Des extraterrestres capturent un homme pour produire du sperme - edging, jour 1

The year is 3000. Men have destroyed the earth and all of civilization. An advanced race of dominant Women have stepped in to create a new and improved version of the Human Race. The surviving Men are captured and kept incubating in cocoons. Needed only for their sperm. They are submitted to long daily "Edging" sessions for maximum production. But allowed only one semen harvest every 180 days.
