My married friends and I,3 couples try to go for a night on the town together about once a month. We had favorite hangouts and dance the evening away. We always dance with each other's wife as well as our on spose. This night my friend wasn't holding his liquor well so me and the other guy were taking turns dancing with the 3 wives. My wife went to the restroom I was dancing with the wife whose husband was laid out in the booth. This wife was hot tonight and the only wife that hadn't had children yet so she is very attractive. She rubs her tits, and keeps grabbing my butt like she hasn't ever behaved before. I get nervous and at the end of the song I took a bathroom break. When I come out of the bathroom this wife is waiting. She takes me by the arm and pulls me in the ladies room into a stall. We start kissing and she unzips me and has me hard. She straddles me and bucks hard. After a couple of minutes i unload in her. We get dressed and I sneak out. After hanging out about an hour longer we all get a cab and go home. As always I had sex with my wife after we got home. We still do our hangout but haven't had another fling yet. She and I know what we will do if we get the chance.
