What’s the oddest place you’ve had sex in?

in a park in the wooded area on a day when it was drizzing. joggers were running by infrequently and we were in cowgirl. I could not see the joggers but every once in a while she would lay down on my chest wait for the jogger to run by and sit up again. Our shirts were open and we were colthed. I remember how warm her breasts felt on my bare chest everytime she layed down on me.

In a private hot tub on a double date. I (and her ) wanted to have sex in front of the other couple but they were so not into it. We had sex but they mostlly pretended we were not there. I didn't like hot tub sex--have to keep her hips above the water line and concrete is so unyielding compared to a bed
