A lot farther!

Neo had two questions in mind.

First, how detailed could she be?

Second, what happened when she ran out of space on a page?

Worse case she could write Yang's name on another Chapter and continue with her, but she needed to be sure what would happen. So she wrote an incredibly in depth version of this song and dance for her to perform, just to see how it would work. When she finally finished, after hearing Yang go through the sexy version numerous times, she finally finished, reaching the end of the page. As she turned the page over, where usually Weiss's chapter began, she found something strange... a new page was there. It was completely blank, without even a chapter header on it. The only thing she noticed was a small number 1 appearing at the bottom of Yang's original page, and now a 2 on this one.

"So it adds a new page to the chapter when I run out..." she pondered to herself. This would make things significantly easier in the future.

But with this said, she looked up to see how Yang responded to her new details. She knew from the rules she couldn't make any actual modifications to Yang without her actually doing it. For example, she couldn't say "Yang's eyes will turn green" but she could make Yang go out and get green contacts. But she didn't know the actual depth to what she could specify in terms of what was possible. So she just sat back and watched, with Yang grabbing the feather duster to begin her performance.

"I'm a horny teapot" she began, as she started thrusting her hips

"With giant tits" she added, as she started to shimmy her torso, making her breasts shake back and forth.

"And into my pussy..." she said, as she spread her legs a bit

"Goes anything that fits" she stuffed the feather duster into her pussy

"When my tits get filled up" she grabbed her breast from beneath, squeezing them hard

"I will shout. Bend me over and milk them out!" she called out, bending forward, grabbing her nipples, and roughly tugging on them. And to Neo's surprise... a few small droplets of milk came from her nipples.

Yang then stood back up, removing the duster from her pussy, then beginning the whole show again.

Everything was exactly as Neo had written it. Including one thing which she didn't think would actually work.

'Yang's breasts will begin to produce milk'

Technically it was physically possible. And clearly it had to work within the confines of what WAS possible, so she had only made enough for a few tiny little droplets. But still, she could make a change to someone like that if she needed to, so long as it could physically happen. She wasn't sure what, if anything, she would use this information for in the future, but it was still good to know.
