"Okay, Dustin, stand back." Ty reached into the back of his mind and concentrated on making himself bigger. First, though, he made it so that no one would notice the change except for Dust.
The feeling was great. First, his feet got extremely large; they were about 35 feet when it was over, back to front. Then were his legs. They became colossal pillars. His legs also became very muscular. When it was finished, his legs were 80 feet tall. Next came the chest. It broadened and expanded to about 55 feet wide. When it was done, his chest was 100 feet tall. He also became muscular there. His arms, when it was finished, were 55 feet long, and also muscular. His head grew into proportion with his body, of course.
Finally cam the groin. His balls grew to the size of 4 beach balls (Each). His cock grew and expanded, so in the end it was 25 feet long and 10 feet thick (And that's just flaccid!) .
Of course, was Dustin saw this happening, he became totally aroused. Even though he was larger than the average guy, his younger brother was not at least 180 feet tall. Ty broke through the house. His clothes, unable to hold this giant, ripped down the middle, revealing this now sexy god.
"So what do you think, Dust?" Ty boomed. Both of the boys knew that even Ty's pinky finger could squish Dustin.
Dustin was awestruck. "Uhh, well..." Ty picked Dustin up and put him on his enormous cock. G.Ty( Giant Ty) stepped out of the ruined house, and looked down on the unsuspecting city. "Waa-waht are you g-g-going to do to me?" Dustin asked as he slowly changed back to his normal self. This happened not by Ty's powers, mind you, but some other force.
"Oh, I was going to show you the city, but never mind." G.Ty put Dust back into the house, changed him into the hot self, and left him there. He wanted to explore this minature city.
