Expanding ass

    by: Expansion K Author IconMail Icon
Just as Zack responded to Cody's question, he felt his tattered shorts start to get tighter and tighter. Jason and Cody watched as Zack's rear end swelled and grew, his cheeks rounding out into a bubble butt before they continued to expand. Zack reached behind, just to feel his ass cheeks and confirm that they were indeed growing.

Zack's shorts ripped in the back, and Cody had to stifle some laughter as Zack smiled and said, "Man, it really does work like a charm!" and Cody chuckled as he said, "Of all the stuff in the book, this is what you pick?" and Zack said, "Yeah, what's wrong with it, balloon boy?" and Cody said, "I'm sorry for laughing Zack, this is just the last thing I was expecting from you!" and Zack blushed a bit, saying, "What? I've always wished I wasn't so flat back there!" and Cody said, "I guess there's still a lot we don't know about each other." and Zack said, "Well, now's our chance to go all out!"

Jason was amazed by this. He didn't expect the twins to even want to try using the book, let alone take a liking to it like this. He watched, fascinated as Cody took the book back, saying, "Wait, I wanna see something!" and he flipped the pages back to the beginning, staring at them intently before putting the book back in Zack's hands.

This book was made for all sorts of expansions, right? It's only natural that they designed spells to be able to read the book hands free, just in case a user can't move or use their arms or something!" and Zack said, "Wait, I wanna learn those words! Say them again!" and Cody said, "Sure!" and he said the summoning incantation aloud for Zack. Zack then repeated the incantation, and the book obediently floated over in front of his face like it had done with Cody. It was open to the page that Cody was reading, so Zack was able to read the page turning words, too.

Cody then said, "Hey Jason, you wanna try another spell? We both got our own turns." and Zack said, "Yeah, it's only fair, since you were the one who found the book!" and Cody said, "Unless you don't want to." and Zack said, "Yeah, you can just watch us if you'd rather do that!" and soon, Jason wanted...
