Ty and Dustin waited a bit until a new boy walked up. Ty nudged Dustin and pointed him out, "I'm gonna grow him, alright?". Dustin gave the thumbs up.
The boy sat down on the bench and pulled out his phone. He looked to be 16, about six feet tall, and fairly lean, but athletic as well. He looked through the boy's shorts and saw that he was average down below. Oh well, what's another growth spurt, he thought and made the wish. He also wished that everyone would think this was perfectly normal, including the boy.
Luckily, the boy had spread his legs wide while sitting on the bench, giving Dustin and Ty a perfect view of what was about to happen. The boy was also wearing fairly tight but stretchy shorts, which meant the show was starting soon. As if on cue, the boy moaned out loud, and Dustin nudged Ty. Slowly, they could see a small hump forming between the boy's legs. While still small, Dustin and Ty were excited.
The boy continued to focus on his game, seemingly ignoring the tightening of his briefs. Dustin and Ty had a perfect front row seat. The boy's shorts continued to bulge outwards more and more, demanding more and more space. Ty estimated that the boy was packing the same length soft as he was previously hard, around five and a half inches. And still growing!
The boy kept playing his game, but automatically spread his legs even wider, giving his package more room to expand. And expand it did, continuing to slowly elongate. It looked to be over 8 inches completely soft, and thicker now! Ty and Dustin nearly died laughing when the boy's cock expanded so much that it popped out above the waistband. Annoyed, the boy looked around and quickly shoved it down one of his shorts legs. Then he resumed his game, ignoring the tubular bulge running down his leg.
Finally, Ty stopped the growth. The scene looked absolutely ridiculous - a normal boy sitting on the bench until you realized he had a gigantic outline of a cock running down his leg. It had to be a foot long, completely soft, and thick as his wrist. The boy just sighed in annoyance when he got up and walked away, walking slightly awkwardly. Ty and Dustin giggled madly.
