"Hmmm, okay, I've seen enough." Jeff said, "Let's swap our lower halves"
"what?'' asked Jacob.
"you heard me! Lets swap our legs and ass too, i dont like seen my cock between your legs"
Jacob gladly took his brother’s offer.
“Sure I’m down, how do we do it?"
Since Jacob agreed to the swap, Jeff had no other option but to show the Chronivac to his brother. After setting the change, but brother stood infront of each other, watching their bodies change. Jacob was 15 years old, two years younger than his brother Jeff who had a tall muscular tanned body in comparisson to Jacob who still had slender body.
Jeff was 6 inches taller than his brother and his legs were more muscular, but now, as the change took place, he could feel his legs shorten and lose muscle, his. Skin started took lose the tan he worked sonhard to get and short light hairs started to grow. Since Jeff was part of the swimming team, he had shaved his legs since he started to grow hair, but his brother wasnt and now Jeff watched his little brother grow taller and lose hair while gaining some muscle in his legs. Meanwhile Jeff became shorter.
When the swap finished, Jacob was admiring his new legs making his new 6" hard rock.
"Wow this is awesome" said Jacob " look at me, i feel like i could run a mile in a matter of seconds"
"Yeah? Well dont get too used to them, remember they are still mine" said Jeff raising his knees, getting used to his new shorter and skinny legs and his brother's 3" dick. ''now go take a shower or something before I change my mind"
"Wow thanks bro!"
At night Jeff kept hearing his brother moaning in the other room. He was really getting all the use he could out of his new dick. And. Made Jeffs new dick hard as a rock, the sole idea of hagint a much smaller dick than his little brother made him really horny so Jeff decided to check the chronivac to see what other changes he could make but was met with a notification.
“Duration of the current change hasnt been set, do you wish to set time now?"
Jeff kinda feel bad that Jacob was unlucky enough to get the short end of the genetic stick in terms of manhood. He thought it was best to just give him some time to enjoy his new penis, it was only temporary. Plus he secretly thought the whole situation was hot as hell.
So Jeff decided to let the swap last for a week.
" current change will be unalterable for the next 7 days, no new inputs allowed. 162 hrs, 49 mins 27 secs remaining”
