Talk about a wild weekend

We meet this couple a month ago camping. They are around 6 years older than us (she is really attractive)We go to their house to spend a few hours playing games. Ate supper and got into the hot tub. Every one was getting drunk and we decided to play some board games. Gestures was the name of it. Only it was strip gestures lol. Needless to say the girls lost..no undies came off but my wifey was ready to kill me for playing this game She was very uncomfortable with the whole situation. I decided to end the game (to please her) we got back into the hot tub. The other couple jumped in and decided to do the wild thing lol (it was completly pitch black). The wifey was pissed off by this point and I myself was feeling a bit uncomfortable. All of a sudden I feel a strange hand come outta no where and start touching me....I did not know what to do..on one hand It sure had it strong points ( )but I could have saw the wifey moving around and feeling a strange hand on me lol I decided to move the hand back where it belonged. No other attempts was made towards me lol Did I do the wrong thing Should I have left the other girls hand alone and enjoyed myself lol Needless to say the rest of the night went just fine but talk about a night to remember lol Should I have told the wifey about what happened? They seem like a real nice couple (but they might be swingers too) lol The wifey would kill me if I ever tried any crap like that lol
