Jake looked at the sliders. He thought hard. On one hand, he wanted to go back to normal, maybe a little bigger.
On the other hand... he was a size queen. He might as well go big or go home, right? What was the biggest this app could do? Jake dragged the slider all the way to the right. The readout read "24 inches". As much as Jake was a size queen, he wasn't that much of a size queen... was he?
Oh hell he thought, and hit Apply. The phone beeped "Changes going into effect" and nothing happened. For a moment, Jake thought the app hadn't worked.
Then he felt it - a tingle went through his genitals, followed by the feeling of his underwear beginning to get tighter. A quick look down showed his underwear beginning to once again fill up with Jake's package. Already he was at his old size before he had started, but as he watched his underwear was already filling past that point.
Jake quickly blew past the average size as well. Already his underwear was once again starting to completely fill up. The fabric began to stretch, trying to accommodate Jake's growing monster package as it kept swelling up. Already Jake's penis was over 7 inches completely flaccid, and his balls were the size of tennis balls.
Almost curious, Jake quickly walked over to his dresser, his package bouncing with its newfound increasing weight. Quickly, he found a pair of looser boxers and put them on over his underwear. By now, the fabric was incredibly stretched out, like a balloon was blowing up in Jake's crotch. In fact as Jake watched, he heard a ripping sound. His underwear fell away, and his cock, freed from its cotton prison proceeded to hang down. It reached his knee, and as he watched it grew a little bit past his knee before finally stopping. Jake's nuts pulsed and expanded one last time to a size rivaling melons. Finally, the growth stopped and Jake stared at his new two-foot-long cock with a look of sheer pride.
Sitting down on the bed, Jake admired how his cock was so long that it actually ran off the edge of the bed and drooped down at the end. Standing up, it hung past his knees.
Jake was shaken out of his reverie by a knock on his door. Thank goodness it was locked, he thought. "Dinner in 5!" his mom called. The fog on his mind slowly cleared. He needed to figure out a way to hide his cock. Crossing over to his drawer, he pulled out a pair of his underwear and attempted to pull it up. Eventually after slowly and carefully compressing his cock into the front, Jake looked in the mirror. It looked like he had stuffed a basketball in his crotch and it did feel very tight in there, but it would hold for dinner. Putting on his basketball shorts, Jake started down the stairs.
