FUCK - What have I done !? In Poland for porn casting

I was in Poland for a pair of days and was just about to go into the city centre. A guy approached me on the street and asked me if I wanted to do a casting. Why not, everyone wants to be on television. He also seemed really nice and said that it was harmless and that if I wanted to, I should just come round. I didn't think anything of it and went straight away. When I arrived at the flat, the guy asked me if he could leave a camera running on the side. I didn't mind and off we went. He first asked a pair of normal questions and then things got a bit more "raunchy". Whether I could imagine nude scenes and how far I would go. As I'm an open guy, I have no problem showing myself and suddenly he wanted to see more. I thought nothing of it and showed him my breasts. But it didn't stop at the breasts and then it came out. It was about a porn casting and I didn't know what to say at first. I was suddenly sitting nude on a couch where women were being advertised for sex films.... I thought about what I was doing and then this happened!
