What is the strangest place your characters have ever had sex?

Well, my characters just got done having sex in the Lincoln sitting room of the White House (and they're vampire guests there) so, in light of that, I thought I would just see what other people had done!

Not really that strange, but a treehouse.

On the roof of the local radio station.

In the kitchen. WHOA innovation!

A desert oasis. :D

In an monastery that had been turned into a spa with some suites and rooms, on the last floor. Didn't thought I could maybe toss an monk in the party to see him flush at the debauchery he see.

This year's Nano has my characters living on a farm in the middle of nowhere so with the exception of some al fresco smut, nothing very kinky. But I've been writing about these people since the 90s (it's like fanfic for my own characters, so sad), and the weirdest place I had them have sex was in an office with (unbeknownst to them obviously) the PA system on. The resulting talk with their boss ... well, let's say I just alluded to that ...

Examination table in the doctor's office.
Or, the bondage room with the peep hole into the doctor's office. But that was just oral.

Wracking my brain on this entire series.... I think the MCs from the first book have it with their little tryst in the Unseelie Court.

Now I'm determined to beat that. }:D But first, to make my MCs not hate each other.

...the school....

Inside a bridge in a park. One of the characters was homeless for a while and lived in the hollow space between two layers of the bridge...

Does an alien spaceship count?

Mine rarely have sex in a bed.

Caught receiving a blowjob in a public garden? Check.
Bondage and humiliation play in the same garden? Check.

But the strangest place is probably a Walmart parking lot. They get arrested for that one. O.o

My character's Malic, Cal and Raven were caputured by hunters. They were put in a hole lined with spikes. Malic hates Cal, Cal hates Malic but they both love Raven. They have a menage a trois to settle their despute.

Not so weird, but a character forced himself on my FMC in the backseat of the car while the FMC's ex ( who also raped her, ugh this is a bit complicated ) got out of the car and went inside the gas station's restroom.

I'm trying to do a scene where my two characters are dared into having sex in a fountain at night.
