Yes, done it loads of times. Just ask politely, even ones that don’t advertise it, they can only say no.
Simple rules are be prepared you might get asked to pay more, obviously your choice if you think it’s worth it or not. The SP might say yes but only on her camera and she will send you the videos and pictures afterwards, again up to you but I would decline at this point - I’ll happily send them my pictures and videos after (and at no cost to them ha ha) and, this leads to my next point, only after I’ve checked them for any identifying features of me being visible.
Remember, once the picture or video is out there it can and will pop up on the internet for years to come. The potential risk is very real. So my final two rules are I control what happens to content I could be identified in and secondly I am not a dickhead about posting trophy shots or videos anywhere. Unless otherwise agreed between both parties, content remains for my eyes only.
All of that said, there are SP’s in the local area who have pictures and video I have shot on their profiles and in their private galleries.
It can be fun, although I’ve seen enough badly shot camera phone footage of blow jobs to last a life time. If you are even half creative, the results can be stunning. Just don’t be a dick with what you do with the stuff you shoot.
