I always had a fantasy to go with my wife on a secluded nude beach. Finally happened last year in Greece. We arrived at the beach and nobody was there. I convinced my wife to go topless ( see first picture) and try the water. As I was admiring her, I didn't notice that another guy arrived and went full nude swinging his junk in front of my wife.
I see her immediately blushed but aroused at the same time. It took some time until I convinced her to go full nude. I get immediately aroused by the idea that my wife is exposed to a stranger. The other guy didn't take his eyes off my wife and I noticed her taking a look at his junk whenever she had the chance. The peak was when my wife exposed her ass crack and pussy.
My only regret is that I didn't engage the guy to see where it leads.
Waiting your opinion on our dare as I can not stop thinking about that event.
