A stranger caught me masturbating in a car and offered to help

Filmed on a phone, the quality is amateurish, but everything is clearly visible. I was sitting in the car in the parking lot, I thought there was no one there, I relaxed and started masturbating right in the seat. I didn’t notice how a man parked nearby and saw everything through the window. I knocked and I didn’t leave, but rolled down the window. Then he sat down next to me, and I took his penis into my mouth right in the salon - it was cramped, uncomfortable, the camera was shaking, but everything was filmed close-up. Then we went outside the car, he fucked me from behind, holding onto the roof. Home filming, no editing, live sound - you can hear everything. In the finale, he cums on my back and they both laugh at the camera.
