I work at our local university as a psych lecturer every now and again.
I was walking thru the car park late this afternoon when I noticed a cute tradesman in the front of his van, he was obviously masturbating to whatever was on his phone screen. Watching him jerk off in public got me excited. I felt my panties gettting damp. I was wearing a summery dress low cut the skirt finishes just above the knee. He didn't notice me staring so I walked closer he looked up at me and as he did I pulled one of my tits out and blew him a kiss.
What a rush! He sat there mouth a gape and watched as I walked past. I was so wet by now my panties were soaked so I snuck behind a bush whipped them off and put them in my hand bag.
I walked up behind his van and could see him watching porn and jerking off. He didnt see me until I was at his drivers door. Without a word I opened the door and put my mouth around his cock. After about a minute I could tell he was close and so was I. I knew if his cock so much as touched my dripping c**t id cum all over it.I whispered let fuck quickly into his ear. He took me from behind against his van with the drivers door open for a bit of privacy and my skirt of my dress up around my waist. as I suspected I came almost instantly. Only seconds later he pulled out and sprayed cum on the inside of my dress and my ass. I turned around held his cock in my hand and passionately kissed him goodbye. Only then I noticed the wedding ring on his finger. Hopefully I didn't kill his marriage.
I walked away feeling his cum on my base ass and the inside of my dress. It was probably the shortest but hottest sex of my life.
