I have belonged to a camera club for about two years. I'm mostly interested in landscapes but have done the occasional portraits for friends. I am one of few women at the club and most people there seem to be a bit nerdy but it is useful to get tips and someone has a good contact to get equipment at cost price. As I am quite curvy. with large nipples, one of the older men was always trying to get me to do a photo session for him but I always refused. not really taking him seriously. I said I could never strip off in front of all those men. He suggested that I could do it just for him and it would be our secret. He suggested enough to pay for a new prime lens that I was interested in getting. I said that at my age of 45 I wouldn't really be what he is looking for anyway. He said that he wanted a natural woman, not a perfect model. I'm not sure if that was a compliment or not. Anyway over the weeks he continued to pester me at every opportunity, and said that the money would be enough to get that lens. I agreed on the understanding that nobody else knew about it and he agreed that he would come to my place on my day off the following week. Rick was a rather large fat man, quite short, balding and tended to wear joggers and tee shirts, so really not the most appealing.. I suspected he was after some quite candid shots but told him that I would be only be doing underwear. He turned up at my house and paid me my modelling fee and I waited his directions. I was new to this but he said that he occasionally had live models to photograph at his house. and he also hinted that he had a good time which I said he can forget with me. Anyway he took the usual bra and panties shots, trying to get me to open my legs further each time. I changed a couple of times into sexier underwear and I could see him sweating a little as he took some close shots. I noticed that he was hard under his joggers and it certainly looked as if he wasn't wearing underwear himself. I noticed him secretly rubbing himself a couple of times when he thought I wasn't looking. At one point I went to get changed and looked back through the gap in the door and he had taken his hard cock out and was rubbing it. It was a good size and quite thick. For some reason I suddenly had a wave of horniness come over me. It wasn't him, it was the situation. I came back wearing quite see through underwear and this time followed his instructions to open my legs further. As it was see through he could see everything under my pants and he got in close for some intimate shots. He reached up and pulled my bra straps down and my bra was hanging loose. He said to pull it down a little more until he could see the edge of my nipples. He got me to pull my pants up really tight and he could see everything I had. He then reached down and pulled my pants to one side which I was shocked by, but did not stop him. I could feel him glancing my pussy and felt the wetness as his fingers lingered. I wasn't sure why I was letting him but I was enjoying showing a dirty little man my body. I was asked to strip off completely but as I was reluctant he offered me more money as he was stepping outside of what we had agreed. I agreed and he could see that I was very wet and I was very turned on by showing him and my clitoris was sticking out as it is quite large. After that there was no pretence about accidentally touching me. He took every opportunity to grope me, and I actually let him. He was pulling my pussy apart to photo it and openly rubbed himself through his joggers. I was soaking wet and he rubbed my clit and I had my first orgasm. I couldn't believe that this short fat man was turning me on. Within a few seconds he was naked and his fat belly hung over his stiff cock. I was laid back on the sofa and he just got on top of me and stuck his cock in me. It was a job getting it in with his belly in the way but he got it into me and came within 5 seconds. I was not expecting him to be quite so quick so pushed him off and rubbed myself until I came on my fingers. He quickly got dressed and left saying how much he had enjoyed himself. This is obviously a fantasy but the first part is true. I do have a short, fat man at the club who wants to photograph me, and I have sort of agreed to do it. The more I have thought about this, the more turned on I am getting and if it does turn out like I imagined then I will let him touch me and maybe go further. I have already planned my underwear and have actually chosen the most see through set. I suppose I wrote it down to see if I'd actually think about actually going though with it.
