My wife and i have been married 12 yrs and really lead a normal life. She is 5'5'' and 126 lbs, redhair and in really good shape. Our sex life is still great after 2 kids and she has a great kinky side. She works at a dress and undergarment store in our mall and has to dress to the nines while at work . 2 nights ago she told me due to inventory they would have to stay late so feed the kids and shed be home when they wrapped it up. Well we decided to eat out, so i went to a local fast food place and grabbed some burgers and got her one that i was going to be nice and drop off on my way back home. I drove to the back of the mall and only 2 cars were behind her store. As i walked up i could hear music so i rang the bell, and noone answered, so i rang again and still no answer. It was dark out and the office light was on. But it was about 8 ft high , and the dumpster was under it so i set the bag down and stood on the dumpster to look inside. I was in shock- my wife was onthe carpet,dress up around her waist and her boss, a tall black man, was pumping his big dick in and out of her pussy with her matching him by slamming her hips into every stroke. I never seen her fuck like that - it was like i was dteaming. A short time later he quickend his strokes, and she spread her legs as wide as she could, and i knew he was about to come- in my wife !!! Finally he stopped and slid his dick out, covered in come , it was huge. Long thick and a big head and stroked the last of his load onto her shaved pussy. I couldnt hear them because of the music,but when they were getting up i jumped down and drove home. I came in gave the kids there food and went to the upstairs bathroom, closed the door and pulled my dick out and pumped it so hard when i came i was weak in the knees. It turned me on so much i could not believe it.
