Malenia, a woman plagued by infertility and betrayal, is sold by her husband to his boss for a promotion. Saved from this fate, she finds herself isekaied to another world as an F-rank dungeon master. However, the class she must choose is far from ordinary-it is explicit in nature. Despite her isekai journey, she can freely travel between both worlds. Explicit content warning!! This story is really lewd, and degenerated with plot.
