Last month I picked my wife up in town after she had been out with some friends. She was very drunk and I noticed a bloke following her when she came out to meet me. My wife is 41-years old and has a small petite figure. She looks a lot younger than she is and often attracts younger men. When we were driving home I asked who this bloke was and she stated he had been chatting her up all night and at one point was rubbing her cock against her at the bar. This started to turn me on thinking a young bloke wanted to fuck my wife who was probably old enough to be his mother.On the way home I pulled into a local beauty spot car park and had her dress,bra and knickers off in seconds. A took her straight from behind and slid into her soaking wet pussy. I said, " Imagine that bloke was fucking you know instead of me". She got really turned on and within a minute or so of me repeating this over and over had an orgasm. This rarely happens between the two of us and it was apparent to me that she wanted this bloke to give her a good seeing to. We sat there after and discussed it and I said the next time she went out, she should fuck the bloke if it was just sex.We said nothing about this after that night and a couple of weeks later I picked up in town. Again she was drunk, I joked if she had a cock rubbed against her. To my amazement she stated that she had fucked a guy aged about 20 in the ladies toilet. She joked that he shot his load within about 2 minutes but this gave me a massive turn on and when we got home we had sex for hours.Now everytime we have sex I ask her how many guys want to fuck her and she shouts 'loads'
