I've always been turned on by this, and have been lucky enough over the years to occasionally meet women who were bent by the same kink, or willing to try something new. Sometimes it's planned, and sometimes it's spur of the moment, but it's always fun. Got caught a few times, but it was a serious issue only once, on a Texas gulf beach. The lady I was with and I just barely talked our way out of being arrested.
Let's see...
On the roof of my parents house
On a balcony overlooking Bourbon Street. She said I didn't have the guts. She was wearing a skirt n no panties. I bent her over the rail. (this draws a large crowd surprisingly fast) Caught by bar manager.
In a hotel elevator (we needed a taller hotel, so I pulled the emergency stop between floors, then took our time)
In a hotel pool
Front lawn of a church (hey, she dared me)
Cemetery
While riding a motorcycle on the interstate (while young and stupid) Only one way to do this. She laid on her back, on the gas tank, and used the gauges as a head rest. It was late at night.
Behind a hanging banner/drape at a rock club
In front of a dozen strangers at a swingers club
In a restaurant ladies bathroom
In a nightclub men's bathroom
On a crowded beach (at night, 4th of July) Got caught by local cops.
While driving my convertible (day time, top down, oral. Trust me, buy a convertible) Many times
In a booth at a sports bar/micro-brewery (everyone was watching the game, couldn't get a waitress, so... BJ)
At a strip club (not VIP)
On the roof of a portable festival stage during a concert (Temptations - Four Tops)
On the DART train (downtown to Plano)
Mile High Club (sex in the bathroom, oral in the seats)
Ferris wheel at the Texas State Fair (be the last in line at the end of the day to get a car to yourself, or try tipping the guy. Tipping is not a sure thing)
Changing room at Victoria's Secret (for $20 the sales girl acted as lookout)
On top of Red Rocks in Las Vegas (take water for the climb, and a towel to lay on)
Back of a taxi (be sure the driver isn't Muslim. Almost got thrown out of a cab onto the left lane of Central Expressway. London cabs are very roomy)
On the open vestibule of a moving train (best way to travel, but amtrak sucks)
Top deck of a parking structure at DFW (before 9-11 of course)
On the Joe Ratcliff walking bridge over 635 near Josey Ln. BJ first time, then we went back a few months later. (she kept saying "when's my turn?")
At a park (Walnut Hill n Greenville)
At a park (Marsh Lane just north of the police station)
On the 9th green of a golf course (highly recommend this one. Go at night. Take a blanket & some wine)
Realtor's open house (almost too easy)
Time share sales tour (getting rid of the salesman is almost impossible)
In a tent at Bass Pro Shop. Got caught by sales person.
Movie theater (both Hollywood and porn type. Back row is recommended)
Always looking for the next one, new "partners in crime", and new ideas!
