"Jon, there you are!" came Karyn's voice from behind. "Where you been hidin' yourself?"
It didn't seem to Jon that he was hiding himself at all, but he nevertheless answered Karyn's question.
"Gym class," Jon replied. After all, there was little point explaining how the current situation had come about. It would seem to Karyn and everyone else that things had always been as they now were.
Karyn was dressed as Jon remembered her from earlier in the day, and so were all the girls Jon noticed. None of them, including Karyn, seemed surprised or bothered at all that Jon and all the other boys and men were naked. Until, that is, Joseph joined the two of them. Karyn immediately reached for his cock and began fondling it.
"Oh good, you saved some for me," Karyn remarked as Joseph's cock grew erect.
"Why are you doing that?" Jon asked with some amazement.
"Huh! Just like a boy!" Karyn exclaimed. "You guys get all the sex you want from each other and us girls have to beg for leftovers."
"Oh, sorry, I didn't mean to be offensive," Jon apologized. "But, uh, don't girls sometimes have sex with each other?"
"Eew!" Karyn spat. "How can you even suggest that? Girls' bodies are ugly. Everybody knows that. You guys are the beautiful sex. That's why you attract each other as well as girls. Oooh! Oooh! Hang on!"
Jon watched unbelieving as Karyn dropped to her knees, finished Joseph off, and let his cum dribble down her blouse. "Oh, I'm gonna make that Sarah McMillan so jealous!" she squealed.
"You know, Jon, some people think you and Jeff are the wave of the future," Karen explained from within her drenched blouse. "If enough men could reproduce, nature wouldn't need us ugly stunted girls anymore!" Then she hugged him and remarked, "I wish I could be a guy with a pussy the way you and Jeff are."
