Peter quickly drained Joce's laden breasts of their overstuffed juices, returning both massive mammaries to their magically semi-pert stage. Finishing the last one, he grinned before letting out a burp that shook the both of them. Joce laughed. "Excuse you!"
"Heh. Sorry." He said, and patted his stomach. He'd already looked overstuffed with muscle, now after his big drink his abs were pushed out even further, looking like he'd swallowed a watermelon whole. Under his hands he could even feel the liquid slosh a bit. It was a satsifing feeling, but quickly faded, as his gargantuan body quickly digested, and his stomach flatten (or regained it's original shape, at least) in a matter of moments.
Joce, even from her disadvantaged view, was amazed. He'd must have drank at least 4 gallons. "Wow, quick metabolism..."
Peter seemed to contemplate this for a moment. "Yeah...Hey, could make me about half my size- just the muscles, at least?"
"Ok..." Joce tried not to sound too dissappointed. He felt he was too big already? Normally he was the one who kept egging their games on, when only she'd been in control.
But Peter, now more the size of the largest football player in school grinned and focused his attention back on his idea. Joce looked at him, confused at his grin until that familiar tingle returned to her chest, almost masking the feeling of Peter's hands supporting her.
Before, Peter, more interested in the process than the size of her cleavage, had grown her out inch by inch. Now, as he kneaded their soft fullness, they expanded in feet, quickly filling the space between them, then pushing him back.
Joce was almost completely distracted by the orgasmic feeling of growth coupled with the feelings of Peter's hands. She watched from half lidded eyes as Peter's growth was triggered by his growing her. As she barely registered her breasts brushing the middle of her thighs, Peter's body swelled in all directions, muscles fighting for space. He grew taller only by inches, but his pectorals, shoulders and arms seemed to push out by feet. The combination growth pressed her back into the lockers.
Finally, when it finished, Joce's breasts had pushed her off her feet by three feet. No longer measurable on any cup scale, they were each the size of a small compact car! Even at this oversize, they didn't sag. Pressing into them she could feel that were soft but full.
But even in the large locker room, whatever space she didn't fill, Peter's body took up. He redefined the idea of musclebound- he was a mack truck of muscle!
Peter's pectorals, roughly the size of a refrigerator loomed over her, almost blocked her view of his face. He was fifteen feet tall, his head just brushing the cieling, and just as wide across. Between his wrecking ball shoulders, luggage sized biceps and what she could see of his redwood legs, she couldn't imagine how he could move. Her breasts pressed against him, and between her massive chest she could feel his member, which had to be a full oak tree.
Peter grinned and shifted to touched her breasts with his giant hands. Suddenly, she gasped as her breasts plumped further, as if filled with air.
He leaned over, as much as his he could, and slowly drained one then the other breast. Now, each of her breasts fought for space with his stomach- forget a watermelon, he now looked as if he'd dined on a bear.
Peter grinned and patted the stomach (as best he could, as he couldn't completely see it beyond his oversized pectorals). As before, but much more slowly, it began to deflate as his overstuffed bod's hyper metabolism went to work.
But before it had shrank even a quarter, something happened. His stomach began to emanate a strange rumble, shaking both him and Joce pressed against him...
What was happening?
