My wife and I had not got on too well for some time. We argued a lot and even occasionally walked out of the house to get away from the rows. She was a real stunner. 39 years old, 5 feet 7 inches tall, long, well filled out legs with a good sized round arse to match. Her tits were just as exciting, large, round and well formed. She tended to wear tight sweaters which showed off her large tits. I think it gave her a secret thrill to see men gazing at them. She also tended to wear tight skirts, probably for the same reason, to show her shapely legs and arse off too. Don’t get me wrong. She would not tease a man. You couldn’t get her to do anything outside of marriage, even though we had not had a good sex life ever. I tried every now and then to bring the subject of her having sex with another man, but I never got past the first two words before she would tear into me saying how little I thought of her. So I never was able to get anywhere near to talking to her about having sex with a stranger, something I would have loved her to do. One night, quite late, we had a real humdinger of a row. At about midnight she stormed out of the house, got into her car and drove off in the most furious state I have ever seen her in. I got a bit worried about her because she was capable of getting almost out of control and she was driving a car, probably at high speed too knowing her. I decided to race after her and keeping my distance follow her just to see she was alright. Fortunately for me by the time I got into my car and tore down the road after her she had got held up at a set of traffic lights and so I was able to follow her at a distance without her knowing I was there. Strangely enough she wasn’t driving that fast, in fact she was driving quite well. I was somewhat relieved at that and so after a while I started to think of just letting her go and go back home to bed. I thought I would follow her just for a little while longer and if she carried on the way she was I would leave it. Just as I was coming round to the idea of turning round I noticed she had started to drive more slowly. Then, without any warning she pulled into the side of the road and just sat there. I pulled over and watched her to see what she was going to do next. After about four or five minutes she turned her lights off, got out of the car and started to slowly walk away from the car. Normally I wouldn’t have thought too much of this, but unknown to her we were in what I knew to be a prostitute area. It didn’t seem to dawn on her that the streets were dimly lit, but I knew the area well and if a car was driving around there at 12.30 at night it was only after one thing – a prostitute. There was no other reason to be there. To make things worse, being a very hot summer night, she only had on a short white top and a light silky skirt which tended to creep into the crack of her arse as she walked. The top only came part way down her torso so that there was a slice of flesh showing between her top and her skirt. She also had no tights on either. I sat watching her walk very slowly along the pavement and wondered if any cars would pull up and proposition her. That would frighten the daylights out of her and I could just see her shoot back to her car and tear off. On the other hand I really wanted her to be propositioned and to get fucked by a bloke in the back of his car, but no hope of that with her. It did not seem to be my night for a thrill though, because after about ten minutes of walking not one car came along. One did drive by, but certainly did not slow down or stop for her. Every now and then I would drive a bit further down the road to just keep her in sight because I would have loved to see a car trying it on with her. My guess is that being a bit naive she would talk to the bloke for a bit and then, when realising what he was after she would walk away quite quickly. But, nothing happened until suddenly I saw a car in my mirror and he was driving quite slowly. God, I hope this is it I thought. He drove slowly past me and I could see he was in his fifties or so and clearly looking. Slowly he drove along getting closer to my wife and then, yes, as he nearly got to her his brake lights came on. I immediately got a hard on and my heart was racing like made. He drove slowly level with her and at first she didn’t realise he was there, but he probably shouted out to her and she stopped and walked over to his car and bent down to the open window and started talking to him. They talked only for about 20 seconds or so and then she quickly stood bolt upright and I thought she was going to walk off. But he must have continued to talk to her because instead of shooting off, she started to talk back to him. She wasn’t bending down, just standing on the pavement talking back to him from there. They must have been talking for a good four or five minutes when suddenly his passenger door opened. She stood there for a while and then got into his car. I could not believe it. My wife in a car, late at night in a prostitute area with a stranger and being driven off to boot. She had to know what he was after. There was no way he had asked her the way. He must have propositioned her and so she had to know he wanted to fuck her. There was no other reason for him to talk to her. As they drove slowly off I started to follow as far back as I could with just my side lights on so he hopefully would not spot me. Fortunately they only drove a very short way when he turned off to the right into a dimly lit alleyway and stopped. I pulled in before the alleyway and got out of the car and raced as fast as I could to the edge of the alleyway to see what I could see. He had turned his engine off, but not his lights so I could see the outline of both of them. They were just sitting there talking. Just get on with it I thought, but no they just talked and after a good quarter of an hour I figured nothing was going to happen and I had a wasted night. I hadn’t even guessed anything would to be honest. I know her too well. On the other hand I couldn’t understand why she got into his car in the first place. It’s just not her. But she had and so maybe she thought if he wanted a fuck and she was furious with me, why not. But I didn’t really believe that either. And then to my utter amazement he leaned over to her and was obviously kissing her. She just sat there for a bit and then slowly I saw her turn more towards him while he continued to kiss her and her right arm came up around his neck. I nearly shot my load there and then. She was obviously kissing him back and liking it. They kissed for what seemed like ages and so I tried getting closer to the car to see if I could see more of what was going on. I managed to get right up to the back of the car and was delighted to see both their windows were open because of the hot night. I crept along the passenger side of the car as far as I dare and I could hear her moaning and could feel the car moving about. I figured he was fingering her and she was getting really worked up. The moaning got louder and I peeked over the top of the back window to see her wriggling about like a madman. He appeared to be moving his left arm around very fast and I reckoned she was about to cum. Sure enough within a second of thinking that she bucked like mad shaking all over the place and letting out a huge yell. She was obviously having an enormous orgasm. When she had finished her orgasm they both laid back in their seats and he was talking to her. I’m sure I heard him use the word fuck to her, but I definitely heard her say yes, alright. As I had a good idea what was going to happen next I got away from the car as quickly as I could and found a doorway that I could stand in being completely in the shadows only a few feet from their car. Just as I got there both car doors opened and they both got out and got into the back of the car, closing the doors quietly. I had a great view of what was happening. They had the back windows open as well and I could almost see right into the car through the passenger door open window. I could also hear them much better than I could before because I was actually much nearer to them. As soon as they were in the back he started to take his trousers and pants off and she pulled her skirt right up above her waist and took her knickers off. She also kicked her shoes off and then lay with her back to the door and her legs the length of the back seat. He then got on top of her, pulled her legs apart and slowly lay himself full length on top of her. They started to kiss again and this time she seemed to be more kissing him than him kissing her. She was getting very, very passionate and pulling his head onto her and moving her face around all over the place. Then I noticed his buttocks were moving about a bit and I realised he was getting the head of his cock against her clit ready to push in and start fucking my wife. And that is what happened. Slowly he started to get flatter and flatter onto her body as his cock started to enter her insides. He went further and further and further onto her until he was obviously completely inside my wife’s belly. She kissed him even more passionately and started to moan as his huge cock pushed hard and deep inside of her. He seemed to be pushing himself inside of her as hard as he possibly could. and with every bit of strength he muster. He wasn't fucking her, just pushing his cock inside her belly as far and as hard as he could do it. Then he started to fuck her. Slowly at first but then faster and faster and faster like he had never had such a gorgeous fuck in his life. He fucked her and fucked her with my wife grabbing hold of the cheeks of his arse and pulling him deeper and deeper inside herself. She wrapped both of her legs completely around his waist going up and down with him as fast as he was so that every time he slammed down very hard into her she pushed herself up as fast and as hard as she could to get his cock to ram inside her as hard and as far as it was humanly possible to do. She must have cum at least three times in five minutes. She just loved him fucking her the way he was. She was fucking him as much as he was fucking her. They fucked and fucked and fucked for what seemed like ages. But then I suddenly realised that at the speed they started to fuck after he had undressed he did not have a condom on. And he was obviously getting ready to pour his spunk deep inside my wife’s belly any minute now. I figured she must have known that, but still wanted his spunk inside her. Or did she? I’m not so sure because as he was fucking her faster and faster and more violently, I heard her say something about pulling out. But just as she had said that I heard him moaning like mad and ramming her much harder than he had up to now. She seemed to be pushing him away, but it was no use, he was totally out of control as he shot spurt after spurt after spurt of spunk very, very deep right inside her belly as fast and as hard as he could. He just seemed to keep on spurting this spunk forever. He was ramming her crazily fast as he shot and shot and shot until finally he just completely crashed down flat on top of her exhausted. They both just lay there for a moment without a word being spoken. Then I heard her say in quite a loud and furious voice “You PROMISED” me you would not cum inside me. I would never have allowed you to have sex with me if I had known what you were going to do”. They talked for a while and did not seem to get on too well at all. Then I saw her start to get dressed and shortly afterwards she got out of the car, slammed the door, walked right past me in the shadows and went out of the alleyway in the direction of her car. I decided to wait until he had driven off before I came out of the shadow of the doorway. I then got into my car and drove home as quickly as I could, got undressed, into bed and waited for my wife to come home. She did about only five minutes after I had got into bed. I pretended to be asleep and she went into the shower room and came out with nothing on having obviously dumped her spunk filled clothes in the laundry bin. I had a great evening.
