Mine is a small hidden clearing in the forrest which was, except for a narrow path, completely surrounded by bushes. I go there at least once a month.
First time we went there Master put the leash at my collar and lead me to it. As we got there I was stripped (I was just wearing a light summer dress) and crawled naked and on all fours to a big blanket Mistress had put down there.
I kneeled there in the moonlight and rubbed my pussy while fingering my butthole. It was such a magical feeling, so natural and primeval.
It was in summer and quite warm, but every time we go for a walk and come across the clearing I remember this wonderful orgasms I had there. I just stand there, close my eyes and feel completely down to earth
