Joce smiled again.
"I have a better idea." she said.
"What do you have on mind, honey?" her boyfriend said as he touched the ground again. The kids around left them alone magically.
"How about I made it where whenever someone rubbed your crotch, it would cause all your body to get bigger?" Joce said. "But this time forget about being a balloon. I know you love it, but if you are floating, people will not be able to reach your crotch. The more people rub your crotch, the more bigger you will get. What do you think?"
"Why do you ask that?" Peter said as he kissed her again.
"Ok then." Joce said as she happily avoided Peter's kiss.
Suddenly, Peter's body started to become smaller. All his muscles deflated, and quickly he discovered that he looked like a nine years old. Peter looked around, everything was bigger than ever. His girlfriend was very tall! He didn't know why, but he loved it. He continued looking at his new small body and discovered something even more interesting: his penis did not regress.
"Cool! I'm a little boy with an adult cock! Amazing!" he said with a childish voice. His crotch now showed a huge bulge on his black Speedo. He rubbed the bulge and enjoyed that feeling.
Joce, however, seemed to ignore his young boyfriend. He was calling the kids again.
"Whoah! What happened to your boyfriend?" one of the little boys said. "He looks like a kid now!" The boy was still younger than Peter, but now they were almost the same height.
"If you want him bigger, you will have to rub his crotch." Joce said to the kids.
"Alrighty!" one of the boys said. "Dude! I'd like to have one like you!" He approached to Peter and slowly rubbed his crotch.
Suddenly, Peter's body felt a tickling. He started to grow again, all his body became bigger except his penis. Peter closed his eyes and enjoyed the transformation. Now he looked like a 12 years old.
"Amazing!!!" the kids said.
"But he is still very small for me! Come on, kids, let's make him bigger!" Joce said smiling.
Another kid walked to Peter and touched his crotch. Peter felt again that tickling and his body changed even more. Finally, he became the teenager he really was. This time, the transformation made his muscles also bigger, turning him into a young hunk muscular man.
"Good job, Danny!" Joce said to the boy. "Who's the next?"
Another boy went to Peter and rubbed his crotch. He transformed again. He was getting bigger and bigger. In that moment he looked like a 20 years old, but he was taller and wider than any human.
"Huh... I feel BIG." he said with a new adult voice. The giant man flexed his biceps and did some poses.
Then the kids formed a queue and started to rub Peter's crotch in order. Peter continued to grow, but his body got too big for humans. No one could reach his crotch when he was almost 6 meters tall. He had to sit on the ground, kids started to play climbing his giant muscular body.
All the adults on the swimming pool joined the queue too. After some crotch rubbing, Peter became an incredible huge 50 meters man! Peter was stretched out on the ground, people could climb to his crotch thanks to a ladder. His penis was now a huge trunk on his black Speedo, when people walked on it he got even bigger. All kids were playing on his torso, using his pecs as a huge slide! Peter loved it.
When everyone on the swimming pool was above Peter's body, Joce climbed too and sat on Peter's left cheek.
"I love you, my giant." she said, and kissed the ground.
