Jerk Off In The Back Yard

I had a job checking gas meters and I go around the neighborhoods every three months. I go to this one house, the meter is in the back and I walk past a window and a guy's on the bed jerking off. I hide and watch and I can see that he's watching a video. I get my hand going and jerk off to him jerking off and leave my spot on the wall.

That's it. Nothing much really.
