A middle-aged man went to work-out in the gym and he dropped off his 11-year-old son at a class which was
located in a separate room at the facility. Moments later, just as Ty went to the boy's room to pee, the boy
also walked in. Both Ty and the boy were standing next to each other at the urinals.
Ty decided to use his powers and to have some fun with Joel, the 11-year-old boy, who had short, spiky hair
and brown eyes. He was wearing a tank top and shorts with tennis shoes.
Ty saw the boy's 3-inch cock and decided to make it bigger, but then he paused. What if he let the boy's own body control its size? But he decided to have fun with the boy and made his wish. Below Joel's cock, his balls began to swell up from their old grape size. They passed golf balls... then tennis balls... then baseballs... finally stopping at a large softball size. They looked enormous and out of place on Joel's skinny short frame, and when Joel pulled up his shorts, the front was massively bulged out and barely contained Joel's two huge nuts.
As Joel walked towards the exit to the bathroom oblivious, Ty wished for him to freeze. Joel froze in time, and Ty walked around him.
"Now let's see how Joel ages when he has a magic boost in testosterone! Joel, I want you to age one year every 30 seconds for the next five minutes! Oh, and lose the clothes!" Ty calculated in his head, that would age Joel up to 21. He settled in to watch the show. "Annnnnd go!" he started the clock.
Instantly Joel's new huge balls produced an enormous amount of testosterone, and the changes in Joel's body were almost immediately noticeable. Peach fuzz quickly grew into his upper lip, spreading around his face. Body hair began to thicken and appear, particularly around his cock, which had already grown out to 4 inches.
Ty also noticed Joel wasn't so short anymore. As he passed 12 years of age, Joel's head slowly began to rise as his legs grew longer and became more muscular. Joel had already cleared 5'3, which meant he had grown 4 inches from when he had first entered the bathroom! And as Ty watched, Joel's head met his level for a moment before continuing to rise.
Now 13, it was clear Joel was in the throughs of puberty. An adam's apple defined itself on his throat. More hair spread around his body. Joel's cock also grew another two inches, coming out to 6 inches. However, it was still dwarfed by his titanic nuts, which were also growing as he matured. Suddenly, Joel's rate of growth quickened, and he passed 5'10" in height. A ripping sound was suddenly heard, and Ty cursed as he realized he had forgotten to remove Joel's shoes.
14 came and went. Joel was now 6'1 and towered over Ty. His cock was now 8 inches. His Adam's apple became more defined. More body hair presented itself around his body. Joel continued to shoot upwards. At 15, he sported a full on beard (that Ty wished away promptly). At 16, he reached 6'7". His cock grew another 3 inches, stopping at a massive size just less than a foot long. By 18, he was 6'9". Joel's head was dangerously close to hitting the ceiling.
Ding! The clock stopped. Ty stared in awe at the towering college-age boy in front of him. Joel was no longer a baby faced boy, but a basketball player in his own right.
