Invisible Ty smiles as he sees his friend Tim from school walk through the doors, wondering what just what he was doing in the gym. Tim was fifteen, just like Ty, but he was slightly underdeveloped and relatively skinny. He had very little muscle, and he mainly came to the gym to pedal on the bike and to stare at the big muscle dudes, as he spent his time dreaming about growing big like them some day.
Ty took a peek into Tim's head to see just what he had in mind when he looked at himself. Ty had anticipated seeing something along the lines of himself or Peter: Strong, like an athletic 15 year-old, but he wasn't prepared to see what Tim actually had in mind. He had been coming here with a picture of what he'd like to look like ten years from now at 25!
When Tim walked through the doors of the large, indoor weight room, he was immediately met by the owner, who was tall and muscular. In fact, the owner was just walking out the door when Tim walked in. Tim almost bumped into him, for the muscular man didn't even see him.
"Excuse me, my friend..." the bodybuilder said, as he made his way out the door.
Tim just stood and stared back at him, feeling a bit envious. He saw how big and muscular the man was, and he silently wished to be just as big as him, or perhaps even bigger! Ty was able to read Tim's mind, thanks to his wonderful powers, and he knew exactly what kind of body Tim had desired.
"Ahh... Let's have my powers work on his body as soon as he walks into the locker room..." Ty chuckled to himself. Ty concentrated on Tim and made him want to stroll to the men's room. "Time to make his dreams come true!"
Ty chuckled quietly to himself as he hopped down from the stationary bike and followed Tim to the locker room. He stayed far enough behind Tim, that Tim would never notice that he was walking right behind him. Ty wasn't about to miss this!
Tim dropped his bag on the bench and fiddled with the combination on his lock. As he dialed the last digit, a strange feeling came over him.
"What's this?" Tim wondered out loud. "Maybe it's something I ate?"
Tim quickly turned around to face the large mirror, which was hanging from the wall, right in front of the long counter where there were several sinks installed.
The strange, warm feeling had gradually intensified, as it spread over his entire body.
"What's going on?" Tim thought to himself.
A slight panic set in, when Tim realized that he was unable to move, while the tingling feeling grew even stronger, especially in his muscles. He was unable to move his feet!
Tim gasped out loud when his pectorals began to fill out his t-shirt, stretching the fabric to the point where threads started to break.
"Oh no! My shirt! I'm bursting out of my shirt!" Tim exclaimed.
His pectorals inflated even more, causing his shirt to rip in half, starting from the collar and working it's way down to the waist. Then, a thick layer of hair covered his chest all the way down to his torso.
"Wow...." he whispered to himself.
Next, his arms became thicker and thicker, while his biceps, triceps inflated at the same time. He ripped through the short sleeves of the shirt, laterally leaving the t-shirt hanging from his neck as shredded paper.
His abdominals expanded while his torso widened at the same time. Massive layers of muscles formed over the stomach, which was once flat as a board. Abdominals popped up in neat rows and columns, like tiles in a bathroom. The stuck out like large buttons, as they formed several rows of rock solid muscle.
"What's happening to me???" Tim shouted.
Next, his quadriceps grew thicker and longer, to the point where they were each one was as thick as an outdoor garbage can. Several layers of muscle formed over his legs, followed by long, red ropes of veins. His calves inflated to the size of soccer balls, sticking out so far from the back of his mighty legs, that they caused the socks to tear!
As his quads increased, he tore through his shorts, leaving him standing in his jockstrap. Then, his butt grew larger and harder, stretching his jockstrap to the max, before the strap snapped and caused his jock so rip apart.
Tim was standing alone in the locker room, and he was now butt naked, with only his shredded shirt, shorts, and socks hanging from his over inflated muscular body. In fact, his shoulders had grown over 6 feet wide, making his head almost seem ridiculously small, as it sat on top of this giant, oversized body!
"Holy cow! I'm a MONSTER!" Tim gasped, as he stared at the reflection of his 6 foot 6 inch body, which had 270 pounds of rock solid muscle added to his frame.
Lastly, when all the tingling had stopped, the strange sensation now concentrated on the last part of his body, which had yet to grow. His manhood!
"Oooooohhhh" Tim moaned, when he felt a powerful tingle in his cock. "That feels so goooooddddd..."
His 5 inch manhood grew longer and longer at first, stretching to 14 inches in length. Then, the whole penis inflated, and grew from an inch to almost 3 inches in diameter! He was enormous!
Then, the growth had stopped.
Ty was using his powers to "see" through the locker room wall. He just grinned, as he realized the result of his powers, which made Tim's dream come true.
"There ya go! You're all set, Timmy!" Ty grinned. "I just need to give you some bigger clothes...."
Ty's power went to work right away. His shredded shirt suddenly grew back, easily covering Tim's huge chest and torso. The sleeves were repaired, and the long tear down the middle was suddenly mended back, forming a new, large shirt.
A new jockstrap formed on Tim's waist, followed by a new pair of shorts. The shorts had transformed into a super-stretchy set of spandex, which always revealed the outlines of Tim's bubble butt in the back, and the huge softball-sized bulge in front.
"Whatever you wear over your waist will change into spandex from now on" Ty giggled. The shorts transformed into black spandex.
As Tim slowly walked out the locker room and into the weight room, he passed the large muscular man, who had bumped into him before. This time, Tim was bigger than him.
"Oh, excuse me, my friend..." Tim chuckled, as he looked down at the smaller bodybuilder.
The owner stopped and stared at him in confusion. Somehow, the large muscle man looked familiar. Had he seen him before?
Tim laughed while he worked out, as every other guy in the gym was staring at him. He was now 25 years old, and he was by far the biggest guy in the gym.
Ty just observed from the distance and laughed.
"Who should I grow next?"
