Akira Kusaba is summoned to the other world of Rumisia by the beautiful silver-haired woman Lucia. Akira wasn't summoned to save the world... but to help her make money!? Feeling exhausted, Akira begins working part-time in the other world, but gradually he notices the strangeness of this world. There's a female adventurer who wants to have her breasts wiped by a man, a slime that tries to drain the vitality out of men, and even Lucia, who summoned him, forces him to sleep next to her and secretly enjoys solo play in the bed next to her...? Yes, this other world is a world where the concepts of chastity between men and women are reversed!
