I had arranged a meeting with a couple. We had said what we all liked prior to the meet. Had done so in the past, so didn't think anything unusual. When I met them, both were completely nude, and we were quickly in bed. She started sucking me and he started to fuck her. After a bit of a suck, which was very nice, she moved up and kissed me. What a kisser, it was the best I'd ever experienced. He stopped fucking her and I went down on her. I quickly found the spot and after 5 minutes or so I had her cumming hard. I let her calm down and asked if she wanted more. She lay on her back and I went down on her again.

I was in the middle of doing this, which she was clearly enjoying from the sounds being made, I felt someone playing with my arsehole. I thought, OK, it feels good, it was never mentioned in discussion before, so I let it continue. Then the play became a bit more intrusive, until I felt something cold there. I'd never been in this particular situation before, but I was having such a great time making her writhe and moan, I just let it happen.

Suddenly, I felt some pushing at my hole, and then it just went in. Oh my god, it was his cock. It was a nice size 8" when I saw it going in and out of his wife, but now it was in me. He had obviously used a lot of lube on me as there was only a slight amount of pain giving way to a new pleasure I had not experienced before. Once he was in all the way he gently starting going in and out. I had not objected or moved my position, and couldn't believe this was happening. It had made his wife a lot more vocal now and she came over my face in great gushes. I maintained my position, and kept up my licking, meanwhile the fucking I was getting was getting quicker in speed, until one big lunge and he let go in me.

I had never even thought about it, but in a short period of time I had become bi.

I ended up fucking the wife and he had sloppy seconds.

I did meet her again, but he was always away on business, so I never got a repeat. But I live in hope.
