The fifteen year old Ty stood up, as he slowly started to regress in age. He shrunk from 5'6" to about 4'6", a foot shorter! His arms and legs were shorter, as well as his stomach and his chest. After he had slowly shrunk back to having the body of a ten-year-old boy, he noticed that his endowment had shrunk along with the rest of his body.
But as soon as the shrinking had stopped, he felt his little 4 inch penis grow back again to 7", which he had when he was 15. But then the penis got bigger and fatter and longer, and it grew to 13 inches, like the cock of an adult man! The site was absolutely hilarious, Dustin started to laugh as he watches his 15 year old brother shrink back to a ten-year-old boy, with the penis of an adult man!
"Oh Ty! Ha ha ha! Look at you!" Dustin roared, almost unable to stay on the chair from laughing!
"Wow! I look so cool now!" Ty said, with the voice of a ten year old kid! His voice had a really high pitch to it, so it was a memorable site for Dustin to see the little boy with the monster endowment standing there in front of him!
Ty tried to walk, but he had difficulty moving. His cock almost reached his knees, since his legs were so short!
After a good minute of laughter, both boys had to wipe the tears from their eyes. As Dustin had just caught his breath, Ty figured he'd take his change a notch higher! Of course, this was Ty! And he loved to exaggerate! So he decided to make his penis grow another foot, till it was 25 inches long and over an inch in diameter!
"How do I look now, Dustin?" Ty said, showing off his little kid body and his full-grown adult package.
Dustin almost screamed of laughter and almost lost his voice! Tears were coming down his eyes, as he saw how ridiculous his foster brother looked.
"Ty, you are such a clown!" he said, barely containing his laughter.
Of course, Ty loved putting on a show, he posed, he flexed his muscles, he walked around the room, swinging his endowment from left to right, shaking his butt with every step. He was like a model walking on the catwalk, showing off!
Then the five minutes were up, and Ty felt his body growing back to his 15 year old self, while his endowment shrunk back to its normal size.
Ty almost regretted it his time was up, but he figured that he'd have plenty of opportunities to put on a show again. Besides, Ty felt that now and then Dustin needed his own endowment worked on as well!
As both boys caught their breath again and they calmed down, it was Dustin's turn to grab another piece of paper which indicated the kind of change he would undergo.
It read:
You rule the court, you can look over a wall;
big and strong, you're over eight feet tall;
your photo hangs everywhere, even the mall;
you join the NBA, now go play basketball!
Dustin started to grow taller and taller...
