Do some tests, see how far it goes

Danny looked at the book and wondered what it is he could do with it. Technically, he could do anything, really. But how far can he take it, and would he really want to go far with it? He thought he should first do some tests with it. Give it a test run, and see what it's limits might be.

Danny pondered for a moment what it is he should do first. After a moment, he grabbed his drink and took a sip, only to find it frozen. After the initial shock, he realizes he froze it with his ice powers. He sighed and put it back down. He really needs to get a hold on his ghost powers... After a moment, a thought popped into his head.

With the book, he could have full control over his powers. He could be able to use them and not have any accidents. Hell, he could gain even MORE powers if he desired it! He grabbed his pencil and wrote down his new rule.

New Rule: Danny Fenton, AKA Danny Phantom, has full control over his ghost powers, and using them does not tier him out.

Once done, Danny didn't feel all that different. To test if it worked, he grabbed his frozen drink and see if he could unfreeze it. With almost not effort, the frozen beverage returned to it's liquid state. Danny smiled and laughed a bit, taking his long awaited sip.

Danny is happy with how this turned out.

"If this book can effect my powers, what else could it do for me?" He asked. It didn't take long for his young mind to reach some more... perverted, fantasies. If it could improve his powers, why not improve his body? And if he didn't like it, he could change it, right?

New rule: Danny Fenton has a 12 inch penis.

Danny had to hold back laughing and smiling too much as he wrote this rule. And soon enough, he felt something. Looking down, he could feel his penis growing larger and he saw it going down his pants leg. Once it reached it desired length, Danny let go of the breath he didn't notice he was holding. That... felt more arousing than he expected.

But now that it was done, he could confirm that it indeed could change his body, and for the better. Yeah, he's definitely not changing this back.

With that done, he wondered what else he could test out. He thought for a bit, but nothing was coming to mind. He looked around to see if anything could give him an idea. And then, he saw it. Well, her. Paulina, the most popular girl in school. Beside her was her friend, Star.

Danny look the two girls up and down. They had some killer body and only enhanced their beauty greatly. They were slim and with curves, with great ass and nice busts. But... they could be better. And without a second thought, Danny grabbed his pencil and grinned as he wrote down in it once more.

Old Rule: Paulina Sanchez has G cup breasts

Old Rule: Star has F cup breasts.

Once Danny was done, he looked over to the two girls to see if it worked. And sure enough, from where he was sitting, their breasts were getting bigger and bigger. But they weren't reacting to it at all. Probably due to the books reality changing effects. After a while of watching the two girls getting bustier, they reached their full magnificent new sizes.

After seeing this, He really couldn't help himself. His dick was hard, and he didn't have enough blood in his brain.

What will he do now?
