Ty walked through the mall, looking for the perfect place to find someone to test his power on...
There! On a bench outside the arcade, there was a boy sitting, playing with his phone. Ty searched his mind and found that his name was Jack, and he was 14. Despite this, Jack was only around 5' tall. Ty searched more, and found that Jack was often bullied for his height by the other kids. Not for long though, thought Ty.
Jack was wearing spandex athletic shorts with boxers underneath, and judging from the bulge, Jack wasn't very big down there either. Ty searched and found that Jack had obsessively been measuring, but had only a 3" dick. Ty could change that though! Ty focused and wished.
Opening his eyes, Ty watched Jack across the mall. Then he spied movement between Jack's legs. His cock had begun to lengthen, changing the bulge from a round to a more tubular shape. As his cock grew in girth and length it became more obvious what Jack had inside his pants.
As Jack's cock passed 6 inches, his balls began to swell as well, creating two more twin bulges under his longer cock. No longer the size of small grapes, they began to steadily swell larger and larger, forcing Jack's legs apart to create more space for his new endowment.
At first clueless, Jack paused his game. He wondered why his pants felt tight, but then he looked down and gasped. Instead of the small bulge he was used to seeing, a long tubular bulge bowed out the front of his shorts, before starting to snake down his right leg. Upon inspection, it appeared to be growing longer! Jack also noticed that underneath it, two tennis-ball-sized balls had also grown.
By now, Jack was moaning from the pleasure as his cock continued to swell up, still fully soft, until it finally tapered off at 11 massive inches. Jack's cock hung halfway down his leg, and every detail of it, including the large head, was visible in the shorts. Jack's softball-sized balls took up what little was left in the shorts. Jack just stared, in disbelief and pure joy at having been bestowed with this massive organ.
