I suppose this is an extreme form of PDA :)
Last week Dp and I left a restaurant, and as we walked past the house next door but one, there was a couple having full on sex in the driveway!
We walked past just as she'd fallen into the hedge, and went to see if she was ok, as we hadn't twigged what was going on.
It was only when we saw his pasty arse glinting in the moonlight and them trying to resume position that we realised!
Why oh why would you do that??
