Jake stared at his phone. What size should he choose for his cock? He now had complete control over what size it was at any given moment (for the next 24 hours at least). That meant that he had a day to find the perfect size and set himself up for life. Jake didn't know what that was, but he knew that it was probably bigger than 6 inches.
Looking back at the app, Jake knew that he didn't want to be a shower. He tapped the erect length slider and upped it again, to 9.2 inches. But before he hit Enter, he paused. Was that really big enough?
Jake knew a boy at school with a massive penis. Noah had been well endowed since the 6th grade. Rumor had it he was packing a thick 10 incher under his boxers, and he was a grower. That meant he outclassed basically everyone! Jake had at times wondered what it was like to have a huge package that always stood out in his clothes. Now he realized he literally had the opportunity.
Tentatively reaching for the flaccid length slider, Jake saw as it expanded. The slider ran across the screen, with numbers from 1-24. Jake would never go that high... right? Jake pushed that thought out of his head. He wanted to still have a reasonable size, but he wanted... a bigger reasonable, he decided.
Mind made up, Jake slid the flaccid slider to 10 inches. Then as an afterthought, he increased it two more, to 12 inches. Might as well show Noah up while doing it, he thought, and a foot long, that'll be awesome. On exiting, the app notified him that to comply with reality, the erect size must always be at least as big as the flaccid size. Jake tapped the erect slider and dragged it to 14 inches. Might as well brag about being hung like a horse, he thought.
Below those two sliders, Jake tapped the ball size slider. A new slider displayed with the 8 options shown earlier. After reading carefully, Jake decided to go with 6 (Baseball-sized)... he wanted slightly bigger balls than normal at that size. Making sure that the app couldn't complain about his selections, he hit save and was about to hit Enter, when he had a fun idea. Jake pulled his boxers back up, he wanted to see his cock really grow. Before he could have second thoughts, Jake pressed Enter.
At first, nothing happened. Jake was beginning to think it didn't work when he felt a slight tingle. His balls began to swell, pressing the fabric of his boxers out further. Starting out at ping pong ball size, they inflated, first to the size of golf balls, then the size of eggs, then tennis balls, and then beyond before finally slowing and stopping. The sight was amazing. It literally looked like Jake had taken two of the largest baseballs he could find and stuffed them into his boxers.
Then, his shaft began to get fatter and longer. Jake watched with wide eyes as a new bulge emerged above his two enormous balls, first still small but growing quickly. Then his cock poked out of his waistband. It was fully erect and probably stood about 8 inches long at this point, but as Jake watched, it slowly added another inch. It kept growing out of his waistband, almost like a tree that had taken root in Jake's groin. It reached 10 thick inches, the same as Noah's, but it continued growing. Jake was mesmerized. He didn't realize a foot long dick was... well, really a foot long. Finally, his long shaft reached its maximum size and stopped growing.
Jake stared down at the monster python cock that was attached to him. Despite its enormous size, it stood rock hard straight up, all 14 inches of it quivering proudly and just waiting to be touched. But as much as Jake wanted to do that, he knew he had to go home to fully experiment. The mall was not the best place. Unfortunately, Jake also realized it would be difficult to hide his 14 inch boner. How would he get home?
