According to the stone, Jon had recieved a visit from the Boob Fairy. It turned out that the Boob Fairy wasn't completely infallable. Just like the Boob Fairy could accidentally miss some girls, resulting in them never developing breasts, or hit some girls more than once, like with Karyn or Athena, she sometimes hit boys with her Bust Dust. And Jon was one of them.
Jon was horrified. How was he supposed to function like this? His boobs were even bigger than Karyn's. He put on his biggest shirt, which bulged outward from his massive tits. He left his room with his arms crossed over his chest and began looking for his mother. As embaressed as he was, getting the humiliation over with as soon as possible was preferable to the alternatives.
Unfortunately, he ran into Zoe before he ran into his mother. "What's wrong with you?" she asked. Noticing the unnatural bulges beneath his shirt, she said, "You have boobs now, don't you?"
"I got a visit by the Boob Fairy last night," said Jon.
"Geeze," said Zoe. "How much bust dust did she get on you? Athena got dd's when the Boob Fairy visited her the second time and yours are even bigger. I don't think they even make bras in your size." Zoe walked away, laughing.
Jon's mother heard what was going on and came out of the kitchen. "Oh, no," she gasped. "The Boob Fairy got to you, didn't she?"
"Yes," was all Jon could reply.
"Its a good thing its a weekend," continued Jon's mom. "We can get to the store and get you some boy bras. I hope they have some your size, otherwise you'll have to go braless untill we can get some custom made. We'll also have to get you some new clothes too, while we're at it." Jon and his mom got into the car and drove off to the clothing store.
