Nia could feel a warmth going through her body after she made her wish. Looking down, she saw that her wish actually had come true: her boobs had started to grow.
She watched as the front of her business suit's blazer filled out, her breasts entering the D cup range. She'd always liked her looks, but did feel from time to time that she could benefit from having a larger bust. And now she was getting just that.
As her breasts swelled into F cups, she turned to look at the others. They weren't looking in her direction, so they couldn't see her growth.
It was when her breasts entered the I cup range that Nia started to think something was wrong. Her blazer started to feel rather tight, her breasts were starting to get heavy, and said weight was starting to put a strain on her back. And worse, she was still growing. She turned to Lou, who was staring at her.
"Um, Lou?" Nia asked. "When is this growth supposed to stop?"
"I dunno." Lou replied apathetically. "You just asked for them to grow. You didn't specify a size."
"I only said a SMIDGE bigger!" Nia yelled as her boobs swelled into P cups. "I feel like I have sandbags attached to me!"
"You know, I'm friggin' sick of humans." Lou said. "400 years of granting, and not once have I had a human who wished for something meaningful. I can end hunger, stop wars, and even bring world peace! But no, it always selfish shit like 'I want a million dollars', 'I wanna work from home', 'I want bigger boobs'.

Now sitting on the ground, Nia watched as her bust finally started to slow it's growth and eventually stopped. Her breasts now seemed to be the size of prize-winning pumpkins, filling her entire lap, and weighed about three times as much.
"Um, can I wish for them smaller? Or to weigh less?" Nia asked nervously.
"Sorry, nope." Lou replied. "Five wishes per bottle opening. And your friends just used up the other 4. You want another wish, you gotta find me again. See ya!" With that, Lou vanished in a puff of pink smoke, the bottle vanishing too.
All at once, people started moving again, and Nia discovered that her blazer had been repaired and made to fit her now immense bust. People were obviously staring at her, including her friends.
After a few seconds, her friends helped Nia up and started to...
