My wife was a state "Miss" back in the mid-70's, and those types almost always maintain their beauty throughout their life, and my wife is no exception.I was introduced to her by my sister that was three years younger than me while we were at the same college. We really hit it off very quickly. For w few months I tried and tried to get in her pants, but all I got was some feels. She finally told me that she was a virgin. After a couple of more months of dating though, we finally had sex, and she loved it! I had graduated and she was still had just started her senior year when we married. She finished college and we had a great sex life. I never felt like I was missing something and she never seemed like she was either. After about 15 years of marriage and a couple of kids, she was still stunning in her mid-30's. We had talked about getting a boat again (we had one before we had kids), and a friend suggested a Pontoon boat so the kids could have lots of room, so we got one. We kept it at a private dock on a pretty big lake. Every now and then we would leave the kids with one of our parents house and go boating alone, and we always managed to fuck our brains out those times. The lake has lots and lots of places to pull up into that were secluded but we had to be careful because at some of those places people had some nice cabins here and there. One day we were by ourselves and the usual urge to fuck hit us. We pulled well back into a secluded cove and started at us. If you are familiar with pontoon boats, you'll know that they typically have a swinging door at the front center that goes onto a deck. I had tied the boat off and left the door open, eager to get some action going. I had already licked that pussy and made her cum and was on top of her fucking her. All of a sudden she blurted out that she thought she saw somebody behind the trees about 50 feet from us. i looked around and saw nothing, but then the thought hit me, "lets see how far we can take this". I rolled over and put her on top and started fucking her again. Then I saw him, a young guy trying to hide behind a tree, and he had his cock out stroking it. I just sort of motioned him closer with my finger so my wife couldn't see me. As he moved closer I saw that he was about 19-20 and has a college shirt on. He was about the same size cock as me. when he was about 10 feet from the boat I turned my wife around in one of those reverse cowgirl positions. the guy moved behind a tree, but I motioned him out a little so when my wife opened her eyes she could see him. A couple of seconds later she did so. She stopped and told me that he was close to the boat and asked what we should do. I just replied "let's give him a show", and motioned him closer. He went ahead and stepped up on the boat and I motioned him closer, My wife was so wet I thought she was going to drown my cock. As he moved closer I saw that he was uncut - my wife had asked me a couple of times over the years what that looked like. Well she got a chance to see. I just sort of nodded to him to move closer and told my wife to go ahead and touch it, and she did. She had hold of him with both hands and staring at that cock. I said my back was getting carpet burns and moved up on to a seat and she got right back on me in the same reverse cowgirl position, but she let go of his cock. I wanted to see that cock of his fucking her, so I told him to get down on his knees. All the while he was back at stroking his cock as my wife watched him. I motioned him in closer and closer till the tip of his cock was against her pussy. I was twisted around watching everything happen in front of me. I pushed her up and off of my cock and watched him slide his cock up and down her dripping slit. Finally when he got to that sweet opening he placed the head of his dick and pushed a bit. She met that push with a harder push and after about three strokes he was all the way in, pumping away. After about then more strokes I felt her tense up as she started to cum she relaxed a bit and he started to moan a bit, so she pushed him back so hi cock came out and she stoked him until he shot a load all over her stomach. She grabbed a towel, wiped that off and said to me, lets show him how you fuck me. After only a minute or so she stared to cum, and that just made me cum too. After that she just said to him "now you have something to tell your college buddies about in the fall. We never talked about it again though after that day for about 15 more years, nor did anybody else fuck her, of course, that i knew of.
