Been to 5 versions of the "Orgy" but never actually a bona fide orgy of description. I'd imagine its a soulless encounter, like Gamorrah of text. Intimacy has soul, nuance, a spirit of the imp, the physical alone has none of that.
Once upon a time in the 70th we had no pool. We had a quarry pond outside the village. When the sun went down and the families left, the moon comes up : we had our own free swinger club. Eberybody knew it, but nobody made a mess !!!
