Jon called Karyn over, it was a simple enough matter, she'd been up all night because of her new assets. Ironically since no-one else had heard the wish, she spent most of the morning arguing with her mother of why she needed size DD bras when she used to have size B ones, even though according to her mother, she'd been a size DD since she was 16, a good 2 years now. Karyn was desperate to get her problem fixed, or at least a bra that fits.
She got to the door and rang it, Jon got up from the couch and answered the door, he had purposely gone into Zoe's room while she was out and gotten some tighter clothes to put on to show off his new assets to Karyn. Hopefully to see if she notices something weird.
Karyn gave Jon a look over, and she regarded him with a curious glance, "Something you wanna tell me Jon-boy?" she asked.
Jon replied, "Why, whatever do you mean?" stifling a giggle.
She figured it out already, clever girl, he thought to himself.
"Well, for starters, why are you wearing Zoe's clothes?" Karyn asked, Jon's heart sank, she hadn't figure it out.
"Don't you notice anything else odd about me Karyn?" Jon asked, as he let her into the house. He shut the door and led Karyn into the living room.
"Not really, same old you. Although I am jealous you have a bra that fits, my mum wont spring for anymore until next winter", Karyn grumbled, "Apparently she thinks it's not important since I always asked for B's before and the sudden desire for a form fitting bra will not change her mind", swatting a strand of hair from her face, "Ugh, and even this hair is annoying the hell out of me. I want my old body back!"
Jon smiled, "Well, I think I have a solution for you, Karyn"
"Does it have anything to do with why you're cross-dressing?" Karyn replied.
Jon was amused, "What do you mean? I'm a girl aren't I? Shouldn't I be wearing girl's clothes?" he asked innocently.
Karyn was uncomfortable, "Well, yea, but you never seemed interested in that. I mean apart from the essentials, bras and panties, you always wore boys clothing over the top. I suppose it didn't matter to you parents that much since Zoe was practically the exact opposite, wearing girls clothing over boy's undergarments", she answered, "Don't you remember? It's how you got your nickname 'Jon-boy' "
Jon laughed again, "Karyn, I've got Zoe's body from the neck down", he exclaimed to her.
She looked him over, and it was almost like a light went off in her head, "Oh my God, you do!" she replied, stunned, "I can't believe I didn't realize it! It's like I know two pasts, you've always been a girl, but you've also always been a boy!" she said, almost ready to pass out, "What did you do to yourself? Was it the rock?"
"Sort of", Jon replied, explaining exactly what he'd done. Karyn listened through all of it, from Jon thinking about how to fix her all the way to Karyn's dad thinking nothing of a 7/8ths boy wearing gothic girl's clothes.
Karyn took it all in, "Well, I have to admit, I don't think I'd have personally tried to switch sexes, but hey, it's not my rock", she said, sitting back in the chair.
"well it was that or the family dog", Jon replied, "And I wanted to get you fixed so much, it was kind of my fault you are how you are now", he said.
"That's so sweet Jon-Boy", Karyn replied, "But don't you think it's time you give your sister her body back?" she asked.
Jon nodded; he stood up and said, "You can have it back", to no one in particular.
Karyn watched as nothing seemed to happen, "You sure it's working Jon-boy?" she asked.
"Yup", Jon replied, "You can have it back", he said again.
Karyn didn't notice anything again, " Jon?" she asked, slightly impatient, "Where is it? Or do you like your sister's body that much?"
"You can have it back", Jon said for a final time, this time the change was obvious. Karyn watched as in a split second, Jon went from being 5'2 back to his 6'1 self, his body practically exploded out of Zoe's clothes, stretching them all the to the limit.
"Ouch", was all that Jon could say, looking at himself, "Maybe I should have gotten out of Zoe's clothes first"
"Looks like it", Karyn replied, "Here, let me help you"
With a few tugs and pulls and a very sore gut, Jon managed with Karyn's help to remove Zoe's previously form fitting clothes, standing in his living room in only his old underwear, with Karyn watching. Jon noticed that Karyn's eyes kept drifting down below his belt to his underpants.
Jon blushed, "Maybe I should get changed?" he suggested.
"Good idea", Karyn replied.
Jon went to his room to get changed.
