Drain Plant

An artificial monster created to hold men inside her, endlessly draining their semen. This is a mass-produced variant based on a prototype for enlarging the womb to hold the extraction specimen. At some point, the genes were crossed with an angel’s. Imbued with intelligence and a will, she is able to monitor and care for the subject inside her. They act as their own security, catching any specimens who escape. Just like a mother caring for a baby, they supply the internal specimen with nutrients through a tube. They then force the male to ejaculate continually to harvest semen. Once taken inside, most men become crippled in around an hour, unable to do anything but come. In addition, she is able to use harvested semen to fertilize eggs in an efficient manner. [From In-game Monsterpedia]
