I remember one night we were out at a dance club. We really didn't plan on any hanky panky. we danced a few dances together and we were standing at the bar and the husband of a couple that had seats at the bar offered my wife his seat. she excepted and the 4 of us started talking about nothing. he and I talked about muscle cars and his wife asked my wife to join her on the dance floor. So as he and I talked we watched them dance. out of no where he asked if my wife was wearing panties ( she had a long dress on) When both ladies danced in front of a ligh you could see through the dress. Not good enough to see if they had panties or not. He said his wife was not wearing any. my wife was wearing panties. Well a few more drinks and some small talk nothing sexual. A slow song comes on and The guy asks my wife to dance. So I asked his and out we went. once again it stayed pretty calm. After the song we went back to the bar. my wife said she was going to the ladies room and would be right back. when she came back he asked if i minded if they danced again and said its up to her and away the went. they sort of got into it and his wife said that her husband thought my wife hot. I said, I can tell. Then she said, did you see what she gave him? I said no? She handed him her panties. he asked her was wearing panties when they danced the first dance. Told her it would be much sexier if she didn't have any on. When we left to go home She told me she gave him her panties. As we drove down the highway I made her pull her dress up so I could see and made her expose her tits. I asked her to stay that way as we past a semi and turned on the inside lights. drove next to the truck for awhile so He got a good look. Ten went home and screwed like crazy
