Fantastic thread. I too worked in shop that developed photos in the days they had to be sent off. I had a couple of experiences where hot photos were developed. In one case it was a local girl (over 18) who'd let her boyfriend take some very good pics of her naked and spread. Sadly I couldn't make copies without sending them off so I just had to enjoy her in the moment. However, she often came in and she'd sussed what I'd seen... She still lives locally and I love that I've seen her naked and spread.
I did have a rude awakening when an ex and I took some very hot photos of her naked, spread, playing and sucking. The photo company invited some of their outlet staff to an open day of the processing factory. We saw where the 1000s of prints were developed and travelled on 25m belts across the factory in plain site of the workers. My ex was on the visit with me and was a very distinctive redhead... A few of the staff quietly pointed and eyed her up as we walked around. No doubt they'd seen her in all her glory displayed as the prints ran the length of the factory. I'm sure her prints were copied and she was wank meat for quite a few of the blokes there...
