Back when I was 15 in the 70s Volkswagen beetles were a popular girls car and miniskirts were all the rage. Being 15 with no real knowledge of sex I found seeing girls sitting in a VW very arousing the sight of bare legs on the vinyl seats was exciting and I would get a massive hard on with out knowing how to release the tension it just built. I got a weekend pocket money job in a worksop that specilised in Volkswagens and regularly saw hot girls sitting on the seats getting in or out of their cars which was a bonus. One hot saturday the boss went away early leaving me to sweep and lock up. As i was sweeping a 63 beetle pulled up with 3 really sexy girls in it in their late teen early twenties. The driver Whos name was Louise came over and said that her battery needed replacing. I said that the boss was not here but I knew how to replace a battery as i had seen it done. Ok she said where do you want me to put the car. I said just drive it in here. she pulled up got out her friends remained in the car the girl in the front passenger seat was stuunnig long red hair really short skirt sitting on the green and grey vinyl seat. Iwas starting to get aa hard on my cock was 7 inches long and i was wearing shorts that were to small as i had taken of my coveralls earlier to go home. T said to the girls that they would have to get out of the car so I could replace the battery which was under the back seat. They both got out and stood over the other side watching what i was doing. I was very aroused at the thought of taking the back seat out with them watching so i thought about taking the front seat out too where the hot redhead had sat. I started with the front passenger seat lifting the lever to slide it forward so I could un hook the spring under the seat and slide it out. The seat had not been out or moved much and tok a lot of wriggling yo start it moving. i was getting a strong aroma of vinyl and pussy coming of the seat which was making me as horny as hell. The red head called out and asked what I was doing with the front seat and i said I was going to take it out. Can we see she said. Idid not answer as by this time the fact that girls were watching and the smell of the seat waas to much and my cock had worked its way out ant was down the side of my leg and did not want them to see. The seat was almost out I had unhooked the spring and was about to stand up slide it of the tracks and lift it out when one of the girls opened the driver door to see the seat come out. I tied to cover my hard on with the seat but it caught my cock which sprang full out and was now rubbing on the seat. The girl looked shocked to see my prick on her seat. The friction of the seat caused a massive ejaculation which covered the driver seat as well as the one I was removing
