... she woke. “Boy, I don’t know what, but something is wrong. I don’t feel right. Mama, can you check me please? I think maybe I’m sick.” Mama said, “You have nothing to fear. I removed the fetus to prevent any negative impact on your health.” “You REMOVED IT! My baby! NOOOO!” “Your offspring is now growing in the tank next to yours. So far, she is a healthy female.” I hugged Girl and excitedly said, “Female! We’re going to have a daughter!” Girl calmed a little and lamented, “Yeah. If we ever get out of here.” Mama asked, “Do you have a name for her, or shall her designation be Girl Two?” We thought a moment and my twin said, “Liberty. Her name is Liberty.” - After a few more months of boring lessons and happy sex, Girl was pregnant again. After telling us, Mama said, “To prevent another panic, I am informing you now. When the embryo is sixty days old, I will remove it from Girl’s body and place it in an incubation chamber. As a reminder, sex is not allowed. Please do not have sex.” Girl and I just chuckled and shook our heads. Over the previous half year we’d fucked at least five times a day, except the day Mama took out Liberty. Girl asked, “Mama, there are a total of four gestation tubes on the ship. Right?” “Yes, there are four, all in the same compartment.” “If we have three embryos in the other three cylinders, what would happen if I got pregnant again?” “Other than twins, each embryo needs to be in a cylinder by itself.

I would need to release you before your scheduled gestation time had elapsed. If you remain in the tank while pregnant, eventually the demands of your body and a nearly mature embryo would be too great to supply with only the umbilical and feeding tube. Therefore, you would be released.” We both shouted and waved our arms in triumph. “WOOOOO!” “YES!” “FREEDOM!” - Just before bedtime I looked in Girl’s eyes. I said, “We’re starting a family and I love you so very much. There’s not enough space for me to kneel and I don’t have a ring. But will you marry me?” Nothing ever made me happier than her reply of, “YES!” - Several weeks later Mama gave us an update. “Boy, Girl, my last pregnancy health assessment was only partially accurate. Girl is pregnant and there are eight embryos inside her, octuplets. All are at the expected size for 60 days’ gestation.” At the same time, we demanded, “WHAT?” “Her uterus contains six female embryos and two males. This is a significant problem. The maximum capacity of an incubation chamber is two human fetuses, and two of the four incubation tubes are in use. Your offspring have grown too large for cryo-stasis. You must choose the two new offspring you wish to keep.” “We can only keep two? NO! NOT OUR BABIES!” “NO! And why only two?” “The umbilicals are attached to a single ...
