My wife and I got a hotel room with a pool one night and we were drinking her girlfriend dropped by there was a guy in the pool my wife was very obviously into, we went back to our room with her girlfriend and we were playing cards then we decided to play truth or dare.
My wife was dared to bring the guy from the pool back to our room and I was dared to act like just a friend and watch them fool around. We took our dares but they ended up going at it full out all night into the morning I was a little jealous and very turned on to watch my wife enjoy and be enjoyed by another man.
I get excited to this day thinking about that night!!
