Walking out of the change rooms, Ty looked around for another boy to have fun with. Then he spied one! Waiting for shoes was another boy, around 13 if Ty had to guess. He looked to be a little on the small side externally, and he was wearing khaki shorts, a t-shirt and basketball high tops. He seemed relatively athletic.
The boy was sitting on a chair in the shoe department. He was busy playing his game. Perfect for Ty, who could just watch with no questions asked. Plus, the boy was sitting in the chair with his legs spread apart, giving Ty a perfect view of his crotch. He wished to be able to see through the boy's clothes and saw that his cock was about average size, 3 inches soft.
Ty turned around and wished that the boy's genitals would start slowly growing. Right away, he spotted a movement coming from the boy’s groin, as his cock started to grow longer and his balls started to inflate. Slowly the cloth of his shorts began to push out in a small bulge
“Uhhhhmmm” the boy moaned softly, while he desperately tried not to take his mind off of his game. He continued to focus on playing his video game while his cock elongated and his balls inflated some more. The tightness in his jock was steadily increasing and his shorts felt a little tighter as well, but he put that down to sitting for a long time.
Ty however could see why the clothes felt tight. Slowly the bulge between the boy's legs was growing, pressing out against the fabric more. Ty guessed the boy was packing around 5 inches soft now.
As the boy continued to play, he was trying to ignore the sensations coming from his groin. Probably just an erection, he thought. Absentmindedly he pulled the fabric up to try to cover his cock more, then returned to his game.
His cock however, had other plans. Still swelling in his shorts, it wanted more space and signaled this by pressing out more and more, occupying all the space in the front of the boy's underwear. Ty giggled as the bulge slowly grew bigger and bigger. The boy now had a pretty large cock for his age, and it was still growing!
The fabric of his shorts rubbed the boy's cock even more, causing even more pleasurable sensations that the boy was having a hard time ignoring. He tried to focus more and more on his game, desperately attempting to shut out the "erection" in his nether regions. Ty felt a bit sorry for the boy and wished that instead of underwear, the boy was wearing looser briefs. At once the tight fabric of the underwear let up on his cock and the boy visibly relaxed a bit.
Incredibly, the boy still hadn't noticed that instead of his normal cock, he was sporting a nine inch soft cock that was extremely visible in his shorts. He was shifting around constantly though, trying to relieve the tightness of his shorts over his enormous endowment. All the while, it continued to stretch out, swelling up and creating an even larger bulge.
10 inches passed, then 11, then finally the boy hit a full foot long soft. Ty finally wished the growth to stop.
The scene looked ridiculous. The boy looked completely normal from the outside, just like every other 8th grade student. However, his crotch bulged ridiculously, his underwear failing to completely contain his python cock. And he still hadn't noticed.
