"Hey, I think I'm going to take a shower" Jeff told his double (and former wank sock) as they walked back into the house. "Sure," Sock Jeff replied thinking that he could take the time Jeff was bathing to explore his body and new found humanity. After Jeff marched off to the bathroom the double decided to head to Jeff's room for some alone time.
"What's this" he thought to himself as he walked into the room. Sitting on the desk chair in front of the computer was a sock that looked identical to what (he figured) must have been his appearance as a sock. After a few minutes of reading through the Chronivac screen he was able to deduce the situation.
"So Carl, you wanted to be a wank sock" he mused gently rubbing the sock. "I think I know a better set of alterations if you want to eat a load" at this he turned back to the computer and began typing away at the Chronivac. Finally once everything was set the Jeff duplicate pressed enter.
Immediately his body began to shudder. His chest grew broader, his hair became a brilliant blonde, his height shot up 4 inches. What was once a Jeff duplicate had now become the spitting image of Carl. The duplicate smiled now and looked down at the freshly changed former Carl. "I'll put you to good use buddy don't worry, and as a bonus I'll use your body to do it".
The bedroom door swung open revealing Jeff fresh from the shower standing in only his undergarments. Startled, he jumped. "Oh Carl, I didn't expect you to be in here".
"Just thought I'd drop by" the former sock said oozing Carl's confidence and laid-back attitude. "I hope you don't mind, but I saw the Chronivac program open on your computer and decided to check it out. Then when your sock bro popped in, I just couldn't help but test it out on him. I think you could help me put it to good use." He held the former Carl up for Jeff to see, now a size Extra Large condom.
"Whad'ya say bro?"
