When I was 19 years old, I had a small part in a fetish porn film. The opportunity came about because at the time I had just started community college and had met this guy who was a producer the porn industry. He was telling me about his porn career before class one day and I jokingly said that he should put me in a film. A few days later, he gave me a piece of paper with directions to a shoot. He told me that I did not have to participate but if I wanted to come and see the filming, I could.
I went to the location on the paper and met up with my acquaintance from College. The set was not as glamorous as I expected, it was just a normal house out in the desert. There were 3 girls in the house, very pretty girls but as I remember it they were not girls that you would see on the street and immediately turn your head. My friend was also there of course, along with a very tall guy with a hairy chest who said he was the director and then a few other people.
