Mike sat down and for being a luddite, quickly found what he was looking for. Obviously he was not the only one with the curiosity for it to be so easy to find. He made the modification to himself and his son and clicked submit making both of their genitals detachable, he deselected the default option of making the appendage fit the body, instead selecting to make the body fit the attached appendage.
While that was processing he went into Jeff's mental status and added the curiosity of what it would be like to have a piece of his father attached to him and submitted that change as well.
"That was easier than I expected." Mike said, signaling he was done to Jeff.
Jeff gave him a quick up and down. "I don't notice any difference, did you play with the reality settings?"
"Yes, but my... um, our... bodies aren't changing... yet..." Mike said hesitantly.
"Go on." Jeff said, intrigued and excited to hear what plan his dad has made.
"Well, this may seem strange but I made our genitals swappable..." Mike paused and Jeff just looked on with interest. "Our bodies grow and change so slowly and I never noticed what actually changed between being a kid and being an adult... one day I woke up and was legal, another day I woke up married, then a parent, and now you're almost an adult... it... well... I thought... Maybe... if you wondered what it would be like... umm..." Mike was at a loss for how to describe his interest.
"I think I get you dad... and I do wonder." Jeff cut in. "I still remember not wanting to grow up ever and birthday parties with piņatas, but now I can't wait for my beard to grow in, my muscles to get pumped, my adult height, and deep voice... I know that come tomorrow it will have happened 15 years ago and Ill be wondering like you... I guess, I can relate to how much things change over time, and being in the throughs of puberty, I am curious about what its like to be past this so I can appreciate it more as I'm going through it?" Jeff looked to the wall deep in thought. "If I knew what adulthood felt like, maybe I'd know when I'm there and I... I..."
Mike smiled, placing a hand on Jeff's shoulder, "Feel a little more prepared for it?" he offered.
"Yeah!" Jeff said with a heavy sigh, his shoulders slumped as he released the anxiety that had been scratching its way ever closer.
"Well, we can both see what its like on the 'other' side of time." Mike unceremoniously reached into his pants and an audible popping sound was heard as his penis detached. "If you want."
Jeff hesitated, he knew that this was big but it felt like such a small thing, after all it was reversible, and temporary, and what he wanted, right? Jeff thought back to his only reference of this situation, cartoons or movies where children grow up or swap places, but this was different. He and his dad were in it together from the start, and he isn't at risk of aging to death. Also, all those shows skip over sex, alcohol, and vacation getaways, and without those, what's the point of being an adult?
Jeff reached down, gripped his penis and pulled. With a little resistance his penis and testicles came off as a complete package along with some of the surrounding pubic area... "Yeah, lets try it." Jeff said nervously.
Mike locked eyes with Jeff and made a display of putting his hand out facing up. then his hand bearing his junk came out facing down. Jeff placed his hand under Mike's penis and pulled his own from his pants placing it over Mikes outstretched hand. The handoff was made and the exposed penises were quickly shoved into their new homes. The penises aligned themselves automatically as they snapped into their rightful position. Mike's original penis obviously had more heft to it prompting him to say, "I think you're winning."
Jeff chuckled nervously unsure what to say or do in this situation. "So, um... What's going to happen now and how long should we keep this up?"
"Well, ..." Mike began. " we still have the Chronivac, anything we like we can keep and anything we dislike we can undo, right? The purpose of this is to enhance our awareness right?"
"Right!" Jeff replied. "But I'm going to start being more adult, right? How will everyone respond to that?"
"Nobody's going to find anything out of place... However, your role and life might change as things progress... just go with it and see where you end up. Then go from there."
