We lived in some apartments and had an older lady for a neighbor. D. liked to work on cars and one day as it was heading towards evening she was out under the hood of our neighbors car.
I should mention what she was wearing. An outfit that buttoned down the front with VERY short legs. Short enough her ass cheeks showed.
So she's there with her hear and arms in the engine compartment and I come up quietly behind her and start finger fucking her. She's stuck with her head in the engine compartment moaning like crazy. I kept it up for a couple of minutes then walked away and let her get back to the engine. I did this a couple of more time, finger fucking her then walking away. The next time I walked up she was expecting my fingers again.I had my cock out and rammed it in as hard as I could. Oh damn that's not your fingers she moaned. That's right I said banging her as hard as I could in the parking lot where anybody could have come along and see. She started cumming almost immediately while I took my time. She was about ready to collapse by the time I came. She didn't do any more work on the car that night.
