Ty was feeling very happy after he was able to increase the size and muscles of another kid in the gym. It just seemed the most amazing thing he was able to use his cool, new powers for. Just the sight of seeing another person’s muscles inflate gave him such an enormous rush! Plus, with the person having no control over the size of their muscles while Ty was in charge of the growth spurt just added to the euphoria of growing other people’s muscles even more! Ty could make them as big as he wanted and there was nothing stopping him!
So, Ty wandered around the large gym and came across a room with only ten machines in it. Each machine was numbered, and there were few people in the room. He went to go look at the first machine, which was the leg extension machine, when a friendly young man walked up to him.
“Hey there! Checking out the express room, huh? I love working out in here! You can get a full workout just in this area alone!” the teen said.
The teen wore a shirt with the word “Staff” on it. He was about the same height as Ty, but he was skinny with blond hair.
“Oh, that’s cool. Gosh, thanks for the tip, uhh… What’s your name?” Ty asked him.
“Hi! I’m Miles. I work here.” The teen replied.
“Nice to meet you. I’m Ty. So, this is a nice place to have a workout?” Ty asked him.
Miles explained the purpose of the room and he explained how the ten machines worked as well.
“Sweet! Thanks for telling me all this. But you’re not very muscular yourself! Why is that?” Ty asked him.
“I have a hard time putting on muscle. I’m really skinny. I guess I need to eat more. I guess I’ll put on more weight and muscle… eventually!” Miles sighed.
Ty frowned where he heard that and made a silent wish.
“Eventually? How about you blow up and become a teen bodybuilder… Right now?” Ty stated.
Just as Ty hard ordered, Miles’ muscles began to inflate immediately! His calves ballooned from the back of his legs into large mounds of rock-hard muscle! His quads doubled in width as well, filling out his slacks completely! Even though Miles was wearing long pants, his sudden, big, inflated leg muscles were clearly forming the outline of his slacks after they finished growing!
“Oh, man! What the heck? Uhhhh!” Miles groaned as he was experiencing the biggest growth spurt ever, while Ty looked on with delight.
Next, Miles’ torso began to widen considerably. His flat stomach suddenly sported the biggest, most well-defined abdominal muscles ever! They were much bigger than any abs that anyone else had in the whole gym! The big, ripped abs were clearly visible as they pushed up against the boy’s gym uniform.
His upper chest and shoulders grew bigger and wider, with huge lats which gave him the most impressive V-taper. His shoulders ended up twice as wide as his waist! Big, thick and round pectorals were now hanging from his frame. He looked like he could bench press a truck!
“Whoa! Holy smoke! My muscles! I’m growing! Ohhhhhhhh!!” Miles groaned as his muscles continued to inflate all over his body.
Finally, his arms exploded in mighty pythons of solid muscle with large biceps and triceps forming all over each arm, finishing up with forearms as big and thick as bowling pins covered in veins. In the end, Miles looked like a teen bodybuilder who had spent every day lifting heavy weights in the gym.
Ty was very pleased with the result! He was getting aroused just by watching Miles’ muscles explode.
“What’s happening? I’m massive! Great Scott! I’m incredibly strong!” Miles gasped, looking down at his impressive body when the growth spurt finally ended. Ty grew him just enough that he didn’t burst out of his gym uniform. “Whoa! I can help so many people right now! That is awesome!”
Miles’ selfless comment just made Ty’s heart melt. He fell in love with the boy. He wanted to make him even BIGGER. He wanted to get to know him even more.
“Hey, Miles. What are you doing after work? Wanna hang out?” Ty asked him.
“Uhh, sure… My shift ends in thirty minutes!” Miles replied. “Wow! Did you do this to me?”
“Yeah! Glad you like your new, big muscles!” Ty smiled. “I wanna get to know you a little more!”
Miles and Ty then walked into the locker room where Miles just smiled as he walked up to Ty and gave him a gentle embrace.
