At the old Santee Building. I was 24, she was 21 and one wild little girl.

in a hospital parking garage in broad daylight in the back of my SUV.....

LLAP,

MANY years ago, en route to Germany.  Half empty plane -- in the days before 110% capacity bookings.  GF and I were heading to Germany for a hiking holiday....  BOOM!

In the restroom of a 747 on the red eye from New York to San Francisco! Sounds crazy now but it was several years ago!

for me. But I saw a few girls in slum, dirty, roach infested apartments. One time one of the girls there even had a baby there with her. A few times at first, in used old cars, sleazy cheap motels and settings.  

Lick Lick,

about 23 years ago .. going through divorce ..  i called those 900 numbers just to talk to a girl ..  well we talked and again this is decades before tinder and even internet dating etc   ... we wind up meeting in an alley behind her mom's home .. messing around in car .. but kinda cramped ..so we go into a garage ..  PITCH black .. couldn't even see myself ..  laying on bare concrete ..  kissing and before either of us even thinking .  we are going at it in missionary for a couple minutes and then over ..  never did see her again.

Clarendon Hotel in PHX, we started in a giant papasan chair, nobody was up there since the rooftop bar had not opened for the day.  We turned the chair around and gave the nearby apartments a show!!  

Looking at some of these responses....

A quickie with an ex in a super busy Potbelly's doesn't seem so exciting anymore lmfao.

On a pay washing machine in the laundry room of my first apartment with my neighbor’s wife. The movement of the washer as the water was surging created an extra thrill. Many years ago, but I still remember.

In the sauna room at a gym

hardwood floor of my Beverly Hills office ..  now that's probably not that unique .. but the woman was .. met online ( mid 90s again early days of chatting on AOL)    turned out to be a high school principal ..  she wore so much over the top makeup it was almost comical ..  so just that one time ..   she told me she would routinely fuck one of the teachers in her school office !     but said no students.....   whew !!    you wonder what truly happened back in the 60s and 70s we just were not aware of and nobody talked about !      

The craziest and hottest place I ever had a quickie was in a TREE! Yes, you read that right, lol. I grew up in the country and snuck down into the woods with my High School boyfriend and took total advantage of each other in the most beautiful, plush, moss covered tree.... Still think about it to this day.
