... strange.” “I am conserving the supply of hormone suppressant. You are scheduled to take courses on human reproduction today, but I must advise you, sex is not allowed.” Our mother Girl laughed and told us, “Ignore her. It’s your first day as adults. Have some fun!” We watched the lessons and Comfort and I followed along as the man and woman in the video pleasured each other with their hands. I thrust into her as the man in the lesson did the same with the woman. I’d never felt anything so great before!

A month later Mama informed us, “All nine females in the modified water tank are pregnant.

Mama complained, "I must advise you again, sex is not allowed. Please do not have sex." My parents and siblings laughed and ignored Mama, as I did. My brother and I joyously became ‘motherfuckers’, as four of our sisters gave our father a euphoric reverse gangbang. - The computer ‘Mama’ hadn’t malfunctioned in the way the captive humans assumed she had.
