Tonight at the Swingers Club

My wife and I have been swingers for 10 years. Before we started swinging we laid out our ground rules and have always stuck to them. Well that is until tonight. Our ground rules were simple. We would always do things together, which has lead to many threesomes and a few times with another couple but we'd never ever do a full swap. The few times we played with another couple it was always girl on girl with the guys watching then each respected husband would bang his wife to finish. That went out the window tonight.
