It is where you take the time to plan your masturbation session, meaning it involves thought from well before. It indicates the type of porn and porn stars etc are thought of in advance (YOU MUST BE EXCITED FOR THIS). You must be able to watch it with the sound at optimum level and have all videos (downloaded or streamed) ready to watch before you start. You should have the house to yourself so you can pleasure yourself however many times you feel necessary.
