"How about a makeover?" Cathy suggested. "But, not an ordinary make over."
"What do you mean?" Amy asked.
"Well, Judy said that she made her boobs bigger besides just making herself older. We could do something like that too."
"Yeah," Judy said. "That'd be great. Just tell me what you want to change."
"Ooh!" Amy said and raised her hand as if she were answering a question in class. "Can I have bigger boobs too? Please, can I?"
"How big?"
"Like BIG, bigger than yours even."
"Hang on," Cathy cut in. "It was my idea. Shouldn't I go first?"
"Please, Cat," Amy said, clasping her hands together as if praying to her friend. "I always wanted to have a big pair of boobs to play with."
Cathy sighed. "Oh, alright. I can wait."
"You want them big?" Judy asked in confirmation.
"Huge!" Amy replied enthusiastically.
"Control Amy's boob size," Judy said and blew a large FOOOOOFF into the balloon.
Amy's pink one piece was stretched to the limit on the top as boob flesh was clearly visible swelling out from the sides by her arms and over the top in a sort of split muffin top of cleavage. "Whoa," said Amy as she awkwardly tried to peel the painfully tight bathing suit down from her shoulders over her massive tits. Eventually, she freed the two enormous globes, which bounced out like a pair of fleshy basketballs on her chest. "Awesome," she said as her hands hefted and fondled her soft new assets. "They feel amazing," she said shutting her eyes and smiling.
Judy smirked and blew into the balloon again, FOOOOOOOOFFF.
Amy gasped as the fleshy weight in her hands dramatically increased. She stumbled forward and nearly fell over. "Whoa," she cried as she recovered her balance. She had to lean back a bit to support the weight of the giant globes of flesh hanging off of her. Each breast was twice the size they had been a moment ago, and her nipples jutted out as thick as her thumbs.
"Judy!" Amy whined. "That's too much." She groaned. "Oh, my back! I'm going to tip over. Help!"
Judy chuckled and then waited a few seconds as Amy fumbled with her arms to better support her absurd boobs, which spilled out uncontrollably over her arms however she shifted them. Once Judy was sure of her dominance, she let the balloon deflate again, just enough to bring Amy back to the size she had been before the second blow. She was still enormous but relatively normal now.
"Release," Judy said.
Amy sighed and carefully let her boobs go. They hung down nearly to her belly button, and they were certainly the biggest breasts that Jim had ever seen outside of internet porn, each one looking larger than her own head. "That was not cool," she said, with a touch of anger.
"What?" Judy asked, feigning innocence. "You wanted them big."
Amy's eyes shot daggers at Judy. "You knew what I meant."
"Hey, girls, it's cool," said Cathy, playing peacemaker. The other two looked at her. "I mean, you got what you wanted, right, Amy? Judy was just having a bit of fun. We're good, right?"
Amy looked down at her boobs again. "They do look pretty sweet now," she admitted reluctantly. She looked back at Judy. "Thanks, I guess."
Judy spread her arms for a hug, and the two of them awkwardly tried to wrap their arms around each other. Unfortunately, there was too much squished tit flesh between them to do more than just pat each other on the shoulders. "Just be more careful next time," Amy said. "That thing can be dangerous."
Judy nodded. "I promise I'll be careful," she said in her sincere-sounding "reasonable" voice. Jim had to fight not to groan.
"Great," Cathy said. "I hate it when we argue."
"What now?" asked Amy.
"My turn!" said Cathy.
