Joce quickly wished that Peter was somewhere he couldn't be seen.
Peter groaned as he looked up at the giant stomach in front of him. He was lying on his back somewhere in the wilderness, no longer pressed against the walls of the gym, but he was still huge! He put his hands against his stomach, marveling at how firm the sphere was, even thirty feet in diameter. It was like his stomach was a hot air balloon. He'd never felt so full, or so big, in his life, and he liked it.
Suddenly, the skin of his stomach began to shiver and ripple, like it was a giant glob of jello. It was shrinking! Peter stared as slowly he could reach halfway around the sides, then finally peek over the top to see the scenery around him.
It was then he realized his stomach wasn't shrinking, but he was growing! No longer was he a muscled boy attached to a giant ball of a stomach, but a huge, massive man with a taut protruding gut. His growth slowed when his stomach rested comfortably as half a sphere, starting from two massive pectorals and ending just above the most impressive package. He could just reach around the total of it, his small mountain ranged sized biceps pressing against it.
He grinned, then cupped his hands and concentrated. Joce appeared, still normal sized save for her massive breasts cradled in his palms. they filled his now giant hands just right.
Peter grinned, the possibilities endless!
