On a naturist beach on Lake Geneva, in the Villeneuve reedbed, my sister-in-law is lying on the sand, her head resting on a piece of driftwood. We are both over seventy, with wrinkles, stretch marks, and all the skin imperfections typical of our age. My sister-in-law is naked and has small breasts with large areolas, her breasts are sagging and flat. She has very wide hips and strong legs, as well as slightly thick ankles. Her gray hair is cut in a bob. She has a large, flat bottom. Her pubic area is shaved. Her labia majora are exposed, long, and pendulous. Next to her, I am also lying on my back on the same side, my head resting on the same tree trunk, and I am masturbating while watching her. In the background, the reedbed stretches as far as the eye can see, naturists are watching us.
