Satisfied with the results of the last growth, Jake wondered who the watch would grab onto next. Fortunately, it didn’t take long before he felt another buzz on his wrist:
NEW SETTINGS DETECTED:
PENIS LENGTH: 3.7in
BALL SIZE: 2
EDIT? Y/N
Selecting Y, Jake looked around and saw an older teen, probably about 16 in the store. He was looking at athletic cups for baseball, and looked relatively athletic. Eventually, he selected a medium sized cup and headed back to the changing room.
Jake thought it'd be funny if the teen outgrew every cup he tried, so he quickly upped both settings to read:
PENIS LENGTH: 4.7in
BALL SIZE: 2
Hitting Apply, he watched as the front of the teen's shorts expanded into a small bubble, the teen barely felt the growth and continued to walk. Inside the changing room however, he discovered that he had grown! In confusion, the boy walked back out to the shelf and selected a large sized cup that actually looked a little big still for the boy. Well Jake could fix that... he modified the length setting:
PENIS LENGTH: 5.7in
BALL SIZE: 3
Before hitting Apply though, Jake realized he didn't want to wait for the growth. He went back and keyed in a much more aggressive growth:
PENIS LENGTH: 8.7in
BALL SIZE: 4
There, an 9 inch softie and tennis ball nuts, that would do it. Jake hit Apply.
The boy actually moaned out loud as his briefs struggled to contain his growing member. His cock quickly doubled in size to its new nine inch length, while his balls swelled to the size of tennis balls. The bulge in his shorts grew to be much larger and more noticeable. Finally the growth stopped and the boy looked a little dazed. He looked down at his crotch, walked over to the shelf and grabbed the largest cup they sold.
Almost dying of laughter, Jake adjusted the size once again:
PENIS LENGTH: 10.7in
BALL SIZE: 5
Instantly the boy's crotch began to swell yet again. His balls only swelled a little bit more, but his cock lengthened another two inches to rest at 11 soft inches. The boy was groaning in pain, his underwear was so tight. Looking around to see if no one was watching he grabbed his cock through his shorts and repositioned it so that it hung down one of the legs. It still looked big but at least it didn't hurt.
Now Jake took that as a personal challenge. Could the boy outgrow his clothes? What even was the upper limit of this thing? He hit the upper arrow a few times. Now Jake was frankly amazed it went this high:
PENIS LENGTH: 15.7in
BALL SIZE: 6
Hitting Apply, Jake watched as once again the boy's cock seemed to reel out of his crotch. He groaned as the head of his cock gradually dipped lower and lower until it actually grew out of the leg hole of his shorts, simply hanging there. Jake could actually see that the boy's cock was huge, his cock head alone was the size of a tennis ball! His balls had also grown to the size of softballs.
The boy tried to reel in his cock and stuff it into his shorts so that it didn't hang out, but there was literally nowhere he could put it. As much as Jake liked watching the struggle, he knew this was probably too much. The poor kid would struggle in life. So he sighed and tapped the down arrow a few times:
PENIS LENGTH: 8.7in
BALL SIZE: 4
Still a manageable size, he argued, albeit quite big. He hit Apply and watched as the boy's cock seemed to be sucked back into his body, the shaft rapidly growing shorter until it reached a still-amazing length of 9 inches. The boy's balls also shrunk back down to the size of tennis balls. It was still a monstrous package, but one that was at least manageable. Plus, he couldn't argue with the boy's new bulge in his shorts.
