Where is the naughtiest place to have sex?

try a fitting room at a dept store.

It's fun to do it at the 18th hole of a golf course ! . But don't get caught, or you'll be sited for indecent exposure .

Try out the beach. At night. Exactly on a spot where water go back to sea because of the sequences of waves strikes. Damn you will love it.

My first time was on my girls roof in the middle of winter... fun times

I've always been a fan of the park, in some secluded area. Depending on how much you want to be naughty, I guess you decide how secluded! Usually the thrill of the chance of getting caught is part of what makes public sex so hot. You've got to decide how much risk you are willing to take. The dressing room at a clothing store is another favorite of mine.

-car wash
-elevator
- stair case at an office building
- masseuse tables at all-inclusive resort at night
- conveyor belt at airport

I remember that my ex and I had sex in a pool. oh and it was in the middle of the day so it was fun.

You know those "open houses", mostly in new subdivisions? Yeah. That'd be an awesome place. ;)
