Ichiro, an ordinary otaku working adult, is summoned to another world, and is unusually powerless for an "outsider." However, he has actually "awakened" to the other world as the owner of "incubus powers," which allow him to control women through his semen. When Ichiro realizes this, he uses his incubus powers to seducing beautiful women and girls one after another, and eventually rises to the position of king of a country...!?
