Ok, so maybe it was a little bit of a tease to test the wish on Zoe like that and give her a fright, but no harm was done. Jon was ready to test the last part of his wish on Zoe and then help Karyn get HER body back to normal. Jon had gone back into his room for a bit and fiddled around, waiting for Zoe to finish her shower.
He heard the running water turn off and the bathroom door open, so obviously she was headed back to her room to get changed. Jon wondered if she was going out at all until he heard a voice from down the hall.
"Oi Jon! I'm going out for a bit with Ath and Zel, make sure you tell mum!", she called out her door, partially muffled by the shirt she was trying to slip on.
After a few more minutes, Jon heard her door swing open again, "Alright, I'm off!" she called out.
Jon dashed out the hall and watched her head down the stairs to the front door, he jabbed out his index finger and called out, "give me that body below the neck!"
It was a bit more complicated then just swapping breasts or hair, but it was the last part of the wish to test. Testing if the wish would accept more specific instructions and if no-one would recognize it. Jon felt a sudden flurry, in a split second everything changed. He looked down and saw the familiar tightness of his T-shirt on his chest. Although this time he was feeling strange all over, the wish had worked.
Jon headed back to the bathroom and took a look in the full sized mirror. Looking back at him was his same old face, on his same old head with his same old haircut, however, everything below his neck was not his anymore. The skin changed to a finer grade, softer and smoother to the touch, mostly hairless too except for very fine fuzz.
His entire figure from the neck down was now his sisters. Her C cup breasts stood out proudly through his t-shirt which now didn't fit him properly, loose over his shoulders and tight in the chest rather then the other way around. Further down his shorts were strange too, they were a bit loser on Jon then he was used to and was hanging lower, but at the same time was very tight around the butt. Jon couldn't help but notice the strange feeling of a void between his legs at the same time. He tentatively touched his crotch to confirm that his one man ship was indeed gone from its port and replaced with his sister's vagina.
Jon could see his sister's smooth legs and petite feet finishing off his new body. Comparing himself to the bathroom fixtures, he figures he'd lost a good foot of height, now somewhere around 5'2 rather then the 6'1 he was before the swap. His head looked a little strange sitting oddly on his new body like it did, slightly out of proportion.
Jon heard the front door slam shut behind him, he raced out of the bathroom all the time feeling the movements of his new strange body to the front bay window..
Jon was stunned and amused at the same time, Zoe apparently had no idea that she had suddenly become male from the neck down, Jon's former body had increased Zoe's height just like it decreased Jon's, but at the same time it was hilarious to see her wearing obviously female clothing on a male body.
He could see what was now her penis was bulging through the front of her tights and skirt and at the same time the hairs on her masculine legs poking through the tights. Further up, her bra and shirt that would normally be form fitting were now loose over her chest. On his fingernails he could see black fingernail polish now covering his longer fingernails.
It was a sight to see for sure and to make things more amusing, no one even noticed that the two of them were mix and matched, Zoe waved a greeting to Mr Black next door as he went out to collect his morning papers, he returned the greeting and even commented on how radiant Zoe was looking. Pure hilarity.
Jon was suddenly snapped back to reality by the sort of pulling feeling in his chest, he couldn't get over the slight soreness that his new breasts were affording him, and from the looks of Zoe, she was uncomfortable with the panties that were now constricting her new penis.
Looking down at himself, he really was a woman now, completely from neck to toe. Jon put a hand to his breast and another worked its way down his underpants. He started to feel himself up, reveling in the feeling before he stopped.
Oh god, this is my sister, It's like doing her myself! This is sick! Jon thought, stopping himself before he got any worse.
He'd already gotten his new pussy wet and his nipples were poking through his T-shirt. But at the same time, it was feeling pretty intense. Jon wondered if he'd be able to stop himself if this body was anyone else's rather then his sisters.
