My then girl friend and I worked back at an engineering works that we worked at. She would come down to the shed when It was close to seven and get me and we would lock up. This day I was enjoying a few beers on a Friday when she came down shaking that arse of hers I noticed a couple of extra buttons undone on her top she came over to where I was and leaned back against a bench arching her back showing of her large d cup tits which looked good in the white silk top she had on I could easily make out her dark nipples under her lace bra. I said if she continued I would fuck her then and there in full view of the neighbours and onyone passing by. You wouldn't dare he said this as all a needed as encouragment and stepped up to her, she quickly put her hands up to stop me touching her. Don't you dare touch my top, ok then your going to have to strip for me. She slid up onto the bench and started swinging to a metallica song on the radio whilst slinding her skirt down and beding over for me showing me her matching lace g-string then she turned and took her top off real slow one button at a time. I reached up to grab her and she slapped my hands away not yet lover. I was glad I had't turned the shed lights on which sould have given us away. She then kneeled on the bench and slid her g-string down I moved up and started licking that hot wet pussy only stopping when she shuddered in orgamism. This was to much for me I pulled her to the edge of the bench dropped my pants and slammed into her over and over harder and faster till I shot my hot load deep into her. As we started to move I noticed my boss under the eve on the side of shed putting his dick away. this was the first of many times I banged her around the shed and not the only time I saw that dirty old fart watching I'm sure my girl got off on it.
