"I wish you were my little brother! A small and weak kid who can't mock me!" Ben shouted and for a few seconds nothing happened. Gabe started to laugh while he thought a way to punish his little brother for wasting his time.
"I told ya..." Gabe said when a sudden energy blast came out from the coin threw him back to the ground. That same energy vaporized his clothes leaving completely naked. Ben didn't flinched at all by the blast but he blushed when he saw his older brother's exposed body.
Gabe had an incredible physique with big muscles on everywhere, long arms and legs and a decent amount of body hair. But what took Ben's full attention were the dangling cock and balls between Gabe's legs. It was an impressive 8 inches dick covered in veins.
However, nothing of that last too long because Gabe started to shrink. His height reducing drastically, his muscles fading away until they're non existent. All of his body hair moving back inside his skin which now was limp and pale like baby skin.
"Stop it!!" Gabe yelled but he didn't have his intimidating baritone voice, he now has a high pitch that was so pathetic that made him embarrassed immediately. Ben ignored his words while he watched Gabe's size 13 feet reducing into small size 4.
Lastly, Gabe's proud dick began to shrink inch by inch. It was losing girth at the same time until he only had a 1.5 pathetic nub and thin as a pencil. His hefty balls were out of vision as they've shrunk and reattach to his abdomen.
In a matter of seconds, there wasn't any trace of the imposing man that Gabe was before, now he was just a pathetic little kid smaller and weaker than 12 years old Ben. He can't help it but he started crying like the little kid he was now.
"I can't believe it. It worked, the magic coin is real!" Ben said while he kept watching in astonishment at his brother in front of him. "Awesome!!!" He shouted in excitement.
"This is not awesome!" Gabe replied. He still didn't get used to how he sounds now. He stopped crying and stood up. "My beloved muscles are gone! I'm even smaller than you! I've never felt so humiliated in my life!!"
"It's not so funny being the little brother, isn't it?" Ben said with a confident grin on his face. He had never talked to his brother like that, but now he felt he can do it without regretting later. "But if you apologize for being a mean big brother maybe I'll turn you back!"
