俺のアレが神聖過ぎて重宝されるんだが！？

Office worker Daigo Igarashi rushed to the bathroom with a stomachache while he was on the road.
As I was nearing the limit, I opened the door of the men's room and took off my pants.

Daigo, who should have entered the bathroom, stands in a strange place with his lower body exposed.
He was summoned to another world.

There are only beautiful women... Or rather, a world where there are only women.
It seems that all the children born are "women" and once every ten years, they invite men from another world to leave offspring.
Daigo was chosen as the important partner.

However, Daigo was a real devil whose personality changed when it came to sex...
Is it really okay to leave this man to the big role of conceiving tens of millions of women?

Daigo's devilish conceiving life begins...!??
