Jack awoke to see a strange woman standing in the doorway, but one with a familiar look to her face.
The lightbulb went off. "Oh, you found the Chronivac."
"You like?" Sandra did a graceful pirouette to show off her new body.
"I like. But first" Jack sat up in bed, smiled, and beckoned Sandra closer. "I think I need to see the whole package." He pulled at the knot fastening Sandra's bikini panties, and the underwear fell to the floor. With a smile, Sandra brought her new body into Jack's bed.

Post-coitally, the lovers lay with arms and legs entangled, and faces close enough for kissing or conversation.
Sandra began, hesitantly. "You used this on yourself, didn't you? To enhance your manliness? I mean, four times in one morning!"
Jack gave a snort of laughter. "To enhance my manliness? Well, I guess that's one way to put it."
Sandra was even more curious now. "So what did you do?"
Jack kissed her. "You want to hear the whole story? I should warn you, parts of it are a little weird."
"No." Sandra answered. "Tell me. I want to know all about you."
"OK." Jack answered. "You asked for it."
