"What do you think?" my wife asked, turning her head sideways and giving me a look that was both shy and teasing.
"I like it. I like it a lot," I replied as Karen turned her attention back to the full-length mirror in our bedroom. She tugged at the hem of the red dress she had just bought. It was a couple of inches shorter than she would normally wear and ended well above her knees.
I should explain that it had been bought for a specific event. For some years my wife had been involved in a group of local mums and they were all now reaching the milestone of their fortieth birthdays.
In fact Karen was the oldest at forty-two, but two members of the group, Annette and Jayne, had their fortieth birthday on consecutive days and a joint celebration was planned. Annette was the most extrovert member of the group and a weekend away for all the women in the group and their partners had been her idea.
In truth Annette was the unofficial leader of the group and I have to be honest and say that she was a bit too bossy for my liking. There was also an attention seeking side to her which I put down to a family history that included a lot of involvement with amateur dramatics.
Nevertheless she was very friendly with my wife Karen, which surprised me because Karen was a quieter and more conservative person. Anyway I saw a fair bit of Annette and we got along fine, though she wasn't my favourite person and I had a strong suspicion that the feeling was reciprocated.
I might not have been over fond of Annette but her ideas for the weekend away definitely met with my approval. Through a family friend she had got the use of a ten bedroom country house in rural Suffolk and Karen rather nervously told me that the women had agreed that the Saturday night celebration would be themed as a tarts and vicars party.
Karen was worried that I would disapprove of her dressing up in a tarty fashion, but I soon reassured her that wasn't the case. We've been married for twenty years and I wouldn't say our sex life was in a rut, but inevitably some of the excitement had evaporated and a sexy weekend away was probably long overdue.
In case you're not familiar with the concept I should explain that at a tarts and vicars party the women all dress in a revealing, tarty (i.e. sluttish) fashion and the men have to dress as sober, staid (i.e. boring) country vicars. Apparently the original suggestion had been to have everyone in period costume in keeping with the country house where we were staying, but that had proved expensive and impractical, so Annette had suggested tarts and vicars instead.
Karen didn't have a dress which counted as tarty so she had gone out shopping and come back with a little red dress. She was modelling it for me now together with the seamed stockings and the black high heels she had bought. It wasn't hugely revealing, but it was definitely shorter and more low-cut than anything else she owned. In fact as she changed position to check different angles in the mirror I noticed that the slit at the back of the dress meant the lace top of her hold-ups (and indeed some of the bare flesh above that) was easily visible.
I felt a pleasurable stiffening in my penis when I saw that. Not because of the flesh on display, but because I knew the men in our group would be treated to the same view. Karen is a very attractive woman and has kept her looks incredibly well; people are often very surprised to find that she is in her forties.
There had been times when I'd seen some of the other men studying her appreciatively. I didn't feel jealous or angry about that, I liked the fact that I had an attractive wife, but there was another side to it as well.
For some time I'd fantasised about watching another man fuck my innocent wife. Eventually I plucked up the courage and told Karen. She was shocked, but to my relief she wasn't upset, though she did say it wasn't going to happen. Nevertheless the idea of including another man in our lovemaking did become a regular item of pillow talk and invariably got both of us pretty aroused.
Of course all this was running through my mind as I watched Karen checking herself in the mirror.
"You're sure it's alright?" she asked me again. "I'm not showing too much am I?"
"No, all it shows is that you've still got a great figure." At that moment she bent over to pick up her hairbrush and I was treated to a great view down the front of her dress. I could see her 36D breasts nestling in the cups of a black bra. God I love her tits. They're world class, full and satisfying with prominent nipples and large, dark areola.
"And when you bend over it shows you've got great tits," I added with a laugh. She came across and aimed a friendly blow at me, I dodged and tried to grab her, but she skipped away.
"Oh no, you're not messing my new clothes up," she laughed. Not now I thought, but if I had anything to do with it they were going to get thoroughly messed up at some stage.

"What do you think?" I asked Steve and Martyn. "I reckon we have a very good chance."
"I'd say it's pretty certain," said Steve with a confident grin. "They're experienced married women, they know what it's for. Think about how they've set this up - the clothes, the game. There's going to be a lot of sex tonight, what we can't predict is who and when."
Martyn didn't look convinced, but I had to agree with Steve. We hadn't pushed or prompted the women in any way; it had all been their idea. I'd got the first surprise when Annette had come up with the idea of a tarts and vicars party. The major surprise came however when Karen had shown me the red and black garter she had bought.
