"Damn it Zoe! I'm trying to get changed in here. Can't I get a little privacy?" Jon yelled at his sister.
"Whatever pervert. Mom wanted me to tell you that she ordered pizza for dinner and it should be here in half-an-hour." Zoe said while turning to leave.
"Okay, thanks. Now get lost."
Zoe shut his door with a little more force than was absolutely necessary but not enough to make there mom yell at her for slamming it.
As soon as the door was closed Jon rushed over and locked it. His privacy assured he went straight to his computer and check the internet. Zoe's comment about having her dick out was worrying him.
When he checked out some of his favorite porn sites (because that was the fastest way he could think of to see if everyone's genitals had changed) he saw normal looking men and women with the genitals he would expect to see on each of them. So it looked like his wish hadn't affected everyone which he was grateful for. Even if they wouldn't know any better, he would still feel bad if he had changed everyone's genitals against their will.
His next though was that perhaps he had changed everyone in his family. He picked up the stone and said "I wish I knew what kind of genitals the people in my family had." He instantly regretted that wish when images of each of his family members genitals flashed through his head.
"Okay. I did not need to see that." Jon said aloud before setting the stone down. The images that had flashed through his head had confirmed that everybody else in his family had been unaffected by his wish. At least physically. Zoe hadn't thought it was strange that he had a vagina instead of a penis.
Finally tired of trying to guess what Zoe had meant Jon decided to go straight to the answer. He picked up the stone again and said "I wish I knew what the results of my last wish were." Once again images of his family members' genitals flashed through his head.
"Fuck. That wasn't what I meant. I meant the wish about MY genitals." Of course since that wasn't phrased as a wish nothing happened. "Damn it you stupid stone." Jon said. "I wish I knew what the results of my wish to change my genitals were."
This time his wish was granted as he'd intended and the answer sudden popped into his head.
