The growth spurt was happening faster than Jon anticipated. He'd imagined his mother's breasts growing steadily over at least a week or two, but it hadn't been 48 hours since he made the wish and her boobs were already spectacularly big "“ soccer ball big.
There can't be more than a few hours of growth left, thought Jon as he enjoyed the view. The other parts of his wish had already kicked in, as his mom was wearing a top with a plunging neckline. He silently wished he'd ensured the growth was slower, but he couldn't fault the results.
He glanced sideways at his sister Zoe, who was staring at their mother. She was blushing so hard it showed through her ghastly white make-up. When he'd made the wish for his mom, Jon hadn't anticipated its effect on Zoe. She was female after all, and so like other women she was growing insanely jealous of her mother's massive bust. Jon almost felt sorry for Zoe, but it was so damn funny to see her this flustered.
Joan awoke the next morning to find her breasts had grown again. As she sat on the edge of her bed, her wonderful breasts sat in her lap. They were each the size of a basketball and almost as round.
She idly wondered if she should be taking this sudden growth more seriously. Of course she'd meant to make an appointment with her doctor, but she'd just been so busy with looking after the kids and the house. And, well, it didn't feel like an emergency. It was unusual, sure. Highly unusual, even. But was it dangerous? In fact, was it bad at all? Joan quite liked having enormous boobs, and her sweet husband really liked them. The sex had never been so amazing!
Later that day, Jon came across his sister's bedroom and found her door slightly ajar. Silently he peered through the whole. Zoe was standing there posing in front of her mirror, with a significant quantity of tissue paper stuffed down her top and moulded into the shape of very large breasts. Not a patch on Mom's, but still comically big. Jon laughed loudly with surprise. Her privacy violated, Zoe screamed in fury and threw a book at her door to shut it in his face.
By the afternoon it was clear to Joan that her bosom was no bigger than it had been that morning. Her miraculous growth spurt had come to an end. A small part of her was almost disappointed - but it was quickly overcome by the significantly larger part of her who was looking forward to finally being able to buy new bras! While she was shopping, Joan mused, she could look around for some new tops as well. Ones which showed off a little cleavage... if a little anything was possible with her beautiful bust. She couldn't wait to turn some heads. It made her feel young again.
"Jon-boy, where are you hiding the stone?" Karyn asked. She was leaning against his desk, drumming her fingers against it impatiently.
"Why, Karyn?" he asked as he retrieved the stone from its hiding place. "You have a wish you want to try out?"
"It's...," Karyn's face turned red, "it's your mom's boobs, Jon. I can't get them out of my head."
Suppressing a smirk, Jon queried, "But Karyn, you used to have big boobs yourself! You wanted rid of them, to go back to the way you were before. And we did that."
Jon fidgeted with the stone in his hand. He could guess where Karyn's train of though was heading and if he was right, he wasn't sure if he should stop her or not.
"I know, I know," Karyn shook her head. "It's just... seeing your mom like that, so happy and full of life since her chest... exploded... I feel like I'm missing out! I want to feel good about myself, like she does. I want to be that happy, that beautiful. And unlike other women, I don't even have to have surgery to do it! Your wishing rock can do it all for me!"
Jon looked down at the stone, wondering if he should allow Karyn to go through with this. He quickly decided...
