Jack was watching the little girl transformation from a safe distance and behind a bush. However, it wasn't a perfect hideout because he was suddenly hit by a ball. When turned back he saw a little boy approaching to him.
"I'm sorry, mr." Thd little boy who surely wasn't older than 6 years said. He was wearing an adorable little soccer uniform but to Jack's eyes he was just another one of those annoying kids that he dislikes.
"Are you alone?" Jack coldly asked.
"No, I'm playing with my friends over there!" The little boy said as he looked for his ball. Jack noticed that there was a few more little kids in uniform playing soccer.
"Perfect!" Jack thought while he smiled. "More kids means more infection." He made a quick wish before the little boy left him. "The virus can be transmitted by touching. Adults can have it but it'll only affect people under 18 years old. The virus effect doesn't start immediately, it could vary from a few minutes to several days but once it triggers, the growth is very fast."
The little boy found his ball and was leaving. Jack needed to act quickly. "I wish I was infected and, finally, it can be distinguished a newly grown up by these secondary effects. For girls their boobs and ass will be extra huge, and for boys they'll always be very masculine. I mean, body and facial hair, big muscles, big feet and, of course, big package."
"Good bye, mr." The little kid said as he walked away.
"Good bye, kid." Jack replied as he patted the boy's back. He made sure he touched the kid's neck with his fingers. He smiled satisfied but after a few seconds he realized that he didn't know when the virus will start on the boy. So, he made a last wish. "I can trigger an infection at will with my stare."
The little boy has just reunited with his friends when another kid told him that the man who talked to him was still looking at him.
"Maybe we should go." He said but before he could take a step he felt a sudden pain in his little privates like if he was kicked in there.
"Are you ok?" Another boy asked as he put a hand on him. He didn't know it but he immediately got infected by this.
"AAAAHHH!!" The kid yelled as his legs and torso immediately stretched rapidly to the size of 6ft. His feet bursted out of his small shoes revealing wide size 15 feet. "WHAT'S HAPPENIIIINGG!!!" He yelled again but this time his voice was way deeper.
"AAAAHHH!!" His legs grew muscular so rapidly that his pants immediately ripped off of his body. The other kids started to run away terrified while the boy went through 12 years of puberty and growth. His body quickly formed large pecs and abs that pushed against his once baggy uniform. His arms lengthened and grew large as thick biceps emerged in them.
"HEEELP!!!" He yelled but nobody came. He didn't looked like a kid at all. His hands had grown massive as well as his shoulders which had broadened so much that they ripped what was left of his shirt. His face went through so much change that Jack barely recognized the young boy he once was about a minute ago. He definitely was an almost naked adult now. However, there's something left.
Jacks stood in awe as he watched the former kid's package growing inside of his tight undies. Jack couldn't believe how big he was getting and stared fascinated at the growing balls and dick. They grew so large that they were pushing against the material of the undies to escape. The new man was desperately adjusting his underwear but he couldn’t succeed and it suddenly bursted out.
Jack kept watching at the 18 year old guy's huge package equipped with two large balls and a big throbbing cock. The young man immediately came all over his own chest and passed out with sweat all over his body from the rapid growth.
"I guess I overdid the manly part..." Jake said as he gazed upon the naked 18 year old hunk of a man laying on the ground. "I wish the next infected boys won't grow so big genitals. Above the average it's fine." He was staring at the still throbbing fat cock resting on the young man's thigh. "Sorry, kid. You were my guinea pig, so you will keep that monster between your legs." He started to walk away smiling and excited for what will happen during this month.
