Since they lived on the same street (Jake four houses to the right of Chris's, Dylan three houses to the left), it only took his friends a few minutes from when he called them to make it over to his house. He didn't tell him what they were coming over for, only that they were in for a "huge surprise." And when the door opened and Jake and Dylan saw a six-foot-plus naked version of their friend Chris standing in front of them, they were definitely surprised, so much so that both their jaws fell open in unison.
"What the-- Chris, is that you?" Jake blinked his eyes several times and rubbed them to make sure he was seeing things straight.
"Yup! What do you think?"
"Dude, you're huge!" Dylan exclaimed, his eyes wide open with excitement. "And naked!" he added with a giggle.
"Thank you, Captain Obvious," Chris said, rolling his eyes and sticking out his tongue.
"How did you do that?" Jake asked.
"It's this ring," Chris replied, holding his hand up, and noticing for the first time that the ring had actually grown along with him earlier, certainly an interesting development. "I got it from a strange man at an odd store a few blocks away from school. I just wished to grow bigger, and somehow it made me this way!"
"Cool!" both of his friends said in unison, eyeing the ring.
"Do you get like three wishes or something?" Jake asked, looking up at Chris with a hopeful look.
Chris shook his head. "Nope! I can wish as many times as I want. Watch this! I wish I were another foot taller!"
Instantly Chris began to grow again, his frame stretching out and his head getting higher and higher above his friends, until they were staring at his flat stomach, with his partially-aroused cock dangling not too far below.
"Amazing!" Dylan exclaimed. "Do you think you can grow others. Like us?" He almost seemed to hop up and down with excitement.
"Hmm, I don't know," Chris said. "Let's find out. I wish my friends Dylan and Jake would grow proportionately until they were as tall as I am right now."
Both boys felt a strange tingling all across their skin, that quickly spread to their muscles and seemed to even go down into their bones. They both started to get taller, their bodies filling in their clothes more and stretching the fabric out until they started to hear tearing, a sound which Chris was already familiar with.
Soon, they were both approaching Chris's height, having grown almost three feet in a matter of minutes. They stood back-to-back, marveling at their now-nude body, long having lost the last shreds of their underwear.
"Wow!" Jake exclaimed. "This is the coolest thing that's ever happened to me!"
"And this is just the beginning," Chris said with a wink.
