I was intrigued with what the surprise was, after all I had only met Claire just under an hour ago. We soon arrived at our house and Claire said that she wanted to see the car first and sort all the relevant details out then I could have my surprise, which at that point I received the cheekiest grins I have ever seen. She was really pleased with the car and you guessed, yes I did agree to reduce the price slightly. All sorted Claire then asked if she could shower and wanted me to join her. It would have been rude to say no, so we went upstairs into the main bathroom and stripped off. Inside the shower she teased me and played with my cock till he was so hard again. I so wanted to fuck her in the shower, but she wanted me to wait. We got out and dried ourselves, then she asked where I liked fucking my wife. I said that we mainly fucked in the bedroom. She whispered in my ear that she wanted me to fuck her in our bed so that next time I fucked my wife I would think of her young body and what we had been up to. This really turned me on and we were soon on our bed, my fingers deep inside her wet pussy as she started to suck my cock. I so wanted to fuck her, but she wouldn't let me at that stage, saying it would ruin her surprise. Then she told me she wanted me to take some naked, naughty photos of her and some of me fucking her. She also wanted me to fuck her on the bonnet of the car so that I would remember selling it to her. Wow! she was a total nymph. She passed me her phone and I soon started to take photos as she posed in some very sexy positions. My favourite has to be of her lay spread-eagled on the bed playing with her tits and pussy..... what a picture. All the time I was taking pictures she would suck and touch my cock. She then led me out to the car she had just purchased and stood in front of the bonnet and lay back saying "fuck me". I was so horny by now and rammed my cock deep inside her soaking wet pussy. God it felt good. She talked dirty to me saying that if I ever saw her again I could rip her knickers off her and fuck her wherever I chose. She said she loved me fucking her and when she got home she would play with her vibrator thinking of me fucking her. She was such a horny, randy young girl and a body to die for, as I type this now I have such a hard-on and I do this as my wife is in the garden sun-bathing, if only she knew! The time that I didn't want to come had arrived I had to say goodbye. It was approaching 6pm and my wife was due back. There is no way she could find me fucking a girl half her age. We showered again and got dressed. Claire then got into what was now her car and passed me her phone again. "take a picture when I say" She then undid her dress revealing her beautiful body and told me to take a few photos. I took a few photos through the windscreen, side window and then opened her door and took some very close up pics. I handed the phone to her and she said that she would send a few to me so that I didn't ever forget her, how could I? She then undid my trousers, took my cock out and started to suck for dear life until I came and she swallowed most of it with some dripping onto her gorgeous tits. She then said she was going to drive all the way to the village with her dress undone and wanted me to go inside and wank myself off and take a picture and text her and if I did she would send me naughty pictures every week for the next year to me. As her car sped off down the lane I couldn't believe what had happened that afternoon. My wife came back that evening and asked "did everything go okay with the car sale/collection with that old lady we had sold it to?. I replied that she had gone away completely satisfied and loved the car and really appreciated me picking her up from the station as she wasn't that steady on her feet!.
