Do this.

Get violent in the sexporn production until the young woman starts screaming for help. Continue this for approximately 30 seconds. Then stop the production and say "Psyche! Just kidding, baby! But since you were such a good sport, we are going to add an exctra $850 to your paypacket." Sell it as entertainment, unedited footage, what fades to black as the young woman laughs nervously through still drying tears and says "You guys scared the shit out of me for a minute!"

I thought Max Hardcore already does this, except he edits out the "Psyche!"
