During our first party with all 6 of us Mary had dressed up in one of these sex shop "Schoolgirl" outfits. I must admit it got us all going, but Doug whisked her away to our spare bedroom and I got to play with Ann instead. Later on though I did get my turn with Mary after Doug had finished with her. She was still wearing the schoolgirl outfit although the top was up round her neck so her ample tits were on show and her little white panties were long gone.

After we had both satisfied each other and were relaxing together naked, Mary let it slip that she was turned on by being submissive during our sex play and when she was with Doug earlier.. I suggested she should go on line and search the web for things to try.

Mary did exactly that and as time went on she started wearing a collar and lead at our meetings, she would do everything we asked her to, no matter what instantly and even gave Doug and I a cane "to chastise her with if ever she disappointed" She started calling us "Sir" and "Master" during sex play, and would always be naughty and earn herself a few strokes of the cane across her bum. All fairly tame stuff, and Mary was wanting more.

As usual, Kate came up with the answer. We should take Mary dogging. Now that was right outside the box as we were an exclusive group and were always bareback when we fucked each others wives. Kate said that a supply of condoms would of course be needed and we would get Mary tested. Simon agreed that would be OK and even he wouldn't touch Mary until the "all clear" result came in. Kate and Ann readily volunteered to fuck him instead.

What did Mary think about all this? She was a bit apprehensive about security, but we reassured her that one or two of us boys would always be with her to make sure nobody overstepped the mark and she would have a safe word to use if we needed to shut down the session. At the same time she would have the maximum opportunity to try out her sub side by us boys instructing her to do things outside her comfort zone (whatever that might be).

Doug knew of a few dogging sites not too close to home (he would, the old goat) but Simon decided to stay home with Kate and Ann while we took Mary out. Mary was instructed what to wear. We thought maybe a slutty look maybe a bit tarty, but decided against it. Instead, we went for a stylish look with a three quarter length flowing blue dress, matching strappy shoes and a normal world bra and French knickers with hold ups. When she came down from her bedroom and gave us a twirl she looked just like she was off to a posh restaurant for a dinner date.

Simon was still a little concerned, after all he had no idea what his wife was going to be up to. Kate and Ann reassured him that with Doug and me on hand, she was going to be safe and we wouldn't let anything happen that Mary wasn't happy with. The two girls would be more than happy to look after him while we were out. He would be drained when we got home in more ways than one.

Mary Doug and I walked out to the car leaving the other 3 to it. Simon was already playing with Ann's tits while Kate was on her knees doing what she does best. Mary sat in the front, Doug did the driving and I sat in the back.

It took about 45 minutes to get to the first site. A secluded layby off the main road made when the old road was straightened and widened some years back. We arrived as it was just twilight but there were already 3 cars and a truck parked up. A set of public toilets had been built about half way down. We parked up near the other vehicles.

"What now?" asked Mary. Doug had the answer. Us guys would get out and lean against the car while Mary was instructed to get out and walk down to the toilets then walk back to the car as sexily as she could so the guys in the cars could see she was available. We would then get into our car and turn on the interior lights in true dogging fashion.. Mary set off down the middle of the layby between the cars veering towards each car in turn. Once at the toilets, she didn't go in but turned round and slowly retraced her steps to the car.

We got back in our car and Doug flicked on the lights, sure by now that Mary had gained the attention of the other cars.

What happened next you will have to wait till next time to find out.
