We love the great outdoors, especially dangerous sex (with real risk of being discovered) on a warm, sunny day:
In the woods of course
In our back yard
In the back seat of my car in a crowded parking garage
At a crowded beach behind the dunes
At the water's edge of a deserted beach
At a crowded lake waterfront in waist deep water under a dock
On a sandy river bank in a remote area counting on no other canoes passing by us for a while
On a remote muddy river bank after running naked and sliding long distances in the mud for an hour
In the bottom of a canoe pulled up on the shore of a lake full of boats
In a neighbor's pool at 3am
In a shower stall of the Women's Room at a beach park, with many women coming and going
In a bathroom stall at a big airport
In a bathroom on an airliner in flight--pretty tight, but possible, and fun during turbulence
At a summer camp waterfront at midnight with dozens of other drunken, naked camp counselors of both sexes right before the camp director busted us
