Jeff suddenly realized that the time was going to expire soon for his “experiment” which he set on the Chronivac for the period for him to live his life as his younger brother Max’s penis. He was happy that his brother was already home at this time, since it was already late at night. This was normally bedtime for Max, but Jeff was always allowed to stay up a little longer since he was seventeen.
Max was relaxing in bed and reading a book with just one light on in his bedroom when he was overcome with an intense tingling sensation in his cock. The tingling became so intense, that Max started to sit up straight, and he was preparing to stand up and walk over to the bathroom when the tingling stopped abruptly. The Chronivac beeped on the table in Jeff’s bedroom, and Jeff’s body was expelled from Max’s cock, which explained the intense tingling sensation. Jeff popped up, buck naked, on his bed in his own room, to the sound of “transformation completed” appearing on the Chronivac software screen on his PC, indicating that the entire process of changing Jeff into Max’s cock and bringing him back again had been completed successfully.
“Whoa! Yes! It worked! It really worked!” Jeff cheered, as he ran into Max’s bedroom. “Hey, bro, how are you feeling?”
“Uhh… I had a weird feeling in my dick and balls. Why?” Max asked him, feeling curious.
“That feeling was because of ME!” Jeff pointed out to his younger sibling.
“What? What do you mean? What did you do to my dick?” the kid wondered.
“I was your dick! I was inside of it for the entire day, today!”
Max looked at him in disbelief.
“That’s impossible! Bullshit!” Max spats back.
“Oh yes? You were with Eric earlier today playing video games in your room. Then you rode your bike around. After that, Taylor came over and you guys played more video games. You even wondered if I could spend time together with the two of you next weekend because I got a bigger cock than either of you. Taylor doesn’t have any brothers, which is why he likes to come here. You guys’ love being naked, which is something he can’t do at his house since he only has sisters! I heard your entire conversation, you dumbass!” Jeff explained to his younger brother.
Max’s jaw dropped wide open. There was no other way for Jeff to have overheard all of that. In addition, Jeff wasn’t around all day long, so it made sense.
“Oh, so that’s where you were the entire day? You were my dick? Why didn’t you say anything?” Max asked him.
“I couldn’t! I didn’t set it up properly! This was my first time using the Chronivac machine and I thought it was a joke or something. Now that I know that it works, we can experiment with it some more and use it properly, next time!” Jeff explained. “Maybe we can use this when Taylor comes here, next weekend!”
“Ohh, sweet! Yes, we can make ourselves into part of his body. Or can he and I become part of you?” Max asked him.
“Of course, little bro. This thing has an unlimited number of settings and possibilities. I found a lengthy list of things you can set with the software. It will take a few days for me to figure this out.” Jeff smiled.
Max was already looking forward to his friend Taylor coming over. What would the boys do with Jeff and with the Chronivac machine, once they got it figured out?
