Was driving home tonight, about 8 45pm and as usual I was driving without pants and rubbing my cock. The road was nearly deserted and i was nearly home when I was stopped by the red light near the local shopping center, waiting for the lights to change i continued beating my cock thinking about spilling a load before getting home. Before the lights changed another vehicle pulled up alongside and the female passenger looked right down at my hand on my cock. I presumed she would be disgusted and look away but she continued staring and I got seriously hard. The lights changed and I indicated to turn off into the shopping car park so I could empty my load. I pulled into a parking bay and got to work stroking my cock when I noticed headlights pulling up next to me, it was the same vehicle from the traffic lights and the passenger was leaning out of her window to get a good view, so I took the opportunity to open my door and jerk off while facing her. It didn't take long for me to spill my load onto the tarmac while she happily watched and gave the driver a running commentary of my jerking technique. After spilling my load she said merry Christmas and they proceeded to leave, i closed my door and drove home, still hard at the memory of what had just happened and posted it here.
