We were at a friends house playing cards vs humanity drinking. They had another couple over that we didn’t know. As the night went on everyone was getting pretty wild and dirty with their responses to the cards. The ladies decided to take a quick break and go outside for a cigarette. I ran to the bathroom and while i was in there got a text from the wife she was really horny. She said that the other two wives were talking about how much they loved boobs and they all had flashed each other outside. I decided that the guys all deserved a view to. We all came back to the table and sat down to continue drinking and playing. After a couple rounds I asked the wives what they do when they go out to smoke. They said smoke and talk. I laughed and said is that all. Friends wife says well sometimes we compare our boobs. I said well I think we all should get to judge them. My wife looks at me and says oh really? I respond to her yes and I think we all should see yours first. I reach over rub her boob through her shirt and can feel how hard her nipple is so I proceed to pull her v neck and bra down so that her boob falls out. Everyone just stares and then the other two wives proceed to pull theirs out so my wife pulls her other one out. The three of them stand up next to each other boobs out so we can see them side by side.
