I was looking out the window on the M15 bus yesterday, and I totally saw a guy jerking off in his car.  There was no one else in the car, the guy was actually driving with one hand and furiously stroaking his dick with the other.  Every time the bus stropped at a light, the car seemed to pull up next to us, and there would be the driver, spankin' it in broad day light, in traffic.  This guy jerked off from 86th street all the way down 14th street.  He might have kept going, but I got off at 14th, so I never got to find out if he came or not.  I tried to take a picture of him, but the bus window was really foggy, and I couldn't capture the situation clearly.
