I have a very complex situation that led me to the point where I am very technically a cuckold but it was unplanned and accidental from a one time experience. A few years ago my wife and I had a night away for a wedding where we got to stay in a hotel out of town and had an opportunity to have fun. We had lots of drinks and fun at the receptions and then continued at the after party. Neither of us remembers much from the after party but we do know that we somehow ended up with another guy in our room for a threesome. We had never been part of that lifestyle and it was our first and only threesome. There was a lot of sex that happened. A few weeks after is when we found out she was pregnant. We both thought about that night immediately but then figured it was unlikely since we had been trying for a while for our second. It’s something that now I think about because when I do the timing it is highly likely it was that week that she got pregnant and most of our sex happened that night. And if it was that night then the other guy had a much higher likelihood of being the one who knocked her up. It’s something that my wife seems to just completely ignore as not a possibility but it is something that will enter my mind a lot. Nothing like that has ever happened again and I’m not sure she would want it to. Not something I have told anyone I know for obvious reasons and not something I can discuss with her.
