Strangest place you've ...

Victoria's Secret Dressing room.

On a flower cutting table at a florist shop

In a walkin refrigerator of a restaurant during a busy lunchtime rush.

Not too strange as a location , but used to see a lady downtown high rise up towards top , bed was in front of windows with no curtains , so anyone in building across the street , could have been watching . Or La Quinta where I know 6 other guys were watching ! Or Ramada with the lady's "cousin" sitting on the next bed over "watching tv" !

In a moving car while driving

On a park bench just off the hike and bike trail overlooking Lady Bird Lake, northern shore between MoPac and Lamar. This was after several hours fondling each other under a blanket to stay entertained during a so-so performance of The Most Happy Fella at Zilker Hilltop. Roughly 1980 or so.

BJ in the billiard room of Dave and Busters, near closing time. Two of her friends provided cover while she paid her debt. I think she tanked the game deliberately. I was good with that. Nailed her Greek in the parking lot later.

The signal/light tower at the end of the runway at Lowry AFB (no longer exists) while flight ops were active. Could hear her cum even over the sound of jets. We barely evaded the AP's after we were reported. One of the craziest lovers I ever had. A true redhead.

This happened back in 68 or 69, I took a girl on a overnight fishing trip with my dad, we didn't have a tent so we were all laying in the back of my dad's truck, and I know he knew, but he never questioned me, some of the slowest sex I ever had.
