This story happened on my last holiday when I was at a nude beach where I met a German woman.
This story happened last summer when I was alone on a holiday visiting the local nude beach. It was my first time there but after a while I felt so comfortable that I started talking to other nudists at the local bar.
That's when I men Anna; she was a 62-year old German woman who was also spending her vacation alone. After 2 hours, around 6 pm, the beach was getting empty. Suddenly Anna asked if I was aroused because my balls were so swollen. I wasn't actually, but my genitals are quite large. After I told her that it was normal, she complimented me and asked if it would grow when I was hard. Since it is, I slowly started stroking myself as she watched curiously.
It felt quite strange, being watched while masturbating, but it also turned me on seeing this woman staring at my penis and balls. When my cock was hard, I showed there that the skin around my genitals was very flexible. Without asking, she let her hand slide over them, which felt incredibly nice. I softly continued stroking as I felt her hand massaging. Occasionally I let her stroke me as I was trying to get her horny. I started fingering her while my other hand was touching other parts of her body.
Eventually I came all over the place as she kept one hand on my balls, enjoying the process of my orgasm. Shortly after I climaxed we said goodbye, sadly I didn't see her again later that week.
