Nick had thought about using the regression gun on Clark, as the whole thing was his idea. However, he had promised not to do that to Clark, and the last thing that Nick wanted was for Clark to retaliate and possibly break the gun.
Thinking about Clark's 'boy genius' comment back at the food court, Nick pulled out one of the jeans that he had just bought along with a plaid collar shirt that was also in his younger size. With not much time before Clark returns, Nick removed the t-shirt and shorts and put the jeans and collar shirt on. After remembering to tuck in his shirt, Nick took one look in the mirror and came to one conclusion: "Clark has a point. I can easily pass as a boy genius."
Clark returned to the apartment minutes later, and was immediately met with his recently regressed roommate. The boy's head was a few inches below Clark's chest. The 2 feet height difference made Nick feel every inch like the boy he had become, but Clark was elated about becoming one step closer to easy money.
"Holy shit, dude! That thing actually worked, man! Un-fucking-real! I ca-" Clark exclaimed before being interrupted by Nick.
"Language!" Nick shouted.
"Sorry, man. Ya know what I mean. I just can't believe it!"
"I get it, it's exciting and all, but you gotta set a better example."
"Fine dude, whatever," Clark sighed as he reached out for the regression gun. Nick obediently turned in the gun while trusting Clark not to use it for his own shenanigans. Their conversation continued as they walked to Nick's room.
"So, how did it feel while it was happening?" Clark asked.
"I didn't really feel anything. It was like, one second I had my maturity, but it disappeared by the next second," Nick said, "No pain or dizziness either, so no need to buy any of those kids medicine for me."
As soon as Nick's door opened, Clark had another question on his mind: "Nick, why is there a mess in your room? I mean, look at all these clothes."
"Well, since you said you'd help with most of the cleaning, I thought that I'd just leave that to you," Nick replied.
"Just because I agreed to take care of you doesn't mean I'm gonna pick up after you all the time."
Nick rolled his eyes after that response, which caused Clark to go down to his level.
"Okay Nick, you need to listen to me," Clark said with a stern, disciplinary tone, "You are the child, and I am the adult. As a child, you need to do as you are told. When I say 'clean the mess in your room', you clean the mess in your room."
Realizing that he gave Clark the regression gun, as well as the reality of the size difference, a shiver shot down Nick's spine. "Fine," Nick said, "I'll clean it. I'll make room in my dresser."
"That's good enough for me, but let me get one more thing before you start," Clark said before running back to the front of the apartment.
As soon as he returned, Nick's heart sank while seeing what Clark was carrying. A dissatisfied look spread across his face, one that Clark could hear in his voice, “Mannn, reallyyyy?”
"What's the matter now?" Clark asked.
"GoodNites? Really?" Nick whined.
"Well, you told me about your bedwetting problem earlier, and one of the last things I want to do is clean your piss-soaked sheets every night."
Breathing a heavy sigh, Nick got to work on sorting the younger clothes that he had recently purchased.
"Now if you excuse me kid," Clark announced, with Nick blushing after hearing his roommate call him kid, "I've got some grown-up stuff to do."
"You're just gonna hide in your room and jerk off, aren't you?" Nick asked, "So much for being an example."
"Hey, just because you lost all of your adult urges doesn't mean I have to as well," Clark answered, "I have to put your gun away anyway, but I'll be back."
Clark then closed the door and returned to his room, relieved to have a break from putting up with a much younger Nick. "Fuck, that kid is a piece of work," Clark whispered, "The $1000 better be worth it."
After locking the door to his room, Clark proceeded to his safe and opened it. Just as he was about to place the gun inside, a thought crossed Clark's mind. "How should I know what that thing feels like if I hadn't tried it myself?"
Clark poked around with the digital screen, changing the number several times. He wondered if it would be worth it to use it on himself. He thought about the possibilities.
While intending to always be older than Nick, Clark could turn himself back into a 13-year-old to take on the role of Nick's big brother. He wasn't far into puberty at that age, but he could at least get hard at 13.
Alternatively, he could make himself 10 years younger, becoming an 18-year-old college freshman. He could then pose as Nick's cousin while in public and still have his adult freedoms alongside his active sex hormones.
"Maybe I don't want to get younger," Clark thought as he entertained aging himself into his thirties. 38 sounded like a good age for a man like him to have a 9-year-old son. Nick would take him more seriously, and there was also a chance of a 38-year-old Clark scoring a single MILF while at the competition. Furthermore, Clark was fascinated at the thought of having a 'dad bod'.
"What to do, what to do," Clark thought as he pondered changing his age at all...
