Here's the story about David and my first bisexual encounter. I've exaggerated some, but it's basically true.
We were with couple named Rick and Jennifer. They had invited us over to Rick's parent's house who were gone on vacation. We had been camping with Rick and Jen a couple of times and had always found a secluded place to go skinny-dipping which David and I really enjoyed. Both Rick and Jen were very attractive and these naked encounters with them had become fuel for many many fantasies for us. David and I had had a few frank discussions about sex and both admitted to having fantasies about bi-sex. I'd only experienced a few light petting experiences with a girl friend of mine. David had participated in a few circle jerks with friends in college and one guy had even sucked his cock but that was all.
We didn't think that Rick and Jen were thinking about us in the same way. Yet, Rick was always pretty open about displaying himself in front of us as though he liked to show off. And Jen was very affectionate with both of us, always hugging us both and was very expressive with her hands. That, I'm sure is what turned me on about our friends.
Anyway, Rick's parents had a big house in the foothills that had a beautiful secluded pool. Naturally, it wasn't long before we all were naked and enjoying the pool and the sun. We were drinking wine coolers and frolicking around in the pool, playing games that naturally brought about quite a bit of physical contact. It wasn't long before I was really feeling very horny. After a while, Jen and I got out to sun on lounge chairs.
As we lay there, I noticed Jen kind of staring at me and when I looked over, she laughed as she said how much fun it was to have us over. I'm sure I was blushing as all I could think of to say that we loved being there.
