Jeff watched with curiosity as his shirt grew into an XXL basketball jersey and his pants became a matching pair of basketball shorts, His shoes expanded into a size 18 and a sweat band appeared on his head.
"Ouch!" Jeff felt an electric charge run through his body and then the changes began... It started at his feet as he felt them grow to fit the shoes. Then his spine cracked as he grew taller and taller finally ending at 6'5"! Then he began filling out, his calves grew large as his abs became more defined and his pecks pushed out.
"Woah" Exclaimed Jeff as his arms lengthened and his hands grew proportional to the rest of his body. The changes completed themselves as his face matured and his hair shortened. Jeff moaned as his groin completed it's own change growing longer and thicker until it was a hearty 10 inches long!
