Exercise regimen

He pushed himself impatiently through a week of crunches, scrutinizing his body in vain for any effect. Then on the sixth day, as he rubbed down his tall, sweaty body in the shower, he realized that he had gotten so accustomed to looking at his now-constant boner for width that he hadn't realized it had gotten longer! Holy shit—it had to be almost 2 inches longer! He came explosively right then and there, all over the shower curtain.

He almost didn't make it through the month—a 16-inch slab of constantly hard cock the width of his whole hand was almost too much cock even for Tommy, who loved his boner more than anything. He spent all of Day 31 sucking himself off, reveling in the size and sensitivity of his slab.

Feeling that his timing was perfect he moved on to the next of Rusty's exercises, deep-knee bends. Again he was perplexed at first—the first week seemed to have little effect other than tightening up his legs, a little, and by the tenth day he was starting to worry that he was doing them wrong. Still, past experience had made him a believer, so he figured he might as well see it through. And there was the strange sense that something was—pending. His legs were tingling, like something was building up. And finally on the fifteenth day he suddenly felt everything accelerate—he pushed himself through five more reps than usual and suddenly he collapsed on the ground, his legs feeling like they'd exploded! He felt dizzy and nearly blacked out, his head pounding madly. He leaned back on his hands, waiting for his vision to clear.

His legs felt weird. And when he could see again steadily he realized why: he was looking at three of his genetically huge feet. He rubbed the center foot against the others experimentally—he looked closer an realized it was another left. He ran his amazed eyes up three long sinewy legs. And where they joined his body, just below his still-narrow waist—two crotches! Out of each of them was standing his monster constant boner—he now had two of them! Fuck, he thought, and only one mouth. This may not be a good thing. The three legs felt great, though—amazing—but three legs and two monster hardons was enough. That was enough of this exercise!

Wow, what would the jumping jacks do? Could he even do jumping jacks anymore? He smiled and maneuvered his left superwide monster cock into his mouth, wondering what the next month would bring.
