I could easily feel Kathy’s right breast pressing against my upper arm, I turned my head slightly to look at her, she smiled up at me and pressed her lips on mine, I looked up and saw that Paul was still watching us in the mirror. Kathy took my hand and placed it on her left breast and whispered that her dress opened at the front. I undid a few of the buttons and slipped my hand inside. I discovered that she was not wearing a bra and my fingers found her nips. She gave a low moan and kissed me again but this time slipped her tongue into my mouth.

Kathy’s hand was stroking my thigh and getting closer to the bulge that my cock was making in my tight jeans. It took her a few minutes to undo my belt and pull my zip down but only a few more seconds to reach inside and wrap her fingers around my hard cock and pull it free of my underpants. She lifted her head from my shoulder and moved away from me a little. She undid a few more buttons on her dress and pulled it open so that both of her breasts were exposed. They were not very large but her pink nips were as hard as peanuts.

She asked me if I had ever fucked a girl on the back seat of a moving car, when I said no she laughed asked if I would like to. I said of course I would but what about Paul. She leant towards Paul and asked him if it was OK for us to fuck. He just said “Go for it girl”.

She moved back into the seat and lifted her hips and pulled the hem of her skirt up to her waist. She had a small pair of white knickers underneath and suggested that I might like to pull them down for her. I did and put them on the seat next to her. I ran the palm of my hand over the tuft of dark hair between her legs and slid my fingers along the damp slit below. Kathy lay on her back diagonally along the seat and pulled me over onto her. I was getting my feet tangled in my jeans and underpants so she advised to to kick them off completely. I got between her legs and she used her hand to guide my cock into her fanny. As I started to move into her she began to give a running commentary to Paul. “Jake’s got his cock inside me now and it feels good”.

It might not have been the most comfortable sex that I had had but it was certainly the most exciting, in fact it was too exciting and I soon passed the point on no return and emptied my balls into her. I think that Kathy was disappointed with my performance, because as I pulled out of her and moved away she took my hand and showed me how to move my fingers in little circles over her clitoris. Soon she was telling Paul that she was having a cum and my fingers were soaked with her juices. She used her knickers to dry herself then handed them to Paul who sniffed them before giving them back to her.

Paul told her that his own cock was as stiff as a poker listening to us fucking and asked Kathy what could she do about it. She told him to stop at the next services and she would sort him out. He said that there was one coming up in about ten minutes. Kathy cuddled up to me again the two of us still almost totally naked,

I asked Kathy if they made a habit of seducing young hitch hikers, she said that actually I was only the second, the first had been a few weeks earlier but he was very shy and nervous and he had ejaculated almost immediately she had touched his cock he then wanted to be let out of the car as quickly as possible.

We arrived at the services and Paul parked the car in a quiet dark area of the large car park. Kathy closed the front of her dress and pulled her skirt down. She got out of the car and got into the front. Paul reclined his seat undid his trousers and pulled his impressive cock out. Kathy lowered her head onto his lap and I was able to watch as she expertly gave him a blowjob. After moving her mouth up and down on his cock for five or six minutes he held her head tightly with both hands until he gave several sharp jerks then gave a loud sigh and said “ You’re the best “.

I expected Kathy to remain sitting in from but she came back next to me again.

Paul rejoined the motorway and said that he expected to reach Durham in about an hour and a half. Kathy asked me if any of my girlfriends had ever given me a blowjob. I said that a couple had but never as skilled as the one that I had just witnessed. She could see that my cock was erect and said that she could’nt leave me in that condition. Her mouth and tongue was soon working it’s magic on my cock and she took me to the edge several times before allowing me to shoot my semen into her throat.

For the remainder of the journey we sat talking with occasional touching of each other’s bodies. At one point Paul said that we had enough time to fuck again if we wanted but I said that I had already been drained. I did however manage to bring Kathy off using my fingers on her fanny and my mouth on her nips just before we got into Durham.

The dropped me off outside my flat and they said the might see me again standing by the road with my thumb out, but I never saw them again but it was a still great erotic memory.
