Of course.

This days dinner was a tepid but hearty stew of leftover roast beef with various vegatables, beans, and rice. His mother would never have touched such plebeian fare, but it was tasty and filling, so John couldn't complain. Some days he only got a sandwich and some cold soup, this was nearly a feast by comparison.

He was unusually hungry though, which reminded him of the "realism" he'd included in the rule that gave him the completely real equipment his stepsister was still pondering occasionally.
"I'll have to smuggle in some supplies later, or maybe make them appear via Rulebook...there's no way Jane will provide enough."

But he could deal with that later.
Right now, he had the curious interest of his stepsister to consider...

5 years ago, John had been riding high. He'd been the son of a powerful CEO, making connections and having fun at the parties his father's position got him into, and had plenty of women interested in keeping him company. He remembered the day he first met Jane, at a party his father held. He'd been stunned by her beauty, and even more by the proportions her body. He supposed it had been a mistake to hit on her, but how was he to know his father was interested in a woman whose age was closer to his than his father's? Although in hindsight his father's previous trophy wife should have clued him in.

He hadn't paid much attention to Barbi back then, she'd just been the 14 year old daughter of the newest women he lusted after, but he did remember she'd been far friendlier than her sister Cindi.

His father hadn't been pleased by his son's interest in the woman HE was courting, and John later realized the whole thing had been the first strike in his soon-to-be-stepmoms attempt to separate them - Jane didn't want the son everyone said was an idiot playboy to get between her and the real power. Her efforts over the next few years had gained her many an ally among the circles his father moved in, and John's painful realization that many of his "friends" (and his father's) were nothing of the sort had been a far worse blow than losing access to the pleasures he had enjoyed.

His father hadn't been doing so well as CEO those last few years, but the heart attack that felled him physically a few months before his **** had apparently opened his eyes to the threat his newest wife was to him and his son. He'd done what he could before he died, and one of the things his updated will made perfectly clear was that as few people with connections to Jane as possible were to have any say over the remains of his fortune. Jane had been livid over the changes, but the security his father had on his hospital room kept her out. And his **** revealed the fortune to be smaller than she expected anyway. Not that she was going to retract her claws out without a fight.

John didn't understand it all, and he'd thought his father had a better stockpile than apparently was the case. But whatever the cause, the years after his father's **** had shown him sides of his stepmom he'd not realized existed.
He couldn't say he hated her, he was still too attracted to her outward appearance to do that. But she was the enemy, and while he'd despaired of defeating her just a few days ago, he now had an...additional resource.
John had sworn to himself after his father's **** that he'd get out from under her control and figure out what had taken down his father's company. He had suspicions, but nothing solid.

John shook off the darker aspects of his memories and decided he'd launch the first strike of his own campaign with Barbi. She had seemed friendly back then, and the glances she kept giving the table over his groin meant she'd noticed his improved equipment. Although whether she believed it was real he didn't know.

But how best to approach this?
"Aidea, can I write a rule that indirectly alters my stepfamily, for example a rule that changes some aspect of the house in a way that then in turn changes them? It'd probably need to be something subtle, but..."

"You could, but remember that any significant changes, even Old Rules, will trigger the dormant rules some asshole put in place hundreds of years go."

"Hmm... I've been meaning to ask, why does The rulebook still have those rules...on the book, so to speak? Their authors have to be dead now, right?"

"Rules don't automatically end when the author dies. If worded right, they will stay in place until/unless countered by the rules of the current author, especially if they reference something that still exists."

Thoughts of centuries-long conspiracies and secret organizations waiting to pounce on unsuspecting Rulebook authors bounced around John's mind.
He mentally shook his head.
"You can't just drop a detail like that and expect me to ignore it, but I have more immediate questions."
"Can I write a rule that causes tiny hidden devices to be place throughout the house, devices that disperse invisible substances?"

"I can see what you're thinking, and yes you can. And additionally, it will work. But not on your stepmother, she is protected from such influences. Not alerted by their presence, but protected from their influence."

A plan of action in mind, John quickly finished his stew and got up from his chair. A playful thought caused him unlock his erection and stare at Barbi for a few seconds, letting his cock grow to half mast, stretching the left leg of his sweatpants outward slightly. He smiled at her badly hidden expression of shock and left the kitchen. He'd only let her see a hint of his new equipment, but he knew she was interested. He had a few hours until one of his stepfamily began serenading the basement with her pleasure - unless Barbi started early - but they didn't know about the soundproofing, and he smiled to himself as he headed down the hallway to the basement door.
