Gabe stood there, staring at his friend's crotch.
"I see your pussy's already ready for me, baby!" he said.
What? Gabe was Jon's friend, but what was going on?
Then Jon figured it out. The stone changes reality. In the new reality where Jon had a vagina, Gabe wasn't just Jon's friend, he was Jon's boyfriend. Jon knew that this was a great chance to try out his vagina, but he wasn't really attracted to men. But now that he had a vagina, he realized that with it came certain sensations. He was excited from having rubbed himself over and over, and he realized that with his female sexual excitement came a sudden desire to be penetrated.
Not that he couldn't refuse--refusing would just make him feel a little sexually frustrated. But he didn't want to be frustrated.
Jon decided to do it. First, he'd need to raise the time limit. He had already used up much of the ten minutes and having it wear off at the wrong time could be very bad. Jon picked up the rock and said "I wish that after the ten minutes is up, I would continue having a vagina until next Monday, and that Gabe doesn't notice this wish."
"Jon?" said Gabe. "Jon-boy? We were going to...."
Jon smiled at Gabe and Gabe kissed him while starting to fondle his new female parts....
