... floor and poop near the tank outlet to be cleaner and more polite.

We lived and matured about the same way our parents told us they had. Mama would give us a boring lesson, an entertainment video, and then another lesson. One day I had an idea for new entertainment.

I asked, “Mama, you showed us a game called ‘soccer’ or ‘football’. That looked like a lot of fun. Can we get a ball to play with?”

“Freedom, a soccer ball would float to the top of your tank. You would not be able to reach it.”

“Well, could you weigh it down?”

“I will modify a ball and provide it for your use.”

The next morning there was a ball on the bottom of our tank. I was quite happy until I kicked it experimentally and hurt my foot. “Mama, the ball is really hard!”

“It is filled with stainless steel nuts and bolts, so it will not float.”

“But… but it’s so hard that if we kick it we’ll hurt our feet!”

“You desire a ball you can safely kick? Very well. I will ballast another with water and silica sand instead.”

A short time later, another ball dropped into our tank and slowly sank to the bottom. I kicked it gently and it moved a bit. I kicked it harder and it bounced off my sister Sovereignty’s ankle and stopped near her foot. She kicked it back to me. We had a family game going before long, kicking the ball back and forth. We were having a great time until Comfort kicked the wrong ball by accident.

Mama must have drugged us, because there was a plastic slipper-looking item on Comfort’s foot when we woke and the balls were gone. Mama explained, “I have treated Comfort’s injury. Four bones in her toes and foot fractured. The cast needs to remain in place sixty days. I have removed the balls for safety. Please begin your next lesson, ‘Introduction to the Quadratic Formula.’”

There were some conflicts as we matured. My brother Escape and I argued over who was stronger and started wrestling. I shouted and we froze in horror when he accidentally pulled my air hose most of the way out. One centimeter farther, and I would have drowned. Our sisters argued over who was prettier and wanted us to decide but it was pointless, since they looked exactly the same. We often competed for the best scores on our after-lesson quizzes, too. I was annoyed that Autonomy, Release, or Recess won most of the time.

A few days after all of us were 19, our lives suddenly got much more fun and exciting. One morning I woke with an erection and noticed how arousing my sisters’ breasts were. I gently played with Comfort’s chest and she fondled my fully inflated penis. I saw Escape was doing the same with Sovereignty, and our other sisters were feeling each other’s bodies.

Release rubbed her hand between her legs as she asked, “Mama, what’s happening? I feel… Mmmmm! Uh… really ...
