My first experience in a unique place was on a holiday in Crete. After our night out we returned to the hotel and walked across the outdoor pool. It was dark and no one was out there.
My wife surprised me then. She just smiled at me, got nude and jumped into the pool. I followed her and made out with her in it. So we just fucked in the hotel pool where everybody could have seen us.
The second unique place was a busy highway rest stop. Me wife had some wine that night and was very and uncommon horny. I was driving the car and she opend my trousers and put my dick in my mouth. She told me: look how deep I can put it in my mouth. That was very unusual, she doesn't like sucking dick normally

Nevertheless, I drove in the next rest stop to the most rearest parking place and fucked her with open doors. We had a small car, so I was standing outside and she was sitting in the car.
Normally she isn't like this but when she is, phew
