This is not behind the scene. Why producers just copy on and on same script. "Oh yeah, oh fuck yeah and fake whining, Real reactions are most hot. Tiny whimper or just heavy breathing or what ever is best when it's real. Talking, laughing whatever as long as it's real. I want to see real reaction of girls when they are fucked. Gonzo style but better quality. Girl talking to camera-man or director with a dick in her ass is the best.
