She changed a few settings on the Chronivac and pointed it at her abdomen again. She felt the babies growing, growing in her stomach, in a reversal of what she had just done, except with two instead of one. When it came time for the birth, she felt a sharp pain and was compelled to separate her legs. The two babies came out just as easily as they had come in, each followed by the cord, which soon faded away to nothingness.
Since only she and the Jills were 'aware', over the weekend everyone thought that it was perfectly normal for her to have twins. If one baby kept her busy, two kept her busy even more. A few days later, on the end of Sunday, she was more than ready to restore Jeff to normal.
The first problem was her age. She didn't want to age herself, but she knew it wouldn't make sense to be 26 and have a 16 year old son. She'd have to carefully use the 'aware' settings so that everyone thinks of her as her original age even though she's younger. They'd think she got younger overnight, but she could just say she didn't know what happened.
But the biggest problem was that the babies were listed in the Chronivac as "Jill 1" and "Jill 2." She didn't know which of the two babies was Jeff. She'd have to make them both teens and ask them. Carefully watching the two babies on the floor. she turned on the Chronivac, pointing it at both. She and the babies would stay 'aware'.
They began to grow, getting older. Soon they didn't have diapers, but had cute toddler clothes on and pacifiers in their mouths. The pacifiers disappeared as they got even older, becoming young children, then older children, then quite beautiful teen girls.
"Jeff?" she asked. "Who's Jeff?"
The one on the right yawned. The one on the left said "Me!" Quickly she altered the settings and changed Jeff to male. Now she had a daughter and a son, who looked almost identical.
The other one, Jill, yawned again and said "Mom, I was resting. What did you..." Then she gaped. "Wait a minute, I'm Jeff."
"What?" said her mother. "You were asleep?" She had known that one of the babies was asleep, of course, but it didn't register on her that that's why only one of the girls answered.
"Yeah... Mom... what's going on here? This other person may look like me, but I'm Jeff!"
"I think," said Jeff, "that we both are. I mean we could be identical except that you're a girl and you have breasts and all that. But if you're a girl you'd better call yourself 'Jill' anyway. What did you do, Mom?"
Their mother explained what happened. "I wanted to bring you back but I also wanted to have a daughter, so I made you into twins. I was planning on making it a baby daughter, but I don't think I can do that now."
Jill said "Mom, I think there's a pregnancy setting. You could make yourself pregnant and get a daughter without making me be your daughter."
"Look, Jeff, Jill, I'm sorry about that. I'll tell you what, you take your Chronivac back and you do what you want. I'll wait before I try anything else."
Jeff said "Okay,", and then he and Jill reached for the Chronivac at the same time.
"I was just--" said both of them, at once. They blinked and grinned.
"I've never had a twin sister before," said Jeff.
"I'm not your twin sister, I'm you!"
"Well, anyway, we need to do something."
"Unless you want to try being a girl for a while. You know, it's not a bad idea. Everyone will think we were always two people, Mom set that 'aware' setting only for us."
"I don't know, granted it's no worse than being a baby and it might be fun, but...."
