We have a great story for your couples section.
My Girlfreind and I went camping with a group last summer. We shared a tent with another couple, at first we were all a little shy. What will the other couple think if we start screwing? So we just necked and petted in the dark, so did they. Pretty soon everyone was breathing deeply and the atmosphere was very hot, even though it was a cool night. I think the other couple were first to progress to initiating an actual sex act, but their air mattresses started to separate from each other and they started whispering ( more like cursing) and giggling which broke the ice. Before they could actually get to having sex, my girlfreind and I coupled and were going at it. We could have cared less who knew we were having sex.
For the next couple of hours we all screwed our brains out, we never actually swapped, but one couple would be screwing and that would excite the other couple. After we orgasamed, we would rest and listen to the others, then get excited again and start fucking while the others were fucking.
We all chatted a bit when neither couple was having sex, and became quite relaxed. If this had been more than an overnight trip, I think we could have progressed to full swap rather than just same room sex.
We have also attatched a picture of us. It is how we were going at it while in the tent that night.
