Some friends asked my wife and I to go on a four night five day cruise from Miami to the Caribbean to celebrate the wives 40th birthday. It was going to be five couples celebrating the girls all turning 40 that year.
Unfortunately due to my schedule I was unable to go. My wife asked if she could go alone and if I would stay home with the kids. We have been married for thirteen years and have three children and we have a very good marriage. I am a little insecure and used to be the jealous type, however with my wife I rarely get jealous because she is a wonderful trustworthy person. However, when she was in college and a few years after college she had quite a wild side. Therefore, there is always this little bit of doubt that if she was in the right situation where alcohol and partying were involved that she might do something that I would not approve of, and at 40 she can still turn heads when she walks into a room.
After careful consideration I agreed to let her go on the cruise. I talked to her about my insecurities and she assured me nothing would happen. I told her that she had my approval to do anything she wanted to do sexually, as long as it was with two or more guys at once and they all wore condoms. She was shocked and asked why in the world would I say that? I explained my rationale, if she hooked up with some guy, that she and he may start to feel something for each other and it could get messy. However if she fucked two or more guys she would be doing it just to get a good fucking and would not be tied emotionally to the guys. My wife being a slut is a turn on to me but my wife becoming emotionally attached and having an affair with some guy is not at all what I want to happen. She accepted my rationale and assured me that nothing was going to happen anyway.
After she returned from the trip everything was fine, she told me all about the trip, that she had a great time and that nothing had happened that I would not have approved of. I asked what that meant and she said she was just kidding so I forgot all about it. Then, one night when we were about to have one of our "sex" nights, that's where she dresses up in sexy outfits and does her hair for the part and we role play sexual situations. Usually the scenes are of my sexual fantasies...me and some other unknown guy(s) (me and a dildo) fucking a college girl or sex starved MILF (her). Sometimes she is a prisoner and I am a guard, or perhaps I am a fraternity brother(s) deciding whether she can be a "little sister" to our frat or sometimes she is a cock starved housewife fucking three or four college students. It can get pretty intense and is a whole lot of fun.
Anyway, we start fooling around and she is looking a little nervous and tells me that something did happen on the cruise, and that she has felt really guilty for not telling me right away. But she had to get it off her chest so to speak. She said she had a threesome with two guys on the cruise. She said she felt really slutty afterwards but it was fun and that was the end of it, she didn't even remember their names. She said she was really sorry, she didn't plan to do anything but the guys were extremely sexy young Italian guys (guys with the looks she really likes), she was drunk and it just happened.
