My buddy Steve and I were out drinking late one night, and the conversation fell around to girlfriends, I thought his girlfriend Sheila was a stunner and I had never made a secret of the fact to Steve.

But until he told me that night, I was not aware that he had serious hot’s for Karen, my girlfriend of two years, I made an off-the-cuff remark that we should swap them for the night, which was just one of those stupid drunken things that you say.

Anyway, the week later, we are back at the same bar, and Steve says to me that he spoke to Sheila, and she would be interested, and had I asked Karen? Well, I hadn’t, as it was only a joke, so he said, “well maybe I should ask her.”

I found the right moment a few days later and asked Karen if she was attracted to Steve and would she sleep with him she was single, to which she replied “in a heartbeat” I told her about stupid drunken conversation, and then when she didn’t react badly to that, I told her about second conversation.

That weekend, Sheila invited us around their house for dinner, it was obvious all evening, what all four of us were thinking, and I also had a feeling that the two girls had had a conversation behind our backs about the situation.

I figured this because after a few hours Karen said that we were staying overnight, then Shiela said she was off to bed, well, my heart sank, but it soon picked up again, when she looked me straight in the eye and asked if I was coming with her?

That was the first time that we had swapped partners, and I have to say it was amazing, Sheila was every bit as good as I thought she would be, just amazing in bed and so sexy.

Our relationship was carried on since then, and our friendship has got even stronger, the four of us are always seen as an item now, but I don’t think anybody realises just how close friends we are.
