The Incredible Hunk

K-T wasn't really a gym rat, he was 6 feet tall and his rather lean body was only showing slight hints of muscle under his often tanned skin. Not exactly what people imagine when thinking about a superhero.

He was current in a remote forest area with his mom, dad and sister. His parents were wearing civilian clothes rather than their superhero outfits.
The twins had recently been chipped by the league and now a few months after their 18th birthday they were eager to finally get their powers.

His dad had them rn, jump climb and exercise, it was one known way to activate powers for the first time.

With the heat of the exertion K-T had ditched his t-shirt, only keeping his shorts and shoes on, Emily his sister was wearing a swimsuit looking leotard.

"It's not working Dear, they have been at it for hours," said his mom.

"Well, maybe they are not ready yet. Do you really want to use this? Shouldn't they get to have their powers emerge naturally?" replied their dad.

"Better use it and be done with it. You know that if it takes them too long to activate it they will always feel like they are behind others in the League."

There was a way to quicken power activation, a gas developed by a mad scientist to create super soldiers, had the unexpected side effect to trigger powers in those that have yet to get them.

His mother took a small canister from her pocket and threw it at the feet of the twins after pulling a ring from it. His dad clicked a button on a small remote that would send a signal to they chips.

The forest clearing filled with pink smoke and K-T felt power surge through him. His body was feeling like he was on fire. He was feeling dizzy and didn't pay attention to the weird ripping sounds around him.

When the smoke dissipated and he could open his eyes he noticed something strange.
His parents and the trees around him had shrunk down a bit. He began to fear that he got the power to shrink things around him a bit, a rather useless power.

He soon realized that nothing had shrunk when he looked down. It was him who had grown and bulked out. He was now standing between 8 and 9 feet tall, his hair had turned neon orange, his skin had the color of the fake spray tan used by body builders and he had massive bulging muscles. It wasn't hard to guess that he just got a transformation that would give him super strength, endurance and resilience, but there was something he could have gone without.

His shorts and shoes were gone, shredded by his growth. And he was sporting a massive boner, his cock usually 7 inches soft and 9 inches long was now longer than his forearm was before his growth, as thick as a soda can, the tip the size of his fist and he had balls the size of baseballs dangling under it.

Realizing his situation he tried to use his now massive hands to hide it, but it was pointing forward like it was made of steel.

Knowing that the league chip would trigger his transformation automatically in cases of emergency could become a problem if his super boner wasn't a fluke and parts of his powers. Some heroes that had transformative powers wore special stretching outfits under their clothes to accommodate it, but he couldn't imagine what could even contain this.

So focused that he was about his new body, he hadn't noticed what happened to his sister.
