Jim looked at himself in a full-length mirror and smiled at what he saw. He was a handsome hirsute man, maybe a little too much hirsute but he didn't mind. He really liked how he looks.
He flexed for a moment and did several poses until he realized he was destroying what was remaining of his clothes. "I'm too big for this. Maybe I should look for some of my dad's... But..." He started to get a mischievous idea. "What if I become even bigger? These clothes would burst out of my body like the incredible Hulk!"
With the excitement of a little kid, Jim ran to take the balloon and then he used to change his size. He took a deep breath and blew into it.
FOOOOOOOOOOFFFFFFFF
He felt himself getting bigger, the room around him getting smaller and his clothes ripping the last seams that were still holding on his skin.
Jim was delighted with his new size but it wasn't enough he wanted to be bigger, bigger than the room, bigger than his house!! He tool the balloon once again and blew into it, this time even stronger than before. At the same time the balloon was getting bigger, so he was getting bigger too.
His shirt was completely destroyed and his pants followed it in less than a minute. Now he was wearing only very tight briefs whose seams were starting to give up. He can feel the fabric crushing his nuts but he didn't care because he knew he would outgrow them in a moment. So, he blew into the balloon again and his briefs finally bursted out.
At the same time his dick was jumping free from its constriction, his head was heating the ceiling, so he instinctively kneeled to be more comfortable, despite he knew he must destroy the ceiling if he wants to get bigger. So, he blew into the balloon again and his body became so big that even kneeling he was hitting the ceiling until he made a hole. His head came out through the roof, it should be painful but he was too excited to worry about it.
Then he raised his arms and the whole ceiling was destroyed, half of his body was above the house's walls, while his dick was on the borderline of getting exposed, but he wasn't embarrassed. He felt powerful! A powerful giant who can destroy a house with his own house! However, he still wanted to be bigger, so he took the balloon a blew into it one more time.
FOOOOOOOOOOOFFFFFFFF!!!!
This time he blew so strongly that his body skyrocketed in size. Now he was way more bigger than his house, he was even bigger than some buildings and old trees. Of course, he was so big that people nearby started to notice his presence and screaming in panic. It wasn't helping Jim that his manhood was fully exposed at the moment.
People started to run away, some other were taking pictures, videos and posting them in their social media. Jim even posed in a few of those. Meanwhile, the huge balloon was still between his fingers, ready to deflate and turn him back to his original size. He didn't want that, so he said "Release!" to seal his new size and then he let the balloon to fly away from him.
Jim can see the balloon flying through his town until it disappeared from his sight. He wasn't worried, he just smiled at the idea of living the rest of his days as a giant grown man. He only need to look for a place to stay, a maybe an apologize for destroying his parents' home. He cautiously walked away from his neighborhood to a near forest where he could find a new way to live.
