Tube Twins

... agoraphobia and extreme mental shock. Our whole world view had been turned on its head! The computer must have sensed our distress and drugged us, because I woke up much calmer a short time later. Girl was still asleep. It was reassuring to feel her face next to mine, her left leg between mine, and her body in my arms.

When Girl woke, I asked, “We want to see the rest of the ship. How much longer will we be in here?”

Mama surprised us again. “This gestation tank has been programmed to grow the current pair of fetuses to early adulthood, or 21 years of age. The remaining gestational time is 5 days.

ALERT! ERROR DETECTED!

For two to reach age 21 it will require a total of 42 years; therefore, gestation will end in 7,665 days or 21 years and five days.”

The computer’s programming had gone terribly wrong! We had grown to adult size and had educations equal to Master’s degrees! I complained, “Mama, that can’t be right! We’re adults! We’ve been in here almost 21 years!”

The computer ignored me. My twin mentally ‘screamed’, “LET US OUT! THIS IS WRONG! OPEN THE TUBE!”

Mama’s unemotional voice replied, “Occupants of gestation tubes are embryos. The ship’s computer only accepts instructions from adults. Embryos in this gestation tube will be adults when released from tube in 7,665 days. Please begin the next lesson, ‘Advanced plasma physics - part 17’.”

We shouted again and it repeated, “Occupants of gestation tubes are embryos. The ship’s computer only accepts ...

... instructions from adults. Embryos in this gestation tube will be adults when released from tube in 7,665 days. Please begin the next lesson, ‘Advanced plasma physics - part 17’.”

We knew the inside of our cylinder extremely well, and there was obviously no way for us to escape. There were no latches, buttons, or mechanisms within sight or reach. There was a clear plastic lid of sorts, with a light and six small round holes which our umbilicals and hoses ran through. The rest of the lid had hundreds of three-millimeter holes which allowed in fresh liquid when the cylinder was flushed to clean it. I reached up and pushed it as hard as I could, but it wouldn’t budge. The bottom had hundreds of one-centimeter holes to allow our waste out when it was flush time, and eight thin and shiny metal bars supported it from below. We tried kicking it, but it didn’t even move slightly.

The rest of the interior was smooth gray plastic. The only things we had that even slightly resembled tools were our fingernails. We couldn’t even scratch the hard plastic. We tried punching and kicking, but only hurt our fingers and toes. We realized we were stuck until the computer let us out.

A few days later we got another surprise. When I woke my penis was rigid and felt nice, in an odd way. I saw that Girl’s nipples were partially erect too. When we asked the computer some questions, it explained, “Girl and Boy, hormone suppressants are given to embryos to prevent sexual activity until age 21. ...
