Of course the first The Secretary. This is really an awesome movie. rumor has it there is a Secretary two coming out. The spanking scene is really hot.
The other would be. The Pet.
This is a Movie about a man who takes a young woman and turns her into a human pet. I did not care for the story line of the movie, being that is was Human Trafficking , but what I did like about the movie was, the devotion both had for each other.
Both are on netflix.
