Driving home, I had received a phone call.
I pulled into an industrial site to answer, when I got to the phone it was too late. I thought I would take a minute to re contact the missed call when I see a car in the distance that caught my eye. As I drove closer I noticed a man sitting very still and with a nervous aura about him.
I don't know why but I parked the car up and watched this strange man for a minute. I noticed he was making movement with his hand, I couldn't work out what he was doing until I got out of the car and decided to approach him.
As I walked closer he was still moving his hands, only when I got to within a few meters did I realise he had his cock in his hand and was slowly stroking himself.
Shocked I turned away and started quickly walking back to my car. As I was walking away I couldn't work out whether I was scared or somehow turned on by this. Once back in the car i sat for a minute and caught my breath, only to realise the bulge in my trousers.
