The dictaphone

Vanessa entered her bedroom with a large smile. This day at school had been amazing! Thanks to her new breasts, she thought, hefting them with pride.

Whatever caused her growth, the sudden increase of her already ample bust size made the girls look at her in awe, and the boys drool. Of course, the word out was that she had implants, but Vanessa quickly showed with ample bounce that it wasn't the case. And that you don't really have perfect surgery overnight. Padded bra or a weird allergy, all the rumors were on, but Vanessa didn't care as long as she was the center of attention and had even more of a killer cleavage than she already had. For some reason, a few girls seemed especially enthusiast about her growth. Lucy, Liz, Amber, and a few other girls... they couldn't stop complimenting Vanessa about it. Like they were obsessed about her enhancement. Weird. Still, they compared her with other girls in favorable ways, even with a girl called Christy.

Christy. Vanessa had heard of a very tall girl sporting G cups being the queen bee of another school... well, now, she had a rival! Vanessa didn't know her, but she couldn't stand the idea of being second to someone.

Vanessa checked the clock on her wall, and noticed it was already quite late. It was the end of the evening, the night was already there, and Vanessa needed good nights of sleep if she wanted to keep her good looks. She disrobed, putted on her pajamas, but not before she checked once again her new curves... and went to bed. She heard her mother saying through the door "Good night, Vanessa! And don't worry, we'll buy G cups bras for you this weekend." She heard Wendy angrily mumbling from her bedroom, jealous of her sister's growth while she was still waiting for her own, and soon after, fell asleep.

So she couldn't hear when the bedroom window briefly opened moments later, and invisible faeries flew above her body.

She barely felt something when Eden the first, the boob faeries queen, landed on her right breast with a smile.

"Okay girls, let's grow these tits even bigger!" Eden said to the flying formation of faeries with heavy bags above her.
"My queen, this powder was supposed to go to other girls as..." Chance started.
"Royal decree, my dear chancellor. What is the point of having a queen if you never have decisions?" Eden exclaimed "Go on, girls!"

The group of twenty boob faeries, packing each enough dust to make any growing girl quite busty all dropped their content at once, a cascade of shiny powder falling on Vanessa's tits, resulting again in her nipples hardening, a small moan from the sleeping giantess, then the start of the expansion of her chest right under Eden's feet. Months of growth for several regular girls were happening at once to Vanessa.

"Yes... grow, grow bigger! Come on, bigger!"

G cups quickly became a thing of the past, as Vanessa's chest grew bigger and bigger, Eden pushed higher and higher, as the G cups under her feet became H cups, then reached the limits of this size, leaving Vanessa with an even more impressive chest.

"She's huge!" said a fairy, before she giggled "I love it!"
"That's the spirit!" Eden said, flying above Vanessa to get a good look at her work. Vanessa's breasts were gently spilling out of her top because of their increased size, and the fact her top was still one made for a girl two cup sizes smaller.

"That's it. Let's go home, girls... we're done for tonight!"

Vanessa yawned in her bed, grunting at the alarm clock ringing. She turned to hit it with her fist and stop its annoying sound, when she felt a heavy weight on her chest, her breasts, a lot heavier than usual, moving against each other. "Ah, that's right, I'm a G cup now..." Vanessa whispered to herself, smiling as she looked down...

... and met things a lot bigger than G cups!

"The HELL?!" she exclaimed in shock, before she smiled in confidence : she grew AGAIN?! This had to be another whole cup size just overnight! How could she grow two cup sizes in just two days? Vanessa then smirked : it meant... she was bigger than the Christy girl she heard about, not just equal. The idea of having bigger breasts than her rival made her smile wider, and Vanessa started her day with a smile.

As she crossed Wendy in the house, she trusted her chest, and Wendy's eyes almost popped out.

"Are.. are these BIGGER?!" she said, her tone full of distress.
"Oh, I think they are... obviously, the boob fairy loves me!" joked Vanessa "I must tell mom to cancel this G cup bras order... these won't fit in tiny things like these!"

She laughed, before she joined her family for the breakfast, and said she was feeling fine, no, better than fine when her parents asked her if she was feeling sick or something. Vanessa then headed to school, breasts obviously too big in too small clothes, ready to feel the envy and lust growing even bigger than the day before...

... just like herself.
