I’m a bit late to this, by several years in fact, but I just discovered the blooper reels that kink.com occasionally publishes. There’s one from 2008 available here, a 2009 one here, a 2010 one here and one from July 20011 available here. Despite kink’s claims to the contrary, they are not ‘laugh your ass off’ funny and sometimes its hard to figure out what the issue actually is. However, it’s always interesting to see the curtain pulled back and catch performers reacting naturally to unexpected snafus.
I think my favorite moment would have to be in the 2009 clip, at around the 5:30 minute mark, when Dia Zerva and Amber Keen just can’t stop laughing. It’d be a good sequence to show the next anti-porn campaigner who claims it’s all made my abused victims of the human trafficking trade.
