Of course!

I spent a long few seconds staring at Max. Considering.

Then, I realized if I couldn't trust him, I wouldn't trust anyone ever.

The grip I had on the book loosened and I flipped back to the very first page to show my twin the mysterious message and some of the Rules I had written.

Obviously, Max didn't believe me at first. I couldn't blame him, I didn't even tell him half of what I'd written. How could I tell someone they didn't exist an hour ago? Even the memories I had of that previous life were fading away like an unpleasant dream.

"Okay, here, let me try this." He watched with a worried look on his face as I flipped to a new page and scribbled a new rule.

[New Rule: Megan, The current Writer, can change the color of her hair and nails at will.]

He blinked in confusion. "Wait, you barely touched it, how did it print that fast–" Oh, yeah, time freezes when I write. Neat.

I shoved my hand into his lap, secretly enjoying the smooth warmth of his thighs and nobly resisting the urge to trail my hand higher— focus, Megan, not the time. "Watch."

Slowly, my chipped green nail polish turned to a shimmery blue that matched his widening eyes.

"Holy fuck." I grinned and pulled a lock of hair forward. After I glanced around to make sure no one was staring at us, the lock of hair turned a vivid pink. "Holy fuck." He said again.

I bit my lip and decided to trust him. "Here, write something simple."

Max held the book like he couldn't decide if he wanted to burn it or run away with it. "You're trusting me with this?" He gaped at me.

"Of course, you're my twin." I blushed and looked away from his face. "We're MegaMax." The silly superhero name we came up with as kids.

Max's cheeks pinked as well, he wiped his face and smirked a devious smirk. Uh-oh. I'm regretting this already. "Alright, something simple."

"Be careful to write a New Ru–"

As soon as his pencil touched paper he flickered and it was done. He yelped and stiffened in his chair. Max blushed redder than I'd ever seen and looked around nervously.

I settled back in my chair and crossed my arms, enjoying the shifting as my buttplug went deeper. I gave him a flat look. "You wrote an Old Rule. I have no idea what it was, it's always been true for me now."

He wiggled in his seat like he was uncomfortable. "Ah. That makes sense. It was a uh... Larger change than I anticipated." Max bounced on his seat and groaned with a sly smile, he shivered and bit his lower lip when he leaned forward on his elbows.

I narrowed my eyes, Max and I have been at the same size plug for a month, he shouldn't be acting like this.

"Aha!" I pointed an accusing finger at him. He shuddered and crossed his eyes when he jumped in his seat, only confirming my theory. "You made your asshole more sensitive didn't you?"

My smile fell as he choked in laughter.

"Yep! Something like that!" He devolved into giggles as I pouted.

He slid the Book back at me. On the new page I'd started–

[Old Rule: Unclaimed femboys and women wear jeweled buttplugs to show off their stretchiness and prepare for being Claimed.]

– stared back at me in black and white. How? The memories were seamless, I remembered our sisters and older classmates wearing them before they were Claimed, a tradition held by most cultures for over a century. Our Moms reminisced about it and wore them sometimes to feel younger. Max and I went together to get fitted and helped each other put them in the first time!

My minor existential crisis was temporarily resolved by Max pulling the book back.

"Hey, it's my turn!"

"I'm just gonna erase the rule I just wrote–"

"No!"

He stopped with the eraser hovering above the rule. Max's lips curled into a smirk. "No?"

"...Let's at least try it out for awhile? As far as I know we've been wearing them for over a year so..." I mumbled.

"What was that at the end?"

"...I like wearing them, okay!"

"Sigh, my poor innocent little sister, a buttslut wearing toys in public." He laid a hand on his forehead like he was gonna faint.

"You wrote the rule, genius! And buttsluts are proud members of society." I ignored the little sister comment, I kinda liked it honestly.

"...really?" Was that excitement in your voice big brother?

"Wouldn't you like to know? Unfortunately, I couldn't tell you, I've never known any different." I pointed out snidely. Wouldn't it be weird not to see Unclaimed actresses and celebrities showing off their real jewels on the red carpet? Madness.

Max flipped the pencil around. "Okay, let me at least reduce the discomfort here."

I barely opened my mouth to protest when it was done. I glared my best Annoying Little Sister Glare™ with my arms folded beneath my breasts.

Max slid the book back to me without complaint. A dazed smile on his face as he rocked back and forth. I can guess what he'd written.

[Old Rule: Humans' sexual orifices feel pleasant while being stretched to a maximum of the average width of a human's fists while interlaced. The digestive tract of humans is extremely efficient and self cleaning.]

Well, I can hardly complain about this one. What the hell were our butts like before!? They weren't clean? Ugh.

Max tilted his head at my disgusted face. "What? Do you not like this rule?"

"No, I actually really like it honestly. I'm just kinda grossed out at what it must have been like before..." Why didn't I change it? Did I like– Nope! Not thinking about this anymore.

"First let's set up some meta rules..." I hummed in thought.

"Ooh yeah, rules about rules about rules!" Max said.

I rolled my eyes at the idiot and smiled. Glad I'd included him. My pencil met paper.
