My ex and I went to a couple of on-premise swingers clubs in the ny area while we were together, and they all totally skeeved me out. Le Trapeze was full of old ugly people and they had a buffet table that they were all standing there naked eating off of. This guy's package was hovering precariously close to the salsa bowl, and I remember actually gagging when I noticed it.
There was also a strip club in Queens right near the 59th st. bridge that used to have a back room swingers party on the weekends; not sure if the place is even open anymore. HUGE sausagefest. We went there twice - the first time, some chick started mimicking my cum noises and declaring to everyone in the room that I was faking it and that she was a woman so she knew what she was talking about (I wasn't faking). The next and last time we went I was the only girl there, and as soon as we walked in a bunch of horny guys started lunging towards me like wild animals.... I have no idea what they were all doing in there alone together before we arrived, but it was as though they were all lying in wait or something. It was super creepy because the room was very dark and I couldn't even see anyone until they were right on top of me. Thank God I wasn't by myself because as far as I could tell there wasn't any security to speak of. Apparently, the strippers who worked in the club would wander back there from time to time and perform extras for guys and couples, but I never saw any of them back there.
