My husband and I were on vacation in Tenerife, Canary Islands, and decided to visit a nude beach we had read about. We drove down a narrow, winding road to a small parking area, bought a pitcher of sangria at a little stand, and walked along a footpath to a secluded beach.
There were quite a few people there, of all ages, and most of them were naked. A few women wore bikini bottoms and one or two obvious tourists - like us - were self-consciously still in their bathing suits.
We found a spot to spread our blanket and sat down with our pitcher. After a glass of sangria, we felt much less inhibited and peeled off our suits. It felt good to be completely naked in the warm sun. I was already a little high, which helped me shed my inhibitions, along with my clothes.
The couple nearest us appeared to be in their early 30s, a little younger than we are, and very good looking. They might have been European, because I couldn't help but notice the guy was uncircumcised. They were lying on their backs with their eyes closed, and the woman (his wife, I assume; they wore wedding rings) began playing with his right nipple.
As I watched, his nipple stiffened, and his cock began to thicken and lengthen. Gradually, the tip started to protrude from under the hood of skin. I felt a thrill of excitement shoot through me, and my own nipples hardened. I wondered if she knew her husband was becoming aroused.
I looked to see if my husband noticed what was happening, but he was turned away from me, apparently watching a young woman with large breasts tossing a ball with her friends. I turned my attention back to the amorous couple.
His penis had grown considerably and now was rising, as well as getting longer and thicker. He also had begun to return his wife's favor, rubbing her nipple between his thumb and forefinger. I was getting really hot, and very much wanted to touch myself, but I didn't.
Instead, I nudged my husband and gestured for him to see the foreplay taking place next to us. His mouth dropped open and his own cock immediately began to respond. Seeing that inflamed me further.
As we both watched, the woman kept massaging his nipple and the guy's cock continued to grow until it stuck straight up in the air. His erection looked to be longer than my husband's, which I've measured at 7 inches, and it was extremely thick. I desperately wanted to stroke it. Instead, I reached for my husband's cock and felt it swell in my hand. He started to stroke my thigh.
