I accompanied my friend to a photoshoot ion a gorgeous penthouse with huge floor to ceiling windows- and as soon as I saw them I knew what i wanted to do. While she and the photographer were shooting in another room I quietly set up my camera and nervously start playing with myself in front of the windows- I wonder if the people walking by on the street caught a glance? As i get closer to cumming I have to remember to keep quiet- I don't want to get caught!
