Wifes Awkward Work Week

Once a year my wifes company has a party. It is an "employee appreciation" banquet. My wife is a VP and oversees a unit of the company with a few government contracts.
Anyway the party was a week ago. The company has a few offices in the state. A lot of the employees drive quite a distance so many stay in local hotels for the night. After the party a group usually goes out and hits a bar or two. Me and the wife joined in as well.
I guess there were maybe 12 to 15 employees at the bar mingling, dancing and drinking. I won't give the exact age, lets just say my wife is in her upper 40's. During our time at the bar a very young guy, I am guessing maybe 25, was clinging to us like a spider monkey. My wife said he was a fairly new employee and hadn't been out of training long. I got tired of mingling and standing at the bar so I got a booth with a table. The wife kept hanging out with the employees. The young guy got her out on the dance floor a couple of times. I noticed that on the dance floor and while standing at the bar the guy grabbed a handful of her ass a few times. My wife is an old school kind of girl, not one of these me too uptight girls.
Now to the "event". Finally she came to the table and sat beside me. The young guy followed a few minutes later. At one point my wife went to the bar to get a drink. When she returned the guy moved over and asked her to sit on his side of the table. It took just a minute for me to notice his left hand was clearly feeling her up under the table. She was wearing a short dress so he could easily get to her pussy. I could see she was getting excited and I noticed her hand move to his lap. She looked over and smiled at me as her right arm started moving. She was giving him a hand job under the table! I could see her arm moving faster and faster, He was twitching like a nervous squirrel. Suddenly he tensed up and her arm slowed down. Still smiling she looked at me and said "honey would you get me some napkins". I went to the bar and got them. She cleaned her hand under the table. We all finished our drinks and we left. Immediately in the car her dress was around her waist and I had half my hand in her pussy as we drove home. She was horny as hell as we fucked.
But the next morning she was like "I can't believe I did that". Not to mention she had to see him all week at work. Little awkward...
