The glow faded, and Jon saw Karyn, looking the same as usual. But it was himself—no, _her_self—that had changed dramatically.
In fact, Jon looked entirely like a girl. Shorter, longer hair, boobs, wearing a surprisingly feminine outfit, and—wait, why did he still have a bulge between his pants?
"Could you imagine?" Karyn asked...her.
"What?"
"Earth to Jonica! You know, we were just talking about what if boys and girls grew up into different things?"
It took her a minute to understand. "Oh, oh yeah."
"I mean, it'd be weird if boys weren't just a kind of girl, you know what I mean? Glad we didn't decide to visit that reality."
Jonica, apparently, struggled to process what her friend was saying. So boys become women like girls do? Karyn walked off toward the bathroom, giving her a chance to wish and figure out what was up.
Both boys and girls go through the same puberty. Boys have everything girls do except a vagina. Yes, a boy ovulates too here. Boys become women, just like girls do.
Jonica looked around at her room. There wasn't a single face there that looked male, including her own. Having female puberty really did erase most of the physical differences between boys and girls.
A boy would be an alien here, she thought.
