Jon looked out the window and saw Sarah, he pointed his index finger, glancing Karyn's way, he said, "Here goes. Give me that body"
Jon heard Karyn start to say something, and then was cut off, looking around; he realized that he was now in Sarah's body as planned! Looking down he could see her pale pink jogging clothes concealing a larger pair of breasts then he had with Zoe's body, concealed under the pink cotton fabric. Jon could feel his now long hair pulled up in a bun behind his head.
Looking out at the street, he saw his old body stopped in its tracks on the footpath, looking around in confusion. "What the hell?" he heard himself say.
"Oi, Sarah, what the hell are you doing here?" Karyn demanded, looking at Jon, "And where the hell is Jon?" glaring at him.
Jon started to reply, "Uh, Karyn "
Karyn cut him off, "Don't 'uh Karyn' me you slut! Get out of here!" she growled, practically shoving Jon through the front door before he could even open it.
"Karyn, it's me!" he called back to her, "Don't you remember me?" Jon asked.
"Of course I remember you Sarah! That's the reason I'm throwing you out of the house!", she retorted, looking past her she called out to Sarah in Jon's body, "Hey Jon, this loony was just in your house"
Sarah came storming up the front path to the house and approached the door, looking indignant and dressed in Jon's clothes.
"Sarah, what kind of game are you playing?" she said to Jon, "How did you get me out of my house and into the street. And what were you doing in my house anyway?" he accused
Jon tried to explain, but Sarah cut him off, Jon realized that a lot of people seemed to have a bad habit of doing that around here, maybe he could figure out why that was with the stone later, but now wasn't the time.
She huffed past Jon in her body, shoving him aside, "Get outta my way moron!" she growled. After a moment of muttering and watching Jon carefully, Sarah and Karyn went back inside the house and shut the door; Jon could see them inside watching him from the window.
Jon walked out to the street from the front door, clearly aware of the soft jiggling of his DD cup breasts, Jon wondered if Karyn felt the same way when she moved around.
Jon realized that Karyn was talking about Sarah's body as if he'd always had it, then Jon realized that he hadn't told Karyn that he had swapped with Sarah, so as far as Karyn knew, Jon and Sarah just randomly switched places and Jon really was Sarah, a big-boobed blonde bombshell the whole time!
Then he realized that he didn't directly tell Sarah or Karyn that he was really Jon. Of course telling Karyn would be fine, but the last thing he needed was a super-bitch like Sarah learning about his wishing rock.
Holy Shit!, Jon thought in shock, She thinks she's me, which means she thinks she owns the wishing rock too!
Then he calmed himself, remembering his little "perception wish" that he put on the rock. Sarah wasn't actually Jon and wouldn't be aware of the rock in his drawer, even though she technically knew about it now. Come to think of it, neither would Karyn.
After a moment of Sarah and Karyn muttering and watching carefully Jon turned around and resumed Sarah's jogging in her body. He figured he should wait until Sarah left before he tried to switch back, he didn't want to do it while she was at his home, hilarity may ensue.
Jon jogged down the street, surprised at how easy it was compared to when he jogs himself, Sarah kept herself in good shape, very good shape and Jon was beginning to enjoy the feel of his new breasts as he continued. Sarah's body was getting aroused by the constant jiggling.
Jon wasn't sure where to go from here, "Jon" and Karyn may probably spend half the day tearing up the house to find the wishing rock, Jon could always wait until evening before he went back. Of course he could easily "mentally" track the rock location if it got misplaced too, so he didn't have to worry about that. But it was still disconcerting being considered a stranger in your own home, even if no one knew it was yours.
Then it occurred to Jon, Sarah has a home too, and technically a boyfriend, he could hang out with Biff Meadows and dig up some dirt while he was "borrowing" Sarah's body and use it against him later.
Or he could just go to the mall or something.
