My Wife's Business Trips

We have been happily married for over 20 years, and raised two of our own children, so I was surprised to discover my wife has been cheating on me. We have a great sex life, in fact our sex life improved greatly with her new job. She goes on lots of business trips with her new job, and one day when I was helping her pack, I found she had one of her sexy negligees, several thongs and a tube of KY jelly packed in a side pocket of her suitcase. I was stunned because that is what we use during our heavy sex sessions at home! She must be fucking her co-worker on these business trips! The thought of it turns me on, so I did not say anything.
When she returned from her trip, I made sure to check out her luggage in secret. All of the thongs and panties in the suitcase were stained and reeked of cum! The tube of KY jelly was almost empty! I got so hard that I had to jerk off into her cum soaked panties myself, and then put it all back. My wife is a hot wife and it turns me on!
I found out, after much questioning and prodding, that she travels with a young male co-worker that is also married. I met him at her office one day, and discovered he a is very big and muscular young man. No doubt he has a very large cock that my wife could not resist.
Our sex life has been great, and I fuck her harder now knowing that she is fucking a big man at the office. It may be sloppy seconds, but it turns me on to mix my cum with his deep inside of her!
