It still amazes me when I look back on how I became an "accidental" cuckold. Unlike many men who write stories for Literotica, I have never had any desire to watch my wife with another man.
It all started when my wife and I rented a cabin with another couple, John and Susan. We had been good friends for several years, but there were never any indications that John wanted to sleep with my wife. She was a virgin when we married and I don't think she's ever even seen another mans dick. My wife Jean is very pretty. At 5'6" tall and 120 lbs she turns a lot of heads. She has a set of eye popping 36C breasts and legs that go on forever. John's wife is also very good looking with a nice tight ass and dancer's legs. Jean and Susan looked enough alike that they could have been sisters. The main difference is that unlike Jean, Susan has very small, petite breasts.
We arrived at the lake in the early afternoon and after quickly unloading the car, we got down to the business at hand - drinking and laying out in the sun. I must admit that after several hours of lying in the sun drinking, I was admiring Jean and Susan's skimpy bikini's out of the corner of my eye. We finally all went into the living room and watched a movie. After several more drinks Jean and Susan were very drunk and stumbled off to their rooms while John and I caught a skin flick on one of the cabin's cable channels.
After the movie was over, John and I were both sporting hardons. Although I could only see the outline, I couldn't help but admire John's cock. It looked to be at least 7" long. Unfortunately I was not blessed with a large cock. Mine was 4" long at best. John rubbed his dick through his bathing suit and went into his and Susan's room with the promise that he was going to get some tonight.
As I sat there imagining John and Susan having sex , I decided to walk over to their door to see if I could hear anything. When I got to the door, I could hear a whispering and rustling of covers and cloths. I was getting really hot listening and since there was no moon and the cabin was pitch black, I pulled my bathing suit aside and started stroking my dick.
I heard some moaning and a deep throated laughter of a woman getting excited and when she whispered "Bob, do me good" I had to laugh. My name is Bob and apparently Susan was calling out my name while having sex with her husband. I listened for a little more and continued to pound my cock. When she said "I've never felt so full", I started to get an uneasy feeling in the back of my mind. As drunk and horny as I was, there was a troubling feeling in the back of my mind. By this time he was really fucking her hard and making a lot of noise. I was jerking off for all I was worth when suddenly the door next to theirs opened up and a light went on.
