This happened a few years ago, but I decided to add to this collections by writing something that happened to us. We live in Adelaide, South Australia. We drove way south to a nude beach called Maslins. We spent the day, naked in the sun, conversing with several people, friendly chat and so forth. We got up and walked along the beach, stopping to talk with a guy sunning himself. He was a polite guy, mid thirties I would say and he was an English tourist. We then moved back to our spot and continued for the rest of the day enjoying the sunshine.
Around 5pm, we decided to go home, so we walked the long flight of stairs back to the car park. When we got there, the Englishman also arrived at his car, ready to leave as well. I noticed my wife looking at him, so I asked her did she want to do anything. She said she would like to go talk to the Englishman and ask him if he would like a BJ (blowjob). I said, go for it.
Anyway, I got into my car and watch as she walked across the carpark with just a towel wrapped around her naked body. I watched her talk to him, then both got into the back seat of his car. I sat there having a smoke and occasionally seeing her head pop up for a few seconds before disappearing again.
After about 10 minutes, she got out of his car and came back to our car. I saw other people had also watched the event and smirked at her as she walked back.
She got into the car and gave me a big kiss(which was somewhat salty), before I asked her how it went, she said it was great. She said while she was sucking his cock, she realised that she would have to swallow his cum so not to mess up his car. She said he had a lovely cock, right sized for her mouth and enjoyed giving an anonymous blowjob with so many people in the carpark watching.
I was so proud of her for taking the initiative to be the little cumslut cock sucker she is and gave her a hug and proceeded home. I wanted to her to give me every detail, to which I had a hardon for the whole drive home.
