My wife and I hit a very crowded club this weekend after driving to a major city from out of state. The club was hopping, with nearly 80+ couples out in the main area hooking up. My wife and I chatted up 2 other couples for a period of about 1 or 2 hours where we had a nice conversation, did some dancing on the dance floor, and then discussed exactly what our preferences and boundaries were. Rules I guess were typical, but it all worked out between us:
Couple 1 - The guy was only interested in his own wife, it was her first time, her idea and she wanted to do something. She was also quite shy however.
Couple 2 - Wife was bi-curious, and heavily pimping her husband. He was along for the ride with a big smile on his face.
Couple 3 (us) - Just in it for the voyeurism/exhibitionism. Wife did have some bi-curious moments.
All was just fine and settled, everyone had their roles and we set off upstairs to get it on finally. However, as we climbed up into a little bedroom loft in the club, another random couple out of the blue just interjected themselves and climbed up with us.
The female of the couple got naked and got into participating with the other two girls, pushing far more than they had already said they were comfortable with, prompting one girl to say "Who the fuck are you?" finally. Everyone assumed they had already been invited by someone else. The guy of the couple kept fondling my wife's ass from behind while we were getting it on, and blocking our view of the show to which we were expecting. It took 3 "no's" from her and finally a "get your hands off" from me before he stopped trying for us, and instead he started putting his hands all over the other girls going at it.
By this point I had absolutely no ability to get or stay hard, these party crashers were really harshing the buzz. After the other two wives made it clear they weren't welcome, the guy basically ordered his girl to go suck my cock, of which I had to tell her that it was already booked (my wife was attempting to ride Mr. Softy to get him rolling, to no avail though god bless her).
They finally climbed out of our loft, at which point my own vigor magically came back, and we ended up having a great time in the end with everyone getting what they wanted. But man, WTF?
Has anyone else had a similar party crasher experience? What do you do if you aren't really sure if they should be there? The other two couples with us didn't mind at first, and we were 15 minutes in before the problems started. Is this sort of thing common in clubs? And which is better, just clubs or making regular playdates with just a few couples, we discussed and saw advantages for each, though we are pretty boring for most people.
