"Of course," replied Steve. Inwardly he was pleased. His plan seemed to be working--Claire made a few changes to Mark, but then Steve made some more. "But why don't we have some fun with the Chronivac once we get back?"
"Fun?" asked Mark.
"Sure, Mark! Isn't there, oh, some change you might want to make?"
"Change... Hmm, I've thought of something, but it'll be a surprise. Okay?"
"Sure," said Steve. "Anyway, I'll be right over. See you then. Bye, love!"
"Bye, Steve. I can't wait for tonight!"
When Steve arrived it was just as he had planned--everyone accepted him as a friend; there were no complaints of him having once been a bully. Since they had gone to the movie together, there wasn't much of a chance for more than a couple of kisses in the dark, but afterwards, instead of going to the bars, Steve and Mark went directly to Mark's apartment. Since they were now adults, Mark wasn't living with his parents. He did seem to be still living with his brother Tony, but Tony was still out at the bars.
"Do you have the Chronivac?" asked Steve.
"Sure I do. Jeff let me borrow it. Hold on...."
Mark went into another room, as Steve followed. Mark plugged the device in and began to run the software, selecting various menu items and pointing it at himself. Then he said "It's finished."
"What's finished?" asked Steve. "I don't see anything different." He knew, of course, that Mark's pussy was waiting for him.
"Come on, let me show you! You know, I may be a guy, but I always wanted to be be able to bear children. It may sound strange, but it's true. So I used the Chronivac to make it possible. I love you, Steve... would you like to be the father of my child?"
"O-- of course. Because it's you..."
Mark and Steve went into the bedroom. Although they had been younger, changing into adults gave them certain abilities to do things that adults did, so they found sex familiar... until Mark revealed his new vagina.
"I changed my pussy," explained Mark. "I had to in order to make it possible. I so want to do it..."
Steve was a little annoyed that Mark hadn't become a hermaphrodite--he was a guy with only a vagina and no penis. But then, he had only programmed in a desire to bear children, the method Mark would choose was up to him.
An hour later and after lots of sex with Mark taking the female role, penetrated by Steve, they finally decided they were tired. Mark explained, however, "It's not over."
"It isn't?" said Steve.
"No...." Mark went to the other room and fiddled with the Chronivac again. In the next minute, Steve watched Mark's stomach bulge out. With another adjustment, Mark had a baby crawling in front of him, without having to suffer the pain of giving birth. Then the baby began to get older, growing, and no longer crawling. Mark added a few final adjustments to keep everyone aware of reality, yet make sure that the child he gave birth to could talk and generally act like someone his age rather than as just a big baby.
Soon in front of them both was a naked 18 year old, who looked at the two, a little confused. "Mom? Dad? You are my mom and dad, right?"
"That's right," said Mark. "We had sex just a few minutes ago, but with the Chronivac I'm now a parent, just like I wanted to be! Even though I just changed enough of me to be able to have you."
"Oh, wow," replied the 18 year old.
"He's your mom," said Steve, "and I'm your dad. Even though you're now just a little younger than us. Nobody remembers you since you've just been born, but maybe I can introduce you to my friends when they visit? At least to Tony--he's your uncle."
