One day after work, my affair partner and I decided to meet at a grocery store parking lot for a quickie. It had become a regular spot for us so we felt comfortable there. Since we had already done this several times we got pretty good about getting into a routine for these type of meets. We both stripped everything below the waist immediately and I assumed the position for him to fuck me from behind in the backseat of his truck. A couple of minutes into it and I received a message from my husband stating he was going to the grocery store and was asking if I needed anything. This is the same grocery store we were parked at just a few hundred yards away. My initial thought was sheer panic that he would see my car parked in the back of the lot. What I wasn’t prepared for was the intense thrilling sensation that came next. Knowing my husband was within a few hundred feet of me while I was getting fucked by another man in the back of a truck sent me into a whirlwind of pleasure. It must have been the same for my partner because he quickened his pace and within seconds filled me with his cum.
