I went to pick up my wife from her sisters place yesterday. When I arrived her sisters boyfriend answered the door and let me in. We went to the living room where my wife, her sister and 3 of her boyfriends male friends were. It would not have been a big deal except her sister was topless and only wearing panties and my wife was wearing absolutely nothing. When I asked her what was going on she said, sounding a little drunk, her and her sister were trying on some clothes and hadn't had a chance to get dressed yet. I asked if she made it a habit of being naked in front of guys. She told me to relax and that they had seen naked women before. I told her I didn't want my wife parading her tits, ass and pussy around naked in front of everyone. She asked if I was jealous and then told me it was her body and to get used to it. I told her to cover up and she gave me the finger. I told her to at least put panties on like her sister. She then sat on couch and spread her legs and began showing off her pussy to everyone. She then said she has no problem showing off what she is and then sticks one of her fingers in. I asked her to stop and cover up and she told me she would when she was done. Her sister said to just let her do what she wants as we wont be able to stop her. At this time I decided to just let her do what she was doing. There I was along with her sister and 4 guys watching my wife fingering and rubbing herself. It went on for a few minutes before she began moaning and eventually orgasming in front of everyone. She then said to give her a minute and she would get dressed.
She got dressed and we left. When I asked her about it numerous times today she said she didn't want to talk about.
