the first part of this, the background will seem a little slow. I am 42 my wife liz 32 she is tall 5'6 slim size 10 34b breasts long legs firm little arse. I thought I was doing the best for us working a lot of overtime and shifts to make a nice home. However after time I became tired at home and it would seem neglecting lizs other needs , her high sex drive. she started to have an affair last christmas with someone we know and i found out. After a heated discussion she agreed to stop the affair but pointed out my neglecting her needs. I agreed that i was wrong and discussed her having sex with other men but not people we know as an extra for her. she thought about this and we agreed on it. so decided to use the internet chat rooms, sites like this etc. we have several large towns near us but live fairly rurally in the middle of robin hood country. to ensure she was safe i would be present in some way at the first meet. so the first meet came early this year in the hot spell March, April time. she agreed to meet a guy from 30 miles away at a pub half way. she got ready white lacy transparent thong matching bra short white skirt and a tshirt top. shaved legs pussy with a little landing strip we drove to the pub as we got near I got into the hatch back boot in case he saw us pull up and she drove into the car park. after what seemed an age i crept out of the boot and went into the pub, wasn't long after in reality. i bought a drink looked round and saw here sat down with a stocky guy few more pounds than he had stated about my age 40's. i had only had a couple of mouthfulls when they got up to leave. i quickly followed them noting his car an old white rusty rover thing and made a mental note of the reg. got in our car to follow. they only went about 1/2 a mile to the nearest car park in the woods. i didnt follow them into the car park i drove past to a layby. i gave them some time then walked into the woods from another track to get near to the car. when i got near i could clearly see a foot against the window white thong around the ankle the car was moving and when i crept up to it all i could see was this large bum bobbing up and down all those mixed emotions many talk about came over me as the obvious was happening the other side if this white mass was the guy fucking your wife. along with the stomach churning, the dry mouth came my own erect cock it was erotic i did think can she breath as he was about 16stone in weight to her just over 8 stone. the signs became apparent he was close quickening then the 4-4 big thrusts . i quickly went back to our car and the pub liz arrived back came to me and wanted a drink. we sat down where they had been sat the barmaid/landlady giving us a strange look. i said i didnt think he would be her type and it had been a bit quick she replied "he wasnt, he was fat and we had agreed it was to be just sex no affair." she was so worked up about the meet anything with a cock would have done. with the background its a little long winded but this became the first of many such meets, which with the background now out the way i can describe better if you wish
