The Seedmakers are a race of genetically engineered males carefully selected for one thing only: breeding. They are hyper-virile beasts whose colossal muscles and endless stamina power their supermassive sexes into the wombs of the strongest, most fertile females of the Universe. This story follows the sexual exploits of one particular Seedmaker in his quest to unravel the mysteries behind his Creators... and his discovery of another equally fecund, equally powerful race of super females.
