Wife blow a guest at our new year’s eve party

Hi everyone,

First of all, I'm not a native, so please forgive any mistake I could make.

I really need to write down what happened a few days ago, but for obvious reasons, I don't wan't to take any risk to be recognized, so I will only use this throw away account.

A few words of introduction first. My wife and I are both in our mid 30's. We've been happily married for 8 years now. Sex is good, even though it has been 100% vanilla for a few years now. Strangely, it has not always been like this. Back in the days, we used to do nastier stuffs, like fucking outdoors. I even remember her giving me a blow job at a bus stop. I don't really know why we stopped doing this. I think that my wife wanted to test her limits then, or just to please me, and that she decided that she wasn't into that kind of stuff. It kinda bother me since I always have been aroused by the idea of being seen, or more recently, of sharing my wife.
