After changing his feet and his penis size, Jim was so excited about changing his body parts.
"I have an older penis now, and I changed my feet size... Then I will change my feet age!" he thought while he hold his dick with his hands.
"Control my feet age!" He said and then he blew into the balloon. His feet began to grow again but now, they grew some hair on them. His toes also changed, becoming flat with a sutile change on his nails color. Finally, a small odor became to be produced from them. "These are my father's feet for sure!"
Jim put his hand over his older feet and he felt a weird sensation. Touching and older part of your body with a younger one gives him a feeling of being two different people. He thought in a way to solve it.
"Control my hands..." Then, Jim thought. "Why to change just my hands... Control my arms age!" And then he blew the balloon. His arms became larger. On his kid's body, they looked like gorilla's arms. The muscle began to grow as he developed a very well toned condition. The skin on his arms, like on his feet got a slightly darker color and lose its young shine and texture. Finally, hair started to grow, it wasn't too thick but clearly visible. Jim felt an unconfortable movement on his armpits due to the hair growing there. He put his arms on to let the bushes to grow without problems. It was funny to see his hairy armpits next to a flat, pale and hairless chest.
Jim could feel the energy moving through his arms.
"Ok, these hands will be good for jerking off!" He said and then he masturbated over the carpet.
