Marchen Maid Jigoku

Synopsis

The mansion has three maids who only live for their master. However, working hard every day is very tiresome, so when the master is not looking, they take a break. In one of those occasions, they pick a white book from the library, but when they open it, they get sucked inside the book and become trapped in a strange wonderland, in which they will be exposed to a lot of erotic situations without taking off their maid uniforms.
