Mary, now dressed again, was still horny from her antics with the guys in the layby and wanted more. There was nothing more where we were so Doug drove on to the next place about 15 min away. This was a country park car park with one of those goal post type height restrictions at the entrance, so no trucks or big vans here. Trouble was, there wasn't any cars there either. I guess that's the trouble with dogging. We moved on to a third site. At least there were a few cars there and a van. We parked and Mary got out for her walk. Doug and I got out of the car and went to have a look at what else was going on. The sliding side door of the van was open and a rather mature lady was sucking off the few guys standing around. Mary must have been a good 15 years younger and a lot classily dressed so immediately got the attention of all the males. The older lady stopped sucking and asked Mary if she was there to watch or did she want to play. Mary looked at me for permission. I told everyone that Mary was our sub and we would decide what she did and who with. The older lady told us there was a mattress in the van and Mary was welcome to use it. The older ladies' partner opened the rear doors of the van. I ordered Mary to take off her dress, bra and panties and hop into the van. She did as she was told, much to the admiration of the small group of guys. I picked a guy for her to give a blow job to while Doug picked a second to fuck her, making sure the guy was rubbered up. Mary started to work enjoying the spit roast she found herself in. The older lady now found herself reduced to that of "fluffer" getting the small queue of men nice and hard before they moved on to play with Mary. Over the next hour Mary was fucked and sucked and even buggered a couple of times while Doug and I watched to make sure everybody stayed in order.
Around midnight the older lady called a halt as she and her partner needed to get home. Mary collected her clothes and passed them to Doug before climbing out of the van naked except for stockings and shoes and then finishing off the last 2 guys bent over the bonnet of somebodies car.. Once done she slipped on her dress without the underwear and we walked back to Doug's car to drive Mary home to Simon.
Mary said she thought she sucked off about a dozen guys and fucked 8. I thought it was only 7 but wasn't sure. Anyway it turned out to be quite a successful evening and Mary was still buzzing. We finally worked it out by how many condoms we had left that Mary had fucked 7 guys, but one had come back for a second go, so 8 fucks in total. including the two young guys at the layby earlier. Mary said that if we had told her 6 months ago that she would be sucking random guys in a car park and would fuck 7 strangers in one session she would never have believed us, and would be pissed off that we could think she could be such a whore. We said she wasn't a whore as none of the guys had paid. Mary grinned and said, maybe next time then.
Back at Mary's house Simon was still in bed with Kate and Ann. He looked as fucked as Mary did, so the two girls had been giving him a good time. Just as well said Mary as she had a sore cunt from all the fucking and needed a while to get over it.
Mary jumped into the shower while Kate and Ann dressed. Simon stayed in bed waiting for his freshly fucked Mrs to join him. Doug and I now with our own wives for a change wished them goodnight and we went home.
Over the next few days the girls got together while us 3 guys went to our places of work. I have already told you all we are normal guys with normal jobs. It's just our joint sex lives that are a bit less than normal. Mary went down to the STI clinic to be tested and was given a test which was negative, but would have to go back for a second check to get a final all clear. In the mean time Kate or Ann would drop by Mary's place in the evenings to give Simon a good fucking and keep him happy.
Things then settled down a bit. Mary had scratched that itch and said that while she might do it again sometime, being fucked in the van and bent over the cars was uncomfortable, and by the end she was getting cold. Fucking indoors was warmer and softer on her bones. Both Ann and Kate had fucked in cars and on beaches and other places on holiday or when teenagers and had to agree. Fucking outdoors was exciting because of the spontaneity and danger of being caught, but generally indoors was better. Doug said that a pussy was a pussy and should be fucked whenever and where ever it was available. Ann slapped him playfully
In some ways our little group was getting too comfortable. We were getting too used to fucking each other and even Kate with her curiosity had run out of different things she wanted us 3 guys to do to her. What should we do? Kate and I talked about it on one of the nights we were in our own bed by ourselves. We could expand the group by another couple or two. But who could we choose, and what was the risk of that breaking up what we already had? Any outsider we met for casual sex would have to use protection and even then, there may be a risk to the integrity of the group. Whatever we did, Kate needed more and different cock.
What we did was hire a villa in the South of France for our 2 week holiday, right by the famous nudist beach, for all 6 of us. The guys were looking forward to sharing some French fanny between us while the girls said they were almost certain to sample some foreign cock. They might even let us watch.
Next time I will tell what happened on the holiday at the Cape.
