Funny, don't you think, that once you try something the floodgates get opened.
For Karen, my long time partner, and I, that's exactly how it was.
We had managed to share a long-held fantasy of ours when we met a man from an internet dating website and got entangled in a wickedly sinful threesome.
For me it was an experience I could easily have been satisfied with having, and walked away. But Karen had got a taste for breaking some taboos, and she wanted more.
Since the threesome with Steve our sex life had exploded into this wild beast. Every time we had sex we would talk about the threesome, me describing how the sight of her impaled on his big cock excited me. Her telling me how liberating it was to fuck in front of me without guilt and with the realisation that she could let her inhibitions run free.
But when I arrived home from work one day to discover her on the computer chatting to another couple, I had my doubts.
Getting the sexual dynamics working with one extra guy who was already horny was one thing, getting it right with a couple was another altogether.
But when Karen showed me the text of the chat session (now two hours long by the way!!) it soon became obvious her planning was well advanced.
The chat had started along the usual lines, hello, your name, my name, age, where you live, children etc etc etc.
But then it had taken a turn for the hedonistic.
After gentle prompting from the pair, called Don and Michelle, Karen had described in intimate detail our threesome.
But to my surprise she had also described a piece of her past that was new to me: A lesbian affair from her university days.
Now every red blooded male will be sitting there nodding in agreement when I say this was all good news to me.
Now I could describe in great detail what happened next, but to cut a longwinded story short, it was a week later I found myself sitting in a lounge chatting with this gorgeous blonde called Michelle.
In the distance I could her Karen laughing at a joke told by Don.
