“Screw the five minutes, I want to be BIG!” Shigeru shouted. He grabbed the cup and filled it up with the red liquid again, and drank it. Immediately he refilled it and drank that. By the time Dr. Murray and his assistants rushed in to shut off the machine, he had drank eight cups in a row.
“Noooo!!!” Dr. Murray cried. “What have you done? Drinking that fast will cause the growth to speed up exponentially!! Who knows how big you’ll get!”
“Good!” Shigeru shouted, his voice rumbling the building. “The bigger the better!”
He felt the fizziness in his body again, but this time it was overpowering. Shigeru lost his balance and fell down, crushing the machine. He rapidly began to expand, quickly bursting out of his boxers. His legs shot out forward, and, even sitting down, his head hit the ceiling. His growth didn’t stop; instead it sped up. He rapidly grew through the ceiling
Shigeru kept his eyes closed as he continued to grow. The building crashing around him barely fazed him. He continued to laugh in ecstasy.
The fiziness finally stopped, and he looked around. He was sitting in the middle of downtown, completely naked, having destroyed several buildings around him. He stood up, rumbling the ground as he did so. He guessed that he was over five hundred feet tall now.
He felt a wet spot on the back of his upper thigh, and reached around to peel it off. It was the remains of Dr. Murray and his staff. “Serves them right,” Shigeru said. He laughed and threw their tiny bodies to the ground.
Being so unbelievably huge was a great thrill for Shigeru. Hundreds of people were running around terrified by his feet. With an evil grin, he lifted his foot and began to deliberately stomp on them. He loved the feeling of bones crunching underneath his foot.
Shigeru then looked up and saw the waterfront where the big buildings were. Smiling, he started walking towards them, crushing cars, people, and buildings along the way.
When he got down to the waterfront, Shigeru saw that even the taller buildings were not much higher than what he stood. He started hitting some of them, relishing his role as boy-monster. As he did so, his cock became erect. It was now forty-five feet long. Shigeru took it in his hand, and then got an idea.
He looked around for a suitable building, and found one that came up to his eyes and was not very wide. He reached up and grabbed the top of it, then rammed his cock into the middle of the building. Glass, wood, and steel shattered and flew everywhere, and Shigeru began to move back and forth, humping the building.
He quickly started to climax, and when he did, he pulled his cock out of the building and rapidly stroked it with his hand. He had several minutes of climax, until finally, the first shot leaped out, shot through three buildings, and landed in the park, coating it white. He had several more shots, each one more intense and powerful than the last, until he finally fell over, spent, and giggling.
