Some of this was planned, but she didn't know. She agreed to flashing the car in a car park, but to make sure it went smoothly I had arranged this with a guy that knew how the plan was hopefully going to work, little did we know how well it would work and exceed expectations. We had gone to a local dogging site, she had had a few drinks, enough to relax but definitely not too much, she her tits out, and as arranged he came past the car, took a glance smiled and walked past. he came back a few minutes later and had a much better look, a conversation was struck up. nothing major happened and he went away. We had decided on a local pub for a meal and a drink, so off we went. Just by 'coincidence' he came in a few minutes after we got there, saw us and asked if he could join us. The wine flowed quite freely and she was nice and relaxed. We had great conversation d a nice meal. When it came to dessert, i asked if anyone wanted dessert, he cheekily said that he fancied Dessert but what he would like wasn't on the menu, she asked what would that be? He said it was some time with her gorgeous tits, he would happily pay the bill if she would agree. She looked at me and i said its just boobs, so why not. She laughed and said Ok then. He suggested that she goes to the toilet to remove her Bra while he settles the bill. She came back a few minutes later, her top unbuttoned a little lower that it should be, leaning over the table towards him, saying is this the dessert that you wanted sir? We left the pub, and went to his car, she got in the back and he climbed in, I sat in the front. he unbuttoned the last few buttons of her blouse, her tits spilling out, he moved over and held them and started to suck on them. they were moving about to get a more comfortable position and i knew that her hand was massaging his cock through his trousers. She said that she wasn't quite comfortable and that she needed to pull her skirt up a bit. He moved around and as she lifted her bottom off the seat he pulled her knickers down. Then i knew that it was a high probability that the ultimate was going to happen. He went back to her tits then his hand went between her legs, gradually moving up, she spread her legs, he mentioned how lovely her shaven pussy was. his fingers spent quite some time inside of her before he said how uncomfortable he was with his hard on restricted in his trousers, he moved up and pulled his trousers and pants down, then moved between her legs, i couldn't see properly but knew that she had hold of him and was rubbing his cock up and down her wet slit. It was at this point I said that I need to pop back to the pub to go to the loo. as could see in the window much better now, she had positioned hid cock at her entrance, he pushed in, started pumping away. I watched so intently as my wife was getting pummelled by a stranger, bareback, no position changes just her legs now on his shoulders him driving deep inside of her, then he froze as he shot his cum inside her. they stayed motionless for what seemed and eternity, He pulled up and i could see some cum drip from his cock, so knew for sure that he had cum inside her. I went to the pub and gave them a few mins to get sorted, came back and they were standing by the car. I just asked did you enjoy the desert, they both ;laughed and said it was very nice. He asked if he could buy lunch another time, she looked at me, wondering what i was going to say, i laughed and said that maybe we should all enjoy dessert together in the very near future.
