The kinkiest thing you and your wife have done in public

Blowjob driving down Highway 97. Fucked in a bird blind at a bird sanctuary with people walking around. We had to stop for a bit before they left and we finished. Bowjob in an elevator in Hawaii and on a balcony in Wakiki. Fucked on a sand bar in the river the day before going to Basic Training.
 
First wife when we were around 18 or 19 had been talking to this old guy on the phone and he seemed really interested so we met him one night in Columbia SC at his motel room. We had talked about going to a drive in. Drove there in my four speed mini pickup and shirt had on micro mini skirt no panties. She sat in the middle. It was a bit chilly that night so I had the truck running with some heat. I thought we better try something to break the ice so I suggested she slide down in the seat and use the shifter as a vibrator. She did and really got into it. He started to touch her button which was totally exposed and she slid right down on that shifter. It was only a minute later she had nothing on and someone walked by curious so we decided back to his room. She carried her clothes in and we got down to business. Even double vag penetration. It was a good night.
