I wouldn't consider it naughty if she sucked my cock while I took photos.
On e other hand I have taken photos of a cuck's wife with him present. I used his camera & it was their thrill for her to pose for another man.
It wasn't anything more than photography & I was happy to oblige.
I started taking pics with her clothed & gradually getting undressed. She changed lingerie a couple of times (in front of both of us). When she was comfortable being nude during changing she stripped off for the camera.
It was very enjoyable for all of us.
