めるふぇんメイド地獄

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.
