Professor Drex takes place in a richly decorated steampunk setting, where gorgeous female submissives are strapped to a lab table and probed in a variety of perverted ways until brought to orgasm. The professor then requires them to bring his lab assistants to orgasm and use their sexual fluids to feed his warriors so that they may successfully battle the evil Vampire Dominatrix and her minions. Also on this DVD are companion scenes from Ashley Fire’s SciFiDreamgirls series - Lesbian FemBots in Outer Space!
