Johnny found a pair of denim shorts. They looked kinda small but at least it was better than going around with just his tight underwear. Especially when his chicken size balls were continuously coming out as he moved.
"It's pretty cool to be a grown up but I must find a way to turn back to my original age." He thought as he moved his thick legs through the shorts holes. "Yep, I was right. It's tight but at least it's not too tight to be uncomfortable. I guess I can use them until I found something more fitting. Now, it's time to look for my brother and his friends. I wonder if he would recognize me..."
Johnny was walking through the house's long hall occasionally opening doors to look inside. He didn't know but the shorts were making some changes on his body as he walked.
First, his butt started to swell, getting a steady but also spongy look. It was a perfect bubble butt and, unknown to Johnny, his hole was also expanding. Then his already thick legs started to thicken even more. He now has the best looking thighs you can imagine.
Finally, the changes moved to his genitals. His already massive balls got even bigger as new amounts of cum filled them up. His dick didn't lengthen too much but it thickened at the point it started to unzip the shorts. Johnny noticed an increasing discomfort and he looked down to examine his penis.
"Holy cow!!" He shouted when he noticed the changes that had just happened to him. If he was freaking huge before now he could be considered a monster! Johnny started to panic. He needed to find his brother! To return back to normal! To go out of that place!
