"Change it so I'm still dependent on diapers" Mike said finally.
"Seriously?" Jeff question with a raised eyebrow. "You really want to be back in diapers" he reiterated just to be sure he heard right.
"Sure why not? If I'm going to become a toddler then why not enjoy some of the perks. Besides no one really remembers their diaper days, I for one sure don't, so I think it would be an interesting and unique experience to see what it was like using them" Mike explained his reasoning.
"Okay then." Jeff typed diapers into the underwear box, effectively making it so his father wouldn't be potty trained at all.
"Anything else dad? This is your last chance" Jeff replied.
"Can you make my diapers Pampers, I heard that's a good brand. Oh a make it so I still drink from a bottle and sleep in a crib, and throw in a pacifier for good measure" Mike fired off in rapid succession. Nodding at each suggestion Jeff typed away, entering each specific change into the program. Once finished he turned to face his father, soon to become his baby sibling.
"Okay everything's set just how you want it, except for the duration of the regression which I made to last the weekend."
"That should be perfect" Mike nodded.
"You ready for this?" Jeff asked as his hand gripped the mouse, the cursor positioned over the accept changes button.
"Do it!" Mike stated as his son clicked the button. Three seconds later he let out a pleasurable moan.
"You alright dad?"
"I'm fine, I just felt this pleasurable...pulse just go through my entire body" Mike explained as he gripped the back of the chair for support. "It's the regression, its starting" Jeff commented. "Well it may feel weird but it's a good kind of weird" Mike remarked. Glad there was no pain Jeff steadfastly watch already clearly seeing the hulking man becoming younger with each passing second as his body went through a startling transformation. His pouch of a belly shrunk rapidly until it disappeared completely while his dad's clothes became loose on his rejuvenating form. In no time at all he went from his late thirties to his mid-twenties and was coming up on his late teens fast as the waves of youth racked his body. For a brief period Jeff got to see his father back in his prime, before the depression of his wife leaving him and the pressure of supporting a kid caused him to let himself go and gain weight. Then just as quickly the image was gone as the reversal of puberty did away with his beard and body hair as he returned to teenhood. But even that didn't last long as the 'shrink' spirt as Jeff took to calling it made Mike a preteen. Thanks to the moaning he was treated to the precise moment his dad's voice changed, returning to the boyish octave of a prepubescent kid. As his father dwindled back to early childhood his clothes now mostly lay on the floor save for his shirt which hung on him like a dress. Mike could help but start giggling at this point as he slipped further and further back in age, all traces of maturity now long gone. When all that remained was a toddler of three standing in front of him did Jeff notice something happen to his father's clothes. They shimmered before beginning to change. His pants vanished while his shirt shrunk to fit his new age. As for his briefs they floated back up his legs, morphing and thickening into a pair of Pampers crusiers size 4. He knew the exact details thanks to the Chronoivac.
"So dad, how to you feel?" Jeff asked after a few moments.
The toddler looked himself over, checking his new baby body and feeling the thick thick disposable diaper between his legs. He then looked up at his son with a huge grin.
"I feel incredible" Mike chirped in his toddler voice. "I can't believe I've really become a baby again, and that regression woo that was one hell of a ride. Let me tell you I would mind going through that again. I think I even had an orgasm during my second puberty" he boasted, clearly overjoyed with how things turned out. "And look I'm wearing a diaper" Mike said as he flaunted his padding by shaking his rear and making it crinkle. "Man I can't wait to try these bad boys out" he replied getting psyched for future accidents.
"I'm glad you're happy dad" Jeff said with a chuckle.
"I think Mikey is more appropriate now Jeff" Mikey replied.
"Yeah you're right. So Mikey what you going to do now that you're a toddler?" Jeff asked interested to know his regressed father's agenda for babyhood.
"Well actually I'm curious to see what you plan to do with the Chronoivac" Mikey admitted. "So I'm going to stick around and see what happens."
Deciding it couldn't hurt to have the three year old watch he proceeded to input his changes to his own profile. As it turned out Jeff decided to use the Chronoivac to make himself...
