Who ever has been to a Spanish SW Club knows most of these sounds are real. Furthermore, if there were clubs that had a special room linked to hear live the sounds in there, guaranteed it would be amazing! Of course with the consent of the couples in such a room, nothing more than great pleasure for both sides, listener and exhibitionists. The last time I was there with my ex-girlfriend and that sounds of some couples, really got us in the mood!
One of my previous jobs was working as a security guard in an apartment building. Since it was in a college town, most of the residents there were young students. I remember the first night I started doing my patrols, I overheard a girl having sex in her apartment. It was a lesbian couple since she always had a female friend over and I heard two distinct female voices. I listened for several minutes before continuing my patrol. I got so excited hearing their sexual trist that from then on, I would try to record any other sexual encounter when I could. Over the years of my tenure at that job I've heard quite a few couple's sexual adventures.
