After many years of fantasising about having sex with a man who's very well endowed, I got the very real chance at a wedding reception myself and my husband were attending. The whole event was spread over two large marquee tents and the ground floor of a golf club, clubhouse. I'd drunk more than I sholud have and seeing my husband talking about golf again to a friend and neighbour of ours, the clubs captain, I wandered off to get myself another drink. Thinking I'd take a short cut at the rear of the club, I came across the neighbours son who was also attending the function. He was outside and he was smoking Cannabis. We both must have looked shocked to see one another, but somehow I must have looked worse because he said "Don't worry I aint gonna jump you mrs .....". As soon as he said it, my thoughts went to a conversation I'd heard my daughter having with a friend of hers, over the phone only a month earlier. She was explaining to her friend how she'd heard in college that our neighbour Jay has got a massive cock. At the time I put it down to cock envy and girls just being girls. Stood outside the golf club in the growing darkness, I put my marriage, morals and my virtues to one side and pretty much blackmailed Jay into having sex. Telling him I wouldn't let on about his Pot smoking to his dad, if. Near the sheds housing the machinery for the golf course I lifted my skirt and took off my knickers. At the same time jay was undoing his trousers and you could probably have heard my gasp from the golf club, as Jays huge cock sprung forth. Even in the gloom I could see my daughter and her friend were right about Jay, his cock was the biggest certainly I'd ever seen. I now know it to be just over ten inches in legth and it's so amazingly thick. I did try to suck it, but it was too thick to really get into my mouth, so with a growing urgency on both our parts I leant up against a tree and offered my pussy to Jay from the rear. It was and is the best, more awsomely dirty fuck I've had the total pleasure of receiving. It was slightly painful at first, but even that was something of a pleasurable episode. When Jay finally thrust his hips fully forwards, and litterally impaled me on his mamoth manhood, I couln't get enough of his superb cock slamming into me. I'd cum within seconds of him filling me and carried on cumming as he built up his speed and rhythm. The whole sexual encounter only lasted around fifteen minutes, but it was enough for me to cum at least four times, and for Jay to completely fill me with his boyish enthusiasm, flooding my pussy with his hot sticky cum. I walked with difficulty back into the function with no one any the wiser, but also knowing I'd cheated on my husband for the first time. It was as I keep telling myself, a one off, an aboration of who I normally am. I also keep telling myself the fantasy has been fulfilled and I don't need to go there again. But, each time I see Jay now, and I do almost daily, I have to admit, I'd allow him and his massive cock to fuck me again in a heartbeat.
