The group we used to party with were very friendly. My wife and this one guy would be in a dark corner and he would feel her up and they would make out often with her tits out.

His wife and I weren't far behind. That was the first time she had a guy after we got married and the same for his wife. It was also the first time either had a cream pie.

It also wasn't the only time we swapped
