My wife, Kim, and I have always had a great sexual relationship, probably because Kim's attitude is that virtually anything goes between consenting adults. We have both logged in to various erotic story websites, and enjoyed many of the stories that we found there. The biggest complaint that Kim has with these stories is that either someone winds up playing a silly game and it goes further than anyone thought it would, or everybody gets drunk and fucks. Her comment on the drunks is that most of the men wouldn't be able to perform worth a damn if they got that sloshed. So it wasn't a real surprise to me when she decided to write her own erotic stories.
She wrote a few stories and posted them, getting a reasonably good response, but she still wasn't happy with the way the stories were going. She did get quite aroused while she was writing them, and that resulted in very good sex. In fact I begin to encourage her to write more, because she often wanted to try things out before putting them in her stories. Kim actually got the most aroused when reading, or writing, stories in the swingers, group sex or threesomes categories. As we had never participated in any of these activities, she felt she couldn't really write a good story about something that she hadn't experienced. It frustrated her a bit, and she would start story after story, but not finish them.
Finally, one night after we had watched a porn video, then made love, she got out of bed to use the toilet, and when she came back she told me that she thought we should try to experiment with swinging, or group sex, at least once, to see if we really were missing anything. I kind of hemmed and hawed a bit, and finally asked if she thought this was really a good idea. While it might give her a basis for her stories, I wasn't sure that it was all that necessary.
"The thought of watching you with another woman has intrigued me for quite awhile. In fact while we were having sex, I kept imagining watching you having sex with another woman, and while I was doing that, someone else was fucking me."
The discussion went on for several days, off and on, and we finally decided that we would try it. The question, of course, was now how do we try it.
We decided to make a list of the people we knew that we would want to go to bed with. We sat down over a drink or two, Kim making up her list, and me mine. After we finished them, we exchanged lists, and when Kim had scanned my list quickly, she started laughing.
"Well, I see I don't have a problem with you deciding to leave me for a woman with big boobs."
"Huh?"
"Not a single woman on this list has breasts any bigger than mine."
Kim was right. "Well, you know I have always told you that I preferred yours."
We went over the lists, combining them, and finally came up with three couples that we thought we would like to dally with. Kim then told me to let her set the stage for this, and I agreed.
Mark and Mel
A couple of weeks later, Kim called me at work and asked if I minded if we had Mel and Mark over for dinner on the following Friday. Of course I agreed, and didn't think anything more about it until I got home from work on Friday. Kim was already home, and as I walked in, she told me that I had about an hour to get showered and cleaned up before our dinner guests arrived. I had completely forgotten about the dinner, and was a little puzzled by the way she was dressed. Kim had on a red silk dress I had never seen. The dress fit like a glove, outlining her breasts, making clear that she hadn't bothered with a bra tonight. The dress was slit up both sides, nearly to her hips, so when she walked, it was clear that her legs did indeed go all the way up.
"Is this a special occasion, or what? I don't remember you dressing up like this before, and certainly not like that."
"Well, you might just get lucky tonight, and we could try out our new ideas."
"With Mel and Mark? Just how do you propose to do this?"
"I've kind of felt Mel out a bit over the last couple of weeks, and I think that she might go along with it. I have at least gotten her to think about it. I haven't actually proposed anything yet, just a bit of girl talk up to now. Just let me handle it tonight."
Now while Kim is my idea of gorgeous, being petite, but perfectly shaped, Mel would catch any man's eye. She is tall, only about an inch shorter than I am, with long, long legs and breasts that seem as though they were sculpted. Mark is a little bigger than I am, and an extremely gentle man, and I would suppose that women would think he was good looking. Extremely intelligent, and a good talker, I have liked Mark since I first met him, although I was a little concerned that this might break up a good friendship. I said so. I guess I was starting to get cold feet.
"No, it won't go to that point, let's just see what happens."
I shrugged and went off to do as I was directed, returning just in time to set up the bar before Mel and Mark arrived.
When Mel and Mark arrived, Mel seemed a little surprised by what Kim was wearing, as both Mel and Mark were wearing the kind of clothes that they normally wear when they come to our home. Mel was in a skirt, cut to just slightly above her knees, and a white blouse. Mark was just wearing slacks and a shirt, like I was.
We did nothing out of the ordinary, having a drink before dinner, then wine with dinner – nothing we hadn't done numerous times before. When dinner was finished, Mel helped Kim clear the table, then we went into the living room to wait for the coffee that was brewing.
We had been chatting about nothing in particular for a few moments, when Kim announced that she wanted to extend an invitation to Mark and Mel. Figuring what was coming, I cringed inside, but didn't say a word.
"Mike and I have decided to try sexual relationships outside our marriage. We have also decided, because we like you both so much, that we would extend an offer to the two of you to join us in our experiment."
At this point, Mel started to say something, but Kim held up her hand;
