One night my wife was giving me a blowjob while we sat in our car in the parking lot of a rest area. She had removed her top and bra exposing her lovely 38DD tits. My jeans were down around my ankles and my stiff cock was warmly enveloped in her sucking mouth. I was rock hard and she had been slowly sucking on me for about ten minutes.
A car pulled into the space next to us and a man got out and walked past our windshield on his way to the restrooms. I watched him walk by and enter the restroom and I watched him walk back. My wife never lost a stroke and when he got to where he could see into our car his face lit up and he slowed down. When we didn't stop what we were doing, he came alongside my driver's window and stared at her gobbling my cock with her big tits hanging. She stopped long enough to look up at him with her spit and slobber dripping from her chin then returned to sucking on my cock.
He began rubbing his cock through his jeans while watching and before long; he had hauled his cock out into the open and began pulling on it. Swelling to its full size as he jerked on it, the end of it began oozing pre-cum as he watched my wife deep throating my cock.
She was looking up at his cock as she sucked on mine, so I decided to grab his cock and jerk it for him. It was hard, thick, and long and he didn't object when I took it firmly in my hand and began to jerk it. My wife began sucking even harder and faster as I jerked. His eyes were glazing over from pleasure. She quit sucking my dick and jerked on it instead. That seemed to do it for the stranger.
Without warning his big dick began shooting long ropes of cum through the window and onto my bare chest. My wife quickly ran her hands through his cum and used it on my rock hard cock. He was still shooting his hot cum all over me and my wife when I sprayed my hot, creamy cum all over my chest and the action of my wife's jerking even made some if it go through the window and land on him and his cock, which I was still slowly massaging. She eagerly began slurping it up from my chest and cock.
His cock began to harden in my hand again as he watched her clean my jizz from my dick, so I had my wife sit on my cock and jerk him off through the window. She grabbed his cock and within five minutes she had him shooting another volley of big ropes of cream.
