As a maid, Anna doesn't have to rush to clean the house or garden at all, her job every day is to serve her boss privately, serve... Sexual activity.
A Beautiful Maid's Day at Work is a Heyzo studio movie, which is as the title suggests, but only in a black way.
It is not wrong to say that she works, compared to the daily work of a maid, Anna also does it, but she does a completely different job than the default. So what does Anna really do for her master every day? Please watch the movie.
