After a moment of being immobile by the sheer size and weight of his stomach, the familiar rumbling could be felt in Peter's stomach.
As he strained to move, he felt his back and leg muscles bulge and grow. Belatedly, he realized by straining to move, he was using those muscles more than anything else, and they would grow first as his metabolism began to convert the huge reserve of food to muscle.
Giving one more heave, Peter found he could once again stand- but what a sight it was! His jeans splitting under the dual strain of his stomach and his still growing calves, and his shirt tearing as it bunched up under his massive pectorals and on top of the huge sphere, it was only a matter of time before they became so much scrap.
