I've told this before, but it's still pretty good (IMHO.) BTW, this took place almost 37 years ago. My wife and I have been married over 35 years, are both in our late 50s, and don't really do that sort of thing anymore. (Rather, I'm up for it, but she's not interested.) Anyway, here goes... "The best one my wife and I have had was back when we were engaged. Her family lived near Tacoma and we were visiting (from Oregon) for the weekend. Saturday was a beautiful late spring day, so the two of us went for a drive up into Mt. Rainier National Park. The Alpine Lupin was in bloom and all the hillsides were riots of color. A couple miles past Paradise Lodge, we pulled over in a large roadside viewpoint (parking for several dozen cars and RVs), grabbed a blanket, and walking off into the wild. We walked downhill from the viewpoint, across a small stream, and up the opposite hillside. We spread out the blanket (which was multi-colored and, coincidentally blended in with the Lupin blossoms rather nicely), got completely undressed, and proceeded for fuck each other’s brains out. We are about 200 yards in a direct line from the viewpoint and in full view of anyone there. While we were probably too small to notice from the parking area with the naked eye, anyone with a modest set of binoculars would have had a spectacular view of us. We fucked and petted and fucked and petted and... well, you get the idea... for well over an hour. During that time, I conservative estimate that upwards of 300 people had the opportunity to watch us perform. When we finished and got back to the car, there was no round of applause, no park rangers waiting to arrest us for public indecency, nothing. Nobody batted an eye. If any of the people that were there when we got back had seen us, on one mentioned it. Still, I'm pretty confident that a number of folks got an eyeful!"
I dated a bar manager. The bar was on a street with nothing but bars and a hotel. I would pick him up to bring him home from work after all the bars were closed. Sometimes he would open the door to me, and immediately push me to my knees to suck him off. Sometimes he'd fuck me in the doorway. There was a little stool near the door for a bouncer who'd be long gone by then. Sometimes he'd bend me over that stool, pull down my panties and spank me bare asset with the door open. Once, I lost something in the car and went out to look for it. He came out behind me, and while I knelt in the seat, facing the other door, he entered me. The angle was just perfect and I almost came right away. He'd always just stop moving and play normal when police would drive past on the one-way street. There were frequent patrols.
Florida beach, college spring break, middle of the night, with a girlfriend and some guys we just met. Not very creative or original, but fun to try once. We got in the doggie position, in ankle deep water. Even less creative and original: Bourbon Street balcony blow job on Fat Tuesday. Best so far: On a pier with a small lighthouse, at sunset, in sight of the little town's waterfront, but nobody was close enough to be sure we were doing anything more than dry humping. I just lifted the front of my skirt a little, and he unzipped.
