growing faster as it kept getting bigger and fatter!

"Oh, Yes!!" Lucy howled in delight. "BIGGER! FATTER! DON'T STOP!"
