We had already had a couple of great days at the nudist beach. I had watched as on the first day a couple of men wanked themselves off while watching my wife and later in the afternoon a third one, the one with the biggest cock of the day was called closer by my Wife and I watched as she reached up to stroke his cock.
Soon his hands were squeezing her breasts and pulling her nipples and then finally his fingers were working in her cunt as they soon brought each other to orgasm. His cum spraying all over her tits and tummy. While this was going on I had just sat there with my own cock throbbing away, ignored by them both.
Unbeknownst to me she arranged to meet him the next day on the beach. That evening she was stroking my cock which had still not cum, while she told me how much bigger and harder his cock was. She teased me for having a hard cock as another man pleasured his wife. I wonder how hard your cock would have been if I let him fuck me, that was it, with those words I thrust my hips upwards as the spunk flew from my cock.
