Tony was about to go find the shop owner when...
he felt a twinge of pleasure in his groin. Tony was scared for a moment that he was turned on by Ben, but he quickly realized that it was his own packet now taking effect. Before he knew what was happening, his dick had swelled so large, the button popped off of his pants and his zipper was forced down. His once average sized dick was now at least 10 inches long, 3 inches thick and still growing. It snaked down to just below his knees when it finally stopped. He couldn't believe how huge it was. He touched it, sending a shiver through his whole body, and the blood flowing into his new dick.
It was then that Ben came out of whatever trance he was in and saw his new best friend.
