I was living and working in New York City at the time and had just moved into a new apartment. While taking out the garbage one day I ran into a rather attractive woman about fifteen years older than me. We started talking and she invited me up for coffee about 10 minutes into the conversation. I accepted, figuring that this may be a good way to get to meet my neighbors.
After arriving at her apartment she sat me in the living room while she fixed the coffee. Naturally I started looking at how she had the room decorated. It was interesting to say the least. There were a large number of statues and photographs of nude men. When she came in with the coffee I asked about the decorations. Oh yes, she said I am an artist and photographer. I either took or sculpted all of these.
A little wile later she asked if I would sit for her. I had never done anything like this but after some convincing I agreed. We went into her studio. She took several pictures and then asked me to undress. I was to be facing her when I removed my shorts so she could get a good clear shot on my penis. After removing all of my clothing I stood there facing her. My penis had remained limp through this whole thing. It is long and thick and my balls hang lower than most. She staired at it for several seconds and announced that she wanted to shoot it hard. Several cameras were setup including a video camera that she could use to make stills from. She started the camera rolling.
Like magic I started to get hard. To increase the stimulation she removed her dress and stood there nude. She took several closeup stills of my foreskin retracting and the totally exposed head of my dick. Then with the video going she sat back in her chair and started to self gratify herself. Then she told me that she wanted me to beat off and aim my cum at her.
I started stroking my dick with long slow deliberate strokes. At first I felt funny doing this in front of another person. Then it became exciting. The more I pumped the more excited I became. I guess she could see the expression on my face and said don't hold back let it go. I did and a long white rope of cum gushed from my cock.
About three weeks later she invited me to her apartment to see the photos. When I arrived there was a small group of people there. She introduced me as the star of her latest show. That was interesting, I never had my dick touched so many times. The photographer came over and told me that I had made quite a hit and I was going to have to put on a show. I was going to have to strip so everyone could see my dick for them selves. After taking my clothes off I walked around the party letting everybody play with my dick. Then she asked if I would stand in the middle of the room and beat off. At this point it didn't matter any more so I did.
When I ejaculated one of the girls collected my cum in her glass and drank it.
These were the two most interesting masturbation sessions I have ever had.
