a FWB I'm seeing regularly told me she would enjoy getting photographed, both as a just erotic photo session and while getting fucked.

I've never done this kind of photography, but I'm incredible turned on by the idea. I have a 50mm and a 20-80mm. What should I use? What are some recommeded poses to shoot? I really like closeups, so I was thinking on shooting some "classy" b&w bokeh of specific features of her such as her lips, ass, shoulders, etc. Any tips someone with experience can give me?
