I misinterpreted the question.
Got chatting with a complete stranger waiting for a late train. Told me about her part time job as a life model posing at an art college, naively imagining I'd be shocked. Then turned out she was on her way back from a nude shoot for a porn company and been offered a role in an upcoming porn film. I think she was bursting to tell someone, was keeping it quiet from friends and even her boyfriend. Think I first joked about rehearsals. Long story short, met up couple of days later not really expecting anything only to find she'd a video camera already set up in her bedroom.
That was my first experience of porn.
She was literally tall slim busty and blonde almost half my age. Hardly ever mentioned it to anyone since - sounds impossibly unlikely like the crap script for a porn film. Truth can sometimes be stranger than fiction.
