Has anyone ever paid extra to either tape or photograph girls in addition for other services or is that a strict no no?
I don't necessarily want to record sex acts but rather just take a photo or two on my film camera. Doubt I'll be going back any time soon but would love to have a few keepsakes from the trip

Why, and what would you do with the photos? What's the point?

This can be done.
Some ads on kinky.nl specifically list video as an option.
I know a few window girls have allowed pictures for regular customers.
I have no idea what this might cost.
The ones that I know of were free.
This is going to be hard, maybe impossible, on a first visit.
