My gf asked me to go test drive used cars for her son at this small car lot. She thought two hot women would get a little better deal than one lol. Well of course once we got onto the lot we were surrounded by salesmen. You could tell they all wanted the deal but one of the older ones pulled rank and made the rest go away. He was showing us a couple cars that he said were a good deal and would be great for a first car. She and he decided that they would test drive two cars an older Toyota and a Ford. So I jumped in the back seat and they get in front. After they drove the first one around they started talking prices clearly not wanting to pay the full price she was trying anything she could to get him to lower it. That's when it changed. He did say half joking that there was a way for him to knock off a few hundred dollars if we showed him something worth it. Of course this is why she bought me lol I figured it out. Well from the back seat I got his attention and flashed him my breasts. Shocked he didn't know what to say but clearly enjoyed the view. We made our way back to try and test drive the other car. I jumped in the back seat again letting then get in the front. As I settled in I noticed he got in the back seat with me. We drove off and about that time we left the car lot he said there was a lot more wiggle room in the price of this car, but we would have to work it out. I glanced up at my friend and I could tell she wanted me to help out. So I went for it. I leaned in and pulled his pants down, I took him in my mouth and began sucking. His cock was decent sized nothing too special. He was an older guy so had white trimmed hairs all around. I continued sucking him until he was completely hard as my friend drove us around (hopefully not populated areas). Once I could tell he was on the edge I stopped and had already decided I wanted to do more to get the most off in the price as possible. So I slide my panties off from under my skirt and straddled him in the back seat. Positioned him and slowly slide down his cock. My friend hit a bumb right as I was on him to force him into me. I began riding him in the back seat now I could see we were driving through a neighborhood but none of that mattered now I had one job. Doing my best I grind on his cock feeling him swell in me. Luckily I was able to orgasm letting my juices run down him as he came deep in me. He was spent, so I got off him sat bare on the car seat undoubtedly leaking him cum onto the cloth seat. We made it back to the dealership and they drew up paperwork for the car and she was given a great discount barely had to pay anything for the car. I keep joking with her, she and her son owe me big time for the car!
