New Year’s Eve started by going out to some local bars pre gaming with drinks before we hit up the casino where they were hosting a NYE dance club. We were both pretty buzzed by the time we arrived at the casino. We got drinks and headed in to begin dancing. Wife quickly downed both of her mixed drinks so i agreed to go get her some more. The lines at the bars were ridiculously long. I waited about 20 minutes in line, got her 2 more drinks and returned to the dance floor. When i returned, as i was searching for her i noticed she was dancing with a guy and grinding her ass all over him. She is VERY attractive and early in the night when she got dressed for our night out i was wondering why she was dressed a bit more slutty than normal in a short black skirt with a see through crop top shirt and a Lacey bra with her DD tits practically falling out. I was soon going to find out why. I watched for about 5 minutes as she danced with now 2 buff men. Suddenly she turns around from shaking her ass against his dick and starts making out with one of them. My heart skipped out of my chest but i was shockingly turned on. Then i watched as she reached over and felt the other guys dick with her hand over his pants. I can only hope he was as rock hard as i was. I watched as she continued dancing, making out with them, and feeling them up for the next 20 minutes. It was the hottest thing I’ve ever seen! She never saw me watching and i never mentioned it. The sex that night was by far the best we’ve had in 10 years we have been together! Should i tell her what i saw??
