“Beginning phase three,” the voice emanated from nowhere.
Charlie, by this point, had all but become addicted to the feeling of growth. Even though he was mostly naked, he could still compare his body to Lee's to see how it was growing. Without clothes, he was also able to see how much hair he was growing. His muscles already looked like he was a serious bodybuilder, and not a natural one, either. There was no way someone could be this huge without some outside help. Charlie figured that magic was at least safer than drugs, but he didn't mind the implication that he was now so huge that everyone would assume he was juicing. All he would have to do is flex in their direction, and they would surely be cowed.
Charlie was broken out of his daydream by the feeling of his briefs finally giving way. Despite his enormous pecs hanging ponderously in front of him, he could see that his cock was enormous. He hadn't even realized that it was hard, which it clearly was, as it slapped itself against his sternum.
At this point, it was too much. Charlie was so aroused that he had to jack off. He reached one meaty hand -- no, he would need two -- and started jacking the length of his pole. Even with two giant hands, there was so much length that he had to take extended strokes. He quickly started leaking copious amounts of precum, which he used to grease his shaft, making the journey up and down its length less difficult. In fact, since he was presently shrinking, his strokes nautrally became shorter and shorter, but it didn't bother Charlie. He was surprised at how aroused he was, and he could feel himself about to climax.
Before he got there, though, he heard a gasp from Lee as Lee's shirt began to rip. For the first time in several minutes, Charlie appraised Lee carefully. Since Charlie was accustomed to comparing himself to others, he could judge quite quickly that Lee was about 5'10 and perhaps 180 pounds. Charlie was shocked at how much Lee looked like Charlie had earlier that day, albeit a bit smaller. However, one main difference was that Lee seemed to have quite a bit more facial hair than Charlie had, although less than Charlie had in his current hirsute state.
All in all, Lee had just about doubled in size since starting the process. Charlie furtively glanced at the tanks and saw that his own tank was nowhere near twice as full as Lee's. Charlie couldn't explain why this would be, and he was too self-absorbed to have figured it out by now, so he baited Lee into supplying an answer. “I don't feel much bigger than last time," Charlie grunted nonchalantly, trying to gauge Lee's reaction.
“Yeah, I didn't grow as much that last round, either,” Lee said quickly. “I think there must have been less of the magical growth-y stuff,” he added, but even he seemed unconvinced. It seemed unlikely that Lee didn't know what was going on. However, Charlie still seemed to be growing, and by now he had a deep need to continue, so he tried not to let it bother him.
