Pulled into a parking spot by a mall in Swansea, MA. The wife wanted to run in and get something. I hate shopping so I stayed in the car. I noticed a car pull in and the young man got out and walked over to the window and talked to another guy. The walkup guy got into the car. I was about 15 feet away. Their car was facing me. There was something going on by the look on the drivers face. I could see him slide his seat back. Passenger was busy with his hands in the drivers lap. After a little bit the passengers head went down between the drivers legs. I could see his head bobbing up and down. I could not help but get hard. I was rubbing on mine while the guy in front of me was getting a great blow job. After a while I could see the passenger lift his head and he had cum dripping from his mouth. He looked over at me a swallowed and licked his lips and smiled. I gave him a thumbs up for a good show. Just then the wife came up to the door and got in. I was grinning and she asked why. I told her something was funny on the radio.
