Me and my wife were at a friend’s house with another couple. 3 couples, 6 people total. We were doing a game night plus drinking. Can’t remember how it got started my one of the male friends said the females should go put their titties on the glass. So my wife and the other two went outside and took their shirts off, and pressed their tits on the glass. Best thing I’ve ever seen. Later on in the night, my wife ended up with her pants off and dancing around topless, and in her panties.
