Suddenly the computer beeped. It showed three lines of timers and the first one just went to 00:00:00. "Ohh", said Jeff as he felt his body growing. As he did so his coloured plastic started to smooth and balloon in size. His proportions became somewhat less muscular as plastic turned into flesh, and doll grew into man. Looking back at himself he saw that Bill's body parts have changed with him, and that thought made his, well actually Bill's body rather erect. As the changes finalized he touched his new parts, which were clearly visible because of the slightly different skin colours and realized that these parts were now his parts.
Jeff, now a completely naked human centaur looked down at his friends who were still toys and picked them up, placing them at his desk, "I should have told you it's on auto-revert." "Didn't think what would happen when we switched parts", he added. Bill wondered, "So what are we going to do?" "Well I'm not sure I can do anything", Jeff said as he was looking at the program, he pressed a button an Bill's timer stopped, "except for delaying the change." Bill nearly cried as he thought about how he'd look back in flesh. "However I think we can just change back to plastic and swap our parts back.", he said and picked up Justin, pulling off his arms and legs before putting them in the correct way again, "You should try calling your extensions, let's see what happens when you change back".
Justin nodded, he didn't really want to, but considering he could experiments with his friends, it only seemed fair for them to experiment on him. He typed on his wrist-puter and spread his blue arms and legs into an X-shape just before he was bathed in light with elements of his kit appearing around him. At first 2 laser guns, clicked themselves into place at his lower arms. Then a rather large piece clicked itself into place, it was a powerful jet engine with a set of wings attached to them. At last a blue helmet shoved itself down over his head. As the light faded away, he relaxed his limbs, looking at himself standing on the desk."Cool", he said to himself.
Then the computer beeped again as Justin's timer went to zero. Jeff quickly picked up Justin and put him onto his bed. He knew that the table would be one of the worst places to be during the change. Gradually Justin grew in size with the plastic loosing both its colour and detailing. Looking at his arms, he realized that his guns seemed to change with him, changing not into flesh, but metal. Looking back he also noticed his flight pack still being there, as well as his helmet. As his member started to reshape this prospect of being both man and machine aroused him, making his member clearly erect. Eventually the changes were finished and he tried to pull off his helmet. "Hey it's stuck," he concluded, but managed to open the visor, "I wonder if I can fly with these." Jeff looked careful at Justin's back. His flight-pack was fused with his back with flesh turning into metal seamlessly creating a prefect bond. "Well no matter if they work, they are definitely a part of you now."
