First time for both myself and my wife was boring, probably parents basement like most ?. First time swinging was at friends of ours pool. The husband and I both got out, probably headed to the cooler to grab another beer. My wife was climbing the ladder and the other wife, standing behind her, pushed her finger into my wife. My wife stepped back with a look of shock on her face. She looked at me and said, “**** just stuck her finger in my pussy.” I told her to roll with it if she liked it. The other husband and I watched my wife get fingered for what seemed like forever, probably 5 minutes, until we heard their kid come through the gate. Great night that set the tone for many more with them.
