Just as Liam was about to leave the store, he cursed. His brother was still in there! As much as Liam wanted to play with his new cock, he did still care about his family. He quickly ran-walked back into the store, trying to ignore his cock bouncing around his shorts (he would really need to look into some support for the beast).
Liam went to the spot he had been looking at cups. He smiled, knowing that none of them fit very well now. He began searching for his brother.

Dustin spied Liam looking for something a few aisles over. The boy looked slightly frazzled, and his hair was slightly matted down. Dustin guessed he had some fun in the changing room, and was about to find another victim when he realized: Ty had never set a maximum limit on the amount of growth. With that, he began to stare at Liam.

Liam was beginning to get worried. His brother was nowhere to be found. He kept searching, though he wasn't sure where to go next. As he was about to leave the area, his crotch tingled again. He smiled, thinking he was getting hard again. He looked down, but his eyes bugged out at the sight.
Liam could plainly see that his cock was not becoming hard. It was not rising up and there was no blood pumping to his cock. And yet, he could swear the outline of his cock in his still-too-small shorts was growing. Getting longer, getting thicker, and becoming heavier. And below his cock, he could swear his balls were swelling again, becoming huge...
Were they? His shorts were desperately fighting to contain his mammoth genitals, but they were losing the battle. A small rip was heard, then a larger one. Finally, Liam's shorts fell off, leaving Liam completely naked in the department store. He ducked behind a rack of clothes to hide, coincidentally also shielding him from Dustin's stare.
Now that he could take a good look, there was no question in Liam's mind that his cock had grown further from the changing room. His previous size in the changing room, 11 inches soft and 12.5 hard, had been huge! The cock that was now attached to Liam's crotch didn't feel real, because it dwarfed his old one. It had actually only slightly thickened, but it had lengthened quite a bit. Liam estimated an additional 4 inches of cock had been added, leading to a grand total of 15 soft inches. Liam's balls had slightly plumped up, and feeling them, Liam noticed they felt much firmer.
Dropping his cock back down, Liam snapped out of the haze and realized that he needed a way out of the store. Preferably with clothes. Looking around, Liam noticed a pair of Size XL track pants. The legs were huge, easily enough to fit both his legs in one hole. He quickly hopped to put them on. Strangely, he noticed that although they were much too wide, his legs actually were the perfect length for the pants. But he didn't have time to ponder that. Running, Liam quickly ran out of the store. Where should he go?
