Drunken night out led to me becoming a cuck

My wife and I are in our mid 40s. Still in pretty good shape. Her more than me. I like beer a little too much. She is a high school teacher. She is small but very curvy. Dark hair. White but darker skin. We are pretty vanilla when it comes to sex life. Pretty normal married routine. Maybe would do it once a month but nothing too kinky. She is not a big drinker. But we try to go out without kids at least once a month. 

We went out for a nice meal. She had quite a bit of wine at dinner. Then as espresso martini for dessert. Which was aggressive for her. I wanted to go home but she wanted to go out for a couple of more drinks. The restaurant happened to be in a pretty rough neighborhood but did have good food. We ended up going to the nearest bar which turned out to be a complete dive bar. Mainly guys. Smoking inside which is illegal in California but apparently was not enforced here. 

We ordered some beers. At this point I noticed she was quite drunk. And getting quite a bit of attention in the bar. She was looking really cute. In a shortish skirt and a shirt with boots on. A seedy looking big guy came over and started chatting. He seemed nice enough, Just making conversation. But proceeded to buy us shots. At this point I felt like we both had enough but my wife just downed hers. 

The night continued and we were just listening to music and hanging out. All of a sudden I felt super floaty. The guy we had been chatting to asked if we wanted to go to a little side room and play cards. We actually love cards but at this point I felt like we really should go. We ended up both getting led to a dark part of the bar. I sat down. 

I watched my wife pick up cards and start to play. I noticed the big guy (mid 50s) ease beside her and sit down and help her with her cards. They were playing with another two guys, He started rubbing her leg. It seemed like she didn't really notice. But she closed her eyes. I could barely move but my eyes were open. I then saw his hand move between her skirt. I saw his fingers move in and out of her. He had moved her panties to the side and was finger fucking her. I had drunk way too much. 

I wasn't sure if my wife thought it was me or not but was clearly out of it but moaning with pleasure. The other two guys were grinning. The big guy removed his fingers from my wife's pussy. He saw I wasn't moving and laughed. He rubbed his fingers under my nose. I couldn't move. All of a sudden he felt for my penis through my pants. What was happening?? I have a pretty small penis. He laughed when he felt me and said 'oh shit man, you have a baby dicklet. Your wife needs a real cock in her'. 

He grabbed my phone and led my wife to the restroom while I stayed. She said she would be fine and just go with it. They came back 10 mins later. I came to my senses. Ordered an uber to take us home. When I was in the uber I checked my phone and it was pictures of my wife. The next day we talked about it and she said she wanted to experience something like that again. She asked me to go down on her. Smelled very musky but was hot.
