As they sat, Karyn's gaze drifting down to Jon's chest every few seconds only for her to realise it and look away again, they were both thinking about Karyn's request to test drive their new equipment, when a thought occured to Karyn: How did people know what sex a baby is? What else is different about the world now?
She reached into her pocket and pulled out the stone.
"Hey, what are you gonna..." Jon started to say when Karyn shushed him.
"I wanna know a bit more about what else we changed, don't worry I'm not going to mess with you."
She paused for a moment to consider her wish.
"I wish Jon and I knew the important differences between the world as it is now and the way it was before Jon's last wish."
Again knowledge flooded into their heads. Boys are born with penises and girls with vaginas, and they stay in the same form until a certain point in puberty when the genital cycle starts. Social attutudes towards gay people has relaxed much more quickly, because they can have children the taboo was never as strong in this version of reality, though it still existed and world history is nearly identical. It can be difficult for same sex couples to have children since their cycles will not naturally sync up so that they have the opposite sets the way straight couples will.
The information shoving itself into their conciousness narrowed to differences that affected them more directly: Ever since his chest developed rapidly over a summer he had been getting teased about the fact that his boobs would be large even on a woman. Jon and Karyns cycles synced up every time they were single, which was most of the time since they had started, they both knew it and hadn't brought it up. There are men's panties and women's briefs now, and all pants are cut with room for a penis in the front.
Jon had to buy his bras in the women's section of the store since they didn't stock his size in the mens section, he still bought very plain ones, but it bothered him.
Birth control that worked for the female part of a cycle exists, though neither of them were on it as it locks you into the female part for considerably longer and it requires timing and adjusting to whoever you're syncronised with as the change to the two cycles will affect each other.
Karyn had one peice of data just for her: prior to her accidental wish for big boobs of her own she had been mildly annoyed that Jon's were bigger than hers.
"Uhg!" Karyn said, "I had forgotten how uncomfortable that is since the last time!"
"Yeah..." Jon said.
Jon glanced down at her chest then at her crotch, she was sitting with her legs very wide apart, he assumed because it made her less aware of the strange new sensations of her male parts, and he could see the bulge of that part in her pants and again found himself wondering: How big is it?
"Umm... we should probably actually talk about what you wanted at the park, and well are we going to stay just friends, I mean our cycles are synced..." Jon trailed off, feeling awkward talking to Karyn about this sort of stuff.
"Well, what do you want? I'm not certain now, but I know which way I'm leaning." Karyn said, nervously. She had gone back and forth on weather she really wanted to be Jon's girlfriend ever since she had impulsively asked to "try out" her penis with him in the park, but she had kept coming back to yes, she did want to be more than friends, and if so she wanted to get into his panties tonight.
Jon thought about it some more, he was guessing Karyn wanted the relationship change. He felt unsure, could he risk their current friendship? Would he loose that anyway if he said no? He looked her up and down again, eyes settling back on her face. He did notice that her gaze had slipped back to his chest.
Jon let out a breath he hadn't noticed he'd been holding and said:
