I was watching a group of attractive women getting their stuff out of their cars while I was parked near a beach in San Diego (Coronado actually). I was really going at it, thinking they couldn't see me from the angle I was at.

Right as I started to cum, I heard someone say something. I looked out the passenger window, and two women (different than the group I was watching) were watching me. At this point, I couldn't stop and kept cumming. The towel I had planned to use fell on the floor, and I squirted all over myself and the car. What a mess! I think they were standing there for a while. Still, I panicked and quickly started the car and drove off; they yelled something as I drove away. I was worried they would take down my license and call the cops, but nothing happened.
