I grabbed the die and looked around the shop. If I was going to keep growing like I wanted, I was going to need somthing to roll the die in. The last thing I wanted was to be unable to roll the die more just because I was pinned to the ground by my massive breasts. Luckily, I was able to find an old cardboard box that was a small enough size but sturdy enough for me to make more rolls without losing the die. Now that, that was taken care of, it was time to grow. Best to start slow, really savor this.
"I wish my breasts were two cup sizes bigger," I said and rolled. Two was a safe number. 4 if I roll a 20, and I only lose 2 sizes if I roll a 1. I smiled as my breats began to grow, but somthing wasn't right. They were bigger sure, but they didn't grow the full two sizes. "Hmm," I mussed as I lifted a breast in each hand. Looking at the die I saw what I rolled. 7. Thinking about my previous rolls I'm pretty sure I understood the rules now. 1 is the opposite. 2-9 was half a wish. 11-19 was the exact wish. 20 was double. The only thing left was if there was a limit to how many rolls one could make. "Well, when you're on a roll," I said with a smirk, "I wish my boobs were twice as big." It seemed like a fun bet. Double the size if I rolled high, 1.5 times if I rolled low, sure I'd lose half my size if I rolled a 1, but if I rolled a 20... I shivered at the thought. I rolled the die and anxiously waited for it to land.
