Kent looked pretty silly playing with a couple of young boys making sand castles. In fact, with his enormous cock, it looked a bit obscene. Ty was tempted to age the boy up, but realized Kent was happier playing games. He was still a child in his head. So as the super-stud thrity-year old man helped the boys build their new sand castles, he started shrinking, losing mass and size.
25, 22, 20... Kent dwindled quickly his swimsuit changing to match his dropping age. His monster cock shrank proportionally, so even as Kent dropped to age 15 he was hung better than almost any grown man. 14, 12.. the change slowed and then stopped as Kent became a slender ten year old like the two boys he was playing with. His sexual equipment shrank dramatically as he passed backwards through puberty, but remained a sizable bulge in his speedo.
The three boys laughed and worked together on the sand castles, no longer remembering that Kent had been a grown man just moments earlier. Ty grinned and watched them play. So happy. He made a minor adjustment, one that wasn;t visible. The boys continued playing, three ten year olds. And so they would remain, mentally and physically happy children, unless Ty removed the age lock he had just placed on them
