「Please marry me and become a Demon Lord」

Suddenly a young man was kidnapped by a big-breasted, black-haired beauty who called herself 「Demon Lord's Woman」. He was given a job, that is to impregnate her succubi, fairy, and demi-human subordinates.

「Now would you impregnate me first?」

She asked so with a blushing face, there is no man that would say no……

With the ability of Absolute Impregnation and another hidden skill, the young man starts impregnating women in this fantasy world. It's that kind of simple story.
