I Masturbate For My Sister

I went to a naturist camp in Devon for a three-week holiday and returned with a good sun tan all over. My sister, Edna, who lives near me, visited me to ask about my holiday. I told her that I was brown all over and she asked me to show it to her so I undressed in my lounge and, totally nude, let her look at me. Being stark naked in front of my sister (a new experience for me) I began to get an erection.

"Your cock is growing, Peter. Show me what it looks like right up".

I stroked myself until my cock was fully hard and Edna said it was pretty big. Could she have a photo of it? The light in my curtained lounge was not good enough so we went out on to my lawn where I got myself to full erection again. I gave Edna my digital camera and she took a photo which I said I would print for her. Then she said she would like a photo of me cumming. That shook me but I was very willing to masturbate because I was close to ejaculating when I got myself to full hard-on.

I stood sideways to her and told her that I would call "Now" when I was about to cum. I did that and she took several photos immediately. I ejaculated in streams and when we looked at the pictures on the camera screen the first one showed me before I ejaculated but we were pleased with the others. Edna now has photos of me with an erection and several of me cumming.
