When I was 17 I had just passed my driving test and was desperate to get on the road but my parents didn't have the money to help me buy a car. I had a part time job but, having paid for my lessons, saving up was slow going. I was moaning to a friend of mine who was really into his cars and he said he would love to show off his car with a model draped over it like in Max Power or his other car magazines. I told him he couldn't afford a proper model and that's when he asked me to do it. He said he wanted sexy but I didn't have to do anything I wasn't comfortable with so I said ok. We went to his Dad's workshop (my friend was a trainee mechanic) on a Sunday when they were closed and I changed into a skintight outfit that had been bought for me. I have quite big boobs (34D) but they looked huge in this outfit and the bottoms barely covered anything. He took pictures with his crappy little camera and after about 15 minutes I said he had got his £50s worth. He then pulled out a wad of cash and asked how much for topless. I said another £200 thinking he would never go for it but he peeled it off, put it on the side and said 'well??' I pulled my top off - a deal's a deal - and he started snapping again. After a while I put my thumbs in the side of the skimpy bottoms and said 'another £200 and they come off'. He couldn't get to the cash quick enough and I dropped them. He took a couple of pictures but mostly stared then pulled his dick out. He was rock hard and asked if he could cum on me for another £50, I said make it a hundred and I would stroke it for him. He agreed so I stroked his dick until he shot his load all over my tits. I took the cash and it went a long way to getting my first car!
