Two years ago my sister Theresa talked the other three girls into letting the guys fuck them along with her two nights each week. There were twenty of...us and four of them so it actually worked out perfectly and we each got to fuck them twice before they had to return to their side of the lake. The guys were shocked the first time that they saw me fuck my own sister.Theresa saw the looks on their faces and said, “Get over it! It’s not the first time he has fucked me! We’ve been doing this ever. I should have joined the conversation, but my mouth was too full. Eric was getting very excited now. I could feel him pulse and twitch, and occasionally he would push so deep that his cock filled my throat and gagged me. Now I was getting excited - very close to the edge of a massive orgasm. Sensing that, Eric withdrew himself and slid off the bed. I could feel sweat on my brow, and my breathing was quick and shallow. I held her hips and pumped into her with renewed vigour, while Eric grinned. He had brown wavy hair cut conservatively, a shy smile, but piercing eyes that seemed to know what I did at the sauna last weekend, and with whom. He was pretty young, 26, but sharp. As the week wound down there were three reports that everyone at my work forgot to complete, so of course it landed on my desk. I looked at him and thought—I have seen this guy’s face somewhere, but I don’t know where. I had all of my regular tasks to do when I looked up at Mark exasperated – in his Friday. I hurried up to her bedroom and caught my breath after all this time I had made it in to her bedroom though on my own. I looked in the first drawer but it was not it, then the second then the third and there they were. All laid out neatly mainly white brassierres, knickers, and tights all on top. Carefullly and remembering how they were, I lifted out the top ones to see what lay beneath. As I progressed I found a white suspender belt and then a cream one, realy good ones, deep panelled with.
