As a maid, Anna does not clean the house or garden at all; her daily job is to serve her master, serving... sex.
A Day in the Life of a Beautiful Maid is a film from the studio Heyzo, with content that reflects its title literally.
It isn't wrong to say she works; compared to the usual tasks of a maid, Anna does perform work, but it is a completely different job from what is expected. So what exactly does Anna do for her master every day? Please watch the movie.
