This time it hits...Robert!

He falls to the ground on impact, but gets caught in the arms of his father. “Oh no, what have we done?” Bob questions himself and his daughter. Just then Robert’s eyes open. He has a blank stare in his eyes, looking to be in a lot of pain. His jaws crunches onto each other. All the muscles in his body start to flex in pulses. And then it happens.

First he body lengthens, reaching 6 feet, 6ft4, 6ft9, stopping at 7ft2. His t-shirt has crawled up his body revealing an already impressive flat stomach, much like his dad’s. It was obvious he had used the gun before on himself.

Next the muscles started to kick-in. First on his chest, ballooning the t-shirt up as if he was growing boobs underneath. Very rectangular, muscular and defined boobs. At the same time his shoulders and back widens, supporting the newly created slabs of meat. His flat stomach transforms, within an instant, into a six-, no eight-pack, leaving only his limbs in his older state. But not for long. The quads and thighs rip apart the Hawaiian swimming trunks, revealing his bright green Hanes boxer briefs underneath. His calves complete the new tree trunks that make up his legs.

In the top part of his body, his triceps and biceps expand out to extraordinary proportions, ripping apart the t-shirt completely. His own body has changed his t-shirt into a muscle shirt with ripped off sleeves. The veins in his forearms indicate the next transformation; ballooned up forearms compliment his upper arms. And with that, his transformation is complete.

Robert was still being held by his father, who used this opportunity to test his strength. But as soon as the transformation was complete, the 15-year-old teen stood on his own two feet. His massive new body reached his full height for the first time, bumping into the door frame with his head. Robert started to laugh devilishly.

“Hahahaha, you thought you could keep me under your control? Well, guess again! Who is the master around the house again?” he said as he flexed his 19-inch arms in Amanda’s and Bob’s faces. “It’s me, you assholes!”

“Oh really?” a strange voice behind Robert’s back said. Amanda and Bob couldn’t see who it was because Robert’s massive back was covering up their view, but the voice sounded familiar...
