As Jeff the baby continued to grow Ken decided to change the dog breed to golden retriever, since that was the type of pet he had as a young kid, that had died of old age around the time Jeff was born.
By the time Ken had hit 'Apply' a naked 5 year old Jeff was running around the room aging further with every minute.
Hitting 12 years old Jeff stood still and closed his eyes. Ken watched as Jeff's balls descended and blond downy blond hairs began to grow at the base of his now uncut growing member, spreading outward.
Starting to grow taller, hairs began to grow around his ankles and spread upward just as Ken decided to spice things up and blow once in the whistle.
Hairs were now pushing out across his body as he passed the 6 foot mark. Pecs and abs formed underneath the thick chest hair. His penis, how at its 16 year old size grew just a little more as the tip turned slightly pointed. A one inch tail pushed out above Jeffy's ass as his face grew a thin beard. Ears coming to a slight point and gaining a few hairs, Jeff licked his nose with a longer tongue.
The chronovac chirped complete and Ken wondered what he should do next...
